By setting the connecting cloth 1, after the prone platform is installed and fixed on the power tower, workers can lie down or stand on the connecting cloth 1 to perform maintenance work, and portable tools can also be placed on the surface of the connecting cloth 1, thereby facilitating workers to perform maintenance work and reducing the risk of high-altitude operations.

[0026] The four groups of tower hanging units are respectively arranged at the ends of the four folding rods 21 , and the tower hanging units include a rotating shaft 31 , a fixing part, an adjusting arm 35 and a clamp for connecting the iron tower.

[0027] A bearing is mounted on one end of the rotating shaft 31, and the bearing is installed on the folding rod 21 so that the rotating shaft 31 can rotate. Two through holes are provided on the rotating shaft 31, and the two through holes are arranged in a cross shape. The fixing part includes a positioning screw 33 and a fixing nut 34 welded on the folding rod 21. The positioning screw 33 passes through the through hole and is threadedly connected with the fixing nut 34 to fix the rotating shaft 31 so that the rotating shaft 31 does not rotate.

[0028] A fixing sleeve 32 is welded to the other end of the rotating shaft 31, and the adjusting arm 35 is arranged in the fixing sleeve 32. The clamp includes a T-shaped seat 42 and a clamping plate 43. A connecting nut 41 is fixedly connected to one end of the T-shaped seat 42 close to the adjusting arm 35.

[0029] When used specifically, the present invention is a prone platform for high-altitude operations on power towers. First, the worker carries the prone platform to the maintenance position of the power tower, then fully unfolds the four folding rods 21, and uses bolts 23 to connect the left and right connecting sleeves 22. Then, the connecting rod 51 is rotated and threadedly connected to the rear folding rod 21 through a locking screw 52, ​​so that the front and rear folding rods 21 are connected and fixed. After the folding support frame is unfolded and fixed, the two clamps on the left are connected to the tower body of the power tower. After that, the positions of the adjustment arm 35 and the clamps on the right are adjusted, and the two clamps on the right are connected to the upper or lower tower cross arm, and the lying platform is installed and fixed on the power tower (such as Figure 4 shown); Finally, the worker can lie prone or stand on the connecting cloth 1 to perform maintenance work, and portable tools can also be placed on the surface of the connecting cloth 1.

[0030] Embodiment 2: On the basis of the first embodiment, Figure 2 As shown, it also includes an X-shaped rod 61, the four ends of the X-shaped rod 61 are respectively in contact with the bottoms of the four folding rods 21, and the four ends of the X-shaped rod 61 are respectively threadedly connected to the four folding rods 21 through four locking screws 62. By setting the X-shaped rod 61, the front and rear groups of folding rods 21 can be connected to ensure the structural stability of the folding carrier.

[0031] Embodiment three: On the basis of the first embodiment, Figure 1 and Figure 2 As shown, a plurality of thread grooves 37 are sequentially provided on the adjusting arm 35, and a threaded hole is provided at a position corresponding to the thread groove 37 of the fixing sleeve 32, and the threaded hole and the corresponding thread groove 37 are threadedly connected with the same fixing screw 36 to fix the adjusting arm 35 so that the adjusting arm 35 will not slip, thereby ensuring the stability of the adjusting arm 35 during use.

[0032] When the clamp cannot be connected to the power tower, the fixing screw 36 is rotated in reverse to separate the fixing screw 36 from the thread groove 37, and then the sliding adjustment arm 35 is used to adjust the position of the clamp so that the clamp can be connected to the power tower.

[0033] Embodiment 4: On the basis of the first embodiment, Figure 3 As shown, the interior of the adjusting arm 35 is hollow, and one end thereof close to the connecting nut 41 is open. A nylon rope 7 is arranged inside the adjusting arm 35, and the two ends of the nylon rope 7 are respectively connected to the inner side surface of the adjusting arm 35 and the T-shaped seat 42.
