The invention discloses a fixed pulley rope anti-falling alarm device which comprises a working table, an anti-falling device is arranged at the upper end of the working table, a fixed pulley is rotationally connected to the center of the inner surface of the working table, an alarm device is arranged on the upper surface of the working table, and a camera is arranged above the working table. The rope on the outer surface of the fixed pulley needs to be driven by an external driving device to move, when the rope moves at a high speed to generate a release risk, the limiting shifting piece is driven to generate a certain degree of vibration, and meanwhile, the limiting shifting piece drives the positioning block to rotate at the same time; when the rope falls off, the rotating block is driven to rotate to a certain degree, at the moment, the rotating block pushes the trigger shifting piece to move towards the trigger switch in the rotating process, the trigger switch can be triggered accordingly to give an alarm, and people are reminded of the risk that the rope falls off.
本发明公开了一种定滑轮绳索防脱落报警装置,包括工作台,所述工作台的上端设置有防脱出装置,所述工作台的内表面中心处转动连接有定滑轮,所述工作台的上表面处设置有报警装置,所述工作台的上方设置有摄像头,本发明在使用时,需要通过外部驱动装置带动定滑轮外表面的绳索产生运动,当绳索高速运动产生脱出风险时,限位拨片将会随之被带动产生一定程度的震动,同时限位拨片将会同时带动定位块产生旋转,当定位块旋转过程中,将会随之带动转块产生一定程度的旋转,此时转块将会在旋转过程中推动触发拨片向触发开关处运动,并使得触发开关能够随之被触发从而产生报警,并提醒人们存在绳索脱出风险。
