[0002] When the traditional goods are stacked, a forklift or other lifting equipment is usually used for operation, and the forklift or other lifting equipment needs to be manually turned and forked on site, which is difficult to operate reliably in a small space.

[0003] To solve the above problems, the patent document with publication number "CN221875220U" discloses a stacking robot for logistics storage, which comprises a robot base and an article lifting frame. The top end of the robot base is rotatably connected with a rotating disc, and the top end of the rotating disc is fixed with the article lifting frame. The inside of the article lifting frame is provided with a sliding block which slides in a sliding groove. The bottom end of the sliding groove is fixed with a first motor, and the output end of the first motor drives a first lead screw which is threadedly connected with the sliding block. The side of the sliding block is fixedly connected with a first hydraulic rod, and the output end of the first hydraulic rod is fixed with a cargo box. A discharging mechanism is installed at the cargo box to discharge the goods inside. The inside of the robot base is fixed with a speed reducer, and the output end of the speed reducer is drivingly connected with the rotating disc. The bottom end of the robot base is fixedly installed with sliding wheels close to the four corners, and the bottom end of the robot base is symmetrically fixedly installed with hydraulic support rods, and the output end of the hydraulic support rods is fixedly connected with supporting feet.

[0004] Based on the above search, combined with the prior art, it is found that the existing stacking robot for logistics storage is usually connected only by a hydraulic rod between the cargo box and the liftable sliding plate, and some use a support rod for support and guidance (as recorded in the technical solution disclosed in the patent document with publication number "CN217024487U"). However, under the condition of heavy load of the cargo box, both the hydraulic rod and the support rod bear a large end pressure, so they are prone to fatigue bending after long-term use, which accelerates the wear of the equipment and reduces the service life of the equipment. Therefore, a stacking robot for logistics storage is needed. UTILITY MODEL CONTENTS
