The invention relates to a frame lifting mechanism and mobile mechanical equipment, the frame lifting mechanism comprises a hydro-pneumatic spring, a cantilever, a rear axle and a frame, the hydro-pneumatic spring and the cantilever are respectively arranged below the frame, the upper end of the hydro-pneumatic spring is hinged with the frame, the lower end of the hydro-pneumatic spring is hinged with one end of the cantilever, and the other end of the cantilever is hinged with the rear axle. The other end of the cantilever is hinged to the frame, and the cantilever is connected to the rear axle. The hydro-pneumatic spring discharges oil to reduce the height, the cantilever is driven to rotate along the hinged position of the cantilever and the frame, the ground clearance of the frame is reduced, and the saddle is conveniently connected with the trailer; the hydro-pneumatic spring injects oil to increase the height, the cantilever is driven to rotate along the hinged position of the cantilever and the frame, the ground clearance of the frame is increased, and therefore the saddle is separated from the trailer. The lifting device is suitable for different vehicle types, high in universality and capable of achieving lifting without manual hand cranking of the front supporting leg, reduces labor intensity and improves working efficiency.

    本发明涉及一种车架升降机构及流动机械设备,车架升降机构包括油气弹簧、悬臂、后桥及车架,所述油气弹簧及悬臂分别设置于所述车架的下方,所述油气弹簧的上端与所述车架铰接,所述油气弹簧的下端与所述悬臂的一端铰接,所述悬臂的另一端铰接于所述车架,所述悬臂连接于所述后桥。油气弹簧卸油降低高度,带动悬臂沿其与车架铰接的位置旋转,降低车架的离地高度,便于鞍座与挂车连接;油气弹簧注油提升高度,带动悬臂沿其与车架铰接的位置旋转,提升车架的离地高度,从而实现鞍座和挂车脱离。适用于不同车型,通用性强,无需人工手摇前支腿实现升降,降低劳动强度并提高工作效率。
