Embodiment Construction

[0046] based on the following Figure 2 to Figure 11 , specifically explain the preferred embodiment of the present invention.

[0047] The invention provides an orthopedic device for correcting the roundness of a hanging basket cylinder, the device includes an orthopedic tool 1 and a supporting ring tool 2;

[0048] like figure 2 As shown, the orthopedic tooling 1 as a whole is a disc-shaped inner support, which includes a hydraulic jack 101 and several square support heads 103, and also includes a circular plug 102 arranged at the top of the hydraulic jack 101;

[0049] like image 3 As shown, the maximum output of the hydraulic jack (QF630T-20b) 101 is 600T;

[0050] The square support head 103 is detachable and can adjust the amount of ejection. The square support head 103 is used as the fulcrum of the orthopedic tooling 1 on the cylinder wall of the hanging basket cylinder during the correction;

[0051] In this embodiment, 10 square support heads 103 are distributed...

Abstract

The invention discloses a device and a method for correcting the roundness of a hanging basket barrel body. The device comprises a correction fixture and a supporting circular ring fixture, wherein the correction fixture comprises a hydraulic jack, a plurality of square supporting heads and a circular top arranged on the top of the hydraulic jack, wherein the supporting circular ring fixture comprises a plurality of layered supporting circular rings and connecting rods arranged among the supporting circular rings. The method comprises the following steps of: arranging a rough correction station, performing rough correction, and measuring the cylindricity of the barrel body by using a vertical trolley; arranging a fine correction station and performing fine correction; arranging the supporting circular ring fixture; and finally performing size stabilization thermal treatment. The device is extremely high in operability, convenient to execute and good in correction effect; a product can completely meet a design requirement; the correction working period is short; and a progress requirement can be met.

Description

technical field [0001] The invention relates to an orthopedic device and an orthopedic method for correcting the roundness of a hanging basket cylinder body of a pressurized water reactor internal component. Background technique [0002] As an important part of the reactor internals of the third-generation reactor, the basket cylinder is also the main load-bearing part of the reactor internals. All loads such as the swaying load of the hanging basket are transmitted to the supporting surface of the hanging basket of the pressure vessel by the flange of the upper cylinder of the hanging basket. [0003] like figure 1 As shown, the inner diameter of the upper cylinder of the third-generation reactor hanging basket is more than 3M, and the wall thickness is only about 50mm. There is 1 full-penetration circular seam and 1 full-penetration longitudinal seam. It is necessary to open holes and weld the outlet pipe, and the roundness requirements Extremely strict. The barrel of t...
