Passenger lift

Passenger elevator is commonly used to transport passengers.

Freight elevator

Transfer at general dedicated to transport of the goods.

The bed elevator

Bed elevator is usually used to transport in bed patients and nursing staff.

Passenger and cargo dual-use ladder

Passenger and cargo dual-use ladder generally can be used for transporting passengers, can deliver goods again.

The elevator according to the speed of classification

The elevator speed is generally divided into: express ladder, quick ladder and ladder at low speed.

The high-speed elevator

High-speed elevator speed in more than 2 m/s, some call it a class ladder.

Express elevator

Express elevator speed above 1.5 m/s, some call it b class ladder.

Low speed elevator

Low speed elevator speed above 1.01 m/s, some call it the c class ladder. At present most of the residential passenger elevator choose speed 1.0 m/s.

The elevator by dragging system classification

Elevator according to the drag system classification, generally can be divided into ac and dc elevator lift.

Ac elevator

Ac elevator use ac elevator traction machine. Transfer and sundry ladder is commonly ac drive, speed within 0.5 m/s. In the passenger lift ac elevator is commonly used in floor is not very high and the place of use requirement is not high. Such as general civil residence, its speed is generally within 1 m/s.

Dc elevator

Dc elevator, due to its qi car, changing speed, leveling, parking is more stable, fast, used in high-level and the demand is higher. Dc dc fast dc high-speed elevators and elevator and into the elevator, its speed is 1.5 ~ 1.75 m/s, respectively, and 2 ~ 3.5 m/s. Dc dc motor of the lift generally from the electric power supply and control unit.

The elevator control mode classification

The elevator according to control methods of classification, generally divided into semi-automatic and automatic elevator lift.

Semi-automatic elevator

Semi-automatic elevator in three kinds of circumstances: (l) hand since the flat open elevator – is controlled by the axle box handle switch, with automatic flat layer of elevator, goods elevator belong to such more. (2) button from flat to the elevator – is controlled by the button device of the elevator, with automatic flat layer is used to transfer and sundries elevator. (3) from the flat, since the open elevator, the above two kinds of device with automatic doors of the elevator.

Automatic elevator

Automatic elevator also three types: (1) the signal and control the elevator, except with automatic flat layer since the open action, and with both inside and outside layer, automatic orientation, consequent properties, such as car. The elevator should be the driver operation. (2) sets control elevator, except with signal control of elevator performance, also can operate without the driver, so need to increase the hall call reverse car segment. (3) fixation of control, elevator used in ac, dc elevator without driver, basic working status with collection, the difference is hall under the outgoing call signal response.

Set selected control elevator

Collection control elevator is developed on the basis of a signal control, highly automatic control of the elevator, and the signal control of the main difference is that it can achieve without a driver’s operation. It not only have the functions of signal control, but also has automatic control stop time, automatic call service, automatic reverse response and reverse hall calls, and other functions.

The elevator model

So-called model, that is, using a set of letters and Numbers, with simple and straightforward way to lift the main content of basic specifications. China’s ministry of construction standard “JJ4S – 86 model establishment method of the elevator, hydraulic elevator products, the elevator model establishment method.

Intelligent elevator

Intelligent elevator is the use of reasoning and fuzzy logic, the method to develop the knowledge base of expert system is used to determine the most suitable for the reality of the rules, and rules of selected for further processing to determine the best elevator running, at the same time immediately communicate the information to passengers and passengers from physical and psychological conditions and requirements to meet the demand of efficient transport.

The elevator is also called the lift. Is the vertical transportation equipment, is the indispensable transportation equipment in the high-rise building. It rely on electricity, drag a manned or capsules, in the construction of the shaft on the guide rail vertical lifting movement.

The composition of the elevator:

The elevator generally consists of five parts: (1) the shaft and housing; (2) the transmission part p (3) safety device of the elevator parts edition; (5) control part.

Shaft and machine parts:

This is a requirement for normal operation of elevator building parts.

Transmission parts:

Transmission part of the traction machine, is mainly composed of motor and wire rope.

Lifting equipment parts:

Lifting equipment generally includes capsules, the balance of weight, chain, guide rail, the hall.

Safety device

Safety device generally includes speed down device and electrical safety devices.

The control part

Control part is usually refers to the electrical control equipment and the necessary wiring, including control cabinet, excitation and choose layer and etc.

Traction machine:

Commonly known as reducer. It installed in engine rooms, generally above the buildings at the top, is the elevator traction device, it’s pure wheel with wire rope traction capsules and heavy. Traction machine is made up of worm gear reducer, rope, backrest wheel, the brake wheel, motor, base and so on. Dc elevator traction machine, high-speed yuan gear driven directly by the elevator rope round, no reducer device, with the rest of the parts.

The hall:

The door of the elevator door is installed, each layer with organic chess lock on the door and electrical contacts. Passenger lift more for automatic doors, close by open the car door opener to drive the hall door rubber le roll to complete, and the car door is driven by the open closed device on the capsules.

Shaft:

The shaft by the wall, roof and round into a bottomless pit, in the elevator capsules and limited space for weight. To the people, in each layer station entrance.

Wall:

Is the role of casing elevator is separated with the outside world, when the guide rail frame directly installed on the walls around, it should also be under shear. The structure of the casing is divided into enclosed Spaces and type.

Roof:

Top of the shaft is computer room, it is the place where maintenance personnel work. Roof must be closed and will therefore shaft and room is completely isolated. Also has to prevent roof room namely to the role of the shaft. For fast, high speed elevators, in order to obtain good sound insulation effect, often set sound insulation layer on top of the shaft, the shaft top became a double-layer structure.

Pit:

Shaft bottom hole into the ground, used to install buffer, speed limiter, wire rope tension bridle device, etc. Due to the deep ground, therefore require waterproof, it is better for drainage.

Computer room:

Room to install traction machine, electric control panel, speed limiter, etc. Rooms can be set on the top of the shaft, also can be set up in the well by the department. When the room is located in the bottom of the shaft, is under the traction machine type traction way. This way, complex structure, bearing significant buildings, large to shaft size requirement, only in the room can’t use overhead. For most of the elevator, the elliptic all set on top of a shaft. Rooms must have enough area, height, load bearing capacity and good ventilation.

2, the bottom of the elevator Dun, all is the elevator capsules in the control system failure, will miss the first layer flat position and driving down, until the Dun exactly pit stop on the buffer. This rarely happens, but in the event of the consequences will be very serious, large inertia is likely to lead to life-threatening body fracture by ladder. In fact, if the elevator in the process of decline, suddenly drop sharply, elevator safety protection device can make the elevator to stop. It is important to note that the lift falls from start to stop distance is associated with the load of the elevator, so take elevators must not be overloaded.

3, trapped in the elevator of self-help measures. Emergency stop running, reliable elevator have several sets of careful protection device to protect the safety of the passengers, don’t worry about it will continue to fall off. Suddenly stop – a variety of reasons, before not knowing why, any himself managed to escape from the behavior of the venture. When just trapped, if the elevator didn’t call, can use shoot the door Shouting or shoes at the door. If trapped for a long time, the safest way is to keep calm, save energy, and wait for help.

4, elevator management personnel should be how to rescue trapped personnel. When the elevator tiring accident, elevator management staff by phone or message, get in touch with stranded passengers. Be sure to keep calm, patience to wait for rescue of maintenance personnel. Capsules, away from the elevator stop into the room closed the elevator power switch, on the elevator shaft installation disk driver wheel, wheel held on one hard disk driver, another hand brake release lever, gently pry the brake. Observe flat sign, make capsules gradually move to the nearest to the hall door. When braking is verified with layer door key to open the door, the car door, to assist the passengers leave the capsules, and the closed room door.

It is important to note that some of the elevator work come after, directly open the door of the elevator interior or outside. Then on that sometimes the dock on less than layer, jump down, it is very common in life. But this is a very non-standard rescue behavior, because the location of the elevator stop in should not stop layer, it is out of the system failure. So if you don’t cut off the power supply case opened the door, at this time of the one thousand elevator have fault, passengers will appear.

2, when the elevator door open, do not put the hand on the door, prevent door squeezed his hand back, the door is closed, don’t will hand on the edge of the door, lest affect close action even squeezed his hand. With children, it shall hold children with hand tensed or ride the elevator.

3, when the elevator should keep a certain distance with the elevator door, to be on the safe side, because in the operation of the elevator, the elevator door connected to the shaft, relative speed is very fast, the elevator door one thousand, near the door of the passengers will be quite dangerous.

4, don’t jump in the elevator. The elevator capsules on set up a lot of safety protection switch. If hopping in the car, the car will be heavily skewed, may cause protection switch action, protect the elevator into the state. If that were to happen, the elevator will be emergency stop, trapping by ladder personnel.

5, the door a lot of people use body against the door, although there is no danger, but if you press too long, the elevator control section will think the elevator is out of the fault. Is likely to call the police, or even stop. So more appropriate approach, is you in later, according to the open button.

Especially what need reminds is, some people the whole stand at the door, blocking the elevator door, this is dangerous. Because the elevator is safe, outside is safe. But you stood on the boundary between the two space place, if say this time, everyone is called opens up the car, this person will be cut. So this is a very dangerous place, should not stay in this place along the border.

6, some units use a goods elevator for passenger elevator is not allowed.

Goods elevator and passenger elevator difference is its decoration, or its comfort is less. Vibration and noise of the indicators have no special requirements are put forward. In addition there is a goods elevator, is absolutely cannot away with, is super area. Because sometimes the factory do this kind of products are comparatively light, and it wants capsules is done a bit bigger, so after the approval of relevant departments, the capsules area is bigger than the standard. If the goods elevator at ladder, overload will occur.

Relatives and relatives speak of the matter, said: “the elevator in the building three days two head bad, someone carrying goods, put on the top of the elevator door, do not alarm bell rang, and the family is decorated, even in the elevator and decorate a garbage, also don’t know who did it. The elevator maintenance man every time after completion, both in the elevator stick a warning, not to be flung hard into the elevator, but do not work, some people figure he is convenient, also don’t want to think the elevator is out of order, who all don’t convenient.”

In fact, the use of the elevator, also is not only the civilization etiquette or convenient, more closely connected and security. Recently, the elevator safety accident frequency, the former two days have elevators overweight, but 18 Under the passengers who will not, as a result, the elevator straight from the ground floor fell to 1 layer, let every a person concerned. According to professional personage analysis, this is the problem of improper use. I think to take the elevator civilization and safety, not black not white. Because some people’s mind, there is no elevator accident and closely related to the improper use of consciousness, it is precisely these unconscious, shorten the service life of the elevator, buried under the safe hidden trouble. People only a consensus on this question, can consciously voluntarily established love civilization atmosphere of the lift.

Tournament competition activities on October 17 to 18, 2015, in the center of the city, activities for two days. From zhuhai, with permission of the registration of fe Intel elevator co., LTD in anhui province, fuyang Mr Lingli elevator co., LTD., fuyang jia yu mechanical and electrical equipment co., LTD. And other 15 teams took part in the competition.

Competition project is divided into theoretical knowledge written test, interview reply and practical operation skills examination of three parts, the content involved in laws, regulations, standards and special equipment maintenance and maintenance rules on the use of the elevator, related technical specifications, operation skills test common fault analysis, eliminate the elevator maintenance, security component testing, adjustment skills such as operational projects.

Tournament preliminaries and semi-finals two competition points, through the preliminary selection of 15 teams, there are 6 teams and 18 excellent players will enter, finally the fierce conflicts between the heats, set foot mechanical and electrical equipment co., LTD in anhui province, fuyang Mr Lingli elevator co., LTD., anhui top down the elevator engineering co., LTD., in turn, has won the top three preliminary outstanding group team. Su Hui, wang wei, liu hai-yang zhang, Jiang Yongtian, TaoXueShan six players won the top three skilled players in turn. Won the top 2 outstanding group team and skilled players will represent fuyang city in the province the first elevator maintenance workers final event.

Competition in the process, the players enthusiasm, cool, good at thinking, rigorous operation, troubleshooting a race against time. From anhui province top down the elevator engineering co., LTD., the maintenance personnel of wang wei said, the game has certain difficulty, but to study at ordinary times accumulated rich work experience, skilled completed troubleshooting tasks. When it comes to harvest, he said happily: “this is the first time hosting games, met a lot in the game masters, increased knowledge, learn from them a lot of knowledge, have a lot of help to the following job.”

The competition, enhance the interaction between the city’s various elevator maintenance unit, built for the workers to promote “learning, research, thought, and” skill ratio force platform, for further promoting the province elevator safety “4 + 2” system construction, and guide the city’s elevator maintenance units and workers to master the necessary laws and regulations, business knowledge and skills operation level, improve safety consciousness, responsibility consciousness, quality consciousness and service ability, better service to the society and the people take the ladder safety escort, to build peace in fuyang, play better and more important role to build a harmonious society.

“Regulations need to be modified. Peng Liang said, at present the elevator safety management, mainly according to the laws and regulations is the special equipment safety supervision regulations “(state council order no. 373). But due to the elevator safety work related to the elevator, property management, construction, owners and the owners’ committee, and other stakeholders, multiple departments, must all parties, the interaction between the various departments, to be effective to carry out the security responsibility, ensuring the safety of the elevator. , he argues, should according to the law of the People’s Republic of China property law “as soon as possible, the production safety law of the People’s Republic of China, the” special equipment safety supervision regulations “and other laws and regulations, draw lessons from Beijing, Shanghai, shenzhen, wuxi and other places of advanced management experience, to formulate the elevator safety supervision and management measures of chengdu, to carry out the elevator security responsibility, specifications use the elevator. Especially in view of the old house, new house, the owners’ committee estate, without the owners’ committee building, etc, are targeted and specific rules and regulations. The chengdu evening news reporter Zhang Zhaohua

How old elevator repair, how to change?

City pledges inspect bureau

The draft is drafting related

Chengdu scrapped overage elevator? How to change? Who will pay? Elevator maintenance, security, how to get a better safeguard? The chengdu evening news reporter learned yesterday, the elevator safety supervision and management regulations of chengdu into municipal government legislation research program this year, the city pledges inspect bureau is drafting relevant draft, or to clear old elevator maintenance to replace the specific measures. The draft is expected to come this year.

Zhang Ke said, vice President of the special equipment inspection institute of chengdu, Beijing, Shanghai etc. Use the elevator before early city of old elevator replacement problem, has taken some measures, chengdu in drafting relevant draft, from these experiences can be reference, as housing and construction departments linkage.

Beijing: the fixed number of year must change the ladder of Beijing in “residential elevator use fixed number of year rule”, building a single elevators using 15 years’ time, more elevators using time reached 18 years, host and other major parts wear, the equipment has been more than three times overhaul, maintenance engineering investment cost more than equipment depreciation again salvage value must be replaced new ladder.

Nanjing: in ladder developers to pay in order to reassure residents, nanjing explicitly proposed overhaul of the lift, retrofit costs, separately from the original maintenance fund, stipulated by the owner no longer pay at the same time, the development of related enterprises “pay” in advance.

1, the elevator will fall off?

Firefighters said the normal use of the elevator won’t happen to fall commonly, usually at the bottom of the elevator safety for device, make the elevator won’t fall. Power failure, safety device will not fail, so the elevator won’t slip out of the elevator slot. In the operation of the forced grilled door, hopping on the elevator, three main causes of the unexpected overload. In fact, though by experts test a grilled door, jump in the elevator does not directly cause the elevator to fall, but will make the normal operation of the elevator suddenly take emergency measures, emergency stop led to the lock can’t open the elevator door; Manned, and overweight cargo is the direct cause of falling elevators.

2, trapped inside the elevator will suffocate?

In elevator in the narrow, once trapped for a long time, many people worry that could lead to suffocation. Firefighters said that currently in use the elevator must meet the ventilation requirements to run the market, any elevator vents, is not sealed. In addition, even if the elevator power, ventilation equipment also has a standby power supply. Elevator has a lot of moving parts, some of the connection position, such as the elevator wall and joint has a gap on the top of the elevator, generally we breathe need enough.

3, trapped elevator passengers can forcibly open?

Firemen also remind you that the elevator without doesn’t mean watching falling, there is no danger, if passengers forced opens the door, not only causes the unnatural power, more will increase the abnormal wear of the elevator wire rope, brake, etc, affect the brake devices such as the effect of emergency braking, then there is a fall hazard. In fact, the primary cause of falling elevators, it is long time friction loss or artificial damage, so the elevator average just need maintenance once every 15 days, when we take the elevator, whether should also be concerned about the tools used by test on time, whether there is any unsafe factors.

4, trapped elevator do the safest?

“Keep calm, it is in order to correctly for help, get help and rescue” as soon as possible. Firefighters said, the elevator has the emergency telephone or intercom system, can make the contact with the outside world, can also according to the index plate alarm bell alarm. Covers most of the elevator signal, trapped people can call safety inspection on the sign “lift maintenance phone domain urgent repair telephone, to professional elevator maintenance personnel for help, also can call 119 or 110. Call, to firefighters or police for help. In addition, also can use hand on the door, knocked and knocked,” hit send distress signal.
