(57) The present invention relates to the technical field of the curing of precast concrete components, and in particular to an anti-cracking film covering device for a precast concrete component, and a film covering method. The anti-cracking film covering device comprises a film covering frame, wherein one side of the film covering frame is fixedly connected to side film covering modules distributed at the front and back; the top of the film covering frame is further fixedly connected to a horizontally arranged balance module; one side of the film covering frame is further fixedly connected to a synchronous movement module; and one side of the synchronous movement module is further fixedly connected to an obliquely arranged pressing module. In the present invention, by means of reserving a certain length of plastic film, a second hydraulic rod driving a friction plate to move downwards, and the bottom of the friction plate coming into contact with the plastic film, the purpose of fixing the plastic film is achieved; pulling the film covering frame realizes the covering of a precast component with a film by a single person; the arranged side film covering modules ensure that a side face of the precast component is pressed, thereby guaranteeing that the side face of the precast component is tightly covered with a film and ensuring the quality of the precast component; and under the action of a water pump, arranged nozzles can uniformly and stably water a surface of the precast component for curing.
