Abstract
The utility model discloses a recyclable anchor rod which comprises an unrecyclable rod body and a recyclable rod body. The unrecyclable rod body comprises a hollow tube and a drill bit connected with the hollow tube, and an internal thread is arranged in the drill bit. The front end of the recyclable rod body is provided with an outer thread which is matched with the inner thread in the drill bit, and the front end of the recyclable rod body extends into the hollow tube and is in screwed connection with the drill bit. The recyclable anchor rod comprises the unrecyclable rod body and the recyclable rod body which are connected through a thread connecting structure, mounting of the anchor rod and recycling of the recyclable rod body of the anchor rod are achieved through forward rotation and reverse rotation, and the problem that the anchor rod can not be recycled is effectively solved.
Description
Technical field
The utility model relates to a kind of coal mine support anchor pole, is specifically related to a kind of recoverable anchor rod.
Background technology
Anchor pole is the most basic ingredient of roadway support in the middle of contemporary colliery, for by the surrounding rock consolidation in tunnel together, makes country rock self supporting self.Now anchor pole is not only for mine, also for engineering, and to side slope, tunnel, dam body carries out active reinforcing.
In bolt support, for reducing support cost, energy conservation, eliminates underground environmental pollution, and the recovery of anchor pole becomes urgent problem.Because the very firm of Anchor Agent anchoring used in anchor rod body one end in hole wall, during recovery, with draw-off gear, the body of rod to be pulled out by force in hole wall, the body of rod that not only make lever strength reduce, distortion is large, reclaims should not be multiplexing.
Utility model content
Technical problem to be solved in the utility model is the problem that anchor pole can not recycling.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of recoverable anchor pole, it comprises can not reclaim the body of rod and the recyclable body of rod, the described body of rod that can not reclaim comprises hollow tube and the drill bit being connected with described hollow tube, in described drill bit, establish internal thread, the front end of the described recyclable body of rod be provided with described drill bit on the suitable external screw thread of internal thread, the front end of the described recyclable body of rod stretches into described hollow tube and spins with described drill bit.
Preferably, described hollow tube is manufactured by highstrenghtpiston.
Preferably, described hollow tube and described drill bit are injected into one.
Preferably, the outer circumference surface of described hollow tube is provided with a plurality of outwardly projections.
Preferably, a plurality of described projections form external screw thread shape on the outer circumference surface of described hollow tube.
Preferably, described drill bit is manufactured by steel.
The recoverable anchor pole that the utility model provides, comprise by helicitic texture, connect can not reclaim the body of rod and the recyclable body of rod, by forward and reverse rotation, realize the installation of anchor pole and the recovery of the recyclable body of rod of anchor pole, efficiently solve the problem that anchor pole can not recycling.
Accompanying drawing explanation
The structural representation of the recoverable anchor pole that Fig. 1 provides for the utility model.
In figure, 1: can not reclaim the body of rod; 2: the recyclable body of rod; 3: drill bit; 4: nut; 5: pallet; 6: pad; 7: ball pad.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the recoverable anchor pole that the utility model provides comprises can not reclaim the body of rod 1 and the recyclable body of rod 2, the body of rod 1 be can not reclaim and hollow tube and the drill bit 3 being connected with hollow tube comprised, in drill bit 3, establish internal thread, the front end of the recyclable body of rod 2 be provided with drill bit 3 on the suitable external screw thread of internal thread, the front end of the recyclable body of rod 2 stretches into hollow tube, and spins with drill bit 3.
The recoverable anchor pole that the utility model provides, it can not reclaim the body of rod and comprise drill bit, has realized the Fast Installation of anchor pole; By the internal thread that arranges in drill bit and recyclable lever front end setting make to reclaim the body of rod with the suitable external screw thread of internal thread and the recyclable body of rod interconnects, the recyclable body of rod is by forward and reverse rotation, realize the installation of anchor pole and the recovery of the recyclable body of rod of anchor pole, reached the recyclable recycling of the recyclable body of rod of anchor pole.
In the utility model, the recyclable body of rod 2 is the front end of the recyclable body of rod 2 near the one end that can not reclaim the body of rod 1, away from the one end that can not reclaim the body of rod 1, is the rear end of the recyclable body of rod 2.
When guaranteeing anchor rod anchored intensity, for cost-saving, hollow tube is made by high strength plastics.
For improving the anchoring strength that can not reclaim the body of rod, hollow tube and the drill bit 3 that can not reclaim the body of rod 1 are injected into one.
Concrete, the recoverable anchor pole that the utility model provides, comprise and can not reclaim the body of rod 1 and the recyclable body of rod 2, can not reclaim the body of rod 1 and be injected into one by hollow tube and drill bit 3, and be provided with internal thread in drill bit 3, the front end of the recyclable body of rod 2 is provided with the external screw thread suitable with the internal thread of drill bit 3, and the front end spinning of the recyclable body of rod 2 is on drill bit 3, and the rear end of the recyclable body of rod 2 is provided with pallet 5, ball pad 7, pad 6 and nut 4 successively.
Concrete, 4, nut is at one end connected with roof-bolter head by adapter sleeve, drill bit 3 inserts and has installed in the petrosal foramen of Anchor Agent, rise roof-bolter and utilize and can not reclaim the body of rod 1 and the recyclable body of rod 2 pushes to the Anchor Agent in aperture in hole, till making Anchor Agent touch at the bottom of hole, then start to rotate roof-bolter and stir Anchor Agent.
Anchor Agent solidifies after certain hour, carries out the work of top tray 5.Adopt spanner fastening nut 4, make pad 6 and ball pad 7 constantly promote pallet 5 reaches, make pallet 5 be adjacent to as much as possible crag.
For improving, can not reclaim the frictional force between the body of rod and hole wall, preferred, the hollow tube outer circumference surface that can not reclaim the body of rod 1 is set to external screw thread shape.
The recoverable anchor pole that the utility model provides, its using method is as follows:
The front end of the recyclable body of rod 2 of anchor pole deeply can not be reclaimed in the hollow tube of the body of rod 1, be rotatably connected with drill bit 3, drill bit 3 at one end inserts petrosal foramen, can not reclaim the body of rod 1 and deeply boring of the recyclable body of rod 2, and the Anchor Agent of drill bit 3 front ends is installed in petrosal foramen together under the drive of roof-bolter, until at the bottom of Anchor Agent touches petrosal foramen hole, turn clockwise, stir, successively tray 5, ball pad 7 and pad 6, use spanner fastening nut 4, make pallet 5 be close to crag;
Roadway support service is complete, uses spanner to turn on nut 4, opens ball pad 7, pad 6 and pallet 5, rotates counterclockwise the recyclable body of rod 2, and the recyclable body of rod 2 is extracted out.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
