What are the general terms of the elevator components?

Elevator is a large and complex mechanical and electrical products, the elevator component is equivalent to the body of the body, the elevator part of the human body is equivalent to the nerve. The height of the machine and electricity, so that the elevator has become a modern science and technology products. Now the main components of the elevator are examples:

1, traction unit

The traction unit is lift lifting mechanism is arranged on a special bearing beam, mainly composed of motor, reducer (without this device machineroomless traction machine), brake, traction wheel, a guide wheel, a base, a damping device and a traction rope.

2, speed limiter

The speed limiting device is a safety device, which is connected with the car through a safety rope, and the movement of the car is transmitted to the speed limiter to rotate. When the car running speed is greater than the allowable speed, the speed limiter on the electrical switch action, first cut off the control system safety circuit, so that the elevator emergency stop. If it is also speeding the mechanical action, through the wire rope to drive the safety clamp action. To stop the car.

3, control cabinet

The control cabinet is the control center of the elevator, a variety of electronic devices and electrical components are installed in a closed metal containers, according to the reservation program control of car running.

4, elevator guide

The guide is for car and counterweight assembly plays a guiding role in the lifting operation, they are specified in the guide rail bracket pressure. When the safety clamping action is played, the guide rail is supported by the car and the load or the effect of the weight.

5, the weight of the device

The device is composed of a traction rope by the traction wheel is connected with the car, in the process of operation, and 40%~50% rated lift weight balance car load. The upper and the lower sides of the upper and the lower sides are provided with guide boots to ensure that the weight of the pair is sliding along the top and bottom of the heavy guide rail.

6, buffer

The buffer is arranged in the bottom hole, and when the car exceeds the upper or lower limit position, the braking safety device is used to buffer the energy consumption of the kinetic energy generated by the heavy device or the car.

7, forced deceleration switch, limit switch, anti - impact switch and limit switch

The upper and the lower end of the well path are respectively provided with three switches, which are forced deceleration switch, terminal limit switch and limit switch. When the car is running to the upper station or lower station in the deceleration position, hit the bow on car should first meet forcing deceleration switch, such as the elevator did not slow down, the switch will be forced into the elevator deceleration state, if the car offside (more than one floor. After a certain distance), hit the bow hit the limit switch cam, normally closed contact switch off, cut off the direction of signal, so that the elevator stops, cannot lift upward (in the upper station can only be down) or not, (or in the end can only downlink uplink). If the upper end of the station and then up (or in the lower end of the station), the limit switch will open the normally closed contact, forced to cut off the main circuit and control power supply. Limit switch is a non automatic reset safety switch device, so that the elevator can not up, can not be down, can only wait for the operator to move the car to the position, the elevator can be reset operation.

8, layer door

The door is a closed door that is set at the entrance of each layer. Each layer are arranged inside the door lock device, the door closed, the door locked, and connected to the control loop, the car can run. When any of the doors are opened, the control circuit will be disconnected and the elevator will not run to ensure safety.

9, call box

Call boxes at each layer of the layer by the door, the door and be made one call box layer indicator. It is able to show the passenger car running direction and layer station, but also for the passenger call ladder. In addition to the upper and lower end of the station for a single button, and the rest of the station are up and down two buttons. The call box of the base station is also provided with a key for the operator to switch the elevator at the base station.

10, car

The car is used for elevator components of passengers, it is fixed on the car frame, suspension traction rope, mounted on the car frame through four guide boots on both sides of the car guide rail along the vertical lifting operation. An automatic car door is arranged on the car entrance, and an interlocking switch is arranged on the door. Open the door directly to the car door, and the door is the door of the door on the door of the door when the door to reach the door lock, unlock the door lock, unlock the power, and the car and the door open or closed at the same time. It is only when the door is closed reliably to allow the lift to start. Once the door is opened, the running car will immediately stop running.

11, safety clamp

Safety is one of the important safety component of the elevator, it is mounted on the car frame on both sides of the beam. Safety clamp and speed limiting device are both composed of an elevator to prevent over speed and fall prevention safety device. When the elevator car speeding down, the speed limiter in the computer room will move to clamp the speed limiter wire rope. Thereby, the safety clamp operating mechanism is pulled, and the safety pliers on both sides of the clamp block are clamped on the guide rail to stop the car on the track. And action in the safety gear operating mechanism at the same time, safety switch action, open the control circuit, the elevator traction motor and brake power.

12, control box

Control box is an important part of the operation of the elevator driver (passengers). It is installed in the car, the side of the door. Above is a command button, open the door button, the driver can pass these buttons to make the elevator work.

13, leveling device

Flat stop layer device is installed near the car side, installed in the hoistway on each floor of the floor area of the induction magnetic isolation plate trigger, provide peace layer door zone signal control system, and also provide reference data for each floor position control system.
