Snow removal device, vehicle, and track transportation system

Abstract

A snow removal device includes: a snow plow part that is mounted on a vehicle body traveling along a track in front of running wheels in which the vehicle body travels such that a lower end is separated from each of runways of the track with which the running wheels contact and that displaces forward snow of the running direction in a vehicle width direction as the vehicle body moves forward in the running direction; and a snow removal brush part mounted on the vehicle body in a rear of the snow plow part in the running direction and in front of the running wheels in the running direction so as to be disposed at a position at which a lower end thereof contacts the runway and at a position at which at least a portion thereof overlaps the snow plow part when viewed from the front.

What is claimed is: 
     
         1 . A snow removal device comprising:
 a snow plow part that is mounted on a vehicle body traveling along a track in front of running wheels provided for the vehicle body in a running direction in which the vehicle body travels such that a lower end of the snow plow part is separated from each of runways of the track with which the running wheels are in contact and that displaces forward snow of the running direction in a vehicle width direction of the vehicle body as the vehicle body moves forward in the running direction; and   a snow removal brush part that is mounted on the vehicle body in a rear of the snow plow part in the running direction and in front of the running wheels in the running direction so as to be disposed at a position at which a lower end of the snow removal brush part comes into contact with the runway and at a position at which at least a portion of the snow removal brush part overlaps the snow plow part when viewed from the front in the running direction.   
     
     
         2 . The snow removal device according to  claim 1 , wherein:
 the snow plow part includes a reception surface that is formed to be inclined in the vehicle width direction with respect to the running direction and receives the snow; and   the snow removal brush part includes a brush part body that is inclined in the same direction as the reception surface and comes into contact with the runway.   
     
     
         3 . The snow removal device according to  claim 2 , wherein the reception surface extends forward in the running as going upward in a vertical direction while being curved in a shape recessed backward in the running direction, and is curved such that a radius of curvature is increased as going toward the vehicle width direction. 
     
     
         4 . The snow removal device according to  claim 2 , wherein the reception surface is formed by extending upward in the vertical direction as going toward the vehicle width direction. 
     
     
         5 . The snow removal device according to  claim 3 , wherein the reception surface is formed by extending upward in the vertical direction as going toward the vehicle width direction. 
     
     
         6 . The snow removal device according to  claim 2 , wherein the reception surface is formed in such a manner that a lower portion of the reception surface below a central portion of the reception surface in the vertical direction is warped forward in the running direction with respect to a vertical line. 
     
     
         7 . The snow removal device according to  claim 3 , wherein the reception surface is formed in such a manner that a lower portion of the reception surface below a central portion of the reception surface in the vertical direction is warped forward in the running direction with respect to a vertical line. 
     
     
         8 . The snow removal device according to  claim 4 , wherein the reception surface is formed in such a manner that a lower portion of the reception surface below a central portion of the reception surface in the vertical direction is warped forward in the running direction with respect to a vertical line. 
     
     
         9 . The snow removal device according to  claim 5 , wherein the reception surface is formed in such a manner that a lower portion of the reception surface below a central portion of the reception surface in the vertical direction is warped forward in the running direction with respect to a vertical line. 
     
     
         10 . The snow removal device according to  claim 1 , wherein the snow removal brush part is mounted on the vehicle body as one body with the snow plow part and is movable relative to the runway in a vertical direction. 
     
     
         11 . The snow removal device according to  claim 1 , wherein the snow removal brush part is mounted on the vehicle body independently of the snow plow part and is movable relative to the runway in a vertical direction. 
     
     
         12 . A vehicle comprising the vehicle body including the snow removal device according to  claim 1 . 
     
     
         13 . A track transportation system comprising:
 the vehicle according to  claim 12 ; and   a track along which the vehicle body travels.
