Abstract
The utility model discloses a novel anti -shearing stock, the slip casting anchor rope technical field of usefulness is strutted to concretely relates to mine engineering, and it has solved current ordinary stock can not bear the not enough of the great stress that shears. This novel anti -shearing stock, including the wire rope thigh, but the head of wire rope thigh even has slip casting tapering head, but the diameter of slip casting tapering head is greater than the sheathed tube diameter, the middle part cover of wire rope thigh has the sleeve, the sleeve includes a plurality of sleeve pipes that dock mutually, the sleeve pipe is rigid sleeve pipe, and just each sheathed tube diameter is the same, length diverse, the afterbody of wire rope thigh is equipped with one section screw thread, it has the nut to twist on the screw thread, be equipped with the tray between nut and the sleeve, the tray is scalable tray, the one end coupling nut of tray, other end connecting sleeve, telescopic inside is equipped with the slip casting pipeline.
Description
Technical field
The utility model relates to the grouting cable anchor technical field that mine engineering supporting is used, and is specifically related to a kind of novel anti-shearing anchor pole.
Background technology
Suspension roof support, not only for preliminary bracing, is also a part for permanent support, with improve rock mass self mechanical property, fillPoint performance rock mass self-supporting ability, the monolithic stability that ensures rock slope body and country rock and safety, can betterment works environment and construction quality,But exist in crack and the loose side slope situation of rock at country rock, depend merely on anchorage effect that anchor pole is single and sometimes also do not reach to control and encloseThe object of rock shearing resistance distortion, needs anchor pole can bear larger anti-shearing force. The common anchor body of rod cannot provide enough shearing resistance strongDegree, in the situation that shearing force is excessive, anchor pole is cut off.
Utility model content
The purpose of this utility model is the deficiency that can not bear larger shearing stress for existing common bolt, provides and has passed throughAt the middle part of strand wire, cover has sleeve, and sleeve is made up of multiple sleeve pipes that socket-connect, and each sleeve pipe is in the process of nut screwing clampingPhase mutual friction, the novel anti-shearing anchor pole of one of opposing shear stress.
The following technical scheme of the concrete employing of the utility model:
A kind of novel anti-shearing anchor pole, comprises strand wire, and the head of described strand wire is connected with can slip casting taper head, described steelThe middle part cover of silk rope strand has sleeve, described sleeve to comprise multiple sleeve pipes that connect, and the afterbody of described strand wire is provided with one section of spiral shellLine, is screwed with nut on described screw thread, between described nut and sleeve, is provided with pallet, one end attaching nut of described pallet, anotherEnd branch sleeve, the inside of described sleeve is provided with grouting pipeline.
Preferably, described diameter that can slip casting taper head is greater than the diameter of casing pipe.
Preferably, described sleeve pipe is that the diameter of rigid sleeve pipe and each sleeve pipe is identical, and length is different.
Preferably, described pallet is scalable pallet.
The beneficial effect the utlity model has is: apply prestressing force by nut, adjustable length this anchor pole can be put into boringAnd anchoring; After installing, in the time being subject to larger shear stress, connecting portion phase mutual friction between each sleeve pipe, opposing shear stress; WhenThe changing of the relative positions occurs between sleeve pipe when shear stress is larger, and while strand wire starts stressed, continues the supporting intensity that provides enough; This is newThe anti-shearing anchor pole of type both can be resisted pressure, tension by sleeve, again can be stressed by the strand wire in sleeve, and be anchor poleEnough shearing resistance, tensile strength is provided, prevents that anchor pole is damaged.
Brief description of the drawings
Fig. 1 is a kind of novel anti-shearing anchor structure schematic diagram.
Wherein, 1 is strand wire, and 2 is nut, and 3 is pallet, and 4 is sleeve pipe, and 5 is can slip casting taper head, and 6 is grouting pipeline.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description of the invention of the present utility model is described further:
As shown in Figure 1, a kind of novel anti-shearing anchor pole, comprises strand wire 1, and the head of strand wire 1 is connected with can slip casting coneDegree 5, diameter that can slip casting taper head 5 is greater than the diameter of sleeve pipe. The middle part cover of strand wire has sleeve, and sleeve comprises multipleThe sleeve pipe 4 connecting, sleeve pipe 4 is that the diameter of rigid sleeve pipe and each sleeve pipe 4 is identical, length is different. Strand wire 1Afterbody is provided with one section of screw thread, is screwed with nut 2 on screw thread, is provided with pallet 3 between nut 2 and sleeve, and pallet 3 is scalable pallet,One end attaching nut 2 of pallet 3, other end branch sleeve, the inside of sleeve is provided with grouting pipeline 6.
The operation principle of this novel anti-shearing anchor pole is: in the process of fastening nut, nut 2 is in contact with one another with pallet 3, sleeve pipe 4,Anchor rod body is applied to pulling force, and termination slip casting, by grouting pipeline 6 slip castings, applies prestressing force by nut 2, when being subject to cut more greatlyWhen stress, connecting portion phase mutual friction between each sleeve pipe 4, opposing shear stress; In the time that prestressing force is larger, between sleeve pipe 4, occur wrongMoving, strand wire 1 starts stressed, continues the supporting intensity that provides enough.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited in above-mentioned giving an example, this skillVariation, remodeling, interpolation or replacement that the technical staff in art field makes in essential scope of the present utility model, also should belong toProtection domain of the present utility model.
