Description

Technical Field

[0001] This utility model belongs to the technical field of passenger elevator traction devices, specifically relating to a traction-type passenger elevator traction device. Background Technology

[0002] A traction machine is an essential component of traction passenger elevators. Traction elevators utilize the friction between the traction sheave and the wire rope to achieve relative movement between the car and the counterweight. A motor drives the traction sheave to rotate, and the wire rope is wound around it, with one end connected to the car and the other to the counterweight. As the traction sheave rotates, friction drives the wire rope, thereby raising or lowering the car.

[0003] The stable connection between the traction sheave and the wire rope on the traction machine is crucial for the normal and safe operation of passenger elevators. Therefore, personnel often need to maintain the traction sheave and wire rope. Common methods include lubrication and dust removal. However, maintenance is often done manually, which is not only time-consuming and labor-intensive but also inconvenient for high-frequency maintenance. Therefore, a new type of traction machine needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a traction device for a traction elevator to solve the problem of inconvenient maintenance of the traction wheel and wire rope on the traction machine mentioned in the background art.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The designed lubrication components lubricate the traction sheave and the wire rope wound around it. The hydraulic rod periodically pushes the base box down, allowing the brush to contact the traction sheave. The lubricating oil inside the base box is applied to the traction sheave and wire rope through the brush, thus providing lubrication. When the traction sheave rotates, the cleaning brush on the cleaning component continuously cleans the surface of the traction sheave and wire rope, thus removing dust. Through the cooperation of the above structures, the maintenance of the traction machine can be completed automatically without manual operation, saving time and effort. Attached Figure Description
