Detailed Implementation

[0024] The following is combined Figures 1 to 6 This utility model will be described in detail.

[0025] An active cross bracing for a cable tower includes a cable tower 1, with walking channels 101 connected to both sides of the middle of the cable tower 1, and active cross bracing 2 provided on both sides of the middle of the cable tower 1. The active cross bracing 2 is connected to the top of a supporting steel frame 201, and a movable platform 3 is provided on the top of the supporting steel frame 201. A platform plate 301 is connected to the middle of the movable platform 3, and a fitting block 302 is provided on one side of the platform plate 301. A mating block 303 is provided on the side of the platform plate 301 away from the fitting block 302. The supporting steel frame 201 consists of several I-beams arranged in a row. The movable platform 3 is connected to the supporting steel frame 201 by several horizontal reinforcing bars at the bottom. Several platform plates 301 are spliced ​​onto the horizontal reinforcing bars at the bottom of the movable platform 3.

[0026] First, walkways 101 are built on both sides of the middle of the cable tower 1 to allow construction workers to move around on both sides of the middle of the cable tower 1. Then, active cross bracing 2 is built to stabilize the cable tower 1. At the same time, a supporting steel frame 201 is set on the cable tower 1 to support the mobile platform 3, so that it is not necessary to build a supporting structure at the bottom of the mobile platform 3.

[0027] Furthermore, the mating block 302 is a protrusion on the top side of one side of the platform plate 301, and the mating block 303 is a protrusion on the bottom side of one side of the platform plate 301. The lengths of the mating block 302 and the mating block 303 are the same as the width of the platform plate 301. The mating block 302 also includes a limiting connecting block 3021, which is located at the bottom of the mating block 302 and is an "L"-shaped protrusion. The mating block 303 also includes a mating groove 3031, a limiting connecting groove 3032, and a limiting ball 3033. 1. A limiting connecting groove 3032 is set on the top of the mating block 303, and a limiting ball 3033 is set on one side of the fitting groove 3031. The limiting ball 3033 is set on both sides of the middle part of the limiting connecting groove 3032. The mating block 303 mates with the limiting connecting groove 3032 and the limiting connecting block 3021. There is a height difference between the limiting connecting groove 3032 and the mating block 303. The limiting ball 3033 is a ball connected to both sides of the middle part of the limiting connecting groove 3032 by a spring, and the protruding part of the limiting ball 3033 is on the surface of both sides of the middle part of the limiting connecting groove 3032.

[0028] The activity space of activity platform 3 is formed by splicing platform panels 301 to create a convenient walking surface. When splicing platform panels 301, a limiting connecting block 3021 on one side of the splicing platform panel 301 will fit into a fitting groove 3031 on another splicing platform panel 301. Then, by pushing the platform panel 301, the limiting connecting block 3021 will move along the fitting groove 3031, partially fitting into the limiting connecting groove 3032. When the connection point of the fitting block 3021 is pushed against the top of the opening of the limiting connecting groove 3032, the limiting connecting block 3021 will fall down and fully fit into the limiting connecting groove 3032, allowing the two platform panels 301 to be connected in parallel. Simultaneously, the limiting connecting block 3021 will also abut against the surface where the limiting connecting groove 3032 and the fitting groove 3031 differ in height, thus ensuring the limiting connection... The connecting block 3021 is used for limiting. When the limiting connecting block 3021 falls and is fully engaged in the limiting connecting groove 3032, it will compress the limiting ball 3033 to retract. After the limiting connecting block 3021 falls, the limiting ball 3033 will pop out again due to the spring, which will abut and limit the top two sides of the limiting connecting block 3021, so that the platform plate 301 will not be easily lifted. This makes the splicing between the platform plates 301 more stable and convenient, and there is no need to weld the platform plates 301 together to maintain the overall stability. The limiting connection between the limiting connecting block 3021 and the limiting connecting groove 3032 also makes it easier to disassemble the platform plate 301. At the same time, the two outermost edges of the platform plate 301 are not provided with the fitting block 302 and the mating block 303 to fix them to the movable platform 3.

[0029] The following is a detailed implementation process of this utility model: First, walking passages 101 are built on both sides of the middle of the cable tower 1 to allow construction workers to move around on both sides of the middle of the cable tower 1. Then, auxiliary active cross bracing 2 is built to stabilize the cable tower 1. At the same time, a supporting steel frame 201 is set on the cable tower 1 to support the movable platform 3, so that it is not necessary to build a support structure at the bottom of the movable platform 3. The movement space of the movable platform 3 will be accessed through the platform plate 301. The platform 301 is spliced ​​together to form a road surface that allows for easy movement. During the splicing of platform 301, a limiting connecting block 3021 on one side of platform 301 engages with a fitting groove 3031 on another platform 301. Then, by pushing the platform 301, the limiting connecting block 3021 moves along the fitting groove 3031, partially engaging with the limiting connecting groove 3032. When the connecting point of the fitting block 302 is pushed against the top of the opening of the limiting connecting groove 3032, the limiting connecting block 3021 falls down. The entire assembly fits into the limiting connection slot 3032, allowing the two platform plates 301 to be connected in parallel. Simultaneously, the limiting connection block 3021 abuts against the surface where the limiting connection slot 3032 and the fitting slot 3031 differ in height, thus limiting the limiting connection block 3021. When the limiting connection block 3021 falls and fully fits into the limiting connection slot 3032, it compresses the limiting ball 3033, causing it to contract. After the limiting connection block 3021 falls, the limiting ball 3033 springs back out due to the spring, thus limiting the limiting connection block 3021. The top two sides of 1 are abutted to limit the platform plate 301, so that it will not easily lift up, making the splicing between platform plates 301 more stable and convenient. There is no need to weld the platform plates 301 together to maintain the overall stability. The limiting connection of the limiting connecting block 3021 and the limiting connecting groove 3032 also makes it easier to disassemble the platform plate 301. At the same time, the two outermost edges of the platform plate 301 are not provided with the fitting block 302 and the mating block 303 to fix it to the movable platform 3.
