Abstract
The utility model relates to a linkage power tong device which is used for loading and unloading a pipe column (or a bar column) screw thread for the workover operation in an oilfield. The utility model comprises a pair of main tongs, a pair of back tongs and a plurality of auxiliary members. The pair of main tongs is supported by the pair of back tongs and the pair of main tongs can float up and down corresponding to the pair of back tongs. A hanger rod is fixed on the pair of back tongs, and the pair of main tongs and the pair of back tongs are both driven by a hydraulic force. A hand-operated direction valve which operates the pair of main tongs can cause the pair of main tongs and the pair of back tongs to act coordinately, and the operation of the pair of back tongs dispenses with manual intervention. The utility model not only can be moved as an integral body but also can be moved as two parts.
Description
The utility model is in oil well repairing operation, is used for unloading a kind of by the main pincers that surge of oil well pipe post (or roofbolt) screw thread, the coordinated type Power Tong device of hydraulic back pincers combination.
In existing Power Tong, back-up tong is supporting with main pincers as an annex, during use, will lead pincers earlier and be suspended to well head, back-up tong is suspended on below the main pincers again.Work finishes, and must earlier back-up tong be shed, and main pincers just can be put into ground.The clamping force of back-up tong is a kind of self-tightening type mechanical force that is produced by self structure, can not give tight., must be buckled in back-up tong on the box cupling by manpower earlier when unloading screw thread last, just can start main pincers worker then and do.Owing to do not give tight power, it clamps performance and is restricted, and when main pincers change the spinner direction, must turn over turnback to back-up tong with manpower.In addition, because structure is limit, when the clamping diameter range changed greatly, also will adjust installation dimension or renewal part could be suitable for.As the power tubing tongs of U.S. BJ-Hughes Worktools Inc. production and the power tubing tongs and the back-up tong of back-up tong and the production of present domestic manufacturer all is this form.Because the existence of the problems referred to above, in the supporting use of main pincers back-up tong, installation and operation are all wasted time and energy bothersome, use inconvenience.
The purpose of this utility model is to provide a kind of leading to clamp the coordinated type Power Tong device of combining with back-up tong.By the main pincers of back-up tong support.Back-up tong clamps with fluid power and unclamps.Handle the hand-operated direction valve on the main pincers, can realize main pincers and back-up tong coordination, remove in the course of work artificial dried the giving to back-up tong fully from, thereby make the Power Tong device easy for installation, chucking is reliable, and it is time saving and energy saving that manipulation is got up.
Task of the present utility model is finished as follows: with reference to accompanying drawing 1, coordinated type Power Tong device is by the main pincers (1) that surge, hydraulic back pincers (4), pillar guide rod (2) (7), spring (3) (8), suspension rod (10) and back-up tong hydraulic circuit (6) are formed.The fulcrum of pillar guide rod is supported main pincers (1) by the spring on the pillar guide rod (3) (8) on hydraulic back pincers (4), the pillar guide rod (2) on the binding clip plays a part to connect, supports and guiding is slided.Pillar guide rod (7) on the pincers tail also bears the countertorque between main pincers and back-up tong except that above-mentioned effect.Main pincers (1) are pressed on the spring (3) (8), can fluctuate along the pillar guide rod with respect to back-up tong (4), make it last when unloading tubing string (or roofbolt), and main pincers moving up and down in company with oil pipe (or beam hanger).The bottom of suspension rod (10) is fixed on the back-up tong (4), and top can connect with the suspension wire rope.Screw-casing (9) center line of suspension rod upper end is on the central plane of main pincers.Rotate screw-casing (9) and can regulate the suspention center of gravity in front and back.With reference to accompanying drawing 2, hydraulic back pincers is mainly by back-up tong main body (15), Hubei Province plate (11) (18), connecting rod (13) (16), rotating shaft (12) (17), oil cylinder compositions such as (14).Hubei Province plate (11) (18) can translation in the square hole of back-up tong main body (15), connecting rod (13) (16) links on back-up tong main body (15) by rotating shaft (12) (17), one end of connecting rod (13) (16) respectively with Hubei Province plate (11) (18) hinge joint, the other end respectively with the two ends fulcrum hinge joint of oil cylinder (14).Two Hubei Province plate holders were right after hoop when oil cylinder piston stretched out, and during the oil cylinder piston withdrawal, Hubei Province plate unclamps box cupling, and the two-position four-way valve (5) in the back-up tong hydraulic circuit (6) is fixed on the back-up tong main body (15).With reference to accompanying drawing 3, the A of the two-position four-way valve (5) in the back-up tong hydraulic circuit (6), the import and export of B oil inlet and outlet and oil cylinder (14) link, the p of valve, the o oil inlet and outlet joins with the oil inlet and outlet that main pincers are gone up oil motor, and promptly the back-up tong hydraulic circuit is subjected to the hand-operated direction valve control of main pincers (1).When two-position four-way valve (5) when being in a certain via positions, main pincers (1) are just changeing goes up button, and back-up tong (4) clamps box cupling; Main pincers (1) counter-rotating resets to breach, and back-up tong (4) unclamps box cupling.When two-position four-way valve (5) is in another via positions, main pincers (1) counter-rotating shackle, back-up tong (4) clamps box cupling; Main pincers (1) are just changeing and are resetting to breach, and back-up tong (4) unclamps box cupling.
During work, push coordinated type Power Tong device to oil well pipe (or roofbolt), handle the hand-operated direction valve of main pincers, because the starting pressure of main pincers oil circuit is big, oil stream is full of oil cylinder earlier, make back-up tong clamp box cupling earlier with certain tight power of giving, main subsequently pincers beginning spinner, along with the increase of rotation torque, oil pressure raises, simultaneously the clamping force of back-up tong also increases in proportion, till tightening or unclamping screw thread.Work finishes, and handles the reverse oil supply of hand-operated direction valve of main pincers, and back-up tong unclamps box cupling earlier, and main subsequently pincers reset to breach.Can whole migrate during resettlement, also main pincers can be taken off the resettlement of branch two bodies from the pillar guide rod.
