Description

Technical Field

[0001] This specification relates to one or more embodiments in the field of steel structure flipping technology, and more particularly to a steel structure flipping device. Background Technology

[0002] The steel structure flipping device safely and efficiently flips large and heavy steel structure components, transforming the welding, inspection and assembly processes that originally required a lot of manpower and high-risk aerial operations into safe, precise and efficient low-level operations on the ground, thereby fundamentally ensuring construction safety and improving project quality and construction speed.

[0003] There is an existing Chinese utility model patent with application number 2023106149358, entitled "A Steel Structure Flipping Device." The description states that "by operating the adjustment mechanism, the first clamping seat is pushed closer to the second clamping seat until both sides of the steel plate are locked in the two clamping slots, which can firmly clamp the steel plate and prevent it from falling off during the flipping process. The braking mechanism can position and fix the driven gear, preventing the rotating shaft from rotating arbitrarily, allowing the steel plate to maintain the same orientation, thus facilitating steel plate processing. By holding the handle and rotating the rotating rod, the driving gear can be driven to rotate synchronously. The rotating driving gear meshes with and drives the driven gear, which in turn drives the rotating shaft to rotate, thereby rotating the steel plate and realizing the flipping of the steel plate." However, the description of locking the steel plate in the clamping slots on both sides suggests that the steel plate may fall off due to its own weight during flipping. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a steel structure flipping device to solve the problem that the existing flipping device is not firmly clamping the steel structure.

[0005] To achieve the above objectives, this utility model provides a steel structure flipping device, including a movable plate, with a movable component disposed above the movable plate for flipping steel materials;

[0006] The moving component includes a second lead screw, through which the moving component passes. One end of the second lead screw is connected to a second motor. A suspension hook is fixedly connected to the bottom of the moving component. The suspension hook has an opening, and a connecting ring is hung on the suspension hook through the opening. The bottom of the connecting ring is connected to a hanging chain or a cloth belt through gear engagement.

[0007] The hanging chain is used to hold the steel, and the moving component moves the steel to complete the flipping.

[0008] The two ends of the chain are respectively fixedly connected to a hanging ring and a hook. The hook is C-shaped, and the hanging ring has a through hole in the middle. The hanging ring passes through the opening of the hook and is fixedly connected to the hook.

[0009] Preferably, limiting rods are provided on both sides of the second lead screw, and the moving component is driven by the second motor to move horizontally on the second lead screw and the limiting rods, thereby enabling the steel structure to complete the flipping.

[0010] Preferably, one end of the second lead screw is fixedly connected to the slider, the slider is sleeved on the first lead screw, a track is provided on the outside of the slider, and one end of the track is connected to the first motor;

[0011] The other end of the second lead screw is fixedly connected to the second motor. Another slider is connected to the outside of the second motor. The slider is sleeved on another first lead screw. A track is provided outside the slider. One end of the track is connected to the first motor.

[0012] The sliders on both sides of the second lead screw are used to synchronously drive the moving component to move horizontally.

[0013] Preferably, an anti-slip pad is fixedly connected to the surface of the movable plate to protect the steel structure surface from mechanical damage;

[0014] The bottom of the movable plate is connected to a moving track, which is used to move the steel on the surface of the movable plate.

[0015] Preferably, the two ends of the track are fixedly connected to the bracket, the bottom of the bracket is fixedly connected to the support leg, and the two ends of the support leg on both sides are fixedly connected to the movable track.

[0016] Preferably, the auxiliary plate is connected to one side of the movable plate via a hinge. The auxiliary plate is L-shaped and can be rotated 90° on one side of the movable plate via the hinge.

[0017] As can be seen from the above, the steel structure flipping device provided by this utility model uses a hanging chain instead of a clamping mechanism. By fixing the moving plate, the hanging chain hangs on one end of the steel, and the moving component drives the steel to move and complete the flipping. Alternatively, the steel can be placed on the moving plate, the hanging chain hangs on one end of the steel and lifts it to a certain height, and the moving plate drives the steel to move and complete the flipping. Or the steel can be placed on the surface of the auxiliary plate and flipped 90°. Multiple methods are used to assist the steel in completing the flipping, reducing the pressure of manual flipping and reducing damage to the steel. Attached Figure Description

[0027] Example 1:

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a steel structure flipping device is provided, including a movable plate 5, and a movable component 3 is arranged above the movable plate 5 for flipping steel.

[0029] The moving component 3 includes a second lead screw 21, through which the moving component 3 passes. One end of the second lead screw 21 is connected to a second motor 2. The bottom of the moving component 3 is fixedly connected to a suspension hook 31. The suspension hook 31 has an opening, and a connecting ring 4 is hung on the suspension hook 31 through the opening. The bottom of the connecting ring 4 is connected to a hanging chain 41 or a cloth belt through gear meshing.

[0030] The hanging chain 41 is used to hang the steel, and the moving component 3 moves the steel to complete the flipping.

[0031] The two ends of the chain 41 are respectively fixedly connected to a hanging ring 411 and a hook 412. The hook 412 is C-shaped. The hanging ring 411 has a through hole in the middle. The hanging ring 411 passes through the opening of the hook 412 and is fixedly connected to the hook 412.

[0032] The second lead screw 21 serves as the transmission core of the moving component 3, providing it with stable horizontal movement power. The hanging hook 31 at the bottom of the moving component 3, with its open design, allows for quick assembly and disassembly with the connecting ring 4, significantly shortening the preparation time before steel structure hoisting. The gear meshing connection between the connecting ring 4 and the hanging chain 41 ensures a secure connection, preventing steel from falling due to loosening during the flipping process. Furthermore, it allows for flexible switching of the mounting components depending on the type of steel. For smooth, high-hardness steel structures, such as stainless steel plates, the hanging chain 41 is used, with fastening achieved through the cooperation of the metal hanging ring 411 and the hook 412. For precision steel structures with easily scratched surfaces, such as painted steel plates, a cloth strap can be used, utilizing its flexibility to reduce mechanical damage and achieving versatility.

[0033] Furthermore, the fixed connection between the hanging rings 411 and the hooks 412 at both ends of the hanging chain 41 forms a closed-loop hanging structure. Compared with traditional open chains, this structure can evenly distribute the weight of the steel, avoiding excessive local stress that could lead to steel deformation. Especially for long steel structures exceeding 5 meters in length, it can effectively control the deformation error during the flipping process to within 0.5mm, ensuring the processing accuracy of the steel structure. The length of the hanging chain can also be adjusted according to actual usage.

[0034] Limiting rods 22 are provided on both sides of the second lead screw 21. The second motor 2 drives the moving component 3 to move horizontally on the second lead screw 21 and the limiting rods 22, thereby completing the flipping of the steel structure. This ensures the safety of the flipping process and prevents the steel from tilting and falling due to the displacement of the moving component.

[0035] The movable plate 5 is connected to the auxiliary plate 53 via a hinge on one side. The auxiliary plate 53 is L-shaped and can be rotated 90° on one side of the movable plate 5 via the hinge. When dealing with cylindrical steel structures, the auxiliary plate 53 can be placed horizontally, the steel material can be placed on the auxiliary plate, the auxiliary plate can be manually supported and lifted 90°, and then the steel material can be laid flat in the opposite direction to complete the rotation.

[0036] Meanwhile, the hinge connection of the auxiliary plate 53 has a buffering characteristic. During the flipping process, the angle can be slowly adjusted through the damping effect of the hinge, avoiding the impact caused by the rapid flipping of the auxiliary plate 53 and its collision with the steel. For steel structures with precision components such as pre-installed bolts attached to the surface, it can effectively protect the components from collision damage and reduce subsequent rework costs. In addition, the auxiliary plate 53 is made of lightweight aluminum alloy, weighing only 1 / 3 of the traditional steel auxiliary plate. Operators can manually complete the flipping and adjustment without additional power equipment, reducing the energy consumption and operational complexity of the device.

[0037] Example 2:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a steel structure flipping device is provided, including a movable plate 5, and a movable component 3 is arranged above the movable plate 5 for flipping steel.

[0039] The moving component 3 includes a second lead screw 21, through which the moving component 3 passes. One end of the second lead screw 21 is connected to a second motor 2. The bottom of the moving component 3 is fixedly connected to a suspension hook 31. The suspension hook 31 has an opening, and a connecting ring 4 is hung on the suspension hook 31 through the opening. The bottom of the connecting ring 4 is connected to a hanging chain 41 or a cloth belt through gear meshing.

[0040] The hanging chain 41 is used to hang the steel, and the moving component 3 moves the steel to complete the flipping.

[0041] The two ends of the chain 41 are respectively fixedly connected to a hanging ring 411 and a hook 412. The hook 412 is C-shaped. The hanging ring 411 has a through hole in the middle. The hanging ring 411 passes through the opening of the hook 412 and is fixedly connected to the hook 412.

[0042] The second lead screw 21 serves as the transmission core of the moving component 3, providing it with stable horizontal movement power. The hanging hook 31 at the bottom of the moving component 3, with its open design, allows for quick assembly and disassembly with the connecting ring 4, significantly shortening the preparation time before steel structure hoisting. The gear meshing connection between the connecting ring 4 and the hanging chain 41 ensures a secure connection, preventing steel from falling due to loosening during the flipping process. Furthermore, it allows for flexible switching of the mounting components depending on the type of steel. For smooth, high-hardness steel structures, such as stainless steel plates, the hanging chain 41 is used, with fastening achieved through the cooperation of the metal hanging ring 411 and the hook 412. For precision steel structures with easily scratched surfaces, such as painted steel plates, a cloth strap can be used, utilizing its flexibility to reduce mechanical damage and achieving versatility.

[0043] Furthermore, the fixed connection between the hanging rings 411 and the hooks 412 at both ends of the hanging chain 41 forms a closed-loop hanging structure. Compared with traditional open chains, this structure can evenly distribute the weight of the steel, avoiding excessive local stress that could lead to steel deformation. Especially for long steel structures exceeding 5 meters in length, it can effectively control the deformation error during the flipping process to within 0.5mm, ensuring the processing accuracy of the steel structure. The length of the hanging chain can also be adjusted according to actual usage.

[0044] Limiting rods 22 are provided on both sides of the second lead screw 21. The second motor 2 drives the moving component 3 to move horizontally on the second lead screw 21 and the limiting rods 22, thereby completing the flipping of the steel structure. This ensures the safety of the flipping process and prevents the steel from tilting and falling due to the displacement of the moving component.

[0045] One end of the second lead screw 21 is fixedly connected to the slider 122. The slider 122 is sleeved on the first lead screw 121. A track 12 is provided on the outside of the slider 122. One end of the track 12 is connected to the first motor 13.

[0046] The other end of the second lead screw 21 is fixedly connected to the second motor 2. Another slider 122 is connected to the outside of the second motor 2. The slider 122 is sleeved on another first lead screw 121. A track 12 is provided on the outside of the slider 122. One end of the track 12 is connected to the first motor 13.

[0047] The sliders 122 on both sides of the second lead screw 21 are used to synchronously drive the moving component 3 to move horizontally. The PLC system ensures that the two motors rotate at the same speed, ensuring that the moving speed of the sliders 122 on both sides is completely synchronized. This keeps the second lead screw 21 in a horizontal state at all times and avoids tilting of the second lead screw due to the excessive movement of one side of the slider, which would cause shaking when the steel is flipped.

[0048] The surface of the movable plate 5 is fixedly connected to an anti-slip pad 51 to protect the steel structure surface from mechanical damage. The anti-slip pad 51 is made of high-density rubber and has a diamond-shaped anti-slip texture on its surface. On the one hand, it can increase the friction between the steel and the movable plate 5. When the steel is placed on the movable plate 5, the anti-slip pad can increase the coefficient of friction and prevent the steel from slipping during the preparation stage before the movable plate moves or flips. On the other hand, the flexibility of the rubber material can buffer the impact force when the steel is placed. For steel structures with fine textures on the surface, such as carved steel plates, it can effectively prevent damage to the texture caused by mechanical collisions and reduce the scrap rate.

[0049] The bottom of the movable plate 5 is connected to a movable track 52, which is used to move the steel on the surface of the movable plate 5. Before the flipping operation, the steel can be directly transported from the raw material storage area to the underside of the flipping device via the movable track 52, eliminating the need for manual handling and saving labor costs for operators. After the flipping is completed, the movable plate 5 can transfer the steel to the next processing step, such as welding or spraying, via the movable track 52, reducing the time loss in intermediate transfer links.

[0050] The two ends of the track 12 are fixedly connected to the bracket 11, the bottom of the bracket 11 is fixedly connected to the support leg 1, and the two ends of the support leg 1 on both sides are fixedly connected to the movable track 52.

[0051] The movable plate 5 is connected to the auxiliary plate 53 via a hinge on one side. The auxiliary plate 53 is L-shaped and can be rotated 90° on one side of the movable plate 5 via the hinge. When dealing with cylindrical steel structures, the auxiliary plate 53 can be placed horizontally, the steel material can be placed on the auxiliary plate, the auxiliary plate can be manually supported and lifted 90°, and then the steel material can be laid flat in the opposite direction to complete the rotation.

[0052] Meanwhile, the hinge connection of the auxiliary plate 53 has a buffering characteristic. During the flipping process, the angle can be slowly adjusted through the damping effect of the hinge, avoiding the impact caused by the rapid flipping of the auxiliary plate 53 and its collision with the steel. For steel structures with precision components such as pre-installed bolts attached to the surface, it can effectively protect the components from collision damage and reduce subsequent rework costs. In addition, the auxiliary plate 53 is made of lightweight aluminum alloy, weighing only 1 / 3 of the traditional steel auxiliary plate. Operators can manually complete the flipping and adjustment without additional power equipment, reducing the energy consumption and operational complexity of the device.

[0053] Working principle: The operator places the steel structure to be flipped, such as steel plate or H-beam, on the surface of the moving plate 5. The anti-slip pad 51 on the surface of the moving plate 5 increases the coefficient of friction to prevent the steel from slipping during the conveying process. Then, the moving track 52 drives the moving plate 5 and the steel to be accurately conveyed to the flipping operation area, that is, directly below the second lead screw 21.

[0054] Once the steel arrives at the work area, the lateral position of the flipping mechanism is adjusted to match the width of the steel via a bidirectional synchronous transmission system consisting of the first lead screw 121, the slider 122, and the first motor 13. The first motor 13 at one end of the two side tracks 12 is then activated, driving the first lead screw 121 to rotate and causing the slider 122 mounted on the lead screw to move laterally along the track 12. The two first motors 13 achieve synchronized speeds through a PLC system, ensuring that the sliders 122 at both ends of the second lead screw 21 move at the same speed, keeping the second lead screw 21 horizontal and preventing subsequent flipping imbalance due to unilateral deviation. During the movement of the slider 122, the second lead screw 21 and the moving component 3 below it move laterally synchronously until the hook 31 at the bottom of the moving component 3 aligns with the center of gravity of the steel.

[0055] For smooth, high-hardness steel structures, such as stainless steel plates, a hanging chain 41 is used. The C-shaped hooks 412 at both ends of the hanging chain 41 are fitted against the edges of the steel. After the hanging ring 411 passes through the opening of the hook 412, a bolt is inserted through the central through-hole for secondary fixation, forming a closed loop that evenly wraps the steel. For precision steel structures with easily scratched surfaces, such as painted steel plates, a cloth strip is used instead. This strip is connected to the suspension hook 31 at the bottom of the moving component 3 via a connecting ring 4. The flexible material of the cloth strip protects the steel surface. The hanging chain 41 meshes with the gear at the bottom of the connecting ring 4. A motor drives the gear to rotate, thus moving the hanging chain. The steel can be placed inside the hanging chain, rotating as the chain rotates. An auxiliary belt can be used to maintain the steel's balance during rotation. Alternatively, the hanging chain can be passed through one end of the steel and dragged from one end of the second lead screw 21 to the other end, completing the steel's rotation.

[0056] When dealing with cylindrical steel structures, the auxiliary plate 53 can be placed horizontally, the steel material placed on the auxiliary plate, the auxiliary plate manually supported and lifted 90°, and then the steel material laid flat in the opposite direction to complete the flipping.
