Trolley type fully-mechanized coal mining hydraulic support assembling frame

Abstract

A trolley type fully-mechanized coal mining hydraulic support assembling frame comprises four assembling unit frames and a trolley mechanism. Each assembling unit frame is provided with a platform trolley, wherein a trolley body rotating device is disposed in the middle of the platform trolley, a trolley body rotating hydraulic cylinder is disposed in the trolley body rotating device, an operation rail is disposed on the platform trolley, slideways are arranged on two sides of the platform trolley, sliders are disposed on the slideways, external square tube standing columns are hinged to the sliders, swing hydraulic cylinders are connected between the external square tube standing columns and the sliders, internal square tube standing columns are nested into the external square tube standing columns, standing column lifting hydraulic cylinders are disposed in the internal square tube standing columns, and lifting sliders are connected to the piston rods of the standing column lifting hydraulic cylinders. The trolley mechanism comprises a longitudinally-moving trolley, a longitudinally-moving traction device and a hoisting trolley. The trolley type fully-mechanized coal mining hydraulic support assembling frame has the advantages that heavy objects are hoisted by the hoisting hydraulic cylinder of the hoisting trolley, assembling or disassembling positions can be controlled optionally, flexible assembling and disassembling are achieved, large hoisting height is achieved, large assembling and disassembling space is achieved, and the assembling frame is applicable to assembling and disassembling of various types of hydraulic supports.

Description

technical field [0001] The invention relates to a device for installation and withdrawal of a complete set of fully mechanized mining equipment in a coal mine, in particular to a hydraulic support assembly frame for assembling and disassembling a hydraulic support. Background technique [0002] Fully mechanized mining hydraulic support is a kind of hydraulic power device that uses liquid pressure to generate support force and realizes automatic transfer for roof support and management. It is an indispensable supporting equipment for comprehensive mechanized coal mining. There are a large number of hydraulic supports in the complete set of equipment for fully mechanized mining in coal mines. Usually, the number of hydraulic supports is not less than one hundred. It is large and heavy, so the hydraulic support must be disassembled into several parts when it is transported underground in the coal mine, and then transported by a flatbed truck to the designated location for assem...

AI Technical Summary

Problems solved by technology

[0007] When assembling the hydraulic support of the above-mentioned fully mechanized mining hydraulic support assembly frame, there is insufficient strength of the square tube column, the positioning of the assembled parts is difficult when lifting, and the lifting parts cannot move longitudinally. Often, the assembly is slow due to the inappropriate placement of the hydraulic support base. And the lifting height of the parts is limited, which cannot meet the assembly and disassembly work of various types of hydraulic supports
