[0016] In order to further understand the invention content, characteristics and effects of the utility model, the following examples are exemplified, and the detailed description is as follows in cooperation with the drawings:

[0017] Please refer to Figures 1-4 A chain type overturning device for circumferential overturning of a cylindrical structure, comprising a plurality of rollers 3, two adjacent rollers 3 are connected through a wheel frame, the wheel frame is provided with chain plates 5 on both sides, the two ends of the two chain plates 5 are respectively hinged to the corresponding rollers 3 through pin shafts 6, the two sides of the roller at the end of the device are connected with the end 1 through the wheel plate 2, the wheel plate 2 is vertically fixedly connected with the end 1 and is hinged to the roller 3, and the end 1 is provided with a lifting hole.

[0018] The more preferred scheme of the embodiment is as follows:

[0019] The end is an A type end.

[0020] The roller 3 adopts a grooved wheel, a plurality of grooves are formed in the surface, rubber protection rings 4 with protruding notches are arranged in the grooves, the rubber protection rings 4 are used for increasing friction and protecting the cylindrical structure.

[0021] The wheel frame is welded by flat steel, two connecting plates are welded between the two chain plates 5, and the structure is simple and reliable.
