Crawler-type non-repeated-supporting single-span support carrier

Abstract

The invention belongs to the technical field of design and manufacturing of efficient supporting and transporting equipment for underground coal mine supporting columns, and particularly relates to acrawler-type non-repeated-supporting single-span support carrier. A rack is arranged on a crawler belt assembly. A main cab, an auxiliary cab, an oil tank, a diesel engine system and an electrical system are arranged in front of and behind the rack. A lifting clamping platform is arranged in the middle of the rack. The lifting clamping platform comprises a lifting platform supporting frame. A double-fork lifting platform and the rack are connected to the lifting platform supporting frame in a supporting mode. The double-fork lifting platform is controlled to ascend and descend by two lifting oil cylinders controlled by a platform hydraulic system. A rotary table capable of rotating is arranged in the middle of the double-fork lifting platform. A limiting device is arranged on the outer side of the double-fork lifting platform. A distance sensor is arranged on the upper side of the double-fork lifting platform. A clamping device is arranged on the rotary table. A rotary shaft center isarranged at the bottom of the rotary table. A protruding block is arranged on the rotary shaft center and hinged to the liquid filling rod end of a rotary clamping oil cylinder, and the other end of the rotary clamping oil cylinder is fixed.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of high-efficiency support for underground pillars in coal mines and transportation equipment, in particular to a crawler-type non-repeatedly supported single-span support carrier. Background technique [0002] With the expansion of my country's coal mine mining scale and the increase of mining intensity and production capacity, higher requirements have been put forward for the advance support along the groove of the fully mechanized mining face. The support is easy to cause damage to the roof and is difficult to maintain, which poses a great safety hazard to the safety of pedestrians and operators in the roadway. In order to solve the problem of advanced support for the broken roof of the dynamic pressure roadway at the outlet of the working face, a circulating advanced support and a wheeled support truck have been developed. The operator only needs to operate the centralized contro...

AI Technical Summary

Problems solved by technology

However, for some mines with no hardening of the floor of the tunnel roadway and complex road conditions, it will cause difficulty in driving the wheeled support truck, poor passability, high specific pressure to the ground, and difficulties in transporting materials in some mines with large slopes.
