置を測定すればよい。The spherical inner race 51 has a spherical outer race 5 fitted to the spherical portion of the spherical inner race 51.
2 is rotatably and tiltably provided, and the spherical outer race 52 is supported by a disk-shaped spacer 49.
The spacer 49 is loosely fitted to the inner peripheral portion of the protective cylinder 11 so that it can slide up and down on the inner surface of the protective cylinder 11.
As a result, the upper end of the detection rod 3 is supported by the spherical bearing portion 50 so as to be rotatable, tiltable, and vertically movable.
Therefore, when the conduit 1 is laterally displaced, as shown in FIG. 12, the detection rod 3 can be inclined by the angle α, and at this time, if the depth of the universal joint portion 30 is L, the conduit 1 is displaced. Since the length S is Ltan α, the deviation S can be calculated by measuring the angle α. Since the angle α is minute, the subsidence amount D of the conduit 1 can be measured by measuring the tip position of the detection rod 3 as in the conventional case.

The X level gauge 77 is provided in the cavity in the main body 79 so that the lever 83, which is a pendulum suspended by the shaft 86, and the weight 84 vibrate with appropriate damping characteristics damped by the silicon oil 89. A ferrite core 81 is horizontally supported below the lever 83, and the ferrite core 81 is located inside the coil 82 of the differential transformer 80. If the output of the differential transformer 80 is set to 0 when the main body 79 is placed horizontally, a slight inclination of the X level gauge 77 can be measured as the output of the differential transformer 80. Differential transformer 8
Since 0 is easily obtained with an accuracy of about 1 micron, if the length of the lever 83 is 10 centimeters, the minimum detection angle is 1/100000 radians = 0.00057 degrees, and as a result, a slight deviation of the conduit 1 occurs. Can be measured accurately.
The Y level gauge 78 is also the X level gauge 77 described above.

As shown in the figure, since the X level gauge 77 and the Y level gauge 78 are provided so that the measurement angle directions are orthogonal to each other, the inclination of the inclinometer 70 is the output of the X level gauge 77 that corresponds to the X, Y level gauge 78. Assuming that the output of Y is Y, the inclination is √ (X 2 + Y 2 ) which is the vector sum of X and Y, and the inclination direction θ is atan Y / X. (Atan is Arctangent)

The alternating current of about kilohertz drives the differential transformer 80 in the X level gauge 77 and the Y level gauge 78, and outputs X and Y according to the position of the ferrite core 81.
Is obtained. The outputs X and Y are amplified and the arithmetic circuit 91
At √ (X 2 + Y 2 ), which is the vector sum of X and Y, and atan Y / X, which is the inclination direction θ, are calculated. Therefore, referring to FIG. 12, the deviation S of the conduit 1 is
In the horizontal direction, it is obtained by Ltan [√ (X 2 + Y 2 )], and its direction θ is obtained by atan Y / X. Also,
The vertical displacement of the conduit 1 is obtained with a displacement amount of D. As a result, a three-dimensional offset amount of conduit 1 can be easily obtained.
