[0002] Currently, containerized power plants, modular power plants, and trailer-mounted power plants are common power generation devices, widely used in various large-scale power supply sites, serving as mobile emergency power stations. Welding exhaust pipes within these power plants is a crucial step in ensuring the safety of the power unit. The sealing requirements for the exhaust pipes within the power plant are high. Most existing pipe welding support devices can only move the pipes up and down; subsequent adjustments require manual alignment of the welding positions, which is prone to errors during welding and cannot guarantee the sealing of the exhaust pipes. Summary of the Invention

[0003] To address the issue that existing pipe welding support devices can only lift and lower the pipe, requiring manual alignment of the welding position for subsequent adjustments and prone to errors during welding, this invention proposes a pipe welding support device. By rotating the rotating bracket, the end of the pipe is aligned with the welding position. Then, a moving plate changes the longitudinal position of the pipe end, and a bracket changes the lateral position of the pipe end, ensuring proper contact between the aligned pipe end and the welding position, thereby improving the sealing performance of the weld after the pipe welding is completed.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A support device for pipe welding includes a base, a retractable lifting frame on the base, a rotatable rotating bracket at the upper end of the lifting frame, a movable plate on the rotating bracket, the position of the movable plate relative to the rotating bracket being longitudinally adjustable, a bracket on the movable plate, the position of the bracket relative to the movable plate being laterally adjustable, and the pipe being fixed on the bracket.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6 As shown, this embodiment provides a support device for pipe welding, including a base 1, on which a retractable lifting frame 2 is provided. (Refer to...) Figure 3 and Figure 4 The lifting frame 2 includes a support rod 21, a lifting rod 22, a base plate 23, a screw 24, and a support plate 25. There are four support rods 21 and four lifting rods 22, which are arranged correspondingly. The lifting rod 11 is slidably mounted on the support rod 21. Specifically, the support rod 21 has a vertical first sliding groove 211. There are multiple first sliding grooves 211. A first pin 212 is provided in the first sliding groove 211. The end of the first pin 212 passes through the first sliding groove 211 and the lifting rod 22 corresponding to the support rod 21 in sequence. The base plate 23 is fixed to the lower end of the plurality of lifting rods 22. The upper end of the screw 24 passes through the base 1 and the base plate 23 in sequence. The screw 24 is rotatably connected to the base 1 and threadedly connected to the base plate 23. For details, refer to [reference needed]. Figure 4 The nut of the screw 24 and the positioning block fixed on the screw 24 are located on the upper and lower sides of the base 1 respectively, ensuring the stable rotation of the screw 24 on the base 1; the support plate 25 is fixed to the upper end of the multiple lifting rods 22.

[0022] Further, refer to Figure 5 and Figure 6 The upper end of the lifting frame 2 is provided with a rotatable rotating bracket 3. Specifically, the bottom wall of the rotating bracket 3 is in contact with the upper end surface of the support plate 25. A positioning hole 31 is opened in the center of the bottom wall of the rotating bracket 3. A positioning rod 32 passes through the positioning hole 31. The lower end of the positioning rod 31 passes through the support plate 25. An arc-shaped groove 33 is opened in the bottom wall of the rotating bracket 3. There are three arc-shaped grooves 33, and the center of each arc-shaped groove 33 coincides with the center of the positioning hole 31. The three arc-shaped grooves 33 are part of the same ring. The center of the arc-shaped groove 33 coincides with the center of the positioning hole 31. A first bolt 34 passes through the arc-shaped groove 33. The lower end of the first bolt 34 passes through the support plate 25 and is threadedly connected to the support plate 25.

[0023] In this embodiment, after the first bolt 34 is loosened, the rotating bracket 3 can rotate around the positioning rod 31. After the first bolt 34 is tightened, the position of the rotating bracket 3 is fixed, thereby adjusting the angle of the end of the pipeline 100.

[0024] Further, refer to Figure 5The rotating bracket 3 is equipped with a movable plate 4, the position of which is longitudinally adjustable relative to the rotating bracket 3. Specifically, the side wall of the rotating bracket 3 has four symmetrical longitudinal second sliding grooves 35. The movable plate 4 includes a horizontal part 41 and a vertical part 42. Four second bolts 43 are threaded through the vertical part 42, and the ends of the four second bolts 43 pass through the four corresponding second sliding grooves 35 and are screwed with nuts (not shown in the figure). Loosening the nuts allows the longitudinal position of the movable plate 4 to be adjusted.

[0025] Further, refer to Figure 5 and Figure 6 The movable plate 4 is equipped with a bracket 5, the position of which is laterally adjustable relative to the movable plate 4. Four symmetrical third sliding grooves 44 are formed on the horizontal portion 41 of the movable plate 4. Four third bolts 51 are threaded through the bottom wall of the bracket 5, the ends of which pass through the four corresponding third sliding grooves 44 and are screwed with nuts. Loosening the nuts allows the lateral position of the bracket 5 to be adjusted.

[0026] Further, refer to Figure 6 The pipeline 100 is fixed to the bracket 5. Specifically, a base film 6 is fixed to the upper end of the bracket 5 by bolts. The pipeline 100 is placed on and in contact with the base film 6. An upper mold 7 is detachably provided at the upper end of the bracket 5. The upper mold 7 is connected and fixed to the upper end of the bracket 5 by a fourth bolt. The inner side of the upper mold 7 is in contact with the outer side of the pipeline 100. This ensures the stable placement of the pipeline 100 on the bracket 5.

[0027] When using this device, first place the pipe 100 on the bottom film 6 at the upper end of the bracket 5, and then fix the upper mold 7 to the upper end of the bracket 5 with bolts to ensure that the inner side of the upper mold 7 and the bottom film 6 are in contact with the outer side of the pipe 100, thereby fixing the pipe 100. At this time, rotate the screw 24 to drive the rotating bracket 3 at the upper end of the support plate 25 and the bracket 5 to rise. After rising to the appropriate position, loosen the first bolt 34 and the rotating bracket 3 rotates around the positioning rod 31. To adjust the orientation of pipe 100, loosen the nut at the end of the second bolt 43, adjust the longitudinal position of the moving plate 4 and bracket 5, then tighten the nut to fix the moving plate 4, thus completing the adjustment of the longitudinal position of the end of pipe 100. Next, loosen the nut at the end of the third bolt 51, adjust the lateral position of bracket 5, then tighten the nut to fix bracket 5, thus completing the adjustment of the lateral position of the end of pipe 100. This allows the end of pipe 100 to contact the welding position of the power station, enabling pipe 100 to fit more stably with the welding position, ensuring welding quality, and reducing the probability of weld seams.
