Device for crossing deformation joint of gas overhead pipeline

The utility model discloses a device for a fuel gas overhead pipeline to cross a deformation joint, which comprises a first fuel gas pipeline material converter before the fuel gas overhead pipeline crosses the deformation joint, a second fuel gas pipeline material converter after the fuel gas overhead pipeline crosses the deformation joint, and a hose connected between the first fuel gas pipeline material converter and the second fuel gas pipeline material converter, the first fuel gas pipeline material converter is connected with a first overhead pipeline used for conveying fuel gas before crossing the deformation joint, and the second fuel gas pipeline material converter is connected with a second overhead pipeline used for conveying fuel gas after crossing the deformation joint. According to the crossing device provided by the utility model, the compensation amount of the gas pipeline is increased, so that the gas leakage accident caused by the fracture of the gas pipeline due to stretching due to the def
