Description

Technical Field

[0001] This utility model relates to the field of protective fixtures for public bases, specifically a lifting and protective fixture for public bases. Background Technology

[0002] The common base is an integrated support platform for emergency diesel generator sets in nuclear power plants. The integrated structure of the common base can integrate the diesel engine, generator and auxiliary systems into a whole, improving seismic resistance and installation efficiency; through high-strength materials and vibration isolation systems, it ensures that the unit can operate reliably under extreme conditions.

[0003] During the manufacturing process of public bases, multiple turning operations are required. Traditional lifting methods suffer from insufficient side protection during these turning operations, making the side structures susceptible to deformation, dents, and tears due to localized stress concentration. This negatively impacts the appearance quality, equipment precision, and sealing of the public base. Lifting is an indispensable and crucial process in the manufacturing of public bases, acting as a vital link between different stages of the manufacturing process. Therefore, the importance of lifting for public base manufacturing is evident. Consequently, those skilled in the art have provided a lifting and protective fixture for public bases to address the problems mentioned in the background section. Summary of the Invention

[0008] Preferably, a limit rod is installed at one end of the round steel, and a limit groove is formed at the other end of the round steel.

[0009] Preferably, the limiting rod and the limiting groove are slidably engaged between adjacent round steel bars. By adjusting the distance between two adjacent round steel bars, the round steel bars can be used with common bases with different hole spacings when bolted to the common base, thus increasing the practicality of the round steel bars.
