The invention relates to the field of rail vehicle gauge changing, and provides a thrust conversion mechanism, an unlocking device, a gauge changing wheel set and a ground rail changing facility. Thethrust conversion mechanism comprises a mounting base, a pushing shaft and a swinging body; a guide through hole extending in the horizontal direction is formed in the mounting base, and a connectingend is arranged at the position, located below the guide through hole, of the mounting base. One end of the pushing shaft is movably arranged in the guide through hole in a penetrating mode, and a sliding groove extending in the vertical direction from the bottom face of the pushing shaft is formed in the end, located outside the guide through hole, of the pushing shaft; the swinging body is provided with a rotating end and a pushing end, the swinging body is installed below the pushing shaft, the rotating end is rotatably connected with the connecting end in a vertical plane, and the pushingend is rotatably arranged in the sliding groove and can vertically slide along the sliding groove; when the swinging body is subjected to upward lifting force, the rotating end of the swinging body rotates around the connecting end, and the pushing end is driven to slide along the sliding groove and rotate in the direction close to the mounting base so as to apply axial thrust to the pushing shaft. Track changing is simple, and the track gauge changing reliability is high.
本发明涉及轨道车辆变轨距领域,提供推力转换机构、解锁装置、变轨距轮对及地面变轨设施。该推力转换机构包括安装座,安装座开设有沿水平方向延伸的导向通孔,安装座在位于导向通孔的下方部位构造有连接端;顶推轴,一端可移动地穿设在导向通孔中,顶推轴位于导向通孔外的一端开设有由顶推轴的底面沿竖向延伸的滑槽;摆动体,构造有转动端和顶推端,摆动体安装在顶推轴的下方,转动端与连接端在竖直平面内转动连接,顶推端可转动地设于滑槽中并可沿滑槽竖向滑动;在摆动体受到向上的抬升力,摆动体的转动端绕连接端转动,带动顶推端沿滑槽滑动并朝向靠近安装座的方向转动,以对顶推轴施加轴向推力。本发明变轨操作简单、变轨距可靠性高。
