The invention relates to the technical field of jacks, in particular to a hydraulic jacking device. The hydraulic jacking device comprises a hydraulic jacking mechanism, a hydraulic base and a pressing assembly, the hydraulic base is connected to the side wall of the hydraulic jacking mechanism, and one end of the pressing assembly is fixed to a pressing piston of the hydraulic base. The pressing assembly is an assembly which can elastically stretch out and draw back with the fixed point position of the pressing assembly on the pressing piston as a stress point, and the pressing assembly is in a contracted state when not bearing pulling force. By means of the pressing assembly of the pressing piston fixed to the hydraulic base, a traditional separated pressing rod is improved to be directly fixed to the hydraulic base in a telescopic mode, use is convenient and fast, loss is not likely to happen, and the problem that due to the fact that an existing pressure rod and an existing pressing piston are combined in a separated mode and the pressure rod is often forgotten to be carried in actual operation, the problem that a jack cannot be pressed or jacked up is solved.
本发明涉及千斤顶技术领域,尤其涉及一种液压顶撑装置,其包括:液压顶起机构、液压座和按压组件,其中:所述液压座连接在液压顶起机构的侧壁上,所述按压组件的一端固定在液压座的按压活塞上,且该按压组件为能够以其在压活塞上的固定点位为受力点而进行弹性伸缩的组件,且在按压组件不受拉力时其处于被收缩状态。本发明通过固定在液压座的按压活塞的按压组件,将传统的分离式压杆改进为伸缩式直接固定在液压座上,使用便捷,不易丢失,有效克服了现有的压力杆与按压活塞之间为分离组合的,在实际操作中经常发生压力杆忘记携带的情况,导致无法对千斤顶进行按压顶起的问题。
