The roof fall prevention ladder device (1) of the present invention is composed of a safety rope block (50) having a safety wire (53) connected to a worker who has climbed onto the roof (201) through a fall prevention part (40), and a lower fixing part (30) that is connected to the roof (201) of a building (200) by a rotating structure and is attached to the roof (201) of a building (200) from top to bottom, thereby having the feature of preventing fall accidents caused by roof collapse when working on the roof (201) of a building (200) such as a livestock barn where it is difficult to use an aerial work vehicle.

This invention relates to the field of building construction technology and discloses a hoisting construction process with fall arrest locking for prefabricated buildings, comprising the following steps: S1, pre-hoisting preparation and intelligent verification; S2, component hooking and status self-check; S3, lifting and full-process active fall arrest monitoring; S4, judgment and execution of multi-level fall arrest locking mechanism; S5, precise positioning and intelligent assisted docking; S6, safe unlocking and installation confirmation; S7, data recording and process iteration. This invention, by introducing an intelligent decision and control unit, a multi-sensor fusion perception system, and a multi-level fall arrest locking mechanism, achieves intelligent monitoring and active safety protection throughout the entire hoisting process. It significantly improves hoisting safety by implementing a layered response from risk warning to emergency locking through three-level fall arrest locking, especially in the event of electrical control failure, where it can still quickly lock through purely mechanical means, effectively preventing fall accidents.

This invention discloses an intelligent safety locking system for preventing falls during high-rise building construction, belonging to the field of construction safety technology. The system integrates inertial navigation, pressure sensing, and visual recognition technologies to monitor the movement trajectory and posture deviation of workers in real time. When abnormal acceleration or instability tendency is detected, the control unit triggers the electromagnetic locking mechanism of the guide rail based on a risk prediction model, achieving dynamic anchor point rigid fixation within 50ms, forming multi-point constraint protection. A narrowband Internet of Things (IoT) network is used to construct a human-machine-environment collaborative monitoring network, combined with an adaptive algorithm for construction scenarios to optimize the locking threshold. This system supports continuous protection during horizontal / vertical multi-dimensional movement, increasing the fall intervention success rate to 99.6% and reducing the maximum buffer impact force to below 15% of the human tolerance threshold. Through intelligent early warning and active braking mechanisms, it significantly reduces the fall accident rate, providing all-weather active safety protection for the construction of super high-rise buildings.
