Description

Technical Field

[0001] The invention relates to the technical field of elevator equipment, in particular to a rust removal device for elevator guide rails. Background Art

[0002] When the elevator is equipped with sliding guide shoes, in order to reduce the friction of the guide shoes, an oil cup is installed on the guide shoes. The oil cup stores lubricating oil and lubricates the guide rails at any time. While lubricating the guide rails, the guide rail working surface is also isolated from the air under the protection of the lubricating oil, which plays a role in rust prevention of the guide rails. For elevators equipped with roller guide shoes, the guide shoe rollers are made of nylon and rubber. If the guide rails are also rust-proofed with lubricating oil, the rollers are soaked in lubricating oil for a long time, and the lubricating oil will corrode the roller nylon and rubber. Therefore, the guide rails equipped with roller guide shoes have the working surface of the guide rails directly exposed to the air for a long time, and the working surface of the guide rails will rust. The rust powder sticks to the guide rails, which may affect the comfort of elevator operation and the performance of the safety clamp. At present, manual rust removal is usually used for elevator guide rails, which has low rust removal efficiency, affects the normal operation of the elevator, and the safety of manual operation inside the elevator shaft is low.
