Abstract

The invention discloses a test bed, and belongs to the field of petroleum production. Comprising a test bed base, a test bed cross beam, a first pressure unit, a stress signal acquisition unit and a driving unit, the test bed base comprises a bottom plate, a cross beam fixing frame and two test piece fixing frames, one end of the cross beam fixing frame is fixedly connected with the bottom plate, the other end of the cross beam fixing frame is fixedly connected with the test bed cross beam, one end of each test piece fixing frame is fixedly connected with the bottom plate, and the other end of each test piece fixing frame is fixedly connected with one end of a test piece; the first pressure unit is located on the bottom plate and between the two test piece fixing frames, and the first pressure unit is configured to apply thrust to the two test piece fixing frames to enable the test piece fixing frames to be far away from the first pressure unit; the stress signal acquisition unit is in sliding connection with the test bed cross beam, the driving unit is connected with the stress signal acquisition unit, and the driving unit is used for driving the stress signal acquisition unit to slide on the test bed cross beam. The test mode of the test bench can be enriched.

Description

technical field [0001] The present application relates to the field of petroleum production, in particular to a test bench. Background technique [0002] During the operation of oil and gas pipelines, various stresses will occur. When there are local defects in the pipeline, stress concentration will occur. Various micro and macro stress concentrations can easily develop into hidden safety hazards that threaten the integrity of the pipeline, resulting in shortened pipeline service life and even safety accidents. Therefore, the stress detection of the pipeline has an early warning effect, and it is of great significance to prevent the occurrence of pipeline failure accidents. [0003] In the process of pipeline stress detection, it is necessary to simulate the real stress of the pipeline according to the actual working conditions, and at the same time, it is necessary to detect the stress distribution of the pipeline, so as to obtain effective data that meets the requirement...
