The lifting drive device is arranged on the bottom surface of the frame mechanism, and its output end is connected to the lifting plate to drive the lifting plate and the components thereon to perform lifting movements as a whole, thereby adjusting the height of the frame mechanism according to the height of the pipeline.

[0040] The working principle includes: When in use, the mechanism can be placed next to obstacles such as pipelines. The position sensor senses or detects the height and width of the pipeline.

The rotation drive device rotates the support legs to a vertical state to prop up the frame mechanism, and then the lifting drive device is started to lift the frame mechanism to a height exceeding the pipeline; the telescopic drive device is started to drive the frame mechanism to extend. At this time, the support legs on the frame that are extended to the top of the pipeline are folded to avoid it until these support legs move to the other side of the pipeline and then rotated open; the translation drive device is started and drives multiple groups of support mechanisms close to the pipeline to move inward to clamp the pipeline. The outer support mechanisms can choose not to move or to perform adaptive translation according to the preset maximum spacing threshold between the support mechanisms until the entire device is covered on the pipeline or obstacle; Or when in use, the device is directly placed on the obstacle, the position sensor senses or detects the height and width of the pipeline, and the controller first starts the telescopic drive device to adjust the length of the frame mechanism according to the detection information, and then the lifting drive device and the rotation drive device are started, the support legs are opened and their heights are adjusted to support the frame mechanism, and then the translation drive device is started and drives the multiple groups of support mechanisms close to the pipeline to move inward to clamp the pipeline, and the outer support mechanisms can choose not to move or to perform adaptive translation according to the preset maximum spacing threshold between the support mechanisms until the entire device is covered on the pipeline or obstacle; When the position sensor detects that the automated sampler moves to the side of the device, the support mechanism on the side close to the sampler descends first, so that the frame mechanism forms a slope, which is convenient for the sampler to move onto the frame mechanism; when the sampler moves to the middle of the frame mechanism, the support mechanism that was originally descended rises, and the support mechanism on the other side descends, which is convenient for the sampler to come down.
