Description

Technical Field

[0001] The invention relates to the technical field of pipeline detection, and in particular to a nondestructive detection instrument for petroleum equipment and pipeline wear. Background Art

[0002] In-pipeline inspection refers to the use of pipeline media to drive the detector to run in the pipeline, real-time detection and recording of pipeline deformation, corrosion and other damage conditions, and accurate positioning operations. Most oil and gas pipelines are laid underground. Through in-pipeline inspection, various defects and damages can be discovered in advance, and the degree of danger of each pipe section can be understood. Accidents can be prevented and effectively reduced, and pipeline maintenance funds can be saved. It is an important measure to ensure pipeline safety.

[0003] When the existing pipeline detector is in use, due to the long-term use of the pipeline, oil residues and impurities in the oil will accumulate on the inner wall, affecting the movement of the detector and adding unnecessary trouble to the detection. Summary of the invention

[0004] The invention provides a nondestructive detector for oil equipment and pipeline wear, which solves the technical problem that the pipeline detector is blocked by oil residues and impurities when moving.

[0005] In order to solve the above technical problems, the present invention provides a nondestructive testing instrument for petroleum equipment and pipeline wear, including a body, a camera and a lighting lamp are arranged at the front end of the body, a support plate is fixed to the side of the body, a rotating wheel is rotatably connected to the surface of the support plate, the other end of the rotating wheel relative to the support plate is transmission-connected to a drive motor, a track is arranged on the surface of the rotating wheel, a positioning tube is fixed to one end of the support plate, a rotating shaft is rotatably connected to the inside of the positioning tube, a control motor is transmission-connected to the upper end of the rotating shaft, a transmission tube is clamped on the surface of the rotating shaft, and a rotating plate is fixed to the surface of the transmission tube.

[0006] Preferably, the transmission tube is provided with rotating teeth inside, and the surface of the rotating shaft is provided with latching teeth, and the latching teeth are engaged with the rotating teeth.

[0007] Preferably, the control motor is fixed on the surface of the positioning tube, and the rotating shaft is rotatably connected to the positioning tube.

[0008] Preferably, a wireless device is disposed inside the body and is connected to an external controller.

[0009] Preferably, a fixing plate is fixed on the surface of the supporting device, a supporting shell is arranged in the middle of the track, a positioning shaft is fixed inside the supporting shell, and a rotating column is rotatably connected to the surface of the positioning shaft.

[0010] Preferably, a groove is provided on the surface of the supporting shell and a ball is provided inside the groove.

[0011] Preferably, the vertical distance between the top ends of the rotating columns at both ends of the support shell is equal to the outer diameter of the rotating wheel.

[0012] Compared with the related art, the nondestructive testing instrument for petroleum equipment and pipeline wear provided by the present invention has the following beneficial effects:

[0013] 1. The present invention controls the motor to drive the rotating plate to rotate. The rotating plate rotating in the opposite direction can push away the viscous oil residues, reduce the contamination of the track, thereby reducing the resistance caused by the oil residues adhering to the track surface, and extending the moving distance of the detector inside the pipeline. At the same time, the rotating plate can push the detector to adjust its direction by rotating in the opposite direction, so as to maintain normal progress.

[0014] 2. The present invention presses the crawler track downwards through the supporting device, thereby increasing the contact area between the crawler track and the ground, thereby reducing the slippage of the crawler track and ensuring that the detector moves forward stably.
