Description
Technical field
The present invention relates to roadway support pallet fields, are specially a kind of high-strength multifunctional composite pallet.
Background technology
For colliery tunnel support, with deep increase is adopted, more and more mines enter deep mining, and " three is high
The problem of one disturbance ", is on the rise.There is impact phenomenon and rheological behavior in roadway surrounding rock.For roadway support anchor pole and
The pressure that anchor cable is born is increasing.But due to material and support holder structure design it is unreasonable, in actual use,
It is a large amount of anchor pole and anchor cable pallet pressure break, tear occur, perforate, turn over, the destructions problem such as rake angle.For this phenomenon, pallet
Thickness 12mm, material till now increased by original 5mm change to Q400 steel from Q235 steel, but still without very big lid
On.Then tablet pallet is gradually substituted, and instead has round tray, the square pallet with dome.With carrying for material
The high and use with the structures pallet such as arc top, solves the above problem within past a period of time.It is but deep with adopting
Increase, breakoff phenomenon occurs again in above-mentioned pallet.Increase pallet thickness and raising material simply can greatly improve production cost
And difficulty of processing, this is clearly unpractical.Especially current colliery industry is depressed, under the form of deficiency in economic performance, is protecting
On the basis of card solves anchor pole, anchor cable pallet destroys, cost is reduced, simplified processing technology is even more important.It is prior existing
Pallet can only provide the load along anchor pole axial direction, this is extremely unfavorable for the diffusion of anchor stress.It therefore, can only be by improving anchor pole
Density realizes surrouding rock stress arch.
Set forth herein a kind of high-strength multifunctional composite pallet, in the case where not increasing pallet thickness and improving material,
Change pallet force structure and using solve by way of composite construction pallet above-mentioned in bolt and cable anchor supporting destroy and
Stress spread problem, and it is at low cost, processing technology is simple.In existing disclosed document, also fail to obtain related supporting skill
The report of art.

One side be installed with angle hook, wherein angle hook is located at one side of the tray main body away from country rock close to the one side of stress spread circle
Surface is installed with reinforcing rib, and the center of the tray main body offers through hole, the inside plugged and fixed of the through hole
There is anchor pole, wherein one end of the anchor pole is reached through through hole inside country rock, one side of the tray main body away from country rock is fixed
Stiffening ring is installed, is fixed by socket in the middle part of the stiffening ring in the outside of anchor pole, the surface of the anchor pole is away from stiffening ring
Multiple iron gaskets are nested and fixed in one side, are located between two of which iron gasket on the outside of anchor pole and plastic spacer is nested and fixed,
The surface location that one side of the iron gasket away from plastic spacer is located at anchor pole is screwed and has nut.
Preferably, the tray body, stress spread circle, reinforcing rib, angle hook and through hole are an integral molding structure, described
The surface of stress spread circle is provided with protrusion, and protrusion direction is towards country rock one side.
Preferably, the stiffening ring is butterfly structure, and is fixedly connected with stress spread circle, wherein stiffening ring butterfly structure
Outer convex direction is with the protrusion direction of stress spread circle on the contrary, the edge of the stiffening ring is equal with the edge of stress spread circle.
Preferably, the angle hook is located at the corner of tray main body, and towards country rock curving.
Preferably, the quantity of the reinforcing rib is four, and is symmetrical arranged on surface of the tray main body away from country rock one side.
Compared with prior art, the beneficial effects of the invention are as follows：The high-strength multifunctional composite pallet has following excellent
Point and good effect：
(1) compared with traditional tray, stress spread circle of the invention can coordinate with anchor pole, anchor cable drilling, except along anchor
Bar, anchor cable are axially provided outside stress, can also be to providing stress to anchor pole, anchor cable peripheral rock.Increase between anchor pole, anchor cable
Compression area is conducive to improve surrounding rock stability.(2) reinforcing rib of the invention can improve the intensity of four angular zone of pallet, subtract
Few phenomena such as even eliminating the destructions such as tray turnover labeling rake angle.
(3) angle of the invention hooks and can catch on and tense the metal mesh of auxiliary shoring, improves the effect of auxiliary shoring.
(4) cooperation of stiffening ring and stress spread circle of the invention, on the basis of stress spread is realized, improves pallet
Intensity solves the problems such as pallet is pulled through, torn, and improves the effect of supporting.
(5) the stress spread circle in tray body of the invention, reinforcing rib, angle hook, through hole are once made of one block of steel plate,
In the case where not increasing pallet thickness and improving material, the high intensity of pallet is realized by adding new structure, is dropped significantly
Low cost and difficulty of processing.
