Embodiment Construction

[0023] Below, refer to Figure 1-7 Embodiments of an electromagnetic brake release device and an elevator will be described. In addition, the same code|symbol is attached|subjected to the common member in each figure.

[0024] 1. Example of implementation

[0025] 1-1. The structure of the elevator

[0026] First, refer to figure 1 The structure of the elevator which concerns on embodiment (henceforth "this example") is demonstrated.

[0027] figure 1 It is a schematic configuration diagram showing a configuration example of the elevator of this example.

[0028] Such as figure 1 As shown, the elevator 1 of this example is installed in an elevator shaft 110 formed in a building structure. The elevator 1 includes: a car 120 for lifting and lowering in an elevator shaft 110 and carrying people or goods; a rope 130 ; a counterweight 140 ; ​​and a traction machine 100 . At the top of the elevator shaft 110 there is a machine room 160 .

[0029] The hoisting machine 100 is...

Abstract

To provide an electromagnetic brake release device capable of releasing a plurality of electromagnetic brake devices simultaneously and an elevator.SOLUTION: An electromagnetic brake release device 50A includes a first brake release mechanism 51A, a second brake release mechanism 51B, an operation lever 56, and a transmission mechanism 52. The first brake release mechanism releases braking in a first electromagnetic brake device 10A. The second brake release mechanism releases braking in a second electromagnetic brake device 10B. The operation lever 56 is mounted on the first brake release mechanism 51A so as to perform rotating operation with respect to the first brake release mechanism 51A. The transmission mechanism 52 transmits torque generated when performing the rotating operation of the operation lever 56 to the second brake release mechanism 51B from the first brake release mechanism 51A.SELECTED DRAWING: Figure 3

Description

technical field [0001] The present invention relates to an electromagnetic brake release device that releases an electromagnetic brake device that brakes a hoisting machine, and an elevator including the electromagnetic brake release device. Background technique [0002] Currently, an elevator includes a car, a counterweight, a rope connecting the car and the counterweight, and a traction machine around which the rope is wound. The traction machine has: a driving unit; a rotating shaft connected to the driving unit; a traction sheave around which a rope is wound and supported by the rotating shaft so as to be rotatable; and a brake disc connected to the traction sheave. In addition, the hoisting machine is provided with an electromagnetic brake device that brakes the sheave by braking the rotation of the brake disc. [0003] In addition, when the car stops suddenly due to an emergency such as a power outage or an earthquake, the car may stop at a stop position different fro...
