The invention discloses a self-lifting vehicle ladder. The self-lifting vehicle ladder is characterized in that two ends of a vehicle ladder lifting platform are provided with a pair of power rollers, the power rollers absorb power transmitted by driving wheels at the front part of a vehicle in the vehicle ladder to rotate, the rotating torque is transmitted to a worm gear through driving pinions, driving gearwheels, bevel pinions and big bevel gears, the torque is transmitted to climbing gears after the speed change of the worm gear, and the vertical movement of the vehicle ladder is realized due to the occlusion effect between the climbing gears and climbing racks. The self-lifting vehicle ladder is characterized in that rotatable cover plates are further assembled at the two ends of the lifting platform, reset springs are assembled on the cover plates, and the reset springs can enable the cover plates to be finally reset to the vertical state under the condition that external force is removed. The self-lifting vehicle ladder has the beneficial effects that the lifting force is generated by rotating power of the wheels of the vehicle, the vehicle can be lifted under the condition that external energy such as electric power is not needed, and the device is simple in structure, low in implementation cost and huge in application potential.
一种自举升车梯，其特征在于车梯举升平台两端分别有一对动力滚，动力滚吸收车梯内车辆前部驱动轮传来的动力发生转动，该转动力矩经过驱动小齿轮、驱动大齿轮、小伞齿轮、大伞齿轮传导给蜗杆齿轮，通过蜗杆齿轮变速后将力矩传导给爬升齿轮，由于爬升齿轮与爬升齿条之间的咬合作用实现车梯的上下移动。所述的自举升车梯，其特征在于举升平台两端还装配有一个可转动的盖板，盖板上装配有复位弹簧，该复位弹簧可使盖板在撤去外力的情况下最终复位到竖直状态。本发明的有益效果是采用汽车自身车轮转动的动力产生举升力，在不需要电力等外部能源的情况下即可实现对车辆的举升，装置结构简单、实现成本低、应用潜力巨大。
