AI Technical Summary
In current construction, workers need to frequently perform hook-and-hook operations, which affects work efficiency and hook strength, leading to wear and tear.
A fall protection mechanism for construction work was designed, which adopts a ring-shaped fall protection plate and an auxiliary moving mechanism. Multiple rollers are used to realize the continuous movement of the hook, reducing the frequency of hooking and unhooking operations. Lateral movement is achieved through the rolling contact between the rollers and the guard rod.
It improves the mobility of staff, reduces physical exertion and time waste, avoids wear and tear on hooks and guardrails, and enhances the practicality and safety of the mechanism.

Abstract
Claims
1. A construction fall protection mechanism, comprising a protective pole (1), characterized in that: The outer surface of the protective rod (1) is fitted with an annular anti-fall plate (2), and the lower surface of the annular anti-fall plate (2) is welded with an installation plate (3). The lower end of the installation plate (3) is provided with a circular hole (4). The auxiliary moving mechanism is set inside the annular fall arrestor plate (2). The auxiliary moving mechanism includes two semi-annular plates (5) and multiple rollers (6). The front and rear surfaces of the annular fall arrestor plate (2) are provided with threaded grooves (7). The two threaded grooves (7) are connected to the interior of the annular fall arrestor plate (2). The interior of the two threaded grooves (7) is threaded with threaded rods (8). The two semi-annular plates (5) are respectively installed at the near ends of the two threaded rods (8). The two semi-annular plates (5) are located inside the annular fall arrestor plate (2). The two semi-annular plates (5) are located on the outer surface of the guard rod (1). The two semi-annular plates (5) are arranged in a front-to-back mirror configuration. Multiple mounting grooves (9) are provided on the near surfaces of the two semi-annular plates (5). Multiple rollers (6) are respectively rotatably installed inside the multiple mounting grooves (9).
