Description

An Apparatus For Solving Snow Of Rail Turnout And Method Thereof}

The present invention relates to an apparatus for melting track branches and a method thereof. More specifically, when snow is detected around the track branches and one of the temperatures of the track and the atmosphere is below the set temperature, the heating unit is operated to close the eyes of the track branches. The present invention relates to a track branch snow melting apparatus and a method for preventing an accident that may occur when a train branches a track by melting.

1 is a diagram illustrating the structure of a track branch.

The track turnout part is installed at a part where the track is separated or joined in two directions. As shown in FIG. 1, the track branching portion includes a point portion, a lead portion, and a crossing portion.

The point part selects which track to enter the vehicle from two or three tracks. The rear end of the toe rail is a heel, and the toe rail turns around, and the tip is bonded to the basic rail. Drive on the rails. It is advantageous to have the point strength as large as possible within the limitations of the building in a structure in which the point portion is cut by thinly cutting a conventional rail to be in close contact with the basic rail.

The lead part is located between the point part and the crossing, and guides the train to the toe rail.

The crossing portion is a portion where the gauge lines cross each other, and is composed of a V-shaped north rail and an X-shaped wing rail.

In other words, the rail is mounted at the fork in the track and the train adjusts it to correct the trajectory of the train. However, if the snow falls in winter and the snow accumulates between the base rail and the tongue, the rail will not stick to the base rail and the train will not turn.

A method for solving this problem is presented in Korean Patent Laid-Open No. 2001-0106285. The patent has a temperature sensor for measuring the temperature of the rail and an eye detection sensor capable of recognizing the presence of the eye between the tongue and the fixed rail is determined that there is an eye between the fixed rail and the tongue rail Disclosed is a snow melting apparatus that drives a heater to melt snow.

However, according to the above method, since the eye sensor is located between the fixed rail and the tongue rail, the eye sensor may be damaged when the railroad is running.

In addition, when the temperature of the rail is below a certain temperature by measuring the temperature of the rail, the snow melting device is driven. When the rail is running, the temperature of the rail often rises, so snow exists between the fixed rail and the tongue rail, but the temperature of the rail In many cases, there was a problem that the actual snow melting device does not operate in many cases.

 Therefore, there is an increasing demand for a snow melting apparatus and method capable of overcoming such an unreasonable problem of the conventional snow melting apparatus and capable of removing snow more efficiently.

The present invention has been made to solve the above problems, the first object of the present invention is to remove the snow present in the track branch, the track branch snow melting that can prevent the risk factors at the time of the branch of the train in advance It is to provide an apparatus and method.

It is a second object of the present invention to provide an apparatus and a method for melting line branch parts that can prevent waste of electric power by driving a heating part only when the temperature is below a certain level using a temperature sensor.

It is a third object of the present invention to provide a track branch snow melting apparatus and method which can more reliably remove snow by driving a heating unit using two temperature sensors.

According to the first aspect of the present invention for achieving the above object, in the track branch snow melting apparatus, the snow detection is located at a predetermined distance away from the track branch in a direction toward the outside of the track, detecting the snow of the area within a certain distance A reference temperature setting unit configured to set a lower temperature as a reference temperature among a sensor, a first temperature sensor detecting an atmospheric temperature, a second temperature sensor sensing a temperature of a rail, and a temperature detected by the first temperature sensor and the second temperature sensor And a heating unit installed inside the rail and generating heat, and a driving unit for operating the heating unit when a snow detection signal is received from the snow detection sensor and the reference temperature is lower than or equal to a preset first set temperature. A track branch snow melting apparatus may be provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a configuration diagram of a track branch snow melting apparatus according to the present invention. As shown in FIG. 2, the track branch snow melting apparatus includes a snow detection sensor 40, a first temperature sensor 60, a second temperature sensor 50, a reference temperature setting unit 70, a driver 80, and It is comprised including the heating part 90.

The snow detection sensor 40 is a sensor that detects snow in an area within a predetermined distance from the track branch in a direction away from the track branch, and the snow detection sensor 40 is mainly located at a height of about 50 cm from the ground. It is desirable to. Therefore, in the present embodiment, the snowfall detecting sensor 40 is provided near the outside of the track without being disposed between the tracks or on the track. The snow detection sensor 40 is mainly a reactance sensor. A reactance sensor has a parallel plate capacitor formed of a pair of metal plates disposed oppositely. When snow is present between the metal plates, the capacitance of the capacitor is changed by the change of the dielectric constant, and the current is changed accordingly, so the presence of snow is detected by measuring the current change. Since the actual snow is not placed only between the parallel plates, the snowfall detection sensor 40 is provided with a heater to melt the snow to form a contact by forming a liquid. However, the present invention is not limited to the reactance sensor as the snow detection sensor 40, and various other detection sensors may be used.

The first temperature sensor 60 is a sensor for detecting the temperature of the atmosphere, the second temperature sensor 50 is a sensor for detecting the temperature of the basic line 10 around the tongue rail 20.

The temperature sensor utilizes the characteristic that the electrical resistance of the conductor changes with the change of temperature. By using these characteristics, if the change rate of resistance to unit temperature change is known, the corresponding temperature can be measured only by the variable resistance value. Here, the rate of change of resistance with respect to the unit temperature is called the temperature coefficient, and if the resistance increases with increasing temperature, the positive temperature coefficient is called the negative temperature coefficient when the resistance decreases. The metal used mainly for temperature measurement has a positive temperature coefficient. Among them, the material used for temperature measurement is platinum, nickel, copper, etc. The pureer the material, the larger the temperature coefficient becomes and the value becomes constant. Such temperature sensors are generally divided into contact sensors and non-contact sensors as a measuring method.

The reference temperature setting unit 70 receives a signal sensed by the first temperature sensor 60 and the second temperature sensor 50 and sets a lower temperature among the two temperatures as the reference temperature. In other words, the track can be somewhat hotter by the frictional force as the train passes, and can therefore be significantly above ambient temperature. Therefore, there may be a case where there is snow between the basic rail 10 and the tongue rail 20 because the temperature of the track is high but the temperature of the air is low. Therefore, in the present invention, both the atmospheric temperature and the line temperature are measured and the lower temperature is set as the reference temperature.

The driving unit 80 is to operate the heating unit 90 when the snow detection signal is received from the snow detection sensor 40 and the calculated reference temperature is equal to or less than the first preset temperature. Here, the first set temperature can be arbitrarily set, but the range of 0 to 5 ?? is appropriate. The driving unit 80 stops the operation of the heating unit 90 when the temperature of the line is increased due to the heat generated by the heating unit 90 so that the temperature is higher than or equal to the second preset temperature. Here, the second set temperature may be arbitrarily set, but the range of 10 to 15 ?? is appropriate.

The heating part 90 is provided inside the basic rail 10 and is a part which generates or stops heat by the drive signal of the driving part 80.

3 is a flowchart illustrating a process of performing the track branch snow melting method according to the present invention.

Referring to FIG. 3, first, the first temperature sensor 60 measures the ambient temperature around the track (S300).

When the measured atmospheric temperature is equal to or less than the first preset temperature, the snowfall detecting sensor 40 detects snow near the track branch (S310). As described above, if the ambient temperature is less than the first set temperature, and the eye is present between the metal plate of the snow detection sensor 40, the capacitance of the charger is changed by the change of the dielectric constant and the current is changed accordingly Presence is detected.

When the eyes are detected, the second temperature sensor 50 detects a line temperature around the tongle 20 (S320).

When the reference temperature setting unit 70 receives a detection signal from the first temperature sensor 60 and the second temperature sensor 50, the reference temperature setting unit 70 compares both detection signals to extract a lower temperature from the atmospheric temperature and the line temperature, and then uses the reference temperature. Set to (S330).

The driving unit 80 operates the heating unit 90 when the calculated reference temperature is equal to or less than a second preset temperature (for example, 5 ??) (S340). The heating unit 90 generates heat based on the driving signal of the driving unit 80 to heat the line, and as the line is heated, snow around the line melts.

The driving unit 80 stops the operation of the heating unit 90 when the line temperature rises above the third preset temperature by the heat generated by the heating unit 90 (S350). If the temperature of the track is above a certain temperature (for example 15 °), all snow around the track is in a molten state, and at this time, the driving unit 80 stops the operation of the heating unit 90.

Although the present embodiment is illustrated and described with reference to the track branch snow melting device, the present invention is not limited thereto, but it can be widely applied to various snow melting devices.

According to the present invention, it is possible to provide a track branch snow melting apparatus and method capable of preventing the risk of branching of a train in advance by removing snow present in the track branch.

In addition, it is possible to prevent the waste of power by driving the heating unit only when the temperature is below a certain level using the temperature sensor.

In addition, there is an effect that can remove the snow more reliably by driving the heating unit using two temperature sensors.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
