Abstract
The utility model relates to a kind of compression rotation type and salvages anchor.Mainly solve cable in current test process to drop the problem of not easily salvaging in well.It is characterized in that: described main body (2) upper axial has groove, in groove, be connected with two compressions pawl (3) by radial rotating shaft; Described main body (2) middle part is connected with rotating cam (6), and cam (6) is fixed with block (7), and cam (6) top is provided with fixture block (5), the upper end of fixture block (5) is provided with the draw-in groove that can clamp compression pawl (3); Described main body (2) lower end is connected with bull stick (8), and bull stick (8) bottom is connected with bailer grab (9) and grapple (10).Salvage after the cable compression can dropped in down-hole by this salvaging anchor, improve the success rate of salvaging.
Description
Technical field
The utility model relates to oilfield, is a kind of for salvaging the compression rotation type salvaging anchor of down-hole with the tester of cable that drop specifically.
Background technology
In water injection well layering test process, utilize wireline test to be widely used now, the fault that cable and instrument drop in well also often occurs.Because the softer cunning of cable is not easy to salvage, original fishing tool for steel wire is not suitable for salvaging cable, makes fishing success ratio low, situation about cannot salvage often occurs.
Summary of the invention
To drop the deficiency of not easily salvaging in well to overcome cable in current test process, the utility model provides a kind of compression rotation type to salvage anchor, salvages, improve the success rate of salvaging after the cable compression can dropped in down-hole by this salvaging anchor.
The technical solution of the utility model is: a kind of compression rotation type salvages anchor, and comprise joint, joint bottom is connected with main body, and described body top axially has groove, is connected with two compression pawls in groove by radial rotating shaft; Be connected with rotating cam in the middle part of described main body, cam is fixed with block, and cam top is provided with fixture block, the upper end of fixture block is provided with the draw-in groove that can clamp compression pawl; Described main body lower end is connected with bull stick, and bull stick bottom is connected with bailer grab and grapple.
Be connected with spring B between two described compression pawls, described fixture block top is connected with spring A.
Described grapple is fixed on the center of bull stick bottom, and described bailer grab is along the circumferential direction uniform 3, and bailer grab is provided with magnet piece.
The utility model has following beneficial effect: owing to taking such scheme, and main body is provided with compression pawl, can compression cable or steel wire when compression pawl ejects, and cable or steel wire are more easily salvaged; And bailer grab is free to rotate, bailer grab there is magnetic block can adsorb steel wire or cable, thus be conducive to briar tooth cable or steel wire are caught, ensure that the success rate of salvaging.This salvaging anchor can be applicable to the salvaging of cable or steel wire, is especially applicable to the salvaging of cable, solves the problem that existing salvaging anchor is not suitable for salvaging cable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1, Fig. 2, a kind of compression rotation type salvages anchor, comprise joint 1, joint 1 bottom is connected with main body 2, described main body 2 upper axial has groove, and be connected with two compression pawls 3 by radial rotating shaft in groove, compression pawl 3 can rotate around the shaft, and be connected with spring B 12 between two compression pawls 3, compression pawl 3 can outwards be ejected under the effect of spring B 12.
Be connected with rotating cam 6 in the middle part of described main body 2, cam 6 be fixed with block 7, block 7 is angled with cam 6, and moving cam 6 can be with when block 7 rotates together to rotate.Cam 6 top is provided with fixture block 5, and the upper end of fixture block 5 is provided with the draw-in groove that can clamp compression pawl 3, may be stuck in the draw-in groove of fixture block 5 when compression pawl 3 is regained.Described fixture block 5 top is connected with spring A11.When cam 6 upwards rotates, by fixture block 5 jack-up, fixture block 5 Compress Spring A11, compression pawl 3 now may be stuck in the draw-in groove of fixture block 5, and when cam 6 rotates, fixture block 5 moves down under the effect of spring A11, and compression pawl 3 departs from draw-in groove, outwards ejects.
Described main body 2 lower end is connected with bull stick 8, and bull stick 8 bottom is connected with bailer grab 9 and grapple 10, and bull stick 8 rotates and bailer grab 9 and grapple 10 can be driven together to rotate.Described grapple 10 is fixed on the center of bull stick 8 bottom, and described bailer grab 9 is along the circumferential direction uniform 3, and bailer grab 9 is provided with magnet piece, cable or steel wire can be adsorbed on briar tooth.
This salvaging anchor is when original state, and block 7 direction is downward, and cam 6 is by fixture block by block 5 jack-up, and compression pawl 3 is regained and is stuck in the draw-in groove on fixture block 5 top.When carrying out fishing, under this salvaging anchor lower going-into-well, in the process transferred, block 7 contacts with tube wall, under the rubbing action of tube wall, block 7 rotates, band moving cam 6 rotates, and unclamp fixture block 5, fixture block 5 moves down under the effect of spring A11, make compression pawl 3 depart from the draw-in groove on fixture block 5 top, outwards eject under the effect of spring B 12.Continue to transfer, compression pawl 3 is descending along tube wall, can compression cable or steel wire when running into cable or steel wire, and the hook tooth of bailer grab 9 and grapple 10 can freely rotate, thus is firmly grasped firmly by cable, when upper carrying by the effect of oscillator, is pulled out by cable.
