Abstract

The invention discloses a disassembly and assembly tool for the manhole sealing gasket and the gasket pressing plate of a steam generator, including a grasping mechanism, an angle adjustment mechanism, a lifting mechanism and a supporting mechanism. The grasping mechanism includes a threaded casing, and the outer wall of the threaded casing There are 3 fastening parts, the ends of the fastening parts are connected with card slots, the angle adjustment mechanism includes a threaded shaft tube, and the outer wall of the threaded shaft tube is provided with 3 legs, of which 2 legs are provided with pins at the end, and the other There are connectors at the ends of the outriggers, and the lifting mechanism includes sleeves. There are 3 support rods on the outer wall of the sleeves. The ends of the support rods are connected with support tubes. It is located outside the threaded adjustment shaft tube, and the threaded adjustment shaft tube is connected with the connecting piece through the support rod. The lower end of the support tube is connected with the lifting guide tube, and the lower end of the casing tube is connected with the lifting rod. The lifting guide tube is connected with the moving mechanism. There is a problem of time-consuming and labor-intensive problems caused by manual support when the steam generator is overhauled.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for maintenance of steam generators in pressurized water reactor nuclear power plants (stations), in particular to a disassembly tool for manhole sealing gaskets and gasket pressing plates of steam generators. Background technique [0002] Domestic pressurized water reactor nuclear power plants (stations) need to open the primary and secondary side manhole covers of the steam generator, remove the sealing gasket and the gasket pressure plate, and allow personnel to enter the interior of the equipment for maintenance. However, in terms of structural design, the manhole sealing gasket and the gasket pressure plate are fixed on the equipment body by three fastening screws. Since there is no operating frame similar to the manhole cover that performs the function of rotating and closing, it must be installed during disassembly. Consider temporary support issues to avoid component fall damage. ...
