A high-voltage traction machine

Abstract

The invention provides a high-voltage traction machine and belongs to the technical field of machines. The high-voltage traction machine solves the technical problems that when a traction machine in an elevator in the prior art is used for lifting a lift car, no buffer device is available, and stationarity of ascending and descending of the lift car is poor. The high-voltage traction machine comprises a traction motor, a traction rope, a lift car and a traction wheel, and further comprises a platy connecting plate, the traction motor is fixedly connected with the connecting plate, the traction wheel is fixedly connected with a rotating shaft of the traction motor, the top of the lift car is fixedly connected with a first transition wheel, the two edges of the bottom of the lift car are fixedly connected with a second transition wheel and a third transition wheel, one end of the traction rope is fixedly connected with the connecting plate, the first transition wheel, the second transition wheel and the third transition wheel abut against the middle of the traction rope in sequence, the other end of the traction rope is connected with the traction wheel, and the upper portion of the connecting plate is fixedly connected with a high-voltage frequency converter connected with the traction motor. The high-voltage traction machine has the advantages of being smooth and steady in lifting and good in buffer effect.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a high-voltage traction machine. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. At present, the elevator traction device that drives the elevator car to move up and down is ...

AI Technical Summary

Problems solved by technology

[0004] Although the elevator disclosed in this patent can reduce the height of the top floor of the elevator shaft and save the space of the shaft, the traction machine in this elevator does not have a buffer device when lifting the car, and the stability of the car up and down is relatively poor.
