The invention relates to a dump truck hydraulic lifting driving system which comprises a dump truck body, a hydraulic lifting mechanism, a rear baffle locking mechanism, a rear baffle, a fender, an auxiliary frame, a main frame, a carriage and a traveling driving mechanism. The state detection equipment is used for determining whether the dump truck main body is in a traveling state or not based on the driving power of the traveling driving mechanism; the automatic regulation and control mechanism is connected with the hydraulic lifting mechanism and is used for automatically regulating and controlling the set lifting speed of the carriage based on the quantity of the goods to be self-unloaded in the carriage; the hydraulic lifting switch is used for forbidding hydraulic lifting of the hydraulic lifting mechanism when it is detected that the dump truck body is in the running state. According to the invention, a high-precision control mechanism of the self-unloading speed based on the quantity of the to-be-assisted goods and a self-unloading function forbidding mechanism based on the driving state of the dump truck can be introduced, so that accidents of goods overturning and part damage of the dump truck are avoided.
本发明涉及一种自卸车辆液压举升驱动系统,包括:自卸车辆主体,包括驾驶室、液压举升机构、后挡板锁紧机构、后挡板、挡泥板、副车架、主车架、车厢和行驶驱动机构;状态检测设备,用于基于所述行驶驱动机构的驱动功率确定所述自卸车辆主体是否处于行驶状态;自动调控机构,与所述液压举升机构连接,用于基于所述车厢内待自卸货物的多寡执行对车厢的设定升起速率的自动调控;液压举升开关,用于在检测到自卸车辆主体处于行驶状态时禁用所述液压举升机构的液压举升。通过本发明,能够引入基于待协货物数量多寡的自卸速率的高精度控制机制以及基于自卸车辆行驶状态的自卸功能禁用机制,从而避免自卸车辆出现货物倾覆以及部件损伤的事故。
