[0023] The pipeline transportation trolley provided by the technical solution is mainly composed of a first frame and a second frame that are detachably connected. A trolley handle 2 is arranged on the top of the first frame. The trolley handle 2 can be a steel pipe, one end of which is connected to the first frame and the other end is provided with an anti-slip cover 1 to prevent the hand from slipping. The bottom of the first frame and the bottom of the second frame are both provided with walking wheels 9. When in use, the first frame and the second frame can be flexibly selected for use according to the length of the pipeline. A pair of vertical limit rods 14 are movably arranged on the first frame and the second frame. When in use, the pipeline is clamped between each pair of limit rods 14 to prevent the pipeline from rolling at will. The moving direction of the limit rod 14 is perpendicular to the moving direction of the trolley, that is, the length direction of the pipeline is the same as the moving direction of the trolley. The long pipeline can cross the first frame and the second frame for stable support.

[0024] The method of using the pipeline transportation trolley provided by the technical solution is as follows: when using, place the pipeline between a pair of limit rods 14, and adjust the position of each limit rod 14 so that the distance between each pair of limit rods 14 is equal to the outer diameter of the pipeline to ensure that the pipeline cannot roll, and then hold the trolley handle 2 to push the first frame, while driving the second frame to move the pipeline.

[0025] The utility model includes at least the following beneficial effects: a pair of vertical limit rods 14 that move perpendicularly to the moving direction of the trolley are both provided on the first frame and the second frame, and the pipe clamp is arranged between each pair of limit rods 14. By moving each limit rod 14, the distance between the pairs of limit rods 14 can be flexibly adjusted, so as to adapt to clamping pipes of different diameters, limit the pipes, effectively prevent the pipes from rolling during transportation, and enable the trolley to smoothly transport pipes of different diameters; the first frame and the second frame are detachably connected, and the first frame can be flexibly selected to transport the pipe or the first frame and the second frame can be used together to transport the pipe according to the use requirements. For example, only the first frame can be used to transport short pipes, which reduces the volume of the trolley and makes the trolley more convenient and labor-saving to use.

When adjusting the position of the limit rod 14, the limit rod 14 is first moved along the first slideway, and the first connecting block at the bottom of the limit rod 14 is moved along the first support tube 16 at the same time. After moving to the specified position, the positioning rod is inserted into the second positioning hole and the corresponding first positioning hole 15; the positioning rod can be a screw, which is convenient for disassembly and assembly; the limit rod 14 is detachably connected to the first connecting block, which is convenient for replacing the limit rod 14.

During transportation, the tail end of the pipeline is located on the first support plate 12, and the first support plate 12 provides a certain support force for the pipeline, and the baffle 3 can prevent the pipeline from moving toward the worker.

[0029] In another technical solution, Figure 1 , Figure 3 As shown, in the pipeline transport trolley, the baffle plate 3 is provided with an adjustment block 4, the adjustment block 4 is provided with a vertical lifting rod 6 for lifting, a horizontal limit plate 13 is provided at the bottom of the lifting rod 6, and the pipeline is clamped between the limit plate 13 and the first support tube 16.

The rotation of the lifting rod 6 drives the lower connecting plate 19 to rotate and rise and fall, and the limit plate 13 only rises and falls with the lifting rod 6 under the limiting effect of the baffle 3; the lower connecting plate 19 prevents the lifting rod 6 from being separated from the upper connecting plate 17.
