Embodiment
The utility model is further described below in conjunction with the accompanying drawings；
In the accompanying drawings：Weld reinforcement and mother metal edge amount of contraction special gauge are detected, after the sanding and polishing of surface
The detection of weld reinforcement and mother metal edge amount of contraction；Including dial gauge 1；Also include positioning mobile jib 2；Described dial gauge 1 passes through
Clamping screw 3 is connected to positioning mobile jib 2 end, easy installation and removal；Described positioning mobile jib 2 is by rectangular blocks 201 and connection
Circular cone 202 in the bottom of rectangular blocks 201 forms；The length direction of described rectangular blocks 201, one end are protruded in circular cone
Outside 202, be advantageous to that dial gauge 1 is installed；Several support frames 4 are provided with the described outer wall of positioning mobile jib 2；Described support
The quantity of frame 4 is two, and the connected mode between positioning mobile jib 2 is welding or bolt connection；Described positioning mobile jib 2 and branch
Graduated scale 5 is provided between support 4；In gauge rod on one side end face of the length direction of described graduated scale 5 and dial gauge 1
Heart line 6 flushes, and the other end flushes with positioning mobile jib 2, is easy to control mobile size, and is advantageous to graduated scale 5 positioning of itself；
Described graduated scale 5 is bonded on the inwall of support frame 4, and bonding will not damage graduated scale 5；The height gauge of described positioning mobile jib 2
Size B on very little A≤support frame 4, it is easy to position mobile jib 2 and support frame 4 forms three-point fix in nuclear island main pipe 101, surely
It is qualitative good；Described support frame 4 is " Π " shape structure, and two leg bottoms are provided with arc surface 401, is easy to and nuclear island main pipe
101 surfaces are bonded；During actual use, dial gauge 1 is installed in rectangular blocks 201 first, is locked, entered by clamping screw 3
One step selects datum mark 102 in nuclear island main pipe 101, determines that datum mark 102 arrives the size 103 at the edge of nuclear island main pipe 101,
See Fig. 8, at datum mark 102, calibration dial gauge 1 arrives zero-bit；Further shift position, by the corresponding size line on graduated scale 5,
Alignd with datum mark 102, for example when size 103 is 100mm, the graticule 10 on graduated scale 5 aligns with datum mark 102, due to
One side end face of the length direction of described graduated scale 5 flushes with the center line 6 of the gauge rod on dial gauge 1, so the institute of dial gauge 1
Position be exactly the position at the edge of nuclear island main pipe 101, therefore can measure, the amount of contraction at the edge of nuclear island main pipe 101,
