It is. The construction of the trolley wire by the trolley wire support device according to the present invention can be performed as follows. The bracket to which the insulator is attached, the set plate, and the supporter are temporarily assembled with the first and second bolts, and then transported to the construction site. First, (1) the base plate of the supporter is mounted on the parapet wall surface with reference to the guide rail. Then, it is fixed by bolts under the adjustment of the vertical height by the vertical slots described above and the adjustment of the falling angle in the train traveling direction by the rotation of the adjustment collar. In this case, the bolts can be easily tightened under the above adjustment while holding the supporter with a lifting jig or the like. (2) Next, the entry / exit direction is adjusted as described above, and further, the adjustment is performed in the up / down direction by the adjustment bolt, and the inclination angle in the entry / exit direction is adjusted by the adjustment collar. During these adjustments, the load can be held by the set plate, the adjustment bolts, the beams, the columns, and the like, and the above adjustment can be performed smoothly. After these adjustments,
The first bolt and the second bolt are tightened, and further, a trolley is attached to each insulator on a gantry, thereby completing the construction. In the above embodiment, the train line support device is mounted on the parapet wall surface of the train track, but it can be mounted on a support post. For example, a frame base is attached to a parapet wall by an anchor bolt or the like, a support is erected on the base, and a train line support device is attached to the support by an anchor bolt or the like on a base plate of a supporter, and the guide rail is supported by the mount. In this case, the train line support device of the present invention can be used. In the above embodiment, the insulator is mounted vertically, but the insulator may be mounted on the bracket in a horizontal direction. In this case, the train is moved in the train traveling direction by adjusting the rotation angle about the pin of the insulator. Since the vertical inclination angle of the line can be adjusted, the supporter may be mounted on the side of the train track by a mounting structure that can only adjust the height position of the train line. According to the train line support device of the present invention,
In a train wire support device in which a base plate of a supporter is attached to a side portion of a train track by bolts and an arm of a train wire holding bracket is fastened to the supporter arm by bolts, a supporter for an anchor member fixed to a train track side portion is provided. The height position of the train line can be adjusted not only by adjusting the height of the supporter but also by adjusting the height of the bracket with respect to the supporter. Even when the adjustment allowance cannot be sufficiently taken, the adjustment allowance is supplemented by the adjustment allowance for the height position of the bracket with respect to the supporter, so that a wide range of height adjustment can be performed as a whole. Therefore, when there is a considerable error in the installation height of the anchor member, for example, even when the anchor member is embedded and installed at the time of constructing the parapet wall, the train line can be easily installed at a predetermined height. Alternatively, the height adjustment margin of the supporter with respect to the anchor member can be reduced by an amount corresponding to the adjustment of the height position of the bracket with respect to the supporter, and the length of the adjustment bolt hole (vertical elongated hole) can be shortened accordingly. Safety can be improved.
