The invention relates to the technical field of braking equipment, and discloses an anti-falling safety device for a construction elevator. Sliding grooves are uniformly formed in the outer ring of a conical hub, friction blocks are movably connected into the sliding grooves in a sleeved mode, a centrifugal rotating block seat is fixedly connected to one side, close to a shell, of a gear through a shaft, a strip-shaped magnet is fixedly mounted in the middle of the centrifugal rotating block seat, electromagnets are symmetrically and fixedly mounted at the positions, located at the top and the bottom of the strip-shaped magnet, in the centrifugal rotating block seat, rotating cavities are vertically and symmetrically formed in the positions, located at the end part of a centrifugal block, in the centrifugal rotating block seat, rotating rods are movably mounted in the rotating cavities, magnet sets are respectively and fixedly mounted at the positions, corresponding to conductive heads, of the top and the bottom of the inner wall of the shell, and short rods at the bottoms of the rotating rods are clamped in clamping grooves. According to the anti-falling safety device, the strip-shaped magnet is arranged to be matched with the centrifugal block to work, an electromagnet structure for limiting the centrifugal block is further arranged, the structure and the installation of a friction block are adjusted, the braking effect and precision of the anti-falling safety device can be improved, and the safety is guaranteed.
