In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to the attached drawings 1-4, the large-diameter composite pipe on-site unwinding device comprises an unwinding disc 1 wound with a composite pipe and a support 2 used for rotatably supporting the unwinding disc 1. The unwinding disc 1 fully wound with the composite tubes is supported by the support 2 to rotate, and unwinding of the composite tubes wound on the unwinding disc 1 is completed. The composite pipe hanging device aims at solving the problem that the composite pipe body is pulled due to the gravity action of the composite pipe body because the composite pipe is high in hanging height. And a lifting mechanism for the reel releasing disk 1 is arranged on the support 2. Through the adjustment of the lifting mechanism, the part of the composite pipe which is unreeling and is separated from the unreeling disc 1 is always kept at a lower height with the ground, and the damage to the body of the composite pipe in the unreeling process is avoided. Meanwhile, in order to avoid the problem that the unwinding speed is unstable and the composite tube is separated from the unwinding disc 1 and the front end and the rear end of the composite tube are impacted or pulled, a speed regulating mechanism for controlling the unwinding speed of the unwinding disc 1 is arranged on the support 2. The unwinding disc 1 is always kept to have stable and uniform unwinding speed through the speed regulating mechanism, so that the problems of impact and dragging of the composite pipe body caused by instability of the unwinding speed are avoided.

Specifically, the lifting mechanism comprises a sleeve 3 which is rotatably sleeved on a rotating shaft (shown by a reference number 15 in the figure) of the unwinding disc 1, and a driving device which is connected with the sleeve 3 and lifts the sleeve 3 is arranged on the support 2. Preferably, the driving device comprises a motor 12 and a lead screw 13 which are arranged on the bracket 2, and one side of the sleeve 3 is sleeved on the lead screw 13.
