Description
Technical field
This utility model belongs to mine support anchor pole and takes out technical field of tools, particularly to a kind of anchor pole withdrawing device.
Background technology
Anchor pole is the most basic ingredient of roadway support in the middle of colliery in the present age, he by the surrounding rock consolidation in tunnel one
Rise, make country rock self supporting self.Anchor pole is as going deep into the tensional element on stratum, and its one end is connected with engineering structure, another
End gos deep in stratum, and whole anchor pole is divided into free segment and anchoring section, and free segment refers to that the pulling force at by anchor pole head reaches anchoring body
Region, its function is to anchor pole Shi Hanzhang；Anchoring section refers to the cement slurry region by presstressed reinforcing steel with soil layer bonding,
Its function is the bonding rubbing action of anchoring body with soil layer to be increased, and increases the pressure-bearing effect of anchoring body, by the pulling force of free segment
Reach soil body depths.Anchor pole is applied not only to mine now, is also used in engineering, and to side slope, tunnel, dam body carries out main body and adds
Gu.
Along with the expansion of anchor pole range, the crag of coal mining mine laneway both sides still remains many used reports
Useless anchor pole, is wherein no lack of the anchor pole of some recyclable recyclings, but anchor pole cannot take out simply and easily in crag, makes
Become the waste of material and increasing of production cost.
Utility model content
In order to be taken out in crag simply and easily by used anchor pole, increase the recycling rate of waterused of waste anchor rods, fall
Low production cost, this utility model provides a kind of anchor pole withdrawing device.
This utility model is achieved by the following technical programs.
A kind of anchor pole withdrawing device, it includes drill bit, bores tail and drilling rod, it is characterised in that described drilling rod is hollow stem, bores
End, lateral wall, bar two ends is respectively arranged with external screw thread, and drilling rod one end and external screw thread are cooperatively provided with drill bit, drilling rod another
End and external screw thread are cooperatively provided with brill tail, and drilling rod is provided with helical blade on lateral wall；Described drill bit free end is provided with
Through hole, described through hole internal diameter hollow with drilling rod is identical, and through-hole wall is provided with the female thread matched with anchor pole；Described brill tail end
Middle face is fixedly installed square steel, and the free end of described square steel connects with electric drill.
Further, described helical blade is continuous right hand helix shape blade.
Further, described drill bit free end end face is provided with three-jaw claw.
Further, it has been evenly arranged square pit along drill bit circumferencial direction in the middle part of described drill bit outer wall.
Further, being fixedly installed adapter in the middle part of described brill breech face, adapter is inserted into square steel.
This utility model compared with prior art has the advantages that.
1, it is provided with, on this utility model drill bit, the female thread matched with anchor pole, anchor pole can be screwed in this utility model
In, by continuous rotating motion of the present utility model, the crag around helical blade cutting anchor pole so that anchor pole loosens, it is simple to
Anchor pole is taken out.
2, this utility model driving force is electric drill, is the common instrument in construction, and electric drill connects with boring WEILIAN, can be by changing
Carry different-diameter and bore the electric drill of tail adaptation different model, drive this utility model to rotate thus by anchor pole from rock by electric drill
Wall takes out, increases the recycling rate of waterused of waste anchor rods, reduce production cost.
Accompanying drawing explanation
Fig. 1 is to bore breech face in this utility model to be fixedly installed the overall structure partial schematic sectional view of square steel.
Fig. 2 is the overall structure partial schematic sectional view being connected square steel in this utility model by adapter.
In figure, 1, square steel 2, bore tail, 3, drilling rod, 4, helical blade, 5, drill bit, 6, pit, 7, three-jaw claw, 8, through hole,
9, adapter.
Detailed description of the invention
As shown in Figure 1 and 2, a kind of anchor pole withdrawing device, it includes drill bit 5, bores tail 2 and drilling rod 3, it is characterised in that described
Drilling rod 3 is hollow stem, and end, lateral wall, drilling rod 3 two ends is respectively arranged with external screw thread, and drilling rod 3 one end cooperatively sets with external screw thread
Being equipped with drill bit 5, drilling rod 3 other end is cooperatively provided with brill tail 2 with external screw thread, and drilling rod 3 is provided with helical blade on lateral wall
4, in the present embodiment, helical blade 4 is continuous right hand helix shape blade, it is simple to produced because of cutting crag by anchor pole periphery is useless
Material strip goes out crag.
Described drill bit 5 free end is provided with through hole 8, and described through hole 8 internal diameter hollow with drilling rod 3 is identical, and through hole 8 inwall is arranged
There is the female thread matched with anchor pole, anchor pole can be screwed in drill bit 5 or even hollow drill 2, it is simple to anchor pole is taken out.
Being fixedly installed square steel 1 in the middle part of described brill tail 2 end face, the free end of described square steel 1 connects with electric drill, with electric drill is
Driving force, makes screw thread blade 4 cut the crag around anchor pole convenient and strength-savingly.
Further, described drill bit 5 free end end face is provided with three-jaw claw 7, it is ensured that drill bit and the axiality of anchor pole,
Make anchor pole can be taken out by electric drill practical process quickly.
Further, it has been evenly arranged square pit 6 along drill bit 5 circumferencial direction in the middle part of described drill bit 5 outer wall, it is simple to artificial
Drill bit 5 is stably installed on drilling rod 3 by utility.
Further, being fixedly installed adapter 9 in the middle part of described brill tail 2 end face, adapter 9 is inserted into square steel 1, no
With square steel 1 both sides respectively coupling adapter 9 and the electric drill of diameter, make the electric drill of different model on building site can be quick by anchor pole
Ground takes out from crag.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
