Impact friction test system for winding hoisting rope of kilometer deep shaft

Abstract

The invention discloses an impact friction test system for a winding hoisting rope of a kilometer deep shaft. The system comprises a rack, wherein a roller is arranged at the left end of the rack; the roller is erected in a bearing seat on the rack through a roller center shaft; the roller center shaft is connected with a variable-speed motor through a torque rotational speed meter; a thrust oil cylinder is horizontally arranged at the right end of the rack and is arranged on the same height position as the roller center shaft; the thrust oil cylinder is connected with a friction wheel through a hinge pin; the centroid of the friction wheel is at the same height as the position of the thrust oil cylinder; the two sides of the friction wheel are fixed on a movable support; the movable support is erected on a guide rail of the rack; and the wire rope is wound on the roller by two circles in parallel and is wound on the friction wheel by one circle. The system can be used for simulating the working condition of impact friction of the winding hoisting rope of the kilometer deep shaft, so that the tribological property of the wire rope in the conditions of different rotational speeds, accelerations, impact speeds and specific contact pressures can be studied. The system disclosed by the invention has the advantages of simple and compact structure, simple method, relatively low cost and outstanding effect.

AI Technical Summary

Benefits of technology

This patented technology allows researchers to study how long an elevator cable works when it goes up or down inside a large bore hole underground without getting stuck due to excessive wear on its surface caused by repeated use over time. It simplifies the structure of the system while still providing accurate data about the workings being done. Additionally, this technology helps predict future failures that may occur during operation based upon these results.

Problems solved by technology

The technical problem addressed by this patented technology relates to developing an effective testing method for studying how severe damage occurs when wires used on mineral lifting equipment come into contact with other materials such as steel plating or concrete slabs under heavy loadings.
