The invention provides a portable electric capstan which comprises an electric motor (1) and a winding drum (2), the electric motor (1) is used for driving the winding drum (2) to rotate, a pulling rope (3) is wound on the winding drum (2), one end of a rotating shaft (25) of the electric motor (1) is connected with an electromagnetic brake structure (6), the other end of the rotating shaft (25) is connected with a gear speed reduction structure (7), and the output end of the gear speed reduction structure (7) is connected with the winding drum (2); the gear speed reduction structure (7) and the electromagnetic brake structure (6) serve as components of a brake scheme at the same time, when the electric motor (1) is powered off and stops traction, the gear speed reduction structure (7) provides speed reduction resistance through the speed reduction ratio, and the electromagnetic coil (8) is powered off at the same time so that the elastic piece (12) can press the static disc (9) against the movable disc (10) again to brake the movable disc (10). The braking scheme of the electric capstan is high in reliability and convenient to use.
本公开提供了一种便携式电动绞盘,包括电动马达(1)和卷扬筒(2),电动马达(1)用于带动卷扬筒(2)转动,卷扬筒(2)上卷绕有牵引绳(3),电动马达(1)的转轴(25)的一端连接有电磁刹车结构(6),该转轴(25)的另一端连接有齿轮减速结构(7),齿轮减速结构(7)的输出端与卷扬筒(2)连接;齿轮减速结构(7)和电磁刹车结构(6)同时作为刹车方案的组成部分,当电动马达(1)断电停止牵引时,齿轮减速结构(7)利用减速比提供减速阻力,电磁线圈(8)同时断电以使弹性件(12)重新将静盘(9)压紧动盘(10)以刹住动盘(10);该电动绞盘的刹车方案可靠性高、使用方便。
