Self-lifting vehicle ladder

Abstract

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.

Description

technical field [0001] The invention relates to a self-lifting car ladder. The device uses the power of the car's own wheel rotation to generate the lifting force, and can lift the vehicle without using external energy such as electricity. Occasions where the height of the vehicle is required. The invention relates to technical fields such as mechanical design. Background technique [0002] Parking difficulty is an increasingly serious social problem in modern society. The appearance of three-dimensional parking garage has solved the problem of parking difficulty to a certain extent. But most of today's three-dimensional garages need to cooperate with electric lifting devices to realize the lifting of vehicles. In the actual operation of the three-dimensional garage, it is found that the power consumption of the three-dimensional garage is very huge. The weight of a general vehicle is about one to two tons. One can imagine the energy consumed to lift such a large weight by...

AI Technical Summary

Problems solved by technology

Many communities are currently equipped with double-decker three-dimensional parking spaces, but due to the need for a huge amount of electricity to drive, the cost of using the upper parking spaces is very high, and many communities even abandon the upper parking spaces, which causes a great waste of parking resources.
