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

In the fire hydrant device 1-2 according to the present embodiment, the pedestal 6 is used only as the fixed pedestal 6a, the moving pedestal 6b is not provided, and the housing 4 is provided with a screw hole 4f instead of the screw hole 6ba provided in the moving pedestal 6b. , The housing 4 is directly attached to the fixed pedestal 6a. Further, as the caster 12 instead of the caster 11, one wheel is provided directly on the bottom 4d of the housing 4 on both ends in the width direction. In the case of the present embodiment, a countersunk screw 13 is used instead of the bolt 7 which is a fixing means for fixing the fixed pedestal 6a on the audit path R2. Other configurations are the same as those in the above embodiment.

That is, in the fire hydrant device 1-2, the housing 4 has both ends in the width direction of the front panel 4c and the back plate 4e as alternatives to the screw holes 6ba provided in the mobile pedestal 6b. One screw hole 4f is provided on each side (see FIGS. 5 and 6). Similar to the above, the fixed pedestal 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 each of the side portions 6ac (see the same as above, but not shown). For the sake of convenience, the height dimension of both side portions 6ac is shorter than that in the first embodiment).

The housing 4 is movable with respect to the fixed pedestal 6a in the length direction of the tunnel T, and one screw on both ends in the width direction with respect to any of the plurality of holes 6aa of the fixed pedestal 6a. The holes 4f are housed inside the fixed pedestal 6a so as to face each other, and a common bolt 9 is screwed into the facing holes to be fixed to each other (see FIG. 6).

Thereby, also in the present embodiment, the installation position of the housing 4 installed on the audit path R2 in the length direction of the tunnel T can be changed, and the housing 4 on the audit path R2 can be installed. At the same time, the installation position of the tunnel T in the length direction can be easily adjusted.

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

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

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

Thereby, in the present embodiment, unlike the bolt 7, the head of the countersunk screw 13 can be prevented from protruding onto the fixed pedestal 6a, and the casters 12 are placed on both ends in the width direction on the bottom 4d of the housing 4. Even if one wheel is provided on each side, it is possible to prevent the head of the countersunk screw 13 from interfering with the rolling of the caster 12 (see the same as above).

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

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

Further, as the positioning structure portion of the housing 4 in the length direction of the tunnel T, instead of using holes such as holes 6aa and screw holes 6ba, a fitting structure portion having grooves and protrusions may be used. By doing so, it becomes impossible to use wheels such as casters 11 for traveling and moving the housing 4, but if the housing 4 is lifted and moved, the housing 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 the fitting structure portion with a groove and a protrusion or the like.
