Abstract
The utility model discloses a novel spiral buckling power pincer, which comprises a lift clip arm and a right clip arm, the pincer mouths of which are provided with power drive rollers which lead to connection of a connecting rod device that connects the left and the right clip arms into a whole and the left and the right clip arms by a left and a right twisting shafts. Both ends of a telescopic device are connected with the left and the right clip arms by the twisting shafts. The utility mode has advantages of reasonable, simple, light and flexible structure, large holding range, reliable clamping and no damage to tubular piles.
Description
Technical field:
The utility model relates in a kind of oil field drilling process, is used for unloading the spinner Power Tong of tubing string screw thread.
Background technology:
Existing spinner Power Tong as drill pipe tong, sleeve pipe Power Tong, generally all has the pincers tooth in binding clip, damage tubing string easily, and complex structure, and volume is big.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and clamping range is big, and reliable clamping is not hindered the novel spinner Power Tong of tubing string.
Technical solution of the present utility model is:
A kind of novel spinner Power Tong, comprise left and right jig arm, it is characterized in that: the jaw place of left and right jig arm is provided with power-actuated roller, the connecting rod device that left and right jig arm is fused is connected with left and right jig arm by left and right twisted axis, and the two ends of a stretching device are connected with the afterbody of left and right jig arm by twisted axis respectively.
Stretching device is hydraulic cylinder, cylinder or air bag.The opening lazy-tongs are set between left and right jig arm.The opening lazy-tongs comprise the suspension bracket that is fixed in the left and right twisted axis, and suspension bracket middle part installs slide bar, the left and right slide block of suit on the slide bar, left and right slide block respectively with the end hinge joint of left and right connecting rod, the other end of left and right connecting rod links respectively on left and right jig arm.Roller driving device is hydraulic pressure or air pressure motor, and the control valve of controlling this motor is the combination valve form that is combined into one with the control valve of controlling stretching device.
The utility model is rational in infrastructure, simple, light and flexible, and clamping range is big, and reliable clamping is not hindered tubing string.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the partial structurtes diagrammatic sketch of opening lazy-tongs.
Fig. 4 is the vertical view of Fig. 3.
Fig. 5 is the schematic diagram of figure combination valve.
The specific embodiment:
A kind of novel spinner Power Tong, comprise left and right jig arm 1,2, the jaw place of left and right jig arm 1,2 is provided with power-actuated two pair rollers 3, the connecting rod device 4 that left and right jig arm 1,2 is fused is connected with left and right jig arm 1,2 by left and right twisted axis 5,6, and the two ends of a stretching device 7 are connected with the afterbody of left and right jig arm 1,2 by twisted axis 8,9 respectively.Connecting rod device 4 can be the adjustable form of conventional screw mandrel, feed screw nut's spacing.
Handle the valve 16 of combination valve, stretching device 7 is shunk, drive left and right jig arm 1,2 and rotate, open clamp-buckle around twisted axis 5,6; After jaw sent into tubing string, handle the valve 15 of combination valve, motor 14 work drive roller 3 rotations, realize screwing or outwarding winding of tubing string screw thread; Control valve 16 shrinks stretching device 7 again, opens jaw, and Power Tong is moved back place's tubing string, promptly finishes a spinner action.
