Abstract
An anti-fall mechanism and a lifting transport apparatus are disclosed. The anti-fall mechanism includes a conveying platform, a linkage, an elastic mechanism, a limit switch and a self-locking mechanism. The conveying platform is installed on a lifting belt. The linkage includes a first coupler, a second coupler and two rockers, where two ends of the first coupler are rotationally coupled to two ends of the second coupler, respectively, via the rockers. The elastic mechanism is arranged between the conveying platform and the lifting belt, where one end of the elastic mechanism is connected to the first coupler, and the other end of the elastic mechanism is pressed by the lifting belt. The limit switch is arranged on the second coupler. The self-locking mechanism is arranged on the conveying platform and capable of locking and securing the conveying platform to a frame of the lifting transport apparatus.
