Anti-falling device
The invention discloses an anti-falling device which is used for preventing a truss from falling, wherein the truss comprises a truss body and a limiting truss which are fixedly connected with each other; the limiting truss comprises two vertically-arranged straight rods, and a plurality of transverse rods which are parallelly arranged between the two straight rods; the anti-falling device comprises a fixing frame, limiting blocks, a star wheel and a hook; two limiting blocks are respectively fixed at the left end and the right end of the fixing frame; a groove is formed in the middle of each limiting block along the vertical direction; each groove is matched with the corresponding straight rod of the limiting truss; the star wheel and the hook are respectively fixed on the fixing frame through a rotary shaft; the star wheel is uniformly provided with a plurality of star teeth along the circumferential direction; each of the star teeth and the hook is provided with a baffle block; the baffle block on each star tooth is butted to the baffle block on the hook when the star wheel rotates. The anti-falling device disclosed by the invention has the advantages of simple structure, convenience in operation and capability of effectively preventing the truss from falling.
