[0032] The second fixing component 5 is used to fix the docking frame 6 to the corresponding position on the power tower. The top of the docking frame 6 has a hole for inserting one end of the hook 8. The top, bottom and one side of the docking frame 303 are open to facilitate the insertion of the fixing frame 302. The docking frame 303 and the square ladder body 1 are connected to the mounting rod 2 by bolts. The fixing frame 302 is connected to the first fixing component 4. The first fixing component 4 is used to easily fix the fixing frame 302 to the corresponding position on the power tower.

[0033] The first fixing component 4 includes a first limiting frame 401, a fixing bolt 402, a washer 403, a second limiting frame 404, and a docking block 405. The docking block 405 is located at the top and bottom of the first limiting frame 401 and the second limiting frame 404, respectively. The fixing bolt 402 and the docking block 405 are threaded together to fix the first limiting frame 401 and the second limiting frame 404 to the power tower.

[0034] The 403 gasket is used to ensure stability at the connection between the extension frame and the power tower.

[0035] The square ladder body 1 has sliding components 10 installed on both sides of the front side, and the sliding components 10 have movable rings 11 fixedly connected to the front side.

[0036] The sliding assembly 10 is connected to the square ladder body 1 by bolts, which facilitates disassembly and assembly.

[0037] The sliding assembly 10 includes a fixed frame 101, a movable frame 102, and a slide bar 103, wherein the slide bar 103 is used to install the movable frame 102 inside the fixed frame 101;

[0038] The top and bottom of the slide bar 103 are connected to the top and bottom of the fixed frame 101. The back of the inner wall of the fixed frame 101 is provided to facilitate docking with the limit bolt 16 after compression, so as to lock the movable frame 102.

[0039] The movable frame 102 has a movable opening 14 on the front near the bottom, and a limit bolt 16 is slidably connected inside the movable opening 14.

[0040] After the movable block 13 is subjected to downward force and moves downward, it can squeeze one end of the limit bolt 16.

[0043] The working principle of the square ladder installation structure for power towers provided by this utility model is as follows:

[0044] The hooks 8 and the docking frame 6 are connected by interlocking. The use of limiting pads 7 increases the stability of the connection between the hooks 8 and the docking frame 6. After the hooks 8 and the docking frame 6 are connected, the square ladder body 1 is attracted to the power tower via the magnetic attraction component 3, ensuring stability and preventing the square ladder body 1 from shaking during use. In actual use, the docking frame 6 is first fixed to the corresponding position on the power tower using the second fixing component 5. Simultaneously, the docking plate 301 of the magnetic attraction component 3 is also fixed to the corresponding position on the power tower using the first fixing component 4. The docking bracket 303 of the magnetic attraction component 3 is installed on the corresponding position on the back of the square ladder body 1, allowing the docking bracket 303 and... The fixing bracket 302 is positioned accordingly. When connection is needed, simply insert the hook 8 from the top of the docking frame 6 and align the hook 8 with the limiting pad 7. During this process, the fixing bracket 302 with the second magnetic attraction component 306 will snap into the interior of the docking frame 303 and attract the first magnetic attraction component 305, thus fixing the square ladder body 1. When it is necessary to remove it, simply push the square ladder body 1 upward to separate the first magnetic attraction component 305 and the second magnetic attraction component 306, and at the same time let the hook 8 slide out from the top of the docking frame 6, so that the square ladder body 1 can be removed.
