Compensation chain production correcting unit

Technical Field

The utility model relates to an auxiliary device technical field of elevator compensation chain production especially relates to a compensation chain production correcting unit that one type of iron chain wraps up in outside and covers PVC.

Background

In the running process of the elevator, the lengths of the steel wire ropes on the car side and the counterweight side are continuously changed, so that the weight of the steel wire ropes on the two sides of the traction sheave is changed. Such a change can seriously affect the stability of the elevator operation when the elevator is lifted above a certain height (30 m in the industry), endangering the safety of passengers. For this purpose, components with a certain weight have to be provided to compensate for the weight change due to the height change, which is the elevator compensating chain. The compensation chain is required to be straight and cannot have torsional force, otherwise, the vibration of the car can be caused due to the swinging of the compensation chain, and the iron chain wrapped in the PVC is required to be not twisted and screwed during production, so that the high linearity is ensured. The existing production process mostly adopts manual drag and drop breaking of an iron chain before PVC extrusion to prevent distortion and spiral, and has low production efficiency, higher labor cost and insufficient quality control.
