Abstract

A vertically movable smart safety guardrail comprises two main frames (1), two vertically movable frames (2), and multiple protective ropes (15). The vertically movable frame (2) is slidably connected to an upper end of an inner side of the main frame (1). The protective rope (15) is connected between the two vertically movable frames (2). A first driving motor (3) is fixedly mounted at the bottom of a front side surface of the main frame (1). A lower synchronization pulley (4) is mounted on an output shaft of the first driving motor (3). An L-shaped mounting plate (5) is fixedly connected to the front side surface of the main frame (1) by means of a bolt. The guardrail has a simple container-shaped structure and a neat and novel appearance. The vertically movable frame moves vertically so as to place and remove the protective ropes, enabling automatic management of a space that passengers are allowed to pass through at intervals. The invention has a wide range of applications, a low failure rate, a long service life, and high safety. The guardrail uses the protective rope having a flexible structure, and does not sag when spanning a large distance, achieving high safety, and thereby solving the problem of the heavy weight of a hard linking member, and overcoming the defect of sagging of a flexible structure.
