Embodiment 1

[0022] Embodiment one: if figure 1 As shown in and 2, in the present embodiment, the coal roadway rapid bolting integrated equipment under unstable surrounding rock conditions includes a bolter 1, a bolter 2, and the bolter 1 includes a cutting drum 11, a draft Pipeline 12, material collector 13, rock bolter unit 14 and scraper conveyor 15, described rocker drill 2 includes rocker drill unit 21 and scraper conveyor 23, and described rocker drill 2 is arranged at the excavation The rear of the windlass 1 and the rear of the scraper conveyor 15 of the bolter 1 is above the front of the scraper conveyor 23 of the bolter 2, and the bolter 1 is provided with an anti-roof fall device 16, The bottom of the anti-roofing device 16 is connected with a sealing device 17, and the sealing device 17 is composed of a movable sealing rubber 171, a fixed sealing rubber 172, a telescopic oil cylinder 173, a beam 174, and a telescopic beam 175, and the beam 174 is connected to the telescopic oi...

Embodiment 2

[0025] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the bolter 1 is symmetrically provided with two anti-chip side devices 18, and the anti-chip side The device 18 is composed of a lower guard plate 181, an upper guard plate 182, a telescopic oil cylinder 183 and an adjustment oil cylinder 184. Both sides of the upper end of the lower guard plate 181 are provided with chute, and the upper guard plate 182 is slidably connected to the lower guard plate 181. In the chute, the lower guard plate 181 is connected to the cylinder barrel of the telescopic oil cylinder 183, the upper guard plate 182 is connected to the piston rod of the telescopic oil cylinder 183, and the lower guard plate 181 is also connected to the piston rod of the adjustment oil cylinder 184, so The cylinder barrel of the adjustment oil cylinder 184 is hinged on one side of the collector 13 .

Abstract

The invention discloses rapid drivage-anchoring integrated equipment for a coal road under an instable surrounding rock condition. The equipment comprises a drivage-anchoring machine and an anchor rod drill carriage, the drivage-anchoring machine comprises a cutting roller, an air draft pipeline, a material collector, an anchor rod drilling machine set and a scraper conveyor, the anchor rod drill carriage comprises an anchor rod drill drilling machine set and a scraper conveyor, the anchor rod drill carriage is arranged behind the drivage-anchoring machine, the rear portion of the scraper conveyor of the drivage-anchoring machine is located over the front portion of the scraper conveyor of the anchor rod drill carriage, a roof-caving-preventing device is arranged on the drivage-anchoring machine, a sealing device is connected below the roof-caving-preventing device, the sealing device is composed of a moving sealing rubber sheet, a fixed sealing rubber sheet, a telescopic oil cylinder, a cross beam and a telescopic beam, the cross beam is connected with one end of the telescopic oil cylinder, the other end of the telescopic oil cylinder is connected with the telescopic beam, the fixed sealing rubber sheet is connected below the cross beam, and the moving sealing rubber sheet is connected below the telescopic beam. By means of the equipment, the anchoring efficiency can be matched with the drivage efficiency, and the comprehensive drivage-anchoring efficiency is promoted.

Description

technical field [0001] The invention relates to an underground bolt-digging construction equipment for mines, in particular to an integrated equipment for quick-digging and bolt-digging coal roadway under unstable surrounding rock conditions. Background technique [0002] At present, the main equipment for the mechanized rapid excavation of coal mine underground roadway includes: roadheader, continuous miner, and bolter. Under the condition of unstable surrounding rock, the bolter is the first choice for coal roadway excavation due to the limitation of empty roof distance. Roadway comprehensive mechanized rapid excavation is a system that integrates cutting, loading, transfer, support, auxiliary transportation, etc., and any link restricts the excavation efficiency of the entire system. In order to realize rapid excavation with the existing bolt-digging equipment, several problems must first be solved, such as the matching between excavation and support, supporting equipmen...
