Active and passive motion compensation trestle amplitude variation system and trestle thereof
The invention discloses an active and passive motion compensation trestle amplitude variation system which comprises a servo valve PS, a driving oil cylinder, a driving and driven oil cylinder, an energy accumulator and a high-pressure nitrogen cylinder set, wherein the driving oil cylinder is a single-action hydraulic cylinder, and an oil cavity of the driving oil cylinder is a cavity; the driving and driven oil cylinder is a double-acting hydraulic cylinder, a rod cavity thereof is a cavity b, and a rodless cavity thereof is a cavity c; the energy accumulator is arranged on the driving and driven oil cylinder, the oil end of the energy accumulator is connected with the cavity c of the driving and driven oil cylinder through using an isolating valve set, and the gas end of the energy accumulator is connected with the high-pressure nitrogen cylinder set; and the servo valve PS is used for controlling the driving oil cylinder and the driving and driven oil cylinder, and the servo valve PS is connected with a hydraulic energy accumulator set. The invention further discloses a trestle comprising the active and passive motion compensation trestle amplitude variation system. A three-cavity composite oil cylinder is replaced by the double hydraulic cylinders, and the defects in the prior art are overcome.
本发明公开了一种主被动运动补偿栈桥变幅系统，包括伺服阀PS、主动油缸、主被动油缸、蓄能器和高压氮气瓶组；所述主动油缸为单作用液压缸，其油腔为a腔；所述主被动油缸为双作用液压缸，其有杆腔为b腔，无杆腔为c腔；所述蓄能器设于所述主被动油缸上，所述蓄能器的油端通过隔离阀组与所述主被动油缸的c腔相连，所述蓄能器的气端与所述高压氮气瓶组相连；所述伺服阀PS用以控制所述主动油缸与所述主被动油缸，所述伺服阀PS上连有液压蓄能器组。本发明还公开了一种包含所述的主被动运动补偿栈桥变幅系统的栈桥。本发明采用双液压缸代替三腔复合油缸，解决现有技术中存在的缺陷及不足。
