Description

Technical Field

[0001] This utility model relates to the field of liquefied natural gas technology, and more specifically, to an auxiliary moving mechanism for a liquefied natural gas storage tank. Background Technology

[0002] Liquefied natural gas (LNG), primarily composed of methane, is widely recognized as the cleanest fossil fuel on Earth. It is colorless, odorless, non-toxic, and non-corrosive. Its volume is approximately 1 / 625th that of the same amount of gaseous natural gas, and its mass is only about 45% of the same volume of water. Natural gas is mainly a mixture of low-molecular-weight alkanes and can be divided into dry and wet natural gas. Dry natural gas is primarily composed of methane, while wet natural gas, in addition to a large amount of methane, also contains significant amounts of ethane, propane, and butane. As is well known, LNG is mainly stored in storage tanks. Some LNG storage tanks contain large quantities or are very large, making transportation extremely inconvenient. This necessitates the use of specialized auxiliary moving vehicles for LNG storage tanks.

[0003] During the transportation of liquefied gas tanks, the tanks are usually moved onto a transport vehicle without any protective measures, which can cause collisions between the tanks. If they are not secured, there is a significant risk of accidents. Therefore, auxiliary securing is required, and the securing height needs to be adjusted accordingly. This application proposes an auxiliary moving mechanism for liquefied natural gas storage tanks to solve this problem.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
