[0004] Existing metal pipe manhole processing equipment such as the above-mentioned one mostly uses two sets of semicircular rings with fixed curvatures to clamp the metal pipe. In the specific implementation process, although the semicircular rings with fixed curvatures can fix the metal pipe, they can often only match metal pipes of corresponding sizes, which increases the limitations of the fixing mechanism of the metal pipe manhole processing. Therefore, it is urgent to propose a corresponding fixing mechanism for metal pipe manhole processing to solve the above problems. Utility Model Content

After the connecting seat drives the bracket to move to the specified position, the positioning rod is rotated so that its open end abuts against the top of the slide bar, thereby realizing the positioning of the slide bar and the bracket through friction. The setting of the base frame and the roller not only ensures the smooth movement of the connecting seat, but also can provide auxiliary support for the connecting seat. The metal pipe is placed on the fixing frame and the bracket. The fixing frame and the bracket of the triangular structure can adapt to metal pipes of different diameters.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A fixing mechanism for processing a manhole for a metal pipe comprises a horizontal seat 1 and a connecting seat 8. The outer wall of the connecting seat 8 is fixedly connected to a slide bar 11. The outer wall of the slide bar 11 is slidably connected to the inner wall of the horizontal seat 1. A positioning assembly for positioning the slide bar 11 is provided on the top of the horizontal seat 1. A fixing frame 4 and a bracket 6 are fixedly connected to the tops of the horizontal seat 1 and the connecting seat 8, respectively. Both the fixing frame 4 and the bracket 6 are triangular structures, and a limiting assembly for limiting the position of the metal pipe is provided on the top of the fixing frame 4.

[0025] According to the overall length of the metal pipe, move the connecting seat 8. After the connecting seat 8 drives the bracket 6 to move to the specified position, rotate the positioning rod 12 so that its open end abuts the top of the slide 11, so that the positioning of the slide 11 and the bracket 6 is achieved through friction. The setting of the base frame 9 and the roller 10 not only ensures the smooth movement of the connecting seat 8, but also can provide auxiliary support for the connecting seat 8. Place the metal pipe on the fixing frame 4 and the bracket 6. The triangular structure of the fixing frame 4 and the bracket 6 can adapt to metal pipes of different diameters. Then rotate the fixing rod 13, and the fixing rod 13 is screwed together with the top frame 5 until the open end of the fixing rod 13 abuts the outer wall of the metal pipe, so as to realize the positioning of the metal pipe before the manhole is processed. In this way, pipes of different diameters can be fixed while supporting metal pipes of different lengths, thereby improving the applicability of the fixing mechanism used for metal pipe manhole processing.

[0026] Specifically, such as Figure 2 and Figure 4As shown, the inclined ends of the fixing frame 4 and the bracket 6 are both engaged and connected with multiple groups of balls 7, and the multiple groups of balls 7 are linearly distributed. The inclined ends of the fixing frame 4 and the bracket 6 are both engaged and connected with multiple groups of balls 7. On the basis of not affecting the stable placement of the metal pipe, the friction between the metal pipe and the fixing frame 4 and the bracket 6 is reduced, ensuring the convenience of horizontal pushing and pulling or axial rotation of the metal pipe, thereby improving the convenience of using the fixing mechanism for metal pipe manhole processing.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the outer wall of the horizontal seat 1 is fixedly connected to the mounting piece 2, and the inner wall of the mounting piece 2 is screwed and connected to the locking rod 3 to facilitate the fixation of the horizontal seat 1 and the external workbench. The bottom of the connecting seat 8 is fixedly connected to the base frame 9, and the bottom of the base frame 9 is integrated with a roller 10, which not only ensures the smooth movement of the connecting seat 8, but also can provide auxiliary support for the connecting seat 8. The positioning assembly includes a positioning rod 12, the outer wall of the positioning rod 12 is screwed and connected to the inner wall of the top of the horizontal seat 1, and the open end of the positioning rod 12 abuts against the top of the slide bar 11 , rotate the positioning rod 12 so that its open end abuts against the top of the slide 11, thereby realizing the positioning of the slide 11 and the bracket 6 by friction, and the limiting assembly includes a top frame 5, the top frame 5 has a U-shaped structure, the vertical end of the top frame 5 is fixedly connected to the top of the fixed frame 4, and the inner surface wall of the horizontal end of the top frame 5 is screwed with a fixing rod 13, rotate the fixing rod 13, and screw the fixing rod 13 with the top frame 5 until the open end of the fixing rod 13 abuts against the outer wall of the metal pipe, thereby realizing the positioning of the metal pipe before the manhole is processed.

[0028] Working principle: according to the overall length of the metal pipe, move the connecting seat 8, and after the connecting seat 8 drives the bracket 6 to move to the specified position, rotate the positioning rod 12 so that its open end abuts against the top of the slide 11, thereby realizing the positioning of the slide 11 and the bracket 6 through friction. The setting of the base frame 9 and the roller 10 not only ensures the smooth movement of the connecting seat 8, but also can provide auxiliary support for the connecting seat 8. Place the metal pipe on the fixing frame 4 and the bracket 6. The triangular structure of the fixing frame 4 and the bracket 6 can adapt to metal pipes of different diameters. Then rotate the fixing rod 13, and the fixing rod 13 is screwed together with the top frame 5 until the open end of the fixing rod 13 abuts against the metal pipe. It belongs to the outer wall of the pipe, so as to realize the positioning of the metal pipe before the manhole is processed. In this way, pipes of different diameters can be fixed while supporting metal pipes of different lengths, thereby improving the applicability of the fixing mechanism for metal pipe manhole processing. Multiple sets of balls 7 are engaged and connected at the inclined ends of the fixing frame 4 and the bracket 6. Without affecting the stable placement of the metal pipe, the friction between the metal pipe and the fixing frame 4 and the bracket 6 is reduced, ensuring the convenience of horizontal pushing and pulling or axial rotation of the metal pipe, thereby improving the convenience of using the fixing mechanism for metal pipe manhole processing.
