Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeder support device for supporting a feeder for a train line that is extended along a wall surface of a railroad road while ensuring a predetermined insulation interval with respect to the wall surface of the railroad road.
[0002]
[Prior art]
Conventional electric wires are supported by two insulators on the wall surface of the tunnel, but there is a difficulty that it is not easy to adjust the insulation interval with respect to the wall surface.
[0003]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a wire support device that can easily adjust the insulation interval with respect to the wall surface.
[0004]
[Means for Solving the Problems]
In the present invention, in order to solve the above-mentioned problems, the upper mounting bracket 2 and the lower mounting bracket are attached to the wall surface T above and below the feeder line W for the train line extending along the wall surface T of the tunnel. 3 is fixed, the upper end of the upper insulator 4 is pivoted on the upper mounting bracket 2, the lower end of the lower lever 5 is pivoted on the lower mounting bracket 3, and the lower end of the upper insulator 4 and the upper end of the lower lever 5 are pivoted. 6 and is provided at one end of the pivot pin 6 with a wire-carrying member 7. At least one is provided between the upper insulator 4 and the upper mounting bracket 2 or between the lower insulator 5 and the lower mounting bracket 3. The feeder support device 1 in the saddle road was constructed by interposing an adjustment fitting 8 for adjusting the pivotal support position of the insulators 4 and 5 up and down.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a feeder wire support device, FIG. 2 is a front view of a feeder wire retaining member, FIG. 3 is a plan view of the feeder wire retaining member, and FIG.
[0006]
In FIG. 1, the feeder support device 1 supports a feeder for a train line, which is extended along the wall surface T of the tunnel, with a predetermined insulation interval between the feeder and the wall surface T.
[0007]
The feeder support device 1 includes an upper mounting bracket 2 and a lower mounting bracket 3, an upper insulator 4 and a lower insulator 5, and an electric wire retaining member 7 attached to a pivot pin 6.
[0008]
The upper mounting bracket 2 and the lower mounting bracket 3 are fixed to the wall surface T above and below the feeder wire W.
[0009]
The upper insulator 4 is a polymer insulator having a clevis portion 4 a at the upper end and an eye portion 4 b at the lower end, and the clevis portion 4 a is pivotally supported by the upper mounting bracket 2. The lower insulator 5 is a polymer insulator having a clevis portion 5 a at the upper end and an eye portion 5 b at the lower end, and the eye portion 5 b is pivotally supported by the lower mounting bracket 3 via the adjustment fitting 8.
[0010]
The eye part 4 b at the lower end of the upper insulator 4 and the clevis part 5 a at the upper end of the lower insulator 5 are pivoted to each other by a pivot pin 6. An electric wire retaining member 7 is provided on one end side of the pivot pin 6. The feeder terminal member 7 includes a base 7a fixed to one end of the pivot pin 6, and a J-type bolt 7b fixed to the base 7a with a nut 7c. The J-type bolt 7b, the base 7a, In the meantime, the feeder W is held.
[0011]
An adjustment fitting 8 is interposed between the lower insulator 5 and the lower mounting bracket 3 so that the pivot position of the lower insulator 5 can be adjusted up and down. The adjustment fitting 8 includes an eye fitting 8a and a clevis fitting 8b. The eye metal fitting 8a has an eye portion 8c pivotally supported by the lower mounting metal fitting 3 and a bolt insertion portion 8d connected to the clevis metal fitting 8b. The clevis fitting 8b includes a clevis portion 8e and a screw rod portion 8f. The clevis portion 8e is pivotally supported by the eye portion 5b of the lower lever 5. The screw rod portion 8f is inserted into the bolt insertion portion 8d of the eye metal fitting 8a and fixed with a nut 8g. The upper and lower insulators 4 and 5 may be changed in the vertical direction so that the adjustment fitting 8 is interposed between the upper insulator 4 and the upper mounting bracket 2.
[0012]
【The invention's effect】
As described above, the thus configured supporting device 1 of the present invention can easily support the feeder wire W by pivotally supporting the ready-made polymer insulators 4 and 5 with the pivot pin 6 with the wire retaining member 7. By adjusting the adjustment fitting 8, there is an effect that the vertical position of the feeder wire W and the separation position from the wall surface T can be easily adjusted.
