There is a risk of becoming. On the other hand, the electric inspection vehicle is provided with a deviation measuring device, and the vehicle is run periodically or when necessary to measure the deviation amount and managed. Since the measurement of the wear amount and height of the trolley wire 1 is also important, the deviation measuring device can be used for both wear measurement and the height measuring device is provided separately.

42 (not shown) is also horizontal, and the deviation reference line C ′ is vertical. On the other hand, the swaying state of the vehicle body 41 is somewhat complicated, but for the sake of simple consideration, the vehicle body 41 may rotate in the left-right direction with the horizontal center point O of the floor surface 411 as the center of rotation. As a result, the vehicle body 41 tilts to the left as shown in the figure at a certain moment, and therefore the measurement reference line K of the deviation measuring device 6 tilts to the left with respect to the deviation reference line C ′, and the deviation relative to this. The quantity D'is measured. (b) shows the case where the carriage 42 is inclined due to the height difference between the rails 3a and 3b in a curved section or the like, and in this case, the deviation reference line C'is also inclined. On the other hand, the swaying vehicle body 41 inclines to the right as shown in the figure at a certain moment, so that the measurement reference line K inclines to the right of the deviation reference line C'and the deviation amount D'for this is measured.

FIG. 1 is an explanatory view of the principle of the dynamic deviation amount correcting method of the present invention, and FIG. 2 is a configuration diagram of a tilt angle measuring device 7. FIG.
As an example, taking the state of FIG. 7 (b) described above, both the carriage 42 (not shown) and the deviation reference line C ′ are inclined to the left due to the height difference between the two rails 3a and 3b. On the other hand, the swaying vehicle body 41 is tilted to the right with respect to the trolley 42 about the rotation center O, and therefore the measurement reference line K is inclined to the right of the deviation reference line C '. And Inclination angle θ

(1). The vehicle body is now at the position of the deviation measuring device 6.
Assuming a parallel measurement lines M on the floor 411 of the 41, the intersection of the measurement line M and offset reference line C 'p c, the intersection of the measurement reference line K p
d . Draw line segments C ″ and K ′ that are parallel to the deviation reference line C ′ and the measurement reference line K and pass the trolley wire 1, respectively.
The intersections with these measurement lines M are p b and p a , respectively.
Here, both rails 3a, the height of the rotation center O to 3b h 1, the height of the point p c with respect to the rotational center O h 2, the point p c
Let h 3 be the height of the trolley wire 1 with respect to. h 1 is known from the structural dimensions of the electric inspection vehicle 4 ′. However, h 2 and h 3 are unknown, but they do not matter. In the above, the length of p a −p d is the dynamic displacement amount D ′, and the length of p b −p c is the displacement amount D ′.
Respectively. Offset reference line C because 'a measurement reference line K, and the line segment C "a line segment K' respectively forming the inclination angle theta, the length of the p c -p d is (h 2 × tanθ), p a - p
The length of b is (h 3 × tan θ), and the sum of these is the correction amount. Therefore, the length of p b −p c , that is, the displacement amount D with respect to the displacement reference line C ′ is [D ′ − (h 2 + h 3 ) t
an θ]. On the other hand, since the ground clearance H of the trolley wire 1 is measured by the height measuring device, (h 2 + h 3 ) is calculated by (H−h 1 ). From the above, the dynamic deviation amount D '
The correction amount Δx with respect to is calculated by the equation (2): Δx = (H−h 1 ) tan θ .. When it is inserted, the dynamic displacement amount D ′ is corrected and the displacement amount D is obtained.
