Problems solved by technology

This method of manual installation will make it impossible to intuitively and effectively control the installation quality of the positioning pins, and cannot ensure that the positioning pins are installed 100% successfully.
Moreover, since the positioning pin hole of the insert into which the positioning pin will be inserted is a blind hole, and the surface of the positioning pin after freezing will quickly form frost and thus block the exhaust groove, so it is easy to appear "air lock" when manually installing the positioning pin. ", "spring pin" phenomenon, which affects the installation quality of positioning pins, and there are certain hidden dangers in installation quality
In addition, liquid nitrogen reacts strongly when in contact with higher temperature objects, so splashing and frostbite accidents are prone to occur when manually installing positioning pins

Abstract

The invention aims at providing a reactor internal insert positioning pin automatic cool charge device. The device comprises a linear driving unit, and a guide unit, the linear driving unit comprisesa driving part and an ejector rod, the driving part is configured to drive the ejector rod to advance and retreat along the linear direction, the ejector rod is used for pushing and ejecting a positioning pin, the guide unit is used for supporting the positioning pin and allowing the positioning pin to slide, and is provided with a guide part, and the guide part is matched with the positioning pinto enable the positioning pin to slide in the linear direction, and the invention further provides a reactor internal insert positioning pin automatic cool charge method. According to the automatic cool charge device and method, manual operation of reactor internal insert positioning pin automatic cool charge is converted into mechanical automatic operation.

Description

Technical field [0001] The invention relates to an automatic cold mounting device for the positioning pin of a stack internal component insert, and also relates to an automatic cold mounting method for the positioning pin of a stack internal component insert, which is mainly applied to the cold mounting of the positioning pin of a nuclear power plant internal component insert. Background technique [0002] At present, in the field of nuclear power plant construction, the cold installation of the positioning pins of the internal components of the reactor is to soak the positioning pins in liquid nitrogen (-196℃) for a period of time, for example, about 30 minutes, and then remove the positioning pins from the liquid nitrogen, and then the operator wears them. Use a thick sheepskin glove to manually install the positioning pin. Using this method of manual installation will result in the inability to intuitively and effectively control the quality of the positioning pin installation...
