It is fixed by a bolt 61 or the like so that the height can be adjusted. A boss 62 is fixed to the center of the top plate of the support frame 59, and a shaft 64 of a rotary brush 63 formed in a cup shape by a wire is inserted into the boss 62. A spring receiver 65 is attached to a lower portion of the shaft 64, and a coil spring 66 is interposed between the boss 62 and the spring receiver 65 on the outer periphery of the shaft 64. A motor 67 and its speed reducer 68 are supported on the top plate of the support frame 59, and the speed reducer 68 is linked to the shaft 64.

As described above, the deicing device 39 is configured such that the orbits of the track running wheels 4 and 5 correspond to the intervals of the standard track 8a or the intervals of the narrow track 8b as the hydraulic cylinder 26 expands and contracts. The rotating brush 63 is set so as to correspond to the upper surface of the standard trajectory 8a or the upper surface of the narrow trajectory 8b. In addition, as described above, along with the expansion and contraction of the hydraulic cylinder 20, the track traveling wheels 4, 5 and the like descend and descend (see solid lines in FIGS. 1 and 7), or the track traveling wheels 4, 5 and the like rise. (See dashed lines in FIGS. 1 and 7). Then, by adjusting the height of the rotary brush 63 using the long hole 60 as described above, the rotary brush 63 is pressed against the upper surface of the standard track 8a or the narrow track 8b with an appropriate pressing force of the coil spring 66. It has become so. Further, when the deicing device 39 is not used except in winter, the bolts 57 and 58 are removed to detach the arms 55 and 56 from the support portion 14 so that the rotating brush 63 is removed.

As shown in FIG. 9, an exhaust blowing pipe 72 is branched through a valve 71 housed in a branch box 70 in the middle of the exhaust pipe 69, and the tip of the exhaust blowing pipe 72 is located in front of the rear wheels 3 a and 3 b with tires. At the upper surface of the narrow track 8b. Therefore, in winter, by switching the valve 71 by operating the switching lever 73, warm traveling exhaust can be blown from the exhaust blowing pipe 72 to the upper surface of the narrow track 8b when traveling on the narrow track 8b. In the illustrated example, the exhaust blowing pipe 72 corresponds to only the upper surface of the narrow track 8b. However, for example, the exhaust blowing pipe 72 may be configured to be extendable or contractable, or may be branched from the exhaust pipe 69 at another location via a valve. By doing so, it is possible to blow warm exhaust air onto the upper surface of the standard track 8a even when traveling on the standard track 8a.

The operation of the above configuration will be described below. In seasons other than winter, the snow removing device 38 and the ice removing device 39 are previously removed from the work cart 1 as described above, and the piston rod 21 of the hydraulic cylinder 20 is further contracted as described above to reduce 4 and 5 are held in the raised positions as shown by the dashed line in FIG. 1 and the dashed line in FIG. And the wheels 3a, 3b with tires
By driving on the road, the vehicle travels on a road or the like, enters a railroad crossing near the work site, and stops at a position where the turning device 7 is located at the center of the gauge.

Next, as described above, the distance between the track running wheels 4, 4, 5 and 5 is made to correspond to the distance between the standard track 8a or the narrow track 8b by the expansion and contraction of the piston rod 27 of the hydraulic cylinder 26 (FIG. 8). reference). Next, the whole of the work cart 1 and the like is raised by driving the turning device 7, and is rotated by about 90 degrees by human power, and the standard track 8a or the narrow track 8b is rotated.
When the front left and right track running wheels 4 and the rear left and right track running wheels 5 corresponding to the distance between the front and rear tracks coincide with the standard track 8a or the narrow track 8b, first, the piston rod of the hydraulic cylinder 20 is moved as described above. The track running wheels 4 and 5 are lowered as shown in the solid line in FIG. 1, the solid line in FIG. 7 and FIG. Subsequently, the entire work cart 1 and the like are lowered by driving the turning device 7, and the track running wheels 4 and 5 are moved to the standard track 8a or narrow as shown in FIG. 1, FIG. 3, FIG. 7, and FIG. Along with the track 8b, the rear left and right wheels 3a or 3b with tires are mounted on the standard track 8a or the narrow track 8b. By driving the rear left and right wheels with tires 3a and 3b in this state, the work cart 1 is caused to travel to a desired work site by the work device 31 and the track running wheels 4 and 5 mounted thereon. Can do the work.

After the work is completed, the work cart 1 is moved to the work device 31.
In the same manner as described above, the vehicle is driven to a railroad crossing close to the work site, and while the work cart 1 and the like are supported at the ascending position by the driving of the turning device 7, the piston rod 2 of the hydraulic cylinder 20 is moved.
1 is retracted to raise the orbit wheels 4 and 5, and the work cart 1 and the like are rotated by approximately 90 degrees. Subsequently, the work cart 1 and the like are lowered by driving of the turning device 7, and the front and rear left and right wheels 2 and 3a and 3b are landed, whereby the vehicle can travel on a road or the like.

In winter, when traveling on the standard track 8a to perform work, the standard track 8a is controlled by an obstacle such as a train.
Since the snow is removed to the outside of the vehicle, there is no hindrance to running, and the work can be performed in the same manner as described above.
By the way, in winter, when traveling on the narrow track 8b to perform work, ice and snow removed to the outside of the narrow track by an obstacle such as a train protrudes outward from the narrow track 8b. This impedes the passage of the wheels 3a.

Therefore, the snow removing device, the snow removing device 38 and the ice removing device 39 are previously attached to the work cart 1 as described above, and the hydraulic cylinder 47 is further contracted to hold the snow removing device 38 at the raised position as described above. Then, the hydraulic cylinder 20 is contracted to keep the track running wheels 4, 5 and the deicing device 39 at the raised position. Then, the vehicle travels on a road or the like by driving the wheels with tires 3a and 3b, enters a railroad crossing near the work site, and stops at a position where the turning device 7 is at the center between the gauges.

Next, as described above, the hydraulic cylinder 26 is contracted to reduce the distance between the track running wheels 4, 4, 5 and 5 to the narrow track 8b.

Is brought close to the track surface, the track running wheels 4, 5 and the rotating brush 63 of the deicing device 39 are mounted on the narrow track 8b, and the rear left and right wheels 3b with tires are mounted on the narrow track 8b.

Then, the snow removal teeth 5 are driven by driving the motor 54.
3 is rotated, and the rotating brush 63 is driven by the motor 67.
To switch the valve 69 to the exhaust blowing pipe 72 side facing the narrow track 8b. In this state, by driving the rear left and right tire wheels 3a, 3b, the work cart 1 is moved to a desired work site by the track running wheels 4, 5 together with the work device 31 mounted thereon. Can do the work. At this time, the snow removal device 38
The ice and snow removed by the snow removing teeth 53 to the outside of the narrow track 8b is crushed and removed so as not to hinder the passage of the rear outer wheel 3a with the tire projecting to the outside of the narrow track 8b. In addition, the rotation of the rotating brush 63 and the discharge of exhaust gas from the exhaust blowing pipe 72 removes ice on the narrow raceway surface to prevent the wheels 3b with tires from slipping, thereby allowing the vehicle to travel safely. it can.

After the operation is completed, the driving of the motors 54 and 67 is stopped to stop the rotation of the snow removal teeth 53 and the rotating brush 63, and the valve 71 is switched to the exhaust pipe 69 side. In the same manner as described above, the vehicle is driven to a railroad crossing near the work site, the hydraulic cylinder 49 is contracted to raise the snow removing device 38 while the work cart 1 and the like are supported at the raised position by driving the turning device 7, and the hydraulic pressure is increased. The cylinder 20 is contracted to raise the orbit wheels 4, 5 and the deicing device 39, and the work cart 1 and the like are rotated by approximately 90 degrees. Subsequently, the work cart 1 and the like are lowered by driving of the turning device 7, and the wheels 2 and 3a, 3a, 3
By landing b, it is possible to travel on a road or the like.

When a long time is required for the work and the upper surface of the narrow track 8b is frozen, the work cart 1 and the like are inverted by the turning device 7, and the rotation of the rotating brush 63 of the deicing device 39 and the deicing are performed. It is also possible to travel in the opposite direction while removing the ice on the narrow raceway surface by spraying the exhaust gas from the exhaust spray pipe 72 of the device 40. Also, as described above, the standard orbit 8a
When traveling, the ice and snow removed to the outside of the standard track 8a does not hinder the traveling.
Is not necessary, but when the upper surface of the standard track 8a is frozen, the rotation of the rotating brush 63 of the deicing device 39 and the exhaust from the exhaust blowing pipe are performed as in the case of traveling on the narrow track 8b.
