Rotary alignment clamping device for shackling-unshackling back-up wrench for workover treatment sucker rod and using method

Abstract

The invention relates to a rotary alignment clamping device for a shackling-unshackling back-up wrench for a workover treatment sucker rod and a using method. According to the technical scheme, the rotary alignment clamping device comprises a rotating base disc assembly, a guide clamping assembly, a lever type stress application assembly, a pull rod type displacement sensor assembly, a rotating power assembly and a control assembly, the rotating base disc assembly comprises an opening base disc and a plurality of rollers, the rollers are installed at the original back-up wrench position of a power wrench, and the opening base disc rotates through the rollers; clamping blocks of the guide clamping assembly move front and back in a guide rail, and the two clamping blocks clamp a spanner square diameter; and clamping sliding blocks are arranged at the front ends of the clamping blocks and can move relative to the clamping blocks. The rotary alignment clamping device has the beneficial effects that the rotary alignment clamping device is mounted on the back-up wrench of the power wrench of the workover sucker rod, is matched with the power wrench of the workover sucker rod for use, issuitable for shackling-unshackling operation on a small-diameter oil pipe, can realize automatic clamping of the sucker rod, improves the efficiency of the workover operation and further achieves automation of workover treatment.

Description

technical field [0001] The invention relates to the field of oil field workover operation equipment, in particular to a rotary aligning and clamping device and a use method of a sucker rod make-up and breakout back tong for well workover operations. Background technique [0002] The traditional workover operation method is mainly manual. After the sucker rod needs to be manually straightened, the sucker rod slips are clamped, rotated and locked to support the entire operation, and as the sucker rod is lifted by the workover hook, The entire sucker rod operation has been completed, but there are problems such as high labor occupation, high labor intensity, poor open-air construction environment in the field, and high safety risks, especially the sucker rod operation is more prominent. The clamping requirements of the sucker rod are very high. The flange surface for clamping the flange of the sucker rod must become a complete flange surface when clamping, and the two half-flan...

Problems solved by technology

After the sucker rod is positioned on the slips, the position of the diameter of the wrench is arbitrary. Manual operation of the sucker rod on and off the power lifting tongs is easy to make on and off the diameter of the wrench, but it is difficult to realize in the automatic operation Power pliers back pliers alignment wrench square diameter on sucker rod shackle
