Description
Technical field
The utility model relates to mine or engineering reinforcement technical field, refers to the tight latch fitting of a kind of non-metallic rock especially.
Background technology
Anchor pole is the element of roadway support in contemporary colliery, it by the surrounding rock consolidation in tunnel together, make country rock self supporting self, can also be used in engineering, to side slope, tunnel, dam body carries out main body reinforcing, its operating principle is: open a hole (degree of depth is by designing requirement) by needing subdrilling on the work plane of anchoring, process in clean metapore and fill in Anchor Agent, then being rotated by anchor pole pushes in hole, Anchor Agent and anchor pole, inner hole wall close adhesion, after cured the pallet of a central punch is enclosed within anchor pole outer end (anchor pole has external screw thread) in hole, then nut is screwed in pallet outer end (nut has internal thread), until tighten stressed till.
The locking effect of pallet and nut, extremely important for anchor pole.Existing anchor pole pallet and nut, mainly contain two kinds: one is the cylindrical pallet of endoporus, is equipped with flat nut; The pallet of another kind to be endoporus be wedge shape, be equipped with wedge nut, some is in order to strengthen bearing capacity, and wedge nut middle-end also establishes a stop step.Use at present mostly for endoporus is wedge shape, pallet is equipped with the locking member of wedge nut as anchor pole, but in use there is following shortcoming in this structure:
Although 1, wedge-shaped design strengthens coupling mechanism force, pallet is stressed constantly outwards to be pushed afterwards, easily causes wedge nut to be cracked by pallet;
2, stop that step design is unreasonable, 90 °, the large sky of junction angle of step and sphenoid is obtuse angle, and the junction of step and six square nuts is right-angle design, and such design is very easily burst apart after step is under pressure, and can not give full play to the effect stopping pressure.
Utility model content
The utility model proposes the tight latch fitting of a kind of non-metallic rock, for solving the problem in background technology.
The technical solution of the utility model is achieved in that
The tight latch fitting of a kind of non-metallic rock, comprises matching used nut and pallet, nut comprise set gradually six square nuts, stop step, bossy body and wedge shape embedded body, wedge shape embedded body is provided with fluting; Pallet comprises tray body, is provided with the wedge shape endoporus mated with wedge shape embedded body in tray body, and the top of wedge shape endoporus is provided with the recessed body mated with bossy body.
Preferably, nut is also provided with stress reinforcement, stress reinforcement is arranged on six square nuts and stops between step.
Preferably, stress reinforcement comprises coniform stress reinforcement.
Preferably, six square nuts, stress reinforcement, stop step and bossy body are integral type structure.
Preferably, bossy body comprises the one of hemispherical bossy body and pyramidal projections.
Preferably, recessed body comprises hemispherical and is recessed into the one that body and taper are recessed into body.
The tight latch fitting of non-metallic rock that the present invention proposes, by arranging bossy body on nut, pallet arranges recessed body, achieves combining closely of nut and pallet, can dispersive pressure effectively, can play a protective role again to stop.In addition, stopping that the outer end of step is provided with stress reinforcement, effectively can support stop step, enhance the supporting capacity of nut, improve stability and the safety of engineering or mine anchor rod.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1-Fig. 4 jointly shown in: the tight latch fitting of a kind of non-metallic rock, comprise matching used nut 1 and pallet 2, nut 1 comprise set gradually six square nuts 16, stop step 14, bossy body 13 and wedge shape embedded body 11, wedge shape embedded body 11 is provided with fluting 12; Pallet 2 comprises tray body 23, is provided with the wedge shape endoporus 22 mated with wedge shape embedded body 11 in tray body 23, and the top of wedge shape endoporus 22 is provided with the recessed body 21 mated with bossy body 13.
As Fig. 5 and Fig. 6 jointly shown in: when use, pallet 2 is nested on anchor pole 3, anchor pole 3 fixed tray 2 is inserted in afterwards with nut 1, wedge shape embedded body 11 on nut 1 is embedded in the wedge shape endoporus 22 on pallet 2, due to pressure effect, tray body 23 outwards moves gradually and wedge shape embedded body 11 and wedge shape endoporus 22 is combined closely, and then makes fluting 12 progressively hold anchor pole 3 tightly; When pressure strengthens further, bossy body 13 on nut 1 can embed in the recessed body 21 on pallet 2 gradually, and pressure is distributed on pallet 2 by bossy body 13, and tray body 23 is close to stop step 14 simultaneously, stop that step 14 moves, in order to avoid nut 1 bursts apart after can effectively stopping tray body 23.The tight latch fitting of non-metallic rock that the present invention proposes; by arranging bossy body 13 on nut 1; pallet 2 arranges recessed body 21; achieve combining closely of nut 1 and pallet 2; can dispersive pressure effectively; can play a protective role to stop step 14 again, improve stability and the safety of anchor pole 3.
As the preferred technical scheme of one, an embodiment more of the present utility model, nut 1 is also provided with stress reinforcement 15, and stress reinforcement 15 is arranged on six square nuts 16 and stops between step 14.
As the preferred technical scheme of one, another embodiment of the present utility model, stress reinforcement 15 comprises coniform stress reinforcement.
The utility model patent is also provided with stress reinforcement 15 between six square nuts 16 and stop step 14, for strengthening the support to stopping step 14, in order to avoid pressure excessive causing stops that step 14 bursts apart, further increases safety and the stability of anchor pole 3; Stress reinforcement 15 comprises coniform stress reinforcement, and certain stress reinforcement 15 also can be other shapes, such as triangular pyramidal, corner taper etc., as long as can play a supporting role to stop step 14.
As the preferred technical scheme of one, another embodiment of the present utility model, six square nuts 16, stress reinforcement 15, stop step 14 and bossy body 13 are integral type structure.
As the preferred technical scheme of one, an embodiment more of the present utility model, bossy body 13 comprises the one of hemispherical bossy body and pyramidal projections.
As the preferred technical scheme of one, another embodiment of the present utility model, recessed body 21 comprises hemispherical and is recessed into the one that body and taper are recessed into body.
Bossy body 13 matches each other with the shape of recessed body 21, preferred hemispherical or taper.Certainly, other shapes are also passable, as long as can realize combining closely of bossy body 13 and recessed body 21.
These three kinds of parts of anchor pole 3, pallet 2 and nut 1 are closely combined, the various power such as coupling mechanism force, dispersion force, barrier force and support force are fully disperseed by the tight latch fitting of the non-metallic rock that the utility model proposes.Compared with prior art, the non-metallic rock that the utility model proposes pressure that tight latch fitting bears improves at least 20%, considerably increases stability and the safety of engineering or mining anchoring operation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
