Title:
FALL PREVENTION LOCKING ASSEMBLY, FALL PREVENTION DEVICE, AND FALL PREVENTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/051803
Kind Code:
A1
Abstract:
The present invention relates to the technical field of high-altitude climbing and transportation operations, and provides a fall prevention locking assembly, a fall prevention device, and a fall prevention system. The fall prevention locking assembly comprises: a fixed body mounted to a rail by means of a first wheel body assembly comprising a wheel shaft; a locking member mounted in the fixed boy and switching between a locking position and a free position; and a first trigger mechanism mounted in the fixed body and comprising a transmission member and a drive member, wherein the transmission member is used for mounting to the wheel shaft and rotating with same, and switches between a first position and a second position as the centrifugal force changes; the transmission member is detached from the drive member at the first position; the transmission member transfers the rotation of the wheel shaft to the drive member at the second position; the drive member rotates and drives the locking member to move to the locking position. When an operator falls by accident, the wheel shaft has a high rotational speed, and thus the transmission member drives the drive member under the function of the centrifugal force to move together to drive the locking member to move to the locking position to ensure the use security.
