Both personnel easy to operation carried out dismounting adjustment operation to laser tracker, and to all upper layer auxiliary base points and can own
Lower layer's auxiliary base point keeps the angle of depression to measure, and improves convenience of the later stage to auxiliary base click-through row data acquisition.
In conjunction with shown in Fig. 2, in the present embodiment, installation fixation is carried out to laser tracker 2 by measurement bay 1.Wherein, it surveys
Amount frame 1 is long rod shaped structure, and one end is connect as fixing end with reactor building heap chamber cylinder 3, and the other end is used as installation end
In installation and fixed laser tracker 2, and installation end is stretched into the horizontal direction in reactor building heap chamber cylinder 3, is formed outstanding
Arm girder construction.At this point, can be kept away completely in the position relationship of vertical direction by adjusting between measurement bay and upper layer datum mark
Exempt from measurement interference of the measurement bay itself between laser tracker and datum mark, to ensure laser tracker and all auxiliary bases
It is visual between on schedule, ensure that realization accurately measures each auxiliary base point.
Preferably, between measurement bay 1 and reactor building heap chamber cylinder 3 using rotation connection, in order to laser with
The spatial position of track instrument 2 is adjusted.In the present embodiment, pass through shaft between measurement bay 1 and reactor building heap chamber cylinder 3
4 connection forms the rotation in horizontal plane.Wherein, it is equipped with vertically perforative through-hole 11 in the fixing end of measurement bay 1,
The mounting hole 31 being vertically arranged is equipped on+28.0 meters of platforms of reactor building heap chamber cylinder 3 simultaneously, if this is flat
Having similar mounting hole at platform then can directly borrow, and the lower end of shaft 4 inserts after passing through through-hole 11 to mounting hole 31 at this time
In, to complete to horizontally rotate connection between measurement bay 1 and reactor building heap chamber cylinder 3.In this way, carrying out in-pile component
Hoisting process in, you can laser tracker is carried out by the rotational translation in horizontal plane by rotation measuring frame, to avoid pair
The influence of lifting ensures being smoothed out for lifting operation, while improving the protection to laser tracker.
It is further preferred that the fixing end in measurement bay 1 is additionally provided with a lock-screw 5.Lock-screw 5 is in the horizontal direction
Setting, and front end is extended to through the hole wall of through-hole 11 in through-hole 11, to which countershaft 4 and measurement bay 1 carry out relative position pass
System is locked.
Meanwhile being equipped with multiple along the circumferential direction uniformly distributed flange holes 12, and flange hole 12 in the installation end of measurement bay 1

It, can by will be transferred in the auxiliary coordinates to the positioning requirements of pressure container flange face benchmark in in-pile component installation process
To carry out the positioning measurement of in-pile component installation directly in the auxiliary coordinates, to avoid carrying out every time in the prior art
It is required for carrying out flange face the repetitive operation of feature points generation when the installation positioning measurement of in-pile component, improve to in-pile component
The operating efficiency of positioning measurement, and all standing by the auxiliary coordinates to in-pile component feature point are carried out, can be solved
Certainly due to causing to measure there are larger difference in height between Partial Feature point and flange face benchmark in the existing coordinate system of workshop
The problem of accuracy decline, so as to improve the precision to in-pile component positioning measurement.
In addition, the foundation of auxiliary coordinates is completed, in the aligner measurements for carrying out follow-up in-pile component installation, if
The spatial position of laser tracker adjusts, such as issues the pivot offset of raw horizontal direction in the drive of measurement bay, at this time
Before the positioning measurement for carrying out in-pile component, need to carry out once adjusting again to measure, i.e., it is auxiliary to upper layer auxiliary base point and lower layer
It helps datum mark to measure acquisition, and measurement data is placed directly in SA softwares and is fitted processing, to auxiliary base point
Precision is detected, and ensures the measurement accuracy after the adjustment of laser tracker position.
In addition, the installation with in-pile component from bottom to top successively, the installation site of lower layer's auxiliary base point can carry out
Upward floating adjustment, to be adjusted to auxiliary coordinates.At this point, installing one again in existing auxiliary coordinates first
Layer auxiliary base point, wherein the auxiliary base point are located between upper layer auxiliary base point and lower layer's auxiliary base point；Then existing
Fitting is measured to the auxiliary base point newly installed in some auxiliary coordinates, core is carried out to the precision of three layers of auxiliary base point
It is right；Then after the installation site precision of newly installation auxiliary base point meets the requirements, lower layer's auxiliary base point is removed, to by elder generation
The auxiliary base point of installation substitutes original lower layer's auxiliary base point, completes the adjustment to auxiliary base point.By to assisting base
The floating adjustment of position on schedule, can both cover lower layer's auxiliary base point to avoid the in-pile component that installation is completed, and shadow
Ring measurement of the laser tracker to the datum mark, and by the change with in-pile component installation region to auxiliary coordinates into
Row adjustment can be always ensured that the auxiliary coordinates install in-pile component the precision of positioning measurement.
