Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary devices, and in particular relates to a weld seam bonding mechanism for steel box girder components. Background Technology

[0002] As a major load-bearing component in modern bridges and large-scale building structures, steel box girders are typically assembled from multiple steel plates through welding. They possess advantages such as light weight, high strength, and good torsional resistance. During the fabrication and installation of steel box girders, various auxiliary components often need to be welded and fixed to the main steel box girder to enhance local stiffness, improve load-bearing performance, or achieve connections with other structures. The quality of the welds between these components and the steel box girder directly affects the overall safety and durability of the structure. Traditional component welding and fixing often relies on manual positioning and temporary spot welding. Due to the certain gap between the components and the steel box girder, it is difficult to achieve a tight fit during welding, which can easily lead to problems such as excessively large welds. Therefore, weld fitting mechanisms are needed during the welding process to reduce weld size.

[0003] Existing weld bonding mechanisms still have some problems during use, such as: lack of flexible angle and position adjustment capabilities, making it difficult to adapt to the installation needs of components at different angles and heights on the surface of steel box girders. Traditional fixing methods mostly use mechanical clamping or vacuum adsorption. Mechanical clamping can easily cause scratches, indentations and other damage to the coating of steel box girders or components, and is inconvenient to install in high-altitude or narrow spaces. Vacuum adsorption, on the other hand, has extremely high requirements for the flatness and cleanliness of the steel plate surface, and is prone to failure due to weak adsorption, posing safety hazards.

[0004] To address these issues, we provide a weld seam bonding mechanism for steel box girder components. Utility Model Content

[0005] The purpose of this utility model is to provide a weld seam bonding mechanism for steel box girder components. By using a rotating mechanism in conjunction with a bonding mechanism, it solves the problems of existing weld seam bonding mechanisms, such as lack of flexible angle and position adjustment capabilities, mechanical clamping that easily scratches the coating of the steel box girder or component, and vacuum adsorption that easily fails due to weak adsorption.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a weld seam bonding mechanism for steel box girder components, comprising a movable box, a rotating mechanism fixedly connected to the top of the movable box, and a seam bonding mechanism provided on one side of the rotating mechanism. The rotating mechanism includes a rotating box fixedly connected to the top of the movable box, a drive assembly disposed inside the rotating box, a rotating rod movably connected to the rotating box via a bearing, and a rotating block fixedly connected to one end of the rotating rod. The seam bonding mechanism includes a rotating plate fixedly connected to one side of the rotating block, an adjustment assembly disposed inside the rotating plate, a magnetic suction assembly disposed on one side of the rotating plate, and a pressing assembly disposed on one side of the rotating plate.

[0008] The present invention is further configured such that the driving assembly includes a driving motor fixedly connected inside the rotating box, a driving gear fixedly connected to the output end of the driving motor, and a driven gear meshing on the surface of the driving gear, and the rotating rod is fixedly connected inside the driving gear.

[0009] The present invention is further configured such that: a locking tooth is fixedly connected to the surface of the rotating block; a vertical plate is fixedly connected inside the rotating box; a first hydraulic cylinder is fixedly connected to one side of the vertical plate; an anti-moving tooth plate is fixedly connected to the output end of the first hydraulic cylinder; and an inlet / outlet slot adapted to the anti-moving tooth plate is provided on one side of the rotating box.

[0010] The present invention is further configured such that an adjustment slot is provided inside the rotating plate, and the adjustment component is located inside the adjustment slot.

[0011] The present invention is further configured such that the adjusting assembly includes an adjusting rod fixedly connected inside the rotating plate, a first adjusting block slidably connected to the surface of the adjusting rod, a second adjusting block slidably connected to the surface of the adjusting rod, and a tightening screw threadedly connected inside the first adjusting block and the second adjusting block.

[0012] The present invention is further configured such that the pressing assembly includes a second hydraulic cylinder disposed on the top of the rotating plate, and a pressure plate fixedly connected to the output end of the second hydraulic cylinder.

[0013] The present invention is further configured such that the magnetic attraction assembly includes a third hydraulic cylinder disposed on the top of the rotating plate, and an electromagnet fixedly connected to the output end of the third hydraulic cylinder.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a drive motor to drive the drive gear and driven gear to mesh and transmit power, thereby driving the rotating rod and rotating block to rotate. This enables flexible and precise adjustment of the working angle of the entire seam sealing mechanism. This movement process allows the device to quickly adapt to the welding operation requirements of steel box beams at different positions and angles. After the angle adjustment is completed, the first hydraulic cylinder pushes the anti-moving tooth plate to mesh with the locking teeth on the rotating block, firmly locking the mechanism. This effectively eliminates the possible rotation or shaking that may occur when pressure is applied in traditional mechanisms, and effectively improves the stability and positioning accuracy of the operation process.

[0016] 2. This utility model allows for independent adjustment of the horizontal position of the pressing component and the magnetic attraction component by using the first and second adjusting blocks that slide on the adjusting rod, ensuring precise alignment with the components. Subsequently, the third hydraulic cylinder drives the electromagnet to move down and attract the steel box girder, providing a strong fixing force for the device. On this basis, the second hydraulic cylinder drives the pressure plate to press the components. This sequential action process ensures that the pressing force is offset by the electromagnetic attraction force, fundamentally preventing the device from tilting, efficiently and reliably eliminating component assembly gaps, and laying the foundation for high-quality welding.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] For a specific implementation example, please refer to Implementation Example 1. Figures 1-5 This utility model is a weld seam bonding mechanism for steel box girder components, including a movable box 1, a rotating mechanism 2 fixedly connected to the top of the movable box 1, and a seam bonding mechanism 3 provided on one side of the rotating mechanism 2. The rotating mechanism 2 includes a rotating box 21 fixedly connected to the top of the movable box 1, a driving component 22 disposed inside the rotating box 21, a rotating rod 23 movably connected inside the rotating box 21 via a bearing, and a rotating block 24 fixedly connected to one end of the rotating rod 23. The seam bonding mechanism 3 includes a rotating plate 31 fixedly connected to one side of the rotating block 24, an adjusting component 32 disposed inside the rotating plate 31, a magnetic suction component 33 disposed on one side of the rotating plate 31, and a pressing component 34 disposed on one side of the rotating plate 31.

[0027] Specifically, the rotating mechanism 2 is configured to precisely adjust the angles of the rotating rod 23 and rotating block 24 via the drive component 22. This allows the sealing mechanism 3, which is fixedly connected to the rotating block 24, to flexibly adapt to the installation requirements of components at different positions and in different directions on the steel box girder. The drive motor 221 starts, driving the drive gear 222 to rotate, which in turn meshes with the driven gear 223 and drives the rotating rod 23 to rotate, ultimately achieving circumferential positioning of the rotating plate 31 and its components. The sealing mechanism 3 serves to press and temporarily fix the components. The magnetic component 33 first adheres to the surface of the steel box girder to establish stable support, and then the pressing component 34 is used to implement the sealing. The sliding of the first adjusting block 322 and the second adjusting block 323 in the component pressing operation adjustment assembly 32 on the adjusting rod 321 adjusts the electromagnet 332 to a suitable position on both sides of the component and adjusts the pressure plate 342 to a parallel position to the component. Then, the third hydraulic cylinder 331 drives the electromagnet 332 to contact the steel box girder, generating a strong magnetic attraction force when energized. The second hydraulic cylinder 341 pushes the pressure plate 342 to press the component tightly against the steel box girder to be welded. During the pressing process, the mechanism does not tilt or shift, effectively reducing the assembly gap between the component and the steel box girder, providing stable pre-fitting conditions for subsequent high-quality welding, thereby improving the reliability of weld formation and structural safety.

[0028] For a specific embodiment two, please refer to Figures 1-5Based on the first specific embodiment, the drive assembly 22 includes a drive motor 221 fixedly connected inside the rotating box 21. The motor continuously converts electrical energy into mechanical rotation on the shaft by allowing current to flow through a coil in a magnetic field and using the generated magnetic force to "push and pull" the coil to rotate. This is existing technology and will not be described in detail here. Moreover, those skilled in the art can clearly understand the working principle. A drive gear 222 is fixedly connected to the output end of the drive motor 221, and a driven gear 223 meshes with the surface of the drive gear 222. The rotating rod... 23 is fixedly connected inside the drive gear 222. Locking teeth 4 are fixedly connected to the surface of the rotating block 24. A vertical plate is fixedly connected inside the rotating box 21. A first hydraulic cylinder 5 is fixedly connected to one side of the vertical plate. An anti-moving toothed plate 6 is fixedly connected to the output end of the first hydraulic cylinder 5. An inlet / outlet slot adapted to the anti-moving toothed plate 6 is opened on one side of the rotating box 21. An adjustment slot is opened inside the rotating plate 31. An adjustment assembly 32 is located inside the adjustment slot. The adjustment assembly 32 includes an adjustment rod 321 fixedly connected inside the rotating plate 31, and a first... The system includes an adjusting block 322, a second adjusting block 323 slidably connected to the surface of the adjusting rod 321, and a tightening screw 324 threadedly connected inside the first adjusting block 322 and the second adjusting block 323. The pressing assembly 34 includes a second hydraulic cylinder 341 disposed on the top of the rotating plate 31 and a pressure plate 342 fixedly connected to the output end of the second hydraulic cylinder 341. The second hydraulic cylinder 341 is fixedly connected to the top of the first adjusting block 322. The magnetic suction assembly 33 includes a third hydraulic cylinder 331 disposed on the top of the rotating plate 31. The hydraulic cylinders utilize incompressible liquid as... The transmission medium converts fluid pressure energy into linear motion mechanical energy, which is existing technology and will not be elaborated upon in this solution. Moreover, those skilled in the art can clearly understand the working principle. The electromagnet 332, which is fixedly connected to the output end of the third hydraulic cylinder 331, is a device that uses current to generate a magnetic field. When current flows through a conductor, a magnetic field is generated around the conductor. This is existing technology and will not be elaborated upon in this solution. Moreover, those skilled in the art can clearly understand the working principle. The third hydraulic cylinder 331 is fixedly connected to the top of the second adjusting block 323.

[0029] Specifically, the drive component 22 is used to drive the rotating rod 23 to rotate. The locking teeth 4 and the anti-moving gear are used to engage the anti-moving tooth plate 6 with the locking teeth 4 after adjusting the angle of the rotating plate 31, preventing the rotating block 24 and the rotating plate 31 from shaking. The first hydraulic cylinder 5 is used to move the anti-moving tooth plate 6. The adjustment component 32 is used to adjust the positions of the magnetic attraction component 33 and the pressing component 34. The pressing component 34 is used to press the component to be welded against the steel box girder, reducing the gap between the component and the steel box girder. The magnetic attraction component 33 is used to adjust the second adjustment block 323 to the positions on both sides of the component. The third hydraulic cylinder 331 drives the electromagnet 332 downward to contact the steel box girder. The electromagnet 332 magnetically attracts the steel box girder to generate a fixing force, preventing the device from tilting when the pressing component 34 applies pressure.

[0030] The operation process of this embodiment is as follows: the moving box 1 moves the device to the welding position, the drive motor 221 is started, and the drive gear 222 is driven to rotate. The driven gear 223 meshing with it rotates accordingly, thereby driving the rotating rod 23 and the rotating block 24 fixed inside the driven gear 223 to rotate. The entire seam sealing mechanism 3 fixed to one side of the rotating block 24 is adjusted to the required working angle. After the angle is adjusted, the first hydraulic cylinder 5 is activated, pushing the anti-moving tooth plate 6 forward so that it is tightly meshed with the locking teeth 4 on the surface of the rotating block 24, thereby firmly locking the rotating block 24 and the rotating plate 31 to prevent them from shaking or shifting in subsequent operations.

[0031] Subsequently, the first adjusting block 322 and the second adjusting block 323 on the manual sliding adjusting rod 321 initially position the pressing component 34 installed on the top of the first adjusting block 322 and the magnetic attraction component 33 on the top of the second adjusting block 323 to the corresponding positions of the components to be welded. After the positions are initially determined, the tightening screw 324 is tightened to fix the first adjusting block 322 and the second adjusting block 323. Then, the third hydraulic cylinder 331 on the second adjusting block 323 is extended to push the electromagnet 332 downward until it is in close contact with the surface of the steel box girder. At this time, the electromagnet 332 is energized to generate a strong magnetic attraction force, which firmly attracts and fixes the entire mechanism to the steel box girder, providing a stable reaction force foundation for subsequent pressing. Finally, the second hydraulic cylinder 341 on the first adjusting block 322 is extended to drive the pressure plate 342 to move, continuously and stably pressing the components to be welded against the steel box girder base material, reducing the assembly gap. After the operation is completed, the pressing force and magnetic attraction force are released in reverse order, the locking mechanism is released, and the equipment can be moved away or the next positioning can be performed.
