Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, an elevator emergency rescue apparatus includes a hoistway 1, a car 2 in the hoistway, and an elevator operation control cabinet 3. A supporting beam 4 is arranged at the top of the well 1, an emergency driving device is arranged on the supporting beam 4, and a normal working system and an emergency rescue system are arranged in the elevator operation control cabinet 3.
The emergency driving device comprises a speed reducing motor 5, a traction sheave 6, a steel wire rope and a balancing weight 8; the traction sheave 6 and the speed reducing motor 5 are fixed on the support beam 4, the speed reducing motor 5 drives the traction sheave 6 to rotate, the steel wire rope is wound on the traction sheave 6, one end of the steel wire rope is connected with the balancing weight 8, and the other end of the steel wire rope is connected with the lift car 2; and band-type brake devices 7 are arranged on two sides of the traction wheel 6.
An emergency rescue operation button 10 and a voice player 11 are arranged inside the car 2, and a speed sensor 13 and a blind floor recognition device 12 are further arranged on the outer side wall of the car 2.
The emergency driving device further comprises an emergency power supply 9, and the emergency power supply 9 is respectively connected with the speed reducing motor 5, the emergency rescue operation button 10 and the voice broadcast device 11 through circuits.
The speed sensor 13 and the blind floor recognition device 12 are respectively connected with the input end of an emergency rescue system, and the speed reduction motor 5 and the voice broadcast device 11 are respectively connected with the output end of the emergency rescue system.
