Landing wheel device of ground-effect wing ship

Abstract

The invention relates to the technical field of ship supporting structures, and particularly relates to a landing wheel device of a ground-effect wing ship. The device comprises a ship body. A front landing wheel module is fixedly connected to a bottom end surface of a front portion of the ship body, and rear landing wheel modules are symmetrically arranged on the left and right end surfaces of the rear portion of the ship body; the front landing wheel module comprises a cylinder body, and a telescopic pipe capable of sliding up and down is arranged in an inner cavity of the cylinder body; andeach ear landing wheel module comprises a mounting plate, the mounting plate is detachably connected to the ship body through a connecting piece, a servo motor is fixedly connected to the end surface, located on the inner side of the ship body, of the mounting plate, and a driving end of the servo motor is connected with a driving bevel gear. By using the landing wheels, tedious work of fixing the ground-effect wing ship and a large trailer is avoided, landing and launching are more convenient and faster, landing and launching time is shortened, and manpower and material resources are saved;and stability and safety of the ground-effect wing ship during flight and drainage navigation can be ensured.

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
