The large-stroke high-bearing jack comprises a jack body and two side supporting assemblies, the jack body comprises a supporting assembly, a supporting base and a jacking block, the supporting base and the jacking block are both connected with the supporting assembly, and first fixing plates are fixed to the two sides of the jacking block correspondingly; a first concave block is rotatably mounted at the bottom of the first fixing plate, second fixing plates are fixed to the two sides of the supporting base, extension plates are rotatably mounted at the bottoms of the second fixing plates, second concave blocks are fixed to the tops of the extension plates, and the first concave block and the second concave block on the same side as the first concave block are jointly connected to one side supporting assembly. By the adoption of the side supporting assembly, the situation that the jack body inclines due to the fact that inclination force is too large is avoided, and meanwhile the whole jack body is more stable in a four-point supporting mode.
本发明涉及应用于千斤顶领域的一种大行程高承载的千斤顶,包括千斤顶本体以及两个侧支撑组件,千斤顶本体包括撑起组件、支撑底座以及顶起块,支撑底座以及顶起块均与撑起组件相连接,顶起块的两侧均固定有第一固定板,第一固定板的底部转动安装有第一凹形块,支撑底座的两侧均固定有第二固定板,第二固定板的底部转动安装有延展板,延展板的顶部固定有第二凹形块,第一凹形块以及与其同一侧的第二凹形块共同连接在一个侧支撑组件上,采用上述侧支撑组件,实现防止倾斜力过大,使千斤顶本体发生倾斜,同时通过四点支撑的方式,使整个千斤顶本体更加稳定。
