Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0022] The structure of a detachable internal component maintenance and repair bracket and its installation and debugging method will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1-5 As shown, the present invention is a working bracket used during the maintenance and repair of nuclear power plant reactor internals. It mainly includes: a stand 1, a lower adjustment pad 2, a platform frame 3, a positioning assembly I4, an upper adjustment nut 5, a positioning assembly II6, Upper adjustment pad 7, lower adjustment nut 8.

[0024] Wherein, the stand 1 includes a crossbeam 9, an I-beam 10, an auxiliary support 11, a positioning piece 12, and a flat plate 13. The I-beam 10 is located on both sides of the flat plate 13. 10 is vertical, the positioning planes 22 of the two positioning members 12 are equal in heig...

Abstract

The invention relates to a reactor internals maintaining tool for a nuclear power station, in particular to a working support for maintaining reactor internals of the nuclear power station. The support comprises a vertical frame and a platform frame, wherein the vertical frame and the platform frame are fixedly connected by a positioning assembly II, and a positioning assembly I is fixedly connected on the platform frame. The support has the advantages that (1) the whole support can be installed and dismantled conveniently and is convenient for remote transportation; (2) as all components of the whole frame are positioned by positioning pins and locked by bolts, and the position precisions are adjusted by gaskets during connection, the support has high positioning and adjustment precision and reliable and safe positioning; and (3) as the support is mainly in an I-steel frame structure, the support has good rigidity in the forced direction, simple overall structure and light weight.

Description

technical field [0001] The invention belongs to a nuclear power plant reactor internal component maintenance tool, and in particular relates to a working support used for maintenance and repair of the nuclear power plant reactor internal component. Background technique [0002] The reactor internal component maintenance and repair bracket refers to an operation support platform for transporting and transferring maintenance equipment between the water (boron-containing deionized water) and the underwater when the radiation supervision tube in the nuclear reactor is replaced. It is a key component in the underwater replacement of radiation supervision tubes in nuclear power plants. Since the irradiation supervisory tube is attached to the side wall of the hanging basket, the position is about 3 to 15 meters underwater. When replacing the supervisory irradiation tube, although the nuclear fuel has been removed, the hanging basket and the supervisory irradiation tube remain in p...
