The invention provides a rotary damping control hydraulic system which is used for lap joint of an offshore trestle and comprises a rotary system, a main oil inlet, a main oil outlet, a main control oil port and an oil tank. The rotary system comprises a rotary proportional valve, a first balance valve, a second balance valve, a first shuttle valve, a left hydraulic motor, a right hydraulic motor, a left brake, a right brake, an overflow oil bridge brake valve and an electromagnetic directional valve; when the maritime work trestle is switched from the follow-up working condition to the normal working condition, oil ways in the two rotating directions are not communicated, and therefore the situation that rotation of the trestle is out of control is avoided.
本发明提供一种回转阻尼控制液压系统,用于海上栈桥搭接,包括回转系统、主进油口、主出油口、主控制油口和油箱;回转系统包括回转比例阀、第一平衡阀、第二平衡阀、第一梭阀、左液压马达、右液压马达、左刹车、右刹车、溢流油桥制动阀和电磁换向阀;本发明在海工栈桥在从随动工况切换到正常工况时,两个转动方向的油路不会连通,从而栈桥不会出现回转失控的情况。
