Abstract
A yielding anchor cable comprises an anchor cable steel strand, a pallet and lockset. The pallet and the lockset are arranged at the tail end of the anchor cable steel strand, a yielding device is arranged between the pallet and the lockset; and metal washers are arranged at both ends of the yielding device. During the process of maintaining the stability of laneway wall rock, the anchor cable can not only provide a high working resistance, but also can offer an appropriate yielding deformation for the large deformation of the wall rock. Therefore, the wall rock deformation can be controlled efficiently, the probability of early tensile failure and destruction of the anchor cable is avoided, an anchor cable supporting system is well protected, high land pressure expansion and deformation of the laneway wall rock at the deep part can be controlled effectively, the purpose of reinforced support for the laneway wall rock at the deep part is achieved, the structure is simple, the support strength is high, and the using effect is good.
Description
Technical field
The utility model relates to a kind of pressure anchor cable that allows, and is particularly useful for the supporting of underworkings country rock.
Background technology
Coal enters deep mining, geostatic stress increases, and the roadway surrounding rock highland presses the characteristics of large deformation very outstanding, and rock deformation often surpasses the elongation of anchor shaft anchor cable and causes broken section of anchor cable, then cause back or collapsing of portion of group to emit, cause the passive and personnel's of production safety injures and deaths.The common anchor cable that uses can only provide the high workload resistance at present, and it is disrumpent feelings to be stretched under certain pressure, therefore, wishes anchor cable when high-drag is provided, can have certain elongation per unit length not broken to protect it.But the elongation per unit length of steel strand remains unchanged substantially, need be at pressure device that allows that can produce certain elongation when the rock mass bulbs of pressure surpass anchor cable intensity of auxiliary installation on the anchor cable.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provide a kind of on the original structure basis, set up one allow pressure device allow the pressure anchor cable, realize anchor cable when high-drag is provided with this, can have certain elongation per unit length not broken to protect it.
The pressure anchor cable that allows of the present utility model comprises the anchor cable steel strand, and pallet and lockset are located at the afterbody of anchor cable steel strand with pallet and lockset, is provided with between pallet and the lockset to allow pressure device, allows the pressure device two ends be equipped with metal washer; Described allow press-fit be changed to a cydariform collar.
The beneficial effects of the utility model: add one at the afterbody of high strength anchor cable and allow pressure device; make anchor cable in safeguarding the stable process of roadway surrounding rock; give full play to the performance of anchor cable high-drag supporting; not only can provide the high workload resistance; large deformation characteristics that can also suitable for surrounding rock; produce and necessarily to allow the pressure distance, effectively protect the intact of anchor cable assembly.Can award the suitable compressive strain that allows with the large deformation of country rock; effectively control surrouding rock deformation; also avoid anchor cable to be broken the probability of destruction too early, can well protect the cable bolting system, to the strong control of the high geostatic pressure dilatation distortion of deep tunnel country rock; realize the reinforcement supporting of deep tunnel country rock; it is simple in structure, the supporting intensity height, and ability is big; result of use is good, has practicality widely.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-anchor cable steel strand, 2-pallet, 3-metal washer, 4-allow pressure device, the 5-lockset.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
The pressure anchor cable that allows of the present utility model, mainly by anchor cable steel strand 1, pallet 2, metal washer 3, allow pressure device 4 and lockset 5 constitute, with pallet 2, metal washer 3, allow pressure device 4 and lockset 5 orders be set on the afterbody of anchor cable steel strand 1, implement fastening to country rock.Allow the pressure device 4 be a cydariform collar, two ends are respectively equipped with metal washer 3, are located between pallet 2 and the lockset 5.
During use: after the boring anchoring agent is pushed in the boring, presses anchor cable that the anchoring agent is slowly pushed boring with allowing, until push away motionless till; The anchor cable agitator and the anchor cable afterbody that are installed in advance on the rig are connect, stir the anchoring agent fast, anchor cable stirs the back that finishes lockset 5 tension anchor cables, and anchor cable is when providing the high workload resistance, by allowing pressure device 4 produce necessarily to allow the pressure distance, large deformation that can suitable for surrounding rock.
Claims (2)
1. one kind allows the pressure anchor cable, comprise anchor cable steel strand (1), pallet (2) and lockset (5), it is characterized in that: the afterbody that pallet (2) and lockset (5) is located at anchor cable steel strand (1), be provided with between pallet (2) and the lockset (5) and allow pressure device (4), allow pressure device (4) two ends be equipped with metal washer (3).
