Next, the operation when the hinged jacks 4 and 5 and the hinge 6 are provided between the base 2 and the mounting table 3 will be described.
For example, as shown in FIG. 2 and FIG. 6A, the hinged jack 4 has the pin member 17 whose axial direction is parallel to the longitudinal direction (pitching direction) of the railroad track, and the pin member 20 and the pin member 23. It is arrange | positioned between the base 2 and the mounting base 3 so that an axial direction may become parallel to a transversal direction (rolling direction). In the hinged jack 5, the axial direction of the pin member 17 and the pin member 23 is parallel to the longitudinal direction (pitching direction) of the railroad track, and the axial direction of the pin member 20 is parallel to the short direction (rolling direction). Further, it is disposed between the base 2 and the mounting table 3.
For example, as shown in FIG. 5, in the hinge 6, the axial direction of the pin member 37 is parallel to the longitudinal direction (pitching direction) of the railroad track, and the axial direction of the pin member 40 is the short direction (rolling direction). It is provided between the base 2 and the mounting table 3 so as to be parallel to each other.

Next, with reference to FIG. 9 thru | or FIG. 12, the effect | action of the work table 1 with the horizontal adjustment which concerns on this embodiment mounted on the trolley | bogie 45 which runs on the track | line 46 is demonstrated.
9 (a) and 9 (b) correspond to FIG. 2, FIG. 10 (a) and FIG. 10 (b) correspond to FIG. 3, and show the adjustment of the longitudinal direction (pitching direction) of the railway track 46. FIG. 9 (a) and 10 (a) show a case where the line 46 is inclined and raised forward, and in FIGS. 9 (b) and 10 (b), the line 46 is directed rearward. The case where it is inclined is shown.

  9A and 10A, first, the jack 13 of the hinged jack 5 is driven while looking at the level 43, and the heights of the hinged jack 5 and the hinge 6 are adjusted to be the same. Next, the piston 22 of the hinged jack 4 is lowered while looking at the level 42. As a result, the work table 1 with level adjustment can be swung down with the line connecting the hinged jack 5 and the hinge 6 as the swivel axis, and the base 2 can be level with respect to the horizontal plane 47.

  When the jack 13 of the hinged jack 5 and the jack 13 of the hinged jack 4 are driven to move up and down, a lower hinge 11 and an upper hinge 12 that are pivotable in directions perpendicular to each other are arranged at the lower part of the jack 13, and Since the top hinge 14 is disposed on the upper portion of the jack 13, the lower hinge 11, the upper hinge 12, and the hinge 13 are interlocked with the pivoting action of the hinge 6 so that the vertical movement of the jack 13 is smoothly performed. Each of the top hinges 14 pivots.

  Thus, if the heights of the hinged jack 5 and the hinge 6 are adjusted to be the same, the longitudinal direction (pitching direction) of the railroad track 46 can be adjusted only by lowering the piston 22 of the hinged jack 4. It can be carried out. Thereby, it is possible to perform the adjustment in the pitching direction with certainty instead of adjusting by trial and error.

  Similarly, in FIGS. 9 (b) and 10 (b), the height of the hinged jack 5 and the hinge 6 is adjusted to be the same, and the piston 22 of the hinged jack 5 is raised so that the work with level adjustment is performed. The base 1 can be raised with the line connecting the hinged jack 5 and the hinge 6 as a turning axis, and the base 2 can be made level with respect to the horizontal plane 47.

  11 (a) and 11 (b) correspond to FIG. 4, FIG. 12 (a) and FIG. 12 (b) correspond to FIG. 5, and are diagrams illustrating adjustment in the short direction (rolling direction). . 11 (a) and 12 (a) show the case where the left side of the line 46 is inclined, and the right side of the line 46 is inclined and raised in FIGS. 10 (b) and 12 (b). Indicates the case.

  11A and 12A, first, the jack 13 of the hinged jack 4 is driven while looking at the level 42, and the heights of the hinged jack 4 and the hinge 6 are adjusted to be the same. Next, the piston 22 of the hinged jack 5 is lowered while looking at the level 43. As a result, the work table 1 with horizontal adjustment can be swung down with the line connecting the hinged jack 4 and the hinge 6 as the swivel axis, and the base 2 can be level with respect to the horizontal plane 47.

  Thus, if the heights of the hinged jack 4 and the hinge 6 are adjusted to the same level, the rail 22 can be adjusted in the short direction (rolling direction) simply by lowering the piston 22 of the hinged jack 5. It can be performed. Accordingly, it is possible to perform the adjustment in the rolling direction with certainty instead of adjusting by trial and error.

  Similarly, in FIGS. 11 (b) and 12 (b), the height of the hinged jack 4 and the hinge 6 is adjusted to be the same, and the piston 22 of the hinged jack 4 is lifted to perform the work with level adjustment. The base 1 can be raised with the line connecting the hinged jack 4 and the hinge 6 as a turning axis, and the base 2 can be made horizontal with respect to the horizontal plane 47.

  Here, the hinged jack 4 and the hinged jack 5 are formed longer than the hinge 6 because they include the jack 13 and the like, but the upper portions of the hinged jack 4 and the hinged jack 5 are provided on the base 2. Since the length is occupied between the base 2 and the mounting table 3, there is no great difference between the jack with hinge 4, the jack with hinge 5, and the hinge 6. For this reason, in the adjustment for making the heights of the hinged jack 4 and the hinged jack 5 and the hinge 6 the same, a vertical adjustment in a short range is sufficient.

  If the difference in length between the hinged jack 4, the hinged jack 5, and the hinge 6 can be ignored, the cylindrical bodies 8 and 9 protruding from the upper surface of the base 2 can be omitted.

  As described above, as shown in FIG. 9 and FIG. 10, the work of the base 2 is performed by driving the jack 13 of the hinged jack 4 for pitching adjustment and the jack 13 of the hinged jack 5 for rolling adjustment. It is possible to easily and reliably adjust the pitching direction and the rolling direction so that the surface is parallel to the horizontal plane 47.

Next, a second embodiment of the present invention will be described.
In the first embodiment, an example in which each of the hinged jack 4 and the hinged jack 5 includes at least the lower hinge 11, the upper hinge 12, and the jack 13 has been described. In contrast, in the second embodiment, a pitching adjustment jack is employed instead of the hinged jack 4, and the pitching adjustment jack does not include the lower hinge 11 and the upper hinge 12, but only the jack 13. It has. Further, instead of the hinged jack 5, a rolling adjustment jack is employed, and this rolling adjustment jack is not provided with the lower hinge 11 and the upper hinge 12 but is provided with only the jack 13. The hinge 6 includes a lower hinge 31 and an upper hinge 32.

  In the second embodiment, since the hinge 6 includes the lower hinge 31 and the upper hinge 32, the pitching direction and the rolling direction can be adjusted. Compared to the first embodiment, the pitching direction and the rolling direction can be adjusted. Although it is inferior in the smoothness in adjustment, it becomes possible to measure simplification in the apparatus.

  As described above, in the above description, as the hinged jack 4 and the hinged jack 5, the one shown in FIG. 8 can be adopted instead of the one shown in FIG. 6.

  Further, the mounting table 3 is a frame made of, for example, a rod-like member, if it is not plate-shaped, provided that a hinged jack 4 for pitching adjustment, a hinged jack 5 for adjusting the rolling direction, and the lower surface of the hinge 6 are attached. Also good.

  Further, in the jack 4 with hinge for pitching adjustment and the jack 5 with hinge for rolling adjustment, the order of arrangement in the vertical direction among the lower hinge 11, the upper hinge 12, and the jack 13 is not necessarily shown in FIG. There is no limitation to this, and other arrangement orders may be used.
