AI Technical Summary
The existing self-locking devices for fall arrestor rails on communication towers have poor applicability, cannot adapt to different rail widths and thicknesses, and have a low safety factor when descending vertically, easily following workers as they fall.
A safety device for preventing communication tower falls was designed. By installing a first adjusting bolt and a connecting block on the lock seat, the spacing of the connecting block can be adjusted to adapt to different guide rail widths. A groove and a first guide wheel are set in the lock seat to provide resistance. Together with the brake rod and support spring, it ensures that the self-locking device has resistance when moving on the guide rail, preventing the locking block from being pulled.
The self-locking device has improved applicability and safety, and can adapt to different guide rail widths and thicknesses. It prevents the self-locking device from descending with the worker when they descend vertically, thus increasing the safety factor.
