Description
One, technical field
The utility model relates to the lifting type left hand fishing spear that a kind of oil well repairing operation is used.
Two, background technology
The fishing spear that oil well operation is at present used can only be grabbed and be dragged for, very tight as by the thing card, can take off lance when carrying firmly by force, cause and salvage failure, as think that forward or reverse salvaged thing, make it the chucking degree by tightly fluffing, fishing spear does not have positive and negative rotating function again, causes salvaging junk success rate very low.
Three, summary of the invention
The purpose of this utility model provides a kind of lifting type left hand fishing spear, solves that above-mentioned prior art exists because unreasonable structure, causes the problem of salvaging at the bottom of the junk success rate.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of top connection, gland, guide finger, lance bar and slips, it is characterized in that top connection links to each other with lance bar screw thread, and slip sleeve slides up and down in the set guide finger in slips top and the gathering sill set on the lance bar and cooperates on the lance bar; Gland links to each other with the outer round thread in lance bar upper end.
The top connection top and the bottom are provided with box thread, and top links to each other with the fishing string spiral shell, and the bottom is threaded with the lance bar, is provided with tooth on the top connection lower surface.
Lance bar top is made as cylindrical, the bottom is made as taper shape, the upper end is provided with male thread, the center is provided with centre bore, be provided with three strip grooves of angle 120 degree in the middle and upper part, the middle and lower part is provided with three strip grooves of angle 120 degree, the same axis of last low groove, and the bottom is made as and is the conical head of taper up and down.
The slips middle and upper part is made as cylindrical shape, and the upper end is provided with male thread and gland threaded engagement, and the middle and lower part is made as three lobe shapes of angle 120 degree, and the bottom periphery of three lobes is made as zigzag, slides up and down with the groove of lance bar middle and lower part to cooperate; On the slips upper surface, be provided with tooth, with the tooth engagement of top connection lower surface.
Compared with the prior art the utility model has the following advantages:
1, this drags for lance and withdraws from fish and need not rotate and withdraw from, and only needs a handling to regain and drags for lance, has saved rotation and has withdrawed from equipment and the operation of fish.
2, this drags for and can realize under the tooth engagement of lance top connection and slips the rotating and reverse of fish, thereby the fish of chucking is become flexible.
3, this drags for lance under the effect of lance bar slip groove and slips, and it is tight more to carry more card on the engaging fish, the lance phenomenon can not occur taking off.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
1-top connection 2-gland 3-guide finger 4-lance bar 5-slips among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description: the utility model is made up of top connection 1, gland 2, guide finger 3, lance bar 4 and slips 5, it is characterized in that top connection links to each other with lance bar screw thread, slip sleeve slides up and down in the set guide finger in slips top and the gathering sill set on the lance bar and cooperates on the lance bar; Gland links to each other with the outer round thread in lance bar upper end.
When using the utility model, its top connection 1 is connected on the salvaging post, with near turn on pump circulation fish time the under the fishing string, the foreign material at fish place are washed off, slowly transfer again and drag for lance, treat to stop to transfer when weight indicator falls after rise and drag for lance, carry lance bar 4 in the commentaries on classics, slips is under the effect of guide finger 3, slips is motionless not to rotate yet, under the effect of lance bar middle and lower part taper surface, what make the sawtooth of slips 5 lower ends and fish interior week blocks tighter and tighter, is carried moving as fish, carry on then continuing, up to till falling into well inner sleeve or oil pipe and pulling out, if be stuck by fishing string, on carry motionless, transfer to this moment transfers the lance bar, make slips block tighter and tighter with fish under the effect of lance bar middle part cone step, the tooth of the tooth of slips upper surface and top connection lower surface engagement simultaneously can be to fish embodiment back-off, open near the box cupling the stuck point, segmentation is salvaged.
