[0010] The beneficial effects of adopting the above-mentioned further solution are: the first roller and the second roller on the first support frame and the second support frame are arranged opposite to each other and at an inclination, which can stably support the tubular material horizontally. At the same time, when the pushing component pushes the material to move, the first roller and the second roller roll and rub against each other, which reduces the friction and can also effectively protect the surface of the material.

[0011] Furthermore, a hinge is installed on the lower side of one end of the support plate, and a hinge seat is installed on the base. The hinge pin passes through the hinge and is connected to the hinge seat.

[0015] Furthermore, the pushing assembly includes a pushing plate located on the upper side of the support plate, and a connector is installed on the lower side of the pushing plate.

[0017] Furthermore, the power assembly includes a first rotating rod and a second rotating rod. The first rotating rod and the second rotating rod are respectively mounted on the lower side of the support plate through a third shaft mounting seat and a fourth shaft mounting seat. A first synchronous gear is mounted on both ends of the first rotating rod, and a second synchronous gear is mounted on both ends of the second rotating rod. The first synchronous gear and the second synchronous gear are connected by a synchronous belt, and the connecting piece is connected to the synchronous belt. A power motor is also installed on the lower side of the support plate, and a reducer is installed at the output end of the power motor. The reducer is connected to the first rotating rod.

Detailed Implementation

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] In the description of this utility model, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "inner", "outer", "circumferential", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an automatic loading and unloading device suitable for overhead conveyor lines includes a support plate 1. The support plate 1 is made of high-strength alloy material and has excellent load-bearing performance and structural stability. Rolling support assembly 2, multiple rolling support assemblies 2 are installed on support plate 1. The rolling support assembly 2 is used to support tubular materials. The spacing between multiple rolling support assemblies 2 is adjusted according to the length specifications of common tubular materials to ensure that a single tubular material can be supported by at least two sets of rolling support assemblies 2 at the same time, effectively avoiding deformation or displacement of the material due to single-point force. The rolling support assembly 2 is detachably connected to support plate 1 by bolts, which is convenient for subsequent maintenance and replacement. It provides reliable support when the tubular material is stationary, and reduces resistance through rolling friction when the material moves. The base 3 is hinged to the support plate 1 on one side. A hinged lifting assembly 4 is installed between the base 3 and the support plate 1. The base 3 is made of heavy steel plate welded together and has anti-slip and shock-absorbing pads at the bottom. It can be directly fixed to the ground or production line base to ensure the stability of the device during operation. The material pushing assembly 5 is mounted on the support plate 1 and located on the side wall of the rolling support assembly 2, specifically at the end, and is used to push the material so as to suspend it on the conveyor line. The articulated lifting assembly 4 pushes the support plate 1 to rotate around the base 3, causing the tubular material on the rolling support assembly 2 to change from horizontal to inclined, and the pushing assembly 5 pushes the tubular material to move along the support plate 1 to suspend the material on the conveyor line.

[0028] During the specific operation, the articulated lifting assembly 4 is activated and outputs driving force. The driving force acts on the lower surface of the support plate 1, pushing the support plate 1 to slowly rotate around the hinge point of the base 3. As the tilt angle of the support plate 1 gradually increases, the tubular material that was originally placed on the rolling support assembly 2 in a horizontal state gradually changes to an inclined state under the guidance of gravity and the rolling support assembly 2. At this time, one end of the tubular material will be lifted towards the direction of the suspended conveyor line.

[0029] Once the support plate 1 reaches the preset tilt angle, the hinged lifting assembly 4 stops moving and maintains its current posture. Then, the pushing assembly 5 starts moving along the surface of the support plate 1 towards the suspended conveyor line under the drive of the power assembly. The front end of the pushing assembly 5 contacts the end face of the tubular material and applies a uniform pushing force, pushing the tubular material to move smoothly along the rolling direction of the rolling support assembly 2. Because the roller structure of the rolling support assembly 2 converts sliding friction into rolling friction, it greatly reduces the resistance during the material movement, allowing the material to maintain a uniform speed movement under a small pushing force. Finally, under the continuous pushing of the pushing assembly 5, one end of the tubular material is successfully hooked near the hook of the suspended conveyor line. Then, the pushing assembly 5 moves in the opposite direction so that the end of the tubular material is hooked on the hook on the conveyor track, completing the automatic loading action.

[0030] To achieve the unloading function, simply reverse the control of the hinged lifting assembly 4 and the pushing assembly 5. First, the pushing assembly 5 receives the tubular material on the suspended conveyor line onto the rolling support assembly 2. Then, the hinged lifting assembly 4 drives the support plate 1 to return to a horizontal state, thus completing the automatic unloading of the material.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the rolling support assembly 2 includes a first support frame 6 and a second support frame 7. Both the first support frame 6 and the second support frame 7 are made of bent steel plates and are fixed to the support plate 1 in a symmetrical structure. A first roller 8 is installed on the first support frame 6, and a second roller 9 is installed on the second support frame 7. The first roller 8 and the second roller 9 can be made of high-strength wear-resistant rubber material with anti-slip textures on the surface, which can prevent the material from sliding during the support process and prevent scratch damage to the material surface. The first roller 8 and the second roller 9 are arranged opposite to each other and at an angle. The tubular material is located between the first roller 8 and the second roller 9. Through the relative inclination of the first roller 8 and the second roller 9, their axes form a certain angle with the surface of the support plate 1, which can stably support the tubular material horizontally. When the pushing assembly 5 pushes the material to move, the first roller 8 and the second roller 9 will roll and rub, thereby reducing friction and effectively protecting the material surface and avoiding wear caused by direct contact.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, a hinge 10 is installed on the lower side of one end of the support plate 1, and a hinge seat 11 is installed on the base 3. A hinge pin 12 passes through the hinge 10 and connects to the hinge seat 11. The hinge pin 12 and the pin hole are clearance-fitted, allowing the support plate 1 to rotate flexibly around the hinge pin 12. The hinge structure not only achieves a reliable connection between the support plate 1 and the base 3, ensuring the structural strength of the device, but also reduces assembly difficulty through a simple pin connection method, facilitating later maintenance and repair. In addition, the ear plate structure of the hinge 10 and the hinge seat 11 can withstand a large radial force, ensuring that the hinge will not deform or be damaged when the support plate 1 is carrying heavy objects and tilting, effectively extending the service life of the device.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in another embodiment, the articulated lifting assembly 4 includes an articulated electric cylinder 13. The articulated electric cylinder 13 has a precise position control function, which can accurately adjust the extension and retraction amount according to the instructions of the control system, thereby precisely controlling the tilt angle of the support plate 1. The bottom of the articulated electric cylinder 13 is connected to a first rotating shaft 14. The two ends of the first rotating shaft 14 are mounted on the base 3 through a first shaft mounting seat 15. The output end of the articulated electric cylinder 13 is connected to a second rotating shaft 16. The two ends of the second rotating shaft 16 are mounted on the support plate 1 through a second shaft mounting seat 17. When the piston rod of the articulated electric cylinder 13 extends, it applies an upward thrust to the support plate 1 through the second rotating shaft 16. Since one end of the support plate 1 is hinged to the base 3, the support plate 1 will rotate upward around the hinge point under the action of the thrust, thereby increasing the tilt angle. Conversely, when the piston rod retracts, it applies a downward pull to the support plate 1, causing the support plate 1 to rotate downward around the hinge point and return to a horizontal state, thereby changing the tilt angle of the tubular material.

[0034] like Figure 1 , Figure 2 As shown, in one embodiment, the pushing assembly 5 includes a pushing plate 18, which is located on the upper side of the support plate 1. A connector is installed on the lower side of the pushing plate 18, passing through the support plate 1 and connected to the power assembly. The support plate 1 has a sliding groove 19 that mates with the connector, and the sliding groove 19 is arranged along the length direction of the support plate 1. A guide rail 29 is also installed on the support plate 1, and a slider 30 that mates with the guide rail 29 is installed on the lower side of the pushing plate 18. The power assembly drives the connector to move along the sliding groove 19, while the slider 30 slides synchronously along the guide rail 29. The dual guiding structure ensures the straightness of the pushing plate 18 during movement, preventing the pushing plate 18 from tilting or deviating, thereby ensuring that the tubular material can move smoothly along the preset path and accurately dock with the suspended conveyor line.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in the specific embodiment, the power assembly includes a first rotating rod 20 and a second rotating rod 21. Both the first rotating rod 20 and the second rotating rod 21 are made of high-strength hollow round tubes. The two ends of the first rotating rod 20 and the second rotating rod 21 are respectively mounted on the lower side of the support plate 1 through a third shaft mounting seat 22 and a fourth shaft mounting seat 23. Both the third shaft mounting seat 22 and the fourth shaft mounting seat 23 adopt a bearing seat structure and have tapered roller bearings installed inside, which can withstand radial and axial forces to ensure that the rotating rods remain stable when rotating at high speed. The first rotating rod 20 is equipped with a first synchronous gear 24 at both ends, and the second rotating rod 21 is equipped with a second synchronous gear 25 at both ends. The first synchronous gear 24 and the second synchronous gear 25 are connected by a synchronous belt 26, and a connecting piece is connected to the synchronous belt 26. A power motor 27 is also installed on the lower side of the support plate 1. The power motor 27 is a servo motor, and a reducer 28 is installed at the output end of the power motor 27. The reducer 28 is connected to the first rotating rod 20. During operation, the power motor 27 starts, and the high-speed rotational motion output is reduced by the reducer 28 and converted into low-speed, high-torque rotation of the first rotating rod 20. The first rotating rod 20 drives the first synchronous gear 24 at both ends to rotate. Through the meshing transmission of the synchronous belt 26, it drives the second synchronous gear 25 to rotate synchronously with the second rotating rod 21. At this time, the synchronous belt 26 moves linearly along the gear trajectory, thereby driving the pusher plate 18 to move smoothly and push the tubular material. By adjusting the speed of the power motor 27, the moving speed of the pusher plate 18 can be precisely controlled. By setting the number of rotations of the motor, the moving distance of the pusher plate 18 can be precisely controlled, thereby meeting the pushing requirements of tubular materials of different specifications and ensuring that the material can be accurately attached to the suspended conveyor line.
