The invention provides a single-cylinder bolt telescopic system and a control method. The system comprises a telescopic oil cylinder; the driving end comprises a first energy accumulator and a second energy accumulator, wherein the first energy accumulator is connected to a P port of the cylinder arm pin switching valve and a first oil port of the sequence valve through a first connecting oil way; a port A of the cylinder arm pin switching valve is connected to a second oil port of the sequence valve; a first control end of the sequence valve is connected to the third energy accumulator; a second control end of the sequence valve is connected to an oil path between the second oil port and the port A of the cylinder arm pin switching valve; a third oil port of the sequence valve is connected to a rodless cavity of the arm pin oil cylinder; the first energy accumulator is connected to a port T of the cylinder arm pin switching valve through a second connecting oil way; a port B of the cylinder arm pin switching valve is connected to a rodless cavity of the cylinder pin oil cylinder. And a rodless cavity of the liquid storage oil cylinder is connected with the second energy accumulator and a rod cavity of the telescopic oil cylinder. The hydraulic oil way for driving the arm pin mechanism of the cylinder to act is independent of the action of the telescopic oil cylinder, and meanwhile, a movable core pipe in the telescopic oil cylinder is omitted.
本发明提出了一种单缸插销伸缩系统及控制方法,该系统包括伸缩油缸;驱动端包括:第一蓄能器,第一蓄能器通过第一连接油路连接至缸臂销切换阀的P口、顺序阀的第一油口;缸臂销切换阀的A口连接至顺序阀的第二油口;顺序阀的第一控制端连接至第三蓄能器;顺序阀的第二控制端连接至第二油口和缸臂销切换阀A口之间的油路;顺序阀的第三油口连接至臂销油缸的无杆腔;第一蓄能器通过第二连接油路连接至缸臂销切换阀的T口;缸臂销切换阀的B口连接至缸销油缸的无杆腔;储液油缸,其无杆腔连接第二蓄能器和伸缩油缸的有杆腔。本发明驱动缸臂销机构动作的液压油路与伸缩油缸的动作相互独立,同时取消了伸缩油缸内的活动芯管。
