Description

Technical Field

[0001] This invention relates to the field of bridge construction welding technology, and in particular to a welding equipment for assembling steel-concrete bridges in high-altitude and cold regions. Background Technology

[0002] To address the harsh environment of steel-concrete bridge assembly in high-altitude and frigid regions, a specialized welding device was developed. This device features a reinforced design resistant to low temperatures and oxygen deficiency, with core components specially treated to ensure stable operation in temperatures as low as -40°C and in thin air. Equipped with an intelligent temperature control system, it automatically adjusts welding parameters to adapt to environmental changes, ensuring weld quality. The device boasts highly efficient automated welding capabilities, and combined with high-precision positioning technology, it can accurately complete welding operations on complex steel structure nodes, significantly improving construction efficiency. Furthermore, its lightweight and portable design facilitates transportation and installation in high-altitude mountainous areas. Field verification has demonstrated that this device effectively overcomes the adverse effects of high-altitude and frigid environments on welding operations, ensuring the smooth progress of bridge assembly projects.

[0003] In practical applications, existing equipment often uses track-type automatic welding equipment during bridge assembly. However, in high-altitude and cold regions, the climate is extremely harsh, and the tracks used by the welding equipment are prone to snow accumulation due to snowfall. Snow accumulation can obscure the key markings and outlines of the tracks, increasing the difficulty of positioning the equipment and the risk of operational errors. Therefore, a welding equipment for steel-concrete bridge assembly in high-altitude and cold regions is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the use of track-type automatic welding equipment in the assembly process of bridges. However, in high-altitude and cold regions, where the climate is extremely harsh, the tracks used by the welding equipment are prone to snow accumulation due to snowfall. Snow accumulation can obscure the key markings and outlines of the tracks, increasing the difficulty of positioning the equipment and the risk of operational errors. Therefore, this invention proposes a welding equipment for assembling steel-concrete bridges in high-altitude and cold regions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A welding device for assembling steel-concrete bridges in high-altitude and cold regions includes a track. Counterweight plates are fixedly connected to both sides of the track. Reinforcing shells are located on both sides of the counterweight plates. A second motor is housed inside each reinforcing shell. A first gear is located at the output end of the second motor. Second gears are meshed with both sides of the first gear. An eccentric wheel is fixedly connected to each of the second gears. The eccentric wheel is rotatably connected to the reinforcing shell. A vibrating rod is located on one side of the eccentric wheel and is slidably connected to the reinforcing shell. A spring is fixedly connected between the reinforcing shell and the vibrating rod. A threaded rod is fixedly connected to the upper part of the first gear, and a moving part is threadedly connected to the threaded rod. A reinforcing pressure plate is fixedly connected to the front end of the moving part. During the track installation process, the second motor is started to drive the first gear to rotate. The rotation of the first gear drives the threaded rod and the second gear to rotate synchronously. The rotation of the threaded rod drives the reinforcing pressure plate to press down, thereby compressing both sides of the track to achieve track reinforcement. At the same time as reinforcement, the second gear synchronously drives the vibrating rod to vibrate, thereby causing the track to vibrate slightly during reinforcement, causing the snow to fall off. The front end of the vibrating rod is equipped with an impact head to effectively prevent damage to the counterweight plate during the impact of the vibrating rod. The upper part of the reinforcing shell is provided with a mounting hole, through which the reinforcing shell is installed on the bridge surface. An anti-slip pad is fixedly connected to the lower part of the reinforcing pressure plate.

[0006] The above technical solution further includes: The rear end of the moving part is rotatably connected to two rotating wheels, and a limit plate is provided at the middle position of the two rotating wheels. The limit plate is fixedly connected to the reinforced shell.

[0007] A damping shell is fixedly connected to the front end of the reinforced shell, and a buffer pad is provided at the front end of the damping shell.

[0008] A piston is slidably connected inside the damping housing. A guide rod is fixedly connected to the piston. A buffer pad is fixedly connected to the end of the guide rod away from the piston. A damping medium is provided inside the damping housing. A spring can be provided between the piston and the damping housing to allow the piston to return to its original position.

[0009] The piston has a damping hole at the top, and sealing plates are fixedly connected to both sides of the damping housing. The sealing plates have good sealing performance.

[0010] A movable housing is provided on the upper part of the track, and a robotic arm is fixedly connected to the upper part of the movable housing. A welding head is provided on the upper part of the robotic arm, and a control system is provided on the lower part of the robotic arm. The control system realizes the automatic steering and movement of the robotic arm, thereby realizing the automatic welding of the welding head.

[0011] The upper part of the movable housing is provided with a first motor, and the output end of the first motor is provided with a moving wheel, which is connected to the track for transmission.

[0012] A driven wheel is rotatably connected to the upper part of the movable housing, and the driven wheel is connected to the track via a transmission connection.

[0013] The upper part of the movable housing is fixedly connected to a collision head, and the two ends of the track are fixedly connected to collision plates.

[0014] The present invention has the following beneficial effects: 1. In this invention, during the installation of the track, the track is first laid on the bridge connection surface. Then, a reinforcing shell is installed according to the track position. After the reinforcing shell is installed, the second motor is started to drive the first gear to rotate. The rotation of the first gear drives the threaded rod and the second gear to rotate synchronously. The rotation of the threaded rod drives the reinforcing pressure plate to move downward, thereby pressing the upper part of the fixed counterweight plate to reinforce and stabilize the track. This effectively prevents the strong wind environment in high-altitude and cold regions from affecting the stability of the device. At the same time as the reinforcing pressure plate is reinforcing, the second gear can synchronously drive the vibrating rod to move back and forth, thereby impacting both sides of the counterweight plate at high speed, causing the track to vibrate. This achieves reinforcement while driving the track to vibrate, shaking off any snow that may be attached to the track.

[0015] 2. In this invention, starting the first motor can drive the moving wheel to rotate, thereby moving the moving housing and adjusting the welding position of the welding head. Moreover, the control system set at the lower part of the robotic arm can also adjust the welding point of the welding head, effectively improving the welding flexibility and accuracy, and improving the use effect of the device.

[0018] 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.

[0019] Example 1 like Figures 1-7 As shown, a welding device for assembling steel-concrete bridges in high-altitude and cold regions includes a track 1. Counterweight plates 5 are fixedly connected to both sides of the track 1. Reinforcing housings 6 are provided on both sides of the counterweight plates 5. A second motor 17 is installed inside the reinforcing housing 6. A first gear 18 is provided at the output end of the second motor 17. Second gears 19 are meshed on both sides of the first gear 18. An eccentric wheel 20 is fixedly connected to the second gear 19. The eccentric wheel 20 is rotatably connected to the reinforcing housing 6. A vibration rod 21 is provided on one side of the eccentric wheel 20. The vibration rod 21 is slidably connected to the reinforcing housing 6. A spring 22 is fixedly connected between the reinforcing housing 6 and the vibration rod 21. A threaded rod 16 is fixedly connected to the upper part of the first gear 18. A moving part 13 is threadedly connected to the threaded rod 16. A reinforcing pressure plate 12 is fixedly connected to the front end of the moving part 13. During the installation of the track 1, the second motor 17 is started, driving the first gear 18 to rotate.

[0020] The rotation of the first gear 18 drives the threaded rod 16 and the second gear 19 to rotate synchronously. The rotation of the threaded rod 16 drives the reinforcing pressure plate 12 to press down, thereby compressing both sides of the track 1 to reinforce the track 1. At the same time, the second gear 19 drives the vibrating rod 21 to vibrate, thereby causing the track 1 to vibrate slightly during reinforcement, causing the snow to fall off. The front end of the vibrating rod 21 is equipped with an impact head to effectively prevent damage to the counterweight plate 5 during the impact of the vibrating rod 21. The upper part of the reinforcing housing 6 is provided with a mounting hole, through which the reinforcing housing 6 is installed on the bridge surface. The lower part of the reinforcing pressure plate 12 is fixedly connected with an anti-slip pad. The rear end of the moving part 13 is rotatably connected to two rotating wheels 15. A limit plate 14 is provided in the middle of the two rotating wheels 15, and the limit plate 14 is fixedly connected to the reinforcing housing 6.

[0021] In this embodiment, during the installation of track 1, track 1 is first laid on the bridge connection surface. The counterweight plates 5 set on both sides of track 1 can initially ensure the stability of track 1. Then, the reinforcing housing 6 is installed according to the position of track 1. After the reinforcing housing 6 is installed, the second motor 17 is started, which drives the first gear 18 to rotate. The rotation of the first gear 18 drives the threaded rod 16 and the second gear 19 to rotate synchronously. The rotation of the threaded rod 16 drives the threaded moving part 13 to move. During the movement of the moving part 13, the rotating wheel 15 set at the rear end can be synchronously driven along the limiting plate 14, effectively ensuring the stability of the moving part 13. The stability during movement is achieved by moving the movable part 13, which drives the fixedly connected reinforcing plate 12 to move downward, thereby pressing the upper part of the fixed counterweight plate 5 to reinforce and stabilize the track 1. This effectively prevents the stability of the track 1 from being affected by strong winds in high-altitude and cold regions. At the same time as the reinforcing plate 12 reinforces the track, the second gear 19 can simultaneously drive the eccentric wheel 20 to rotate. The rotation of the eccentric wheel 20, combined with the reset of the spring 22, enables the vibrating rod 21 to move back and forth, thereby impacting both sides of the counterweight plate 5 at high speed, causing the track 1 to vibrate. This achieves reinforcement while driving the track 1 to vibrate, shaking off any snow that may be attached to the track 1.

[0022] Example 2 like Figures 1-7 As shown, a damping housing 23 is fixedly connected to the front end of the reinforced housing 6. A buffer pad 24 is provided at the front end of the damping housing 23. A piston 25 is slidably connected inside the damping housing 23. A guide rod 26 is fixedly connected to the piston 25. A buffer pad 24 is fixedly connected to the end of the guide rod 26 away from the piston 25. A damping medium is provided inside the damping housing 23. A spring 22 can be provided between the piston 25 and the damping housing 23 to reset the piston 25. A damping hole 27 is provided on the upper part of the piston 25. Sealing plates 28 are fixedly connected to both sides of the damping housing 23. The sealing plates 28 have good sealing performance.

[0023] A movable housing 7 is installed on the upper part of the track 1. A robotic arm 2 is fixedly connected to the upper part of the movable housing 7. A welding head 3 is installed on the upper part of the robotic arm 2. A control system is installed on the lower part of the robotic arm 2. The control system realizes the automatic steering and movement of the robotic arm 2, thereby realizing the automatic welding of the welding head 3. A first motor 8 is installed on the upper part of the movable housing 7. A movable wheel 9 is installed at the output end of the first motor 8. The movable wheel 9 is connected to the track 1 through transmission. A driven wheel 10 is rotatably connected to the upper part of the movable housing 7. The driven wheel 10 is connected to the track 1 through transmission. A collision protection head 11 is fixedly connected to the upper part of the movable housing 7. Collision protection plates 4 are fixedly connected to both ends of the track 1.

[0024] In this embodiment, a damping shell 23 is provided at the front end of the reinforced shell 6. Under the vibration generated by the movement of the movable shell 7 in a strong wind environment, the buffer plate 24 can be moved. The movement of the buffer plate 24 can drive the piston 25, which is fixedly connected to the guide rod 26, to move. During the movement of the piston 25, the damping medium inside the damping shell 23 generates throttling resistance through the damping hole 27, which consumes the kinetic energy generated by the vibration, achieves buffering, and effectively ensures the stability of the track 1 in a high-altitude environment.

[0025] When the device is welding, starting the first motor 8 can drive the moving wheel 9 to rotate, thereby moving the moving housing 7 and adjusting the welding position of the welding head 3. Moreover, the control system set at the lower part of the robotic arm 2 can also adjust the welding point of the welding head 3, effectively improving the welding flexibility and accuracy, and improving the use effect of the device.
