A safety device for lifting equipment of wind turbine tower guide rail

Abstract

This utility model relates to a safety device for a wind turbine tower guide rail lifting device. It includes a mounting frame assembly, on which are mounted an overspeed triggering component, a speed measuring and clamping component, and a fall triggering component. The fall triggering component includes a secondary locking tongue and a secondary locking tongue spring. The overspeed triggering component includes a centrifugal throwing mechanism, a speed measuring wheel, and a main locking tongue, with a main locking tongue spring connecting the main locking tongue and the mounting frame assembly. The speed measuring and clamping component includes two clamping swing arms rotatably connected to the centrifugal throwing mechanism, each clamping swing arm being pivotally connected to the fall triggering component and the mounting frame assembly. The middle portion of each clamping swing arm is inserted into and movably connected to a clamping groove on the end face of the main locking tongue. It also includes an adjusting elastic mechanism installed between the clamping swing arms and the mounting frame assembly. This utility model can be triggered and activated under both fall and overspeed conditions, ensuring that the speed measuring wheel always abuts against the guide rail and runs along the guide rail, preventing speed measuring wheel failure.
