Description
Technical field
The utility model belongs to oil drilling machine equipment technical field, relates to a kind of device for changing hydraulic slip pincers tooth box.
Background technology
In recent years, along with drilling automation degree is more and more higher, increasing rig is equipped with the mechanized shaftmouth instruments such as hydraulic slip, and the safety of drilling well and efficiency are improved.Hydraulic slip frequently must change the tubing string that pincers tooth box adapts to different size in conventional drilling and casing job.It is too complicated that mechanism changed by conventional hydraulic slips pincers tooth box, and mechanism element is too much, and difficulty of processing is large, and it is low to change efficiency, and safety is bad.
Utility model content
The utility model provides a kind of device for changing hydraulic slip pincers tooth box, to solve in prior art hydraulic slip Conventional mechanisms use all-purpose tool and open hook dismounting efficiency low, slips pincers tooth box lockout mechanism is complicated, the problem that operational reliability, safety are not high.
The technical solution adopted in the utility model is, a kind of device for changing hydraulic slip pincers tooth box, comprises for the lockout mechanism of slips body and the lifting device two parts for clamping tooth box,
The structure of described lockout mechanism comprises fixture block axle, and fixture block axle is threaded connection and is arranged on slips body, and fixture block axle is installed with torsion spring and fixture block, and fixture block axle upper end is set with nut, and slips body is fixed with backing pin, and fixture block is provided with overhanging projection;
The structure of described lifting device comprises shadoof, and shadoof lower end cylindrical is provided with outside thread, keeps to the side along being provided with the internal thread hole matched with shadoof at pincers tooth box.
Device for changing hydraulic slip pincers tooth box of the present utility model, is further characterized in that:
Shadoof upper end is upwards connected with rotating hoisting ring, chain, wire tensioner and screw shackle in turn.
Fixture block overhanging projection contacts with backing pin when turning to predetermined angular, now, and upper along crimping just with pincers tooth box of the inclined-plane cantilever of fixture block.
The beneficial effects of the utility model are, achieve the quick-replaceable of pincers tooth box, lockout mechanism is safe and reliable, and lifting device structure is simple.Package unit is easy to operation, and save the time of put-on and delegated tubing string, operating efficiency significantly improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the lockout mechanism in the utility model;
Fig. 2 is the structural representation of the lifting device in the utility model.
In figure, 1. backing pin, 2. fixture block, 3. nut, 4. torsion spring, 5. slips body, 6. fixture block axle, 7. clamp tooth box, 8. shadoof, 9. rotating hoisting ring, 10. chain, 11. wire tensioners, 12. screw shackles, 13. inclined-plane cantilevers.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of the utility model device is, comprises for the lockout mechanism of slips body and the lifting device two parts for clamping tooth box,
As Fig. 1, the structure of lockout mechanism comprises fixture block axle 6, fixture block axle 6 is threaded connection and is arranged on slips body 5, fixture block axle 6 is installed with torsion spring 4 and fixture block 2, fixture block axle 6 upper end is set with nut 3 for carrying out axial location to fixture block 2, fixture block 2 can rotate around fixture block axle 6 under the twisting force of torsion spring 4, slips body 5 is fixed with backing pin 1, fixture block 2 is provided with overhanging projection, contact with backing pin 1 when the overhanging projection of fixture block 2 turns to predetermined angular be subject to spacing, under this state, the inclined-plane cantilever 13 of fixture block 2 just crimps with the upper edge of pincers tooth box 7, pincers tooth box 7 can not axially be moved, ensure that pincers tooth box 7 is in the lock state.
As Fig. 2, the structure of lifting device is, comprises shadoof 8, shadoof 8 upper end is upwards connected with rotating hoisting ring 9, chain 10, wire tensioner 11 and screw shackle 12 in turn, the rotating hoisting ring 9 that shadoof 8 connects provides rotatably mounted, and rotating hoisting ring 9 top is connected with wire tensioner 11, adjustable length; Shadoof 8 lower end cylindrical is provided with outside thread, keeps to the side along having the internal thread hole matched with shadoof 8 at pincers tooth box 7.
Utility model works process is,
Under normal circumstances, blocked by pincers tooth box 7 by the inclined-plane cantilever 13 of the fixture block 2 on slips body 5, fixture block 2 can not rotate under the constraint of the spacing of backing pin 1 with torsion spring 4, is in pincers tooth box 8 lock-out state.
Lifting device is transferred, shadoof 8 is with being threaded in pincers tooth box 7, the inclined-plane cantilever 13 that while being threaded into, the disk of shadoof 8 squeezes fixture block 2 makes fixture block 2 rotate, overcome torsion spring elastic force and open locking, until the inclined-plane cantilever 13 of fixture block 2 by thorough extruding leave on pincers tooth box 7 along after, upper lifting holding tool, pincers tooth box 7 can easily propose.
Easily put into slips body 5 with shadoof 8 after the pincers tooth box 7 more renewed, new pincers tooth box 7 squeezes fixture block 2 and slips into installation site along slips body 5 dovetail furrow, completes pincers tooth box 7 and changes.Shadoof 8 is connected with rotating hoisting ring 9 by screw thread, the order connected from bottom to top is rotating hoisting ring 9, chain 10, wire tensioner 11, screw shackle 12, the chain length of its composition can be regulated by wire tensioner 11, has adapted to the replacing of the pincers tooth box 7 of different size.
The utility model device can in slips body locking pliers tooth box, and lockout mechanism can be opened fast change pincers tooth box; Easy and simple to handle, regulate simple, reset flexibly, version part is light and handy, good reliability, replacing pincers tooth box efficiency are high, and meets the requirement of HS E and ISO14000.
