Document Type and Number:
Japanese Patent JP7263081
Kind Code:
B2
Abstract:
To provide an insulator support structure that prevents troubles such as damage of a swing bracket, even when an over-head earth wire is largely swung, by simultaneously allowing a swing bracket contained in a tan type metal fitting that becomes a suspension member to swing in a sleeper direction, and swing in a rail direction.SOLUTION: An insulator support structure 200 containing a tan type metal fitting 40 for making a bracket 1 of a pillar support the insulator 50 between itself and an over-head earth wire GW, in which the tan type metal fitting 40 has a securing bracket 11 connected to a bracket 1 of the pillar, and a swing metal fitting 12 provided so as to swing freely via a first rotation axis 41 (axis line a4) that allows a securing bracket 11 to swing in a sweeper direction A and connected to an upper part of the insulator 50. In the lower part of the insulator 50, an overhead line mounting bracket 3 supporting the overhead earth wire GW is provided via a second rotation axis 30 (axis line b3) allowing it to swing in a rail direction orthogonal to the sleeper direction A.SELECTED DRAWING: Figure 1
