Description

[Detailed Description of the Invention] "Industrial application field" The present invention operates by obtaining information on the existence of a train to the section by dividing the section into appropriate sections by insulating the track and shorting the left and right rails with wheels. The present invention relates to a route locking circuit in a relay interlocking device for controlling the relay.

"Prior Art" For example, in a line section as shown in Fig. 2, a route locking circuit in a conventional relay interlocking device is generally as shown in Fig. 3.

In other words, according to the section divided by insulation as shown by the symbol in FIG. 2, the main line X-
A route locking relay 1TRSR for securing the Y route and a quince relay 1RUR for securing the lane Z route are provided.

Then, in order to secure the route sequentially, the action contact points ATRSR1, BTRSR1, 1TR1 corresponding to each route and the action contact point 1KR1 for indicating the localization of the turning machine 1 are provided for the route lock relay 1TRS.
It is connected in series with R. Operating contact 1KR1 is a rolling machine 1
It is closed when is located on the main line side, and opened when it is in the inverted position.

Tokime relay that secures an approach route from side line Z to main line Y
1RUR is provided by branching from a line in series with the route lock relay 1TRSR, and the operating contact 1RUR1 of the hour relay 1RUR is the operating contact 1KR.
Connected in parallel to 1. The operating contact 1RUR1 moves immediately when opened, but operates after a predetermined time when closed.

When the train takes the route from the X point to the Y point, the operating contacts ATRSR1,1TR1 are restored and opened one after another according to the progress of the train, and the power to the route lock relay 1TRSR is cut off, which causes the route lock. The relay 1TRSR turns off the power of the control relay of the rolling machine 1 to lock the route.

Then, when the train reaches the section CT, all the operating contacts arranged in series are closed, and the track locking relay 1TRSR operates to connect the power supply to the control relay of the rolling machine 1 to enable the operation and lock the path locking. To release.

In addition, when the train progresses from the Z point and enters the main line,
The rolling machine 1 is switched to the inverted position, and the operation contact 1KR1 is opened to display the inverted position. Since the operating contacts except the operating contact 1KR1 are closed when the rolling machine 1 is simply switched, the hour relay 1RUR is energized and its operating contact 1R
The route lock relay 1TRSR is energized by UR1 and the route lock is not performed.

When the train takes the route from section BT to section 1T, the wheels will short-circuit the left and right rails to open the operating contacts BTRSR1,1TR1, and the operating contact 1RUR1 of the hour relay 1RUR will open to open the route lock relay 1TRSR. The power is cut off, and thus the route locking relay 1TRSR turns off the power of the control relay of the turning machine 1 to lock the route.

When the train exits section 1T and enters section CT, the operating contact point BTRS
R1,1TR1 is closed, current relay 1RUR is energized to start operation, and after a lapse of a predetermined time, operation contact 1RUR1 is closed and power is applied to path locking relay 1TRSR to unlock the path locking.

The reason why I have placed the KIME relay 1RUR is that if this is a relay that moves immediately, if a short circuit failure occurs in the section 1T, it will be mistakenly recognized as a train missing in the section CT and the route lock will be released. .

[Problems to be solved by the invention] However, in such a conventional technique, since it is necessary to branch from the energization path to the path locking relay and to separately provide a time relay, not only the circuit becomes complicated but also However, there was a problem that extra time relays were required, and the cost increased due to the number of installation man-hours.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a path locking circuit in a relay interlocking device that simplifies the circuit and reduces the cost.

[Means for Solving the Problems] The gist of the present invention for achieving such an object is to insulate the railroads and divide them into appropriate sections, and trains to the section by shorting the left and right rails with wheels. It is a route locking circuit in a relay interlocking device that controls the operation by opening and closing the rolling machine (1) by obtaining the existence information of the main line and the side line from the side line. When taking the route to enter the main line, to prevent the rolling machine (1) from operating irrespective of the short-circuit failure on the side line, when entering the main line from the side line, the left and right rails should be disconnected after the short circuit has been broken. The track chain that locks and unlocks the rolling machine (1) for the period of time, and is connected and disconnected when the train enters and leaves the railroad section that includes the junction from the side line to the main line. Lock relay (1TRASR) and the track lock relay (1TR ASR) has a rolling machine (1) that opens and closes, and the track locking relay (1TRASR) is a train passage time during the track locking operation when securing the track from the side line to the main line. The rolling machine (1) is provided with an output terminal that operates with a sufficiently long predetermined time and, on the contrary, outputs a lock release output so as to move immediately when securing the course of the main line. Path lock relay (1TRAS
(R) output terminal is connected, when securing the route from the side line to the main line, receive the output of the output terminal, and lock the route only for a predetermined time sufficiently longer than the transit time of the train,
It exists in the route locking circuit in the relay interlocking device, which receives the output from the output terminal for instructing immediate operation when the route of the main line is secured, and releases the route locking operation immediately after passing the train.

"Operation" The rail is insulated and divided into appropriate sections, and the relay interlocking device locks the rolling machine or the like according to the route determination information to secure the route. Then, the existence information of the train to each section is obtained by short-circuiting the right and left rails by the wheels, and the route lock is sequentially set, while the route lock is released as the train passes.

As long as the train is traveling on the main line, a short circuit failure due to wheels cannot occur. Therefore, when the train passes through the required section of the route lock, the contacts operating in the lock are immediately released to release the route lock.

When the main line and the side line are merged and the route to enter the main line from the side line is taken, a release operation from the route lock relay is performed after a certain period of time has elapsed since the short circuit of the left and right rails due to the wheels disappeared. Output is made and the route lock is released.

If a short circuit failure occurs while advancing on a side track, it may be mistaken for a train not to exist in the section. Since the release operation is output with the time element, if this predetermined time is set to a time sufficient for the train to pass through the lock section, the lock will be released after the passage and no malfunction will occur. .

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention. For the sake of clarity, the same parts as those of the conventional example will be described with the same reference numerals.

As shown in FIG. 2, the railroad track consisting of the main line XY and the side line Z is enclosed in parentheses, and the section AT having the branch line, the section BT having the branch line and the section line BT having the branch line, and the side line Z are the main line. The section where the turning machine 1 is installed at the point where it merges with XY
It is divided into 1T and the section CT that passed the rolling machine 1. A rollover machine A is installed in the section AT where the branch lines join, and a rollover machine B is similarly installed in the section BT.

The relay interlocking device for managing the train passing through the point of the turning machine 1 where the main line and the side line meet has a route locking circuit as shown in FIG.

Path locking relay 1TRA for path locking by the turning machine 1
SR is provided, and various contacts are provided for disconnecting and energizing the path locking relay 1TRASR to release or set the path locking operation.

In order to secure the course sequentially, the operation contact ATRSR1 is provided corresponding to the section AT, and the operation contact BTRS corresponding to the section BT.
R1 is provided, and operating contacts 1TR1 are provided in series corresponding to section 1T.

The end of the line connecting the operating contacts in series branches into two paths, one path L1 is directly connected to the route locking relay 1TRASR, and the other path L2 is the position securing indication of the turning machine 1. It is connected to the track lock relay 1TRASR via the operating contact 1KR1. The operating contact 1KR1 is closed when the rolling machine 1 is in the orientation on the main line side and is opened when it is in the inverted position.

The route lock relay 1TRASR operates with a certain time period when energizing from the route L1 which is the time of the route lock operation when securing the route from the side line Z to the main line XY, and conversely the route of the main line. When the power is supplied from the route L2, which is the time when the power supply is secured, an output that immediately moves is provided. The output is naturally connected to the rolling machine 1.

 Next, the operation will be described.

Operation contact ATRSR1, B when the path lock is not performed
TRSR1,1TR1,1KR1 are all operating and closed, and the route lock relay 1TRASR is energized from the route L2. The operating contact 1KR1 is closed as long as the train follows the route of the main line.

When the train takes the main route from the point X to the point Y, the operating contacts ATRSR1,1TR1 of each route are restored and opened one after another according to the progress of the train, and the power to the route lock relay 1TRASR is cut off. As a result, the route locking relay 1TRASR locks the route by turning off the power of the control relay of the rolling machine 1.

When the train passes the section 1T and reaches the section CT, all operating contacts ATRSR1, BTRSR1, 1TR1, 1KR1 closed in series, energize the route lock relay 1TRASR from the route L2, and roll by the output immediately A power supply is connected to the control relay of the machine 1, and it becomes operable. That is, the route lock is released.

Next, when the train progresses from the Z point and enters the main line, the turning machine 1 is switched to the inverted position, and the operating contact 1KR1 is opened to display the inverted position. Since the operation contacts other than the operation contact 1KR1 are closed simply by switching the turning machine 1, the path locking relay 1TRASR is still energized by the path L1 and the path locking is performed. Not not.

When the train takes the route from section BT to section 1T, the wheels short-circuit the left and right rails to open the operating contacts BTRSR1, 1TR1 and the power to the track locking relay 1TRASR is cut off, and the track locking relay 1TRASR The power of the control relay of the rolling machine 1 is turned off by the output that moves immediately to lock the course.

When the train exits section 1T and enters section CT, the operating contact point BTRS
R1 and 1TR1 are closed, and the route lock relay 1TRASR is energized from route L1. When electricity is supplied from the route L1, the output that operates with a certain time for a predetermined time is output to the turning machine 1, so that the route lock is released after the predetermined time has elapsed.

Since the side line Z does not pass through the trains very often, a short circuit failure may occur due to the insulating action due to rust or the like even if the wheels pass through. If a short circuit failure occurs in the section 1T, the operating contact 1TR1 is restored and closed, and the path locking relay 1TRASR is energized from the path L1.

As described above, when the route lock relay 1TRASR is energized from the route L1, the restraint output is output to the turning machine 1 after a lapse of a predetermined time with a time element, so a time sufficiently longer than the passable time is set. If this is done, the route lock will not be released even though the train is still in the lock section.

In addition, the contact of the embodiment is not limited to the contact contact,
It also includes the parts that are connected and disconnected by a so-called non-contact relay that connects and disconnects without making contact, and the H and L outputs of computer signals.

[Advantage of Device] According to the path locking circuit in the relay interlocking device according to the present invention, either the immediate operation or the chronological operation can be performed depending on the input path to the path locking relay. By providing an output to control the progress of the train train on a railroad track having a side track and a main track, the number of relays used in the circuit can be reduced and the circuit can be simplified, simplifying the installation. Together with this, it is possible to reduce costs.
