Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a trolley-type track detection apparatus having a hydraulic track guide unit, and a trolley-

The present invention relates to a trolley type track detection apparatus, and more particularly, to a trolley type track detection apparatus that includes a hydraulic track guide unit that is hydraulically driven and includes a hydraulic track guide unit capable of measuring a track error while preventing departure of the track The present invention relates to a trolley type orbital detecting apparatus and a method thereof.

In general, the track serves not only to guide the train to a predetermined path, but also to protect the lower structure by relieving the load of the train transmitted to the lower portion. In addition, the stability and riding comfort of trains are directly affected by track performance, and most of railway noise and vibration are caused by the interaction of track and wheel. Thus, the orbit can directly affect the stability, economy and comfort of the entire railway system.

 However, such a trajectory is caused by a slight permanent deformation due to the passage of the train, and such deformation accumulates as time passes, which causes a fault in the running road surface. Particularly, since the orbit is composed of a simple structure compared with an excessive train load acting upon high-speed traveling, it is necessary to carry out the special maintenance It is a structure.

 In the maintenance of the track fault which occupies a large part of the maintenance work of the track, the orbit inspection car is already put into practical use, and the state of the track is regularly checked and the maintenance is put on the basis of the predetermined evaluation criterion. This is in some sense a conservative system that is close to state surveillance conservation, but with respect to priorities and input of conservation inputs, the lack of data support and the mobilization of conservative efforts to mobilize the remaining labor resources, It is a situation that is distributed sequentially according to experience and intuition.

 In the railway, the role of the track is to surely realize the roadway defined by the track geometry, but in reality, there is an error. In other words, the orbit supports the train and smoothly induces the train. However, when the train is subjected to repetitive load, the trajectory is deformed, causing inconsistency in the running surface of the track. This is called track irregularity do.

 This kind of track misalignment is likely to lead to a major accident due to a small track misalignment due to the speeding up of the tracked vehicle. If the track error increases, the train fluctuates more and the passenger's ride becomes worse. If this kind of track error becomes large, or if there is a misalignment of the other track, a misalignment of the train may occur. Therefore, the inspection of the track fault is a very important factor in securing the stability of the railway transportation, and the need for maintenance and repair of the railway is gradually increasing.

Such a track fault is an indicator of track maintenance and a crucial factor in the stability of train driving and passenger comfort. The maintenance of the track should be able to ensure the ride comfort by ensuring the prevention of the accident from the viewpoint of safety as a work for restoring the fault of the track within a certain standard limit.

 These trajectory errors are measured dynamically using a trajectory detector at regular intervals according to the operation of the train, and may be measured statically using a manpower or a simple measuring device if necessary.

On the other hand, the track should be constructed and managed within a certain tolerance in order to ensure the running safety and ride comfort of railway vehicles. These errors are called trajectory errors, such as misalignment, misalignment, horizontal misalignment, warping, and gait. Among these detection methods, there are two main methods of detecting high and low misalignment and misalignment. First, there is a method of measuring the relative distance from a string of a certain distance, that is, a method of measuring by a Versine method. The present method is a method of measuring the displacement at three positions mainly from the vehicle body of a vehicle and obtaining the longitudinal displacement. The second method is to measure the absolute position in space using a gyroscope and an accelerometer, and calculate the trajectory error based on the absolute position.

1 is a view showing a trolley type track fault detector according to the prior art.

1, the trolley type track fault detector 30 according to the related art is provided with a high level sensor 31, a plane strain sensor 32, a gauge sensor 33 and a level sensor 34 In this case, because the sensor is installed only on the left or right rail, it is not possible to measure the difference between the left rail and the right rail at the same time.

Accordingly, in the case of the trolley type track fault detector 30 according to the related art, only one rail of each of the right and left rails is measured, and the other rail is measured again. In other words, the trolley type track detector for measuring the height difference and the direction error of one rail has a problem in that it is necessary to move the main measurement string twice to measure the difference between the left and right rails.

On the other hand, as a prior art, Korean Patent No. 10-737517 discloses an invention entitled " Railway Rail Measurement System and Measurement Method ", which will be described with reference to FIGS. 2A and 2B.

The arithmetic unit calculates the interval between the rails according to the shrinkage and expansion ratio of the rail according to the temperature according to the output signal of the sensor unit, calculates the height difference between the two side rails to calculate the gauge of the side rails, And outputs the operation result of the operation unit.

In other words, the railway rail measurement system according to the prior art measures the height and spacing between the two side rails while moving along the railway rail, and calculates the height of the railway rail, , The flatness of the upper surface of the rail, and horizontal misalignment can be measured, but it can be said to be a contact type measuring method in which the rail is contacted with the rail.

However, in the railway rail measurement system according to the related art, as described above, in order to measure the height difference between the left and right rails and the directional misalignment, as shown in FIGS. 2A and 2B, There is a problem that the measurement time is lengthened and the accuracy is deteriorated accordingly.
