Electric tower construction anti-falling device with power-off and anti-falling functions

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of electric tower construction, in particular to an electric tower construction anti-falling device with dual functions of power-off and anti-falling. Background technique [0002] Electric towers are trapezoidal, triangular and other tower-shaped buildings, usually 25-40 meters high, and are steel frame structures. Most of them are built near power plants and distribution stations in the wild. It is an important facility in the power sector. It can protect and support overhead wires. The design, manufacture, installation, maintenance and quality inspection of power towers are important guarantees for the operation and development of modern power systems. Power towers need to be inspected and repaired. [0003] When maintenance personnel carry out maintenance on the electric tower, if a power failure occurs, the shaft of the motor will lose its self-locking ability, so the safety rope will lose its self-lo...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a dual-function power-off and anti-fall anti-fall device for electric tower construction, which solves the problem of maintenance personnel in electric towers. When performing maintenance on the ground, if a power failure occurs, the shaft of the motor will lose its self-locking ability, so that the safety rope will lose its self-locking ability, causing the maintenance personnel to fall.
