Fully mechanized coal mining face transportation crossheading unit support carrying system

Abstract

The invention provides a fully mechanized coal mining face transportation crossheading unit support carrying system. The fully mechanized coal mining face transportation crossheading unit support carrying system comprises a reversed loader, an annular hoisting device and a plurality of unit supports arranged on the two sides of a roadway, wherein the annular hoisting device comprises a driving device, an annular guiding device and a hoisting trolley; the annular guiding device is installed above the reversed loader; the hoisting trolley is arranged below the annular guiding device in a hoistedmode; the driving device drives the hoisting trolley to move along the annular guiding device; the advancing path of the hoisting trolley is arranged around the two sides and the rear portion of thereversed loader; and the hoisting trolley is provided with hoisting tools corresponding to the unit supports. The fully mechanized coal mining face transportation crossheading unit support carrying system has the advantages that repeated supporting is avoided, a top plate is not prone to being damaged, operation is easy and convenient, and the working efficiency is high.

Description

technical field [0001] The invention relates to a coal mine machine, in particular to a fully mechanized mining working face transport and trough unit support handling system. Background technique [0002] The advanced support is an important support equipment in coal mining. The traditional advanced support generally adopts a single hydraulic prop, an ordinary advanced support support and a unit support. Among them, the single hydraulic prop needs to be moved manually, which is time-consuming and laborious, and the labor cost is high; The advanced support bracket adopts the front frame and the rear frame to support alternately, which are the fulcrums of each other, and then use the moving jack to push the frame and pull the frame to move forward alternately. During the actual use of the roadway, there are repeated supports on the roof, which aggravates the damage to the roof and affects the rapid advancement of the working face. [0003] Although the unit bracket can be su...

[0003] Although the unit bracket can be supported without repeated support, it is difficult to transfer in the roadway with limited space. In the prior art, there is a monorail crane laid on the top of the roadway to move the unit bracket. The lifting equipment needs to be disassembled and assembled repeatedly, the labor intensity of workers is high, and the work efficiency is low; in the prior art, there is also a method of laying tracks on the reloading machine and supporting the portal support, but the support strength of the portal support is relatively low. Low, when the track is laid on the reloader, it is difficult to walk at the crusher and the bridge section, and the operation is complicated
