Description

Technical Field

[0001] This utility model relates to the field of RGV vehicle technology, and in particular to a rail shuttle transport vehicle and its conveying system. Background Technology

[0002] With the rapid development of automated warehousing and logistics systems, rail-guided vehicles (RGVs) are being used more and more widely in industrial production and logistics transportation. As a highly efficient and stable automated transportation device, RGVs can automatically run on fixed tracks to complete the task of transporting materials or products, greatly improving production efficiency and the level of logistics automation.

[0003] Existing RGV track designs mainly include two types: linear reciprocating tracks and circular tracks. Linear reciprocating tracks have a simple structure and are suitable for round-trip transportation between two points, while circular tracks enable continuous multi-point transportation and are suitable for more complex transportation scenarios. However, both track designs have certain limitations in flexibility, especially when the RGV needs to switch between different tracks. Currently, some RGVs with steering functions achieve track switching through dedicated track-changing devices (such as turnouts or turntables). This track-changing method requires specialized mechanical structures, and the RGV must stop and wait for the track-changing device to complete its operation during track switching. The entire process is time-consuming, thus affecting overall transportation efficiency and production line cycle time.

[0004] In practical applications, especially in high-paced production environments, excessively long track-changing times can lead to decreased RGV transport efficiency and may even become a bottleneck in the logistics system. Furthermore, the maintenance and failure rate of dedicated track-changing devices can also impact system stability. Therefore, there is still room for improvement in existing RGV track design and track-changing mechanisms to enhance logistics system efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a rail-guided shuttle transport vehicle and conveying system to alleviate the technical problem that the existing technology has a dedicated rail-changing device for the RGV trolley to perform rail-changing operations, which takes a long time and affects production efficiency.

[0006] In the first aspect, the rail shuttle vehicle provided by this utility model includes: a shuttle vehicle body, a drive component, a rotating shaft, and a reversing guide wheel;

[0007] The main body of the shuttle car is used to move in the track, and guide edges are provided on the top of both side walls of the track;

[0008] The driving component is mounted on the main body of the shuttle, and the driving component is connected to the rotating shaft in a transmission manner;

[0009] The reversing guide wheel is connected to the rotating shaft, and the rotation axis of the reversing guide wheel is perpendicular to the axis of the rotating shaft;

[0010] The driving component is configured to drive the rotating shaft to rotate along its own axis, so that the rotation axis of the reversing guide wheel switches between a vertical position and a horizontal position.

[0011] When the rotation axis of the reversing guide wheel is in a vertical position, the reversing guide wheel abuts against the guide edge.

[0012] In an optional implementation,

[0013] The guide edge is arranged vertically so that when the reversing guide wheel contacts the guide edge, the wheel diameter of the reversing guide wheel is perpendicular to the guide edge.

[0014] In an optional implementation,

[0015] The top of both sides of the track has a connecting plate arranged in a horizontal direction, and the connecting plate extends into the track.

[0016] Each of the connecting plates is connected to the guide edge at the end furthest from the track sidewall.

[0017] In an optional implementation,

[0018] The drive component is configured to drive the rotating shaft to rotate according to the scheduling command, so as to drive the reversing guide wheel to flip.

[0019] In an optional implementation,

[0020] The drive component and the rotating shaft are provided on both sides of the main body of the shuttle.

[0021] In an optional implementation,

[0022] The rail shuttle vehicle also includes a gearbox;

[0023] The gearbox is provided on both sides of the main body of the shuttle, and the gearbox is connected to the drive component located on the same side.

[0024] In an optional implementation,

[0025] The rail shuttle vehicle also includes a mounting plate;

[0026] The mounting plate is connected to the main body of the shuttle, the gearbox is connected to one side of the mounting plate, and the rotating shaft passes through the mounting plate and is connected to the gearbox.

[0027] In an optional implementation,

[0028] One or more reversing guide wheels are fixedly installed on each of the rotating shafts.

[0029] Secondly, the conveying system provided by this utility model includes a track and the rail shuttle vehicle;

[0030] The shuttle body (100) is provided with guide wheels (110) on both sides, and the guide wheels (110) are used to abut against the side wall of the track (10);

[0031] The top of the shuttle body (100) has a tray (120) for transporting goods, and the guide edge (11) is positioned no higher than the tray (120). In an optional embodiment,

[0032] The track has at least three branching points.

[0033] The rail-guided shuttle vehicle provided by this utility model uses the driving force generated by the driving component set on the main body of the shuttle vehicle to drive the rotating shaft to rotate along its own axis. The reversing guide wheel on the rotating shaft rotates together with the rotating shaft, so that the reversing guide wheel can rotate and move. The rotation axis of the reversing guide wheel switches between vertical and horizontal positions. When the rotation axis of the reversing guide wheel is in the vertical position, the reversing guide wheel abuts against the guide edge at the top of the track. Thus, by using the reversing guide wheel to roll in the guide edge, the main body of the shuttle vehicle moves along the guide edge in contact with the reversing guide wheel, and the direction of movement of the main body of the shuttle vehicle in the track is adjusted. This alleviates the technical problem of the long track changing time and the impact on production efficiency caused by the existing dedicated track changing device for RGV trolley track changing operation.

[0046] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0047] like Figure 1 , Figure 4 and Figure 7 As shown, the rail-guided shuttle vehicle provided in this embodiment includes: a shuttle body 100, a drive component 200, a rotating shaft 300, and a reversing guide wheel 400; the shuttle body 100 moves in the track 10, and guide edges 11 are provided on the top of both side walls of the track 10; the drive component 200 is disposed on the shuttle body 100, and the drive component 200 is connected to the rotating shaft 300 in a transmission manner, and the driving force generated by the drive component 200 acts on the rotating shaft 300, so that the rotating shaft 300 can rotate along its own axis.

[0048] The reversing guide wheel 400 is connected to the rotating shaft 300. The reversing guide wheel 400 is fixedly mounted on the rotating shaft 300, and the rotation axis of the reversing guide wheel 400 is perpendicular to the axis of the rotating shaft 300. The rotating shaft 300 rotates along its own axis, causing the reversing guide wheel 400 to rotate together.

[0049] The drive component 200 is configured to drive the rotating shaft 300 to rotate along its own axis, so that the rotation axis of the reversing guide wheel 400 can rotate between the vertical and horizontal positions. When the rotation axis of the reversing guide wheel 400 is in the vertical position, the reversing guide wheel 400 abuts against the guide edge 11, so that the entire shuttle body 100 can move in a different direction under the traction of the guide edge 11.

[0050] In addition, the guide edge 11 located at the top of the track 10 can not only achieve the function of changing tracks, but also prevent the vehicle from tilting or bouncing due to centrifugal force when cornering at high speed.

[0051] It should be noted that the track 10 serves as the driving track, providing a stable moving path for the shuttle body 100, while the guide edge 11 serves as a track-changing structure, set at intersections or junctions to enable vehicles to travel straight or diverge / merge.

[0052] The rail-guided shuttle vehicle provided in this embodiment uses the driving force generated by the driving component 200 on the main body 100 of the shuttle vehicle to drive the rotating shaft 300 to rotate along its own axis. The reversing guide wheel 400 on the rotating shaft 300 rotates together with the rotating shaft 300, so that the reversing guide wheel 400 can rotate and move, and the rotation axis of the reversing guide wheel 400 switches between vertical and horizontal positions. When the rotation axis of the reversing guide wheel 400 is in the vertical position, the reversing guide wheel 400 abuts against the guide edge 11 at the top of the track 10, so that the main body 100 of the shuttle vehicle moves along the guide edge 11 in contact with the reversing guide wheel by rolling the reversing guide wheel in the guide edge 11, and adjusts the direction of movement of the main body 100 of the shuttle vehicle in the track 10. This alleviates the technical problem of the long track changing time and the impact on production efficiency caused by the dedicated track changing device for RGV vehicles in the prior art.

[0053] Based on the above embodiments, in an optional implementation, the guide edge 11 in the rail shuttle vehicle provided in this embodiment is arranged in a vertical direction so that when the reversing guide wheel 400 contacts the guide edge 11, the wheel diameter of the reversing guide wheel 400 is perpendicular to the guide edge 11.

[0054] Specifically, when it is necessary to turn to one side, the drive component 200 near the turning side works, driving the rotating shaft 300 to rotate, so that the reversing guide wheel 400 on the rotating shaft 300 abuts against the guide edge 11 on the reversing side. At this time, the reversing guide wheel 400 can roll on the surface of the guide edge 11, thereby pulling the shuttle body 100 to turn and change direction through the cooperation between the reversing guide wheel 400 and the guide edge 11.

[0055] In an optional embodiment, in order to connect the guide edge 11, the top of both side walls of the track 10 have a connecting plate 12 arranged in a horizontal direction, and the connecting plate 12 extends into the track 10; the end of each connecting plate 12 away from the side wall of the track 10 is connected to the guide edge 11, the guide edge 11 is arranged in a vertical direction, and the guide edge 11 and the connecting plate 12 are perpendicular to each other.

[0056] In an optional embodiment, a drive component 200 and a rotating shaft 300 are provided on both sides of the shuttle body 100, and a reversing guide wheel is provided on both sides of the shuttle body 100.

[0057] In an optional embodiment, the drive component 200 is configured to drive the rotating shaft 300 to rotate according to the scheduling command, so as to drive the reversing guide wheel 400 to flip.

[0058] Specifically, when the shuttle car body 100 travels on the track 10 to the junction / separation point, it needs to enter the curve according to the dispatching instructions. At this time, the reversing guide wheel 400 on the shuttle car body 100 flips upward and contacts the guide edge 11 of the track 10. Under the constraint of the guide edge 11, the shuttle car body 100 enters the curve and separates from the track. Meanwhile, the reversing guide wheel 400 on the other side of the shuttle car body 100 is not flipped.

[0059] In an optional embodiment, the rail shuttle vehicle also includes a gearbox 500; gearboxes 500 are provided on both sides of the shuttle vehicle body 100, and the gearboxes 500 are connected to the drive component 200 located on the same side. The drive component 200 is specifically configured as a drive electrode. When the drive electrode is energized, it drives the gearbox 500, and after speed adjustment, it drives the rotating shaft 300 to rotate.

[0060] In an optional embodiment, the rail shuttle vehicle also includes a mounting plate 600; the mounting plate 600 is connected to the shuttle vehicle body 100, the gearbox 500 is connected to one side of the mounting plate 600, and the rotating shaft 300 passes through the mounting plate 600 and is connected to the gearbox 500.

[0061] In an optional embodiment, one or more reversing guide wheels 400 are fixedly provided on each rotating shaft 300. In order to ensure the stability of the rolling of the reversing guide wheel 400 and the guide edge 11, multiple reversing guide wheels 400 can be provided on the rotating shaft 300.

[0062] The rail shuttle vehicle provided in this embodiment improves vehicle throughput efficiency when multiple vehicles are operating by integrating a reversing and track-changing structure on the main body 100 of the shuttle vehicle, i.e., the RGV trolley. When one vehicle malfunctions, the system can quickly resume operation by directly removing the RGV trolley. Compared with the existing track 10 track-changing system, it eliminates the need for all RGV vehicles to stop and wait for the RGV trolley to recover before continuing operation.

[0063] Based on the above, the conveying system provided in this embodiment includes a track 10 and a rail shuttle vehicle; guide wheels 110 are provided on both sides of the shuttle vehicle body 100. The guide wheels 110 are used to abut against the side wall of the track 10. Specifically, the guide wheels 110 are close to the side wall of the track to prevent the vehicle from shaking when it is moving. The guide wheels 110 are installed in the lower part of the chassis of the shuttle vehicle body 100 to increase driving stability.

[0064] The shuttle body 100 has a tray 120 on its top for transporting goods. The height of the guide edge 11 and the height of the track 10 are not higher than the tray 120. The tray 120 is mounted on the shuttle body 100 via a lifting device, allowing the tray 120 to move up and down relative to the shuttle body 100 for easy transport of goods. When the shuttle body 100 is moving, the tray is lowered to its lowest position, minimizing the distance to the chassis of the shuttle body 100, thus stabilizing the goods when the vehicle is turning or moving, and enabling high-speed turning. In an optional embodiment, the track 10 has at least three branching points, and each branching point has guide edges 11 on both side walls of the track 10. The drive member 200 drives the reversing guide wheel 400 to rotate and move. When a change of direction is needed, the reversing guide wheel 400 is rotated to abut against the guide edge 11 on the side requiring turning. The guide edge 11 pulls the rail shuttle vehicle to turn.

[0065] like Figure 2 , Figure 3 As shown, track 10 is a parallel branching track 10, as... Figure 5 , Figure 6 As shown, track 10 is a three-way branch track 10.

[0066] Since the technical effects of the conveying system provided in this embodiment are the same as those of the rail shuttle vehicle provided in the above embodiments, they will not be described again here.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
