Description

[Technical field]

[0001] The present invention relates to a ballast sweeper. [Background technology]

[0002] Generally, after leveling work such as tamping the ballast bed of a railway track, work is carried out to remove ballast scattered on the sleepers and the top surface of the rails, to smooth out the ballast on the top surface of the bed, and to clean the ballast bed. Conventionally, as a ballast sweeper for performing such work, the following ballast sweeper has been known (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-287903 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional ballast sweeper described in Patent Document 1 was equipped with an engine and a generator on a single bogie, and used a single large rotating brush to flatten and clean the ballast between the left and right rails (inside the gauge) and on the outside of the rails (outside the gauge).

[0005] However, since the engine, generator, electric motor, hydraulic equipment, large rotating brushes, hydraulic cylinders, etc. are mounted on a single bogie, the following problems have arisen: (i) Because of its large weight, it had to be loaded onto a large trailer and transported to the work site. Moreover, once it arrived near the work site, it was extremely difficult to unload it from the trailer and move it onto the railroad tracks. (ii) In particular, it was extremely difficult, almost impossible, to get the ballast sweeper through the railroad crossing near the work site and set it up on the track (rail).

[0006] Therefore, an object of the present invention is to solve such problems and to enable a ballast sweeper to easily and quickly enter a railway crossing, be installed on the track (rail), and immediately begin work of leveling and cleaning the ballast on the trackbed. A further object of the present invention is to provide a ballast sweeper which can run and move not only on tracks (rails) but also on roads. [Means for solving the problem]

[0007] Therefore, the present invention comprises a road-rail hydraulic excavator vehicle and a ballast sweeper bogie which is connected to the hydraulic excavator vehicle so as to be able to run on land and on rails; the ballast sweeper bogie is divided into a first bogie at the front and a second bogie at the rear; the first bogie has wheels for running on rails, and a land running wheel unit can be attached via a detachable mechanism, and further comprises a main rotating brush device and a side outward discharge belt means which discharge ballast within the gauge; the second bogie has wheels for running on rails, and a land running wheel unit can be attached via a detachable mechanism, and is equipped with a driving source such as an engine generator and a hydraulic unit, and is equipped with a secondary rotating brush device which removes ballast that has gotten on the rail fastening portion.

[0008] In addition, a side plow was attached to the first bogie to remove ballast that exists outside the gauge. In addition, the side plow has an elastic plate that, when viewed in a plane, slopes toward the rear as it moves away from the rail in a lateral direction, and the metal retaining plate portion that holds the elastic plate is provided with a guide protrusion with a sloped edge that collides with an approaching sleeper from the front of the travel position and guides it upward; further, the metal retaining plate portion is attached to the lower ends of two guide rods that can be raised and lowered freely.

[0009] In addition, a pair of left and right rubber plates for protecting the rail fastening portion are provided on the first bogie at a position forward of the main rotating brush device to prevent ballast flying forward from colliding with the rail fastening portion while guiding the ballast to the intermediate area between the left and right rails. In addition, an in-gauge obstacle clearing device that collects ballast within the gauge in the central area, and an out-gauge obstacle clearing device that moves ballast outside the gauge to the side were attached to the rear end of the second bogie.

[0010] In addition, the ballast sweeper cart is divided into a first cart and a second cart, and in the cart separated state with land running wheel units attached to the first and second carts, each of the first and second carts is set to a weight that allows it to be moved on land by manual labor by eight or fewer workers. The main rotary brush device also includes a number of tubular steam hoses protruding radially from the rotary shaft.

[0011] In addition, the numerous steam hoses of the main rotating brush device are arranged in a reverse spiral shape from the longitudinal center of the rotating shaft to the left and right sides, and protrude radially outward; when the rotating shaft rotates, ballast that jumps out forward is configured to gather in the longitudinal center. In addition, the auxiliary rotating brush device has a plurality of tubular steam hoses protruding from one surface of the rotationally driven disk so as to rotate along the conical orbit surface; and the steam hoses are configured to rotate in a rearwardly inclined downward position so that, when the rail is viewed from the horizontal lateral direction, the central axis of rotation of the conical orbit surface intersects with the rail at an inclination angle of 50° to 80°. Effect of the Invention

[0012] According to the present invention, the first and second bogies can be easily transported (separately) to the vicinity of the work site, and can then be easily moved from the railway crossing onto the track (rail) by manual or road-rail hydraulic excavator. Therefore, ballast removal work, ballast flattening work, and trackbed cleaning work can be carried out quickly and efficiently. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The present invention will be described in detail below based on the illustrated embodiments. In Fig. 1, 1 is a hydraulic excavator vehicle, 2 is a ballast sweeper vehicle, and this ballast sweeper vehicle 2 is divided into a first front vehicle 21 and a second rear vehicle 22. The hydraulic excavator vehicle 1 is an excavation construction machine that is also called simply a hydraulic excavator, or generally a backhoe or power shovel, and is also called Yumbo (registered trademark).

[0015] As shown in Figures 2, 3 and 8, the first bogie 21 has a base frame 24 and wheels 23 for running on rails, and a land running wheel unit 26 can be freely attached to the base frame 24 via a detachable mechanism 25.

[0016] The following is a description of this land traveling wheel unit 26. At the lower end position, two wheels 26B, 26B are pivotally mounted so as to be freely rotatable about a horizontal shaft 26A, and the horizontal shaft 26A is fixed to the lower end of a portal yoke 26C. 26D is a telescopic jack, and includes an outer cylinder 27, an inner cylinder 28, and a handle 29. The outer cylinder 27 can be attached to the base frame 24 of the first carriage 21 via a detachable mechanism 25.

[0017] The inner cylinder 28 is inserted into the outer cylinder 27 in a telescopic manner so as to extend downward from the outer cylinder 27. 28The inner cylinder 28 and the outer cylinder 27 are non-rotating in the vertical direction. For example, the inner cylinder 28 and the outer cylinder 27 may both be made of square pipes. Also, in order to allow the inner cylinder 28 to freely extend and retract (protrude and retract) downward relative to the outer cylinder 27, a rack and pinion mechanism is provided that is made up of a pinion gear (not shown) fixed to the handle 29 and a rack (not shown) formed (attached) on the inner cylinder 28, and the vertical positions of the inner cylinder 28 and the wheels 26B can be adjusted by manually rotating the handle 29. The gate-shaped yoke 26C and the wheels 26B, 26B are aligned along the vertical axis L 28 Although it is freely rotatable (pivotable) around the shaft, the rotation (pivot) can be fixed by providing a pivot fixing pin 26E.

[0018] Furthermore, a brake pedal 26F is provided which, when the operator steps on it with his foot, fixes the turning and applies the brakes (braking) to the wheels 26B. The wheels 26B are made of plastic such as urethane or rubber, and are arranged in pairs (so-called twin wheels) to improve turning performance and prevent the wheels from slipping off into narrow grooves or the like.

[0019] 2 and 3, short channel members 25A, 25A, 25A, 25A having a U-shape in plan view are fixed to the vertical front and rear ends of the base frame 24. Small holes are formed in the channel member 25A in the horizontal direction in the front and rear directions.

[0020] On the other hand, as shown in FIG. 8, a short channel material 25B having a U-shape in plan view is fixed to an outer tube 27, and a difference in size between the left and right sides of the short channel material 25B and the short channel material 25A is provided so that they can be fitted together from the side.

[0021] Small holes are also provided in the channel material 25B in the front-rear horizontal direction, and the positions of both small holes are set so that the axes of both small holes coincide when both channel materials 25A, 25B are fitted together. By inserting connecting pins 31 through both small holes, the four land running wheel units 26, 26, 26, 26 can be attached to the first bogie 21, and the first bogie 21 can be switched to a land running state.

[0022] 1 to 3, the main rotary brush device 3 and the side outward discharge belt means 7 (described later) are provided for leveling the ballast within the gauge and discharging excess ballast to the outside of the rail (outside the rail). In FIG. 2, 4 denotes a hydraulic motor for driving the main rotary brush device 3. Further, at a position in front of the main rotary brush device 3, there are provided a front upwardly inclined ballast induction guide plate 6 and a side outward discharge belt means 7 for discharging ballast in one direction, either to the right or to the left.

[0023] 1, 4 and 5, the second bogie 22 has wheels 33 for running on rails, and a land running wheel unit 26 (see FIG. 8) can be attached via a detachable mechanism 25 (similar to that described above). Channel members 25A, 25A, 25A, 25A constituting a part of the detachable mechanism 25 are fixed to the front and rear ends of the vertical beams of the base frame 34 of the second bogie 22.

[0024] 4 and 5, the second carriage 22 is equipped with a driving source such as an engine generator 8 and a hydraulic unit 9. Here, the driving source drives the main rotating brush device 3, discharge belt means 7, etc. mounted on the first carriage 21, but also drives a part of the driving source as well as the auxiliary rotating brush devices 10, 10 (described later) mounted on the second carriage 22. That is, the auxiliary rotating brush device 10 mounted on the second bogie 22 is a device for removing ballast 40 placed on the rail fastening portion 12 that fastens the rail R to the sleeper 11.

[0025] 6 and 7 show a specific example of the hydraulic excavator 1, and the fact that it can be used both on rail and on road will be described below. The hydraulic excavator 1 has a crawler (track) 43 for running on land, and Figs. 6 and 7 show the crawler 43 in a simplified diagram. 45 The swing arms 45, 45 are arranged to swing up and down (as shown in FIG. 1), and a pair of left and right rail running wheels 46, 46 are provided with axles inserted at the ends of the swing arms 45, 45.

[0026] 7, the rear end of the hydraulic cylinder is the same as that of the hydraulic cylinder shown in FIG. 47 The swing arms 47, 47 are capable of swinging up and down (as shown in FIG. 1), and a pair of left and right rail running wheels 48, 48 are provided with axles inserted at the ends of the swing arms 47, 47.

[0027] 6 and 7 show the state in which the wheels 46, 46; 48, 48 are in the lower position and the vehicle can run on the track. In addition, in Fig. 7, a coupler 50 for connecting to the first bogie 21 or the second bogie 22 via the connecting rod 49 shown in Fig. 1 is shown. In Figures 1 to 3, such couplers 50 are also provided at the front and rear of the first bogie 21 and the second bogie 22, and as shown in Figure 1, the first bogie 21 and the second bogie 22 can also be freely connected by a connecting rod 49.

[0028] In Figure 1, the hydraulic excavator vehicle 1, the first bogie 21 and the second bogie 22 are successively connected by such connecting rods 49 etc., and the rail running wheels 46, 46, 48, 48 are rotated by the engine of the hydraulic excavator vehicle 1, allowing the first bogie 21 and the second bogie 22 to run along the track (rail R).

[0029] Furthermore, if the land running wheel units 26, 26, 26, 26 shown in Fig. 8 are attached to the first bogie 21 or the second bogie 22 via detachable mechanisms 25, 25, 25, 25 (not shown) and connected to the hydraulic excavator 1 in this attached state via the coupler 50 and the connecting rod 49 or the like, each of the first bogie 21 and the second bogie 22 can run on land. Of course, when running on land, the hydraulic excavator 1 in Figs. 6 and 7 is switched to a state in which the crawler belt 43 is in contact with the land.

[0030] In particular, since the ballast sweeper car 2 is configured to be divided into the first car 21 and the second car 22, the hydraulic excavator 1 is also light in weight and requires a relatively small horsepower. In addition, when the first bogie 21 and the second bogie 22 are in a separated bogie state and the land running wheel units 26, 26, 26, 26 are attached as described above, each of the first bogie 21 and the second bogie 22 can be made heavy enough to be run on land by the manual labor of eight or less workers.

[0031] Returning to the explanation of the first bogie 21, the first bogie 21 is provided with the above-mentioned main rotating brush device 3, but as is clear from Fig. 1, this main rotating brush device 3 can only process ballast between the rails R - inside the gauge - but is not applicable to the outside of the rail R - outside the gauge. Therefore, a side plow 15 is attached to the first bogie 21 in order to remove ballast that exists outside the gauge.

[0032] 11 to 14 show an example of a side plow 15. This side plow 15 has an elastic plate piece 16 (made of a rubber plate) that inclines rearward--the opposite direction to the traveling direction--in a plan view as it moves away from the rail R in a lateral outward direction. Reference numeral 17 denotes a metal holding plate portion that holds the elastic plate piece 16. As shown in FIG. 13, this metal holding plate portion 17 has a rectangular upper cutout 17A in the center of the upper side, and a rectangular lower cutout 17B formed on the rail R side of the lower side, with a small cutout 17C formed at an inner corner of the upper side of this rectangular lower cutout 17B.

[0033] The elastic plate piece 16 consists of a first rubber plate 16A in the shape of a horizontally elongated rectangle (on the outer side) and a second rubber plate 16B in the shape of a substantially square (on the inner side). Although not shown in Figures 11 to 13, mounting bolt holes are drilled in the metal retaining plate portion 17 and the elastic plate piece 16, and they are fixed to each other and assembled using a perforated strip plate (not shown) with bolts and nuts, as shown in Figures 11 and 12.

[0034] As shown in FIG. 12B, the inclination angle θ of the side plow 15 (in a plan view) with respect to the traveling direction V of the first carriage 21 is 0 is freely changeable within the range of 35° to 55°, and the inclination angle θ 0The angle can be changed via a rotator 18 attached to the cutout portion 17A.

[0035] Furthermore, the side plow 15 is equipped with two guide rods 19, 19 that can be raised and lowered freely. That is, the guide rod 19 (made of a square pipe) is inserted into an outer (square) pipe 20 fixed to the base frame 24 of the first carriage 21 so as to be movable up and down, and a metal holding plate portion 17 is attached to the lower end of this guide rod 19.

[0036] For example, the upper ends of a pair of guide rods 19, 19 are connected and a handle 35 is fixed to allow the lower metal holding plate 17 and elastic plate 16 to be raised and lowered manually. In this way, it can be raised in a section of the track where an obstacle exists or when moving backward. It is also possible to provide an air cylinder or the like so that it can be raised and lowered by air.

[0037] 11 to 14, reference numeral 13 denotes a thick plate-like guide projection made of low-friction plastic or the like. This guide projection 13 is attached to the aforementioned metal holding plate portion 17 which holds the elastic plate piece 16. A part of the upper side of guide projection 13 is inserted into small cutout portion 17C shown in Fig. 13, and guide projection 13 is made to protrude from metal holding plate portion 17 so as to form a right angle in a plan view.

[0038] In particular, the guide piece 13 has an inclination angle θ of 35° to 55° as shown in FIG. 13 The sleeper 36 is shown in Fig. 11 and Fig. 14. Fig. 14(B) shows the moment when the sloped edge 13A of the guide piece 13 collides with the sleeper 36 approaching from the front position while the first bogie 21 is traveling on the rail (rail track) R. At the moment of collision, the sloped edge 13A of the guide piece 13 is inclined at a predetermined inclination angle θ 13 The slope edge 13A has an upward vector F 13 As a result, the elastic plate piece 16 moves upward. In other words, it is possible to prevent the lower edge of the elastic plate piece 16 from colliding with the sleeper and causing (early) damage.

[0039] At this time, since the guide rods 19, 19 can slide upward relative to the square pipe 20 and rise (as described above), the vector F 13 It can handle. The side plow 15 is preferably attached to the first carriage 21 (in the front-rear direction) in a position forward of the main rotary brush device 3 (to the left in the drawings) in Figs.

[0040] Next, in Figures 9 and 10, rubber plates 30, 30 for protecting the rail fastening portion are attached to the first bogie 21 at a position forward (in the direction of travel) of the main rotating brush device 3 to prevent ballast within the gauge from being splashed away by the main rotating brush device 3 and colliding with the rail fastening portion 12.

[0041] Moreover, the left and right rubber plates 30, 30 function to guide the ballast to the intermediate region between the left and right rails R, R. That is, FIG. 9 shows, in a simplified diagram, a state in which the ballast 40 hits the rubber plates 30, 30 and is guided as indicated by arrows G, G.

[0042] In other words, the pair of left and right rubber plates 30, 30 are arranged in a V-shape in plan view, so that the ballast 40 can be guided in the direction of the arrows G, G. Also, as shown in Fig. 10, the rubber plate 30 abuts (slides) against the inner surface of the rail R, and is slightly elastically deformed, causing one vertical side 30L to become concave.

[0043] As shown in FIG. 15 and FIG. 4, the rear end of the second bogie 22 is provided with a gauge clearance deflector 41, 41. The gauge clearance deflector 41, 41 serves to collect the ballast 40 in the gauge to the center area on the left and right (arrow N in FIG. 4). 41 16, 17 and 4, the ballast 40 outside the gauge is arranged to the outside (arrow N in FIG. 4). 42 The rails are equipped with outside gauge obstacle clearing devices 42, 42 that move from the rail to the outside gauge.

[0044] As shown in Fig. 15, the gauge obstacle deflector 41 has a metal mounting member 41A, a horizontal metal member 41B fixed to the lower end thereof, and a rubber plate 41C suspended from the horizontal metal member 41B. Moreover, as shown in Fig. 4, the pair of gauge obstacle deflectors 41 on the left and right are arranged symmetrically on the left and right in a plan view with the horizontal metal member 41B and the tip end 41E of the rubber plate 41C inclined backward in the running direction.

[0045] As shown in Fig. 15, the outside gauge obstacle deflector 42 has a metal mounting member 42A, a horizontal metal member 42B fixed to the lower end of the metal mounting member 42A, and a rubber plate 42C. Moreover, as shown in Fig. 4, the outside gauge obstacle deflector 42, which is separated and disposed on the left and right sides in a plan view, is disposed in an inclined manner such that the metal member 42B and the tip end 42E of the rubber plate 42C are located rearward in the traveling direction.

[0046] Next, a description will be given of the main rotating brush device 3. As shown in Fig. 19, the main rotating brush device 3 includes a number of steam hoses 52 protruding radially from a rotating shaft 51 made of a cylindrical body or the like.

[0047] Specifically, as shown in FIG. 19, a number of holes 53 are drilled through a cylindrical rotating shaft 51, short round pipes 54 are inserted into the holes, and the holes are welded 55 so that the round pipes 54 protrude radially from the outer periphery of the rotating shaft 51.

[0048] Then, a joint pipe 56 having a convex rib formed on its outer circumferential surface is inserted into the steam hose 52 cut to a predetermined length, and the pipe 56 is fixed integrally with the hose by a hose band metal fitting 57. The pipe 56 is then inserted into the short round pipe 54 and fixed by a fastener 58 such as a screw.

[0049] Fig. 18 is a 360° development of the outer circumferential surface of the rotating shaft 51 shown in Fig. 19. That is, Fig. 18 is a diagram for explaining the mounting position of the base end of the steam hose 52 shown in Fig. 19. Alternatively, Fig. 18 can be said to be a 360° development of the installation position of the round pipe 54 in Fig. 19 on a plane.

[0050] 18 and 19 reveal the following: In the main rotating brush device 3, a large number of steam hoses 52 (of a predetermined length) are arranged in a reverse left-right spiral from the longitudinal center 51M of the rotating shaft 51 toward the left and right sides, and are provided so as to protrude radially outward.

[0051] In the development of Figure 18, arrow M 3 indicates the running direction of the surface (circumferential surface) of the rotating shaft 51 during the rotational motion. The following can be seen from FIG. That is, when the rotating shaft 51 is rotating, the ballast that jumps out forward is gathered at the center 51M of the rotating shaft 51 in the longitudinal direction. That is, as shown in Fig. 1, the main rotating brush device 3 is disposed inside the left and right rails R, R - within the gauge - but if the ballast thrown forward by the numerous steam hoses 52 while the rotating shaft 51 is rotating jumps parallel to the rail R or to the left and right sides, there is a risk that it will accumulate inside the rail R and on the rail fastening portion 12. In other words, such a risk can be eliminated by having the ballast gather at the longitudinal center 51M of the rotating shaft 51 (as explained in Fig. 18).

[0052] Next, regarding the auxiliary rotating brush device 10, as shown in Figures 4, 5 and 20, a plurality of tubular steam hoses 62 are protruded in an inclined axial direction from one surface of a disk 60 which is driven to rotate by a gear motor 59 so as to rotate along a conical orbital surface 65.

[0053] The rotation center axis L of the conical raceway surface 65 65 When viewed from the horizontal lateral direction, the steam hose 62 intersects with the rail R at an inclination angle β of 50° to 80°. That is, when viewed from the lateral direction of the rail, the steam hose 62 performs a rotational motion with a rearward downward inclination, and removes ballast with a focus on the rail fastening portion.

[0054] As shown in Fig. 20, the inclination angle β can be changed (adjusted) by manually rotating the upper handle 61. Also, as shown in Figs. 4 and 5, the auxiliary rotary brush device 10, the inside gauge obstacle deflector 41, and the outside gauge obstacle deflector 42 are provided with a lift adjustment means 63 for moving and adjusting them up and down as indicated by the arrow H.

[0055] As described above in detail, the present invention comprises a road-rail hydraulic excavator vehicle 1 and a ballast sweeper car 2 which is connected to the hydraulic excavator vehicle 1 so as to be capable of traveling on land and on rails; the ballast sweeper car 2 is divided into a first car 21 at the front and a second car 22 at the rear; the first car 21 has wheels 23 for traveling on rails, and a land traveling wheel unit 26 can be attached via a detachable mechanism 25, and further comprises a main rotating brush device 3 for discharging ballast within the gauge and a side outward discharge belt means 7; The second bogie 22 has wheels 33 for running on rails, and can have land running wheel units 26 attached via detachable mechanisms 25. It is also equipped with driving sources such as an engine generator 8 and a hydraulic unit 9, and is equipped with a secondary rotating brush device 10 for removing ballast 40 on the rail fastening portion 12. Therefore, the weight of each of the separated first bogie 21 and second bogie 22 can be reduced compared to conventional methods, making them easy to transport, and facilitating the work of moving them from the road (land) onto the track (rail R) at railroad crossings and the like, allowing for rapid work. Furthermore, a small hydraulic excavator 1 is sufficient.

[0056] In addition, the first bogie 21 is equipped with a side plow 15 for removing ballast that exists outside the gauge, so that ballast that exists outside the gauge can be easily and reliably removed, and the main rotating brush device 3 is made lighter and simpler, and ballast is not unnecessarily kicked away.

[0057] In addition, the side plow 15 has an elastic plate piece 16 that, in a plan view, inclines toward the rear of the traveling direction as it moves away from the rail R in a lateral outward direction, and a guide projection 13 with a sloped edge 13A is attached to the metal retaining plate portion 17 that holds the elastic plate piece 16, which guides the approaching sleeper 36 upward while colliding with it from the front of the traveling direction; further, the metal retaining plate portion 17 is attached to the lower ends of two guide rods 19, 19 that can be raised and lowered freely, so that even if the sleepers 36 collide with each other one after another from the front of the traveling direction, the sloped edge 13A allows the side plow 15 to smoothly escape upward, preventing damage to the elastic plate piece 16 and significantly extending the life of the elastic plate piece 16 (excellent durability).

[0058] In addition, a pair of left and right rail fastening portion protecting rubber plates 30, 30 are provided on the first bogie 21 at a position forward of the main rotating brush device 3 to prevent ballast flying forward from colliding with the rail fastening portion 12 while guiding the ballast to the intermediate area between the left and right rails R, R.This prevents ballast bouncing forward from the main rotating brush device 3 from accumulating at the rail fastening portion 12, and subsequent ballast removal work in the vicinity of the rail fastening portion 12 can be simplified or omitted.

[0059] In addition, the rear end of the second bogie 22 is equipped with an in-gauge obstacle clearing device 41 that collects ballast within the gauge in the central area, and an out-gauge obstacle clearing device 42 that moves ballast outside the gauge outward, making it possible to easily and reliably remove ballast (without using power) from the vicinity of the rail R where it is most needed.

[0060] In addition, the ballast sweeper cart 2 is divided into a first cart 21 and a second cart 22, and in a cart separated state with land running wheel units 26, 26, 26, 26 attached to the first and second carts 21, 22, each of the first and second carts 21, 22 is set to a weight that allows it to be moved on land by manual labor of eight or less workers, so that even at a work site or in traveling conditions where it is difficult for a backhoe excavator 1 to enter, simple movement on land over short distances can be performed manually.

[0061] Furthermore, the main rotating brush device 3 is provided with a large number of tubular steam hoses 52 projecting radially from the rotating shaft 51, and therefore is highly durable and easy to replace.

[0062] In addition, the numerous steam hoses 52 of the main rotating brush device 3 are arranged in a reverse spiral from the longitudinal center 51M of the rotating shaft 51 to the left and right sides, protruding radially outward; since the ballast that jumps out forward when the rotating shaft 51 is rotating is configured to collect at the longitudinal center 51M, the excess ballast that is subsequently collected can be quickly and reliably discharged outward by the main rotating brush device 3. In addition, the subsequent removal work is facilitated so that no ballast remains near the rail R.

[0063] In addition, the auxiliary rotary brush device 10 has a plurality of tubular steam hoses 62 protruding from one surface of the rotationally driven disk 60 so as to rotate along a conical raceway surface 65; and when the rail R is viewed from the horizontal lateral direction, the central axis L of rotation of the conical raceway surface 65 is aligned with the central axis L of the rail R. 65 The steam hose 62 is configured to rotate with a rearwardly downwardly inclined posture so that it intersects with the rail R at an inclination angle β of 50° to 80°, so that the secondary rotating brush device 10 can finally beautifully remove ballast remaining near the inside and outside of the rail R.
