Abstract
The utility model discloses a diversely let die mould stock tray, including ring tray, drum collet, arcuation elastic steel plate and round tray. It has the reservation through -hole to open in the middle of the round tray, and round tray upper portion is protruding, has on average opened eight quad slits in round tray edge, and the drum collet is fixed at the positive center in round tray's lower part, and average opening has eight circular through -holes on the ring tray, and arcuation elastic steel plate one end is fixed on the round tray edge, and the other end is fixed the ring tray on, make ring tray and round tray have certain discrepancy in elevation. When the tunnel country rock took place great deformations, the drum collet can be impressed in the country rock of tunnel gradually, and along with after the drum collet gets into the tunnel country rock, atress direction that the ring tray can self -adaptation surrouding rock deformation takes place crooked a part of pressure that comes from tunnel country rock multi -azimuth of realizing letting through arcuation elastic steel plate to guarantee the complete of stock, improve country rock control effect.
Description
Technical field
The utility model relates to a kind of coal mine underground exploitation engineering supporting anchor rod system used, especially a kind of multi-faceted die mould anchor pole pallet that allows.
Background technology
Bolt supporting is supporting mode the most common in coal mine underground exploitation engineering, and as a kind of active support mode, its supporting effect is good, and cost is low, has become the main support form of China's coal-mine roadway support. At present, the further investigation of bolt support mechanism being shown according to China, in underground works bolt supporting process, pallet is very important parts in bolt supporting system. Anchor pole pallet provides anchor support force by extruding roadway surrounding rock, especially plays a role immediately after anchor pole applies preliminary tension, constraint country rock distortion. When multi-faceted distortion occurs roadway surrounding rock, the pallet being fastened on roadway surrounding rock can be extruded, cause pallet distortion, destruction even to make anchor pole rupture, cause Anchoring Strength of Rock Bolts to reduce, even make bolt supporting lose efficacy. The anchor pole fracture that this kind causes because being out of shape causes because of tray design existing defects often, at roadway surrounding rock generation moderate finite deformation and when exceeding the supporting intensity of anchor pole and pallet, part country rock can be allowed to be out of shape by pallet, release country rock is to the pressure of anchor pole and pallet, so anchor pole pallet not only to be had high strength, also should have higher yielding property energy.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of multi-faceted die mould anchor pole pallet that allows, and when the distortion of relatively hard intensity occurs in roadway surrounding rock, this anchor pole pallet can carry out allowing pressure with the direction of country rock distortion, thus solve high-ground stress to the destruction problem of anchor pole, effective deformation controlling for rock surrounding gateways.
The utility model is solve the problems of the technologies described above the technical scheme adopted:
This multi-faceted die mould anchor pole pallet that allows, comprises annulus pallet, cylinder collet, arc shape spring steel plate and round tray. Reserved through hole is had in the middle of described round tray, round tray upper lobes, eight square holes are on average had in round tray edge, described cylinder collet is fixed on the center, bottom of round tray, described annulus pallet on average has eight circular through holes, described arc shape spring steel plate one end is fixed on round tray edge, and the other end is fixed on described annulus pallet, makes annulus pallet and round tray have certain height difference.
This multi-faceted die mould anchor pole pallet that allows, described annulus pallet, round tray are made by steel, and the rigidity of annulus pallet is less than the rigidity of round tray.
This multi-faceted die mould anchor pole pallet that allows, described cylinder collet is also made up of steel, and the rigidity of cylinder collet is less than the rigidity of round tray, and cylinder collet top is fixed on below round tray, the bottom of cylinder collet is widened, and bottom of cylinder width is less than the width of annulus pallet.
This multi-faceted die mould anchor pole pallet that allows, described arc shape spring steel plate is by high strength, and the steel of high tenacity are made, it is possible to bending and can bear high pressure, the rigidity of arc shape spring steel plate is less than the rigidity of round tray.
The beneficial effects of the utility model:
Basis is multi-faceted makes die mould anchor pole pallet suitable for surrounding rock distortion ability strong, along with the distortion of roadway surrounding rock, annulus pallet and cylinder collet are applied pressure by country rock, the effect be out of shape by country rock by cylinder collet gradually enters in country rock body and annulus pallet realizes allowing pressure by the bending of arc shape spring steel plate, ensure the complete of anchor pole and anchor pole tray body, it is to increase Surrounding Rock Control effect.
Basis is multi-faceted makes die mould anchor pole support holder structure simple, and cost is low, is easy to install, and suitability is strong.

Wherein, the 1. circular square through hole of through hole 9. of annulus pallet 2. cylinder collet 3. arc shape spring steel plate 4. round tray 5. set screw nut 6. anchor nut 7. anchor pole 8.
Embodiment
Below in conjunction with drawings and Examples, the utility model is illustrated further:
As shown in Figure 1, Figure 3, this multi-faceted die mould anchor pole pallet that allows, comprises annulus pallet 1, cylinder collet 2, arc shape spring steel plate 3 and round tray 4.
Reserved through hole 8 is had in the middle of described round tray 4, round tray 4 upper lobes, eight square through holes 9 are on average had in round tray 4 edge, described cylinder collet 2 is fixed on the center, bottom of round tray 4, described annulus pallet 1 on average has eight through holes, described arc shape spring steel plate 3 one end is fixed on the edge of round tray 4 through square through hole 9, the other end of arc shape spring steel plate 3 is fixed on annulus pallet 1 by set screw nut 5, makes annulus pallet 1 and round tray 4 have certain discrepancy in elevation.
Described annulus pallet 4, arc shape spring steel plate 3 and round tray 4 are made by steel, and the rigidity of annulus pallet 1 is less than the rigidity of arc shape spring steel plate 3, and the rigidity of arc shape spring steel plate 3 is all less than the rigidity of round tray 4.
Described cylinder collet 2 is also made up of steel, and the rigidity of cylinder collet 2 is less than the rigidity of round tray 4, and the top of cylinder collet 2 is fixed on the lower section of round tray 4, and the bottom of cylinder collet 2 is widened, and bottom of cylinder width is less than the width of annulus pallet 4.
As shown in Figure 3, when roadway surrounding rock generation moderate finite deformation, cylinder collet 2 can be pressed in roadway surrounding rock gradually, after cylinder collet 2 enters roadway surrounding rock, the Impact direction of annulus pallet 1 meeting self-adaptation country rock distortion, bent by arc shape spring steel plate 3 and realize allowing a part of pressure multi-faceted from roadway surrounding rock, thus ensure the complete of anchor pole 7, it is to increase Surrounding Rock Control effect.
Certainly; more than illustrate it is only better embodiment of the present utility model; the utility model is not limited to above-described embodiment; should be noted that; any people being familiar with this area is under the guidance of this specification sheets; equivalent replacement, obviously the deformation form made, all drops in the essential scope of this specification sheets, ought to be subject to protection of the present utility model.
