The invention discloses a three-capstan traction winch which comprises a traction winch rack, a capstan transmission system is installed on the traction winch rack, a driven capstan, a small capstan and a driving capstan are sequentially installed on a shaft of the capstan transmission system, a cable penetrates in from the end of the driving capstan, and the driven capstan and the driving capstan synchronously rotate in the same direction. Meanwhile, the small capstan, the driven capstan and the driving capstan synchronously and reversely rotate, and the traction cable sequentially penetrates through the driving capstan, the small capstan and the driven capstan and then goes out of the driven capstan end. According to the three-winch traction winch, the tension of the cable outlet end of the cable can be reduced to 1/2 of the tension of the cable outlet end of a double-winch traction winch, and therefore the cable force reducing capacity of the traction winch is improved by nearly 100%. Under the same cable force reducing capacity, the winch grooves can be reduced, so that the weight of the whole winch device is reduced, and the purpose of light weight is achieved. The appearance of the traction winch is smaller and more compact than that of a double-winch winch, and winch grooves can be reduced by nearly half.

    本发明公开了一种三绞盘牵引绞车,该三绞盘牵引绞车包括牵引绞车机架,牵引绞车机架上安装有绞盘传动系统,所述绞盘传动系统的轴上依次安装有从动绞盘、小绞盘、驱动绞盘,缆绳从驱动绞盘端穿入,从动绞盘和驱动绞盘同步同向转动,同时小绞盘与从动绞盘和驱动绞盘同步反向转动,牵引缆绳依次穿过驱动绞盘、小绞盘、从动绞盘后从从动绞盘端出去。本发明三绞盘牵引绞车可以使缆绳出缆端张力减少到双绞盘牵引绞车出缆端张力的1/2,因而使牵引绞车缆绳减力能力提升接近100%。在同等的缆绳减力能力下,绞盘槽可以减少,从而使得整个绞车装置重量减轻,达到轻量化目的。本发明牵引绞车的外形较双绞盘绞车外形小,紧凑,绞盘槽可以减少将近一半。
