Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic supports, and in particular to automatic welding equipment and a method for a reinforced concrete pile cage. Background Art

[0002] Reinforced concrete pile cages are commonly used structures in photovoltaic support infrastructure projects. They can be combined with concrete to form reinforced concrete piles, dispersing the concentrated load of photovoltaic supports.

[0003] Existing steel pile cages are typically produced using a combination of manual positioning and single-gun welding. First, the rebar and triangular bends are placed on a welding table and positioned piece by piece. Then, either manually or using a single-gun welding robot, the welds are performed point by point. Once the entire pile is welded, it is disassembled and repositioned. This results in low welding efficiency and a poor degree of automation, making it difficult to meet the demands of large-scale production.

[0004] To solve the above technical problems, patent CN119927537A proposes a photovoltaic cement pile steel cage welding tool, which reduces waiting time by alternating loading through dual positioning stations. However, this solution still uses a single welding gun to operate point by point, and the welding robot needs to move repeatedly. The single pile cycle can only be shortened to five to six minutes, so the welding efficiency improvement is limited.

[0005] In view of this, how to provide a steel pile cage welding device and a welding method that can improve the degree of welding automation and welding efficiency is a problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] like Figures 1-7 As shown, an embodiment of the present invention provides an automatic welding device for a steel pile cage. The steel pile cage 1 includes a steel bar 101 and a plurality of triangular hoops 102 arranged along the length direction of the steel bar 101. The steel bar 101 passes through the three corners of the triangular hoops 102, including:

[0054] Welding platform 2;

[0055] A plurality of fixing components 3 are provided on the welding platform 2 for clamping and fixing the steel bars 101 and the triangular bending hoops 102;

[0056] The moving mechanism 4 is arranged on the welding platform 2;

[0057] The welding mechanism 5 is arranged on the moving mechanism 4. The welding mechanism 5 has at least three welding guns. The moving mechanism 4 can drive multiple welding guns to move to the three corners of the triangular bend hoop 102 respectively. The three corners of the triangular bend hoop 102 are located outside the fixed component 3. The welding guns are used to weld the triangular bend hoop 102 and the steel bar 101.

[0058] In this embodiment, the fixing assembly 3 includes:

[0059] Multiple fixing blocks 301 are arranged on the welding platform 2. The top surface of the fixing block 301 is recessed downward to form a fixing groove 302 that is compatible with the triangular bent hoop 102. The fixing groove 302 runs through the left and right side surfaces of the fixing block 301. The fixing groove 302 is generally rectangular. The triangular bent hoop 102 is vertically set in the fixing groove 302, and its bottom edge is flush with the bottom of the fixing groove 302. Its three corners are respectively located on the left, right and top of the fixing block 301; the top surface of the fixing block 301 is recessed downward to form a positioning groove 303. The positioning groove 303 runs through the front and rear side surfaces of the fixing block 301 (and also runs through the top of the fixing groove 302), and the steel bar 101 in the top corner of the triangular bent hoop 102 is stuck in the positioning groove 303.

The end of the pneumatic pulling claw 306 passes through the welding platform 2 and extends into the steel pile cage 1. The tightening cylinder 305 is used to drive the pneumatic pulling claw 306 to move closer to or away from the steel bar 101 located at the left corner or right corner of the triangular bend hoop 102. When the pneumatic pulling claw 306 approaches the steel bar 101, its end can be hooked on the steel bar 101, and the steel bar 101 is tensioned and fixed at the left corner or right corner of the triangular bend hoop 102.

[0064] In this embodiment, multiple sets of pneumatic claws 306 are symmetrically arranged to simultaneously tension the rebar 101 in the left and right corners of the triangular bend 102. The tightening cylinder 305 has a locking function. Therefore, when the pneumatic claws 306 tighten and secure the rebar 101, they can prevent the rebar 101 from moving during the welding process, thereby improving welding stability.

There are two groups of mobile mechanisms 4, each of which is respectively arranged on the left and right sides of the steel pile cage 1. The first welding assembly 501 and the second welding assembly 502 are respectively arranged on the two groups of mobile mechanisms 4; the first welding assembly 501 has a first welding gun 503 and a second welding gun 504, and the second welding assembly 502 has a third welding gun 505; the mobile mechanism 4 is capable of driving the first welding gun 503 and the second welding gun 504 to move to two corners of the triangular bend hoop 102, and driving the third welding gun 505 to move to the other corner of the triangular bend hoop 102.

[0080] The clamp 603 is connected to the output end of the clamping cylinder 602. The clamp 603 has a clamping part that is compatible with the tube body 103. The clamping cylinder 602 is used to drive the clamp 603 close to or away from the tube body 103. When the clamp 603 is close to the tube body 103, the clamps 603 located on the left and right sides of the tube body 103 can clamp and fix the tube body 103.
