Embodiment

[0023] like figure 1 As shown, the present invention is a device for assembling and welding the radiation supervisory tube, comprising a base 5, the base 5 is made of cast iron, its cross section is I-shaped, and a concave hole is arranged in the middle of the base. The connector 12 of the groove is provided with a support seat 11 in the connector 12, and the support seat is provided with two slopes to form a V-shaped groove. Two neck support blocks 10 on the top, a limit reference block 8 is also provided between the support base 11 and the neck support block 10, the limit reference block 8 is used as a reference for defining length and height, and it is compatible with the neck support The block 10 and the base 5 are formed with an integrated structure, and also include a four-petal centering member 1 that wraps the radiation supervision tube 9. After the four-petal centering member 1 is wrapped on the outside of the radiation supervision tube 9, one end is fixed at the bott...

Abstract

The invention discloses a device for assembling and welding an irradiation monitoring pipe. The device is characterized in that a supporting seat provided with a V-shaped groove is arranged on a base, wherein an annular rolling seat is arranged on the supporting seat; two neck part supporting blocks, which are positioned at two sides of the supporting seat and symmetrically distributed on one straight line, are arranged on the base; a limiting datum block is arranged between the supporting seat and each neck part supporting block. The device further comprises four centering component pieces which wrap the irradiation monitoring pipe, wherein the four centering component pieces wrap the outer side of the irradiation monitoring pipe, and then one end of each centering component piece is fixed into a rolling assembly on the supporting seat while the other end of the each centering component piece is positioned on the corresponding limiting datum block. According to the device, the tool design is high in compatibility, and the assembling process and the welding process of the radiation monitoring pipe can be synchronously carried out; the cooling effect of a weld joint in the process of welding the radiation monitoring pipe can be effectively ensured, so that the weld joint can be prevented from collapsing; the linearity and coaxiality of the whole radiation monitoring pipe can be effectively ensured; the device can be overturned in 360 degrees, so that the welding efficiency can be effectively improved; the device is convenient to dismount.

Description

technical field [0001] The invention relates to the field of assembling and welding of radiation supervision tubes, in particular to a device for assembling and welding of radiation supervision tubes. Background technique [0002] The radiation monitoring tube is an important part for monitoring the radiation effect of materials on the reactor pressure vessel during the life of the nuclear reactor. It is necessary to obtain the radiation environment data of the reactor pressure vessel, the degree of embrittlement of the material and its development trend, and to evaluate the integrity of the reactor pressure vessel. It is of great significance to revise the operating parameters of the reactor and finally ensure the safe operation of the reactor. Each irradiation supervision tube is mainly composed of a top plug, a bottom plug, two half-slot shells, several temperature detectors and dose detectors, various tensile and impact mechanical samples. The radiation supervision tube...
