In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] The following will elaborate on the track assembly disclosed by the present utility model in conjunction with the drawings. As shown in the attached Figure 1 figure, it includes a frame 100, on which an upper closed track 200 is provided. The upper closed track 200 includes a C-shaped roller groove 210 with its notch facing downwards. A first lower track 300 and a second lower track 400 which are concentric with and located below the upper closed track 200 are also provided on the frame 100. The first lower track 300 and the second lower track 400 are at the same height, and the first lower track 300 surrounds the outer periphery of the second lower track 400.

[0029] As shown in the attached Figure 1 and attached Figure 2 figures, the frame 100 includes a top frame 110 and a bottom frame 120, which are connected by a set of connecting frames 130. The structures of the top frame 110, the bottom frame 120 and the connecting frames 130 can be designed according to needs. For example, in this embodiment, the top frame 110 is assembled by multiple cross beams and longitudinal beams, the structure of the bottom frame 120 is the same as that of the top frame 110, the connecting frame 130 is at least one square frame, and at the same time, adjacent connecting frames 130 are connected by steel cables 140 distributed in an X shape. Preferably, adjacent connecting frames 130 are connected by two pairs of steel cables 140 distributed in an X shape, which can effectively ensure the stability of the overall structure. To facilitate the movement of the frame 100, a set of universal wheels 150 with a known locking structure are provided at the bottom of the frame 100, and details are not elaborated here.

[0030] The shape of the upper closed track 200 can be designed as required. Generally, it is set as a kidney shape. Of course, it can also be other feasible shapes, which are not limited here. At the same time, the track is arranged at the bottom of the top frame 110.

[0031] As shown in the Figure 3 attachment, the shapes of the first lower track 300 and the second lower track 400 are adapted to the shape of the upper closed track 200. When the upper closed track 200 is kidney-shaped, they are also designed as kidney-shaped. The distance between the first lower track 300 and the second lower track 400 can be designed as required, which is not designed here. At the same time, the distances from the upper closed track 200 to the first lower track 300 and the second closed track are the same, which is conducive to enabling the sorting trolley rolling on the upper closed track 200, the first lower track 300 and the second lower track 400 to maintain a better stable state.

[0032] As shown in the Figure 2 attachment, Figure 4 the first lower track 300 and the second lower track 400 are arranged on the bottom frame 120. The first lower track 300 and the second lower track 400 both include a U-shaped groove 001, and the openings of the two U-shaped grooves 001 are arranged opposite to each other. And, in order to facilitate the connection with the bottom frame 120, the first lower track 300 and the second lower track 400 further include vertical limiting plates 002 connected to the lower sides of their supporting plates. The vertical limiting plates 002 can cooperate with the limiting wheels on the sorting trolley to limit the horizontal position of the sorting trolley. At the same time, the first lower track 300 and the second lower track 400 are respectively connected to the bottom frame 120 through U-shaped connectors 500 located on their outer sides. The openings of the U-shaped connectors 500 face away from the vertical limiting plates 002. Thus, the middle vertical plate of the U-shaped connector 500 is screwed to the vertical limiting plate 002. At the same time, the upper plate of the U-shaped connector 500 can effectively support the bottom plate of the U-shaped groove 001, and the lower plate of the U-shaped connector 500 is connected to the bottom frame 120.

[0033] As shown in the Figure 1 attachment, Figure 4 for the convenience of processing and assembly, the first lower track 300 and the second lower track 400 are respectively assembled by a plurality of track segments 003 in sequence. The ends of adjacent track segments 003 are connected through the U-shaped connectors 500. In order to ensure the stability of the connection of the track segments 003, each U-shaped connector 500 is connected to a limiting block 600. A clamping groove is arranged at the bottom of the limiting block 600, and the clamping groove is clamped on the limiting plate 700 on the bottom frame 120. Thus, the bolts connecting the U-shaped connector 500 and the track segment 003 will not be subjected to shear force, and the stability of the connection can be ensured. And the inner sides of adjacent track segments 003 are connected through a connecting plate 004.

[0034] As shown in the Figure 2 accompanying drawings, in order to facilitate power supply, a sliding contact wire power supply rail 800 is provided on the inner side surface of the vertical limit plate 002 of the first lower rail 300 or the vertical limit plate 002 of the second lower rail 400.

[0035] As shown in the Figure 2 accompanying drawings, a primary 900 of a linear motor is further provided on the chassis 120 and located between the first lower rail 300 and the second lower rail 400.
