DETAILED DESCRIPTION

[0021] The technical scheme of the present invention will be clearly and completely described below in conjunction with specific embodiments, but those skilled in the art should understand that the embodiments described below are only used to illustrate the present invention and should not be regarded as limiting the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 6 As shown, the AGV dual-vehicle linkage system 100 according to an embodiment of the present invention includes two vehicles 101 aligned front and back, and the two vehicles 101 can carry objects together. The vehicle 101 includes a vehicle body 10, a hollow plate 20, an inclined block 30 and a pad 40.

[0023] A plurality of first wheels 11 are disposed below the vehicle body 10 , and rectangular grooves 12 are disposed on both sides of the vehicle body 10 , and first cylinders 13 are installed inside the rectangular grooves 12 .

[0024] The hollow plate 20 is slidably disposed in the rectangular groove 12 , and the hollow plate 20 is connected to the first cylinder 13 , and a second cylinder 21 is disposed at the bottom of the hollow plate 20 along the length direction thereof.

[0025] It should be noted that wireless transmission elements are also provided on the first cylinder 13 and the second cylinder 21 for wirelessly controlling the first cylinder 13 and the second cylinder 21 .

[0026] The side surface of the inclined block 30 is triangular, and the inclined block 30 is slidably disposed in the hollow plate 20 , and a higher end of the inclined block 30 is connected to the second cylinder 21 .

[0027] The side of the pad 40 is triangular, and the pad 40 is connected to the bottom of the hollow plate 20 through a return spring 41. The pad 40 and the inclined surface of the inclined block 30 are arranged relatively parallel. The second cylinder 21 can drive the inclined block 30 to move in the hollow plate 20, and the inclined block 30 gradually lifts the pad 40.

[0028] The AGV dual-vehicle linkage system 100 proposed by the present invention has the following beneficial effects: When the width of the transported goods is greater than the width of the vehicle body 10, the first cylinder 13 extends the hollow plate 20 from the rectangular groove 12 to increase the load width of the platform, which is conducive to increasing the width of the vehicle body 10 through this operation. Then the output end of the second cylinder 21 extends to move with the inclined block 30. When the inclined block 30 moves, it will force the pad 40 to rise and the return spring 41 to be stretched, so that the pad 40 is flush with the vehicle body 10. After being flush, it is convenient to share the weight of the goods. The return spring 41 is convenient for the pad 40 to return to the bottom when the inclined block 30 is retracted. In some embodiments, the slopes of the sloped surfaces of the sloped block 30 and the backing plate 40 are consistent in inclination.

[0029] In some embodiments, there are four return springs 41 , and the four return springs 41 are disposed at four corners of the backing plate 40 .

[0030] In some embodiments, a plurality of first cylinders 13 are installed inside the rectangular groove 12 , and the plurality of first cylinders 13 are all connected to the hollow plate 20 .

[0031] In some embodiments, the AGV dual-vehicle linkage system 100 further includes a disassembly and assembly mechanism 50 and a second wheel 60 .

[0032] The disassembly and assembly mechanism 50 includes a hollow column 51, a rotating shaft 52, a disc 53, an insert block 54 and a protrusion 55. The rotating shaft 52 is arranged on the side of the vehicle body 10. The hollow column 51 is rotatably mounted on the rotating shaft 52. A through hole 551 is arranged on the hollow column 51. The through hole 551 is connected to the interior of the hollow column 51. The insert block 54 is inserted into the through hole 551. The protrusion 55 is arranged in the interior of the hollow column 51 and is connected to the insert block 54. The disc 53 is arranged on the rotating shaft 52. The disc 53 is provided with an arc groove 531. The protrusion 55 is installed in the arc groove 531.

[0033] A hollow groove 61 is provided through the second wheel 60 , and a slot 62 is provided inside the hollow groove 61 . The rotation of the disc 53 can drive the insert block 54 to extend or retract into the hollow column 51 , so that the hollow column 51 is inserted into the hollow groove 61 , and the insert block 54 is inserted into the slot 62 .

[0034] It should be noted that the second wheel 60 is a solid wheel that can improve the load-bearing capacity. By increasing the number of wheels to distribute the pressure, the purpose of large load-bearing can be achieved. In actual operation, when it is necessary to increase the load-bearing capacity of the vehicle body 10, the second wheel 60 can be installed on the vehicle body 10 through the disassembly and assembly mechanism 50.

[0035] In some embodiments, four through holes 551 are arranged on the circumference of the hollow column 51 , four arc grooves 531 are arranged on the disk 53 , there are four inserting blocks 54 and four protrusions 55 , and four slots 62 are arranged inside the hollow groove 61 along the circumference.

[0036] In some embodiments, the number of the first wheels 11 and the number of the second wheels 60 are the same, and the first wheels 11 and the second wheels 60 are arranged alternately.

[0037] In the present invention, the rotating shaft 52 drives the disc 53 to rotate counterclockwise. Since the protrusion 55 is located inside the arc groove 531, the four plug blocks 54 are retracted into the inside of the hollow column 51 when the disc 53 rotates counterclockwise. Then, the hollow groove 61 of the second wheel 60 is inserted into the outside of the hollow column 51. Then, the disc 53 is rotated clockwise through the rotating shaft 52, and then the four plug blocks 54 are extended out and inserted into the inside of the slot 62. This is conducive to fixing the second wheel 60 on the outside of the hollow column 51 to achieve the installation of the second wheel 60 and increase the load capacity. In addition, the disassembly and assembly mechanism can quickly disassemble the old second wheel 60 for replacement.
