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 swivel device for cleaning ballast scattered on the railroad ties 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 ballast scattered in the housing that has fallen, resulting in the scattered ballast falling and scattered again on the sleepers, not only cannot effectively clean the ballast remaining on the sleepers, but also the ballasts on the rails are simply Press the skirt provided on the lower edge of the housing against the rail,
Since only the ballast is wiped off by the movement of the traveling cart, the ballast around the bolt for fastening the rail remains. In other words, the bolts that fasten the rails have their heads protruding above the rails, so the skirt is turned up along the bolts and the ballast around the bolts cannot be reliably removed. When retightening the bolts to be fastened, it is necessary to remove the ballast remaining around the bolts, which is inferior in track maintenance workability.

In addition, it is important to lay ballast on a railway track floor uniformly and without excess or deficiency in terms of buffering action of the entire rail, preventing movement of sleepers, and improving drainage. The sweeper device is intended only for cleaning ballasts scattered on sleepers and rails simply by a rotating brush and a skirt provided at the lower edge of the housing, and there is no means for collecting ballast swept by the rotating brush. Therefore, in the conventional sweeper device, even the excess ballast scattered on the sleepers and rails remains on the railway track floor, and it is necessary to remove such unnecessary ballast, and conversely, the ballast amount is insufficient. In such a case, it is impossible to fill unnecessary parts with unnecessary ballast, and such repair work on the railway track floor has to be performed separately from cleaning work.

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem, and it is possible to reliably clean unnecessary ballasts on a railway track floor and to perform repair work on the railway track floor simultaneously with ballast cleaning work. An object of the present invention is to provide a sweeper device for a railway ballast ballast.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a railroad track ballast sweeper apparatus in which a ballast laid on a road shoulder portion of a railroad track is swept inward by a traveling vehicle running on a rail. A C-shaped blade is attached, and a rotating sweeper brush is provided on the rear side of the blade to scrape up the ballast raked by the blade,
At the front side of the rotary sweeper brush, the ballast scraped up by the rotary sweeper brush is collected in parallel with the rotary brush, and the ballast is selectively discharged to the inside of the rail or to the shoulder of the railroad track floor. A pair of left and right conveyors that are rotatable forward and backward are separated from each other at the left and right sides, and between the left and right conveyors and the rotary sweeper brush, the lower side is close to the rotary sweeper brush, and the upper end is the pair of left and right. An inclined sweeping chute is provided to guide the ballast wrapped around the inner edge of the conveyor with the rotary sweeper brush to the left and right conveyors, and a sliding means for sliding the sweeping chute back and forth and the sweeping means. The sweep chute is tilted forward as it moves away from the rotary sweeper brush in conjunction with the slide of the lift chute. The motion means is provided, and the rearward rotational Suipaburashi are those provided swiveling freely rotating brush in contact with an inclination to the fastening portion of the rail and outside.

[0007]

In the sweeper device for a ballast on a railway track floor according to the present invention, when the traveling vehicle travels, the traveling vehicle moves along with the traveling vehicle.
Excess ballast accumulated on the road shoulder by the blade is swept inward along the inclination of the blade. The swept ballast and ballast scattered on the crossties are swept up by the rotation of the rotary sweeper brush provided on the rear side of both blades, and follow the inclination of the sweep chute interposed between the rotary sweeper brush and the conveyor. Guide to the conveyor. At this time, the sweeping chute reciprocates back and forth between the rotary sweeper brush and the conveyor by the sliding means, and changes the angle of the sweeping chute by the tilting means during the movement of the sweeping chute. By moving the lifting chute toward and away from the rotary sweeper brush, the ballast caught by the rotary sweeper brush in a state where the sweeping chute and the conveyor are farthest apart is collected in the gap between the rotary sweeper brush and the sweeping chute, and is collected to some extent By inclining the sweeping chute to the rotating sweeper brush backward so as to make close contact with the rotating sweeper brush at a stage, the ballast accumulated in the gap between the rotating sweeper brush and the sweeping chute is swept out to the conveyor by rotation of the rotating sweeper brush. By rotating the sweep chute back and forth, the rotary sweeper Together it was raised scraped ballast can be reliably swept out to the conveyor by brush, when rotating sweeper brush is stopped, it is possible to suppress sweeping leaves also less ballast. Then, the ballast swept out onto the conveyor is transferred by the conveyor, and by selectively changing the rotation direction of the conveyor, when the ballast laid on the track inside the rail is more than an appropriate amount, If the conveyors are rotated outward from each other, the ballast on both conveyors will be discharged to the road shoulder, while if the ballast is less than the proper amount, the above-mentioned blades will cause the ballast on the sleeper, including the extra ballast deposited on the road shoulder. The ballast can be replenished to the inside of the rail from the gap between the two conveyors by rotating the conveyors inside each other. Finally, the ballast remaining on the fastening portion of the rail is swept out with a rotating brush, but the rotating brush is inclined to the rail so that the ballast is not involved due to the rotation of the rotating brush. Only the ballast scattered at the joint of the rail is swept out of the rail without surrounding ballast gathering at the joint.

Further, an arm 67 is integrally fixed to substantially the center of the horizontal shaft 65, and a cylinder 66 for swinging the rotating brushes 9, 9 is connected to the arm 67. Further, a lock arm 68 is fixed to the horizontal shaft 65 adjacent to the arm 67, and a lock pin 69A of an air cylinder 69 is fitted into a lock hole 68A formed in the lock arm 68 to thereby rotate the rotary brush. It is configured to lock 9, 9 in a horizontal position.

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

First, the mounting frame 13 of the sweeper rotating 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 pivoted downward about the axis 50 so that the scraping plate 53 extends to the shoulder A1 of the roadbed A and is landed.
After the rotating brush 9 attached to the rearmost part of the rail R is contacted with the fastening portion R1 inside and outside the rail R in a state where the rotating brush 9 is inclined approximately 45 degrees rearward by the cylinder 66, the air cylinder 69 for locking is operated to lock the pin 69A. Is inserted into a lock hole 68A formed in the lock arm 68 to fix the rotating brush 9.

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 a chain line in FIG. 8), the lower end of the curved plate 25 of the sweeping chute 6 is inclined forward so as to be in contact with the outer end of the rotary sweeper brush 5, and The ballast B captured by the rotary sweeper brush 5 accumulates in the gap between the sweep chute 6. After this,
The rotary sweeper brush 5 is slid rearward so that the curved plate 25 of the sweeping chute 6 is tilted backward (shown by a solid line in FIG. 8) so as to be in close contact with the rotary sweeper brush 5, so that the rotary sweeper brush 5 is rotated. The ballast B accumulated in the gap between the brush 5 and the sweeping chute 6 is rotated by a rotary sweeper brush 5.
Can be swept out to the conveyors 7, 7 by the rotation of. That is, while changing the angle of the sweep chute 6,
By sliding the sweeping chute 6 back and forth, and repeating such an operation, the ballast B scraped up by the rotary sweeper brush 5 is collected to a certain extent by the sweeping chute 6 and then the conveyors 7 and 7 are swept out to obtain a rail. The ballasts B scattered on the sleeper M inside the R can be reliably swept out to the conveyors 7 and 7, and when the rotary sweeper brush 5 is stopped, the unswept ballasts 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. Then, the ballast B on the conveyors 7, 7 is transferred by the conveyors 7, 7,
The transfer direction of the ballast B can be changed according to 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, when the two conveyors 7, 7 are rotated outward from each other, the ballast B is conveyed in the direction of arrow a shown in FIG. When the ballast B inside the rail R is smaller than an appropriate amount, the dust is discharged from the conveyor chute 44 at the outer end portion of the road 7 to the outside of the road shoulder A1. The extra ballasts B and the ballasts B scattered on the sleepers M are collected by the conveyors 7, 7, and the conveyers 7, 7 are rotated in the opposite directions to rotate inward each other. It is conveyed in the direction of the arrow b shown in the figure, and can be distributed right and left by the inverted V-shaped distribution plate 45 from the gap between the two conveyors 7 and 7 and fall again inside the rail R to be replenished. Of R Even if the ballast B replenished on the side is scattered on the sleeper M, it can be swept out by the rotary sweeper brush 5. That is, by changing the rotation direction of the conveyors 7 and 7 to the ballast B collected by the conveyors 7 and 7, the ballast B in the rail R is changed.
Can be selectively distributed to the inside of the rail R or to the roadside A1 according to the laying condition of the vehicle.

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 21 and remains at the fastening portion R1 of the rail R can be swept out by the rotating brush 9 attached to the rearmost portion of the traveling vehicle 1, and in particular, the rotating brush that cleans the fastening portion R1 that is difficult to sweep out. As shown in FIG. 12, as shown in FIG. 12, by being inclined approximately 45 degrees with respect to the rail R and being brought into contact with the inside and outside of the rail R, it can be reliably swept out. That is,
When the rotating brush 9 is rotated in contact with the rail R so as to be perpendicular to the rail R, the ballast B scattered around the fastening portion R1 is swept out, but the ballast B deposited on the periphery of the fastening portion R1 is also involved. There is a risk that the ballast B may remain in the fastening portion R1. However, by rotating the rotating brush 9 at an angle of 45 degrees with respect to the rail R, only one end of the rotating brush 9 contacts the fastening portion R1, The other end floats from the periphery of the fastening portion R1 and is rotated by the rotating brush 9 to fasten the fastening portion R1.
Since the ballast B at the peripheral portion of the joint portion is not involved, only the ballast B at the fastening portion R1 can be effectively swept out.

As described above, according to the present invention, the ballast B laid on the shoulder A1 of the railroad floor A is raked inwardly by the blades 8, 8 attached to the traveling vehicle 1 and the blades 8, 8 are used. , 8 is provided with a rotatable sweeper brush 5 that lifts and lowers the ballast B, and the ballast B scraped up by the rotary sweeper brush 5 is conveyed by the conveyors 7, 7 either inside the rail R or on the roadside A1. It is possible to selectively discharge and perform repair work of the roadbed A at the same time as cleaning work. In addition, the sweeping chute 6 interposed between the conveyors 7, 7 and the rotary sweeper brush 5 is moved by the slide cylinder 31. By reciprocating in the front-rear direction, and by raising and lowering the sweep chute 6 in conjunction with the longitudinal movement of the sweep chute 6 by the tilting cylinder 36,
The ballasts B scattered on the sleeper M inside the rail R can be reliably swept out to the conveyors 7 and 7, and when the rotary sweeper brush 5 is stopped, the remaining sweeping of the ballasts B can be reduced. Further, the rotating brush 9 attached to the rearmost part of the traveling vehicle 1 is connected to the fastening portion R1 of the rail R.
As a result, the ballast B of the fastening portion R1 can be reliably swept out, thereby improving workability during wire keeping.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example,
The basic structure of the traveling trolley and the rotary sweeper brush, the raising and lowering means of the mounting frame for the rotary sweeper brush, the locking means, the sliding means of the sweeping chute, and the tilting means may be appropriately set.
