Description

Technical Field

[0001] This invention relates to the field of RGVs, and more particularly to a stealthy shuttle heavy-duty RGV structure for machining. Background Technology

[0002] RGV, short for Rail Guided Vehicle, is an automated material handling device that runs on a specific track. RGVs are typically equipped with advanced navigation, control, and sensor systems that can precisely control the travel path and speed to ensure the accuracy and efficiency of material handling.

[0003] In related technologies, the heavy-duty RGV structure includes a vehicle body, with pulleys adapted to the track fixedly connected to the bottom of the vehicle body, a support platform mounted on the top of the vehicle body, and a conveying mechanism mounted on the support platform. The conveying mechanism includes multiple conveying rollers rotatably mounted on the support platform, each of which is fixedly connected to a sprocket. The multiple sprockets are driven by chains. A conveyor motor is fixedly connected to the support platform, and the output shaft of the conveyor motor is fixedly connected to one of the conveying rollers. An overlapping platform is rotatably mounted on the support platform, and a conveying mechanism is also mounted on the overlapping platform. A drive mechanism for driving the overlapping platform to rotate is mounted on the support platform. When the vehicle body moves to the unloading station, the drive mechanism is first started, which drives the overlapping platform to rotate, so that the overlapping platform overlaps on the unloading station. Then, the conveyor motor is started, which drives the conveying rollers to rotate, thereby unloading the goods.

[0004] Regarding the aforementioned technologies, during the unloading process, due to the varying distances between the vehicle body and different unloading stations, the overlapping platform may not be able to contact the unloading station after it has been flipped, resulting in a gap between the overlapping platform and the unloading station. As the goods pass through the gap, they will sway and shift, affecting the conveying accuracy of the goods. Summary of the Invention

As the support plate 52 moves downward, the support plate 52 drives the control plate 64 to move, and the control plate 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 plate 64, and the first switch 67 moves relative to the second switch 68. When the pulley 53 contacts the ground, the control plate 64 also contacts the ground, and at the same time, the first switch 67 and the second switch 68 are in contact. The battery energizes the electromagnet 61, and the electromagnet 61 attracts the iron block 62. The iron block 62 drives the drive motor 41 to move.

A push mechanism 9 for driving the movable frame 73 to move is installed on the vehicle body 1. After the goods are unloaded, the drive motor 41 is started to reverse. The drive motor 41 drives the movable plate 12 to move towards the side closer to the vehicle body 1. The movable plate 12 drives the support plate 52 to move. The movable rod 71 passes through the support plate 52 again and pushes the control plate 64 to move. At the same time, the movable rod 71 contacts the abutment rod 75 and pushes the abutment rod 75 to move. The abutment rod 75 drives the second switch 68 to move, so that the second switch 68 is separated from the first switch 67. The drive motor 41 returns to the initial position and drives the support plate 52 to move upward.

A limiting inclined surface that can contact the control block 66 is formed on the limiting block 82. An unlocking rod 83 is provided on the control plate 64. An unlocking groove for the unlocking rod 83 to be inserted is provided on the limiting block 82. An unlocking inclined surface that contacts the unlocking rod 83 is formed on the inner wall of the unlocking groove. When the control block 66 moves relative to the control plate 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 plug-in groove, the limiting spring 81 pushes the limiting block 82 to be inserted into the plug-in groove, and the limiting block 82 locks the control block 66.

First, the second spherical surface contacts the second stop lever 93, which pushes the unlocking lever 83 to move. The unlocking lever 83 pushes the limiting block 82 out of the insertion slot through the unlocking ramp, releasing the lock on 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 stop lever 92, which pushes the push rod 91 to move. The push rod 91 pushes the moving frame 73 to move, and the moving frame 73 causes the abutment rod 75 to separate from the moving rod 71, making it easy to continue using next time.

The drive motor 41 drives the support screw 51 to rotate, and 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 and the second switch 68 are in contact, the battery powers the electromagnet 61, the electromagnet 61 attracts the iron block 62, and the iron block 62 drives the drive motor 41 to move. The drive motor 41 drives the locking rod 32 to insert into the locking groove, locking the moving plate 12 and the support platform 11. At the same time, the drive 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 drive motor 41 drives the threaded cylinder 43 to rotate, and the threaded cylinder 43 drives the moving plate 12 to move. The moving plate 12 drives the support platform 11 to move towards the side closer to the unloading station. When the moving plate 12 contacts the unloading station, the conveying mechanism 2 is activated, and the goods can be unloaded.
