In order to cooperate with high-rise buildings, the promotion and use of elevators is becoming more and more common. At the same time, in order to ensure the safety of elevators, regular maintenance and repairs are required, and workers are required to enter the elevator shaft through ladders to perform operations. At present, most ladders on the market are welded as a whole, and replacement and disassembly are very troublesome. Moreover, this traditional ladder has a very small area for stepping during the climbing process, which makes the climbing process very strenuous. Moreover, when arriving at the maintenance site, it is difficult to carry out maintenance while supporting and stepping on one side. Once the workers are not careful, they will fall from a height. At the same time, most of these old-fashioned ladders have no protective measures, and there are serious safety hazards. Therefore, there is an urgent need for a safe ladder that is easy to disassemble and has protective functions. Utility Model Content

When the workers are working, the ladder main frame 1 and the maintenance platform 5 can be used to climb up and down and perform construction work. At the same time, the anti-fall component 3 and the protective cage 4 can be used to provide safety protection when the workers are working, ensuring the safety of the workers in construction. By using the connecting component 6, multiple sections of the ladder main frame 1 can be installed together, and when a certain section of the ladder is damaged and needs to be disassembled and installed, it can be disassembled and replaced in time without affecting the normal use of other ladders. At the same time, because it is spliced, it can be installed according to different lengths The ladder main frame 1 is adapted for installation in the elevator shaft, and includes a main support column 101, a reinforcement rod 102, a widened stepping plate 103, a first anti-skid steel plate 104, a hook 105, a fixing plate 106 and a protective handrail 107; the main support column 101 is installed at the upper and lower ends of the connecting assembly 6; multiple groups of reinforcement rods 102 are installed at the side ends of the main support column 101; the upper end surfaces of the multiple groups of reinforcement rods 102 are all installed with widened stepping plates 103; the upper end surfaces of the widened stepping plates 103 are all installed with the first anti-skid steel plate 104; the side ends of the main support column 101 are provided with hooks 105; A fixing plate 106 is installed at the side end of the support column 101; a protective handrail 107 is installed on the main support column 101. When workers are working, the main support column 101 is fixed to the wall by bolts using the fixing plate 106 to ensure stability. At the same time, the widened pedal 103 installed thereon is strengthened and fixed using the reinforcement rod 102 to ensure the safety and stability of the workers when stepping on it. The first anti-slip steel plate 104 can increase the friction of the workers stepping on it and reduce the probability of safety accidents.

[0025] See also Figure 3 In this example, the protective cage 4 includes a guard ring 401, a strip guard plate 402, a mounting block 403, a slot 404, a movable clamping rod 405 and a rotating shaft 406; multiple sets of mounting blocks 403 are installed on the outer side of the ladder main frame 1; the multiple sets of mounting blocks 403 are each provided with a slot 404; a rotating shaft 406 is installed inside the slot 404; an movable clamping rod 405 is installed on the rotating shaft 406; the side ends of the multiple sets of mounting blocks 403 are each provided with a guard ring 401; a plurality of guard rings 401 are arranged between the two sets of guard rings 401. There is a strip guard plate 402. When workers are working, they use the guard ring 401 and the strip guard plate 402 to ensure the safety of the workers and prevent them from falling directly from a high altitude when encountering an emergency. If it is necessary to disassemble and replace the guard cage, first tighten the nut above the active clamping rod 405, and then use the rotating shaft 406 to move the active clamping rod 405 to both sides along the slot 404. When the position of the active clamping rod 405 is horizontal and the slot 404 is horizontal, the guard ring 401 installed on it can be removed.

[0026] See also Figure 4In this example, the maintenance platform 5 includes a platform 501, a supporting inclined rod 502, a guardrail 503, a baffle 504, a fall arrester 505 and a second anti-slip steel plate 506; the platform 501 is installed at the side end of the main support column 101; the second anti-slip steel plate 506 is arranged on the platform 501; the supporting inclined rod 502 is installed at the lower end of the platform 501; the guardrail 503 is installed on the platform 501; the baffle 504 is installed at one end of the supporting inclined rod 502; the fall arrester 505 is arranged on the guardrail 503. When the workers are working, they can stand on the platform 501 to carry out construction work, and at the same time hook the fall arrester 505 fixed on the guardrail 503 to their own safety rope, which will be directly locked to prevent falling from a high altitude when falling. A supporting diagonal rod 502 is installed under the platform 501, which can further fix the platform 501 installed on the main support column 101. The connecting component 6 includes a connecting plate 601, a plug plate 602 and a slot 603; the main support column 101 has slots 603 at the upper and lower ends; a connecting plate 601 is provided at the socket of the slot 603; a plug plate 602 is provided on the connecting plate 601; the slot 603 and the connecting plate 601 are disassembled and installed by fixing bolts, and the connecting plate 601 and the plug plate 602 are aligned with the entrance of the slot 603, and then the fixing bolts are installed, so that the two sections of the ladder main frame 1 can be stably connected, and at the same time, they can be disassembled and installed according to the different lengths of the elevator shaft, which solves the problem that the old safety ladder is difficult to disassemble and install.

[0027] When working, the main support column 101 is fixed to the wall by bolts using the fixing plate 106 to ensure stability, and the widened pedal 103 installed thereon is strengthened and fixed by the reinforcement rod 102 to ensure the safety and stability of the workers when stepping on it. The first anti-slip steel plate 104 can increase the friction of the workers stepping on it and reduce the probability of safety accidents. The protective handrail 107 can facilitate the workers to move up and down when climbing. At the same time, the guard ring 401 and the strip guard plate 402 can be used to ensure the construction safety of the workers and prevent them from falling directly from a high altitude when encountering an emergency. If it is necessary to disassemble and replace the guard cage, first screw the nut above the active clamping rod 405, and then use the rotating shaft 406 to move the active clamping rod 405 to both sides along the slot 404. When the position of the active clamping rod 405 is horizontal and the slot 404 is horizontal, the guard ring 401 installed thereon can be removed, which solves the problem that the guard cage is difficult to disassemble and replace.

[0028] Then, during construction work, workers can fix their safety belts on the fixing bolts 303, and use the fixing grooves 302 to fix the fixing bolts 303 on the fixing clamps 301, ensuring stability while protecting the safety of the workers. At the same time, they can stand on the platform 501 to carry out construction work, and use the fall arrester 505 fixed on the guardrail 503 to hook their safety ropes, which will directly lock them to prevent falling from a high altitude when they fall, further ensuring the safety of the workers' lives and solving the problem that it is difficult for workers to stand on the ladder for maintenance.

[0029] Through the above steps, when in use, workers can use the ladder main frame 1 and the maintenance platform 5 to climb up and down and perform construction work. At the same time, the anti-fall component 3 and the protection cage 4 can be used to provide safety protection when the workers are performing construction work to ensure the workers' construction safety. Using the connecting component 6, multiple sections of the ladder main frame 1 can be installed together. At the same time, when a certain section of the ladder is damaged and needs to be disassembled and installed, it can be disassembled and replaced in time without affecting the normal use of other ladders. At the same time, because it is spliced, it can be adapted and installed according to elevator shafts of different lengths.
