Description

  The present invention relates to a snow removal device, a vehicle, and a track traffic system.

  As a new means of transportation other than buses and railroads, a track-type traffic system that travels on a track by running wheels made of rubber tires or the like is known. Such a track traffic system is generally called a new traffic system or an APM (Automated People Move).

  A vehicle employed in such a track-type traffic system includes, for example, a current collector provided on a side surface thereof, and a guide wheel provided alongside the current collector. In addition, on the track on which the vehicle travels, a train line for supplying power to the vehicle via the current collector of the vehicle and a guide rail for guiding the traveling direction of the vehicle by contacting the vehicle guide wheels are provided. It has been. Therefore, the vehicle in the track system travels along the guide rail while supplying power by bringing the current collector into contact with the train line. Vehicles of such track-based traffic systems are often driven unattended, and snow accumulated by snowfall may interfere with traffic.

  In order to remove such snow, for example, Patent Document 1 discloses a guide rail type on-track object removal device for a vehicle that can remove on-track objects such as snow and foreign matter. Specifically, the on-orbit object removal device of Patent Document 1 is a lifting device that moves up and down a frame provided in front of the traveling direction of a wheel and a brush holder attached to the frame and holding an on-orbit object removal brush. And. This on-orbit object removal device removes the on-orbit object by pressing the brush holder downward by the lifting device and bringing the on-orbit object removal brush into contact with the road surface.

JP 2010-241312 A

  By the way, in the apparatus described in Patent Document 1 described above, the on-orbit object is removed by pushing the on-orbit object removal brush in the traveling direction of the vehicle with the vehicle in contact with the road surface. However, simply pressing the on-orbit object removal brush in the traveling direction by the vehicle increases the amount of snow pushed by the on-orbit object removal brush when a large amount of snow is piled up on the road surface. Therefore, the load on the brush is increased, and the frictional force between the brush and the road surface is increased. As a result, the amount of wear of the brushes increases, so that it is necessary to replace the on-orbit object removal brush before sufficiently removing snow, and it is difficult to efficiently remove snow on the road surface.

  The present invention has been made to solve the above-described problems, and is a snow removal device, a vehicle, and a track system traffic that can efficiently remove snow accumulated on a travel path while suppressing wear of a brush. A system is provided.

In order to solve the above problems, the present invention proposes the following means.
According to a first aspect of the present invention, there is provided a snow removal device having a lower end from a traveling path of the track, which is in contact with the traveling wheel, in front of a traveling direction of the traveling body of the traveling vehicle provided on the vehicle body traveling on the track. Is attached to the vehicle main body so as to be separated from each other, and the snow main body moves in the vehicle width direction of the vehicle main body when the vehicle main body moves toward the front in the driving direction. And the lower end of the snow plow portion in the traveling direction and the front of the traveling wheel in the traveling direction, the lower end contacting the traveling path, and at least a part when viewed from the front in the traveling direction. A snow removal brush portion attached to the vehicle main body so as to be disposed at a position overlapping the snow plow portion.

  According to such a configuration, when the vehicle body travels while receiving snow at the snow plow portion, the snow accumulated on the travel path is moved toward the vehicle width direction and removed from the front in the travel direction of the traveling wheels. be able to. Furthermore, the snow remaining between the lower end of the snow plow part and the travel path without being removed by the snow plow part is moved in the vehicle width direction so as to be swept away by bringing the snow removal brush part into contact with the travel path. Can do. Therefore, by removing much of the snow on the road with the snow plow part, the load on the snow removal brush part is suppressed, while the snow plow part removes a little snow remaining on the road that is difficult to remove with the snow plow part with high accuracy. Can be removed.

  In the snow removal device, the snow plow portion has a receiving surface that is formed to be inclined in the vehicle width direction with respect to the traveling direction and receives the snow, and the snow removal brush portion is the same as the receiving surface. You may have a brush part main body which inclines in a direction and contacts the said travel path.

  According to such a configuration, the receiving surface of the snow plow portion and the snow removal brush portion are disposed to be inclined in the same direction in the vehicle width direction with respect to the traveling direction. Therefore, it is possible to send the snow accumulated on the traveling road by the receiving surface and the snow removal brush portion so as to be pushed out in the vehicle width direction only by moving the vehicle body forward in the traveling direction. Therefore, it is possible to improve the ability to remove the snow accumulated on the traveling road in the vehicle width direction.

  Further, in the snow removal device, the receiving surface is curved in a convex shape rearward in the traveling direction toward the upper side in the vertical direction, and is directed forward in the traveling direction and in the vehicle width direction. The radius of curvature may be increased toward the one side.

  According to such a configuration, the receiving surface is formed so as to cover the snow ahead of the snow plow portion in the traveling direction while the curvature radius increases toward one side in the vehicle width direction. For this reason, even if the amount of snow received on the receiving surface increases toward the one side in the vehicle width direction by moving the vehicle body forward in the traveling direction, it spills backward in the traveling direction beyond the snow plow. Can be suppressed. Thereby, it is possible to stably remove snow on one side in the vehicle width direction.

  Moreover, in the said snow removal apparatus, the said receiving surface may be extended and formed in the upper side of a perpendicular direction as it goes to the one side of the said vehicle width direction.

  According to such a configuration, the amount of snow that can be received on the receiving surface can be increased toward the one side in the vehicle width direction by moving the vehicle body forward in the traveling direction. Therefore, even if the amount of snow received by the receiving surface increases toward one side in the vehicle width direction, it is possible to further suppress spilling over the snow plow portion and rearward in the traveling direction. Thereby, snow can be sent to one side in the vehicle width direction more stably and removed.

  Moreover, in the said snow removal apparatus, the said receiving surface may be formed in the downward direction from the center part of the perpendicular direction, curving toward the front of the said traveling direction with respect to the vertical line.

  According to such a configuration, the snow applied to the snow plow portion due to warpage can be reliably sent to the vehicle width direction without flowing downward in the vertical direction, and the snow removal efficiency of the snow plow portion itself is improved. Can be made.

  Moreover, in the said snow removal apparatus, the said snow removal brush part may be attached to the said vehicle main body integrally with the said snow plow part, and may be movable to a perpendicular direction with respect to the said travel path.

  According to such a configuration, the snow removal brush part and the snow plow part can be moved together vertically in the vertical direction with respect to the traveling road, so that normal operation that does not require snow removal on the traveling road where snow is not falling is possible. Occasionally, the snow removal brush part and the snow plow part are greatly separated from the road, and only when snow removal is necessary, the snow plow part is brought close to the road and the lower end of the snow removal brush part is brought into contact with the road. Can do. Accordingly, it is possible to suppress traveling while the lower end of the snow removal brush portion is in contact with the traveling path during normal operation, and it is possible to prevent the snow removal brush portion from being worn.

  Moreover, in the said snow removal apparatus, the said snow removal brush part may be attached to the said vehicle main body independently of the said snow plow part, and shall be movable to a perpendicular direction with respect to the said travel path.

  According to such a configuration, only the snow removal brush portion can be largely separated from the travel path. Therefore, it is possible to remove snow accumulated on the traveling road only by the snow plow portion.

  Moreover, the vehicle in the 2nd aspect of this invention is provided with the vehicle main body which has a snow removal apparatus.

  Moreover, the track-type traffic system in the third aspect of the present invention includes the vehicle and a track on which the vehicle body travels.

  According to such a configuration, the vehicle can be efficiently driven while removing snow accumulated on the road. For this reason, it is possible to suppress the disturbance of the diamond and the train delay due to the snow.

  According to the present invention, by removing snow on the traveling road by the snow plow part and the snow removal brush part, it is possible to efficiently remove snow accumulated on the traveling road while suppressing wear of the brush.

Further, the snow remaining between the lower end of the snow plow portion 61 and the traveling path 21a is pushed so as to be swept out by the brush portion main body 621 supported from the rear in the traveling direction Dr by the support roller 634b. It is removed toward the outside in the width direction Dw.

  According to the snow removal device 60 as described above, the vehicle body 51 travels while receiving snow on the receiving surface 61a of the snow plow part 61, so that the snow accumulated on the travel path 21a is directed outward in the vehicle width direction Dw. To remove the traveling wheel 511 from the front in the traveling direction Dr. Furthermore, the snow remaining between the lower end of the snow plow part 61 and the travel path 21a without being removed by the snow plow part 61 is swept away by bringing the lower end of the brush body 621 into contact with the travel path 21a. To the outside in the vehicle width direction Dw. Therefore, by removing much of the snow on the travel path 21a with the snow plow part 61, while suppressing the load on the brush part main body 621, the snow plow part 61 removes a little snow remaining on the travel path 21a that is difficult to remove. The brush body 621 can be removed with high accuracy. Thereby, a large amount of snow can be easily removed while suppressing wear of the brush portion main body 621.

  For example, when a large amount of snow of several tens of centimeters is accumulated on the traveling path 21a, if the snow is removed only by the snow removal brush portion 62, a large amount of snow is pushed out by the brush portion main body 621. Therefore, a load is applied to the brush portion main body 621, and the frictional force generated between the traveling path 21a and the lower end of the brush portion main body 621 is increased. As a result, the amount of wear of the brush portion main body 621 increases and exceeds the wear limit, so that the length on which the snow on the travel path 21a can be removed cannot be secured, and the snow on the travel path 21a is sufficiently removed. There is a possibility that the snow removal brush portion 62 needs to be replaced before the removal.

  Further, the snow plow portion 61 is made of a highly rigid material that is difficult to be deformed, such as a metal material, and therefore cannot be moved while being in contact with the travel path 21a. Therefore, it is necessary to form a gap between the travel path 21 a and the snow plow portion 61. However, since there is a gap between the travel path 21 a and the snow plow part 61, snow remains on the travel path 21 a even if snow is removed only by the snow plow part 61.

  In the case of a railway that travels on a rail by wheels instead of the traveling wheels 511, the surface pressure between the wheels and the rails is high, so no problem occurs even if some snow remains. However, when the traveling wheels 511 such as rubber tires are moved in contact with the traveling road 21a as in the vehicle 5 used in the track-type traffic system 1, the traveling wheels 511 slip and move due to snow remaining. It becomes an obstacle to doing.

  Also, in the case of an automobile, the same rubber tire is used, but it is possible to easily take measures against snow accumulation such as mounting a tire chain or replacing the tire with a studless tire. However, since the running wheels 511 such as rubber tires used in the track system 1 are very large and weigh several hundred kg, the running wheels 511 can be removed and equipped with tire chains or replaced with studless tires. It is difficult to take measures against snow accumulation.

  On the other hand, in this embodiment, by using the snow plow part 61 and the snow removal brush part 62, the snow plow part 61 removes most of a large amount of snow on the travel path 21a, while the brush part main body 621 uses the travel path 21a. A little snow remaining on the top can be removed with almost no residue. Therefore, even when it is snowing, it is possible to remove almost no snow on the travel path 21a, and the vehicle main body 51 can be traveled without taking measures against snow accumulation on the travel wheels 511.

  Further, the receiving surface 61a and the brush portion main body 621 are disposed to be inclined from 40 ° to 45 ° outside the vehicle width direction Dw with respect to the traveling direction Dr. Therefore, only by moving the vehicle main body 51 forward in the traveling direction Dr, the receiving surface 61a and the brush portion main body 621 send the snow accumulated on the traveling path 21a so as to push it outward in the vehicle width direction Dw. Can do. Therefore, it is possible to improve the ability to remove the snow accumulated on the travel path 21a toward the outside in the vehicle width direction Dw.

  Moreover, in the snow plow part 61, the vehicle main body 51 moves, so that the receiving surface 61a sends snow to the outside in the vehicle width direction Dw while receiving snow. However, as the amount of snow accumulated on the travel path 21a increases, the amount of snow received by the receiving surface 61a gradually increases toward the outside in the vehicle width direction Dw in the process of sending snow to the outside in the vehicle width direction Dw. Resulting in.

  However, as in the present embodiment, the receiving surface 61a is curved in a convex shape behind the traveling direction Dr as it goes upward in the vertical direction Dv, while facing the front of the traveling direction Dr, and the vehicle width. The curvature radius is formed so as to increase toward the outside of the direction Dw. That is, the receiving surface 61a is formed so as to cover the snow in front of the traveling direction Dr from the snow plow part 61 from the upper side in the vertical direction while the radius of curvature increases toward the outside in the vehicle width direction Dw. Therefore, even if the amount of snow received by the receiving surface 61a increases toward the outside in the vehicle width direction Dw by moving the vehicle body 51 forward in the traveling direction Dr, the traveling direction exceeds the snow plow portion 61. Spilling behind Dr can be suppressed. Thereby, it is possible to stably remove snow by sending it to the outside in the vehicle width direction Dw.

  Further, since the receiving surface 61a extends upward in the vertical direction Dv toward the outside in the vehicle width direction Dw, snow that can be received by the receiving surface 61a as it goes outside in the vehicle width direction Dw. The amount can be increased. Therefore, even if the amount of snow received by the receiving surface 61a increases toward the outer side in the vehicle width direction Dw, it is possible to further suppress spilling beyond the snow plow portion 61 in the traveling direction Dr. Thereby, snow can be sent to the outside in the vehicle width direction Dw more stably.

  A brush fixing portion 622 is attached to the second arm portion 633b integrally with the snow plow portion 61, and is fixed to the piston portion 632b via the first arm portion 633a. Therefore, the brush part main body 621 and the snow plow part 61 can be moved up and down in the vertical direction Dv with respect to the guide frame 521 and the travel path 21a. As a result, during normal operation that does not require snow removal on the travel path 21a where it is not snowing, the brush body 621 and the snow plow part 61 are separated greatly from the travel path 21a, and only when snow removal is required The snow plow part 61 can be brought close to the road 21a, and the lower end of the brush part main body 621 can be brought into contact with the traveling path 21a. Accordingly, it is possible to suppress traveling while the lower end of the brush part body 621 is in contact with the traveling path 21a during normal operation, and it is possible to prevent the brush part body 621 from being worn. Further, when the brush unit main body 621 comes into contact with the travel path 21a, friction is generated and the vehicle main body 51 is inhibited from traveling. For example, the snow plow unit 61 and the brush unit main body 621 affect the traveling of the vehicle main body 51 during normal operation. It can be suppressed.

  Further, since the vehicle 5 including the snow removal device 60 as described above is connected to the head of the traveling direction Dr, the vehicle 5 can be efficiently traveled while removing the snow accumulated on the travel path 21a. For this reason, it is possible to suppress the disturbance of the diamond and the train delay due to the snow.

<< Second Embodiment >>
Next, the snow removal device 70 of the second embodiment will be described with reference to FIG.
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The snow removal device 70 of this second embodiment is different from the first embodiment in that the snow removal brush portion 62 is attached to the vehicle main body 51 independently of the snow plow portion 61.

The snow removal device 70 of the second embodiment has a plow fixing portion 71 for attaching the snow removal brush portion 62 to the vehicle main body 51 independently of the snow plow portion 61.
Further, the second arm portion 733b of the second embodiment is not connected to the snow plow portion 61, and is connected to the first arm portion 633a by fixing only the brush fixing portion 622.

  The plow fixing part 71 fixes the snow plow part 61 so as not to move with respect to the traveling path 21a. The plow fixing portion 71 of the present embodiment is configured so that the snow plow portion 61 is positioned so that the lower end of the snow plow portion 61 is separated from the travel path 21a by a predetermined length from the wear limit amount of the snow removal brush portion 62. It is attached to the vehicle body 51. Specifically, the plow fixing portion 71 fixes the snow plow portion 61 so that the lower end of the snow plow portion 61 is located about 50 mm to 60 mm away from the travel path 21a, as in the first embodiment. .

  In the plow fixing portion 71 of this embodiment, the rear of the traveling direction Dr is fixed to the cylinder portion 632a, and the front of the traveling direction Dr is fixed to the snow plow portion 61. The plow fixing | fixed part 71 is being fixed to the lower end of the surface which faces the outer side of the traveling path 21a in the vehicle width direction Dw of the cylinder part 632a. That is, the plow fixing portion 71 is provided side by side with the first arm portion 633a in the vertical direction Dv when viewed from the outside in the vehicle width direction Dw. The plow fixing part 71 is provided in each cylinder part 632a. Therefore, the plow fixing portion 71 holds the snow plow portion 61 so as to be sandwiched from both sides in the vehicle width direction Dw by the two plow fixing portions 71 arranged apart in the vehicle width direction Dw.

  According to the snow removal device 70 as described above, only the brush portion main body 621 can be moved up and down in the vertical direction Dv with respect to the guide frame 521 and the travel path 21a. Therefore, during normal operation that does not require snow removal on the travel path 21a where it is not snowing, the brush body 621 can be greatly separated from the travel path 21a. Therefore, similarly to the first embodiment, it is possible to prevent the brush portion main body 621 from being worn and to prevent the brush portion main body 621 from being worn during normal operation by preventing the lower end of the brush portion main body 621 from being in contact with the traveling path 21a. it can.

  Moreover, since the brush part main body 621 is attached to the attachment support part 63 separately from the snow plow part 61, only the brush part main body 621 can be largely separated from the traveling path 21a. Therefore, for example, when the snow has accumulated on the travel path 21a to a height that is difficult to remove with the brush part main body 621, it is possible to remove the snow that has been accumulated on the travel path 21a only by the snow plow part 61 alone.

  Note that, as in the second embodiment, the snow plow portion 61 is not limited to a structure that is attached to the vehicle main body 51 in a fixed state, and the vehicle main body 51 is independent of the snow removal brush portion 62. It only has to be attached to. For example, the snow plow part 61 of the second embodiment may be attached so as to be movable up and down in the vertical direction Dv with respect to the travel path 21a independently of the snow removal brush part 62. By adopting such a structure, the snow plow part 61 can be moved to an arbitrary position in the vertical direction Dv according to the state of snow accumulated on the travel path 21a regardless of the position of the brush part main body 621. it can.

  Although the embodiments of the present invention have been described in detail with reference to the drawings, the configurations and combinations of the embodiments in the embodiments are examples, and the addition and omission of configurations are within the scope not departing from the gist of the present invention. , Substitutions, and other changes are possible. Further, the present invention is not limited by the embodiments, and is limited only by the scope of the claims.
