Description
Technical field
The utility model relates to a kind of distortion roofbolt recovering device, belongs to coal mining equipment technical field.
Background technology
Along with development and the extensive use of China's coal-mine underground construction technology, mine roadway support anchor pole uses in a large number at underground coal mine, the safety in production in colliery obtains further guarantee, but the rib of existing coal mining mine laneway both sides or crag have manyly usedly scrap anchor pole, need to take out recycling to these anchor poles to save cost.
At present, market has a lot of roofbolt recovering device, but existing roofbolt recovering device can only reclaim the straight anchor pole that some are not out of shape, for some diastrophic anchor poles, cannot take out, cause waste.
Utility model content
The technical problem that the bending anchor pole existed for solving prior art cannot take out, it is simple, easy to use that the utility model provides a kind of structure, can reclaim the distortion roofbolt recovering device of bending anchor pole and straight anchor pole.
For achieving the above object, the technical scheme that the utility model adopts is distortion roofbolt recovering device, comprise wired hose, one end of described wired hose is provided with for boring with driving the jointing be connected, the other end of described wired hose is provided with hollow cone drill bit, described wired hose is also interrupted being provided with multiple reinforcing sleeve pipe.
Preferably, described wired hose end is provided with nipple, and described hollow cone drill bit is arranged on nipple.
Compared with prior art, the utility model has following technique effect: the utility model structure is simple, easy to use, and adopt wired hose to connect drill bit, such steel wire software can carry out reaming along diastrophic anchor pole, until anchor pole comes off; Facilitate removing and the dismounting of the supporting mesh in tunnel, and effectively improve material repeat usage, reduce cost of production, save raw material.
In addition, wired hose is interrupted and is provided with multiple reinforcing sleeve pipe, reinforce the intensity that sleeve pipe effectively can strengthen wired hose.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, distortion roofbolt recovering device, comprises wired hose 1, and one end of described wired hose 1 is provided with for boring with driving the jointing 2 be connected, the other end of described wired hose 1 is provided with hollow cone drill bit 3, described wired hose 1 is also interrupted being provided with multiple reinforcing sleeve pipe 4; Described wired hose 1 end is provided with nipple 5, and described hollow cone drill bit 3 is arranged on nipple 5.
During use, first jointing 2 is connected with rig, back out the anchor nut of needs dismounting, take off anchor rod pallet board, hollow cone drill bit 3 is inserted in anchor pole afterbody, and opening rig can creep into deep along anchor pole, the hole wall around first broken anchor pole, then Anchor Agent is broken, make anchor pole depart from rock mass, extract drilling tool and anchor pole out, dismounting work completes.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should wrap within the scope of the utility model.
