The invention provides a wave compensation type closed telescopic pump control hydraulic system for a maritime work trestle, which comprises a hydraulic main loop, an auxiliary oil source device and a constant pressure air source device, and the hydraulic main loop comprises a servo motor, a two-way constant displacement pump, an overflow valve group, a one-way valve group, a reversing valve group, a pressure reducing valve, a sensor and a two-way pump motor; three wave compensation modes of active compensation, constant thrust compensation and floating compensation are achieved through the hydraulic main loop, the auxiliary oil source device and the constant-pressure air source device, and contact with the side face of a target platform with constant extrusion force is achieved through the constant thrust compensation mode when the offshore platform does not support rigid connection; the method is jointly realized through an active compensation mode and a floating compensation mode, when the method faces an offshore platform supporting rigid connection, rigid connection is completed, self-adaptive compensation is carried out along with wave fluctuation, and energy consumption is reduced.

    本发明提供一种用于海工栈桥的波浪补偿型闭式伸缩泵控液压系统,其包括液压主回路、辅助油源装置和恒压气源装置,液压主回路包括伺服电机、双向定量泵、溢流阀组、单向阀组、换向阀组、减压阀、传感器和双向泵马达;本发明通过液压主回路、辅助油源装置和恒压气源装置,实现主动补偿、恒推力补偿、浮动补偿三种波浪补偿模式,通过恒推力补偿模式,实现在不支持刚性连接的海上平台时,与目标平台的侧面以恒定的挤压力保持接触,通过主动补偿模式与浮动补充模式共同实现,在面对支持刚性连接的海上平台时,完成刚性连接并跟随海浪波动进行自适应补偿,降低能耗。
