Description of drawings
Fig. 1 is the utility model at the structural representation of on-position not.
Fig. 2 is the structural representation of the utility model in on-position.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: centrifugal wheel 2 is rotationally connected on installing plate 1, on the installing plate 1 of centrifugal wheel 2 one sides, be provided with the pinch wheels 3 that cooperates with centrifugal wheel 2, on centrifugal wheel 2, be hinged with centrifugal 5 by first bearing pin 4, be provided with elastic tension apparatus between centrifugal 5 centrifugal and the centrifugal wheel 2 or between two centrifugal 5 the centrifugal portion, on installing plate 1, be fixed with brake block 6, on installing plate 1, be rotatably connected to the eccentric wheel 8 that cooperates with brake block 6 by second bearing pin 7, on eccentric wheel 7, be provided with and drive eccentric wheel 8 and rotate the spring assembly that its eccentric part is drawn close to brake block 6, on installing plate 1, be provided with the eccentric part that makes eccentric wheel 8 away from brake block 6, and can be by centrifugal 5 centrifugal triggering, so that the switching device that the eccentric part of eccentric wheel 8 is drawn close to brake block 6.
Described elastic tension apparatus is centrifugal the back-moving spring 13 last, that the other end is fixed on centrifugal wheel 2 circle centre positions that an end is fixed on centrifugal 5, and centrifugal 5 of this moment can be provided with, also can be the even numbered blocks setting for the odd number piece.
Centrifugal 5 of the four or four above even numbered blocks that evenly distribute on centrifugal wheel 2, described elastic tension apparatus is the back-moving spring 13 that is fixed on relative two centrifugal 5 centrifugal.
Described spring assembly is that an end is fixed on second bearing pin 7, the other end is fixed on the eccentric wheel 8, the middle part is wound on the torsion spring 9 on second bearing pin 7.
Described switching device is included in lever 10 hinged, that bend in obtuse angle on the installing plate 1, only revolve spring 11 near what be provided with tension between 10 1 sections bodies of rod of lever of eccentric wheel 8 and the installing plate 1, be convenient to be connected with that the one section lever 10 that only revolves spring 11 relies on and the torsion spring 9 of negative function on eccentric wheel 8 and the portion of only revolving 12 of only revolving spring 11 torsion being provided with on the eccentric wheel 8.
Described brake block 6 is fixedly installed on the installing plate 1 of pinch wheels 3 top positions, and eccentric wheel 6 is rotatably connected on the installing plate 1 of centrifugal wheel 8 tops by second bearing pin 7.
Eccentric wheel type centrifuge security lock of the present utility model is installed on the hanging basket by installing plate 1, wire rope 14 passes between centrifugal wheel 2 and the pinch wheels 3, between brake block 6 and the eccentric wheel 8, during operate as normal, along with hanging basket rises, eccentric wheel type centrifuge security lock of the present utility model is upwards slowly creeped on wire rope 14, and centrifugal wheel 2 slowly rotates clockwise.Along with hanging basket descends, eccentric wheel type centrifuge security lock of the present utility model is slowly creeped downwards on wire rope 14, and centrifugal wheel 2 slowly rotates counterclockwise.
When hanging basket when wire rope 14 descends fast, centrifugal wheel 2 clockwise rotates under the rubbing action of wire rope 14 fast, causing overcoming under action of centrifugal force for centrifugal 5 back-moving spring 13 pulling force throws away, bump lever 10, make eccentric wheel 8 under the twisting force of torsion spring 9, bounce back into application position from disengaged condition, clamp wire rope 14 with brake block 6, realize braking.
Braking of the present utility model is partly simple in structure, only is eccentric wheel 6, brake block 8 and torsion spring 9, and materials are few, low cost of manufacture; Safety rope and working rope unification are same wire rope 14, have changed each present situation with a rope of present safety rope and working rope (saving wire rope 1/2).Braking is reliable, because eccentric wheel 6 eccentric parts (active section) circular arc is longer relatively, and is not afraid of wearing and tearing.In case after the retaining segment wearing and tearing, after torsion spring 9 effects, turn over an angle automatically, can return to the braking impaction state again to next retaining segment locking.Therefore when eccentric wheel 6 braking contact surfaces simultaneously wear and tear since angle of rotation still compress, so braking is had the self-regulated restore funcitons; The sensing sensitivity: pinch wheels 3 and centrifugal wheel 2 slide fast at induction wire rope 14, and one hypervelocity takes place causes the centrifugal force brake activation.
