[0014] 1. The device is equipped with a first protective net, a first sliding bolt, and a second sliding bolt. When the first protective net needs to be quickly disassembled, firstly, remove the connecting device at the lower end of the first protective net, then remove the first nuts connecting the upper and lower outer ends of the first and second sliding bolts respectively. Pinch the protrusions on the front side of the first and second sliding bolts and slide and squeeze them toward the middle of the first spring, so that the first and second sliding bolts are separated from the inside of the fixed connecting block. At this time, the first protective net can be moved forward and disassembled, which facilitates the quick disassembly of the integrated safety protection device for elevator shaft construction.

[0015] 2. The device is equipped with a first protective net, fixing bolts, and a second protective net. When double protection is required, the second protective net is inserted into the fixing bolt at the rear end of the first protective net. The second protective net is then securely installed on the fixing bolt using the second nut. This ensures that the second protective net continues to provide protection even if the first protective net is damaged, facilitating double protection for elevator shaft construction safety.

[0016] 3. A third sliding bolt and a fixed connecting rod are provided. To ensure the stability of the mounting bracket, the elevator shaft opening itself is installed with a second screw. The front side is inserted into the inside of the mounting bracket.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: an integrated safety protection device for construction of building elevator shafts, including an installation frame 1, a first protective net 2, a fixed connecting block 3, a first sliding bolt 4, a first nut 5, a first spring 6, a second sliding bolt 7, a fixed bolt 8, a second protective net 9, a second nut 10, a first screw 11, a third sliding bolt 12, a second spring 13, a fixed connecting rod 14, a support plate 15, and a second screw 16.

[0025] When it is necessary to quickly disassemble the safety protection devices during the construction of a building elevator shaft, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the first protective net 2 is fixed with fixing connecting blocks 3 on both the left and right sides, and the fixing connecting blocks 3 are provided with first sliding bolts 4 inside. The upper end of the first sliding bolt 4 is provided with a first nut 5, the lower end of the first sliding bolt 4 is provided with a first spring 6, and the lower end of the first spring 6 is provided with a second sliding bolt 7. The rear end of the first protective net 2 is fixed with fixing bolts 8 on both the upper and lower sides, and the rear end of the fixing bolts 8 is equipped with a second protective net 9 and a second nut 10. The second nut 10 is located behind the second protective net 9. When the first protective net 2 is providing protection, the rear end is connected to the second protective net through the fixing bolts 8 and the second nut 10. 9. This achieves the effect of double-layer protection. When the first protective net 2 is damaged and needs to be disassembled, the first nuts 5 on the outer sides of the upper and lower ends of the first sliding bolt 4 and the second sliding bolt 7 are removed. The front protrusions of the first sliding bolt 4 and the second sliding bolt 7 are pinched and slid towards the middle of the first spring 6, so that the first spring 6 is squeezed and contracted. The first sliding bolt 4 and the second sliding bolt 7 are disengaged from the inside of the fixed connecting block 3. At the same time, the lower connecting device of the first protective net 2 has already been disassembled. Therefore, the first protective net 2 can be pulled forward as a whole to disassemble, repair and replace it. This is the way to disassemble the protective device.

[0026] When using this integrated safety protection device for elevator shaft construction, such as Figure 1 , Figure 2 and Figure 4 As shown, the lower end of the second nut 10 is provided with a third sliding bolt 12 and a second spring 13, and the second spring 13 is located in the middle of the third sliding bolt 12. The rear end of the third sliding bolt 12 is connected to a fixed connecting rod 14, and the rear end of the fixed connecting rod 14 is fixed with a support plate 15. The rear end of the support plate 15 is equipped with a second screw 16. When the mounting bracket 1 is installed on the wall by the first screw 11, in order to avoid the displacement phenomenon before installation, the elevator shaft opening uses the second screw 16 to fix the position of the support plate 15, and inserts the lower rear side of the mounting bracket 1 into the fixed connecting rod 14. At this time, the third sliding bolt 12 is rotated to connect with the fixed connecting rod 14 to fix the position of the mounting bracket 1, thereby better installing the mounting bracket 1. This is the usage method of the integrated safety protection device for the construction of the building elevator shaft.
