Device for a target in place for nuclear steam generator catch water

The utility model discloses a device for a target in place for nuclear steam generator catch water is through setting up the staple bolt, lower staple bolt, a pair of first cushion and a pair of roller subassembly, the utility model discloses a go up the staple bolt, lower staple bolt is fixed with a whirlwind section of thick bamboo, not only further strengthens catch water from structural, compensaties the shortcoming that catch water structural stiffness is poor, satisfies the dress in narrow and small space moreover, unloads the requirement, adopt roller and roller lid, the rigidity and the rollability of roller are better, both can bear whole catch water's weight, can reduce the friction of removing in-process and shells inner wall again, reduce the resistance, adopt the cushion to adjust catch water and upper portion shells inner wall's concentricity. The utility model discloses convenient operation can drive catch water circumference and axial displacement in a flexible way, and can adjust catch water and shells inner wall's distance, guarantees catch water and upper portion shells inner wall's concentricity
