Description
Technical field
The utility model relates to a kind of anchor pole, especially a kind of High strength bolt suitable for coal mine shaft and drift supporting.
Background technique
The support pattern in Modern coal mines tunnel more and more uses suspension roof support.It is mostly used during suspension roof support
The anchor pole that rigidity is big, elongation percentage is low, it is uncoordinated with the deformation behaviour in tunnel, therefore when tunnel is in high stress and surrounding rock stability
It in the environment of difference is easy for that Bolt System is caused to fail, there are security risks, are unfavorable for the positive generation production activity in mine.For
It solves the above problems, many scholars propose targetedly flexible yield supporting technical measures, i.e., first primary using Bolt net and jet
Supporting realization controlledly allows pressure, suitably discharges after pressure, carries out secondary supporting after stabilization again, can effectively control lane
The deformation failure in road.But they there are still certain limitations, such as: (1) work progress project amount is big；(2) repair rate is high,
Increase the waste on unnecessary human and material resources.
Utility model content
The purpose of this utility model is to provide a kind of structure letter for existing mine anchor rod elongation percentage is low, makes pressure effect poor
It is single, easy to operate, elongation percentage is high, allows the good High strength bolt of pressure effect.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of novel high-strength anchor pole, including installing the body of rod in the borehole, one end that the body of rod is exposed to drilling is set
There are pallet, nut, the body of rod includes solid hopkinson bar, hollow stem and fixing end from top to bottom；Spring is equipped in the hollow stem；Institute
The diameter for stating hollow stem is greater than the diameter of solid hopkinson bar, and the upper end is equipped with the through-hole passed through for solid hopkinson bar, and fixing end is fixed in lower end；
It is solid hopkinson bar and fixing end that the upper and lower side of the spring, which is individually fixed in,.Solid hopkinson bar, hollow stem constitute " piston " structure, work as anchoring
When relative displacement occurs for rock stratum, spring has preferable extensibility, so that anchor pole, which has preferably to allow, presses effect, it can be effective
Reduce the generation of impact phenomenon.
Further, the upper and lower side of the spring is welded with solid hopkinson bar and fixing end respectively.
Further, the tensile strength and rigidity of the spring are greater than the body of rod, so that the body of rod during stretching will not be first
Be broken spring.
Further, the spring in the raw when, the length that the solid hopkinson bar is exposed to the part of hollow stem is
The 30%-40% of body of rod total length.
Further, the sum of its length and the length of solid hopkinson bar are greater than the length of hollow stem after the spring is compressed.
Further, its length is less than the length of hollow stem after the spring is stretched.
It is compared with the prior art compared with the beneficial effects of the utility model have:
(1) elongation percentage is high, makes pressure effect good.Solid hopkinson bar is connect with spring makes anchor pole have sufficient collapsing length, mentions significantly
High elongation percentage, so that anchor pole allows pressure effect to be effectively improved；
(2) reduce project amount, reduce repair rate.Supporting by the way of settling at one go, do not need carry out secondary supporting or
Person's secondary supporting number is less, greatly reduces repair project amount, saves the resources such as man power and material.
(3) structure is simple, practical, easy to operate, has a extensive future.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Figure label: 1, nut, 2, pallet, 3, fixing end, 4, spring, 5, hollow stem, 6, drilling, 7, solid hopkinson bar.
Specific embodiment
Further explanation is done to the present invention with reference to the accompanying drawing.
As shown in Figure 1, the utility model includes the body of rod being mounted in drilling 6, one end that the body of rod is exposed to drilling 6 is equipped with
Pallet 2, nut 1.The body of rod includes solid hopkinson bar 7, hollow stem 5 and fixing end 3 from top to bottom.Spring 4 is equipped in hollow stem 5；It is hollow
The diameter of bar 5 is greater than the diameter of solid hopkinson bar 7, and the upper end is equipped with the through-hole passed through for solid hopkinson bar 7, and fixing end 3 is fixed in lower end；Bullet
The upper and lower side of spring 4 is welded with the lower end of solid hopkinson bar 7 and the upper end of fixing end 3 respectively.Solid hopkinson bar 7, hollow stem 5 form " piston " knot
Structure, solid hopkinson bar 7 can be slided up and down relative to through-hole.When drill 6 around rock stratum occur relative displacement when, can stretch or
Person's compressed spring 4, at this moment will improve the elongation percentage of anchor pole, to advantageously reduce the impact harm in tunnel.
Spring 4 in the raw when, the length that solid hopkinson bar 7 is exposed to the part of hollow stem 5 is body of rod total length
30%-40%, when relative displacement occurs for the length too short rock stratum that will lead to around drilling 6, the pulling force of generation cannot be acted on
Onto solid hopkinson bar 7.
The sum of its length and the length of solid hopkinson bar 7 are greater than the length of hollow stem 5 after spring 4 is compressed, and prevent solid hopkinson bar 7
It is fully retracted in hollow stem 5.
Its length is less than the length of hollow stem 5 after spring 4 is stretched, and solid hopkinson bar 7 is prevented to be drawn out hollow stem 5 completely.
The anchoring process of anchor pole provided by the utility model, includes the following steps:
A. drilling 6 is opened up at the top of mine laneway or portion, side；
B. Anchor Agent is filled into the drilling 6；
C. anchor pole is advanced into drilling 6, external pallet 2 and nut 1, which pre-tighten, makes up to suitable pretightning force.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations to the greatest extent
Pipe the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that its according to
It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced
It changes and these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Range.
