[0039] With the rapid development of the modern logistics industry towards automation and intelligence, smart warehousing applications are becoming increasingly widespread.

[0040] In warehousing systems that store large workpieces and other heavy objects, the heavy objects are often placed on pallets, and then manually driven forklifts are used to pick up the pallets and transport them to the designated workstations.

[0041] However, this method of manually driving forklifts to transport heavy objects is labor-intensive, has low transport stability and reliability, and places high demands on the forklift's load capacity. To reduce labor costs and improve the efficiency and stability of heavy object transport, this application provides a heavy-duty RGV and warehousing system. The following will describe in detail the solution provided by the embodiments of this application with reference to the accompanying drawings.

[0042] Figure 1 This is a schematic diagram of the overall structure of a heavy-duty RGV provided in an embodiment of this application; Figure 2 yes Figure 1 Internal structure diagram of the heavy-duty RGV in the diagram; Figure 3 yes Figure 1 A top view of the heavy-load RGV in the image.

[0043] Reference Figures 1 to 3As shown, this application embodiment provides a heavy-duty RGV, including a frame 100, a traveling assembly, and a heavy-duty conveying assembly 300. The frame 100 can be a frame structure, serving as the mounting base for various components. The traveling assembly is mounted on the frame 100 and contacts a track to drive the frame 100 to move along the track. The heavy-duty conveying assembly 300 is mounted on the frame 100 and used to move heavy objects onto the frame 100. Specifically, the heavy-duty conveying assembly 300 includes a conveying frame 310, multiple conveying rollers 320, and a conveying drive assembly 330. The conveying frame 310 is a rectangular support frame structure. The conveying frame 310 is fixedly mounted on the frame 100, and the multiple conveying rollers 320 are spaced apart on the conveying frame 310 and interconnected via synchronous chains or synchronous belts or other transmission components. A conveyor drive assembly 330 is mounted on the frame 100 and connected to at least one conveyor roller 320, thereby enabling the conveyor drive assembly 330 to drive all conveyor rollers 320 to rotate. When the conveyor drive assembly 330 drives all conveyor rollers 320 to rotate, heavy objects can be conveyed onto the frame 100. Then, the travel assembly actuates, driving the frame 100 to move along the track, thereby moving the heavy objects on it to a designated location. Compared to the prior art of manually driving forklifts to transport heavy objects, this heavy-duty RGV can automatically transport heavy objects along the track without manual intervention and with higher efficiency. For example, the conveyor drive assembly 330 can be a servo drive motor, which is connected to one conveyor roller 320 via a synchronous chain, and adjacent conveyor rollers 320 are connected by synchronous chains.

[0044] Reference Figure 1 and Figure 2 As shown, the portions of the conveyor frame 310 located at both ends of the conveyor roller 320 protrude from the conveying surface of the conveyor roller 320 and extend along the conveying direction. When the conveyor roller 320 conveys heavy objects, the protruding portions of the conveyor frame 310 can limit the heavy objects located on the conveyor roller 320, preventing them from deviating from the conveying direction and falling off the conveyor roller 320.

[0045] For example, in some examples, each conveying roller 320 includes two support rollers 321 and an intermediate roller 322. The two support rollers 321 are coaxially disposed at both ends of the intermediate roller 322, and the two support rollers 321 are rotatably connected to the frame 100. The conveying surface of the support rollers 321 is higher than that of the intermediate roller 322, and they are used to support heavy objects. That is, the diameter of the intermediate roller 322 is smaller than the diameter of the support rollers 321, and the two are fixed together coaxially. Since the intermediate roller 322 connects the two support rollers 321 together, the bearing strength of the two support rollers 321 connected to the conveying frame 310 is improved, thereby enabling them to support heavier objects.

[0046] The walking components are provided in at least two sets, each set corresponding to at least two walking tracks. Each set of walking components includes at least two walking wheels 200, and each set is equipped with at least one walking drive component 900 to drive the walking wheels 200 to move on the walking tracks. For example, as shown... Figure 3 As shown, in some examples, two sets of traveling components are provided, spaced apart along the traveling direction of the frame 100. Each set of traveling components includes two traveling wheels 200, each corresponding to a traveling track. Furthermore, at least one of the two traveling wheels 200 in each set is equipped with a traveling drive component 900 to ensure that the two sets of traveling components can drive the frame 100 to move stably along the traveling track. Exemplarily, the traveling wheels 200 can be fixedly mounted on the frame 100 via bearing seats, and the traveling drive component 900 can be configured as a traveling drive motor to drive the traveling wheels 200 to rotate.

[0047] Understandably, at least two wheels 200 connected to the walking drive assembly 900 serve as power sources to drive the frame 100 to move, while the other two wheels 200 serve as driven components.

[0048] In some examples, the heavy object conveying assembly 300 further includes at least one heavy object limiting assembly 400, which is disposed at the end of the conveying frame 310 and selectively protrudes from the conveying surface to limit the sliding of the heavy object on the support roller 321 along the conveying direction. That is, the heavy object limiting assembly 400 is used to limit the heavy object on the support roller 321 to prevent it from sliding off the support roller 321 in the conveying direction during the conveying process.

[0049] like Figure 2 As shown in this embodiment, the heavy object conveying assembly 300 is provided with two heavy object limiting assemblies 400, which are located at both ends of the conveying frame 310 along the conveying direction. When a heavy object is conveyed onto the conveying frame 310, the two heavy object limiting assemblies 400 protrude from the conveying surface, restricting the movement of the heavy object at both ends of the conveying direction of the conveying frame 310, thereby preventing the heavy object from slipping off the conveying frame 310.

[0050] For example, in some examples, the weight limiting assembly 400 includes a limiting post 420 and a lifting drive mechanism for driving the limiting post 420 to rise and fall. The limiting post 420 is connected to the lifting drive mechanism, which can drive the limiting post 420 to selectively rise and fall to limit the weight. For example, the lifting drive mechanism can be one of the following: electric cylinder, pneumatic cylinder, hydraulic cylinder, gear and rack structure, lever structure, or cam structure. As long as it can drive the limiting post to rise and fall, it is acceptable. These are all prior art and will not be described in detail here.

[0051] In other examples, the weight limiting assembly 400 includes a limiting post 420 and a flipping drive mechanism. The flipping drive mechanism is connected to one end of the limiting post 420 and is used to drive the limiting post 420 to flip so that the limiting post 420 can protrude from the conveying surface of the weight conveying assembly 300. Exemplarily, the flipping drive mechanism can be a servo motor or a linkage mechanism with a drive source, as long as it can make the limiting post swing or flip. These are all prior art and will not be described in detail.

[0052] Continue to refer to Figure 2 As shown, in some examples, the weight limiting assembly 400 includes a limiting seat 410, a limiting post 420, a hinge seat 430, a connecting rod 440, and a linear drive component 450. The limiting seat 410 is mounted on the conveyor frame 310 and has a vertically extending limiting hole, in which the limiting post 420 is fitted. One end of the connecting rod 440 is hinged to the limiting post 420, and the other end is hinged to the linear drive component 450, which is vertically mounted on the conveyor frame 310. The hinge seat 430 is mounted on the conveyor frame 310, and the connecting rod 440 is hinged to the hinge seat 430 at its midpoint. The linear drive component 450 is used to drive the limiting post 420 to selectively protrude from the conveyor surface via the connecting rod 440. Specifically, when the linear drive component 450 drives the connecting rod 440 to rise in height, the limiting post 420 moves downward under the action of the connecting rod 440 and eventually hides below the conveying surface of the support roller 321; conversely, when the linear drive component 450 drives the connecting rod 440 to fall in height, the limiting post 420 moves upward under the action of the connecting rod 440 and eventually extends above the conveying surface of the support roller 321 to block the movement of heavy objects on the conveying surface and prevent heavy objects from falling during movement.

[0053] In other examples, the weight limiting assembly 400 includes a baffle plate and a linear drive component 450. The linear drive component 450 is vertically mounted on the conveyor frame 310, and the baffle plate is fixedly mounted on the movable end of the linear drive component 450. The linear drive component 450 drives the baffle plate to protrude from the conveyor surface or hide below the conveyor surface.

[0054] For example, the linear drive component 450 may be a cylinder, hydraulic cylinder, electric cylinder or other linear drive component.

[0055] like Figure 1 As shown, in some examples, the heavy-duty RGV also includes a cover plate 500, which is disposed on the conveyor frame 310, above the intermediate rollers 322, and the support rollers 321 protrude from the cover plate 500. The cover plate 500 shields the intermediate rollers 322, preventing debris from falling between the intermediate rollers 322 and avoiding interference with the support rollers 321 in conveying heavy objects. Exemplarily, the cover plate 500 may be a sheet metal part.

[0056] The electrical control box 600 of the heavy-duty RGV is mounted on the frame 100 and located on both sides of the heavy-duty conveying assembly 300. The electrical control box 600 houses the electrical control components, which are electrically connected to the travel drive assembly 900, the conveying drive assembly, and other electrical components via wires. These components control the movement of the travel wheels 200 and the heavy-duty conveying assembly 300. Additionally, in some examples, each electrical control box 600 is equipped with a sliding door 610. The sliding door 610 allows for easy opening of the electrical control box 600 and convenient maintenance of the internal electrical control components.

[0057] like Figure 1 As shown, the heavy-duty RGV also includes a first detection component 700, which is disposed on the conveyor frame 310. The first detection component 700 is horizontally oriented towards the outside of the conveyor frame 310. The first detection component 700 can be used for obstacle avoidance detection to avoid collisions with other obstacles, and can also be used for real-time relative position detection to detect whether there is any deviation during travel.

[0058] In addition, in some examples, the heavy-duty RGV also includes a second detection component 800, which is disposed on the conveyor frame 310 and is vertically upward, to detect the position of the heavy object and determine whether the heavy object has moved to the designated position of the conveyor frame 310.

[0059] Secondly, embodiments of this application provide a warehousing system including a heavy-duty RGV as described in any of the first aspects, the heavy-duty RGV being used to transport heavy objects along a track.

[0060] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.

It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
