Railroad rails are a very important element in guiding train operation. In particular, as the high-speed train traveling at a speed of more than 300 km travels on rails, the importance becomes more important.

Therefore, precise manufacturing and construction of railway rails is important, but defect inspection is required for rapid maintenance.

Conventionally, a large number of workers visually inspected whether there are scratches or damaged parts on the exterior of a rail, but there is a problem in that rapid inspection is difficult and work efficiency is lowered.

In addition, it is not preferable because the operator has to take the risk of safety accident as the operator manually inspects the long rail.

Accordingly, Korean Patent Application No. 10-2007-0112606, as shown in Figure 1 drive means for moving the main body 1, a rotary jig (2) formed to rotate the rail (R), a rotary jig Disclosed is a rail inspection device for railroad which includes a means for turning the rail (2) to rotate and move forward and backward so that the rail can be selectively flipped during visual inspection of the rail.

However, the disclosed patent is a device for moving and rotating the rail required for visual inspection, and there is a problem in that durability inspection of the rail itself is not possible because the configuration for inspecting the crack of the rail is not provided.

Accordingly, the Republic of Korea Patent No. 10-1321790, as shown in Fig. 2 to detect the radiation that passes through the radiation emitted from the radiation generating device 122 through the railway rail 30 to detect the defects present in the railway rail A flaw detection vehicle is disclosed.

In other words, since the flaw is detected while traveling at a relatively slow speed, the convenience is lowered, and it is not preferable because it hinders the running of other trains.

In addition, while the rail is moved along the rail, the rails may be separated from each other by way of a branch. However, when the flaw detection is performed in the same manner with respect to the branch, there is a problem in that the gap is mistaken as a defect.

In addition, the detection of the rail is in contact with the rail due to the characteristics of the rail flaw detection equipment, but it is not preferable because the detection equipment causes damage due to the separation distance of the tapping machine.

In addition, the rail may have various separation distances, and for precise detection, the rail must move in close contact with the rail, but such a configuration is not disclosed in the prior art, and thus high precision is difficult to expect.

In addition, there is a problem that the utilization is low so that the defect can be detected only for the rail.

An object of the present invention is to solve the problems of the prior art as described above, and detects the proximity of the turner in the track inspection car that can detect the internal defects of the rails and the defects on the concrete while simultaneously moving the rails at high speed.

As shown in the drawing, the rail flaw detection unit 220 has a flaw detection part 222 for irradiating ultrasonic waves, flaw detection part 222, an installation part 224 on which the flaw detection part 222 is installed, and a predetermined height below the vehicle body 100. It is fixed to have a support portion 226 for supporting the load of the flaw detection portion 222, and a sensor lift 230 for adjusting the height of the mounting portion 224 when the length is selectively changed from one side of the support portion 226 It is configured to include.

The flaw detector 222 is positioned above the rail R and configured to irradiate ultrasonic waves downward. In addition, the support part 226 is fixed to maintain a predetermined height in the lower direction with respect to the vehicle body 100 to firmly support the load of the installation part 224 and the flaw detection part 222.

The installation part 224 is supported by a load 226, and can be lifted in the up / down direction by the sensor elevator 230. That is, the installation part 224 is supported in a state where a plurality of flaw detection part 222 is suspended in the lower side, and is disposed parallel to the support part 226. In addition, the mounting portion 224 is supported by the load in a state rotatable to the support portion 226 by the sensor elevator 230.

Therefore, when the installation unit 224 is raised by the operation of the sensor elevator 230, the flaw detection unit 222 is far from the rail (R), the impact on obstacles, etc. mounted on the upper surface of the rail (R) Will be avoided.

Both sides of the expansion and contraction of the cylinder 232, the cylinder 232 and the mounting portion 224, and rotates with respect to one side of the support portion 226 at the time of expansion and contraction of the cylinder 232 to the mounting portion It is configured to include a force transmission unit 234 to elevate (224).

The cylinder 232 is configured to provide a force to the force transmission unit 234 at the time of expansion and contraction so that the support unit 226 can be elevated, and is disposed long in the longitudinal direction of the vehicle body 100.

Therefore, when lifting or lowering the flaw detection unit 222 can operate without a shock load. That is, when the cylinder 232 is disposed in the up / down direction, the cylinder 232 receives a large load due to vibration generated while the track inspection vehicle is traveling, and in this case, the cylinder 232 may be easily damaged by the fatigue load.

In order to prevent such a problem from occurring, the cylinder 232 is disposed long to the left / right, but the force can be transmitted to the installation part 224 through the force transmission part 234, and the force transmission part 234 By configuring the central portion of the ash to rotate with respect to the support 226, the flaw 222 is lifted when the length is stretched, and the flaw 222 is lowered when the length is reduced.

On the other hand, the track inspection vehicle is provided with a wheel width adjustment unit 500 so that the interval between the wheels H in parallel rolling motion spaced apart from each other can be adjusted.

Hereinafter, a detailed configuration of the wheel width adjusting unit 500 will be described with reference to FIGS. 9 and 10.

FIG. 11 is a schematic diagram showing a control method of a branch detection device for a track inspection vehicle according to the present invention, and FIG. 12 is a flowchart showing a control method of a branch detection device for a track inspection vehicle according to the present invention.

As shown in the drawing, a plurality of control systems are installed at the lower part of the front and rear of the vehicle body 100, and the branch sensor detecting the branch device 300 which detects the branch when the vehicle body 100 moves continuously detects whether the branch is approaching. Signal discrimination step (S200) and the signal discrimination step of determining whether the detection signal detected by any one of the step (S100), the multi-branch detection device 300 is a branch-related signal (S200) and the signal discrimination step When the tap-off is detected at S200, a flaw detection device raising step (S300) for raising the flaw detector 200 installed below the vehicle body 100, and the other one of the plurality of tap-changer detecting devices 300 detects the tap-off.

 The signal discriminating step (S200) is a process of determining a branching-related detection signal among various detection signals detected by the branching detecting device 300, and determines whether the signal is a branching unit based on a detection time at which the signal is detected.

When it is determined that the detection time of the signal detected by the branch sensor 300 in the signal discriminating step S200 is a branching machine by satisfying the set time, the flaw detector raising step S300 is performed.

The flaw detection device rising step (S300) is a step of raising the flaw detection unit 222 disposed on the same rail (R) with the turn-off detection device 300 that detects the turn-off so that the impact with the turn-off device can be avoided. .

Then, when the rear tapper detecting device 300 located on the same rail (R) detects the tap-off, after a predetermined time has elapsed, the flaw detector 200 is lowered to its original state to detect the rail (R). Make it possible.
