Zusammenfassung:The utility model discloses a boiler roof tube hanging device capable of absorbing thermal expansion, belongs to the technical field of boilers, and aims to solve the problem that a boiler roof tube is damaged due to the fact that thermal expansion is caused after the boiler roof tube is heated and stress is generated. Comprising a plurality of hanging pipes, a plurality of adjustable screws and a hanging beam. The hanging beam comprises a groove beam with a lower opening, a plurality of steel bars are arranged at the bottom end of the groove beam in the length direction of the groove beam, a plurality of inverted-U-shaped hanging rings are arranged on the roof pipe, the steel bars penetrate through the hanging rings in a one-to-one correspondence mode, the hanging rings jointly slide in the groove beam along the groove width of the groove beam, and gaps are formed between the inner width of the hanging rings and the outer width of the steel bars. When the roof pipe is heated to expand and deform, the hanging
