Safety protection device for decelerating falling in aerial work
The invention relates to the related field of security and protection, and discloses a safety protection device for decelerating falling in aerial work. The safety protection device comprises a main body box, a safety rope cavity is formed in the main body box, the front side of the safety rope cavity communicates with a safety rope through cavity, and the front side of the safety rope through cavity is provided with a fixed pulley cavity with a downward opening in a communicating mode. A centrifugal wheel controls an upper friction block to descend to be in contact with a lower friction block, therefore, when a worker in the aerial work falls from a building accidentally, falling is decelerated under the action of friction force, the situation that in the accelerated falling process, a safety rope is tightened suddenly to generate strong elastic force and counter-impact force to injure the worker is prevented, and the worker is automatically pulled back after falling is stopped; and meanwhile, a safety rope rotating shaft is driven by a safety shaft torsion spring to rotate, so that the safety rope is always in a tightened state, and the situation that the safety rope scatters onthe ground and trips the moving worker, dangers occur, and construction is hindered is avoided.
本发明涉及安防相关领域，公开了一种高空作业用减速坠落的安全防护装置，包括主体箱，所述主体箱内设有安全绳腔，所述安全绳腔前侧连通设有安全绳通腔，所述安全绳通腔前侧连通设有开口向下的定滑轮腔,通过离心轮控制上摩擦块下降与下摩擦块接触，从而在高空作业的工作人员不慎坠楼时，实现了在摩擦力的作用下减速坠落，从而防止因加速坠落过程中安全绳突然绷紧而产生强大的弹力以及反冲击力对工作人员造成伤害，并在停止后自动将工作人员拉回去，同时通过安全轴扭簧带动安全绳转轴转动从而使安全绳始终处于绷紧状态，从而避免安全绳散乱一地绊倒移动的工作人员发生危险以及妨碍施工。
