Oil and gas pipeline stress and displacement on-line detection device

The utility model provides an oil and gas pipeline stress and displacement on-line detection device, which belongs to the technical field of oil and gas pipeline detection devices, and comprises a base, and the upper end of the base is fixedly connected with a pipeline and a circuit box body; the detection mechanism comprises a universal shaft, a first baffle plate, a circuit box body, a second baffle plate, a measuring part, a data transmission part and a plurality of groups of transmission parts; according to the device, displacement, caused by sliding force brought by a mountain, of the pipeline in all directions can be converted into the horizontal linear direction through the universal shaft in a unified mode, then the displacement amount and the stress magnitude of the pipeline can be accurately measured through the displacement sensor and the stress sensor, and the displacement amount and the stress magnitude are uploaded in real time through the optical cable for online detection.
