The invention provides a follow-up compensation hydraulic control system which comprises a hydraulic control oil way and a follow-up oil cylinder, the follow-up oil cylinder is connected with a follow-up tackle, the follow-up tackle is arranged on a suspension arm of a crane in a sliding mode, and the follow-up tackle is connected with a follow-up hook through a follow-up cable and connected with a lifting hook through a lifting cable. The hydraulic control oil way comprises a follow-up control reversing valve, a first logic valve, a second logic valve and a first energy accumulator, on one hand, the first energy accumulator is connected with one end of the first logic valve through a first oil way, and on the other hand, the first energy accumulator is connected with one end of the second logic valve through a second oil way; the other end of the first logic valve and the other end of the second logic valve are connected with the rodless end of the follow-up oil cylinder. By means of the control system, the lifting hook can be controlled to act according to up-down floating of the ship on the sea, and cargoes are prevented from directly impacting the ship.
本发明提供一种随动补偿液压控制系统,包括液压控制油路和随动油缸,所述随动油缸与随动滑车连接,随动滑车滑动的设置在吊机的吊臂上,随动滑车通过随动缆绳与随动钩连接以及通过起吊缆绳与起重钩连接,液压控制油路包括随动控制换向阀、第一逻辑阀、第二逻辑阀和第一蓄能器,所述第一蓄能器一方面通过第一油路连接第一逻辑阀的一端,第一蓄能器另一方面通过第二油路连接第二逻辑阀的一端,第一逻辑阀的另一端和第二逻辑阀的另一端连接随动油缸的无杆端;通过本发明的控制系统,使得能够根据船在海上的上下浮动从而控制起重钩进行动作,防止货物直接撞击到船。
