What are the components of the elevator?

Elevator is a large-scale complex product with mechanical and electrical integration. The mechanical part is equivalent to the human body, and the electrical part is equivalent to the human nerve. The high integration of mechatronics makes the elevator a comprehensive product of modern science and technology. For the elevator structure, the traditional method is divided into mechanical part and electrical part, but the functional system can better reflect the characteristics of the elevator. Let's briefly introduce the structure of the elevator mechanical part, and our main purpose is how to control it.

I. Traction system

The main function of the traction system is to output and transmit power to make the elevator run.

The traction system is mainly composed of traction wire rope, guide pulley and anti-rope pulley.

Two. guidance system

The main function of the guide system is to limit the freedom of movement of the car and counterweight, so that the car and counterweight can only move up and down along the guide rail.

The guide system is mainly composed of guide rail, guide shoe and guide rail frame.

Three. automobile

The car is an elevator component for transporting passengers and goods, and it is the working part of the elevator.

A car consists of a frame and a body.

Four. Door system

The main function of door system is to close the entrance of landing and car.

The door system consists of car door, landing door, door opener and door lock device.

Verb (abbreviation for verb) weight balance system

The main function of the system is to relatively balance the weight of the car, keep the weight difference between the car and the counterweight within a limited range, and ensure the normal traction drive of the elevator.

The system is mainly composed of counterweight and weight compensation device.

Electric drive system of intransitive verbs

The function of electric drive system is to provide power and realize elevator speed control.

The electric drive system consists of traction motor, power supply system, speed feedback device and motor speed regulating device.

Seven. electrical control system

The main function of the electric control system is to manipulate and control the operation of the elevator.

The electrical control system is mainly composed of control device, position display device, control panel (cabinet), leveling device and layer selector.

Eight. Safety protection system

Ensure the safe use of elevators and prevent all accidents that endanger personal safety.

It consists of speed limiter, safety clamp, buffer and terminal protection device.
