Problems solved by technology

[0003] In the prior art, the data measurement of the inner diameter of the oil drill pipe joint is generally carried out manually through the mutual cooperation of calipers, vernier calipers and steel rulers. After the personnel measure multiple joints, it is prone to fatigue measurement errors, so the measurement efficiency is low

Abstract

The invention discloses a detection device and a method for an oil drill pipe joint, which relates to the field of petroleum machinery, realizes the rapid and accurate data measurement of the inner diameter of the oil drill pipe joint, and improves the measurement efficiency. The invention provides a detection device, comprising: a hollow inner diameter detection rod, which has an inner diameter detection section, and an inner diameter support rod is arranged on the inner diameter detection rod; At the end, the axial direction of the rotating shaft is perpendicular to the inner diameter detection rod. An elastic part is arranged between the inner diameter support rod and the inner diameter detection rod. The elastic part is used to make the inner diameter support rod rotate in the radial direction of the inner diameter detection rod. The end is provided with a winding part; one end of the inner diameter detection wire is fixedly connected to the other end of the inner diameter support rod, and the other end of the inner diameter detection wire bypasses the winding part and extends into the hollow area of ​​the inner diameter detection rod and extends beyond the inner diameter detection rod . The invention is mainly used for the detection of relevant parameters of oil drill pipe joints.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a detection device and method for petroleum drill pipe joints. Background technique [0002] Oil drill pipe is an important part in oil and gas exploration and exploitation. It is mainly used to transmit torque and transport drilling fluid. The drill pipe is connected end to end through drill pipe joints, and the joints are processed with internal and external threads. During the production process of the drill pipe joint or the installation process of the drill pipe joint, it is necessary to measure the inner diameter of the drill pipe joint to ensure the precision of the production and the fit of the installation. [0003] In the prior art, the data measurement of the inner diameter of the oil drill pipe joint is generally measured manually through the cooperation of calipers, vernier calipers and steel rulers. This inspection method requires high measurement skills for the m...
