Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to an automatic welding equipment and method for reinforced concrete pile cages. Background Technology

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

[0003] Currently, the production of reinforced concrete pile cages generally employs a combination of manual positioning and single-gun welding during the welding process. First, the reinforcing bars and triangular hoops are placed on a welding table and positioned piece by piece. Then, manual labor or a single-gun welding robot welds each point individually. After the entire pile is welded, it is disassembled and repositioned. This method suffers from low welding efficiency and poor automation, making it difficult to meet the demands of large-scale production.

[0004] To address the aforementioned technical issues, patent CN119927537A proposed a welding fixture for the steel cage of photovoltaic cement piles. This fixture reduces waiting time by alternating material feeding at dual positioning stations. However, this solution still uses a single welding gun for point-by-point operation, requiring the welding robot to perform repeated actions. The cycle time for a single pile can only be shortened to five to six minutes, thus limiting the improvement in welding efficiency.

[0005] Therefore, how to provide a welding equipment and method for reinforcing steel pile cages that can improve the degree of welding automation and welding efficiency is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic welding device and method for reinforced concrete pile cages to solve the problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides an automatic welding device for a reinforced concrete pile cage. The reinforced concrete pile cage includes reinforcing bars and a plurality of triangular hoops arranged along the length of the reinforcing bars. The reinforcing bars pass through the three corners of the triangular hoops, including:

[0010] A moving mechanism is mounted on the welding platform;

[0011] A welding mechanism is provided on the moving mechanism. The welding mechanism has at least three welding torches. The moving mechanism can drive the multiple welding torches to move to the three corners of the triangular hoop. The three corners of the triangular hoop are located outside the fixed component. The welding torches are used to weld the triangular hoop to the reinforcing bars.

[0012] Furthermore, the fixing component includes:

[0013] Multiple fixing blocks are disposed on the welding platform. The top surface of each fixing block is recessed downward to form a fixing groove that fits the triangular hoop. The fixing groove extends through the left and right sides of the fixing block. The triangular hoop is disposed in the fixing groove, with its three corners located on the left, right, and top sides of the fixing block, respectively. The top surface of each fixing block is recessed downward to form a positioning groove. The positioning groove extends through the front and rear sides of the fixing block. The reinforcing bar in the uppermost corner of the triangular hoop is inserted into the positioning groove.

[0015] An inclined support is inclinedly installed on the lower surface of the welding platform;

[0016] A fastening cylinder is mounted on the inclined bracket;

[0017] A pneumatic claw is connected to the output end of the fastening cylinder. The end of the pneumatic claw passes through the welding platform and extends into the steel pile cage. The fastening cylinder is used to drive the pneumatic claw to approach or move away from the steel bar located at the left or right corner of the triangular bend. When the pneumatic claw approaches the steel bar, its end can hook onto the steel bar and make the steel bar tensioned and fixed at the left or right corner of the triangular bend.

[0018] Furthermore, the fixing component also includes:

[0019] An inclined guide rail is provided on the inclined support along the length direction of the pneumatic claw;

[0020] The support slider is slidably mounted on the inclined guide rail;

[0024] A first mobile platform is slidably mounted on a first mobile guide rail, and the first mobile platform is driven by a first servo motor to slide along the first mobile guide rail.

[0025] The second moving guide rail is set on the first moving platform in a direction perpendicular to the steel pile cage;

[0026] The second moving platform is slidably mounted on the second moving guide rail, and the second moving platform is driven by the second servo motor to slide along the second moving guide rail; the welding mechanism is mounted on the second moving platform.

[0027] Furthermore, the welding mechanism includes a first welding component and a second welding component, and two sets of moving mechanisms are respectively arranged on the left and right sides of the reinforced concrete pile cage. The first welding component and the second welding component are respectively arranged on the two sets of moving mechanisms. The first welding component has a first welding gun and a second welding gun, and the second welding component has a third welding gun. The moving mechanism can drive the first welding gun and the second welding gun to move to two corners of the triangular bend, and drive the third welding gun to move to the other corner of the triangular bend.

[0028] Furthermore, the steel reinforcement pile cage also includes a pipe body, and the tail end of the steel reinforcement is fixed to the pipe body; the welding platform is provided with a pipe body fixing mechanism for fixing the pipe body.

[0029] Furthermore, the tube fixing mechanism includes:

[0030] A support is adapted to the pipe body, and the pipe body is disposed on the support;

[0031] Multiple clamping cylinders are mounted on the welding platform and arranged on the left and right sides of the pipe body;

[0032] The clamp is connected to the output end of the clamping cylinder. The clamp has a clamping part adapted to the tube body. The clamping cylinder is used to drive the clamp to move closer to or away from the tube body. When the clamp moves closer to the tube body, the clamps located on the left and right sides of the tube body can clamp and fix the tube body.

[0033] Furthermore, it also includes:

[0034] A fume collection mechanism is installed on the welding platform to collect the fumes generated during welding.

[0035] The present invention also provides an automatic welding method for reinforced concrete pile cages, which utilizes the automatic welding equipment for the reinforced concrete pile cages and includes the following steps:

[0036] S1: Secure the steel pile cage to the welding platform using the fixing components;

[0038] S3: Welding triangular bends and reinforcing bars using multiple welding torches;

[0039] S4: Repeat steps S2-S3 to weld all triangular hoops and reinforcing bars.

[0040] The present invention discloses the following technical effects:

[0041] This invention features a specially designed fixing component for reinforced concrete pile cages. This component automatically positions the triangular bends and exposes the three corners (welding points) of the bends on the outside of the fixing component. A moving mechanism then moves the welding torch to the three corners of the positioned triangular bends to weld the bends and the reinforcing bars. Compared with existing technologies, this invention achieves automatic positioning of the triangular bends and fully automated welding of the reinforced concrete pile cages, significantly improving welding efficiency.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

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

[0054] Welding platform 2;

[0055] Multiple fixing components 3 are set on the welding platform 2 for clamping and fixing the reinforcing bar 101 and the triangular bend 102;

The three corners of triangular hoop 102 are located outside the fixed component 3. Welding guns are used to weld triangular hoop 102 and reinforcing bar 101.

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

[0059] Multiple fixing blocks 301 are set on the welding platform 2. The top surface of the fixing block 301 is recessed downward to form a fixing groove 302 that matches the triangular bend 102. The fixing groove 302 extends through the left and right sides of the fixing block 301. The fixing groove 302 is roughly rectangular.

There are two sets of moving mechanisms 4, which are respectively arranged on the left and right sides of the reinforced concrete pile cage 1. The first welding component 501 and the second welding component 502 are respectively arranged on the two sets of moving mechanisms 4. The first welding component 501 has a first welding gun 503 and a second welding gun 504, and the second welding component 502 has a third welding gun 505.
