[0002] Galvanized pipe is a kind of corrosion-resistant pipe, and has been widely used in the field of construction, machinery and other fields. However, the surface of the galvanized pipe may be deformed (i.e., a depression is generated) due to external forces during production, transportation and use.

[0003] In the prior art, the depression of the galvanized pipe is usually reset by lifting the depression with a lifting device. However, the lifting device can only lift the depression of the galvanized pipe to complete the reset process. On the other hand, some existing deformation reset devices lack effective reset detection equipment, resulting in poor deformation reset effect after the galvanized pipe is reset, and the reset position is more likely to deform during subsequent use.

[0005] The two ends of the support arm are hingedly connected to the main arm and the sliding member. When the deformation reset detection mechanism moves in the pipe to be reset, the roller abuts against the inner wall of the reset galvanized pipe.

[0006] The distance sensor determines the depression of the inner wall of the galvanized pipe by obtaining the distance between the sliding member and the distance sensor, and detects the deformation reset degree of the galvanized pipe.

[0007] In some embodiments, the fixed seat has an L-shaped structure, which includes a hinged part hingedly connected to the main arm, and a sliding part arranged horizontally.

[0008] The sliding part is provided with a sliding groove matched with the sliding member, and the sliding groove is slidingly connected to the sliding member.

[0009] In some embodiments, a support spring is further provided between the sliding member and the fixed seat, and the direction of the support spring is parallel to the sliding direction of the sliding member. The two ends of the support spring are connected to the sliding member and the fixed seat, respectively.

[0010] The utility model provides a kind of galvanized pipe shape change reset device, including the shape change reset detection mechanism of any one described in above scheme.

[0011] In some embodiments, the galvanized pipe shape change reset device further comprises: a cylindrical shell, wherein the shape change reset detection mechanism is distributed circumferentially on the shell.

[0012] By adopting the above technical scheme, the utility model mainly has the following technical effects:

[0013] The reset degree of the pipe to be reset after reset is detected by the shape change detection mechanism, and the reset process is performed again when the reset requirement is not met, thereby enhancing the reset effect of the concave portion of the pipe to be reset.
