Mechanical single-arm type hydraulic roof-bolter

Abstract

The invention relates to a drilling machine, particularly relates to a mechanical single-arm type hydraulic roof-bolter adopting a hydraulic cylinder chain-type doubling mechanism. The mechanical single-arm type hydraulic roof-bolter comprises a power source of a hydraulic power system for providing hydraulic power, a sliding rail component fixedly arranged on the machine body of a development machine, a sliding table, a telescopic arm in with one end is hinged with the sliding table, a connecting seat of a drilling frame connected with the other end of the telescopic arm, and a drilling frame connected with the connecting seat. The power of the hydraulic system is provided by multiple modular gear pumps in a main pump station of the development machine, so that the power source of the hydraulic system does not need to be added additionally; a sliding and pulling part of the onboard roof-bolter adopts the hydraulic cylinder chain-type doubling mechanism to realize transmission, so that the puling part has compact structure and less weight; and the drilling box adopts a non-round planetary gear transmission hydraulic motor, and the pulling part of the drilling box adopts the hydraulic cylinder chain-type doubling mechanism to realize transmission, so that the drilling frame has a compact structure and light weight.

Description

technical field [0001] The invention relates to a drilling rig, in particular to a mechanical single-arm hydraulic rock bolt drilling rig adopting a hydraulic cylinder chain type doubling mechanism. Background technique [0002] Patent 95240096.0 proposes an airborne rock bolter, which has an independent hydraulic source, and the sliding table is pushed on the long slideway by the piston rod of the slide table cylinder, making the sliding propulsion part of the airborne rock bolter too large , the weight increases. Simultaneously, the rig structure proposed by it is complex, and the worm screw is manually shaken to realize the swing of the slideway frame around the column oil cylinder, which is very unsafe when operated by personnel. [0003] Patents ZL200620024359.3 and ZL200620024357.4 propose a plurality of airborne bolter devices installed on the cutting arm, which is complicated to operate, and affects the sight of the roadheader driver during the cutting operation, re...
