Description

Technical Field

[0001] The utility model relates to the technical field of transportation, in particular to PCCP pipeline transportation equipment. Background Art

[0002] PCCP pipe is a kind of pipeline material widely used in water conservancy, municipal engineering and other fields. When transporting PCCP pipes over short distances, special transfer devices are required to ensure their safe and efficient movement. Due to the special nature of its material and structure, PCCP pipes face many challenges during short-distance transportation. The length and weight of the pipes are large, requiring strong load-bearing capacity and stable transfer devices to support them. Currently, transfer devices are required for short-distance transportation of PCCP pipes.

[0003] Most of the transfer devices in the existing technology cannot limit the pipeline, which easily causes the pipeline to deviate and collide during transportation. Based on these problems, Chinese patent CN221114011U discloses a PCCP pipeline transfer device. By providing a fixed ring, a mounting block and a bolt body, this design solves the problem that a transfer device is needed for the current short-distance transportation of PCCP pipelines. However, most of the traditional transfer devices cannot limit the pipeline, which easily causes the pipeline to deviate and collide during transportation. The specific operation is that a fixed ring is provided on the outer surface of the pipeline body, and the bolt body installed inside the mounting blocks on both sides of the fixed ring can limit the pipeline body on the device body, thereby preventing it from deviating and then colliding during transportation. By providing a connecting plate, a threaded rod and a motor body, this design can make the device body retract the universal wheel into the inside of the moving chamber when not in transportation, thereby preventing it from shaking and improving its stability in the non-transportation state.

[0004] The inner diameter of the fixed ring in the transfer equipment is fixed, so it can only fix PCCP pipes of specified diameters, which not only affects the application scope of the transfer equipment, but also reduces the utilization efficiency of the transfer equipment. Utility Model Content
