The invention relates to the technical field of fans, and provides a cover plate assembly of a climbing-free device and the climbing-free device. The cover plate assembly comprises a cover plate, a fixing plate, a motor and a rotating assembly connected with the motor, wherein the cover plate is rotationally arranged on a platform of a tower cylinder, a traction piece is wound around the rotatingassembly, the free end of the traction piece is connected with the cover plate, and the rotating assembly is provided with a trigger plate; the fixing plate is arranged on the side, back on to the motor, of the rotating assembly, the fixing plate is provided with a first limiting switch and a second limiting switch which are electrically connected with the motor, the first limiting switch and thesecond limiting switch are positioned on the rotating stroke of the trigger plate, and the relative positions of the first limiting switch and the second limiting switch meet the following conditionsthat when the cover plate opens a lifting vehicle channel of the platform, the trigger plate triggers the first limiting switch; and when the cover plate closes the lifting vehicle channel of the platform, the trigger plate triggers the second limiting switch. According to the cover plate assembly of the climbing-free device and the climbing-free device, for cover plates with different specifications and sizes, the mounting positions of the first limiting switch and the second limiting switch on the fixing plate do not need to be adjusted in the field mounting process.
本发明涉及风机技术领域,提供了一种免爬器的盖板组件和免爬器。该盖板组件包括盖板、固定板、电机、与电机连接的转动组件,盖板可转动地设置在塔筒的平台上,转动组件绕设有牵引件,牵引件的自由端与盖板连接,转动组件设置有触发板;固定板设于转动组件背向电机的一侧,固定板设有与电机电连接的第一限位开关和第二限位开关,第一限位开关和第二限位开关位于触发板的转动行程上,第一限位开关和第二限位开关的相对位置满足:当盖板打开平台的升降车通道时,触发板触发第一限位开关;当盖板关闭平台的升降车通道时,触发板触发第二限位开关。本发明针对不同规格尺寸的盖板,现场安装无需调节第一限位开关和第二限位开关在固定板上的安装位置。
