[0027] Please see Figure 1 and Figure 2A modular floor slab hoisting device for house renovation includes: a hoisting horizontal plate 1, a base frame 2, and a hoisting movable plate 6. The base frame 2 is installed at the bottom of the hoisting horizontal plate 1, and an electric slide rail 3 is embedded in the bottom of the hoisting horizontal plate 1. A main top plate 4 is installed at the output end of the electric slide rail 3, and an electric telescopic rod 5 is installed at the bottom of the main top plate 4. The hoisting movable plate 6 is installed at the output end of the electric telescopic rod 5, and a hook chain 7 is installed at the bottom of the hoisting movable plate 6. A hook lock body 8 is installed at the bottom of the hook chain 7. First, the modular floor slab is placed between the base frames 2. Then, the electric telescopic rod 5 operates to drive the hoisting movable plate 6 to move downwards, and the hook lock body 8 is used to hook up the floor slab, thereby lifting and suspending the floor slab. The electric slide rail 3 operates to drive the main top plate 4 to move, which in turn drives the hook lock body 8 to move, thus transporting the floor slab to the designated location.

[0028] Please see Figure 2 and Figure 3 The bottom of the hoisting movable slab 6 is equipped with a receiving mechanism for catching the slab when it falls. The receiving mechanism includes a connecting rod 9 and a receiving frame 10. The connecting rod 9 is installed at the bottom of the hoisting movable slab 6, and the receiving frame 10 is installed at the bottom of the connecting rod 9. The top of the receiving frame 10 has a mounting screw groove 13. An mounting plate 11 is installed on the outer wall of the connecting rod 9, and a mounting screw 12 is installed on the outer wall of the mounting plate 11, with one end of the mounting screw 12 extending into the mounting screw groove 13. The top of the receiving frame 10 has a receiving groove 14, and the inner wall of the receiving groove 14 has a base plate 15. An assembly screw 16 is installed at the bottom of the base plate 15, and an assembly nut 17 is installed around the outer wall of the assembly screw 16. The outer wall of the receiving frame 10 has an assembly through groove 18, with one end of the assembly through groove 18 extending into the receiving groove 14. A rubber padding layer 19 is installed on the outer wall of the base plate 15. When the slab is being transported in a suspended manner, it may... Since floor slabs sometimes fall during transportation, improvements are needed to address this issue. To catch a falling floor slab, a suitable support frame 10 is selected and moved below the connecting rod 9. The mounting screw 12 is then fixed into the mounting screw groove 13. The support frame 10 is installed below the connecting rod 9, and the connecting rod 9 moves with the hoisting moving plate 6, while the support frame 10 follows the connecting rod 9. This ensures that the support frame 10 always catches the floor slab, regardless of its location. The support frame 10 is equipped with a rubber padding layer 19 to protect the inside of the support groove 14. When the rubber padding layer 19 needs replacement, the assembly nut 17 is rotated out from the outside of the assembly screw 16. Then, the base plate 15 is pulled to remove the assembly screw 16 from the assembly through groove 18, and the base plate 15 is removed from the support groove 14, allowing the rubber padding layer 19 to be removed and replaced.

[0029] Please see Figure 2 , Figure 4 and Figure 5The bottom of the receiving frame 10 is equipped with a tool mechanism for storing commonly used tools. The tool mechanism includes a toolbox 20, which is mounted on the bottom of the receiving frame 10. A slide bar 21 is mounted on the inner wall of the toolbox 20, and a slider 22 is mounted around the outer wall of the slide bar 21. A tool frame 23 is mounted on the bottom of the slider 22, and a tool slot 24 is provided on the top of the tool frame 23. A retrieval slot 25 is provided on the inner wall of the toolbox 20, and a magnetic suction plate 26 is mounted on the outer wall of the tool frame 23 for use during hoisting. Since the device often requires the use of common tools such as wrenches and screwdrivers, the receiving frame 10 has a built-in tool storage function. First, pull the magnetic plate 26 to move it out of the toolbox 20. The toolbox 20 is made of corrosion-resistant iron material. Then, continue pulling to move the tool frame 23 outside the slide bar 21 via the slider 22 and remove it from the toolbox 20 through the retrieval slot 25. At this time, the tools in the tool slot 24 can be taken out and used. After use, the tools can be put back in their original place for storage, which is convenient and quick.

[0030] The working principle is as follows: First, the modular floor slab is placed between the base frames 2. Then, the electric telescopic rod 5 drives the hoisting moving plate 6 to move downwards, and the hook lock body 8 hooks the floor slab, suspending it in the air. The electric slide rail 3 drives the main top plate 4 to move, which in turn moves the hook lock body 8, transporting the floor slab to the designated location. When the floor slab is suspended for transport, it may fall during the process. Therefore, this needs to be improved to catch the floor slab in case of a fall. First, a suitable support frame 10 is selected, and then moved below the connecting rod 9. The mounting screw 12 is fixed into the mounting screw groove 13, and the support frame 10 is installed below the connecting rod 9. The connecting rod 9 moves with the hoisting moving plate 6, and the support frame 10 moves with the connecting rod 9, so that no matter where the floor slab moves, the support frame 10 is always below the floor slab to catch it. The support frame 10 is equipped with... The rubber padding layer 19 is used to protect the inside of the receiving groove 14. When the rubber padding layer 19 needs to be replaced, rotate the assembly nut 17 to move it out of the outside of the assembly screw 16, and then pull the base plate 15 to move the assembly screw 16 out of the assembly through groove 18. The base plate 15 is then moved out of the receiving groove 14, and the rubber padding layer 19 can be removed from the receiving groove 14 for replacement. When using the lifting device, common tools such as wrenches and screwdrivers are often needed. Therefore, the receiving frame 10 has a built-in tool storage function. First, pull the magnetic plate 26 to move it out of the outside of the toolbox 20. The toolbox 20 is made of corrosion-resistant iron material. Then, continue to pull to move the tool frame 23 outside the slide bar 21 via the slider 22 and remove it from the toolbox 20 via the retrieval slot 25. At this time, the tools in the tool slot 24 can be taken out for use. After use, they can be put back in their original place for storage, which is convenient and quick.
