Abstract

An overload protection device for a towbarless aircraft tow tractor comprises a buffering device and a control system; the buffering device comprises buffering hydraulic cylinders, a slide block, a slide block track and four connecting rods; the control system comprises a speed sensor, a hydraulic pressure sensor, an acceleration sensor, a position sensor, a controller, a power supply, an alarm system, a display system and an electric control regulating valve. The overload protection device for the towbarless aircraft tow tractor has the advantages that variable traction load under a special situation can be buffered by using the buffering hydraulic cylinders to protect an aircraft and the tractor against being destroyed, prevent overload and prevent the fatigue life of an aircraft landinggear structural part from being shortened; and therefore, the operation cost of an airline company is reduced; by using the four buffering hydraulic cylinders, the buffering force is stable, and comforts of a tractor driver and aircraft occupants can be improved; as the four buffering hydraulic cylinders are distributed in parallel, the operation performance of the tractor cannot be destroyed; and as the buffering forces of the four buffering hydraulic cylinders are large, the overload protection device for the towbarless aircraft tow tractor is especially suitable for objects with large masses such as the aircraft.

Description

Technical field [0001] The invention relates to a rodless aircraft towing vehicle overload protection device, belonging to the field of aircraft rodless towing overload protection. Background technique [0002] Nowadays, due to the increasing utilization of tractors, towing accidents are not uncommon, resulting in a lot of property losses. Excessive traction load is one of the main causes of traction accidents. For the aircraft operation department with zero tolerance for safety accidents, aircraft towing accidents are not allowed regardless of the cause. [0003] Aircraft ground towing is an important part of the guarantee of aircraft passing through stations. Aircraft tractors can be divided into rod-type aircraft tractors and rod-less aircraft tractors from the towing form. Most aircraft tractors with rods are connected to the aircraft's nose gear through hinged rigid tow rods, and some aircraft tow rods are equipped with buffer devices, and the tow rods are used to carry out ...
