Background technology
Bolt support technology is generally adopting aspect the reinforcing of underground construction and mine timbering and side slope, tunnel, dam body.The bolt support owner moves supporting, takes full advantage of roadway surrounding rock self-supporting ability, and the rock stratum is strapped in together, makes country rock form reinforce arch or compound beam or suspension function and realizes that reinforcing to rock is with supported laneway.
Usually, when reality is used, require without many anchor points of resin anchor pole external diameter and bore diameter Best Coupling, namely anchor pole can insert smoothly boring again can be at first nutting, and integral-rotation does not occur in anchor pole.But in practice, the mode of drilling that generally adopts according to present mine, when beating tunnel side hole because of rig air leg (or hydraulic pressure leg) top power and drilling rod not on the same straight line, cause side hole in tunnel to beat not straight, and Kong Yueshen is more not straight, just can insert smoothly without many anchor points of resin anchor pole after needing suitably to repair directly to boring, the rear boring of correction straightens but the aperture change is large, and the anchor pole external diameter is less than bore diameter.Can not satisfy the Best Coupling of anchor pole and boring, when causing nutting or the body of rod, anchor pole will integral-rotation, can't tighten, affect the anchoring effect of anchor pole, therefore, insert the rear can check anchor pole integral-rotation of boring without many anchor points of resin anchor pole and just become the key of using success or failure for this kind anchor pole.
The utility model content
In order to solve anchor pole of the prior art integral-rotation when inserting the rear first nutting of boring, affect the technical problem of anchoring effect, the utility model provides a kind of can rotate many anchor points anchor pole by the integrally rotated check of first fastening check anchor pole.
The technical solution adopted in the utility model is: what check rotated is processed with screw thread without many anchor points of resin anchor pole at an end of the body of rod, the other end is processed as down wedge shape, the screwed end of the body of rod passes the installing hole of supporting plate, by with the adaptive nut of screw thread that supporting plate and the body of rod is fastening, be disposed with the support unit pipe of swollen banded penstock and at least one joint at the body of rod, the support unit pipe is arranged on the lower end of swollen banded penstock, is provided with the check key that can prevent that the body of rod from reversing at the outer wall of upper swollen banded penstock.
Above-mentioned check key is arranged on the check spline that spirality upside-down mounting burr on the swollen banded penstock outer wall or outer are knife-edge.
It is good that above-mentioned check spline is 3～5, is evenly distributed on vertically the periphery of swollen banded penstock.
Above-mentioned support unit pipe is 3～5 joints that head and the tail link, every joint support unit pipe comprises that the support that connects successively holds a writing brush or pen-write and lower swollen banded penstock, the two ends external diameter that described support holds a writing brush or pen-write is respectively less than the port internal diameter of upper swollen banded penstock and lower swollen banded penstock, the interlude external diameter is greater than the internal diameter of upper swollen banded penstock and lower swollen banded penstock, and the two ends external diameter that holds a writing brush or pen-write of support is less than the external diameter of its interlude, and upper swollen banded penstock and support hold a writing brush or pen-write the two end axles of an adjacent end and lower swollen banded penstock to all being processed with open slot.
The utility model arranges the check key of spiral burr or knife-edge check spline formation by the upper swollen banded penstock at anchor pole, the axial rub resistance of check key and drill hole wall when not affecting the anchor pole insertion, simultaneously, effective check anchor pole integral-rotation, reach reliably initial anchoring effect, processing is simple, and is easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model the first embodiment.
Fig. 2 is the structural representation of the utility model the second embodiment.
The specific embodiment
Now by reference to the accompanying drawings to further specifying without many anchor points of resin anchor pole that check of the present utility model rotates:
Embodiment 1
Referring to Fig. 1, check of the present utility model rotation without many anchor points of resin anchor pole by the body of rod 1, nut 2, supporting plate 3, check key 4, upper swollen banded penstock 5, support hold a writing brush or pen-write 6, lower swollen banded penstock 7 connects and consists of.
End at the body of rod 1 is processed with screw thread, the other end is processed into down wedge shape, offers installing hole at the middle part of supporting plate 3, and the body of rod 1 a screwed end passes installing hole, supporting plate 3 is set on the body of rod 1, by with the adaptive hex nut 2 of screw thread that supporting plate 3 is fixing with the body of rod 1.Be disposed with swollen banded penstock 5 and held a writing brush or pen-write by support at the opposite side body of rod 1 outer wall of supporting plate 3 and 6 be connected in series the support unit pipe that consists of with lower swollen banded penstock 7, outer wall at upper swollen banded penstock 5 is provided with the check key 4 that prevents that the body of rod 1 from reversing, it is spirality upside-down mounting burr, so neither affect anchor pole and stretch into boring, prevent the anchor pole integral-rotation in the time of can working as initial fastening nut 2 again, affect anchoring effect.
Support holds a writing brush or pen-write and is processed with the crack on 6 the tube wall, and its external diameter is to reduce gradually from the centre to two, be that the external diameter at its two ends is less than the external diameter of interlude, its wall thickness is to be successively decreased to thin by thick from the centre to both sides, and the external diameter at its two ends is less than the port internal diameter of upper swollen banded penstock 5 and lower swollen banded penstock 7, the external diameter of interlude is greater than the internal diameter of upper swollen banded penstock 5 and lower swollen banded penstock 7,6 two ends can extend in the port of swollen banded penstock 5 and lower swollen banded penstock 7 so that support holds a writing brush or pen-write, with upper swollen banded penstock 5, support hold a writing brush or pen-write 6 and lower swollen banded penstock 7 be connected.Upper swollen banded penstock 5 and support hold a writing brush or pen-write 6 adjacent ends and lower swollen banded penstock 7 two ends axially be provided with open slot, when the expansion stay pipe is subject to expanding extruding force, open slot can outwards strut, ground is produced suspension function, simultaneously support 6 bodies of rod 1 of holding with a firm grip that hold a writing brush or pen-write have increased the strong point of whole anchor pole.
During use, screw nut, when the expansion stay pipe was subject to expanding extruding force, open slot can outwards strut, and ground is produced suspension function, and spirality upside-down mounting burr inserts in the ground, prevents the anchor pole integral-rotation, so that anchor is tight.
