Landing wheel device for wing-in-ground effect craft

Abstract

The invention relates to the technical field of ship support structures, in particular to a landing wheel device for a wing-in-ground effect ship. It includes a hull, the bottom end surface of the front part of the hull is fixedly connected to the front landing wheel module, and the left and right sides of the rear part of the hull are respectively symmetrically provided with the rear landing wheel module; the front landing wheel module includes a cylinder body, and the cylinder body A telescopic tube that can slide up and down is provided in the cavity; the rear landing wheel module includes a mounting plate, which is detachably connected to the hull through a connector, and the mounting plate is fixedly connected to the servo motor on the inner end surface of the hull. The driving end is connected with the driving bevel gear. The invention avoids the cumbersome work of fixing the wing-in-ground effect ship and the large trailer by using the landing wheel, makes landing and launching more convenient and fast, shortens the time of landing and launching, and saves manpower and material resources; Stability and safety when sailing in displacement.

Description

technical field [0001] The invention relates to the technical field of ship support structures, in particular to a landing wheel device for a wing-in-ground effect ship. Background technique [0002] The wing-in-ground effect ship has various motion states such as water surface drainage navigation, ground-effect area flight and aircraft flight, and its main movement area is the water surface and the low-altitude area above the water. However, due to the needs of loading, overhaul and maintenance, the wing-in-ground effect ship often needs Landing and entering the water. When the WIG without landing device lands, the trailer is first placed in the shallow water area of ​​the shore, then the WIG is docked on the trailer and fixed, and finally the trailer is pulled to land the WIG. The fixing work of the wing-in-ground effect boat and the trailer is carried out in shallow water areas. When the water surface is rough, the fixing work is very difficult and requires a lot of time...

AI Technical Summary

Problems solved by technology

However, the front wheels are not controlled in the flying state, the side of the tires facing the wind will bring resistance to the flight, and the front wheels will rotate against the wind, which will also adversely affect the flight stability of the wing-in-ground effect craft.

In addition, the specific implementation of rear wheel retraction is not disclosed in this patent

[0004] The invention patent with the publication number CN110127021A discloses a landing gear of an airship. When in flight, the landing gear is retracted into the body of the airship to reduce flight resistance. However, this landing gear is not suitable for amphibious wing-in-ground craft

If the landing wheel is received at the lower part of the hull of the wing-in-ground effect ship, when the landing wheel is supported in the water, the water entering the bottom of the hull will bring great safety hazards
