The oil pipe of oil field shaft mouth, sleeve pipe, drill rod thread upper, unload and smash, use a kind of effective Power Tong, it can make the convenient disassembly that is threaded of above-mentioned tubing string.Traditional oil field tubulars detain on once with Power Tong or when the shackle end of job, the binding clip clamp mechanism being arranged on binding clip revolving body need to be returned to home position (the centering position of binding clip), facilitates tubing string to pass in and out, and then carries out next endowel operation; Conversion on often needing in the time of operation in addition between button and shackle direction, therefore a backing pin is generally set on binding clip revolving body, a resetting shaft is set on caliper, reset spindle nose has the deep-slotted chip breaker of a containing backing pin, in the time that backing pin enters into the deep-slotted chip breaker of resetting shaft, it is just in time the home position of binding clip revolving body; And to go up, shackle when conversion, only need to be resetting shaft Rotate 180 degree angle, make the direction of deep-slotted chip breaker and opposite direction before, backing pin can be rotated round about, in realization, the conversion of shackle.This transfer process is normally realized by switching resetting shaft manually, and it is not suitable with long-range or automatic job, thereby needs a kind of mechanism that can the rotation of Long-distance Control resetting shaft backing pin is resetted, and could realize, the automatic conversion of shackle.
Summary of the invention
The utility model provides a kind of Power Tong hydraulic control backing pin resetting-mechanism, promotes reseting gear axle steer by tooth bar swing-type cylinder, realizes Remote Hydraulic control object.
To achieve these goals, the utility model is implemented by the following technical programs: a kind of Power Tong hydraulic control backing pin resetting-mechanism, comprise caliper, binding clip revolving body, backing pin, reseting gear axle, tooth bar swing type fluid cylinder, Displaying Meter, backing pin is arranged on binding clip revolving body; Reseting gear axle lower end by bearings in caliper, its external diameter is provided with gear, the other end is provided with and contains arc groove, when backing pin on rotation binding clip revolving body enters into the containing arc groove of reseting gear axle, be the home position of clamp mechanism, 180 ° of forward and reverse spinning reduction gear shafts, can realize on Power Tong, the conversion of shackle; Tooth bar swing-type cylinder comprises oil cylinder cover, cylinder sleeve, piston rod, tooth bar, stop screw, and stop screw is located on caliper, the circular-rotation of restriction cylinder sleeve, and Displaying Meter is arranged on the end of tooth bar swing-type cylinder, it is characterized in that:
Cylinder sleeve and caliper in described tooth bar swing-type cylinder are fixed;
Described reseting gear axle external diameter is provided with gear, and the tooth bar in its wheel and rack swing-type cylinder is meshed;
Piston rod in described tooth bar swing-type cylinder is two rods, it can be split type, also can be all-in-one-piece, if the tooth bar in split type tooth bar swing-type cylinder is placed between two rods, if the tooth bar in all-in-one-piece tooth bar swing-type cylinder is placed on the piston external diameter between two rods;
Described two go out outside the extended oil cylinder cover end face of rod end;
Described two rod rod ends contact with the contact on Displaying Meter.
When Power Tong is changed between upper, shackle, to tooth bar swing-type cylinder fuel feeding, oil cylinder inner piston rod promotes tooth bar and moves, and drives reseting gear axle to rotate, upper, shackle conversion that reseting gear axle Rotate 180 degree is realized; By two go out rod end stretch out the end face of oil cylinder cover, can see intuitively tooth bar position, thereby judgement is position on the buckle or shackle position now, and Displaying Meter also can be set, two go out rod end and Displaying Meter contact, can show button or shackle position; Stop screw can prevent that cylinder sleeve from rotating and the gear of reseting gear axle lower end is collided.
The utility model promotes reseting gear axle by tooth bar swing-type cylinder and realizes and turning to, thereby reaches the object of Remote Hydraulic control, have simple in structure, handled easily, the advantage such as safe and reliable.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is that master of the present utility model looks broken section structural representation;
Fig. 2 is A-A cross section sectional structure schematic diagram in Fig. 1 (tooth bar swing-type cylinder sectional view).
In Fig. 1,2: 1 caliper, 2 binding clip revolving bodies, 3 backing pins, 4 reseting gear axles, 401 contain arc groove, 402 gears, 5 bearings, 6 tooth bar swing-type cylinders, 7 oil cylinder covers, 8 cylinder sleeves, 9 piston rods, 901 tailpieces of the piston rod, 10 tooth bars, 11 stop screws, 12 Displaying Meters.
Detailed description of the invention
As shown in Figure 1, 2, backing pin 3 is arranged on binding clip revolving body 2, and reseting gear axle 4 and tooth bar swing type fluid cylinder 6 are arranged in caliper 1; Reseting gear axle 4 one end are provided with the containing arc groove 401 that can contain backing pin 3, and external diameter is provided with gear 402; Backing pin 3 is subject to the containing arc groove 401 of reseting gear axle 4 one end spacing; One end gear 402 of reseting gear axle 4 engages with tooth bar swing-type cylinder 6 upper racks 10, and reseting gear axle 4 lower ends are supported on caliper 1 by bearing 5.Tooth bar swing-type cylinder 6 comprises oil cylinder cover 7, cylinder sleeve 8, piston rod 9, tooth bar 10, stop screw 11, and stop screw 11 is located on caliper 1, and stop screw 11 limits the circular-rotation of cylinder sleeve 8, the end face of the extended oil cylinder cover 7 of tailpiece of the piston rod 901.Displaying Meter 12 is arranged on tooth bar swing-type cylinder 6 ends, and its contact contacts with tailpiece of the piston rod 901.
