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 formed by squeezing ballasts laid below and around a sleeper and then cleaning ballasts scattered on the sleepers and rails, so that a railroad vehicle traveling along the rails can be used. It is capable of running safely and smoothly, and is a sweeper device for cleaning ballast scattered on the crossties and rails.
In Japanese Patent Application Publication No. 7 (1995) -175, a housing suspended from a hydraulic cylinder is provided on the rear side of a traveling vehicle, a rotating brush is provided in the housing, and a flexible skirt is attached to a lower end edge of the housing so as to be in close contact with a rail. There is a proposed sweeper device. 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 folded housing and fall as a result, and will again be scattered on the sleeper, and the ballast remaining on the sleeper cannot be effectively cleaned.

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, a railroad track ballast sweeper apparatus according to the present invention is provided with a ballast laid on a road shoulder portion of a railroad track on a traveling trolley running on a rail laid on the railroad trackbed. An inverted V-shape blade that rakes inside is attached, and a rotary sweeper brush that scrapes up the ballast raked by the blade is provided on the rear side of the blade, and a rotary sweeper brush is provided in front of the rotary sweeper brush in parallel with the rotary brush. A pair of right and left conveyors are provided, which are separated from each other at the substantially central portion of the rail, and the outer edges of which extend outside the rail, and the left and right conveyors are rotated forward and reverse with respect to each other. And a drive device for selectively discharging the ballast collected in step (1) to the inside of the rail or to the shoulder of the railway track floor.

[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 the ballast scattered on the crossties are swept up by the rotation of a rotary sweeper brush provided on the rear side of both blades, and are swept out onto the conveyor. The ballast collected by this conveyor is transported by the conveyor, but by selectively changing the rotation direction of this conveyor, if the ballast laid on the trackbed inside the rail is larger than the appropriate amount, both conveyors If it rotates outward, the ballast on both conveyors will be discharged to the road shoulder, while if the ballast is less than the appropriate amount, by rotating the conveyors inward each other, the ballast collected by the conveyor will pass through the gap between both conveyors. Can be refilled inside the rail.

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 the scraping plate 53 provided at the front end thereof is stretched, and then the two blades 8, 8 are operated by operating the cylinder 52. Is pivoted downward about the shaft 50 so that the scraping plate 53 extends to the shoulder A1 of the roadbed A and is landed. Further, the rotating brush 9 attached to the rearmost part of the traveling vehicle 1 is substantially 45 The rail R is contacted and fixed to the fastening portions inside and outside the rail R in a state where the rail R is inclined backward.

Then, the traveling vehicle 1 travels 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 guided along the guide hole 27 of the guide plate 25 by the slide plate 28 connected to the slide cylinder 29 by the expansion and contraction operation of the slide cylinder 29, whereby the sweep chute 6 is rotated. The sweeping chute 6 reciprocates back and forth between the sweeper brush 5 and the conveyors 7, 7.
By turning the link arm 30 fixed to 26,
The inclination angle of the sweep chute 6 changes. That is, the sweeping chute 6 falls down while moving forward (left side in the figure),
Conversely, when the sweeping chute 6 stands up while moving backward (to the right in the figure), and when the sweeping chute 6 is farthest from the rotary sweeper brush 5 (shown by a broken line in FIG. 6), the lower end of the sweeping chute 6 The portion is inclined forward so as to contact 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 rotary sweeper brush 5 and the sweep chute 6. After this, the rotary sweeper brush 5
Is slid rearward so that the lower end of the sweeping chute 6 is tilted so as to stand up (shown by a broken line in FIG. 5) so as to be in close contact with the rotating sweeper brush 5, thereby sweeping with the rotating sweeper brush 5. The ballast B accumulated in the gap between the chutes 6 can be swept out to the conveyors 7 by rotation of the rotary sweeper brush 5. That is, by changing the angle of the sweep chute 6 and sliding the sweep chute 6 back and forth, and repeating such an operation, the ballast B scraped up by the rotary sweeper brush 5
After a certain amount of water is collected by the sweep chute 6, the conveyors 7, 7 are swept out, so that the ballasts B scattered on the sleepers M inside the rail R can be reliably swept out to the conveyors 7, 7, and the rotary sweeper brush 5 Is stopped, the remaining unswept ballast B can be reduced. Even if the sweep chute 6 is moved back and forth, since the gap between the sweep chute 6 and the conveyors 7, 7 is closed by the cover 32, 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.
And the ballast B on the conveyors 7 and 7 is
, The direction of ballast B transfer can be changed depending on the direction of rotation of the conveyors 7,7. That is, the ballast B laid on the roadbed A inside the rail R
When the conveyors 7 and 7 are rotated outward from each other, the ballast B is conveyed in the direction of the arrow a shown in FIG. 7 and the conveyor chute 44 at the outer end of the conveyors 7 and 7 is rotated.
When the ballast B inside the rail R is smaller than an appropriate amount, the excess ballast B and the crossties M accumulated on the shoulder A1 by the two blades 8, 8 are scattered. When the ballasts B are collected by the conveyors 7 and 7 and the conveyors 7 and 7 are rotated in opposite directions and rotated inwardly, the collected ballasts B are transported in the direction of arrow b shown in FIG. V from the gap between
Even if the ballast B replenished inside the rail R is scattered on the sleeper M, the ballast B can be distributed to the left and right again by the character-shaped distribution plate 45 so as to be refilled. It can be swept out by the sweeper brush 5. That is, the ballast B collected by the conveyors 7, 7 is changed by changing the rotation direction of the conveyors 7, 7.
According to the laying state of the ballast B in the rail R, the ballast B can be selectively distributed to the inside of the rail R or to the roadside A1.

As described above, according to the present invention, the ballast B laid on the shoulder A1 of the railway track floor A is raked inward by the blades 8 and 8 in the shape of an inverted C attached to the traveling vehicle 1, and the blades 8 , 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 the repair work of the roadbed A simultaneously with the cleaning work. Further, as an effect of the above-described embodiment, the sweeping chute 6 interposed between the conveyors 7, 7 and the rotary sweeper brush 5 reciprocates in the front-rear direction by the slide cylinder 29, and the sweeping chute 6 by the tilting cylinder 31. By moving the sweep chute 6 up and down in conjunction with the forward and backward movement of the rail R, the ballast B scraped up by the rotary sweeper brush 5 is collected to a certain extent by the sweep chute 6 and then the conveyors 7 and 7 are swept out, so that the inside of the rail R The ballast B scattered on the sleeper M 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 It collects in the gap between the rotary sweeper brush 5 and the sweep chute 6 and does not mix into the roadbed A again. It can be kept low. Further, the ballast B of the rail R can be reliably swept out by the rotating brush 9 attached to the rearmost part of the traveling vehicle 1.
