To address this, a new safety net for foundation pit protection can be designed. This new net uses a grounding plate to position the column body and a first installation block to install the net installation structure. A threaded rod, in conjunction with the first positioning platform and the column body, drives a moving platform, which in turn moves the anchor bolts to insert into the ground or remove them, thus improving the fixation effect of the column body.

The threaded rod 8, in conjunction with the first positioning platform 4 and the column body 1, drives the moving platform 6 to move, so that the moving platform 6 drives the anchor bolt 7 to rise and fall, so as to insert into the ground or pull out, thereby improving the fixing effect of the column body 1.

[0024] Please see Figures 2-4In this embodiment, a rotating block 9 is fixedly connected to the upper end of the threaded rod 8. A limiting block 10 is rotatably connected to the outer side of the rotating block 9. The limiting block 10 is slidably connected to the column body 1. A docking platform 11 is fixedly connected to the upper end of the rotating block 9. The rotating block 9 and the threaded rod 8 are rotated through the docking platform 11, thereby driving the moving platform 6 to rise and fall. A rotating rod 12 is provided at the upper end of the docking platform 11. A connecting block 13 is fixedly connected to the lower end of the rotating rod 12. A fixing block 14 is fixedly connected to the upper end of the rotating rod 12. The connecting block 13 is slidably connected to the docking platform 11. The rotating rod 12 is rotated through the fixing block 14, so that the docking platform 11 can be rotated through the connecting block 13. An installation frame 15 is provided on the inner side of the first mounting block 3. A second positioning platform 16 is fixedly connected to the inner side of the installation frame 15. The front and rear ends of the installation frame 15 are slidably connected to the sliding grooves 17. The installation frame 15 is used to expand the installation position of the protective structure to adapt to the shape of the foundation pit and improve the flexibility of the protective net installation.

[0025] Please see Figures 4-5 In this embodiment, a slider 18 is provided at the lower end of the second positioning platform 16, and a locking block 19 is installed at the upper end of the slider 18. The slider 18 and the mounting frame 15 are slidably connected through a sliding groove 17. A spring 20 is installed between the locking block 19 and the second positioning platform 16. The slider 18 can be moved through the mounting frame 15 and the sliding groove 17 to cooperate with the spring 20 to drive the locking block 19 to move, so as to connect to the first mounting block 3 to fix the mounting frame 15. An extension frame 21 is installed on one side of the mounting frame 15. An installation groove 22 is opened on one side of the extension frame 21. The upper and lower ends of the extension frame 21 are fixedly connected to the second mounting block 3. The second mounting block 23 is equipped with a protective netting through the extension frame 21 and the mounting groove 22 to surround the foundation pit. A fixing plate 24 is provided on the outer side of the second mounting block 23. A protective pad 25 is installed on one end of the fixing plate 24. The protective pad 25 is slidably connected to the first mounting block 3. A protective netting body 26 is provided between the two extension frames 21. Mounting strips 27 are fixed to both ends of the protective netting body 26. The mounting strips 27 are slidably connected to the extension frame 21 through the mounting groove 22. The fixing plate 24 is installed through the second mounting block 23 to protect the locking block 19 and to fix the protective netting body 26 in conjunction with the fixing mounting groove 22 and the mounting strips 27.

[0026] During installation, firstly, the positioning column body 1 is installed through the grounding plate 2, and the column cover plate 5 is removed to insert the rotating rod 12. Next, the connecting block 13 is connected to the docking platform 11, and the rotating rod 12 is rotated through the fixing block 14 so that the docking platform 11 can be rotated through the connecting block 13. Then, the rotating block 9 and the threaded rod 8 are rotated through the docking platform 11 to cooperate with the first positioning platform 4 and the column body 1 to drive the moving platform 6 to rise and fall. Finally, the anchor bolt 7 is raised and lowered through the moving platform 6 to be inserted into the ground to improve the fixing effect of the column body 1.

[0027] When installing the protective net, firstly, the mounting bracket 15 is placed on the first mounting block 3. Then, the slider 18 and the locking block 19 are moved by the sliding groove 17, and the locking block 19 is engaged with the first mounting block 3 by the spring 20 to fix the mounting bracket 15. Then, the protective net body 26 is installed by the extension bracket 21, the mounting groove 22 and the mounting strip 27 to surround the foundation pit. Finally, the fixing plate 24 is installed by the second mounting block 23 to protect the locking block 19 and position and fix the mounting strip 27 to improve the fixing effect of the protective net body 26.

[0028] Through the above steps, the positioning column body 1 is installed using the grounding plate 2, and the protective net installation structure is installed using the first installation block 3. The threaded rod 8, in conjunction with the first positioning platform 4 and the column body 1, drives the moving platform 6 to move, thereby driving the anchor bolts 7 to rise and fall, inserting or pulling them out of the ground. This improves the fixing effect of the column body 1 and solves the problem that most existing foundation pit protection safety nets are equipped with fixed column installation structures and anchor structures. During use, the anchor structure is inserted into the ground, and the column is fixed using the installation structure. However, the fixed anchor structure is easily damaged during handling, insertion, extraction, and use, affecting the overall use effect of the column and leading to a decrease in the efficiency and an increase in the cost of using the foundation pit protection safety net.
