The servo motor 18 can drive the threaded rod 16 to rotate, thereby making the two fixed rods 302 located directly below 2 moves in opposite directions, so that the two groups of scissor arms 301 can shrink and stretch, and the center of gravity of the construction platform 4 can be kept unchanged during the lifting and lowering process. The scissor-type structure 3 is installed between the base 2 and the construction platform 4. The scissor-type structure 3 is located below the middle of the construction platform 4. The upper surface of the construction platform 4 is fixedly connected with two symmetrical support plates 5. The interiors of the two support plates 5 are rotatably connected with fixed columns 19 that penetrate front and back. Both ends of the two cross bars 6 are rotatably connected with cross plates 20. Both ends of the two fixed columns 19 are rotatably connected with the two groups of cross plates 20.

Two symmetrical The tops of the two multi-section lifting rods 9 are fixedly connected to the middle of the ground of the construction platform 4. The multi-section lifting rod 9 uses the force of the hydraulic system to control the flow of hydraulic oil to achieve lifting. In the multi-section lifting rod 9, the hydraulic oil is transported to the hydraulic cylinder through the hydraulic pump, so that the piston of the hydraulic cylinder moves upward, thereby pushing the telescopic rod to extend upward. The top of the telescopic rod is connected to multiple sections, and these sections can rise upward under the action of the telescopic rod. The sections of the multi-section lifting rod 9 are connected by a support frame, and the support frame has a certain rigidity and strength to ensure the stability and safety of the entire lifting rod.

[0025] When in use, first start the servo motor 18 to drive the threaded rod 16 to rotate, and the threaded rod 16 drives the two sliders 15 to approach each other, and then the two sliders 15 drive the two lowest fixed rods 302 to approach each other, and the two groups of rollers 12 at the top to approach each other, so that the two multi-section lifting rods 9 can cooperate to push the construction platform 4 to rise. At this time, the two scissor-type structures 3 and the construction platform 4 are on the same axial line, which improves the overall stability.

[0026] When goods need to be loaded, the goods need to be placed in two groups of storage boxes 801. The gravity of the storage boxes 801 and the goods can enable the storage mechanism 8 to drive the turntable 7 to rotate around the cross bar 6. When the turntable 7 is rotated to balance, the turntable 7 stops rotating under the action of gravity, so that the two groups of turntables 7 are on the same axis with the cross bar 6 and the construction platform 4, thereby avoiding the center of gravity deviating from the axis when the goods are too heavy, thereby making the lifting platform 1 more stable.
