ため大きさに限界がある。The ballasting and filling work in ballast exchange requires high-speed and high-efficiency work because it must be performed within a short period of time, avoiding the running time of the train. It is not an exaggeration to say that the work is governed by the performance of the scraping chain because it is greatly influenced by the performance of the scraping device, particularly the wear resistance and the scraping ability of the chain.
To improve ballast scraping performance, it is effective to increase the effective width (height) of the scraping claws (bits) fixed to the chain. However, in the conventional chain type chain, the effective width of the scraping claws is reduced. If it is increased, the rotation of the chain becomes unstable, and there is a disadvantage that the life is shortened due to uneven wear with the guide mechanism. Furthermore, the scraping chain must be able to smoothly bend and travel even at a curved portion between the horizontal portion inserted into the roadbed and the unloading conveyor. In addition, the scraping device mounted on the work vehicle is held in parallel with the rail on one side of the work vehicle during traveling and has to work even in a tunnel, so there is a limit in size.

Denotes a top plate, and 24 denotes a ballast push-out wall suspended from the top plate, and a scraping claw 26 protrudes from the inclined end 25.
The scraping nail is replaceably provided by a known rotating bit. Reference numerals 27 and 28 denote a pair of legs connected to the lower surface of the upper plate 23, and flanges 29 and 29 are provided at lower ends thereof. An arc surface 31 is formed on the outer surface of one leg piece 27 according to the curvature of a chain curved portion described later. 3
Reference numeral 2 denotes a tapered surface formed at a corner of the upper surface plate 23 including the leg pieces 27 and 28, which forms a large arc by connecting the arc surfaces 31 of the link members in the curved portion of the chain body. Ensures smooth running.
