Description

G3 U! I,: 'I' \ | ¿\ 1 _> ._ :. Figure 2 shows a locomotive according to the present invention seen from the front when the plow wings are in side position, i.e. in gear working position.

Figure 6 shows the snow plowing schematically. A - B - C - D / A '- B' - C'- D '.

The invention is characterized in that the locomotive snow plow immediately, if necessary, functions as a locomotive or a gear locomotive, the buffers and couplings being visible at both ends and ready for use, and that the locomotive snow plow in a snow area can immediately function as a snow plow in both directions or as a rollover plow. of snow over adjacent tracks.

The invention is based on the fact that at both ends of the locomotive, on a post at the corner of the locomotive, a plow wing is stored, which can be raised or lowered and swung next to the locomotive side and also swiveled in different plowing positions.

Figures 1 and 2 show the position of the plow wing 1 at the rear (T) of the locomotive and the position of the plow wing 2 at the front (E) of the locomotive when plowing backwards with the locomotive and plowing the snow in the direction of travel seen to the left.

In figure 2, the plow wing 1 in the rear end (T) of the locomotive is curved in the plowing direction seen to the front wing and the wing 2 in the front end (E) of the locomotive to the rear wing.

The front wing 1 is mounted on the post 3 which is located at the right corner of the rear end of the locomotive. With the hydraulic cylinder 5, the wing 1 is lifted up from the side of the locomotive and swung into the plowing position. Figure 2 shows how the outer end of the hydraulic cylinder 7 fastened to the buffer plate holder 9 is fastened to the outer holder 13 of the wing 1.

The plow wing 2 is lifted up by means of the hydraulic cylinder 6 in the upper end of post 4. One end of the hydraulic cylinder 8 is attached to the holder 10 on the front buffer plate and the other end, the outer end, is attached to the inner holder 12 of the wing. as front wing and wing 2 as rear wing.

The rear wing 2 is hydraulically adjusted to the desired width or fully retracted. The front wing does not need to be swung during plowing, it is only raised or lowered as needed. A safety valve is connected to the rear wing hydraulics, which releases if the wing strikes a fixed obstacle at the side of the track during plowing.

The hydraulics now allow the wing to swing freely away from the obstacle. A locomotive plow according to the present invention can be driven in both directions. In Figures 1 and 2, the "locomotive" itself drives backwards.

In Figures 3 and 4, the position of the wings of the plow is changed so that "the locomotive itself" moves forward (E) and the "rollover plowing" takes place to the right side of the locomotive. When "rollover plows" to the right, seen in the direction of travel, figure 4, the wing 2 turned around the post 4 to the front wing. The hydraulic cylinder 8 supporting the wing is now fixed in the outer holder 14 of the wing 2. Correspondingly, the wing 1 is now pivoted to the rear wing, the outer end of the hydraulic cylinder 7 being fixed in the inner holder 11 of the wing 1.

Now the wings 1 and 2 have only changed function, the wing 1 has become a side wing and the wing 2 a front wing. The snow's "rollover plowing" in the direction of the locomotive takes place to the right.

On the free side of the locomotive, two additional mechanical wings 15 and 15 'are mounted, figure 2, whereby when the wings 1 and 2 are in the "roll ring plowing" position, a narrow walkway 16 can also be plowed, e.g. for shift workers.

If the yard to be "rollover plowed" is short, it is expedient to keep the wings in the same position during the entire "rollover plowing". You "roll over" the yard one track at a time and always return to the same end of the yard each time.

If the tracks of the railway yard are long, it pays to change the position of the wings to the opposite and "roll-plow" following tracks when driving back. Changing the position of the wings is easy and fast, it takes about 1-2 minutes.

With the rollover plow, you can plow the line in both directions. With the rear wing, the plowing width is adjusted. If the line to be plowed is two-track, one track is plowed then. You drive in one direction and the other when you drive back.

Figure 6 shows rollover plowing schematically. The snow is moved A - B - D - A '- B' - D '. The rollover plowing takes place here in the direction of the arrows, ie from left to right.

The wings of the plow are during the time the locomotive is performing shift work in the recessed position along the side of the locomotive so that they do not prevent the locomotive from connecting to the carriages.

Figure 5 shows a locomotive seen from the front. The wings, which are in an inward-facing position on the side of the locomotive, do not increase significantly or at all the width of the locomotive.

Since the wings can be adjusted so quickly, in just 1-2 minutes, you can perform various necessary tasks one after the other as soon as the situation requires it.

In the example given, the plow's wings are adapted on a trolley. They can of course also be mounted on other locomotives, but especially on locomotives that perform shift work and thus at the same time function as a snow plow.

Claims (1)

1.. | "'{~" -ï "PATENT REQUIREMENTS In Locomotive plow, line plow, yard plow or rollover plow and line locomotive or gear locomotive, whose buffers are visible and can be used for shift work, the locomotive plow consisting of plow wings which in the gear working position pivot parallel to the side of the locomotive they are located in the profile of the moving material, characterized in that at both ends of the locomotive, near the corner of the frame, at upright posts (3, 4) pivot wings (1, 2) which can be pivoted to plowing position are pivotally stored so that the wings can serve either as the front wing or side wing of the snow plow, because the wings are pivoted parallel to the longitudinal direction of the locomotive, when the snow plow locomotive performs shift work. The locomotive snow plow according to claim 1, characterized in that the plow wings (1, 2) have been stored at posts (3, 4) at the upper ends of which hydraulic cylinders (5, 6) are arranged for lifting and lowering the wings. Locomotive snow plow according to patent wings (1, 2) are supported against the middle part (9, 10) of the locomotive's buffer beams by means of hydraulic cylinders (7, 8) so that the attachment points on the wings are closer (11, 12) or further out (13) 14) depending on , if the wing serves as a side or front wing. Locomotive snow plow according to claims 1, 2 or 3, characterized in that the plowing width can be adjusted with the hydraulic cylinders (7, 8) attached to the side wings.
