Embodiment Construction

[0049] A shot blasting strengthening and cleaning device for the inner and outer walls of an oil drill pipe, including a support part, a driving power part and a pneumatic shot blasting part, wherein the support part mainly forms an inclined structure for supporting the oil drill pipe, so that the oil drill The two ends of the rod can be placed on the supporting rollers of the support part to form a support, and can rotate under the drive of the motor. In the support part, there is also a slope for collecting shot blasting and a protective cover for protecting the entire shot blasting space. The collected shot blasting blanking enters a pneumatic conveying bin, which is a device for conveying shot blasting. The shot blasting is transported to the corresponding pipeline through the pipeline. The pneumatic shot blasting part includes a first nozzle and a second nozzle. The first nozzle blasts the outer wall of the oil drill pipe, and the second nozzle cleans the inner wall. The ...

Abstract

The invention discloses a shot-blasting intensifying and cleaning device for inner and outer walls of a petroleum drilling rod. The device comprises a supporting part, a driving power part and a pneumatic shot-blasting part, wherein supporting legs are arranged at four corners of a platform; two mounting seats are fixedly arranged on the platform; the height of each mounting seat is larger than the height of the other mounting seat; the tops of one of the two mounting seats are inclined; a pair of supporting wheels which can support one drilling rod is arranged on the top of each mounting seat; the drilling rod is in an inclined state; one supporting wheel is connected to a belt pulley by virtue of a universal coupling; the belt pulley is driven by a first motor by virtue of belt drive; a rubber layer covers the surface of the supporting wheel serving as a driving wheel; and the first motor, a second motor and a third motor form a driving part. The inner wall of the drilling rod is cleaned and intensified, so that the wear resistance and strength of the inner wall are effectively improved, and the wear problem generated in the process of contacting the inner wall of the traditional drilling rod and sand is solved.

Description

technical field [0001] The proposal relates to the production process of oil drill pipes, specifically a device for strengthening and cleaning the inner and outer walls of oil drill pipes by shot blasting. Background technique [0002] Oil drill pipe is generally composed of two parts: pipe body and joint. The pipe body is a rolled seamless steel pipe. In order to strengthen the strength of the pipe body and the joint, the two ends are generally thickened. Usually, the pipe body and joints are processed separately and then friction welded. [0003] Friction welding: The finished joints after joint processing are end-processed, crimped (butt weld the original pipes that have been turned at the ends with the finished joints sent from the processing line), weld annealing, finishing, weld quenching, weld seam Tempering, self-inspection, flaw detection, finished product spraying, and finally the finished oil drill pipe. [0004] In this process, there is no shot blasting proces...
