Description
Technical field
The utility model is related to Grouting Pipe field, particularly relates to a kind of recyclable termination frictional rock bolt.
Background technology
Suspension roof support can effectively control coal mine down-hole tunnel surrouding rock deformation, obtain excellent supporting effect, at home and abroad
Underground coal mine is widely used and quickly developed.The effect of anchor pole is mainly reinforcing, compound girder, suspention etc., anchor pole
Force-bearing of surrounding rock mass state can be changed in supporting, the stability of country rock in itself is on the one hand added, on the other hand promote country rock to be formed
Bearing structure, improves its bearing capacity.In addition, a large amount of engineering practices show, the first current cost of suspension roof support is low, drift section is empty
Between occupancy is small, construction technology simple, easy for installation, labor intensity is small and can preferably adapt to roadway deformation, thus, anchor
Bar supporting is widely popularized, the principal mode as home and abroad colliery supporting.
Anchor pole used in domestic is mostly ordinary resin anchor metal, and its body of rod is as disposable consumption articles for use, in lane
Is generally discarded after road is discarded in coal and rock, not only forms underground garbage, cause environmental pollution, at the same also reduce through
Ji benefit.With the downslide of coal economy in recent years, reduction coal production cost turns into standing in the breach for task, therefore,
Seek a kind of supporting intensity height, construction technology simply and repeat the anchor pole utilized, to further reduction support cost, raising
The economic benefit of suspension roof support, reduction cost of ton coal tool important in inhibiting.
Utility model content
The utility model proposes a kind of recyclable termination frictional rock bolt, solve that anchor pole in the prior art is not reproducible to be made
With, as underground garbage after discarding, pollution environment, the problem of cost is higher.
What the technical solution of the utility model was realized in：
A kind of recyclable termination frictional rock bolt, including bolt body, in addition to handle, rub sleeve pipe and ball of pulling back；Institute
The one end for stating bolt body is provided with pallet, and handle is on pallet, and the other end of bolt body is provided with thread head, thread head peripheral hardware
There is friction sleeve pipe, provided with rope of pulling back between thread head and ball of pulling back, rope of pulling back connects thread head and ball of pulling back through friction sleeve pipe
Pick up and.
Antiskid particles are evenly distributed with the friction bushing outer surface.
The internal diameter of the friction sleeve pipe is less than the external diameter of thread head, and the diameter for ball of pulling back is more than the internal diameter of friction sleeve pipe.
The number of the handle is 2-4.
The beneficial effect that the technical program can be produced：Recyclable termination frictional rock bolt of the present utility model is in roadway support
By the cooperation of the thread head in bolt body and friction sleeve in use, when thread head is completely into friction sleeve,
Rubbed sleeve expansion, and bolt body is firmly secured in drilling；, will by rotating backward handle when needing to reclaim anchor pole
Thread head rotates out of friction sleeve pipe, and the frictional force now rubbed between sleeve pipe and drilling reduces, and bolt body is pulled, by pulling back
Spherical zone dynamic friction sleeve pipe takes out recyclable termination frictional rock bolt of the present utility model, realizes recycling.The utility model
Solve that anchor pole in the prior art is not reproducible to be used, turn into underground garbage after discarding, pollute environment, the problem of cost is higher.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is planar structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belongs to the scope of the utility model protection.
As shown in figure 1, the utility model embodiment provides a kind of recyclable termination frictional rock bolt, including bolt body
6, in addition to handle 7, friction sleeve pipe 2 and ball 1 of pulling back；One end of the bolt body 6 is provided with pallet 8, and handle 7 is located at pallet 8
On, the other end of bolt body 6, which is provided with outside thread head 5, thread head 5, is arranged with friction sleeve pipe 2, between thread head 5 and ball 1 of pulling back
Provided with rope 3 of pulling back, rope 3 of pulling back connects thread head 5 with ball 1 of pulling back through friction sleeve pipe 2.
Recyclable termination frictional rock bolt of the present utility model passes through the screw thread in bolt body 6 in roadway support use
First 5 with friction sleeve 2 cooperation, when thread head completely into friction sleeve 2 when, friction sleeve 2 expand, by bolt body
6 are firmly secured in drilling；When need reclaim anchor pole when, by rotate handle 7 by thread head 5 rotate out of friction sleeve pipe 2, this
When friction sleeve pipe 2 and drilling between frictional force reduce, pull bolt body 6, by pull back ball 1 drive friction sleeve pipe 2 will this
The recyclable termination frictional rock bolt of utility model takes out, and realizes recycling.The utility model solves anchor in the prior art
Bar turns into underground garbage after a single use, pollutes environment, the higher technical problem of cost.
It is preferred that, it is evenly distributed with antiskid particles 4 on the above-mentioned outer surface of friction sleeve pipe 2.
It is preferred that, the internal diameter of above-mentioned friction sleeve pipe 2 is less than the external diameter of thread head 5, and the diameter for ball 1 of pulling back is more than friction sleeve pipe
2 internal diameter.
It is preferred that, above-mentioned handle 7 is fixed on pallet 8 by knee 9, and the number of handle 7 is 2-4.
The utility model application method is：
First, after friction sleeve pipe 2 is gently enclosed on thread head 5, anchor pole is inserted and drilled, rotated handle 7, make thread head
5 screw engaging friction sleeve pipe 2 by screw thread, because the friction internal diameter of sleeve pipe 2 is slightly less than the external diameter of thread head 5, are squeezed by thread head 5
Press, friction sleeve pipe 2 produces expansion, firmly block in the borehole, while pallet 8 tightly can be stuck in wall, so as to realize anchoring
Effect.When removing anchor pole, handle 7 is rotated backward, friction sleeve pipe 2 is separated with thread head 5, thread head 5 drops ball 1 of pulling back, and
The diameter of ball 1 of pulling back is more than the friction internal diameter of sleeve pipe 2, can pull out friction sleeve pipe 2 together.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
