Abstract

An iron roughneck is a tubular torsion clamp for oil filed, and overcomes the defects existing in other technique. The iron roughneck is composed by connecting a collapse buckle clamp, a spanner and a telescopic arm. The upper clamp body and lower clamp body of collapse buckle clamp are hinged and connected through an upper U-shaped rotation ring and a lower U-shaped rotation ring. The upper clamp body and the lower clamp body are respectively provided with a U-shaped groove. The left side and right side of U-shaped groove are symmetrically distributed with a clamping oil cylinder. The piston rod of clamping oil cylinder is connected with a dental plate fixing block. The cylinder is articulated with the clamp body framework. The clamp dental plate is fixed on the upper clamp body and the lower clamp body. The piston rod end of collapse buckle oil cylinder is articulated on the upper clamp body. The rod-free chamber is articulated on the lower clamp body. A screwing roller of spanner is articulated on the linkage brackets at the two sides. The fixed beam is articulated on the back side of linkage frame. A guiding connecting rod is fixed on the fixed beam and the front arm of linkage frame. On the supporting frame, the auxiliary plate of supporting arm, the intermediate connecting plate and the chain plate are articulated. The lifting vertical post is fixed on the rotating chassis of telescopic arm and the lifting hydraulic cylinder.

Description

Iron driller

One, technical field:

The utility model relates to a kind of oil field tubing string torsion tonger, especially iron driller.

Two, background technology:

Various types of iron driller has been equipped with and has been used in oil well drilling process and oil pipe control operation process, but common shortcoming is: collapse clasp forceps and collapse tight and to collapse out the instantaneous pipe dimensions of easily skidding, being suitable for few; Spinner pincers often need lubricated, screw roller and the central axis of tubing string are determined inaccurate, and it is inconvenient to unload roll change, and telescopic arm is adjusted in the jaw motion, height and the bad accurate assurance of jaw position.

Three, summary of the invention:

Order of the present utility model provides a kind of automaticity height, clamp firmly, wide region (adapt to from 2 7/8-11 drilling rods "; heavy weight drill pipe; drill collar; crossover sub; sleeve pipe) iron driller; it has overcome the shortcoming that other technology exists, the purpose of this utility model is to realize like this, it is by collapsing clasp forceps, the spinner pincers, telescopic arm is formed by connecting, collapsing the upper clamp of clasp forceps and two calipers of lower clamp is linked together by U type rotating ring twisting up and down, upper clamp and lower clamp respectively have a U-lag, U-lag the right and left clamping cylinder that is symmetrically distributed, the clamping cylinder piston rod connects the dental lamina fixed block, cylinder barrel and caliper skeleton are hinged, the pincers dental lamina is fixed on upper clamp and the lower clamp, collapsing button oil cylinder piston rod end is hinged on the upper clamp, rodless cavity is hinged on the lower clamp, spinner pincers screw roller by bolted splice on the interlock frame of both sides, clamped beam is hinged on the rear side of interlock frame, and guide link is fixed on clamped beam and the interlock frame forearm; On support arm, support arm subplate, middle web and carrier bar are articulated and connected, and lifting column is fixed on telescopic arm swivel base and the lifting hydraulic cylinder.

During work, power is provided by hydraulic system, jaw has a coaxial U-lag can hold and pass through tubing string, back-up tong is held lower end first endowel tightly, revolve brank and hold first drilling rod of upper end second endowel junction button rotation tightly, second drilling rod inserted in first drilling rod attachment plug to be connected in the pipe collar and tightens or dismantle, collapsing clasp forceps provides necessary going up to detain and shackle torsion for the connection between the tubing string, back-up tong is to use promptly the time, and the spinner pincers promptly and place tight intact button or unsnatch connection between the drilling rod of button; Because the iron driller that uses is adjusted to relatively difficulty of desired location at present, the parallelogram telescopic arm has solved this problem effectively, just with the flexible operation of support arm, can not produce the position that the outage back arm falls or leaves original elongation during work, injure personnel or destruction equipment.

The beneficial effects of the utility model are, design a kind of automaticity height, clamp firmly, the oil field of wide region is with mobile drilling well tubing string torsion pincers tonger, and the tubing string that is suitable for more diameters is increased work efficiency, the saving manpower.
