[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] The components in this application, such as frame 1, vehicle body 2, travel track 3, guide pole 4, guide plate 5, winch 6, wire rope 7, fixed frame 8, lifting platform 9, guide wheel 10, guide track 11, support rod 12, rotating frame 13, front guardrail 14, rear guardrail 15, fork arm 16, electric push rod 17, drive motor 18, ball screw 19, moving plate 20, guide vertical rod 21, guide table 22, roller 23, ball nut 24, and lifting plate 25, are all general standard parts or parts known to those skilled in the art. Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0020] Please see Figures 1-4This utility model provides a technical solution: a lifting device for logistics warehousing, including a frame 1, a winch 6 fixedly installed at the top of the inner cavity of the frame 1, a wire rope 7 fixedly installed at the middle end of the winch 6, a fixed frame 8 fixedly installed at the bottom of the wire rope 7, a lifting platform 9 fixedly installed at the bottom of the fixed frame 8, a drive motor 18 fixedly installed at the back of the lifting platform 9, a ball screw 19 fixedly installed at the output end of the drive motor 18, a ball nut 24 connected to the surface of the ball screw 19, and a movable plate 20 fixedly installed on the surface of the ball nut 24. Fork arms 16 are fixedly installed on both sides of the lifting platform 9. A rear guardrail 15 is fixedly installed on the top of the lifting platform 9. Rotating frames 13 are movably connected to the middle of both sides of the fixed frame 8 via bearings. A front guardrail 14 is fixedly installed between the bottoms of the two rotating frames 13 and in front of the rear guardrail 15. A support rod 12 is hinged to the middle of the top of the rotating frame 13 via a pin. A lifting plate 25 is hinged between the upper ends of the two support rods 12 via a pin. An electric push rod 17 is fixedly installed at the middle of the lifting plate 25. The output end of the electric push rod 17 is fixedly installed at the middle of the top of the fixed frame 8.

[0021] In this technical solution, when goods need to be moved on the automated storage and retrieval system, the extension of the electric push rod 17 can push the lifting plate 25 upward. Simultaneously, the lifting plate 25 can pull the rotating frame 13 and the front guardrail 14 to rotate via the support rod 12 until the front guardrail 14 can be opened from the front of the lifting platform 9. Then, the external controller starts the drive motor 18, which drives the ball screw 19 to rotate, causing the ball nut 24, the moving plate 20, and the fork arm 16 to move forward, allowing the fork arm 16 to insert into the pallet at the bottom of the goods. Subsequently, the winch 6 works to wind up the wire rope 7, pulling the fixed frame 8 and the lifting platform 9. The fork arm 16 moves upward to lift the goods off the shelf. Then, the drive motor 18 is started to reverse, causing the fork arm 16 to move backward until the goods are above the lifting platform 9. Subsequently, the electric push rod 17 is operated to retract, causing the lifting plate 25 to move downward. This pushes the rotating frame 13 and the front guardrail 14 to rotate through the support rod 12 until the front guardrail 14 is in front of the goods. Thus, the cooperation between the front guardrail 14 and the rear guardrail 15 can effectively protect the area around the goods, preventing them from slipping off the lifting platform 9 due to shaking during subsequent movement and handling, effectively improving the safety of the operation.

[0022] It should be noted that the ball nut 19 and the ball screw 24 require regular maintenance by personnel during use.
