The invention discloses a lateral-moving single-fork distance-adjusting forklift hydraulic control system with a self-locking function and a forklift. The hydraulic control system comprises an oil pump, a multi-way valve, a right pallet fork distance-adjusting oil cylinder, a left pallet fork distance-adjusting oil cylinder, a bidirectional hydraulic lock and an oil tank. A first working oil port A1 of the multi-way valve is communicated with a rodless cavity of the right pallet fork distance adjusting oil cylinder, a second working oil port B1 of the multi-way valve is communicated with a first connector of the second three-way pipe, a second connector of the second three-way pipe is communicated with a rodless cavity of the left pallet fork distance adjusting oil cylinder, and a third connector of the second three-way pipe is communicated with a fourth working oil port C2 of the two-way hydraulic lock. A third working oil port A2 of the multi-way valve is communicated with a first working oil port V1 of the bidirectional hydraulic lock, and a fourth working oil port B2 of the multi-way valve is communicated with a second working oil port V2 of the bidirectional hydraulic lock. The bidirectional hydraulic lock is arranged on the accessory oil way, so that the problem that the other oil cylinder continues to act after the stroke of one oil cylinder is in place during lateral movement is solved, and the safety of lateral movement operation is improved.

    本发明公开了带自锁功能的侧移单叉调距叉车液压控制系统及叉车,液压控制系统包括油泵、多路阀、右货叉调距油缸、左货叉调距油缸、双向液压锁和油箱;多路阀的第一工作油口A1与右货叉调距油缸的无杆腔连通,多路阀的第二工作油口B1与第二三通管的第一接口连通,第二三通管的第二接口与左货叉调距油缸的无杆腔连通,第二三通管的第三接口与双向液压锁的第四工作油口C2连通,多路阀的第三工作油口A2与双向液压锁的第一工作油口V1连通,多路阀的第四工作油口B2与双向液压锁的第二工作油口V2连通。本发明通过在属具油路上设置一双向液压锁,解决了侧移动作时,在一个油缸行程到位后,另一个油缸继续动作问题,提高了侧移运行的安全性。
