The invention provides a dumper lifting device, and relates to the technical field of dumper lifting devices, the dumper lifting device comprises a hydraulic lifting cylinder, the tail end parts of a retaining ring and a shaft sleeve are jointly provided with a circle of insertion plates in a penetrating and sliding manner, and the head end parts of the circle of insertion plates are matched with an annular positioning groove in an insertion manner; the part, located between the retaining ring and the limiting ring, of the shaft sleeve is slidably sleeved with a driving ring, and connecting rods are rotationally connected between the driving ring and the circle of inserting plate. An inclined positioning shaft is welded to the periphery of the limiting ring, and an L-shaped driving rod which is pushed and positioned through a spring is installed on the inclined positioning shaft in a sliding mode. And the shaft pin is in running fit with the shaft pin sleeve in a penetrating manner. The two L-shaped driving rods can slide up and down and drive the two circles of inserting plates to be synchronously pulled and inserted inwards and outwards to lock and unlock the shaft pin by utilizing the telescopic driving force generated when the hydraulic lifting cylinder pushes the two second auxiliary supporting rods up and down and the carriage in the overhauling process, and therefore the trouble that the two L-shaped driving rods need to be additionally manually operated to lock and unlock the shaft pin can be omitted.
本发明提供一种自卸车举升装置,涉及车辆举升装置技术领域,包括液压举升缸,所述保持圈与轴套的尾端部分共同贯穿滑动安装有一圈插板,一圈插板的首端部分均与环形定位槽插接配合;所述轴套上位于保持圈和限位环之间的部分滑动套装有驱动环,驱动环与一圈插板之间均转动连接有连杆;所述限位环的外周焊接有倾斜定位轴,倾斜定位轴上滑动安装有通过弹簧顶推定位的L状驱动杆;所述轴销与轴销套贯穿转动配合。两处L状驱动杆可利用在检修过程中,液压举升缸上下顶推两处第二辅助撑杆以及车厢的伸缩驱动力,上下滑动并驱使两圈插板同步内外抽插对轴销实施锁定和解锁,这可省去需额外手动操作两处L状驱动杆对轴销实施锁定和解锁的麻烦。
