The invention belongs to the field of ship engineering, and particularly discloses a pontoon type dock gate opening and closing method without tug assistance, which comprises the following steps: a positioning winch is additionally arranged at the corner of a dock entrance and a jetty, so that four winches are arranged at the dock entrance for combined operation for opening and closing a pontoon type dock gate; a mooring worker connects the bollards at the corners of the floating box type dock gate with the four winches of the harbor basin through the mooring ropes, the winches are started, the mooring ropes are straightened, and the floating length of the dock gate is reserved; closing the irrigation valve, draining water and floating the dock gate. The buoyancy tank type dock gate is pulled to the edge of the jetty from the dock entrance through the combined pulling and releasing operation of the four winches; the pontoon type dock gate upper bollard is connected with the jetty wharf bollard, and the number of the fixing cables is not less than four. The device does not need tug assistance, saves tug platform fare, and is safe and environment-friendly as the operation winch is powered by a power supply.

    本发明属于船舶工程领域,具体公开了一种无需拖轮协助的浮箱式坞门启闭方法,包括如下步骤:在坞口与突堤转角处,新增一台定位绞盘,使得坞口处共有四个绞盘组合操作,供浮箱式坞门启闭使用;系缆工通过缆绳将浮箱式坞门角部系船柱与港池四个绞盘相连,启动绞盘,将缆绳拉直,但留有坞门上浮长度;确保坞门两边水位相平,关闭灌水阀门,排水上浮坞门。通过四台绞盘组合拉放操作,将浮箱式坞门从坞口拉至突堤边;将浮箱式坞门上部系船柱与突堤码头系船柱相连,固定缆绳数不少于四根。本发明不需拖轮协助,节省了拖轮台班费,同时操作绞盘动力为电源,安全环保。
