Amphibious ship

Abstract

An amphibious ship comprises a ship body, a propeller, a caterpillar band set mechanism, an air bag overturning and descending mechanism, a profiling wheel mechanism and a synchronous leg type mechanism, the climbing performance of the amphibious ship can be greatly improved through the four-caterpillar-band independent driving mode, and profiling wheels can assist four caterpillar bands in improving the obstacle crossing capacity of the amphibious ship. The synchronous leg type mechanism can be contracted on a ship body to facilitate transportation, landing work can be assisted after the synchronous leg type mechanism is unfolded, the air bag overturning and descending mechanism assists the amphibious ship to descend into a river through large-angle overturning of an air bag, and the four-crawler-belt mechanism, the profiling wheel mechanism, the synchronous leg type mechanism and the air bag overturning and descending mechanism are coordinated and matched together. And the amphibiousship can smoothly and stably finish the processes of going into a river and going ashore. The amphibious ship is compact and reasonable in structure and convenient to operate, land transportation running can be achieved, waterway navigation can also be achieved, and the amphibious transition operation efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to an amphibious ship. Background technique [0002] The operating environment of traditional ships is limited to water, does not have amphibious functions, and cannot walk on land, and does not have the function of going down the river and landing on its own. It is necessary to use trucks, cranes and other transfer equipment to realize the transfer between land and water, which is time-consuming and laborious. High labor costs and other issues. [0003] Most of the existing amphibious equipment is military products, such as amphibious tanks and amphibious transport vehicles, all of which adopt crawler walking mechanism, which has strong mobility and good passability, and has the ability to go down the river and land on its own. However, the above-mentioned amphibious equipment has higher requirements on bank slopes, and the applicable occasions are relatively narrow. Th...

AI Technical Summary

Problems solved by technology

Therefore, the existing amphibious ships have the following problems: the buoyancy of the hull of the amphibious ship entering the water is insufficient during the process of going down the river by itself, causing sinking and excessive inclination angle of entering the water; operations on land and shoals, and the operating environment is complicated; the distance between the front and rear tracks is large, and the driving performance is not good. High; when the amphibious ship climbs up to the bank or goes down the river by itself, due to the soft soil on the bank, the hull adhesion coefficient is low, and the track is easy to slip, which leads to the problem that it cannot go ashore smoothly or go down the river uncontrollably
