Embodiment 1

[0014] Such as figure 1 A fixed-point thickness measuring device for oil pipelines shown includes a detection bracket 1, and an ultrasonic thickness measurement device 2 is arranged on the detection bracket 1; a plurality of percussion cylinders 3 are arranged on the detection bracket 1, which respectively Extending along the radial direction of the oil pipeline, each knocking cylinder 3 is provided with a knocking end body 4 at the end.

[0015] As an improvement of the present invention, the detection bracket 1 adopts a ring structure extending circumferentially along the oil pipeline, and a plurality of support end bodies 5 are arranged on the inner wall of the detection bracket 1, which respectively extend along the radial direction of the detection bracket 1. Extending, each supporting end body 5 adopts an arc-shaped structure attached to the end surface of the oil pipeline relative to the end surface of the oil pipeline. Adopting the above-mentioned technical scheme, it...

Embodiment 2

[0019] As an improvement of the present invention, the two sides of the detection bracket 1 are respectively provided with support end frames, and each support end frame all includes an electric screw rod 6 fixed on the detection bracket, and the bottom end of the electric screw rod 6 The upper part is provided with a supporting base 7 extending above the horizontal direction. By adopting the above technical scheme, the detection bracket can be fixed on the ground through the setting of the support end frame, so that the position stability of the detection bracket together with the ultrasonic thickness measuring device and other devices can be further improved; at the same time, the support end frame The electric screw rod provided in it can make it adjust the height according to the position of the pipeline, so that the applicability of the oil pipeline fixed-point thickness measuring device in the present application can be improved.

[0020] The remaining features and advan...

Abstract

The invention discloses a fixed point thickness measurement device for a petroleum pipeline. The fixed point thickness measurement device for the petroleum pipeline comprises a detection support, and an ultrasonic thickness measurement device is arranged on the detection support. A plurality of knocking air cylinders are arranged on the detection support and extend in the radial direction of the petroleum pipeline correspondingly. The end of each knocking air cylinder is provided with a knocking end body. According to the fixed point thickness measurement device for the petroleum pipeline, by the adoption of the technical scheme, in the process that the ultrasonic thickness measurement device measures the thickness of the wall of the petroleum pipeline, the knocking air cylinders arranged on the detection support drive the knocking end bodies to knock the inner wall of the petroleum pipeline to a certain extent, then dirt adhering to the inner wall of the petroleum pipeline falls off due to knocking, then the inner wall of the pipeline is kept clean, the situation that the dirt affects transmission of ultrasonic waves along the pipe wall is avoided, and accordingly the detection precision of the fixed point thickness measurement device for the petroleum pipeline is improved.

Description

technical field [0001] The invention relates to the field of pipeline detection, in particular to a fixed-point thickness measuring device for oil pipelines. Background technique [0002] Pipelines are affected by many factors during use, and are prone to wear and tear and even leakage. In view of the above situation, in order to ensure the safety of the pipeline in the process of material transmission, it is necessary to conduct regular inspections on the wall thickness of the pipeline. The existing pipeline thickness measurement is realized by the ultrasonic thickness measurement device. However, when testing some special pipelines, such as oil pipelines, the material inside the pipeline is easy to adhere to the inner wall of the pipeline during the transmission process to form dirt. , so that the detection accuracy of the ultrasonic thickness measuring device is easily affected during the working process. Contents of the invention [0003] The technical problem to be ...
