Description

Technical Field

[0001] This utility model belongs to the field of blade processing technology, and more specifically, it relates to a flipping device for wind turbine blade processing. Background Technology

[0002] Currently, Chinese patent CN216229265U discloses a flipping device for wind turbine blade processing, belonging to the technical field of wind turbine blade auxiliary devices. It includes a power output device, a track, and a support flipping device. The power output device comprises a motor, a support plate, and a flange. The motor has an output shaft that passes through the center of the support plate. A set of triangular support frames is provided on the bottom frame, fixedly connected to a fixed block. The fixed block is fixedly connected to a bearing, and the bearing is connected to a fixed rod. The fixed rod has a through hole. The clamping device includes a set of sleeve rods, a set of telescopic rods, a set of clamping members, and a set of clamping plates. A compression spring is provided inside the sleeve rods and fixedly connected to the telescopic rods. The telescopic rods are fixedly connected to the clamping members. A sliding rod is provided inside the clamping member. A connecting rod is provided on the bushing and connected to the clamping plate. A slide rail is provided on the clamping member. This solves the problem that wind turbine blades can only be flipped using hoisting machinery for processing different positions, and is mainly used in wind turbine blade applications.

[0003] While this device can rotate and position blade workpieces, it suffers from several drawbacks: low clamping flexibility, inability to adjust position according to actual operating conditions, and inability to clamp blade workpieces of different lengths (it only performs single clamping and positioning), resulting in poor clamping stability. Although rotation is possible, the lack of synchronous rotation mechanisms at both ends can easily lead to asynchrony during rotation, causing blade vibration and deformation, posing a potential operational hazard. Furthermore, the device lacks safety protection structures; during blade rotation, interference from objects can easily damage the blades, potentially causing serious injury to personnel. This lack of safety considerations significantly reduces operational safety. Utility Model Content
