Description
Technical field
A kind of multistage pressure-relieving achor bar of the utility model, belongs to underground engineering support engineering device technique field.
Background technique
In the supporting of underground passage, suspension roof support is a very important component in support system, mine field with
The increase year by year of mining depth, crustal stress also significantly increase, the surrouding rock stress in tunnel also increases, and in deep tunnel, country rock
Address changes, and soft rock phenomenon occur in some places, and thus formation roadway deformation amount is big, and the deformation duration is long, high current
Phenomena such as deformation.
Currently, have with yielding property can anchor pole, function and act on part have allow pressure operating condition under play it is certain
The effect of, but large deformation, high stress tunnel operating condition under, traditional pressure-relieving achor bar is not able to satisfy its effect, and elongation percentage is not
Foot, buffering is small, flexible poor, it is difficult to which that the stability for maintaining country rock cannot achieve expected effect, cannot effectively be generalized to engineering
In practice.
Utility model content
The utility model overcomes the shortcomings of the prior art, provide one kind can multistage allow pressure, buffering is big, flexible
It is good, the high pressure-relieving achor bar of stability.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of multistage pressure-relieving achor bar, including
Anchor bar body, anchor bar body be successively set with from bottom to top pallet, allow pressure ring assembly, allow pressure damper assembly and nut, in pallet and allow
It is provided between pressure ring assembly and allows pressing spring, pressing spring is allowed to be sleeved on anchor bar body, the nut, which can be adjusted, makes to allow pressure drag Buddhist nun
Component, allow pressure ring assembly, allow pressing spring formed multistage allow pressure cushioning control reach allow pressure distance；
Described allows pressure ring assembly to be elastic hollow spherical structure；
Described allows pressure damper assembly to be lantern shape, including multiple blade profile elastic slices and the upper fixed ring being set on the body of rod
With lower fixed ring, blade profile elastic slice one end is connected with upper fixed ring, and the other end is connected with lower fixed ring.
It is described to make pressure ring assembly bowl-shape for back-off, allow the edge of pressure ring assembly to be provided with the flanging being in close contact with pallet.
It is described to allow the surface area of pressure ring assembly for the 50%-100% of pallet table area.
The utility model have the advantages that compared with prior art by allow pressure drag damping member formed first-level buffer,
Multi-buffer is formed by pallet and spring, makes that pressure ring section is allowed to reach ideal state, pressure drag damping member is allowed to be lantern shape, itself
Has the function of certain pressure that allows, inner hollow and spring cooperation can make to make pressure function more powerful, while use allows pressure drag Buddhist nun
Part can form multiple-harmonic and allow pressure function, and spring allows pressure drag damping member to allow the pressure limit, so at work, can be set and allow
The greatest limit of pressure, and then protect anchor pole from destroying.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure 1 be anchor bar body, 2 be pallet, 3 for allow pressing spring, 4 for allow pressure ring assembly, 5 for allow pressure damper assembly, 6 be spiral shell
It is female.
Specific embodiment
As shown in Figure 1, a kind of multistage pressure-relieving achor bar of the utility model, including anchor bar body 1, anchor bar body 1 is from bottom to top successively
Be set with pallet 2, allow pressure ring assembly 4, allow pressure damper assembly 5 and nut 6, in pallet 2 and allow between pressure ring assembly 4 be provided with and allow
Pressing spring 3 allows pressing spring 3 to be sleeved on anchor bar body 1, the nut 6 can adjust make to allow pressure damper assembly 5, allow pressure ring assembly
4, allow pressing spring 3 formed multistage allow pressure cushioning control reach allow pressure distance；
Described allows pressure ring assembly 4 to be elastic hollow spherical structure；
Described allows pressure damper assembly 5 to be lantern shape, including multiple blade profile elastic slices and the upper fixation being set on the body of rod
Ring and lower fixed ring, blade profile elastic slice one end are connected with upper fixed ring, and the other end is connected with lower fixed ring.
It is described to make pressure ring assembly 4 bowl-shape for back-off, allow the edge of pressure ring assembly 4 to be provided with the folding being in close contact with pallet 2
Side.
It is described to allow the surface area of pressure ring assembly 4 for the 50%-100% of 2 surface area of pallet.
Make pressure slow when the utility model is used, making damping that casting die, pallet, spring be allowed to form multistage by the adjusting of nut
Punching reaches ideal distance eventually by limit to control, tension is reached defined pretightning force when installation in this way, is led to
Overdamp allows casting die, pallet, spring release multistage that pressure is allowed to buffer, and reaches the ideal state of operating condition, makes pressure flexible big, adaptive
Ying Xingqiang, using multiple elastic slices, inherently has the function of certain pressure that allows since damping allows casting die to be lantern shape, can be with shape
Pressure function is allowed at multiple-harmonic, and protection anchor pole is from destroying.
The utility model, which is provided with to allow, presses locating part, can prevent to allow pressure ring section from too greatly, can protect anchor pole from broken
It is bad.
The supporting with underground passage can be widely applied in the utility model, and versatility is preferable, meet various roadway deformation amounts
Greatly, the place for phenomena such as deformation time is long, and high current deforms.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of various changes can be made.
