Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Referring to Figures (1-3), a lifting platform for prefabricated building construction includes a bottom lifting plate 1, a middle lifting plate 4, and a top lifting plate 5. The bottom lifting plate 1, the middle lifting plate 4, and the top lifting plate 5 are mounted on a support frame composed of four support columns 2 and multiple support side rods 3. The bottom lifting plate 1 has a first sliding groove 11 at its top. The middle lifting plate 4 is positioned above the bottom lifting plate 1 and has a second sliding groove 41 that runs through the top and bottom of the middle lifting plate 4. The top lifting plate 5 is positioned above the middle lifting plate 4 and has a third sliding groove 51 at its bottom. Moving blocks 6 are slidably arranged in the first sliding groove 11, the second sliding groove 41, and the third sliding groove 51. Moving blocks 6 on adjacent lifting plates are connected by lifting rods 61.

[0018] The outer wall of the support column 2 is provided with support screw holes 21. The two ends of the support side rod 3 are provided with screw holes and fixed bolts 31 are screwed on. The fixed bolts 31 can be screwed into the support screw holes 21. The bottom of the bottom lifting plate 1 is provided with screw holes. The bottom of the four support columns 2 is provided with support plates 22, and bolts are screwed on the support plates 22. The bolts can be screwed into the screw holes at the bottom of the bottom lifting plate 1. The middle lifting plate 4 and the top lifting plate 5 are slidably connected to the support columns 2.

[0019] A lifting screw 12 is rotatably disposed in the first slide groove 11. A first bevel gear 13 is disposed on the lifting screw 12. A transmission shaft 14 is rotatably disposed in the bottom lifting plate 1. A second bevel gear 15 is disposed at both ends and in the middle of the transmission shaft 14. The second bevel gear 15 at both ends meshes with the first bevel gear 14. The second bevel gear 15 in the middle meshes with a third bevel gear 16 in the bottom lifting plate 1. The third bevel gear 16 is connected to the output end of a drive motor 17 disposed in the bottom lifting plate 1.

[0020] A lifting screw 12 is rotatably mounted within the second slide groove 41. A first bevel gear 13 is mounted on the lifting screw 12. A drive shaft 14 is rotatably mounted within the middle lifting plate 4. Second bevel gears 15 are mounted at both ends and in the middle of the drive shaft 14. The second bevel gears 15 at both ends mesh with the first bevel gear 14, and the second bevel gear 15 in the middle meshes with a third bevel gear 16 within the bottom lifting plate 1. The third bevel gear 16 is connected to the output end of a drive motor 17 located within the middle lifting plate 4. The lifting screw 12 passes through and is screwed onto the moving block 6. A slide rod 52 is mounted within the third slide groove 51. The moving block 6 is slidably connected to the slide rod 6 through the slide rod 52.

[0021] The lifting rod 61 consists of two intersecting long rods rotatably connected at the middle. The two ends of the two long rods are rotatably connected to the movable blocks 6 on two adjacent lifting plates, respectively. The top of the movable blocks 6 on the bottom lifting plate 1, the top and bottom of the movable blocks 6 on the middle lifting plate 4, and the bottom of the movable blocks 6 on the top lifting plate 5 are provided with grooves. The two ends of the long rods of the lifting rod 61 are rotatably set in the grooves and are penetrated by mounting bolts 62. The mounting bolts 62 are rotatably connected to the long rods and screwed with nuts.

[0022] In order for the moving blocks 6 on the same lifting screw 12 to move in opposite directions when the lifting screw 12 rotates, the threads of the lifting screw 12 and the moving blocks 6 at both ends need to be in opposite directions, and the threads of the two lifting screws 12 on the same lifting plate need to be in opposite directions at the same end.

[0023] When using this device, select the number of lifting plates 4 according to the needs. Insert the two ends of the two long rods of the lifting rod 61 into the grooves of the moving blocks 6 on the adjacent lifting plates, and insert the mounting bolts 62 to connect the moving blocks 6 to the long rods. Tighten the nuts to fix them. Then, attach the support plates 22 on the four support columns 2 to the bottom of the bottom lifting plate 1 and connect the support plates 22 to the bottom of the bottom lifting plate 1 with bolts. When it is necessary to lift or lower the workers or materials on the top of the top lifting plate 5, start the drive motor 17 to drive the third bevel gear 16 to rotate. The third bevel gear 16 rotates through the second bevel gear 15 and the transmission shaft 14. The transmission shaft 14 drives the lifting screw 12 to rotate, which in turn drives the moving blocks 6 to move along the first slide groove 11, the second slide groove 41 and the second slide groove 51 to realize the lifting of the lifting plate.
