[0047] This specific implementation method is used in the following way:

[0048] 1. Measure the length according to the position of the tower crane that needs to be protected, and assemble several anti-falling nets 1 according to the measured length. During assembly, insert the connecting rope 2 into the connecting ring 1-4 of the connecting sleeve 1-3 of two adjacent anti-falling nets 1, so that the two adjacent anti-falling nets 1 are connected through the connecting rope 2. At this time, the assembly of the anti-falling net mechanism is completed.

Insert the support rod mechanism 3 into the connecting sleeves 1-3 at both ends of the anti-fall net mechanism, so that the support rod 3-2 of the support rod mechanism 3 is inside the connecting sleeves 1-3.

[0050] When the two support rod mechanisms 3, the inner wire rope reel 4 and the outer wire rope reel 5 are fixed, the winding drum 4-3 is locked by rotating the inner wire rope reel 4 and the outer wire rope reel 5. The stability of the anti-falling net body 1 is improved by tightening the wire rope. At the same time, when the inner wire rope reel 4 and the outer wire rope reel 5 fail, the wire rope locker 6 can ensure that the wire rope does not become loose or fall off.

[0051] In order to improve the safety performance, another fixing method in this specific implementation is: one end of the wire rope of the inner wire rope winder 4 can be installed on the tower crane bracket through a fixer, at this time, both ends of the wire rope can be connected to the tower crane, and at the same time, there are wire rope lockers 6 on both sides of the wire rope to achieve secondary protection, and one end of the wire rope of the outer wire rope winder 5 is also connected to the tower crane bracket, which can improve the overall strength of the anti-fall net mechanism.
