Abstract
The utility model discloses a shock resistant anchor rod tray. The shock resistant anchor rod tray comprises a tray body and also comprises a columnar cap and a pressure relief ring; a tray body through hole is formed in the middle of the tray body; a columnar cap through hole is formed in the middle of the columnar cap; the pressure relief ring sleeves the tray body; the columnar cap is positioned above the pressure relief ring and buckled on the upper end of the tray body; three pressure relief slots are uniformly distributed on the pressure relief ring; the diameter of the columnar cap through hole is equal to the diameter of the tray body through hole. With the adoption of the shock resistant anchor rod tray, the shock of dynamic load is effectively buffered, the yielding capacity is enforced, the shock resistant anchor rod tray can realize the effect of secondary buffering and pressure bearing when resisting rock burst disaster, the anchor rod tray cannot be penetrated or cracked easily, the structure is simple, the processing technique is convenient, the shock resistant stability is good, and the adaptability is strong.
Description
Technical field
The utility model relates to a kind of pallet, especially a kind of shock resistance anchor rod pallet board.Belong to field of mechanical technique.
Background technology
Bolt support has a wide range of applications in underground chamber, roadway support, and along with the continuous increase of the mining degree of depth, rock blast hazard takes place frequently, and it is serious that tunnel and stope are subject to the impact of dynamic loading.Anchor rod pallet board body is as the important component part of support system, at present widely used plate pallet, butterfly pallet, the M shape pallet etc. of mainly containing; In Bolt System, existing pallet by pressure energy power a little less than, opposing when rock blast hazard effect undesirable, the situation that normal appearance is penetrated and pressure break is destroyed, have a strong impact on the stability of support system, jeopardizing the resistance to overturning of underground chamber, having serious potential safety hazard.
Utility model content
In order to solve the existing weak point of above-mentioned technology, the utility model provides a kind of shock resistance anchor rod pallet board.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of shock resistance anchor rod pallet board, comprise tray body, and it also comprises column cap, unloads pressure ring; The centre of tray body has a tray body through hole; The centre of column cap has column cap through hole; Release ring set is put on tray body;
Column cap is positioned at and unloads the top of pressure ring and buckle the upper end at tray body.
Unload and on pressure ring, be evenly equipped with three pressure relief grooves.
The equal diameters of column cap through hole and tray body through hole.
The utility model can cushion the impact while being subject to dynamic loading effectively, allows pressure energy power strengthen, and can play the effect of secondary buffer pressure-bearing in the time of opposing rock blast hazard, be difficult for being penetrated and pressure break, simple in structure, processing technology is convenient, stability of shock resistance is good, strong adaptability.

In figure: 1, tray body; 2, column cap; 3, unload pressure ring; 4, pressure relief groove; 5, column cap through hole; 6, tray body through hole; 7, nut; 8, anchor pole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-Figure 4, the utility model comprises tray body 1, column cap 2, unloads pressure ring 3; The centre of tray body 1 has a tray body through hole 6; The centre of column cap 2 has column cap through hole 5; Unloading pressure ring 3 is nested with on tray body 1; Column cap 2 is positioned at and unloads the top of pressure ring 3 and buckle the upper end at tray body 1.
Unload and on pressure ring 3, be evenly equipped with three pressure relief grooves 4.The equal diameters of column cap through hole 5 and tray body through hole 6.
Anchor pole 8 runs through column cap through hole 5 and tray body through hole 6; When use, the pad of placing above of column cap 2 is also nested with in the upper end of anchor pole 8 with nut 7 and tightens (reaching supporting prestressing force).
A stable support system of the common formation of all parts of the present utility model, in the time that anchor pole 8 is subject to dynamic load impact, unloading pressure ring 3 ruptures at pressure relief groove 4 places, column cap 2 moves to tray body 1 direction, column cap through hole 5 in column cap is after the tray body through hole 6 touching on tray body 1, realize secondary contact, continue carrying; Nut 7, column cap 2, tray body 1 and anchor pole 8 form support system again, have guaranteed the stable of support system, can effectively resist the impact of dynamic loading.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make within the scope of the technical solution of the utility model, also all belong to protection domain of the present utility model.
