It is connected in second pulley 5, the other end of the 5th steel wire rope 23 is successively around the hook 26 of the hook of second pulley 5, first 25 and second
Afterwards, it is fixed on the 3rd pulley 10；Along from the second longeron 4 to the direction of the 3rd longeron 8, the second longeron 4 and the 3rd longeron 8
The 3rd hook 27 and the 4th hook 28 are sequentially provided with, one end of the 6th steel wire rope 24 is fixed in first pulley 2, the 6th steel wire rope
After 24 other end links up with 28 around the hook of first pulley the 2, the 3rd 27 and the 4th successively, it is fixed on the 6th pulley 16；One
Motor drives the 3rd pulley 10 to rotate by the 3rd longeron 8, and another motor drives 16 turns of the 6th pulley by the 6th longeron 14
It is dynamic.Velocity sensor 17 and motor are connected with PLC signal.
During using the third embodiment of emergency rescuing system of the present invention, by first crossbeam 3, the first longeron 1 and the second longeron 4
Elevator well headroom is both secured to, PLC is installed in elevator(lift) machine room, by second cross beam 12, the 3rd longeron the 8, the 6th
Longeron 14 and velocity sensor 17 are installed on the bottom surface of elevator hoistway, and four hooks are respectively arranged in into elevator hoistway
In side wall, being respectively mounted one on four seamed edges parallel with the first longeron 1 of the outside of lift car 6 can be around own axis
Rotating shaft 7, in the running of lift car 6, if breaking down, when lift car 6 quickly falls, velocity sensor 17 detects
The downstream rate of lift car 6 is abnormal, and caused signal is transferred into PLC, and PLC starts two electricity simultaneously
Machine, two motors involve the 5th steel wire rope 23 and the 6th steel wire rope 24 respectively, the 5th steel wire rope 23 and the 6th steel wire rope 24 from
Depart from hook, and tense respectively, intersection is respectively formed above and below lift car 6, as shown in figure 9, now, the 5th steel
The steel wire rope 24 of cord 23 and the 6th forms relative web tension, forms the slip cableway after lift car falls.Work as used during elevator falling
Afterwards when being slided on netted cableway, four rotating shafts 7 on lift car 6 rotate, and prevent steel wire rope because of impact and frictional force too
It is broken greatly, while prevents steel wire rope cutting lift car 6 and injure boarding personnel.Because network structure has very strong elasticity resistance
Power, to falling, lift car forms cluster lifting force, and makes lift car even retardation, until lift car deceleration of falling
To halted state.
All motors in emergency rescuing system of the present invention are the three phase electric machine or two-phase induction motor that one direction rotates.
When setting emergency rescuing system of the present invention in elevator hoistway, can install one in stair shaft shaft bottom has bullet
The barrier of property, and several rubber safety air bags are placed below the barrier, cause personnel to slip when there are elevator faults
When falling into elevator, elastic barrier forms the first buffering, and rubber safety air bag forms secondary buffer, to protect pendant to greatest extent
Enter the personnel in elevator hoistway.
Emergency rescuing system of the present invention can be first during falling accident or personnel's falling accident occur for elevator and lift
Time carries out emergency relief, free fall type is fallen（Slide）Elevator and lift carry out " even deceleration ", until elevator and
Lift stops falling, and realizes effective fanout free region rescue.
