[0021] Specifically, the linear module 41 is operated to drive the through hole 46 to move above the welding hole position on the tower plate, and the laser indicator 47 is turned on to project light onto the tower plate. The user makes further adjustments to make the through hole 46 coincide with the hole position, and inserts the riser pipe to be welded from the through hole 46 until the bottom of the riser pipe fits tightly with the hole position. In this way, the riser pipe can be positioned to facilitate subsequent welding.

[0022] In this embodiment, the driving mechanism 5 includes a groove 51, a driving motor 52, a threaded rod 53, a threaded slider 54 and a support block 55. The front side of the bottom plate 1 is provided with a groove 51, and the driving motor 52 is fixedly installed on the left side of the inner wall of the groove 51. The output end of the driving motor 52 is fixedly installed with a threaded rod 53 having one end rotatably connected to the right side of the inner wall of the groove 51.

[0023] A limiting groove is provided at the front end of the top of the bottom plate 1 , and a limiting block having one end fixedly connected to the bottom of the linear module 41 is slidably installed inside the limiting groove.

[0024] Specifically, the drive motor 52 is started to rotate the threaded rod 53, and the threaded rod 53 drives the threaded slider 54 to move the linear module 41 horizontally; the limit groove and the limit block can position the moving direction of the linear module 41, so that the linear module 41 is more stable when moving horizontally.

[0025] In this embodiment, the fixing mechanism 3 includes a U-shaped block 31, a hydraulic push rod 32 and a pressing block 33. The U-shaped blocks 31 are fixedly installed on the left and right ends of the front and the left and right ends of the back of the placement rack 2.

[0026] Specifically, the tower plate is placed on top of the placement frame 2, and the hydraulic push rods 32 on all sides are operated to move the pressing blocks 33 downward to fix the tower plate, thereby facilitating subsequent welding operations on the tower plate.

[0027] The working principle of the above embodiment is:

[0028] (1) Place the tower plate on top of the placement rack 2, and operate the hydraulic push rods 32 around it to move the pressing block 33 downward to fix the tower plate;

[0029] (2) Start the drive motor 52 to rotate the threaded rod 53, and the threaded rod 53 drives the threaded slider 54 to move the linear module 41 horizontally. The linear module 41 is operated to drive the through hole 46 to move to the hole position welded on the tower plate. The laser pointer 47 is turned on to project light onto the tower plate. The user makes further adjustments to make the through hole 46 coincide with the hole position.

[0030] (3) Insert the riser pipe to be welded from the through hole 46 until the bottom of the riser pipe fits tightly with the hole position, and the positioning operation of the riser pipe is completed. The welding of the riser pipe can be completed using welding equipment;

[0031] (4) In addition, since the tower plate and the riser are basically made of corrosion-resistant stainless steel, before welding, turning on the resistance wire heating block 44 to preheat the welding area can eliminate part of the thermal stress and reduce deformation and cracks that may occur during the welding process.
