Everyone knows about elevators, and they are relatively common. Few people know the five major pieces of elevators, which are relatively new to everyone. The five major pieces refer to traction machines, control cabinets, speed limiters, and car door machines. Safety gear. Then I will explain it to you in detail below. What are the five major pieces of elevators? Do you know?
Elevator traction machine is the power equipment of the elevator, also known as the elevator host. Its function is to transmit and transfer power to make the elevator run. It consists of motor, brake, coupling, reducer, traction wheel, frame and guide wheel, auxiliary disk drive wheel, etc. The guide wheel is usually mounted on the frame or a load-bearing beam under the frame.
The control cabinet assembles switchgear, measuring instruments, protective devices and auxiliary equipment in closed or semi-closed metal cabinets or screens according to the requirements of the wires. The layout should meet the requirements for normal operation of the power system, be easy to maintain, and not endanger personal safety. And surrounding equipment. In normal operation, the circuit can be opened or closed by manual or automatic switches.
3. Weight balance system
The main function of the system is to balance the weight of the car. During elevator operation, the weight difference between the car and the weight can be kept within limits, and the traction drive of the elevator is normal. This system is mainly composed of counterweight and counterweight compensation device.
Elevator door crane is a mechanism responsible for opening and closing the elevator hall door. When receiving the opening and closing signals of the elevator, the elevator door machine controls the opening motor through its own control system, and converts the torque generated by the motor to a specific direction. Close or open the door firmly.
5. Security protection system
Ensure the safe use of the elevator and prevent all accidents that endanger personal safety. 。 Including elevator speed limiter, safety clip, rope clamp device, buffer, safety contact plate, floor door lock, elevator safety window, elevator overload limit device and limit switch device .
What are the five major pieces of the elevator above ? Do you know what we know here? The five components refer to the traction machine; control cabinet; speed limiter; car door machine; safety gear. The main unit only has the controller, inverter vehicle and counterweight, wire rope and guide rail, safety gear speed limiter and buffer.
