The ladder cage unit is formed by vertically stacking and installing a plurality of ladder cage units along the vertical shaft direction. The ladder cage unit includes a main frame that matches the size of the internal space of the shaft. The upper and lower openings of the main frame form an upper inlet and a lower inlet, and a channel is formed in the middle of the main frame. A protective net is installed around the main frame. A ladder that connects the upper and lower inlets is installed in the channel of the main frame. A threaded hole group is provided on each outer side surface of the top crossbeam of the main frame and each outer side surface of the bottom crossbeam. The threaded hole group is equipped with short rods and long rods for connecting the main frames. The threaded hole group includes a plurality of threaded holes arranged horizontally and evenly spaced. Screws corresponding to the threaded holes are installed on the short rods and the long rods. The short rods and the long rods can be installed in the threaded holes of the main frame by screws. After the ladder cage units are stacked, adjacent main frames are connected by short rods, and multiple main frames are connected by long rods.

[0005] In this embodiment, the ladder includes a left-turn step, a right-turn step, an upper ladder and a lower ladder.

The upper ladder and the lower ladder connect the upper and lower left-turn steps with the right-turn step respectively, so that the ladder forms a Z-shaped ladder structure.

[0006] In this embodiment, a positioning column is fixed to each of the four corners of the top surface formed by the top crossbeam of the main frame, and four positioning holes matching the positioning columns are opened on the bottom surface formed by the bottom crossbeam of the main frame.

[0022] like Figure 1-5 The ladder 1 is a vertical folding structure that is convenient for construction and is composed of a plurality of ladder cage units vertically stacked and installed in the direction of the ladder. The ladder cage unit includes a main frame 1 that matches the size of the internal space of the ladder. The main frame 1 is a rectangular frame fixed by crossbeams and support columns. The upper and lower openings of the main frame 1 form upper and lower entrances and exits. A protective net 2 is installed around the main frame 1. A ladder connecting the upper and lower entrances is provided in the main frame 1. Further, in this embodiment, the ladder includes a left-turning platform 3, a right-turning platform 4, an upper ladder 5 and a lower ladder 6. The two left-turning platforms 3 are arranged on the same side of the main frame 1 and are respectively fixed on the crossbeams in the upper and lower entrances and exits. The right-turning platform 4 is fixed in the main frame 1, on the side opposite to the left-turning platform 3 and is placed between the two left-turning platforms 3. The upper ladder 5 and the lower ladder 6 connect the upper and lower left-turning platforms 3 with the right-turning platform 4, respectively, so that the ladder forms a Z-shaped ladder structure.

[0023] A positioning column 7 is fixed to each of the four corners of the top surface formed by the top crossbeam of the main frame 1, and four positioning holes 8 matching the positioning columns 7 are opened on the bottom surface formed by the bottom crossbeam of the main frame 1;

[0024] A threaded hole group is provided on each outer side surface of the top cross beam of the main frame 1 and each outer side surface of the bottom cross beam. The threaded hole group is equipped with a short rod 23 and a long rod 10 for connecting the main frame 1. The threaded hole group includes a plurality of threaded holes 9 arranged horizontally and evenly spaced. Screws 11 corresponding to the threaded holes 9 are installed on the short rod 23 and the long rod 10. The short rod 23 and the long rod 10 can be installed in the threaded holes 9 of the main frame 1 through the screws 11. After the cage units are stacked, adjacent main frames 1 are connected by short rods 23, and multiple main frames 1 are connected by long rods 10.

[0025] When the present invention is in use, multiple ladder cage units are stacked and placed so that the positioning columns 7 of the main frame 1 on the lower side are inserted into the inner sides of the positioning holes 8 on the lower side of the main frame 1 on the upper side. The adjacent main frames 1 are connected with the ladders arranged therein so that construction workers can walk safely in the main frames 1. Every time a layer of the main frame 1 is installed, the adjacent main frames 1 are connected by the short rod 23. Every time three or four layers of the main frame 1 are installed, the entire main frame 1 is fixedly connected by the long rod 10 at the same time. When the short rod 23 and the long rod 10 are connected to the main frame 1, they are threadedly connected to the threaded holes 9 of the main frame 1 through the screws 11 on the short rod 23 and the long rod 10. This device improves the flexibility of the shaft passage ladder cage through modular design. At the same time, the connection strength between the ladder cage units can be improved through the short rod 23 and the long rod 10. The short rod 23 can not only cooperate with the long rod 10 to structurally strengthen the entire middle part of the ladder cage, thereby enhancing the overall structural strength of the ladder cage, but also enables the ladder cage to be superimposed and fixed with a single main frame 1 in the vertical and horizontal directions, thereby improving the flexibility of the ladder cage and the applicability of the equipment to adapt to different construction environments, reducing the amount of bolt disassembly and assembly during construction, ensuring the safety of the ladder cage while having the characteristics of rapid installation and disassembly, reducing the labor intensity of construction, and reducing the waste of materials and time during the construction process, thereby improving the efficiency of shaft construction.

[0026] like Figure 3 As shown, further, reinforcement blocks 12 are fixed on the top of the main frame 1 and the relatively arranged cross beams, a horizontally arranged cross bar 13 is installed between the two reinforcement blocks 12, and a lifting lug 14 is installed in the middle of the cross bar 13. When the lifting lug 14 is arranged, it is best to be on the center of gravity of the entire ladder cage unit to ensure the stability of the lifting of the entire ladder cage unit; and the position of the cross bar 13 does not interfere with the ladder, so as to prevent it from affecting the walking of subsequent construction workers and improve the convenience of using the equipment.

[0027] like Figure 4As shown, the top of the positioning post 7 is tapered to form a tapered guide block 15, and the bottom of the corresponding positioning hole 8 is provided with an inclined chamfer 16 that matches the tapered guide block 15. The design of the tapered guide block 15 and the positioning hole 8 facilitates quick and accurate docking between modules, improving installation efficiency.

[0028] like Figure 5 As shown, two auxiliary support assemblies symmetrically distributed on the left and right are installed on the rear side of the main frame 1. The auxiliary support assembly includes a vertical plate 17 fixed to the outside of the support column of the main frame 1, and a sleeve 18 is fixed on the upper side of the vertical plate 17. A screw rod 19 is threadedly connected to the inner side of the sleeve 18. The screw rod 19 is rotated on the side facing the inner wall of the shaft and is equipped with a fixing plate 21. A handle 20 for facilitating the rotation of the screw rod 19 is installed on the other side of the screw rod 19. A plurality of through holes are installed on the upper side of the fixing plate 21 to form a fixing hole 22.

[0029] The length of the rear side of the screw rod 19 can be adjusted by turning the handle 20. At the same time, the fixing plate 21 can be fixed to the side of the shaft through the fixing hole 22 by using expansion screws or the like. The auxiliary support assembly can provide an additional fixing method for the ladder cage, especially in non-standard construction environments, to ensure the stability and safety of the ladder cage.
