Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trackbed straightening machine that straightens the trackbed of a track.

In general, tracks are constantly being corrected for irregularities in level, height, track, etc., in order to ensure safety for trains, and as the final process of these works, tamping work is performed.
After this tamping work, the trackbed surface is leveled by a trackbed leveling machine.

In this case, in particular, the shoulder width part of the track bed (the part between the longitudinal ends of the sleepers on the top surface of the track bed and the shoulder of the track bed) and the slope part (the sloping part on the side of the track bed) are adjusted and the excess ballast is removed. It is necessary to sweep the trackbed away from the shoulder width area and the slope area and carry it into the areas where ballast is insufficient inside and outside the gauge. Conventionally, in track bed straightening machines that perform this kind of track bed straightening,
Ballast raking boards are installed on both sides of the vehicle and protrude at a certain angle, and while the vehicle is running at low speed, the shoulders and slopes of the roadbed are leveled, and the raked ballast is removed by the vehicle. The ballast was pushed into the duct using the duct, and the ballast was transported into and out of the gauge through the duct.

However, in such a conventional roadbed leveling machine, the ballast scraping plate needs to be made especially strong because it is subjected to large ballast scraping resistance, and also requires the running power of a large vehicle, and furthermore, the entire vehicle It had to have enough weight to not float up due to reaction force, making the whole thing large. In addition, if roadbed adjustment work is performed intermittently at obstacle sections (standard piles, signs, etc.), ballast remains at the interrupted points and the finish becomes poor.
Platy ballast raking boards have the disadvantage of not being able to adequately level the slope of the trackbed. The present invention has been made in consideration of these points, and by adjusting the inside and outside of the track bed, the shoulder width part, and the slope part using rotating brushes, the ballast scraping resistance is reduced, and the ballast scraping resistance is reduced. To provide a track bed leveling machine that can smoothly carry cleaned ballast into and out of a gauge. Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the road bed leveling machine according to the present invention has support rods provided on both sides of a vehicle 1 so as to be movable in the vertical direction by hydraulic cylinders 2 for vertical movement. 3, a first support frame 5 rotatably attached to the support rod 3, and a first rotating brush 4 rotatably attached to the first support frame 5 for leveling the ballast at the shoulder width portion of the trackbed. , is attached to the tip of the first support frame 5 via a connecting pin 15, can be rolled up and down around the connecting pin 15, and can be rotated around the support rod 3 via the first support frame 5. It is connected to the second rotary support frame 7 and the first rotary brush 4 via a universal joint (not shown), and is attached to the second support frame 7 so as to be rotatable in the same direction as the first rotary brush 4.
The second rotating brush 6 is capable of leveling the ballast on the slope of the trackbed, and the first support frame 5 is rotated outward around the support rod 3, and the first support frame 5 is rotated at a predetermined angle position. A lock bar 13 is attached to the first support frame 5 on the cylinder side and to the second support frame 7 on the piston shaft side, and is attached to a lock bar 13 that rotates the second support frame 7 in the vertical direction around the connecting pin 15. A rotating hydraulic cylinder 9, a drive mechanism section 8 provided on the first support frame 5 and having a power source for driving the first rotating brush 4 and the second rotating brush 6, and a vehicle capable of vertically moving across the rails 10. The first support frame 5 and the second support frame 7 are pulled up to within the vehicle limit by the vertical movement hydraulic cylinder 2 during forwarding, and wires 14 are used to fix them in that position. has been done.

The vertical movement hydraulic cylinder 2, the vertical movement hydraulic cylinder 9, and the drive mechanism section 8 are driven by operating each operating lever of an operating lever device 12 provided on the driver's cab of the vehicle 1. Next, the operation of the roadbed straightening machine of the present invention configured as described above will be explained.

When leveling the track bed, the first support frame 5 and the second support frame 7 are slightly lifted by the hydraulic cylinder 2 for vertical movement, and the wire 14 is
As shown on the right side of FIG. The two-rotation brush 6 is lowered, and the first support frame 5 is placed around the support rod 3.
Then, the second support frame 7 is rotated outward so that the rotation axes of the first rotating brush 4 and the second rotating brush 6 are set at a predetermined angle (usually within the range of 30° to 60°) with respect to the traveling direction of the vehicle 1. ), the first rotating brush 4 is positioned on the ballast at the shoulder width part of the track bed, and then the vertical movement hydraulic cylinder 9
As a result, the second support frame 7 is rotated downward, and the second rotating brush 6 is positioned on the ballast of the slope part of the track bed (normally, the slope is about 30 degrees).

Thereafter, the drive mechanism section 8 rotates the first rotating brush 4 and the second rotating brush 6 while moving the first rotating brush 4 and the second rotating brush 6 along the rails of the vehicle 1. , the track bed can be straightened continuously.
At this time, the first and second rotating brushes 4 and 6 rotate in the directions shown by the arrows in FIG. Next, the first rotating brush 4 levels the shoulder width part of the trackbed and scrapes excess ballast into the track via the scraping plate 11. In addition, in the roadbed leveling machine according to the present invention, as described above, the height and angle of the first and second rotating brushes 4 and 6 can be adjusted, so if each setting is adjusted appropriately, the amount of ballast scraping or The amount carried into and out of the track can be changed, and not only the shoulder width portion and slope portion of the track bed can be leveled, but also their correction can be arbitrarily performed. Furthermore, by changing the rotational speed of the first and second rotating brushes 4 and 6, the remaining amount of ballast and the amount of carried-in can be adjusted. The brushes of the first and second rotating brushes 4 and 6 may be arranged concentrically, but if they are arranged spirally, the ballast can be carried in more efficiently and without resistance. It will be possible.
At the time of forwarding, the piston shaft of the hydraulic cylinder 9 for vertical movement is retracted to raise the second support frame 7, and the connected first
The first support frame 5 is rotated so that the support frame 5 and the second support frame 7 face forward of the vehicle 1, and then the hydraulic cylinder 2 for vertical movement is driven as shown on the left side in FIG. 1st
The wire 14 is pulled up so that the support frame 5 and the second support frame 7 do not interfere with the running of the vehicle 1 and are within the limits of the vehicle.
Fix it by.

As described above, in the trackbed leveling machine according to the present invention, since the shoulder width part and the slope part of the trackbed are leveled using rotating brushes, the trackbed can be leveled unevenly. Ballast is carried between the rails by the rotation of rotating brushes without depending on the running of the vehicle, so even if there are obstacles such as reference piles on curved sections of the track and intermittent work is carried out. There is no excess ballast left in the area during the work, and a good finish can always be obtained no matter what the work situation is.

In addition, in the present invention, since a rotating brush is used in particular to scrape up the ballast and carry it between the rails, the resistance received from the roadbed during work is extremely small, which reduces the running power and weight of the vehicle. This makes the entire vehicle smaller and lighter. Furthermore, the trackbed leveling machine according to the present invention has the advantage that the setting position of each rotating brush can be adjusted, and the leveling state of the trackbed can be arbitrarily changed by adjusting the rotation speed of the rotating brushes. have. In addition, the track bed leveling machine according to the present invention is used not only to level the shoulder width part and slope part of the track bed as described above, but also to level the track bed part between the tracks in the case of double track. can do.

In this case, as long as the support frame 7 of the second rotating brush 6 is held horizontally without tilting downward as described above, the rest is done in the same manner as described above to collect the ballast and move it between the rails. can be carried in.
