Description

  The present invention relates to a railroad vehicle, and more particularly to a technique for determining a stop position of a railroad vehicle.

  The track-and-rail vehicle has wheels for traveling on a road and iron wheels for traveling on a track. In general, when traveling on a track, the vehicle travels on a road until a railroad crossing, and the position of the iron wheel is adjusted to the track within the railroad crossing. Here, when the track-and-rail vehicle enters the railroad crossing, the iron wheel and the track are in an intersecting state, and thus the track-and-ground vehicle needs to be horizontally turned by the turntable. In this case, if the center of the turntable of the track-and-rail vehicle is not at the center in the width direction of the track, the iron wheel cannot be placed on the track because the iron wheel is not arranged above each rail even if the turntable is rotated. Therefore, it is necessary for the track-and-rail vehicle to accurately determine the stop position so that the turning center of the turntable becomes the center in the width direction of the track in the railroad crossing.

  Therefore, Patent Document 1 is a track-and-rail vehicle provided with a turntable at the bottom of the railroad vehicle, provided on the ground mark detection sensor provided on the bottom surface of the turntable and the driver's seat of the track-and-rail vehicle or the vicinity thereof, There is disclosed a device provided with notifying means for generating a signal recognizable to the driver when the ground mark detection sensor detects a predetermined ground mark. Certainly, according to such a track-and-rail vehicle, when the ground mark is arranged at an accurate position, it is considered that the stop position is accurately determined.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. In addition, the same code | symbol is attached | subjected about the same or equivalent component, and the description is abbreviate | omitted when description overlaps. In addition, the present invention is widely applicable to a track-and-rail vehicle including at least a wheel for traveling on a road and an iron wheel for traveling on a track in a vehicle body and a turntable that can turn horizontally on the vehicle body, Here, an example will be described in which the present invention is applied to a track-and-rail vehicle having an aerial work device provided on a vehicle body.

Example 1
As shown in FIG. 1, the track-and-rail vehicle 1 has a front wheel 11F and a rear wheel 11R as wheels for traveling on a road in a chassis frame 10 of the vehicle body 3, and above the front wheel 11F, A cab 5 for performing a traveling operation is provided. A subframe 20 is fixed to the upper portion of the chassis frame 10 and extends in the front-rear direction with substantially the same width as the chassis frame 10. A track T (rails R 1, R1) laid between predetermined rails is provided on the front and rear sides of the subframe 20. A front-side track traveling device 23F and a rear-side track traveling device 23R that support the iron wheels 21F and 21R for traveling on R2) are provided. Further, the iron wheels 21F and 21R can be moved between a position (traveling position) projecting downward by the front side track traveling device 23F and the rear side track traveling device 23R and a stored position (the illustrated example is stored). Show the position). In this specification, “gauge” means the shortest distance from the center in the width direction of the rail R1 to the center in the width direction of the rail R2.

  On the upper part of the sub-frame 20, there is provided a swivel base 25 that can be swung by a swivel motor (not shown), and a boom 26 is pivotally supported on the swivel base 25 so as to be raised and lowered. A hoisting cylinder 27 is connected between the boom 26 and the swivel base 25, and the boom 26 is hoisted by extending and retracting the hoisting cylinder 27. In addition, the boom 26 is configured in a multi-stage manner so that it can be expanded and contracted by expanding and contracting an expansion / contraction cylinder (not shown) provided therein, and the work table 28 always maintains horizontal at the tip thereof. It is attached so that it can swing freely. In addition, outrigger devices 29F and 29R are provided in front of and behind the subframe 20 to jack up the tracked vehicle 1 by projecting in the vehicle width direction during work.

  As shown in FIGS. 2A and 2B showing the frame structure of the track-and-rail vehicle 1, the subframe 20 can be horizontally turned with the vehicle body 3 lifted by protruding below the vehicle body 3 and touching the ground. The turntable 30 is fixed. As shown in FIG. 3, the turntable 30 includes two expansion devices 31 </ b> L and 31 </ b> R (collectively referred to as “expansion device 31”) that can be expanded and contracted by a hydraulic cylinder (not shown), and the expansion device 31. The upper ends of the telescopic devices 31L and 31R are respectively fixed to the left and right portions in the traveling direction of the subframe 20. The turntable 33 includes an upper rotary plate 35 to which the lower end of the telescopic device 31 is fixed and a lower rotary plate 37 in contact with the ground, and these are relatively between the upper rotary plate 35 and the lower rotary plate 37. A rotating device 36 for rotating is provided. The rotation device 36 is rotation-controlled by an operation device (not shown), for example. The lower rotating plate 37 has a substantially rectangular shape in plan view, and is formed such that the length of the long side is longer than the gauge and the length of the short side is shorter than the gauge.

  By providing such a configuration, first, when the telescopic device 31 of the turntable 30 is extended, the lower rotary plate 37 of the turntable 33 is in contact with the ground, and further, the extension operation is continued. 1 is lifted off the ground. At this time, the rail vehicle 1 is supported only by the turntable 30. And in this state, when the turntable 33 rotates, the rail vehicle 1 turns horizontally with the center of the turntable 33 as the rotation center C. The rotation center C is located at the approximate center of gravity of the rail vehicle 1 and is the center with respect to the width direction of the subframe 20.

  In the first embodiment, as shown in FIG. 2, the first irradiation means 41, the second irradiation means 42, the third irradiation means 43, and the fourth irradiation means 44 (which emit light for reference) ( When referred to generically, “irradiation means 40” is provided for the subframe 20. These irradiation means 40 irradiate light vertically downward, for example, a laser pointer is used.

  The first and third irradiating means 41 and 43 are on the right side of the subframe 20, and the second and fourth irradiating means 42 and 44 are on the left side of the subframe 20 with approximately the same spacing in the front-rear direction. Is provided. And the 1st and 2nd irradiation means 41 and 42 are provided in the position of the substantially half distance between gauges from the rotation center C of the turntable 30 toward the front side of the sub-frame 20, and the 3rd and 3rd The four irradiation means 43 and 44 are provided at a position approximately half the distance between the gauges from the rotation center C of the turntable 30 toward the rear side of the subframe 20. Further, since the rotation center C of the turntable 30 is on the center line Lc in the width direction of the subframe 20, the first and third irradiation means 41, 43 and the second and fourth irradiation means 42, 44 are different from each other. Thus, they are arranged at substantially equal distances in the left-right direction with respect to the center line Lc extending in the longitudinal direction of the vehicle body through the rotation center C of the turntable 30. The line connecting the first irradiation means 41 and the second irradiation means 42 and the line connecting the third irradiation means and the fourth irradiation means are orthogonal to the center line Lc, and It is parallel.

  By arranging the irradiation means 40 as described above, when the rotation center C of the turntable 30 is located at the center between the rail R1 and the rail R2, the first and second irradiation means 41 and 42 are used for the rail vehicle. The rail R1 on the one traveling direction side is irradiated, and the rail R2 on the opposite side in the traveling direction of the rail vehicle 1 is irradiated by the third and fourth irradiation means 43 and 44. Therefore, the driver can easily stop the rail car 1 at the stop position by recognizing that the irradiation is performed in this way.

In addition, when the track-and-rail vehicle 1 is approaching at a substantially right angle with respect to the track T, at least one irradiation unit of the irradiation unit 40 is a target rail (if the first and second irradiation units are used). If it can be recognized that the rail R1, the third and fourth irradiation means are irradiating the rail R2), then all the irradiation means 40 inevitably irradiate the target rail. It can be recognized that this is a stop position. Further, even if it is not known whether or not the vehicle has entered at right angles to the track T, the rails targeted by the first and second irradiation means 41 and 42 or the third and fourth irradiation means 43 and 44 are used. In the case of irradiation, it has entered substantially perpendicular to the trajectory T, and it can be recognized that it is an appropriate stop position. Further, when the vehicle does not enter the track T at a substantially right angle, for example, one of the irradiation positions of the first and fourth irradiation means 41 and 44 is positioned forward of the vehicle body 3 with respect to the rail R1. If the other irradiation position is shifted to the rear side of the vehicle body 3 with respect to the rail R2 and the shifted distance is substantially equal, an appropriate stop position (a position where the turning center and the center between the gauges coincide) It can be recognized that.

  Note that the method of recognizing the irradiation position by the driver may be, for example, a method in which another worker confirms the irradiation position outside the vehicle and transmits it to the driver, but in this embodiment, the imaging means and the display means are used. It has become easier to recognize.

  As shown in FIGS. 2A and 2B, a camera 51 as an imaging unit is provided in the subframe 20 so as to face downward, and all irradiation positions by the irradiation unit 40 are set. It is set to be included in the shooting range. The video by the camera 51 is transmitted by wire or wirelessly to a monitor 55 as a display means installed in the cab 5 where the driver's seat is located, and can be viewed from the driver's seat. Note that the video on the monitor 55 is transmitted in real time (real time) from the video taken by the camera 51.

  In the embodiment, by including the camera 51 that can capture the irradiation position by the irradiation unit 40 and the monitor 55 that displays the image captured by the camera 51 in real time, the driver himself can determine the irradiation position. Since the rail vehicle 1 can be moved while confirming the positional relationship between the rails R1 and R2, and the irradiation position gradually approaches the rails R1 and R2, the stop operation can be performed efficiently. It becomes possible. Further, it is not necessary to perform complicated work such as checking the irradiation position by an operator other than the driver squatting to the side of the vehicle body or entering the lower part of the vehicle body.

(Example 2)
In the first embodiment, the first to fourth irradiation units are arranged on both side surfaces of the subframe. However, the present invention is not limited to this. The first to fourth irradiation means may be arranged at a predetermined interval, for example, at a position other than both side surfaces of the subframe, or at a predetermined position on a chassis frame or a turntable other than the subframe. It does not matter. Hereinafter, as another embodiment of the present invention, FIG. 4 shows an example in which the irradiation means 40 is provided on a turntable. Note that parts that are the same as or correspond to those in the first embodiment are denoted by the same reference numerals as in FIGS.

  As shown in FIG. 4, the first to fourth irradiation means 41 to 44 in the second embodiment are provided at the four corners of the lower rotating plate 37 in the turntable 30. In a state where the long side 37L of the lower rotating plate 37 coincides with the width direction of the vehicle body 3 (the state of FIG. 4A, hereinafter referred to as “standard position”), the first irradiating means 41 of the lower rotating plate 37 At the corner on the left front side in the traveling direction, the second irradiation means 42 is at the corner on the left rear side in the traveling direction of the lower rotating plate 37, and the third irradiation means 43 is on the right front side in the traveling direction of the lower rotating plate 37. The fourth irradiation means 44 are provided at the corners on the right rear side in the traveling direction of the lower rotating plate 37, respectively. The 1st and 2nd irradiation means 41 and 42 and the 3rd and 4th irradiation means 43 and 44 are provided in the position where the distance of the left-right direction from the centerline Lc of the vehicle body 3 becomes a half of a gauge. Therefore, the distance between the first irradiation means 41 and the third irradiation means 43 and the distance between the second irradiation means 42 and the fourth irradiation means 44 are substantially the same as the gauge.

  In the second embodiment in which the irradiation means 40 is arranged as described above, as shown in FIG. 4A, when the stop position is aligned, the rolling base 30 is first in the standard position, and the railcar 1 Enters the railroad crossing. Then, by rotating the turntable 30 90 degrees clockwise in plan view, the short side 37S of the lower rotating plate 37 is in a state of being coincident with the width direction of the vehicle body 3 as shown in FIG. . As a result, the first and second irradiation means 41 and 42 are located at a position approximately half the distance between the gauges from the rotation center C of the turntable 30 toward the front side of the vehicle body 3. 43 and 44 move from the rotation center C of the turntable 30 toward the rear side of the vehicle body 3 to a position that is approximately half the distance between the gauges. The first and third irradiating means 41 and 43 and the second and fourth irradiating means 42 and 44 are left and right with respect to a center line Lc extending in the longitudinal direction of the vehicle body through the rotation center C of the turntable 30. The positions are approximately equidistant in the direction. Further, the line connecting the first irradiation unit 41 and the second irradiation unit 42 and the line connecting the third irradiation unit and the fourth irradiation unit are orthogonal to the center line Lc.

  Thus, when the irradiation means 40 moves as described above by the rotation of the turntable 30, the rotation center C of the turntable 30 is located at the center of the rail R1 and the rail R2 as in the first embodiment. The rail R1 on the traveling direction side of the rail vehicle 1 is irradiated by the first and second irradiation means 41 and 42, and the rail on the opposite side of the traveling direction of the rail vehicle 1 is irradiated by the third and fourth irradiation means 43 and 44. R2 will be irradiated. Therefore, the driver can easily stop the rail car 1 at the stop position by recognizing that the irradiation is performed in this way.

  In the second embodiment, as shown in FIG. 4C, when the rail vehicle 1 enters at an angle that is not substantially perpendicular to the track T, the turntable 30 is adjusted to the angle of the track T with respect to the approach direction. Are rotated so that the short direction of the lower rotating plate 37 and the longitudinal direction of the track T (the longitudinal direction of the lower rotating plate 37 and the width direction of the track T) coincide with each other. You can create a state to get. And the driver | operator can stop the track-and-rail vehicle 1 to a stop position easily by moving the track-and-ground vehicle 1 back and forth in this state.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention. Is included in the present invention. For example, the laser pointer is exemplified as the irradiation means, but the present invention is not limited to this, and any means may be used as long as the irradiated point can be recognized when the ground is irradiated at least from the height of the subframe.

  Moreover, although the example provided with the 1st thru | or 4th irradiation means was shown, it is not restricted to this. For example, if any one of the first to fourth irradiating means is provided, if the irradiating means irradiates the target rail when it enters at a substantially right angle with respect to the track, an appropriate stop is achieved. It can be recognized that it is a position. In addition, for example, when only the first and second irradiation means are arranged, the first and second irradiation means enter the rail at a right angle by irradiating the rail at the same time, It can be recognized that the stop position is appropriate. Also, for example, when only the first and third irradiation means are arranged, the first and third irradiation means enter the rail at a right angle by irradiating the rail at the same time, It can be recognized that the stop position is appropriate. Further, only the first, second and third irradiation means may be arranged. In this case, the first and second irradiation means and the first and third irradiation means are provided. Compared to the case, the stop position can be recognized with higher accuracy.

  In addition, the example in which the monitor as the display unit is disposed in the cab has been described. However, the present invention is not limited thereto, and the monitor may be provided, for example, on the side wall of the vehicle. In this case, other workers will check the monitor, but it is not necessary to go under the vehicle, and the irradiation position can be easily checked. Here, when the monitor is arranged outside the cab, other workers do not necessarily check the monitor, and for example, the driver can check the monitor through a window or a mirror. In addition, when the image | video from a camera is transmitted to a monitor by radio | wireless, it is good also as a portable monitor.

  In addition, although an example is shown in which an image captured by a camera is displayed as it is on a monitor, the present invention is not limited to this. For example, display that emphasizes the rail and the irradiation position can be performed by performing image processing on the video imaged by the camera. In addition, it is possible to provide notification means for performing guidance such as “50 cm to the stop position”. By providing such a notification means, the driver or the like does not need to watch the monitor, and the guideline to the appropriate stop position is specifically recognized as the distance between the irradiation position and the trajectory. It becomes possible to perform the stop work efficiently. In addition, the guidance by the notifying means first performs a rail image extraction process for recognizing and extracting a rail portion from the captured video by performing image processing on the captured video in real time, and an irradiation position. An irradiation position extraction process for recognizing and extracting this is performed. A known technique can be used for the image processing. For example, the rail extraction processing recognizes two parallel lines having a predetermined interval (width of one rail) extracted as an edge. Is. Further, the irradiation position extraction process is, for example, extracting a color corresponding to the laser wavelength of a laser pointer used for the irradiation unit, or predetermining a predetermined position in the imaging range by the camera as the irradiation position. is there. And, for example, by comparing the extracted rail with the irradiation position on the basis of the predetermined value corresponding to the pixel or information between the preset gauges, the rail and the irradiation position in the traveling direction of the vehicle The distance is calculated, and the calculated distance is guided. In addition, guidance is a method that is performed by voice, a method that is displayed on a monitor, or a method that combines these methods. The guided distance may be divided by a predetermined size such as 50 cm, 40 cm, 30 cm, etc., and a distance such as “it is a little more” is qualitatively determined. It may be a representation.

  Further, although the example in which the irradiation means is fixed to the sub-frame or the lower rotating plate has been shown, it may be provided so as to be movable. For example, there are wide gauges, narrow gauges, etc. in addition to the standard gauges, but it is possible to cope with different gauges by configuring the gauges so that they can be fixed at predetermined mounting positions in accordance with these gauges. In the case of the subframe, a plurality of attachment portions may be provided at positions where the distance in the front-rear direction is changed. In the case of the lower rotary plate, a plurality of attachment portions may be provided in the long side portion.
