Those skilled in the art can appreciate that the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems in different implementation environments.

[0046] The following first introduces the pallet three-dimensional warehouse system of this application. Figures 1 to 16 The schematic diagram shown in FIG. 1 shows a track system for an RGV trolley according to an embodiment of the present application. The track system includes a track portion 1, a cargo support portion 2, and a rear beam portion 3. The specific configuration is as follows: Figure 1 and Figure 2 As shown, unless otherwise specified in this application, the directions of this application, such as up, down, left, right, front, and back, shall be in accordance with Figure 1 The direction shown is used for explanation, wherein the track portion 1 includes two parallel tracks (1a, 1b) on the left and right, the cargo support portion 2 includes a plurality of cargo supports (2a, 2b) on the left and right, and the rear beam portion 3 includes two rear beams (3a, 3b) arranged in parallel on the left and right. The cargo support (2a) on the left is used to be clamped between the left track (1a) and the left rear beam (3a). The schematic diagram of the structure after clamping is shown in FIG. Figure 3 As shown in the schematic diagram, the cargo support (2b) on the right side is used to clamp between the right side track (1b) and the right side rear beam (3b). The above scheme is introduced in detail as follows:

[0047] The structure of the track portion 1 can be found in Figure 4 and Figure 5The schematic diagram shown in the figure has a structure including a first cargo support connection panel 11, the upper part of which is connected to a second cargo support connection panel 12 inclined outward, and the upper side of the second cargo support connection panel 12 is connected to a track panel 13. Specifically, the first cargo support connection panel 11 is "L"-shaped, and after being installed in place, its side wall is in a vertical direction. There is a certain angle between the second cargo support connection panel 12 and the first cargo support connection panel 11, that is, the angle at which the second cargo support connection panel 12 is inclined toward the track panel 13 is an obtuse angle (this angle may be based on actual conditions, such as the size, aesthetic requirements, use effect, and processing convenience of the track portion 1, the cargo support portion 2, and the rear beam portion 3, etc.) Figure 5 As an example, the angle between the second cargo support connection panel 12 and the first cargo support connection panel 11 is generally 120-150 degrees, preferably 135 degrees), so that the cargo support part 2 is conveniently inserted into the first cargo support installation through hole 14 opened on the second cargo support connection panel 12 along the upper part of the first cargo support installation through hole 14 opened on the first cargo support connection panel 11. The track panel 13 is in an inverted L shape, and the first cargo support connection panel 11, the second cargo support connection panel 12 and the track panel 13 can be formed in an integrated manner, for example, by a bending machine. Figure 3-Figure 7 can also be in the form of splicing, for example, by welding the first cargo support connecting panel 11, the second cargo support connecting panel 12 and the track panel 13 are spliced ​​as shown Figure 3-Figure 7 In addition, the side panels of the track panel 13 are provided with positioning holes 131 arranged at equal intervals, such as Figure 7 As shown, the positioning hole 131 is in a circular, square, oval or other shape, so as to be used for calculating the travel distance and positioning when the RGV vehicle is traveling.

[0048] The first cargo support mounting through holes 14 of the present application are provided with a plurality of holes, which are arranged transversely on the track portion 1, and are specifically provided on the first cargo support connecting panel 11 and the second cargo support connecting panel 12, such as Figure 4 and Figure 5 As shown in the schematic diagram, the first cargo support mounting through holes 14 of the present application can be arranged in an equidistant arrangement, or the spacing between the first cargo support mounting through holes 14 can be set according to the designed distance according to the use environment and / or mechanical characteristics. Each of the first cargo support mounting through holes 14 is composed of two through holes that are mirror images of each other. The structure of the first cargo support mounting through holes 14 can be referred to Figure 8As shown in the schematic diagram, each through hole includes a first entrance section through hole 141 and a first clamping section through hole 142 from top to bottom. The first clamping section through hole 142 is bent toward the side of the through hole mirrored therewith, and a first clamping protrusion 143 is formed at the bend. The first entrance section through hole 141 is a through hole of equal width at the top and bottom, starting from the first cargo support connection panel 11 and extending to the second cargo support connection panel 12. In addition, Figure 8 In the schematic diagram shown, the first clamping section through hole 142 is bent toward the side of the through hole that is mirrored therewith, that is, the first clamping section through hole 142 of the through hole on the left is bent toward the right through hole, and the first clamping section through hole 142 of the through hole on the right is bent toward the left through hole. And the curvature of the first clamping section through hole 142 is set to the first curvature from the end of the first entrance section through hole 141 to the top of the first clamping protrusion 143, the curvature of the first clamping section through hole 142 is set to the second curvature at the first clamping protrusion 143, and the curvature of the first clamping section through hole 142 is set to the third curvature below the first clamping protrusion 143, and the third curvature>=the first curvature>the second curvature, so that the left through hole has a rightward force on the cargo support part 2, and the right through hole has a leftward force on the cargo support part 2. The first clamping protrusion 143 is in a nose-shaped structure, so that the end through hole of the cargo support part 2 can slide down along the oblique side of the first clamping protrusion 143 to the bottom of the first clamping section through hole 142, so that the bottom of the first clamping protrusion 143 clamps the end through hole of the cargo support part 2, so that the end through hole of the cargo support part 2 is subjected to a downward force, and at the same time, the bottom of the first clamping section through hole 142 causes the end through hole of the cargo support part 2 to be subjected to an upward force, so that the cargo support part 2 is reliably and firmly clamped in the first clamping section through hole 142.

[0049] The rear beam portion 3 includes a rear beam body 31, and a plurality of transversely arranged second cargo support mounting through holes 32 are provided on the rear beam body 31. The second cargo support mounting through holes 32 are arranged opposite to the first cargo support mounting through holes 14. The second cargo support mounting through holes 32 are composed of two through holes that are mirror images of each other. Each through hole includes a second entrance section through hole 321 and a second clamping section through hole 322 in sequence from top to bottom. The second clamping section through hole 322 is bent toward the side of the through hole that is mirror image thereof, and a second clamping protrusion 323 is formed at the bending portion. The curvature of the second clamping section through hole 322 is set to a first curvature from the end of the second entrance section through hole 321 to the upper part of the second clamping protrusion 323, the curvature of the second clamping section through hole 322 is set to a second curvature at the second clamping protrusion 323, and the curvature of the second clamping section through hole 322 is set to a third curvature below the second clamping protrusion 323. The structure and working principle of the second cargo support mounting through hole 32 are consistent with the structure and working principle of the first cargo support mounting through hole 14, and will not be described in detail in this application.

[0050] The structure of the cargo support portion 2 can be found in Figures 9 to 14 As shown in the schematic diagram, its specific structure includes a cargo support body 21, one end of the cargo support body 21 is provided with a track snap hole 22, and the other end of the cargo support body 21 is provided with a rear beam snap hole 23; the track snap hole 22 is snapped into the first clamping section through hole 142 along the first entrance section through hole 141, so that the first clamping protrusion 143 is snapped into the track snap hole 22, and the rear beam snap hole 23 is snapped into the second clamping section through hole 322 along the second entrance section through hole 321, so that the second clamping protrusion 323 is snapped into the rear beam snap hole 23. Since the first clamping protrusion 143 and the second clamping protrusion 323 are both nose-shaped structures, and in addition, the first cargo support mounting through hole 14 and the second cargo support mounting through hole 32 have a bending curvature and a bending direction, the first cargo support mounting through hole 14 cooperates with the first clamping protrusion 143, so that the first clamping protrusion 143 clamps the rail clamping hole 22, and the second clamping protrusion 323 clamps the rear beam clamping hole 23.

[0051] The specific structure of the track buckle hole 22 can be found in Fig.11 and Fig.12As shown in the schematic diagram, the track buckle hole 22 includes a first buckle hole 221 and a second buckle hole 222, the first clamping protrusion clamping hole 2211 and the second clamping protrusion clamping hole 2212 are integrally formed, and the first buckle hole 221 is located above the second buckle hole 222; the first buckle hole 221 includes a first clamping protrusion clamping hole 2211, and the lower part of the first clamping protrusion clamping hole 2211 is connected to the second clamping protrusion clamping hole 2212, and the second clamping protrusion clamping hole 2212 is set as a through hole with a lower width and a upper narrowness (such as Fig.11 The triangle shown). The second snap hole 222 includes a first snap-in end 2221, and the bottom sides of the first snap-in end 2221 are provided with rounded corners to facilitate guiding the first snap-in end 2221 into the first cargo support mounting through hole 14. In addition, the first snap-in end 2221 is at a certain distance from the extension line of the bottom side of the cargo support body 21, so that the bottom side of the cargo support body 21 forms a block on the side of the first snap-in end 2221. A second snap-in guide hole 2222 is provided on the first snap-in end 2221, and the first snap-in end 2221 and the second snap-in guide hole 2222 are integrally formed, and the second snap-in guide hole 2222 is set as a through hole that is wide at the top and narrow at the bottom. Specifically, the distance between the top of the second snap-in guide hole 2222 and the second clamping protrusion snap-in hole 2212 is equal to or less than the distance from the first clamping protrusion 143 to the bottom side of the first clamping section through hole 142. Therefore, after the cargo support part 2 is installed with the track part 1, the first clamping protrusion 143 on the track part 1 is clamped into the second clamping protrusion clamping hole 2212 on the cargo support part 2. In addition, since the first clamping protrusion 143 is nose-shaped as a whole, Figure 8 As shown in the schematic diagram, the left side of the bottom edge of the first clamping protrusion 143 on the left side is slightly lower than the right side, and the right side of the bottom edge of the first clamping protrusion 143 on the right side is slightly lower than the left side. When the distance between the top of the second clamping guide hole 2222 and the second clamping protrusion clamping hole 2212 is smaller than the distance from the first clamping protrusion 143 to the bottom edge of the first clamping section through hole 142, the first clamping protrusion 143 can also be clamped into the second clamping protrusion clamping hole 2212, and the clamping force is better.

[0052] Furthermore, the side of the rear beam buckle hole 23 is inclined outward. The general installation sequence is to install the rear beam part 3 of the vertical warehouse first, build the shape of the vertical warehouse, and then install the cargo support part 2 and the track part 1. Figure 1 and Figure 2 As shown in the schematic diagram, the cargo support body 21 and the track need to be installed between the two rear beam bodies 31. The installer can easily snap the rear beam body 31 into the second snap hole 222, and also snap the rear beam snap hole 23 into the second snap guide hole 2222. The rear beam snap hole 23 is provided with a third snap hole 231 and a fourth snap hole 232. The structure of the rear beam snap hole 23 can be found in Fig.10 and Fig.14 As shown in the schematic diagram, the third snap hole 231 is located above the fourth snap hole 232; the third snap hole 231 is set as a square, and the fourth snap hole 232 is set as an open through hole. The distance between the top of the fourth snap hole 232 and the third snap hole 231 is equal to or less than the distance between the second clamping protrusion 323 and the bottom edge of the second clamping section through hole 322. The structure of the rear beam snap hole 23 is similar to that of the track snap hole 22, and will not be repeated in this article.

[0053] The two ends of the upper panel of the track panel 13 are parallel beveled edges. The two ends of the upper panel of the track panel 13 of the present application are parallel beveled edges. After the track system is installed, the two adjacent panels are spliced ​​into an oblique gap, so that when the wheels of the RGV trolley pass through the gap, the wheels of the RGV trolley are always in contact with the track panel, thereby reducing the vibration and noise of the trolley passing through the splicing of the track panels, making the RGV trolley run more smoothly.

[0054] The side of the upper panel of the track panel 13 close to the cargo support body 21 is lower than the side away from the cargo support body 21. When the wheels of the RGV trolley are running on the track, the left wheel of the RGV trolley is acted on by the left track panel 13 to the left, and the right wheel of the RGV trolley is acted on by the right track panel 13 to the right, so that the RGV trolley runs smoothly on the track with less shaking.

[0055] Furthermore, the upper panel end of the cargo support body 21 that is close to the track portion 1 is connected to a cover plate 24, which can be seen in Fig.10 and Fig.13 As shown in the schematic diagram, the cover plate 24 is tilted downward toward the track portion 1, and the end of the cover plate 24 does not exceed the length of the side panel of the cargo support body 21. The cover plate 24 is integrally formed with the upper panel of the cargo support body 21. The cover plate 24 is for aesthetics and for exerting downward force on the second cargo support connecting panel 12, so that the cargo support body 21 and the track portion 1 are firmly buckled, improving the running stability of the RGV trolley.

[0056] In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more than two. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with substantially the same functions and effects. Those skilled in the art will understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily limit them to be different. The above-described embodiments of the present application do not constitute a limitation on the scope of protection of the present application.
