Problems solved by technology

However, the clamping-lifting device commonly used at present has the following problems: the lifting mechanism adopts a single-rod spherical joint for lifting, and it is easy to cause the vertical line of the nose landing gear of the aircraft to misalign with the center of gravity during the lifting process, resulting in additional torque, thus It affects its s

Abstract

The invention discloses a rodless aircraft tractor clamping and lifting device which comprises a base, two hinge heads, two rotary rear baffles, two rotary rear baffle hydraulic cylinder components, a plurality of cylindrical pins, a lifting bearing bucket, two lifting bearing bucket hydraulic cylinder components, two lifting bearing bucket auxiliary hydraulic cylinder components, two compressing supports and two compressing support hydraulic cylinder components. According to the rodless aircraft tractor clamping and lifting device, the number of the degrees of freedom of a mechanism is changed through the limitation of the stroke of the hydraulic cylinder components, and therefore the lifting bearing bucket is changed to rotate in a vertical plane from the horizontal motion, intermediate links are effectively reduced, safety can be improved, the complexity degree of a control system can be lowered, meanwhile, the safety can be improved, hydraulic loops can be reduced, a power device can be arranged in a centralized mode, and the device has the advantages of being reasonable in structural design, convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of airport ground special equipment, and in particular relates to a clamping-lifting device for a rodless aircraft tractor. Background technique [0002] Aircraft tractor is a support equipment used to tow aircraft on the ground of the airport. It has the characteristics of low body, heavy vehicle weight and large traction force. According to its structure, it is divided into rod tractor and rodless tractor. Among them, due to its small size, light weight, small operating area, and no need to replace the tow bar, the rodless tractor has gradually become the main force of aircraft tractors, and has become a hot spot in the development of aircraft ground support equipment in the world. One of the key points for judging the quality of the rodless aircraft tractor is the quality of its docking part with the aircraft, that is, the quality of the clamping-lifting device. The clamping-lifting device on the rodles...
