Title:
BRAKE SHOE ATTITUDE CONFIRMATION DEVICE, ELECTROMAGNETIC BRAKE DEVICE FOR ELEVATOR HOISTING MACHINE EQUIPPED WITH THE SAME, AND BRAKE SHOE ATTITUDE CONFIRMATION METHOD
Document Type and Number:
Japanese Patent JP2013160304
Kind Code:
A
Abstract:

To provide a brake shoe attitude confirmation device etc. that can confirm the attitude change of a brake shoe.

A brake shoe attitude confirmation device 51 includes a first diagonal distortion gauge 55, a second diagonal distortion gauge 57, a thin film member 61, an information transmission means 59, and an arithmetic processing part 53. The information transmission means transmits the output values of the first and second diagonal distortion gauges to the arithmetic processing part, and the thin film member is provided to bridge a field 11 and a brake shoe 7 of a brake device. The first and second diagonal distortion gauges are provided on the thin film member along two imaginary lines on the surface of the thin film member. The two imaginary lines incline with respect to the operating direction of the brake shoe and intersect each other. The arithmetic processing part computes a difference between the output values of the first and second diagonal distortion gauges to confirm the attitude of the brake shoe.
