Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of special vehicle fault emergency evacuation and removal, and particularly relates to a civil aviation medium and heavy special vehicle removal equipment. BACKGROUND

[0002] Civil aviation special vehicles are key equipment for ensuring the operation of civil airports, including medium and heavy operation vehicles such as airplane towing vehicles, power supply vehicles, and lifting platform vehicles. In recent years, with the promotion of "oil to electricity" in the civil aviation industry, the proportion of new energy special vehicles has increased significantly, but problems such as battery failure and axle damage have caused vehicles to be unable to travel from time to time. Since these vehicles usually need to operate in a small space around the aircraft, a fault will directly affect the normal rate of flights and even cause safety risks. Currently, airports mainly rely on on-site maintenance or forced towing, but the former takes a long time and is prone to FOD risks in the flight area, and the latter can cause secondary damage to the vehicle equipment due to hard grinding of the ground.

[0003] Existing vehicle removal technology is mainly designed for ordinary road vehicles and cannot meet the special needs of civil aviation special vehicles. Traditional tow trucks cannot adapt to low chassis structures, and hard towing can easily damage the batteries and chassis systems of new energy vehicles; ordinary forklifts are too large to operate flexibly in the narrow space of the apron. More importantly, these devices lack the ability to stably lift and accurately position medium and heavy vehicles, resulting in low removal efficiency.

[0004] With the continuous growth of civil aviation transport volume, there is an increasing demand for quick and safe disposal of special vehicle faults at airports. There is an urgent need for a removal device designed specifically for civil aviation medium and heavy vehicles that can quickly evacuate a faulty vehicle while ensuring zero damage, thereby ensuring the safe operation of aircraft and the efficiency of airport operations. This need is particularly prominent in the context of the popularization of new energy special vehicles. UTILITY MODEL CONTENTS
