Description

Technical Field

[0001] This utility model relates to the field of steel truss installation technology, specifically a steel truss positioning structure. Background Technology

[0002] A truss made of steel bars as the top chord, bottom chord, and web members, connected by resistance spot welding, is called a steel truss. A composite load-bearing slab that is connected to the base plate by resistance spot welding is called a steel truss floor deck.

[0003] When combining steel trusses with the base plate, some methods involve directly placing the steel trusses on the base plate for welding. This can easily cause displacement between the steel trusses and the base plate, resulting in inaccurate welding. Other methods use positioning devices to place multiple steel trusses at preset intervals. However, this requires manual pressing of the steel trusses to ensure they are tightly attached to the base plate, thereby enhancing the welding effect. This process is relatively complex and makes it inconvenient to move the steel trusses. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel truss positioning structure that can position and press the steel truss to prevent it from slipping during welding to the base plate.

[0005] This utility model provides the following technical solution: a steel truss positioning structure, including a rectangular frame, with several rollers rotatably connected to the upper part of the rectangular frame, and a sliding groove 1 and a sliding groove 2 respectively opened on both sides of the rectangular frame. A threaded rod 1 is rotatably connected in the sliding groove 1, and a sliding rod is fixedly connected in the sliding groove 2. A U-shaped plate 1 is fixedly connected to the front end of the upper surface of the rectangular frame, and a U-shaped plate 2 is threadedly connected to the threaded rod 1. The U-shaped plate 2 is slidably connected to the sliding rod. A pressing mechanism 1 is installed on the U-shaped plate 1, and a pressing mechanism 2 is installed on the U-shaped plate 2. A fixed seat is fixedly connected to both the pressing mechanism 1 and the pressing mechanism 2. A driving mechanism for driving the threaded rod 1 to rotate is fixedly connected to the side of the rectangular frame.

[0006] Furthermore, the extrusion mechanism includes a driver fixedly connected to a U-shaped plate, a bidirectional threaded rod two fixedly connected to the output end of the driver, a slider one and a slider two threadedly connected to both sides of the bidirectional threaded rod two, a fixed block fixedly connected to the middle position of the U-shaped plate, the lower surfaces of slider one, slider two and the fixed block being flush with each other, and a hydraulic cylinder fixedly connected to the lower ends of slider one, slider two and the fixed block.

[0007] Furthermore, the structure of the second extrusion mechanism is the same as that of the first extrusion mechanism.

[0008] Furthermore, the fixing base includes a pressing block fixedly connected to the lower end of the three hydraulic cylinders, and the lower surface of the pressing block is provided with a slot.

[0009] Furthermore, the driving mechanism includes a second driver fixedly connected to the side of the rectangular frame. The output end of the second driver is fixedly connected to a rotating shaft. The front end of the rotating shaft is fixedly connected to a first pulley. The front end of the first threaded rod is fixedly connected to a second pulley. A rubber belt connects the first pulley and the second pulley together.

[0010] Furthermore, both the second driver and the first driver are reversible motors.

[0011] Furthermore, both the first U-shaped plate and the second U-shaped plate are equipped with scales.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This type of steel truss positioning structure allows the base plate to be placed on a roller when welding the steel truss to the base plate. The steel truss is then placed on the base plate and its position is adjusted so that the upper chord is directly below the fixing seat. This allows multiple steel trusses to be positioned and pressed simultaneously, thus firmly attaching the steel truss to the base plate. During the welding process, it is not easy to slip, and it also facilitates the quick transfer of the welded product. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 A steel truss positioning structure includes a rectangular frame 1. Several rollers 2 are rotatably connected to the upper part of the rectangular frame 1. A first groove 3 and a second groove 4 are respectively opened on both sides of the rectangular frame 1. A threaded rod 5 is rotatably connected in the first groove 3, and a sliding rod 6 is fixedly connected in the second groove 4. A U-shaped plate 7 is fixedly connected to the front end of the upper surface of the rectangular frame 1. A second U-shaped plate 8 is threadedly connected to the threaded rod 5. The second U-shaped plate 8 is slidably connected to the sliding rod 6. A first extrusion mechanism is installed on the first U-shaped plate 7, and a second extrusion mechanism is installed on the second U-shaped plate 8. A fixed seat is fixedly connected to both the first and second extrusion mechanisms. A drive mechanism for driving the threaded rod 5 to rotate is fixedly connected to the side of the rectangular frame 1.

[0021] like Figures 1 to 4 As shown, in use, the steel truss positioning structure of this utility model involves first placing the base plate on the roller 2 and pushing it inward so that the front end of the base plate is below the U-shaped plate 7. Then, the steel truss is placed on the base plate. The position of the U-shaped plate 8 is adjusted through the drive mechanism so that the base plate is below the U-shaped plate 8. The height of the fixed seats on the extrusion mechanism 1 and extrusion mechanism 2 is adjusted to bring the fixed seats closer to the upper chord of the steel truss. The position of the steel truss is then moved appropriately so that the upper chord of the steel truss is directly below the fixed seat. The position of the fixed seat is then adjusted further so that it presses down on the upper chord of the steel truss, thus fixing the position of the steel truss. This prevents the steel truss and the base plate from slipping when welding, facilitating welding and ensuring welding quality. After welding, the fixed seat is moved upward to release the pressure on the steel truss, allowing for quick movement of the steel truss and the base plate for the next welding operation.

[0022] like Figure 1 As shown, the extrusion mechanism includes a driver 9 fixedly connected to a U-shaped plate 7. The output end of the driver 9 is fixedly connected to a bidirectional threaded rod 10. The two sides of the bidirectional threaded rod 10 are threadedly connected to sliders 11 and 12. A fixing block 13 is fixedly connected to the middle position of the U-shaped plate 7. The lower surfaces of sliders 11, 12 and 13 are flush with each other, and the lower ends of sliders 11, 12 and 13 are all fixedly connected to hydraulic cylinders 14.

[0023] Specifically, the base plate is placed on roller 2 and pushed inward so that the front end of the base plate is below U-shaped plate 7. The steel truss is then placed on the base plate. The position of U-shaped plate 8 is adjusted by the drive mechanism so that the base plate is below U-shaped plate 8. The driver 9 is activated, which causes the bidirectional threaded rod 10 to rotate, causing sliders 11 and 12 to move in opposite directions, thereby adjusting their positions. The hydraulic cylinder 14 is then activated, pushing the fixed seat downward so that it moves downward and is close to the upper chord of the steel truss. The position of the steel truss is then adjusted so that the upper chord is directly below the fixed seat. The fixed seat continues to move downward, pressing the upper chord of the steel truss firmly onto the base plate, thus positioning the steel truss and facilitating welding to the base plate.

[0024] like Figure 1 As shown, the structure of the second extrusion mechanism is the same as that of the first extrusion mechanism.

[0025] Specifically, the second extrusion mechanism and the first extrusion mechanism simultaneously press down on both ends of the upper chord of the steel truss to position and fix the steel truss without affecting the welding process.

[0026] like Figure 3 As shown, the fixed base includes a pressing block 15 fixedly connected to the lower end of three hydraulic cylinders 14, and a slot 16 is provided on the lower surface of the pressing block 15.

[0027] Specifically, the cross-section of the slot 16 is an isosceles triangle, which can press the upper chord of steel trusses of different sizes. At the same time, it limits the left and right movement of the upper chord, making it difficult for it to move left and right.

[0028] like Figure 4 As shown, the driving mechanism includes a second driver 17 fixedly connected to the side of the rectangular frame 1. The output end of the second driver 17 is fixedly connected to a rotating shaft 18. The front end of the rotating shaft 18 is fixedly connected to a pulley 19. The front end of the threaded rod 5 is fixedly connected to a second pulley 20. A rubber belt 21 is connected between the first pulley 19 and the second pulley 20.

[0029] Specifically, starting the second driver 17 causes the rotating shaft 18 and the pulley 19 to rotate, which in turn drives the pulley 20 to rotate via the rubber belt 21, causing the threaded rod 5 to rotate. This causes the U-shaped plate 8 to move along the direction of the threaded rod 5 and the sliding rod 6, so that the base plate and the steel truss are located below the U-shaped plate 8. The pressing mechanism 2 can then be used to position and press the end of the steel truss to fix it.

[0030] like Figure 1As shown, both the second driver 17 and the first driver 9 are forward and reverse rotating motors.

[0031] Specifically, this allows control of the forward or reverse rotation of threaded rod 5 and bidirectional threaded rod 10, thereby facilitating the adjustment of the position of U-shaped plate 8, as well as the positions of slider 11 and slider 12.

[0032] like Figure 1 As shown, both the U-shaped plate 7 and the U-shaped plate 8 are equipped with a scale 22.

[0033] Specifically, the distance between the three fixed seats can be easily determined by using the scale 22, thereby determining the spacing between the three steel trusses.

[0034] Although the present invention 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 invention should be included within the protection scope of the present invention.
