In each of the drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, the various parts in the drawings are not drawn to scale.

[0028] The present utility model provides a pipeline pay - out rack, referring to Figures 1 to 4 , the pipeline pay - out rack includes: a support frame 1 and a pipeline rack 2; wherein, the support frame 1 is used for supporting on the ground, and the pipeline rack 2 is rotatably connected to the top of the support frame 1 through a disc damping rotating shaft 3; the pipeline rack 2 includes a rotating shaft 21, a lower cross bar 22 and an upper cross bar 23, a plurality of the lower cross bars 22 are uniformly arranged along the circumference at the lower end of the rotating shaft 21, and two of the upper cross bars 23 are arranged along the same radial direction at the upper end of the rotating shaft 21; a pipeline tightening stop bar 24 is vertically arranged on each of the upper cross bars 23, and the position of the pipeline tightening stop bar 24 on the upper cross bar 23 is adjustable.

[0029] When the pipeline pay-off rack is in use, it can be supported on the ground through the support frame 1. The coiled pipeline is placed on the pipeline rack 2, and the pipeline is paid off by pulling one end of the pipeline to make the pipeline rack 2 rotate. Since the pipeline rack 2 is rotationally connected to the support frame 1 through the disc damping rotating shaft 3, there will be a damping force during the rotation of the pipeline rack 2, which will not make the rotation speed of the pipeline rack 2 too fast, avoiding the pipeline from getting messy due to the too fast rotation speed of the pipeline rack 2. At the same time, a pipeline tightening stop rod 24 is arranged on the pipeline rack 2, which can abut against the inner side of the coiled pipeline, well controlling the looseness of the pipeline, avoiding the pipeline from becoming more and more loose during laying, keeping the pipeline neat, and thus improving the construction efficiency of pipeline pay-off.

[0030] Specifically, the support frame 1 includes a support base 12 and three support legs 11. Among them, the support base 12 includes a connecting pipe 121, a connecting plate 122 and three support leg connecting seats 123.
