Abstract

The invention discloses a method for replacing a column of a hydraulic support, comprising: installing a hoisting device; opening a general control valve, and opening the control valves of each column except the column to be replaced; connecting the moving column of the column to be replaced with the hoisting equipment, disassembling Move the column and lift it away; close the main control valve, remove the pipe fittings and valves after pressure relief, and seal the corresponding nozzles and valve ports on the hydraulic support; connect the fixed base of the column to be replaced with the hoisting equipment, remove the fixed base and lift it away; Lift the fixed base of the column to be installed and fix it to the bottom plate of the hydraulic support; unseal the nozzle and valve port, install the pipe fittings and valves on the column to be installed; open the main control valve, and open each The control valve of the column drives the moving column of the column to be installed to extend to abut against the top plate of the hydraulic support, and fix the moving column and the top plate. The invention provides a method for replacing a column of a hydraulic support, which quickly disassembles and assembles the column of the hydraulic support, thereby improving replacement efficiency and operation safety.

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...
