According to the steering control system of the long-arm-support trolley and the operation trolley adopting the steering control system, a steering gear is adopted for providing pressure oil for chassis steering and arm support deflection, pressure oil switching is achieved through a first electric control reversing valve, the steering gear can be used for controlling front-end arm support deflection, emergency power does not need to be switched, and the steering control system is simple in structure, convenient to use and high in practicability. And the deflection of the arm support at the front end can be completed by directly operating a steering wheel in a cab without switching and controlling a multi-way valve or remotely controlling, so that the steering operation of the long-arm-support operation trolley when the long-arm-support operation trolley passes through a narrow curve is greatly simplified, and the operation difficulty is reduced. Moreover, the steering following memory cylinder memorizes oil entering the arm support deflection driving part in the deflection process of the calibration arm support, then the steering gear is locked to return to the original position, after deflection of the arm support is completed, the steering gear can return to the original chassis steering stopping position from the original position by operating the steering wheel in the opposite direction, it is guaranteed that the chassis steering action is coherent, and the steering efficiency is improved. And chassis advancing and steering are not affected.

    本发明公开了一种长臂架台车的转向控制系统及采用其的作业台车,其采用转向器为底盘转向和臂架偏摆提供压力油,并通过第一电控换向阀实现压力油切换,可利用转向器操控前端臂架偏摆,无需切换应急动力,也无需切换控制多路阀或遥控,直接在驾驶室用方向盘操作即可完成前端臂架的偏摆,极大地简化了长臂架作业台车在过狭小弯道时的转向操作,减少了作业难度。并且,通过转向跟随记忆缸记忆标定臂架偏摆过程中进入臂架偏摆驱动件的油液,进而锁定转向器的回归原位,待臂架偏摆完成后,通过反方向操作方向盘,转向器即可从回归原位复位至原底盘转向的停止位置,保证底盘转向动作连贯,不会影响底盘行进转向。
