摘要： The present application relates to the technical field of linkage mechanisms, and provides a linkage operation assembly, a fall protection device and a fall protection system. The linkage operation assembly includes a fixed main body configured to be installed on an outer support surface of a rail and move along the rail; a second wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a second wheel set and a drive rotary shaft; a third wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a third wheel set and a driven rotary shaft; and a linkage member disposed between the drive rotary shaft and the driven rotary shaft. When the drive rotary shaft of the linkage operating assembly rotates, the second wheel set is driven to rotate, and the driven rotary shaft and the third wheel set are driven to rotate through the linkage member. Therefore, during the installation process of the linkage operation assembly, only the drive rotary shaft needs to be rotated to switch the state of the linkage operation assembly, so as to facilitate the installation of the linkage operation assembly. Similarly, when the linkage operation assembly is disassembled, only the drive rotary shaft needs to be rotated.

摘要： The present application relates to the technical field of aerial climbing and transportation operations, and provides a fall protection locking assembly, a fall protection device and a fall protection system. The fall protection locking assembly includes a fixed main body, configured to be installed to a rail through a first wheel body assembly containing a wheel shaft; a lockup member installed on the fixed main body and be switched between a lockup position and a free position; and a first trigger mechanism installed to the fixed main body, the first trigger mechanism includes a transmission member and a drive member, the transmission member is configured to be installed to the wheel shaft and rotate with the wheel shaft, and the transmission member is switched with changes in centrifugal force between a first position, in which the transmission member is disengaged from the drive member in the first position, and a second position, in which the transmission member transmits the rotation of the wheel shaft to the drive member so that the drive member rotates to drive the lockup member to move to the lockup position. When an operator accidentally falls, a wheel shaft will have a higher rotational speed, and then a transmission member will drive the drive member to move together under the action of centrifugal force, thereby driving the lockup member moves to the lockup position to ensure the safety of use.
