Energy-saving building construction lifting anti-falling device

The invention provides an energy-saving building construction lifting anti-falling device, and relates to the technical field of building construction equipment. The problems that after a steel wire rope is broken, a hanging frame is prone to falling rapidly, casualties are caused, and the hanging frame cannot be automatically locked through structural improvement when the steel wire rope is suddenly broken; and the adjusting efficiency of a manual locking structure is low, and automatic locking cannot be achieved after adjustment are solved. The energy-saving building construction lifting anti-falling device comprises a frame body, wherein a lifting frame is slidably connected into the frame body, the steel wire rope is connected to the lifting frame, and a protection structure is mounted on the lifting frame; and a stress rod makes elastic contact with the steel wire rope, when the stress rod is located at the initial position, a clamping block and a stop block are in a clamped state, thus after the steel w
