[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figures 1 to 5 , the invention provides a technical solution:

[0028] A manned lifting operation platform for a substation includes a walking system and a bottom plate 1 arranged on the walking system, a vertical lifting structure and a lifting structure 8 are arranged on the top of the bottom plate 1, a lateral translation structure is installed on the vertical lifting structure, and a manned operation structure is arranged at the lower end of the lateral translation structure; the manned operation structure includes a manned frame 2, the manned frame 2 includes an outer frame 21 and an inner frame 22, the inner frame 22 is arranged inside the outer frame 21, four groups of fixed plates 23 are fixedly arranged on the outer wall of the outer frame 21, and the lateral translation structure is connected to the four groups of fixed plates 23 through a first connecting rope; the lateral translation structure is also connected to the top of the inner frame 22 through a second connecting rope;

[0029] Specifically, the manned frame 2 is provided with an outer frame 21 and an inner frame 22 to ensure the safety of the operators. When the operators are on the manned frame 2, the first connecting rope provides tension to lift the entire manned frame 2. At this time, there is no tension between the second connecting rope and the inner frame 22. When the operator is used for a long time or is worn, in the prior art, when the rope breaks, it will cause the frame to tilt to one side, which will bring the risk of the operators falling. However, in the present technology, when the first connecting rope breaks, the outer frame 21 and the inner frame 22 are separated, and the outer frame 21 tilts to one side. At this time, the inner frame 22 and the second connecting rope generate tension, and the inner frame 22 is pulled by the second connecting rope, and the inner frame 22 continues to remain stable, which can ensure the stability of the operators and reduce greater risks. At the same time, compared with the fixing method using more ropes, this method will not block the working line of sight due to the existence of more ropes.

[0030] The vertical lifting structure includes a lifting frame base 3, a scissor-type lifting device 31 is arranged on the lifting frame base 3, a support plate 32 is arranged on the top of the scissor-type lifting device 31, and a lateral translation structure is installed on the top of the support plate 32. Specifically, the scissor-type lifting device 31 adopts any existing structure that can provide a vertical lifting function;

[0031] The lateral translation structure includes a long plate 4 and a sliding box 5. The sliding box 5 is slidably sleeved with the long plate 4. A sliding groove 41 is opened on the top of the long plate 4. A first servo motor 51 is fixedly arranged on the side wall of the sliding box 5. A rotating rod 52 is rotatably connected inside the sliding box 5. One end of the rotating rod 52 passes through the side wall of the sliding box 5 and is fixedly connected to the output end of the first servo motor 51. A driving disk 53 is arranged on the rotating rod 52. The bottom of the driving disk 53 abuts against the top of the sliding groove 41. The outer ring surface of the driving disk 53 is provided with a plurality of gear teeth. The top of the groove 41 is provided with teeth meshing with the first gear teeth; the first servo motor 51 is used to rotate and drive the driving plate 53 to slide on the slide groove 41, thereby driving the sliding box 5 to slide on the long strip 4; it is worth mentioning that when the operator is on the manned frame 2, the length of the first connecting rope and the first connecting rope is shortened, that is, the distance between the first connecting rope and the lateral translation structure is shorter, which is used to avoid the shaking of the manned frame 2 during lateral movement. When work is needed, the length of the first connecting rope and the first connecting rope is changed to adjust;

[0032] If the vertical lifting structure is used for adjustment, since the adjustment range is difficult to control, only a wide range of height adjustment can be performed. Therefore, the lateral translation structure also includes a fine-adjustment structure arranged at the bottom of the sliding box 5, and the first connecting rope and the second connecting rope are both connected to the inside of the fine-adjustment structure; the working height of the operator is adjusted by the fine-adjustment structure;

[0033] The fine-tuning structure includes two driving boxes 6 fixedly arranged at the bottom of the sliding box 5, both side walls of the driving box 6 are rotatably provided with a first rope reel 61, a through hole is arranged at the center of the bottom of the driving box 6, a cross wheel is rotatably arranged in the through hole, the first connecting rope is wound around the first rope reel 61, and the first connecting rope passes through the cross wheel, the outer walls of both sides of the driving box 6 are provided with a second servo motor 63, the output end of the second servo motor 63 is provided with a rotating shaft 64, the rotating shaft 64 passes through the wall surface of the driving box 6 and is fixedly connected to the first rope reel 61; the part of the rotating shaft 64 located in the wall surface of the driving box 6 is provided with a driving gear 65, the driving gear 65 is transmission-connected with a toothed belt 66, the other end of the toothed belt 66 is transmission-connected with a driven gear 67, the center of the driven gear 67 is fixedly provided with a rotating connecting rod 68, the end of the rotating connecting rod 68 is provided with a first bevel gear 69, the upper and lower ends of the outer arc surface of the cross wheel are provided with second bevel gears 62, and the first bevel gear 69 is meshed with the second bevel gear 62;

[0034] The cross wheel includes a rotating ring 7, which is rotatably installed inside the through hole, and the second bevel gear 62 is arranged on the outer periphery of the rotating ring 7; the cross wheel also includes a center block 71, which is located at the center of the rotating ring 7, and the center block 71 and the inner arc surface of the rotating ring 7 are connected with four groups of evenly distributed support rods 72, the first connecting rope includes an A rope 81 and a B rope 82, the A rope 81 and the B rope 82 are respectively wound around the two first rope winding drums 61, and the other ends of the A rope 81 and the B rope 82 pass through the cross wheel respectively, and are rotated and wound by the cross wheel to form a twist shape; the ends of the A rope 81 and the B rope 82 are separated and fixedly connected to the fixing plates 23 at both ends of the outer frame 21 respectively; specifically, when the second servo motor 63 drives the two first rope winding drums 61 inside to rotate, the A rope 81 and the B rope 82 of the first connecting rope pass through the cross wheel respectively. At this time The rotation of the first rope drum 61 drives the A rope 81 and the B rope 82 to extend. At the same time, the driving gear 65 rotates, and then drives the driven gear 67 to rotate through the transmission action of the toothed belt 66, and the driven gear 67 drives the rotating connecting rod 68 and the first bevel gear 69 at the end of the rotating connecting rod 68 to rotate. The upper and lower ends of the outer arc surface of the cross wheel are provided with the second bevel gear 62. Specifically, the cross wheel is similar to the end surface of the two bevel gears. When the first bevel gear 69 is rotated, due to the meshing, it will drive the second bevel gear 62 to rotate, and then drive the cross wheel to rotate. The rotation of the cross wheel, due to the four groups of evenly distributed support rods 72 to divide the cross wheel into zones, and the A rope 81 and the B rope 82 are respectively lowered from different zones, and the rotation of the support rod 72 will cause the A rope 81 and the B rope 82 to be entangled to form a twist shape, thereby reinforcing the overall stability;

[0035] A second rope drum 9 is also provided at the middle of the top of the driving box 6, and a wire outlet hole 73 is opened in the middle of the center block 71.
