Abstract
The utility model relates to oil wells repairing tool in oil field, more particularly relates to a salvaging device for a sucker rod. The technic plan is that the device comprises an upper connector (1), an intermediate connection body (3), a barrel body (5), kava teeth (8), and a centralizing sheath, wherein the upper connector and the barrel body are connected by the intermediate connection body, the barrel body is equipped with a centralizing sheath of which the inner wall gradually becomes thinner from the top to bottom, a salvaging main body is connected with an elastic element arranged in the centralizing sheath, kava teeth are arranged on the bottom of the inner wall of the salvaging main body, expansion holes are provided on the side wall of the salvaging main body, and expansion slots are arranged between the expansion holes and the kava teeth. The utility model has the beneficial effects that a breakaway sucker rod can be easy centralized by the centralizing sheath of which the inner wall gradually becomes thinner form the top to bottom, with the help of the salvaging main body, the utility model can tightly catch hold of the breakaway sucker rod, thereby taking out of the sucker rod with reducing the difficulty and operation cost and improving economic benefits.
Description
One, technical field:
The utility model relates to a kind of oil field workover tool, particularly relates to a kind of sucker rod fishing device.
Two, background technology:
At present, the sucker rod in the scene, oil field disconnected phenomenon of taking off can occur after using for a long time, and the method that is used to salvage sucker rod mainly is by shutting down the way of maintenance, wasted a large amount of manpower and materials, also having influenced crude output; The 2nd, by existing sucker rod fishing tool, it is made up of top connection, cylindrical shell, fixture block and supporting positive cover, and this instrument must be understood the position of the disconnected sucker rod that takes off before fishing, has increased the difficulty of operation, has also improved operating cost.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of operation simple in structure, easy is provided, thereby reduces the sucker rod fishing device of operating cost.
Its technical scheme is: be made up of top connection (1), intermediate connector (3), cylindrical shell (5), slip insert (8) and supporting positive cover (10), be connected by intermediate connector (3) between top connection and the cylindrical shell, be provided with supporting positive cover (10) in the described cylindrical shell, the inwall of described supporting positive cover is that thick lower end, upper end is thin, be provided with flexible member in the supporting positive cover, the flexible member lower end connects salvages main body (7), the bottom inwall of described salvaging main body is provided with slip insert (8), the sidewall of salvaging main body is provided with inflation port (6), is provided with expansion slot (9) between inflation port and the slip insert.
The sidewall of described intermediate connector (3) is provided with more than one outage (2).
It is barb-like that the slip insert (8) that described salvaging main body (7) lower end is provided with becomes.
Described flexible member is return spring (4).
The beneficial effects of the utility model are: by the thin supporting positive cover in thick lower end, inwall upper end, make the disconnected sucker rod that takes off to be easy to be set upright, the sucker rod that can take off breaking firmly under the effect of salvaging main body is caught, thereby taking-up sucker rod, reduced task difficulty, reduce operating cost simultaneously, improved economic benefit.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: top connection 1, outage 2, intermediate connector 3, return spring 4, cylindrical shell 5, inflation port 6, salvaging main body 7, slip insert 8, expansion slot 9, supporting positive cover 10.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Its technical scheme is: be made up of top connection 1, intermediate connector 3, cylindrical shell 5, slip insert 8 and supporting positive cover 10, the top connection upper end connects sucker rod, be connected by intermediate connector 3 between lower end and the cylindrical shell, the sidewall of intermediate connector 3 is provided with more than one outage 2, be provided with three outages in this programme, be convenient to crude oil and from outage, discharge; Be provided with supporting positive cover 10 in the described cylindrical shell, the inwall of described supporting positive cover is that thick lower end, upper end is thin, the thickness of thinnest part is 10mm, being convenient to the disconnected sucker rod that takes off enters and plays centralizing function simultaneously, be provided with return spring 4 in the supporting positive cover, return spring 4 lower ends connect salvages main body 7, the bottom inwall of described salvaging main body is provided with a plurality of slip inserts 8,8 one-tenth of slip inserts are barb-like, can firmly it be hooked after the disconnected sucker rod that takes off enters, and the sidewall of salvaging main body is provided with inflation port 6, be provided with expansion slot 9 between inflation port and the slip insert, can be many expansion slots, during use, place the utility model downwards near the disconnected sucker rod that takes off from well head, at inwall is under the effect of the thin supporting positive cover in thick lower end, upper end, the disconnected sucker rod that takes off enters in the supporting positive cover, passes through slip insert, expansion slot enters the inner chamber of salvaging main body, simultaneously compression retracteding position spring 4, when sucker rod can not enter again, salvage main body and firmly fixedly resolve the sucker rod that takes off, carry the utility model on then, the sucker rod that takes off is salvaged successfully with breaking.
Claims (4)
1, a kind of sucker rod fishing device, by top connection (1), intermediate connector (3), cylindrical shell (5), slip insert (8) and supporting positive cover (10) are formed, be connected by intermediate connector (3) between top connection and the cylindrical shell, it is characterized in that: be provided with supporting positive cover (10) in the described cylindrical shell, the inwall of described supporting positive cover is that thick lower end, upper end is thin, be provided with flexible member in the supporting positive cover, the flexible member lower end connects salvages main body (7), the bottom inwall of described salvaging main body is provided with slip insert (8), the sidewall of salvaging main body is provided with inflation port (6), is provided with expansion slot (9) between inflation port and the slip insert.
