Abstract
The utility model discloses a side window hinge fisher. The side window hinge fisher is structurally characterized by being a steel body formed by connecting an upper joint and a hollow cylinder body. An inverted cone is arranged on the top of the hollow cylinder body, symmetrical window holes and hinge clip opening windows are arranged on the wall surface of the hollow cylinder body, the inner side of the upper port of each window hole is an inclined plane with arc, a reset spring and a hinge tongue are fixedly pinned on the lower part in each hinge clip opening window, two side walls are inclined, and the bottom of the hollow cylinder body is provided with inner chamfers. The fisher is easy to operate and reliable in performance, solves the problem about well drop fishing of test instruments, and save economic loss for China.
Description
Technical field
The utility model relates in the testing well process, the tester a kind of fishing tool behind the well that falls.
Background technology
In oil gas well surveying examination process, generally adopt piano wire to connect the tester G.I.H and carry out the admission of pressure, temperature data.But operate reasons such as the improper or hole condition of winch owing to the employee, cause the piano wire fracture, the tester well accident that falls happens occasionally.The instrument well accident that falls not only can cause direct economic loss, and the dynamic monitoring information of this well can't be enrolled.
Summary of the invention
In above-mentioned oil gas well surveying examination process, there is the fall problem of well of tester, the purpose of the utility model is to provide a kind of side window loose-leaf fisher.This device adopts the principle of semi-open type loose-leaf; When salvaging the well instrument; Through back-moving spring and the loose-leaf tongue in the set loose-leaf binder openning of this device; Rope socket head chucking is locked, and the fracture steel wire head stretches out from fenestra or loose-leaf binder openning on the rope socket head, thereby the well surveying test instrument that will fall is pulled out.
The purpose of the utility model is to accomplish like this:
A kind of side window loose-leaf fisher, the steel body that is formed by connecting for top connection and hollow cylinder body.The hollow cylinder bodies top is provided with inverted cone; Wall surface has symmetrical fenestra and loose-leaf binder openning, and fenestra inboard suitable for reading is the inclined-plane of band circular arc, and the below steady pin is equipped with back-moving spring and loose-leaf tongue in the loose-leaf binder openning; The two side is the inclined-plane, and interior chamfering is arranged at the hollow cylinder bottom.
The advantage of the utility model and the beneficial effect of generation are:
1, the utility model is novel in design, delicate structure.The loose-leaf binder openning is through interior back-moving spring and the loose-leaf tongue that is located on the steady pin; In the loose-leaf binder openning under the effect of back-moving spring compressive force; Rope socket head chucking is locked; The fracture steel wire head stretches out from fenestra or loose-leaf binder openning on the rope socket head, on carry piano wire and can pull the well instrument out.The salvaging process is not damaged instrument in the well, and the instrument of pulling out can continue to use.Time saving and energy saving, economical and practical.
2, in April, 2011, the utility model first Application in fishing has obtained success, and by in May, 2012, fall well five times of tester is successfully salvaged five times, for company has retrieved nearly 500,000 yuan economic loss.
Description of drawings
Fig. 1 is the utility model partial sectional view.
Fig. 2 is Figure 1A-A ' sectional schematic diagram.
The specific embodiment
Shown in Fig. 1-2; A kind of side window loose-leaf fisher is the steel body that top connection 1 and hollow cylinder body 2 are formed by connecting, and hollow cylinder body 2 tops are provided with inverted cone 8; Wall surface has symmetrical a pair of 15mm * 70mm fenestra 3 and a pair of 20mm * 60mm loose-leaf binder openning 4; Fenestra 3 inboards suitable for reading are for the inclined-plane of band circular arc, and are parallel with the cone face, on the steady pin 5 of below back-moving spring 6 and loose-leaf tongue 7 are housed in the loose-leaf binder openning 4; The window two side is the inclined-plane, and interior chamfering 9 is arranged at hollow cylinder body 2 bottoms.
During use, side window loose-leaf fisher is connected the below of weighted lever, utilizes piano wire G.I.H to junk top of fish position; Chamfering 9 guides to junk top rope socket head in the hollow cylinder body 2 in the device; Under the effect of weighted lever gravity, the back-moving spring 6 and loose-leaf tongue 7 in the compression loose-leaf binder openning 4 opened on the rope socket crown, when the rope socket head passes through back-moving spring 6 and loose-leaf tongue 7; Back-moving spring 6 resets; Loose-leaf tongue 7 locked rope socket heads, then, on carry piano wire and can pull the well surveying test instrument out.If the junk top leaves a small amount of steel wire head, but cone 6 guiding steel wire heads then pass from fenestra 3 or loose-leaf binder openning 4, no longer hinder fisher catching to the rope socket head.
