Description
Technical field
The invention belongs to the elevator industry in special equipment field, be specifically related to a kind of elevator power mechanism of novel fast and safely fall arrest.
Background technology
At present, the principle of work of elevator generally adopts traction-type, namely hoist ropes two ends are used in succession respectively car and counterweight, be wrapped in traction sheave and track adjusting wheel, hoisting motor is by driving traction sheave to rotate after retarder speed change, by hoist ropes and the fricative tractive force of traction sheave, realize the dipping and heaving of car and counterweight, reach transport object.The boots of leading be fixed on car can along the reciprocal dipping and heaving of fixed guide be arranged on building hoistway body of wall, prevents car to be in operation deflection or swing.Normally closed block brake declutches when electrical motor works, and elevator is operated, and brakes in dead electricity situation, makes car stop lifting, and maintains its quiescence on appointment stop, comes in and goes out for personnel and goods.Car is the box part of transporting passengers or other load, and counterweight is used for balancing car load, reducing motor power (output).Compensating device is used for compensating the tension force in hoist ropes motion and changes in weight, and make hoisting motor load stabilization, car is able to accurate stop.Electric system realizes control to elevator motion, completes simultaneously and selects layer, flat bed, tests the speed, illumination work.Indicating call system shows sense of motion and the place floor position of car at any time.Safety device ensures lift running safety.
Analyze the principle of work of traction-type traction elevator and the elevator accident reason in the past produced, some deficiency showing that traction-type traction elevator exists of being not difficult.One is, traction-type can be regarded as more complicated pulley mechanism, when the brake failure of traction main frame or lift circuit fault, car and passenger are in a kind of runaway condition in mechanism, now weight is greater than the words of counterweight, due to the existence of acceleration due to gravity, car will do the movement of falling object downwards, damages thus to passenger.Two are, the floor of traction-type principle of work elevator stops precision, although adopt compensating device to improve the accuracy of stop.But during elevator running uses, we often can find firm mounted elevator, and car sill and landing sill are obviously leveling, in use for some time, there will be car or landing sill inconsistent phenomenon.Cause this phenomenon major cause to be just, traction-type traction elevator is by hoist ropes and the fricative tractive force of traction sheave.
In a word, traction-type traction elevator, in safety, stops accuracy, and the aspects such as manufacture and cost of installation embody deficiency.Traction-type is originally exactly structurally the not high mechanism of reliability, if elevator manufacturing enterprise arbitrarily forces down cost, and reliability just more Customers ' Legal Right.
