Description

Technical Field

[0001] The utility model relates to the technical field of oil loading and unloading devices, in particular to a loading and unloading pipeline for an oil transport vehicle. Background Art

[0002] As a kind of special-purpose vehicle, oil tanker bicycles are mainly used for medium- and short-distance oil transportation, such as transportation between special oil depots and users. The users are mainly special oil manufacturers and individual transportation customers who operate special oil. They need to load and unload oil on oil tanker bicycles. Therefore, the oil loading and unloading device used for oil tanker bicycles is an important automobile component.

[0003] The existing structure of the single-vehicle pump inlet and outlet interconnected with the loading and unloading pipeline is a single-layer type. Taking double-bin unloading as an example, two anti-bin cross-linking ball valves are arranged on the main loading and unloading pipeline, and two four-position three-way ball valves are arranged on the pump inlet and outlet pipelines. Two API oil unloading valves are connected in series behind the two four-position three-way ball valves, and an oil and gas recovery joint is arranged separately. In order to ensure both the operating space and the loading and unloading requirements, the length of the unloading box must be at least 1700mm and the depth must be at least 750mm, resulting in some compact chassis that cannot meet this unloading structure. In addition, in some loading and unloading sites without dedicated crane pipes, customers have to frequently disassemble and assemble the oil unloading reducer when using hoses for loading and unloading, which is inconvenient to operate and seriously affects work efficiency.
