[0020] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:

[0021] like Figures 1 to 4 As shown, a prefabrication site pipeline transportation device described in the utility model comprises a support part 1, which can be set to a rectangular parallelepiped or cylindrical shape according to actual needs. The support part 1 is provided with rollers 2 through a triangular mounting frame, wherein two rollers 2 are provided, respectively located on both sides of the middle of the support part 1; two height-adjustable support brackets 3 are symmetrically provided on the support part 1, and the support bracket 3 is a structure with an open top and an arc-shaped bottom, which is used to support and lift the pipeline to be transported, wherein an auxiliary plate 4 is provided on one side of the support bracket 3 to be inclined outward, and the auxiliary plate 4 is used to provide assistance for the placement of the pipeline into the support bracket 3, so that the pipeline to be transported can be pushed along the inclined auxiliary plate 4 to smoothly enter the support bracket 3. In this embodiment, the support bracket 3 is located within the width range limited by the two rollers 2, so that the pipeline to be transported is located below the support part 1, which can ensure the balance of the entire device; in addition, the distance between each support bracket 3 and the middle of the support part 1 is less than the distance between it and the nearest end of the support part 1, so that the arrangement can meet the transportation of pipelines of various lengths as much as possible, and expand the scope of application of the utility model.

[0022] Furthermore, a cavity is provided in the support portion 1, in which a rotating rod 5 is rotatably provided, a winding wheel 6 is provided on the rotating rod 5, and a wire rope 7 is provided on the winding wheel 6, and the wire rope 7 is connected to the support bracket 3; the wire rope 7 on the winding wheel 6 is wound or released by controlling the rotating rod 5 to rotate forward and reversely to meet the height adjustment of the support bracket 3; the rotating rod 5 can be adjusted manually or driven by a motor 8; when adjusted manually, a rocker can be installed on the rotating rod 5, and a self-locking mechanism can be installed on the rocker to ensure the stability of the rotating rod 5 during use; in this embodiment, in order to further improve efficiency and reduce labor intensity, a motor 8 with a self-locking function is provided at one end of the support portion 1, and the motor 8 is connected to the rotating rod 5 by a coupling, and a battery 9 is connected to one side of the motor 8, and the battery 9 is used to provide power to the motor 8, and the battery 9 can be charged to meet the use requirements.

[0023] Among them, a protective cover 10 is provided at one end of the support part 1, and the motor 8 and the battery 9 are arranged in the protective cover 10. A heat dissipation mesh plate 11 is provided on the protective cover 10 to prevent the protective cover 10 from being completely sealed and affecting the normal operation of the motor 8 due to excessive temperature; in addition, a slot is also provided at the end of the protective cover 10 for the charging port on the battery 9 to extend out. In addition, in this embodiment, an operating part 12 is also provided at one end of the support part 1 away from the protective cover 10. The operating part 12 is preferably a cylinder smaller than the support part 1, and handles are vertically provided at both ends to facilitate the movement of the entire conveying device.

[0024] Furthermore, a guide rod 13 is provided on one side of the support bracket 3, and a guide hole 14 for the guide rod 13 to pass through is penetrated on the support part 1; the wire rope 7 is connected to a fixing plate 15 provided on the guide rod 13; the provision of the guide rod 13 can ensure the stability of the support bracket 3 during the transportation process, and avoid the situation in which the pipeline becomes unstable and falls due to the shaking of the wire rope 7 during the transportation process. Among them, a limit block 16 is set at the top of the guide rod 13, and the size of the limit block 16 is larger than the size of the guide hole 14, so as to limit the guide rod 13 and prevent the guide rod 13 from falling off due to accidents; in addition, a push rod 17 is movably arranged at the bottom of the support bracket 3, and an arc-shaped support plate 18 is arranged at the top of the push rod 17, and a receiving groove matching the support plate 18 is arranged in the support bracket 3; wherein in the initial state, the bottom end of the push rod 17 is lower than the bottom end of the auxiliary plate 4, so that when the support bracket 3 is lowered in height, the bottom of the push rod 17 is first in contact with the ground; the setting of the push rod 17 can enable the push rod 17 to be in contact with the ground first when the pipeline is taken out after being placed in the support bracket 3, as the height of the support bracket 3 is lowered, the push rod 17 will be in contact with the ground first, and will lift the pipeline to facilitate the removal of the pipeline.

[0025] Furthermore, the guide rod 13 is movably connected to the support bracket 3, so as to facilitate the rotation adjustment of the direction of the support bracket 3 to meet the different placement positions of the pipeline to be transported. Specifically, the outer movable sleeve of the guide rod 13 is provided with a limit sleeve 19, and the limit sleeve 19 is provided with a limit hole 20. The guide rod 13 is provided with a limit column 21 located in the limit hole 20. The length of the limit hole 20 is greater than the vertical height of the limit column 21, so as to adjust the limit sleeve 19 to slide up and down; in the initial state, the limit column 21 is in contact with the top of the limit hole 20; the top fixed sleeve of the support bracket 3 is provided with a positioning sleeve 22, and the positioning sleeve 22 is provided with a toothed sleeve on the end surface opposite to the limiting sleeve 19. Teeth 23, in the initial state, the positioning sleeve 22 and the limiting sleeve 19 are engaged and positioned by the teeth 23 to ensure the stability of the position of the supporting bracket 3; when the supporting bracket 3 needs to be adjusted, the limiting sleeve 19 is pulled up, and the teeth 23 will be disengaged. After rotating the supporting bracket 3 180 degrees, the limiting sleeve 19 is lowered and the teeth 23 are re-engaged. Due to the limitation of the limiting column 21, the limiting sleeve 19 will not rotate, so the stability of the supporting bracket 3 can be guaranteed. The structure is simple, the operation is easy, and the practicability is strong.

[0026] When the utility model is used, when it is necessary to transport the pipeline, first start the motor 8 to control the rotation of the rotating rod 5, release the wire rope 7 to lower the support bracket 3, then push the pipeline along the auxiliary plate 4 into the support bracket 3, and finally control the motor 8 to reverse, so that the wire rope 7 is reeled in to lift the support bracket 3; the utility model has a simple structure and is easy to operate, and can quickly realize the flexible transportation of a single pipeline, with a wide range of applications and strong practicality.
