Description

Rim rail level meter {LIM RAIL LEVEL MEASURING DEVICE}

The present invention relates to a rim rail level meter, and more particularly, to measure the height of the upper surface of the rim rail installed between the rail and the rail based on the height of the upper surface of the rail installed on both sides of the track, and displaying the measured data numerically. At the same time, it relates to a rim rail level meter that alerts you when you are out of the measurement range.

In an electric railway, when the traveling speed is faster than 300 km / h, a phenomenon occurs that the wheels of the electric vehicle revolve without being in close contact with the rails provided on both sides of the track. This is because the power of the rotary electric motor is transmitted to the wheels of the electric vehicle, and the electric vehicle is advanced through friction of the wheels and rails of the electric vehicle.

Therefore, in the case of a high-speed driving of 500 km / h, which is desired in an electric railway, it is necessary to take a method of directly propelling the electric vehicle without using the wheels of the electric vehicle in order to eliminate anxiety.

As an alternative to solve this problem, a linear motor has been proposed, and since the linear motor can move on a straight line, directly power, and have high acceleration and deceleration, it is not only used for high-speed railway but also for automating the sorting of wagons in a yard. It is used, and its use is gradually expanding.

The linear motor is classified into a synchronous type and an asynchronous type. The synchronous linear motor places a magnetic pole fixed on one of the mover side and the stator side, and sends alternating power to the other side, and an electromagnetic force acts therebetween.

Here, in order to apply the driving force in one direction, the polarity of the magnetic pole should always be detected, and the direction of the current should be changed corresponding to the polarity, and the speed can be controlled by continuously changing the frequency so as to be synchronized with the speed.

As shown in Fig. 1, the asynchronous linear motor has a plate (secondary side) of a thick copper or aluminum conductor on either the mover side or the stator side, and the other side is grooved in, for example, a plate-shaped iron core. It is constructed by digging a hole into which a three-phase winding is put (primary side).

Here, when three-phase alternating current flows to the primary side, a moving magnetic field is generated, and thus an induced current flows to the secondary side and an electromagnetic force acts therebetween. Therefore, the moving direction of the moving magnetic field is caused by three-phase alternating current flowing to the primary side. This is determined, and the driving force in one direction can be obtained. In addition, although speed control may change a voltage to a fixed frequency, it changes and uses a frequency in order to improve the efficiency of an electric motor.

On the other hand, as shown in (c) of FIG. 1, the asynchronous linear motor is provided with a mover provided with an iron core and a winding generating a moving magnetic field is installed in the lower part of the electric vehicle, and a stator (for example, a rim rail such as an aluminum plate) Is installed at the center of the rails on both sides of the track.

In addition, between the mover and the stator (hereinafter referred to as rim rail) to form a gap of approximately 10mm intervals, it should be installed so that the mover and the stator do not directly contact, it should be maintained continuously. This occurs when the height of the gap is higher or lower than approximately 10mm, the driving force efficiency of the mover is lowered according to the height difference of the gap.

Therefore, it is necessary to determine the initial installation state of the rim rail, or to maintain the installed rim rail, the situation is required to accurately measure the height of the air gap, high efficiency measuring equipment.

Therefore, the present invention was created to solve the above problems, for example, while conveying in contact with the rail provided on both sides of the track, while measuring the height of the upper surface of the rim rail to display the measured data numerically and at the same time Its purpose is to provide a rim rail level meter that warns through lamps and buzzers when it is out of the measurement range compared to the height of the upper surface of both rails.
