It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] See also Figure 1-4The embodiment provided by the present invention is a suspension pipe welding device, comprising a workbench base 1, a lower card seat 2 is fixedly provided on the top of the base 1, an upper card seat 3 is rotatably connected to the top of the lower card seat 2, the base 1 and the lower card seat 2 are fixedly connected to form an integral structure, the internal dimensions of the lower card seat 2 and the upper card seat 3 are the same, which is convenient for the installation and limitation of the suspension pipe, a connecting ear 10 is fixed on the side wall of the lower card seat 2, a lower card seat 2 5 is fixed on the surface of the base 1 close to the lower card seat 2, and the lower card seat 2 5 is fixed on the side wall of the base 1. The top is rotatably connected to the upper card seat 2 6, the outer dimensions of the lower card seat 2 5 and the upper card seat 2 6 are respectively the same as the outer dimensions of the lower card seat 1 2 and the upper card seat 1 3, and the height of the lower card seat 2 5 is the same as the height of the lower card seat 1 2. The surface of the base 1 close to the movable seat 4 is provided with a groove 8 for the movable seat 4 to be clamped. The surface of the movable seat 4 is flush with the surface of the base 1. The inner bottom of the groove 8 is provided with a hole groove 2 14. The bottom end of the movable seat 4 is fixed with a limiting rod 15, which is rotatably connected to the hole groove through a bearing. The interior of the second 14 is provided with a limit pin 7, thereby improving the stability of the rotation. The surface of the movable seat 4 is plugged with a limit pin 7. The surface of the movable seat 4 is provided with a hole groove 3 16. The groove 8 is provided with a plurality of hole grooves 9 at equal intervals around the inner bottom of the hole groove 2 14. The internal dimensions of the hole groove 19 and the hole groove 3 16 are the same. The limit pin 7 is sequentially inserted into the interior of the hole groove 3 16 and the hole groove 1 9, thereby improving the stability and accuracy of the rotation positioning of the movable seat 4. The lower card seat 2 5, the movable seat 4 and the limit rod 15 are all fixed with cast iron. The connection forms an integrated structure. When the operator pushes the lower clamping seat 2 5, the movable seat 4 can be driven to rotate around the limit rod 15, thereby changing the angle of the lower clamping seat 2 5 and the lower clamping seat 1 2, so as to facilitate the adaptation and welding of suspension pipes with different bending angles. The operator clamps the suspension pipes at both ends inside the lower clamping seat 1 2 and the lower clamping seat 2 5 in turn, and then rotates the upper clamping seat 1 3 and the upper clamping seat 2 6 in turn to limit them, so that the ends of the suspension pipes at both ends are docked in turn for easy welding, thereby improving the efficiency of the installation, positioning and welding of the suspension pipes.

[0021] The external dimensions of the movable seat 4 are matched with the internal dimensions of the groove 8, which improves the rotation stability of the movable seat 4. A connecting ear 2 11 is fixedly provided on the side wall of the upper clamping seat 3 near the connecting ear 10. The surfaces of the connecting ear 10 and the connecting ear 2 11 are provided with threaded holes for bolt connection, which improves the stability of the connection between the lower clamping seat 2 and the upper clamping seat 3. A connecting ear 3 12 is fixed on the side wall of the lower clamping seat 2 5, and a connecting ear 4 13 is fixed on the side wall of the upper clamping seat 2 6 near the connecting ear 3 12. The connecting ear 3 12 and the connecting ear 4 13 can be connected by bolts, which improves the stability of the connection between the lower clamping seat 2 5 and the upper clamping seat 2 6.

[0022] Working principle: When using this suspension pipe welding device, the operator first clamps a section of the suspension pipe into the interior of the lower clamping seat 1 2, then rotates the upper clamping seat 1 3 to wrap the suspension pipe, and connects the connecting ear 1 10 and the connecting ear 2 11 by bolts, thereby improving the stability of the support of one section of the suspension pipe. The operator then clamps another section of the suspension pipe to be welded into the interior of the lower clamping seat 2 5, rotates the upper clamping seat 2 6, and connects the connecting ear 3 12 and the connecting ear 4 13 by bolts, thereby improving the stability of the support positioning of the other section of the suspension pipe. Thereby, the ends of the two sections of the suspension pipe are butted together, thereby facilitating the welding of the suspension pipe. When it is necessary to weld suspension pipes with different bending angles, when the operator rotates the movable seat 4, the limit rod 15 can be driven to rotate inside the hole groove 2 14, and then the limit pin rod 7 is inserted into the hole groove 3 16 and the corresponding position of the hole groove 1 9 in turn, thereby limiting the rotation of the movable seat 4, thereby changing the angle of the lower clamping seat 2 5 and the lower clamping seat 1 2, thereby facilitating the adaptation and welding of suspension pipes with different bending angles, thereby improving the efficiency of the suspension pipe positioning welding.
