Abstract
The utility model relates to a from formula stock that rises, it includes drill way clamp plate (5) and passes the stock body of rod (1) of drill way clamp plate (5), the stock body of rod (1) upper band is threaded and threaded connection has nut (4), the outside of nut (4) has been offered in the steel band that expands bayonet socket groove (41), and the inboard of drill way clamp plate (5) has been offered from expand steel band outer bayonet socket groove (51), still including seting up expanding steel band (2) certainly of a plurality of bar hole, the stock body of rod (1) is passed in proper order a plurality of bar hole makes and is even wave from expand steel band (2), be arranged in respectively outside expand steel band bayonet socket groove (41) and steel band bloated certainly bayonet socket groove (51) from the inner of expand steel band (2) and outer end. The utility model discloses from formula stock that rises realizes whole connection to its broken rock mass that passes, and fundamentally has changed rock mass force -bearing mode, increase substantially the area of contact between stock and the rock mass, consequently increased substantially the anchor reliability.
Description
Technical field
This utility model relates to a kind of self expansion anchor pole, is mainly used in ore deposit rock and reinforces.
Background technology
The existing anchor pole for advance support generally pushes up wedge-type, and bottom anchor hole, ore deposit rock bears pulling force, and strains anchor hole mouth backing plate by anchor rod body, is used for fixing around anchor hole broken ore deposit rock.Owing to bottom anchor hole, stress compares concentration, when bottom hole, position rock mass holds the pulling force that can't stand anchor pole, the rock mass around anchor hole arises that inbreak, causes fastening invalidation.
Existing anchor cable is frequently used for anchoring Mine Stope top board, tunnel and lane, ore deposit.But need first to carry out gib, then anchor cable is placed in anchor hole and the material such as filling expansion cement, after solidification, play anchorage effect.The shortcoming of this way is: in gib to anchor cable load during this period of time, and ore body structure and force-bearing situation have occurred and that the biggest change, is unfavorable for that the later stage takes measures.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of self expansion anchor pole, by changing rock mass force way, improves anchorage reliability.
In order to solve the problems referred to above, this utility model have employed techniques below scheme.
A kind of self expansion anchor pole, is characterized in that: it includes aperture pressing plate and the anchor rod body through aperture pressing plate, and the outer end of anchor rod body is with nut；It is threaded on anchor rod body and threaded has nut；The outside of described nut offers from swollen steel band inner bayonet groove, and the inner side of described aperture pressing plate offers from swollen steel band outer bayonet groove；Self expansion anchor pole also include offering several bar holes from swollen steel band, described anchor rod body sequentially pass through several bar holes described make from swollen steel band be homogeneous wave shape wave；Be positioned at described in swollen steel band inner bayonet groove from the inner of swollen steel band, outer end is positioned at described in swollen steel band outer bayonet groove.
Offer pack hole on the pressing plate of aperture, be used for inserting filling pipe in anchor hole, inject expanding material.
Also it is installed with the spacer pin being positioned at inside nut on anchor rod body, is used for preventing nut from coming off from inner side.
Described anchor rod body is screw configuration in the range of nut travel, and remainder is smooth shaft, and described bar hole is smooth hole wall.
After using above technical scheme, create following good effect:
Self expansion anchor pole of the present utility model can be after tunneling into lane, periphery ore deposit rock mass does not occurs implementing advanced anchoring when STRESS VARIATION or STRESS VARIATION are less, self expansion anchor pole realizes entirety connection to its fragmented rock body passed, fundamentally change rock mass force way, increase considerably the contact area between anchor pole and rock mass, anchorage reliability has therefore been greatly improved.
For permanent anchoring, it is not necessary to remove in the case of reclaiming, aperture pressing plate offers pack hole.During use, first by self expansion rockbolt installation of the present utility model to anchor hole and make it expand, then insert filling pipe from pack hole and inject the materials such as expanding cement in anchor hole.This mode not only further enhancing anchoring effect, and can make to keep the original state after expanding from swollen steel band, alleviates the degree of fatigue from swollen steel band, increases substantially service life of the present utility model.
This utility model can be widely applied to mining, the ore deposit rock of tunnel digging is reinforced, the rock mass reinforcing of geological hazard control, and construction of structures is reinforced, tractive earth anchor pulling force increase etc..There is simple in construction, easy to make, it is possible to the features such as recycling.

Fig. 2 is the structural representation of this utility model nut.
Fig. 3 is the structural representation of this utility model aperture pressing plate.
Detailed description of the invention
As shown in Fig. 1, embodiment of the present utility model includes aperture pressing plate 5 and the anchor rod body 1 through aperture pressing plate 5, and the outer end of anchor rod body 1 is with nut 7.It is threaded on anchor rod body 1 and threaded has nut 4.Also it is installed with the spacer pin 3 being positioned at inside nut 7 on anchor rod body 1, is used for preventing nut 7 from coming off from inner side.Pad 6 it is provided with between aperture pressing plate 5 and nut 7.
Such as Fig. 2 and Fig. 3, the outside of described nut 4 offers from swollen steel band inner bayonet groove 41, and the inner side of described aperture pressing plate 5 offers from swollen steel band outer bayonet groove 51.
Still such as Fig. 1, embodiment of the present utility model also include offering several bar holes from swollen steel band 2, described anchor rod body 1 sequentially passes through several bar holes described and makes from swollen steel band 2 in homogeneous wave shape wave.Be positioned at described in swollen steel band inner bayonet groove 41 from the inner of swollen steel band 2, outer end is positioned at described in swollen steel band outer bayonet groove 51.
Described anchor rod body 1 is screw configuration in nut 4 stroke range, and remainder is smooth shaft, and described bar hole is smooth hole wall.When screwing described nut(cover) 7, nut 4 is displaced outwardly compressing from swollen steel band 2, moves and realize expanding outside sliding contacting mode between swollen steel band 2 bar hole and smooth shaft.
For permanent anchoring, it is not necessary to remove in the case of reclaiming, aperture pressing plate 5 offers pack hole 8.During use, first by self expansion rockbolt installation of the present utility model to anchor hole 9 and make it expand, then insert filling pipe from pack hole 8 and inject the materials such as expanding cement in anchor hole.
