Abstract

PURPOSE:To improve reliability and safety by moving axially bolts normally provided as a means of releasing the braking condition of an electromagnetic brake in the electromagnetic brake and releasing the brake in the position of the moved bolt as a fulcrum with a general tool inserted in the opposite side. CONSTITUTION:Bolts A26, B27 are provided in a disk on the outer peripheral part of a lining 6 to be axially moved. The bolts A26, B27 are moved toward an armature 4 which is moved toward a core 10 to adhere to the core 10. Under such a condition, the lining 6 is under the incompletely released condition. Then, a releasing member 28 is inserted in a gap between the armature 4 and disk 3 at a fulcrum O position approximately point-symmetrical about a rotary shaft 1 relative to the positions of provided bolts A26, B27, so that the armature 4 is moved to the core side by utilizing the principle of leverage to release completely the lining 6. Thus, braking is easily released by substituting the releasing member by a driver or the like to improve the maintenance property and safety.

In the above prior art, the shape of the release lever 20 is 4. Since the U-shape must be formed to match the outer diameter of the core 10, it is a tool exclusively used for electromagnetic brakes. Therefore, when used as an electromagnetic brake for an elevator hoist, it must be kept in the elevator machine room or
Maintenance personnel must bring it with them when performing maintenance. In an emergency situation, such as when a passenger is trapped in a car in an elevator where the release lever 20 is not always available, a situation may arise in which the electromagnetic brake must be released as soon as possible to rescue the passenger. However, there was also the problem that emergency measures could not be taken. Further, as described above, the release lever has a U-shape with an outer diameter that matches the core, etc., and therefore is not suitable for maintenance personnel to carry, so portability has not been considered.
