Description

Technical Field

[0001] This utility model belongs to the technical field of welding operation table, specifically relating to a welding operation table for a large-span truss structure. Background Technology

[0002] A welding workbench for large-span truss structures is a specialized piece of equipment used to support and fix large-span truss structures for welding operations. With the continuous development of modern architecture, industrial facilities, and bridges, the application of large-span truss structures is becoming increasingly widespread. These structures typically have large spans and complex geometries, thus requiring specialized support and positioning equipment during the welding process to ensure welding quality and construction safety. Large-span truss structures are widely used in large buildings and infrastructure such as stadiums, exhibition centers, airport terminals, and bridges. These structures are usually made of steel or aluminum alloys, possessing lightweight, high strength, and good resistance to deformation.

[0003] The welding workbenches for large-span truss structures on the market require a lot of time for manual adjustment for trusses of different sizes, shapes and welding requirements. This is inefficient and it is difficult to ensure the accuracy of the adjustment, resulting in low welding efficiency and affecting the quality. During the welding process, stress is generated on the workbench. If the overall structural rigidity of the workbench is not sufficient, it is prone to deformation under long-term use or when subjected to large loads. At the same time, welding waste may be piled up randomly in the work area, which not only affects the cleanliness of the work environment, but also poses safety hazards to operators, such as tripping or being cut.

[0004] Therefore, it is of great importance to design a large-span truss structure welding workbench to solve the above-mentioned defects. Utility Model Content

[0005] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide a welding operation table for large-span truss structures. This welding operation table aims to solve the problem that existing welding operation tables for large-span truss structures require a lot of time for manual adjustments, resulting in low efficiency and difficulty in ensuring the accuracy of the adjustments.

[0006] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a welding operation table for a large-span truss structure. The welding operation table includes a frame; a control panel is provided on one side of the front end face of the frame near the top; a welding operation structure is provided in the center of the inside of the frame; and a waste collection structure is provided on one side of the center of the lower end face of the frame. The welding operation structure includes a first stabilizing frame, which is located on one side of the center of the inner wall of the frame. A rotator is located inside the frame at the center of the upper end face of the first stabilizing frame. A rotating shaft is fixedly connected to the output end of the rotator. A first bearing is sleeved on one end of the rotating shaft. A second stabilizing frame is located inside the frame on the outer wall of the first bearing.

[0007] When using the welding workbench of this technical solution, the rotating shaft is driven to rotate by the rotator. In conjunction with the rotating plate, connecting rod, placement rack and sliding adjustment placement platform, the workpiece can be fixed and its position adjusted flexibly. The counterweight and limit block ensure stability and accuracy. In addition, the scrap bin can be flexibly slid through the slide and slider for easy cleaning. The overall design improves welding accuracy, stability and the convenience of scrap disposal.

[0008] Preferably, the waste collection structure includes a waste rack, which is located at the center of the lower end face of the frame on one side. Slides are provided at the center of both inner side walls of the waste rack, and a waste bin is provided at the center of the inside of the waste rack.

[0009] Furthermore, rotating plates are provided on both sides of the center of the outer side wall of the rotating shaft, and second bearings are provided on the front and rear sides of the center of one side wall of each of the two rotating plates. Connecting rods are provided between the four second bearings, and placement racks are fitted on the outside of the two connecting rods.

[0010] Furthermore, each of the two placement racks has a sliding groove at the center of its upper end face, and multiple placement platforms are slidably connected to the center of each of the two sliding grooves. Adjusting bolts are provided on the upper sides of both the front and rear sides of the multiple placement platforms.

[0011] Furthermore, counterweights are provided at the center of the lower end face of both placement racks.

[0014] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model's welding workbench, through a flexible and positionable placement platform, allows operators to precisely adjust the position of the truss to be welded within a chute according to its specific dimensions, shape, and welding requirements. The truss is then secured with adjusting bolts, enhancing adaptability to different truss specifications and effectively ensuring the accuracy of workpiece positioning during welding, thereby improving welding precision and quality. Furthermore, multiple bearings working in conjunction with a stabilizing frame ensure stable rotation of the rotating shaft, while limit blocks restrict the rotation angle of the connecting rod to prevent excessive rotation. A counterweight maintains the balance of the entire rotating structure, allowing the placement frame to smoothly rotate and adjust the truss. This facilitates welding of different trusses, reduces the number of adjustments required, and ensures both welding stability and precision while improving efficiency. Simultaneously, a sliding waste bin design allows for timely collection of waste during welding. During cleaning, operators can easily pull or push the waste bin along the slide using a slider, keeping the work area clean and improving the quality of the working environment.

[0017] This specific embodiment is a welding operation platform for a large-span truss structure, and its structural schematic diagram is shown below. Figure 1-6As shown, the welding workbench includes a frame 1, a control panel 2 is provided on one side of the front end face of the frame 1, a welding operation structure 3 is provided in the center of the interior of the frame 1, and a waste collection structure 4 is provided on one side of the center of the lower end face of the frame 1.

[0018] First, in this embodiment, the specific structure of welding operation structure 3 is as follows: The welding operation structure 3 includes a first stabilizing frame 301, which is located on one side of the center of the lower inner wall of the frame 1. A rotator 302 is provided inside the frame 1 at the center of the upper end face of the first stabilizing frame 301. A rotating shaft 303 is fixedly connected to the output end of the rotator 302. A first bearing 305 is sleeved on one end of the rotating shaft 303. A second stabilizing frame 304 is provided inside the frame 1 on the outer side of the first bearing 305. The first stabilizing frame 301 provides support. When operation is required, the rotator 302 is started to drive the fixedly connected rotating shaft 303 to rotate. The first bearing 305 is sleeved on one end of the rotating shaft 303, and the outer side is supported and fixed by the second stabilizing frame 304 to ensure the stable rotation of the rotating shaft 303.

[0019] Furthermore, rotating plates 306 are provided on both sides of the center of the outer side wall of the rotating shaft 303. Second bearings 307 are provided on the front and rear sides of the center of one side wall of the two rotating plates 306. Connecting rods 308 are provided between the four second bearings 307. Placement racks 309 are sleeved on the outer side of the two connecting rods 308. Under the rotation of the rotating shaft 303, the two rotating plates 306 are driven to rotate synchronously with the rotating shaft 303. And through the second bearings 307, the connecting rods 308 between the four second bearings 307 can rotate relative to the rotating plates 306.

[0020] Then, each of the two placement racks 309 has a sliding groove 310 at the center of its upper end face. Multiple placement platforms 311 are slidably connected to the center of each of the two sliding grooves 310. Adjusting bolts 312 are provided on the upper sides of the front and rear ends of the multiple placement platforms 311. The two connecting rods 308 will rotate with the rotation of the rotating plate 306. The sliding groove 310 at the center of the upper end face of the placement rack 309 provides a sliding track for the placement platforms 311. The multiple placement platforms 311 can be adjusted to a suitable position as needed at the center of the sliding groove 310. The position can be adjusted at the front and rear ends by adjusting the adjusting bolts 312, which is convenient for placing welding trusses of different sizes or requiring positioning.

[0021] Furthermore, each of the two placement racks 309 has a counterweight 313 at the center of its lower end face. The counterweight 313 plays a balancing role and maintains the stability of the entire rotating structure when it rotates.

[0022] Among them, the two rotating plates 306 are provided with limiting blocks 314 at the front and rear of the center of the other side wall. The two connecting rods 308 are respectively rotatably connected to the center of the four second bearings 307. The limiting blocks 314 are used to limit the rotation angle range of the connecting rods 308, prevent the connecting rods 308 from rotating excessively, and ensure the stability and accuracy of the overall operation of the welding operation structure 3.

[0023] Secondly, the waste collection structure 4 includes a waste rack 401, which is located at the center of the lower end face of the frame 1 on one side. The waste rack 401 has a slide rail 402 at the center of both inner side walls, and a waste box 403 is located at the center of the inside of the waste rack 401. The waste rack 401 serves to support the entire waste collection structure 4.

[0024] Finally, two sliders 404 are provided at the rear center of both sides of the waste bin 403. The two sliders 404 are slidably connected to the two slide rails 402 respectively. The waste bin 403 can slide along the slide rails 402 inside the waste rack 401 through the two sliders 404. The waste generated during the welding process can be collected in the waste bin 403. When the waste bin 403 is full or needs to be cleaned, the operator can pull the waste bin 403 out or push it into the waste rack 401 along the slide rails 402 through the sliders 404 for easy waste cleaning.

[0025] When using the welding workbench of this technical solution, the first stabilizing frame 301 provides stable support for the entire structure, and the slide groove 310 of the placement frame 309 provides a linear movement track for the placement platform 311. The operator can flexibly move the placement platform 311 according to factors such as the size, shape, and welding requirements of the truss to be welded. After the placement platform 311 is moved to a suitable position, the truss to be welded is placed on the placement platform 311, and then the truss is fixed on the placement platform 311 by adjusting the adjusting bolt 312 to ensure the accuracy of the workpiece position during the welding process. After the truss is fixed, the rotating shaft 303 is driven to rotate in a circle by starting the rotator 302. The first bearing 305 and the second stabilizing frame 304 work together to ensure the stable operation of the rotating shaft 303, reduce axial and radial vibration, and ensure smooth power transmission.

[0026] As the rotating shaft 303 rotates, the two rotating plates 306 on its outer side wall move in a circular motion synchronously. The connecting rod 308 can rotate freely in its axial direction through the second bearing 307, providing multi-dimensional flexibility for the movement of the subsequent placement frame 309. The placement frame 309, which is sleeved on the outside of the connecting rod 308, can rotate on its own under the drive of the second bearing 307, making it convenient to adjust and exchange the positions of the placement platforms 311 at the front and rear, facilitating welding. Furthermore, when the rotating plate 306 rotates through the counterweight 313, the placement frame 309 maintains balanced rotation, improving the stability and accuracy of the welding operation and ensuring welding quality. At the same time, the limiting block 314 is used to limit the rotation angle range of the connecting rod 308 to prevent structural damage or component detachment due to excessive rotation, ensuring the operational reliability of the entire welding operation structure 3.

[0027] The scrap rack 401 ensures that the entire structure remains in a stable position during equipment operation. The waste generated during the welding process can be collected in the scrap bin 403. When the scrap bin 403 is full or needs to be cleaned, the operator can use the slider 404 to pull the scrap bin 403 out or push it into the scrap rack 401 along the slide rail 402 for easy waste cleaning.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
