The invention relates to the field of anchor bolt support, in particular to a bendable connector capable of smoothly installing an anchor bolt mixing resin anchoring agent.The bendable connector comprises a bit shank, a bit shank sleeve capable of bending anchor bolt connectors, a drill rod, a sleeve and an anchor bolt nut.A universal joint is connected to the bit shank, the other end of the universal joint is connected with the drill rod, the anchor bolt nut is arranged at the upper end of the drill rod, and the bit shank is inserted into the bit shank sleeve.According to the bendable connector, the problem that an anchor bolt hole and a drilling tool are not on the same axis is solved, and therefore the anchor bolt mixing resin anchoring agent can be smoothly installed.
Description
Technical field
The present invention relates to and relate to bolt supporting field, particularly relate to a kind of anchor rod stirring resin anchoring agent can be installed smoothly can curved connector.
Background technology
In bolt supporting in process, the drilling tool beating anchor pole hole and the drilling tool installing anchor rod stirring resin anchoring agent be not when being same drilling tool, the drilling tool installing anchor rod stirring resin anchoring agent be difficult to armature boring on an axis; The drilling tool beating anchor pole hole easily produces displacement in propelling process, and the leg root of drilling tool is embedded in slag, it is very difficult to mobile, causes anchor pole hole and drilling tool not on an axis. When installing anchor rod stirring resin anchoring agent, need to advance while stirring, anchor pole hole and drilling tool be not on same bar axis, and anchor pole and drill hole wall produce very big friction, the resistance increase stirred and advance, boring is middle or resin anchoring agent stirring is uneven to cause anchor pole to be stuck in, just reaching drill thrust and stir the limit of moment of torsion, anchor pole is stuck in the middle of boring, and exposing overlength cannot use, need complement anchor pole again, wasting manpower and material resources; Resin anchoring agent stirs uneven, and the anchor force of anchor pole does not reach design requirements, and supporting was lost efficacy easy roof fall, and anchor pole hole and drilling tool be not on same bar axis, it is easy to damage drilling tool and junctor. Now urgently need one: adaptation anchor pole hole and drilling tool can not install the junctor of anchor rod stirring resin anchoring agent smoothly on same bar axis.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency of the prior art provide a kind of by solve anchor pole hole and drilling tool not the problem on same bar axis make installation anchor rod stirring resin anchoring agent smoothly can curved connector.
The technical scheme of the present invention be achieved in that one can curved connector, comprise pricker tail, the bit shank sleeve of bending anchor rod connector, drill steel, sleeve and anchor pole nut; Connecting a universal joint on described pricker tail, the other end of described universal joint connects drill steel, and the upper end of described drill steel arranges anchor pole nut.
The other end of described bit shank sleeve is inserted with tubular key or ordinary connector.
The positively effect that the technical scheme of the present invention produces is as follows: use can curved connector can adjust drilling tool and armature boring on the same axis installation anchor rod stirring resin anchoring agent time angle, ensure that anchor pole and armature boring are at same bar axis, anchor rod stirring resin anchoring agent can be installed smoothly, there will not be because not coaxial anchor pole and armature boring wall produce friction resistance, the resistance stirred and advance increases, damage drilling tool or anchor pole are stuck in the middle of armature boring wall, and causing anchor pole to expose overlength cannot use.
Use can curved connector ensure install anchor rod stirring resin anchoring agent qualification rate, it is to increase anchoring quality, promote working efficiency, accelerating construction progress, alleviates the labour intensity of workman, reduce drilling tool abrasion loss.

Embodiment
One can bend anchor rod connector, as shown in Fig. 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17, comprises pricker tail 2, bit shank sleeve 3, drill steel 4, sleeve 5 and anchor pole nut 6; Connecting a universal joint 1 on described pricker tail, the other end of described universal joint connects drill steel, and the upper end of described drill steel arranges anchor pole nut, and described pricker tail is inserted in described bit shank sleeve.
The other end of described bit shank sleeve is inserted with tubular key or ordinary connector 13. The effect of described tubular key is fastening anchor nut use, and the effect of ordinary connector connects anchor pole 8 to use with jumbolter 9.
Bit shank sleeve 3 in Fig. 1 and 2 to be used for slotting ordinary connector, different anchor poles needs different junctors, curved connector 14 can join multiple ordinary connector for such one, only need when different anchor pole is installed to change ordinary connector, if only using a kind of anchor pole in construction process, the junctor of signal in Fig. 3 can be used, it is not necessary to insert ordinary connector. Jumbolter overlaps 15 with Drilling Rod End of Jumbolter, it is possible to slotting drill steel is used for beating armature boring, it is also possible to insert ordinary connector and can curved connector. Fig. 1 and Fig. 2 is the different states of same junctor, can be used for slotting ordinary connector or tubular key; Fig. 3 is directly used for installing anchor pole, agitating resin anchoring agent.
When drilling tool and armature boring not on the same axis time, drilling tool and the angle in anchor pole hole 7 can be adjusted by universal joint, there will not be because not coaxial anchor pole and armature boring wall produce friction resistance, the resistance stirred and advance increases, damage drilling tool or anchor pole are stuck in the middle of armature boring wall, and causing anchor pole to expose overlength cannot use.
The thick-layer 11 of bonding anchor pole and anchor pole hole wall with resin anchoring agent of the thin layer 10 of the bonding anchor pole of resin anchoring agent with anchor pole hole wall is caused when using ordinary connector armature boring not coaxial with jumbolter. The thin layer that the bonding anchor pole of resin anchoring agent and anchor pole hole wall occur even anchor pole and anchor pole hole wall there is no resin anchoring agent, cause anchor force to decline; Occurring that the thick-layer of the bonding anchor pole of resin anchoring agent and anchor pole hole wall causes anchoring agent to stir uneven, anchor force declines.
Use the present invention curved connector can prevent resin anchoring agent thin layer and thick-layer in Fig. 9. The present invention can curved connector when can ensure not coaxial with jumbolter in anchor pole hole, anchor pole can be anchored in the middle of anchor pole hole, such as Figure 10. anchor rod anchored in the middle of armature boring, namely can ensure that resin anchoring agent stirs evenly, the effective anchoring of the resin anchoring agent of anchor pole and anchor pole hole wall can be ensured again, the homogeneous layer 12 of the bonding anchor pole of resin anchoring agent and anchor pole hole wall so just occurred, the adhesive effect of resin anchoring agent is best, is easy to reach design anchor force.
