Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a track-and-rail line alignment device for transferring a track-and-rail vehicle capable of traveling on both a railway track and a road from the road side to the track side, and a track-and-rail vehicle equipped with the device.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, a land-rail vehicle has been used when inspecting and repairing an on-track train line. This railroad vehicle is a vehicle that travels on a normal road to a railroad crossing near the work place, and when it reaches the relevant railroad crossing, it is transferred to a track and then moved to the work site on the track using track wheels.

When the railroad vehicle arrives at the railroad crossing, the track and the railroad vehicle are in an intersecting state. Therefore, when placing a railroad crossing on a railroad crossing, first lower the rolling stock at the bottom of the railroad car and press the ground with the rolling stock to raise the railroad car by the reaction force and use it for land running. Float the tires. Then, after rotating the railroad car itself along the track, the entire railroad car was lowered so that the track wheels would land on the track.

[0004]

[Problems to be solved by the device]

 However, before floating the railroad car on the turntable, it was necessary to accurately position the position of the railroad car or the position of the turntable at the center position of the intersecting track. If it is not placed correctly, even if the railroad vehicle is rotated and its direction becomes parallel to the track direction, the position of the track wheels will shift and the track wheels cannot be lowered on the track. This initial alignment was performed by an operator other than the driver of the railroad vehicle, notifying the driver while observing the positional relationship between the railroad vehicle and the track. During this work, it was difficult to quickly stop at the correct position due to the difficulty of communication due to engine noise, etc. Traffic at the level crossing is usually heavy, and it has been desired that the line placement work be completed quickly and accurately with a minimum of redoing.

The inventor of the present invention has studied a device in which a light irradiation device such as an LED is provided at the center of the bottom of a turntable. This device irradiates visible light vertically downward from the center of the rolling trolley to form a light mark on the railroad crossing and move the railroad vehicle. By this movement, when the light mark is located at the reference position of the gauge previously arranged at the railroad crossing, the position of the railroad vehicle is set as the mounting position.

However, even if this device is a little more accurate, there is no difference in observing it with the human eye, and the communication problem between the observer and the driver remains the same. , The point that the observer needed separately from the driver was the same.

[0007]

[Means for Solving the Problems]

 The invention according to claim 1 is provided in a railroad vehicle in which the bottom of the railroad vehicle itself is provided, and the bottom of the railroad vehicle is lowered to float the railroad vehicle itself so that the direction of the railroad vehicle itself can be changed to the track direction. A track-rail vehicle track alignment device, which includes a ground mark detection sensor provided on the bottom surface of the above-mentioned rolling stock, and a ground-mark detection sensor provided at or near the driver's seat of the track vehicle, which detects a predetermined ground mark. Then, there is provided an informing means for issuing a signal recognizable to the driver, and a track-and-rail line alignment device characterized by the following:

In the first aspect, the ground mark detection sensor may be provided at a rotation center of the turntable. Further, the ground mark detection sensor includes a light beam irradiation unit and a light receiving unit, and when the light receiving unit detects the light reflected from the ground mark by the light beam irradiated from the light beam irradiation unit, the notifying unit sends a signal. Good. Further, the light beam irradiation unit may irradiate infrared rays.

Further, the notifying means may be a buzzer. Further, a visible light irradiation device capable of irradiating visible light toward the ground may be provided near the ground mark detection sensor. The invention according to claim 7 is a railroad vehicle equipped with these railroad on-vehicle line alignment devices.

[0010]

[Action]

 In the track-and-vehicle on-vehicle line alignment apparatus according to the first aspect, when the ground mark detection sensor detects a mark, the notification means issues a signal to the driver. This eliminates the need for an observer and allows the machine to accurately detect the position and immediately contact the driver without losing timing.

If the ground mark detection sensor is provided at the center of rotation of the turntable, accurate alignment can be performed regardless of the rotational position of the railroad car or the turntable. Further, the above ground mark detection sensor includes a light beam irradiation unit and a light receiving unit, and when the light receiving unit detects the light reflected from the ground mark by the light beam irradiated from the light beam irradiation unit, the notification means emits a signal. Since it is detected by light, more accurate detection is possible. In particular, if the light beam irradiating unit irradiates infrared rays, accuracy is maintained because other light beams are less likely to be disturbed.

Further, when the above-mentioned notifying means is a buzzer, the eyes of the driver can be concentrated to the outside for driving, which is a safer work. Furthermore, if a visual light irradiation device is provided in the vicinity of the above-mentioned ground mark detection sensor, it becomes a guide for the arrangement of the ground marks and can be arranged efficiently.

A railroad vehicle equipped with these railroad on-vehicle line alignment devices also has the above-described operation.

[0014]

【Example】

 An embodiment of the track-and-vehicle line alignment device of the present invention will be described with reference to FIGS. The block diagram is shown in FIG. The railroad on-vehicle line alignment device 1 mainly includes an optical sensor 3 and a buzzer 5. The optical sensor 3 is arranged on the turntable 7, and the buzzer 5 is arranged on the driver's seat 9.

The optical sensor 3 has an infrared lamp, a light receiving element, and an internal switch (not shown) inside, and the infrared lamp emits infrared rays to the outside. When the infrared ray emitted from the infrared lamp has a sufficient intensity to be reflected, the light receiving element captures the infrared ray and turns on the internal switch. When the internal switch is turned on, a current flows through the buzzer 5 and the buzzer 5 sounds. Therefore, when the turntable 7 moves to a predetermined position, and the infrared rays emitted from the infrared lamp and further reflected are captured by the light receiving element, the buzzer 5 in the driver's seat 9 sounds and the turntable 7 is given to the driver. Tell them that you are in place.

As shown in FIG. 5, the turntable 7 is attached to the bottom surface of the railroad vehicle 11 substantially at the center thereof. The shaft 7a of the rolling trolley 7 can be expanded and contracted downward from the bottom surface of the railroad vehicle 11 by an operation lever (not shown) near the rolling trolley 7. When the shaft 7a is fully extended and the bottom surface of the rolling bed 7 is pressed against the ground, the railroad vehicle 11 is lifted and the four land-driving tires 11a, 11a, 11b, 11b can be lifted. Further, the shaft 7a does not rotate with respect to the main body of the railroad vehicle 11, but the cover 19 described later is rotatable with respect to the shaft 7a. Therefore, the tracked vehicle 11 can be freely rotated by the force of a person while the tracked vehicle 11 is lifted. Of course, the shaft 7a itself may be rotatable with respect to the main body of the railroad vehicle 11.

Here, the term “rotatable” does not mean that all 360 ° is rotatable, but also includes the case where only a certain range, for example, 300 ° or 180 ° is possible. However, the turntable 7 that can rotate 360 degrees with respect to the main body of the railroad vehicle 11 is preferable because it is not necessary to set the turntable 7 in a predetermined position in advance.

As shown in FIG. 2, the optical sensor 3 is fixed together with the LED light emitter 13 provided auxiliary to a hole portion in the center of the inside of the support plate 17 via a support 15 made of hard vinyl chloride. Has been done. Further, as shown in FIG. 3, the support plate 17 is provided with columns 17a and 17b connected to the shaft 7a at both inner ends thereof, and is attached to the bottom surface of the turntable 7 through the columns 17a and 17b. There is. Therefore, even if the railroad car 11 is lifted up, the bottom of the turntable 7 is pressed against the ground, and the columns 17a and 17b receive the load, so that the optical sensor 3 and the LED light emitter 13 are not destroyed. A cover 19 as a grounding member is attached below the supporting plate 17 via a bearing or the like (not shown). Since the cover 19 is rotatable with respect to the support plate 17, the cover 19 is also rotatable with respect to the main body of the railroad vehicle 11. Since the optical sensor 3 and the LED light emitter 13 are fixed to the support plate 17, the rotational position is also fixed to the main body of the railroad vehicle 11. Although the cover 19 exists below the support plate 17, the optical sensor 3 and the LED light emitter 13 can send and receive light to and from the ground through a hole 19a provided in the cover 19.

Here, it is also possible to adopt a structure in which the turntable 7 to which the optical sensor 3 and the LED light emitter 13 are attached rotates with respect to the main body of the railroad vehicle 11. Even if the optical sensor 3 and the LED light emitter 13 are rotated with respect to the main body of the railroad vehicle 11 as described above, the optical sensor 3 and the LED light emitter 13 are located at the central portion of the turntable 7, that is, the rotation center C. Therefore, the positions of the optical sensor 3 and the LED light emitter 13 with respect to the railroad vehicle 11 do not change.

Next, as shown in FIG. 6, the gauge 21 as a ground mark is a rectangular combination of plate materials. A plate member for fixing the shape is provided on the diagonal line. When one side 21b of the gauge 21 is brought into contact with the inside of the line L, the opposite side 21a is located at the center of the two lines L, L, that is, the track center LC. A light reflection tape 23 is attached to the surface of the side 21a of the track center LC. For example, the light reflecting tape 23 has a length of 450 mm and a width of 10 mm.

A procedure for actually mounting the railroad vehicle 11 using these configurations will be described. First, the driver sets the gauge 21 as shown in FIG. Next, after the power switch of the railroad on-vehicle line alignment device 1 is turned on and activated, the railroad vehicle 11 is entered into the railroad crossing S and slowly passes over the gauge 21. As shown in FIGS. 4 and 5, when the central portion of the turntable 7 reaches the position of the light reflecting tape 23, the infrared rays emitted from the infrared lamp of the optical sensor 3 are reflected with sufficient intensity. The light receiving element captures the infrared rays and turns on the internal switch. When the internal switch is turned on, a current flows through the buzzer 5 and the buzzer 5 sounds. The driver stops the railroad vehicle 11 by the ringing of the buzzer 5. At this time, the central portion C of the turntable 7 is at the track center LC. Of course, if the buzzer 5 stops after going too far, the railroad vehicle 11 may be moved back and the buzzer 5 may be turned on again. Next, the power switch of the railroad on-vehicle line alignment device 1 is turned off to stop the buzzer 5 from ringing.

Next, after getting off from the driver's seat 9, the hydraulic lever is operated to extend the shaft 7 a of the turntable 7 to push the turntable 7 to the ground, and the reaction force lifts the railroad vehicle 11. Thereafter, the driver manually rotates the railroad vehicle 11 in the arrow direction shown in FIGS. Since the bearing is provided between the support plate 17 and the cover 19 of the turntable 7, it can be easily rotated by one person. When the direction of the railroad vehicle 11 becomes the direction of the track, the rotation is stopped. Next, after the track wheels F1, F2, F3 and F4 are arranged at the corners of the railroad vehicle 11, the hydraulic lever is operated to retract the shaft 7a of the rolling table 7. Since the center of rotation C of the turntable 7 is accurately located at the center LC of the track, if the track vehicle 11 is parallel to the track, the track vehicle 11 itself will naturally be correctly positioned on the track. Thus, the track wheels F1, F2, F3, F4 are quickly and accurately placed on the track L without redoing. Further, the landing tires 11a, 11a, 11b, 11b also come into contact with the ground between the lines L, L, or at least the drive wheels 11b, 11b come into contact with each other. You can drive. After moving the railroad vehicle 11 to the work place in this way, as shown in FIG. 7, the lifting platform 25 of the loading platform can be raised to inspect and repair the trolley line D and the like.

In this embodiment, it is very easy to mechanically position the rotation center C of the turntable 7 on the track center LC without any human observation, so that it can be quickly performed without manpower. The wiring work is completed accurately. Therefore, it will not adversely affect traffic. The LED light emitter 13 is provided almost adjacent to the optical sensor 3. This is a guideline when the railroad vehicle 11 is first put in the railroad crossing S, and then the gauge 21 is inserted under the railroad vehicle 11 and arranged in contact with the inside of the line L. That is, since the irradiation position of the LED light emitting device 13 substantially corresponds to the position directly below where the optical sensor 3 passes, the position of the gauge 21 is determined from the direction of the railroad vehicle 11 and the current irradiation position of the LED light emitting device 13. If it is arranged, it will be a guideline for the optical sensor 3 to pass over it. Therefore, the work for arranging the gage 21 becomes efficient, and it is less likely to interfere with level crossing traffic. In addition to this effect, when the light sensor 3 fails due to the presence of the LED light emitter 13, the irradiation position of visible light emitted by the LED light emitter 13 is checked by human observation, and the position of the railroad vehicle 11 is checked. Matching can be done.

In the above embodiment, the light sensor 3 uses infrared rays, but other wavelength light, for example, visible rays or ultraviolet rays may be used. Although the buzzer 5 is used as the notifying means, the buzzer 5 may be used instead of the buzzer 5 to output a voice from a speaker, a notification lamp may be provided to notify by light, or both sound and light may be used for notification. Alternatively, the position may be notified by changing the position of an indicating member such as a needle like a meter.

Further, although the gauge 21 is arranged in the track especially before mounting, if the mark is formed at the track center LC of the railroad crossing with a material having a higher reflectance than the periphery, the gauge 21 is especially arranged. No need. Further, the columns 17a and 17b may also serve as the shaft 7a. In this case, the columns 17a and 17b expand and contract due to hydraulic pressure.

In the above embodiment, the optical sensor 3 corresponds to the ground mark detecting sensor, the buzzer 5 corresponds to the notification means, the infrared lamp corresponds to the light beam irradiating section, the light receiving element corresponds to the light receiving section, and the LED emits light. The device 13 corresponds to the light irradiation device for visual recognition, and the light reflection tape 23 corresponds to the ground mark.

[0027]

[Effect of device]

 According to the track-rail on-vehicle line alignment device of claim 1, the ground mark detection sensor automatically detects the ground mark and the notification means notifies the driver with a recognizable signal. Can perform wiring work accurately and quickly.

If the ground mark detection sensor is provided at the center of rotation of the turntable, it is possible to mount the turntable accurately without being set in advance, which is more efficient. Further, the above ground mark detection sensor includes a light beam irradiation unit and a light receiving unit, and when the light receiving unit detects the light reflected from the ground mark by the light beam irradiated from the light beam irradiation unit, the notification means emits a signal. Since the ground mark is detected by light, more accurate detection is possible. In particular, if the light beam irradiating unit irradiates infrared rays, accuracy is maintained because it is less likely to be disturbed by other light beams.

Further, when the above-mentioned notifying means is a buzzer, the eyes of the driver can be concentrated outside for driving, which is a safer work. Furthermore, if a visual light irradiation device is provided in the vicinity of the above-mentioned ground mark detection sensor, the ground mark can be efficiently arranged as a guide for the arrangement when it is arranged, and it is unlikely to cause obstacles to level crossing traffic.

A railroad vehicle equipped with these railroad on-vehicle line alignment devices also has the above-mentioned effects.
