Abstract
The utility model discloses an anchor cable and anchor rod combined support device which comprises an anchor rod, an anchor cable and a locking connecting device, wherein the locking connecting device comprises a locking sleeve and a clamp, a thread is arranged at one end of the locking sleeve, a bevel hole is formed in the other end of the locking sleeve, the clamp is of a frustum shape with a center hole, the clamp is arranged in the bevel hole, one end of the anchor cable is fastened on a clamp end of the locking connecting device, and one end of the anchor rod is threaded with the threaded end of the locking sleeve of the locking connecting device. According to the anchor cable and anchor rod combined support device disclosed by the utility model, the defect of instable anchorage section of the anchor cable in deep well surrounding rock support is avoided, the support effect of the anchor cable can be effectively ensured, and the application range of the anchor cable is enlarged.
Description
Technical field
The utility model relates to a kind of anchor cable and anchor pole combination supporting device.
Background technology
Mining of deep mine has become natural trend, seems particularly outstanding for the supporting of heavily stressed roadway with large deformation.At present, be mainly the method that adopts anchor pole and Application of Combined Support with Anchor for the supporting of deep-well tunnel, they can more effectively control the distortion of deep-well tunnel country rock.But for simple anchor pole and cable bolting, two all respectively have pluses and minuses.
For anchor pole, it is easy for installation, and anchoring quality is good, but anchoring scope and effective anchorage length are very limited, can not arrive more stable deep rock mass.
For anchor cable, although, its effective anchorage length is large, and can anchor in more stable rock mass and go, but complicated owing to installing, operation requirements is high, therefore, in actual mechanical process because Anchor Agent stirs the anchored force that the reason such as insufficient, that prestress application is inadequate and anchor hole is unstable greatly reduces anchor cable.In addition, because Mine anchorage cable is to be formed by the steel strand twist, there is no the effect of the left-handed of anchor pole or increase contact that right-handed thread produces and friction area etc., cause steel strand to be difficult to and the tight interlock of Anchor Agent, cause to a certain extent the anchorage cable anchoring effect not remarkable yet.
Summary of the invention
The technical problem that exists in order to solve the independent supporting of above-mentioned anchor pole or anchor cable, the utility model provides a kind of anchor cable and anchor pole combination supporting device, effectively must avoid the unsettled drawback of deep-well surrounding rock supporting stream line anchoring section, and can effectively guarantee the supporting effect of anchor cable, can enlarge the range of application of anchor cable simultaneously.
The technical solution of the utility model is as follows: comprise anchor pole, anchor cable and locking and connecting device, described locking and connecting device comprises lock sleeve and jig, lock sleeve one end is provided with screw thread, the other end is provided with bellmouth, described jig is the frustum shape that is provided with centre bore, jig is located in the bellmouth of lock sleeve, and an end of described anchor cable is fastened on the jig end of locking and connecting device, and an end of anchor pole and the lock sleeve end of thread of locking and connecting device are spirally connected.
The beneficial effects of the utility model are: the utility model is effective must avoid the unsettled drawback of deep-well surrounding rock supporting stream line anchoring section, and can effectively guarantee the supporting effect of anchor cable, can enlarge the range of application of anchor cable simultaneously.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of locking and connecting device of the present utility model.
Fig. 3 is the structural representation of jig of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises anchor pole 1, anchor cable 3 and locking and connecting device 2, described locking and connecting device 2 comprises lock sleeve 21 and jig 22, lock sleeve 21 1 ends are provided with screw thread 211, the other end is provided with bellmouth 212, as shown in Figure 3, described jig 22 is for being provided with the frustum shape of centre bore 221.As shown in Figure 2, jig 22 is located in the bellmouth 212 of lock sleeve 21.One end of described anchor cable 3 is fastened on the jig end of locking and connecting device 2, and the end of thread of an end of anchor pole 1 and the lock sleeve 21 of locking and connecting device 2 is spirally connected.
When accomplishing fluently darker anchor cable hole in the deep-well country rock, anchor pole 1 part is first put in the air, as the anchoring section of anchor cable 3.The length of anchor pole 1 can be determined by the length of required anchor cable 3 anchoring sections, and then locking anchor cable 3, has so just completed installation of the present utility model.It had both guaranteed the stability of anchor cable 3 anchoring terminations, had advantages of again that anchor cable 3 anchoring scopes and anchored force are large.
Adopt above technical scheme, can effectively avoid the deep-well surrounding rock supporting stream line 3 unsettled drawbacks of anchoring section, and can effectively guarantee the supporting effect of anchor cable 3, enlarged simultaneously the range of application of anchor cable 3.
