Abstract
Description
Technical Field
[0001] This utility model relates to a track reversing mechanism, and more particularly to a track reversing mechanism for an RGV trolley. Background Technology
[0002] RGV, or Rail Guided Vehicle, is an automated material transport device that runs along a fixed track. It is widely used in automated warehouses, smart manufacturing production lines, port logistics, and other scenarios. In the fields of automated logistics and smart manufacturing, RGV is widely used due to its efficient material transfer capabilities. Its track reversing mechanism is the core component for realizing multi-path scheduling.
[0003] In existing technologies, track reversing mechanisms mostly rely on the mechanical cooperation between the turntable and the track to complete the steering. However, in actual operation, due to factors such as the inertia of the trolley, the gap between the track and the track, and the rotation error of the turntable, the positioning accuracy of the trolley is often insufficient.
[0004] After the trolley enters the turntable, the lack of an effective positioning device makes it difficult to ensure that the angle between the trolley body and the connecting track is completely consistent. During the rotation of the turntable and the turning of the trolley, lateral deviation is prone to occur, which can lead to collisions and jamming between the wheels and the track flanges, or even derailment accidents, seriously affecting the transfer efficiency and equipment safety. To address this issue, a track reversing mechanism for RGV trolleys is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a track reversing mechanism for RGV trolleys, aiming to improve the problem of easy derailment during docking of some devices in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The outer right side of each of the two rotating rods is rotatably connected to a long connecting rod. The far side of the two long connecting rods is fixedly connected to the near side of the two rotating L-shaped rods.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a track reversing mechanism for an RGV trolley, comprising multiple support columns 1, each of which is externally fixedly connected to a support rod 2, providing stable support for the entire device. Two rotating L-shaped rods 3 are rotatably connected internally to the support rods 2. A drive assembly is rotatably connected to the left side of the right rotating L-shaped rod 3. Two fixed rods 6 are fixedly connected to the far sides of the support rods 2, and a fixed groove plate 7 is fixedly connected to the near sides of the two fixed rods 6. The fixed rods 6 connect the fixed groove plate 7 to the support rods 2, providing support for the fixed groove plate 7. A positioning assembly is slidably connected to the left side of the fixed groove plate 7. A fixed column 8 is fixedly connected to the right side of the fixed groove plate 7, providing a rotation fulcrum for its external structure. A connecting rod assembly is rotatably connected to the outside of the fixed column 8. The drive assembly includes a cylinder 4, the right side of which is rotatably connected to the outside of the right rotating L-shaped rod 3. A piston rod 5 is fixedly connected to the drive end of the cylinder 4, causing the cylinder 4 to drive the piston rod 5 to move. The cylinder 4 itself can also move, and the cylinder 4 drives itself and the piston rod 5 to move to both sides respectively. The outer left side of the piston rod 5 is rotatably connected to the inside of the left cylinder 4. The positioning assembly includes a sliding plate 12, which is slidably connected to the outside of the fixed groove plate 7. A clamping arm 13 is fixedly connected to the left side of the sliding plate 12. When the sliding plate 12 moves, it drives the clamping arm 13 to clamp inward, thereby accurately positioning the trolley and ensuring that the trolley is oriented accurately when it enters the rotating track. The connecting rod assembly includes two rotating rods 9. The outer left side of the two rotating rods 9 is rotatably connected to the inside of the left side of the fixed column 8. The outer right side of the two rotating rods 9 is rotatably connected to a long connecting rod 10. The far side of the two long connecting rods 10 is fixedly connected to the near side of the two rotating L-shaped rods 3. The near side of the two rotating L-shaped rods 3 is fixedly connected to a short connecting rod 11. The near side of the two short connecting rods 11 is rotatably connected to the outside of the far side of the two sliding plates 12. The short connecting rod 11 drives the sliding plate 12 to slide outside the fixed groove plate 7.
[0033] Reference Figure 1 , Figure 4A power assembly is fixedly connected to the bottom of the connecting plate 17. Two telescopic plates 23 are fixedly connected to the front and rear sides of the turntable 14. A scale plate 24 is fixedly connected inside the telescopic plate 23. The scale plate 24 is used to calibrate the initial angle. When the initial angle is incorrect, the scale plate 24 is inconsistent with the normally displayed scale. A groove 25 is provided on the outside of the connecting plate 17. The bottom of the telescopic plate 23 can automatically extend and fit into the groove 25 to determine that the rotation is in place. Two connecting rails 22 are fixedly connected to the top of the turntable 14. The power assembly includes an L-shaped support plate 20. The top of the L-shaped support plate 20 is fixedly connected to the bottom of the connecting plate 17. A motor 21 is fixedly connected to the top of the L-shaped support plate 20. The drive end of the motor 21 is fixedly connected to the bottom of the rotating shaft 15.
[0034] Reference Figure 1 , Figure 2 A turntable 14 is fixedly connected to the bottom of the support column 1. The rotation of the turntable 14 drives the connecting rail 22 at the top to dock with the fixed rail 19. A rotating shaft 15 is fixedly connected to the bottom of the turntable 14. A limiting sleeve 16 is fitted on the outside of the rotating shaft 15 to limit the offset of the rotating shaft 15. A connecting plate 17 is fixedly connected to the outside of the limiting sleeve 16. Multiple rail bases 18 are fixedly connected to the outside of the connecting plate 17. The rail bases 18 are used to ensure the stable installation of the fixed rail 19. Two fixed rails 19 are fixedly connected to the top of each of the multiple rail bases 18.
[0035] Working principle: First, wait for the trolley to move to the location close to the device, then start the motor 21. The motor 21 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the turntable 14 to rotate. After rotating to the correct position, the telescopic plate 23 will be inserted into the groove 25. At this time, the motor 21 stops. If the trolley is not directly in front of the clamping arm 13, the motor 21 will continue to start until the trolley is directly in front of the clamping arm 13. At this time, the trolley will continue to travel a certain distance and then the power source will be turned off.
[0036] Next, cylinder 4 is started, which pushes cylinder 4 and piston rod 5 to move to both sides, causing the rotating L-shaped rod 3 to rotate around the inside of the support rod 2. The rotation of the L-shaped rod 3 causes the short connecting rod 11 to move, which in turn causes the outer sliding plate 12 to slide inward on the surface of the fixed groove plate 7. The sliding plate 12 causes the clamping arm 13 to clamp the top of the trolley inward, positioning the trolley, which was originally offset at a certain angle, to be consistent with the angle of the connecting track 22. Then, the trolley is started to dock into the connecting track 22. The motor 21 is started to turn the trolley to the next fixed track 19 and then start the trolley to complete the turning.
[0037] After prolonged use, if the telescopic plate 23 is not fully engaged, the motor 21 may also stop moving. At this time, you can observe the scale on the sliding scale plate 24 on the outside of the telescopic plate 23 that is aligned with the turntable 14. If the numbers change, the device can be recalibrated to ensure the stability and accuracy of the device's operation.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
