【発明が解決しようとする課題】前者の整形機械である
と車体をある程度の車速以上で走行させる必要があり危
険である。つまり、前者の整形機械を高速で走行すると
ブレードに大きな負荷が作用し車体が軌道から外れたり
することがあって大変危険である。With the former shaping machine, it is necessary to run the vehicle at a certain speed or higher, which is dangerous. In other words, when the former shaping machine is run at a high speed, a large load acts on the blades, and the vehicle body may go off the track, which is very dangerous.

要があるし、掻き上げ爪による掻き上げのみでは整形精
度が悪い。[0005] With the latter shaping machine, crushed stones can be scraped up even when the vehicle body is stopped, but since the scraping claws dig directly into the slope, it is necessary to rotate the endless chain with a large driving force. Shaping accuracy is poor only by raising with a raised nail.

By running the vehicle body 10 along the rails 5, the crushed stone on the slope 3 of the track bed 1 is firstly scraped by the scraping device A to rough the slope 3, whereby the crushed stone is scraped to the upper surface 2 of the track bed 1. It is raised and rises on the upper surface 8 between the sleepers and the upper surface 7 on the side. Next, the crushed stone swelling on the upper surface 8 between the sleepers is
1 and the excess crushed stone flows to the side upper surface 7, and the crushed stone on the side upper surface 7 is leveled by the third blade 79 to correctly shape the shoulder 6 and to remove the excess crushed stone on the slope. Pour into 3. Finally, the slope 3 is finished and shaped by the slope shaping blade B. During the shaping operation, the crushed stones
Riding on the top is prevented by the rail cover C. In addition, since each shaping operation portion described above can be visually observed by an operator in the cab 12, each shaping operation can be visually observed and each part can be operation-controlled, so that a single operator can perform a roadbed shaping operation.

7 to rotate the endless chain 45 to break the slope 3
The stone is scraped off on the slope of the projection 42a of the lower skirt 42.
6 and the quarry is made with an endless chain 45
Along the slope 3 with the scraper 46 that moves together to the upper surface 2
I can be scraped up. Therefore, the slope 3 can be shaped even when the vehicle body 10 runs at a low speed. Since the scraper 46 does not bite into the slope 3 directly, the driving force of the endless chain 45 can be reduced. By extending and contracting the tilting cylinder 28 and the lifting / lowering cylinder 32, the attachment body 16 is tilted up and down in the vertical direction.
Since the frame 40 swings in the horizontal plane direction by expanding and contracting the swing cylinder 56, the scraping device A can be tilted up and down with respect to the vehicle body 10, raised and lowered, and swung in the horizontal plane direction. The finishing width can be adjusted, and the scraping device A can be stored in parallel with the vehicle body 10. Scooping device A
With the first blade 71 and the third blade 79, the crushed stone that has been scraped up and raised on the upper surface 2 of the roadbed 1 can be shaped. Crushed stones can be prevented from riding on the rails 5 when shaping the upper surface 2 and the slope 3 of the roadbed 1. The rail cover C and the first and third blades 71 and 79 are connected to one vertical cylinder 6.
2 to move it up and out of the way when not working. The scraping device A and the slope shaping blade B can be stored in parallel in the narrow front end of the vehicle body, so that the vehicle can be kept within the vehicle width limit during non-working time. The operator can perform shaping work.
