[0037] Example

[0038] Please see Figure 1As shown, this embodiment provides a material handling trolley 1 suitable for intelligent handling robots, including a trolley body 1-1 and wheels 1-2 located at the bottom of the trolley body 1-1. The wheels 1-2 include directional wheels 1-21 and omnidirectional wheels 1-22, with the directional wheels 1-21 located at the front bottom of the material handling trolley 1 and the omnidirectional wheels 1-22 located at the rear bottom of the material handling trolley 1. The trolley body 1-1 is rectangular pallet type, including a rectangular frame 1-11 and a base plate 1-12.

[0039] In this embodiment, the inner dimensions of the material transfer trolley 1's body 1-1 can be adapted to the dimensions of one or more turnover boxes 2, so that the turnover boxes can be stably placed on the body 1-1 without requiring additional fixing of the turnover boxes 2 to the material transfer trolley 1. Figure 13 As shown; however, it should be noted that although this embodiment takes the inner cavity size of the vehicle body 1-1 as an example that is adapted to the size of a turnover box 2, it is not limited to this size design. The inner cavity size can also be adapted to the length and width of 2N (N is a natural number) material turnover boxes 2 placed side by side, so that a material transfer trolley 1 can transfer multiple turnover boxes 2 at one time, thereby greatly improving the turnover efficiency.

[0040] Please combine Figures 1 to 4 As shown, in this embodiment, each wheel 1-2 of the material transfer trolley 1 is detachably connected to the base plate 1-12 via a wheel fixing seat 1-23. Specifically, in this embodiment, a bolt hole 1-231 is provided at the top center of each wheel fixing seat 1-23, and a wheel fixing bolt hole 1-121 is provided on the base plate 1-12 at the corresponding position. Each wheel 1-2 can be detachably connected to the base plate 1-12 by passing a bolt through the bolt hole 1-231 and the wheel fixing bolt hole 1-121.

[0041] As a preferred embodiment, several limiting blocks 1-24 are provided on the top front or rear side of the wheel mounting base 1-23. By providing several limiting blocks 1-24 on the top front or rear side of the wheel mounting base 1-23, it is not only beneficial to quickly install and position the wheel mounting base 1-23, but also to ensure that the wheel 1-2 can be fixed by a single central bolt under the blocking action, thus making the replacement and disassembly of the wheel 1-2 very convenient.

[0042] Please see again. Figure 1 and Figure 2As shown, in this embodiment, L-shaped protrusions 1-13 are provided at the opposing positions of each right angle of the base plate 1-12. The two sides of each right angle and the opposing protrusions 1-13 form a wheel stacking limiting area 1-14. By setting the wheel stacking limiting area 1-14, the wheels 1-2 of the material transfer trolley 1 can be limited within the wheel stacking limiting area 1-14 when the material transfer trolley 1 is stored and stacked. Please refer to [link to relevant documentation]. Figure 5 As shown, the material transfer trolley 1 described in this utility model is designed to facilitate easy storage and stacking, which can significantly reduce the space occupied by storage.

[0043] Please see again. Figure 1 and Figure 2 As shown, in this embodiment, symmetrical through holes 1-122 are provided at the front and rear of the base plate 1-12. A trolley assembly A 1-15 is fixed at the bottom of one through hole, and a trolley assembly B 1-16 is rotatably connected to the bottom of the other through hole. A gourd-shaped through hole 1-151 is provided at the center of the trolley assembly A 1-15, with the smaller end of the gourd-shaped through hole 1-151 facing outward and the larger end facing inward. A traction hook 1-17 is vertically fixed on the inner wall of the free end of the trolley assembly B 1-16. The traction hook 1-17 can be hooked with the small hole 1-1511 of the gourd-shaped through hole 1-151 (see [link]). Figure 12 As shown in the figure, multiple material transfer carts 1 can be spliced ​​and connected.

[0044] Please combine Figure 1 and Figure 12 As shown, in this embodiment, the traction hook 1-17 is a T-shaped stud. The diameter of the stud body 1-171 is smaller than the diameter of the small hole 1-1511 of the gourd-shaped through hole 1-151, and the diameter of the stud head 1-172 is larger than the diameter of the small hole 1-1511 of the gourd-shaped through hole 1-151 and smaller than the diameter of the large hole 1-1512 of the gourd-shaped through hole 1-151. This allows the stud body 1-171 to pass through the small hole 1-1511 of the gourd-shaped through hole 1-151, while the stud head 1-172 is located outside the small hole 1-1511 of the gourd-shaped through hole 1-151, thereby achieving the connection function of hooking.

[0045] Please combine Figures 6 to 8 As shown, in this embodiment, the trolley splicing component A 1-15 is a U-shaped plate, with a gourd-shaped through hole 1-151 opened at the bottom of the U-shaped plate. One side arm of the U-shaped plate is fixedly connected to the rectangular frame 1-11, and the other side arm of the U-shaped plate is fixedly connected to the folded edge 1-122 opened on the base plate 1-12.

[0046] Please see again. Figures 9 to 11As shown, in this embodiment, the trolley splicing component B 1-16 is an L-shaped plate, the traction hook 1-17 is vertically fixed on the inner wall of the free end of the vertical arm 1-161 of the L-shaped plate 1-16, and the far end of the horizontal arm 1-162 of the L-shaped plate 1-16 is fixedly connected to the bottom of the elastic rotating member 1-18. The elastic rotating component 1-18 includes a bushing 1-181, a torsion spring 1-182, and an arc-shaped fixing frame 1-183. The torsion spring 1-182 is sleeved on the bushing 1-181, and one end of the torsion spring 1-182 is fixedly connected to the bushing 1-181. The other end of the torsion spring 1-182 is fixedly connected to the top of the arc-shaped fixing frame 1-183. The two sides of the arc-shaped fixing frame 1-183 are fixedly connected to the inner sidewall of the rectangular frame 1-11. The bushing 1-181 is installed in the cavity of the arc-shaped fixing frame 1-183 by bolts 1-184. The distal end of the transverse arm 1-162 of the L-shaped plate 1-16 is fixedly connected to the bottom of the bushing 1-181.

[0047] Please see Figure 12 As shown, when it is necessary to connect the trolley assembly component B 1-16 on one trolley to the trolley assembly component A 1-15 on another trolley, simply rotate the trolley assembly component B 1-16 manually so that its vertical arm 1-161 is in a horizontal inverted state. This allows the traction hook 1-17 located on the inner wall of the free end of the vertical arm 1-161 to be in a vertically upward state. It can then enter through the large hole 1-1512 of the gourd-shaped through hole 1-151 at the bottom of the trolley assembly component A 1-15 on the other trolley, and hook into the small hole 1-1511 of the gourd-shaped through hole 1-151 to achieve the connection between the two. Because a torsion spring 1-182 is provided at one end of the bushing 1-181, the upward restoring force of the torsion spring 1-182 ensures that the traction hook 1-17 and the gourd-shaped through hole 1-151 can be securely connected and will not fall off.

[0048] As can be seen from the above, the material transfer trolley described in this utility model allows for the direct and stable stacking of turnover boxes on the trolley body without additional fixing, significantly saving manpower and resources, greatly reducing the labor intensity of relevant personnel, significantly improving logistics efficiency, and reducing potential safety risks. Furthermore, this utility model allows for the stable stacking and storage of multiple trolleys, saving storage space. In addition, the material transfer trolley described in this utility model allows for convenient splicing and wheel replacement. In conclusion, through its ingenious structural design, this utility model enables the material transfer trolley to well meet various needs, and is of great significance and industrial application value in improving the efficiency of AGV automated handling.

[0049] Finally, it should be pointed out that the above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
