The invention discloses a high-sealing type hydraulic pushing jack, which relates to the technical field of hydraulic oil cylinders and comprises a cylinder body assembly, a piston rod, a piston head and a sealing assembly. The invention further discloses a using method of the high-sealing type hydraulic pushing jack. The using method comprises the following steps of equipment installation, target jacking, target releasing and equipment maintenance. According to the invention, the cylinder body assembly is arranged, the piston rod is arranged in the cylinder body assembly, the sealing assembly is arranged at one end of the cylinder body assembly, the sealing assembly comprises the sealing seat, and the sealing seat can realize sealing between the cylinder body assembly and the piston rod; the arrangement of the dirt blocking pad can effectively prevent the piston rod from bringing sludge and dust into the cylinder body assembly, the outer layer pad is arranged at one end of the dirt blocking pad, the dirt blocking pad is prevented from moving along with the piston rod, the dirt blocking effect of the dirt blocking pad is guaranteed, meanwhile, automatic cleaning of the dirt containing ring can be achieved, the workload is reduced, and the service life is prolonged.

    本发明公开了一种高密封式液压推移千斤顶,涉及到液压油缸技术领域,包括缸体组件、活塞杆、活塞头以及密封组件。还公开了一种高密封式液压推移千斤顶的使用方法,包括以下步骤:设备安装,目标顶起,目标释放以及设备维护。本发明通过设置缸体组件,缸体组件的内部设置有活塞杆,缸体组件的一端设置有密封组件,密封组件包括密封座,密封座可以实现缸体组件与活塞杆之间的密封,通过在密封座的一端设置阻污垫,阻污垫的设置可以有效的阻挡活塞杆将污泥和灰尘带入缸体组件内部,通过在阻污垫的一端设置外层垫,避免了阻污垫跟随活塞杆运动,保证了阻污垫的阻污效果,同时还能实现纳污环的自动清理,降低工作量,提高使用寿命。
