Abstract
The invention discloses an anchor bolt recycling device used for recycling mine tunnel support anchor bolts. The anchor bolt recycling device comprises a drill bit of a hollow cone structure and a spiral drill pipe, the spiral drill pipe of a tubular structure is connected to the upper end of the drill bit, a connector is arranged at the top end of the spiral drill pipe, and a convex spiral line is arranged on the outer surface of the spiral drill pipe. A mandrel with the outer diameter smaller than the bore diameter of an anchor bolt is arranged in the spiral drill pipe, the upper end of the mandrel is fixedly connected in the connector, the lower end of the mandrel is arranged to be a flared elastic forky structure, and the elastic forky structure is enabled to be combined to form a stepped tapered structure. By the structure, the anchor bolts can be removed by means of arranging the lower end of the mandrel to be the flared elastic forky structure and enabling the elastic forky structure to be combined to form the stepped tapered structure; the anchor bolt recycling device is simple in design structure, convenient to operate and use and smooth in slag tapping; meanwhile, the anchor bolts can be recycled completely, material reuse rate is increased, production cost is lowered, and raw materials are saved.
Description
?
Technical field
The present invention relates to a kind ofly for reclaiming the roofbolt recovering device of mine roadway support anchor pole, belong to coal mining equipment technical field.
Background technology
Development and extensive use along with China's coal-mine underground construction technology, mine roadway support anchor pole is used in a large number under coal mine, the safety in production in colliery has obtained further assurance, yet on the rib of existing coal mining mine laneway both sides or crag, there are many used anchor poles of scrapping, although these anchor poles are still reusable, but cannot from coal seam or rock stratum, take out smoothly always, therefore cause the waste of material and increasing of cost of production.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, easy for operation, and can be by the roofbolt recovering device of the complete taking-up of anchor pole in mine laneway.
In order to solve the problems of the technologies described above, roofbolt recovering device of the present invention, the drill bit and the auger stem that is connected to the tubular structure of drill bit upper end that comprise hollow cone body structure, the top of auger stem is provided with connector, and auger stem external surface is provided with protruding helix; In auger stem, be provided with the core bar that external diameter is less than anchor pole diameter of bore, the upper end of core bar is fixedly connected in connector, and the lower end of core bar is set to the elasticity bifurcation structure of outside spreading and makes elasticity bifurcation structure close up the pyramidal structure that rear formation has step.
There is the hole of producing coal of radially arranging on the body surface of described auger stem.
Between described auger stem and drill bit for being threaded; Between described auger stem and connector for being threaded.
Adopt after above-mentioned structure, due to the drill bit arranging and the auger stem that is connected to drill bit upper end, in auger stem, be provided with core bar, can utilize thus auger stem and drill bit to drill, then utilize core bar to extend into the center of anchor pole, can utilize thus the lower end of core bar be set to outside spreading elasticity bifurcation structure and and make elasticity bifurcation structure close up rear formation to there is the operation that the pyramidal structure of step is taken out anchor pole, project organization is simple, easy for operation, slag tap smoothly, the complete recovery anchor pole of while energy, improved material repeat usage, reduced cost of production, raw material have been saved.
Accompanying drawing explanation
Fig. 1 is the core bar deployed condition structural representation of roofbolt recovering device of the present invention;
Fig. 2 is the core bar rounding state structural representation of roofbolt recovering device of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, roofbolt recovering device of the present invention is described in further detail.
As shown in the figure, roofbolt recovering device of the present invention, comprises the drill bit 1 of hollow cone body structure and is connected to the auger stem 2 of the tubular structure of drill bit upper end, the top of auger stem 2 is provided with connector 3, and auger stem 2 external surfaces are provided with protruding helix 4; In auger stem 2, be provided with the core bar 5 that external diameter is less than anchor pole diameter of bore, the upper end of core bar 5 is fixedly connected in connector 3, and the lower end of core bar 5 is set to the elasticity bifurcation structure of outside spreading and makes elasticity bifurcation structure close up the pyramidal structure that rear formation has step.
The hole 6 of producing coal that further radially arrange in addition in the body of auger stem 2 surface, between auger stem 2 and coring bit 1 for being threaded; Between auger stem 2 and connector 3 for being threaded.
