A non-stop transformation method for tower-type open-shaft hoisting to floor-type hoisting

Abstract

The invention discloses a non-stop production reformation method for reforming tower-type open vertical shaft lifting into floor type lifting. During the normal production period of an open vertical shaft needing to be reformed, a new shaft tower frame (9) is constructed on the periphery of an original shaft tower (1), after the height of the new shaft tower frame (9) exceeds the height of the top of the original shaft tower (1), the new shaft tower frame (9) continues to be constructed upwards till three layers of frame beams, that is, a lower head sheave platform beam (10'), an upper head sheave platform beam (10) and a head sheave overhauling lifting beam (11) which are needed by floor type lifting are formed on the upper surface of the new shaft tower frame (9); a new floor type lifting machine house (12) is built; a new lifting machine (2') is installed in the new floor type lifting machine house (12), and a new electric control system (4') is installed on one side of the new floor type lifting machine house (12); and an inclined cutting opening (13) and a vertical cutting opening (13') are formed to be used as channels of new lifting system steel wire ropes (14). According to the non-stop production reformation method for reforming tower-type open vertical shaft lifting into floor type lifting, a multi-rope friction wheel lifting machine of an open vertical shaft conducting normal production can be replaced under the non-stop production condition of the open vertical shaft, and thus upgrading and reforming can be conducted on the lifting system.

Description

technical field [0001] The present invention relates to a method for transforming a shaft hoisting system, in particular to a method for transforming a tower type open shaft hoist into a ground type hoist, which can be used in tower type open shaft hoisting systems in underground mines such as iron and steel, nonferrous metals, gold, chemicals, coal, etc. Applied in non-stop production transformation. 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, With the dev...

Problems solved by technology

[0005] The purpose of the present invention is to provide a tower type open shaft hoisting system for the problems 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 of the current tower type open shaft hoisting system, but the production cannot be stopped for a long time.
