Modification method of a multi-rope friction hoist

Abstract

The invention discloses a multi-rope friction type hoister transformation method. Specifically, the multi-rope friction type hoister transformation method comprises the steps that a main shaft deviceof an original multi-rope friction type hoister is replaced, and a new main shaft device is redesigned and manufactured according to a novel direct connection cantilever structure; a low-speed directcurrent motor is adopted to be in direct connection transmission with the new main shaft device; an inblock cast disc-shaped brake of the original multi-rope friction type hoister is converted into anormally closed type rear oil cylinder disc-shaped brake; and a KT coil gate adjusting hydraulic station of the original multi-rope friction type hoister is replaced with a proportional electromagnetic valve gate adjusting hydraulic station of the normally closed type rear oil cylinder disc-shaped brake. According to the multi-rope friction type hoister transformation method, an original speed reducer, a gear coupling and an elastic bar pin coupling are removed, corresponding equipment used for lubricating the speed reducer is removed, the intermediate transmission procedure is omitted, the fault probability of a hoister and the manufacturing and installing cost of the equipment are reduced, and the maintenance workload of a user is decreased.

Description

technical field [0001] The invention belongs to the technical field of mine hoists, in particular to a method for transforming a multi-rope friction hoist. Background technique [0002] Mine hoist is one of the important and key equipment in mines. It is mainly used in coal mines, metal mines and non-metal mines to lift and lower personnel, lift coal, ore, and transport materials and equipment. It is an important means of transportation connecting the mine and the mine, and occupies a very important position in the mine, known as the "throat equipment" of the mine. With the continuous improvement and development of the technical level of mine hoisting equipment, many hoists with long service life, especially supporting single output shaft double input shaft gear reducer, gear coupling, elastic pin coupling, double high speed motor The traditional multi-rope friction hoist with outdated, backward, and low-efficiency transmission has become more and more backward in technical...

Problems solved by technology

With the continuous improvement and development of the technical level of mine hoisting equipment, many hoists with long service life, especially supporting single output shaft double input shaft gear reducer, gear coupling, elastic pin coupling, double high speed motor The traditional multi-rope friction hoist with outdated, backward, and low-efficiency transmission has become more and more backward in technical level, with small output, high energy consumption, and large maintenance. Moreover, the unsafe factors of the equipment have brought many problems to production. hidden dangers, seriously threatening safe production

There are two ways to solve these problems. One is to update the equipment, which requires a large investment and a long replacement time; the other is to carry out technical transformation of the old equipment according to the specific conditions of each mine and the future use requirements. On the premise of meeting the technical requirements , try to adopt new technologies, new achievements, and new structures to improve the accuracy of equipment, save energy, reduce energy consumption, reduce costs, improve equipment safety and reliability, and achieve the purpose of improving equipment design levels. However, due to the traditional The structure of the multi-rope friction hoist is complicated, and the field use environment is complicated. At present, there is no good transformation method to upgrade the traditional multi-rope friction hoist.
