Embodiment Construction

[0029] The specific embodiments of the present invention will be further described with reference to the drawings.

[0030] 1. The layout of the whole machine.

[0031] The invention mainly consists of a frame, a workbench, a temporary support, a ceiling, a connecting rod mechanism, front and rear slide rails, a coiled cable, a hydraulic system, an electrical system, an anchor drilling system, a dust removal system, etc.

[0032] In the case of the same width as the four bolt rigs, and slightly changed machine height and captain length, four drill booms, four sets of dust removal systems, and the volume of the hydraulic oil tank are increased. Eight bolts can be supported at the same time at the same time, which can meet the bolt support of 4500-6000 roadways. Under better roadway conditions, the practical performance is improved to ensure the tunneling speed of the roadway.

[0033] The main technical parameters of the invention:

[0034]

[0035] 2. Highly integrated dust removal sys...

Abstract

The invention belongs to the technical field of anchor rod drill carriages for coal mines, in particular relates to a hydraulic eight-arm anchor rod drill carriage for a coal mine, and solves the problem that the supporting speed of the conventional four-arm anchor rod drill carriage is lower than that of a continuous coal mining machine. The hydraulic eight-arm anchor rod drill carriage for the coal mine comprises a frame, a workbench, a ceiling, an anchor drill system and a dust removal system, wherein four groups of drilling frames are arranged on the front and rear sides of the workbench; and gaps among the drilling frames on the front and rear sides are adjustable. The invention has the advantages that: eight anchor rods in two rows can be supported simultaneously, the hydraulic eight-arm anchor rod drill carriage can better adapt to the construction of high-yield and high-efficiency mines at present, supporting efficiency can be obviously improved, and labor intensity is effectively reduced; and the roadway forming speed of the hydraulic eight-arm anchor rod drill carriage matched with the continuous coal mining machine can be improved to be 1.5 times that of the four-arm anchor rod drill carriage matched with the continuous coal mining machine, the contradiction of excavating and supporting is solved, and a wide market prospect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of a coal bolt drill carriage, and in particular relates to a hydraulic eight-arm bolt drill carriage for coal mines. Background technique [0002] Existing rock bolt rigs, such as Chinese Patent 200410012344.0, discloses a crawler-type walking rock bolt rig, which includes a base, a workbench, a running mechanism, a lifting mechanism, a hydraulic mechanism, a dust removal mechanism, a cable winding mechanism, Drill frame components, slide rail components, support components, electric control box, the whole machine adopts hydraulic transmission, automatic dust removal, automatic winding cable, crawler walking, hydraulic cylinders dominate the parallelogram lifting, which can be moved, lifted, and moved in the mining tunnel. The multi-arm bolt drilling operation makes the anchor drill support fully mechanized. The drill rig adopts explosion-proof design, reasonable structure, large bearing capacity, free and relia...
