Description
Technical field
The utility model relates to down-hole, a kind of oil field fishing tool.
Background technology
In fishing, sometimes to the outside dimension of down-hole tubulose fish understand very inaccurate, and only know a probable ranges, so just require the salvaging scope of fishing tool to want greatly, so that can once salvage success.Common lifting type releasing socket though can realize grabbing the requirement of dragging for and withdrawing from fish where necessary, is salvaged the area requirement strictness, and a kind of slips can only be salvaged the fish of a size.And common slip socket encloses greatly though salvage, and can not satisfy the requirement of withdrawing from fish where necessary.
The utility model content
The purpose of this utility model provide a kind of salvage scope big, can realize grabbing the lifting type that drags for and withdraw from where necessary fish and can move back fishing socket on a large scale.
Technical solution of the present utility model is: it comprises top connection, cylindrical shell, slips and guide shoe, guide shoe links to each other with the cylindrical shell lower end, slips is tubular and is positioned at cylindrical shell guide shoe top, the top connection bottom is placed in the cylindrical shell, the top connection middle part links to each other with the cylindrical shell upper end, be respectively equipped with inner conical surface and the male cone (strobilus masculinus) that is meshed on the inwall of cylindrical shell bottom He on the slips periphery, be provided with the slips frame between top connection and the slips in the cylindrical shell, slips frame upper end is placed in the top connection, lower end and slips clamping mutually, the external cylindrical surface of top connection bottom is provided with slideway, and it is fixed thereon that the slips frame is provided with an end, the other end is positioned at the commutation pin of slideway.
Technique effect of the present utility model is: it is big that it not only salvages scope, and can realize grabbing and drag for and withdraw from where necessary fish, by under carry on hitting directly and can withdraw from fish, there are splitting, hettocyrtosis and not too regular fish to salvage effectively for the fish head, are a kind of function admirable, simple in structure, processing ease, grab and drag for and withdraw from the reliable novel fishing tool of fish.

The specific embodiment
As shown in the figure, the lifting type of present embodiment can move back on a large scale, and fishing socket comprises top connection 1, cylindrical shell 2, slips 3 and guide shoe 4, guide shoe 1 links to each other with cylindrical shell 2 lower ends, slips 3 is tubular and is positioned at cylindrical shell 2 guide shoes 4 tops, top connection 1 bottom is placed in the cylindrical shell 2, top connection 1 middle part links to each other with cylindrical shell 2 upper ends, be respectively equipped with inner conical surface 21 and the male cone (strobilus masculinus) 31 that is meshed on the inwall of cylindrical shell 2 bottoms He on slips 3 peripheries, be provided with slips frame 5 between top connection 1 and the slips 3 in the cylindrical shell 2, slips frame 5 upper ends are placed in the top connection 1, lower end and slips 3 clamping mutually, the external cylindrical surface of top connection 1 bottom is provided with slideway 11, and it is fixed thereon that slips frame 5 is provided with an end, the other end is positioned at the commutation pin 6 of slideway 11.
The top of top connection 1 is provided with internal thread 12, and the middle part is provided with external screw thread 13.The top and bottom of cylindrical shell 2 are respectively equipped with internal thread 22 and following internal thread 23.Slideway 11 is made up of long slideway 14, short slideway 15 and inclined ramp 16, and long slideway 14 is axial alternate setting with short slideway 15, and inclined ramp 16 is connected between long slideway 14 and the short slideway 15.The inner headed face of slips 3 is processed with salvages screw thread 32.Slips frame 5 is provided with commutation pin-and-hole 51 for the upper end barrel, and the lower end is provided with the cylindrical body of slips dop 52.
Operating principle: after the fish head of fish entered cylindrical shell 2, it was up at first to promote slips 3, and separately slips 3 enters in the middle of two slips.It is up to promote slips frame 5 then, and it is up with commutation pin 6 to drive slips 3 simultaneously.Commutation pin 6 when up, by the effect of inclined ramp 16, commutates in the long slideway 14 in slideway 11.Carry fishing socket on this moment, slips frame 5 and slips 3 are relative descending under the effect of deadweight, because commutation pin 6 is in long slideway 14, so the descending distance of slips frame 5 is big, and the descending distance of slips 3 is also big.Because the interaction of the male cone (strobilus masculinus) 31 of slips 3 and the inner conical surface 21 of cylindrical shell 2 make slips 3 embrace fish tightly, and upper lifting force is big more, the power of holding tightly is also big more, does already thereby realize salvaging.If fish is blocked, be difficult to pick up, can below hit drilling tool, the male cone (strobilus masculinus) 31 of slips 3 and the inner conical surface 21 of cylindrical shell 2 are thrown off, and it is up to promote slips frame 5.Because the effect of slide ramp, commutation pin 6 slips into short slideway 15.Carry drilling tool on this moment, and it is up to drive fishing socket.Because commutation pin 6 is in short slideway 15, slips frame 5 can not drop at the end, and holds slips 3 and can not drop at the end, and the male cone (strobilus masculinus) 31 of slips 3 can not mesh with the inner conical surface 21 of cylindrical shell 2, so slips do not have clamping force 3 this moments, and fishing socket can withdraw from fish.
