A mining hydraulic support assembly platform

Abstract

The invention relates to a mining hydraulic support assembly platform which mainly comprises fork-type elevating platforms and cantilever type lifting platforms. The mining hydraulic support assembly platform is powered by hydraulic force to realize lifting and horizontal moving of the fork-type elevating platforms and lifting and telescopic movement of cantilever type lifting platforms. A hydraulic support is disassembled into a top beam assembly, a shield beam assembly and a pedestal assembly in a ground workshop and then transported to shaft bottom. During assembly of the hydraulic support, the assembly platform is placed in an air-return way of a working face, the assembly platform completely joint the hinge holes of the top beam assembly and the shield beam assembly and the hinge holes of the shield beam assembly and the pedestal assembly, hinge pins are inserted, and a rubber tube and other accessories are installed at last to complete assembly of hydraulic support. The disassembly of the hydraulic support is completed in a reverse order. The mining hydraulic support assembly platform is low in requirement on tunnel section, small in driving engineering work load, safe and efficient in installation, convenient for transportation and maintenance and low in cost. The platform can be used for installing and dismounting other fully mechanized mining equipment.

Description

technical field [0001] The invention relates to the field of mining machinery manufacturing and application, in particular to a mining hydraulic support assembly platform for installing and disassembling fully mechanized mining equipment such as mining hydraulic support. Background technique [0002] At present, due to the large size of the hydraulic supports of fully mechanized mining equipment in coal mines, the light ones are 30 to 40 tons, and the heavy ones are 50 to 60 tons. Due to the limitations of the lifting capacity of the coal mine and the conditions of the roadway, it is impossible to go down the mine as a whole. The hydraulic supports must be broken down into parts and transported down the mine separately. . [0003] At present, most domestic mines use electric hoist or manual hoist to lift and assemble hydraulic support with single hydraulic prop, such as Chinese patent: ZL200620029812.X "an electric hoist suitable for use in underground coal mines", including...

AI Technical Summary

Problems solved by technology

[0009] When assembling the hydraulic support of the above-mentioned fully mechanized mining hydraulic support, the strength of the square tube column is insufficient, the stability is poor, the positioning of the assembled parts is difficult when lifting, and the lifting parts cannot move longitudinally, which is often caused by the inappropriate placement of the hydraulic support base. The assembly is slow, and the lifting height of the components is limited, and the lifting weight is limited, which cannot meet the assembly and disassembly work of various types of hydraulic supports
