Aircraft traction auxiliary device and use method

Abstract

The invention relates to the technical field of airport ground special equipment, and discloses an aircraft traction auxiliary device and a using method, the aircraft traction auxiliary device comprises a movable T-shaped base platform used for supporting an auxiliary lifting platform and a main lifting platform; the auxiliary lifting platform is used for realizing vertical lifting of an airplane wheel axle; the main lifting platform can move in the axis direction of the airplane wheel, and left and right tires of the front airplane wheel of the airplane can be independently and vertically lifted. And the automatic control platform is used for automatically controlling the whole device. For traction work of small and medium-sized aircrafts, airplane wheel lifting and traction work can be achieved, and resource waste caused by the fact that a traditional tractor is taken out is avoided; compared with a traditional tractor, the tractor can adapt to the working condition of tire burst of single-side airplane wheels through the airplane wheel lifting plate frames independently controlled on the two sides, and is practical and suitable for wide application and popularization.

Description

technical field [0001] The invention belongs to the technical field of airport ground special equipment, and in particular relates to an aircraft traction auxiliary device and a method for using the same. Background technique [0002] The rapid development of the civil aviation transportation industry has led to a substantial increase in the number of operating aircraft, and the increase in the number of routes and flight density has put forward higher requirements for airport ground support facilities, especially in the case of small emergencies with a high number of occurrences, the runway is occupied It will seriously affect the flight plans of other flights. How to quickly respond to the occurrence of small accidents and quickly and efficiently transfer the faulty aircraft plays a key role in ensuring the ground order and normal operation of the airport. At present, for accidents such as small and medium-sized aircraft running out of the runway and the landing gear is br...

AI Technical Summary

Problems solved by technology

However, the cost of aircraft tractors is high, about 1 million per unit. In 2008, the rodless aircraft tractor introduced by my country for the Airbus-A380 was even as high as 11 million per unit. With the increase of flights, the scheduling of aircraft tractors is tight. If Long-term arrangements for lifting and towing small aircraft, resulting in a waste of resources; the operation of the tractor requires full-time maintenance personnel, which requires a high level of operation; the wheel holding mechanism of the aircraft tractor has a small space, and can only lift and tow the wheels There is no room for further maintenance of tires, and special aircraft wheel maintenance lifting equipment is used, which leads to complicated procedures and waste of resources for some simple wheel maintenance work

[0003] Secondly, the aircraft tractor has a relatively large lifting capacity. For the ground transfer of small and medium-sized aircraft, the use of aircraft tractors has the problem of waste of resources, which makes the work arrangement for the traction and transfer of medium and large aircraft more compact, and the time and space fault tolerance rate is reduced. The scheduling of ground support equipment at airports with multiple aircraft types, flights and high passenger flow density is not conducive to the improvement of airport operation efficiency during periods of heavy workload;

[0004] Thirdly, for the wheel maintenance needs of small and medium-sized aircraft, it is not convenient to use a fixed lifting device to transfer the position of the aircraft, and the aircraft tractor is limited by its working range because the space around the wheel is greatly reduced after lifting the wheel. Facilitate wheel maintenance operations

An aircraft automatic lifting device proposed in CN202110942096.3 has the characteristics of simple operation, low cost, and convenient wheel maintenance. However, this limits its scope of use to a certain extent; and the entire lifting plate frame is a cantilever beam structure, the stress is easy to concentrate during the lifting process, and the strength requirements for the lifting mechanism are relatively high, which increases the difficulty and cost of manufacturing
