Description

Technical Field

[0001] This utility model relates to the technical field of steel structures, and in particular to a self-balancing support device for steel structure lap joint columns. Background Technology

[0002] Steel structures, primarily constructed of steel, are one of the main types of building structures. Steel structure lap columns refer to columns connected by lap joints in steel structure buildings to enhance the overall stability and load-bearing capacity of the structure. This connection method is typically used between columns to transfer loads and moments, ensuring the stability of the steel structure. During the construction of a steel structure, temporary supports are needed for the lap columns to facilitate welding and fixing at the beam connections. Existing technology publication number CN214996335 proposes a support device for steel structure construction, including a support column, a lifting column, a support plate, a limiting side plate, a stabilizing base plate, a lead screw, a rotating shaft, a driven bevel gear, and a driving bevel gear. Positioning rods are symmetrically installed on the left and right sides and the front and rear sides of the lower end face of the stabilizing base plate. A support column is welded to the middle position of the upper end face of the stabilizing base plate. A lead screw is installed in the middle position inside the support column. A driven bevel gear is welded to the lower side of the annular side of the lead screw. A rotating shaft is engaged in the middle position of the left end face of the driving bevel gear. A lifting column meshes with the annular side of the lead screw. A support plate is welded to the upper end face of the lifting column. However, it cannot be balanced, and if it tilts or collapses, it could cause serious economic and personal damage. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a self-balancing support device for steel structure lap columns that is easy to adjust in height, improves convenience, can be balanced to avoid tilting, and ensures safety.

[0004] This utility model discloses a self-balancing support device for steel structure lap columns, comprising a base, a lifting plate, a movable support component, a lifting component, a balance adjustment component, and a clamping component. Movable support components are installed on the left and right sides of the base, and a lifting component is installed at the center of the top of the base. A lifting plate is installed at the top of the lifting component via the balance adjustment component, and a clamping component is installed at the top of the lifting plate. The lap column is placed on top of the lifting plate and clamped by the clamping component. The movable support component moves the lap column to the construction position, ensuring stability during construction. The lifting component lifts the lap column to the usable height for easy height adjustment and improved convenience. The balance adjustment component allows for balance adjustment to prevent tilting and ensure safety.

[0005] Preferably, the movable support component includes multiple movable wheels, two electric telescopic rods, two support base plates, two sets of I-beam guide rods, and two connecting plates. The multiple movable wheels are respectively installed at the four corners of the base bottom. The two electric telescopic rods are symmetrically installed on the left and right sides of the base. Support base plates are installed at the telescopic ends of the electric telescopic rods. I-beam guide rods slide symmetrically on the left and right sides of the base about the electric telescopic rods. The bottom ends of the I-beam guide rods are connected to the top ends of the support base plates, and connecting plates are connected to the top ends of the I-beam guide rods. The connecting plates have clearance holes in the middle that match the electric telescopic rods. The multiple movable wheels allow the overlapping column to be moved to the usage position, improving flexibility during use. Activating the electric telescopic rods causes the support base plates to contact the ground downwards, detaching the electric telescopic rods from the ground, increasing friction and preventing movement during use. When the support base plates move, they cause the I-beam guide rods to slide on the base, providing support and guidance, improving structural strength and ensuring stability.

[0006] Preferably, the lifting component includes a first gearbox, a lifting motor, a threaded column, a lifting column, a mounting plate, and a guide assembly. A mounting groove is provided in the center of the bottom of the base. The first gearbox is installed in the mounting groove, and its input end is connected to the output end of the lifting motor. The output end of the first gearbox passes through the top of the base and is fitted with a threaded column. The lifting column is screwed onto the outer wall of the threaded column, and a mounting plate is installed on the top of the lifting column. Starting the lifting motor drives the threaded column to rotate via the first gearbox, pushing the lifting column to adjust the height of the lifting plate, thus lifting the overlapping column upwards to the usable height, facilitating height adjustment and improving convenience.

[0007] Preferably, the guide assembly includes multiple support slide rods, multiple connecting columns, and multiple support sleeves. The multiple support slide rods are axially mounted on the top of the base about the lifting column. Multiple connecting columns are axially mounted on the outer wall of the lifting column. Support sleeves are mounted on the outer wall of the connecting columns and are slidably mounted on the outer wall of the support slide rods. The top of the support sleeves is connected to the bottom of the mounting plate. When the lifting column moves the mounting plate, the mounting plate moves the support sleeves on the support slide rods. The support sleeves and connecting columns limit and guide the lifting column, improving structural strength and ensuring stability during lifting.

[0008] Preferably, the balance adjustment component includes a rotating seat, a rotating block, a support seat, a rotating shaft, a connecting seat, a second electric telescopic rod, and a detection component. The support seat is installed on the top of the mounting plate, and a rotating block is rotatably mounted on the support seat via the rotating shaft. The top of the rotating block is connected to the bottom of the lifting plate. A connecting seat is rotatably mounted on the left side of the mounting plate, and a second electric telescopic rod is mounted on the connecting seat. The other end of the second electric telescopic rod is rotatably connected to the bottom of the lifting plate via the rotating seat. Activating the extension and retraction of the second electric telescopic rod can push the lifting plate to drive the rotating block to rotate on the support seat, adjust the angle of the lifting plate, perform balance adjustment, prevent tilting, and ensure safety.

[0009] Preferably, the detection components include a tilt sensor and a level. The tilt sensor is installed on the bottom right side of the lifting platform, and the level is installed in the middle of the front end of the lifting platform. The tilt sensor detects the tilt angle of the lifting platform in real time. If tilting occurs and the support is unsafe, an alarm is triggered immediately. At the same time, the level allows the staff to intuitively detect the level status of the lifting platform, improving its practicality.

[0010] Preferably, the clamping component includes a rotating rod, a second gearbox, a clamping motor, a clamping slider, two clamping plates, and two sets of mounting sliders. A clamping groove is formed at the center of the top of the lifting plate. The rotating rod is rotatably installed within the clamping groove. The rear input end of the rotating rod is connected to the output end of the second gearbox, and the input end of the second gearbox is connected to the output end of the clamping motor. Threaded grooves are symmetrically formed at both ends of the rotating rod. Two clamping sliders are symmetrically slidably installed within the clamping grooves and screwed onto the rotating rod. A clamping plate is installed on the top of the clamping sliders. Guide mounting grooves are symmetrically formed on the left and right sides of the top of the lifting plate. Mounting sliders are symmetrically installed on the left and right sides of the bottom of the clamping plates and slidably installed within the guide mounting grooves. After the overlapping column is placed on the top of the lifting plate, the clamping motor is started, driving the rotating rod to rotate via the second gearbox. The rotating rod moves on the top of the lifting plate via the clamping sliders, clamping and fixing the overlapping column to prevent slippage. When the clamping plates move, they drive the mounting sliders to slide within the guide mounting grooves, guiding and limiting them, enhancing connection strength, and ensuring stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the overlapping column is placed on the top of the lifting plate and clamped by the clamping component. The overlapping column is moved to the construction position by the moving support component, ensuring stability during construction. The overlapping column is lifted to the working height by the lifting component, which facilitates height adjustment and improves convenience. The balance adjustment component can be used for balance adjustment to avoid tilting and ensure safety. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5As shown, multiple movable wheels 2 are respectively installed at the four corners of the bottom of the base 1. Two electric telescopic rods 3 are symmetrically installed on the left and right sides of the base 1. A support base plate 4 is installed at the telescopic end of the electric telescopic rod 3. I-beam guide rods 5 are symmetrically slidable on the left and right sides of the base 1 about the electric telescopic rod 3. The bottom end of the I-beam guide rod 5 is connected to the top end of the support base plate 4. A connecting plate 6 is connected to the top end of the I-beam guide rod 5. The connecting plate 6 has a clearance hole in the middle that matches the electric telescopic rod 3. A mounting groove is opened in the middle of the bottom end of the base 1. The first gearbox 7 is installed in the mounting groove. The input end is connected to the output end of the lifting motor 8. The output end of the first gearbox 7 passes through the top of the base 1 and is fitted with a threaded post 9. The lifting post 10 is screwed onto the outer wall of the threaded post 9. An mounting plate 11 is installed on the top of the lifting post 10. Multiple support slide rods 12 are axially mounted on the top of the base 1 about the lifting post 10. Multiple connecting posts 13 are axially mounted on the outer wall of the lifting post 10. Support sleeves 14 are installed on the outer wall of the connecting posts 13. The support sleeves 14 are slidably mounted on the outer wall of the support slide rods 12. The top of the support sleeves 14 is connected to the bottom end of the mounting plate 11. The support base 18 is installed. At the top of the mounting plate 11, a rotating block 17 is rotatably mounted on the support base 18 via a rotating shaft 19. The top of the rotating block 17 is connected to the bottom of the lifting plate 16. A connecting seat 22 is rotatably mounted on the left side of the mounting plate 11. A second electric telescopic rod 23 is mounted on the connecting seat 22. The other end of the second electric telescopic rod 23 is rotatably connected to the bottom end of the lifting plate 16 via a rotating seat 15. An inclination sensor 20 is installed on the bottom right side of the lifting plate 16. A level 21 is installed in the middle of the front end of the lifting plate 16. A clamping groove is opened in the middle of the top of the lifting plate 16. A rotating rod 24 is rotatably mounted on the clamping groove. Inside the holding groove, the rear input end of the rotating rod 24 is connected to the output end of the second gearbox 25, and the input end of the second gearbox 25 is connected to the output end of the clamping motor 26. The rotating rod 24 has symmetrically opened threaded grooves at both ends. Two clamping sliders 27 are symmetrically slidably installed in the clamping groove, and the clamping sliders 27 are screwed onto the rotating rod 24. A clamping plate 28 is installed on the top of the clamping sliders 27. The top left and right sides of the lifting plate 16 have symmetrically opened guide hanging grooves. The bottom left and right sides of the clamping plate 28 have symmetrically installed hanging sliders 29, and the hanging sliders 29 are slidably installed in the guide hanging grooves.

[0020] After the overlapping column is placed on top of the lifting plate 16, the clamping motor 26 is started, which drives the rotating rod 24 to rotate via the second gearbox 25. The rotating rod 24 moves on top of the lifting plate 16 via the clamping slider 27 to clamp and fix the overlapping column, preventing it from slipping. When the clamping plate 28 moves, it drives the hanging slider 29 to slide in the guide groove, guiding and limiting it, enhancing the connection strength and ensuring stability. Multiple moving wheels 2 can move the overlapping column to the use position, improving the flexibility during use. The electric telescopic rod 3 is started, which drives the support base plate 4 to contact the ground downwards, making the electric telescopic rod 3 detach from the ground, increasing friction and preventing movement during use. When the support base plate 4 moves, it drives the I-beam guide rod 5 to slide on the base 1, providing support and guidance, improving structural strength and ensuring stability. The lifting motor 8 is started, which drives the threaded column via the first gearbox 7. 9. Rotating the lifting column 10 pushes the lifting plate 16 to adjust its height, lifting the overlapping column upwards to the usable height for easy height adjustment and improved convenience. When the lifting column 10 moves the mounting plate 11, the mounting plate 11 drives the support sleeve 14 to slide on the support slide rod 12. The support sleeve 14 and the connecting column 13 limit and guide the lifting column 10, improving structural strength and ensuring stability during lifting. The tilt sensor 20 detects the tilt angle of the lifting plate 16 in real time. If tilting occurs and the support is unsafe, an alarm is immediately triggered. At the same time, the level 21 allows staff to intuitively check the level of the lifting plate 16, improving practicality. Activating the second electric telescopic rod 23 extends and retracts, which pushes the lifting plate 16 to drive the rotating block 17 to rotate on the support seat 18, adjusting the angle of the lifting plate 16 for balance adjustment, preventing tilting and ensuring safety.

[0021] like Figures 1 to 5As shown, this utility model discloses a self-balancing support device for steel structure lap columns. During operation, after the lap column is placed on top of the lifting plate 16, the clamping motor 26 is activated, driving the rotating rod 24 to rotate via the second gearbox 25. The rotating rod 24 moves on top of the lifting plate 16 via the clamping slider 27, clamping and fixing the lap column. Multiple moving wheels 2 can move the lap column to the desired position. The electric telescopic rod 3 is activated, causing the support base plate 4 to contact the ground downwards, thus detaching the electric telescopic rod 3 from the ground to prevent movement during use. The lifting motor 8 is activated, driving the threaded column 9 to rotate via the first gearbox 7, pushing the lifting column 10 to adjust its height. The height of the lowering plate 16 lifts the overlapping column to the usable height. When the lifting column 10 moves the mounting plate 11, the mounting plate 11 drives the support sleeve 14 to slide on the support slide rod 12. The support sleeve 14 and the connecting column 13 limit and guide the lifting column 10. The tilt sensor 20 detects the tilt angle of the lifting plate 16 in real time. If tilting occurs and the support is unsafe, an alarm is immediately triggered, and the extension and retraction of the second electric telescopic rod 23 can push the lifting plate 16 to drive the rotating block 17 to rotate on the support seat 18, adjusting the angle of the lifting plate 16. At the same time, the level 21 allows the staff to intuitively detect the horizontal status of the lifting plate 16.
