Description

Technical Field

[0001] This application relates to the technical field of steel structure construction, and more specifically, to a butt joint device for steel structure construction. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of components such as steel beams, steel columns, and steel trusses made of sections and steel plates. At present, butt joint positioning is required between steel structure components before welding. During welding, a butt joint device is needed to position the two components. The patent document with the publication number CN117066798A in the prior art provides a steel structure welding device for building construction. This device presses and fixes the steel structure through a pressing mechanism, and pushes and adjusts the horizontal position of the movable seat through a fourth telescopic member, so that the welding ends of the two steel structures are butted at the bottom of the welding member.

[0003] Regarding the above related technology, the inventor believes that this device needs to pass the steel structure through the rotating housing and then fix it through the pressing member. However, after welding is completed, the two steel structures form an integral body, making it difficult to take them out between the two rotating housings, and it is not convenient to use. Therefore, we propose a butt joint device for steel structure construction. Utility Model Content

[0004] In order to improve the problems proposed in the above background technique, this application provides a butt joint device for steel structure construction, and adopts the following technical solutions:

[0005] A butt joint device for steel structure construction includes a bottom plate. Four support rollers are rotatably connected to the bottom plate in a rectangular structure. A support frame is fixedly connected to the bottom plate. Two connecting plates are rotatably connected to the support frame. A limiting roller is elastically connected to the connecting plate. The limiting roller cooperates with the support roller to limit the steel structure. A cross bar is slidably connected to the support frame. A pull rod is hinged between the cross bar and the connecting plate. Two mutually meshing gears are rotatably connected to the support frame. The gears are used to drive the cross bar to rise and fall, and a U-shaped plate is elastically connected to the support frame. The U-shaped plate is used to limit the cross bar.

[0006] By adopting the above technical solutions, the limiting roller and the lower two support rollers cooperate to clamp and limit the steel structure component, and both the limiting roller and the support roller can rotate, so that the clamped component can rotate to achieve welding. When the cross bar is driven to rise by rotating the gear, the cross bar and the pull rod cooperate to drive the connecting plate to rotate upward, and the limiting roller cancels the limit on the component, making it convenient to take out the welded component.

[0007] Optionally, a rotating seat is rotatably connected to the limiting roller, a plurality of sliding rods are fixedly connected to the rotating seat, the sliding rods are slidably connected to the connecting plate, and a spring A is sleeved on the sliding rods, and two ends of the spring A are respectively connected to the rotating seat and the connecting plate.

[0008] By adopting the above technical solution, when the connecting plate is perpendicular to the support frame, the spring A drives the limiting roller to elastically abut against the component, and the limiting roller can adapt to the size of the component through the telescopic adjustment of the spring A.

[0009] Optionally, a handle is fixedly connected to the gear, and a connecting rod is eccentrically connected to the gear, and one end of the connecting rod is rotatably connected to the cross bar.

[0010] By adopting the above technical solution, rotating the handle drives the gear to rotate, the two gears rotate in opposite directions, and the cross bar is driven to rise or fall through the connecting rod, so as to drive the connecting plate to flip.

[0011] Optionally, the U-shaped plate is elastically connected to the support frame through a spring B, and two ends of the U-shaped plate are in abutting fit with the cross bar.

[0012] By adopting the above technical solution, inclined surfaces are provided on the upper sides of both ends of the U-shaped plate. When the cross bar descends, it abuts against the inclined surfaces, causing the U-shaped rod to automatically give way. Subsequently, the spring B drives the U-shaped plate to reset, so that the lower end of the U-shaped plate abuts against the cross bar, causing the connecting plate to drive the limiting roller to tightly abut against the component.

[0013] Optionally, a worm is rotatably connected to the bottom plate, a handle is fixedly connected to one end of the worm, a worm gear is meshed with the worm, and the worm gear is coaxially connected and fixed to two support rollers through a coupling shaft.

[0014] By adopting the above technical solution, rotating the handle drives the worm to rotate, and the worm and the worm gear cooperate to drive the two support rollers to rotate, so that the component can be rotationally welded, improving the welding efficiency.

[0015] In summary, the present application includes at least the following beneficial technical effects:

[0016] 1. The spring A drives the limiting roller to cooperate with the two support rollers to elastically abut against the steel structure component. When the cross bar is driven to rise by rotating the gear, the connecting rod drives the connecting plate to rotate upward, so that the limiting of the component by the limiting roller is cancelled, and the component can be conveniently removed from the device. The operation is simple and the use is convenient.

[0017] 2. After the cross bar drives the limiting roller to abut against the component, the spring B drives the U-shaped plate to automatically limit the cross bar, so that the limiting roller effectively limits the component, further improving the convenience of use. Description of the Drawings

Specific embodiments

[0024] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0025] Referring to Figures 1-5 , the present application includes a bottom plate 1, on which four support rollers 2 are rotatably connected in a rectangular structure. A support frame 3 is fixedly connected to the bottom plate 1. Two connecting plates 4 are rotatably connected to the support frame 3. A limiting roller 5 is elastically connected to the connecting plate 4. The limiting roller 5 cooperates with the support rollers 2 to limit the steel structure. A cross bar 9 is slidably connected to the support frame 3. A pull rod 10 is hinged between the cross bar 9 and the connecting plate 4. Two mutually meshing gears 11 are rotatably connected to the support frame 3. The gears 11 are used to drive the cross bar 9 to rise and fall. And a U-shaped plate 13 is elastically connected to the support frame 3. The U-shaped plate 13 is used to limit the cross bar 9. The limiting roller 5 and the lower two support rollers 2 cooperate to clamp and limit the steel structure member. And both the limiting roller 5 and the support rollers 2 can rotate, so that the clamped member can be rotated to realize welding. When the cross bar 9 is driven to rise by rotating the gear 11, the cross bar 9 and the pull rod 10 cooperate to drive the connecting plate 4 to rotate upward, and the limiting roller 5 cancels the limit on the member, so that the welded member can be easily taken out.

[0026] Referring to Figure 3, a rotating seat 6 is rotatably connected to the limiting roller 5, a plurality of sliding rods 7 are fixedly connected to the rotating seat 6, the sliding rods 7 are slidably connected to the connecting plate 4, and a spring A8 is sleeved on the sliding rods 7. The two ends of the spring A8 are respectively connected to the rotating seat 6 and the connecting plate 4. When the connecting plate 4 is perpendicular to the support frame 3, the spring A8 drives the limiting roller 5 to elastically abut against the component, and the limiting roller 5 can adapt to the size of the component through the telescopic adjustment of the spring A8.

[0027] Referring to Figure 2 , a handle is fixedly connected to the gear 11, and a connecting rod 12 is eccentrically connected to the gear 11. One end of the connecting rod 12 is rotatably connected to the cross bar 9. Rotating the handle drives the gear 11 to rotate. The two gears 11 rotate in opposite directions, and drive the cross bar 9 to rise or fall through the connecting rod 12, so as to drive the connecting plate 4 to flip.

[0028] Referring to Figure 4 , the U-shaped plate 13 is elastically connected to the support frame 3 through a spring B14, and the two ends of the U-shaped plate 13 are in abutting cooperation with the cross bar 9. The upper sides of the two ends of the U-shaped plate 13 are provided with inclined surfaces. When the cross bar 9 descends, it abuts against the inclined surfaces to make the U-shaped rod 13 automatically give way, and then the spring B14 drives the U-shaped plate 13 to reset, so that the lower end of the U-shaped plate 13 abuts against the cross bar 9, so that the connecting plate 4 drives the limiting roller 5 to tightly abut against the component.

[0029] Referring to Figure 5 , a worm 15 is rotatably connected to the bottom plate 1, a handle is fixedly connected to one end of the worm 15, and a worm gear 16 is meshed with the worm 15. The worm gear 16 is coaxially connected and fixed to the two support rollers 2 through a coupling shaft. Rotating the handle drives the worm 15 to rotate, and the cooperation between the worm 15 and the worm gear 16 drives the two support rollers 2 to rotate, so that the component can be rotationally welded to improve the welding efficiency.

[0030] The implementation principle of the docking device for steel structure construction in the embodiment of the present application is as follows: Place the two components on both sides of the bottom plate 1 respectively, so that the two longitudinally arranged support rollers 2 cooperate to support the components. Then rotate the handle to drive the gear 11 to rotate. The two gears 11 rotate in opposite directions and drive the cross bar 9 to descend through the connecting rod 12. The pull rod 10 drives the connecting plate 4 to flip downward, so that the limiting roller 5 and the spring A8 cooperate to elastically abut against the component. When the U-shaped plate 13 abuts against and limits the cross bar 9, rotate the handle to drive the worm 15 to rotate, and the cooperation between the worm 15 and the worm gear 16 drives the two support rollers 2 to rotate, so that the component can be welded while rotating.
