Below referring to figs. 1 through Figure 25 embodiments of the present invention are described.Fig. 1 is the front view of the Winch for elevator of the present invention's the 1st embodiment, Fig. 2 and Fig. 3 are about in the birds-eye view of Fig. 1 magnet stopper being arranged on instruction diagram in the specialized range with planar dimension, Fig. 4 and Fig. 5 are respectively front view and the lateral plans that links the connect mechanism of main brake arm and secondary brake control lever, Fig. 6 and Fig. 7 are respectively the front view and the lateral plans of the general configuration of the winch of Fig. 1 elevator that is arranged on the bottom in the hoist trunk, Fig. 8 is that the winch of presentation graphs 1 revolves the figure that turn 90 degrees the winch when being provided with, Fig. 9 is equivalent to Fig. 6, the winch of presentation graphs 8 is arranged on the figure of general configuration of the elevator on the top in the hoist trunk, and Figure 10 to Figure 25 is the figure of other embodiments of expression connect mechanism.
The electrical motor 1 of Fig. 1 is an outside rotary-type motor.The stator 3 of pedestal 2 supporting motors 1 of electrical motor 1, and by axle supporting rotors 4 such as projecting shafts, and rotor 4 can be rotated.Rotor 4 has flat shape, and its axial size diameter group is little.From the winch that comprises pedestal 2 on the whole, the axial dimension of rotor 4 is littler than the diametric size of rotor, so this winch is slim winch.In electrical motor 1, stator 3 is positioned at the inside of rotor 4, and opposed with rotor 4.Rotor 4 is the bodies that are braked of this electrical motor 1, and the outer peripheral face of rotor 4 is used as brake surface 5 uses.Rope sheave 6 is arranged on the side of rotor 4, and with rotor 4 coaxial settings, its both sides are wound with the hoist cable 9 of engaging lift car 7 and counterbalanced weight 8. Magnet stopper 10a, 10b are separately positioned on the upper and lower of rotor 4, have independently braking function separately respectively, and rotor 4 is braked.Winch 11 is made of pedestal 2, electrical motor 1, rope sheave 6 and magnet stopper 10a, 10b, and pedestal 2 is arranged in the hoist trunk as mounting base.
Secondary brake control lever 20a, 20b and main brake arm 12a, 12b configured in parallel, and by axle 21a, 21b rotating support, link by connect mechanism 22a, 22b and each main brake arm 12a, 12b.In secondary brake control lever 20a, 20b, be identical direction rather than opposite direction with direction of action as the point of action of the point of contact of connect mechanism 22a, 22b as the point of application of the drive point of electromagnetic mechanism described later.
The spring force that electromagnetic mechanism 23a, 23b overcome the retarding spring 15a, the 15b that push main brake arm 12a, 12b drives each secondary brake control lever 20a, 20b respectively to the press direction shown in the arrow Y1, drive main brake arm 12a, 12b by connect mechanism 22a, 22b and come pushing of brake off sheet 13a, 13b, remove braking thus rotor 4.
In the magnet stopper 10a of upside, under the effect of the weight that the movable part of main brake arm and secondary brake control lever 12a, 20a, brake plate 13a, retarding spring 15a, connect mechanism 22a and electromagnetic mechanism 23a grades, increase braking pressing force to rotor 4.In the same manner, in the magnet stopper 10b of downside, under the effect of the weight that the movable part of main brake arm and secondary brake control lever 12b, 20b, brake plate 13b, retarding spring 15b, connect mechanism 22b and electromagnetic mechanism 23b grades, the braking pressing force reduces.In order to relax the increase and decrease phenomenon of this pressing force, be provided with the pressing force correction mechanism that pressing force is revised.
Be to revise the braking pressing force of main brake arm 12a, 12b specifically by comprising pressing force correction mechanism 33a, the 33b of spring device 32a, 32b.Thus, the pressing force of the increase of brake plate 13a, the 13b of the moment generation relevant with axle 14a, 14b or the pressing force that reduces obtain counteracting under the influence of main brake arm 12a, 12b, brake plate 13a, 13b, retarding spring 15a, 15b and weight such as connect mechanism 22a, 22b.As shown in Figure 1, in the center of gravity Gma of main brake arm 12a, 12b, the same side of Gmb, make this main brake arm 12a, 12b on the direction that direction is mentioned shown in the arrow Ym, apply spring force with respect to axle 14a, 14b by spring device 32a, 32b.As the installation constitution of spring device 32a, 32b, for example adopt the structure identical with retarding spring 15a, 15b.In addition, though the diagram of omission, but also spring device 32a, 32b can be arranged at the opposition side of center of gravity Gma, the Gmb of main brake arm 12a, 12b main brake arm 12a, 12b further be prolonged with respect to axle 14a, 14b, on the direction of pushing downwards by spring device 32a, 32b spring force is applied on this prolongation, perhaps only applies quality so that revise by weight.
Equally, by comprising that pressing force correction mechanism 35a, the 35b of spring device 34a, 34b revise the braking pressing force of secondary brake control lever 20a, 20b.Thus, the power that the moment relevant with axle 21a, 21b produces under the influence of the weight that the movable part of secondary brake control lever 20a, 20b, electromagnetic mechanism 23a, 23b grades is delivered to the pressing force of increase of brake plate 13a, 13b or the pressing force that reduces is cancelled via connect mechanism 22a, 22b.In Fig. 1, in the center of gravity Gsa of brake control lever, the same side of Gsb, make this pair brake control lever 20a, 20b on the direction that the direction shown in the arrow Ys is mentioned, apply spring force by spring device 34a, 34b with respect to axle 21a, 21b.In addition, though the diagram of omission, but also spring device 34a, 34b can be arranged at the opposition side of center of gravity Gsa, the Gsb of secondary brake control lever 20a, 20b secondary brake control lever 20a, 20b further be prolonged with respect to axle 21a, 21b, on the direction of pushing downwards by spring device 34a, 34b spring force is applied on this prolongation, perhaps only applies quality so that revise by weight.
Thus, revise by spring device 34a, 34b, make not and can produce the braking pressing force because of the weight of the attached member of main brake arm 12a, the 12b of the upside of Fig. 1 and downside and secondary brake control lever 20a, 20b, can overbalance not appear because of the braking pressing force of upside and downside, by retarding spring 15a, 15b, can apply the braking pressing force of regulation according to the roughly the same spring force that sets at upside and downside.
As mentioned above, in the explanation of the embodiment of Fig. 1, when supposing that gravity direction is vertical, main brake arm 12a, 12b and secondary brake control lever 20a, the length direction of 20b is horizontal, thus, at main brake arm 12a, 12b and secondary brake control lever 20a, under the influence of the weight of the attached member of 20b, the braking pressing force of the brake plate 13a of upside can increase, and the braking pressing force of the brake plate 13b of downside can reduce, and at this magnet stopper 10a, 10b is configured to main brake arm 12a, 12b and secondary brake control lever 20a, when the length direction of 20b and gravity direction constitute arbitrarily angle, the braking pressing force that causes at weight because of attached member, only need to because of this arbitrarily the component on the gravity direction that produces of angle make consideration.For example, when the length direction of brake control lever disposes along gravity direction is promptly vertical, because angle is 0, so the weight of main brake arm 12a, 12b and attached members such as secondary brake control lever 20a, 20b can not produce the component that does not act on the braking pressing force basically.
