The invention discloses a three-way jack which comprises a supporting part, a first horizontal jack, a second horizontal jack, a first follow-up part and a second follow-up part. The supporting part is arranged above the first follow-up part, and the first horizontal jack and the second horizontal jack abut against the supporting part. The first follow-up part comprises a first rolling shaft chain, the first rolling shaft chain is arranged in the first direction, the first horizontal jack is used for applying force towards the first direction to the supporting part, and when the first horizontal jack drives the supporting part to move in the first direction, the first rolling shaft chain rolls in the first direction along with the supporting part; the second follow-up part comprises a second rolling shaft chain, the second rolling shaft chain is arranged in the second direction, the second horizontal jack is used for applying force towards the second direction to the supporting part, and when the second horizontal jack drives the supporting part to move in the second direction, the second rolling shaft chain rolls in the second direction along with the supporting part; an included angle exists between the first direction and the second direction, and friction resistance is reduced.
本发明公开了一种三向千斤顶,其包括支撑部、第一水平千斤顶、第二水平千斤顶、第一随动部和第二随动部。支撑部设置于第一随动部的上方,第一水平千斤顶和第二水平千斤顶均与支撑部抵接;第一随动部包括第一滚动轴链,第一滚动轴链沿着第一方向设置,第一水平千斤顶用以对支撑部施加朝向第一方向的力,当第一水平千斤顶带动支撑部沿第一方向移动时,第一滚动轴链跟随支撑部沿第一方向滚动;第二随动部包括第二滚动轴链,第二滚动轴链沿着第二方向设置,第二水平千斤顶用以对支撑部施加朝向第二方向的力,当第二水平千斤顶带动支撑部沿第二方向移动时,第二滚动轴链跟随支撑部沿第二方向滚动;第一方向与第二方向之间存在夹角,减小摩擦阻力。
