Abstract

The invention belongs to the technical field of nuclear power, and particularly relates to drawing type automatic pipe plugging equipment. In the plug connecting assembly, the output end of the gearbox is connected with the mandrel, and the input end of the gearbox is connected with the motor; the gearbox is fixedly connected with the output end of the first air cylinder, a first guide hole is formed in the gearbox in the axial direction, the first guide rod penetrates through the first guide hole, and the first air cylinder can drive the gearbox to move up and down along the first guide rod. Under the condition that the first air cylinder drives the mandrel to move upwards to be inserted into the plug expansion block, the motor is controlled to transmit movement through the gearbox to drive the mandrel to rotate forwards, and meshing of the upper end of the mandrel and the plug expansion block is completed. Through air supply, plug filling, plug connection and plug feeding actions can be realized.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a pulling-type automatic pipe plugging device. Background technique [0002] The heat transfer tubes in the steam generator of the nuclear power plant will be damaged with the operation of the unit. The easiest way is to block the heat transfer tubes, that is, to repair the tubes. The pull-type plugging is a technology that puts the pull-type plug into the heat transfer tube, and pulls the expansion block in the plug to make the plug expand and tighten on the heat transfer tube. [0003] "Hualong One" is an advanced mega-kilowatt pressurized water reactor nuclear power technology jointly developed by China National Nuclear Corporation and China General Nuclear Power Group. However, there is currently no mechanical plugging technology for heat transfer tubes that can be used in Hualong No. 1 steam generator in China. Contents of the invention [0004] In orde...
