JPS58167001A - Reconditioning device of old rail - Google Patents

Abstract

PURPOSE:To provide a titled device which can roll and recondition an old rail easily to a rail or I-beam of the same material by providing rolls for rolling the top and bottom surfaces of the rail and rolls for rolling both side surfaces thereof on one rolling line. CONSTITUTION:An old used roll 2 of about 50-60kg/m is heated red hot and the top and bottom surfaces 2', 2'' as well as side surfaces 2''' thereof are rolled by using a reconditioning device for old rails of the constitution wherein rolls 3, 3' (only the 3' is shown) for rolling the top and bottom surfaces of the rail are provided in the beginning end part of a machine frame 1, plural sets of rolls 4, 4' for rolling both side surfaces of the rail are juxtaposed on the same rolling line L as said rolling line, and the rolls are driven respectively independently by prime movers 6 via sprockets 7, 8, chains 9, driving shafts 10, etc. The number of revolutions of the machine 6 is increased successively from the beginning end part toward the final end part, whereby the rail 2 is extended longitudinally and a reconditioned rail or I-beam 11 of about 30kg/m weight is obtained.

Currently, a large amount of heavy old rails are generated due to rail replacement carried out by Japanese National Railways and private railways. However, most of it is discarded as melting strips and ramps. Using special steel materials such as rails as raw material for melting is wasteful from the viewpoint of the company, and by recycling and recycling, rails or I-beams made of the same material can be easily made without melting and refining. It is intended to be manufactured into leather.

。To explain the embodiment of the present invention shown in the drawings, as shown in FIG.
Only rolling rolls 3 and 3' of ' and f are provided;
' Subsequently, on one rolling line L, a plurality of sets (four sets) of rolling rolls 4, 4' on both sides of the rail 2 are arranged in parallel, and each set of rolling rolls 3, 3', 4, 4 ’ is connected to the floating shaft 5.
The other support shaft is a drive shaft 10, and the plurality of prime movers 6 provided on the machine frame 1 and the drive shaft 10 are connected to a spulkerato 7,
8 and a chain 9, and the drive rotational speed of the prime mover 6 is increased sequentially from the starting end of the line L toward the terminal end, thereby making it possible to adapt to changes in the moving speed due to rolling of the red-hot rail 2. The upper and lower surface rolling rolls 3 and 7 are rolled to the height of the final rolling strip rail 11 (see Figure 6), and the rolling rolls 4.4' of each set are approximately at the height of the rail as shown in Figure 2. It may have a cross-sectional shape, or it may have a cross-sectional shape of a shaped steel as shown in FIG. Then, each set of rolling is performed by sequentially rolling only both sides of the rail so that the final rolled shape is as shown by the solid line in Fig. 6, or the unit weight is almost the same as that of the rail 11 shown in Fig. 6. It may be made of steel (pukar). In the figure, 12 indicates a heating furnace, and 13 indicates a straightening roll for finally correcting the distortion 9 and the like.

ことかできる。Therefore, the fine copy rail 2 (60 to 5
o9') is inserted into the heating furnace 12 to become red hot so that it can be deformed, and when it is inserted from the starting end into multiple sets of rolling rolls 3.3' and 4.4' on one rolling line L, it is driven. p
- The red-hot rail 2 is moved along one rolling line L by the rotational force of the rolling wheels 3' and 4', and the deformed red-hot old rail 2 shown by the solid line in Figure 8 is moved along the rolling line L by each set of rolling wheels. One rolling line L includes a rail that is rolled vertically and horizontally into the cross-sectional shape shown and extends in the longitudinal direction, and has a unit length of 1A9 and a weight of about 30.
It is possible to manufacture recycled rails by rolling and forming the rails simply by passing them through the rails.

のである。Conventional rail rolling equipment has been applied to the rolling regeneration of used rails, and there have been rolling defects, but since the present invention is configured as described above, it is possible to roll rice with a paper weight of 60ζ to 50, which has little utility value - the rumored used product. There is an effect that recycled rails 11 or bokars with a small arbor per rice and high utility value can be manufactured very easily from old rails 10 by one rolling line L. In other words, although the length of the cleaning rail 2 used is relatively short, it is heated in a heating furnace 12 and placed in the above-mentioned one rolling line L provided in one machine frame 1). Since it is successively pinched, pulled and rolled from the tip by the plurality of rolling rolls that are driven by the above-mentioned system, a relatively short used fine writing rail 2 can be quickly and smoothly regenerated into a rail with a unit length and a small weight. be.
