Title:
MONORAIL CRANE BRAKE SHOE LOST MOTION TIME DETECTION DEVICE AND DETECTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/206933
Kind Code:
A1
Abstract:
A monorail crane brake shoe lost motion time detection device and a detection method thereof. The detection device comprises a contact detection unit (1), a common end roller unit (2), a lost motion time detection unit (3) and a detection line (4). The contact detection unit (1) is mounted on a brake (5) of a monorail crane; the common end roller unit (2) is mounted on a frame (8) of the monorail crane and corresponds to a driving rail (7); the contact detection unit (1) comprises a barrel (101) connected to the brake (5); a metal probe (102) corresponding to the driving rail (7) is provided in the barrel (101); a protruding cylindrical block is formed on the metal probe (102); a limiting bolt (108) corresponding to the protruding cylindrical block is formed on the inner side wall of the barrel (101); the metal probe (102) comes into contact with the driving rail (7) or the limiting bolt (108) when the brake (5) implements braking; the lost motion time detection unit (3) is electrically connected to the metal probe (102), the limiting bolt (108) and an axle (202) of the common end roller unit (2) by means of the detection line (4). The device can solve the problems of large measurement error, low adaptability and easy interference in a conventional method.
