Definitions

• the invention relates to a device for straightening a contact wire of a catenary, wherein on a base body at least one pair of rollers of a first and a second roller is provided, which are arranged with parallel angeord- Neten roller axes on opposite sides of the intended position of the contact wire for receiving the contact wire between the running surfaces of the two rollers and wherein the second roller to the intended position of the contact wire through an adjusting device is displaceable and fixable.
• Such a contact wire rectifying device is known from EP 1 026 026 A1.
• first two rollers pre ⁇ which counteracts an average displaceable second roller entge-.
• the contact wire is inserted, it is smoothed by the acting force of the second roller displaced towards the contact wire and by the counterforce of the first rollers.
• the second roller is moved by means of a spindle towards the contact wire.
• the invention is therefore based on the object to provide a Vorrich ⁇ tion for straightening a contact wire, in which a Tilting the roller axes during the smoothing process is excluded ⁇ .
• the object of the invention is, in particular, to eliminate disturbing relatively small waves in the contact wire during high-speed traffic, which was not yet possible with the hitherto known technology.
• a gripping device is arranged on the base body, the grippers of which are positioned opposite one another for engagement on both sides in two longitudinal grooves of the contact wire.
• a common contact wire which is referred to as Rillenfahrdraht, namely, has two opposing grooves extending in the longitudinal ⁇ direction, which are required for attaching the contact wire in the overhead line work.
• the inventive step lies in the fact that these grooves are used to DA, that the roller axles always assume a hori zontal ⁇ position and thus the rollers always run down and up along the contact wire.
• the advantage is achieved that is always reliably smoothed the downwardly directed surface of the contact wire to which the pantograph of a rail vehicle will rest.
• the contact wire can be smoothed to a very high degree, because the device during the smoothing process can not change their location, Even very small waves are eliminated and can no longer favor the sparking.
• the second object is also achieved by the feature combination of claim 2. It is important that with two existing pairs of rollers in the above formula Kn for a first pair of roles between 29 and 33 and for a in the provided direction of movement subsequent second pair of rollers between 21 and 25.
• this Kn is between 14 and 17.
• the advantage is achieved that the contact wire can be smoothed particularly well for high-speed traffic. Even very small waves are eliminated.
• a gripping device on the base body arranged, the grippers are positioned opposite each other for engagement on both sides in two longitudinal grooves of the contact wire.
• the grippers have guide rollers which engage precisely in the longitudinal grooves. This prevents jamming.
• the diameters of the rollers are selected as a function of the diameter and / or the strength of the contact wire. This ensures a particularly reliable smoothing process.
• the contact forces of the rollers on the contact wire are selected as a function of the diameter and / or the strength of the contact wire.
• a combination of these two dependencies is meaningfully possible.
• first and / or second ROI len each case arranged behind one another and the distances Zvi ⁇ rule successively arranged rollers depending on the diameter and / or the strength of the trolley wire selects ge ⁇ .
• the axes of the first and second rollers on the one hand and the third and fourth rollers on the other hand are perpendicular to each other.
• the contact wire to be straightened consists for example of a copper-magnesium alloy or a copper-tin alloy or of even harder materials.
• a hard or fixed contact wire said formula is particularly well suited.
