Abstract
The utility model belongs to oil field well field of tool, more particularly to a kind of hydraulic retractable fishing spear, including top connection, piston bush, piston, connector sleeve, cone, thread bush and salvage body, the lower end of the salvaging body is provided with spring detent, tooth-shape structure is provided on the outside of spring detent, the inside of spring detent is matched with the conical surface in the cone, and the center of the cone and piston is provided with through-hole, and the diameter of the through-hole in cone is the half of through-hole on piston.When salvaging junk using the utility model, size can be put into tubing string after cone and spring detent enter junk to block the through-hole with the matched bead of through-hole in cone, then it is suppressed into tubing string, body downlink under the impact of high pressure water flow is salvaged, to be stuck in junk securely.Therefore, the salvaging effect of the utility model is more preferable.
Description
Technical field
The utility model belongs to oil field well field of tool more particularly to a kind of hydraulic retractable fishing spear.
Background technique
Salvaging thatch is that a kind of common device for fishing drops underground salvages the type of thatch in the prior art in oil field operation
It is various, but salvage reliability have it is to be hoisted.In addition, being salvaged de- between thatch and junk after existing salvaging thatch is salvaged successfully
From relatively elaborate.
Summary of the invention
The utility model provides a kind of hydraulic retractable fishing spear, to solve the problems mentioned in the above background technology.
The technical problem solved by the utility model is implemented by the following technical solutions:
The utility model provides a kind of hydraulic retractable fishing spear, including top connection, piston bush, piston, connector sleeve, cone, spiral shell
Line set and salvaging body, top connection are threadedly attached in the upper end of piston bush, salvage body by thread bush and are connected to piston bush
Lower end, piston are arranged in piston bush, and the upper end of piston is inserted in the inside of top connection and is connected by pin, the connector sleeve
It is connect by screw thread with cone, flange, the upper end of connector sleeve and the flange pair is provided on the outside of the piston
It should be provided with clamping portion, be limited in the card slot on piston bush inner wall when flange is aligned with clamping portion, on the outside of clamping portion, it is convex
When edge and clamping portion misplace, the outside of clamping portion is deviate from out of card slot on piston bush inner wall, and the lower end of the salvaging body is set
It is equipped with spring detent, tooth-shape structure is provided on the outside of spring detent, the inside of spring detent is matched with the conical surface in the cone, described
Cone and the center of piston be provided with through-hole, and the diameter of the through-hole in cone is the half of through-hole on piston.
The utility model has the following beneficial effects:
1, when salvaging junk using the utility model, size can be put into tubing string after cone and spring detent enter junk
It with the matched bead of through-hole in cone to block the through-hole, is then suppressed into tubing string, salvages body in high pressure water flow
Lower downlink is impacted, to be stuck in junk securely.Therefore, the salvaging effect of the utility model is more preferable.
2, the utility model is designed using reversible, by suppressing after the pitching into oil pipe column, can push piston motion,
Then make cone downlink, so that the utility model and junk be made to be detached from.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- top connection, 2- piston bush, 3- piston, the clamping portion 4-, 5- flange, 6- connector sleeve, 7- thread bush, 8- are beaten
Fish out body, 9- cone, 10- spring detent, 11- pin.
Specific embodiment
The utility model is described further below in conjunction with attached drawing:
The present embodiment includes top connection 1, piston bush 2, piston 3, connector sleeve 6, cone 9, thread bush 7 and salvages body 8, is above connect
First 1 is threadedly attached in the upper end of piston bush 2, salvages the lower end that body 8 is connected to piston bush 2 by thread bush 7, and piston 3 is set
It sets in piston bush 2, the upper end of piston 3 is inserted in the inside of top connection 1 and is connected by pin 11, and the connector sleeve 6 passes through
Screw thread is connect with cone 9, and flange 5 is provided on the outside of 3 lower end of piston, and the upper end of connector sleeve 6 and the flange 5 are right
It should be provided with clamping portion 4, when flange 5 is aligned with clamping portion 4 (as shown in Figure 1), the outside of clamping portion 4 is limited in piston bush 2
In card slot on inner wall, when flange 5 and clamping portion 4 misplace, the outside of clamping portion 4 is deviate from out of card slot on 2 inner wall of piston bush.
The utility model is designed using reversible, by suppressing after the pitching into oil pipe column, piston 3 can be pushed to move, then make to bore
9 downlink of body, so that the utility model and junk be made to be detached from.
The lower end of the salvaging body 8 is provided with spring detent 10 (being equivalent to the slips on tradition salvaging thatch), spring detent 10
Outside be provided with tooth-shape structure, the inside of spring detent 10 is matched with the conical surface in the cone 9.
The center of the cone 9 and piston 3 is provided with through-hole, and the diameter of the through-hole in cone 9 is to lead on piston 3
The half in hole.When salvaging junk using the utility model, it can be put into after cone 9 and spring detent 10 enter junk into tubing string big
Then the small matched bead of through-hole in cone 9 is suppressed to block the through-hole into tubing string, salvage body 8 in high pressure water
Downlink under the impact of stream, to be stuck in junk securely.Therefore, the salvaging effect of the utility model is more preferable.
