Document Type and Number:
Japanese Patent JP2019014322
Kind Code:
A
Abstract:
To prevent rotation of a catenary cable protection cover.SOLUTION: A catenary cable protection cover 10 comprises: an elliptic cross-sectional body part 11 for hooking a hanger ear H; and an insertion hole 12 for a catenary cable, provided inside the body part 11 and eccentrically in the direction of the long axis of the ellipse. The catenary cable protection cover 10 can be divided into a first member 60 and a second member 70 with the insertion hole 12 between them, and rotation blocking parts 13, 14 that block rotation around the catenary cable are provided around the body part 11. By virtue of such a configuration, a height adjustment is made by 180° inversion of the catenary cable protection cover 10, and rotation is blocked by the rotation blocking parts 13, 14, thereby making it possible to hold the height of a trolley wire after the adjustment.SELECTED DRAWING: Figure 1
