Abstract
The invention discloses a falling protecting device for a rail-type lifting scaffold and aims to provide a falling protecting device which uses a steel wire rope as a trigger and is simple in structure, flexible and reliable. A guide rail is formed by connecting two slide rails through a plurality of connecting posts which function in protecting fall and holding. Guide wheels are mounted on a guide base. The lower end of an L-shaped falling protector is connected with the guide base through a tension spring, the upper end of the falling protector is a free end, and the middle of the falling protector is hinged to the guide base. One end of a safety pull hook is hinged to the upper end of the falling protector, the other end of the safety pull hook is hooked to a steel wire rope of a lifting mechanism during descending of the scaffold so that the falling protector is pre-tightened, and the guide rail is fixedly connected with a main frame of the scaffold. The falling protecting device uses the steel wire rope as a falling protection trigger, the falling protector is pre-tightened, and accordingly triggering is flexible, and reliability is high. By pre-tightening, a gap is reserved between the falling protector and a connecting column when the scaffold descends, and normal movement of the scaffold is guaranteed.
