The displacement sensor 21 of 1 and the second displacement sensor 22 are provided in pairs.
The first displacement sensor 21 and the second displacement sensor 22 are, for example, laser displacement sensors that measure the dimension between the displacement sensor and the object to be measured (distance from the displacement sensor to the object to be measured). is there.

In the present embodiment, in the process of the rail adjusting packing thickness measuring device 100 moving along the rail R, a predetermined point (here, the rail R is a displacement T (see FIG. 1) or a PC pillow M (see FIG. 3)). The first displacement sensor 21 and the second displacement sensor 22 measure the dimensions for measuring the thickness of the rail adjusting packing P, respectively, when they are above the point fixed to the rail.
Specifically, in a state where the device main body 10 (rail adjusting packing thickness measuring device 100) is above a predetermined point (a state where the device body 10 (rail adjusting packing thickness measuring device 100) is stopped above a predetermined point), the first displacement sensor 21 has a track structure. The second displacement sensor 22 is arranged at a position to measure the dimension up to the "reference plane" set on the upper surface of the object (typate T, PC maculagi M), and the second displacement sensor 22 is an orbital structure (typrate T, PC maculagi M). ) It is configured to be placed at a position to measure the dimension up to the "reference position" set on the upper surface of the bottom of the rail R fixed via the rail adjustment packing P, and is the first displacement sensor. 21 measures the dimension to the reference plane, and the second displacement sensor 22 measures the dimension to the reference position.
In the rail adjustment packing thickness measuring device 100, two sets of the first displacement sensor 21 and the second displacement sensor 22 each measure the thickness of the rail adjustment packing P on the left and right rails R.

A laser used for aiming when the first displacement sensor 21 measures the dimension up to the "reference plane" and the second displacement sensor 22 measures the dimension up to the "reference position". A sighting device such as a pointer may be provided in the apparatus main body 10.
Then, after aiming the first displacement sensor 21 and the second displacement sensor 22, the terminal device 30 is operated by the displacement sensor (first displacement sensor 21, second displacement sensor 22). Perform dimensional measurements.
The dimensional data measured by the first displacement sensor 21 and the second displacement sensor 22 are sent to the terminal device 30 via a cable or wireless communication (not shown).

The terminal device 30 is a so-called tablet terminal including, for example, a control unit (CPU), a storage unit, a display unit, an operation unit, an audio output unit, a communication unit, and the like, and functions as a display unit and an operation unit. It has a touch panel.
The terminal device 30 that functions as the packing thickness calculating means has the dimensions from the dimension to the "reference plane" measured by the first displacement sensor 21 to the "reference position" measured by the second displacement sensor 22. While subtracting the fixed value related to the thickness of the bottom of the rail R at the reference position, add or subtract the fixed value related to the height difference between the position corresponding to the vertical direction of the reference position on the surface on which the rail adjustment packing P is placed and the reference surface. The thickness of the rail adjusting packing P is calculated by executing the processing (addition or subtraction processing).

Specifically, when the track structure is a tie plate T, for example, as shown in FIG. 2, the terminal device 30 functioning as the packing thickness calculation means has the dimensions up to the reference plane measured by the first displacement sensor 21. The dimension "A" from "B" to the reference position measured by the second displacement sensor 22 and the fixed value "α" regarding the thickness of the bottom of the rail R at the reference position are subtracted, and the rail adjustment packing P is mounted. The thickness of the rail adjustment packing P is increased by executing the process of adding a fixed value "β" regarding the height difference between the reference surface and the position lower than the reference surface corresponding to the vertical direction of the reference position on the placed surface. "t" is calculated.
As shown in FIG. 2, when the track structure is a tie plate T, the surface on which the rail adjusting packing P is placed on the tie plate T is at a position lower than the reference surface, so that the height difference from the reference surface is high. The thickness "t" of the rail adjustment packing P is calculated by executing the process of adding the fixed value "β".
That is, when the track structure has a tie plate T, the formula for calculating the thickness “t” of the rail adjusting packing P is the following formula (1). This equation (1) is stored in the storage unit of the terminal device 30.
t = (BA) -α + β ... (1)

When the track structure is the PC mackerel M, for example, as shown in FIG. 4, the terminal device 30 functioning as the packing thickness calculation means has the dimension “B” up to the reference plane measured by the first displacement sensor 21. From, the dimension "A" to the reference position measured by the second displacement sensor 22 and the fixed value "α" regarding the thickness of the bottom of the rail R at the reference position are subtracted, and the rail adjustment packing P is placed. The thickness "t" of the rail adjustment packing P is calculated by subtracting the fixed value "γ" related to the height difference between the reference surface and the position higher than the reference surface corresponding to the vertical direction of the reference position on the surface. calculate.
As shown in FIG. 4, when the track structure is the PC sleeper M, the surface on which the rail adjustment packing P is placed on the PC sleeper M is higher than the reference surface, so that the height difference from the reference surface is higher. The thickness "t" of the rail adjustment packing P is calculated by executing the process of subtracting the fixed value "γ".
That is, when the track structure is the PC sleeper M, the formula for calculating the thickness “t” of the rail adjusting packing P is the following formula (2). This equation (2) is stored in the storage unit of the terminal device 30.
t = (BA) -α-γ ... (2)

Then, the thickness "t" of the rail adjusting packing P calculated by the terminal device 30 as the packing thickness calculating means is stored in the storage unit of the terminal device 30 and displayed on the display unit of the terminal device 30.
In addition, when starting the thickness measurement of the rail adjustment packing P by the rail adjustment packing thickness measuring device 100, whether the end device 30 is operated to measure the track whose track structure is the tie plate T or the track structure Is now to select whether to measure the orbit of the PC sleeper M.
By performing the selection operation, the processing by the terminal device 30 functioning as the packing thickness calculation means can be switched between the one according to the equation (1) and the one according to the equation (2).

Further, in the present embodiment, the "reference position" set on the upper surface of the bottom of the rail R fixed on the track structure (typrate T, PC sleeper M) via the rail adjustment packing P is the rail R. It was assumed that the position was 6.5 [mm] inside the end face of the bottom (see FIGS. 2 and 4).
The "reference position" is not limited to the position 6.5 [mm] inside the end face of the bottom of the rail R, and any position can be set. However, it goes without saying that each fixed value (α, β, γ) changes depending on the set position of the “reference position”.
Further, the fixed value "α" changes according to the type of rail R, the fixed value "β" changes according to the type of type rate T, and the fixed value "γ" changes according to the type of PC sleeper M. Of course.
Each fixed value (α, β, γ) is input to the terminal device 30 in advance and stored in the storage unit of the terminal device 30.

Further, in the terminal device 30, the rail adjusting packing thickness measuring device 100 moves a distance corresponding to a preset interval of predetermined points based on the moving distance of the rail adjusting packing thickness measuring device 100 measured by the encoder 40. Each time, it functions as a notification means for prompting the measurement of the thickness of the rail adjustment packing P.
For example, with respect to an orbit in which the orbital structure is a tie plate T, the distance between the sleepers W to which the tie plate T is fixed is stored in advance in the storage unit of the terminal device 30.
Similarly, with respect to the orbit in which the orbital structure is the PC sleeper M, the interval of the PC sleepers M is stored in advance in the storage unit of the terminal device 30.

Then, when starting the thickness measurement of the rail adjustment packing P by the rail adjustment packing thickness measuring device 100, the terminal device 30 is operated to measure the track whose track structure is the tie plate T, or the track structure. By selecting whether to measure the trajectory of the PC Macragi M, the rail adjustment packing thickness measuring device moves from the predetermined point where the thickness measurement of the rail adjustment packing P is completed to the next predetermined point. When 100 is moved, when the rail adjusting packing thickness measuring device 100 reaches the next predetermined point which is the measuring point, a message indicating that it is the measuring point is displayed on the display unit of the terminal device 30 or the terminal device is used. From 30 onward, a chime indicating that it is a measurement point is sounded to notify the thickness of the rail adjustment packing P to be measured.
In this way, when the rail adjustment packing thickness measuring device 100 moves from the predetermined point where the dimension measurement is completed to the next predetermined point, the terminal device 30 as the notification means notifies that the measurement point is the rail. The operator who operates the adjusting packing thickness measuring device 100 can be warned not to pass a predetermined measurement point.

As described above, the rail adjusting packing thickness measuring device 100 of the present embodiment has a track regardless of whether the track structure is a track having a tie plate T or a track structure is a PC Macragi M. In the process of moving along the rail R of the rail R, the dimensional measurement is performed from above the predetermined point where the rail R is fixed to the track structure (type rate T, PC maculagi M), and the rail R and the track structure ( It is possible to measure the thickness "t" of the rail adjusting packing P interposed between the tie plate T and the PC makuragi M.

In this way, if the thickness of the rail adjusting packing P interposed between the rail R and the track structure (tie plate T, PC sleeper M) can be measured, the thickness does not satisfy the specified value. Since the deteriorated rail adjustment packing P can be quickly found, track maintenance for taking measures such as replacing the rail adjustment packing P can be preferably performed.

In the above embodiment, the thickness of the rail adjustment packing P is calculated in the terminal device 30, but the present invention is not limited to this. For example, the terminal device 30 can be used as an SD card or a device. The measurement data of the displacement sensors (first displacement sensor 21, second displacement sensor 22) is taken out to a computer for analysis via a USB memory or the like, and the rail adjustment packing P is used in a computer that functions as a packing thickness calculation means. The thickness may be calculated.

In addition, it goes without saying that the specific detailed structure and the like can be changed as appropriate.
