Description

A movable rigid catenary system

The present invention relates to a mobile rigid catenary system, more particularly, to a mobile rigid catenary system capable of efficiently moving a movable rigid catenary line with a small power, increasing the degree of freedom in design and construction, To a movable rigid electric cable system capable of stable electrical connection.

In general, electric railway is used by many people because of its advantages of quick, accurate and stable compared with other transportation methods. Moreover, recently, high-speed railway is widely used, and it is attracting attention as a safe and convenient public transportation means.

Electric railway, which has been attracting attention as a new transportation means in the 21st century along with the opening of high-speed railway, has recently been required to improve the performance, reliability and safety of electric railway lines due to speeding up of electric railway,

Here, a catenary line can be defined as a line including a catenary line for supplying electric power in contact with a current collecting device of a train that runs the line, and the facilities attached thereto.

Electric power required for traveling of a train is supplied through a power line and a collector of a pantograph of a vehicle. An electric line for supplying electricity to a train is classified according to a method of supplying electricity.

Specifically, the catenary line can be classified into an overhead catenary system and a third rail system, and the machined catenary line is divided into a rigid constriction system and a suspension system.

In this case, the suspension system is applied to the ground section in a manner that the line is guided by using a wire line. Since the line, the wire and the dropper line must be connected together and a peripheral device such as a tension control device is required, , It is difficult to apply it to the tunnel section because of its complexity.

That is, in order to apply the suspension bridge system to the tunnel section, the tunnel cross-sectional area must be increased so much that the construction cost is excessively increased. Also, since the installation space is narrow, daily inspection and maintenance are not easy.

The third railway type is advantageous in that it can be installed on a narrow space such as a tunnel by installing a power supply rail on the road surface or a side surface to supply electric power. However, since the power supply rail is disposed on the ground, It is dangerous and only applies to some special sections.

On the other hand, the above-mentioned rigid-body hitching system is constructed by integrating a catenary cable into a rigid body and installing it by using a separate structure such as a bracket. Thus, no tightening is required and a separate tension maintaining device is not necessary. .

In fact, the height of a rigid body line is about 90 to 120mm including a rigid body and a catenary line, and the total height of the contact between the collecting contact of the catenary line and the tunnel upper ceiling considering the support and electrical separation at low voltage (DC 750V or 1500V) Do.

Therefore, since the installation space of the rigid catenary line is small, it is possible to greatly reduce the construction cost in the new tunnel, and it is also advantageous in the maintenance work in the tunnel.

In Korea, a rigid catenary is called an R-Bar by reducing a rigid bar. A rigid catenary with a cross-sectional shape similar to that of a T-bar is especially called a T-Bar. Although the R-Bar is superior to the T-Bar in terms of workability and current collecting performance, it is widely used. In Korea, T-bar is applied to the DC section and R-bar is applied to the AC section.

These rigid-body electric wires are mounted on a common line in a state of being fixed by a support bracket or the like. However, this fixed cable system does not provide a sufficient work space for a series of operations related to the inspection and maintenance of the vehicle, the unloading of the cargo, and especially the work performed on the upper part of the railway car in addition to the running of the train, There is a high risk of safety accidents.

In consideration of the above-mentioned problems, a movable rigid electric cable is used in which the electric wire can be moved in the inspection hall and the storage yard where the maintenance and inspection work of the railway vehicle and unloading of the cargo are performed.

The movable rigid catenary supports the catenary using a movable bracket that rotates about a hinge, and the movable bracket is configured to move the rigid catenary while rotating by driving the motor.

When the railway vehicle stops at a certain position, the movable type of the electric wire turns the rigid electric wire so that the upper space of the railway vehicle can be operated without interference of the rigid electric wire.

In applying such a movable rigid line system, it is necessary to construct a structure for efficiently moving the movable rigid line with a small power, and to have a structure having a high degree of freedom in designing and construction so as to be adaptable to various construction environments desirable. And it is necessary to realize a stable electrical connection between the movable rigid catenary and the fixed rigid catenary.

Here, the railway vehicle sensing device 330 may be configured to detect the presence or absence of the electric locomotive 12 that tows the wagon 14 by a radar sensor, a photo sensor, a laser sensor, or the like. Of course, it is also possible to arrange to detect the wagon 14 rather than the electric locomotive 12.

As described above, when it is confirmed that the railway car 10 has been received in the inspection vessel, the pantograph 12a installed on the railway car 10 is lowered so that it can be checked whether the pantograph 12a has descended or not A pantograph sensing apparatus 340 may be provided.

The voltage sensing device 322 senses the voltage applied to the load side of the emergency disconnect device 320 of the mobile rigid electric cable system 1000 to detect an operator's electric shock accident that may occur due to a power failure, .

When the power-off is confirmed by the voltage sensing device 322, the movable bracket 100 moves and rotates for a subsequent operation, thereby moving the movable type solid body electric cable 50a from the connection position A to the separation position S .

This is because it is not possible to perform necessary work in a state where the movable rigid electric wire 50a is positioned at the connecting position A, that is, in the longitudinal direction at the center of the upper portion of the railway vehicle 10.
