Link mechanisms A and B connected to rods 8' and 8'' are arranged on the left and right, and recording is performed on a recording paper 10 that is moved on a substrate 9 by the movement of the links.

The link mechanism A is provided with a first oscillating body 11 having a bent portion pivoted on the base plate 9, and one link 11' of the first oscillating body 11 is connected to the rod 8' via a connecting piece 12. The other link 11'' has a recording pen 13 at its tip, and is connected to a sliding piece 15 that slides on the sliding body 14 via a connecting piece 17'. , substrate 9
The other end of the second rocking body 16, one end of which is pivoted P', is connected to the other end of the second rocking body 16 by pins a and b using a connecting piece 17. In addition, the second rocking body 16 has an intermediate portion pivoted to the base plate 9 and one end pivoted to the base plate 9.
A connecting piece 21 is pivotally supported by a shaft 20 together with the bent portion of the fourth oscillator 19 at the tip of the third oscillator 18 having a P'' shape.
Connect to the other end with pin c. Said fourth rocking body 19
, one link 19' is connected to the link 22' of the "shaped fifth rocking body 22, which is pivotally supported P" on the base plate 9, and the connecting piece 23.
are connected through pins d and e, respectively, and the fifth rocking body 2
The tip of the other link 22'' of 2 is connected to the recording pen 24.
is provided and connected via a connecting piece 27 to a recording piece 26 that is slidably fitted onto the sliding body 25.

Next, the link mechanism B on the other side is a sixth link mechanism having a bending part R supported on the base plate 9 in the same way as the link mechanism A.
A rocking body 28 is provided, one link 28' of this sixth rocking body connects the rod 8'' of the cylinder 8 via a connecting piece 29, and the other link 28'' is a sliding body with a recording pen 30 at its tip. Moving piece 15' and connecting piece 31
We are in contact via. The intermediate portion of the link 28'' is connected to one end of the seventh rocking body 32 whose intermediate portion is pivotally supported on the base plate 9 by pins f and g via a connecting piece 33. The end is connected to the other link 19'' of the fourth rocking body 19 via a connecting piece 34 at h and i.

The recording pens 13, 24, 30 are all connected to the substrate 9.
The paper on the reel 35 supported on the upper shaft is wound onto the take-up drum 36 supported on the other end, and while the recording paper 10 stretched between the reel 35 and the take-up drum 36 is fed out, the link mechanism operates. I draw.

As is clear from the above-mentioned configuration, the present invention, for example, has high and low levels on the left and right sides of the rail, and if the rail twists and goes out of order, and the left side of the front wheel is lower, the vehicle body will twist. Therefore, this torsional displacement is as follows: The cylinder rod 8' swings the first rocking body 11 in the → direction about the axis P via the connecting piece 12, and the movement of the rocking body 11 is The tip of one link 11'' swings to move the sliding piece 15 provided on the recording pen 13 in the → direction via the connecting piece 17', thereby recording the height displacement on the recording paper 10 being transported. Further, the second swinging body 16 connected to the link 11'' via the connecting piece 17 swings in the → direction about the axis P'. Furthermore,
With this swinging motion, the second swinging body 16 moves the third swinging piece 18, which is supported by the shaft P'', through the connecting piece 21 →
While swinging in the direction, the fourth swinging body 19
It swings in the → direction around the center. At this time, the fourth oscillator 1
9 connects the fifth rocking body 22 to the axis P via the connecting piece 23.
The fifth oscillating body 22 further moves the recording pen 24 provided on the recording paper 26 in the → direction via the connecting piece 27 to record the difference in displacement between left and right heights on the recording paper 10. will be done. Further, the link mechanism B does not operate with twisting when one side is low and the other side is flat.

Next, if the rail on the opposite side is twisted due to high or low height, the action is shown by the chain line, and the cylinder 8 connects the rod 8'' via the connecting piece 29 to the sixth oscillating body 28 with R as the center. The sliding piece 15' connected to the tip swings in the −-→ direction.
moves in the --→ direction and records the displacement with the recording pen 30. In addition, the sixth rocking body 28 swings to support the shaft.
When the seventh rocking body 32 swings in the -→ direction centering on R', the connecting piece 34 connected to one end swings the fourth rocking body 19 in the -→ direction centering on the shaft 20, and the connecting piece The fifth rocking body 22 is swung in the --→ direction via the connecting piece 23, and the recording piece 26 connected thereto via the connecting piece 27 is moved in the --→ direction, and the recording pen 24 is used to measure the difference in displacement between left and right heights. The measurement is recorded on the recording paper 10.

If the left and right rails move vertically by the same amount, the sliding pieces 15, 15' move and the sliding pieces 15, 15' move.
Left and right displacement recording pens 13 and 30 provided at 15' record the vertical amount. However, in this case, the connecting pieces 34 connecting the links 19' of the seventh swinging body 32 and the fourth swinging body 19 move in the same direction, so the fifth swinging body 22 does not swing. Therefore, no recording is performed on the recording piece 26. Regarding the front wheels 4, 4, even if the left and right wheels of the front wheels move up and down by the same amount at the same time, the sliding pieces 15 and 15' move and record, but the recording piece 26 does not move, so there is no deviation in the plane of the trajectory. This is to record the two-dimensional deviation recorded by the movement of the recording piece 26.

As mentioned above, the inspection vehicle 1 is composed of two vehicle bodies 1' and 1'' connected around the inspection wheel 2 provided in the center, and the wheels 4 and 5 are arranged at the front and rear of this inspection vehicle 1. Furthermore, each body 1', 1'' of the inspection vehicle 1 is provided with a frame 7', 7'', and the opposite side of the frame 7', 7'' is provided with an inspection wheel. cylinders are installed on both sides of one of the opposing frames 7', and a substrate 9 of the recording device is installed on the other frame 7''.
Link mechanisms A and B connected to the rods 8' and 8'' from the left and right cylinders are arranged on the left and right sides on this board 9, and the link mechanisms A and B are operated by the bending and stretching movements of the inspection vehicle 1. The measurement is recorded using a recording pen on the recording paper transferred between the two link mechanisms, and the twist of the rail during running is reliably recorded on the recording paper 10 by the link mechanisms A and B. This has the effect of making it possible to fully understand the measurement results from the hetogram.
