In figure 31 to figure 36,56 expression magnet stoppers, by retarding spring 54a, 54b, the braking bringing device that brake control lever 51a, 51b and brake plate 50a, 50b constitute is identical with above-mentioned the 7th embodiment, omits its explanation as required at this.

The end of spring bar 63a, 63b is supported on the brace table 81 of being located at matrix 21 tops by pivotal support pin 82, run through simultaneously this brace table 81 and brake control lever 51a, 51b the other end 51d from external parties towards the central side setting, retarding spring 54a, 54b are installed between described brake control lever 51a, 51b and spring bar 63a, 63b, and fixing by nut 66 and spring pressing member 67.Promptly, retarding spring 54a, 54b are arranged on the connection side that connects brake control lever 51a, another end of 51b 51d, from connecting the connection side of brake control lever 51a, another end of 51b 51d, this retarding spring 54a, 54b apply elastic force on respect to brake control lever 51a, the 51b direction for release, make brake plate 50a, 50b pushing brake surface 30C.

Calutron 55 adopts illustrated structure among the figure 13 to figure 15 of the 3rd embodiment basically.Promptly, described calutron 55 is arranged near another end 51d of described brake control lever 51a, 51b, be used to remove the thrust pressure of described retarding spring 54a, 54b, it is made of an electromagnet that is fixed 69, two movable iron 70a, 70b, take-off lever 84a, 84b and pressing plate 85a, 85b.Described electromagnet 69 directly or be arranged on the top of matrix 21 by brace table 83.In addition, described electromagnet 69 constitutes by two electromagnetism winding 72a, 72b and by these two shared yokes 73 of electromagnetism winding 72a, 72b, this yoke 73 has pole surface 74a, 74b at two places, be provided with electromagnetism winding 72a, 72b with respect to each pole surface 74a, 74b, described electromagnet 69 has the function of two electromagnet 69 in fact.Two movable iron 70a, 70b be configured to relative with this pole surface 74a, 74b to, these two movable iron 70a, 70b are connected with the end of take-off lever 84a, the 84b of the arranged outside of walking around electromagnet 69, the other end of this take-off lever 84a, 84b is connected with pressing plate 85a, 85b, makes the action of movable iron 70a, 70b output to movable iron 70b, the 70a side of opposition side respectively.But 86 expressions are supported on counter-rotative type revolving bar on the brace table 81 by pivotal support pin 86a in rotatable mode, and one end thereof is threaded with contact lever 87 and is fixed by retaining nut 88, and contact lever 87 is connected with described pressing plate 85a, 85b.Another end of this revolving bar 86 connects another end 51d of described brake control lever 51a, 51b.That is, pressing plate 85a, 85b are connected to drive with another end 51d of described brake control lever 51a, 51b by revolving bar 86 respectively.

89 expressions keep springs, are used to prevent to connect bar 84a, the 84b skew of movable iron 70a, 70b, its be installed in and brace table 83 between.The strut bar of described brace table is located in 90 expressions, and described movable iron 70a, 70b are slidably supported by this strut bar 90.Described electromagnet 69 energising backs produce magnetic flux, and electromagnetic attraction acts on described movable iron 70a, the 70b, thereby movable iron 70a, 70b are held.By take-off lever 84a, 84b, pressing plate 85a, 85b and swivel mount 86, another end 51d of described brake control lever 51a, 51b is driven.That is, in described calutron 55, the electromagnetic attraction of described electromagnet 69 is exported on the direction of closure for release with respect to another end 51d that connects brake control lever 51a, 51b.

The adjusting of the elastic force of retarding spring 54a, 54b is carried out with the amount of deflection of regulating retarding spring 54a, 54b by swivel nut 66.And, by regulating the length of contact lever 87, not only can regulate the stroke between movable iron 70a, 70b and the electromagnet 69, but also can regulate the stroke between brake plate 50a, 50b and the brake surface 30c.

That is to say, braking applying mechanism via brake plate 50a, 50b and brake control lever 51a, 51b and retarding spring 54a, 54b formation has two groups, these two groups braking applying mechanisms are corresponding with the braking cancel system that is made of electromagnet 69 and movable iron 70a, 70b respectively, thereby constitute two groups of stop mechanisms that can play a role separately as magnet stopper 56.

Used and had as mentioned above the Winch for elevator of the calutron of structure and can obtain and the identical effect of above-mentioned the 7th embodiment.

And, in the above description, the electromagnet 69 with two electromagnetism winding 72a, 72b of calutron 55 is configured to fix, iron plate 70a, 70b are configured to movably, but also can as the figure 19 of above-mentioned the 3rd embodiment is illustrated, two electromagnetism winding 72a, 72b be merged into an electromagnetism winding.

And, shown in the figure 15 of above-mentioned the 3rd embodiment, in the figure 31 to figure 36 of the 8th embodiment, also can be with the movable of movable iron 70a, 70b and electromagnet 69 and fixed form exchange, two movable iron 70a, 70b are merged into one and set for fixing, and an electromagnet 69 is divided into two and set for movably, the electromagnetism winding is set respectively then.

Figure 37 to figure 38 expression ninth embodiment of the invention, figure 37 is the front elevation with elevator hoist of the related outer peripheral face brake type magnet stopper of present embodiment, suitable with the figure 27 of above-mentioned the 7th embodiment, figure 38 is B-B line section-drawings of figure 37, suitable with the figure 28 of above-mentioned the 7th embodiment, and the part identical with figure 27 and figure 28 adopts prosign to represent, omits its explanation at this as required.
