The invention provides a trestle interactive compensation method, which comprises the following steps of: installing a detection wheel at the head part of a trestle telescopic channel, then calculating the telescopic distance of a piston in a single piston rod cylinder of a compensation hydraulic system through a PID (Proportion Integration Differentiation) control module according to the numerical value of an encoder arranged on the detection wheel; the servo proportional reversing valve is communicated with a second oil way, liquid oil passes through a one-way valve I in the combination valve and then is directly connected with a valve port A1 of the single-piston-rod cylinder, a piston of the single-piston-rod cylinder is pushed to stretch out, and then the trestle is driven to stretch; when the trestle needs to retract in active compensation, the servo proportional reversing valve communicates with a third oil way, liquid oil passes through a fourth one-way valve in the combination valve and then is directly connected with an A2 valve port of the single-piston-rod cylinder, a piston of the single-piston-rod cylinder is pushed to retract, and then the trestle is driven to be shortened. And meanwhile, a hydraulic system for driving the trestle can be controlled not to be damaged, practicability is high, and the method is reliable.

    本发明提供一种栈桥互动补偿方法,将检测轮安装在栈桥伸缩通道的头部,然后根据设置在检测轮上编码器的数值通过PID控制模块计算出补偿液压系统的单活塞杆缸中活塞伸缩的距离,在栈桥主动补偿中需要伸出时,伺服比例换向阀与第二油路联通,液油通过组合阀中的单向阀一后直接与单活塞杆缸的A1阀口连接,推动单活塞杆缸的活塞伸出,进而驱动栈桥伸长;在栈桥主动补偿中需要缩回时,伺服比例换向阀与第三油路联通,液油通过组合阀中的单向阀四后直接与单活塞杆缸的A2阀口连接,推动单活塞杆缸的活塞缩回,进而带动栈桥缩短,本发明能够实现栈桥伸缩的主动补偿,同时能够控制驱动栈桥的液压系统不被损坏,实用性高且方法可靠。
