The rigid electrical train-line of support frame

摘要

PROBLEM TO BE SOLVED: To provide a support frame for a rigid electric train wire, capable of achieving easy miniaturization and cost reduction.SOLUTION: A support frame P1 for a rigid electric train wire includes a support frame body 11 of a T-shaped cross section, a trolley wire support part 12 at the lower end of a web 11a of the support frame body 11, and a connection plate fitting shoulder part 13 also serving as an ear protruding to the side in the midway of the web 11a of the support frame body 11. A connection plate 16 is fitted between a slope 21 on the lower surface of a flange 11b and a slope 22a of the shoulder part to be fixed by a bolt 17, so as to be mechanically and electrically connected to the support frame body in its longitudinal direction. A trolley line a is supported and fixed to the support frame body 11 by fixing an ear 14 by a bolt 15. Thus, as the fitting-in slope of the connection plate 16 and the fitting surface of the ear 14 are formed in one shoulder part 13, the support frame can be compact, and materials can be reduced to achieve cost reduction.SELECTED DRAWING: Figure 2
