In addition, the second hook spare 27 and the 3rd hook spare 28 are provided with the bolt 30 of clamping the first hook spare 26 from two ends, 30A.And governor 6 possesses wedge portion 31,31A, as wedge portion 31, the axle 32 of the pivot point of 31A, the 32A and the second hook spare 27 and the 3rd hook spare 28 cards pin 33 thereon, 33A.Wedge portion 31 is provided with pin 34,34A on the 31A.Bar 35,35A are mounted to can be around the pin 36 that is fixed on the framework 11A (with reference to figure three), and 36A freely rotates, and when elevator normally moves, relies on deadweight, and moment loading is in graphic direction.
And, on governor 6, be provided with holding piece 37,37A and cover plate 38,38A, holding piece 37,37A and cover plate 38 are provided with pad 39,39A between the 38A.
Be provided with spring bracket 40,41,42 between wedge portion 31 and the 31A of wedge portion, be provided with a plurality of disk springs 43 between the spring bracket 41,42.And shown in figure two, 8 disk springs are arranged alternately.On the spring bracket 41,42 screw thread is arranged,, can change the amount of compression of disk spring 43, so can regulate the spring force of disk spring 43 by turn spring bracket 41.
The first hook spare 26, the second hook spare 27, the 3rd hook spare 28 and wedge portion 31 constitute the shape shown in the figure three around the 31A.Bar 35,35A and pin 36,36A can not come off under the effect of 44A at snap close ring 44. Brake component 45,45A are used for limiting lever 35, the rotating range of 35A.
Below describe with regard to the action of governor 6.Figure four expression lift cars 1 are in the ascent direction hypervelocity, make governor pulley 13 exceed the speed limit in the counterclockwise direction and situation when reaching switch and turn-offing action, the further aggravation and reach the situation of holding action with clamping governor rope 7 of figure five expression hypervelocities.
At first, shown in figure four, by the centnifugal force that the rotation by governor pulley 13 produces, tilting member 18, the 18A swing, tilting member 18, the claw 46 of 18A front end, 46A moves towards the outside diameter of governor pulley 13.And, under the situation of the speed that reaches regulation, claw 46,46A contacts with switch plate 23, towards the anticlockwise direction rotation it is fallen down by making the snap-latch piece that is made of this switch plate 23 and switch cam, and switch 22 becomes disarm state.At this moment, because the first hook spare 26 does not also have and claw 46, the 46A contact is so the first hook spare 26 is still kept handstand state.
Exceed the speed limit further aggravation and cause tilting member 18,18A further swings, claw 46, after 46A further moves towards the outside diameter of governor pulley 13, shown in figure five, claw 46,46A contacts with the first hook spare 26, is rotated in a clockwise direction thereby the first hook spare 26 is fallen down and make it center on axle 25.The first hook spare 26 makes the second hook spare 27 around axle 25 rotation in the counterclockwise direction by bolt 30A, thus combining between the second hook spare 27 and the pin 33 be disengaged, thereby the support of wedge portion 31 is disengaged.Wedge portion 31 relies on deadweight, while fall to rotating in the counterclockwise direction around axle 32, and this wedge portion with relative to holding piece 37 between clamping governor rope 7.At this moment, axle 32 moves towards right shown in figure five, so pass through the elastic force of disk spring 43, pushes wedge portion 31 to governor rope 7, and governor rope 7 is clamped between wedge portion 31 and the holding piece 37.The Clamping force of this moment is by the elastic force and the decision of the friction characteristics between governor rope 7 contact parts (wedge portion 31 and holding piece 37) of disk spring 43.In addition, when wedge portion 31 fell, it was that rotate in the counterclockwise direction at the center with pin 36 that pin 34 makes bar 35.Its result, bar 35 becomes the state shown in the figure five, and is positioned at the position of supporting the first hook spare, 26 bottoms.
So,, compare, can dwindle the clamp structure of governor rope 7 with using helical spring occasion by using disk spring 43.And, because in wedge portion 31, be provided with disk spring 43 between the 31A, and one of disk spring 43 is distolaterally supported by a wedge portion 31, another of disk spring 43 is distolateral to be supported by the 31A of another wedge portion, so can obtain Clamping force from shared disk spring 43 respectively, keep structure thereby can simplify the governor rope, realize the miniaturization of governor 6.Therefore, not only when the overspeed condition of descent direction appears in lift car 1, and when the overspeed condition of ascent direction appears in lift car 1, also can clamping governor rope 7, even, still can realize miniaturization on the whole so this dish-type governor is provided with two wedge portions.
In the present invention, when falling in wedge portion 31, shown in figure five, pin 34 makes bar 35 fall down towards anticlockwise direction, so when the first hook spare 26 is fallen down toward the clockwise direction, also played the effect that the support stick as the first hook spare 26 uses.Thus, switch cam 24 is from pin 29 landings, thus switch 22 is disconnected, and, only otherwise, switch 22 is resetted manually the first hook spare 26, the second hook spare 27 and wedge portion 31 are returned to original state.So, when wedge portion 31 fell, therefore the off-state of maintained switch 22 can realize safe elevator device reliably.
In addition, occur hypervelocity even lift car 1 occurs at ascent direction, the situation of hypervelocity appears in governor pulley 13 in the clockwise direction, as long as governor pulley 13 reaches predetermined rotational speed, switch will disconnect action.When the hypervelocity of lift car 1 is further aggravated, carry out holding action, governor rope 7 is clamped between 31A of wedge portion and the holding piece 37A.So, when lift car 1 when overspeed condition appears in descent direction, by one of them wedge portion 31 clamping governor rope 7, and when lift car 1 when overspeed condition appears in ascent direction, by another 31A of wedge portion clamping governor rope 7.
