Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, and in particular relates to a protective device for elevator traction machines. Background Technology

[0002] The traction machine, also known as the elevator main unit, is the power equipment of an elevator. It consists of a motor, brake, coupling, gearbox, traction sheave, frame, guide wheels, and auxiliary handwheel, etc. Its function is to transmit and transfer power to make the elevator run. The motor rotates the traction sheave through the gearbox and other mechanisms. The wire rope runs in the groove of the traction sheave, thus moving the car up or down. However, after the wire rope has been running for a long time, the lubricating oil comes into contact with the dust on the surface of the wire rope, causing sludge to accumulate in the groove of the traction sheave. This affects the lubrication of the wire rope and may even shorten its lifespan. In the existing technology, to prevent sludge from accumulating in the groove of the traction sheave, roller brushes or bristles are installed on the traction machine mounting base. However, the roller brushes or bristles wear down due to prolonged friction with the wire rope, and the ability to clean dust from the wire rope surface is greatly reduced after wear.

[0006] Furthermore, it also includes a protective cover, which is mounted on the support frame, and there is a gap between the inner wall of the protective cover and the traction sheave, the support base and the wire rope.

[0007] Furthermore, the jet assembly also includes an air compressor; the air compressor is mounted on a support frame and located on one side of the motor; one end of the jet main pipe is connected to the air compressor pipeline.

[0008] Furthermore, the jet pipes are disposed on both sides of the wire rope, with one nozzle on each side of each wire rope.
