Description

Technical Field

[0001] This utility model relates to the field of automated logistics technology, specifically a novel conveying RGV. Background Technology

[0002] In automated logistics systems, rail-guided vehicles (RGVs) are important material handling equipment and are widely used in various production lines, warehouses, and logistics centers. Traditional RGV designs often focus on meeting basic material handling needs, with relatively simple vehicle structures, limited load-bearing capacity, and fixed conveyor modules, making it difficult to adapt to diverse conveyor line docking requirements.

[0003] With the continuous improvement of industrial automation, higher requirements are being placed on the performance of RGVs. Especially in scenarios that require docking with different conveyor lines, carrying large loads, or transporting items of various shapes, the design limitations of traditional RGVs are becoming increasingly apparent. On the one hand, the stability and load-bearing capacity of the vehicle body structure have become key factors restricting the application range of RGVs; on the other hand, the flexibility of the conveying modules is insufficient, making it difficult to meet diverse material handling needs. Utility Model Content

[0004] Therefore, this utility model provides a novel transport RGV to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel transport RGV, characterized in that it includes a vehicle body, active traveling wheels, driven traveling wheels, an outer shell, and a transport module;

[0006] The vehicle body is configured as a frame structure made of hot-formed steel. Several sets of active and passive wheels are installed at the bottom of the vehicle body and are distributed diagonally. The outer shell is fixedly installed on the upper part of the vehicle body. The conveying module is installed on the top of the outer shell and can drive the movement of goods.

[0007] Furthermore, the active walking wheel includes a first base, a second base, a walking wheel, a first motor, and a guide wheel;

[0008] The first seat is installed at the bottom of the vehicle body, and the bottom end of the second seat is rotatably connected to the first seat; the walking wheel is rotatably connected inside the second seat and driven by the first motor, and the guide wheel is rotatably connected to the bottom of the second seat to provide guidance support when walking on the track.

[0009] Furthermore, the driving end of the first motor is connected and fixed to the driven end of the walking wheel, and the bottom of the walking wheel protrudes from the lower surface of the second seat.

[0010] Furthermore, a reserved work position is provided on the top of the outer shell, and the conveying module is installed and fixed inside the reserved work position.

[0011] Furthermore, the conveying module includes a frame, a support, a conveying roller, a driven sprocket, a second motor, and a driving sprocket;

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 5 As shown, a novel conveying RGV according to the first aspect embodiment of this utility model includes a body 1. The body 1 is set as a frame structure made of hot-formed steel, which makes the entire RGV more stable during use and greatly improves its load-bearing capacity. Several sets of active walking wheels 2 and driven walking wheels 3 are respectively installed at the bottom of the body 1. An outer shell 4 is installed and fixed on the upper part of the body 1. A conveying module 5 is installed and fixed on the top of the outer shell 4. According to actual needs, different types of conveying modules 5 are set on the top of the outer shell 4, which enables the RGV to be compatible with different conveying lines.

[0026] Several sets of active walking wheels 2 and driven walking wheels 3 are diagonally distributed at the bottom of the vehicle body 1. This makes the force on the vehicle body more even when the active walking wheels 2 drive the RGV to walk along the track. The difference between the active walking wheels 2 and the driven walking wheels 3 is that the active walking wheels 2 are driven by the first motor 24, while the driven walking wheels 3 are not equipped with the first motor 24. The other structures are exactly the same.

[0027] The active walking wheel 2 includes a first seat 21 installed at the bottom of the vehicle body 1. The bottom end of the first seat 21 is rotatably connected to a second seat 22. The interior of the second seat 22 is rotatably connected to a walking wheel 23. A first motor 24 is installed and fixed on the side of the second seat 22. The driving end of the first motor 24 is connected and fixed to the driven end of the walking wheel 23. The bottom of the walking wheel 23 protrudes from the lower surface of the second seat 22. Several guide wheels 25 are rotatably connected to the bottom of the second seat 22. When the RGV is driven to walk on the track by the active walking wheel 2, the first motor 24 drives the walking wheel 23 to rotate. Thus, the RGV can walk along the track by relying on the friction generated between the RGV's own weight and the track. Because the first seat 21 and the second seat 22 can rotate relative to each other, and several guide wheels 25 abut against both sides of the track, the active walking wheel 2 can make adaptive steering adjustments when encountering curved sections of the track.

[0028] A reserved workstation 41 is provided on the top of the outer shell 4. The conveying module 5 is installed and fixed inside the reserved workstation 41. The specific conveying module 5 includes a frame 51 installed inside the reserved workstation 41 and a bracket 52 installed and fixed inside the vehicle body 1. Several conveying roller shafts 53 are rotatably connected inside the frame 51. The several conveying roller shafts 53 are laid out in a plane inside the frame 51. A driven sprocket 54 is installed at the end of each conveying roller shaft 53. A second motor 55 is installed inside the bracket 52. A drive sprocket 56 is installed at the drive end of the second motor 55. The driven sprocket 54 and the drive sprocket 56, as well as two adjacent driven sprockets 54, are connected by a chain (the chain is not shown in the figure. The specific connection structure between the chain, the drive sprocket 56, and the driven sprocket 54 is existing known technology and will not be described in detail here). Specifically, the driven sprocket 54 is set as a double-row sprocket, and the drive sprocket 56 is set as a single-row sprocket.

[0029] When the RGV is in operation, it is positioned above the two tracks 6. At this time, the inner side of the symmetrically arranged guide wheels 25 will abut against the two sides of the tracks 6, so that the RGV is not easy to derail when it moves. During the movement, it is driven by the active walking wheel 2, and the driven walking wheel 3 serves as the driven support structure. When it needs to connect to the conveyor line, assuming that the RGV needs to be loaded, then the RGV connects to the outlet of the conveyor line. The goods to be transferred arrive at the conveyor module 5 from the outlet of the conveyor line. Then, the second motor 55 drives the active sprocket 56 to rotate, and then drives the driven sprocket 54 and the conveyor roller shaft 53 to rotate as a whole through the chain, so that the goods are transported.

[0030] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0031] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
