The invention discloses a movable hydraulic grab bucket control system for bulk cargo loading and unloading. The system structurally comprises a storage device of a transmission medium of a hydraulicsystem, namely an oil tank device, wherein the oil tank device is communicated with a gas tank through a communicating vessel, and a communicating port is formed above the liquid level of oil. The system further comprises a pump unit used for providing a power source for the hydraulic system, wherein the pump unit is mainly formed by connecting a motor with a hydraulic pump through a coupler; andthe coupler and the hydraulic pump are arranged in the oil tank device, the oil tank device is sealed through a pump sleeve and an oil tank flange, a transition flange plate and an oil path block areinstalled on the oil tank flange, hydraulic elements used by the system are arranged in the oil path block in a centralized mode, and an executing device of the system is connected with a grab bucketmechanical body. The oil tank of the system is designed to be a closed oil tank with a pre-pressing function, all the hydraulic elements used by the system are of an inserted type and intensively arranged in the oil path block, pipeline connection is reduced, the installation space is reduced, the weight is reduced, and the system is suitable for mobile equipment to use, easy to implement and suitable for application and popularization.

    本发明公开了一种散料装卸用移动式液压抓斗控制系统,结构包括:液压系统传动介质的存储装置油箱装置,油箱装置与气罐通过连通器连通,连通口设置在油液液面以上位置;还包括为液压系统提供动力源的泵机组,泵机组主要由电机通过联轴器与液压泵连接组成;联轴器和液压泵设置在油箱装置内部,通过泵套和油箱法兰将油箱装置密闭,油箱法兰之上安装设置有过渡法兰盘和油路块,系统所用的液压元件集中布置有油路块内,系统的执行器件与抓斗机械本体连接;本发明油箱设计成带预压式密闭油箱,系统所用液压元件全部为插装式,集中布置在油路块里,减少管路连接,减小安装空间,减轻重量,适合移动式装备使用,易于实现,适合推广应用。
