A Circumferential Distributed Friction Lifting System for Ultra-Deep Shafts

Abstract

A circumferential distributed friction lifting system for an ultra-deep vertical shaft, the system includes friction wheels, left and right guide wheels, left and right lifting containers, balance ropes, tension adjustment systems, composite wheel sets, steel wire ropes, reels and wire rope buckles; each composite wheel The friction wheels are distributed in the circumferential direction, and the tension of each steel wire rope is adjusted by adjusting the position of the compound wheels in the compound wheel set. The invention helps to reduce the bending stress of the friction wheel shaft, overcomes the problem of excessive bending stress of the friction wheel shaft in the traditional friction lifting system; does not need to install the traditional container tension balance device, and effectively overcomes the tension caused by the displacement difference of different steel wire ropes The problem of unbalance and the increased self-weight of the traditional container tension balance device; at the same time, the position adjustment range of the composite wheel is large, which avoids the problem of the small adjustment range of the traditional hydraulic tension balance device connected to the container.

Description

technical field [0001] The invention relates to a hoisting system for an ultra-deep shaft, in particular to a circumferentially distributed friction hoisting system for an ultra-deep shaft. Background technique [0002] In the multi-rope friction hoisting of ultra-deep shafts, in the traditional friction hoisting system, each steel wire rope acts on the friction wheel with radial force in the same direction. If the load is too large, the bending stress of the friction wheel is often very large, threatening the life of the friction wheel and Improve system security. On the other hand, due to errors in the manufacturing and installation process of the steel wire rope and the partial load during the lifting process, the tension of the steel wire rope is often unbalanced, and the wear degree of each steel wire rope is different, which directly affects the service life of the steel wire rope. At present, the traditional container tension balance device is mostly used to adjust t...
