Abstract
The utility model provides a modular dual balanced stock atress tray, includes flat pallet, slope tray, nut. The flat pallet shape is square or circular, and the angle of inclination that the one end of slope tray be half ball grooves, slope tray is for theta, and nut one end be the convex head, and half ball grooves of slope tray can match the gomphosis with the convex head of nut, is theta's slope tray according to the stock and the 1 selection angle of inclination of contained angle theta of enclosing the rock -wall face, | theta theta 1| value is best in 0~10 scope. During installing anchor, the flat pallet is slope tray, nut in country rock side, the outside in proper order. When the slope tray that has half ball grooves and the slope of the dual realization stock of the first nut of convex of this device are enclosed the rock -wall face and are arranged the stock atress the equilibrium, effectively solve the stock bevel and enclose the rock -wall face and arrange that problem, the especially stock angle of inclination that receives the unbalance loading lotus receives great unbalance loading lotus and is showing the problem that reduces the stock working property when great, and this device simple structure, processing convenience, use are convenient, have extensive suitability and practical value.
Description
Technical field
The utility model relates to a kind of combination double equilibrium rockbolt stress pallet, it is adaptable in Mineral Engineering, Geotechnical Engineering, especially
It is that anchor pole favours use when country rock wall is arranged.
Background technology
Suspension roof support is convenient and swift, effective, and in Mineral Engineering, Geotechnical Engineering, suspension roof support is the most universal.In order to more
Good reinforces country rock and the convenience of construction, and the widely used anchor pole in fillet region in tunnel favours country rock wall and arranges, anchor
Bar inclined peripheral rock wall surface arrange time, anchor nut contact unbalanced with pallet, this will cause anchor axial force not on axis, leads
The one side of cause anchor pole, by concentrated force, significantly reduces the service behaviour of anchor pole, has a strong impact on supporting effect.
When anchor pole favours country rock wall layout, use has the side that the pallet of female passage combines with male nut more
Method, but when oblique angles is slightly larger, anchor pole still can by more significant partial load, upper largely affect anchor pole mechanical property
The performance of energy.
Develop the anchor pole producing balanced forces pallet that applicability is more excellent, be remarkably improved the supporting effect that anchor pole inclined peripheral rock wall surface is arranged.
Summary of the invention
In place of the purpose of this utility model is intended to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, easy to use,
The pallet that applicability is strong, effective.
For achieving the above object, combination double of the present utility model equilibrium rockbolt stress pallet, including flat pallet, tilt tray,
Nut.
Described flat pallet is shaped as square or circle, flat pallet center is anchor pole passage.
One end of described tilt tray be hemispherical groove, the inclination angle of tilt tray be θ.
Described nut one end is convex head, can be chimeric with the hemispherical groove of tilt tray coupling.
When installing anchor pole, according to anchor pole and the angle theta of country rock wall1Selecting inclination angle is the tilt tray of θ, | θ-θ1| value is at 0～10 °
Scope is optimal, flat pallet in country rock side, outside be followed successively by tilt tray, nut.
Beneficial effect: owing to have employed technique scheme, double by the tilt tray and convex head nut with hemispherical groove
The method heavily coordinated, well realizes rockbolt stress equilibrium when anchor pole inclined peripheral rock wall surface is arranged, effectively solves anchor pole by partial load
And be substantially reduced the problem of suspension roof support performance, and this apparatus structure is simple, easy to process, easy to use, has and fits widely
By property and practical value.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is further described:
As shown in Figure 1,2,3, 4, a kind of double equilibrium rockbolt stress pallet, including flat pallet 4, tilt tray 1, nut
2.Described flat pallet 4 is anchor pole passage for circular, flat pallet 4 center.Described tilt tray 1 inclination angle is θ, inclination
The anchor pole passage 1b of pallet 1 has certain outer subtended angle, and the outer end of tilt tray 1 is the convex of hemispherical groove 1a and nut
Area of bed can mate chimeric.
As it is shown in figure 5, according to supporting design scheme, be arranged in the folder of the back 5 anchor pole 3 near portion of side 6 and top 5 plates
Angle θ1=45 °, then selecting the slanted angle θ of tilt tray 1 to be 35～55 ° and all can realize anchor pole producing balanced forces, θ is to be when 45 °
Optimum incline angle.Basic working procedure is holed for beating anchor pole 3, installs Anchor Agent, anchor pole 3, flat pallet 4, tilt tray 1, nut
2, use jumbolter to rotate and tighten anchor pole 3, to 2 two pretensions of nut, anchor pole 3 stress can be realized and be parallel to and anchor pole
3 central axis, prevent anchor pole 3 by partial load, utilize the supporting performance of anchor pole 3 to greatest extent.
Owing to have employed technique scheme, the utility model can well realize rockbolt stress when anchor pole inclined peripheral rock wall surface is arranged
Equalize, effectively prevent anchor pole to be substantially reduced the problem of suspension roof support performance by partial load, and this apparatus structure is simple, processing side
Just, easy to use, there is wide applicability and practical value.
