Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a reversing structure and a shelf for a four-way shuttle vehicle. Background Art

[0002] During the operation of shuttle racks, in order to improve the overall logistics transportation and storage efficiency and reduce transportation costs, multiple main aisles are usually added to this type of rack for the four-way shuttle vehicles used to transport goods. On both sides of each main aisle are sub-aisles for storing goods. The four-way shuttle vehicles switch from the main aisle to the sub-aisle through the track reversing structure to realize the transportation and storage and retrieval of goods.

[0003] Existing track switching methods typically install U-shaped pieces on either side of the main channel, then place rectangular steel bars inside the two U-shaped pieces, with the rectangular steel bars serving as the switching track. Because the rectangular steel bars only contact the U-shaped pieces at their two ends, leaving the middle section (which is much longer than the sum of the two ends) suspended in the air, this switching structure presents issues such as unstable switching tracks and the tendency for four-way shuttles to wobble when transporting cargo on the rectangular steel bars.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0025] Combine Figures 1 to 3 As shown, the reversing structure for the four-way shuttle 40 of this embodiment includes a support rod 1, a reversing track 2, a first transition track 3, and a second transition track 4. The support rod 1 is used to connect to the shelf, the reversing track 2 is mounted on the support rod 1, the first transition track 3 is mounted on the support rod 1 and located at one end of the reversing track 2, and the second transition track 4 is mounted on the support rod 1 and located at the other end of the reversing track 2. A predetermined distance is set between the end of the first transition track 3 and the end of the reversing track 2, so that the first transition track 3, the reversing track 2, and the support rod 1 collectively form a first accommodating space 32. A predetermined distance is also set between the end of the second transition track 4 and the end of the reversing track 2, so that the second transition track 4, the reversing track 2, and the support rod 1 collectively form a second accommodating space 42.

[0026] Specifically, if Figure 3 As shown, the shelf of this embodiment is basically the same as the existing shelf in that it includes multiple horizontal beams. These beams constitute the main structure of the shelf and are used to support the goods. There is a first beam 10 closest to the main channel and a second beam 20 closest to the other side of the main channel. The two ends of the support rod 1 of the reversing structure are connected to the first beam 10 and the second beam 20 respectively. Figure 2 As shown, after the reversing structure is installed on the shelf, the support rod 1 is located below the main channel track 30, and the main channel track 30 is located in the first accommodating space 32 and the second accommodating space 42. The first transition track 3 is used to connect the reversing track 2 and the sub-channel located on the side of the first crossbeam 10, and the second transition track 4 is used to connect the reversing track 2 and the sub-channel located on the side of the second crossbeam 20.

[0027] Combine Figure 1 and Figure 2As shown, the two ends of the support rod 1 of this embodiment are respectively connected to a first connecting member 5, and the first connecting member 5 is provided with a waist-shaped hole 51. One end of the support rod 1 is connected to the first crossbeam 10 of the shelf through the first connecting member 5, and the other end is connected to the second crossbeam 20 of the shelf through the first connecting member 5. The waist-shaped hole 51 is used for fasteners to pass through.

[0028] Combine Figure 1 、 Figure 2 and Figure 4 As shown, the reversing structure of this embodiment further includes a second connecting member 6, which is used to connect the support rod 1 and the main channel track 30 of the shelf. Specifically, the second connecting member 6 includes a first plate 61 and a second plate 62 connected to each other. The first plate 61 and the second plate 62 can be integrally bent into an L-shape by plate materials. The first plate 61 and the second plate 62 are respectively provided with connecting holes, wherein the first plate 61 is used to connect to the support rod 1 of the reversing structure, and the second plate 62 is used to connect to the main channel track 30.

[0029] Further, combined with Figure 1 、 Figure 2 and Figure 5 As shown, the reversing structure of this embodiment further includes a third connecting member 7, which is used to connect the main channel rail 30 of the shelf to the second connecting member 6. In other words, the support rod 1 of the reversing structure and the main channel rail 30 of the shelf are connected via the second connecting member 6 and the third connecting member 7. The second connecting member 6 is fastened to the support member and the third connecting member 7, and the third connecting member 7 is fastened to the main channel rail 30. The above solution significantly improves the connection strength between the support rod 1 of the reversing structure and the main channel rail 30 of the shelf, thereby increasing the support strength of the support rod 1 on the reversing rail 2, and further improving the support stability of the reversing rail 2 on the shuttle 40.

[0030] Specifically, if Figure 5 As shown, the third connecting member 7 of this embodiment includes a third plate 71 and a fourth plate 72 connected to each other. The third plate 71 and the fourth plate 72 can be integrally bent into an L-shape by forming a plate. The third plate 71 is used to connect to the main channel rail 30, and the fourth plate 72 is used to connect to the second plate 62 of the second connecting member 6. Preferably, a reinforcing plate 73 is connected between the third plate 71 and the fourth plate 72 to enhance the connection strength between the two.

[0031] like Figure 3As shown, the method of using the reversing structure of this embodiment is as follows: two reversing structures are set at the intersection of the main channel and the sub-channel of the shelf, wherein the two ends of the support rod 1 of each reversing structure are respectively connected to the first beam 10 and the second beam 20 of the shelf and aligned with the track of the sub-channel, so that the reversing track 2 of each reversing structure and the track of the sub-channel are located in the same straight line, and the main channel track 30 is located in the first accommodating space 32 or the second accommodating space 42 of each reversing structure. When the four-way shuttle 40 runs on the main channel to the reversing structure, the four-way shuttle 40 lifts the main running wheels and lowers the sub-running wheels to the reversing track 2 of the reversing structure. The four-way shuttle 40 runs on the reversing track 2 and passes through the first transition track 3 or the second transition track 4 to enter the corresponding sub-channel.

[0032] To sum up, the reversing structure of the four-way shuttle 40 in this embodiment includes a support rod 1 and a reversing track 2, a first transition track 3 and a second transition track 4 respectively installed on the support rod 1. The two ends of the support rod 1 are respectively connected to the first beam 10 and the second beam 20 of the shelf. The support rod 1 is also connected to the main channel track 30 through the second connecting member 6 and the third connecting member 7, which greatly improves the connection strength between the support rod 1 and the shelf, that is, improves the supporting ability and stability of the support rod 1 on the reversing track 2, thereby improving the stability of the installation of the reversing track 2, and can avoid the problem of shaking of the four-way shuttle 40 when being transported on the reversing track 2.
