The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises pulling and running tool main body 1, is provided with axial prong mechanism 4 on the top of pulling and running tool main body 1, and axial prong mechanism 4 is connected with salvaging structure 7 by connecting pin 6, is provided with guide grab 11 in the bottom of pulling and running tool main body 1.
Have elongated slot I9 on the top of pulling and running tool main body 1, be provided with cam mechanism 2 among the elongated slot I9, cam mechanism 2 is fixed on the pulling and running tool main body 1 by camshaft 3 screw threads; One slotted hole 2-1 is arranged on the above-mentioned cam mechanism 2, and slotted hole one end has the conical surface, and an end is provided with screw thread; Be provided with steel ball 2-2 in slotted hole 2-1, steel ball 2-2 gives prominence to cam surface, and steel ball 2-2 has compression spring 2-3, and compression spring 2-3 is connected with cam mechanism compression spring plug 2-4; Cam mechanism compression spring plug 2-4 and slotted hole 2-1 screw thread terminal filament link and connect, and steel ball 2-2 combines with pulling and running tool main body 1 flank hole convex-concave, thereby the gathering and the release of mechanism 4 are mainlyed grasp in control.
Pulling and running tool main body 1 is at two apertures of flank spitting drill, steel ball 2-2 on aperture and the cam mechanism 2 is supporting, an aperture is a locking axial prong mechanism 4, and another aperture is that axial prong mechanism 4 opens back locking cam mechanism 2, avoids cam mechanism 2 because of the crooked locking phenomenon that causes of camshaft.Take cam mechanism 2 to cooperate like this, can prevent that pulling and running tool main body 1 axial prong mechanism 4 in transferring process from opening voluntarily, avoids pulling out the staggered floor position with pulling and running tool main body 1.Can avoid simultaneously cam mechanism 2 and axial prong mechanism 4 self-locking problems, thereby improve the test success rate.
The utility model can also install a cam mechanism 2 additional in the bottom of pulling and running tool main body 1 again on the basis of said structure.Its concrete structure is as follows:
Be provided with elongated slot II14 in the bottom of pulling and running tool main body 1, above-mentioned cam mechanism 2 can also be embedded among the elongated slot II14 of pulling and running tool main body 1 bottom, and cam mechanism 2 is fixed on the pulling and running tool main body 1 by guide grab camshaft 10 screw threads; Guide grab 11 embeds in the pulling and running tool main body 1 bottom elongated slot II14, and guide grab 11 is fixed on the pulling and running tool main body 1 by guide grab hold-down screw 15 screw threads.Support spring 12 1 ends embed in pulling and running tool main body 1 groove, and support spring 12 other ends embed in the guide grab cylinder groove. Bottom starting taper 13 and 1 screwed connection of pulling and running tool main body.Pocket 8 is screwed in main body 1 bottom.
An elongated slot II14 through hole is washed at guide grab 11 positions in pulling and running tool main body 1 bottom, and cam mechanism 2 is installed, and locks or discharges guide grab 11 with cam mechanism 2, and steel ball 2-2 locking mechanism also is installed on the cam mechanism 2.So just can avoid throw in catcher in transferring process, the collision of guide grab 11 and tube inner wall causes the angle of guide grab 11 to change, and causes instrument being hampered on the eccentric injection mandrel support, and the problem of blanking plug is not gone up in pulling, thereby improves the test success rate.
The utility model can also carry out architecture advances to axial prong mechanism 4 again on the architecture basics of above-mentioned two cam mechanisms 2.The concrete structure of its axial prong mechanism 4 is as follows:
Take this spline structure, can utilize and adjust piece 4-3 in assembling during fishing head, adjust the gap of axial prong mechanism 4 and fishing head connecting portion, make that fishing head is installed after, with axial prong mechanism 4 on a horizon.Can avoid simultaneously instrument in transferring, to collide, and the fishing head that causes upwarps, thereby the down-hole of causing is hampered, and improves the test success rate with tube inner wall.
The utility model operating principle is as follows: the pulling and running tool axial prong according to throwing, drag for program, is installed fishing head.Unclamp the adjustment piece hold-down screw 4-4 of the adjustment piece 4-3 in the axial prong mechanism 4, tool using adjustment adjustment piece 4-3 is connected the gap between the pipe nipple 7-1 with fishing head, make fishing head and axial prong mechanism 4 on a horizon, tighten the adjustment piece hold-down screw 4-4 that adjusts piece 4-3.Check the elastic force of axial prong support spring 5, draw axial prong mechanism 4 in, in the process of lock axial prong mechanism 4, because the steel ball 2-2 on the cam mechanism 2, under the effect of compression spring 2-3, steel ball 2-2 enters in the aperture of pulling and running tool main body 1 flank, pins cam mechanism 2, and the friction between cam mechanism 2 sides and the axial prong mechanism 4 locks axial prong mechanism 4 simultaneously.Utilize cam mechanism 2 to lock guide grab 11 equally.Connecting rope socket utilizes steel wire that instrument is lowered to below the target zone eccentric injection mandrel, on carry pulling and running tool and cross eccentric injection mandrel, upper and lower cam mechanism 2 is upset downwards under eccentric wheel drives, open axial prong mechanism 4 and guide grab 11, transfer pulling and running tool, under the guide effect of guide grab 11 and eccentric injection mandrel guide way, the fishing head in the axial prong mechanism 4 is pulled inclined to one side hole plug device out, finishes the adjustment of stratified water amount.
Owing to adopted above structure, avoided the pulling and running tool in the process of transferring, because of the problem that being hampered of causing of instrument self, self-locking, pulling are not gone up, improved the success rate of pulling blanking plug greatly, improved operating efficiency.
