[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment

[0018] Please refer to the following: Figure 1 and Figure 2 A ladder platform for facilitating standing on power towers includes: a power tower body 1, a standing platform 2 installed on the outer wall of the power tower body 1, a guardrail 21 installed on the standing platform 2, and a limiting structure 3 installed on the outer wall of the power tower body 1. The limiting structure 3 is used to help workers maintain their balance when standing. A sliding structure 4 is slidably mounted on the surface of the limiting structure 3, and a fixing device 5 is mounted on the surface of the sliding structure 4; Placement structure 6 is rotatably mounted on the fixing device 5 and is used to place maintenance tools; When workers climb from the main body 1 of the power tower to the standing platform 2, they can rest on the platform. At the same time, the guardrail 21 prevents workers from falling. Initially, the placement structure 6 is in a vertical state, and the fixing device 5 limits the placement structure 6. When maintenance is required, the placement structure 6 is rotated from the vertical state to the horizontal state. The fixing device 5 supports the placement structure 6, and the maintenance tools that need to be used are stored in the placement structure 6, reducing the extra burden on workers and reducing physical exertion. When the location to be maintained changes, the sliding structure 4 slides around the main body 1 of the power tower on the limiting structure 3. The sliding structure 4 moves the fixing device 5 and the tools in the placement structure 6 to the maintenance point, making it convenient for workers to access and use them at any time.

[0019] Please refer to the following: Figure 2 The limiting structure 3 includes a connecting plate 31, a handrail ring 32, and a sliding groove 321. Multiple connecting plates 31 are installed at equal intervals on the outer wall of the power tower body 1. The handrail ring 32 is fixedly installed on one end of the multiple connecting plates 31. The sliding groove 321 is provided on both the upper and lower sides of the handrail ring 32. When workers move on the standing platform 2, they can grab the handrail 32 for support. At the same time, when changing the maintenance position, the sliding structure 4 slides in the slide groove 321 and moves with the workers to the vicinity of the maintenance point.

[0020] Please refer to the following: Figure 3 , Figure 4 and Figure 5 The sliding structure 4 includes a sliding sleeve 41, a slider 42, and an opening 43. The sliding sleeve 41 is slidably mounted on the surface of the handrail ring 32. The slider 42 is fixedly mounted on the inner wall of the sliding sleeve 41, and the slider 42 is slidably mounted inside the sliding groove 321. The sliding sleeve 41 has an opening 43 on the side near the power tower body 1 that is adapted to the connecting plate 31. When it is necessary to move the placement structure 6, the sliding sleeve 41 drives the slider 42 to slide in the sliding groove 321 and move it to the vicinity of the maintenance point. The slider 42 and the sliding groove 321 cooperate to prevent the sliding sleeve 41 from rotating on the surface of the handrail ring 32. At the same time, when the sliding sleeve 41 passes through the connecting plate 31, the connecting plate 31 passes through the opening 43 to avoid the connecting plate 31 blocking the sliding sleeve 41.

[0021] Please refer to the following: Figure 3 , Figure 6 and Figure 7The fixing device 5 includes a first fixing ring 51, a connecting block 52, a limiting hole 53, a sliding rod 54, and an elastic element 55. The first fixing ring 51 is fixedly installed on the surface of the sliding sleeve 41. The connecting block 52 is fixedly installed on one side of the first fixing ring 51. The connecting block 52 has the limiting hole 53. Two sliding rods 54 are symmetrically slidably installed in the limiting hole 53. The elastic element 55 is installed between the two sliding rods 54. Before use, the placement structure 6 is in a vertical position. The elastic element 55 pushes the two sliding rods 54 outward to limit the placement structure 6. The elastic element 55 can be a spring or a leaf spring, etc., with elasticity. The end of the sliding rod 54 extending to the outside of the connecting block 52 is spherical. When it is necessary to place the tool, the placement structure 6 is rotated, and the placement structure 6 pushes the spherical end of the sliding rod 54, pushing the sliding rod 54 to slide towards each other in the limiting hole 53. The sliding rod 54 compresses the elastic element 55. When the placement structure 6 is rotated to a horizontal position, the connection with the elastic element is released. When the sliding rod 54 contacts, the elastic element 55 pushes the sliding rod 54 to extend outward to the limiting hole 53. The sliding rod 54 supports the placement structure 6 and prevents the placement structure 6 from rotating due to gravity. When the maintenance point is changed, the sliding sleeve 41 drives the first fixing ring 51 and the placement structure 6 to slide and move to the vicinity of the maintenance point. After the maintenance is completed, the worker presses the two sliding rods 54 and pushes them inward, while rotating the placement structure 6 downward to a vertical state. At this time, the sliding rods 54 are released, and after the sliding rods 54 return to their initial position, they limit the placement structure 6 again.

[0022] Please refer to the following: Figure 3 , Figure 4 and Figure 6 The placement structure 6 includes a connecting rod 61, an abutment groove 611, and a tool box 62. Two connecting rods 61 are symmetrically and rotatably installed on both sides of the connecting block 52. The tool box 62 is fixedly installed at one end of the two connecting rods 61. The abutment groove 611 is opened on one side of each of the two connecting rods 61, and the abutment groove 611 is in contact with one end of the slide rod 54. When in use, the worker holds the toolbox 62 and lifts it upwards, causing the connecting rod 61 to rotate on the connecting block 52. When the connecting rod 61 and the slide rod 54 come into contact, the abutment groove 611 contacts the spherical end of the slide rod 54, pushing the slide rod 54 to slide into the limiting hole 53. When the connecting rod 61 rotates to a horizontal state, the connecting rod 61 is released from the slide rod 54, and the slide rod 54 returns to its initial position, supporting the connecting rod 61 and preventing the toolbox 62 and the connecting rod 61 from sliding due to gravity, which would cause the tools placed inside to fall out.

[0023] Second Embodiment

[0024] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The ladder platform for easy standing of personnel on the power tower also includes a fall protection structure 7, which is fixedly installed on the sliding sleeve 41. The fall protection structure 7 is used to lock the personnel in place and provide fall protection. In this implementation, before maintenance work is carried out, the anti-fall structure 7 protects the worker and limits the worker's sliding radius to prevent him from falling away from the standing platform 2. At the same time, when the maintenance point changes, the sliding sleeve 41 can move synchronously with the anti-fall structure 7 and the placement structure 6 without interfering with the worker's maintenance.

[0025] Please refer to the following: Figure 3 and Figure 4 The fall protection structure 7 includes a second fixing ring 71 and a protective waist ring 72. The second fixing ring 71 is fixedly installed on the surface of the sliding sleeve 41, and the protective waist ring 72 is fixedly installed on the second fixing ring 71. After the worker climbs onto the standing platform 2, the protective waist ring 72 is put on to protect the worker. At the same time, the protective waist ring 72 drives the second fixing ring 71 and the sliding sleeve 41 to slide, ensuring that the worker can move around at any time during maintenance without affecting the maintenance work.

[0026] The working principle of the ladder platform for convenient standing on power towers provided by this utility model is as follows: When the worker climbs to the standing platform 2 and rests there, the connecting rod 61 and toolbox 62 are in a vertical position before maintenance. The elastic element 55 pushes the two sliding rods 54 outward to limit the connecting rod 61. During maintenance, the worker holds the toolbox 62 and lifts it upward, causing the connecting rod 61 to rotate on the connecting block 52. When the connecting rod 61 and the sliding rod 54 come into contact, the abutment groove 611 contacts the spherical end of the sliding rod 54, pushing the sliding rod 54 to slide into the limiting hole 53. When the connecting rod 61 rotates to a horizontal position, it disengages from the sliding rod 54, which returns to its initial position, supporting the connecting rod 61. The necessary maintenance tools are stored in the toolbox 62, reducing the extra burden on workers and minimizing physical exertion. When the location requiring maintenance changes, the sliding sleeve 41 drives the first fixing ring 51 and the toolbox 62 to slide around the power tower body 1 on the handrail ring 32, moving them to the vicinity of the maintenance point for easy access to tools. A protective waist ring 72 is installed. After the worker climbs onto the standing platform 2, they wear the protective waist ring 72 for protection. Simultaneously, the protective waist ring 72 drives the second fixing ring 71 and the sliding sleeve 41 to slide, ensuring the worker can move freely during maintenance without affecting the work.
