Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, Fig. 5, structure of the present utility model is, comprise the mandrel 2 as main body, by thread bush, fishing neck 1 is housed in the upper end of mandrel 2, between fishing neck 1 and mandrel 2, radial direction is provided with a holding screw 11, by the locking of holding screw 11 with fishing neck 1, ensure the reliable connection of fishing neck 1 and mandrel 2, prevent both from rotating in a circumferential direction;
In the middle part of mandrel 2, on outer round surface, slip cap is equipped with connector 3 and spring retainer 5, connector 3 downwards with spring retainer 5 apical grafting, the shaft shoulder apical grafting of spring retainer 5 lower surface and mandrel 2, spacing to spring retainer 5 of the shaft shoulder realization of mandrel 2; Diametric(al) along connector 3 and mandrel 2 runs through and is provided with a shear pin 10, runs through by shear pin 10 location that the two carries out original state; Be connected to urceolus 4 at the outer round surface thread bush of connector 3, meanwhile, urceolus 4 cylindrical that is downward and spring retainer 5 upper end edge convex shoulder is slidably socketed, and makes spring retainer 5 can not deviate from urceolus 4; Annular space (being called upper spring chamber) between mandrel 2 outer round surface and connector 3 internal circular surfaces) in be provided with upper spring 9, upper spring about 9 two ends respectively with connector 3 and spring retainer 5 apical grafting;
At the outer round surface slip cap of spring retainer 5 bottom, claw guard ring 6 is housed, claw guard ring 6 upper surface apical grafting has lower spring 8, lower spring 8 upwards with spring retainer 5 upper end convex shoulder apical grafting; Claw guard ring 6 lower surface and claw 7 apical grafting, claw 7 internal circular surfaces is socketed on mandrel 2, lower spring 8, claw guard ring 6 and claw 7 three are co-located in the annular space (being called lower spring chamber) that urceolus 4 and mandrel 2 and spring retainer 5 form, under lower spring 8 telescopic action, claw guard ring 6 moves vertically together with claw 7, thus makes claw 7 can realize moving with the relative axial position of mandrel 2.
With reference to Fig. 2, Fig. 3, Fig. 4, the bottom of mandrel 2 is provided with circumferential step, the upper end of claw 7 is cylindrical shell, the lower end of claw 7 is multiple concentric rectangle lengthy motion picture (embodiment is 3-10 sheet), the cross section of each rectangle lengthy motion picture is one section of same annulus, and each rectangle lengthy motion picture can be placed in this circumferential step by seat simultaneously; Cylindrical shell and rectangle lengthy motion picture can be made as one, or make respectively and connect as one; Each rectangle lengthy motion picture has certain elasticity, can adapt to contraction radially or expansion; The lower end periphery of each rectangle lengthy motion picture of claw 7 is provided with two-way taper seat or other shape transition faces, for the docking of tensioning mandrel 12 upper port edge.
Have two kinds of working conditions during the actual use of device of the present utility model: one be carry out normal under enter, lock, then reclaim steel wire rope blanking plug; Another kind is under special circumstances, only reclaims steel wire rope blanking plug and reclaims instrument itself.Two kinds of operation process specifically describe as follows:
1), normal reclaim operation be divided into locking before and lock latter two state.
Process before locking, as shown in Figure 2, when steel wire rope blanking plug recovery instrument is lowered in steel wire rope blanking plug, claw 7 contacts with the tensioning mandrel 12 of steel wire rope blanking plug upper end, steel wire rope blanking plug reclaims instrument to be continued to transfer, the lower spring 8 contacted with claw 7 compresses along mandrel direction, claw 7 is along mandrel upward sliding to mandrel 2 diameter of axle smaller part, the now conical surface of tensioning mandrel 12 and the conical surface friction of claw 7 extrude, claw 7 radial contraction distortion (as shown in Figure 3), thus make claw 7 enter tensioning mandrel 12 smoothly.
Process after locking, at said process claw 7 because radial contraction distortion buckles into tensioning mandrel 12, after the internal projection face of tensioning mandrel 12 is crossed in the outer lug face of claw 7, the extruding force that claw 7 receives upwards reduces greatly, under the recovery elastic deformation effect of lower spring 8, claw 7 moves downward, radial dilatation is to the position of mandrel 2 diameter of axle larger part simultaneously, the radial position of claw 7 is limited (as shown in Figure 4) by mandrel 2 and tensioning mandrel 12, therefore can not throw off from tensioning mandrel 12 because of the radial contraction of claw 7, the upper conical surface of claw 7 cylindrical and the lower conical surface of tensioning mandrel 12 inner circle fit tightly simultaneously, prevent from coming off, realize recovery instrument to be connected with the reliable of steel wire rope blanking plug.
2) that, only reclaims instrument self reclaims operation process, in recovery steel wire rope blanking plug process, as run into steel wire rope blanking plug by jam irretrievable situation, only reclaim steel wire rope blanking plug and reclaim instrument, its process is:
See Fig. 5, be connected with fishing neck 1 instrument (as bumper jar) act under, mandrel 2 impacts downwards cuts off shear pin 10, under the effect of upper spring 9, mandrel 2 and claw 7 produce axial relative motion, the lower end diameter of axle larger part of mandrel 2 gets out of the way the end of claw 7, then claw 7 has the space of radial contraction, until fishing neck 1 contacts spacing with connector 3 upper surface.Then carry on recovery instrument, there is radial contraction in the front end of claw 7 under the effect of tensioning mandrel 12, recovery instrument and steel wire rope blanking plug come off, completes unblock, thus steel wire rope blanking plug is reclaimed instrument reclaim smoothly.
