Abstract
The utility model discloses a break-preventive device for an anchor. An anchor body (1) sequentially crosses through a roof plate steel strip (2), a pallet (5), a yielding tube (3) and a friction washer (4) from top to bottom, with (2), (5), (3) and (4) appressed with each other; a nut (6) nested at the lower end of the anchor body (1) is connected with the anchor body (1) through screw thread; a cylindrical lug is arranged at the central position of the yielding tube (3) whose two ends are shaped as a circular tube. The utility model has the advantages of low production cost, simple installation and using, as well as obvious protecting effect.
Description
Technical field
The utility model relates to a kind of device that prevents the tunnel supporting anchor rod fracture.
Background technology
Present mine timbering anchor poles made from steel that adopt, when the roof pressure of anchor pole institute supporting was excessive, anchor pole was because hold and dare not accept pressure and cause fracture, thereby caused danger in the tunnel, formed potential safety hazard easily, caused unnecessary loss more.
Summary of the invention
For solving the problem that anchor pole is stressed and ruptures easily, the utility model provides a kind of anchor pole anti-fracture device, and its technical scheme of taking is:
The anchor rod body of this device passes top board steel band, the pallet be close to mutually from the top down successively, allow pressure pipe and friction pad, and the nut thread that is enclosed within the anchor rod body lower end connects anchor rod body, and two ends are that the pressure pipe centre position that allows of tubular is the circle drum projection.
Allow the circle drum projection of pressure pipe can be 1-2, the both sides of top board steel band are recessed to be elongate recesses.
Being with the centre position on the anchor rod body is the pressure pipe that allows of circle drum projection; owing to allow the stressed yield strength of pressure pipe be lower than the yield strength of anchor pole slightly; therefore when being subjected to pressing impact consumingly; allow pressure pipe elder generation stress deformation compensator or trimmer pressure; thereby anchor pole is protected; avoid fracture, what can guarantee to construct normally carries out.
Therefore to have a cost of production low for this device, install and use simple, the tangible characteristics of protection effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is for allowing the vertical view of pressure pipe in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As depicted in figs. 1 and 2, anchor rod body 1 passes top board steel band 2, the pallet 5 be close to mutually from the top down successively, allow pressure pipe 3 and friction pad 4, pallet 5 and allow pressure pipe 3 make by steel, the recessed formation elongate recesses in the both sides of top board steel band 2, allow pressure pipe 3 two ends be tubular, position is the circle drum projection in the middle of it, and this circle drum projection is 1 or 2, and the recessed formation of the mid portion of pallet 5 is discoid.Nut 6 is enclosed within the lower end of anchor rod body 1 and is threaded with it.
During use, insert the top of anchor rod body 1 in coal seam or the rock stratum also fixing earlier, be inserted in top board steel band 2, pallet 5 then from the lower end successively, allow pressure pipe 3 and friction pad 4, subsequently nut 6 is spun on anchor rod body 1 lower end, by adjust the position of nut 6 on anchor rod body 1 top board steel band 2, pallet 5, allow pressure pipe 3 and friction pad 4 tighten together, top board steel band 2 is close to top board at this moment, and other auxiliary rack can be fixed in anchor rod body 1 bottom.
Claims (3)
1. anti-fracture device of anchor pole, comprise anchor rod body (1), it is characterized in that, anchor rod body (1) passes top board steel band (2), the pallet (5) be close to mutually from the top down successively, allow pressure pipe (3) and friction pad (4), the nut (6) that is enclosed within anchor rod body (1) the lower end anchor rod body (1) that is threaded, two ends are that pressure pipe (3) centre position that allows of tubular is the circle drum projection.
2. the anti-fracture device of anchor pole according to claim 1 is characterized in that, allows the circle drum projection of pressure pipe (3) be 1-2.
3. the anti-fracture device of anchor pole according to claim 1 and 2 is characterized in that, the both sides of top board steel band (2) are recessed to be elongate recesses.
