In this embodiment, the mounting shaft 7 serves to facilitate the rotation of the mounting frame 8, and the slide bar 9 serves to limit the position.

[0032] Reference Figure 3 , Figure 4 and Figure 5The connecting mechanism 13 includes an installation box 14, a collecting cylinder 15 is arranged inside the installation box 14, a through groove 16 is opened inside the collecting cylinder 15, a fixing belt 17 is arranged inside the through groove 16, a fixing groove 18 is opened on the outside of the collecting cylinder 15, a fixing rod 19 is arranged inside the fixing groove 18, a connecting plate 20 is arranged on the outside of the fixing rod 19, a spherical spring lock 21 is arranged on the outside of the connecting plate 20, a limiting plate 22 is arranged on the outside of the installation box 14, a ball groove 23 is opened inside the limiting plate 22, and a turntable 24 is arranged at one end of the collecting cylinder 15.

In this embodiment, the connecting plate 20 plays a positioning role, the spherical spring lock 21 and the ball groove 23 prevent the fixing rod 19 from falling off, and the positioning groove 18 plays the role of installing the positioning rod 19.

[0034] The implementation principle of this embodiment is:

[0035] First, use a lifting device to connect to the fixing ring on the top of the installation box 14, and then use the turntable 24 to drive the collection barrel 15 to rotate. While the collection barrel 15 rotates, the fixing belt 17 will be collected on the outside of the collection barrel 15. When the fixing belt 17 is adjusted to an appropriate length, the fixing rod 19 passes through the installation box 14 and is inserted into the inside of the fixing groove 18, which can prevent the collection barrel 15 from rotating during operation. At the same time, the spherical spring lock 21 will be snapped into the inside of the ball groove 23, which can effectively prevent the fixing rod 19 from falling off. The fixing belt 17 is wrapped around the outside of the collection barrel 15, and concrete pipes of different specifications are adapted according to the length of the collection fixing belt 17. Then, the concrete pipe is placed horizontally, and the rubber sheet 10 is placed on the outside and inside of the concrete pipe, and the crane starts working. The installation box 14 is pulled upward, and the installation box 14 begins to pull the fixing belt 17. Under the action of gravity, the inner angle of the first cross bar 3 and the second cross bar 4 gradually becomes smaller, driving the first support rod 5 and the second support rod 6 to do cross movement. With the continuous movement of the first support rod 5 and the second support rod 6, the rubber sheet 10 gradually fits the concrete pipe. Since the concrete pipe is cylindrical, its surface is not in the same parallel plane. The mounting frame 8 rotates slightly on the outside of the mounting shaft 7, the sliding rod 9 slides inside the mounting frame 8, and the support spring 11 is continuously compressed. Due to the different positions of the rubber sheet 10, the degree of compression of the support spring 11 also varies, so that the rubber sheet 10 fits more closely to the concrete pipe, which can avoid damage to the concrete pipe to the greatest extent.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] By adding the connecting frame 1, the first cross bar 3 and the second cross bar 4 are pulled, and the first cross bar 3 and the second cross bar 4 are used in combination to drive the first support rod 5 and the second support rod 6 to cross-move. The first support rod 5 and the second support rod 6 are used in combination to drive the mounting frame 8 to move. The mounting shaft 7 and the mounting frame 8 are used in combination to adjust the angle. The sliding rod 9, the supporting spring 11 and the rubber plate 10 are used in combination to fix the concrete pipe. By using the above structure to replace the wire rope, the corners of the concrete pipe can be effectively protected, thereby avoiding water leakage. By adding the installation box 14, it is convenient to rotate the collecting cylinder 15. By cooperating with the collecting cylinder 15 and the through groove 16, the length of the fixing belt 17 is controlled. By cooperating with the fixing rod 19 and the fixing groove 18, the collecting cylinder 15 is prevented from rotating. By adding the turntable 24, it is convenient to rotate the collecting cylinder 15. By cooperating with the spherical spring lock 21 and the ball groove 23, the fixing rod 19 is prevented from falling off. By using the above structure, the length of the fixing belt 17 can be adjusted according to concrete pipes of different specifications, which effectively avoids the situation where the required height cannot be reached after the steel wire is completely recovered.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
