Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a support for steel structure welding. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, and employs rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The various components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields.

[0003] Traditional steel structure supports typically rely on bolt fixing or manual wrench adjustment for angle adjustment, requiring repeated disassembly and manual calibration, which has several shortcomings in practical use. For example, angle adjustment efficiency is low. In the welding of steel trusses in large stadiums, workers must use wrenches to loosen the bolts fixing the supports one by one, requiring the disassembly and reassembly of multiple bolts for a single adjustment, a time-consuming and labor-intensive process. Furthermore, when manually calibrating angles, the lack of precise measuring tools often necessitates multiple fine adjustments to achieve the target angle, each requiring retightening of the bolts, significantly slowing down the construction progress. In addition, traditional supports are also inadequate for welding irregularly shaped steel components that require frequent angle changes, failing to respond quickly to adjustment needs. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that traditional steel structure supports are usually fixed with bolts or adjusted with manual wrenches, which requires repeated disassembly and manual calibration, resulting in many shortcomings in actual use.

[0005] To solve the above technical problems, this application provides a support for welding steel structures, including a base. A rotating shaft is rotatably mounted on the middle of the upper end of the base. A base plate is fixedly mounted on the upper end of the base. A worm gear is fixedly mounted on the outer side of the middle of the rotating shaft. A support is fixedly mounted on one side of the middle of the upper end of the base. An upper sleeve is fixedly mounted on the upper side of one side of the support. A lower sleeve is fixedly mounted on the middle of the lower end of one side of the support. Two fixing plates are provided on one side of the support. An upper sleeve is fixedly mounted on the middle of the fixing plates. A worm gear is rotatably mounted on the middle of one end of the two fixing plates. A handwheel is fixedly mounted on one end of the worm gear. A connecting rod is fixedly mounted on the middle of the other end of the two fixing plates. An upper connecting rod is sleeved on the surface of the connecting rod. A lower connecting rod is rotatably connected to one end of the upper connecting rod. One end of the lower connecting rod is sleeved on the surface of the middle of the lower sleeve. A pedal is fixedly mounted on one side of the lower connecting rod. A strong spring is fixedly connected to the lower end of the pedal.

[0006] In some embodiments, the upper middle portion of the base plate is provided with sliding grooves on both sides, a guide rod is fixedly installed in the middle of one of the sliding grooves, and a two-way lead screw is rotatably installed in the middle of the other sliding groove. Clamping plates are slidably engaged on both sides of the upper middle portion of the base plate, and sliders are fixedly installed at the lower ends of the two clamping plates.

[0007] In some embodiments, the two sets of sliders are respectively slidably engaged in the middle of the slide groove, the slider is slidably engaged in the middle of two sliders located on the same side, the bidirectional lead screw is threadedly connected to the middle of two sliders located on the other side, a motor is fixedly installed on one side of the middle of one end of the base plate, and the output end of the motor is fixedly connected to one end of the bidirectional lead screw.

[0008] In some embodiments, handles are fixedly installed at the middle of both ends of the base plate, and multiple rubber hoses are fixedly installed on the surface of both clamps.

[0009] In some embodiments, the worm and the worm wheel mesh with each other, and the fixing rods in the middle of the two fixing plates are rotatably mounted in the middle of the upper sleeve on one side of the bracket.

[0010] In some embodiments, one end of the powerful spring is fixedly connected to the upper end of the base.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. When in use, this utility model can achieve large-angle adjustment and precise fine-tuning of the steel structure workpiece to be welded. The dual-mode angle adjustment makes the device more flexible and efficient. The worm gear driven by the handwheel achieves precise fine-tuning of the angle to meet the requirements of high-precision welding. After stepping on the pedal to release the limit, the handle can be directly moved to achieve large-angle adjustment, taking into account both fine-tuning and rapid repositioning, and adapting to a variety of welding scenarios.

[0013] 2. When in use, this utility model can quickly clamp the steel structure workpiece to be welded. The motor drives the bidirectional lead screw to automatically adjust the clamping plate spacing, quickly adapt to different specifications of components and self-lock and fix them. The rubber hose wraps the clamping surface, which not only prevents damage to the surface of the component, but also absorbs vibration and buffers thermal stress, ensuring welding quality and component integrity.

[0019] 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.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a support for welding steel structures, including a base 1, a rotating shaft 11 rotatably mounted at the middle of the upper end of the base 1, a base plate 2 fixedly mounted at the upper end of the base 1, a worm gear 12 fixedly mounted on the outer side of the middle of the rotating shaft 11, a support 13 fixedly mounted on one side of the middle of the upper end of the base 1, an upper sleeve 14 fixedly mounted on the upper side of one side of the support 13, a lower sleeve 15 fixedly mounted at the middle of the lower end of one side of the support 13, two fixing plates 16 provided on one side of the support 13, an upper sleeve 14 fixedly mounted in the middle of the fixing plate 16, and a worm gear 23 rotatably mounted at the middle of one end of the two fixing plates 16. A handwheel 24 is fixedly installed at one end of the worm gear 23. A connecting rod 18 is fixedly installed at the middle of the other end of the two fixed plates 16. An upper connecting rod 19 is sleeved on the surface of the connecting rod 18. A lower connecting rod 20 is rotatably connected to one end of the upper connecting rod 19. One end of the lower connecting rod 20 is sleeved on the surface of the middle part of the lower sleeve 15. A pedal 21 is fixedly installed on one side of the lower connecting rod 20. A strong spring 22 is fixedly connected to the lower end of the pedal 21. The worm gear 23 and the worm wheel 12 mesh with each other. A fixed rod 17 in the middle of the two fixed plates 16 is rotatably installed in the middle of the upper sleeve 14 on one side of the bracket 13. One end of the strong spring 22 is fixedly connected to the upper end of the base 1.

[0021] In this embodiment, the handwheel 24 drives the worm gear 23 to mesh with the worm wheel 12, which can drive the rotating shaft 11, the base plate 2, and the upper structure to rotate smoothly. This allows for precise fine-tuning of the angle of the workpiece fixed on the base plate 2, improving construction efficiency. Simultaneously, utilizing the self-locking characteristic of the worm gear 23 transmission between the worm wheels 12, the workpiece can be automatically locked after adjustment to the target angle, preventing displacement due to vibration or other factors during welding and ensuring positioning accuracy. The operator can also step on the pedal 21 to compress the powerful spring 22. The pedal 21 is connected to the two fixed plates via the lower connecting rod 20 and the upper connecting rod 19. The 16-linkage mechanism allows the pedal 21 to quickly tension or release the powerful spring 22. This, in turn, pulls the connecting rod 18 at one end of the two fixed plates 16 along the fixed rod 17 in the middle of the upper sleeve 14 via the lower connecting rod 20 and the upper connecting rod 19. This causes the worm gear 23 installed at the ends of the two fixed plates 16 to disengage from the worm wheel 12, thus removing the worm gear 23's constraint on the worm wheel 12. At this point, the operator can directly adjust the angle of the fixed workpiece above the base plate 2 by moving the base plate 2. This allows for a significant adjustment of the angle of the base plate 2 and the fixed workpiece above it, making the device more practical.

[0022] Example 2: As Figure 1 , Figure 4 As shown, the upper middle part of the base plate 2 has two sliding grooves 27 on both sides. A guide rod 30 is fixedly installed in the middle of one of the sliding grooves 27, and a double-acting screw 29 is rotatably installed in the middle of the other sliding groove 27. The upper middle part of the base plate 2 has two sliding clamps 25 on both sides. The lower ends of the two clamps 25 are fixedly installed with sliders 28. The two sets of sliders 28 are respectively slidably clamped in the middle of the sliding grooves 27. The sliders 28 are slidably clamped in the middle of the two sliders 28 on the same side. The double-acting screw 29 is threadedly connected to the middle of the two sliders 28 on the other side. A motor 31 is fixedly installed on one side of the middle of one end of the base plate 2. The output end of the motor 31 is fixedly connected to one end of the double-acting screw 29. Handles 32 are fixedly installed in the middle of both ends of the base plate 2. Multiple rubber hoses 26 are fixedly installed on the surface of the two clamps 25.

[0023] In this embodiment, the two clamping plates 25 are respectively slidably engaged in the grooves 27 opened above the base plate 2 via the two sliders 28 below. The bidirectional lead screw 29 is driven to rotate by the motor 31. The bidirectional lead screw 29 synchronously drives the clamping plates 25 on both sides to move towards or away from each other, which can quickly adapt to steel structure components of different widths and improve clamping efficiency. The lead screw drive has a self-locking function, so there is no risk of loosening of the components during welding, ensuring positioning accuracy. The guide rod 30 cooperates with the groove 27 to guide and ensure that the clamping plates 25 do not deviate during translation. The rubber hose 26 conforms to different cross-sectional shapes through elastic deformation, avoiding damage to the surface of the components by rigid clamping. The rubber hose 26 can absorb the small vibrations during the welding process and reduce the stress concentration caused by thermal deformation of the components. At the same time, it avoids scratches caused by direct metal contact and improves the surface quality of the finished product. The handle 32 allows the user to quickly rotate the base plate 2, the upper structure, and the clamped workpiece by using the handle 32 when the worm 23 disengages from the worm wheel 12.

[0024] like Figures 1-4 As shown, during use, the steel structure workpiece to be welded is placed above the base plate 2. Then, the motor 31 is started to drive the bidirectional lead screw 29 to rotate. The two side clamping plates 25 slide along the slide groove 27 via the lower slider 28, achieving opposite or opposite movement, which can quickly clamp the steel structure component. At the same time, the guide rod 30 cooperates with the slide groove 27 to guide, ensuring that the clamping plate 25 moves without deviation. The self-locking function of the lead screw prevents the component from loosening during welding. The rubber hose 26 on the surface of the clamping plate 25 fits the cross section of the component through elastic deformation, which can not only avoid surface damage from rigid clamping, but also absorb welding vibration. When the angle needs to be adjusted, the handwheel 24 is turned to drive the worm gear 23 to rotate. The worm gear 23 meshes with the worm wheel 12, and the worm gear 23 can drive the rotating shaft 11 and the base plate 2 fixed on it to rotate smoothly, so as to achieve precise adjustment of the workpiece angle. Utilizing the self-locking characteristics of the worm wheel 12 and worm gear 23, it will automatically lock after adjustment to the target angle to prevent displacement during welding and ensure positioning accuracy. When a significant adjustment of the welding angle is required, simply step on pedal 21 to compress the powerful spring 22. Pedal 21, through lower connecting rod 20 and upper connecting rod 19, links two fixed plates 16, pulling the connecting rod 18 to rotate around the fixed rod 17 inside the upper sleeve 14, causing the worm 23 to disengage from the worm wheel 12. At this point, the limit is removed, and the operator can directly use handle 32 to move the base plate 2 to quickly adjust the workpiece to the required large angle. After adjustment, release pedal 21, and the spring will return to its original position, causing the worm 23 to re-engage and lock with the worm wheel 12.
