Description
Technical field
The utility model is related to elevator emergency escape device.
Background technology
Elevator is the necessary equipment of skyscraper, it is well known that it is strict to meet that a safety device is included in elevator requirement
Safety requirements and tightened up safety rule, typical safety device is that brake is set between car and car guide rail,
Brake is adapted to and freely declines parking from emergency, such as has a power failure or because the speed of failure is adjusted and car speeding, generally
In the case of occur emergency when, activate brake after, elevator technician is called into control room manual actuation driving wheel to be lifted
Or the brake that resetted behind floor of the reduction car needed for, so as to elevator is returned into SBR, but this program is very not
The convenient and more unfortunate passenger before technician reaches that is possible to has the danger of death, in addition after brake is activated, due to
Friction load deficiency between hoisting line and driving wheel causes main motor to rotate, and traditional elevator depends on main motor as driving
Source, this can be caused when power failure or main motor failure passenger escape are impossible.
The content of the invention
Engaged by between gear when the technical problems to be solved in the utility model is powered off, pressure roller be pressed into hoisting line,
Start connecting rod and release brake, closing switch starts standby motor reduction car and reaches predetermined floor, ensures the peace of passenger
Entirely.
In order to solve the above-mentioned technical problem, the utility model is using technical scheme：Elevator emergency escape device.
Elevator emergency escape device, including：Gear is installed in driving wheel front end, and connecting rod is connected to brake bar, drives
Running rope one end terminates in car walls, and the other end is connected to pivoting lever one end, and electromagnetic brake is arranged on and drives on rope, forward and backward convex
Wheel is adjacent with pivoting lever, connecting rod respectively, and switch is adjacent with rear cam, and pivoting lever and forward and backward cam are connected by axle 1, preceding,
Actuator is respectively installed in forward and backward cam lower section afterwards, and standby motor is arranged on before preceding actuator, and little gear is located at forerunner
Behind moving part, multiple pressure rollers are arranged on the top of hoisting line, and axle 2 rotatably connects forward and backward actuator, little gear and pressure roller
Connect.
Described connecting rod is located at the top of brake.
Described pressure roller has an annular groove.
Advantage to be solved in the utility model and beneficial effect are：Engaged by between gear during power-off, pressure roller is pressed into
Hoisting line, starts connecting rod and releases brake, and closing switch starts standby motor reduction car and reaches predetermined floor, and guarantee multiplies
The safety of visitor.
