で、前記先発明を適用したものである。 An example will be described with reference to the figures. One end of the horizontal member 1 is supported by a column 2 via an insulator G, and is rotatable in a horizontal plane. One end of the support member 3 is rotatably supported by the column 2 below the horizontal member via the insulator G, and the other end is locked to the center of the horizontal member. The fixing member 4 is made by integrating a mounting member 4a, a cylindrical shaft 4b, and a suspension wire receiving portion 4c. The mounting member 4a has a U-shaped cross section, holds the free end side of the horizontal member 1, and is fixed to the horizontal member with a through bolt 5. A plurality of bolt holes 1a are drilled in the horizontal member so that its fixing position can be adjusted in the axial direction of the horizontal member. A receiving part 4c capable of supporting the hanging wire M is fixed to the outer upper part of the fixing member 4, and a cylindrical shaft 4b is fixed to the inner lower part thereof in a vertically downward direction. A link device L consisting of a vertical plate 6, two arms 7, 8, and a rod 9 is attached to the cylindrical shaft 4b. The vertical plate 6 is rotatably supported by the cylindrical shaft 4b at one side thereof.
The upper ends of the arms 7 and 8 are pivotally mounted near the lower side of the vertical plate 6 at appropriate intervals. One end of the rod 9 is pivotally connected to the lower ends of the two arms 7 and 8 at an appropriate interval, and the other end is inclined downward, and a contact line T is attached to the lower end.
It is equipped with ears E that can hold the. The ear E is located directly below the hanging wire receiver 4c. The above-described link device L allows the ear E to move vertically within a certain range by appropriately selecting its four pivot points, and is an application of the earlier invention.

支障なく可動ブラケツトの作用を果す。 The present invention is configured as described above. The suspension wire M is a steel stranded wire, and the overhead contact wire T is a copper bar material. Although a difference in elongation occurs between the two due to temperature changes, the link device L rotates around the cylindrical shaft 4b to easily compensate for this difference. If both flow in the same direction, the horizontal member and support member will rotate around the center of the column. Also, as mentioned above, the ear E does not move left or right even when raised or lowered, so
The movable bracket functions without any problems.

必要とする。 In order to clarify the features of the present invention, a known movable bracket will be explained and then compared with it. The known ones differ in shape depending on the "outward pull" which is pulled from the opposite side of the column and the "inner pull" which is the opposite, but the outward pull is shown in FIG. 2 and the inward pull is illustrated in FIG. 3. First, in FIG. 2, in addition to the horizontal member 1 and the support member 3, a lower horizontal member S, a reinforcing diagonal member H, and a curved trigger R are provided. In this configuration, it is not preferable to increase the pull angle θ of the curved pull fitting R.
This is because as the pull angle increases, the overhead contact wire also increases, impairing current collection performance. Reduce the handle angle,
Moreover, in order to avoid contact with the pantograph,
The curved trigger R must be sufficiently long. In order to support the curved trigger fitting, it is necessary to attach a lower horizontal member S, but this also has to be long. The lateral tension applied to the overhead contact line is supported at the center of the support member via the curved pull fitting R and the lower horizontal member S, causing the support member to bend. In addition, the lower horizontal members may float due to wind pressure. In order to prevent both of these, a reinforcing member H is required. Next, for the inward pull shown in FIG. 3, in addition to the above-mentioned members, a specially shaped mounting bracket K is required for mounting the curved trigger tool R.
これに対し本発明では外側引き内側引きを区別

できる。以上が本発明の特徴である。 On the other hand, in the present invention, there is no need to distinguish between outward pull and inward pull, and it is possible to unify them into one type. The lower horizontal member S and reinforcing diagonal member H become unnecessary. In the case of the link device, since the overhead contact line can be raised and lowered only within a certain limited range, the conditions for the pull angle θ are relaxed, and the rod 4 may be significantly shorter than the curved pull fitting R. The whole becomes noticeably more compact. Since the height of the entire movable bracket is shortened based on the height position of the overhead contact line, the pillar can also be made smaller and lighter. The above are the features of the present invention.
