Abstract

The invention discloses a nuclear power pipeline branch pipe opening welding mould and mainly relates to the field of welding moulds. The welding mould comprises an outer ring, an inner disc, supporting rods, an arc-shaped base plate and a pressing plate. The outer ring is provided with multiple through holes. A fixing column is arranged on the outer surface of the outer ring. A locating hole is formed in the fixing column. The inner disc is arranged in the outer ring. One side face of the inner disc is provided with a plane thread structure. The ends of the multiple supporting rods penetratethrough the through holes and are installed on plane threads correspondingly and connected with a plane thread structure in a transmission manner. The arc-shaped base plate is provided with a via hole. The diameter of the pressing plate is larger than the hole diameter of branch pipe openings. The pressing plate is provided with a fixing rod. The tail end of the fixing rod penetrates through the via hole and is fixed to the locating hole, and the pressing plate presses the ends faces of the branch pipe openings. The welding mould has the beneficial effects that under the circumstance of not adjusting rotating of nuclear power pipelines, two branch pipe openings can be welded, the preparation work load before whole welding is small, the difficulty is low, and the welding efficiency is improved greatly.

Description

Technical field [0001] The invention relates to the field of welding molds, in particular to a welding mold for branch nozzles of nuclear power pipelines. Background technique [0002] As attached in the description Figure 5 As shown, there are two branch nozzles on the nuclear power main pipeline, the first branch nozzle is on the side of the nuclear power main pipeline, and the second branch nozzle is on the oblique side upward of the nuclear power main pipeline. The welding work of these two branch pipes is extremely demanding. The existing method is to weld each branch pipe one by one, with the nozzle welding hole on the nuclear power main pipeline facing upwards, and then install a supporting device inside the nuclear power main pipeline , The branch pipe to be welded is supported from the inside of the nuclear power main pipeline, and then the welding work is carried out. When the second branch pipe is welded, the rotating nuclear power main pipeline has to be re-adjusted ...
