Embodiment Construction

[0007] The above-mentioned technical problem is solved according to the invention by the combination of features of claim 1 . For this purpose, clamps are provided on the base body, the jaws of which are positioned opposite one another in order to engage on both sides in the two longitudinal grooves of the contact conductors.

[0008] That is to say, the conventional contact conductors known as grooved conductors have two oppositely extending grooves in the longitudinal direction which are required for fastening the contact conductors in the overhead conductor chain suspension. The measure according to the invention is to be understood as the use of these grooves for mounting the roller shaft always horizontally and thus always rolling the roller above and below the contact wire along it.

[0009] The advantage obtained with the device according to claim 1 of the invention is that the downwardly facing surface of the contact conductors on which the pantograph carrier of the ra...

Abstract

The invention relates to a device for fixing a contact wire of an overhead line catenary. At least one pair of rolls consisting of a first roll and a second roll is provided on a base body, said first and second rolls being arranged on opposing sides of the determined position of the contact wire with parallel axes in order to receive the contact wire between the running surfaces of the two rolls. The at least one second roll can be displaced in the direction of the determined position of the contact wire by means of a displacement device, and fixed. According to the invention, a gripping device is arranged on the base body, the grippers thereof being arranged opposite each other in order to grip the contact wire on both sides in two longitudinal channels. The dependence of the application force of the rolls and of the resistance of the contact wire corresponds to the formula Kn = (Sn . f): (L . B . A) where Kn represents between 29 and 33 for a first pair of rolls, between 21 and 25 for a second pair of rolls, and between 14 and 17 for a third pair of rolls.

Description

technical field [0001] The invention relates to a device for the straightening (richten) of contact wires suspended by chains of overhead conductors, wherein on a base body there is at least one pair of rollers consisting of a first roller and a second roller arranged in parallel The roller shaft of the first roller is arranged on the opposite side of the specified position of the contact wire, and is used to receive the contact wire between the two roller working surfaces, and wherein the second roller can be moved and fixed in the direction of the predetermined position of the contact wire through the adjustment device. Background technique [0002] A contact wire straightening device of this type is known from EP1026026A1. Here, two first rollers are provided, which counteract a centrally movable second roller. When the contact wire is inserted, the contact wire is smoothed (gltten) by the active force of the second roller moving in the direction of the contact wire and...
