The invention relates to the technical field of forklifts, in particular to a fork hydraulic distance adjusting system for a forklift, which comprises an oil cylinder group, an inner fork and an outer fork are arranged at two ends of the oil cylinder group, and the inner fork and the outer fork are L-shaped; the oil cylinder set comprises two symmetrically-distributed outer cylinders, inner cylinders are movably inserted into inner cavities of one ends of the outer cylinders, movable columns are movably inserted into inner cavities of one ends of the inner cylinders, one ends of the inner cylinders are fixed to the first sleeve plate, and one ends of the movable columns movably penetrate through the first sleeve plate and are fixed to the first protruding blocks. The forklift has the beneficial effects that the oil cylinder set is arranged between the two pallet forks and comprises the two symmetrically-distributed outer barrels, the inner barrels are movably inserted into the inner cavities of one ends of the outer barrels, the sealing barrels are fixed to the outer sides of the other ends of the outer barrels, and the inner cavities of the sealing barrels can be communicated with the inner cavities of the outer barrels or the inner cavities of the inner barrels by rotating the adjusting rotary disc; therefore, stretching of the inner barrel or stretching of the movable column can be controlled, switching of single supporting and double supporting of the pallet fork and adjustment of the distance are achieved, and therefore the equipment cost and the failure rate are reduced.

    本发明涉及叉车技术领域,具体为一种叉车用货叉液压调距系统,包括:油缸组,油缸组的两端均设置有内叉和外叉、且内叉和外叉均呈“L”字形;油缸组包括两个对称分布的外筒,外筒的一端内腔活动插接有内筒,内筒的一端内腔活动插接有活动柱,内筒的一端与套板一固定,活动柱的一端活动贯穿套板一并与凸块一固定;有益效果为:通过在两组货叉之间设置有油缸组,油缸组包括两个对称分布的外筒,外筒一端内腔活动插接内筒、且另一端外侧固定有密封筒,通过旋转调节转盘能够将密封筒内腔接通外筒内腔或者内筒内腔,从而能够控制内筒的伸缩或者活动柱的伸缩,实现货叉单双托的切换、以及间距的调节,从而降低了设备成本以及故障率。
