Problems solved by technology
[0003] In the prior art, the method for detecting the thread of the oil pipe is mainly to detect the helium gas seal, wherein the helium gas seal detection can only detect the connection effect of the connection at the joint, but it cannot find the damage of the thread, which will cause There are hidden dangers to the safe operation of the oil pipe, and manual detection directly through the naked eye is low in detection efficiency and cannot meet the needs of large-scale installation and production. In order to solve the above problems, a fast and convenient oil pipe thread detection method is provided. The present invention provides The following technical solutions

The invention discloses an oil pipe thread detection device for high-pressure oil and gas well operation, which comprises a cross beam, an adjusting mounting beam is fixedly mounted on the cross beam,and a measuring arm is mounted on the adjusting mounting beam; during working, two mutually hinged mounting arms are adopted to detect a threaded structure of an oil pipe, specifically, the rotatingwheel on one mounting arm rotates along a groove between two insections, two adjacent hard sliding sheets are respectively propped against two adjacent insection bulges, and the oil pipe to be detected is driven to rotate through a motor, and meanwhile, the automatic clamping hand is driven to slowly move in the horizontal direction, when the difference value between the detection values of the two laser range finders is larger than a preset value, it is considered that the threads at the corresponding positions are damaged, the whole process is automatically completed, the detection speed ishigh, and the positions with thread defects can be found in time.
Description
technical field [0001] The invention belongs to the technical field of thread seal detection, and in particular relates to an oil pipe thread detection device used in high-pressure oil and gas well operations. Background technique [0002] The oil pipe works under high temperature and high pressure, and it is easy to cause leakage accidents due to the quality of the oil pipe. Therefore, the requirements for the tightness and firmness of the oil pipe connection are high. The point lies in the threaded connection structure of the oil pipe. In order to ensure the safety of the connection, it is necessary to inspect the thread structure of the oil pipe before installation to determine whether the thread structure surface of the oil pipe is damaged; [0003] In the prior art, the method for detecting the thread of the oil pipe is mainly to detect the helium gas seal, wherein the helium gas seal detection can only detect the connection effect of the connection at the joint, but it...
