When the rotating disc 9 is at rest, the spring 8 is in a stretched state, so that the friction slider 7 does not move outwards. When the rotating disk 9 rotates, the friction sliding block 7 has a tendency of flying away outwards, the centrifugal force increases with the increase of the rotating speed of the rotating disk 9, and when the rotating speed of the disk reaches 155.7r/min, namely the descending speed is about 1 m/s. The centrifugal force just makes the friction slider 7 contact with the friction groove 23 and generates enough friction force to make the human body descend at a speed of about 1 m/s. Then, as the winding radius of the bobbin is smaller and smaller, the descending speed of the human body is smaller, and therefore the falling and landing of the human body are facilitated. When the descending speed is reduced to 1m/s, the centrifugal force of the friction slide block 7 is smaller than the pulling force of the spring 8, the spring 8 contracts, the friction slide block 7 is pulled back to the inner side, if the speed of the rotating disk 9 is increased again, the friction slide block 7 decelerates the rotating disk again, and the speed of the rotating disk 9 is controlled within the range of about 1m/s repeatedly, so that the purpose of stabilizing the speed is achieved.
The utility model discloses can satisfy many people and use. The second bobbin 18 of the first bobbin 17 in the device can rotate in the positive and negative directions at the same speed, and the special double-bobbin structure can meet the requirement of recycling of multiple persons and save lives of more persons within limited time.
The utility model discloses set up and press from both sides tight iron sheet 3 and chucking spanner 4, pin escape device drive mechanism before human whereabouts, make human safety stop aloft, wait for human position stabilization back, open chucking spanner 4, the human body begins to descend, and escape device just begins work. The application of the device can ensure that the human body can stably slide downwards from the beginning without the left-right swinging uncertainty, thus avoiding the injury of the human body caused by the collision with the building.
In this embodiment, the high-rise escape device is fixed on the top of the building through the lifting lug 2, and at the beginning, two ropes are respectively wound on the first bobbin 17 and the second bobbin 18, and the winding directions are opposite. Then the clamping wrench 4 of the safety locking device is lifted up to lock the transmission mechanism. The escaper No. 1 hangs the rope on the body on the hook of the rope on the second bobbin 18, and after the human body is stabilized in the air, the clamping wrench 4 of the locking device is pulled down to descend for escaping. As the second spool 18 rotates, the first spool 17 simultaneously rotates in the same direction, and the rope of the first spool 17 is automatically retracted. When the person to be escaped No. 1 falls to the ground, the length of the first bobbin 17 is just the height of the roof where the person is located, and conditions are created for the escape of a second person. Treat that the escaper 1 number relieves the rope couple, the escaper 2 numbers can be followed the couple of first spool 17 and flee, when first spool 17 is transferred, second spool 18 is automatic to be packed up, treat that the escaper 2 numbers falls to ground, the length that second spool 18 packed up is the floor height of place just, has created the condition for 3 rd individual flees, then the escaper 3 numbers can use the couple of second spool 18 to flee, so circulate, can satisfy many people and flee.
