Description

A movable rigid catenary system

More particularly, the present invention relates to a movable rigid wire system, and more particularly to a movable rigid wire system which can reduce the time and cost associated with the installation of a plurality of control wires, prevent a malfunction due to weak control signal output And more particularly,

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.

When a control system is constructed by a general central control method for controlling the movable rigid cable system, a control line must be connected to each of the protection devices for protecting the driving device and the system. Therefore, time and cost As the control line becomes longer, the output of the control signal becomes weaker, resulting in a problem that a malfunction occurs.

Therefore, there is a need for a movable rigid wire system that can save time and cost due to the installation of a large number of control wires, and prevent a malfunction from occurring due to weak control signal output as control wires become longer.

Embodiments of the present invention seek to reduce time and cost associated with installing a plurality of control lines.

Also, as the control line becomes longer, the output of the control signal is weakened to prevent a malfunction from occurring.

According to an aspect of the present invention, there is provided a catenary catheter including: a fixed rigid catenary line connected to a catenary line; a movable rigid catenary line selectively connected to or separated from the rigid rigid catenary line; And a movable bracket connected to or separated from the stationary rigid line by selectively moving the movable rigid line to a connecting position for connecting the movable rigid line to the pantograph of the railway car and a separating position for separating the movable rigid line, At least one protective device for protecting the catenary system; A plurality of local controls for generating a control signal for driving the movable bracket and for controlling the protective device; And a main control unit connected to the local control unit through a communication line and directly controlling the local control unit.

The movable bracket may include a first movable bracket capable of being actively pivotally connected to the driving motor, and a second movable bracket for manually rotating together as the first movable bracket rotates.

The local control unit may be disposed in a steel pipe where the first movable bracket is installed.

The protection device may include a voltage supply unit for selectively supplying or blocking electricity to the movable rigid electric wire, and a voltage sensing device for sensing whether electricity is supplied from the voltage supply unit.

The protection device may include a railway vehicle sensing device for sensing the presence or absence of a railway vehicle on the movable rigid electric wire.

The protection device may include a pantograph sensing device for detecting the rising and falling of the pantograph to prevent the collision with the pantograph in accordance with the movement of the movable rigid wire.

The protection device may include a moving object interference detection device for preventing a collision between the movable rigid line and the moving object.

Embodiments of the present invention can save time and cost by installing a plurality of control lines.

Also, as the control line becomes longer, the output of the control signal becomes weaker, and malfunctions can be prevented from occurring.

[

The movable connection member 80 and the movable connection member 90 form a stable electrical connection between the movable rigid-body electric cable 50a and the rigid fixed-electrode electric cable 50b.

Referring to FIGS. 1 and 6 to 14, the installation and control structure of the movable bracket 100 will be described.

The movable rigid catenary line 50a is supported by the movable bracket 100 and connected to the pantograph 12a of the railway car 10 on the section M provided with the movable rigid line 50a, Can be selectively moved to the connecting position A (see Figs. 16 and 17) and the separating position S (see Figs. 16 and 17), respectively.

The movable bracket 100 may be supported by the steel pipe 199 and be positioned at a predetermined height. A plurality of the movable brackets 100 may be installed at regular intervals along the longitudinal direction in which the movable type steel body line 50a is installed.

In this embodiment, as the plurality of movable brackets 100 simultaneously rotate in the same direction, the movable rigid-field electric cable 50a can be moved to the disengagement position S. As the plurality of movable brackets 100 rotate simultaneously in the opposite direction, the movable rigid electric cable 50a can be moved to the connection position.

At this time, the movable bracket 100 rotates on the horizontal plane to move the movable rigid catenary 50a. In this case, since the drive motor 160 is burdened to the gravity direction load of the movable rigid catenary 50a, the drive motor 160 having a large power .

The movable bracket 100 includes a first movable bracket 100a directly connected to the driving motor 160 and capable of pivotally moving, and a second movable bracket 100b which is manually rotated together with the first movable bracket 100a 2 movable bracket 100b.

As shown in FIGS. 10 and 11, the first movable bracket 100a is actively rotatable about the hinge portion 101 by providing the driving motor 160 with the driving force.

Since the second movable bracket 100b is connected to the movable rigid electric wire 50a, the first movable bracket 100a is manually rotated about the hinge 101 as the first movable bracket 100a rotates.

The first movable bracket 100a and the second movable bracket 100b may be alternately installed as shown in FIGS. 6 and 7, or may be arranged such that the first movable bracket 100a is disposed at regular intervals as shown in FIG. 14 Can be installed.

12 is a stationary bracket 100c which is installed in the section G of the fixed type of the solid body line 50b and serves only to fix and support the fixed type body line 50b without rotating.

Meanwhile, the length of the movable bracket 100 according to an embodiment of the present invention is variable. The movable bracket 100 includes a guide member 120 having a hollow inside and a moving member 130 movably in an inward direction of the guide member 120 so that the length can be varied .

Specifically, the hinge unit 101 is connected to the main frame 100 and the main frame 100 is connected to the guide member 120. A hollow is formed inside the guide member 120, and the moving member 130 is movably provided on the inner hollow of the guide member 120.

A plurality of fixing holes 132 are formed along the longitudinal direction of the moving member 130 so that a fixing member 124 such as a bolt or a pin member penetrates the through hole 122 of the guide member 130 The moving member 130 can be fixed by being inserted into the fixing hole 132.

Accordingly, since the length of the moving member 130 protruding outside the guide member 120 can be adjusted, the length of the entire movable bracket 100 can be adjusted as desired.

An insulating member 140 is connected to the moving member 130 and a fixing portion 150 is provided at an end of the insulating member 140 to fix and support the supporting clamp 200. And the rigid electric wires 50a and 50b fixed to the support clamp 200 can be supported at a certain height.

10 and 11, the first movable bracket 100a and the second movable bracket 100b are formed in the same manner, and the fixing bracket 100c shown in FIG. 12 also does not rotate The first movable bracket 100a, the second movable bracket 100b, and the fixed bracket 100c can be configured to be variable in length.

By configuring the movable bracket 100 so as to be variable in length, it is possible to secure freedom in designing and construction so that it can be fitted to various construction environments in different places.

Protection devices for protecting the mobile rigid cable system 1000 will be described with reference to FIGS. 1 and 15 to 17. FIG.

First, a railway vehicle sensing device 330 may be provided to sense whether the railway vehicle 10 has entered the inspection hall or the container yard.

The railway vehicle sensing device 330 is configured to sense whether the railway vehicle 10 has arrived at a predetermined position, that is, whether there is an electric locomotive 12 that tows the wagons 14 at the corresponding position, It is possible to prevent the catenary line 50a from being connected and disconnected in advance.

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 pantograph sensing apparatus 340 senses whether the pantograph 12a has been lowered so as to prevent the pantograph 12a from being displaced upward when the movable rigid catenary 50a moves thereafter .

That is, the pantograph detection apparatus 340 protects the movable rigid catenary 50a and the pantograph 12a by preventing the separation of the pantograph 12a due to the rotation of the movable rigid catenary 50a.

Since the voltage applied to the pantograph 12a is high, it is preferable to use a non-contact type radar sensor, a photosensor, a laser sensor, or the like as the pantograph sensing device 340.

Meanwhile, the movable type solid electric cable 50a is provided with a power supply unit 320 for selectively supplying or blocking electricity. The quarry unit 320 may be installed on a column 321 located at one side of the inspection unit and may be installed at a lower portion of the column 321 together with a control unit 323. [

When the railway car 10 is put in the inspection port, the power is cut off from the power feeding device 320 and then the pantograph 12a, which is a current collecting device, is lowered. 340 senses whether the pantograph 12a has fallen or not.

At this time, a voltage sensing device 322 may be provided to sense whether electricity is supplied from the electricity-receiving unit 320. 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.

After the movable rigid transmission line 50a moves to the separation position S, necessary work is performed. For example, in the container yard, the loading operation of the container 14a loaded on the wagon 14 proceeds. At this time, a moving object interference detecting device 350 may be further provided to prevent a collision between a moving rigid catenary 50a and a moving object such as the container 14a when unloading the container 14a.

The moving object interference detecting apparatus 350 prevents the collision between the moving rigid catenary 50a placed at the separation position S and the moving object or the container 14a to prevent the container 14a and the movable rigid catenary 50a And may include port or wye length sensors installed in the same longitudinal direction as the movable rigid catenary 50a to sense such interference.

A control system for controlling the driving and protecting devices of the movable bracket 100 will be described with reference to FIGS. 1 and 6 to 17 as follows.

The main control unit 430 is connected to a plurality of local control units 440 through the wired router 430. The plurality of local control units 440 are installed in the control box 432 under the steel pipe stock 199 provided with the first movable bracket 100a and are connected to the main control unit 430 and the control unit 430 through the communication lines 401 and 403, Can be connected.

The communication lines 401 and 403 are installed through a connection line 407 connected to the control box 432 and an embedded line 405 to connect the main control unit 430 and the local control unit 440.

The local control unit 440 may include a protection device such as the driving motor 160 and the railway vehicle sensing device 330, the pantograph sensing device 340, the voltage sensing device 322, the moving object interference sensing device 350, And a control line (not shown), and can generate necessary control signals to drive or control each device.

The main control unit 430 may be configured to directly control only the local control unit 440 through only the communication lines 401 and 403.
