The invention discloses a power-off and anti-falling dual-function electric
tower construction anti-falling device, and relates to the technical field of electric
tower construction, the power-off and anti-falling dual-function electric
tower construction anti-falling device comprises a circular
barrel shell, a winding motor is installed on the rear side of the circular
barrel shell, and a dual-function anti-falling
assembly is arranged on the lower side of the circular
barrel shell; a safety
rope lubricating
assembly is arranged on the lower side of the double-function anti-falling
assembly, the double-function anti-falling assembly comprises a shell connected to the lower side of the circular barrel shell, and a bottom plate is installed at the bottom of the shell through bolts. According to the electric tower construction anti-falling device with the power-off and anti-falling dual functions, when a winding motor breaks down, an output shaft of the winding motor loses self-locking force to cause falling, and when a speed detection sensor detects that a safety
rope falls rapidly, a strong
electromagnet is powered off, so that an arc-shaped inner toothed plate is clamped on a gear to lock a winding roller, and the safety of the safety
rope is ensured. Therefore, the anti-falling function is achieved, the anti-falling function can be achieved no matter when power is
cut off or the winding motor breaks down, and safety is greatly improved.
