By changing the combination of holes facing each other 6ba and changing the combination of holes fixed by a common bolt 9, the position can be changed in the length direction of the tunnel T.

  Here, in the present embodiment, in the gantry 6, the length of the fixed gantry 6 a in the longitudinal direction is longer than the length in the width direction of the housing 4. It may be shorter than the length in the width direction (not shown). Further, the hole 6aa on the fixed frame 6a side and the screw hole 6ba on the movable frame 6b may be reversed, and both of them are holes without threading and are replaced with bolts 9 which are fixing means for both. It is good also as a pin which gave dropout prevention (illustration omitted). Further, the plurality of holes 6aa on the fixed base 6a side may be elongated holes along the length fitting direction of the tunnel T (not shown) instead of using the plurality of holes.

  Furthermore, without providing the moving gantry 6b, a screw hole may be provided in the housing 4 in place of the screw hole 6ba provided in the moving gantry 6b, and the housing 4 may be directly attached to the fixed gantry 6a. A specific example thereof will be described in detail as a second embodiment in the postscript.

[Installation support (an example of a support member)]
Furthermore, in the case of the present embodiment, the fire hydrant device 1-1 is an installation support 10 provided to form a leg at the lower part of the bottom 4d of the housing 4 as an example of a support member for supporting the housing 4 from below. (See FIGS. 1 to 4).

  Since the fire hydrant device 1-1 includes the installation support 10, the casing 4 can be aligned in the height direction with respect to the gantry 6, and the installation position of the casing 4 in the length direction of the tunnel T is provided. Can be adjusted more easily. Specifically, for example, in the case of this embodiment having a hole 6aa provided in the fixed gantry 6a and a screw hole 6ba provided in the movable gantry 6b as positioning holes for the housing 4 in the length direction of the tunnel T, With the installation support 10, the height position of the hole 6 aa on the fixed frame 6 a side and the screw hole 6 ba on the movable frame 6 b side can be matched by simply mounting the movable frame 6 b together with the housing 4 on the fixed frame 6 a. This eliminates the need for the work of aligning the position in the height direction. Thus, the installation position of the housing 4 in the longitudinal direction of the tunnel T can be adjusted more easily.

  In the present embodiment, a pair of installation supports 10 are provided at the center of the bottom 4d of the casing 4 with a gap in the width direction, and both have a box-like shape. The number and the shape may be changed as appropriate as long as they can support the lower side from the lower side and determine the height position, and may be provided on the side of the fixed mount 6a.

[Caster (an example of a wheel)]
Furthermore, in the case of the present embodiment, the fire hydrant device 1-1 includes casters 11 provided on each of the bottoms 6bd of the pair of movable stands 6b as an example of a wheel for moving the housing 4 (FIG. 1 to FIG. 4).

  Since the fire hydrant device 1-1 includes the caster 11, the casing 4 can be easily moved, and the installation position of the casing 4 in the length direction of the tunnel T can be adjusted more easily. it can.

  In the present embodiment, each of the casters 11 is provided so as to be separated by two in the depth direction of the housing 4 (see FIGS. 2 and 3). Thereby, even if the head of the bolt 7 that fixes the bottom 6ab of the fixed base 6a on the inspection path R2 protrudes, it can be prevented that it interferes with the rolling of the caster 11. Moreover, the caster 11 can be made height adjustable. By doing so, heightwise alignment of the housing 4 with respect to the mount 6 can be enabled without the installation support 10 described above. That is, in the case of this embodiment, by making the height of the caster 11 adjustable, the height direction positions of the hole 6aa on the fixed gantry 6a side and the screw hole 6ba on the movable gantry 6b side are casted on the fixed gantry 6a. 11 can be matched only by mounting the movable stand 6 b provided with the housing 11 together with the housing 4. In addition, the caster 11 may be provided also in the installation support 10, and even when there is no installation support 10, you may provide.

  Here, the casters 11 may be provided directly on the housing 4 or may be provided one by one in the depth direction of the housing 4. Specific examples thereof will be described in detail as a second embodiment in the later description, together with the case where the housing 4 is directly attached to the fixed rack 6a.

Second Embodiment
A fire hydrant device 1-2 according to a second embodiment of the present invention will be described with reference to FIGS. 5 and 6.

  The fire hydrant device 1-2 according to the present embodiment is provided with a screw hole 4f instead of the screw hole 6ba provided in the movable stand 6b in the housing 4 with the mount 6 only as the fixed stand 6a and without the movable stand 6b. The housing 4 is directly attached to the fixed base 6a. Further, as the caster 12 replacing the caster 11, one wheel is provided directly on the bottom 4d of the housing 4 at each of both widthwise end sides. In the case of the present embodiment, a countersunk screw 13 is used in place of the bolt 7 which is a fixing means for fixing the fixed base 6a on the inspection path R2. Other configurations are the same as those in the above-described embodiment.

  That is, in the fire hydrant device 1-2, the casing 4 is replaced with both ends of the casing 4 in the width direction on the front panel 4c and the rear plate 4e, in place of the screw holes 6ba provided in the movable mount 6b. One screw hole 4f is provided on each side (see FIGS. 5 and 6). As described above, the fixed frame 6a is provided with a plurality of holes 6aa arranged at intervals along the longitudinal direction, that is, the length direction of the tunnel T, on both side portions 6ac (see the same as above, but shown in the figure). For the sake of convenience, the dimensions in the height direction of both side portions 6ac are shorter than those in the first embodiment.

  The housing 4 is movable in the length direction of the tunnel T with respect to the fixed mount 6a, and one screw at each of both end sides in the width direction with respect to any of the plurality of holes 6aa of the fixed mount 6a. The holes 4f are housed inside the fixed mount 6a in the facing direction, and are attached by screwing a common bolt 9 into the facing holes and fixing them together (see FIG. 6).

  Thereby, also in this embodiment, the installation position in the length direction of the tunnel T of the casing 4 installed on the inspection path R2 can be changed, and the casing 4 on the inspection path R2 can be installed. While being able to do, the installation position in the longitudinal direction of the tunnel T can be adjusted easily.

  Further, in the present embodiment, as an alternative to the caster 11, the caster 12 is provided on the bottom 4d of the housing 4 directly on the both ends in the width direction, one wheel at a time (FIGS. 5 and 6). reference).

  Thereby, also in the present embodiment, the housing 4 can be easily moved, and the installation position of the housing 4 in the longitudinal direction of the tunnel T can be adjusted more easily.

  Furthermore, in the present embodiment, a countersunk screw 13 is used in place of the bolt 7 which is a fixing means for fixing the bottom portion 6ab of the fixed base 6a on the audit path R2 (see FIG. 6).

  Thus, in the present embodiment, unlike the bolt 7 described above, the head of the countersunk screw 13 can be prevented from projecting onto the fixed mount 6a, and the caster 12 is placed on the bottom 4d of the housing 4 at both ends in the width direction. Even if one wheel is provided on each side, the head of the countersunk screw 13 can be prevented from interfering with the rolling of the caster 12 (see the same as above).

  As mentioned above, although embodiment of this invention was described, this invention is not limited to said embodiment.

  For example, the scale may be attached to the gantry 6 (for example, the fixed gantry 6a side). By doing so, the movement width can be confirmed by the scale, and the movement operation can be easily made accurate.

  In addition, the positioning structure portion of the housing 4 in the length direction of the tunnel T may be a fitting structure portion including grooves and protrusions instead of holes such as the holes 6aa and the screw holes 6ba. By doing so, it becomes impossible to use wheels such as casters 11 that travel and move the casing 4, but if the casing 4 is lifted and moved, the casing 4 in the length direction of the tunnel T can be used. The position can be changed, and positioning can be performed at a desired position by fitting a fitting structure such as a groove and a protrusion.
