Endless rope winch rope traction drive test system and method

Abstract

The invention discloses a rope pulling driving test system and method for an endless rope winch, and is suitable for a mining equipment simulation test. The system comprises a working platform, wherein the working platform is fixedly provided with a shock excitation cylinder through a shock excitation bracket; the working platform is fixedly provided with a tensioning oil cylinder through a tensioning oil cylinder bracket; the working platform is independently provided with a pulling winch and a loading winch; the shock excitation cylinder is connected with one side of the tensioning oil cylinder through a shock excitation cylinder and tensioning cylinder center alignment connection device; through the shock excitation cylinder, high-frequency vibration is applied to the tensioning oil cylinder; the other side of the tensioning oil cylinder is connected with the pulling winch through a hydraulic rod; the pulling winch is provided with a friction wheel a; the loading winch is provided with a friction wheel b; and a steel wire rope which is used as a transmission link is arranged between the friction wheel a and the friction wheel b. By use of the system, the revolving speed of the winch, the tension of the steel wire rope and the displacement of the tensioning cylinder can be detected so as to be favorable for deeply researching the friction characteristics of the endless rope. The system has the advantages of simple structure and good detection effect.

Description

technical field [0001] The invention relates to a test system and method, and is especially suitable for an endless rope winch rope traction drive test system and method used in mine equipment simulation tests. Background technique [0002] The stepless rope winch is a mine rail auxiliary transportation equipment pulled by steel wire ropes, which can well adapt to complex underground environments such as long distances, multiple turns, and large tonnages, so it serves the vast majority of coal mining areas in my country. Under the coal mine, the endless rope winch is used for transportation in the roadway and the fully mechanized mining face. It can transport the production materials and hydraulic supports and other equipment required by the fully mechanized mining face, which greatly improves the efficiency of underground transportation and is a safety university for coal mining enterprises. Production creates the conditions. However, there are some disadvantages in the en...

AI Technical Summary

Problems solved by technology

However, there are some shortcomings in the endless rope winch, such as: the steel wire rope is prone to slipping on the friction drum, which may cause failure if it is light, and cause a safety accident if it is serious; in the environment of high-frequency vibration underground, the tensioning device cannot work effectively; and , the working environment of the endless rope winch is harsh, and it is very difficult to conduct experimental research underground
