The first clamping plate 3 and the second clamping plate 4 are stably fixed on the ladder crossbar through the locking member 6, and the stabilizing block 5 is arranged on the top of the first clamping plate 3 on the inner side of the ladder crossbar. The stabilizing block 5 increases the contact area between the operator and the ladder crossbar. When personnel perform maintenance on the signal machine, they can stand on the stabilizing block 5 to perform maintenance on the signal machine, improving the stability of personnel standing on the climbing frame and reducing potential safety hazards. When personnel disassemble the locking member 6, the first clamping plate 3 and the second clamping plate 4 can be disassembled. The structure is simple and the operation is convenient.
[0029] In a preferred solution of this embodiment, a plurality of first limiting blocks 31 and a plurality of second limiting blocks are arranged on the side of the first clamping plate 3 close to the ladder crossbar. A plurality of first through holes and a plurality of second through holes 41 are arranged on the second clamping plate 4. Each first limiting block 31 is used to be arranged above the ladder crossbar, and each second limiting block is used to be arranged below the ladder crossbar. One first limiting block 31 is correspondingly arranged with one first through hole, and one second limiting block is correspondingly arranged with one second through hole 41. Each first limiting block 31 respectively passes through the corresponding first through hole and is detachably fixedly connected to the locking member 6, and each second limiting block respectively passes through the corresponding second through hole 41 and is detachably fixedly connected to the locking member 6. The structure is simple and the installation is convenient.
[0030] In a preferred scheme of the present embodiment, the locking member 6 includes a first cross bar, a second cross bar and a connecting rod, the first cross bar and the second cross bar are arranged in parallel, and the first cross bar and the second cross bar are both vertically fixedly connected to the connecting rod, a first limiting hole 32 is arranged on the first limiting block 31, and a second limiting hole 32 is arranged on the second limiting block, and the first cross bar passes through each first limiting hole 32 in sequence while the second cross bar passes through each second limiting hole 32 in sequence to fix the first clamping plate 3 and the second clamping plate 4 on both sides of the ladder cross bar. The structure is simple and the installation is convenient. The first clamping plate 3 and the second clamping plate 4 can be installed by inserting the locking member 6 into the first limiting block 31 and multiple second limiting blocks.
[0031] In a preferred solution of this embodiment, the first clamping plate 3 is tilted so that the first clamping plate 3 installed on the ladder crossbar is in a horizontal state.
[0032] In a preferred solution of the present embodiment, the ladder stabilizing device that is easy to disassemble also includes an extension plate 7. A storage groove 51 is provided on the side of the first clamping plate 3 facing the ladder cross bar. The extension plate 7 is slidably connected to the storage groove 51. The extension plate 7 can be stored in the storage groove 51. The extension plate 7 can be slid and pulled from the storage groove 51 but cannot be separated from the storage groove 51. When in use, the person holds the two sides of the ladder body 1 with their hands to climb. During the climbing process, the extension plate 7 in the stabilizing block 5 is in a stored state to prevent the extended extension plate 7 from hindering the person's climbing. When the person has finished climbing, the extension plate 7 is pulled out, which can increase the contact area with the person's feet and further improve the stability of the person when standing.
[0033] In a preferred scheme of the present embodiment, limiting grooves 52 are provided on both sides of the storage groove 51, and multiple limiting sliders 72 are provided on both sides of the extension plate 7 close to the inner end of the storage groove 51, and each limiting slider 72 is correspondingly slidably connected in the limiting groove 52, and both ends of the limiting groove 52 are not connected to the two sides of the first clamping plate 3 to limit the limiting slider 72 from sliding out of the limiting groove 52. When in use, with the cooperation of the limiting groove 52 and the limiting slider 72, the extension plate 7 will not fall off from the storage groove 51 during the process of extending outward, thereby ensuring the stability of the extension plate 7 during the extension process.
[0034] In a preferred solution of this embodiment, a protrusion 71 is provided on the top of one side of the extension plate 7 extending out of the storage groove 51. When in use, after standing on the upper end of the stabilizing block 5, a person can kick the protrusion 71 with his heel and drive the extension plate 7 to extend, which is convenient for the person to operate and use.
[0035] In a preferred solution of this embodiment, an anti-slip layer 53 is provided on the top surface of the first clamping plate 3. During use, through the anti-slip layer 53, the friction between the stabilizing block 5 and the person's foot is increased, reducing the possibility of the person slipping when standing on the stabilizing block 5, and further improving the stability of the person when standing.

[0038] In summary, the specific working process of this solution is as follows: When the first clamping plate 3 and the second clamping plate 4 are clamped on both sides of the climbing frame cross bar 2, the first limiting block 31 and the second limiting block on the first clamping plate 3 will penetrate through the first through hole and the second through hole 41 on the second clamping plate 4, and the first limiting block 31 and the second limiting block will contact the upper and lower ends of the climbing frame cross bar 2. Subsequently, the locking member 6 is penetrated through the first limiting hole 32 on the first limiting block 31 and the first limiting hole 32 of the second limiting block, thereby ensuring the stability of the installation of the first clamping plate 3 and the second clamping plate 4 on the climbing frame cross bar 2. When a person repairs the signal machine, they can stand on the stabilizing block 5 on the second clamping plate 4 to repair the signal machine, improving the stability of the person standing on the climbing frame cross bar 2 and reducing potential safety hazards. When the person removes the locking member 6, the first clamping plate 3 and the second clamping plate 4 can be disassembled;
[0039] Among them, the person holds both sides of the climbing ladder main body 1 with their hands to climb. During the climbing process, the extension plate 7 in the stabilizing block 5 is in a retracted state to prevent the extended extension plate 7 from hindering the person's climbing. When the person finishes climbing, the extension plate 7 is pulled out, which can increase the contact area with the person's foot and further improve the stability of the person when standing.
[0040] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope.
