Referring to FIG. 2, the tension adjusting device may be installed on a post installed along a track. The pulley device in which the tramline is wound may be fixed to the upper end of the post installed in the human section of the tramline. The pulley device may be connected to the tension shaft 203 in a downward direction based on the rotation shaft. Here, the tension shaft 203 is connected to the pulley device and the wire rope, it is possible to adjust the tension of the tram line.

Can be configured.

The reflective plate 202 may be disposed on a straight line in the vertical direction with the sensor 201, and may be fixed to a portion of the post at a height spaced apart from the ground on which the post is installed.

The sensor 201 may transmit a signal to the reflector 202 and receive a signal reflected by the reflector 202. In this case, the tension shaft 203 to which the sensor 201 is fixed may perform vertical movement by linear expansion of the tank line according to temperature change, and the sensor 201 may move up and down of the tension shaft 106. It is possible to perform the transmission and reception of the signal at the point where the position is moved.

In detail, (a) of FIG. 2, the tension shaft 203 may perform a downward movement as the amount of force applied to the tank line decreases as the tank line expands according to temperature change. That is, the tension shaft 203 may move in a downward direction in which the reflector plate 202 is located as the electric cable line connected to the tension shaft 203 is stretched.

The sensor 201 and the reflecting plate 202 fixed to the lower end of the tension shaft 203 has a length d1, and the present invention provides the sensor 201 and the reflecting plate fixed to the lower end of the tension shaft 203 by the expansion of the tramline. The sensor outputs a signal to the reflecting plate 202 to measure the length d1 between the 202 and the reflecting plate 202 reflects the incident signal, thereby measuring the length of d1 using the difference in the signal.

Referring to (b) of FIG. 2, the tension shaft 203 may perform an upward movement as the amount of force applied to the tank line increases as the tank line expands as the temperature changes. That is, the tension shaft 203 may move in a position above the reference position or the current position of the tension shaft 203 as the tank line connected to the tension shaft 203 is reduced.

In this case, the reflector 302 may have a structure in which diffuse reflection phenomenon occurs. Accordingly, the reflector plate 302 may reflect the transmitted signal in various directions regardless of the angle of the signal transmitted from the sensor 301.

In detail, the tramline in the human section is stretched in the form of a letter in the human section when the tension is changed according to the temperature change. The sensor 301 may transmit a signal in a straight line in the horizontal direction while being fixed to the side of the pulley device. In this case, as the tramline is stretched in the form of a letter in a state where the reflector 302 is fixed, the position of the reflector 302 may not exist on a straight line in the horizontal direction with the sensor 301. That is, the reflector 302 may not reflect the signal transmitted from the sensor 301 or reflect the signal in the direction in which the sensor 301 is not located according to the tension change of the stop line of the human section.

Thus, the present invention may include a reflecting plate 302 having a structure in which diffuse reflection phenomenon is generated to reflect a signal transmitted from the sensor 301 in various directions. The sensor 301 may receive a signal reflected from the reflector 302.

That is, the present invention may sense a signal for estimating the length of the pulley block and the reflector 302 as the position of the reflector 302 is changed due to the change in tension of the tram line in the human section according to the temperature change. In addition, the sensed signal may be transmitted to the central server through the communication device 204, thereby enabling real-time monitoring of the tension state of the catenary of the tensioning device fixed to each post.

That is, according to the present invention, by fixing the position of the sensor so that the sensor can be located in front of the light vehicle using the fixed plaque 500, the signal reflected from the reflector fixed to the parallel crevis of the human section can be more accurately received. Can provide the effect.

In addition, the other side 504 of the frame 502 may be secured with a communication device that transmits a signal to a central server. In other words, the fixed plaque 500 may be a mechanism for securing the communication device and the sensor to the side of the pulley arrangement.
