The embodiment of the invention provides a single-row anti-falling mechanism. The single-row anti-falling mechanism comprises a door frame, a chain lifting assembly and a vehicle lifting cantilever. A chain lifting assembly is installed on the portal, and a vehicle lifting cantilever is fixedly installed at the output end of the chain lifting assembly. The chain lifting assembly comprises a sliding plate capable of vertically moving and lifting, a lifting block is fixedly installed at the top of the sliding plate, a middle movable plate is arranged in the lifting block, and one end of the middle movable plate is fixedly connected with an anti-falling hook. The anti-falling vertical plate is fixedly installed on the door frame, the anti-falling vertical plate is located at the tail end of the anti-falling hook, a plurality of positioning holes distributed at equal intervals are formed in the anti-falling vertical plate in the length direction, and one end of the anti-falling hook is embedded into the positioning holes; the top of the movable plate is elastically connected with the top of the lifting block through a spring. According to the single-row anti-falling mechanism, economic losses and casualties caused by sudden breakage in the use process of the chain can be well prevented through the anti-falling structure, and the use safety coefficient is increased.
