Wind power yaw brake HE-2-90/31 wind power brake

The present invention provides a wind power yao brake friction plate wear thickness detection device, meeting a brake cylinder body, where one side of the brake cylinder body is provided with a brake groove, And friction plates are movable on both upper and lower sides of the brake groove The end of the oil receiving groove away from the brake piston is connected to the oil discharge channel opened in the brake cylinder body, and the upper and lower friction plates include two independent friction plates arranged in parallel, The independent friction plate is driven by a telecommunication translation mechanism to perform translation motion along the axis of the brake disc The power mechanism operations under the control of a control device The present invention is not only monitoring the wear status of the friction plate in real time, But also independently replacing the friction plate after it coincidentally falls off or meets the replacement standard, and then replacing the falling or worn brake plate without timely intervention by humans, Greatly guaranteeing the yaw braking effect, events damage to the brake disc, and ensuring the normal operation of the fan
