Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific examples, which should not be construed as limiting the invention.

In order to facilitate the illustration of the specific structure of the present invention, in some drawings, some of the baffle/housing etc. are hidden, but will not substantially affect the improvement point of the present invention.

Referring to fig. 1 and 2, the automatic guided vehicle with lifting positioning of the present invention includes a vehicle body 2, a traveling device 4, a lifting device 3, a top plate 15 and a shelf 1, wherein the traveling device 4 is used for moving the vehicle body 2, and the lifting device 3 is used for lifting the shelf 1. The lifting device 3 and other components requiring electrification control are connected to the control unit 6 so as to be controlled by the control unit 6.

As shown in fig. 3 to 5, the traveling device 4 is located at the bottom of the vehicle body 2, and the traveling device 4 includes rollers, a driving mechanism, and the like. The lifting device 3 is located in the vehicle body 2, the lifting device 3 includes a driving motor 11 and a plurality of rotating shafts (not labeled in the figure), the driving motor 11 may be a servo motor; the belt wheel 13 is fixed on the rotating shaft, the jacking screw rod 14 is connected with the inner thread of the rotating shaft, the top plate 15 is fixed on the jacking screw rod 14, when the driving motor 11 drives the belt wheel 13 and the rotating shaft to rotate through the transmission belt 12, the top plate 15 vertically ascends and descends, namely, the driving motor 11 drives the belt wheel 13 to rotate through the transmission belt 12, the belt wheel 13 drives the rotating shaft to rotate together, and when the rotating shaft rotates, the jacking screw rod 14 connected with the rotating shaft through the thread can realize ascending and descending motion.

As shown in the figure, for the convenience of positioning, a positioning pin 5 is arranged on the top plate 15, and a through hole 10 matched with the positioning pin 5 is arranged on the goods shelf 1. For example, in fig. 3, the shelf 1 includes a rectangular frame 7, a support plate 9 is provided on the rectangular frame 7, and a through hole 10 is opened in the support plate 9.

The utility model discloses in, the quantity of axis of rotation is four, is the rectangle and distributes, and the axis of rotation can drive roof 15 and go up and down steadily when the initiative under driving motor 11 drives.

In addition, in order to know the position of the goods shelf 1 on the vehicle body 2, the vehicle body 2 is provided with a sensor (not shown) for detecting the position of the goods shelf 1.

In order to facilitate the accurate positioning of the goods shelf 1 on the ground, the bottom of the goods shelf 1 is provided with four supporting legs 8. Preferably, the ends of the support legs 8 are tapered. Correspondingly, corresponding containing holes can be formed in the opposite surfaces, and the supporting legs 8 are embedded into the containing holes to realize the positioning of the goods shelf 1.
