[0013] 1. Equipped with a DC motor screw jack, drive arm, rotating rod, L-shaped swing arm, connecting rod, and support plate, the DC motor screw jack facilitates the deflection of the drive arm, which in turn drives the rotating rod to rotate, causing the L-shaped swing arms at both ends of the rotating rod to swing synchronously. The connecting rod connects the L-shaped swing arms at the ends of the two rotating rods, allowing the two rotating rods to rotate synchronously. The swing of the L-shaped swing arms adjusts the height of their tops, thereby adjusting the height of the support plate and the lifting frame accordingly. This provides height adjustment for the material carrier, facilitating the lifting of the material carrier and the materials transported on top to the appropriate height. This greatly facilitates the unloading of materials by workers or the adaptation to subsequent equipment of different heights, improving the accuracy of material conveying and transporting, and making operation more convenient and faster.

This facilitates adjusting the orientation of the transported material to a suitable angle, ensuring better matching of the material with subsequent equipment. This greatly facilitates the transfer of materials to the equipment, reduces the workload of staff in placing materials, and the limiting bend plate limits the placement of materials, preventing them from tilting to either side and making the movement more stable.
[0015] 3. Equipped with omnidirectional wheels, a travel motor, and directional wheels, the travel motor drives the directional wheels to rotate, enabling the overall movement of the transfer vehicle. The omnidirectional wheels also provide support and guidance, allowing the transfer vehicle to move in both straight lines and curves, making its movement more flexible. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example: Figure 1-5 As shown, this utility model provides a technical solution: a trackless remote-controlled transfer vehicle for cross-workshop chassis, including a base 1. An electrical control box 2 is fixedly installed at the center of one end of the base 1. A mounting seat 3 is fixedly installed at the center of the bottom end of the base 1. A DC motor screw jack 4 is rotatably installed at the bottom of the mounting seat 3. A connector 5 is fixedly connected to the end of the DC motor screw jack 4. A drive arm 6 is rotatably connected to the center of the connector 5. The connector 5 and the drive arm 6 are movably connected via a rotating shaft. The top of the drive arm 6 is fixedly connected to the center of a rotating rod 7. The top of the drive arm 6 is located at the center of a positioning seat 9. Rotating rods 7 are symmetrically mounted at both ends of the bottom of base 1. Fixed seats 8 are rotatably connected to both ends of each rotating rod 7. A positioning seat 9 is rotatably connected to the middle of one rotating rod 7. Both fixed seats 8 and positioning seats 9 are fixedly mounted to the bottom of base 1 with bolts. L-shaped swing arms 10 are fixedly connected to both ends of each rotating rod 7, located on either side of the two fixed seats 8. The rotating rods 7 are connected to the middle of the L-shaped swing arms 10. Connecting rods 11 are symmetrically mounted on both sides of the bottom of base 1. Support plates 12 are rotatably connected to the top of each L-shaped swing arm 10. The number of L-shaped swing arms 10 is [number missing]. Four, with two connecting rods 11 corresponding to the positions of four L-shaped swing arms 10. The bottom ends of the two L-shaped swing arms 10 on the same side are rotatably connected to both ends of the connecting rods 11 via rotating shafts. The top of the L-shaped swing arms 10 moves through the middle of the movable slot 13. Movable slots 13 are symmetrically opened at both ends of the top of the base 1. A lifting frame 14 is fixedly connected between the top ends of the supporting short plates 12. The use of the DC motor screw jack 4 facilitates the deflection of the drive arm 6, which in turn drives the rotating rod 7 to rotate, causing the L-shaped swing arms 10 at both ends of the rotating rod 7 to move in tandem. The connecting rod 11 connects the L-shaped swing arms 10 at the ends of the two rotating rods 7. The two rotating rods 7 rotate synchronously, and the L-shaped swing arms 10 swing to adjust the height of their tops, thereby adjusting the height of the support plate 12 and the lifting frame 14. This also helps to adjust the height of the material tray 17, making it easier to lift the material tray 17 and the material transported on its top to the appropriate height. This greatly facilitates the removal of materials by workers or the adaptation to subsequent equipment of different heights, improves the accuracy of material conveying and transport, and makes the operation more convenient and faster.
[0026] A slewing bearing 15 is rotatably installed in the middle of the lifting frame 14. A connecting plate 16 is fixedly connected to the top of the slewing bearing 15. A material bracket 17 is fixedly installed at the top of the connecting plate 16. Limiting plates 18 are fixedly installed at both ends of the material bracket 17. The slewing bearing 15 drives the connecting plate 16 and the material bracket 17 to rotate, adjusting the direction of the material bracket 17. This makes it easier to adjust the orientation of the transported material to a suitable angle, making the material more compatible with the subsequent equipment. This greatly facilitates the subsequent transfer of materials to the equipment, reduces the workload of the staff in placing materials, and the limiting plates 18 can limit the placement of materials, preventing the materials from tilting to the sides and making the rotation process more stable.
[0027] Universal casters 19 are installed at the four corners of the bottom of the base 1. Two travel motors 20 are symmetrically fixed at the two ends of the middle of the bottom of the base 1. The output shafts of the two travel motors 20 are fixedly connected to the guide wheels 21. The middle of the two guide wheels 21 is fixedly installed with a fixed shaft. The guide wheels 21 are rotatably connected to the bottom of the base 1 through the fixed shaft. The travel motors 20 are connected to the fixed shafts in the middle of the guide wheels 21. The travel motors 20 drive the guide wheels 21 to rotate, realizing the overall movement of the transfer vehicle. The universal casters 19 play a supporting and guiding role, so the transfer vehicle can realize the overall straight and curved movement, making the movement of the transfer vehicle more flexible.
[0028] The working principle and usage process of this utility model are as follows: First, the staff uses the walking motor 20 to drive the directional wheel 21 to drive the transfer vehicle to move, while the universal wheel 19 provides support and guidance. The transfer vehicle moves in a certain straight line and curve until the transfer vehicle moves to the side of the material storage equipment. Then, the height and direction of the material bracket 17 need to be adjusted according to the position and height of the material storage.
[0029] The operator controls the DC motor screw jack 4 to start, extend or retract, causing the drive arm 6 to rotate forward or swing backward, driving a rotating rod 7 to rotate. The L-shaped swing arms 10 at both ends of this rotating rod 7 swing. The bottom end of the L-shaped swing arm 10 is connected to the L-shaped swing arms 10 at both ends of another rotating rod 7 through a connecting rod 11. The connecting rod 11 plays a linkage role, causing the L-shaped swing arms 10 at the ends of the two rotating rods 7 to deflect simultaneously. The deflection of the top end of the L-shaped swing arm 10 pushes the support plate 12 to one side, causing the support plate 12 to move to one side to rise or move to one side to lower. As a result, the lifting frame 14 and the material tray 17 rise or fall, corresponding to the height position of the material. At the same time, the rotation of the slewing bearing 15 drives the material tray 17 to rotate, so that the material tray 17 faces the direction of the material, making it convenient to accurately place the material on the top of the material tray 17. The limiting bending plate 18 limits and blocks the two sides of the material, preventing the material from sliding to the sides.
[0030] Then, the staff remotely controls the transfer vehicle to move the materials to the side of the subsequent workstation equipment in another workshop, realizing the material transfer between workshops. Next, the height and orientation of the material tray 17 are adjusted in the same way as above, so that the material and the subsequent workstation equipment are at the same height and direction, which facilitates the transfer of materials to the equipment for processing.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
