[0031] Example 1, as Figure 1-7 As shown, an elevator shaft protection platform includes a fixed frame 1 and several scaffolding boards 5. One side of the fixed frame 1 is symmetrically and detachably connected to a load-bearing frame 4. A limiting device 2 is arranged between the load-bearing frame 4 and the scaffolding board 5. A supporting device 3 is arranged between the fixed frame 1 and the load-bearing frame 4. The limiting device 2 includes a card block 25. One side of the load-bearing frame 4 is provided with several card slots 21. One side of the scaffolding board 5 is symmetrically provided with rectangular holes 22. One side of the rectangular hole 22 is provided with a rectangular groove 23. The inner walls of the rectangular hole 22 and the rectangular groove 23 are both slidably connected to one end of the card block 25. One side of the inner wall of the rectangular groove 23 is fixedly connected with a spring 24. One end of the spring 24 is fixedly connected to one side of the card block 25. One end of the card block 25 is inserted in the inner wall of the card slot 21. One side of the scaffolding board 5 is symmetrically provided with a splicing groove 29. One side of the scaffolding board 5 is symmetrically fixedly connected with a splicing block 210, which is inserted in the splicing groove 29. When installing a protective platform inside the elevator shaft to protect against falling objects, the existing protective platform is generally installed at the door of the elevator shaft through a fixing frame 1, and then one end of the load-bearing frame 4 is fixed to one end of the fixing frame 1, and the other end is fixed to the inner wall of the elevator shaft with the help of bolts 34. Finally, the two blocks 25 on the scaffolding board 5 are manually slid to one end in the rectangular hole 22 and the rectangular groove 23 to a certain distance, driving the spring 24 to be compressed, and then the scaffolding board 5 is flattened on the load-bearing frame 4 to a certain position, and the block 25 is released. Under the reset effect of the spring 24, the scaffolding board 5 is compressed. The downward movement will drive one end of the card block 25 to be inserted into the inner wall of the card slot 21, so that the flat scaffolding board 5 can be fixed on the load-bearing frame 4. When installing adjacent scaffolding boards 5, the same operation is performed to fix them on the load-bearing frame 4, but the two splicing blocks 210 on one side will be stuck in the splicing grooves 29 on the adjacent scaffolding boards 5, so that the two adjacent scaffolding boards 5 are limited. In this way, during the use of the scaffolding board 5, it is not easy for the scaffolding board 5 to shake or move on the load-bearing frame 4, avoiding the formation of gaps between several scaffolding boards 5, improving the protection effect, and preventing the occurrence of safety hazards.

[0032] Reference Figure 2-5 As shown, this embodiment discloses that a plurality of protrusions 26 are fixedly connected to both sides of one end of the card block 25, and the plurality of protrusions 26 are arranged at equal distances. By providing the protrusions 26, the contact friction force on both sides of one end of the card block 25 can be increased, so that when it is manually pressed and pushed, it is not easy to slip in the hand, and it is convenient to operate it. Both sides of the card block 25 are fixedly connected to the limiting blocks 27, and the inner walls of the rectangular hole 22 and the rectangular groove 23 are provided with limiting grooves 28 on both sides. The limiting blocks 27 are slidably connected to the limiting grooves 28. By providing the limiting blocks 27 and the limiting grooves 28, the card block 25 is not easy to shake up and down when sliding back and forth in the inner walls of the rectangular hole 22 and the rectangular groove 23, and the movement is more stable.

[0033] Reference Figure 2-5 As shown, this embodiment discloses a telescopic rod 211 fixedly connected to one side of the inner wall of the rectangular groove 23. One end of the telescopic rod 211 is fixedly connected to one side of the clamping block 25, and the outer surface of the telescopic rod 211 is sleeved and connected to the inner wall of the spring 24. The provision of the telescopic rod 211 can provide support for the inner wall of the spring 24, making it less susceptible to damage during use and extending its service life.

[0034] Reference Figure 6 and Figure 7 As shown, this embodiment discloses a support device 3 including a support rod 33 and a bolt 34. A groove block 31 is symmetrically fixedly connected to one side of the fixing frame 1. Threaded holes 32 are provided on both sides of the inner wall of the groove block 31. One end of the support rod 33 is inserted into the inner wall of the groove block 31. The load-bearing frame 4 is clamped in the inner wall of one end of the support rod 33. The threaded hole 32 and the inner wall of the support rod 33 are both threadedly connected to the outer surface of one end of the bolt 34. Before the load-bearing frame 4 is installed on the fixing frame 1 for use, the support rod 33 can be manually grasped and inserted into the inner wall of the groove block 31. The bolt 34 is then screwed into the threaded hole 32 and the inner wall of one end of the support rod 33 and tightened to fix one end of the support rod 33 on the fixing frame 1. Then, one end of the load-bearing frame 4 is installed on the fixing frame 1 so that its outer surface is clamped in the inner wall of one end of the support rod 33 to support and reinforce it, thereby improving the load-bearing capacity of the load-bearing rod and enhancing the protective effect.

[0035] Reference Figure 6 and Figure 7 As shown, this embodiment discloses that one end of the support rod 33 has a T-shaped cross-section, and the inner wall of the groove block 31 has a T-shaped cross-section. By setting the inner walls of the support rod 33 and the groove block 31 to be T-shaped, they are less likely to shake after being inserted and installed together, and are fixed more firmly, facilitating the subsequent installation of the bolt 34. A connecting rope 35 is fixedly connected to one side of the bolt 34, and one end of the connecting rope 35 is fixedly connected to one side of the groove block 31. By providing the connecting rope 35, the bolt 34 can be limited to one side of the groove block 31, making it less likely to be lost after the bolt 34 is screwed out of the threaded hole 32. A limiting plate 36 is symmetrically fixed to one side of the groove block 31. The two limiting plates 36 are fixed at an angle on both sides of the entrance of the groove block 31. By providing the limiting plates 36, the area of ​​the entrance of the groove block 31 can be increased, making it easier for one end of the support rod 33 to be quickly aligned and inserted.

[0036] Working principle: by setting the limit device 2, when installing a protective platform inside the elevator shaft to protect against falling objects from high altitude, the existing protective platform is generally installed at the door of the elevator shaft through the fixing frame 1, and then one end of the load-bearing frame 4 is fixed to one end of the fixing frame 1, and the other end is fixed to the inner wall of the elevator shaft with the help of bolts 34. Finally, the two blocks 25 and the limit block 27 on the scaffolding board 5 are manually slid to one end in the two rectangular holes 22, the rectangular groove 23 and the limit groove 28 to a certain distance, driving the spring 24 and the telescopic rod 211 to be compressed, and then the scaffolding board 5 is flattened on the load-bearing frame 4 to a certain position, and then loosened. When the card block 25 is opened, one end of the card block 25 will be driven to be inserted into the inner wall of the card slot 21 under the resetting action of the spring 24 and the telescopic rod 211, so that the flat scaffolding board 5 can be fixed on the load-bearing frame 4. When installing adjacent scaffolding boards 5, the same operation is performed to fix them on the load-bearing frame 4, but the two splicing blocks 210 on one side will be stuck in the splicing grooves 29 on the adjacent scaffolding boards 5, so that the two adjacent scaffolding boards 5 are limited. In this way, during the use of the scaffolding board 5, it is not easy for the scaffolding board 5 to shake or move on the load-bearing frame 4, avoiding the formation of gaps between several scaffolding boards 5, improving the protection effect, and preventing the occurrence of safety hazards.

[0037] Before installing the load-bearing frame 4 on the fixing frame 1 for use, you can manually hold the support rod 33 and insert one end of it into the inner wall of the groove block 31, and then screw the bolt 34 into the threaded hole 32 and the inner wall of one end of the support rod 33 and tighten it, fixing one end of the support rod 33 on the fixing frame 1, and then install one end of the load-bearing frame 4 on the fixing frame 1 so that its outer surface is stuck in the inner wall of one end of the support rod 33 to support and reinforce it, thereby improving the load-bearing capacity of the load-bearing rod and improving the protection effect.
