Description

Technical Field

[0001] The invention relates to a suspension device, in particular to a suspension device for an elevator compensation cable, and belongs to the technical field of elevator safety. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. During the operation of the elevator, the length of the wire ropes on the car side and the counterweight side is constantly changing, which causes the weight of the wire ropes on both sides of the traction wheel to change. When the car is at the lowest floor station, most of the weight of the wire rope acts on the car side; when the car is at the highest floor station, most of the weight of the wire rope acts on the counterweight side. This change has little effect on the operating performance of the elevator when the elevator lifting height is not large, but when the lifting height exceeds a certain height, it will seriously affect the stability of the elevator operation and endanger the safety of passengers. For this reason, when the elevator lifting height exceeds a certain height, an elevator balance compensation chain with a certain weight must be set to balance the weight change caused by the height change.

[0003] The two ends of the existing elevator balance compensation chain are respectively installed at the lower ends of the elevator car and the elevator counterweight device. However, since the elevator car and the counterweight device are heavy, the elevator balance compensation chain will be pulled during the operation of the elevator. After long-term pulling, the connection between the elevator balance compensation chain and the counterweight device or the elevator car may become loose, which will cause the compensation chain to shake violently during operation, thereby driving the elevator car to shake, affecting the operation of the elevator. Summary of the invention
