Title:
MAGNETORHEOLOGICAL EFFECT-BASED SMART VERTICAL SHAFT BRAKING AND BUFFERING SYSTEM, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/210885
Kind Code:
A1
Abstract:
A magnetorheological effect-based smart vertical shaft braking and buffering system, and an application thereof, said system comprising a retarder, a buffer (2), a rotational speed sensor (13), a pressure sensor (6), photoelectric switches (7) and a controller. The retarder is in a transmission connection between a lifting motor (8) and a lifting machine drum (1), the buffer (2) is mounted on a box beam (4) within a vertical shaft and connected to a cage support apparatus (3), the rotational speed sensor (13) is mounted on the lifting machine drum (1), the pressure sensor (6) is mounted at the bottom of a cage (5), the photoelectric switches (7) are mounted on a side wall of the vertical shaft, and the retarder, the buffer (2), the rotational speed sensor (13), the pressure sensor (6) and the photoelectric switches (7) are respectively connected to the controller. The braking and buffering system is smart, and can adjust the damping force of the retarder and the buffer (2) in a timely manner according to the speed, weight and position information of the cage (5), so that the buffer (2) has a flexible buffering effect on the cage (5), thereby preventing personnel or materials from being damaged due to impacts, and preventing over-winding, over-releasing and excessive speed accidents caused by personnel operational errors.
