Definitions
- the present invention relates to a brake device for an elevator hoist.
- an elevator hoisting brake device using an electromagnetic magnet energizes an electromagnetic coil attached to a fixed iron core when the brake is released, attracts the movable iron core, and releases the brake drum force. Also, when the brake is dropped, by stopping energization to the electromagnetic coil, the brake shoe interlocked with the movable iron core is pressed against the brake drum by the spring inside the fixed iron core, and the brake is applied (see Patent Document 1, for example).
- the armature which is a movable iron core, is configured to be supported by a guide rod with a spherical bearing (see, for example, Patent Document 2).
- Patent Document 1 Japanese Unexamined Patent Publication No. 2005-178969

- a fixed iron core and a movable iron core that is placed opposite to the suction surfaces on both sides of the fixed iron core, urged in the direction of the brake drum by an urging spring, and attracted to the fixed iron core by the electromagnetic force of the electromagnetic coil.
- a brake device of an elevator hoisting machine provided with a brake shoe provided on an iron core and facing a brake drum, a suction surface of a fixed iron core and a movable iron core facing the suction surface are provided.
- Each is provided with engagement means that engage with each other and enable the movable iron core to move in the direction of the rotation axis of the brake drum while supporting its own weight on the fixed iron core. .
- the engaging means includes a concave portion provided in the fixed iron core and a convex force provided in the movable iron core and fitted to the concave portion. It is.
- the engaging means includes a key groove provided to face the fixed iron core and the movable iron core, and a key fitted in the key groove. It ’s a life.
- the elevator hoisting machine brake device is provided with a jig hole for attaching and detaching the movable iron core at a position where the magnetic field is not affected by the movable iron core.
- FIG. 1 is a front view showing a brake device for an elevator hoisting machine according to Embodiment 1 of the present invention.
- FIG. 2 is a front view showing a brake device for an elevator hoisting machine according to Embodiment 2 of the present invention.
- FIG. 3 is a front view showing a brake device for an elevator hoisting machine according to Embodiment 3 of the present invention. .
- drum brake device of an elevator hoisting machine will be described as an example.

- the brake drum 1 can move in the direction of the rotation axis while being supported by the iron core 2.
- the concave portions 6 are provided on both sides of the fixed iron core 2, and the pair of movable iron cores 4 are provided with the convex portions 7 that fit the concave portions 6.
- the pair of movable iron cores 4 are supported on both sides of the fixed iron core 2 without free-falling as in the prior art without the elastic support of the spring receiver 4a.
- the worker can receive the spring without causing the weight of the pair of movable iron cores 4 to be a problem.
- FIG. 2 is a front view showing a brake device for an elevator hoisting machine according to Embodiment 2 of the present invention.
- the same reference numerals are used for the corresponding parts of the first embodiment, and the description thereof is omitted.
- the overlapping of the pair of movable iron cores 4 by the engaged recesses 6 and the protrusions 7 is performed.
