DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described in detail below through specific embodiments and in combination with the accompanying drawings. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] The specific working steps of the flip structure are as follows: start the drive device 27, which can be driven by, but not limited to, a hydraulic power source. In particular, in this embodiment, the drive device 27 is driven by a dual hydraulic cylinder. Such a design can provide stable and powerful power to ensure the reliability and durability of the flip structure during operation. The drive device 27 is equipped with a displacement sensor and a high-sensitivity servo proportional valve. The coordinated work of these high-precision components enables the flip angle to be precisely controlled, including preset angles such as 0°, 30°, 45°, and 60°, to meet different operating requirements, whether it is loading, unloading or flipping operations, it can be precisely in place.

[0028] When the flip structure reaches a predetermined angle, the angle sensor will detect this change in time and quickly send a signal to the control system. After receiving the signal, the control system will instruct the locking device 16 to push out and lock the flip mechanism to ensure that the structure is stable at the required angle, effectively preventing items from falling due to accidents, thereby significantly improving the safety of the operation. In addition, when the flip table is in a horizontal position, the hydraulic buffer will intervene to slow down the descent speed of the flip table and reduce the impact, thereby effectively protecting the flip table and the items on it from damage. This measure is crucial to protecting the safety of equipment and operators.

[0029] In terms of the operation process, the operator first sets the required flip angle through the control system according to the operation requirements. After receiving the command, the drive device 27 drives the flip structure to reach the set angle through the dual hydraulic cylinders. During this process, the displacement sensor monitors the position of the flip structure in real time, and the servo proportional valve adjusts the pressure of the hydraulic cylinder according to the feedback to ensure accurate control of the angle. When the angle is in place, the angle in place sensor sends a signal, and the locking device 16 responds and locks the flip structure to ensure structural stability. When the flip table returns to the horizontal position, the hydraulic buffer works to ensure that the flip table lands smoothly and avoids damage caused by rapid descent.

[0030] Example 1: Reference Figures 1 to 7 , a heavy-duty loading platform flip structure, the flip disc 3 is connected to the flip part 4 on both sides, and bearings are installed on it to achieve flexible rotation and ensure the smoothness of the flipping action. The design of this bearing allows the flip disc 3 to maintain stable rotation when bearing a heavy load, reducing friction and wear, and extending the service life of the equipment. The driving device 27 and the locking device 16 are compactly arranged above the loading base 26. The driving device 27 is directly connected to the flip disc 3 through the flip rod 15. Such a layout not only ensures the efficient transmission of power, but also makes the entire flip structure respond quickly and accurately. This direct connection method reduces energy loss, improves flipping efficiency, and also makes the operation easier and faster.

[0031] A fan-shaped rotating disk 18 is specially designed on one side of the flip disk 3. This structure not only increases the stability of the flip disk, but also provides a point of action for the locking device 16. The function of the locking device 16 is to lock the fan-shaped rotating disk 18 to ensure the stability and safety of the structure during the flipping process and prevent accidents caused by flipping. The design of the fan-shaped rotating disk 18 takes into account the mechanical distribution, so that the force is more uniform during the flipping process, reducing the deformation and damage risks of the structure.

[0032] The two sides of the fixing plate 17 are designed as triangular clasps 24. This structure not only enhances the strength of the fixing plate, but also provides an embedding point for the fan-shaped rotating disk 18. The design of the triangular clasp 24 utilizes the stability principle of the triangle, so that the fixing plate 17 is not easy to deform when subjected to pressure. The fan-shaped rotating disk 18 is connected to the flip disk 3 after being embedded in the triangular clasp 24. This design makes the fan-shaped rotating disk more stable during the flipping process, reduces the displacement caused by vibration or impact, improves the stability and durability of the entire structure, and enables the structure to remain stable even when subjected to heavy loads.

[0033] The edge of the fan-shaped rotating disk 18 is designed with a plurality of first locking holes 19, which are the key to the function of the locking device 16. One side of the first locking hole 19 is designed as a second locking hole 20. Such a locking hole design provides multiple safeguards, ensuring that the fan-shaped rotating disk 18 can be firmly locked at different flip angles to prevent accidental movement due to external forces, thereby enhancing the safety and reliability of the structure. This design allows the flip disk to be locked quickly and accurately under different working conditions, thereby improving the flexibility and safety of the operation. One side of the fan-shaped rotating disk 18 is arc-shaped, and the arc-shaped structure makes the fan-shaped rotating disk 18 more uniform in bearing capacity, uniform in stress distribution, more stable in structure, and not easy to break.

[0034] The locking device 16 is provided with a first locker 22, which is specifically used to lock the first locking hole 19 to ensure the initial locking of the fan-shaped rotating disk 18 during the flipping process. Above the first locker 22, a second locker 21 is designed to lock the second locking hole 20 to provide additional locking protection. This double locking mechanism greatly enhances the safety of the flipping structure, and can ensure the stability and safety of the flipping structure even under extreme working conditions, preventing accidents caused by locking failure. This design takes into account various unexpected situations, ensuring that the structure can be kept stable under any circumstances, and protecting the safety of operators and equipment.

[0035] In summary, this heavy-duty loading platform flipping structure not only improves the efficiency and stability of the flipping operation through the carefully designed components and connection methods, but more importantly, greatly enhances the safety during the operation and ensures the safety of operators and equipment. This design allows the heavy-duty loading platform to more accurately control the flipping angle during the flipping operation, reducing the risks caused by improper operation or external impact, while also improving the operating efficiency and reducing maintenance costs, providing a strong guarantee for the stable operation of the heavy-duty loading platform.

[0036] Example 2: Reference Figures 1 to 7 , a heavy-duty loading platform flipping structure, the flipping part 4 connected to both sides of the flipping disc 3 is equipped with bearings to facilitate easy rotation and ensure the continuity of the flipping action. The design of the bearings enables the flipping disc 3 to maintain stable rotation even under heavy load conditions, reducing friction and wear, thereby extending the service life of the equipment. Above the loading base 26, the driving device 27 and the locking device 16 are compactly arranged on the loading base 26. The driving device 27 is directly connected to the flipping disc 3 through the flip rod 15. This design not only ensures efficient power transmission, but also enables the entire flipping structure to respond quickly and accurately. The direct connection method reduces energy loss, improves flipping efficiency, and simplifies the operation process.

[0037] On one side of the flip disk 3, a fan-shaped rotating disk 18 is specially designed. This structure not only enhances the stability of the flip disk, but also provides a point of action for the locking device 16. The function of the locking device 16 is to lock the fan-shaped rotating disk 18 to ensure the stability and safety of the structure during the flipping process and prevent accidents caused by flipping. The design of the fan-shaped rotating disk 18 takes into account the mechanical distribution, so that the force is more uniform during the flipping process, reducing the deformation and damage risks of the structure.

[0038] The two sides of the fixing plate 17 are designed as triangular clasps 24. This structure not only enhances the strength of the fixing plate, but also provides an embedding point for the fan-shaped rotating disk 18. By utilizing the stability principle of the triangle, the design of the triangular clasp 24 makes it difficult for the fixing plate 17 to deform when subjected to pressure. The fan-shaped rotating disk 18 is connected to the flip disk 3 after being embedded in the triangular clasp 24. This design makes the fan-shaped rotating disk more stable during the flipping process, reduces the displacement caused by vibration or impact, improves the stability and durability of the entire structure, and enables the structure to remain stable even when subjected to heavy loads.

[0039] The edge of the fan-shaped rotating disk 18 is designed with a plurality of first locking holes 19, which are the key to the function of the locking device 16. One side of the first locking hole 19 is designed as a second locking hole 20. Such a double locking hole design provides double protection, ensuring that the fan-shaped rotating disk 18 can be firmly locked at different flip angles to prevent accidental movement due to external forces, thereby enhancing the safety and reliability of the structure. This design allows the flip disk to be quickly and accurately locked in different working conditions, thereby improving the flexibility and safety of the operation.

[0040] The design of the locking device 16 is also ingenious, with a first locker 22 specifically used to lock the first locking hole 19 to ensure the initial locking of the fan-shaped rotating disk 18 during the flipping process. Above the first locker 22, a second locker 21 is designed to lock the second locking hole 20 to provide additional locking protection. This double locking mechanism greatly enhances the safety of the flip structure, ensuring the stability and safety of the flip structure even under extreme working conditions and preventing accidents caused by locking failure. This design takes into account various unexpected situations, ensuring that the structure can be kept stable under any circumstances and protecting the safety of operators and equipment.

[0041] The structure is specially designed with a positioning block 25 on one side of the flip plate 3. A connecting shaft 23 is installed inside the positioning block 25. The connecting shaft 23 is used to fix the flip rod 15 to ensure that the flip rod maintains the correct position and stable movement trajectory during the flipping process. This design not only improves the accuracy of the flip structure, but also enhances its durability and reliability, because the coordinated use of the positioning block 25 and the connecting shaft 23 reduces the possible deviation or looseness of the flip rod under high-load working conditions, thereby ensuring the consistency and predictability of the flipping action, which is crucial for heavy-duty loading platforms that require high-precision operations.

[0042] A flip seat 5 is fixed below the flip part 4. The flip seat 5 is designed as a triangular seat structure. Such a structure is known for its inherent stability and can provide additional support and balance during the flipping process. The flip seat 5 is fixed above the flip base 6. This layout makes the center of gravity of the entire flip structure lower, thereby increasing the stability and safety of the platform, especially when carrying heavy goods. The low center of gravity design helps to reduce the risk of tipping over, and also allows the platform to remain stable on uneven ground, which is particularly important for operations in outdoor or industrial environments.

[0043] Several trapezoidal blocks 7 are cleverly connected inside the flip base 6 to form a cavity 10. This cavity 10 not only reduces the weight of the structure and improves the efficiency of material use, but can also be used to store maintenance tools or as a passage for cables and pipes. This design allows the flip base 6 to provide additional storage space or wiring paths while maintaining structural strength, increasing the versatility of the design. At the same time, a number of fixing holes 8 are provided at the bottom of the flip base 6. These fixing holes 8 are used to fix the flip base to ensure the stability and safety of the platform during use. The design of these fixing holes 8 takes into account the needs of different installation scenarios.

[0044] Example 3: Reference Figures 1 to 7 , a heavy-duty loading platform flip structure, The flipping parts 4 on both sides of the flipping disc 3 are equipped with bearings. The design of these bearings allows the flipping disc to maintain smooth rotation even under heavy loads, ensuring the continuity of the flipping action. The configuration of the bearings helps to reduce friction and wear during the flipping process, thereby extending the service life of the equipment. A drive device 27 and a locking device 16 are compactly installed above the loading base 26. The drive device 27 is connected to the flipping disc 3 through a flip rod 15. Such a layout not only ensures efficient power transmission, but also enables the entire flipping structure to respond quickly and accurately to operating instructions. The direct connection method reduces energy loss, improves flipping efficiency, and simplifies the operating process.

[0045] On one side of the flip disk 3, a fan-shaped rotating disk 18 is specially designed. This structure not only enhances the stability of the flip disk, but also provides a point of action for the locking device 16. The function of the locking device 16 is to lock the fan-shaped rotating disk 18 to ensure the stability and safety of the structure during the flipping process and prevent accidents caused by flipping. The design of the fan-shaped rotating disk 18 takes into account the mechanical distribution, so that the force is more uniform during the flipping process, reducing the deformation and damage risks of the structure.

[0050] A flip seat 5 is fixed below the flip part 4. The flip seat 5 is designed as a triangular seat structure. Such a structure has better stability and can provide additional support and balance during the flipping process. The flip seat 5 is fixed above the flip base 6. This layout makes the center of gravity of the entire flip structure lower, thereby increasing the stability and safety of the platform, especially when carrying heavy goods. The low center of gravity design helps reduce the risk of tipping over, and also allows the platform to remain stable on uneven ground, which is particularly important for operations in outdoor or industrial environments.

U-shaped long plates 11 are fixed in these slots 9. The design of the slots 9 also allows cables or pipes to pass through, which is convenient for wiring and maintenance work, while reducing external interference and improving the overall aesthetics of the platform.

[0052] A rotating rod 12 is designed in the flip part 4, and the rotating rod 12 is connected to the flip disk 3 through an L-shaped fixing block 13. The design of the L-shaped fixing block 13 provides a stable connection point, so that the rotating rod 12 can effectively transmit power and drive the flip disk 3 to flip. This connection method not only ensures the stability of power transmission, but also reduces the vibration and noise that may occur during the flipping process, thereby improving the working performance and service life of the flip structure. A number of built-in cavities 14 are provided on the flip disk 3. These cavities 14 can be used to reduce the weight of the flip disk and improve the efficiency of material use. At the same time, they also provide space for the installation and maintenance of internal components.

[0053] A rotating disk 2 is connected above the overturning disk 3, and a material tray 1 is further connected above the rotating disk 2. This multi-layer structure design enables the overturning structure to adapt to a variety of loading and unloading needs. The rotating disk 2 can rotate around the overturning disk 3, so that the goods on the material tray 1 can be easily adjusted to the best position for loading and unloading. This design not only improves work efficiency, but also reduces the labor intensity of operators during loading and unloading, making the operation of the entire loading platform easier and faster.
