DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ballast sweeper for a railway ballast which cleans a ballast laid on a roadbed while traveling on rails.

[0002]

2. Description of the Related Art In general, a railroad track floor is mounted on railroad ties or rails so that railroad vehicles running along rails can run safely and smoothly after squeezing ballasts laid below and around sleepers. Japanese Utility Model Publication No. 56-15207 discloses a sweeper device for cleaning scattered ballasts and cleaning the scattered ballasts on the crossties and rails. There has been proposed a sweeper device in which a body is provided, a rotating brush is provided in the housing, and a flexible skirt is provided on the lower end edge of the housing so as to be in close contact with a rail. This swivel device operates a hydraulic cylinder that suspends the housing to land the rotating brush and skirt, and then sweeps the ballast on the sleeper with the rotating brush inside the housing while running the traveling cart on the rail. In addition, the ballast remaining on the rail is wiped off by a flexible skirt sliding along the rail.

[0003]

In the conventional sweeper device, the ballast on the sleeper is swept down by the rotating brush. However, the ballast swept down by the rotating brush is surrounded by the peripheral wall by the centrifugal force of the rotating brush. There is a risk that the scattered ballast will fall into the case, and the scattered ballast will fall and scatter again on the sleeper. In other words, the purpose is only to clean the ballast scattered on sleepers and rails by the rotating brush and the skirt provided on the lower edge of the housing, since there is no means for collecting the ballast swept by the rotating brush, Even extra ballasts scattered on sleepers and rails remain on the railway track floor, and it is necessary to separately remove such unnecessary ballasts, which is inferior in cleaning workability.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a railway ballast ballast sweeper device capable of reliably removing unnecessary ballast on a railway floor.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, a railroad floor ballast sweeper apparatus according to the present invention scrapes a ballast laid inside a rail on a traveling trolley running on the rail laid on the railroad floor. A rotary sweeper brush is provided, and a conveyor for recovering ballast raked up by the rotary sweeper brush is provided in front of the rotary sweeper brush in parallel with the rotary brush, and the conveyor and the rotary sweeper brush are inclined. A sliding means for sliding the sweeping chute forward and backward, and a tilting means for inclining the sweeping chute forward as the sweeping chute moves away from the rotary sweeper brush in conjunction with the slide; Is provided.

[0006]

In the sweeper device of the present invention, when the traveling vehicle travels, the extra ballast accumulated inside the rail is scraped up by the rotation of the rotary sweeper brush as the traveling vehicle moves, and this ballast is removed by the rotary sweeper brush. It is guided to the conveyor along the slope of the sweep chute interposed between the conveyor and the conveyor. At this time, the sweep chute reciprocates back and forth between the rotary sweeper brush and the conveyor by the slide means, and when the sweep chute moves, the tilting means changes the angle of the sweep chute. By moving the lifting chute toward and away from the rotary sweeper brush, the sweep chute is tilted forward while the sweeping chute and the rotary sweeper brush are farthest apart, and the ballast captured by the rotary sweeper brush is rotated by the rotary sweeper brush. And the swept chute is tilted so that the swept chute rises when it reaches a certain position, and approaches the rotary sweeper brush. By sweeping the brush, it is swept onto the conveyor, such as a sweeping shoe By repeating the back-and-forth movement, it is possible to sweep the positively conveyor was raised scraped by rotation sweeper brush ballast, when the rotating sweeper brush is stopped, it is possible to suppress sweeping leaves also less ballast. Then, the ballast swept out on the conveyor can be discharged to the road shoulder as needed.

The blade 8 is rotated up and down about the shaft 50 by the operation of the cylinder 52. A scraping plate 53 is slidably fitted to the distal ends of both blades 8. The scraping plate 53 is stretched and fixed to the blade 8 with mounting bolts 54 screwed into the upper ends. I have.

The operation of the present invention configured as described above will be described.

First, the mounting frame 13 of the sweeper rotary brush 5 is lowered by the hydraulic cylinder 16, and the lock cylinder 19 is operated to lock the lock hole 17A formed in the lock plate 17 and the lock pin 19A into the receiving hole 18A of the guide plate 18. Insert and lock the mounting frame 13. As a result, the sweeper rotating brush 5 attached to the attachment frame 13 is located between the rails R and grounds on the roadbed A, while the brush 21 is in contact with the sleeper M and the lower part of the rail R. The two blades 8, 8 provided in front of the conveyors 7, 7 are fixed by the mounting bolts 54 after extending the scraping plate 53 provided at the front end thereof, and then the two blades 8, 8 are operated by operating the cylinder 52. Is rotated downward about the shaft 50 so as to protrude to the shoulder A1 of the roadbed A and land on the floor, and the rotating brush 9 attached to the rearmost part of the traveling vehicle 1 is inclined approximately 45 degrees rearward. In this state, the rail R is brought into contact with a fastening portion inside and outside the rail R.

Then, the traveling vehicle 1 is caused to travel on the rail R. With the movement of the traveling carriage 1, the excess ballast B deposited on the road shoulder portion A1 by the blades 8, 8 provided on the front side and the scraping plate 53 provided at the tip end of the blades 8, 8 is removed by the blades. It is raked inward along the inclination of 8, 8 and the rake plate 53. Ballast B and sleepers M
The ballast B scattered on the upper side is swept up by the rotation of the rotary sweeper brush 5 provided on the rear side of the blades 8, 8, and the sweep chute 6 interposed between the rotary sweeper brush 5 and the conveyors 7, 7. Conveyor 7, along the slope
Collected in 7. At this time, the sweep chute 6 is connected to the slide cylinder 31 by the expansion and contraction operation of the slide cylinder 31, and the slide plate 30 is connected to the guide roller 34 that is supported by the slide plate 30 and the guide that is mounted on the mounting shaft 28 of the sweep chute 6. The roller 33 is guided along the guide hole 26A of the guide plate 26, whereby the sweeping chute 6 reciprocates back and forth between the rotary sweeper brush 5 and the conveyors 7, 7; Tilting cylinder 36 when moving
By rotating the link arm 35 fixed to the mounting shaft 28 of the sweep chute 6 by the expansion and contraction operation of the sweep chute 6, the inclination angle of the sweep chute 6 changes. That is, in a state where the sweeping chute 6 is closest to the rotary sweeper brush 5, the inclination angle α of the sweeping chute 6 forms an angle of about 51 degrees as shown by a solid line in FIGS. When the sweep chute 6 is farthest from the rotary sweeper brush 5, the inclination angle α1 of the sweep chute 6 is approximately 41 degrees as shown by the chain line in FIGS. As described above, the sweeping chute 6 rises while moving forward (left side in the figure), conversely moves down while moving the sweeping chute 6 backward (right side in the figure), and moves the sweeping chute 6 from the rotary sweeper brush 5. In the most distant state (indicated by the chain line in FIG. 8), the lower end of the curved plate 25 of the sweeping chute 6 is inclined forward so as to contact the lower part of the rotary sweeper brush 5 so that the rotary sweeper brush 5 The ballast B captured by the rotary sweeper brush 5 accumulates in the gap between the sweep chute 6. Thereafter, the rotary sweeper brush 5 is slid rearward so as to be inclined backward (indicated by a solid line in FIG. 8) so that the curved plate 25 of the sweeping chute 6 comes into close contact with the rotary sweeper brush 5 as a whole. As a result, the ballast B accumulated in the gap between the rotating sweeper brush 5 and the sweeping chute 6
By the rotation of the rotary sweeper brush 5
Can be swept out. That is, the sweep chute 6
The ballast B swept up by the rotary sweeper brush 5 is accumulated to some extent by the sweeping chute 6 by sliding the sweeping chute 6 back and forth while changing the angle of , The ballasts B scattered on the sleepers M inside the rails R can be reliably swept out to the conveyors 7 and 7, and when the rotary sweeper brush 5 accompanying the stop of the traveling vehicle 1 stops, the rotary sweeper brush The ballast B supplemented by 5 accumulates in the gap between the rotary sweeper brush 5 and the sweeping chute 6 and does not enter the roadbed A again, so that the unswept ballast B can be reduced. Even if the sweep chute 6 is moved back and forth, the gap between the sweep chute 6 and the conveyors 7, 7 is closed by the cover 37, so that the ballast B does not spill out from the gap, and the sweep chute does not fall. The ballast B guided by 6 can be reliably sent out to the conveyors 7,7. The ballast B on the conveyors 7, 7 is transferred by the conveyors 7, 7, and the transfer direction of the ballast B can be changed depending on the rotation direction of the conveyors 7, 7. That is, when the ballast B laid on the track bed A inside the rail R is larger than an appropriate amount, when the two conveyors 7, 7 are rotated outward from each other, the ballast B is conveyed in the direction of arrow a in FIG. , 7 are discharged to the outside of the road shoulder A1 from the conveyor chute 44, while the ballast B inside the rail R is smaller than the appropriate amount, the excess accumulated on the road shoulder portion A1 by the two blades 8, 8 described above. The ballasts B and the ballasts B scattered on the sleeper M are collected by the conveyors 7, 7, and the conveyers 7, 7 are rotated in the opposite directions to rotate inward each other. The conveyor R is conveyed in the direction b and falls again from the gap between the two conveyors 7 into the inside of the rail R to be replenished.
Even if the ballasts B replenished inside the spar are scattered on the sleepers M, they can be swept out by the rotary sweeper brush 5. That is, the ballast B collected by the conveyors 7, 7 is selectively changed in the rotation direction of the conveyors 7, 7, so that unnecessary ballasts B are discharged to the roadside A1 outside the rail R, and ballasts inside the rail R are also used. If B is running short, it is also possible to resupply inside the rail R.

The ballast B remaining on the lower part of the rail R and the boundary between the rail R and the sleeper M, which cannot be completely cleaned by the rotary sweeper brush 5, is a brush-like brush attached to the rear end of the mounting frame 13. The ballast B that has been swept out by the rail 21 and remains at the fastening portion of the rail R is
Can be swept out by the rotating brush 9 attached to the rear end of the roller.

As described above, according to the present invention, the ballast B scraped up by the rotary sweeper brush 5 is collected by the conveyors 7, 7, and the ballast B collected by the conveyors 7, 7 is removed from the outside of the rail R if necessary. It can be discharged to the shoulder A1,
Moreover, when the ballast B is picked up by the rotary sweeper brush 5, the sweep chute 6 interposed between the conveyors 7, 7 and the rotary sweeper brush 5 is reciprocated in the front-rear direction by the slide cylinder 31, and the tilt cylinder 36 By moving the sweep chute 6 up and down in conjunction with the forward and backward movement of the sweep chute 6 and repeating such an operation, the ballast B scraped up by the rotary sweeper brush 5 is collected to some extent by the sweep chute 6 and then conveyed. By sweeping 7, 7, sleeper M inside rail R
The ballasts B scattered above can be reliably swept out to the conveyors 7 and 7, and when the rotary sweeper brush 5 stops due to the stop of the traveling vehicle 1, the ballast B supplemented by the rotary sweeper brush 5 becomes a rotary sweeper brush. 5 is collected in the gap between the sweep chute 6 and is not mixed into the roadbed A again, so that the remaining unswept ballast B can be reduced. Further, as an effect of the embodiment, an extra ballast B deposited on the road shoulder portion A1 is once scraped inward by the blades 8 and 8 in an inverted U shape attached to the traveling vehicle 1, and the blades 8 and 8 use the blades 8 and 8 to scrape the ballast B. The conveyed ballast B is transferred to conveyor 7
The transfer direction of the ballast B can be changed depending on the rotation direction of the ballast B. That is, when the ballast B laid on the track bed A inside the rail R is larger than an appropriate amount, the two conveyors 7, 7 are rotated to each other to discharge the ballast B to the outside of the roadside A1, while the rails B are discharged. If the ballast B inside the R is smaller than the proper amount, the conveyors 7, 7 are rotated in the opposite direction to rotate inward each other. The ballasts B collected by the conveyors 7, 7 can be selectively dropped in the direction of rotation of the conveyors 7, 7 so that unnecessary ballasts B can be removed from the road shoulders outside the rail R. A1 and the ballast B inside the rail R
May be re-supplied to the inside of the rail R in the case where is not enough.
