Abstract

The invention relates to the field of hoisting machinery, in particular to an electric hoist and a wind driven generator. The electric hoist comprises a shell, a main shaft, a friction component and acentrifugal component, wherein the main shaft is mounted on the shell and can rotate relative to the shell, the main shaft is fixedly connected with the friction component, and the centrifugal component is arranged on the friction component. When the rotating speed of the main shaft exceeds a preset speed, the centrifugal component can extend out of the friction component under the action of centrifugal force and rubs with and abuts against the inner wall of the shell so as to limit the rotating speed of the main shaft. When the rotating speed of the main shaft does not exceed the preset speed, the centrifugal component is not in contact with the inner wall of the shell, and the main shaft is kept to rotate at the speed not higher than the preset speed. The electric hoist can be used forhigh-altitude escape.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to an electric hoist and a wind power generator. Background technique [0002] Wind power generators in the related art are usually equipped with corresponding electric hoists to facilitate lifting heavy objects, etc.; however, the electric hoists provided in the related art are difficult to be used for high-altitude escape by workers working at heights. Contents of the invention [0003] Objects of the present invention include, for example, providing an electric hoist and a wind generator, which can be used for escape from heights. [0004] Embodiments of the present invention can be realized like this: [0005] In the first aspect, an embodiment of the present invention provides an electric hoist, including a housing, a main shaft, a friction assembly, and a centrifugal assembly. The main shaft is installed in the housing and can rotate relative to the housing. Friction asse...
