Abstract

The invention belongs to mining machinery, in particular to an explosion-prevention full hydraulic crushing road header used for advancing a solid and a rock road in mining area. The road header consists of a frame (27), a control valve box (10), a gasoline tank (4), a main control valve (13), a hydraulic oil radiator (18), a running motor (20), an apron wheel (22), a guide wheel (23) and a turntable (21). An explosion-proof electric machine (19) is arranged at the tail of the frame (27). The output shaft of the explosion-proof electric machine is provided with a general hydraulic pump (17). The front of the frame (27) has hinge connection with a large arm (30). The hydro cylinder with a small arm (9) is fixed on the right of the frame and the hydro cylinder with the large arm (28) is fixed on the left of the frame. The piston rod (28-1) of the hydro cylinder with the large arm has hinge connection with the large arm (3). The road header has strong impact, high production efficiency, little dust, simple structure and easy manipulation. So the road header is especially suitable for the advancement of the tunnel with small section.

Description

Mine explosion-proof coal rock full hydraulic pulverizing development machine

Technical field

The invention belongs to mine equipment, the mine explosion-proof coal rock full hydraulic pulverizing development machine that particularly a kind of mining excavation coal road, rock gangway are used.

Background technology

At present, both at home and abroad the road heading machinery kind of using in the mine is more, as use more have ELMB type development machine, AM-50 type development machine etc. in the colliery; In engineerings such as railway tunnel, city underground, Rubens's type development machine produced in USA is arranged, the development machine that Europe, Japan manufacture, above-mentioned various development machine complex structures, cost height, limit the use of in big section coal petrography tunnel, they can't use for the light section tunnel in the little ore deposit, so in the driving of little ore deposit, the way that often adopts hand-holing to blow out, production efficiency is low, and labour intensity is big.

Summary of the invention

The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of simple in structure, easy to operate, be particularly suitable for the mine explosion-proof coal rock full hydraulic pulverizing development machine of light section coal petrography tunnelling.

The technical scheme that technical solution problem of the present invention adopts is: a kind of mine explosion-proof coal rock full hydraulic pulverizing development machine of being made up of frame, control clack box, fuel tank, main control valve, hydraulic oil radiator, running motor, crawler belt, guide wheel and rotating disk, be characterized in fixing a fire-proof motor, on the fire-proof motor output shaft hydraulic total pump be housed at the frame rear portion; Be hinged a big arm at frame front, fix a forearm oil cylinder on the right side of big arm, fix a big arm oil cylinder on the left side of big arm, forearm oil cylinder piston bar and forearm are hinged, and big arm oil cylinder piston bar and Da Bi are hinged; Between big arm and the forearm for being hinged; Bucket cylinder is housed on the forearm, and the bucket cylinder piston rod is hinged with guiding push rod and push rod one end, and the guiding push rod other end and forearm are hinged, and the push rod other end and quartering hammer outrigger are hinged; Quartering hammer outrigger and forearm are hinged, and fix an operating cyloinder with little axle and axle card and screw below it; Fix frame in the quartering hammer in the quartering hammer outrigger, fixing quartering hammer in the frame in quartering hammer.

The invention has the beneficial effects as follows: this development machine adopts explosion-proof, full hydraulic pulverizing, and impact force is big, the production efficiency height; Dust is little, the water dirt that disappears not, and favourable safety in production, simple in structure, cost is low, and is easy to operate, personnel's few (only needing two people), the driving that is particularly suitable for the light section tunnel uses.
