DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable bracket for supporting a train line.

[0002]

2. Description of the Related Art Conventionally, as a movable bracket for supporting a train line, a movable bracket which suppresses an eccentric load generated in the train line when the track is curved, and a movable bracket which supports a straight line when the track is straight,
In order to prevent the flow of the train line due to the wind and to prevent the local wear of the train pantograph, the model is roughly classified into a model that suppresses an uneven load of the train line when the train line is laid in a zigzag shape. FIG. 9 shows a configuration in the case where the unbalanced load of the train line is suppressed from the outside of the utility pole and FIG. 9 from the utility pole side. That is, in the figure, reference numerals 30 and 31 denote insulators fixed to the upper and lower positions of the electric pole 32 via the band 33,
The upper insulator 30 has a horizontal main pipe 3 extending horizontally in the line direction and having a plurality of adjusting holes 34 in the front longitudinal direction.
5 is attached to the lower insulator 31. A slanted main pipe 36 is attached to the lower insulator 31 and is inclined upward and has a front end connected to an intermediate position of the horizontal main pipe 35. The rear end of a horizontal fitting 37 extending horizontally in parallel with the horizontal main pipe 35 is attached.
7 is the horizontal main pipe 3 by auxiliary fittings 38 and 39.
5 is supported at the front and rear positions. At the distal end of the horizontal pipe 33, a holding bracket 40 for a suspension line a attached so as to be movable and adjustable in the longitudinal direction at the position of the adjusting hole 34, and after a curved pulling fixture c supporting a trolley wire b at the distal end. The end is attached via a retaining bracket 41.

[0003]

However, according to the above-described structure, as is apparent from FIGS. 8 and 9, the members to be used, that is, at least the horizontal bracket 37 and the auxiliary bracket 38 are different depending on the type of the device that suppresses the eccentric load. Since the lengths are different, selection of the model, construction preparation and production are complicated, and in the configuration of FIG. 8 in which the unbalanced load is suppressed from outside the telephone pole, the horizontal bracket 37 protrudes greatly in front of the trolley wire b. Therefore, when replacing the suspension line a, it is difficult to cross the tip of the horizontal bracket 37, there is a risk of approaching the adjacent line, and when adjusting the train line after the equipment,
There were inconveniences, such as having to perform the suspension wire and the trolley wire separately.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned disadvantages of the prior art, the present invention extends forwardly through insulators at the upper and lower positions of a utility pole so that the components can be used in common. While holding the horizontal main pipe and the rear end of the oblique main pipe inclined upward, respectively, and extending the front part of the oblique main pipe horizontally, a horizontal part is formed by the front part and the horizontal main pipe, A support bracket having a suspension wire holding part on the upper part and a mounting part on the lower part is mounted on the horizontal part so as to be position-adjustable in the horizontal direction, and a pull-down fitting supporting the trolley wire is fixed to the mounting part. Specifically, adjustment holes are provided at the front of the horizontal main pipe and the front of the oblique main pipe along the length direction thereof, respectively, and the front end of the horizontal main pipe is provided. And the front front end of the inclined main pipe And, the middle part of the horizontal main pipe and the front rear end of the oblique main pipe are connected by a pivoting piece to form a horizontal part, and the support bracket is formed by connecting one metal plate downward U-shaped. The lower part of the double-sided plate is closed in a curved shape, and the front part of the horizontal main pipe forming the horizontal part and the front part of the oblique main pipe are slidably fitted in the vertical position. Portion, a mounting portion having a bulging hollow portion in the middle portion, and hanging in a front-rear direction provided on a top surface of the main portion, while hanging downwardly from a lower edge of a double-sided plate of the main portion. A holding portion having a locking rod for locking a suspension wire between a pair of opposed standing pieces, and a main portion is bolted to a horizontal portion at a position of the adjustment hole.
It is fastened by a nut, and a pull fitting extends in the longitudinal direction at the front of a hollow tubular material bent in a rectangular shape in the longitudinal direction, and projects in the diametrical direction, and the mounting hole extends in the longitudinal direction. A pair of upper and lower auxiliary ribs are provided, and at the rear end, a retaining portion for retaining a curved metal fitting is provided. The front end of the metal fitting is sandwiched between both side plates of the mounting portion, and the position of the mounting hole is provided. Attach the auxiliary rib to the mounting
It is fixed by a nut.

[0005] Thus, by moving the mounting bracket in the horizontal direction corresponding to the distance between the utility pole and the electric wire, the suspension wire and the trolley wire can be adjusted simultaneously. If the direction in which the eccentric load of the trolley wire is suppressed is different, only the direction of the retaining fitting may be changed in accordance with the direction.
