Description

  The present invention relates to an obstruction device that is supported by a body frame of a leading vehicle of a gauge variable vehicle.

  A leading vehicle of a rail vehicle that travels in a snowy area is provided with an obstruction device that can eliminate snow on the track. For example, an obstacle device disclosed in Patent Document 1 includes an obstacle rubber that eliminates pebbles and the like on a rail, and a snow plow having a V-shape in plan view and an arc-shaped cross section that eliminates snow accumulation on a track.

  In addition, a variable-gauge vehicle is known that can continuously run in a standard gauge section and a narrow gauge section by changing the wheel interval with a change in the gauge size. When the variable-gauge vehicle disclosed in Patent Document 2 passes between the gauge converters installed on both sides of the track in the gauge conversion section installed between the standard gauge section and the narrow gauge section, the gauge conversion device and The wheels are slid in the vehicle width direction due to mechanical interaction with the variable gauge carriage, and the wheel interval is automatically changed.

Japanese Patent No. 4762054 Japanese Patent Laying-Open No. 2006-164035

  However, when the obstacle device of Patent Document 1 is applied to a gauge variable vehicle, the end portion of the snow plow in the vehicle width direction interferes with the gauge conversion device. On the other hand, if the size of the snow plow in the vehicle width direction is shortened to prevent interference with the gauge conversion device, the snow removal function of the snow plow is reduced. Further, although the vehicle limit is set to a low level immediately above the rail, the vehicle limit is set to a relatively high level at a location shifted from the rail in the vehicle width direction. Of the auxiliary obstacles for removing pebbles and the like on the rails, the installation of flexible obstacle rubber is allowed under the domestic regulations, even if it exceeds the vehicle limit and is within the building limit. However, if the rubber barrier is installed on the basis of the standard gauge section, there is a possibility of exceeding the construction limit of the narrow gauge section.

  In addition, when the specifications of the running section used by the snow plow and the exhaust rubber are different (for example, the exhaust rubber is used only in the standard gauge section and the snow plow is used in both the standard gauge section and the narrow gauge section) However, it is difficult to prevent both the interference with the gauge change device and the transcendence of the building limit that changes between the standard gauge section and the narrow gauge section without impairing the snow removal function of the snow plow.

  Therefore, the present invention provides an obstacle device for a variable-gauge vehicle capable of simultaneously maintaining the snow removal function of a snow plow, preventing interference with a gauge conversion device, and preventing interference with the construction limit of an elastic obstacle. Objective.

  According to an aspect of the present invention, there is provided an obstacle device for a variable-gauge vehicle that includes a vehicle body base of a leading vehicle of a variable-gauge vehicle that directly passes through the gauge conversion device from a first track section to a second track section having different gauge dimensions. An obstacle device supported by a frame, a snow plow having a convex shape toward the front, and an elastic obstacle that protrudes below the snow plow toward the rail upper surface of the first track section, A snow plow main body part that overlaps the elastic obstacle and a position in the vehicle width direction, and an end snow plow part that is disposed adjacent to the outside in the vehicle width direction of the snow plow main body part. The drive device lifts and lowers the elastic obstacle and the end snow plow part independently of each other.

  According to the above configuration, since the end snow plow portion can be raised when the variable-gauge vehicle passes the gauge conversion device, the snow plow can change the gauge while the snow plow is sufficiently long in the vehicle width direction. Interference with the apparatus can be prevented. Also, when traveling on the second track section, by raising the elastic obstacle with the end snow plow lowered, the elastic obstacle is kept within the building limits while maintaining the function of the snow plow. Can fit. Therefore, it is possible to simultaneously maintain the snow removal function of the snow plow, prevent the snow plow from interfering with the gauge change device, and prevent the elastic exhaust body from interfering with the construction limit.

  FIG. 1 is a side view of an obstacle device 10 of a variable gauge vehicle 1 according to the embodiment. 2 is a plan view of the obstruction device 10 shown in FIG. As shown in FIGS. 1 and 2, the gauge variable vehicle 1 includes a standard gauge section (first track section) and a narrow gauge section (second track section) having a smaller gauge size than the standard gauge section in a snowy area. It is a vehicle that travels directly. When the variable-gauge vehicle 1 passes between the gauge conversion devices, which are ground facilities installed on both sides of the track, in the gauge conversion zone between the standard gauge section and the narrow gauge section, Due to the mechanical interaction between them, the wheel slides in the vehicle width direction, and the wheel interval is automatically changed. The gauge conversion device and the gauge variable carriage are known ones (see, for example, JP-A-2006-164035).

  At the lower part of the front end portion of the vehicle body frame 2a of the leading vehicle 2 of the leading variable vehicle 1 is mounted an obstacle device 10 for removing obstacles such as foreign matter on the track and snow accumulation.

The snow guide surface (front surface) of the snow plow 11 is curved in a convex arc shape toward the rear in a side view. The snow plow 11 is divided into a snow plow body portion 17 and an end snow plow portion 18. The snow plow main body 17 is disposed at the center in the vehicle width direction with respect to the track, and has a convex shape toward the front. The end snow plow part 18 is disposed adjacent to the outside of the snow plow main body part 17 in the vehicle width direction. The snow plow body portion 17 is further divided into a central snow plow portion 19 and an intermediate snow plow portion 20. The central snow plow portion 19 is disposed at the center in the vehicle width direction with respect to the track, and has a V-shape that protrudes forward. The intermediate snow plow portion 20 is disposed adjacent to the outer side in the vehicle width direction of the central snow plow portion 19.

  The elastic obstacle 12 is a plate-like body made of an elastic material (for example, rubber). The elastic obstacle 12 overlaps with the intermediate snow plow portion 20 of the snow plow main body portion 17 in the vehicle width direction, and protrudes below the snow plow 11 toward the rail upper surface of the standard gauge. The elastic obstacle 12 is disposed along the snow plow 11 and is inclined to the rear as it goes outward in the vehicle width direction. The elastic obstacle 12 is locally disposed so as to be located immediately above the rail of the standard gauge section, and excludes small foreign matters such as pebbles on the rail of the standard gauge to the side.

  The drive device 13 is disposed behind the snow plow 11. The drive device 13 includes a first actuator for the elastic obstacle 12 and a second actuator for the end snow plow portion 18. In the present embodiment, the first actuator and the second actuator are the first fluid pressure cylinder 13A and the second fluid pressure cylinder 13B, respectively. The frame 14 is disposed behind the snow plow 11. The frame 14 supports a snow plow 11, an elastic obstacle 12, and a driving device 13. The impact absorber 15 absorbs the impact by crushing when the impact transmitted from the obstacle to the snow plow 11 is excessive. The shock absorber 15 is sandwiched between the frame 14 and the support member 16. The support member 16 is fixed to the lower part of the front end portion of the vehicle body frame 2a.

FIG. 4 is a longitudinal sectional view at a position including the elastic obstruction body 12 of the obstruction device 10 shown in FIG. 2, and is a longitudinal sectional view perpendicular to the main surface of the snow plow. As shown in FIGS. 3 and 4, the intermediate snow plow portion 20 is a plate member having a circular arc shape that protrudes rearward in a side view, and the front surface thereof is a snow guide surface 20a. A connecting portion 20 c that is fixed to the frame 14 with a bolt B <b> 1 protrudes from the back surface 20 b of the intermediate snow plow portion 20. A notch 20d cut upward from the lower end is formed in the lower portion of the intermediate snow plow portion 20. The notch 20d is formed at a position biased outward in the vehicle width direction in the intermediate snow plow portion 20, and is opened toward the end snow plow portion 18 side.

  The elastic obstacle 12 is disposed with a gap from the intermediate snow plow portion 20, and is exposed from the notch 20d when viewed from the front. The elastic obstacle 12 includes a first elastic plate 21 and a second elastic plate 22 superimposed on the first elastic plate 21. The 1st elastic board 21 has the tongue piece part 21a which protruded below rather than the 2nd elastic board 22 toward the rail upper surface. The elastic obstacle 12 in the lowered state is inclined so as to go forward as it goes to the lower end. The upper part of the elastic obstacle 12 is held by a holding member 23. The holding member 23 is fixed to a rotating shaft 24 disposed behind the elastic obstacle 12.

  The rotating shaft 24 is rotatably supported by bearing bases 25A and 25B provided on the frame 14. The rotary shaft 24 is connected to the rod 13Aa of the first fluid pressure cylinder 13A. The first fluid pressure cylinder 13A is arranged such that the rod 13Aa extends in the vertical direction. The elastic obstacle 12 is raised by rotating around the rotation shaft 24 as a fulcrum in conjunction with the downward movement of the rod 13Aa of the first fluid pressure cylinder 13A.

  The holding member 23 is attached to the bracket 26 connected to the rotating shaft 24, the back member 27 connected to the bracket 26 and abutting on the back of the upper part of the elastic obstacle 12, and the front of the upper part of the elastic obstacle 12. And a front member 28 that abuts. The elastic obstacle 12 is held by the back member 27 and the front member 28 by inserting the bolt B2 through the back member 27, the elastic obstacle 12 and the front member 28 and fastening them together. In the present embodiment, the front member 28 of the holding member 23 is a facing portion that faces the upper edge 20e of the notch 20d from the rear. In the present embodiment, in the lowered state of the elastic obstacle 12 (FIG. 3), the lower portion of the holding member 23 is exposed at the notch 20d when viewed from the front.

  The front surface 28a of the front member 28 includes an intermediate point 28aa having the same height as the upper edge 20e of the notch 20d and a lower end point 28ab in the lowered state of the elastic obstacle 12 (FIG. 4). A region R between the intermediate point 28aa and the lower end point 28ab of the front surface 28a of the front member 28 has a shape along the rotational trajectory of the elastic obstacle 12 as viewed from the side. For example, the region R has a curved shape that protrudes forward. The thickness of the front member 28 as viewed from the side gradually decreases from the intermediate point 28aa, which is the protruding portion, toward the lower end point 28ab. The front surface 28a of the front member 28 further includes an upper end point 28ac that is above the intermediate point 28aa. The thickness of the front member 28 as viewed from the side gradually decreases from the intermediate point 28aa toward the upper end point 28ac.

  Due to the shape as described above, in the lowered state of the elastic obstacle 12 (FIG. 4), the gap between the upper edge 20e of the notch 20d and the intermediate point 28aa of the front member 28 is small, and the snow plow 11 is It is difficult for snow to drain into this gap. Further, also in the raised state of the elastic obstacle 12 (FIG. 7), the gap between the upper edge 20e of the notch 20d and the lower end point 28ab of the front member 28 is small, and the snow removed by the snow plow 11 is this gap. It is hard to get into.

  A first stopper that restricts the lifting range of the elastic obstacle 12 by interfering with the elastic obstacle 12 or the holding member 23 is fixed to the frame 14. Specifically, the first stopper includes an upper stopper 29A arranged above the elastic obstacle 12 and the holding member 23, and a lower stopper 29B arranged below the elastic obstacle 12 and the holding member 23. Have. The upper stopper 29A has a stopper surface 29Aa that comes into contact with the upper end of the elastic obstacle 12 in the raised state of the elastic obstacle 12 (FIG. 7). The lower stopper 29B has a stopper surface 29Ba that comes into contact with the lower surface of the bracket 26 in the lowered state (FIG. 4) of the elastic obstacle 12. The stopper surface 29Aa of the upper stopper 29A and the stopper surface 29Ba of the lower stopper 29B are provided with shim plates (not shown) for height adjustment in the raised state and the lowered state, respectively, to adjust the thickness of the shim plate. Thus, the ascending state and the descending state can be adjusted to an appropriate height.

  A first heater is attached to the first stopper. Specifically, the first heater has an upper heater 30A attached to the upper stopper 29A and a lower heater 30B attached to the lower stopper 29B. The upper heater 30A is attached to a surface of the upper stopper 29A that is different from the stopper surface 29Aa. The lower heater 30B is also attached to a surface of the lower stopper 29B that is different from the stopper surface 29Ba.

  FIG. 5 is a longitudinal sectional view at a position including the end snow plow portion 18 of the obstruction apparatus 10 shown in FIG. As shown in FIGS. 3 and 5, the end snow plow portion 18 is a plate member having an arc shape that is recessed rearward in a side view, and a front surface thereof is a snow guide surface 18 a. The end surface 18b of the end snow plow portion 18 facing the notch 20d side (that is, the end surface 18b at the same height as the notch 20d of the end surfaces on the inner side in the vehicle width direction of the end snow plow portion 18) It is inclined to go outward in the width direction. That is, of the sides defining the notch 20d of the snow plow 11, the sides on the outer side in the vehicle width direction are inclined so as to go outward in the vehicle width direction as going downward. The end face 18 b of the end snow plow part 18 is formed at an obtuse angle with respect to the snow guide surface 18 a of the end snow plow part 18. That is, the end surface 18b is inclined so as to go outward in the vehicle width direction as it goes forward.

  On the back surface 18c of the end snow plow portion 18, an arm 31 projects rearward. The arm 31 includes a first arm portion 31a protruding from the back surface 18c, and a second arm portion 31b fixed to the first arm portion 31a with a bolt B3. The second arm portion 31b is fixed to a rotary shaft 32 disposed behind the end snow plow portion 18, and the rotary shaft 32 is rotatably supported by bearing bases 25B and 25C provided on the frame 14. Yes. That is, the bearing bases 25A to 25C are three in total, and the central bearing base 25B supports both the rotary shaft 24 for the intermediate snow plow portion 20 and the rotary shaft 32 for the end snow plow portion 18. ing.

  The rotation shaft 32 is connected to the rod 13Ba of the second fluid pressure cylinder 13B. The second fluid pressure cylinder 13B is arranged such that the rod 13Ba extends in the vertical direction. The stroke amount of the rod 13Ba of the second fluid pressure cylinder 13B is larger than the stroke amount of the rod 13Aa of the first fluid pressure cylinder 13A. The end snow plow portion 18 moves upward by rotating about the rotating shaft 32 in conjunction with the downward movement of the rod 13Ba of the second fluid pressure cylinder 13B.

  The frame 14 is fixed with a second stopper 33 that regulates the range of lifting of the end snow plow portion 18. As the arm 31 comes into contact with the second stopper 33, the lifting range of the end snow plow portion 18 is restricted. The second stopper 33 includes a stopper surface 33a that interferes with the arm 31 when the end snow plow portion 18 is lowered (FIG. 5), and a stopper surface 33b that interferes with the arm 31 when the end snow plow portion 18 is raised (FIG. 8). And have. Each stopper surface 33a, 33b of the second stopper 33 is provided with a shim plate (not shown) for height adjustment in the raised state and the lowered state, and the raised state is obtained by adjusting the thickness of the shim plate. And the descending state can be adjusted to an appropriate height. A second heater 34 is attached to the second stopper 33. The second heater 34 is attached to a surface of the second stopper 33 that is different from the stopper surfaces 33a and 33b.

  FIG. 6 is a view for explaining the raised state of the elastic obstacle 12 and the end snow plow portion 18 of the obstacle device 10 shown in FIG. 3. FIG. 7 is a view for explaining an elevated state of the elastic obstacle 12 of the obstacle 10 shown in FIG. FIG. 8 is a view for explaining the rising state of the end snow plow portion 18 of the obstruction apparatus 10 shown in FIG. As shown in FIGS. 6 to 8, the first fluid pressure cylinder 13 </ b> A raises and lowers the elastic obstacle 12, and the second fluid pressure cylinder 13 </ b> B raises and lowers the end snow plow portion 18. As the first fluid pressure cylinder 13A and the second fluid pressure cylinder 13B operate independently of each other, the elastic obstacle 12 and the end snow plow portion 18 move up and down independently of each other.

  The elastic obstacle 12 is in a lowered state when traveling in the standard gauge section of the gauge variable vehicle 1 and in an elevated state when traveling in the narrow gauge section of the gauge variable vehicle 1. The end snow plow portion 18 is in a lowered state when traveling in both the standard gauge section and the narrow gauge section of the variable-gauge vehicle 1 and is in an elevated state during traveling in the gauge conversion section between the standard gauge section and the narrow gauge section. When the rod 13Aa of the first fluid pressure cylinder 13A advances downward, the intermediate snow plow portion 20 remains stationary and rotates and rises so that the lower end of the elastic obstacle 12 approaches the upper edge 20e of the notch 20d. When the rod 13Ba of the second fluid pressure cylinder 13B advances downward, the end snow plow portion 18 rotates and rises.

  In the raised state of the elastic obstacle 12, the elastic obstacle 12 is located in the notch 20 d. The raised elastic obstacle 12 is inclined so as to go forward as it goes to the lower end. The inclination angle of the elastic obstacle 12 in the raised state with respect to the vertical line is larger than the inclination angle of the elastic obstacle 12 in the lowered state with respect to the vertical line. The rotation angle of the end snow plow part 18 is larger than the rotation angle of the elastic obstacle 12. The lower end of the end snow plow portion 18 in the raised state is disposed at a position higher than the upper edge 20e of the notch 20d of the intermediate snow plow portion 20.

  According to the configuration described above, the end snow plow portion 18 can be raised when the gauge variable vehicle 1 passes through the gauge conversion device, so that the snow plow 11 is sufficiently long in the vehicle width direction. Also, the snow plow 11 can be prevented from interfering with the gauge conversion device. Further, when traveling in a narrow gauge section, the elastic obstacle 12 is raised while the end snow plow portion 18 is lowered, so that the elastic obstacle 12 is maintained while maintaining the function of the snow plow 11. Can fit inside. Therefore, maintenance of the snow removal function of the snow plow 11, prevention of interference of the snow plow 11 with respect to the gauge change device, and prevention of interference with the construction limit of the elastic obstacle 12 can be realized simultaneously.

  In addition, a notch 20d is formed in the lower portion of the snow plow main body 17 so as to expose the elastic obstacle 12 with a gap from the elastic obstacle 12, so that the first fluid pressure cylinder 13A causes the elastic obstacle. Even if the body 12 rotates and the elastic obstacle body 12 rises so as to approach the snow plow main body portion 17, interference between the elastic obstacle body 12 and the snow plow 11 can be prevented. Further, since the elastic obstacle 12 and the end snow plow portion 18 are moved up and down by rotation instead of sliding, the sticking phenomenon of the sliding portion due to foreign matters such as snow can be prevented, and the maintenance cost can be reduced. In addition, since the elastic obstacle 12 in the raised state is located in the space of the notch 20d, the elastic obstacle 12 functions as a snow guide surface together with the snow guide surface 20a of the intermediate snow plow portion 20 even in the raised state. Can fulfill.

  In addition, since the front surface 28a of the holding member 23 (front member 28) provided on the upper portion of the elastic obstacle body 12 has a shape along the rotation trajectory of the elastic obstacle body 12, the elastic obstacle body 12 is raised. The amount of the gap between the front surface 28a of the holding member 23 and the upper edge 20e of the notch 20d and the amount of the gap between the front surface 28a of the holding member 23 and the upper edge 20e of the notch 20d when the elastic obstacle 12 is lowered. And the difference can be reduced. Therefore, the holding member 23 provided on the upper part of the elastic obstacle 12 is brought close to the upper edge 20e of the notch 20d of the snow plow main body portion 17, and the space between the front surface 28a of the holding member 23 and the upper edge 20e of the notch 20d is set. Intrusion of snow and foreign objects during snow removal can be prevented.

  Moreover, since the end surface 18b on the side of the notch 20d of the end snow plow portion 18 extends outward in the vehicle width direction as it goes downward, the snow hitting the end surface 18b is likely to flow downward, and the end surface It can suppress that 18b accumulates snow. Further, since the end face 18b of the end snow plow portion 18 is formed at an obtuse angle with respect to the snow guide surface 18a of the end snow plow portion 18, the snow that hits the end face 18b of the end snow plow portion 18 is the end snow plow. It becomes easy to flow to the snow guide surface 18a side of the part 18, and it can further suppress that snow accumulates on the end surface 18b.

  Further, the frame 14 is provided with an upper stopper 29A and a lower stopper 29B (lower stopper) that regulate the raising / lowering range of the elastic obstacle 12 and a second stopper 33 that regulates the raising / lowering range of the end snow plow portion 18. Since the impact when the obstacle collides with the elastic obstacle 12 and the end snow plow portion 18 is received by the stoppers 29A, 29B, 33, the impact is not easily transmitted to the drive device 13, and the drive device 13 Failure can be prevented.

  Further, since the upper heater 30A and the lower heater 30B (first heater) are attached to the upper stopper 29A and the lower stopper 29B (first stopper), respectively, and the second heater 34 is attached to the second stopper 33, the upper stopper 29A and Even if snow accumulates in the gap between each of the lower stoppers 29B and the elastic obstacle 12 and the gap between the second stopper 33 and the end snow plow portion 18, the snow is melted by the heaters 30 and 34. Thus, it is possible to prevent the snow from obstructing the raising and lowering of the elastic obstacle 12 and the end snow plow portion 18.

  In addition, this invention is not limited to embodiment mentioned above, The structure can be changed, added, or deleted. For example, the snow plow body portion 17 may not be divided into the central snow plow portion 19 and the intermediate snow plow portion 20. The driving device 13 may be another actuator (for example, an electric motor) instead of the fluid pressure cylinder. The drive device 13 may be an actuator that is used both as the elastic obstacle 12 and the end snow plow portion 18. The facing portion that is provided on the elastic obstacle 12 and faces the upper edge 20e of the notch 20d from the rear may be the upper portion of the elastic obstacle 12 itself instead of the holding member 23.

  Further, the rising operation of the end snow plow 18 is a control in which the control device receives the signal from the ground equipment at the entrance of the gauge conversion section and automatically raises the end snow plow part 18 to a position where it does not interfere with the gauge changing device. It may be implemented by performing the above, or may be implemented by operating a switch or the like that raises the end snow plow portion 18 by the driver by receiving a warning sound or a display device to receive the signal. In addition, when the control device automatically raises the end snow plow portion 18 in response to a signal from the ground facility, the driver may confirm a display indicating completion of the rise.

  Further, the descending operation of the end snow plow 18 may be performed by the control device receiving a signal from the ground facility at the exit of the gauge variable section and performing control to automatically descend the end snow plow portion 18. Alternatively, the driver may be operated by operating a switch or the like for lowering the end snow plow portion 18 by receiving the signal and giving a warning with a warning sound or a display device.
