Abstract
The utility model relates to a kind of bar class can move back dipper, it is characterized in that: it comprises top connection, mandrel, cylindrical shell, turbine, lock bracket, mandrel leading truck, clamping bolt post, damping frame, damping fin, bailer grab, slips, guide shoe.Described top connection top is connected with drilling rod, and bottom utilizes mandrel to be coaxially connected with cylindrical shell, and described bailer grab is cemented on cylindrical shell by bailer grab stop pin, keeps in touch with lock bracket, controls its opening and closing degree by lock bracket, and installs slips in chute thereon.It is for existing cylinder class fishing tool, comparatively large to the external diameter accommodation of the bar class junk of required salvaging, and can disposable locking junk, and good operability, because not needing turning tool tubing string, is applicable to the light maintenance field operation lacking rotating disc.
Description
Technical field
The utility model relates to a kind of large man's instrument, and particularly a kind of bar class can move back dipper.
Background technology
Trouble of lost tool in hole impact is produced, and need to salvage process, fishing tool manufactures and designs for the feature of different junk.Fishing tool be in well workover construction most widely used general, access times from frequent, application kind and the maximum special tool of specification.Cylinder class fishing tool is one of fishing tool important in various workover treatment.
Utility model content
The utility model is intended to overcome existing cylinder class fishing tool to the poor defect of the change in size adaptedness of junk, provides a kind of bar class and can move back dipper.Its technical scheme adopted is as follows:
Bar class can move back dipper, comprises top connection, mandrel, cylindrical shell, auxiliary stand, turbine, auxiliary stand stop pin, damping spring, thrust bearing, bearing mounting base, bailer grab stop pin, lock bracket, mandrel leading truck, clamping bolt post, damping frame, locking nut, damping fin, bailer grab, slips, guide shoe.Described top connection top is connected with drilling rod, bottom utilizes mandrel to be coaxially connected with cylindrical shell, described auxiliary stand is connected on cylindrical shell by auxiliary stand stop pin, described turbine is arranged between two thrust bearings, described damping spring one end is arranged in the circular trough of damping frame, the other end acts on damping fin, to ensure that damping fin and turbine have suitable pressure, described bearing mounting base is arranged in the middle part of cylindrical shell, for installed thrust bearing, described mandrel leading truck is arranged on cylindrical shell top, and coordinate with mandrel, ensure its axially-movable, described bailer grab is cemented on cylindrical shell by bailer grab stop pin, keep in touch with lock bracket, its opening and closing degree is controlled by lock bracket, and in chute thereon, slips is installed, described guide shoe is arranged on cylinder body bottom, for by bar class junk import tool chamber.Use low discharge circulation fluid for rinsing the top of fish, because damping fin exists frictional force to turbine, produce damping action, turbine non rotating, strengthen the flow of circulation fluid, lock bracket makes the opening and closing degree of bailer grab reduce, and slips is contacted with the external diameter of bar class junk, and produces radial load, now, on carry instrument, slips and bar class junk are stung tightly, can by junk take out realize salvage.When exiting, issued suddenly by drilling tool, thus impact cylindrical shell, now slips is up along the chute of bailer grab, until slips is separated with junk, now upper body drilling tool can exit fish.
Described clamping bolt post and the locking nut threaded engagement be connected on turbine, its low side and lock bracket are connected.Strengthen the flow of circulation fluid, turbine starts to rotate, and drive locking nut to rotate, clamping bolt post and lock bracket produce axially-movable thereupon, and lock bracket makes the opening and closing degree of bailer grab reduce simultaneously.
The utility model tool has the following advantages: comparatively large to the external diameter accommodation of the bar class junk of required salvaging, and can disposable locking junk, and good operability, because not needing turning tool tubing string, is applicable to the light maintenance field operation lacking rotating disc.

1. top connection, 2. mandrel, 3. cylindrical shell, 4. auxiliary stand, 5. turbine, 6. auxiliary stand stop pin, 7. damping spring, 8. thrust bearing, 9. bearing mounting base, 10. bailer grab stop pin, 11. lock brackets, 12. mandrel leading trucks, 13. clamping bolt posts, 14. damping frames, 15. locking nuts, 16. damping fins, 17. bailer grabs, 18. slips, 19. guide shoes.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, bar class can move back dipper, comprises top connection 1, mandrel 2, cylindrical shell 3, auxiliary stand 4, turbine 5, auxiliary stand stop pin 6, damping spring 7, thrust bearing 8, bearing mounting base 9, bailer grab stop pin 10, lock bracket 11, mandrel leading truck 12, clamping bolt post 13, damping frame 14, locking nut 15, damping fin 16, bailer grab 17, slips 18, guide shoe 19.Described top connection 1 top is connected with drilling rod, bottom utilizes mandrel 2 to be coaxially connected with cylindrical shell 3, described auxiliary stand 4 is connected on cylindrical shell 3 by auxiliary stand stop pin 6, described turbine 5 is arranged between two thrust bearings 8, described damping spring 7 one end is arranged in the circular trough of damping frame 14, the other end acts on damping fin 16, to ensure that damping fin 16 and turbine 5 have suitable pressure, described bearing mounting base 9 is arranged in the middle part of cylindrical shell 3, for installed thrust bearing 8, described mandrel leading truck 12 is arranged on cylindrical shell 3 top, and coordinate with mandrel 2, ensure its axially-movable, described clamping bolt post 13 and locking nut 15 threaded engagement be connected on turbine 5, its low side and lock bracket 11 are connected, described bailer grab 17 is cemented on cylindrical shell 3 by bailer grab stop pin 10, keep in touch with lock bracket 11, its opening and closing degree is controlled by lock bracket 11, and in chute thereon, slips 18 is installed, described guide shoe 19 is arranged on bottom cylindrical shell 3, for by bar class junk import tool chamber.
During salvaging, the external diameter footpath that pawl internal diameter is greater than bar class junk is dragged in the bottom of bailer grab 17, now use low discharge circulation fluid for rinsing the top of fish, because damping fin 16 pairs of turbines 5 exist frictional force, produce damping action, turbine 5 non rotating, be attached thereto locking nut 15, clamping bolt post 13 and lock bracket 11 keep motionless, guide shoe 19 auxiliary under, during bar class junk instrument inner chamber, strengthen the flow of circulation fluid, turbine 14 starts to rotate, drive locking nut 15 to rotate simultaneously, clamping bolt post 13 and lock bracket 11 produce axially-movable thereupon, lock bracket 11 makes the opening and closing degree of bailer grab 17 reduce, slips 18 is contacted with the external diameter of bar class junk, and produce radial load, now, on carry instrument, slips 18 and bar class junk are stung tightly, junk can be taken out and realize salvaging.When exiting, cannot pull out, when need exit dipper, issued suddenly by drilling tool once fish is stuck, thus impact cylindrical shell 3, now slips 18 is up along the chute of bailer grab 17, until slips 18 is separated with junk, now upper body drilling tool can exit fish.
