摘要： An operation locking device for a climb-free system includes a locking assembly, a fixing block and a triggering assembly. The fixing block is mounted on a climb-free system trolley. The locking assembly is connected to the fixing block by the triggering assembly. The triggering assembly is configured to control the locking assembly to be switchable between a locked state and an unlocked state. When the climb-free system trolley is out-of-control, the triggering assembly triggers the locking assembly to switch to the locked state and to be clamped in a sliding rail, such that the climb-free system trolley stops operating. When the climb-free system trolley needs to adjust a working position by sliding up and down, the triggering assembly triggers the locking assembly to switch to the unlocked state and to be disengaged from the sliding rail.

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.

摘要： A cover plate assembly, a wind power tower tube, and a wind turbine. The cover plate assembly comprises: a drive component, comprising a swing rod (6) provided with a first limiting component (3); and a cover plate (8), suitable for rotating between a first position and a second position along with rotation of the swing rod (6), the cover plate (8) being provided with a guide component (4), and the guide component (4) moving along the swing rod (6) in a swinging process of the swing rod (6). At the second position, the guide component (4) is in limiting fit with the first limiting component (3), so as to limit the swing rod (6) to drive the cover plate (8) to move back towards the first position; and when the cover plate (8) rotates towards the second position, matching between the first limiting component (3) and the guide component (4) can prevent the cover plate (8) from continuing rotating.
