Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a transfer vehicle that can realize dual-station conversion. Background Technology

[0002] In modern industrial production, material handling equipment is a crucial component ensuring the efficient operation of production lines. Especially in automated assembly and warehousing logistics, the operational flexibility of transfer vehicles directly impacts overall production efficiency. As manufacturing upgrades towards intelligence and flexibility, single-station transfer equipment is no longer sufficient to meet the demands of multi-process collaborative production. Transfer vehicles capable of dual-station switching are increasingly becoming essential equipment for improving the continuity of production processes. Through precise station switching mechanisms, these devices can rapidly transfer materials or workpieces between different work areas, reducing waiting time during process transitions and providing strong support for large-scale production.

[0003] In existing technologies, traditional single-station transfer vehicles typically employ a structure design with fixed tracks and a single vehicle frame. Their technical principle mainly involves using a drive motor to propel the wheels along a pre-set track, achieving linear material transfer between single workstations. The connection between the frame and the track is usually rigidly fixed, meaning the relative position of the wheels and the track remains constant, and the transfer vehicle's operating range is limited to the workstation area covered by a single track. For power transmission, chain or belt drives are commonly used to transmit motor power to the wheels, enabling the transfer vehicle's movement.

[0004] However, due to the limitations of their structural design, existing traditional single-station transfer carts cannot flexibly switch between different workstations. When production needs change and materials need to be transferred from one workstation to another workstation with a different track, traditional single-station transfer carts can only travel on fixed tracks and cannot cross different track areas to complete material transfer operations. They must rely on manual assistance or other equipment for secondary transfers, which seriously affects the operational flexibility and efficiency of production equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a transfer vehicle that can realize dual-station conversion, aiming to improve the problem of low operating efficiency caused by the difficulty of traditional single-station transfer vehicles in flexibly switching stations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a transfer vehicle capable of dual-station conversion, comprising a main station track, two sets of main station tracks with station conversion tracks vertically arranged on their inner walls, a station vehicle above the main station tracks, a track wheel on the lower surface of the station vehicle, a conversion transport vehicle above the station conversion tracks, the conversion transport vehicle traveling on the station conversion tracks, eight connecting plates fixedly connected to the outer wall of the conversion transport vehicle, four reinforcing plates fixedly connected to the inner wall of the conversion transport vehicle, two bearings on the inner wall of each connecting plate, and an active rocker arm structure on the inner walls of the two connecting plates.

[0007] Furthermore, the active rocker arm structure includes an electric actuator, the outer wall of which is fixedly connected to the outer wall of the reinforcing plate, a second rocker arm fixedly connected to the output end of the electric actuator, a drive shaft fixedly connected to the inner walls of the two bearings, and the inner wall of the second rocker arm fixedly connected to the outer wall of the drive shaft.

[0008] Furthermore, the lower surface of the track wheel is attached to the upper surface of the main workstation track.

[0009] Furthermore, an elastic pad is fixedly connected to the upper surface of the transfer cart, and the lower surface of the workstation cart is attached to the upper surface of the elastic pad.

[0010] Furthermore, the inner walls of the two connecting plates are provided with a wheel rocker arm structure, the wheel rocker arm structure includes a traveling wheel, the outer wall of the traveling wheel is provided on the inner wall of the transfer and transport vehicle, the inner walls of the two bearings are fixedly connected with a driven shaft, the outer wall of the driven shaft is fixedly connected with a rocker arm, and the outer wall of the driven shaft is fixedly connected with a locking gear.

[0011] Furthermore, the outer wall of the traveling wheel is rotatably connected to the inner wall of the rocker arm, and the lower surface of the traveling wheel is attached to the upper surface of the workstation conversion track.

[0012] Furthermore, a main locking gear is fixedly connected to the outer wall of the drive shaft, and the outer wall of the drive shaft is fixedly connected to the inner wall of the rocker arm.

[0013] Furthermore, the tooth ends of the main locking gear are engaged with the tooth ends of the slave locking gear.

[0014] This utility model has the following beneficial effects: In this invention, the workstation trolley can move flexibly on the main workstation track via the driveway wheels. When a dual-workstation conversion is required, the conversion transport vehicle moves precisely to below the workstation trolley using its traveling wheels on the workstation conversion track. After activating the electric actuator, it pushes the rocker arm two to drive the drive shaft to rotate through the bearing. The main locking gear on the drive shaft meshes with the driven locking gear on the driven shaft, causing the driven shaft to rotate synchronously. Then, by adjusting the position of the traveling wheels through the rocker arm one, the main frame is lifted, and the conversion transport vehicle moves along the workstation conversion track to achieve dual-workstation conversion. This solves the problem that traditional single-workstation transport vehicles are difficult to switch workstations flexibly, and achieves the effect of improving the operational flexibility and efficiency of the equipment.

[0015] In this invention, the synchronous rotation of the drive shaft and the driven shaft ensures consistent movement of the traveling wheels, and the meshing of the main locking gear and the driven locking gear ensures stable power transmission. This allows the transfer vehicle to move stably along the workstation transfer track, reducing swaying and deviation during movement. This achieves the effect of ensuring accurate docking during workstation transfer and improving the continuity and reliability of dual-workstation transfer. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Reference Figures 1-7 This utility model provides an embodiment of a transfer vehicle capable of dual-station conversion, comprising a main station track 1, two sets of main station track 1 with station conversion track 2 vertically arranged on their inner walls, the two sets of main station track 1 being parallel to each other, and the station conversion track 2 being perpendicular to the main station track 1, the upper surface height of the station conversion track 2 being 20 mm higher than the upper surface height of the main station track 1. Millimeters, a workstation trolley 3 is set above the main workstation track 1. The main workstation track 1 serves as the travel track for the workstation trolley 3, providing a stable support foundation for the workstation trolley 3. The lower surface of the workstation trolley 3 is equipped with a track wheel 5, which can roll along the main workstation track 1. A transfer transport vehicle 4 is set above the workstation transfer track 2. The transfer transport vehicle 4 travels on the workstation transfer track 2, which serves as the travel track for the transfer transport vehicle 4, ensuring that the transfer transport vehicle 4 moves along its trajectory during workstation switching. Eight connecting plates 16 are fixedly connected to the outer wall of the transfer transport vehicle 4, and four reinforcing plates 17 are fixedly connected to the inner wall of the transfer transport vehicle 4. Two bearings 8 are set on the inner wall of each connecting plate 16, and an active rocker arm structure is set on the inner wall of two connecting plates 16.

[0020] Specifically, the connecting plate 16 is used to fix the bearing 8, the reinforcing plate 17 can enhance the structural strength of the conversion transport vehicle 4, the bearing 8 is used to ensure the smooth rotation of shaft components, the main workstation rail 1 is used for the workstation vehicle 3 to move through the rail wheel 5, the conversion transport vehicle 4 travels on the workstation conversion rail 2, and when a dual workstation conversion is required, the conversion transport vehicle 4 moves to below the workstation vehicle 3 through the workstation conversion rail 2.

[0021] Reference Figures 1-7The active rocker arm structure includes an electric actuator 15, whose outer wall is fixedly connected to the outer wall of the reinforcing plate 17. A second rocker arm 12 (elliptical in shape, with one end connected to the electric actuator 15 and the other end connected to the drive shaft) is fixedly connected to the output end of the electric actuator 15. The second rocker arm 12 differs from existing structures. The electric actuator 15 serves as the power source, and its extension and retraction motion drives the second rocker arm 12 to rotate, providing driving force for the entire conversion mechanism. A drive shaft 13 is fixedly connected to the inner walls of two bearings 8. The drive shaft 13 serves as the core component for power transmission. 2. The inner wall is fixedly connected to the outer wall of the drive shaft 13. The rocker arm 12 can drive the drive shaft 13 to rotate synchronously by rotation. The lower surface of the track wheel 5 is attached to the upper surface of the main workstation track 1 to ensure stable contact between the workstation 3 and the main workstation track 1. The upper surface of the transfer vehicle 4 is fixedly connected to an elastic pad 7. The elastic pad 7 plays a buffering and shock-absorbing role when the transfer vehicle 4 lifts the workstation 3. The lower surface of the workstation 3 is attached to the upper surface of the elastic pad 7. The inner walls of the two connecting plates 16 are provided with a wheel rocker arm structure, which includes a traveling wheel 6. The wheels 6 can roll along the workstation transfer rail 2. The outer wall of the wheels 6 is set on the inner wall of the transfer vehicle 4. The driven shaft 14 is fixedly connected to the inner wall of the two bearings 8. The driven shaft 14 rotates synchronously with the drive shaft 13 under the meshing action of the main locking gear 10 and the driven locking gear 11. The outer wall of the driven shaft 14 is fixedly connected to a rocker arm 9 (the rocker arm 9 is a connecting plate structure, one end of which is connected to the drive shaft 13, and the other end is connected to the wheels 6). The structure of the rocker arm 9 is different from that in the prior art. The rocker arm 9 can rotate with the drive shaft 13 and adjust its travel by changing its own angle. At the height position of wheel 6, a driven locking gear 11 is fixedly connected to the outer wall of driven shaft 14. The outer wall of traveling wheel 6 is rotatably connected to the inner wall of rocker arm 9. The lower surface of traveling wheel 6 is in contact with the upper surface of station conversion rail 2. A main locking gear 10 is fixedly connected to the outer wall of drive shaft 13. The outer wall of drive shaft 13 is fixedly connected to the inner wall of rocker arm 9. The tooth end of main locking gear 10 meshes with the tooth end of driven locking gear 11. Main locking gear 10 rotates with drive shaft 13 and transmits power to driven locking gear 11, realizing the power linkage between drive shaft 13 and driven shaft 14.

[0022] Specifically, the main workstation rail 1 supports the workstation cart 3, which realizes material transfer within a single workstation area through the track wheels 5. During the dual-workstation conversion, the conversion transport cart 4 moves along the workstation conversion rail 2 via the traveling wheels 6 to directly below the workstation cart 3. The lower surface of the workstation cart 3 is in contact with the elastic pad 7 of the conversion transport cart 4. The elastic pad 7 provides stable bearing and cushioning. The electric actuator 15 is activated to push the rocker arm 12, which drives the drive shaft 13 to rotate with the help of the bearing 8. The main locking gear 10 of the drive shaft 13 meshes with the driven locking gear 11 of the driven shaft 14, causing the driven shaft 14 to rotate synchronously. Then, the position of the traveling wheels 6 is adjusted by the rocker arm 9, thereby lifting the main frame of the conversion transport cart 4 and separating the workstation cart 3 from the main workstation rail 1. The synchronous rotation of the drive shaft 13 and the driven shaft 14 ensures that the traveling wheels 6 move in unison. The conversion transport cart 4 moves along the workstation conversion rail 2, driving the workstation cart 3 to complete the dual-workstation conversion.

[0023] Working principle: When a transfer vehicle capable of dual-station conversion is needed, the main station rail 1 of the transfer vehicle allows the station vehicle 3 to move via the track wheels 5. When dual-station conversion is required, the conversion transport vehicle 4 moves to below the station vehicle 3 via the walking wheels 6 on the station conversion rail 2. At this time, the lower surface of the station vehicle 3 is in contact with the elastic pad 7 on the conversion transport vehicle 4. The electric push rod 15 is activated to push the rocker arm 12, which drives the drive shaft 13 to rotate via the bearing 8. The main locking gear 10 on the drive shaft 13 meshes with the driven locking gear 11 on the driven shaft 14, causing the driven shaft 14 to rotate synchronously. Then, the position of the walking wheels 6 is adjusted by the rocker arm 9 to lift the main frame and prepare for the station switching of the station vehicle 3. Furthermore, during the conversion process, the synchronous rotation of the drive shaft 13 and the driven shaft 14 ensures that the walking wheels 6 move in unison, causing the conversion transport vehicle 4 to move along the workstation conversion track 2, thereby driving the workstation vehicle 3 above to move and realize the conversion between the two workstations.

[0024] 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.
