BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anti-

The present invention relates to an apparatus for preventing uneven wear of a catenary, and more particularly, to an apparatus and method for preventing uneven wear of a catenary line, and more particularly, to a catenary catheter that is supported by an R-BAR bracket provided on a catenary line of a curved section, So that the contact between the rigid body electric line and the current collecting device is maintained in an optimal state corresponding to the inclination of the curved line to the electric cable, The present invention relates to an apparatus for preventing uneven wear of a catenary by preventing an accident such as a pantograph burnout by preventing an uneven wear of the provided catenary line, thereby extending the service life and suppressing arc generation in an expansion device.

In general, electric railway has many advantages such as speed, accuracy, safety, mass transport, comfort, low pollution, etc. compared with other transportation means. Therefore, electric railway is a pivotal in logistics between major industrial facilities and passenger transportation between big cities And the usage is continuously expanding not only in domestic but also in the world.

Electric cars used in electric railways are operated through electric power supplied from outside. Electric car lines are installed in the section where electric car is operated, and electric car lines that supply electric power in accordance with contact with a pantagraph fixed to an electric car The electrical conductivity (rate), heat resistance, arc resistance, corrosion resistance, and abrasion resistance must be excellent due to the characteristics of continuous contact with the current collector.

Such an electric railway necessarily forms a straight section and a curved section depending on the terrain or path environment, and stable management in the curved section is the most important factor for safe operation due to the nature of the electric railway. Therefore, The management of tram lines is a very important factor in railway operation. In other words, it is a very important factor for stable operation that the contact line between the electric cable line, which is a facility for supplying electric power necessary for the electric vehicle, and the electric current collecting device provided in the electric vehicle are stable.

Generally, the curved section is provided with a cant so that the safe operation of the train can be performed. The cant is designed so that the outer rail is raised at a high level relative to the inner rail so that the railway vehicle can smoothly pass through the curved point And keeps the outer rail of the curve section higher than the inner rail in order to draw the gravity to the center of the orbit, thereby preventing the departure of the train by centrifugal force at high speed operation.

FIG. 1 is an enlarged cross-sectional view of an electric vehicle and a rigid body line in order to show the state of loss of the electric wire due to the uneven wear, in which an electric wire 60 supported by an R-BAR bracket 50 is vertically The electric current collector 70 is tilted by the inclination by the cant of the curved section while the electric current collector 70 is supported and fixed and the current collector 71 is also in contact with the electric wire 60 in a tilted state. 1, there is a problem that an uneven wear phenomenon inevitably occurs in the catenary 60 as shown in an enlarged view when the vehicle is driven for a long period of time.

That is, the current collector 71 of the electric vehicle 70, which moves in an oblique slant state in a state in which the rigid electric wire, which is rigidly fixed to the R-bar bracket and is connected to the electric wire 60, It can be seen that the catenary line 60 is unevenly worn by the contact with the catenary line 60, and an uniaxial loss 63 is generated in the catenary line 60 as shown in the enlarged view. More specifically, the enlarged view 61 is a fixed portion fixed to a rigid body, 62 is a worn portion of the catenary, and 63 is a loss portion due to the uneven wear.

Such an uneven wear phenomenon shortens the life of the catenary cable. If the expansion joint (Expansion Element) is not installed parallel to the raceway surface, there is no cant adaptation function when passing through the current collector. There is a problem that the lifetime of the current collector is shortened due to the electrical wear caused by the generation of the arc.

As a conventional technique for solving the problem of uneven wear in the curved section of such a catenary, Japanese Laid-Open Patent Publication No. 1998-065090 (published on Oct. 10, 1998) is disclosed. Fig. 2 is a cross- And shows a pulling device 10 installed so as to pull the electric wire that comes into contact with the pantograph of the electric vehicle and supplies electric power to the electric vehicle in a curved section.

The pulling device 10 includes an insulating insulator 3, a feeder line 4, a V-dropper 5, a wire 6, an ear 11 to be clamped to the electric wire 7, An angle 21, an insulator 22 provided on the ear 11 and the support angle 21 for insulation, and a curved pulling metal fitting 17 formed of an aluminum alloy tube. The curved pulling metal fitting 17 ) Is made of an aluminum alloy tube, and at both ends, a connector made of copper or aluminum alloy (bronze) is fixedly installed.

A hinge fixture having a screw portion at a distal end portion and a hinge engaging portion to which a hinge pin is to be inserted is hingedly coupled to one end of the curved pulling metal fitting 17 by a hinge pin. A pair of clips having a wire holding portion and a wire clamping portion for clamping the wire 6 and the wire 7 at predetermined intervals are inserted and fixed as bolts.

The other connecting end 18 of the curved pulling metal fitting 17 is connected and fixed to the supporting angle 21 provided on the inner wall of the tunnel by the loop 20 so that the other end of the curved pulling metal fitting 17 is insulated And is installed in the support angle 21. Therefore, the tilting of the catenary line (7) is adjusted in accordance with the cant slope so that the phenomenon of uneven wear can be prevented.

In the case of the above-described conventional bracket, it is possible to rectify the tram line phenomenon by the cant into the curve to some extent through the curved pulling bracket, but in a state where there is no curved bracket in the R-bar bracket And a hanger clamp fixes the R-Bar bracket and the electric wire is fixed to the R-Bar bracket, the R- Bar) brackets are always supported in a horizontal state under the support bracket, there is a problem in that the wire cant constantly generates uneven wear on the wire.

If the uneven wear phenomenon continuously occurs on the catenary line, the life span of the catenary line is reduced and the maintenance cost increases. Also, the tilt adjustment of the catenary supported by the R-bar bracket for the cant of the curve section There is a fatal problem in safety operation because it is impossible.

In other words, the life of the catenary line is shortened due to the uniaxial machining, and the replacement cycle becomes faster, which leads to an increase in the cost loss. In addition, an accident may occur due to the pantograph burning due to the arc generation in the expansion device There is a problem.
