Friction test device for steel wire rope

Abstract

The invention relates to a friction test device for a steel wire rope. The steel wire rope includes a center steel wire and an outer steel strand arranged around the steel wire. The friction test device comprises a fixed rack and a test assembly arranged on the fixed rack, the fixed rack is provided with a saddle connected to the steel wire rope, and the test assembly is provided with a tension meter. The friction test device for the steel wire rope provided by the invention can test the friction coefficient and slip characteristics of the steel wire rope and the saddle, reduce the floor space and use cost of the test device, and improve the similarity of test data and actually used data.

Description

technical field [0001] The invention relates to a test device, in particular to a friction test device for steel wire ropes. Background technique [0002] As an important part of the power transmission line freight ropeway, the steel wire rope plays a vital role in the operation safety of the power transmission line freight ropeway. The friction and slippage between the steel wire rope and the saddle of the freight cableway cause safety hazards to the operation of the freight cableway, and even endanger the overall progress of the project. Therefore, it is necessary to provide a test device for steel wire ropes to measure the friction coefficient and slip characteristics between the steel wire rope and the saddle, and to ensure the safety and stability of the freight cableway for power transmission lines. [0003] The existing steel wire rope test method is to anchor one end of the steel wire rope, and the other end uses a plurality of jacks to synchronously stretch the ste...

AI Technical Summary

Problems solved by technology

[0003] The existing steel wire rope test method is to anchor one end of the steel wire rope, and use multiple jacks to simultaneously stretch the steel wire rope strands at the other end. This method has the following disadvantages: ①The equipment occupies a large area, is expensive, and is not easy to popularize and use

② Poor structural stability, unable to withstand sufficient test load

③Complicated installation and disassembly, high requirements for workers

④The scope of application is narrow, it can only be used for saddles of a single material and wire ropes of the same specification

⑤ Unable to fully simulate the actual working conditions where the tension at one end is controllable and movable, the test efficiency is low, and the deviation between the test data and the actual data is large

⑥ The envelope angle between the wire rope and the saddle cannot be adjusted, and the deviation between the test data and the actual use data is large

⑦ Complex production, high production and use costs
