Description

Technical Field

[0001] The utility model relates to the technical field related to elevator accessories, and in particular to an elevator compensation chain installation protection structure. Background Art

[0002] The compensating chain is a component used to compensate for the weight imbalance between the car and the counterweight caused by the traction rope during elevator operation. Its main function is to balance the changes caused by changes in the wire rope and accompanying cable during elevator operation.

[0003] After extensive searching, I discovered Chinese patent publication number CN206827885U, which discloses a counterweight compensation chain frame. This patent relates to the field of elevator technology. The patent provides a compensation wheel guide rail bracket, including a counterweight mechanism and a compensation chain connected to the bottom of the counterweight mechanism. The patent is characterized in that a counterweight compensation chain frame body is mounted on the bottom of the counterweight mechanism and connected to the compensation chain. The counterweight compensation chain frame body includes a counterweight block seat, a compensation chain fixing seat, and a compensation chain buffer structure disposed between the counterweight block seat and the compensation chain fixing seat. This patent converts the potential energy generated by the compensation chain into elastic potential energy of the compensation chain buffer structure, preventing it from being converted into kinetic energy of the compensation chain itself.

[0004] In summary, with the demand for elevators with large lifting heights, the length of elevator wire ropes is getting longer and longer, and the weight of the compensation chain will also increase accordingly. The existing compensation chain installation structure cannot effectively eliminate problems such as wear and deformation that occur during normal operation.

[0005] In view of the above-mentioned defects, the designer has actively carried out research and innovation in order to create an elevator compensation chain installation protection structure to make it more valuable for industrial use. Utility Model Content
