Description

Technical Field

[0001] This utility model relates to the technical field of steel structure welding platforms, and in particular to a welding platform for building steel structures. Background Technology

[0002] With the rapid development of the construction industry, steel structures, with their advantages of high strength, light weight, and short construction cycle, are widely used in high-rise buildings, bridges, large stadiums, and other projects. Steel structures are composed of numerous welded components, and the welding quality directly affects the safety and stability of the structure. Traditional welding operations are often conducted in rudimentary environments, lacking specialized platforms, leading to difficulties in ensuring welding accuracy, low efficiency, and potential safety hazards. To address these issues and meet the demands of industrialized and standardized construction production, steel structure welding platforms have emerged and are continuously upgraded to adapt to complex and diverse welding tasks.

[0003] In the prior art, when operators use certain devices, they need devices of different sizes to perform welding operations due to the different sizes of their own working environments. However, some existing devices cannot freely adjust the size of their working area, resulting in the problem that the working area of ​​some devices is fixed and cannot fit the size of the working environment. Utility Model Content

[0004] This utility model proposes a welding platform for building steel structures, which aims to improve the problem that some existing devices cannot freely adjust the size of their working area.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A welding platform for building steel structures includes a platform plate. Two placement slots are formed inside the front and rear sides of the platform plate. Multiple outer shells are fixedly connected to the top of the platform plate. The placement slots and the outer shells are located on the same vertical plane. Multiple sliding grooves are formed on the inner wall of the platform plate. An elastic component providing elasticity is disposed inside each placement slot. The elastic component includes a hollow rod, a solid rod, and a spring. The outer side of the hollow rod is fixedly connected to the inside of the placement slot, and the outer side of the solid rod is slidably connected to the inside of the hollow rod. One end of the spring is fixedly connected to one end of the solid rod, and the other end of the spring is fixedly connected to the inside of the hollow rod. A retaining ball is fixedly connected to the other end of the hollow rod. An L-shaped wedge is fixedly connected to the outer side of the retaining ball. A pressing rod is slidably connected to the inner wall of the outer shell. A trapezoidal block is fixedly connected to the bottom of the pressing rod. A second spring is sleeved on the outer side of the pressing rod. One end of the second spring is fixedly connected to the inside of the outer shell, and the other end of the second spring is fixedly connected to the outside of the trapezoidal block.

[0007] The above technical solution features a tabletop with a placement groove and a housing. In conjunction with a spring assembly, the pressing rod can control the ball clamping via a trapezoidal block, facilitating the fixing or adjustment of the steel structure and improving the stability and ease of operation during welding.

[0008] As a further description of the above technical solution:

[0009] The platform has multiple sets of bolts on its external threaded connection, and each set of bolts is connected to a protective shell on its external threaded connection. The inner wall of the protective shell has a slot.

[0010] The above technical solution includes a platform threaded connection bolt and a protective shell. The protective shell has a slot to protect the bolt, and the slot can be used with other components to enhance the diversity and stability of the structural connection.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the platform is rotatably connected to two rotating shafts, and an extension plate is fixedly connected to the outside of the rotating shafts.

[0013] The above technical solution uses a rotating platform connected to a rotating shaft and an extension plate, which allows for flexible adjustment of the platform area according to welding requirements, increasing the working area and adapting to welding steel structures of different sizes.

[0014] As a further description of the above technical solution:

[0015] The extension plate has two gears fixedly connected to its exterior, and the inner wall of the platform has two rotating shafts rotatably connected to its interior. The rotating shafts are fixedly connected to the exterior of half gears.

[0016] The above technical solution uses a gear to connect the extended plate, and the platform is equipped with a rotating shaft and a half gear. The gear structure enables the extended plate to rotate smoothly and be precisely positioned, making operation more convenient.

[0017] As a further description of the above technical solution:

[0018] An L-shaped connecting plate is fixedly connected to the outside of the second rotating shaft, and two fixing blocks are fixedly connected to the bottom of the platform. The other end of the L-shaped connecting plate away from the second rotating shaft is slidably connected inside the first slot.

[0019] The above technical solution involves connecting the rotating shaft two to an L-shaped connecting plate, which can cooperate with the protective shell slot one to maintain structural stability when adjusting the extension plate and ensure the reliability of the welding platform under different conditions.

[0020] As a further description of the above technical solution:

[0021] The inner wall of the second fixing block is provided with a slot 2, and the inner wall of the second fixing block is provided with a storage groove.

[0022] The above technical solution provides a second slot and a storage slot for the fixing block, which provides space for the storage and installation of the feet and related components, optimizes the structural layout, and facilitates transportation and storage.

[0023] As a further description of the above technical solution:

[0024] The storage slot is internally fixedly connected to two fixing blocks, and a rotating shaft is passed through and connected to the inner wall of the fixing block and the inner walls of the two fixing blocks.

[0025] The above technical solution uses a rotating shaft three in conjunction with the first and second fixing blocks inside the storage slot to allow the base to rotate flexibly, making it easy for the platform to be unfolded for use or stored, thus improving space utilization.

[0026] As a further description of the above technical solution:

[0027] The rotating shaft three is externally fixedly connected to a foot, and multiple feet are located on the same horizontal plane.

[0028] The above technical solution has the base installed on the rotating shaft three and located on the same horizontal plane, providing stable support for the welding platform, ensuring stability when used in different sites, and facilitating welding operations.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the operator moves multiple L-shaped connecting plates upwards. As the L-shaped connecting plates move upwards, they enter the space formed between two retaining balls through the slot. When the two retaining balls contact the L-shaped connecting plates, the solid rod slides inside the hollow rod under the elastic force provided by the spring, causing the retaining balls to clamp the L-shaped connecting plates. Simultaneously, the two L-shaped inclined blocks move in opposite directions, causing the trapezoidal block to be lifted upwards. Therefore, the two extended plates can move upwards and unfold, expanding the working area of ​​the device. Then, the operator rotates the base downwards via the rotating shaft to support the device. This structure allows the operator to freely adjust the size of the working area of ​​the device, solving the problem that the working area of ​​some devices is fixed and cannot fit the size of the working environment.

[0031] 2. In this invention, the operator rotates the base downwards via the rotating shaft to support the device, and simultaneously the two L-shaped inclined blocks move in opposite directions, causing the trapezoidal block to be lifted upwards. This allows the two extended plates to move upwards and unfold. This structure achieves a foldable device, solving the problem of some devices being inconvenient to transport and assemble due to their inability to fold. Attached Figure Description

[0041] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Reference Figures 1 to 7This utility model provides an embodiment of a welding platform for a building steel structure, including a platform 1, which serves as the basic load-bearing component of the welding platform and provides a stable support surface for the entire device. Two placement slots 2 are provided on both the front and rear sides of the platform 1 to house elastic components, providing a fixed space for hollow rods 5. The elastic components enable elastic fixation and adjustment of related components, meeting the workpiece fixation requirements of different welding operations. Multiple outer shells 3 are fixedly connected to the top of the platform 1, protecting internal components such as pressing rods 10 and springs 12, while also providing sliding tracks for the pressing rods 10 to ensure smooth pressing operations. The multiple placement slots 2 and multiple outer shells 3 are located on the same vertical plane. Multiple sliding grooves 4 are provided on the inner wall of the platform 1, cooperating with other movable components, such as providing movement paths for related connecting parts during the unfolding or retraction of the extension plate 17, ensuring the flexibility of platform structure adjustment. The placement slots 2 are equipped with elastic components that provide elasticity. Each elastic component includes a hollow rod 5, one end fixed inside the placement slot 2, and the other end connected to a retaining ball 8. Solid rod 6 and spring 7 provide continuous elasticity to solid rod 6, ensuring that the clamping ball 8 maintains a constant pressure on the workpiece, preventing workpiece displacement during welding and ensuring welding accuracy. Hollow rod 5 is externally fixedly connected to the inside of placement groove 2, and solid rod 6 is externally slidably connected to the inside of hollow rod 5. One end of spring 7 is fixedly connected to one end of solid rod 6, and the other end of spring 7 is fixedly connected to the inside of hollow rod 5. The other end of hollow rod 5 is fixedly connected to clamping ball 8, and L-shaped inclined block 9 is fixedly connected to the outside of clamping ball 8. Pressing rod 10 is slidably connected to the inner wall of outer shell 3, and trapezoidal block 11 is fixedly connected to the bottom of pressing rod 10. Spring 12 is sleeved on the outside of pressing rod 10, providing upward restoring force so that pressing rod 10 can automatically return to its initial position after operation, facilitating the next operation. One end of spring 12 is fixedly connected to the inside of the outer casing 3, and the other end of spring 12 is fixedly connected to the outside of the trapezoidal block 11;

[0043] The platform 1 has multiple sets of bolts 13 externally threadedly connected to it. Each set of bolts 13 is externally threaded with a protective shell 14. The inner wall of the protective shell 14 has a slot 15. Two rotating shafts 16 are rotatably connected to the inner wall of the platform 1. An extension plate 17 is fixedly connected to the outer side of each rotating shaft 16, and is connected to the platform 1 via the rotating shafts 16. This extension plate can be unfolded when needed to increase the working area of ​​the platform, meeting the welding requirements of large workpieces; it also saves space when stored. Two gears 18 are fixedly connected to the outer side of the extension plate 17. Two rotating shafts 19 are rotatably connected to the inner wall of the platform 1. Half gears 20 are fixedly connected to the outer side of each rotating shaft 19, meshing with the gears 18. This converts the rotation of the rotating shafts 19 into the rotational power of the extension plate 17, ensuring the smoothness and accuracy of the extension plate 17's rotation. An L-shaped connecting plate 21 is fixedly connected to the outside of the rotating shaft 19. Two fixing blocks 27 are fixedly connected to the bottom of the platform 1, providing support for the L-shaped connecting plate 21. At the same time, the internal slots 22 and storage slots 23 are used for storing and positioning the feet 26, which are important supporting components for the stability of the platform structure. The other end of the L-shaped connecting plate 21, away from the rotating shaft 19, is slidably connected to the inside of the slot 15.

[0044] The inner wall of fixing block 27 has a slot 22 and a storage groove 23. Two fixing blocks 24 are fixedly connected inside the storage groove 23. A rotating shaft 25 is passed through and connected to the inner walls of fixing block 27 and the two fixing blocks 24, serving as the rotation center of the foot 26, allowing the foot 26 to rotate around it, thus enabling the foot 26 to unfold as a support platform or be stored to save space. The foot 26 is fixedly connected to the outside of the rotating shaft 25, and multiple feet 26 are located on the same horizontal plane.

[0045] Working principle: The platform is initially in an unfolded state. When the operator needs to perform welding operations in a small space, they first press down on a set of pressing rods 10, which drives the trapezoidal block 11 to move vertically downwards until it is stuck in the space formed by the two L-shaped inclined blocks 9. When the trapezoidal block 11 moves vertically downwards, it generates a squeezing force. Under the action of the solid rod 6 and the spring 7, the outer part of the solid rod 6 slides inside the hollow rod 5. Therefore, the two solid rods 6 and the two locking balls 8 move in opposite directions, making the space in the middle of the two L-shaped inclined blocks 9 larger. So the trapezoidal block 11 can smoothly enter the space formed between the two L-shaped inclined blocks 9.

[0046] When the two ball bearings 8 move in opposite directions, the L-shaped connecting plate 21, which was originally stuck in the middle of the two ball bearings 8, is released. Under its own gravity, the L-shaped connecting plate 21 begins to fall and rotate, causing the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 causes the half gear 20 to rotate. Since the half gear 20 and the gear 18 mesh with each other, the rotation of the half gear 20 causes the gear 18 to rotate, thereby causing the rotating shaft 16 and the extension plate 17 to rotate together. Therefore, the extension plate 17 can rotate downward, reducing the area of ​​the welding platform for use in a smaller working environment.

[0047] When the working area of ​​the device needs to be expanded, the operator rotates multiple L-shaped connecting plates 21 upwards, allowing them to enter the space formed between two retaining balls 8 through the slot 15. When the two retaining balls 8 contact the L-shaped connecting plates 21, the solid rod 6 slides inside the hollow rod 5 under the elastic contraction provided by the spring 7, causing the retaining balls 8 to clamp the L-shaped connecting plates 21. At the same time, the two L-shaped inclined blocks 9 also move in opposite directions, causing the trapezoidal block 11 to be pushed upwards. Thus, the two extension plates 17 can rotate upwards and unfold, expanding the working area of ​​the device. The operator rotates the base 26 downwards around the rotating shaft 25 to support the device. When not in use, the base 26 is reversed to store the device, reducing the usable space.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
