Abstract
It the utility model is related to a kind of Novel threaded anchor pole hangnail device, it is made of threaded anchor rod, nut, anchor pole hangnail, brute spring, shaft, anchor pole hangnail is equipped with outside nut, nut is connected with anchor pole hangnail by shaft, brute spring one end is connected with nut, one end is connected with anchor pole hangnail, in the middle part of nut driving to threaded anchor rod.The utility model has the characteristics that：After in threaded anchor rod insertion drilling, anchor pole hangnail prevents anchor pole from producing relative displacement with rock mass inner wall under the action of brute spring, and anchor pole hangnail is placed on nut by the device, and nut is fixed on threaded anchor rod by screwing, easy to operate, easy to make.Meanwhile effectively will prevent anchor pole from ejecting in the region that bump easily occurs, improve the safety of construction personnel.
Description
Technical field
Bolt support technology field is the utility model is related to, is specifically a kind of improved Novel threaded anchor pole hangnail device.
Background technology
Suspension roof support is the important support pattern controlled in coal mine roadway surrouding rock deformation.Coal mine support technique is predominantly first beaten
Anchor pole, is then inserted into by hole, and last slip casting is fixed.As slip casting changes with the passage property of time, anchor pole easily occurs with rock mass
Relative displacement, anchoring effect will gradually die down, and influence the supporting effect of anchor pole.Therefore, such a technique causes suspension roof support to stablize
Property is poor, it is impossible to permanently effective deformation controlling for rock surrounding gateways.As surrounding rock stability control effect is poor, surrouding rock stress distribution will be changed
Situation, directly affects the safe and efficient production of working face.
The content of the invention
This is insufficient in order to overcome threaded anchor rod that relative displacement easily occurs with rock mass for the utility model, there is provided a kind of novel spiral
Line anchor pole hangnail device.
The utility model is realized using following scheme：A kind of Novel threaded anchor pole hangnail device, by threaded anchor rod, spiral shell
Mother, anchor pole hangnail, brute spring, shaft composition, nut outside are equipped with anchor pole hangnail, and nut passes through shaft phase with anchor pole hangnail
Even, brute spring one end is connected with nut, and one end is connected with anchor pole hangnail, in the middle part of nut driving to threaded anchor rod.
The nut is connected with threaded anchor rod by screw thread.
The advantage of the utility model is：After in threaded anchor rod insertion drilling, effect of the anchor pole hangnail in brute spring
Under prevent anchor pole and rock mass inner wall from producing relative displacement, and anchor pole hangnail is placed on nut by the device, and nut is solid by screwing
It is easy to operate due to threaded anchor rod, it is easy to make.Meanwhile it will effectively prevent anchor pole bullet in the region that bump easily occurs
Go out, improve the safety of construction personnel.
Brief description of the drawings
Fig. 1 is status architecture schematic diagram of the utility model anchor pole in palisades.
Fig. 2 is the utility model structure diagram.
Embodiment
In order to make it easy to understand, the utility model is further retouched by an instantiation with reference to attached drawing herein
State, it should be understood that the scope of protection of the utility model from instantiation limit.
As shown in Figure 1, 2, a kind of Novel threaded anchor pole hangnail device, by shaft 1, brute spring 2, nut 3, anchor pole hangnail
4th, threaded anchor rod 5 forms, and the outside of nut 3 is equipped with anchor pole hangnail 4, and anchor pole hangnail 4 is connected by shaft 1 with nut 3, brute spring
2 one end are connected with nut 3, and one end is connected with anchor pole hangnail 4, and nut 3 is threaded to the middle part of threaded anchor rod 5, nut 3 and threaded anchor rod 5
It is connected by screw thread.
A kind of Novel threaded anchor pole hangnail device that above instantiation is mentioned, when specifically used, is pressed in country rock 7 first
Drill according to supporting scheme, 6 diameters of drilling should be slightly bigger than 5 outside diameter of threaded anchor rod.By shaft 1 by anchor pole hangnail 4 and nut
3 connections, 2 one end of brute spring are connected with nut 3, one end is connected with anchor pole hangnail 4.The nut 3 of anchor pole hangnail 4 will be installed
The middle part of threaded anchor rod 5 is threaded to, according to arrangement and method for construction, by 5 body of rod of threaded anchor rod insertion drilling 6, then carries out injecting treatment,
Finally apply certain pretightning force, 5 body of rod of threaded anchor rod and country rock 7 will produce relative displacement, and anchor pole hangnail 4 is in strength bullet at this time
Open and be pierced into rock mass under the action of spring 2, come into full contact with rock mass and larger withdrawal resistance is provided, make threaded anchor rod 5 and country rock
7 inner walls produce close contact, step up bolt pretension.With the change of anchoring time and country rock mining induced stress, 5 He of threaded anchor rod
Country rock 7 will produce relative displacement, and at this time, anchor pole hangnail 4 will produce close contact with country rock 7, reach effective control tunnel and enclose
Rock deforms, and has effectively ensured bolt pretension, is finally reached effectively control deformation of the surrounding rock in tunnel purpose.
