A hydraulic support cylinder column removal device

Abstract

The invention discloses a device for detaching a column of an oil cylinder of a hydraulic bracket. The device comprises a bottom plate and a motor. Two parallel guide rails are fixed to the bottom plate, a hydraulic bracket transport cart and an oil cylinder column transport cart are separately mounted at two ends of the guide rail, a motor is also mounted on the bottom plate, a lead screw is fixed to the output end of the motor, the lead screw is in threaded connection to the bottom end of the connecting plate, a portal frame is fixed to the middle of the bottom plate through a bolt, a lifting hydraulic cylinder is mounted on the top of the portal frame, and a supporting plate is fixed to the telescopic end of the lifting hydraulic cylinder through a bolt. The device drives the hydraulicbracket transport cart by means of a lead screw transmission principle to transport the hydraulic bracket to the supporting plate to support a supporting arm of the hydraulic bracket, so that the riskthat the hydraulic bracket collapses as the supporting force is not available is avoided. The oil cylinder column is fixed and transported through the oil cylinder column transport cart, so that thesafety of staff is guaranteed, the work strength is reduced, and the detaching efficiency of the column of the oil cylinder of the hydraulic bracket is improved favorably.

Description

technical field [0001] The invention belongs to the technical field of hydraulic support maintenance devices, and in particular relates to a hydraulic support cylinder post removal device. Background technique [0002] Hydraulic support is an important part of comprehensive coal mining equipment. It can reliably and effectively support and control the roof of the working face, isolate the goaf, and prevent gangue from entering the mining face and pushing the conveyor. In the process of coal mining, it is necessary to select different types of hydraulic supports according to the specific conditions of the coal mining face in the coal mine, so as to make better use of resources and improve coal mining efficiency. [0003] When disassembling and overhauling the oil cylinder column of the hydraulic support, the existing practice is to disassemble the oil cylinder column after the top structure of the hydraulic support is removed. The operation is complicated and the work intens...

Problems solved by technology

[0003] When disassembling and overhauling the oil cylinder column of the hydraulic support, the existing practice is to disassemble the oil cylinder column after the top structure of the hydraulic support is removed. The operation is complicated and the work intensity is high. Moreover, the oil cylinder column cannot be supported and After subsequent transportation, the column is prone to tilt, which poses a safety risk, and it is difficult to adapt to the disassembly and maintenance operations of a large number of hydraulic support cylinder columns
