[0002] Electric energy plays an increasingly important role in the national economy. Doing a good job in power maintenance is conducive to improving the reliability of power supply, reducing maintenance costs, and improving economic benefits. The use of condition-based maintenance methods can reduce the number of power outages in substations and shorten the power outage time.

[0022] The embodiments of the present invention will be further described below with reference to the attached drawings.
[0023] Embodiment:
[0024] As Figures 1 - 4 shown, a folding ladder for power maintenance includes a first ladder 1 and a second ladder 3. A connector 2 is fixedly connected between the tops of the first ladder 1 and the second ladder 3. A connecting folding reinforcement rod 4 is arranged between the outer sides of the surfaces of the first ladder 1 and the second ladder 3. A second reinforcement mechanism 6 is arranged at the bottom of the outer side of the surface of the first ladder 1, and a first reinforcement mechanism 5 is arranged at the bottom of the outer side of the surface of the second ladder 3.
[0025] The working principle of the above technical solution is as follows:
[0026] During the use process, when the first ladder 1 and the second ladder 3 are deflected and unfolded at the bottom of the connector 2, the connecting folding reinforcement rod 4 can be folded and unfolded. Then, the first reinforcement mechanism 5 and the second reinforcement mechanism 6 are deflected and adjusted so that the ends of the first reinforcement mechanism 5 and the second reinforcement mechanism 6 are engaged with each other, thereby being able to reinforce between the bottoms of the first ladder 1 and the second ladder 3, improving the overall use stability and safety, and being convenient to operate.
[0027] In another embodiment, as Figure 3 shown, the first reinforcement mechanism 5 includes a first T-shaped positioning rod 7. A fixed limit disk 8 is fixedly sleeved on the outer side of the surface of the first T-shaped positioning rod 7. A first deflection arm 9 is movably sleeved on the outer side of the surface of the first T-shaped positioning rod 7. A connecting clamping block 10 is fixedly connected to the top of the first deflection arm 9, and a fixed positioning hole 11 is opened on one side of the connecting clamping block 10.
[0028] It is convenient to deflect the first deflection arm 9 on the outer side of the surface of the first T-shaped positioning rod 7, so that the connecting clamping block 10 can move, and the connecting clamping block 10 can be inserted into the inner side of the end of the second reinforcement mechanism 6, thereby being connected and clamped with the second reinforcement mechanism 6, and being convenient to operate.
[0029] In another embodiment, as Figure 3 shown, the second reinforcement mechanism 6 includes a second T-shaped rod 12. A second deflection arm 13 is movably sleeved on the outer side of the surface of the second T-shaped rod 12. A fixed card slot 14 is formed at the top of the second deflection arm 13. A connection limiting and reinforcing mechanism 16 is fixedly connected to one side at the top of the fixed card slot 14. The inner side of the fixed card slot 14 has a certain arc.
[0030] It is convenient to deflect the second deflection arm 13 on the outer side of the surface of the second T-shaped rod 12, so that the connection block 10 can be inserted into the inner side of the fixed card slot 14 for connection and fixation. At the same time, the fixed card slot 14 having a certain arc can facilitate the connection block 10 to be snapped into the inner side of the fixed card slot 14 for connection.
[0031] In another embodiment, as Figure 3 shown, a guiding inclined surface 15 is provided on one side of the fixed card slot 14.
[0032] The guiding inclined surface 15 can guide the connection block 10, facilitating the connection block 10 to be inserted into the inner side of the fixed card slot 14, so as to perform connection and fixation, which is convenient to use.
[0033] In another embodiment, as Figure 3 shown, the cross-sectional shape of the connection block 10 is T-shaped, and the outer side of the surface of the connection block 10 fits with the inner side of the fixed card slot 14.
[0034] It is convenient for the connection between the connection block 10 and the fixed card slot 14 to be stable, and the operation is convenient.
[0035] In another embodiment, as Figure 4 shown, the connection limiting and reinforcing mechanism 16 includes an installation frame 17. An active limiting insertion rod 18 is movably connected inside the installation frame 17. One end of the active limiting insertion rod 18 is fixedly connected to a connection pulling plate 21. A fixed stress ring 19 is fixedly sleeved on the outer side of the surface of the active limiting insertion rod 18. A stress spring 20 is fixedly connected between one side of the fixed stress ring 19 and the inner side of the installation frame 17.
[0036] It is convenient to pull the connection pulling plate 21 to drive the active limiting insertion rod 18 and the fixed stress ring 19 to move, compress the stress spring 20, and thus perform rapid adjustment.
[0037] In another embodiment, as Figure 4 shown, fixed guiding rods 22 are symmetrically arranged on the inner side of the installation frame 17. The other ends of the fixed guiding rods 22 are slidably and fittingly connected with the inside of the fixed stress ring 19.
[0038] The facilitating fixing guide rod 22 can guide and restrict the fixing force-bearing ring 19, enabling the movable limit insertion rod 18 to move stably, which is convenient to operate.
[0039] The working principle of the present utility model: During use, first unfold between the first ladder frame 1 and the second ladder frame 3, so that the connecting folding reinforcement rod 4 is fully extended. Then, first drive the connecting limit reinforcement mechanism 16 as a whole to deflect by the second deflecting arm 13, then deflect the first deflecting arm 9 to drive the connecting block 10 to move. Then pull the connecting pull plate 21 to drive the movable limit insertion rod 18 and the fixing force-bearing ring 19 to move, compressing the force-bearing spring 20, so that the end of the movable limit insertion rod 18 can contract into the inside of the second deflecting arm 13. When the connecting block 10 can be stuck into the inside of the fixing card slot 14 under the action of the guiding inclined surface 15, release the connecting pull plate 21. Under the action of the force-bearing spring 20 on the fixing force-bearing ring 19, it can drive the movable limit insertion rod 18 to move, and the fixing force-bearing ring 19 can move on the outer surface of the fixing guide rod 22. At this time, the end of the movable limit insertion rod 18 can be inserted into the inside of the fixing positioning hole 11, so as to be connected and fixed, improving the overall connection stability and safety, and the operation is convenient and fast.
[0040] The above embodiments only represent the specific implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
