A rope end relaxation device

Abstract

This utility model provides a rope end loosening device, including a counterweight rope suspension plate. Multiple rope end assemblies are mounted on the counterweight rope suspension plate. A safety switch trigger assembly seat is vertically welded to the surface of the counterweight rope suspension plate. One end of each rope end assembly is connected to a safety switch trigger assembly. A safety switch reinforcing plate is mounted on the safety switch trigger assembly. A safety switch is mounted on the safety switch reinforcing plate via bolt assembly two. The safety switch trigger assembly and the safety switch trigger assembly seat are fixedly connected via an extension plate. The extension plate is fixedly connected to the safety switch trigger assembly seat via bolt assembly one. This utility model uses the rope end assemblies to detect the tension of the traction steel wire rope, ensuring uniform force distribution on the elevator traction steel wire rope. The tension of different steel wire ropes is adjusted accordingly using the tightening bolt assembly three.

Description

Technical Field

[0001] This utility model belongs to the field of elevator components, specifically a rope loosening device. Background Technology

[0002] With the rapid development of elevator technology, more and more elevators are using steel belts instead of traditional steel wire ropes as traction ropes. As a result, various weighing devices for the ends of these steel belts have emerged. These devices calculate the load weight of the elevator car by detecting the tension of the steel belt. However, during elevator operation, the tension of each steel wire rope varies. Over time, this uneven tension causes wear on the traction sheaves, accelerating the deterioration of the elevator.

[0003] In summary, this utility model provides a rope end loosening device to solve the above-mentioned problems. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a rope end relaxation device to solve the problems of uneven force distribution on the wire rope in the prior art, which leads to wear on the traction sheave and exacerbates the deterioration of the elevator.

[0005] A rope end loosening device includes a counterweight rope suspension plate, on which multiple rope end assemblies are mounted. A safety switch trigger assembly seat is vertically welded to the surface of the counterweight rope suspension plate. One end of each rope end assembly is connected to a safety switch trigger assembly. A safety switch reinforcing plate is mounted on the safety switch trigger assembly. A safety switch is mounted on the safety switch reinforcing plate via a second bolt assembly. The safety switch trigger assembly and the safety switch trigger assembly seat are fixedly connected via an extension plate, which is fixedly connected to the safety switch trigger assembly seat via a first bolt assembly.

[0006] Furthermore, the rope end assembly is connected to the safety switch plate assembly via a bolt assembly.

[0007] Furthermore, the bolt assembly three and bolt assembly two have the same structure as bolt assembly one, each including a bolt, nut, washer and spring washer.

[0008] Furthermore, the bolt assembly two uses cross-head bolts.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses a rope head assembly to detect the tension of the traction steel wire rope, ensuring uniform force distribution on the elevator traction steel wire rope. The tension of different steel wire ropes can be adjusted accordingly using the three-part tightening bolt assembly. Attached Figure Description
