Zusammenfassung: | The utility model relates to a precision alignment tank wagon truss type crane pipe detachment multi-airbag closed cover plate device which comprises two groups of airbags with different sizes. Portions capable of sealing tank openings are different in size, and the structure adapts to the tank openings with different diameters, is not limited by tank wagon specifications and is better in adaptability. By improving an airbag fixing structure, the airbags are more conveniently and rapidly detached and replaced, the structure is simpler, equipment cost is reduced, the truss type crane pipe detachment device precisely aligns three-dimensional movable crane pipes, oil-gas recovery quantity is further increased, the device can be used under various working conditions, gas recovery rate is effectively increased, and the device has the advantages of simple structure, convenience in operation, use safety, reliability and high recovery rate. |
