The lifting platform 9 descends, causing the first roller conveyor 1 to descend until it aligns with the fourth roller conveyor 7. Empty pallets on the fourth roller conveyor 7 are pushed onto the first roller conveyor 1 manually or by a device, and transport personnel place materials on these empty pallets. The lifting platform 9 then raises the first roller conveyor 1 until it aligns with the third roller conveyor 6. This process is repeated to transport the material pallets 8 from the first roller conveyor 1 to the second roller conveyor 2, thus achieving cross-floor transfer of the material pallets 8.

[0042] The first lifting device includes a lifting platform 9, which is located on the side of the first roller line 1 away from the second roller line 2.

[0043] A guide structure 11 is provided on the side of the first roller conveyor 1 away from the lifting platform 9. The guide structure 11 protrudes upward and is inserted into the guide groove 12 of the material trolley 8.

Multiple guide shafts 13 and bearings 14 are provided on the side of the first roller line 1 away from the lifting platform 9. Each guide shaft 13 is inserted into the corresponding guide groove 12, thereby limiting the material trolley 8 at multiple positions and fixing the material trolley 8 on the first roller line 1.

[0047] Multiple guide shafts 13 and bearings 14 are also spaced apart on the second roller conveyor 2. When the material pallet 8 is transferred from the third roller conveyor 6 to the second roller conveyor 2, each guide shaft 13 on the second roller conveyor 2 inserts into the corresponding guide groove 12 of the material pallet 8 to fix the material pallet 8 on the second roller conveyor 2.

The bearing 14 is a cylindrical body, and a shaft hole 15 is opened on the end face of the bearing 14. The guide shaft 13 extends out from the shaft hole 15. The insertion of the guide shaft 13 into the guide groove 12 can prevent relative displacement between the first roller conveyor 1 and the material trolley 8.

[0049] Example 4

[0050] like Figures 1-7As shown, this embodiment provides a material transfer device across floors, including a first roller conveyor 1 and a second roller conveyor 2 located above the first roller conveyor 1; the entrance 4 of the car 3 faces the first roller conveyor 1, and the exit 5 of the car 3 faces the second roller conveyor 2; the first roller conveyor 1 is connected to a first lifting device, and the second roller conveyor 2 is connected to a second lifting device; the first lifting device is used to send the material pallet 8 into the entrance 4 of the car 3, and the second lifting device is used to send the material pallet 8 out from the exit 5 of the car 3.

[0051] The first lifting device includes a lifting platform 9, which is located on the side of the first roller line 1 away from the second roller line 2.

[0052] The first roller line 1 is provided with a roller line frame 16 on the side away from the lifting platform 9, and multiple rows of roller assemblies 17 are provided in the roller line frame 16.

[0053] Oil baffles 18 are provided on both sides of the roller frame 16, and the oil baffles 18 are parallel to each column of roller assembly 17; a motor 19 is provided near the oil baffles 18, and the output shaft of the motor 19 is connected to the roller frame 16.

[0054] The roller frame 16 is a rectangle with a hollow center. N rows of roller assemblies 17 are arranged inside the roller frame 16, and these N rows of roller assemblies 17 are parallel to each other. The two outermost rollers of each row of roller assemblies abut against the inner wall of the roller frame 16. The N rows of roller assemblies are spaced apart, with N≥2; in this embodiment, N=3 is used as an example. Connectors are provided between adjacent rows of roller assemblies. The connectors can be connecting rods or connecting blocks, and are not limited here.

[0055] Each connector is provided with a guide structure 11, that is, each guide structure 11 is located between two adjacent rows of roller assemblies 17. Multiple connectors can be used to fix N rows of roller assemblies 17. The structure of the first roller line 1 is the same as that of the second roller line 2, the third roller line 6, and the fourth roller line 7.

[0056] Oil baffles 18 are disposed on both sides of the roller line frame 16, and abut against the motor 19, which provides power to the N-row roller assembly 17. Oil flowing through the oil baffles 18 can dissipate heat from the operating motor 19.

[0057] Motor 19 drives N rows of roller assemblies 17 to rotate, thereby transporting material pallets 8 and empty pallets. For example, when the first lifting device drives the first roller conveyor 1 to rise until the first roller conveyor 1 is aligned with the third roller conveyor 6, the N rows of roller assemblies 17 of the first roller conveyor 1 rotate, transporting the material pallets 8 on the first roller conveyor 1 to the third roller conveyor 6 inside the car 3. When the third roller conveyor 6 and the fourth roller conveyor 7 rise with the car 3 to the second floor, the second lifting device drives the second roller conveyor 2 to rise until the second roller conveyor 2 is aligned with the third roller conveyor 6. The N rows of roller assemblies 17 of the third roller conveyor 6 rotate, transporting the material pallets 8 on the third roller conveyor 6 inside the car 3 to the second roller conveyor 2.

[0058] In this embodiment, a roller frame 16 is provided on the side of the first roller conveyor 1 away from the lifting platform 9, and multiple rows of roller assemblies 17 are arranged inside the roller frame 16.

A motor 19 is located near the oil baffles 18, and the output shaft of the motor 19 is connected to the roller frame 16. The motor 19 drives the N rows of roller assemblies 17 to rotate, thereby realizing the transportation of material pallets 8 and empty pallets. For example, when the first lifting device drives the first roller conveyor 1 to rise until the first roller conveyor 1 is aligned with the third roller conveyor 6, the N rows of roller assemblies 17 of the first roller conveyor 1 rotate, transporting the material pallets 8 on the first roller conveyor 1 to the third roller conveyor 6 inside the car 3.

[0059] Example 5

[0060] like Figures 1-7 As shown, this embodiment provides a material transfer device across floors, including a first roller conveyor 1 and a second roller conveyor 2 located above the first roller conveyor 1; the entrance 4 of the car 3 faces the first roller conveyor 1, and the exit 5 of the car 3 faces the second roller conveyor 2; the first roller conveyor 1 is connected to a first lifting device, and the second roller conveyor 2 is connected to a second lifting device; the first lifting device is used to send the material pallet 8 into the entrance 4 of the car 3, and the second lifting device is used to send the material pallet 8 out from the exit 5 of the car 3.

[0061] Both the entrance 4 and the exit 5 of the car 3 are provided with height-limiting frames 20. The height of the height-limiting frames 20 is less than or equal to the height of the entrance 4 of the car 3. The height-limiting frames 20 are used to limit the height of the material on the material tray 8.

[0062] The line lifting frame assembly 10 includes a hydraulic cylinder 21 and a lifting frame frame 22. The hydraulic cylinder 21 is connected to a pulley 23. A plate chain 24 is located on the side of the pulley 23 away from the hydraulic cylinder 21. The first end of the plate chain 24 is fixed to the lifting frame frame 22, and the second end of the plate chain 24 is fixed to the side of the second roller line 2.

[0063] The height restriction frame 20 is a gantry support. Material is placed on the material tray 8. The height restriction frame 20 is set at both the entrance 4 and the exit 5 of the car 3 to limit the height of the material on the material tray 8. This prevents the material tray 8 with too much material from passing through the entrance 4 and the exit 5 of the car 3. In other words, it restricts the material tray 8 with too much material from entering the car 3 from the entrance 4 and exiting the car 3 from the exit 5.

[0064] A first fixed plate is connected to the middle of the lifting frame 22, and a second fixed plate is connected to the first fixed plate. A slide rail 25 is connected to the side of the second fixed plate away from the first fixed plate, and a slider is connected to the slide rail 25. The slide rail 25 and the slider are used to limit the movement of the second roller conveyor 2 in the horizontal plane. The first end of the plate chain 24 is fixed to the lifting frame 22, and the second end of the plate chain 24 is fixed to the side of the second roller conveyor 2. The hydraulic cylinder 21 controls the rising and falling of the second roller conveyor 2 through the pulley 23 and the plate chain 24.

[0065] The hydraulic cylinder 21 provides the rotational power for the pulley 23. When the pulley 23 rotates clockwise, the chain 24 drives the second roller 2 to rise, aligning it with the third roller 6 at the same height. The third roller 6 transports the material pallet 8 onto the second roller 2. When the pulley 23 rotates counterclockwise, the chain 24 drives the second roller 2 to fall, aligning it with the fourth roller 7 at the same height. The second roller 2 moves the material pallet 8 towards the slope, where it enters and moves along the slope until it lands on the receiving surface, where personnel remove it.

[0066] In this embodiment, both the entrance 4 and the exit 5 of the car 3 are equipped with height-limiting frames 20. The height of the height-limiting frames 20 is less than or equal to the height of the entrance 4 of the car 3. The height-limiting frames 20 are used to limit the height of the material on the material tray 8. The line lifting frame assembly 10 includes a hydraulic cylinder 21 and a lifting frame 22. The hydraulic cylinder 21 is connected to a pulley 23. A plate chain 24 is located on the side of the pulley 23 away from the hydraulic cylinder 21. The first end of the plate chain 24 is fixed to the lifting frame 22, and the second end of the plate chain 24 is fixed to the side of the second roller line 2. The height-limiting frame 20 is a gantry support. Material is placed on the material tray 8. The height-limiting frames 20 installed at both the entrance 4 and the exit 5 of the car 3 can limit the height of the material on the material tray 8, preventing the material tray 8 with excessive material from passing through the entrance 4 and the exit 5 of the car 3. The first end of the plate chain 24 is fixed to the lifting frame 22, and the second end of the plate chain 24 is fixed to the side of the second roller line 2. The hydraulic cylinder 21 controls the rise and fall of the second roller line 2 through the pulley 23 and the plate chain 24.
