<< Operation of Rail Tread Cleaning Device 1 of this Embodiment >>
Next, operation | movement of the rail tread cleaning apparatus 1 of this embodiment comprised as mentioned above is demonstrated.

<When the rail tread cleaning device 1 of the present embodiment moves forward>
1 to 4 and the like, the rail tread cleaning device 1 is connected to the front of the track bicycle 2 via the connecting rod 12, and when the track bicycle 2 moves forward in the left direction in the figure, the track bicycle 2 is connected to the front of the track bicycle 2. The rail tread cleaning device 1 of this embodiment thus pushed is also pushed forward.

  Then, the wheels 11c and 11c provided on the left and right sides of the carriage main body 11 of the rail tread cleaning truck 11 and the rotary shaft 11b rotate, and the drive gear 11d provided on the rotary shaft 11b also rotates with the wheels 11c and 11c. It rotates in the same direction as the shaft 11b.

  In the rotation transmission mechanism 11e, the first transmission gear 11e1 meshed with the drive gear 11d rotates in the direction opposite to the rotation direction of the wheels 11c, 11c and the drive gear 11d by the rotation of the drive gear 11d, and the transmission shaft portion 11e2. The second transmission gear 11e3 composed of a bevel gear or the like also rotates in the direction opposite to the rotation direction of the wheels 11c, 11c and the drive gear 11d.

  In the rail tread cleaning mechanism portion 11f, the multi-stage passive gear 11f3 provided on the rear end side of the rotary shaft portion 11f2 meshing with the second transmission gear 11e3 rotates in the opposite direction to the second transmission gear 11e3. The wheels 11c and 11c and the drive gear 11d rotate in the same direction as the rotation direction.

  Then, the rotating brush 11f4 provided on the distal end side of the rotating shaft portion 11f2 rotates in the same direction as the rotation directions of the wheels 11c and 11c and the driving gear 11d together with the rotating shaft portion 11f2 by the rotation of the multistage passive gear 11f3.

  That is, when the rail tread cleaning device 1 of the present embodiment is also advanced by the advancing track bicycle 2, the rotation of the wheels 11c and 11c is transmitted to the rotation transmission mechanism 11e via the rotation shaft 11b and the drive gear 11d, and the rotation transmission is performed. The rotating brush 11f4 is transmitted from the mechanism 11e to the rail tread cleaning mechanism 11f, and rotates in the same direction as the rotation direction of the wheels 11c and 11c and the drive gear 11d.

  Here, the rotating shaft portion 11f2 of the rail tread cleaning mechanism portion 11f is provided on each side of the carriage main body 11a at an oblique angle with respect to the traveling direction, specifically, at an angle of 45 degrees. As shown in FIGS. 4 to 6 and the like, the rotating shaft portions 11f2 provided on both sides of the cart body 11a have rear end portions projecting inside the cart body 11a, while the tip portion to which the rotating brush 11f4 is attached is the cart. It protrudes to the outside of the main body 11a, is provided in front of the wheels 11c, 11c of the rotating brush 11f4 carriage main body 11a, and runs on the left and right rails R.

  Since the rotating brush 11f4 on the rail R rotates in the same direction as the rotation direction of the wheels 11c, 11c and the drive gear 11d, the left and right rotating brushes 11f4 are respectively stacked on the rail R by rotating. The fallen ash such as volcanic ash is put on the outer side obliquely rearward with respect to the traveling direction of the carriage main body 11a.

  Therefore, according to the rail tread cleaning apparatus 1 of the present embodiment, even when the rotation source of the engine or motor cleaner means 11f is not mounted, volcanic ash and the like accumulated on the rail R can be removed. The volcanic ash accumulated on the R can be swept out of the rail R without being swept between the rails R, and the volcanic ash can be efficiently removed.

The projection 11e31 protruding from the center of the gear 11e3 fits in the slide guide groove 11e21 and is guided and slid, so that the second transmission gear 11e3 made of a bevel gear or the like can move in the longitudinal direction of the transmission shaft 11e2. The transmission shaft portion 11e2 can be rotated together.

  The multi-stage passive gear 11f3 of the rail tread cleaning mechanism portion 11f is formed with a slide guide groove 11f21 having a predetermined length so that the two passive gears 11f31 and 11f32 having different numbers of teeth can slide. The projection 11f33 protruding from the center of the multi-stage passive gear 11f3 fits and slides in the slide guide groove 11f21, and the passive gears 11f31 and 11f32 move in the longitudinal direction of the rotary shaft portion 11f2 to transmit. The rotational speed of the rotating brush 11f4 can be changed by meshing the first-stage passive gear 11f31 with the second transmission gear 11e3 made of a bevel gear or the like of the shaft portion 11e2, or by meshing the second-stage passive gear 11f32. It is configured.

  Therefore, in this embodiment, when changing the rotation speed of the rotating brush 11f4, the second transmission gear 11e3 made of a bevel gear or the like in the transmission shaft portion 11e2 is slid along the slide guide groove 11e21, and the rail tread The multi-stage passive gear 11f3 of the cleaning mechanism 11f is also slid along the slide guide groove 11f21 to change the passive gears 11f31 and 11f32 of the multi-stage passive gear 11f3 with which the second transmission gear 11e3 made of a bevel gear or the like meshes. By doing so, the rotation speed of the rotating brush 11f4 can be changed.
