Description

technical field [0001] The invention relates to the technical field of drill pipe detection equipment, in particular to a straightness detection device of a geological exploration drill pipe. Background technique [0002] Drill pipe is a steel pipe with a thread at the end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and together with the drill bit raise, lower or rotate the bottom hole device. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, drill pipe can be used many times. Drill pipe is divided into three categories: kelly, drill pipe and weighted drill pipe. Drill pipe is an important part of exploration drilling rig. In order to ensure the normal use of drill pipe...

[0003] Chinese invention patent 2017100643349 relates to a straightness calibration mechanism for geological exploration drill pipes, including a frame plate. The upper surface of the frame plate is symmetrically equipped with a plurality of contact sensing devices, support devices and feeding devices, and the frame plate The front side is fixedly connected with a material guide plate, a material shifting device and a storage rack; the contact sensing devices are evenly distributed on the frame plate, and the supporting device and the discharging device are symmetrically separated on the upper surface of the frame plate in the length direction At both ends, the feeding device is located between the two supporting devices. The straightness calibration mechanism of the geological exploration drill pipe has low straightness detection degree and poor detection accuracy.

[0004] In the prior art, various parts of the drill pipe are detected manually using a measuring ruler. However, the efficiency of manual measurement and detection using the measuring ruler is low, and it is difficult to realize high-precision and rapid detection of multiple drill pipes. Therefore, a geological exploration method is invented. It is necessary to solve the above problems with the straightness detection device of the drill pipe

[0005] At the same time, when the straightness of the geological exploration drill pipe is inclined, it will hinder the rotation of the geological exploration drill pipe, which makes it difficult to rotate and cannot perform a complete and thorough detection of its inclination
