Implement the technical solution of the utility model, there is following beneficial effect:
A kind of bolt withdrawing device that skids of the utility model, compared with prior art, it is point centered by the bolt that skids, by screw rod, be flexibly connected with the screw-type of assembly shell, and the clamping structure of combining movement formula jaw and collet head, by push-pull effort and torsional shear acting in conjunction on bolt, thereby the bolt that can quick and portably will skid takes out.In addition, assembly shell is with the stress surface of drum type brake, and assembly shell and the stress point of piece surface are around uniformly distributed, and can effectively stop because causing metaboly to occur after operation.The utility model can also be applicable to the bolt that skids of any at right angle setting, difformity size, improves and reprocesses efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing to embodiment is briefly described.
Fig. 1 is the skid structural representation of an embodiment of bolt withdrawing device of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the specific embodiment of the present utility model.
As shown in Figure 1, an embodiment of the present utility model, it comprises: assembly shell 1, handgrip 2, screw rod 3, limit assembly 4, clamp assembly 5.
Above-mentioned assembly shell 1 is the uncovered cylinder in bottom, and top is provided with the centre bore that can pass for described screw rod 3; Between above-mentioned screw rod 3 and centre bore, for being threaded, its top external part is fixedly connected with above-mentioned handgrip 2, is preferably in an embodiment welding manner, can certainly adopt other to be fixedly connected with mode, as affixed in pin joint, screw.
Above-mentioned limit assembly 4 is located at 3 times fragment position of screw rod, wherein, this limit assembly 4 comprises Limit Bearing 42 and limited block 41 for preventing that Limit Bearing 42 from moving relative to screw rod 3, this Limit Bearing 42 consists of relatively turnable outer ring and inner ring, inner ring is threaded connection mode and is fixedly connected with screw rod 3, and outer ring is flexibly connected with assembly shell 1 inner chamber by shape complementarity mode; Limited block 41 is positioned at the upside of inner ring, and is fixedly connected with screw rod 3, is preferably in an embodiment welding manner, can certainly adopt other to be fixedly connected with mode, and as pin joint, this limited block 41 is metal material.Thereby when rotating handgrip, the relative assembly shell 1 of screw rod 3 rotatablely moves, again due between screw rod 3 and assembly shell 1 for being threaded, when screw rod 3 rotatablely moves, also relative assembly shell 1 carries out vertically upward or moves down.Also it should be noted that, above-mentioned Limit Bearing also plays anti-rock effect, the stability while improving device operation.
Above-mentioned clamp assembly 5 is positioned at limit assembly 4 belows, and this clamp assembly comprises muff-joint device 51, be positioned at the movable jaw 52 in muff-joint device 51 outsides and be installed on the collet head 53 of muff-joint device 51; Muff-joint device 51 is fixedly mounted on described screw rod 3 lower ends.Wherein, above-mentioned muff-joint device 51 upper ends are also provided with contiguous block 54, and this contiguous block 54 is metal material, above-mentioned movable jaw 52 is according to needed angle and position, by welding, be fixedly connected with described contiguous block 54, can certainly adopt other to be fixedly connected with mode, as affixed in screw.Like this, can screw rod pulling force, torsional shear be delivered to movable jaw 52 effectively by contiguous block 54, can realize better push-and-pull, turn round and cut acting in conjunction.In an embodiment, this movable jaw 52 is the good metal material of elastic performance, with guarantee movable jaw 52 repeatedly exert pressure and pressure release state under, can realize and freely tighten up and unfold.
Above-mentioned assembly shell 1, handgrip 2, screw rod 3, limit assembly 4 and clamp assembly 5 are all arranged on same central axis.
Preferably, above-mentioned movable jaw 52 is provided with the jaw of receiving in 3 pawl points, and uncovered circumferentially uniform along described assembly shell 1 bottom.It should be noted that, pawl point position when above-mentioned movable jaw 52 draws in is a little less than the bottom of described collet head 53, with the bottom that guarantees that movable jaw can fishbolt head.
Preferably, above-mentioned collet head 53 is changeable type, to be applicable to the bolt that skids of various geomeries.
When bolt is taken out in operation, can drive screw rod 3 to rotate together by rotary handle 2, assembly shell 1 is pushed ahead simultaneously and by the inwall of assembly shell 1, movable jaw 52 is exerted pressure, allow movable jaw 52Xiang center tighten up and be stuck in bolt head bottom.After movable jaw 52 clamps, continue rotation screw-type rotary handle 2 and allows assembly shell 1 continue to push ahead, coordinate collet head 53 to drive bolts rotation simultaneously, the bolt that makes to skid is with push-and-pull and turn round and cut the mode combining and take out; When bolt is unclamped in operation, by reverse rotation screw-type rotary handle 2, assembly shell 1 is moved backward, make assembly shell 1 and movable jaw 52 in pressure release state, movable jaw 52 expands outwardly, and the bolt that makes to skid is separated with withdrawing device.In addition, because the utility model is the drum type brake stress surface of taking to skid centered by bolt, when carrying out push-and-pull operation, assembly shell and the around stress point of piece surface are uniformly distributed, can effectively stop because causing metaboly to occur after operation, be applicable to any vertically arranged bolt that skids, it is high that it reprocesses efficiency.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
