The invention discloses a three-dimensional hydraulic self-locking jack in the technical field of jacks, the three-dimensional hydraulic self-locking jack comprises an X-axis seat, a Y-axis seat and a Z-axis seat, a Z-axis cylinder is installed in the Z-axis seat, a connecting assembly is installed at the top of the Z-axis cylinder, the left side and the right side of the connecting assembly are connected with a locking mechanism, and the left side and the right side of the connecting assembly are connected with a locking mechanism. The bottoms of the Y-axis base and the Z-axis base are connected with the X-axis base and the Y-axis base through sliding rail assemblies respectively. The connecting frame can be supported and positioned through cooperation of the locking pawl and the fixed limiting teeth or the movable limiting teeth, and therefore the movable end of the Z-axis cylinder is locked through the fixed shaft; when exiting, the arc-shaped locking pawls can be turned over while moving, so that the frictional resistance of the contact roller, the connecting assembly and the supporting seat to the locking pawls is reduced, the turned locking pawls can push the contact roller to be tightly attached to the bottoms of the limiting teeth, and the locking firmness and stability are ensured.

    本发明公开了千斤顶技术领域的一种三维液压自锁式千斤顶,一种三维液压自锁式千斤顶,包括X轴座、Y轴座和Z轴座,所述Z轴座的内部安装有Z轴缸,所述Z轴缸的顶部安装有连接组件,所述连接组件的左右两侧连接有一个锁止机构,所述Y轴座和Z轴座的底部通过滑轨组件分别与X轴座和Y轴座相连接。本发明通过锁止棘爪和固定限位齿或活动限位齿的配合可以对连接架进行支持定位,从而通过固定轴锁止Z轴缸的活动端;弧形锁止棘爪退出时可以在移动的同时使其翻转,进而降低接触辊与连接组件和支撑座对锁止棘爪摩擦阻力,而且翻转的锁止棘爪可以推送接触辊与限位齿的底部紧密贴合,确保锁止的牢固稳定性。
