Description

Railway switch device

The present invention relates to a transmission device, and more particularly to a railway switch transmission device.

The Switch Machine is the power source for Turnout conversion and is the core component of the switch. According to different powers, the switch is divided into electric, pneumatic and oil pressure types, but electric switches are more common, and Taiwan is electric.

The lock of the electric switch is used to avoid improper unlocking caused by electromagnetic interference. Most of them use mechanical lock (Mechanical Lock), which has high safety. Under normal circumstances, the switch itself has the function of checking the tightness of the tip rail; once the "Unlock", the signal of the unsafe state is issued to limit the driving speed.

"The lock is locked" and "The lock should not be locked" is a normal safety check mechanism for the switch. However, in many cases, the failure of the switch is that the tip rail is closely related to the mechanical action. Normal, but it is a failure of "the lock is not locked."

Referring to FIG. 1 , the conventional switch system 1 includes a hollow housing 11 , a pull rod 12 movably disposed in the housing 11 , a motor 13 controlled to drive the pull rod 12 , and a A detector 14 for detecting the pull rod 12, a connecting rod 16 connected to a ramp, and a sensing rod 17 connected to the connecting rod 16 are detected. The motor 13 can controlly drive the movement of the pull rod 12, thereby pulling the track rail of the track to switch the train to travel on the main line or the branch line.

The detector 14 can detect the true position of the lever 12 by contact, thereby determining the current position of the track, thereby determining The train will then travel on the main line or the feeder line. The existing detector 14 detects the actual position of the rod 12 by contact detection to determine the actual position of the track, and uses the characteristics of the mechanical contact to switch the direction of rotation of the motor 13 to drive the rod. 12 do the push-pull movement before and after.

It can be seen from the above description that the sensing device of the conventional switch detects the rotation of the motor 13 and detects whether the pull rod 12 pushes or pulls back the movement of the tip rail on the driven rail. The connecting rod 16 is connected to the sensing rod 17. The detector 14 is provided with a sensor that can sense the position of the sensing rod 17 to detect the movement of the tip rail to ensure the safety of the train.

As far as high-speed rail is concerned, the abnormal alarms that have occurred since the previous switch include: the shackle is not positioned correctly, the rods are different... and so on. According to the information, the high-speed rail has been in operation for more than 30 times, with an average of less than two months. The Taiwan High-speed Railway has also worked hard to trace the root causes. However, many of the current problems require maintenance monitoring during the high-speed rail nighttime stop, but often no problem occurs during nighttime testing and maintenance. The maintainers are exhausted and there is no way to confirm the problem.

Since the high-speed rail converters are currently imported from Germany, the weather conditions in Taiwan and Germany are different, and the frequency of trains passing through the track is different. This causes problems when the converters imported from Germany are used in Taiwan. The time when the fault occurred was all during the day, but everything was normal during the night maintenance test. It is inferred that the weather in Taiwan is harsh and the vibration caused by the high-speed train is causing the "unlocked lock" signal.

How to deal with the existing switch that the lock is not locked, or has been locked but released the unlocked fault message, in the limited space in the switch and on the installed line, and does not affect The installation of detection and communication equipment under the operation of passengers is currently an urgent need.

Second, reduce troubleshooting time

When the switch C issues a fault message that "the lock is not locked" or "has been locked but released unlocked", the control group 51 can immediately pass the sensing group 61 and the photographing immediately. Group 62 confirms that the switch C correctly pushes the position of the rail. When it is confirmed that it has been locked but released an unlocked fault message, it can be confirmed as a false alarm, and the remote control group 51 can control the control. Group 71 resets the state of the switch C and then passes the train safely, which indeed reduces the time for troubleshooting.

Third, maintain the original structure of the switch

The novel uses a plurality of switches C to use the characteristics of a set of maintenance power sources, and the plurality of switchers C are not far apart from each other, which is very suitable for transmitting information by means of a power carrier, and can achieve information transmission without additionally adding an information transmission line.
