ONBOARD SNOW PLOW

The invention relates to snow plows for use on railways, tracks and yards.

It is already known, for example, from Finnish patent no. A locomotive snow plow according to 74316, which plows or rolls snow, e.g. starting from the left side of the yard all the way to the next track. The next run will roll over the next track again and thus always continue until the entire yard is plowed by rolling the snow from left to right in this case.

The disadvantage of the above-mentioned plow is that the locomotive must always be driven back first and thus only plow in the same direction, because the plow wings always direct the snow to the same side of the locomotive.

The object of the present invention is to provide a locomotive snow plow for reciprocating, i.e. the locomotive rapidly changes the position of the snow blades and plows in both directions and if necessary the locomotive immediately performs shift work in both directions normally so that buffers or center bus are visible at both ends.

The features of the invention are set out in claim 1.

The invention will be explained in more detail with the aid of the accompanying drawings.

Figure 1 shows a side view of a plow according to the invention placed on a railcar or locomotive and with the locomotive driving backwards in Figures 1 and 2 and the snow moving to the left in the direction of travel of the locomotive.

Figure 2 shows the same locomotive seen from above.

Figure 3 shows the same locomotive seen from the right when plowing takes place viewed from the right in the direction of travel.

Figure 4 shows a top view of the same locomotive when plowing is to the right.

Figure 5 shows a front view of a locomotive according to the invention with the plow blades facing the side, i.e. in the shifting position.

Figures 4 to 6 show the flow of snow schematically. A - B - C -D / Λ '- B' -C - D \

The invention is characterized in that the snow plow locomotive acts as a locomotive or change locomotive immediately if necessary, whereby buffers and switches are visible and usable at both ends, and in the snow area the snow plow locomotive immediately acts as a snow plow in both directions or rolls snow over the adjacent track.

The invention is based on the fact that at each end of the locomotive there is a plowing blade mounted on a column close to the end angle of the locomotive, which can be raised and lowered and also turned to the side of the locomotive and from there to different plowing positions.

Figures 1 and 2 show the position of the plow blade 1 behind the locomotive when driving backwards and the position of the plow blade 2 in front of the locomotive when the snow is plowed while driving the locomotive backwards and the snow flies to the left.

In Fig. 2, the plowing wing 1 is turned from the left side of the locomotive into a front wing and the wing 2 from the same side of the locomotive from the front end of the locomotive into the left rear wing.

The front wing 1 is mounted near a column 3 located near the left corner of the rear end of the locomotive. With the hydraulic cylinder 5, the wing 1 is raised on the side of the locomotive and turned to the plowing position. In Fig. 2, the outer end of the hydraulic cylinder 7 fixed to the locomotive buffer plate at point 9 is fixed to the outer pillar 13 of the wing 1.

The plowing blade 2 is raised by means of a hydraulic cylinder 6 at the upper end of the column 4. The locomotive-side end of the hydraulic cylinder 8 is attached to the holder 10 in the rear bumper plate of the locomotive and the outer end of the cylinder 8 is attached to the inner holder 12 of the wing. The rear wing 2 is hydraulically set to the desired width or fully retracted. The front wing does not need to be turned during plowing, it is just raised and lowered as needed. A safety valve is connected to the hydraulics of the rear wing, which is triggered if the wing hits a fixed obstacle on the side of the track when plowing. The hydraulics allow the wing to turn freely out of the way of the obstacle.

The locomotive groove according to the invention can be driven in both directions. In Figures I and 2, the "locomotive" itself drives backwards.

In Figures 3 and 4, the position of the plow blades has been changed so that the "locomotive" travels the engine forward and the rollover takes place to the right of the locomotive.

When rolled to the right of the direction of travel, Fig. 4, the wing 2 is turned forward around the column 4. The wing-supporting hydraulic cylinder 8 is now attached to the outer holder 14 of the wing 2. Correspondingly, the wing 1 is now turned to the side wing, the outer end of the hydraulic cylinder 7 being attached to the inner attachment point 11 of the wing 1. wing 2 in front of the wing. The rolling of the snow in relation to the direction of travel of the locomotive takes place to the right.

Two additional mechanical wings 15 and 15 'are mounted on the free side of the locomotive, Fig. 2, whereby when the wings 1 and 2 are in the roll-over position to the left, a narrow walkway 16 can also be plowed, e.g. for shift workers. In the case of Figure 2, the wing 15 'must be turned to the side of the locomotive when plowing, even though it is open in the figure. When plowing, the auxiliary wing on the front wing may be open.

If the yard to be rolled is short, it is appropriate to keep the wings in the same way throughout the roll. You have to start rolling the yard one track at a time and always return to the beginning for the next rolling.

If the tracks in the yard are long, it is advisable to change the wings to the opposite positions after rolling the track and to roll back the next track. Changing the position of the wings is easy and fast in about 1 - 2 minutes.

The line can be plowed in both directions with a rolling plow. The rear wing adjusts the plowing width. If the line to be plowed is double track, the second track is plowed by and the parasite returns.

Figure 6 shows the flow plowing schematically. Snow moves A - B - I) - A '- B' - D '. The rollover here takes place in the direction indicated by the arrows, i.e. from left to right.

The plow blades are on the side of the locomotive during the wagon change so that they do not prevent the locomotive from being connected to the wagon.

Figure 3 shows a front view of the locomotive. The wings turned to the side of the locomotive do not substantially or at all increase the width of the locomotive.

Because changing the position of the wings is so fast, it only takes about 1 to 2 minutes. the various jobs required can be performed in succession as soon as it is necessary.

In the case of the additional mark, the wings of the plow are fitted to the railcar. Of course, they can also be placed on other locomotives, especially locomotives that change wagons, which thus also act as a snow plow.
