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
The present invention relates to a kind of device that is used for the contact wire of rectification (richten) aerial wire chain suspension, wherein, on a matrix, exist at least one by one first roller and one second pair of rollers that roller is formed, they are located at the phase opposite side of contact wire assigned position by the roller shaft that is arranged in parallel, be used to be undertaken on two contact wires between the roller driving surface, and wherein, second roller can move and fixing towards the direction of contact wire assigned position by setting device.
Background technology
By known a kind of this type of contact wire apparatus for correcting of EP1026026A1., establish two first rollers here, they and one central authorities movably second roller have the opposite effect.When contact wire is inserted, this contact wire by the application force of second roller that moves towards the contact wire direction and by the antagonistic force of first roller smooth (
) ().Second roller moves towards the contact wire direction by mandrel.
Make it smooth by correcting contact wire in opposed both sides.
Showed already that known devices may be towards angle of lateral inclination when rectification or smooth contact wire.This that surface that causes being contacted by pantograph trolley is not flattened aligning when having at least.In addition, smooth quality is especially also not high enough for express traffic.
Summary of the invention
Therefore technical matters to be solved by this invention is, a kind of device that is used to correct contact wire is provided, and has wherein got rid of roller shaft bevelled possibility in the formation process.
In addition, the technical problem to be solved in the present invention especially can be eliminated when running at high speed disturbing wave less in the contact wire, adopts hitherto known technology also can not accomplish this point.
The specific embodiment
Solved according to the characteristics combination of the above-mentioned technical matters of the present invention by claim 1.For this reason, establish anchor clamps on matrix, its chuck is located opposite each otherly, so that in both sides are engaged on two longitudinal slots of contact wire.
That is to say that the contact wire that is called groove line trolley wire commonly used has two grooves that extend longitudinally opposite each other, needs described groove in the aerial wire chain suspension for contact wire is fixed on.Should think these grooves are applied to pack into to horizontal location all the time roller shaft by measure of the present invention, and thereby make roller all the time in the contact wire up with below roll along it.
Employing according to the advantage that the described device of claim 1 of the present invention obtains is, recline ventricumbent that surface of the contact wire on it of the smooth reliably all the time pantograph trolley that railway vehicle arranged.
Having obtained an outstanding advantage is that the degree that contact wire can be high is smooth, because this installs the position that can not change it in formation process.Also eliminate very little ripple and thereby can no longer impel the generation radio.
Second technical matters also solved by the characteristics combination of claim 2.Here importantly, when having two pairs of rollers, in the listed formula Kn for first pair of rollers between 29 and 33, and for second pair of rollers that a/s sense of motion is in the downstream between 21 and 25.
If for example have the 3rd pair of rollers that is in the second pair of rollers downstream, then for the 3rd roller Kn between 14 and 17.
The advantage of bringing by selection Kn value is that contact wire can be smooth particularly well, to be used for express traffic.Even eliminate minimum ripple.
For example, stipulating in the described device by claim 2 for solving second technical matters, establish anchor clamps on matrix, its chuck is located toward each other with putting, so that in both sides are engaged on two longitudinal slots of contact wire.
Provide thus by a kind of combination of claim 1 with 2 described devices, it has all advantages of two kinds of devices.
From dependent claims, can learn by the favourable expansion design of claim 1 with 2 described devices.
For example, chuck has guide wheel, and their cooperations are engaged in the longitudinal slot exactly.Prevent stuck thus.
For example, the diameter of roller is selected according to the diameter and/or the intensity of contact wire.Guarantee special failure-free formation process thus.
For example, the thrust of roller in contact wire selected according to the diameter and/or the intensity of contact wire.Same thus assurance is smooth better.A kind of combination of these two kinds of relations also should be rational.
For example, two or more first and/or second rollers front and back are respectively one after the other laid, and the distance between the roller that lay in succession front and back is selected according to the diameter and/or the intensity of contact wire.
By being set, more a plurality of pairs of rollers can realize smooth better contact wire.But especially the roller of laying in succession before and after consider depends under the situation of special spacing of contact wire diameter, can advantageously reach better smooth.
By another example, at least one the 3rd roller and at least one the 4th roller are located at the opposite side of contact wire assigned position by the axle that is arranged in parallel, be used to be undertaken on two contact wires between the roller driving surface, wherein said at least one the 4th roller can move and fixing towards the direction of contact wire assigned position by another setting device.On the one hand the axle of first and second roller and on the other hand the 3rd with spool here being perpendicular to one another of the 4th roller.
Thus obtained advantage is that all right smooth contact wire of side direction consequently helps smooth lower surface.
The contact wire of correcting is for example with copper magnesium alloy or rhinemetal, or made by harder material.Listed fraction is particularly well suited to this hard or crash-resistant contact wire.
Employing obtains outstanding advantage according to the device that is used to correct contact wire of the present invention and is, all the time those surfaces that contact with pantograph trolley of smooth contact wire reliably.In addition, can eliminate in the contact wire reliably even little ripple, on pantograph trolley, generate radio thereby they are no longer impelled.
