Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIGS. 1 to 3 , the first embodiment of the present invention provides a high-altitude emergency anti-falling device for a construction site, including a falling state monitoring device, a pop-up device, a safety rope net protection device, and an installation package 3, which is ejected. The device and the safety rope net protection device are both arranged in the installation package 3, and the ejection device is respectively connected with the falling state monitoring device and the safety rope net protection device. tied to the human body.

The construction safety of high-altitude operators is guaranteed in real time. When a high-altitude fall occurs due to operation errors, the present invention starts immediately, automatically triggers the protection mechanism to eject the rope net, and prevents personnel from falling through winding and suspension.

Further, the falling state monitoring device includes one or any combination of a speed sensor, an acceleration sensor and a displacement sensor; for monitoring whether the human body falls from a height, directly or Indirectly judge the state of the human body. If it is in weightlessness or other falling states, the protective mechanism will be activated, so that the ejection device will be activated.

Further, the safety rope net protection device includes a safety rope net 1 and a traction head 2, the traction head 2 is arranged at the outer end of the safety rope net 1, and the safety rope net 1 is connected with the installation package 3; It is detected by the sensor that the human body falls and reaches a certain speed. At the same time, the protective mechanism is triggered, the action of the ejection device is controlled, and the rope net traction head 2 is ejected, which drives the rope net to launch and unfold in a specific direction. The head 2 is automatically coiled due to inertia, and the net can also hang on obstacles such as scaffolding and steel bars to prevent people from falling.

Further, the number of traction heads 2 is multiple, and the multiple traction heads 2 are evenly distributed on the outer end of the safety rope along the circumferential direction.

Further, the pulling heads 2 are evenly distributed with the rope ends extending from the periphery of the rope net.

Further, the high emergency anti-falling device is arranged on the safety rope net protection device or the installation bag 3, or is separately bound to the human body.

Further, the binding mechanism is the protective vest 4 .

Further, the ejection device is provided with an ejection track, and the traction head 2 is arranged in the ejection track; the traction head 2 is connected with the rope net, and is used to drive the rope net to unfold and be wound on the obstacle, and the ejection track is connected with a gas explosion. source or hydraulic power source, or shrapnel, by detonating the gas explosion source or hydraulic power source or shrapnel, the pulling head 2 is ejected from the ejection track.
