Description
Technical field
The invention belongs to the elevator industry in special equipment field, and in particular to a kind of electricity of new fast and safely fall arrest
Terraced actuating unit.
Background technology
At present, the operation principle of elevator generally uses traction-type, i.e., is ined succession respectively car and counterweight using hoist ropes both ends,
It is wrapped on traction sheave and directive wheel, hoisting motor after decelerator speed change by driving traction sheave to rotate, by hoist ropes with draging
Tractive force caused by running wheel friction, realizes the elevating movement of car and counterweight, reaches transport purpose.It is fixed on car and leads boots
Car deflection or pendulum in operation can be prevented along the reciprocal elevating movement of fixation guide rail on building hoistway wall
It is dynamic.Normally closed block brake declutches in electric motor operation, operates elevator, is braked in the case of dead electricity, makes car stop rising
Drop, and its inactive state is maintained on stop is specified, come in and gone out for personnel and goods.Car is transporting passengers or the case of other load
Body component, counterweight are used for balancing car load, reduce motor power (output).Compensation device is used for compensating the tension force in hoist ropes motion
And weight change, make hoisting motor load stabilization, car is accurately stopped.Electrical system realizes the control to elevator motion
System, while complete to select layer, flat bed, test the speed, illuminate work.Indicate that calling system shows the direction of motion and place building of car at any time
Layer position.Safety device ensures lift running safety.
The operation principle and caused elevator accident reason in the past of traction-type traction elevator are analyzed, is not difficult to show that traction-type is led
Draw some existing deficiency of elevator.First, traction-type can be regarded as more complicated pulley mechanism, in the brake failure of traction main frame or electricity
During terraced fault, car and passenger are in a kind of runaway condition in mechanism, if now weight is more than counterweight, due to gravity
The presence of acceleration, car will make the movement of falling object downwards, thus be damaged to passenger.Second, traction-type work is former
The floor for managing elevator stops precision, although improving the degree of accuracy of stop using compensation device.But elevator running in use,
We will often find that firm mounted elevator, and car sill and landing sill are obviously leveling, in use for some time,
Car or landing sill inconsistent phenomenon occurs.This phenomenon main cause is caused to be that traction-type traction elevator is by draging
Messenger and tractive force caused by traction sheave friction.
In a word, traction-type traction elevator stops the degree of accuracy in safety, and manufacture and installation cost etc. have embodied not
Foot.Traction-type is originally the not high mechanism of reliability in structure, if elevator manufacturing enterprise arbitrarily forces down cost, reliability is just more
Customers ' Legal Right.
