Description
Technical field
The present invention relates to capstan winch, it is a kind of electronic two speed capstan winch and method of work thereof.
Background technology
Power capstan is a kind of device that can be used for traction, such as automobile winch, is used in severe environment and saves oneself and sue and labour. Existing power capstan is primarily of structure compositions such as motor, transmission shaft, speed reducing transmission case, winding drums, rely on the power that speed reducing transmission case is connected between motor and winding drum, make the wireline being wrapped on winding drum can produce bigger tractive force, it is achieved capstan winch traction function. Power capstan, except traction function, is often provided with engaging and disengaging gear in speed reducing transmission case, is connected for the power cut off between motor with winding drum, thus facilitate wireline on winding drum pull operation. Therefore existing power capstan is mostly the capstan winch of single speed band clutch for clutch control, but this kind of single speed capstan winch scope of application is comparatively limited, the more difficult operation being applicable to many speed traction working conditions. For this reason, prior art again discloses some power capstans with speed-regulating function, but existing speed governing is mostly realized by the speed governing gear of different chi ratio, complex structure is not only installed, volume is relatively big, and operation is comparatively required great effort, therefore needs to be improved by existing speed governing capstan winch.
Summary of the invention
For overcoming above-mentioned deficiency, it is an object of the invention to provide a kind of electronic two speed capstan winch and method of work thereof to this area so that it is solve existing similar capstan winch structure comparatively complicated, the technical problem that speed governing is comparatively inconvenient.
