A non-stop reconstruction method for a tower-type open shaft hoisting system

Abstract

The invention discloses a non-stop production reconstruction method for a tower-type external shaft hoisting system. The method comprises the steps that a new shaft tower framework (9) is constructed on the periphery of an original shaft tower (1), the upper portion, exceeding the tower top of the original shaft tower (1), of the new shaft tower framework (9) is reconstructed to be a closed new shaft tower upper framework body (1'), and a new guide wheel support platform (19) and a new hoister support platform (20) are constructed in the new shaft tower upper framework body (1') from bottom to top; a new traveling crane (8'), a new hoister (2'), a new electronic control system (4') and a new guide wheel (3') are installed and adjusted; an original hoister (2) and an original guide wheel (3) are removed or moved in maintenance or holiday time, steel wire ropes (15) of the new hoister (2') are connected with a hoisting container (5), in this way, renovation and reconstruction of the hoisting system are completed, and using of the original hoister (2) is stopped. According to the non-stop production reformation method for the tower-type external shaft hoisting system, an external shaft multi-rope friction wheel hoister used in normal production can be replaced on the condition that non-stop production of the external shaft is achieved, upgrading and reconstruction are conducted on the hoisting system, and the economic effect is obvious.

Description

technical field [0001] The present invention relates to a method for transforming an open shaft hoisting system, in particular to a method for transforming a tower type open shaft hoisting system, which can be used for non-stop production transformation of the tower type open shaft hoisting system in underground mines such as iron and steel, nonferrous metals, gold, chemical industry, coal, etc. in the application. Background technique [0002] Open shaft hoisting is widely used in underground mines in steel, non-ferrous metals, gold, chemical, coal and other industries. Among them, 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 design,...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to propose a tower type open shaft for the current tower type open 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 lifting capacity, but it cannot be shut down for a long time Improvement method for non-stop production of lifting system
