Following Primary Reference Fig. 6 and 7 describes to measure using the survey tool of preferred embodiment according to the present utility model
The process of the centre-to-centre spacing of parallel pipe.It is noted that although described herein is the tool for the centre-to-centre spacing for measuring parallel pipe,
But survey tool according to the present utility model can be used for measuring the centre-to-centre spacing between other parallelpipeds, such as elliptical tube, side
Pipe etc., and section of two pipelines with same type is not required.
As shown in figs 6 and 7, it is measurement of the realization to the centre-to-centre spacing of parallel pipe C1, C2 of identical or different outer diameter, it is main
The center of circle O corresponding with each circular arc bayonet of vice card plate 400 of snap-gauge 3001- O5Distance d1 to snap-gauge center is identical, and main card plate
The distance d2 of datum mark 121 and vice card plate datum mark 221 to 100 graduation mark of scale is identical, to ensure when main card plate 300 and vice card
Plate 400 is positioned respectively with scale 100 and vernier 200 using main card plate positioning bolt 304 and vice card plate positioning bolt 404, and point
It is to survey two not with distance that after the first pipe C1 and the second pipe C2 clampings, vernier 200 is moved from zero graduation along scale 100
The centre-to-centre spacing of root parallel pipe C1, C2.
During practical measurement, it is specifically divided into following steps：
(1) preliminary examination card is carried out to the first pipe C1 to be measured and the second pipe C2 using any snap-gauge：According on snap-gauge
The bayonet internal diameter size of mark, obtains the outer diameter of tested pipe C1, C2, and determines that main card plate 300 and vice card plate 400 need to make
Bayonet；
(2) main card plate 300 and scale are fixed respectively using main card plate positioning bolt 304 and vice card plate positioning bolt 404
100th, the relative position of vice card plate 400 and vernier 200：Main card plate 300 is rotated in a circumferential direction and choosing by assembling bolt 302 around main card plate
Main card mouth 301 used is selected, after main card mouth 301 used is determined, installation main card plate positioning bolt 304, so as to ensure to justify
The arcuate midway point of arc bayonet is vertical with scale label line with the line of main card plate datum mark 121 and passes through zero graduation, by around pair
Snap-gauge assembling bolt 402 rotates in a circumferential direction vice card plate 400 and selects vice card mouth 401 used, when determining vice card mouth 401 used
Afterwards, installation vice card plate positioning bolt 404, so as to ensure the line of the arcuate midway point of circular arc bayonet and vice card plate datum mark 221
It is vertical with scale label line, if main card plate 300 is identical with the bayonet size used in vice card plate 400, as shown in fig. 6, surveying and being
The centre-to-centre spacing of outer diameter identical pipe C1, C2, otherwise as shown in fig. 7, surveying the centre-to-centre spacing of pipe C1, the C2 different for outer diameter；
(3) " zero " position is checked：Ensure when main card plate datum mark 121 and the coincidence of vice card plate datum mark 221, such as connect simultaneously
It closes when on same pipeline, " zero " scale of vernier 200 is aligned, and the tail scale of vernier 200 with " zero " scale of scale 100
Scale corresponding to scale 100 is aligned；
(4) main card mouth 301 used is preliminarily stuck on the first pipe C1；
(5) moving cursor 200 so that vice card plate 400 is moved near the second pipe C2；
(6) main card 301 circumferential position on the first pipe C1 of mouth is adjusted, until 401 and second pipe C2 of vice card mouth is pasted
It closes, and meets the clamping requirement of 301 and first pipe C1 of main card mouth, 401 and second pipe C2 of vice card mouth simultaneously；
(7) trip bolt 201 on vernier 200, position of the fixed vernier 200 on scale 100 are tightened；
(8) when main card plate 300 and vice card plate 400 respectively with two pipe C1, C2 clampings after, vernier 200 is from zero graduation edge
The distance that scale 100 moves is the centre-to-centre spacing of two surveyed pipes C1, C2, thus is read corresponding on scale 100 at this time
