Hydraulic bracket upright column replacement method

Abstract

The invention discloses a hydraulic bracket upright column replacement method which comprises the following steps: mounting hoisting equipment, opening a main control valve, opening control valves ofdifferent upright columns except an upright column to be replaced, connecting a moving column of the upright column to be replaced with the hoisting equipment, and disassembling and hoisting off the moving column; closing the main control valve, releasing the pressure, disassembling tubes and valves, and sealing corresponding tube openings and valve openings on a hydraulic bracket; connecting thefixing base of the upright column to be replaced with the hoisting equipment, and disassembling and hoisting off the fixing base; hoisting and fixing the fixing base of the upright column to be mounted with the bottom plate of the hydraulic bracket; unsealing the tube openings and the valve openings, and mounting the tubes and the valves on an upright column to be mounted; opening the main controlvalve, opening control valves of different upright columns including the upright column to be mounted, driving the moving column of the upright column to be mounted to extend and prop against the topplate of the hydraulic bracket, and fixing the moving column with the top plate. The invention provides the hydraulic bracket upright column replacement method, upright columns of hydraulic bracketscan be rapidly assembled and disassembled, and the replacement efficiency and the operation security can be improved.

Description

technical field [0001] The invention relates to mining equipment for a fully mechanized mining face, and more specifically, to a method for replacing a hydraulic support column. Background technique [0002] Hydraulic support is an important part of mining equipment in fully mechanized mining face. Hydraulic support is widely used in roadway advance support. It has the advantages of high support strength, high degree of automation, fast operation speed and high safety. It is suitable for large section, Roadways with broken and severely deformed surrounding rocks and high-yield working faces with large mining height, high degree of mechanization, and fast advancing speed. [0003] As the main bearing mechanism of the advanced hydraulic support, the performance of the column directly affects the quality of the support and determines the safety of roadway construction and mining efficiency. Affected by manufacturing materials, technological level, downhole operating environmen...

AI Technical Summary

Problems solved by technology

Due to the lack of a unified operation process and operation standards, it is difficult to guarantee the operation quality of replacing the column, resulting in slow operation, or even replacement failure, affecting operation efficiency; at the same time, it may also cause personnel safety problems and affect operation safety
