Complicated and the low problem of organic efficiency the blanking plug of structure reclaim fishing tool.
The technical solution of the utility model is:
A kind of blanking plug reclaims fishing tool, it by mandrel, fishing head, drag for pawl, spring pressure cap, urceolus, spring of giving up, bullet
Spring abutment, salvage spring and salvage spring base and constitute, it is characterised in that: the threaded one end of mandrel is provided with fishing head, mandrel another
One end is movably set with drags for pawl, drags for and is provided with spring pressure cap by urceolus screw thread between pawl and fishing head, spring pressure cap with drag for pawl
Between by spring base equipped with spring of giving up, between spring base and urceolus by salvage spring base equipped with salvage spring.
The described pawl that drags for is split blade type structure, drags for and is provided with positive stop lug boss on pawl, and positive stop lug boss is conflicted with urceolus and is connected.
One end of described mandrel is provided with defining flange, and the cross section of described defining flange is taper.
Described fishing head is connected by holding screw is fixing with mandrel, and spring pressure cap is by shear pin with mandrel even
Connect.
Described salvaging spring base is connected with dragging for pawl conflict.
The utility model has the advantage of:
This blanking plug reclaims fishing tool compact conformation, easy to use, by bumper jar this salvaging of downward jarring during work
Instrument, can pin blanking plug, can be salvaged by blanking plug by bumper jar this fishing tool of upwards jarring subsequently and reclaim.This
This fishing tool outer can also realize promptly giving up when meeting emergency.Solve the structure complexity that existing fishing tool has
The problem low with organic efficiency, meets the needs of enterprise's production and application.

Detailed description of the invention
This blanking plug reclaim fishing tool by mandrel 1, fishing head 2, drag for pawl 3, spring pressure cap 4, urceolus 5, spring 6 of giving up,
Spring base 7, salvaging spring 8 and salvaging spring base 9 are constituted；The threaded one end of mandrel 1 is provided with fishing head 2, fishing head 2 and mandrel
1 connects by holding screw 12 is fixing.
The other end of mandrel 1 is movably set with and drags for pawl 3, and dragging for pawl 3 is split blade type structure, drags for and is provided with positive stop lug boss on pawl 3
10, positive stop lug boss 10 is conflicted with urceolus 5 and is connected.The purpose arranging positive stop lug boss 10 is: fitting through of positive stop lug boss 10
Urceolus 5 carries out spacing to dragging for pawl 3, prevents dragging for pawl 3 and disengages with urceolus 5.
It is conical limit flange 11 that one end of mandrel 1 is provided with cross section.The cross section of defining flange 11 is arranged to taper
Purpose is: when making this fishing tool carry out operation, drags for pawl 3 and can slide along the taper surface of defining flange 11, and then realizes
Drag for the expansion of pawl 3 or reduce.
Dragging for and be provided with spring pressure cap 4 by urceolus screw thread between pawl 3 and fishing head 2, spring pressure cap 4 is by shear pin 13
It is connected with mandrel 1.Spring pressure cap 4 and drag between pawl 3 by spring base 7 equipped with spring 6 of giving up.Mandrel 1 is multidiameter, spring base
Conflicting with the cascaded surface of mandrel 1 and be connected in one end of 7, the purpose being arranged such is: spring base 7 is limited in mandrel 1 cascaded surface
Side, prevent spring base 7 from coming off.
By salvaging spring base 9 equipped with salvaging spring 8 between spring base 7 and urceolus 5.The elastic pressure of spring 6 of giving up is big
In the elastic pressure salvaging spring 8.Salvaging spring base 9 is connected with dragging for pawl 3 conflict.
When this blanking plug reclaims fishing tool work, it need to be connected with bumper jar, then by wireline tools by it
It is lowered into appointment position.Make to drag for pawl 3 to contact with the top connection of blanking plug 14.Subsequently by bumper jar this blanking plug of downward jarring,
Now dragging for pawl 3 under the counteracting force of blanking plug 14, after spring 8 is salvaged in compression, the taper surface along defining flange 11 upwards moves
Dynamic.Drag for pawl 3 in this course can shrink, hence in blanking plug 14, now under the elastic force effect salvaging spring 8
Drag for pawl 3 to reset along the taper surface of defining flange 11, thus blanking plug 14 is pinned.Then should by bumper jar upwards jarring
Blanking plug, can salvage taking-up by blanking plug 14.
During this fishing tool is salvaged, needing to give up when tripping out instrument if meeting emergency, needing to strengthen
Jarring force upwards, now bumper jar can pull fishing head 2 and mandrel 1 to cut off shear pin 13, makes spring pressure cap 4 depart from and shears
The restriction of pin 13, spring 6 of then giving up can promote spring pressure cap 4 to move upward, in this mistake under the effect of its own resilient
In journey, spring pressure cap 4 can be pulled by urceolus 5 and drag for pawl 3, drags for after pawl 3 overcomes the elastic force salvaging spring 8 and moves upward, drag for pawl 3 to
In upper motor process, can shrink along the taper of defining flange 11, thus disengage with blanking plug 14, it is achieved give up and (see
Figure of description 5).
This blanking plug reclaims fishing tool compact conformation, easy to use, solves the structure that existing fishing tool has multiple
The problem that miscellaneous and organic efficiency is low, meets the needs of enterprise's production and application.
