The invention relates to the technical field of supporting devices, and discloses a large-tonnage planetary roller screw supporting leg which comprises a second mounting box, the bottom side of the second mounting box is fixedly connected with a first mounting box and a third mounting box, and the end, away from the second mounting box, of the first mounting box is fixedly connected with a reduction gearbox. A fixed motor is arranged at the end, away from the first mounting box, of the reduction gearbox, a movable speed reducer is arranged in the reduction gearbox, the output end of the motor is fixedly connected with the input end of the speed reducer, and a movable small bevel gear and a movable large bevel gear are arranged in the first mounting box. According to the vehicle evacuation device, the manual tool is manually rotated, the manual tool drives the small bevel gear to rotate so as to drive the planetary ball screw to rotate and enable the planetary ball nut to move, and when power is suddenly cut off, the supporting block can be withdrawn in a manual adjustment mode, so that the vehicle completes a rapid evacuation action.

    本发明涉及支撑装置技术领域,且公开了一种大吨位行星滚柱丝杠撑腿,包括第二安装箱,第二安装箱的底侧固定连接有第一安装箱和第三安装箱,第一安装箱远离第二安装箱的一端固定连接有减速箱,减速箱远离第一安装箱的一端设置有固定的电机,减速箱的内部设置有活动的减速机,电机的输出端与减速机的输入端固定连接,第一安装箱的内部设置有活动的小伞齿和大伞齿。本发明中,手动转动手动工具,手动工具带动小伞齿进行旋转,来驱动行星滚珠丝杠进行旋转,使行星滚珠螺母进行移动,在突然断电的时候,也可以通过这个手动调节的方式来把这个支撑块给收回去,使其车辆完成一个快速的撤离动作。
