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 object of the present invention is to provide an automatic cold-installation device for positioning pins of internal components, including: a linear drive unit, including a drive part and a push rod, the drive part is configured to drive the push rod to advance and retreat along a straight line, and the push rod is used to for pushing the positioning pin; and a guiding unit, used for supporting the positioning pin and allowing the positioning pin to slide, having a guide part, which cooperates with the positioning pin to make the positioning pin slide along a straight line. The invention also provides an automatic cold-installation method for the positioning pin of the insert block of the stack internal component. The automatic cold-installation device and method convert the manual operation of cold-installation of the positioning pin of the insert block of the stack internal component into a mechanical automatic operation.

Description

technical field [0001] The invention relates to an automatic cold-installation device for positioning pins of internal component inserts, and also relates to an automatic cold-installation method for positioning pins of internal component inserts. Background technique [0002] At present, in the field of nuclear power plant construction, the cold installation of the positioning pin of the internal component insert is to soak the positioning pin in liquid nitrogen (-196°C) for a period of time, such as about 30 minutes, and then take the positioning pin out of the liquid nitrogen, and then the operator wears it. Use thick sheepskin gloves to install the dowel manually. 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 ...
