Optionally, the manned hanging basket is integrally U-shaped, the opening direction of the U-shaped manned hanging basket faces the tower body, and the left and right manned hanging baskets are arranged oppositely.
Optionally, the left and right manned hanging baskets are connected into a whole through the connecting device.
Optionally, the connecting device is a rail-type sliding frame.
Optionally, a plurality of groups of flexible wheels, a plurality of first turnover net plates and a plurality of inflatable bags are arranged on one side of the manned hanging basket, which is in contact with the tower body, and a second turnover net plate is arranged on the outer side of the manned hanging basket.
Compared with the prior art, the invention has the advantages that:
1. the invention can meet the use requirements of different tower types and has strong universality;
2. the invention can overcome the swing problem caused by the influence of wind force in the super high altitude operation, and improve the operation stability;
3. the invention adopts multiple safety measures (turning over the baffle and filling the air bag), and can ensure the safety of equipment and personnel in the construction process;
4. the left manned hanging basket and the right manned hanging basket are symmetrically arranged, and are lifted simultaneously through the plurality of lifting motors, so that the balance of the manned hanging baskets is effectively ensured;
5. the left and right manned hanging baskets can be assembled into a whole, the whole platform surrounds the tower body, the whole platform cannot swing randomly under wind power and the like, and the stability is good;
6. the two manned hanging baskets are connected by adopting the rail type sliding frame, the requirements of construction at different heights and different positions of the A-shaped cable tower can be met, the anchoring intervals of different stay cables can be adapted, and the spanning of the stay cables can be realized by opening and closing.
