DETAILED DESCRIPTION

[0022] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1-6 As shown, the present embodiment provides a push-pull conveying loading and unloading mechanism of an RGV trolley, which includes an RGV trolley body 1 and a track 2. A loading box 3 is installed above the RGV trolley body 1. A lifting structure 4 is arranged on the RGV trolley body 1. The lifting structure 4 includes a plurality of first electric guide rails 5 installed on the top of the RGV trolley body 1, and movable blocks 6 are installed on the first electric guide rails 5. A plurality of folding frames 7 connected with the movable blocks 6 are slidably installed at the bottom of the loading box 3; through the setting of the lifting structure 4, the height of the loading box 3 can be adjusted, and shelves of different heights can also be loaded and unloaded; when the plurality of first electric guide rails 5 are started at the same time to drive the plurality of movable blocks 6 to move closer to each other, the folding frame 7 is vertically folded to drive the loading box 3 to lift upward. This structure can accurately adjust the height of the loading box 3 to adapt to the loading and unloading of shelves of different heights.

[0024] A first motor 8 is fixedly installed on one side of the loading box 3, and a conveyor belt 9 connected to the first motor 8 is arranged inside the loading box 3. When in use, the first motor 8 is started to drive the conveyor belt 9 to run. During the operation of the conveyor belt 9, the goods on the shelf can be loaded and unloaded, thereby improving the loading and unloading efficiency.

[0025] A motor protection shell 10 connected to the loading box 3 is installed on the outer side of the first motor 8, and a heat dissipation port 26 is arranged on the motor protection shell 10. The arrangement of the motor protection shell 10 and the heat dissipation port 26 can protect the first motor 8 and prevent the first motor 8 from being accidentally damaged by collision. The heat dissipation port 26 arranged on the motor protection shell 10 is used to dissipate the heat generated by the operation of the first motor 8.

[0026] A plurality of sliding frames 11 are symmetrically installed at one end of the loading box 3, and a closed door 12 is slidably installed between the plurality of sliding frames 11. A plurality of racks 13 are arranged on the back of the closed door 12. A plurality of second motors 14 are fixedly installed on the top of the loading box 3, and a gear 15 meshing with the rack 13 is fixedly installed on the output end of the second motor 14; through the arrangement of the sliding frame 11, the closed door 12, the rack 13, the second motor 14 and the gear 15, after the material is loaded into the loading box 3, the plurality of second motors 14 are started to drive the plurality of gears 15 to rotate. Since the rack 13 and the gear 15 are meshingly connected, the rack 13 moves downward under the drive of the gear 15, so that one side of the loading box 3 forms a closed state, and the gear 15 reverses to lift the closed door 12 upward to unload the goods; by opening and closing the closed door 12, the material can be prevented from falling during the transfer process and the loading and unloading of the material can be facilitated, which is helpful to realize the accurate delivery and reception of the material and ensure the smooth progress of the production process.

[0027] A plurality of support plates 16 are fixedly installed below the RGV trolley body 1, a plurality of mounting plates 17 are installed on one side of the support plate 16, a bearing 18 is fixedly installed on the top of the mounting plate 17, and a limiting wheel 19 is movably installed on the bearing 18; through the arrangement of the support plate 16, the mounting plate 17, the bearing 18 and the limiting wheel 19, while the RGV trolley body 1 moves, the plurality of limiting wheels 19 can rotate on the track 2 through the bearing 18 to ensure that the trolley always remains on the correct running route and prevent the RGV trolley body 1 from detaching from the track 2.

[0028] The support plate 16 is provided with a groove 20, inside of which a second electric guide rail 21 is fixedly installed, and a transmission block 22 connected to the mounting plate 17 is installed on the second electric guide rail 21. Starting the second electric guide rail 21 drives the mounting plates 17 on the transmission block 22 to move away from each other, which can increase the spacing of the limiting wheels 19, so that the limiting wheels 19 can still limit the RGV trolley body 1 when the RGV trolley body 1 travels on tracks 2 of different widths.

[0029] A plurality of recessed holes 23 are provided on the inner wall of the loading box 3, and an electric telescopic rod 24 is provided inside the recessed holes 23, and a clamping plate 25 is fixedly installed at the output end of the electric telescopic rod 24; through the arrangement of the recessed holes 23, the electric telescopic rod 24 and the clamping plate 25, after the goods are put into the loading box 3, the plurality of electric telescopic rods 24 are started at the same time to drive the clamping plate 25 to clamp the goods, and further clamp and fix the objects to prevent the materials from shaking during the transfer process.

[0030] like Figure 1-Figure 6 As shown, the working process of the push-pull conveying loading and unloading mechanism of the RGV trolley provided in this embodiment is as follows:

[0031] When multiple first electric guide rails 5 are started at the same time to drive multiple movable blocks 6 to move closer to each other, the folding frame 7 is vertically folded to drive the loading box 3 to lift upward. This structure can accurately adjust the height of the loading box 3 to adapt to the loading and unloading of shelves of different heights. Start the first motor 8 to drive the conveyor belt 9 to run. During the operation of the conveyor belt 9, the goods on the shelf can be loaded and unloaded, which can improve the loading and unloading efficiency. The motor protection shell 10 and the heat dissipation port 26 can protect the first motor 8 to prevent the first motor 8 from being accidentally damaged; the heat dissipation port 26 arranged on the motor protection shell 10 can dissipate the heat generated by the operation of the first motor 8; after the material is loaded into the loading box 3, start multiple second motors 14 to drive multiple gears 15 to rotate. Since the rack 13 and the gear 15 are meshingly connected, the rack 13 moves downward under the drive of the gear 15, so that one side of the loading box 3 forms a closed state, and the gear 15 reverses to lift the closed door 12 upward to unload the goods. By opening and closing the closed door 12, the material can be prevented from falling during the transfer process and the loading and unloading of the material can be facilitated, which helps to achieve accurate delivery and reception of materials and ensure the smooth progress of the production process. While the RGV trolley body 1 is moving, multiple limiting wheels 19 can rotate on the track 2 through bearings 18, which can ensure that the trolley always remains on the correct running route and prevent the RGV trolley body 1 from detaching from the track 2; starting the second electric guide rail 21 drives the mounting plates 17 on the transmission block 22 to move away from each other, which can increase the spacing between the limiting wheels 19, so that the limiting wheels 19 can still limit the RGV trolley body 1 when the RGV trolley body 1 travels on tracks 2 of different widths; after the goods are placed in the loading box 3, multiple electric telescopic rods 24 are started at the same time to drive the clamping plates 25 to clamp the goods, further clamping and fixing the objects to prevent the materials from shaking during the transfer process.

[0032] The above description shows and describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and modifications and changes made by those skilled in the art without departing from the spirit and scope of the utility model should be within the scope of protection of the claims attached to the utility model.
