Description

Technical Field

[0001] The utility model relates to the technical field of logistics warehousing, in particular to a chain-type RGV cart. Background Art

[0002] RGV is the English abbreviation of Rail Guided Vehicle, also known as a rail-guided shuttle cart. In the logistics warehousing industry, the application of RGV carts is very common and is commonly used in the conveying system at the input and output ends of intelligent warehouses. It can effectively connect the conveying lines, especially for long-distance conveying. The existing RGV carts have relatively single functions. Generally, a single cart can only convey pallets of one width specification and it is difficult to accommodate pallets of two width specifications, resulting in a narrow scope of application. Especially in large warehouses where the pallet specifications are not unified, in order to facilitate the planning of the conveying system, the side guards of the chain conveying line can only be made electrically adjustable, resulting in a larger body size, a complex structure, and a high failure rate.

Specific embodiments

[0030] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1-6, an embodiment of the present application discloses a chain - type RGV cart, which includes a vehicle body 1, a first conveying component, a second conveying component, and a baffle component. The first conveying component is arranged on the vehicle body 1, and the first conveying component includes two first chain conveying lines 2 symmetrically arranged along the horizontal direction. The second conveying component is arranged on the vehicle body 1, and the second conveying component includes two second chain conveying lines 3 symmetrically arranged along the horizontal direction. The two second chain conveying lines 3 are located between the two first chain conveying lines 2, and the first conveying surface 21 of the two first chain conveying lines 2 is higher than the second conveying surface 31 of the second chain conveying lines 3. The baffle component is arranged on the vehicle body 1, and the baffle component includes two baffle members 4 symmetrically arranged along the horizontal direction. The two first chain conveying lines 2 are located between the two baffle members 4.

[0032] In the present utility model, the two first chain conveying lines 2 and the two second chain conveying lines 3 share the same vehicle body 1. By making a height difference between the first chain conveying line 2 and the second chain conveying line 3, the transportation of trays of two width specifications can be realized, and the structure is simple. The conveying frame 22 of the first chain conveying line 2 can be used as a stop portion for small - width trays conveyed on the two second chain conveying lines 3, and this stop portion does not need to be set separately. The two baffle members 4 provided are used as stop edges for large - width trays conveyed on the two first chain conveying lines 2. This stop edge has a simple structure, occupies little space, is convenient to install, and has good stop stability.

[0033] Preferably, the baffle member 4 includes at least two support frames 41 and a baffle 42 connected to the at least two support frames 41. The height of the baffle 42 can be adjusted by adjusting the height of the support frame 41. The support frame 41 is convenient to process and reduces costs. The two symmetrically arranged baffle members 4 are used to stop large - width trays to prevent the large - width trays from slipping off the first chain conveying line 2. In this embodiment, preferably, the number of support frames 41 of each baffle member 4 is three.

[0034] Please refer to Figure 2 , the support frame 41 includes an inverted L - shaped plate and a reinforcing plate 411. The inverted L - shaped plate includes a horizontal plate 412 and a vertical plate 413, and the reinforcing plate 411 is respectively connected to the horizontal plate 412 and the vertical plate 413.

[0035] Preferably, the horizontal plate 412 and the vertical plate 413 are an integrally formed bent structure, and the reinforcing plate 411 is respectively welded to the horizontal plate 412 and the vertical plate 413 to improve the overall strength and stability of the support frame 41.

[0036] Preferably, the ends of the two baffles 42 form a flared shape with a larger outer and a smaller inner diameter, so as to form a guiding setting, enabling the trays on the two first chain conveying lines 2 to smoothly enter and leave the two first chains 2, thereby improving the conveying efficiency.

[0037] Please refer to Figure 1 、Figure 2 The retaining edge 42 includes a base plate 421, a vertical baffle 422 connected to the base plate 421, and an inclined baffle 423 connected to the vertical baffle 422. The base plate 421 is horizontally arranged, the vertical baffle 422 is vertically arranged, and the inclined baffle 423 is inclined outward. The horizontal arrangement of the base plate 421 can be more stably installed on the support frame 41. The vertical arrangement of the vertical baffle 422 can better stop and provide horizontal guidance. The inclined baffle 423 inclined outward is used to provide vertical guidance, which is convenient for manual forklifts to directly place goods.

[0038] To facilitate the installation of the base plate 421 on the support frame 41, preferably, a plurality of mounting holes 4211 are provided on the base plate 421. Specifically, the base plate 421 is fixed on the horizontal plate 412 of the support frame 41.

[0039] By sharing the vehicle body 1 of an RGV trolley, the first chain conveyor line 2 and the second chain conveyor line 3 are arranged in a structure with a height difference, so that the transportation of two types of pallets with different widths can be realized. The large-width pallet is set as the first pallet 5, and the small-width pallet is set as the second pallet 6. In the figure, the width of the first pallet 5 shown as an example is 1400 mm, and the width of the second pallet 6 is 1200 mm. It can be understood that the widths of the first pallet 5 and the second pallet 6 are not limited to those shown as examples and can be set according to requirements. Please refer to Figure 1 This is the state where the first pallet 5 enters the RGV trolley. At this time, the first pallet 5 is located on the first conveying surface 21 of the two first chain conveyor lines 2. Please refer to Figure 4 This is the state where the second pallet 6 enters the RGV trolley. At this time, the second pallet 6 is located on the second conveying surface 31 of the two second chain conveyor lines 3. Please refer to Figure 5 、 Figure 6 At this time, the first pallet 5 is located on the first conveying surface 21 of the two first chain conveyor lines 2 and carries a load 7.
