How to use the elevator safely (Elevator Safety Knowledge)

ONE- civilized waiting for the elevator

  1. Correctly press the up or down buttons at the door, not both at the same time. If you press the up or down button at the same time, it will make the elevator useless and waste the waiting time and electricity. When the elevator arrives, if there are multiple parallel elevators, the arrival lights of any one of them shine and the arrival bell rings, inviting you to wait at the entrance.
  2. After the elevator closes, passengers first go down and then go up. If any passengers come out of the car, you should stand on both sides to facilitate their evacuation and then enter the car.
  3. If the car is full, please wait patiently for the next elevator to arrive.
  4. When the elevator closes, don’t push your hands or other objects between the two doors
  5. In case of fire or other circumstances, people in the building shall evacuate through the stairway. Do not take the elevator, in case the power of the elevator is damaged, taking the elevator will be trapped in the car.

 

TWO- Correct access to the elevator car

  1. Get in and out of the car quickly and safely, do not stay at the door. Passengers standing at the door should leave the car first.
  2. Press the destination floor button correctly to ensure you can reach the aim floor.
  3. If the number of passengers in the car is moderate, you can move deep into the car to facilitate other passengers.
  4. Passengers with children need to take good care of children, and passengers with pets should prevent pets from moving alone.
  5. Keep a distance from the elevator door. When open and close door, special attention should be paid to prevent clothing or personal belongings from being crowded by the elevator door.
  6. If you need the elevator door to keep open, you should hold down the open button. If you need to carry your belongings, you can ask other passengers to hold down the open button

 

THREE- Take the elevator correctly

  1. Pay attention to check the elevator on the presence of << safety inspection >> label, and whether in the period of validity, don’t blind to take elevator such as do not conform to the requirements of the elevator equipment, to reflect the local Special Equipment Safety Supervision Department.
  2. Stand as close as possible to the wall of the car and put your hands on the car arms if elevator with it.
  3. Most elevator injuries occur at the door or in the hoistway. When the elevator fails, stay away from these two positions can keep you safe.
  4. The elevator door (the floor of the car door) is a very dangerous place and cannot stay for long
  5. Try to get in and out as quickly as possible, and don’t linger between the door and the door. Don’t lean against the elevator door or floor door while waiting and riding
  6. Gently press the call button or choose the operation box car floor layer button, indicator, quietly waiting for the elevator, don’t jump in the car, or with hard, sharp tap button or press the button again and again, and may not hinder the movement of the door by hand or by body
  7. Attention should be paid to the handling of articles. For transparent objects such as glass, when entering or leaving the car wearing thin long skirts, high heels and carrying umbrellas, careful attention should be paid to the accident caused by clamping.
  8. Do not carry inflammable, explosive or corrosive dangerous goods in the elevator.

Everything you should know about elevator brake

The elevator brake generates two-way electromagnetic thrust when electrified, which makes the brake mechanism separate from the rotating part of the motor. When the power is off, the electromagnetic force disappears. Under the action of the applied brake spring pressure, the friction-type brake of the electric loss brake is formed. It is mainly with escalators traction drive motor on formation of escalator with electromagnetic brake three-phase asynchronous motor, widely used in parking can achieve smooth and rapid start and brake when electricity safety.

Brake is an important safety device of elevator. Its safety and reliability is one of the important factors to ensure the elevator running safety.

The working principle of elevator brake

When the elevator is at rest, no current passes through the coil of the traction motor and the electromagnetic elevator brake. At this time, because there is no attraction between the electromagnetic iron core, the brake pad tightens the brake wheel under the action of brake spring pressure to ensure the motor does not rotate; The moment when the traction motor is electrically rotating, the coil in the brake electromagnet is connected with current at the same time, and the electromagnetic core is magnetized and absorbed rapidly, driving the brake arm to force its brake spring, the brake tile is opened and completely separated from the brake wheel, so that the elevator could be running; When the elevator car stop the required floor, the traction motor loses power, and the coil in the brake electromagnet also lost power , and the magnetic force in the electromagnetic core disappears rapidly. Then the core is reset by the brake arm under the action of the brake spring, make the brake tile hold the brake wheel again and the elevator stops running.

 

Useful conditions

  1. No more than 1000 m altitude, air relative humidity is not more than 80%, environment temperature + 40 ℃ ~ 15 ℃.
  2. There is no gas or dust in the surrounding environment that can corrode metal and break insulation.
  3. Insulation class B, protection class IP55, voltage fluctuation no more than + or – 5%.
  4. The working mode is S1 continuous working system.
  5. Working voltage AC220V/DC110V

 

 Function of elevator brake

(1) It can make the elevator in operation stop the car automatically when the power is cut off.

(2) When the elevator stops running, the brake should be able to keep the car at rest and position unchanged under 125% rated load.

Installation method of Escalator Safety Brush

The escalator brush is also known as apron plate clamping device. It is fixed in the escalator handrail wall and class clearance above the dust, anti – clipping brush combination. There is a certain gap between steps and step with apron board, Generally the gap will not be greater than 4 mm, but in such a small gap also can make clothes or the child’s fingers, shoes divided into the damage, so install security brush for each escalator equipment is necessary.

What is the reason for the deviation of escalator steps?

What is the reason for the deviation of escalator steps?

 

The escalator consists of steps traction chains, step guide rail system, drive device, tension device, and handrail device and metal structure. The structure includes: steps, kick plate, bracket and auxiliary wheel. Escalator is continuous work, therefore, in the stream of people concentrated in public places, shops, railway stations, airports, docks, the place such as buildings and underground railway station, to transport a large number of people in a shorter time, using the escalator has more advantageous than using intermittent working elevator.

The steps are integral and modular. The integral die casting is made of aluminum alloy with high precision, light weight and high processing speed. The modular echelon is composed of steps, kicking plate, supporting frame and other parts, with large weight and poor precision. It is a product of small die-casting capacity and is gradually replaced by integral echelon.

The steps move horizontally at the passenger entrance (for passengers to get on the stairs) and gradually form the steps. The steps fade away near the exit and the steps move horizontally again. These movements are realized by the steps of the main wheel and the auxiliary wheel respectively walking along different steps of the guide way.

Under the escalator room has two springs, is for adjusting the escalator cascade running deviation device, if can’t adjust well, that’s different cascade big chain long, need to change the big chains.

The escalator is generally inclined. A pedestrian standing on one end of an escalator will be automatically taken to the other end of the escalator and the steps will remain level all the way. Escalator step has with cascade synchronous moving in on both sides armrest, fu grip for users. Escalators can always walk in one direction, but most can be controlled by managers according to the needs of time, people and so on. Another type of pedestrian conveyance similar to escalators is the automatic walkway. The main difference between the two is that there are no steps on the automatic pedestrian path. Most only walk on the flat ground, or lean slightly.

The escalator consists of a stairway (variable plate conveyor) and an arm rest (deformed belt conveyor) on both sides. Its main components are cascade, traction chain and sprocket, guide rail system, the main drive system (including motor, speed reducer, brake, and the middle transmission links, etc.) drives main shaft, step and tension device, skeleton, comb plate, escalator handrail system and electrical system, etc. The staircase gradually forms a staircase after horizontal movement towards the passenger entrance (facilitating passengers to ascend the stairs). The steps close to the entrance gradually disappear and the steps move horizontally again. These movements are realized by the steps of the main wheel and the auxiliary wheel respectively walking along different steps of the guide way.

What is the escalator anti-climbing device (Anti-climb Barriers)?

When the escalator is more than 12.5 cm adjacent to the wall, it should be on the escalator or automatic.

A blocking device installed at the upper and lower end of a sidewalk.

Generally, the escalator anti-climbing device on the market is mostly made of acrylic material, and its characteristics are as follows:

  1. The heat deformation temperature of ordinary acrylic sheets is about 100 degrees, and the continuous use temperature should not be higher than 90 degrees.
  2. Acrylic sheets are easy to generate static electricity and absorb dust. When cleaning with soft cotton cloth dip 1% soap water can be wiped.
  3. The surface hardness of acrylic sheets is equivalent to aluminum materials. When used or processed, please be careful to avoid surface scratches. If you get scratched,

The original glossy surface can be restored by polishing.

What is the escalator anti-climbing device?

Installation necessity

In public elevators, there are no shortages of children chasing after play. Although many beside the escalators are “forbidden climbing play”, “children must be under adult supervision on” logo, but the installation of the elevator armrests prevent climbing, will also reduce the risk of accidents.

So to go against the wall adjacent to more than 12.5cm, on escalators or sidewalks, bottom department shall install block device, to prevent people from entering the outer cover plate area, thus fall accident, etc.

Method of use

If there is a risk of a person falling, appropriate measures should be taken to prevent the person from climbing onto the outside of the handrail device. In order to ensure this, escalators and moving sidewalks outside cover plate should be installed on the fortification climb the device (see right-hand chart), climbing device located above ground plane h9 (1000 + 50 mm), lower fellowship with outer cover plate, parallel to the outer cover plate on the direction of extension of l5 should not be less than 1000 mm in length, and shall ensure that within the scope of this length without stepping on foot.

How to avoid elevator car door failure?

The failure of elevator door system accounts for a large proportion of the total failure of elevator, among which the door mechanism is the most frequently running system in the work of elevator, which is directly related to the safe and reliable operation of elevator. The failure rate of car door system also accounts for a considerable proportion in the failure rate of door system. The main reason is that the installation technology of door system is not up to the design requirement. The interpretation of the car door below is shared.

  1. The door opener, car door, safety security sensor, and the installation of the door knife have been completed by the installation team at the time of maintenance.
  2. The adjustment of car door is the premise of door system adjustment. Only after the door is adjusted, will the door be calibrated.
  3. First remove dust from the door with a pair of fan, and then grind the track of the door with more than 300# sandpaper to ensure the flexible operation of the door.
  4. The door must be adjusted to:
  • The distance between the door plate and the floor sill is 4mm;
  • The distance between the door and the front wall of the car is 4-6mm (not too small). Check method is to use just ruler on two pieces of door plank up and down side, whether it is balance.
  • The front and side of the door must be vertical to ensure that the door is properly sewn when it closed, meanwhile when opened; it joined to the front of the car. After adjusting the car door, you can open and close the door manually. The whole switch process should be easy and smooth.
  1. Adjust the security sensor and light curtain. When the contact plate is extended, the contact plate’s protrusion is suitable for 30mm to 50mm, and the same amount of two contacts is used. The light curtain should be even, and no abnormal trigger should occur during the rapid opening and closing process, especially for the rear light curtain to keep clean.
  2. Adjust the opening knife: step 1: make sure the distance between the door knife and the floor sill of the hall door is 7mm, and ensure the vertical direction; Step 2: determine the distance between the blade of the door knife and the decoupling roller of the door lock of the hall door is about 7mm. Check running elevator to observe all the way, depends on the clearance of most hall door, can be in a small range on the left, right, right amount translation car door assembly (this method is not applicable to double synchronous door knife of double folding door such as TD3200 car elevator door machine); Step 3: the two surfaces of the door knife blade, namely the one of the rollers, must be vertical. Step 4: check that when driving the door, the blade should not make abnormal sound.
  3. The speed of opening and closing shall be adjusted when the door of the sedan chair drives the door of the hall. The speed shall be controlled at about.070m/s. The speed of opening and closing doors should be gentle according to the elevator’s different acceleration and deceleration.

What is the function of escalator apron board safety device?

The micro-switch of apron plate is a safety-protection micro-switch after the apron plate. When the escalator works normally, there is a certain gap between the apron board and the step. The single side is no more than 4mmand the sum of both sides is no more than 7mm. In order to guarantee the safety of the passengers, the apron board on the back of the pack of c-shaped steel, c-shaped steel distance setting switch, when foreign body into the apron board and the gaps between the cascade, apron plate deformation, c-shaped steel also move, after reaching a certain position, touch attack switch, then escalator stop running immediately.

The sensitivity of the device depends on the rigidity of the apron board. Too rigid apron plate is not easy to deform, cannot touch the micro switch, does not play a safe protection role; the rigidity is too small and the phenomenon of frequent parking will bring troubles to the normal operation of escalators. In addition, the micro switch is not generally set in the whole process, and it is only installed at the exit entrance of the escalator. Therefore, there are safety risks in the area other than the micro switch.

 

Filling device

A plastic and dry lubricant filled plate is arranged on both sides of the step and its shape matches the step. Fill plate by a spring or tie rod to keep its position and the entire range of the escalators and apron board contact, filled with escalators between apron board and cascade on both sides of the gap and its safety protective effect is obvious. The device, the filling plate contact with apron board is a kind of dry friction, easy to wear apron board Teflon coating and furnish the filler plate larger workload, so rarely used in our country.

Anti- clamping device

This is an economical and practical anti-clamping device, which compresses the rubber into a D section and fixes it to the apron board. Because the friction coefficient of rubber material is big, once the passenger meets the feeling that can be pulled again, can leave both ends of the step automatically, have safe protection effect.

For escalators with such clamping devices, rubber strips should not have sharp edges and should be checked frequently, as they can also bring danger to passengers if they leave apron boards.

Safety brush clamping device

Installed on the apron board safety brush, brush the clamp device is composed of base and brush, base without sharp edges, and can easily remove brush is soft and has a certain hardness, it does not hurt the clothing, meet the brush in the passengers’ shoes automatically after recovery.

The safety protection effect of safety brush anti-clamp device is obvious.
