Description
Technical field
The invention belongs to pressurized water reactor nuclear power station material-loading/unloading machine extension sleeve guiding clearance adjustment technology fields, and in particular to one
Kind fuel manipulator crane extension sleeve total travel running orbit accurately detects and adjusting process.
Background technology
Reactor core loading and unloading need in the underwater completion of 12 meters of depths, and fuel assembly heap in-core arrangement closely, reason
There was only about 1mm by gap, therefore it is required that fuel manipulator crane has very high positioning accuracy.
The component that fuel manipulator crane is directly connected with fuel assembly is inner sleeve, it is carried out by seven layers of directive wheel on outer sleeve
It is oriented to.The positioning accuracy of fuel assembly depends primarily upon the precision of inner sleeve, therefore the positioning accuracy of inner sleeve need to carry out accurately
Measurement, method traditional at present is that a trocar-like experimental rig is installed on fuel manipulator crane inner sleeve gripping apparatus, then will experiment
Paper is placed on inner sleeve lower limit height, repeatedly lifts inner sleeve in same position, test needle point is pricked out small on ph test paper ph
Hole site changes to judge the positioning accuracy of inner sleeve.This method can judge positioning accurate of the inner sleeve in lower limit well
Degree, but also have its limitation, i.e., it can not test the entire dynamic process of inner sleeve movement.
Due to the influence of many factors, there is swing to a certain degree in lifting process or turn in inner sleeve and fuel assembly
It is dynamic.Seven layers of directive wheel, which can realize inner sleeve, to be oriented to and positions, and is limited it and is rotated and swing.If directive wheel gap is excessive,
It then can not effectively limit the rotation and swing of fuel assembly；If directive wheel gap is too small, seven layers of directive wheel is difficult to ensure that
Gap uniformity is consistent, aggravates the swing of fuel assembly instead.
The rotation and swing of inner sleeve can cause the variation of loading and unloading process fuel assembly position, cause fuel assembly and phase
Adjacent component scrapes.The major way of fuel damage is pulled for grid spacer, and the immediate cause that grid spacer is pulled is just
It is the mutual scraping between fuel assembly.
To meet fuel assembly in the safety operation of reactor core, it is necessary to which inner sleeve total travel fortune can accurately be detected by inventing one kind
The technique of dynamic rail mark, and complete the accurate adjustment to extension sleeve guiding clearance.
The content of the invention
The defects of it is an object of the invention to be directed to the prior art, provides a kind of accurate detection inner sleeve total travel movement rail
The technique of mark and a set of directive wheel interval regulating process, for solve loading and unloading process fuel assembly position inaccurate and
