Corrugated pipe displacement laser sensor detection device and method

Abstract

The invention discloses a corrugated pipe displacement laser sensor detection device and method. The device comprises a measuring platform, a rotating platform, a laser range finder, a pressing deviceand a guide driving device, wherein the rotating platform is arranged on the measuring platform, the rotating platform rotates under driving of a rotating driving motor, a corrugated pipe is arrangedon the rotating platform, the corrugated pipe is extruded under an action of the pressing device, the laser range finder is arranged at a side of the corrugated pipe and moves under the driving of the guide driving device, and the laser range finder and the guide driving device are respectively connected to an industrial personal computer. By the adoption of the corrugated pipe displacement lasersensor detection device and method, a detection process of axial and radial displacement of a corrugated pipe expansion joint is realized; compared with the device constructed by the detection method, the device has low cost and simple algorithm; the displacement of the expansion joint in two directions can be detected, the axial and radial displacement detection of the corrugated pipe expansionjoint with different angles can be quickly realized, and the detection method is more comprehensive.

Description

technical field [0001] The invention relates to a detection device and method of a bellows displacement laser sensor, in particular to a detection device and method suitable for the non-working condition of a laboratory bellows. Background technique [0002] With the rapid development of the national economy, pipelines are widely used in the fields of heating, heat supply, oil and gas transportation, and various industrial supplies manufacturing. However, due to changes in pipeline temperature and pressure during transportation, pipelines will expand with heat and contract with cold, and move and deform. If these changes cannot be compensated, serious pipeline transportation safety accidents will occur. Therefore, as an elastic element that can absorb the expansion and contraction caused by thermal expansion and contraction, the expansion joint can improve the reliability and safety of pipeline transportation, and thus has been widely used. [0003] There are not many domes...
