[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] Please refer to Figure 1 - Figure 5 A tower inner cat ladder anti-falling device for high-altitude detection of a communication tower, comprising a cat ladder body 1, a stepping plate 2 fixedly assembled on the inner wall of the cat ladder body 1, a limiting groove 3 formed on the top of the stepping plate 2, a friction block 9 arranged on the inner wall of the limiting groove 3, a threaded groove 8 formed on the outer wall of the cat ladder body 1, a bolt 4 threadedly connected with the inner wall of the threaded groove 8, a limiting block 5 fixedly assembled on the outer wall of the bolt 4, a clamping assembly 6 arranged on the inner wall of the limiting block 5, and a protective rope 7 fixedly assembled on the outer wall of the clamping assembly 6.
[0023] In the above structure, the stepping plate 2 is formed on the top, and the friction block 9 is fixedly assembled on the inner wall of the limiting groove 3. When the worker steps on the inner wall of the limiting groove 3, the friction block 9 arranged on the inner wall rubs against the sole of the worker's shoe, effectively preventing the worker from slipping during climbing, thereby achieving the anti-slip effect.
[0024] In a preferred embodiment, the clamping assembly 6 comprises a clamping block 601, a fixed block 602 fixedly assembled on the outer wall of the clamping block 601, a rotating rod 603 rotatably connected with the inner wall of the fixed block 602, a rotating plate 604 fixedly assembled on the outer wall of the rotating rod 603, an oblique square groove 606 formed on the outer wall of the clamping block 601, and a spring 605 fixedly assembled on the inner wall of the clamping block 601.
[0025] In the above structure, when the clamping operation of the clamping assembly 6 is performed, the worker needs to hold the clamping block 601 and guide the rotating plate 604 to press the outer wall of the limiting block 5. During this process, after the rotating plate 604 bears the pressure, it will further drive the rotating rod 603 to rotate around the axis of the inner wall of the fixed block 602. With the rotation of the rotating plate 604, the pressure is transmitted to the spring 605, which will produce corresponding expansion and contraction changes according to the force condition. At this stage, the elastic potential energy accumulated in the spring 605 is released, driving the spring 605 and the rotating plate 604 connected therewith to reset to the initial position without being pressed, thereby achieving the predetermined goal of anti-falling.
[0026] In a preferred embodiment, the oblique groove 606 is formed on the outer wall of the rotating plate 604 , and the spring 605 is fixedly assembled with the outer wall of the rotating plate 604 .
[0027] In the above structure, the outer walls of the clamping block 601 and the rotating plate 604 are both provided with oblique grooves 606 to limit the rotating plate 604 so that the rotating plate 604 will not rotate out of the inner wall of the clamping block 601 when rotating, and the rotating plate 604 is limited by the spring 605.
[0028] In a preferred embodiment, the clamping assembly 6 is clamped with the inner wall of the limiting block 5 , and the limiting block 5 and the clamping block 601 are both made of aluminum alloy.
[0029] In the above structure, the clamping assembly 6 is clamped with the inner wall of the limiting block 5 to limit the entire clamping assembly 6. The limiting block 5 and the clamping block 601 are made of aluminum alloy to achieve better part quality.
[0030] In a preferred embodiment, the friction block 9 is made of polyurethane, and the rotating plate 604 is rotatably connected to the inner wall of the fixed block 602 via the rotating rod 603 .
[0031] In the above structure, the friction block 9 is made of polyurethane to achieve greater friction when the staff steps on it, and the rotating plate 604 is limited by the rotating rod 603.
[0032] In a preferred embodiment, there are two groups of the clamping assemblies 6 , and the two groups of the clamping assemblies 6 are respectively located on the outer walls on both sides of the ladder body 1 .
[0033] In the above structure, two sets of clamping components 6 are used to limit the positions of the maintenance personnel on both sides, thereby preventing the maintenance personnel from deviating to one side.
[0034] Working principle: By stepping on the limit groove 3 opened on the top of the pedal 2, when the staff steps on the inner wall of the limit groove 3, the friction block 9 structure set on the inner wall of the limit groove 3 is intended to implement friction limiting measures on the soles of the staff's shoes, ensuring that the staff can stand stably during the climbing process, effectively preventing the occurrence of foot slippage, thereby achieving an anti-slip effect. When performing the clamping operation of the clamping assembly 6, the staff must first pick up the clamping block 601, and then the clamping block 601 will drive the rotating plate 604 component to apply pressure to the outer wall of the limit block 5. This pressure action prompts the rotating plate 604 to drive the rotating rod 603 to rotate on the inner wall of the fixed block 602. At the same time, the rotating plate 604 will apply pressure on the spring 605 during the rotation process, causing the spring 605 to undergo telescopic deformation. Subsequently, the elastic potential energy stored in the spring 605 is released, prompting the spring 605 to drive the rotating plate 604 to automatically return to its initial state without being pressed, thereby achieving an anti-fall function.
[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
