Abstract

The invention discloses equipment for oil pipe drilling. The equipment comprises a support, a supporting shaft, a drive mechanism, a supporting plate, multiple clamping portions and a drilling portion. The supporting shaft is rotationally connected with the support. The drive mechanism is used for driving the supporting shaft to rotate. The supporting plate is mounted on the supporting shaft. Themultiple clamping portions are evenly distributed with the supporting shaft as the center. Each clamping portion comprises a mounting plate, a screw, two sliding blocks and multiple clamping units, and each mounting plate is connected with the supporting plate and is provided with a sliding groove. Each screw and the corresponding mounting plate are rotationally connected, and the length directionof each screw is parallel to that of the corresponding sliding groove. Each screw is provided with two thread areas, and the rotating directions of threads of the two thread areas of each screw are opposite. The two sliding blocks of each clamping portion are in threaded connection with the two corresponding thread areas correspondingly and are in sliding connection with the corresponding slidinggroove. The multiple clamping units of each clamping portion surround the periphery of the corresponding screw. Each clamping unit comprises a clamping plate and two connecting rods, and each clamping plate is hinged to the two corresponding sliding blocks through the two corresponding connecting rods. The drilling portion is used for oil pipe drilling machining.

Description

technical field [0001] The invention relates to the technical field of oil pipe processing, in particular to a device for oil pipe drilling. Background technique [0002] Oil extraction machine is a kind of machine equipment for oil extraction, commonly known as "kowtow machine", which makes oil out of the well by pressurizing. When the pumping unit is upstroke, the oil pipe elastically shrinks and moves upwards, driving the mechanical unblocking oil extractor to move upwards, hitting the sliding sleeve to generate vibration; at the same time, the forward check valve is closed, and the variable diameter piston assembly blocks the oil when the pumping unit goes down. During the stroke, the tubing elastically elongates and moves downward, driving the mechanical unblocking extractor to move downward, hitting the sliding sleeve to generate vibration; at the same time, the reverse check valve is partially closed, and the variable-diameter piston assembly still blocks the annular ...
