Abstract
The utility model discloses an extensible pallet board, which comprises a base board. Further, a through hole is disposed on the base board, a glass steel anchor rod passes through the through hole, an outer bushing is fixedly mounted on the base board, an inner bushing is disposed inside the outer bushing, a protruding step is arranged at the upper end of the inner bushing, a step hole engaged with the inner bushing is arranged at the upper end of the inner wall of the outer bushing, and a gap is arranged between the bottom end of the inner bushing and the base board. Compared with the prior art, the utility model has the advantages of good buffering shock pressure and being capable of protecting the glass steel anchor rod.
Description
One, technical field
The utility model relates to a kind of pallet, is specially a kind of extensible pallet that plays cushioning effect protection anchor pole.
Two, background technology
The supporting use of pallet and glass fibre reinforced plastics rockbolts can be used for the operation of coal mine downhole crossheading wall supporting, antistatic, fire-retardant, advantages such as intensity is high, easy cutting that glass fibre reinforced plastics rockbolts has, it has avoided problems such as the down-hole coal dust is on fire, gas explosion, but glass fibre reinforced plastics rockbolts does not extend prestressing force, when surge is come under the coal mine, large quantities of glass fibre reinforced plastics rockbolts will rupture, and mine accident can occur when serious, cause very big economic loss.
Three, summary of the invention
The utility model provides a kind of extensible pallet at above weak point, and it can well alleviate surge and cover glass steel anchor rod.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of extensible pallet comprises base plate, and base plate is provided with the through hole that glass fibre reinforced plastics rockbolts passes, be fixed with external bushing on the base plate, be provided with neck bush in the external bushing, the neck bush upper end is provided with outstanding step, and external bushing inwall upper end is provided with the stepped hole that matches with neck bush; Between neck bush bottom and the base plate space is arranged.
Above-mentioned extensible pallet, the external bushing strength of materials is greater than the neck bush strength of materials; The neck bush material is a nylon.
The external bushing and the neck bush that are provided with cooperatively interact by step; when the glass anchor pole is subjected to surge; surge acts on the neck bush on the pallet; because the neck bush material is a nylon material; hardness and intensity is less than the external bushing material hardness, and the step of neck bush is destroyed to be fallen, and anchor pole impacts neck bush to be made it to move downward; alleviate surge, well protected glass fibre reinforced plastics rockbolts.
Four, description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the local enlarged diagram of Fig. 1.
Five, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
As shown in the figure, a kind of extensible pallet comprises base plate 1, base plate 1 is provided with the through hole that glass anchor pole 4 passes, and is fixed with external bushing 2 on the base plate 1, is provided with neck bush 3 in the external bushing 2, neck bush 3 upper ends are provided with outstanding step, and external bushing 2 inwalls upper end is provided with the stepped hole that matches with neck bush 3; Between neck bush 3 bottoms and the base plate 1 space is arranged.
Base plate 1 adopts steel plate, is shaped as squarely or circular, and thickness is 6-8mm, and through-hole diameter is 18-24mm.
External bushing 2 strengths of materials are greater than neck bush 3 strengths of materials; External bushing 2 adopts steel pipe, and wall thickness 5-8mm highly is 30-60mm, and neck bush 3 adopts nylon material to make, and highly is 16-20mm, and the shoulder height on its outer wall is 1-2mm, and neck bush 3 is enclosed within on the external bushing 2.
During use, on the mine inwall, punch, anchor pole is placed keep away in the hole, then that the base plate of pallet is downward, be inserted in the anchor pole, with nut the upper end of anchor pole is fixed getting final product then.
