The invention discloses a cable winding and unwinding device which is used for ship docking. The device mainly comprises a cable, a winch, a pay-off wheel and a fixing frame. A plurality of rollers are mounted at the periphery of the pay-off wheel; the working principle is as follows: when a hoist tightens the cable, the winch rotates clockwise to withdraw the corresponding cable and wind the cable on the winch; meanwhile, a composite pipe fixed on the winch pulls the pay-off wheel to rotate anticlockwise; meanwhile, the composite pipe wound on the pay-off wheel relatively slides along the multiple rollers and is wound on the winch; and at the moment, the wire outlet end of the composite pipe wound on the pay-off wheel does not pay off wires due to counterclockwise rotation of the pay-offwheel under the action of leftward tension; when the cable is loosened, the winch rotates anticlockwise to pay off the corresponding cable, and meanwhile, the pay-off wheel rotates clockwise to wind the composite pipe wound on the winch on the pay-off wheel.
本发明公开了一种收放缆装置,用于船舶停靠使用,它主要包括缆索、绞盘、放线轱辘、固定架,放线轱辘的外周安装有多个辊轮,其工作原理是:当卷扬机紧缆时,其绞盘顺时针转动将相应的缆索收回并绕在绞盘上,同时固定在绞盘上的复合管拉动放线轱辘反时针转动,同时绕在放线轱辘上的复合管沿多个辊轮相对滑动并将其绕在绞盘上,此时绕在放线轱辘上的复合管的出线端由于受到向左的拉力作用,其出线端不会因为放线轱辘的反时针转动而放线;当松缆时,其绞盘反时针转动将相应的缆索放出,同时放线轱辘顺时针转动将绕在绞盘上的复合管绕在放线轱辘上。
