Technical Field

[0001] This utility model belongs to the field of logistics and transportation technology, specifically relating to a tractor-mounted flatbed truck. Furthermore, this utility model also relates to a material transfer system including the tractor-mounted flatbed truck. Background Technology

[0002] With the rapid development of intelligent manufacturing, the demand for logistics automation is increasing. Hidden AGVs (Automated Guided Vehicles), as efficient and flexible material handling equipment, are widely used in factories, warehouses, and other locations. Hidden AGVs can enter the bottom of material boxes and lift them using their own lifting devices to perform material handling operations.

[0003] The current transfer process first involves using a submersible automated guided vehicle (AGV) to lift the material frames and transport them to the receiving area of ​​the shipping platform. Manual forklifts then load the frames onto flatbed trucks, which are subsequently towed by a tractor unit for material transfer. Because the transfer process relies on manual forklift loading, it increases transfer time and poses certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of low efficiency caused by the need for manual forklift transfer in existing technology for traction flatbed trucks, and to provide a traction flatbed truck with an outwardly opening docking area on one edge of the carrying plate, which eliminates the need for manual forklift transfer and effectively improves the efficiency of cargo transfer.

[0005] To achieve the above objectives, the present invention provides a traction flatbed vehicle, including a support plate and wheels disposed at the bottom of the support plate. The support plate has a docking area that opens outward from one of its edges, allowing a submersible guide vehicle loaded with a material frame to run into the docking area from the opening side and transport the material frame directly above the support plate.

[0006] In some embodiments, an upwardly protruding stop is formed on the upper surface of the support plate near the docking area.

[0007] In some embodiments, the support plate includes two parallel side plates and a connecting plate located at the ends of the two side plates to form a docking area between the two side plates. Each of the two side plates is provided with a guide strip for guiding the material frame to move directly above the support plate as the submersible guide vehicle moves toward the docking area.

[0008] In some embodiments, along the direction toward the connecting plate, the portion of the guide bar on the opening side adjacent to the docking area is inclined toward the docking area.

[0009] In some embodiments, a frame for connecting the support plate and the wheels is also included, on which a towing assembly for connecting a tractor is attached.

[0010] In some embodiments, the towing assembly includes a rotating shaft connected to the vehicle frame and extending perpendicular to the towing direction, a towing bar rotatably connected to the vehicle frame via the rotating shaft, and a spare towing hook disposed on the other side of the vehicle frame opposite the towing bar.

[0011] In some embodiments, a weighing sensor is provided between the support plate and the wheel.

[0012] In some embodiments, a canopy is provided on the support plate.

[0013] In some embodiments, the wheels are provided with lockable brake pads.

[0014] The second aspect of this utility model provides a material transfer system, including a material frame for holding materials, a submersible guide vehicle for transporting the material frame, and the aforementioned traction flatbed vehicle, wherein the width of the docking area is greater than the width of the submersible guide vehicle and less than the width of the material frame.

[0015] Through the above technical solution, the present invention provides a traction flatbed truck with an outwardly opening docking area formed on one side edge of the bearing plate. After the submerged guide vehicle carrying the material frame enters the docking area, it lowers its own lifting device to place the material frame on the bearing plate, thus completing the transfer of the material frame. There is no need for manual forklift transfer, which effectively improves the transfer efficiency of goods and avoids safety hazards.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0034] like Figures 1 to 7 As shown, the present invention provides a traction flatbed vehicle, including a support plate 1 and wheels 2 disposed at the bottom of the support plate 1. The support plate 1 has a docking area 101 that opens outward from one side edge, allowing a submersible guide vehicle 5 loaded with a material frame 4 to run into the docking area 101 from the opening side and transport the material frame 4 to the top of the support plate 1.

[0035] Specifically, the top of the submersible guided vehicle 5 has a liftable lifting device, which automatically guides the vehicle to the bottom of the material frame 4, and then lifts the material frame 4 to perform the transport operation. The traction flatbed provided by this utility model has an outwardly opening docking area 101 formed on one side edge of the support plate 1 used to carry the material frame 4 (e.g., Figure 3(As shown). The submersible guided vehicle 5, carrying the material frame 4, drives into the docking area 101, then lowers its top lifting device to place the material frame 4 on the upper surface of the support plate 1 near the docking area 101 to complete the transfer. By creating a docking area 101 on the support plate 1 that can accommodate the submersible guided vehicle 5, the submersible guided vehicle 5 carrying the material frame 4 can directly drive into the towing flatbed truck and place the material frame 4 on the support plate 1, eliminating the need for manual forklift transfer, effectively improving the efficiency of goods handling and avoiding the safety hazards of forklift transfer.

[0036] like Figure 2 As shown, in some embodiments, a protruding stop portion 102 is formed on the upper surface of the support plate 1 near the docking area 101.

[0037] Normally, to facilitate forklift handling, the material frame 4 is equipped with legs extending from its bottom crossbeam. After being placed by the submersible guide trolley 5, the legs of the material frame 4 rest near the docking area 101 of the support plate 1. To prevent the legs of the material frame 4 from falling into the docking area 101 due to inertia during the movement of the towing flatbed trolley, causing material to fall off, a stop 102 is provided on the support plate 1 near the docking area 101 to prevent the legs from shifting. Figure 2 As shown, the support plate 1 has a stop portion 102 protruding from its upper surface on the side of the docking area 101.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments, the support plate 1 includes two parallel side plates 103 and a connecting plate 104 located at the ends of the two side plates 103 to form a docking area 101 between the two side plates 103. The two side plates 103 are respectively provided with guide strips 105 for guiding the material frame 4 to move directly above the support plate 1 as the submersible guide vehicle 5 moves toward the docking area 101.

[0039] Specifically, the support plate 1 forms a C-shaped structure with an opening on one side through two parallel side plates 103 and a connecting plate 104 located at the ends of the two side plates 103. The opening of the C-shaped structure is the docking area 101 for accommodating the submersible guide vehicle 5. In addition, during the process of the submersible guide vehicle 5 lifting and transferring the material frame 4, there will inevitably be a situation where the material frame 4 is misaligned. Therefore, guide strips 105 are provided on the side plates 103 located on both sides of the docking area 101 in the direction in which the submersible guide vehicle 5 enters the docking area 101. By adjusting the lifting height of the submersible guide vehicle 5, the edge of the material frame 4 can be limited by the surface of the guide strip 105 facing the docking area 101, so that the material frame 4 can move smoothly with the submersible guide vehicle 5 to directly above the support plate 1.

[0040] In some embodiments, the opposite sides of the guide bar 105 and the stop portion 102 together form a guide channel for the support legs of the guide frame 4. The guide channel limits the movement direction of the material frame 4 through the support legs of the material frame 4 during the process of the submersible guide vehicle 5 entering the docking area 101, so as to improve the stability of the transfer operation.

[0041] like Figure 3 and Figure 4 As shown, in some embodiments, along the direction toward the connecting plate 104, the portion of the guide strip 105 on the opening side adjacent to the docking area 101 is inclined toward the docking area 101. Specifically, as Figure 3 As shown, the spacing between the two guide bars 105 gradually increases in the direction of the opening of the docking area 101 to better guide the material frame 4 into the traction flatbed truck.

[0042] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, a frame 6 for connecting the support plate 1 and the wheel 2 is also included, on which a traction assembly 3 for connecting a tractor is connected.

[0043] Specifically, the frame 6 is fixed to the bottom of the load-bearing plate 1 to bear the load and transfer it to the wheels 2. The tractor acts on the frame 6 through the traction component 3, thereby driving the entire tractor flatbed to move. The frame 6 can be two independent parts set at the bottom of the two side plates 103, or it can be formed into an integral frame by setting a connecting frame at the bottom of the connecting plate 104.

[0044] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the traction assembly 3 includes a rotating shaft 303 connected to the frame 6 and extending perpendicular to the traction direction, a traction rod 301 rotatably connected to the frame 6 via the rotating shaft 303, and a spare tow hook 304 disposed on the other side of the frame 6 opposite to the traction rod 301.

[0045] Specifically, to avoid interference between the tractor and the lurking guide vehicle 5, the towing rod 301 and the spare towing hook 304 are respectively set on the side of the two side plates 103 away from the docking area 101. One end of the towing rod 301 is connected to the frame through the rotating shaft 303, and the other end is provided with a connecting hole 302 for connecting the tractor. By setting the towing rod 301 and the spare towing hook 304 on opposite sides of the tractor, the traction of the tractor can be changed more conveniently.

[0046] In some embodiments, such as Figure 5As shown, the rotating shaft 303 is connected to the position where the frame 6 extends out of the bearing plate 1, so that the towing rod 301 can rotate to a vertical position to be close to the canopy 8 of the towing flatbed, reducing the space occupied by the towing flatbed.

[0047] like Figure 6 and Figure 7 As shown, in some embodiments, a weighing sensor 7 is provided between the support plate 1 and the wheel 2.

[0048] Specifically, the load-bearing plate 1 transfers the load to the frame 6 through the weighing sensor 7. When the frame 6 is composed of two parts of the frame respectively set at the bottom of the two side plates 103, two weighing sensors 7 are set accordingly to obtain the weight of the material on the traction flatbed, so as to facilitate the monitoring of the material on the flatbed.

[0049] In some embodiments, the traction flatbed is also equipped with an automatic calling system, including a weighing sensor 7, a locator, a control module, and a signal transmitter. The weighing sensor 7 is used to monitor the material condition on the flatbed, the locator is used to determine the moving position of the traction flatbed, and the control module is used to receive signals from the weighing sensor 7 and the locator and send a command to the signal transmitter when the transfer conditions are met. The signal transmitter sends a calling signal to the steered guided vehicle 5 to call the steered guided vehicle 5 to perform material transfer operations, which effectively improves the efficiency of material transfer.

[0050] like Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, a canopy 8 is provided on the support plate 1. Providing a canopy 8 to cover the material on the support plate 1 allows the tractor flatbed to be used in outdoor environments, improving its applicability.

[0051] In some embodiments, the wheel 2 is provided with a lockable brake pad.

[0052] Specifically, after the traction flatbed is moved to the designated position, the wheels 2 are locked by the brake pads to prevent the flatbed from shifting during the docking process of the submersible guide car 5, which would cause the material frame 4 to deviate. After the material frame 4 is placed, the brake pads are unlocked to continue transferring materials.

[0053] This utility model also provides a material transfer system, including a material frame 4 for holding materials, a submersible guide vehicle 5 for transporting the material frame 4, and the aforementioned traction flatbed vehicle, wherein the width of the docking area 101 is greater than the width of the submersible guide vehicle 5 and less than the width of the material frame 4.

[0054] Specifically, when using the material transfer system of this utility model for transfer operations, the submersible guide vehicle 5 first lifts the material frame 4 to a position higher than the support plate 1. Since its own width is less than the width of the docking area 101, it can smoothly drive into the docking area 101 and make the material frame 4 located above the support plate 1. After reaching the designated position, by lowering its own lifting device, the material frame 4, which is wider than the docking area 101, is lowered and placed on the support plates 1 on both sides of the docking area 101, thereby completing the transfer of materials.

[0055] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions described herein based on the above description.

Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of the present invention.
