Description

  The present invention relates to a rail correction method and a rail correction system for a branched rail portion where a branching device is provided or a portion where a guard rail is laid when the rail is corrected by a rail correction vehicle.

  In order to operate the train normally at the railway company, regular rail correction work is performed, thereby removing the wavy wear on the rail surface and reducing noise and vibration. Therefore, rail correction work is performed using the rail correction car at night after the train operation ends and before the operation start. Rail correction work measures the cross-sectional shape of the parietal surface for each fixed section, determines the optimal shape of the parietal surface after correction based on the measured shape, and uses a rail with a rail rectifier to obtain the shape of the parietal surface. A cutting pattern (cutting pressure / cutting angle and number of passes by a cutting grindstone) is determined, and based on this, rail cutting is performed by a rail cutting wheel.

  Rail cutting is performed at a constant speed of about 5km / h, and when the switch for starting cutting is pushed from the driver's seat of the rail cutting car, the rotating grinding wheel descends and comes into contact with the rail. Be started. When the cutting end switch is pressed after the cutting section has been cut forward, the rotating grinding wheel rises and the first (one pass) cutting is completed. Next, when the switch for starting cutting is pushed while retreating at a constant speed of about 5 km / h, the rotating grinding wheel descends and comes into contact with the rail, cutting starts and the cutting section ends. When the cutting end switch is pressed, the rotating grinding wheel rises, and the second (two pass) cutting is completed. By repeating such operations, the rail is corrected to the target optimal top surface shape.

  On the other hand, on railway tracks, there are sections where branch rails, railroad crossings, or guard rails for preventing derailment are installed, and in such a section, when a target rail is trimmed, the grinding wheel is replaced by another rail. The target rail cannot be corrected by touching, or the target rail can be corrected, but the branch, rail crossing, or part of the guard rail that cannot be corrected properly is also corrected and damaged. There was a problem to say. In such a section, it is necessary to stop the correction by the rail correction car and to perform the correction manually by using a small cutting machine or the like, which is inefficient.

  In Patent Document 1, a grinding unit including a guide wheel with a flange and a grinding wheel is provided in a manner that can slide in the width direction of the vehicle body, so that the section where the guardrail is installed can be ground with a rail grinding wheel. In addition, an invention is proposed that proposes to provide a pressing mechanism between the grinding unit and the vehicle body to cause the grinding unit to follow each rail so that the flange of the guide wheel always contacts the inner surface of the rail. Has been. In this technical field, the terms “grinding” and “cutting” are the same.

  However, in Patent Document 1, although the accuracy in which the center in the descending direction of the grinding wheel is not shifted from the center of the rail is ensured and the grinding wheel does not rectify the guard rail, the grinding wheel is tilted and advanced. It is difficult to cope with the work of correcting or not correcting the branch portion of the rail having a branch portion such as a crossing rail.

  Also, in recent rail grinding cars, a plurality of parallel grinding wheels are provided, and each grinding wheel is lowered to approximately the same position of the rail in synchronization with the traveling speed so as to perform rail grinding. It has become. The driver of the rail rectification car starts the rail rectification by pressing the rectification start switch so as not to rectify the branch part of the rail that has the divergence part like the crossing rail. When finishing the cut, the driver's seat and the grinding wheel are separated from each other, so it is not possible to confirm the site, and the cut start switch is pushed slowly to start the rail cut, and the cut end switch is fast. Press to finish rail correction. Therefore, there are many uncorrected parts, and it is necessary to perform manual correction on these parts using a small reducing machine or the like, which is inefficient.

Japanese Patent Laid-Open No. 9-88001

  The object of the present invention is to provide a high-precision cutting with a rail-cutting vehicle, where there is no residual cutting as much as possible, in a section where a branching, crossing or guard rail is installed, which has been difficult to cut with a conventional rail-cutting vehicle. It is proposed to do.

  In order to solve the above-described problems, in the rail grinding method of the present invention, in rail grinding by a rail grinding vehicle, a control device that controls at least the descent and rise of the grinding wheel, and the control device is used for rail grinding. A switching device that can be selected to be controllable from the inside or the outside of the vehicle and a remote device that can control at least the lowering and raising of the grinding wheel from the outside. The switching device controls the control device of the rail grinding vehicle. When controllable from the outside is selected and a signal for lowering the grinding wheel is input to the remote device, the grinding wheel of the rail grinding wheel is lowered and rail grinding is started. When a signal for raising the straight grinding wheel is input, the grinding grinding wheel of the rail grinding wheel rises and rail grinding is stopped.

  According to the present invention, the rail grinding wheel is provided with a control device that controls at least the lowering and raising of the grinding wheel, and a switching device that can select the control device from inside or outside the rail grinding wheel. And a remote device that can control at least the descent and ascent of the grinding wheel from the outside. With the switching device, select the control device to be controllable from the outside of the rail grinding wheel, and input the signal for lowering the grinding wheel to the remote device at a position where the start point and end point of the grinding section can be recognized accurately Then, the grinding wheel of the rail grinding wheel descends and rail grinding starts, and when the rising signal of the grinding wheel is input to the remote device, the grinding wheel of the rail grinding wheel rises and the rail grinding is stopped. Therefore, it is possible to finely adjust the desired cutting section at the site, prevent accidents that cause damage by correcting the portion that cannot be properly corrected, The part can be reduced.

  Preferably, in the remote device, the grinding wheel of the rail grinding wheel is lowered and rail grinding is performed only while the input of the signal for lowering the grinding wheel is continued, and the input of the signal is performed. When cut off, the grinding wheel rises and rail cutting is stopped.

  According to such a configuration, the operator of the remote device performs the rail correction only while pressing the input button for lowering the grinding wheel, and if the hand is released from the input button, the rail correction is stopped. In addition, since it is not necessary to press the up button, and the chances of erroneous button press and failure to press are reduced, the operator can finely correct the desired correction section at ease on site.

  Also, the present invention is characterized in that the remote device exchanges signals with the control device by wireless communication.

  According to such a configuration, the remote device is characterized in that it transmits and receives signals to and from the control device that controls at least the lowering and raising of the grinding wheel of the rail grinding wheel by wireless communication. The person can control the lowering and raising of the grinding wheel with a remote device without being troubled by a cable or the like, so that the desired grinding section can be finely tuned with more peace of mind.

  In the rail grinding system according to the present invention, the rail grinding machine can be selected so that at least the control device for controlling the descent and raising of the grinding wheel and the control device can be controlled from inside or outside the rail grinding wheel. A remote device capable of transmitting / receiving signals to / from the control device by wireless communication from outside and controlling at least the lowering and raising of the grinding wheel, and the switching device controls the rail cutting. When the control wheel is selected to be controllable from the outside of the main wheel and a signal for lowering the cutting wheel is input to the remote device, the cutting wheel of the rail cutting wheel is lowered and rail cutting is started. When a signal for raising the grinding wheel is input to the apparatus, the grinding wheel of the rail grinding wheel rises and the rail grinding is stopped.

  This rail grinding system includes at least a control device that controls the descent and raising of the grinding wheel and a switching device that can select the control device from inside or outside the rail grinding wheel. The remote control device is configured by a remote device capable of transmitting and receiving signals to and from the control device by wireless communication from the outside and controlling at least the lowering and raising of the grinding wheel. When the control device is selected so that the control device can be controlled from the outside of the rail grinding wheel, and the signal for lowering the grinding wheel is input to the remote device, the grinding wheel of the rail grinding wheel is lowered and the rail grinding is performed. This is a system in which when the signal for raising the grinding wheel is input to the remote device, the grinding wheel of the rail grinding vehicle rises and the rail grinding is stopped. Because it is possible to control the descent and ascent of the grinding wheel of the main vehicle, the on-site worker can finely perform the rail trimming in the desired trimming section and reduce the remaining portion of the grinding it can.

  According to the present invention, an operator can remotely control a rail correction in a section where a branch rail, a railroad crossing, or a guard rail for preventing derailment is installed, which has been difficult to correct or has a lot of uncut portions. Rail cutting can be performed by controlling the descent and raising of the car grinding wheel, preventing accidents that would damage parts that could not be properly grounded. The remaining part can be reduced.

  Hereinafter, embodiments of the present invention will be described.

  FIG. 1 is a conceptual diagram of a branching device targeted by the present invention. FIG. 1A shows a branching device at point 12, and the hatched portion with hatching is a portion that cannot be corrected properly. FIG. 1B shows a branching device of the crossing 14, and the hatched portion of the hatching is a portion that cannot be properly corrected. In addition, although the guard rail 16 is often installed in the section where the branching device of the crossing 14 is provided to facilitate branching, it is difficult to properly correct the rail 10 in this portion. When such a section is in the middle of correction, rail correction is stopped as close as possible to the hatched portion of the hatched line or the guard rail 16, and rail correction is started as soon as possible after the hatched portion of the hatched line or the guard rail 16 is completed. This is efficient because there are few uncorrected parts. For this purpose, the driver of the rail grinding wheel 1 whose position of lowering and raising of the grinding wheel 24 of the grinding device unit 2 cannot be seen is pressed by pressing the switch for finishing the grinding to stop the rail grinding. Rather than entrusting the operation of starting rail cutting by pressing the switch, the operator can hold the remote device 7 so that the operator can see the lowering and rising positions of the cutting wheel 24 of the cutting device unit 2 and press the switch for finishing cutting to move the rail. It is wise to stop the correction and leave the operation to start the rail correction by pressing the start switch.

  Also, when cutting between the turnouts, after passing the hatched portion of the hatched line or the guard rail 16, start the rail correction as soon as possible, and perform the rail cut as soon as possible before the hatched portion of the next hatched line or the guard rail 16. It is necessary to cancel the operation, so that the operator who can see the position of the lowering and raising of the grinding wheel 24 of the grinding device unit 2 holds the remote device 7 and presses the grinding start switch to start the rail grinding. It is efficient to push the stop switch to leave the operation of canceling rail correction because there are few uncorrected portions.

  FIG. 2 is a view showing a rail grinding wheel according to an embodiment of the present invention. The rail grinding wheel 1 includes a grinding device unit 2 between the carts. Moreover, the control apparatus 4 which controls the fall and raising of the grinding wheel 24 of the grinding machine unit 2 at least is provided. The control device 4 may include control of a rail correction pattern. In the present embodiment, the switching device 3 capable of selecting the control device 4 so as to be controllable from the inside or the outside of the rail grinding vehicle 1 is provided in the front driver's seat 5, but may be provided in the rear driver's seat 6. The control device 4 may be provided. In both driver seats, switching between forward and reverse is convenient. When driving the rail grinding car 1 in the forward direction, the driver operates at the front driver seat 5, and when driving the rail grinding car 1 in the backward direction, the driver operates at the rear driver seat 6. Manipulate.

  The correction device unit 2 is shown in FIG. The correction device unit 2 is provided with a total of four guide wheel frames 20 of two on each side and a total of ten correction devices 28 of five on each side. Each guide wheel frame 20 supports two small guide wheels 22, and prevents lateral shift or curve shift to the rail 10 of the correction device unit 2 to improve rail correction accuracy. It is improving. The correction device 28 is arranged as a target with respect to the rail width direction and the traveling direction so that there is no difference in rail correction between forward and backward. Further, the correction device unit 2 can separately control the five correction devices 28 on each side, and can correct both sides of the rail 10 simultaneously or only one side of the rail 10. is there.

FIG. 4 shows the relationship between the grinding device 28 and the rail 10, and each grinding device 28 includes a grinding wheel 24, a grinding wheel motor 26 for rotating the grinding wheel 24, and an upper and lower cylinder (not shown). When the rail cutting start signal is input to the control device 4, the control device 4 lowers the cutting wheel 24 to the upper and lower cylinders, applies a predetermined pressure, and starts cutting while rotating the rail 10, When a rail cutting end signal is input to the control device 4, the control device 4 raises the cutting grindstone 24 to the upper and lower cylinders and ends the cutting.

  By an actuator not shown, the grinding wheel 24 is moved from the horizontal direction at an angle α between the rails 10 (gauge side) to an angle of 75 degrees from the horizontal direction and at an angle β between the rails 10 (field side) from the horizontal direction at 45 degrees. The tilt angle is also selected so as to obtain an optimal top surface shape after grinding according to the measured cross-sectional shape of the rail head surface. The tilt angle range on the gauge side of the rail is larger than that on the field side because the rail side of the rail is in contact with the flange of the train wheel and wear is larger than that on the field side. The tilt angle can be increased.

  FIG. 5 is a conceptual diagram of the rail grinding vehicle 1 and the remote device 7 according to an embodiment of the present invention. The remote device 7 is provided with a wireless transmitter / receiver, and when the switching device 3 of the rail grinding vehicle 1 is switched so that the control device 4 can be controlled from the outside of the rail grinding vehicle 1, switching is performed. Signals can be transmitted / received to / from a wireless transceiver built in the apparatus 3. As a communication method, a method used in a wireless LAN may be used. The remote device 7 is provided with an input means such as a button for inputting at least a lowering signal input and a rising signal input of the grinding wheel 24, and the remote device 7 receives a lowering signal of the cutting wheel 24. When input, the wireless transceiver built in the switching device 3 receives the signal and transmits the signal to the control device 4. The control device 4 that has received the signal transmission lowers the grinding wheel 24 of the rail grinding wheel 1 through the upper and lower cylinders and starts rail grinding. Similarly, when a signal for raising the grinding wheel 24 is input to the remote device 7, a wireless transceiver built in the switching device 3 receives the signal and transmits the signal to the control device 4. Upon receiving the signal transmission, the control device 4 raises the grinding wheel 24 of the rail grinding wheel 1 through the upper and lower cylinders, and the rail grinding is stopped.

  If only one side of the rail 10 is to be corrected, the remote device 7 may be provided with a selection means for a mode in which both sides of the rail 10 are corrected simultaneously and a mode in which only one side of the rail 10 is corrected, The switching device 3 may be provided with selection means for a mode in which both sides of the rail 10 are corrected simultaneously and a mode in which only one side of the rail 10 is corrected.

  When the remote device 7 is used, a worker who can see the lowering and raising positions of the grinding wheel 24 of the grinding device unit 2 at the site has the remote device 7 and starts cutting at a desired position. Is pushed to lower the grinding wheel 24 to start rail grinding, and a grinding end switch is pushed to raise the grinding wheel 24 to stop rail grinding. Thereby, the driver of the rail grinding wheel 1 in which the position of the lowering and raising of the grinding wheel 24 of the grinding device unit 2 is not visible operates the rail more finely than operating the cutting start switch and the cutting end switch. It is possible to perform the correction, and it is possible to prevent an accident that the portion that cannot be properly corrected is corrected and damaged, and the remaining portion of the correction can be reduced.

  As another embodiment of the remote device 7, two input means for inputting the lowering signal and the rising signal of the grinding wheel 24 of the remote device 7 can be combined into one. While the remote device 7 continues to input the lowering signal of the grinding wheel 24, the wireless transmitter / receiver built in the switching device 3 receives the signal and transmits the signal to the control device 4. . Upon receiving the signal transmission, the control device 4 lowers the grinding wheel 24 of the rail grinding wheel 1 through the upper and lower cylinders and maintains the state. When the input of the signal for lowering the grinding wheel 24 from the remote device 7 is interrupted, the wireless transceiver incorporated in the switching device 3 receives the signal OFF and transmits the signal OFF to the control device 4. Upon receiving the signal OFF transmission, the control device 4 raises the grinding wheel 24 of the rail grinding wheel 1 through the upper and lower cylinders, and the rail grinding is stopped. In this case, even if the wireless state is poor, rail correction is stopped by an OFF signal, so that the input of the lowering signal of the grinding wheel 24 is accepted by two input means, but the raising of the grinding wheel 24 is increased. The input of the signal is safer than the case where the wireless state is bad and it is not accepted.

  Note that the radio signal from the remote device 7 is transmitted to the control device 4 via the radio transceiver built in the switching device 3, but the radio signal from the remote device 7 is directly transmitted to the radio of the control device. A mode of transmission to a transceiver is also possible. However, in this case, if the switching device 3 is not selected so as to be controllable from the outside, it is necessary not to accept a radio signal from the remote device 7. Moreover, although the wired system connected with a cable etc. can also be considered as the remote device 7, a wireless system is preferable in consideration of the handling of the remote device 7 in the field.

  FIG. 6 shows a comparison of the correction range of the branching device at point 12 according to the conventional example and the present invention. The hatched portion of the hatched line is a portion that cannot be corrected properly, and the hatched portion of the mesh is in a range that can be corrected. In the conventional example of FIG. 6A, the cutting was stopped about 20 m before the rail 10 on the side where the point 12 is closed. However, in the present invention example of FIG. 6B, the point 12 is closed. Since the cutting can be performed up to about 2 m before the rail 10 on the side of the rail, the remaining portion of the cutting is reduced, and the cutting can be performed up to the hatched portion of the oblique line.

  FIG. 7 shows a comparison of the correction range of the branching device of the crossing 14 according to the conventional example and the present invention. The hatched portion of the hatched line is a portion that cannot be corrected properly, and the hatched portion of the mesh is in a range that can be corrected. Further, the correction of the rail 10 in the portion where the guard rail 16 is installed is stopped. In the conventional example of FIG. 7 (a), the cutting was stopped approximately 20m on both sides across the crossing 14 or the guard rail 16, but in the present invention example of FIG. 7 (b), the crossing 14 or the guard rail 16 is Since the cutting can be performed up to about 2 m on both sides, the rail can be finely adjusted, and the remaining portion of the correction can be reduced.
