[0002]

2. Description of the Related Art In the maintenance work of a railway, a large vehicle called a multiple tie tamper is used to correct the track of a rail, and then a rough ballast (paving stone) scattered on sleepers is arranged. For this reason, ballasts inside and outside the rails were sorted out using a sorter called a ballast sweeper. In addition, as shown in FIG. 9, ballasts c... Remaining on the rail portion (the range M from the rail a to the fastening fittings b, b) have conventionally been removed by a manual operation using a broom or the like.

[0003]

However, since the ballast removal work after the ballast arrangement work has been performed by mechanization, the work efficiency is poor because it is ultimately a human work, and the mechanization of the work has been desired.

Accordingly, an object of the present invention is to provide a rail part ballast removing apparatus which eliminates human work by mechanization and improves work efficiency.

The intermediate plate portion 23 of the link mechanism E is drawn forward, and the first and second frame members 14 and 15 are
Swings left and right about the pivot shafts 17, 17. Then, the first frame 14 inclines to the inside of the rail 5, and the second frame 15 inclines to the outside of the rail 5. At this time, the connecting rods 22, 22 move three-dimensionally in the left-right direction and the up-down direction at the spherical joints 24, and the tip of the actuator 16 swings up-down in the pivoting member 21. The first and second frames 14, 15 can be smoothly swung.

The first rotating brush 2 is driven by the first swing mechanism A.
The first shaft 2a (having a substantially horizontal axis in the width direction) is rocked and inclined so that the lower end edge of the first rotating brush 2 approaches the corner 5a inside the rail 5. Further, the second swinging mechanism B causes the second rotating brush 3 to move to the second position (along the horizontal axis).
The shaft 3a is swung to be inclined so that the lower end edge of the second rotating brush 3 approaches the corner 5a outside the rail 5.
At this time, the angles θ ₁ and θ ₂ of the rod-shaped elastic bodies 4 and 4 of the first and second rotary brushes 2 and 3 with respect to the rail 5 are about 20 respectively.
° is set. The first and second rotating brushes 2,
The lower end edge of 3 is the tip end surface 4a of the rod-shaped elastic body 4 located below.

Now, the use state of the rail portion ballast removing device of the present invention will be described. As shown in FIGS. 3 and 4B, the first and second swing mechanisms A and B (as described above) are used. , The first and second rotating brushes 2 and 3 are inclined, and the first and second rotating brushes 2 and 3 are inclined in a direction (ie, a rotating direction D opposite to the rotation of the wheels 25) opposite to the traveling direction C of the truck 1. The rotating brushes 2 and 3 are rotated.

Then, the first rotation orbit 27 indicated by the two-dot chain line
The tip ends of the rod-like elastic members 4 of the second rotating brushes 2 and 3 rotate, and the rod-like elastic members 4 located in the lower region 30 of the rotation track 27 ride on the corners 5a and 5a inside and outside the rail 5. The ballast 26 ... is jumped up and removed one after another. Since the ballasts 26 are flipped forward, even if the ballasts 26 jumped on the corners 5a are removed again, the ballasts 26 at the processed rear corners 5a are surely removed. Also,
By setting the angles θ ₁ and θ ₂ (described above) to about 20 °, the efficiency of removing the ballasts 26 can be increased and the resistance load on the rail 5 can be reduced.

As shown in FIGS. 2, 6 and 7, simultaneously with the rotation of the first and second rotating brushes 2 and 3, the third and fourth rotating brushes 2 and 3 are rotated.
The rotating brushes 6 and 7 are also rotated. Third rotating brush 6
The tip of the rod-shaped elastic body 4 is a rotating orbit 28 indicated by a two-dot chain line, and the rod-shaped elastic body 4 located in the lower region 31 of the rotating orbit 28 rotates in the direction toward the inside of the rail 5. ing.

The ballast rides on the bottom 5c inside the rail 5 (connecting the rail 5 and the sleeper 33) and the fastening fitting 18 (including the fastening bolt 19) by the rotation of the rod-shaped elastic bodies 4.
26 are flipped up to the inside of the rail 5 and are sequentially removed.
At this time, the rod-shaped elastic bodies 4
Overcoming by elastic deformation, and the lower area of the rotary orbit 28
Ballast 26 while contacting fastening metal 18 and fastening bolt 19 with 31 ...
Is removed.

The fourth rotating brush 7 has the rod-like elastic members 4.
The tip of the rod-shaped elastic body 4 located in the lower region 32 of the rotation orbit 29 is a rail 5
Is rotating in the direction toward the outside. This rod-shaped elastic body 4
By the rotation of the ballasts 26 on the bottom 5c outside the rail 5 and the fasteners 18 (including the fasteners 19),
It is flipped up to the outside of the rail 5 and sequentially removed. Also in this case, the rod-like elastic bodies 4 get over the head 5b of the rail 5 by elastically deforming, and remove the ballasts 26 while being in contact with the fastening fittings 18 and the fastening bolts 19 in the lower region 32 of the rotating track 28. .

As shown in FIG. 8, the ballast removing device of the present invention has the ballast removing portions G, G corresponding to the pair of rails 5, 5, respectively, attached to the bogie 1 so that the rails 5, 5 are provided. Ballast automatically while traveling along
26 ... can be eliminated.

As means for moving the carriage 1, there are:
For example, a drive motor may be attached to a large truck K to which the truck 1 is attached, and the rails 5 and 5 may be automatically run. Alternatively, the truck 1 may be omitted (with the truck K omitted). May be connected to a ballast arranging machine called a ballast sweeper or a vehicle for various track maintenance so as to be able to move up and down, and may be stored in the vehicle except during processing.

The present invention is not limited to the above-described embodiment. For example, the first and second rotating brushes 2 and 3 provided in a slanted shape can be provided along the guide rail provided in the carriage 1 in the width direction F. And slide in the width direction F to make corners 5a, 5
A configuration may be adopted in which the lower end edges of the first and second rotating brushes 2 and 3 are brought closer to a.

[0032]

Since the present invention is configured as described above, the following effects can be obtained.

(According to claim 1 ) A pair of rails 5,5
At this time, the operation of removing the inner corner 5a of the rail 5 and the ballast 26 riding on the fastener 18 and the outer corner 5a, the bottom 5c of the rail 5 and the ballast 26 riding on the fastener 18 are performed. Since the operation is mechanized and the human work is omitted, the work efficiency is improved, and the number of workers can be reduced. Rails 5, 5
, The ballast 26 is sequentially removed, so that an unprocessed portion (a portion that is not removed) of the ballast 26 is not formed.

[0034] According to the second aspect , before the start of swinging, the first
Since the rod-like elastic members 4 and 4 below the second rotating brushes 2 and 3 are in a vertical state, the carriage 1 is not hooked on the head 5b of the rail 5 and the carriage 1 is attached to the rails 5 and 5. Can be mounted. Further, the first and second swing mechanisms A and B
The first and second rotating brushes 2,
3 avoids the head 5b of the rail 5 at the corner 5
a, 5a, so that the ballasts 26 at the corners 5a, 5a can be effectively removed.

[0035] (According to claim 3) can be swung both the first and second rotating brushes 2 and 3 one actuator 16, the structure is simple.
