Abstract

The utility model discloses a kind of aligning by pressure type anchor pole, the pallet comprising bolt body and be arranged in bolt body and nut, aligning is provided with by pressure pipe between pallet and nut, aligning protrudes by one end of pressure pipe the pressure ring that allows forming drum organization to outer arcuate, the other end is the ball pad that outside is provided with annular flange flange, the outside of ball pad is fixedly connected with pallet, allows between pressure ring and nut and is provided with nylon spacer.The utility model, by being provided with aligning by pressure pipe between pallet and nut, when country rock load is larger than certain value, slow distortion will be there is in aligning by pressure pipe, form certain allowing and press space, realize aligning and allow pressure, thus the strain energy of distortion making country rock huge is necessarily discharged, country rock enters metastable state, anchor pole recovers again the performance of rigid protection, achieves soft with firm combination, effectively controls surrounding rock failure distortion, and prevent the single pressure ring center that allows that situation about offseting easily occurs, there is very high practical value.

Description

Aligning is by pressure type anchor pole
Technical field
The utility model relates to anchor pole, is specifically related to aligning by pressure type anchor pole.
Background technology
Anchor pole is a kind of supporting apparatus important in mine working operation, at present, conventional anchor pole comprises shaft-like anchor rod body, anchor rod body is provided with pallet and fastens nut, and employing allows pressure ring realize allowing pressure, but at supporting later stage anchor pole, slow distortion is easily occurred for high stress tunnel country rock, anchor pole material is easy to cause supporting to lose efficacy due to poor ductility, when helping the surrounding rock supporting of the bolt support of angle or tunnel surface irregularity for roof and floor and two in addition, there is the single pressure ring center that allows and situation about offseting easily occur in existing anchor pole, affect supporting effect, security incident can be caused time serious.
Utility model content
Technical problem to be solved in the utility model is that existing anchor pole adopts the single pressure ring center that allows that the problem offset easily occurs.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of aligning by pressure type anchor pole, the pallet comprising bolt body and be arranged in described bolt body and nut, aligning is provided with by pressure pipe between described pallet and described nut, described aligning protrudes by one end of pressure pipe the pressure ring that allows forming drum organization to outer arcuate, the other end is the ball pad that outside is provided with annular flange flange, the outside of described ball pad is fixedly connected with described pallet, described in allow between pressure ring and described nut and be provided with nylon spacer.
In such scheme, described aligning has an axially extending bore by pressure pipe, and the diameter of described axially extending bore is greater than the diameter of described bolt body.
In such scheme, described in allow pressure ring and described ball pad one-body molded.
In such scheme, described pallet inner hollow, outer end is protruding with the pallet outer perpendicular with described bolt body.
In such scheme, described aligning adopts elastomeric material by pressure pipe.
The utility model, by being provided with aligning by pressure pipe between pallet and nut, when country rock load is larger than certain value, slow distortion will be there is in aligning by pressure pipe, form certain allowing and press space, realize aligning and allow pressure, thus the strain energy of distortion making country rock huge is necessarily discharged, country rock enters metastable state, anchor pole recovers again the performance of rigid protection, achieves soft with firm combination, effectively controls surrounding rock failure distortion, and prevent the single pressure ring center that allows that situation about offseting easily occurs, there is very high practical value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of aligning by pressure type anchor pole, the pallet 20 comprising bolt body 10 and be arranged in described bolt body 10 and nut 50, bolt body 10 is the full thread structure adopting glass fiber compression molding, pallet 20 and nut 50 are set in bolt body 10, pallet 20 inner hollow, outer end is protruding with the pallet outer 21 perpendicular with bolt body 10, towards the free end of bolt body 10, (in Fig. 1, left end is free end to pallet outer 21 opening end, right-hand member is anchored end), the aligning performance that the structure of inner hollow makes pallet 20 can keep good.
Be provided with aligning between pallet 20 and nut 50 by pressure pipe, aligning has an axially extending bore by pressure pipe, and the diameter of axially extending bore is greater than the diameter of bolt body 10, conveniently be sleeved in bolt body 10, in the utility model, aligning adopts elastomeric material by pressure pipe, to reach the effect of compensator or trimmer pressure.When country rock load is larger than certain value, will there is slow distortion by pressure pipe in aligning, forms certain pressure space that allows, and realizes aligning and allow pressure.Aligning by pressure pipe one end to outer arcuate protrude form drum organization allow pressure ring 40, the other end is the ball pad 30 that outside is provided with annular flange flange, allows pressure ring 40 and ball pad 30 adopt one-body molded obtaining, Stability Analysis of Structures.
Pallet 20 is fixed on the annular flange portion of ball pad 30, pressure ring 40 is allowed to possess certain pressure energy power that allows, pressure transfer can be realized when tunnel sidewall pressurized, transferring to by pressure allows on pressure ring 40, by allowing the axial deformation absorption pressure of pressure ring 40, prevent from bolt body 10 from breaking to split, the telescoping structure of ball pad 30 adds the size and anti-extrusion ability that allow pressure ring 40 on bolt body 10 axial direction simultaneously, after tunnel is excavated, can effectively prevent deformation of the surrounding rock in tunnel from destroying, keep maximum and utilize space.Allow between pressure ring 40 and nut 50 and be provided with nylon spacer 60, nylon spacer 60 make to allow between pressure ring 40 and nut 50 be connected firmly, favorable sealing property and there is certain buffering resistance to pressure.
The utility model, by being provided with aligning by pressure pipe between pallet and nut, when country rock load is larger than certain value, slow distortion will be there is in aligning by pressure pipe, form certain allowing and press space, realize aligning and allow pressure, thus the strain energy of distortion making country rock huge is necessarily discharged, country rock enters metastable state, anchor pole recovers again the performance of rigid protection, achieves soft with firm combination, effectively controls surrounding rock failure distortion, and prevent the single pressure ring center that allows that situation about offseting easily occurs, there is very high practical value.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
