Abstract

The utility model discloses multi-functional power tongs, which comprise a main tong and a back tong, wherein the main tong is connected with the back tong by four connecting rods and corresponding lifting mechanisms; each connecting rod and the corresponding lifting mechanism are respectively provided with a main tong lug plate connected with one end of the connecting rod, the other end of the connecting rod is connected with a sliding sleeve by a pin shaft, the sliding sleeve is sheathed on an upright connected with the back tong and is connected with the end of a piston rod of a lifting hydraulic cylinder, the hydraulic cylinder is arranged in a hole of the upright, and the cylinder barrel base of the hydraulic cylinder is arranged on a gland connected with the back tong. The multi-functional power tongs have reasonable structure, high operating efficiency and safe and reliable work.

Description

The multifunction dynamic pincers
Technical field:
The utility model relates in a kind of oilfield drilling well or the workover treatment, is used for unloading drilling rod, bores very, the Power Tong of pipe screw thread such as sleeve pipe.
Background technology:
Because the structure of drilling rod, sleeve pipe is different with job parameter, all need to adopt the Power Tong of two kinds of different structures to satisfy the job requirements of drilling rod (boring very) and sleeve pipe, promptly usually said low, the poor stability of drill pipe tong and casing strength respectively all the time.And general Power Tong distance between about master's pincers and the back-up tong when all adopting spring to regulate buckle (or shackle) operation, its shortcoming is that adjustable range is lacked, poor reliability.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and operating efficiency height, safe and reliable multifunction dynamic clamp.
Technical solution of the present utility model is:
A kind of multifunction dynamic pincers, comprise main pincers, back-up tong, it is characterized in that: main pincers link together by four connecting rods and corresponding elevating mechanism and back-up tong, each connecting rod and corresponding elevating mechanism have the main Qianer plate that is connected with an end of connecting rod, the other end of connecting rod is connected with sliding sleeve by bearing pin, and sliding sleeve is enclosed within on the pillar that links together with back-up tong, and sliding sleeve is connected with the tailpiece of the piston rod of lifting fluid cylinder, fluid cylinder is contained in the hole of pillar, on the gland that the cylinder barrel seat is arranged on back-up tong is connected of fluid cylinder.
The utility model is rational in infrastructure, operating efficiency height, safe and reliable; Main pincers link together with back-up tong by connecting rod and elevating mechanism, main pincers both can with respect to about back-up tong, front and back float, again can be with respect to the back-up tong oscilaltion, under the hydraulic system effect, the last button of main pincers or shackle and decline or vertical motion realization link simultaneously.Can carry out Long-distance Control to the clamping action of back-up tong, rotation, shift speed change and the lifting action of main pincers by control system, also can carry out Long-distance Control the torque wrench moment of Power Tong.By changing binding clip jaw specification, regulating the distance between main pincers and the back-up tong, adjust the torque wrench moment of Power Tong, applicable to drilling rod, bore very, the operation of multiple oil pipe such as sleeve pipe.
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 A-A view of Fig. 1.
Fig. 4 is a hydraulic system principle figure.
The specific embodiment:
A kind of multifunction dynamic pincers comprise main pincers 1, back-up tong 2, and main pincers adopt motor 6 to drive, and drive binding clip 7 rotations through gear 5 and reducing gear, realize clamping and rotation oil pipe; Back-up tong is driven by clamping cylinder 4 and clamps pipe, cooperates main pincers that the pipe screw thread is gone up button or shackle operation.Main pincers link together with back-up tong by four connecting rods and corresponding elevating mechanism 3, each connecting rod and corresponding elevating mechanism have the main Qianer plate 14 that is connected by bearing pin 16 with an end of connecting rod 17, the other end of connecting rod is connected with sliding sleeve 13 by bearing pin 15, sliding sleeve is enclosed within on the pillar 12 that links together with back-up tong, sliding sleeve is connected with the tailpiece of the piston rod of lifting fluid cylinder 11, fluid cylinder is contained in the hole of pillar, and the cylinder barrel seat of fluid cylinder is arranged on the gland 10 that is connected with back-up tong.Also has control system 8 among the figure.
Adopt multiple directional control valve 20 control the action of main pincers motor, lift cylinders, clamping cylinder, gear shift cylinder respectively in the hydraulic system, on detain overflow valve 9 and be used for regulating the main torque wrench moment that clamps, also can carry out Long-distance Control to said elements by control system.The wherein lifting of the integrated valve block 18 positive and negative rotation (promptly going up button or shackle) that can make main pincers motor and main pincers or rise and realize interlock, promptly when on the Power Tong during button operation, main pincers descend, distance shortening between the pincers up and down; And when Power Tong shackle operation, main pincers rise, distance elongation between the pincers up and down.Because lifting hydraulic cylinder can guarantee to have enough adjustable ranges between main pincers and back-up tong are up and down, thereby satisfy the disposable requirement of going up button or shackle of pipe screw thread.
