[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0016] Example 1
[0017] See Figure 1 and Figure 2As shown, this embodiment involves a warehousing and logistics handling vehicle, including an AGV vehicle body 2 with a loading platform 1 on top. The loading platform 1 is provided with a guardrail 3 near its edge. The loading platform 1 is provided with a lifting mechanism surrounded by the guardrail and used to control the lifting of materials. The lifting mechanism includes two bidirectional lead screws rotatably connected to the AGV vehicle body 2 and arranged horizontally on their axes. The bidirectional lead screws include a first lead screw 4 and a second lead screw 5 with opposite rotation directions. A first lead screw nut 6 is threaded onto the first lead screw 4, and a second lead screw nut 7 is threaded onto the second lead screw 5. The loading platform 1 has a working hole 8 that matches the bidirectional lead screws. The working hole 8 is provided with a first fixed hinge plate 9, a first movable hinge plate 10, a second fixed hinge plate 11, and a second movable hinge plate 12. One end of the first fixed hinge plate 9 is hinged to the AGV vehicle body 2, and the other end is hinged to the first movable hinge plate 10. One end of the first movable hinge plate 10, which is not connected to the first fixed hinge plate, is hinged to the first lead screw nut 6. One end of the second fixed hinge plate 11 is hinged to the AGV vehicle body 2, and the other end is hinged to the second movable hinge plate 12. The other end of the second movable hinge plate 12, which is not connected to the second fixed hinge plate, is hinged to the second lead screw nut 7. One end of the bidirectional lead screw is driven and connected to a power assembly that controls rotation. The power assembly includes a linkage shaft 13 that is rotatably connected to the AGV vehicle body 2. The two ends of the linkage shaft 13 are respectively provided with a first bevel gear 14. A second bevel gear 15 meshes with the first bevel gear 14. The second bevel gear 15 is driven and connected to the bidirectional lead screw. A third bevel gear 16 is provided on the linkage shaft 13. A fourth bevel gear 17 meshes with the third bevel gear 16. A motor 18 that controls rotation is driven and connected to the fourth bevel gear 17. The motor 18 is located on the AGV vehicle body 2.
[0018] A first auxiliary block (unmarked) is connected in series between the first lead screw nut 6 and the first movable hinge plate 10. The first auxiliary block is fixedly connected to the first lead screw nut 6, and the first movable hinge plate 10 is rotatably connected to the first auxiliary block.
[0019] A second auxiliary block (unmarked) is connected in series between the second lead screw nut 7 and the second movable hinge plate 12. The second auxiliary block is fixedly connected to the second lead screw nut 7, and the second movable hinge plate 12 is rotatably connected to the second auxiliary block.
[0020] In this embodiment, the motor 18 drives the bidirectional lead screw through two sets of bevel gears, causing the lead screw nut to move axially relative to the lead screw. This causes the first lead screw nut 6 to move towards the first fixed hinge plate 9, so that the first fixed hinge plate 9 and the first movable hinge plate 10 close together and lift the material pressed on them. The second lead screw nut 7 moves towards the second fixed hinge plate 11, so that the second fixed hinge plate 11 and the second movable hinge plate 12 close together and lift the material pressed on them.
[0021] The lifting height can be greater than the height of the guardrail.
[0022] Example 2
[0023] See Figure 1 and Figure 2 As shown, the warehousing and logistics handling vehicle involved in this embodiment is further configured, based on embodiment 1, with a first roller sleeve 19 that rotates relative to each other on the hinge shaft of the first fixed hinge plate 9 and the first movable hinge plate 10; and a second roller sleeve 20 that rotates relative to each other on the hinge shaft of the second fixed hinge plate 11 and the second movable hinge plate 12.
[0024] In this embodiment, the first roller sleeve 19 is rotatable relative to the hinge axis of the first fixed hinge plate 9 and the first movable hinge plate 10, and the second roller sleeve 20 is rotatable relative to the hinge axis of the second fixed hinge plate 11 and the second movable hinge plate 12, so that when the first fixed hinge plate 9 and the first movable hinge plate 10 are closed, and when the second fixed hinge plate 11 and the second movable hinge plate 120 are closed, the material can be smoothly lifted.
