Embodiment Construction

[0022] exist figure 1 , the reference numeral 1 designates as a whole a part of a railway network for the passage of a known railway vehicle 2 moving on a track 3 and having a pantograph 4 which in use is integrated with the An overhead power supply line indicated at 5 slides in contact to power the railway vehicle 2 .

[0023] The overhead line 5 comprises a plurality of columns or gantries 6 , support cables 7 fixed to brackets carried by the columns 6 for suspension on the rails 3 , and contact wires 8 as they are known. The contact wire 8 has a free lower part 9 against which the pantograph 4 slides, and is connected to the support cables 7 by a plurality of hangers 10 . Conveniently, though not necessarily, the hanger 10 is in particular close to or in the area of ​​the column or portal 6, thus enabling the integration of already existing overhead line architecture.

[0024] The overhead line 5 also includes counterweights (not shown) to stretch the support cables 7 and...

Abstract

An aerial power supply railway line (5) has a plurality of hangers (10), each having, in turn, a fastening member (12) adapted to be fixed to a supporting element (7), a supporting frame (25) coupled to the fastening member (12), a fastening terminal (13) adapted to be coupled to a portion of a contact wire (8) with a pantograph (4) of a railway vehicle (2), a member (32), which is movable relative to the supporting frame (25) in opposite ways in a first direction (22) in the presence of an external disruptive action transmitted to the contact wire (8), and an elastic device (14) interposed between the member (12) and the terminal (13) and having elastic means (30) consisting of elastically deformable parts of the supporting frame (25); connecting rods (33) being provided between the movable member (32) and the elastically deformable parts (30) of the supporting frame (25).

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority from Italian Patent Application No. 102019000001731 filed on February 6, 2019, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a hanger supporting a suspended contact wire of an overhead power supply railway line and an overhead power supply railway line including the hanger. Background technique [0004] It is known that the electrical contact wires of overhead powered railway lines are supported by a plurality of hangers spaced apart from each other, wherein each hanger is suspended from a supporting wire and in turn carries the electrical contact wires suspended thereon. [0005] The pantographs of the train cars rest against the electrical contact wires in use to power the electric drive components of the train and, if necessary, other on-board equipment of the train. [0006] The hangers are conne...
