The specific rescue process of the invention is as follows: when the wide-angle camera shoots that a person falls, the wide-angle camera sends the shot first falling height position, the shot second falling height position and the collection interval time between the first falling height position and the second falling height position to the control device for calculation, the control device calculates the falling height distance of the lifting platform 3 and the safety time for the person to fall according to the obtained first falling height position, the obtained second falling height position, the obtained collection interval time between the first falling height position and the second falling height position and the preset safety falling height, and then the downward movement speed of the lifting platform 3 is calculated so as to drive the anti-falling plate 4 on the lifting device to move to the lower part of the falling personnel within the specified time and turn inwards to the horizontal position to catch the falling personnel, and the caught personnel are stably delivered to the cabin floor.
Now, specific examples are given: if the first falling height position is h1The second falling height position is h2The acquisition interval between the first falling height position and the second falling height position is Δ t, assuming that the actual falling height position of the person is h0Person from h0Fall to1The time required for the height position is t1The height of the falling person is s, and the height position of the falling person to be caught by the falling-preventing plate is h3Person from h2The time required from falling to being caught is t0The lowest speed of the falling-preventing plate is v0Then v is calculated according to the following formula0The value of (c):
h3＝h0+s (4)
the lowest speed of the lifting platform driven by the lifting device must be more than v0So as to timely catch the falling personnel within the safe falling height distance range, avoid casualty, and then stably convey the caught falling personnel to the bottom of the cabin.
The height position in the invention is based on the cabin roof, e.g. the actual falling height position h of a person0Refers to the vertical distance from the actual location of the person falling to the ceiling of the cabin.
When the control device monitors that the personnel safely reach the bottom of the cabin through the wide-angle camera, the control device automatically controls the lifting driving device 22 to move upwards to enable the scissor lifting frame 21 to be folded and contracted to the top of the cabin so as to reduce the occupied space of the hatch anti-falling device, then the overturning driving device 5 is driven to rotate, the anti-falling plate 4 is enabled to overturn outwards by 180 degrees, a passing channel between the hatch and the bottom of the cabin is reserved, and the normal passing of the personnel is avoided.
In conclusion, the hatch anti-falling device can timely rescue high-altitude falling personnel, avoid falling injuries and greatly protect the personal safety of the crew.
In conclusion, the present invention effectively overcomes various disadvantages of the prior art and has high industrial utilization value.
