Description
Technical field
The utility model relates to a kind of building hoist, relates in particular to a kind of gradual anti-falling safety device for elevator.
Background technology
The gradual anti-falling safety device of building hoist is a kind of safety device that belongs to building hoist.In skyscraper, elevator is to realize people, the requisite main equipment of goods vertical transport.Because adjustable height is high, weight is larger, therefore danger is also larger in use.Since other factors when causing cage to fall this device move, prevent from that cage from dropping to cause casualties, play the safety guard-safeguard effect.What adopt in building hoist at present is the moment anti-falling safety device, although simple in structure, opening time short, owing to be that moment is anti-fall, force of inertia is large, makes easily that the people is injured, the damage guide rail bracket.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of simple in structure, mild, the failure-free gradual anti-falling safety device for elevator of braking solves that the moment braking produces that inertia makes easily that the people is injured, the easy problem of damage of guide rail bracket.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is:
A kind of gradual anti-falling safety device for elevator, comprise progressive swelling device 1, progressive safe body 3, guiding is tiltedly carved piece 4, reset attachment 5, progressive anti-fall pinch wheels 6, sliding feet 7, gravity rollers 8, brake shoe 9, an end of progressive swelling device 1 is connected with progressive anti-fall pinch wheels 6, progressive safe body 3 bottoms are connected with sliding feet 7 by gravity rollers 8, sliding feet 7 is welded on the girder of cage top, and progressive safe body 3 one sides are welded with reset attachment 5, and guiding is tiltedly carved piece 4, brake shoe 9 is captiveed joint with progressive safety device body 3.
The top of described progressive safe body 3 installs and fixes guide-localization wheel 2, makes gradual anti-falling safety device for elevator not scrape the damage guide rail in slip.
Described guiding is tiltedly carved piece 4, brake shoe 9 and is done by high strength bolt and progressive safety device body 3 respectively and be rigidly connected.
Be processed with grid pattern on the double curved surface of described progressive anti-fall pinch wheels 6, rotate and move up when the guide rail with standard knot rubs, drives progressive anti-fall pinch wheels.
Principle of work of the present utility model: progressive swelling device is connected with sheave shaft one end of large pulley by disconnected rope linkage with an end of guide rod, the top of progressive safe body installs and fixes the guide-localization wheel by the high strength bolt of M16 * 50, progressive safe body bottom is by the high strength bolt of quadruplet M16 * 50, two gravity rollers are made free-running fit and are connected with sliding feet, guiding is tiltedly carved piece, brake shoe is used respectively the high strength bolt of two M16 * 50 and progressive safety device body to do and is rigidly connected, the face of cylinder that progressive anti-fall pinch wheels is tiltedly carved piece along guiding moves up and down, realized the jam-packed with the standard knot guide rail, impel the progressive safety device body to move by the sliding feet direction guiding rail, realize braking.
When falling when wire cable rupture or owing to other reason cage Accidental occurrence, the steel rope large pulley moves down under the effect of tension spring, the work of disconnected rope linkage, excite the progressive swelling device in the anti-falling safety device, spurring progressive anti-fall pinch wheels by the guide rod in the progressive swelling device in the effect of tensioner spring moves up, progressive anti-fall pinch wheels moves up along doing on the face of cylinder of tiltedly carving piece of leading, because it is up big and down small that guiding is tiltedly carved the face of piece, more up mobile space is less for progressive anti-fall pinch wheels, gripping power is just larger, has played progressive effect.Progressive anti-fall pinch wheels is when moving up and contacting with the standard knot guide rail, cage falls downwards simultaneously, the guide rail that is processed with latticed coarse line and standard knot on the progressive anti-fall pinch wheels double curved surface rubs, drives progressive anti-fall pinch wheels and rotates and move up, because guiding is tiltedly carved the guide rail of piece and standard knot and is presented little lower broad gap, the progressive anti-fall pinch wheels gap that more moves up is less, moment the gap be zero.Because the gravity pressure of cage is increasing, force the progressive safety device body by the displacement of sliding feet direction guiding rail, at this moment brake shoe contacts with guide rail.Simultaneously brake shoe with guide rail, progressive anti-fall pinch wheels, lead and tiltedly carve piece and mutually clamp, under the deadweight of cage, the heavier cage of cage more down, gripping power is larger, has so just realized that cage rests on the guide rail of standard knot, has played the effect of safe fall-proof.
When gradual anti-falling safety device for elevator need reset, the cage work of normally rising, because rising, large pulley make progressive swelling device by the work of disconnected rope linkage, the gradual anti-falling pinch wheels is moved down, pressure spring in the reset attachment ejects forward progressive safe body is resetted, brake shoe leaves guide rail, and the elevator progressive safety device is in normal condition at this moment.
The beneficial effects of the utility model are: adopt progressive anti-fall pinch wheels, by large pulley triggering, progressive swelling device work, make retro-speed accurately, gently, the people is difficult for injured in cage, solved moment braking generation inertia and made easily the problem that the people is injured, guide rail bracket damages, simple in structure, reliable in action.It is tubular type, channel-section steel formula, angle steel formula guide rail that this gradual anti-falling safety device for elevator is applicable to guide rail.
