Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] like Figure 1-3 As shown, a pipe collecting and releasing trailer is provided with a trailer frame 1, a supporting device 2, and a rotating device 3. The supporting device 2 is used for lifting and supporting a reel 4, and the rotating device 3 drives the reel 4 to rotate. The supporting device 2 includes a supporting lifting mechanism 21 and a swing arm 22 arranged on both sides of the trailer frame 1. The two ends of the supporting lifting mechanism 21 are respectively movably connected to the trailer frame 1 and the swing arm 22. The two swing arms 22 are fixedly mounted on a transverse rotating shaft 23, and the transverse rotating shaft 23 is rotatably mounted on the trailer frame 1.

[0033] Specifically, the support and lifting mechanism 21 is a hydraulic lifting cylinder, and the support and lifting mechanism 21 is installed on both sides of the trailer frame 1. The support and lifting mechanism 21 can drive the reel 4 to rise or fall, and there is no need to use lifting equipment or hoisting equipment to place the reel 4 on the trailer frame 1, which reduces the work intensity of the operators and reduces the complexity and cost of operation; the support and lifting mechanism 21 is respectively connected to the swing arms 22 on both sides. Since the swing arms 22 on both sides are connected through the transverse rotating shaft 23, the transverse rotating shaft 23 can rotate on the trailer frame 1, so that the support and lifting mechanism 21 can move synchronously during the lifting process to maintain balance, avoid the problem of the reel 4 tilting to one side during the lifting process, and improve the safety performance of the equipment.

[0034] like Figure 3 , 5 As shown in FIG. 6 , a core shaft 41 is movably provided on the reel 4 , ball heads 42 are provided at both ends of the core shaft 41 , and pin holes are provided on the ball heads 42 .

[0035] Specifically, one end of the core shaft 41 is passed through the center hole of the reel 4, the two ends of the ball head 42 exceed the reel 4, and the pin is inserted into the pin hole of the ball head (not shown in the figure), and the core shaft 41 is installed on the swing arm 22.

The rotation driver 31 can accurately control the rotation of the core shaft 41 through the transmission system composed of the differential 33, the active transmission wheel 34 and the driven transmission wheel 35. By setting the differential 33, the rotation speed of the reel 4 can be flexibly adjusted according to different working conditions and requirements, thereby improving the reliability and stability of the system.

[0052] The present application discloses a pipe retracting and releasing trailer. By setting a support lifting mechanism 21, the reel 4 can be driven to rise or fall. There is no need to use lifting equipment or hoisting equipment to place the reel 4 on the trailer frame 1, which reduces the work intensity of the operators and reduces the complexity and cost of operation. The support lifting mechanism 21 is respectively connected to the swing arms 22 on both sides. Since the swing arms 22 on both sides are connected by a transverse rotating shaft 23, the transverse rotating shaft 23 can rotate on the trailer frame 1, so that the support lifting mechanism 21 can move synchronously and maintain balance during the lifting process, avoiding the problem of the reel 4 tilting to one side during the lifting process, and improving the safety performance of the equipment. By setting a differential 33, the rotation speed of the reel 4 can be flexibly adjusted according to different working conditions and requirements, thereby improving the reliability and stability of the system. By setting a movable pin 36 and a reel pin hole 38, the quick connection and disconnection between the shaft dial 32 and the reel 4 are achieved, and the stability and reliability of the connection are ensured by tightening screws 37.
