The invention relates to the technical field of hydraulic lifting of dump trucks, in particular to a front hydraulic lifting device of a heavy dump truck. Comprising two sets of frames and a carriage, one ends of the two sets of frames are fixedly connected with a front fixing plate, a first lifting bracket is arranged on the front fixing plate, a lifting hydraulic cylinder is rotationally connected to the first lifting bracket, an oil tank is arranged on the front fixing plate, an oil pipe is communicated between the oil tank and the lifting hydraulic cylinder, and the oil pipe is connected with a hydraulic cylinder. A second lifting bracket is fixedly connected to the carriage, oil in an oil tank is pressurized and then enters a lifting hydraulic cylinder, the end of a telescopic connecting rod drives a sleeve to ascend, a first hinge base connected to the bottom of the carriage drives the ends of two sets of supporting shafts to ascend, a supporting assembly is pulled, and the supporting assembly is in meshed connection with a rack through a limiting mechanism. In the moving process of the supporting assembly, the two sets of supporting shafts have the auxiliary supporting effect on the carriage, the stress of the telescopic connecting rod is effectively relieved, and the carriage lifting stability is effectively improved.

    本发明涉及自卸汽车液压举升技术领域,特别涉及一种重卡自卸车前置液压举升装置。包括两组车架和车厢,两组所述车架的一端固定连接有前固定板,所述前固定板上设置有第一举升托架,所述第一举升托架上转动连接有举升液压缸,所述前固定板上设置有油箱,所述油箱与举升液压缸之间连通有油管,所述车厢上固定连接有第二举升托架,通过使油箱内的油加压后进入举升液压缸内,使伸缩连杆的端部带动套筒上升,连接在车厢底部的第一铰接座带动两组支撑轴的端部上升,拉动支撑组件,通过限位机构与齿条啮合连接,使支撑组件移动过程中,两组支撑轴对车厢产生辅助支撑的作用,有效减轻伸缩连杆的受力,有效提升车厢举升的稳定性。
