Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a pipe turning machine for corrosion protection of heating pipelines. Background Technology

[0002] Corrosion protection of heating pipelines is a crucial step in ensuring the long-term safe and efficient operation of the system, especially in underground direct burial or high-humidity, highly corrosive environments. It mainly includes surface treatment, anti-corrosion coating, joint and node treatment, and electrochemical protection. Among these, the application of anti-corrosion coating to heating pipelines is the core element ensuring their long-term safe and efficient operation.

[0003] In the application of anti-corrosion coatings to heating pipes, a support mechanism is needed to hold the pipe in place and allow it to rotate continuously while the anti-corrosion coating is applied to its surface. A patent application with application number 202223175942.2, entitled "A Pipe Surface Treatment Device," includes a base. Support seats 11 are fixed to both sides of the top of the base 1. Rollers 12 are mounted on both sides of the top of each support seat 11. Supports 13 are rotatably connected to both ends of each roller 12. The tail end of each support 13 is fixedly connected to the side wall of the support seat 11. A motor 14 is fixed to the outer wall of one of the supports 13. The drive shaft of the motor 14 passes through the support 13 and is fixedly connected to one end of the roller 12. During the support of the steel pipe, to ensure comprehensive rust removal, the motor 14 drives the roller 12 to rotate, thereby rotating the steel pipe and ensuring comprehensive rust removal.

[0004] However, in the above scheme, the rotation of the heating pipe will cause axial movement, which will affect the uniformity of the coating. Utility Model Content

The base is provided with positioning wheels for positioning the pipe ends.

[0007] Furthermore, a first movable frame that moves on the base is located between the two support wheels, and the positioning wheel is disposed on the first movable frame.

[0008] Furthermore, the first movable frame is connected to the base via a guide rail slider.

[0009] Furthermore, a vertical plate is provided at one end of the outer side of the base, and a threaded rod is provided on the vertical plate that passes through the vertical plate and is threadedly connected to the vertical plate. One end of the threaded rod is rotatably connected to the first movable frame.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0019] like Figure 1 As shown, a pipe rotating machine for corrosion protection of heating pipelines includes symmetrically arranged bases 1 and symmetrically arranged support wheels 2 on the bases 1 for supporting the pipe ends. The bases 1 are equipped with positioning wheels 3 for positioning the pipe ends. The bases 1 on both sides are placed symmetrically, and then the pipe is placed on the support wheels, with the pipe ends supported between the two support wheels on the corresponding bases. Then, one support wheel 2 rotates, thereby driving the pipe to rotate. After the pipe is placed, the positioning wheels 3 position the pipe ends to prevent axial movement during rotation and ensure uniform coating of the anti-corrosion material on the pipe surface.

[0020] like Figure 1 As shown, a first movable frame 4 is provided on the base 1 between the two support wheels 2, and the positioning wheel 3 is set on the first movable frame 4, with the rotation axis of the positioning wheel 3 in the vertical direction. After the bases 1 on both sides are placed, the two ends of the pipe are supported on the corresponding support wheels 2. By moving the first movable frame 4, the positioning wheel 3 is brought into contact with the end of the pipe, reducing the positional accuracy requirement of the base 1 and adapting to slight changes in the length of the pipe.

[0021] like Figure 1 As shown, the first movable frame 4 is connected to the base 1 via a guide rail slider.

[0022] like Figure 1 As shown, a vertical plate 5 is provided at one outer end of the base 1. A threaded rod 6 is provided on the vertical plate 5, passing through the vertical plate 5 and threadedly connected to it. A sleeve is provided on the vertical plate 5, and the sleeve has an internal thread. The threaded rod 6 passes through the sleeve and engages with the internal thread of the sleeve. One inner end of the threaded rod 6 is rotatably connected to the first movable frame 4. This rotatable connection can be achieved using a bearing, which is existing technology and will not be elaborated further here. When the threaded rod 6 rotates, the action of the threaded rod 6 and the internal thread of the sleeve pushes the first movable frame 4 to move on the base 1.

[0023] like Figure 2 As shown, a handle 7 is provided at one end of the outer side of the threaded rod 6, and the threaded rod 6 is rotated by the handle 7.

There are four elongated holes 9, and each second movable frame 8 corresponds to two elongated holes 9. The bottom of the second movable frame 8 is provided with a connecting plate, which is connected to the base by bolts. By loosening the bolts, the second movable frame 8 can be moved along the elongated holes 9.

[0026] like Figure 2 As shown, a motor 10 is provided on the second movable frame 8 on one side. A first gear 11 is provided on the output shaft of the motor 10. A second gear 12 that meshes with the first gear 11 is provided on the rotating shaft of the support wheel 2. When the output shaft of the motor 10 rotates, the corresponding support wheel 2 rotates under the action of the first gear 11 and the second gear 12.
