The invention relates to the technical field of jacks for coal mines, and discloses an adjustable jack positioning device for coal mines, which comprises two arc-shaped frames, arc-shaped grooves are respectively formed in the upper surfaces of the two arc-shaped frames, and arc-shaped racks are connected to the outer walls of the two arc-shaped frames; adjusting assemblies used for adjusting the angle of the jack are arranged on the arc-shaped groove of the arc-shaped frame and the arc-shaped rack, and the adjusting assemblies move along the arc-shaped tracks of the arc-shaped frame and the arc-shaped rack. Through the arrangement of the adjusting assembly, the rolling wheel slides on the inner wall of the sliding groove of the arc-shaped frame, it is guaranteed that the adjusting assembly moves along the arc-shaped track, an output shaft of the motor penetrates through the rolling wheel and is connected with the gear, and the gear is meshed with the arc-shaped rack; therefore, angle adjustment of the jack is achieved, and different angle requirements in a coal mine are met.

    本发明涉及煤矿用的千斤顶技术领域,且公开了一种煤矿用的千斤顶可调定位装置,包括两个弧形架的上表面分别设置有弧形槽,两个弧形架的外壁上连接有弧形齿条,弧形架的弧形槽和弧形齿条上设置有用于对千斤顶进行角度调整的调整组件,调整组件沿着弧形架和弧形齿条的弧形轨迹进行移动。本发明通过调整组件的设置,滚轮在弧形架的滑动槽内壁上滑动,保证调整组件沿着弧形轨迹移动,电机的输出轴贯穿滚轮并连接齿轮,齿轮与弧形齿条相互啮合,当电机启动时,齿轮沿着弧形齿条转动,带动滚轮沿着弧形架移动,从而实现对千斤顶的角度调整,从而适应煤矿中不同的角度需求。
