Description

Technical Field

[0001] The utility model relates to the technical field of latent AGV cars, in particular to a latent AGV car with a platform expansion function. Background Technique

[0002] AGV car is short for automatic guided transportation, that is, a handling robot equipped with automatic guiding devices such as electromagnetic or photoelectric, capable of automatically driving along a specified guiding path, having programming and mode selection devices, safety protection and various loading and unloading functions. The characteristics of AGV cars are driverless, which can ensure that the system automatically drives without manual navigation, with good flexibility, high automation and intelligence levels. Moreover, AGV cars can be flexibly configured according to requirements of storage positions, production process flows, etc., and the cost of changing the running path is very low compared with traditional conveyor belts or rigid conveyor lines;

[0003] At present, most of the existing latent AGV cars drive the whole platform to rise through the hydraulic cylinder inside the car body, and then the platform lifts the materials through the base for handling. However, since the size of the platform is fixed, the latent AGV car can only lift a group of materials for handling each time. Although it can carry multiple layers of goods through brackets, the number of goods carried by the latent AGV car in the horizontal direction will not increase, and the method of increasing the handling quantity longitudinally will also increase the height of the top of the latent AGV car, resulting in a continuous increase in the overall center of gravity and thus a decrease in stability.

First connecting rods 10 and second connecting rods 11 are rotatably arranged on the surface of the second groove 4. Third chutes 12 and fourth chutes 13 are arranged on the side walls of the first connecting rods 10 and the second connecting rods 11. The third chutes 12 and the fourth chutes 13 are parallel to each other. Two support parts are detachably installed on both sides of the vehicle body 1 respectively. The tops of the two support parts are respectively connected to the bottoms of the first connecting rods 10 and the second connecting rods 11. Sinking grooves 24 for facilitating movement are arranged on the surfaces of the first expansion platform 5 and the second expansion platform 6.

[0026] Please refer to Figure 1 , 2 , 3 and 4. Under normal circumstances, the hydraulic cylinder can drive the entire loading platform 2 to move upward. At this time, the loading platform 2 can lift the goods from the bottom, and then convey the goods under the movement of the vehicle body 1. When the number of goods to be transported is large, first rotate the first connecting rod 10 and the second connecting rod 11 to make the first connecting rod 10 and the second connecting rod 11 parallel to each other, and then push the first expansion platform 5 and the second expansion platform 6 through the sinking groove 24. At this time, the first expansion platform 5 can drive the limiting part 7 to move inside the first chute 8. With the push of the first expansion platform 5, the limiting part 7 can gradually enter the third chute 12. With the push of the second expansion platform 6, the second expansion platform 6 can drive the limiting part 7 to move from the second chute 9 to the fourth chute 13. At this time, the total top area of the first expansion platform 5, the second expansion platform 6 and the loading platform 2 will increase, and more goods can be supported by the first expansion platform 5 and the second expansion platform 6 at this time.

[0027] The support member includes a base 14, a metal support seat 15 and a supporting seat 16. The base 14 is detachably mounted on the side wall of the vehicle body 1. The metal support seat 15 is rotatably arranged on the surface of the base 14. The supporting seat 16 is fixedly arranged on the top of the metal support seat 15. The top of the supporting seat 16 is connected to the first connecting rod 10 and the second connecting rod 11 through a connecting structure.

The first protrusion 17 is vertically movably arranged on the top of the supporting seat 16. The second protrusion 18 is arranged on the top of the first protrusion 17. The first card slot 19 and the second card slot 20 are both arc-shaped structures as a whole. The center of the circle corresponding to the first card slot 19 and the second card slot 20 is on the same straight line as the center of the circle when the metal support seat 15 rotates.

[0028] See also Figure 1 , 2 , 5 and 6, when the first expansion platform 5 and the second expansion platform 6 support the goods, they need to be stabilized from the bottom through the support members to ensure that the first connecting rod 10 and the second connecting rod 11 can stably support the goods. Before rotating the first connecting rod 10 and the second connecting rod 11, the metal support seat 15 needs to be separated from the vehicle body 1, and then the metal support seat 15 is rotated to make it rotate more than 90°, and then the first connecting rod 10 and the second connecting rod 11 are set parallel to each other. At this time, the metal support seat 15 is rotated in the opposite direction so that the first protrusion 17 and the second protrusion 18 are respectively engaged into the first groove 19 and the second groove 20. At this time, when the hydraulic cylinder drives the cargo platform 2 to move upward, it can drive the first protrusion 17 to rise on the top of the supporting seat 16 through the first connecting rod 10 and the second connecting rod 11.

[0029] It should be noted that if the cargo is placed directly on the cargo platform 2, the first expansion platform 5 and the second expansion platform 6, the hydraulic cylinder may not be started. At this time, the first connecting rod 10 and the second connecting rod 11 can bear part of the pressure of the cargo through the support member.

[0030] A through hole 21 is provided on the surface of the base 14 . A bolt 22 passes through the through hole 21 . One end of the bolt 22 is threadedly connected to the side surface of the vehicle body 1 .
