Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and in particular to a pipeline thickness detection device. Background Art

[0002] A pipeline refers to a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Before the pipeline is installed and used, a thickness detection device is needed to detect the thickness of the pipeline wall to ensure the quality of the pipeline.

[0003] A Chinese utility model patent with publication number CN220136309U discloses a thickness detection device for PVC pipes. In view of the problem that the existing general thickness detection can only perform simple measurement of the thickness of the pipe but cannot measure the uniformity of the pipe thickness, the following scheme is proposed, which includes a vertical plate fixedly mounted on the top of the base, a clamping assembly is installed on the right side of the vertical plate, and a rotating cover is rotatably connected to the right side of the vertical plate, a moving rod is slidably connected in the rotating cover, the right end of the moving rod extends to the right side of the rotating cover and is rotatably connected to a handle, an adjustment assembly is installed on the top of the handle, and a first measuring arm and a second measuring arm are respectively installed on the adjustment assembly. After the pipe is positioned and clamped, the first measuring arm and the second measuring arm can be made to perform circular motion by rotating the handle, so the utility model has good practicality.

[0004] The device is provided with a base, a vertical plate is fixedly installed on the top of the base, a rotating cover is rotatably connected to the right side of the vertical plate, and a moving rod is slidably connected inside the rotating cover. When the thickness of the pipeline is detected, the staff places the pipeline to be detected on the bottom clamping plate, and then clamps it through the upper clamping plate, and then adjusts the first measuring arm and the second measuring arm by rotating the handle on the moving rod to realize the detection of the pipe thickness. However, the rotating cover is fixed in the vertical direction. When the pipeline specification is small, the first measuring arm and the second measuring arm on the right side of the rotating cover cannot effectively detect the pipeline, and the scope of application is small.

The output shaft of the motor 7 is connected and fixed to one end of the screw 701. The screw 701 is rotatably connected to the placement frame 3. Threaded sections in opposite directions are provided at both ends of the screw 701. There are two groups of clamping plates 8, which are respectively threadedly sleeved on one side of the screw 701. When the staff starts the motor 7, the motor 7 drives the screw 701 to rotate. The screw 701 drives the two groups of clamping plates 8 to approach synchronously through the threaded sections in opposite directions on both sides, thereby achieving effective clamping of the pipeline and convenient operation.

[0027] In at least one embodiment, a rubber pad is provided on one side of the clamping plate 8 close to the middle of the clamping slot, and the rubber pad is provided on the clamping plate 8 to avoid damage to the pipeline during clamping.

[0028] In at least one embodiment, the bottom of the slot is arc-shaped to prevent the pipe from rolling when the pipe is placed.

A limit groove matched with the limit block 503 is provided on the pressure block 501. By setting the arc-shaped pressure plate 502, effective contact with the inner wall of the pipeline is achieved to ensure the detection accuracy, and the limit block 503 can limit the pressure plate 502 to ensure the stability of the pressure plate 502.

[0030] In at least one embodiment, a snap ring 504 is fixedly provided on the connecting rod 5, the snap ring 504 abuts against the top of the fixed block 4, and the scale line is located below the snap ring 504.
