Aircraft traction device

Abstract

The invention relates to the field of aircraft traction, and discloses an aircraft traction device. The aircraft traction device comprises a wheel holding mechanism and a bucket which are oppositely arranged and further comprises a sliding rail mechanism; the bucket is fixedly arranged on the sliding rail mechanism, and the wheel holding mechanism is connected with the sliding rail mechanism in a sliding manner through a vertical holding arm; and the bucket is connected with the wheel holding mechanism through an oil cylinder. According to the aircraft traction device, the sliding rail mechanism is arranged, the structure is simple, use is convenient, and the motion trail of the wheel holding mechanism is clear and definite; an H-shaped groove and a guide bearing are arranged, and the mechanism running stability is greatly improved; a lifting mechanism is arranged, so that load stress of the lifting mechanism is greatly increased, and reliability and safety of the device are improved; and a turning anti-draft mechanism is arranged, in the aircraft traction process, a pressing wheel, the bucket and the wheel holding mechanism are combined to effectively press wheels, the wheel are effectively prevented from shifting and loosening, and safety and stability during aircraft traction can be improved.

Description

technical field [0001] The invention relates to the field of aircraft towing, in particular to an aircraft towing device. Background technique [0002] The aircraft rodless electric traction device is a new type of aircraft push-pull traction device without a tow bar. Applicable to airports, hangars, factories and other occasions, it is the guarantee equipment for the user unit to tow and move the aircraft in a short distance. Especially the ideal traction support equipment for occasions requiring clean environment, low noise and limited fuel power. [0003] The traction device is one of the key components of the rodless traction device to realize the traction operation of the aircraft; but the structure of the traction device in the prior art is not perfect, and there is no protective measure for the possible deviation of the wheels, and the lifting mechanism generally adopts the inclined extension oil cylinder For lifting control, the load capacity is small, and there ar...
