The invention relates to the technical field of dump trucks, in particular to a dump truck anti-back-bucket device, which comprises a protection mechanism comprising a truck body, a hydraulic lifting cylinder arranged on the truck body, a box bucket connected with the truck body, and a protection component arranged on the truck body; the blocking mechanism comprises a trigger component arranged on the vehicle body and a protection component arranged on the vehicle body; wherein the end, away from the vehicle body, of the hydraulic lifting cylinder is connected with the box hopper, a part of the triggering component is located in the protection component, the damping oil cylinder is arranged at the tail of the vehicle body, and when the gravity center of materials exceeds the gravity center of the box hopper in the lifting process of the box hopper, the damping oil cylinder generates reverse force for preventing the box hopper from continuing to act; the damping oil cylinder is used for counteracting part of lifting force generated by downward movement of the gravity center of materials, and the maximum reverse force is generated when the hydraulic lifting cylinder is about to reach the longest extension length along with gradual increase of the reverse force generated by continuous compression of the damping oil cylinder.
本发明涉及自卸车技术领域,尤其是一种自卸车防背斗装置,包括,防护机构,包括车身、设置于所述车身上的液压举升缸、与所述车身连接的箱斗,以及设置于所述车身上的防护部件;阻断机构,包括设置于所述车身上的触发部件,以及设置于所述车身上的保护部件;其中,所述液压举升缸远离车身的一端与箱斗连接,所述触发部件的一部分位于防护部件内,通过在车身的尾部设置阻尼油缸,箱斗举升过程中物料的重心超过箱斗重心的时候,阻尼油缸产生阻止箱斗继续动作的反向力,用于抵消部分由于物料重心下移产生的举升力,并随着阻尼油缸的持续压缩产生的反向力逐渐增大,待液压举升缸将要到达最长伸出长度时产生最大反向力。
