Description

Technical Field

[0001] The utility model relates to the technical field of liquefied gas tanks, in particular to a portable device for pipeline anti-corrosion liquefied gas tanks. Background Art

[0002] A pipeline is a tubular structure used to transport liquids, gases or solid particles. It is widely used in industrial, construction and civil fields. Its uses include transporting tap water, sewage, oil, natural gas, chemicals, food and medicines. Some pipelines that are directly exposed to the outside for installation will produce corrosion on the surface under the influence of the natural environment for a long time. Therefore, anti-corrosion materials such as polyethylene are used to treat the pipeline surface and welds. The anti-corrosion process requires the use of anti-corrosion liquefied gas tanks to soften the pipeline anti-corrosion materials.

[0003] At present, in the process of anti-corrosion treatment of pipelines, traditional liquefied gas tanks are moved after being fixed by hand or straps in combination with a trolley. During the hand-carrying or bundling process, it takes a lot of time and physical strength to tie and fix the liquefied gas tank before moving it. If the straps are too tight, they may break, and if the straps are too loose, the liquefied gas tank may shake or fall off during the movement, which has certain defects.

[0004] Therefore, a convenient device for pipeline corrosion protection of liquefied gas tanks is proposed. Utility Model Content

[0009] The fixing assembly includes a base fixing device fixed on the supporting bottom plate, and the size of the base fixing device is designed according to the size of the current conventional liquefied gas tank base, so that the base fixing device can be sleeved in the liquefied gas tank base to fix the bottom of the liquefied gas tank;

When the first and second arc-shaped rods are extended outward, their front ends are closed to form a circular ring shape, thereby achieving the effect of fixing the liquefied gas tank.

[0042] The working principle of the portable device for pipeline corrosion protection of liquefied gas tanks proposed in this embodiment is as follows: when in use, the liquefied gas tank is placed on the supporting bottom plate 104 so that its base is sleeved on the side of the base fixture 201.
