Bionic airplane wheel chock

Abstract

The invention discloses a bionic airplane wheel chock. The wheel chock comprises a wheel chock body and two supporting feet, the wheel chock body comprises a front baffle, a front bottom plate, two side baffles and a rear baffle, the rear baffle is of a curved surface structure with the radius larger than that of an airplane wheel, and protruding transverse anti-skid strips are arranged at the upper end and the lower end of the curved surface respectively; and the supporting feet are of a goat foot and foot imitating structure and are connected with the wheel chock front bottom plate, the supporting feet are of a Y-shaped structure and separately comprise a round pipe, toes, annular reinforcing ribs and hoof boxes, the toes are symmetrically arranged on the two sides of the round pipe, the annular reinforcing ribs are arranged in the middles of the toes, the hoof boxes are arranged at the lower ends of the toes, and the hoof boxes are characterized in that the heels are wide and smooth, the tops are narrow and sharp, and the two toes are symmetrically separated towards two sides. The blocking force of the wheel chock is larger, an airplane in a hot refueling state can be kept static, displacement is avoided, and damage to the ground is avoided.

Description

technical field [0001] The invention relates to an aircraft wheel chock, in particular to an aircraft wheel chock imitating a goat's foot. Background technique [0002] Typically, chocks are placed in front of and behind the wheels to prevent the aircraft from moving during maintenance operations such as parking the aircraft and changing wheels. Traditional wheel chocks have low resistance and are only suitable for aircrafts parked. They are easy to damage the ground and difficult to take out. With the changes in combat training requirements, in order to shorten the preparation time for the aircraft to dispatch again, the aircraft will adopt thermal refueling technology, so that the aircraft can be refueled and mounted weapons without stopping on the ground. The new wheel chocks must not only meet the blocking function when the aircraft is parked and using the brakes, but also meet the blocking function when the aircraft is hot and refueling. [0003] The traditional wheel...

AI Technical Summary

Problems solved by technology

[0004] 1) It is not suitable for the working condition of hot refueling and no brakes. When the aircraft is hot refueling and no brakes are used, the thrust of the aircraft is large, and the blocking effect of the currently used wheel chocks is not good, and it cannot maintain the stable parking of the aircraft in the hot refueling state;

[0005] 2) The currently used wheel chock is vulnerable to the ground, and its contact part with the ground is pointed. After being pressed, the pointed part penetrates into the ground, which is easy to damage the airport ground.
