Description

[Detailed Description of the Invention] The present invention relates to a hanger for suspending an overhead contact line below an overhead wire. Conventional hanger ears using a round bar for the hanger bar had the lower end of the hanger bar crimped to one of the ear pieces. For this reason, although the round bar material can be obtained at a relatively low cost, there is a disadvantage that crimping the ear pieces is expensive.

The present invention was developed by focusing on the above-mentioned points of the conventional hanger bar, and has a structure in which an eye is formed at the lower end of the hanger bar, and a pair of ear pieces are attached with bolts across this eye. By doing so, we aim to provide an inexpensive but robust hanger.

Embodiments of the present invention will be described below with reference to the figures. The hanger bar 1 is made of a round bar, and a suspension wire M is attached to the upper end.
It has a latching part 2 for latching onto the body, and has a bent eye part 3 at the lower end.

A pair of ear pieces 4 and 5 are attached to the lower end of the hanger bar 1 with the eye part 3 interposed therebetween. The ear pieces 4 and 5 have bolt through holes 6 and 7 corresponding to the eye portion 3 at centrally opposing positions, respectively, and a bolt 8 and a nut 9 passing through these bolt through holes 6 and 7 and the eye portion 3. are attached to the lower ends of the hanger bars 1, and grip the overhead contact line T at their lower parts. Annular projections 10 and 11 are formed on the peripheries of the inner bolt through holes 6 and 7 of both ear pieces 4 and 5, and these projections 10 and 11 fit into the eye portion 3 of the hanger bar 1. Also, inside both ear pieces 4 and 5,
A pair of stopper protrusions 1 that contact the upper portions of both shoulders of the eye portions 3 of the hanger bar 1, respectively, to prevent relative rotation thereof.
2, 13, 14, and 15 are formed. In the illustrated embodiment, stopper projections 12, 13, 14, 15
is formed inside both ear pieces 4 and 5,
It is sufficient if this is formed on either one of the ear pieces. Furthermore, on the outside of one of the ear pieces 4, a pair of opposing anti-rotation protrusions 16 for abutting against the head of the bolt 8 to prevent its rotation;
17 is formed.

In the hanger constructed as described above, the load of the overhead contact line T is received by the annular convex portions 10 and 11, and no load is placed on the bolt 8. Relative rotation of the ear pieces 4, 5 and the hanger bar 1 is prevented by stopper projections 12, 13, 14, 15.
Further, the eye portion 3 is reinforced by stopper protrusions 12, 13, 14, 15 that abut on both shoulders of the eye portion 3,
It does not easily deform even under tensile load.

As explained above, the present invention includes a hanger bar 1 having a hooking part 2 at the upper end that can be hooked to a suspension line M, and a hanger bar 1 attached to the lower end of this hanger bar 1 and holding a contact line T between them. Pair of ear pieces 4, 5
The hanger bar 1 is made of a round bar, has a bent eye portion 3 at its lower end, and has a pair of ear pieces 4, 5.
are attached with the eye part 3 sandwiched between them, and have bolt through holes 6 and 7 corresponding to the eye part 3 at centrally opposing positions, respectively, and the bolts are inserted through these bolt through holes 6 and 7 and the eye part 3. It is tightened by a bolt 8, and has annular protrusions 10, 11 on the inside of each ear piece 4, 5 that surround the bolt through holes 6, 7 and fit inside the eye part 3, and at least one ear The inner sides of the pieces 4 and 5 have a pair of stopper protrusions 12, 13, 14, and 15 that abut against both shoulders of the eye portion 3 and prevent relative rotation thereof, so that the structure is simple and easy to manufacture. This has the advantage that it is easy to obtain and can be obtained at low cost, and that a sturdy hanger can be provided.
