[0002] Photovoltaics is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Photovoltaic installation requires support brackets, which are fixed to the ground using grouting piles.

[0003] To increase the stability of the connection with the ground, existing photovoltaic cast-in-place piles generally have helical blades laser-welded onto the outer wall of the pile to form an integrated structure. The drill bit structure at one end of the pile can be easily screwed into the deep soil layer. However, the welding of the photovoltaic cast-in-place pile and the helical blade is mostly done manually, which results in low welding efficiency. The helical blade and the photovoltaic cast-in-place pile are prone to positional misalignment, affecting the accuracy and quality of the welding.

[0004] Therefore, a laser welding device for processing drill bit-type spiral integrated photovoltaic grouting piles is proposed. Utility Model Content

[0008] Preferably, the limiting hole, the threaded blade retaining ring, and the round hole of the photovoltaic injection pile are all on the same horizontal axis.

[0009] Preferably, the top of the moving platform has a groove near the outer side of the gear, the groove is connected to the circular hole, and the gear and the gear ring are connected by gear teeth meshing.

[0010] Preferably, there are a total of eight electric push rods one and eight electric push rods two, and the eight electric push rods one and eight electric push rods two are arranged in groups of four symmetrically on the outer side walls of the moving plate and the moving platform.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a laser welding device for processing drill bit-type spiral integrated photovoltaic grouting piles, such as... Figure 1-4As shown, the system includes a base 1, a fixed plate 2 bolted to the top of the base 1, and a servo motor 3 bolted to the center of one outer wall of the base 1. A ball screw 4 is bolted to the output end of the servo motor 3. A moving plate 5 is bolted to the nut seat on the ball screw 4. A photovoltaic grouting pile limiting hole 6 is provided at the center of one outer wall of both the moving plate 5 and the fixed plate 2. Electric push rod 7 and electric push rod 9 are bolted to the outer sides of one outer wall of both the moving plate 5 and the fixed plate 2, near the outer side of the photovoltaic grouting pile limiting hole 6. Electric push rod 7 is located to the side of electric push rod 9, and a chuck 8 is bolted to the output end of electric push rod 7. Electric push rod 9 is bolted to the output end of electric push rod 9, and a threaded blade retaining ring 10 is bolted to the output end of electric push rod 9. A fixed seat 11 is bolted to the outer wall of the base 1 adjacent to the servo motor 3. A servo motor 12 is bolted to one side of the outer wall near the servo motor 3. A ball screw 13 is bolted to one side of the servo motor 12. A moving platform 14 is bolted to the nut seat on the ball screw 13. The moving plate 5 and the moving platform 14 are slidably connected to the base 1. There are eight electric push rods 7 and 9 in total. The eight electric push rods 7 and 9 are arranged symmetrically in groups of four on the outer walls of the moving plate 5 and the moving platform 14. A circular hole 15 is opened in the center of one side of the outer wall of the moving platform 14. A stepper motor 16 is bolted to the top of the moving platform 14. A gear 17 is bolted to one side of the stepper motor 16. A rotating ring 18 is set inside the circular hole 15. A gear ring 19 is welded to the outer wall of the rotating ring 18. A laser welding head 20 is bolted to the inner wall of one side of the rotating ring 18.

[0022] It should be noted that, since most existing photovoltaic cast-in-place piles and helical blades are welded manually, the welding efficiency is low, and the helical blades and photovoltaic cast-in-place piles are prone to positional misalignment, affecting the welding accuracy and quality. In this embodiment, the helical blades on the photovoltaic cast-in-place pile rod are limited by the threaded blade retaining ring 10, which can ensure that the pile rod and the helical blades are in a relatively fixed state, avoiding positional misalignment of the pile rod and the threaded blades that affects the welding accuracy. When the laser welding head 20 rotates axially, it makes horizontal linear motion, so that the laser beam irradiated by the laser welding head 20 on the pile rod is helical, thereby performing laser welding at the joint of the pile rod and the helical blades, realizing the integrated welding of the photovoltaic cast-in-place pile.

[0023] Specifically, in this embodiment, the solution mainly includes a fixed plate 2, a movable plate 5, a movable stage 14, and a laser welding head 20. During use, the distance between the fixed plate 2 and the movable plate 5 is adjusted according to the length of the photovoltaic injection pile. During adjustment, the servo motor 3 drives the ball screw 4 to rotate through its output end on one side. The movable plate 5 on the ball screw 4 moves on the base 1, and the spiral blades are fitted onto the photovoltaic injection pile shaft, with the pile shaft passing through the photovoltaic injection pile limiting hole 6 on the movable plate 5 and the movable stage 14. Each group of four electric push rods 7 works synchronously. The electric push rod 7 drives the chuck 8 to move through its output end on one side. The chuck 8 positions and clamps the pile shaft. After fixing both ends of the pile shaft, each group of four electric push rods 9 works synchronously. The electric push rod 9 drives the threaded blade retaining ring 10 to move through its output end on one side, controlling the two threaded blades... The retaining rings 10 move towards each other, thereby limiting the position of the threaded blades on the outer wall of the pile rod, preventing positional displacement between the pile rod and the threaded blades from affecting the welding accuracy. During laser welding, the servo motor 12 drives the ball screw 13 to rotate through its output end on one side. The moving table 14 on the ball screw 13 moves on the base 1. When the moving table 14 moves linearly, the stepper motor 16 drives the gear 17 to rotate through its output end on one side. Through the meshing connection between the gear 17 and the gear ring 19, the rotation of the gear 17 drives the gear ring 19 to rotate, and the rotating ring 18 rotates synchronously. The laser welding head 20 on the rotating ring 18 rotates axially, and the linear movement of the moving table 14 makes the laser beam irradiated by the laser welding head 20 onto the pile rod spiral, thereby realizing the laser welding of the pile rod and the threaded blades, and realizing the integrated welding of the photovoltaic grouting pile.

[0024] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the photovoltaic grouting pile limiting hole 6, the threaded blade retaining ring 10, and the round hole 15 are all on the same horizontal axis.

[0025] In this embodiment, the photovoltaic grouting pile limiting hole 6, the threaded blade retaining ring 10, and the circular hole 15 on the same horizontal axis can make the photovoltaic grouting pile limited inside the photovoltaic grouting pile limiting hole 6 and the threaded blade tightly connected, and make the laser welding head 20 move circumferentially along the center of the photovoltaic grouting pile and the threaded blade.

[0026] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the top of the moving platform 14 has a groove near the outer side of the gear 17. The groove and the round hole 15 are connected and pass through each other. The gear 17 and the gear ring 19 are connected by gear teeth meshing. The rotating ring 18 and the round hole 15 are connected by an annular groove and a slider slidingly.

[0027] In this embodiment, the meshing connection enables the gear 17 to drive the gear ring 19 to rotate, thereby realizing the rotation of the gear ring 19, and the sliding connection ensures the stability of the rotation of the rotating ring 18.
