Technical Field
[0001] This utility model relates to the field of tunnel arch frame technology, and more specifically, to an I-beam follow-up welding device. Background Technology
[0002] In numerous fields such as building construction, bridge construction, and machinery manufacturing, I-beams are a common structural material, and their welding quality directly affects the stability and safety of the entire structure. Traditional I-beam welding processes often rely on manual operation, which has many shortcomings.
[0003] Chinese utility model patent CN222903073U discloses an automatic butt welding device for I-beams. This device improves the accuracy and efficiency of I-beam welding, reduces the labor intensity of workers, and achieves the goals of reducing labor costs and improving industrial efficiency. However, this patent still has the following problems: The welding and conveying of the I-beams to the next processing site by the welding device are completed in separate steps, resulting in a disconnect between the processes. During high-intensity production, this affects the processing rhythm and prevents the production line from achieving its optimal overall efficiency, thus increasing processing costs. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, this utility model provides a follow-up welding device for I-beams. This device significantly reduces labor costs and safety hazards, and the moving welding does not affect subsequent processes at all. It optimizes the cycle time, greatly improves the overall operating efficiency of the production line, and thus achieves the goal of reducing labor costs and improving industrial efficiency.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A follow-up welding device for I-beams includes a welding frame assembly, a moving guide rail, and automatic lifting rollers. The welding frame assembly includes a welding fixture, a welding robot, and follow-up wheels. Two sets of welding fixtures are arranged side by side, and placement frames are provided on both sides of the two welding fixtures. The welding robot is mounted on the placement frames on both sides and is located between the two welding fixtures. Follow-up wheels are provided at the bottom of the welding fixtures. The welding fixtures slide on the moving guide rail via the follow-up wheels. Multiple sets of automatic lifting rollers are arranged within the moving guide rail.
[0006] The welding fixture includes a support frame, a crossbeam frame, and a top frame. The crossbeam frame is fixedly installed in the middle of the support frame, and the top frame is fixedly installed on the top of the support frame.
[0007] The placement rack is fixedly installed on both sides of the support frame.
[0008] A conveyor roller is installed at the center of the crossbeam frame.
[0009] The welding support frame is equipped with a clamping mechanism.
[0010] The fixed clamping mechanism includes an upper clamping cylinder and a side clamping cylinder. The upper clamping cylinder is fixedly mounted on the top frame, and the side clamping cylinder is fixedly mounted on the crossbeam frame. The side clamping cylinders are arranged on both sides of the conveying roller.
[0011] The placement rack is equipped with a control host, which is electrically connected to the welding robot, the follow-up moving wheels, the upper clamping cylinder, and the side clamping cylinder.
[0012] The automatic lifting idler includes a fixed base, a base frame, a hydraulic telescopic cylinder, a rotation control rod, a limit rotation rod, and an idler base. The fixed base is fixed inside the moving guide rail by bolts. The base frame is fixed on the fixed base and has a cuboid structure with openings on the top and one side wall. The hydraulic telescopic cylinder is hinged to one side wall of the base frame. The two ends of the limit rotation rod are respectively hinged to the base frame and the idler base. The two ends of the rotation control rod are respectively hinged to the telescopic end of the hydraulic telescopic cylinder and the idler base. The bottom of the rotation control rod is hinged to the limit rotation rod. An idler is mounted on the idler base.
[0013] The base frame has an opening with a limiting rod for limiting the rotation rod. The limiting rod is located on the side of the limiting rotation rod near the hydraulic telescopic cylinder.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up follow-up moving wheels and moving guide rails, the entire welding fixing frame can automatically and synchronously move towards the cold bending machine during the welding process, achieving seamless connection and efficient coordination between the welding and cold bending processes. While completing the welding, the welded I-beams are continuously and steadily and accurately transported to the entrance of the cold bending process, completely eliminating the waiting time required to stop and restart the transport after welding in the traditional process, greatly shortening the overall processing cycle and significantly improving the efficiency of the production line. The fixed clamping mechanism, composed of upper clamping cylinders and side clamping cylinders, provides strong, multi-point clamping and fixing of the top and sides of the I-beams, effectively avoiding welding defects caused by workpiece vibration and displacement during the welding process, ensuring high precision and high quality of the weld, and improving the product qualification rate. Multiple sets of automatic lifting rollers are arranged along the moving guide rail to provide continuous and reliable support and guidance for the moving I-beams, preventing the I-beams from sagging, shifting, or vibrating due to their own weight or inertia during long-distance transport. This ensured the smooth and stable movement of the I-beam from the welding station to the cold bending station, laying the foundation for subsequent cold bending accuracy; it also enhanced the production line's adaptability to different production cycles and workpiece requirements, and improved the scheduling efficiency of the production system.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0018] like Figures 1 to 5 As shown, an I-beam follow-up welding device includes a welding frame assembly, a moving guide rail 12, and an automatic lifting roller 13.

Multiple sets of automatic lifting rollers 13 are arranged in the moving guide rail 12.
[0019] The next step after welding is cold bending and cutting. Two sets of welding fixing frames 1 are fixedly connected. The I-beam is transported to the welding fixing frame 1. During the welding process of the welding robot 5, the welding fixing frame 1 can move towards the cold bending mechanism of the next process under the action of the follow-up moving wheel 7. The feeding operation is carried out at the same time during the welding process, so as to achieve seamless connection between the two processing steps.
[0020] Preferably, the welding fixing frame 1 includes a support frame 2, a crossbeam frame 3 and a top frame 4. The crossbeam frame 3 is fixedly installed in the middle of the support frame 2, and the top frame 4 is fixedly installed on the top of the support frame 2.
[0021] Preferably, the placement rack 6 is fixedly installed on both sides of the support frame 2.
[0022] Preferably, a conveyor roller 8 is provided at the center position of the crossbeam frame 3. The conveyor roller 8 is used for feeding or discharging the I-beam.
[0023] Preferably, the welding continuation bracket 1 is equipped with a fixing clamping mechanism. The fixing clamping mechanism can clamp and fix the two sections of I-beams, making them stable on the welding continuation bracket 1, which facilitates the welding continuation operation.
[0024] Preferably, the fixed clamping mechanism includes an upper clamping cylinder 9 and a side clamping cylinder 10. The upper clamping cylinder 9 is fixedly mounted on the top frame 4, and the side clamping cylinder 10 is fixedly mounted on the crossbeam frame 3. The side clamping cylinder 10 is arranged on both sides of the conveying roller.
[0025] After the I-beam is in place, the upper clamping cylinder 9 and the side clamping cylinder 10 simultaneously clamp the top and both sides of the I-beam, leaving no room for displacement and avoiding processing errors caused by displacement of the I-beam during the welding process.
[0026] Preferably, a control host 11 is installed on the placement rack 6. The control host 11 is electrically connected to the welding robot 5, the follow-up moving wheels 7, the upper clamping cylinder 9, and the side clamping cylinder. The control host 11 controls the welding process of the I-beam according to the set processing program, so that the operation of the welding and conveying cold bending machine is synchronized, which speeds up the processing pace of the I-beam and improves the processing efficiency.
[0027] Preferably, the automatic lifting idler roller 13 includes a fixed base 14, a base frame 15, a hydraulic telescopic cylinder 16, a rotation control rod 17, a limit rotation rod 18, and an idler roller base 20. The fixed base 14 is fixedly installed inside the moving guide rail 12 by bolts. The base frame 15 is fixed on the fixed base 14. The base frame 15 adopts a cuboid structure with openings on the top and one side wall. The hydraulic telescopic cylinder 16 is hinged to one side wall of the base frame 15. The two ends of the limit rotation rod 18 are respectively hinged to the base frame 15 and the idler roller base 20. The two ends of the rotation control rod 17 are respectively hinged to the telescopic end of the hydraulic telescopic cylinder 16 and the idler roller base 20.

[0028] Multiple sets of automatic lifting rollers 13 are arranged in a straight line along the moving guide rail 12. During the process of the welding support frame 1 moving on the moving guide rail 12, the automatic lifting rollers 13 can lift and transport the I-beam. When the welding support frame 1 moves to a certain automatic lifting roller 13, the automatic lifting roller 13 automatically lowers its height to make way for the welding support frame 1.
[0029] Preferably, a limiting rod 19 for limiting the limiting rotating rod 18 is provided at the opening on the base frame 15. The limiting rod 19 is provided on the side of the limiting rotating rod 18 near the hydraulic telescopic cylinder 16.
[0030] After the H-beam detects a material shortage, the cold bending machine stops working and the H-beam is conveyed to the welding support frame 1. The side clamping cylinder 10 clamps the H-beam towards the center, and the upper clamping cylinder 9 clamps the upper part of the H-beam. The welding robots 5 on both sides automatically weld the butt joint of the H-beam. During the welding process, the welding support frame 1 moves along the moving guide rail 12 towards the cold bending machine under the action of the follower moving wheel 7. The welding support frame 1 moves with the H-beam, and the moving speed of the H-beam, the moving speed of the welding support frame 1, and the cold bending speed of the cold bending machine are kept consistent. Multiple automatic lifting rollers 13 are installed in the moving guide rail 12 between the welding support frame 1 and the cold bending machine. When the welding support frame 1 moves to a certain automatic lifting roller 13, the automatic lifting roller 13 automatically descends. After the H-beam welding is completed, the upper clamping cylinders 9 and the side clamping cylinders 10 on both sides are released, the welding fixing frame 1 moves back to the initial position, and the automatic lifting roller 13 automatically rises to complete the automatic welding of the H-beam. It waits for the next detection of material shortage to repeat the automatic welding of the H-beam.
