The invention discloses a fork distance adjusting system and a control method, the distance adjusting system comprises a left fork and a right fork, the left fork is mounted on a forklift frame through a left distance adjusting oil cylinder, and the right fork is mounted on the forklift frame through a right distance adjusting oil cylinder; oil ways of the left distance adjusting oil cylinder and the right distance adjusting oil cylinder are connected with an oil pump through an electromagnetic valve, and a circuit of the oil pump is connected with a pump motor. Piston rods of the left distance adjusting oil cylinder and the right distance adjusting oil cylinder drive the left pallet fork and the right pallet fork to move face to face or back to back. The distance between the left pallet fork and the right pallet fork is detected through the displacement sensor, the hydraulic system is accurately controlled to horizontally move the left pallet fork and the right pallet fork according to target data of the distance between the pallet forks, and the distance between the left pallet fork and the right pallet fork is made to be within the control target error range.

    本发明公开了一种货叉间距的调距系统及控制方法,调距系统包括左货叉和右货叉,所述左货叉通过左调距油缸安装在叉车架上,右货叉通过右调距油缸安装在叉车架上;所述左、右调距油缸的油路通过电磁阀与油泵连接,所述油泵的电路与泵电机连接;所述左、右调距油缸的活塞杆带动左、右货叉相向或相背运动。本申请采用位移传感器检测左、右货叉间距,并根据货叉间距的目标数据来精确地控制液压系统进行水平移动左、右货叉,使左、右货叉间距落在控制目标误差范围内。
