[0036] For example, in the embodiment, the transverse bearing ropes 301 and the longitudinal bearing ropes 302 are all steel wire ropes, the two ends of the longitudinal bearing rope 302 are respectively anchored on the fixed beams 2 on the two sides, the two ends of the transverse bearing rope 301 are fixed on the longitudinal bearing ropes 302 on the two sides through a rope buckle, the horizontal spacing between each transverse bearing rope 301 and each longitudinal bearing rope 302 is not greater than 3 m, and the anti-falling net 4 is fixed on the transverse bearing ropes 301 and the longitudinal bearing ropes 302 through a rope binding connection mode.
[0037] In some optional embodiments, referring to Figures 1 to 3 The flexible protection device suitable for high-tower anti-falling objects of the embodiment of the application comprises the net-shaped body 3, and the anti-falling net 4 comprises an upper layer of rope net 31 and a lower layer of rope net 32 arranged at intervals, an upper layer of plane net 41 arranged on the upper layer of rope net 31, and a lower layer of plane net 42 arranged on the lower layer of rope net 32.
