Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated component processing, in particular to a hydraulic straightening device for prefabricated components of civil air defense projects. Background Art

[0002] Civil air defense projects, also known as civil air defense fortifications, refer to underground protective structures built to provide shelter for personnel and supplies, civil air defense command, and medical assistance during wartime. Prefabricated components are often used in their construction. These components are fastened together using rebar and other methods. This allows for rapid construction of civil air defense structures.

[0003] In the prior art, the metal structures in some prefabricated components may bend due to external forces during transportation, production and processing, such as steel bars. Before the prefabricated components are installed, they need to be straightened using a straightening device. However, the straightening process usually requires that the bent metal parts of the prefabricated components be placed on the straightening device for processing. Due to the large size and weight of the prefabricated components, this operation is not only manpower-consuming, but also has low straightening efficiency. The straightening device is also not adaptable enough and is not convenient to use. Utility Model Content
