[0014] Beneficial effects:

[0015] 1. The present invention can conveniently adjust the angle of the fixing mechanism through the setting of the rotating mechanism to ensure the smooth operation of the trolley. Combined with the setting of the fixing mechanism, it can improve the fixing effect of the pipeline and prevent the pipeline from falling off during transportation. Specifically, when the pipeline is placed in the space between the two fixed arc seats, the gravity of the pipeline itself acts on the adjusting component and moves it downward. The downward moving adjusting component will squeeze the two movable arc seats and make them slide along the slide of the fixed arc seat. The ends of the two movable arc seats that are away from each other slide out of the fixed arc seat to wrap the space above the pipeline, thereby increasing the clamping range.

[0016] 2. In the present invention, by setting the top of the fixed arc seat lower than the center of the fixed arc seat, it can ensure that the opening of the space is always larger than the outer diameter of the pipe, thereby facilitating the installation and placement of the pipe; combined with the setting that the top of the movable arc seat is higher than the center of the fixed arc seat when it slides out, it can ensure that after the pipe is installed and placed, the opening of the space is smaller than the outer diameter of the pipe, thereby preventing the pipe from falling off from the opening.

[0017] 3. In the present invention, by setting the counterweight block, the movable arc seat can quickly return to its position when it is not affected by the external force of the adjustment component, which is convenient for disassembling the pipeline. Specifically, when the pipeline is disassembled, as the pipeline is supported by manual or mechanical means, the force of the pipeline on the adjustment component gradually decreases, and the adjustment component will move up with the pipeline. The two movable arc seats gradually retract into the fixed arc seat under the action of the counterweight block until the pipeline is completely separated from the adjustment component. At this time, the two movable arc seats are completely retracted into the fixed arc seat, and the opening of the space is completely opened, thereby facilitating the removal of the pipeline.

[0018] 4. In the present invention, by setting the upper larger and lower smaller adjustment blocks, the movable arc seat can be moved by utilizing the change in the size of the adjustment blocks. By setting the first spring, the elastic force of the first spring can be utilized to achieve automatic resetting of the adjustment block. By setting the first telescopic rod, the linear movement of the first spring and the adjustment block can be ensured. By coordinating the grooves and the protrusions, the movable arc seat can be prevented from deflecting during the sliding process, thereby improving the smoothness of the sliding.

[0019] 5. In the present invention, by setting up two movable blocks and an adjusting screw, the relative distance between the two fixed arc seats can be conveniently adjusted, thereby meeting the fixed transportation of pipes with different diameters; by setting up a buffer assembly including a rubber block, a second spring and a second telescopic rod, the elastic force of the second spring can be used to achieve adaptive clamping of the pipe, further facilitating the fixed transportation of pipes with different diameters. In addition, the rubber block and the second spring can be used to buffer the pipe, reducing the risk of pipe damage during transportation.

[0020] 6、The step motor, the gear set is set up in the application, can conveniently realize the rotation adjustment of the support column and the base, in addition, can also be quantitative to the rotation angle, specific through the calculation of the gear number and the gear set parameter, the setting of the limiting assembly can realize the fixation of the angle after adjustment, avoid the free swing of the pipeline with the support column in the transportation process.

[0052] In the embodiment, the rotation adjustment of the support column 2 and the base 1 can be conveniently realized through the arrangement of the stepping motor 51 and the gear set 52, and in addition, the quantitative adjustment of the rotation angle can also be realized, which is realized through the parameter calculation of the gear number and the gear set 52, and the fixed adjustment of the adjusted angle can be realized through the arrangement of the limiting assembly 53, so that the pipeline can be prevented from freely swinging with the support column 2 in the transportation process.
