Abstract
The utility model discloses an automatic feeding device for power head breakout bushes in physical exploration drilling rigs, comprising a breakout bush, a rolling wheel, a shift fork post, a bracket, a hydraulic cylinder and a manual directional valve; wherein, the breakout bush, the rolling wheel, the shift fork post, the bracket, the hydraulic cylinder and the manual directional valve are connected orderly. When in use, the original hydraulic system of the drilling rig or an air path system is applied as the power source; operation of the manual directional valve makes the piston of the hydraulic cylinder flexible and promotes the shift fork post to rotate, so that the breakout bush is driven by the rolling wheel arranged on the shift fork post to slide on the drilling rod coupling of the power head to finish operation of disassembly of the drilling rod.
Description
Affiliated technical field
The utility model relates to one of affiliated principal assembly of unit head of a kind of geophysical exploration rig, and the physical prospecting drill power head shackle casing auto-feeder of dismounting drilling rod is applicable to the physical prospecting drillng operation especially automatically.
Background technology
More advanced physical prospecting rig is to rely on the fluid motor-driven unit head to realize rotatablely moving at present, simultaneously by another motor drive chain wheel shaft, straight line moves to finish and promotes and pressurization about the drive chain, and two kinds of motions lump together, and have just formed normal drilling process.In the normal drilling process, shackle casing does not engage with following drilling rod all the time, and the screw thread between the moment of torsion dependence drilling rod transmits.Need drilling rod is taken out from the shaft bottom after getting into predetermined well depth, drilling rod can only singlely be dismantled.Shackle process is as follows:
1, blocks the top driving key of the drilling rod that needs dismounting with slips, make the unit head counter-rotating, to unload the end that pine links to each other with the unit head tool joint, put down shackle casing then, allow the top driving key of drilling rod enter in the keyway of shackle casing, unclamp slips, drilling rod is risen to proper height;
2, block second top driving key with slips, make the unit head counter-rotating, moment of torsion passes to drilling rod by shackle casing, can reach like this lower thread is connected the purpose of laying down;
When 3, unit head descends, manually drilling rod is moved to correct position.Regain shackle casing, staff is held drilling rod, the unit head counter-rotating, and screw thread is laid down fully until the upper end.
All the time, shackle casing is to rely on a buckle chainlet to be fixed on the loose-proof sleeve of unit head, during dismounting drilling rod by manually sliding up and down shackle casing.This kind method is inefficiency not only, and time-consuming, take people, effort.When having a small amount of mud to cling in the cover, may shackle casing be slided, can only make it loosening, cause the shackle casing distortion after the time is long easily and necessary the replacing with the method for knocking with hand, in addition, because directly contact, staff comes to harm easily, has suitable potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of device that makes the auto-feed of physical prospecting drill power head shackle casing, its employing hydraulic pressure (or air pressure) can be as power, utilize the flexible shackle casing that makes of fluid cylinder (or cylinder) to slide up and down, the process of dismounting drilling rod is finished quickly and safely.
The utility model is achieved in that in the hydraulic system (or air-channel system) at former rig and goes out one road hydraulic pressure (or air pressure) power source, for the shackle casing auto-feeder provides power, bracing frame is fixed on the lower surface of unit head casing, the middle part of shifting fork bar is attached thereto, its other two ends then link to each other with roller with the liquid cylinder piston bar respectively, roller is embedded on the slide rail of shackle casing, and the other end of fluid cylinder is fixed on the bracing frame and constitutes; Shackle casing can slide in the unit head tool joint, closes or opens feed flow by the hydraulic manual reversal valve and make the piston drive piston rod of fluid cylinder flexible, and the interlock shackle casing slides on central tube, realizes the shackle of drilling rod.When needing work, the operation hand-operated direction valve is controlled the piston reduction of fluid cylinder, makes piston rod drive the rotation of shifting fork bar, and interlock shackle casing sliding up and down in the unit head tool joint carried out the dismounting drilling rod operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a concrete structure schematic diagram of the present utility model.
Fig. 2 is a hydraulic schematic diagram of the present utility model.
Accompanying drawing number is: 1, shackle casing, 2, roller, 3, shifting fork bar, 4, bracing frame, 5, fluid cylinder, 6, hand-operated direction valve.
The specific embodiment
Among Fig. 1, bracing frame (4) is fixed on the lower surface of unit head casing, and the middle part of shifting fork bar (3) is attached thereto, and its other two ends then link to each other with roller (2) with fluid cylinder (5) respectively, and roller is embedded on the slide rail of shackle casing (1).The other end of fluid cylinder or cylinder (5) is fixed on the bracing frame.Shackle casing can slide in the unit head tool joint.
Among Fig. 2, dynamical system is mainly connected to form by pipeline by hand-operated direction valve (6) and fluid cylinder (5).When the needs shackle casing moved, operation hand-operated direction valve (6) made the piston of fluid cylinder flexible, drives shifting fork bar (3) rotation, moved up and down by pulley (2) the promotion shackle casing that is installed on the shifting fork bar (3).Because shackle casing can rotate along with the unit head tool joint, thus in order to reduce friction and to wear and tear, do not adopt shifting fork bar (3) directly to contact with shackle casing (2), and adopt roller to contact with shackle casing.
Claims (1)
1. the physical prospecting drill power head shackle casing auto-feeder of a physical prospecting drilling well, it is characterized in that: bracing frame is fixed on the lower surface of unit head casing, the middle part of shifting fork bar is attached thereto, its other two ends then link to each other with roller with the liquid cylinder piston bar respectively, roller is embedded on the slide rail of shackle casing, and the other end of fluid cylinder is fixed on the bracing frame and constitutes; Shackle casing can slide in the unit head tool joint, closes or opens feed flow by the hydraulic manual reversal valve and make the piston drive piston rod of fluid cylinder flexible, and the interlock shackle casing slides on central tube, realizes the shackle of drilling rod.
