Technical Field

[0001] This invention relates to the field of warehousing and transportation technology, specifically to a segmented lifting four-way shuttle vehicle. Background Technology

[0002] Warehousing and logistics involves utilizing self-built or leased warehouses and sites for the storage, safekeeping, loading, unloading, and distribution of goods. The transportation of goods within a warehouse requires the coordinated use of various types of machinery, such as forklifts, conveyor belts, and shuttle vehicles.

Therefore, they should not be construed as limitations on this invention.

[0031] Example:

[0032] Please see Figure 1-7 The present invention provides a technical solution:

[0033] A segmented lifting four-way shuttle includes a sub-rail travel assembly, a lifting conversion rail assembly, and a segmented lifting assembly;

[0034] The lifting conversion rail assembly is fixed to the upper end of the sub-rail travel assembly, and the segmented lifting assembly is installed inside the lifting conversion rail assembly and fixedly connected to the upper side of the sub-rail travel assembly;

[0035] The rail travel assembly includes a rail travel motor 1, a planetary reducer wheel 2, a rail frame assembly 3, and a driven wheel 4;

[0036] The lifting conversion rail assembly includes a lifting motor 5, a reduction gearbox 6, a coupling 7, a drive shaft 8, a lifting gear 9, a lifting rack 10, a lifting connecting block 11, a lifting slide rail 12, a lifting slider 13, a main rail travel motor 14, a main rail planetary reduction wheel 15, and a main rail driven wheel 16.

[0037] The segmented lifting assembly includes a lead screw motor 17, a left-hand lead screw 18, a bearing housing 19, a left-hand lead screw nut 20, a first lead screw jack base plate 21, a right-hand lead screw 22, a right-hand lead screw nut 23, a second lead screw jack base plate 24, a slide rail 25, a slider 26, a lifting motor 27, a telescopic universal joint 28, and a lead screw jack 29.

[0038] There are two subrail travel motors 1, which are fixedly connected to the inner wall of the subrail frame assembly 3. The two subrail travel motors 1 are arranged diagonally opposite each other. The output end of each subrail travel motor 1 is fixed with a planetary reducer wheel 2. The side wall of the subrail frame assembly 3 is rotatably connected to a driven wheel 4 on one side of the planetary reducer wheel 2. The two diagonally arranged subrail travel motors 1 and planetary reducer wheels 2 provide power, and the remaining wheels are driven wheels 4, which follow the movement and travel in two directions along the subrail.

[0039] There are two gearboxes 6, both fixedly connected to the upper side of the subrail frame assembly 3. A lifting motor 5 is fixed to the side wall of the gearbox 6 located at the right end. A coupling 7 is fixed to the side of the two gearboxes 6 that are close to each other. A drive shaft 8 is fixed between the two couplings 7. A lifting gear 9 is fixed to the side of the two gearboxes 6 that are opposite to each other. A lifting rack 10 is meshed on the side wall of the lifting gear 9.

A lifting connecting block 11 is fixed to the upper left and right ends of the two lifting sliders 13. A main rail travel motor 14 is fixed to the inner wall of the two lifting sliders 13. A main rail planetary reduction wheel 15 is fixed to the output end of the main rail travel motor 14. A main rail driven wheel 16 is rotatably connected to the outer wall of the lifting slider 13 next to the main rail planetary reduction wheel 15.

[0040] The two main rail planetary reduction gears 15 are arranged diagonally opposite each other.

[0041] Loading and rail changing actions: The rotation of the lifting motor 5 drives the reduction gearbox 6 to rotate, which in turn drives the lifting gear 9 connected to it to rotate, thereby driving the lifting rack 10 to rise or fall. When the lifting rack 10 rises, it performs the loading action; when the lifting rack 10 falls, it performs the rail changing action. At the rail changing position, the main rail wheel is placed on the rail, and the sub-rail wheel leaves the rail, thereby realizing the main rail travel.

[0042] Subrail travel: Two main rail travel motors 14 are arranged diagonally opposite each other to provide travel power and drive the main rail planetary reduction wheel 15 to rotate. The remaining wheels are main rail driven wheels 16, which follow the movement and travel in two directions along the main rail.

[0043] The segmented lifting assembly includes a lead screw motor 17, a left-hand lead screw 18, a bearing housing 19, a left-hand lead screw nut 20, a first lead screw jack base plate 21, a right-hand lead screw 22, a right-hand lead screw nut 23, a second lead screw jack base plate 24, a slide rail 25, a slider 26, a lifting motor 27, a telescopic universal joint 28, and a lead screw jack 29;

[0044] The lead screw motor 17 is fixedly connected to the upper side of the subrail frame assembly 3. Bearing seats 19 are fixed to both the left and right ends of the lead screw motor 17 on the upper side of the subrail frame assembly 3. A left-hand lead screw 18 and a right-hand lead screw 22 are fixed to the left and right ends of the lead screw motor 17, respectively. The walls of the left-hand lead screw 18 and the right-hand lead screw 22 are threadedly connected to a left-hand lead screw nut 20 and a right-hand lead screw nut 23, respectively. The lower sides of both the left-hand lead screw nut 20 and the right-hand lead screw nut 23 are connected to the upper side of the subrail frame assembly 3. The sliding connection is provided, with a first screw jack seat plate 21 and a second screw jack seat plate 24 fixed to the upper sides of the left-hand screw nut 20 and the right-hand screw nut 23, respectively; symmetrical screw jacks 29 are fixed to the upper sides of both the first screw jack seat plate 21 and the second screw jack seat plate 24; telescopic universal joints 28 are fixed to the side of the first screw jack seat plate 21 and the second screw jack seat plate 24 that are close to each other; and a lifting motor 27 is fixed between the two telescopic universal joints 28.

[0045] There are four slide rails 25, all of which are fixedly connected to the upper side of the sub-rail frame assembly 3. A slider 26 is slidably connected to the outside of the slide rail 25. The upper side of the slider 26 is fixedly connected to the lower side of the first screw jack base plate 21 and the second screw jack base plate 24.

[0046] Working principle: The lead screw motor 17 provides power, driving the left-hand lead screw 18 and the right-hand lead screw 22 to rotate. The left-hand lead screw nut 20 and the right-hand lead screw nut 23 move. When the lead screw motor 17 rotates forward, the left-hand lead screw nut 20 and the right-hand lead screw nut 23 move outward. When the lead screw motor 17 rotates in reverse, the left-hand lead screw nut 20 and the right-hand lead screw nut 23 move inward. The first lead screw jack base plate 21 and the second lead screw jack base plate 24 move with the left-hand lead screw nut 20 and the right-hand lead screw nut 23. After the first lead screw jack base plate 21 and the second lead screw jack base plate 24 are adjusted to a suitable distance from the pallet, the lifting motor 27 rotates, driving the lead screw jack 29 to rise and lift the top plate through the telescopic universal joint 28 to lift the goods.

[0047] The upper ends of the two lifting connecting blocks 11 are jointly fixed with a first top plate 30, and a symmetrical second top plate 31 and a third top plate 32 are respectively provided on both sides of the first top plate 30.

[0048] The four-way shuttle travels along the main rail to different sub-rails, then switches rails to enter the sub-rail channels for picking up and placing goods. Based on sensor perception and information from the upper-level system, it determines the size of the pallet and lifts the corresponding top plate according to the pallet size. The first top plate 30 is lifted by a gear rack and pinion mechanism for rail switching. The second top plate 31 and the third top plate 32 are lifted by switching the screw jack 29 to the corresponding position through the segmented lifting assembly.
