Spot thickness measurement device of petroleum pipeline

Abstract

The present invention discloses a spot thickness measurement device of a petroleum pipeline. The structure of the device comprises an arch centring, fixed devices, beaters, measurement devices and strike devices. The fixed devices are respectively fixedly connected with two ends of the arch centring with an arch structure, there are a pair of fixed devices, a pair of beaters, a pair of measurementdevices and a pair of strike devices, the beaters are locked at the bottom portions of the fixed devices, the bottom portions of the beaters are movably connected with one ends, far away from the strike devices, of the measurement devices, one ends, far away from the beaters, of the measurement devices are in contact with the upper end faces of the strike devices, each fixed device is formed by one circular shaft, one friction shaft, one pressure bearing device, one inverted column and one pole, and each circular shaft is mutually engaged with each friction shaft. The spot thickness measurement device of a petroleum pipeline can allow dust at the inner wall to fall off while measurement is performed, and therefore reasonable cleaning of redundant dust thickness in the pipeline wall can beachieved.

Description

technical field [0001] The invention relates to a fixed-point thickness measuring device for an oil pipeline, which belongs to the field of oil pipeline thickness measurement. Background technique [0002] The oil pipeline is composed of oil pipes and their accessories. According to the needs of the process, it is equipped with corresponding oil pump units. It is designed and installed as a complete pipeline system to complete the tasks of oil loading, unloading and transportation. When the pipeline is in use, it needs Periodic testing of the wall thickness of the pipes is carried out. [0003] When testing pipelines in the prior art, since the material inside the pipeline is easy to adhere to the inner wall of the pipeline to form dirt during the transmission process, the detection accuracy of the thickness measuring device during the working process is easily affected. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the pr...
