8. The use method of the barrier-free anti-falling device suitable for light steel roof construction is characterized in that: the method comprises the following steps:
s1, clamping two groups of edge assemblies (210) on ribs on the top of the light steel roof by using a first buckle main part (214) and a first buckle auxiliary part (215) respectively, inserting steel wire ropes between through cavities on the same side of first anchoring boxes (211) on two sides, enabling the steel wire ropes on two sides to be in a nearly parallel stretched state by using a U-shaped anchoring bolt (216), equally installing a plurality of groups of supporting assemblies (220) below the steel wire ropes by using a second buckle main part (225) and a second buckle auxiliary part (226) in the same way, correspondingly clamping the steel wire ropes into rope grooves on two sides of the top of a second anchoring box (221) by using a limiting plate (222), wherein the included angle between a first wing plate (213) and a second wing plate (224) is adjustable, and the first buckle main part (214) and the second buckle main part (225) which are correspondingly connected are in a rotary connection mode, so the device can adapt to the construction environment of the light steel roof with different rib intervals, the use is more convenient, and the adaptability is stronger;
s2, placing the traction device (1) above the space between the two steel wire ropes, and connecting side sliding buckles (105) on two sides of a base (103) at the bottom of the column box (101) through hexagon socket head bolts respectively so that the steel wire ropes on two sides are clasped between the side sliding buckles (105) on two sides;
s3, connecting the buckle end of the safety rope belt (116) with personnel through a section of safety belt, wherein the inner cavity of a buckle holding structure formed by the base (103) and the lateral slide buckles (105) on the two sides is slightly larger than the cross-sectional area of the combined body of the second anchoring box (221) and the limiting plate (222), so that the personnel can achieve the barrier-free construction purpose that the personnel is not blocked by the supporting component (220) when dragging the traction device (1) by walking;
s4, during normal construction, due to the design of the safety belt and the safety rope belt (116) capable of storing force and self-contracting, compared with the roof life line device in the traditional technology, the construction range is expanded by workers, and the barrier-free construction capability is further improved;
s5, when a person falls unfortunate, the main shaft (109) rotates rapidly due to the extremely rapid dragging action, and then the ratchet (113) inside the anti-falling releasing body (112) is immediately thrown out of the square cavity of the anti-falling releasing body (112) due to the inertia action and is clamped in the tooth gap of the ratchet ring (111), so that the continuous extension of the safety rope (116) is prevented, the person is ensured not to continuously fall downwards, and the safety protection purpose is achieved;
s6, simultaneously, due to the close contact between the ratchet (113) and the ratchet ring (111), a complete switch-on closed circuit is formed between the ratchet ring (111), the storage battery (107), the buzzer (108), the electric slip ring (110), the spring (114) and the ratchet (113), so that the buzzer (108) can immediately send out a buzzing alarm to remind workers and friends to assist rescue, compared with the traditional roof life line device, the device has richer functions and more guarantee in use.
