RGV cars are usually equipped with advanced navigation systems, control systems and sensors, which can accurately control the driving path and speed to ensure the accuracy and efficiency of material handling.

[0003] In the related art, a heavy-duty RGV structure includes a vehicle body. A pulley adapted to the track is fixedly connected to the bottom of the vehicle body. A carrying platform is installed on the top of the vehicle body. A conveying mechanism is installed on the carrying platform. The conveying mechanism includes a plurality of conveying rollers rotatably installed on the carrying platform. Sprockets are fixedly connected to all of the plurality of conveying rollers.

During the downward movement of the support plate 52, the support plate 52 drives the control board 64 to move. The control board 64 drives the control block 66 to move. When the control block 66 contacts the ground, the control block 66 moves relative to the control board 64, and the first switch 67 moves relative to the second switch 68. When the pulley 53 contacts the ground, the control board 64 also contacts the ground. At the same time, the first switch 67 and the second switch 68 contact each other. The storage battery energizes the electromagnet 61, and the electromagnet 61 attracts the iron block 62. The iron block 62 drives the driving motor 41 to move.

[0034] Refer to Figures 5 to 8, the control board 64 is slidably mounted on the support board 52. A moving mechanism 7 is mounted on the vehicle body 1.

When the discharging of goods is completed, the driving motor 41 is started to reverse. The driving motor 41 drives the moving plate 12 to move toward the side close to the vehicle body 1. The moving plate 12 drives the support board 52 to move. The moving rod 71 passes through the support board 52 again and pushes the control board 64 to move. At the same time, the moving rod 71 contacts the abutting rod 75 and pushes the abutting rod 75 to move. The abutting rod 75 drives the second switch 68 to move, so that the second switch 68 separates from the first switch 67. The driving motor 41 returns to the initial position, and the driving motor 41 drives the support board 52 to move upward.

[0036] Refer to Figures 6 to 9 , an installation groove is formed on the inner wall of the installation cavity. The limiting mechanism 8 includes a limiting spring 81 fixedly connected to the inner wall of the installation groove.

A limiting inclined surface capable of contacting the control block 66 is formed on the limiting block 82. An unlocking rod 83 passes through the control board 64. An unlocking groove for the unlocking rod 83 to insert is formed on the limiting block 82. An unlocking inclined surface in contact with the unlocking rod 83 is formed on the inner wall of the unlocking groove. When the control block 66 moves relative to the control board 64, the control block 66 pushes the limiting block 82 to move through the limiting inclined surface. When the limiting block 82 is opposite to the plugging groove, the limiting spring 81 pushes the limiting block 82 to insert into the plugging groove, and the limiting block 82 locks the control block 66.

During the process of the support plate 52 driving the control board 64 to move upward, the control board 64 drives the pushing rod 91 and the unlocking rod 83 to move. First, the second spherical surface contacts the second retaining rod 93, and the second retaining rod 93 pushes the unlocking rod 83 to move. The unlocking rod 83 pushes the limiting block 82 out of the insertion slot through the unlocking inclined surface, releasing the locking of the control block 66. The third spring 65 pushes the control block 66 back to the initial position. Then, the first spherical surface contacts the first retaining rod 92, and the first retaining rod 92 pushes the pushing rod 91 to move. The pushing rod 91 pushes the moving frame 73 to move. The moving frame 73 drives the abutting rod 75 to separate from the moving rod 71, facilitating continued use next time.

[0038] The implementation principle of an embodiment of a latent shuttle - type heavy - duty RGV structure for machining in the present invention is as follows: When it is necessary to unload goods, first move the vehicle body 1 to one side of the unloading station, and then start the driving motor 41. The driving motor 41 drives the support screw 51 to rotate. The support screw 51 drives the pulley 53 to move. When the pulley 53 contacts the ground, the control board 64 also contacts the ground. At the same time, the first switch 67 contacts the second switch 68, and the storage battery energizes the electromagnet 61. The electromagnet 61 attracts the iron block 62. The iron block 62 drives the driving motor 41 to move. The driving motor 41 drives the locking rod 32 to insert into the locking slot to lock the moving plate 12 and the carrying platform 11. At the same time, the driving motor 41 drives the second bevel gear 411 to move, causing the second bevel gear 411 to separate from the first bevel gear 421, and the fourth bevel gear 412 to mesh with the third bevel gear 431. The driving motor 41 drives the threaded barrel 43 to rotate. The threaded barrel 43 drives the moving plate 12 to move. The moving plate 12 drives the carrying platform 11 to move toward the side close to the unloading station. When the moving plate 12 contacts the unloading station, start the conveying mechanism 2, and the goods can be unloaded.
