Abstract
Barrel structure is salvaged on a large scale the utility model discloses one kind, the lower shell being threaded togather including top connection and with top connection, being provided with lower shell can slide slip cap, the upper end of slip cap is threadedly coupled with inner sleeve, spring is provided between slip cap and inner sleeve, the two ends of spring respectively with top connection and slip cap Elastic Contact, be connected with one group of slips on the circumference of slip cap lower end, the outer wall of slips and the inwall sliding contact of fairlead.Compared with traditional fishing socket, the utility model can obtain bigger salvaging scope without frequently changing slips, improve efficiency of construction, reduce drilling cost.Meanwhile, the utility model just eight valve slips are hung on slip cap, can both prevent slips from inadvertently falling off, and the transmission of power between slips and spring can be played again, improve the fishing success ratio of slips.
Description
Technical field
The utility model is related to one kind to salvage barrel structure on a large scale, belongs to underground fishing tool technical field.
Background technology
Slip socket is that the fishing tool for dragging for fish is grabbed from fish external diameter, and it can salvage drill collar, drilling rod, oil pipe, connect
Head, box cupling and other well pipes.The diameter range that conventional slip socket salvages fish is limited, for different-diameter
Fish is, it is necessary to change different fishing slips, simultaneously as underground fish concrete condition is failed to understand, it is therefore desirable to which one kind salvages model
Larger slip socket is enclosed, is used to salvage the fish of different-diameter, so as to reduce the time for making a trip and salvage cost.
Utility model content
The purpose of this utility model is, there is provided a kind of simple structure, easy to use, fishing success ratio are high to beat on a large scale
Dipper structure, has bigger salvaging scope for the more conventional slip socket of the fishing socket, can be for underground fish diameter not
Bright situation, salvages the fish of different-diameter, so as to reduce the time for making a trip and salvage cost.
The technical solution of the utility model：One kind salvages barrel structure on a large scale, including top connection and with top connection screw thread
The lower shell for linking together, is provided with the slip cap that can be slided in lower shell, and the upper end of slip cap connects with interior external threading
Connect, be provided with spring between slip cap and inner sleeve, the two ends of spring respectively with top connection and slip cap Elastic Contact, in cunning
One group of slips, the outer wall of slips and the inwall sliding contact of fairlead are connected with the circumference of dynamic set lower end.
The upper end of the slips is provided with hook, and slips passes through to be hung in the hanging hole on slip cap lower circumferential,
Pawl is provided with the inwall of slips, boss is provided with the outer wall of slips, be provided with boss and fairlead inwall
The sliding bevel of sliding contact.
The section of the boss is dove-tail form, and boss is arranged in the dovetail groove on fairlead inwall, so as to limit boss
Slided in dovetail groove, it is to avoid slips wanders off during salvaging.Therefore, no matter can in the Vertical Well or in horizontal well
Ensure the centerline parallel of slips and cylinder.
The fairlead is fixed by a pin on the inwall of lower shell.
Wear-resistant strip is provided with the outer wall of the slip cap.Need to slide back and forth up and down in use due to slip cap
It is dynamic, therefore the service life that wear-resistant strip is greatly improved slip cap is set on the outer wall of slip cap.
Due to using above-mentioned technical proposal, the utility model has the advantage of：The utility model sets on the outer wall of slips
Boss is equipped with, and the sliding bevel with fairlead inwall sliding contact is provided with boss, so that opening and receive for slips
Contracting provides space, and it is exactly to salvage scope that slips is opened with the diameter range for shrinking.Compared with traditional fishing socket, the utility model
Bigger salvaging scope can be obtained without frequently changing slips, efficiency of construction is improved, drilling cost is reduced.Meanwhile, this practicality
New just eight valve slips are hung on slip cap, can both prevent slips from inadvertently falling off, and can be played between slips and spring again
The transmission of power, improves the fishing success ratio of slips.

Specific embodiment
In order that the utility model purpose, technical scheme and advantage are clearer, below in conjunction with the accompanying drawings and embodiment pair
The utility model is described in further detail.
Embodiment of the present utility model：On a large scale salvage barrel structure as shown in figure 1, including top connection 1 and with top connection 1
The lower shell 9 being threaded togather, being provided with lower shell 9 can slide slip cap 4, on the outer wall of the slip cap 4
Wear-resistant strip 5 is provided with, the upper end of slip cap 4 is threadedly coupled with inner sleeve 3, and spring 2, bullet are provided between slip cap 4 and inner sleeve 3
The two ends of spring 2 respectively with top connection 1 and the Elastic Contact of slip cap 4, eight valves are connected with the circumference of the lower end of slip cap 4
Slips 6, the inwall sliding contact of every piece of outer wall of slips 6 and fairlead 7, the fairlead 7 is fixed on lower shell by pin 8
On 9 inwall.Referring to Fig. 2 and Fig. 3, the upper end of the slips 6 is provided with hook 11, and slips 6 is hung on slip by hook 11
Cover in the hanging hole 13 on 4 lower circumferentials, pawl 14 is provided with the inwall of slips 6, boss is provided with the outer wall of slips 6
10, the sliding bevel 12 with the inwall sliding contact of fairlead 7 is provided with boss 10.Referring to Fig. 4 and Fig. 5, the boss 10
Section be dove-tail form, boss 10 is arranged in the dovetail groove 15 on the inwall of fairlead 7, so that limitation boss 10 is in dovetail groove
Slided in 15, it is to avoid slips 6 wanders off during salvaging.Therefore, no matter can ensure in Vertical Well or in horizontal well
The centerline parallel of slips 6 and cylinder 9.
Operation principle of the present utility model：When the fish of different-diameter touches slips 6, fishing socket, the edge of slips 6 are transferred
Cylinder 9 to rise and open, spring 2 is compressed by slip cap 4, then above carry fishing socket, slip cap 4 is due to by the bullet of spring 2
The effect of power pushes down on slips 6, and slips 6 declines and shrink along cylinder 9, and the pawl 14 on slips 6 nips fish, in continuation
Carry, the sliding bevel 12 on the outer wall of slips 6 is relative with the dovetail groove 15 on the inwall of fairlead 7 to be slided, and makes what slips 6 stung fish
It is tighter, so as to reach the purpose of salvaging.
