Non-stop Renovation Method of Multi-rope Friction Wheel Hoisting Blind Shaft Hoisting System

Abstract

The invention discloses a non-production-stopping modifying method for a hoisting system with a multi-rope friction pulley for hoisting an internal shaft. A new hoisting system hoister chamber (15) is newly excavated in the opposite face or the side face of an original hoister chamber (14), a new hoisting system rope channel (6) is newly excavated 4 m-8 m above the top end of the internal shaft (1) from the new hoisting system hoister chamber (15), and a new hoisting system hoisting sheave chamber (16) is excavated in the end of the new hoisting system rope channel (6); a new hoisting system steel wire rope hole (8) is drilled downwards in a bottom plate rock pillar of the new hoisting system hoisting sheave chamber (16) through a jackdrill, a steel wire rope is connected with a hoisting container (13) through the new hoisting system rope channel (6), a new hoisting system hoisting sheave (7) and the new hoisting system steel wire rope hole (8), and usage of an original hoister is stopped. The new hoisting system is excavated and installed in a position different from that of a hoisting system in use, the new hoisting system and the hoisting system in use do not affect each other, and therefore the hoisting system with the multi-rope friction pulley for hoisting the internal shaft is modified in a non-production-stopping mode.

Description

technical field [0001] The present invention relates to a transformation method of an underground multi-rope friction wheel blind shaft hoisting system, in particular to a transformation method in which a blind shaft needs to replace hoisting equipment but cannot stop production for a long time, and can be used in steel, nonferrous metals, gold, chemical industry, coal Flexible application in underground mines. Background technique [0002] Blind shaft hoisting is widely used in underground mines in steel, non-ferrous metals, gold, chemical industry, coal and other industries, among which multi-rope friction wheel hoisting can be divided into tower type and floor type hoisting. [0003] In our country, there are many mines that adopt multi-rope friction wheel hoisting. Because the hoist originally selected is too small, the original hoist can no longer meet the safety requirements after the shaft is extended; in some mines, due to the small lifting capacity of the original d...

Problems solved by technology

[0005] The purpose of the present invention is to propose a multi-rope friction wheel blind hoisting system for the current blind shaft hoisting system in order to solve the problem that the original hoisting equipment is too small due to the extension of the shaft and the hoist needs to be replaced in order to increase the hoisting capacity, but the production cannot be stopped for a long time.
