Description

Technical Field

[0001] The utility model relates to the technical field of AGV transport vehicles, in particular to a linkage loading and unloading protection mechanism for an AGV transport vehicle. Background Art

[0002] AGV transporter is also commonly called AGV cart. Patent publication number CN218519572U discloses an AGV transporter that is easy to load and unload. The first driving mechanism can make the placement table tilt on the body, and the connecting block slides on the slide bar, so that the goods on the placement table can slide, which is convenient for unloading the goods, thereby improving the handling efficiency of the goods. The second driving mechanism is arranged on both sides of the body, and the first baffle and the second baffle can slide on the support rod. The second baffle and the support rod can be used to block the goods on the placement table to prevent the goods from falling from the placement table, thereby improving the handling quality of the goods.

[0003] However, when the transport vehicle is using the driving mechanism to unload, the staff needs to manually operate the lowering of the protective mechanism, which results in no faster linkage between the inclination of the placement table and the lifting and lowering of the baffle support rod, thereby further increasing the time consumed in the process, thereby reducing the unloading efficiency of the device and also subjecting the degree of automation of the device to certain limitations.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figures 1 to 4As shown, in the embodiment of the first aspect of the utility model, a linkage loading and unloading protection mechanism for an AGV transport vehicle comprises a vehicle plate 1, a servo motor 2 is fixedly installed in the middle of the side of the vehicle plate 1, a threaded rod 3 is fixedly sleeved on the output shaft of the servo motor 2, a transmission plate 4 is threadedly installed on the surface of the threaded rod 3, a vertical rod 5 is fixedly installed on the top of the transmission plate 4, a cross bar 6 is fixedly installed on the top of the vertical rod 5, a tail baffle 7 is fixedly installed on one end of the transmission plate 4, a cross column 8 is fixedly installed on the inner wall of the tail baffle 7, a roller 9 is rotatably installed on the top surface of the tail baffle 7, a card slot 10 is provided on the outside of the vehicle plate 1, a telescopic slot 101 is provided on the inside of the telescopic slot 101, an electric hydraulic rod 102 is fixedly installed on the inside of the telescopic slot 101, a rotating shaft 12 is rotatably installed on the top surface of the vehicle plate 1, a support plate 11 is fixedly installed on the surface of the rotating shaft 12, and a signal The linkage device 13 comprises a pressure sensor 1 1301 and a pressure sensor 2 1302. The bottom ends of the pressure sensor 1 1301 and the pressure sensor 2 1302 are electrically connected to a wire 1303. One end of the wire 1303 is electrically connected to a controller 1304. The left and right ends of the controller 1304 are electrically connected to a wire 2 1305. The outer end of the wire 2 1305 is electrically connected to the servo motor 2. A protrusion is integrally formed on the inner wall of the transmission plate 4. The shape of the protrusion matches the shape of the card slot 10. A gravity card plate 14 is fixedly installed on the bottom end of the support plate 11. The shape of the gravity card plate 14 is set to an arc structure, and a soft cushion is integrally formed on the outside. The top end of the pressure sensor 1301 and the bottom end of the gravity card plate 14 fit together, and the outer end of the pressure sensor 2 1302 and the outer side of the gravity card plate 14 fit together.

[0023] In the above embodiment, it should be noted that the inclination angle of the top surface of the tail baffle 7 is the same as the flip inclination angle of the support plate 11, and the controller 1304 will send a control signal to the servo motor 2 only when the pressure sensor 1 1301 and the pressure sensor 2 1302 receive signals at the same time.

[0024] The technical effect achieved by the above embodiment is: by using the mutual adaptation of the protrusion and the groove 10, the fence formed by the transmission plate 4, the vertical rod 5 and the horizontal rod 6 can only move up and down, and no deviation to other positions will occur, thereby achieving the purpose of limiting. The soft pad on the outside of the gravity clamping plate 14 can effectively apply lateral pressure to the pressure sensor 1302, making its signal reception more accurate.

[0025] Example 2

[0026] like Figure 1 and Figure 4As shown, a linkage loading and unloading protection mechanism for an AGV transport vehicle includes all the contents of Example 1. In addition, a sliding rod 15 is fixedly installed on the bottom end of the pallet 11, and a sleeve shaft 16 is slidably installed on the surface of the sliding rod 15. A support frame 17 is fixedly installed on the bottom end of the sleeve shaft 16, and a connecting ring 18 is fixedly installed on the bottom end of the support frame 17. A connecting shaft is arranged inside the connecting ring 18, and the surface of the connecting shaft and the top end of the electric hydraulic rod 102 are rotatably connected to each other.

[0027] The technical effect achieved by the above embodiment is: the several triangular structures formed by the support frame 17 can effectively improve the stability of the connection between the two, and the rotational connection between the electric hydraulic rod 102 and the connecting ring 18 is realized through the connecting shaft, and there will be no mutual repulsion of movement due to the movement of the positions of the two, thereby ensuring the normal lifting function of the support plate 11.

[0028] Working principle: When the support plate 11 is lifted, the gravity card plate 14 leaves the corresponding slot on the top surface of the vehicle plate 1, causing the pressure sensor 1 1301 and the pressure sensor 2 1302 to lose their signals. The wire 1303 transmits this information to the inside of the controller 1304. The controller 1304 controls the servo motor 2 through the wire 2 1305 to drive the threaded rod 3 to rotate, so that the transmission plate 4 moves downward as a whole. Therefore, the cross bar 6 leaves its original position and descends to the outer edge of the top of the vehicle plate 1. When the gravity card plate 14 is reset, the pressure sensor 1 1301 and the pressure sensor 2 1302 will transmit the signal to the inside of the controller 1304, so that the cross bar 6 is reset as a whole.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
