The invention relates to a hanging and locking device of a high-speed telescopic arm forklift. Comprising an oil cylinder mounting seat, a limiting seat and a locking rod, wherein the oil cylinder mounting seat is fixedly connected to a vehicle girder and is far away from the upper left side of a vehicle front axle axis; the limiting seat is fixedly connected to the vehicle girder and is close to the upper left side of the vehicle front axle axis; the lower end of the locking rod corresponds to the middle part of the suspension plate spring; a base of the locking oil cylinder is hinged to the oil cylinder installation base through a pin shaft, and a piston of the locking oil cylinder is hinged to the upper end of the locking rod. A bidirectional hydraulic lock is arranged on the locking oil cylinder, and a piston of the locking oil cylinder can stretch out or retract by electrically operating the bidirectional hydraulic lock. The suspension plate spring locking device can lock the suspension plate spring when the high-speed telescopic arm forklift works, so that the suspension plate spring has reliable integrity, the safety of fork loading operation is improved, and the organic combination of high-speed maneuvering and low-speed loading and unloading functions is realized.

    本发明涉及一种高速伸缩臂叉车悬挂锁紧装置,包括固定连接在车辆大梁上且远离车辆前桥轴线左侧上方的油缸安装座、固定连接在车辆大梁上且靠近车辆前桥轴线左侧上方的限位座、中部偏上部位铰接在车辆大梁上且与车辆前桥轴线正对的锁紧杆,所述锁紧杆紧靠限位座右侧且下端与悬挂板弹簧的中部对应;还包括底座通过销轴铰接在所述油缸安装座上的锁紧油缸,所述锁紧油缸的活塞与所述锁紧杆的上端铰接;在所述锁紧油缸上设有双向液压锁,电动操作双向液压锁能够使锁紧油缸的活塞伸出或缩回。其能够在高速伸缩臂叉车作业时将悬挂板弹簧锁紧,使之具有可靠的整体性,提高叉装作业的安全性,实现高速机动和低速装卸功能的有机结合。
