Description
Technical field
The utility model relates to last, the special-purpose assembling and disassembling stand of shackle, the particularly spinner assembly of assembling and disassembling stand of a kind of petroleum thread pipe and drilling tool.
Background technology
At present, be used to dismantle, assemble all kinds of oil of maintenance and shelve with the equipment hydraulic detachment that drilling tool, tubing string and downhole tool are threaded, mainly by chassis, support, and the rotating mechanism of upper punch button is formed.Rotating mechanism is the chief component of assembling and disassembling stand.By the chucking mode of its cupboard button device, can be divided into four kinds of patterns, i.e. chain type, ramp formula, cam-type and multiple casing to workpiece.Chinese patent, notification number are 2656612, and name is called " hydraulic detachment is shelved the rotating mechanism that the impact tong bearing connects ".Chuck body and coupling spindle are fixed on the flange both sides, and big footpath bearing and semi-ring are enclosed within on the coupling spindle, and coupling spindle is provided with half circle groove, and semi-ring is set on the bearing upper surface, the interior big footpath of half circle groove, and the bearing support and the bearing (ball) cover of big footpath bearing are fixed on the impact tong stake body.Chinese patent and for example, notification number is 2103633, name is called " tool clamp under the oil well ".Mainly be contained in respectively in the fan-shaped chamber of three off-centre operations in the housing along its off-centre operation cambered surface synchronously that positive and negative transferring clamps or unclamp workpiece (drilling rod, downhole tool) around the center of circle of housing by three fan-shaped block teeth, three block teeth are that cambered surface contacts with workpiece, and clamp automatically, can regulate the size of its clamping force with the size of operation torque automatically, can not skid.These two patents mainly solve the assembling and disassembling stand cupboard button device, and to have a gap big, and supporting capacity is little, when dashing button, spinner running unstable, the shortcoming that application life is short.But when holding workpiece, need change block teeth to the different-diameter workpiece; In addition, in rotating mechanism when work,, initiatively pincers block workpiece respectively with passive pincers, dash button with dashing the button fluid cylinder again, go up, during shackle about about 30 ° of corner, spinner continuously, deficiencies such as inefficiency.
The utility model content
The purpose of this utility model provides a kind of continuous high pulling torque spinner machine, and direct spinner behind the chucking workpiece does not need to dash button; The different-diameter piece-holder is not needed to change block teeth; In addition, during rotating mechanism work, can continuous high pulling torque spinner.Overcome the prior art operation torque and want when big to dash button with fluid cylinder earlier, button is washed back or operation torque open hour again with the shortcoming of the continuous spinner of spinner; The high pulling torque spinner is simple to operation continuously, has improved operating efficiency greatly.
The technical solution adopted in the utility model is: the utility model mainly comprises: gear-box and fixing rotary clamp, adjustable clamp, base, hydraulic control panel and the moment of torsion digital display monitoring part composition that grades.Gear-box adopts and is bolted to base one end.Adjustable clamp is on the guide rail of base, and the adjustable clamp bottom is fixed four roller and sprocket wheel, chain drive.The fluid motor drive sprocket rotate to drive adjustable clamp move left and right on base rail, to adjust the fixedly distance between the rotary clamp and adjustable clamp, to adapt to by the length of spinner workpiece.Fixedly rotary clamp center and adjustable clamp center are on a center line.It is characterized in that: gear-box and fixedly the structure of rotary clamp be: gear box cover is fixed by bolts on the gear housing, and fluid motor and sealing shroud are fixed by bolts on the gear box cover respectively.Fluid motor connects high speed shaft.The high speed shaft of dress is fixed with pinion in the fluid motor driven gear case on the high speed shaft.Pinion and gear wheel engagement.Sealing shroud is fixed on the gear box cover.Hollow shaft is arranged in the sealing shroud, and the hollow shaft other end is fixed with 2-6 chucking fluid cylinder and synchronous valve synchronously.Gear wheel is fixed on the hollow shaft.Between sealing shroud and hollow shaft, have 3 road sealing rings at least, isolate A, B oil inlet passage.2 hydraulic oil channels are arranged on gear box cover, sealing shroud and the hollow axial wall, and two hydraulic oil channels are respectively by between the adjacent 2 road sealing rings.Article 2, hydraulic oil channel arrives the gear housing outer end by hollow shaft respectively.Article 2, the exit, gear housing outer end of hydraulic oil channel is connected with hydraulic line, and the other end of 2 hydraulic lines connects the import and export that tighten fluid cylinder respectively.In the chucking fluid cylinder piston and piston rod are arranged, the end of piston rod is fixed with the clamping block of chucking workpiece.Article 2, in one synchronous valve is housed in the hydraulic oil channel, guarantees that the chucking fluid cylinder is two-way all synchronous.
In order to lower the gear wheel rotating speed, between gear wheel and pinion, can transmit reduction gearing.Be that gear drive becomes multi-stage speed-reducing from the single-stage deceleration.
Continuous high pulling torque spinner machine operating principle:
1, hydraulic control panel provides highly pressurised liquid by the A oil circuit, liquid hydraulic return console in the B oil circuit.Highly pressurised liquid enters chucking liquid cylinder piston end through gear box cover, sealing shroud, hollow shaft and hydraulic line, promotes piston, piston rod and clamping block chucking workpiece.Synchronous valve guarantees that many fluid cylinders are two-way all synchronous.
2, the other end of adjustable clamp fluid cylinder chucking workpiece.
When 3, the fluid motor rotation drove the high speed shaft rotation, pinion drove the gear wheel rotation.Gear wheel drives hollow shaft and the rotation of chucking fluid cylinder, captured workpiece rotation.
4, workpiece one end rotates under the drive of fixing rotary clamp, and the workpiece other end is blocked motionless by adjustable clamp, and the screw thread in the middle of the workpiece is screwed.
5, when the fluid motor rotation drove the high speed shaft opposite spin, workpiece was outwarded winding.
6, provide highly pressurised liquid by the B oil circuit, liquid hydraulic return console in the A oil circuit when hydraulic control panel.Highly pressurised liquid enters chucking liquid cylinder piston rod end through gear box cover, sealing shroud, hollow shaft and hydraulic line, promotes piston, piston rod and clamping block and unclamps workpiece.Can take off workpiece.
7,, can adjust adjustable clamp and the fixing distance between the rotary clamp for making the suitable workpiece of adjustable clamp and the fixing distance between the rotary clamp.Workpiece is adjusted the close fixedly rotary clamp of adjustable clamp more in short-term; When workpiece is longer, adjust adjustable clamp away from fixing rotary clamp.Adjusting distance realizes with fluid motor drive sprocket link chain mechanism.
The beneficial effects of the utility model: the function of high pulling torque spinner machine is to make button or shackle on the tubular workpiece that is threaded continuously, or the antitorque detection of shaft-like workpiece.Adopt chucking fluid cylinder promotion clamping block holding workpiece synchronously, the different-diameter workpiece need not changed block teeth; The high pulling torque spinner has improved operating efficiency continuously; One chucking, a spinner are finished or shackle, and be little to the surface of the work damage, helps the original intensity of maintenance instrument; Simplified operation sequence, the automaticity height; Adjustable clamp moves with sprocket wheel, chain drive, and is simple in structure, can adjust automatically during spinner fixedly that spinner clamps and adjustable clamp between distance; Sealing shroud is reasonable in design, makes the rotary dynamic seal system works reliable, and it is convenient to change; Moment of torsion digital display monitoring system makes operation torque convenient reading, accurate.
