The moving mechanism is provided with three sets, which are equidistantly arranged front and back. The moving mechanism includes a telescopic control mechanism, a telescopic rod, a connecting rod, a moving wheel and a central axis. The moving wheel is attached to the outer wall of the upper half of the oil and gas pipeline, and the control mechanism is connected to the lower middle side of the frame.

[0007] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an oil and gas pipeline operation monitoring device, including a main body, flanges are symmetrically fixedly installed at both ends of the main body, oil and gas pipelines are fixedly installed on the two flanges, the main body is provided with a plugging mechanism through a servo motor, the servo motor is fixedly installed at the bottom of the main body, the plugging machine includes a fixed box, the fixed box is fixedly installed inside the main body, the two sides of the fixed box are fitted and fixed to the two sides inside the main body, gas sensors are provided on both sides of the top of the main body through movable rods, and oil and gas pressure sensors and flow sensors are respectively fixedly installed on both sides of the bottom of the main body, and the oil and gas pressure sensors and flow sensors are respectively arranged on both sides of the servo motor.

[0008] Furthermore, one end of the movable rod is movably mounted on both sides of the top of the main body through a torsion spring shaft, and the gas sensor is fixedly mounted on both sides of the bottom of the movable rod.

[0009] Furthermore, the gas sensors are arranged on both sides of the top of the flange.

[0011] Furthermore, two adjustment plates are slidably mounted on both ends of the fixing rod through sliding holes, and the two adjustment plates are symmetrically limited and slidably mounted inside the inner groove.

[0012] Furthermore, a bidirectional screw is installed inside the main body for vertical rotation, and the bottom end of the bidirectional screw is fixedly connected to the output shaft of the servo motor.

[0013] Furthermore, the bidirectional screw rod penetrates and is rotatably installed inside the fixing box, and the adjustment plate is screwed and installed at both ends of the bidirectional screw rod through screw holes.

[0014] Furthermore, through holes are provided at the top and bottom of one side of the fixing box, and a sealing rubber plug is fixedly provided at a position corresponding to the through hole on one side of the other end of the adjusting plate.
