Abstract
Description
Technical Field
[0001] This invention relates to the field of welding equipment technology, specifically to welding equipment for splicing seams and its application in bridge splicing. Background Technology
[0002] Seam welding equipment is an automated welding device mainly used for welding longitudinal seams of thin-walled cylinders, conical cylinders, square tubes, flat plates, or rectangular bodies. It boasts advantages such as high welding efficiency, good welding quality, and stable welding performance.
[0003] A Chinese patent with authorization announcement number CN116944636B discloses a bridge steel box girder assembly and welding device, including a welding machine with a flux recovery device installed inside. The flux recovery device uses negative pressure to extract the flux after welding. The welding device includes a tooling plate and guide wheels. A control box is installed on top of the tooling plate and is electrically connected to the welding machine. The guide wheels are rotatably connected to the welding machine and travel along the weld. At least two pads are installed on both sides of the control box on the tooling plate, and each pad is equipped with a seat. In this invention, after two CO2 gas shielded welding passes for the root pass, the welding machine is placed on two top plates, and the welding machine is used to perform multi-pass submerged arc welding to fill and cover the weld layer, thus realizing the welding operation.
[0004] However, this welding device has the following drawbacks in practical use: 1. Existing welding equipment typically employs automated processes to improve efficiency when welding seams in spliced metal materials. However, in traditional methods, the high temperature of the welding torch after welding generates excessive heat in the welded metal, leading to poor and inaccurate inspection results when subsequent testing equipment assesses the weld quality. Furthermore, the high temperature of the weld joints can negatively impact weld quality if they fail to cool down promptly. 2. Existing welding equipment typically employs direct welding to weld seams in spliced metal materials to ensure weld quality. However, in practice, due to the long length of the metal material, the welding torch (laser welding generator) reaches high internal temperatures during prolonged operation, which can negatively impact the welding effect and lifespan of the torch.

[0043] This invention also provides the application of splice joint welding equipment in bridge splicing.
[0044] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In the application of splicing seam welding equipment in bridge splicing, when welding the gaps between spliced metal materials to achieve a stable connection, the operation of the drive motor can drive the traveling shaft and rollers to rotate, thereby moving the entire welding equipment and realizing automated welding equipment movement operation, improving the efficiency of welding gaps in metal materials. Simultaneously, when the traveling shaft rotates, the gear meshing design drives multiple cooling fan blades to rotate, automatically cooling the weld points after welding. This ensures that when subsequent welding quality inspection of the weld points is conducted by testing equipment, residual high temperatures are less likely to affect the accuracy of the inspection results. 2. In the application of splicing seam welding equipment and its use in bridge splicing, when welding the seams of metal materials using a laser welding generator, the laser welding generator can be driven by a set of DC motors to move upwards and away from the top of the metal material seam. Simultaneously, while the laser welding generator is moving upwards, another laser welding generator can be moved downwards, ensuring timely and rapid switching between different laser welding generators. This improves the service life of the laser welding generator and the welding effect when welding metal material seams. 3. In the application of splicing seam welding equipment and its use in bridge splicing, when welding the seams of metal materials, the laser welding generator can move horizontally, vertically, and rotate longitudinally as needed. This ensures that the laser welding generator can be moved to the seam of the metal material and positioned between multiple cooling fan blades for more efficient metal material welding. Furthermore, the weld point after welding can be located in the middle of multiple cooling fan blades, increasing the contact area between the weld point and the airflow, thus ensuring the effectiveness of the laser welding generator when welding the seams of the metal material. 4. In the welding equipment for splicing seams and its application in bridge splicing, when multiple cooling fan blades are used to cool the weld points at the gaps in the metal materials, the operating cooling fan blades are in an oblique position to ensure that the cooling airflow can cut into the weld point at an angle, resulting in faster cooling of the weld. Simultaneously, rapid cooling of the weld point can effectively reduce the heat-affected zone at the weld, refine the weld grains, improve the mechanical properties and corrosion resistance of the weld, and reduce the brittleness of the weld, thereby improving the quality of metal material welding.

[0069] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example 1
[0070] Please see Figures 1-12 The splicing seam welding equipment includes a concave base 10, rollers 20, a walking cooling mechanism 30, a support column 40, a seam welding mechanism 50, and a pusher 60. Multiple rollers 20 are movably connected to the inner bottom of the concave base 10. Two rollers 20 are connected to the walking cooling mechanism 30, which is installed on the side of the concave base 10. A support column 40 is installed on one side of the top of the concave base 10, and the seam welding mechanism 50 is installed on the top of the support column 40. The bottom of the seam welding mechanism 50 is located inside the concave base 10. A pusher 60 is installed on the side of the support column 40 and mounted on the top of the concave base 10. The walking cooling mechanism 30 includes an automatic walking component 70, which is installed on one side of the top of the concave base 10 and automatically moves... The walking component 70 extends to the bottom of the concave base 10, and rollers 20 are connected to the left and right sides of the automatic walking component 70; the transmission cooling component 80 is installed on the outside of the automatic walking component 70 and is movably disposed inside the concave base 10. Multiple cooling fan blades 800 are installed on the side of the transmission cooling component 80, and the multiple cooling fan blades 800 are arranged obliquely. The gap welding mechanism 50 includes a vertical moving component 90, a direction-changing compensation component 100 and a laser welding generator 110. The vertical moving component 90 is installed on the top of the support column 40, and the direction-changing compensation component 100 is installed on the side of the vertical moving component 90 by screws. Two laser welding generators 110 are installed and fixed on the inner side of the direction-changing compensation component 100.
[0071] The working principle is as follows: When welding the seams of spliced metal materials, the equipment is placed on top of the metal material, with the recessed part of the concave base 10 positioned above the metal seam. During welding, the automatic walking component 70 is activated, rotating the rollers 20 and allowing the welding equipment to move. Simultaneously, the automatic walking component 70 also drives the transmission cooling component 80 to cool the weld points, improving the accuracy of subsequent weld point inspection. While the automatic walking component 70 moves the welding equipment, the laser welding generator 110 operates, automatically welding the bottom-mounted metal seams. During actual welding, the direction-changing compensation component 100 can move the two laser welding generators 110 in different directions. If one laser welding generator 110 operates for an extended period, the system can quickly switch to the other, extending the lifespan of the laser welding generators 110 and improving the welding effect on the metal seams.
[0072] In this invention, the vertical moving component 90 can drive the laser welding generator 110 to move horizontally and vertically, making it convenient to move the laser welding generator 110 to the side of the cooling fan blade 800 and above the gap in the metal material.
[0073] For details, please refer to the following: Figure 5 and Figure 6 The automatic walking component 70 includes a side stop 701, which is welded to one side of the top of the concave base 10. A drive motor 702 is mounted on the side of the side stop 701, and the output end of the drive motor 702 is connected to a main shaft 703, which passes through the side stop 701. A first transmission belt 704 is connected to the outside of the main shaft 703 via a synchronous pulley key on its inner side. The first transmission belt 704 passes through the concave base 10, and a walking shaft 705 is connected to the inner side of the first transmission belt 704 via a synchronous pulley key. The walking shaft 705 is movably connected to the bottom of the concave base 10, and rollers 20 are connected to the left and right sides of the walking shaft 705. A transmission cooling component 80 is connected to the outer side of the walking shaft 705 via a synchronous pulley connected by a key.
[0074] In the splicing seam welding equipment of the present invention, when welding the seam of metal materials, the drive motor 702 is started to operate, driving the main shaft 703 connected to its output end to rotate. When the main shaft 703 rotates, the synchronous pulley and the first transmission belt 704 connected to its outer side will operate, thereby causing the travel shaft 705 connected to the inner side of the first transmission belt 704 through the synchronous pulley to rotate. At this time, when the travel shaft 705 rotates, the rollers 20 connected to its left and right sides will operate, driving the welding equipment to move.
[0075] For details, please refer to the following: Figure 6 and Figure 7 The transmission cooling assembly 80 includes a second transmission belt 801, which is connected to the outside of the travel shaft 705 via a synchronous pulley key located on its inner side. The second transmission belt 801 passes through the concave base 10. A longitudinal shaft 802 is connected to the inner side of the second transmission belt 801 via a synchronous pulley key. The longitudinal shaft 802 is movably disposed inside a concave groove 803, which is formed inside the concave base 10. A first bevel gear 804 is mounted on the left and right sides of the longitudinal shaft 802. Two first bevel gears 804 are provided, and the two first bevel gears 804 are meshed and connected. Both first bevel gears 804 are rotatably connected inside the concave groove 803. Rotary shaft 805 is connected to another first bevel gear 804. Rotary shaft 805 is rotatably connected inside the concave groove 803. Rotary shaft 805 and longitudinal shaft 802 are arranged perpendicularly to each other. Multiple direction-changing rotating components 806 are installed on the outer side of the rotating shaft 805, and cooling fan blades 800 are installed on the side of the direction-changing rotating components 806.
[0076] In this embodiment, the reversing rotation component 806 includes two second bevel gears 8061, which are meshed together. One second bevel gear 8061 is mounted on the outside of the rotating shaft 805, and the other second bevel gear 8061 is connected to a connecting rod 8062 on its side. The connecting rod 8062 extends to the inside of the concave base 10. A cross shaft universal joint 8063 is mounted on the side of the connecting rod 8062 and is rotatably connected to the inner wall of the concave base 10. A diagonal rod 8064 is connected to the side of the cross shaft universal joint 8063, and a cooling fan blade 800 is mounted on the side of the diagonal rod 8064.
[0077] In the above embodiment, when the rotating shaft 805 rotates, the second bevel gear 8061 mounted on its outer side rotates, causing another second bevel gear 8061, which is meshed with the side of the second bevel gear 8061, to rotate. When the other second bevel gear 8061 rotates, the connecting rod 8062 connected to its side rotates, causing the universal joint 8063 connected to the bottom of the connecting rod 8062 to rotate. At this time, when the universal joint 8063 rotates, the inclined rod 8064 and the cooling fan blade 800 connected to its bottom can rotate, cooling the welded area.
[0078] In the splicing seam welding equipment of the present invention, when the traveling shaft 705 rotates, the synchronous pulley and the second transmission belt 801 connected to its outer side will operate, causing the longitudinal shaft 802 connected to the inner side of the second transmission belt 801 via the synchronous pulley to rotate. When the longitudinal shaft 802 rotates, the first bevel gear 804 connected to its side can rotate, causing another first bevel gear 804 meshing with the side of the first bevel gear 804 to rotate. At this time, when the other first bevel gear 804 rotates, the rotating shaft 805 connected to its bottom can rotate.
[0079] For details, please refer to the following: Figure 8 and Figure 9 The vertical moving assembly 90 includes a horizontal frame 901, which is mounted on top of the support column 40.

[0081] In the above embodiment, the vertical slide 9052 can move up and down on the outside of the vertical slide rail 9051, thereby driving the assembly base 9053, which is installed on the side of the vertical slide 9052 by screws, to move up and down, adjusting the position and height of the laser welding generator 110.
[0082] In the splicing seam welding equipment of the present invention, when it is necessary to adjust the position (horizontal direction) of the laser welding generator 110, the DC motor 903 is started to operate, driving the reciprocating lead screw 904 connected to the output end of the DC motor 903 to rotate. When the reciprocating lead screw 904 rotates, the reciprocating slide 905 connected to it by ball bearings on its outer side can move horizontally, driving the laser welding generator 110 connected to the bottom of the reciprocating slide 905 to move. The design of the guide rod 906 ensures the stability of the reciprocating slide 905 during movement.
[0083] For details, please refer to the following: Figure 10 , Figure 11 and Figure 12 The reversing compensation component 100 includes two concave brackets 1001, which are mounted on the side of the mounting base 9053 by screws.

[0084] In this embodiment, a mounting base 10061 is installed on the side of the lifting slider 1006 by screws. A drive motor 10062 is installed inside the mounting base 10061. The output end of the drive motor 10062 is connected to an assembly body 10063. The assembly body 10063 is rotatably connected to the outside of the mounting base 10061. A laser welding generator 110 is assembled and fixed inside the assembly body 10063.
[0085] In the above embodiments, when it is necessary to adjust the welding angle of the laser welding generator 110, the drive motor 10062 is started to operate, which drives the assembly 10063 connected to the output end of the drive motor 10062 to rotate, thereby driving the laser welding generator 110 installed inside the assembly 10063 to rotate, and adjusting the angle of the laser welding generator 110.
[0086] In the splicing seam welding equipment of the present invention, when it is necessary to switch between different laser welding generators 110, the DC motor 1003 is started to operate, driving the transmission gear 1004 connected to the output end of the DC motor 1003 to rotate, and causing the conveyor belt 1005 meshing with the outer side of the transmission gear 1004 to move. When the conveyor belt 1005 moves, the lifting slider 1006 connected to one side of it can move up and down, and the lifting slider 1006 connected to the other side of the conveyor belt 1005 can move in the opposite direction. At this time, when the lifting slider 1006 moves up and down, the laser welding generator 110 mounted on its side can also move up and down.
[0087] For details, please refer to the following: Figure 11 The input end of the laser welding generator 110 is connected to the battery module 1101 via a wire. The battery module 1101 is mounted on the side of the mounting plate 1002 and is located on top of the DC motor 1003.
[0088] In the splicing seam welding equipment of the present invention, the battery module 1101 provides power to the laser welding generator 110, ensuring that the laser welding generator 110 can emit a laser beam to perform laser welding operations.
