Abstract
A kind of anchor pole combination allows pressure device, including solid anchor pole, heavily stressed damping nut, lock washer, allows pressing spring, expansion tube, expander, pallet.There is a dual pressure device that allows the end of described anchor rod body, and described dual to allow pressure device be by allowing pressing spring, expansion tube and expander combine；It is described that to allow pressing spring be high-strength spring；Whole pressure device is allowed to be fixed in the middle of lock washer and pallet by termination point of anchor rod nut.The combination of this utility model anchor pole allows pressure device overcome in suspension roof support to be affected by country rock drastic deformation anchor pole elongation percentage is little and the shortcoming of shock resistance difference, efficiently solve simultaneously existing anchor pole by yielding property in pressure device can not high, make pressure device single and there is the problems such as " flattening " inefficacy.Allowing pressure device realize " the dual pressure that allows " effect by combination, during protection country rock large deformation, anchor pole is not destroyed, it is achieved that support system and the compatibility of deformation of country rock, has not only adapted to roadway deformation needs but also achieve the target of protection support system.
Description
Technical field
This utility model relates to the combination of a kind of anchor pole allows pressure device.Belong to ground anchorage and engineering support technical field, especially suitable
In coal mine roadway surrounding rock supporting.
Background technology
Roadway surrounding rock condition is the most complicated with the increase of coal mining depth.Under Mining in Deep-lying Conditions, due to the evil of geological environment
Changing, mining induced stress dramatically increases with tectonic stress, and roadway surrounding rock shows large deformation feature.When rock deformation exceedes anchor pole
Elongation, can cause the disrumpent feelings of anchor pole, even results in fall of ground, wall caving.Tunnel generally requires repeatedly safeguards and overhauls, peace
Full performance can not be guaranteed, and support cost strengthens, mine decline in benefits.Can apply high in advance should although currently used anchor pole has
The advantages such as power, intensity are high, span of control is big, but its elongation percentage and shock resistance are difficult to the drastic deformation of suitable for surrounding rock, reach
During certain pressure, anchor pole is disrumpent feelings, and safety of workers is caused serious threat.Existing anchor pole is by pressure device, when country rock large deformation,
Also existing and allow pressure device " flatten " phenomenon, then do not have the pressure effect that allows, it addition, existing, to allow pressure device be all single anti-
Control, flexible poor performance.This utility model provides the combination of a kind of anchor pole and allows pressure device, is adapted to large deformation by combination unit
Roadway surrounding rock, it is ensured that during country rock large deformation, anchor pole is not destroyed, it is achieved dual allow pressure effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of technology in existing suspension roof support, it is provided that a kind of anchor pole combination allows pressure device,
Adding the dual pressure device that allows in end on the basis of existing anchor pole, its feature is simple in construction, reasonable in design, strong adaptability
And it is easy to install.
To achieve these goals, specific embodiments of the present utility model is as follows: a kind of anchor pole combination allows pressure device, including anchor
Club shaft, has a dual pressure device that allows in the end of anchor rod body, described dual allow pressure device be by allow pressing spring, expansion tube and
Expander combines；It is described that to allow pressing spring be high-strength spring；Whole pressure device is allowed to be fixed on locking by termination point of anchor rod nut
In the middle of packing ring and pallet.
The dual pressing spring that allows allowing pressure device carries out prefabricated with expanding material according to anticipation stress size.
As preferred technical scheme, described expander is placed on anchor rod pallet board, and the power acted on anchor pole when surrouding rock deformation reaches
During to anchor pole load, expander makes expansion tube produce expansion, and internal diameter increases, so that anchor pole is gradually drawn into expansion tube.Play first
Heavily allow pressure effect.
As preferred technical scheme, described in allow pressing spring be placed between expander and lock washer.When expander enters expansion tube
When interior anchor pole load continues to increase, expander acts on and allows on pressing spring.Play second and heavily allow pressure effect.
Beneficial effects of the present invention: this allows pressure device play the support action of anchor pole to greatest extent, and when anchor pole is close to overload
Play pressure, the effect of protection anchor rod body of allowing.Allow pressure device between nut and pallet, have yielding property can and big elongation
Operating characteristic.Allow the effect of pressure device by anchor pole combination, enhance the intensity of roadway supporting system；By improving high strength anchor bar
Pretightning force and surface, tunnel supporting intensity, improve the supporting effect in tunnel, it is stable that tunnel achieves disposable supporting, no
Need to keep in repair and reinforce.Achieve the compatibility of deformation of support system and country rock, not only adapt to roadway deformation needs but also achieve protection
The target of protecting system.
Accompanying drawing explanation
For ease of explanation, this utility model is described in detail by following detailed description of the invention and accompanying drawing.
Fig. 1 is that the combination of this utility model anchor pole allows the overall structure schematic diagram of pressure device.
In figure, symbol description is as follows:
The heavily stressed damping nut of 1-；2-lock washer；3-allows pressing spring；4-expansion tube；5-expander；6-pallet；7-is solid
Anchor pole；8-Anchor Agent；
Detailed description of the invention
Combine refering to a kind of anchor pole shown in Fig. 1 and allow pressure device, including heavily stressed damping nut 1, lock washer 2, allow pressing spring
3, expansion tube 4, expander 5, pallet 6, solid anchor pole 7 and Anchor Agent 8.
Anchor pole 7 anchors into rock mass, rotates anchor rod stirring Anchor Agent 8, after Anchor Agent anchors, install successively pallet 6, expander 5,
Allow pressing spring 3, expansion tube 4, lock washer 2, heavily stressed damping nut 1 is finally installed.To be installed complete, when country rock is subject to
When tectonic stress field or stope disturbing influence country rock start to deform, anchor pole can gradually be stretched, the starting stage master of stretching
Expansion tube 4 to be leaned on bears pulling force, when expander 5 enters expansion tube 4 certain distance, allows pressing spring 3 start to play second-order
Section allow pressure effect.Under the whole common effect allowing pressure device, reach optimal yield supporting effect.
This utility model overcomes in suspension roof support is affected little lack poor with shock resistance of anchor pole elongation percentage by country rock drastic deformation
Point, efficiently solve simultaneously existing anchor pole by yielding property in pressure device can not high, make pressure device single and exist " flattening " lost efficacy
Etc. problem.Allowing pressure device realize " the dual pressure that allows " effect by combination, during protection country rock large deformation, anchor pole is not destroyed, and improves
The supporting effect in tunnel, it is achieved tunnel disposable supporting is stable.
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 and this,
Any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore,
Protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
