  Hereinafter, an embodiment of an idling suppression device 100 according to the present invention will be described in detail with reference to the drawings. However, although various technically preferable limitations for carrying out the present invention are given to the embodiments described below, the scope of the present invention is not limited to the following embodiments and illustrated examples.

FIG. 1 is a side view schematically showing a throwing and discharging maintenance vehicle 200 on which an idling suppression device 100 is mounted.
The idling suppression device 100 of this embodiment is used to realize an idling suppression method for suppressing idling of wheels of a railway vehicle (not shown) such as a train or a train.
As shown in FIG. 1, the anti-skid device 100 is mounted on both ends in the front-rear direction (left-right direction in FIG. 1) of a snow throwing maintenance vehicle (track maintenance vehicle) 200, specifically, on the rail R An obstruction mechanism 1 that removes fallen leaves, a liquid injection mechanism 2 that sprays a liquid (for example, water) to wash away resin on the top surface of the rail R, and a thick adhesive (for example, baked sand) on the top surface of the rail R Etc.) and a thickening agent spreading mechanism 3.
In the following description, the traveling direction of the snow and snow maintenance vehicle 200 is the front-rear direction, the arrangement direction of the two rails R, R is the left-right direction, and the direction perpendicular to the front-rear direction and the left-right direction is the up-down direction. To do.

First, the snow throwing maintenance vehicle 200 will be described.
The snow throwing / maintenance maintenance vehicle 200 shown in FIG. 1 includes, for example, a combined wing portion in which both a Russell device and a rotary device are provided on the front and rear sides of the vehicle body 210 in the traveling direction of the snow throwing / maintenance maintenance vehicle 200. 220 respectively. That is, the combined wings 220 and 220 are provided on the front side and the rear side in the traveling direction of the snow-removal maintenance vehicle 200 with respect to the wheels of the vehicle main body 210.
For example, when the snow-removal / maintenance vehicle 200 travels on a track with one direction (for example, the left direction in FIG. 1) as the traveling direction, one end side (for example, the left side) that is the front side in the traveling direction at the time of traveling. In the case where the track maintenance operation is performed using the combined wing portion 220 of the above-mentioned combination, and the vehicle travels on the track with the other direction (for example, the right direction in FIG. 1) as the traveling direction, the traveling direction is the front side during the traveling. The track maintenance work is performed using the combined blade portion 220 on the other end side (for example, the right side).

  Each of the combined wings 220 is equipped with the evacuation mechanism 1 and the liquid ejecting mechanism 2, and is added to the end of each of the combined use wings 220 of the vehicle body 210 (for example, both left and right ends in FIG. 1). Each of the adhesive spreading mechanisms 3 is mounted.

The snow and snow maintenance vehicle 200 is the same as a publicly known vehicle except that the idling suppression device 100 of the present embodiment is mounted, and the detailed structure of the snow and snow maintenance vehicle 200 is as follows. Description is omitted.
Moreover, although the throwing and snowing maintenance vehicle 200 is illustrated as the track maintenance vehicle, it is an example and not limited thereto, and a track maintenance vehicle other than the throwing and snow maintenance vehicle 200 may be used.

Next, the failure mechanism 1 will be described with reference to FIGS. 2 (a) and 2 (b).
FIG. 2A is a diagram showing the obstruction mechanism 1 as seen from the side, and FIG. 2B is a diagram showing the obstruction mechanism 1 as seen from above.

The fault-discharging mechanism 1 is disposed at a substantially central portion in the front-rear direction of each of the two combined wings 220 and 220 located on the front side and the rear side in the traveling direction of the snow-removal maintenance vehicle 200 (FIG. 1). reference).
That is, each obstacle mechanism 1 is provided on the front side in the traveling direction of the throwing and snowing maintenance vehicle 200 from the wheels of the throwing and snowing maintenance vehicle 200. For example, when the snow-removal maintenance vehicle 200 travels on a track in one direction (for example, the left direction in FIG. 1), the obstacle on one end side (for example, the left side) that is the front side in the traveling direction during this traveling. An operation of removing the fallen leaves on the rail R using the mechanism 1 (a fallen leaf removing step) is performed. On the other hand, when the snow throwing / maintenance maintenance vehicle 200 travels on the track in another direction (for example, the right direction in FIG. 1), the other end side (for example, the right side) that is the front side in the traveling direction during the traveling is exhausted. An operation of removing the fallen leaves on the rail R using the obstacle mechanism 1 is performed.

  Further, as shown in FIGS. 2A and 2B, the obstruction mechanism 1 has a contact plate portion 11 that comes into contact with the top surface of the rail R and removes fallen leaves on the top surface. ing. The contact plate portion 11 is disposed at a predetermined interval in the left-right direction so as to correspond to each of the two rails R, R.

  The contact plate 11 is, for example, a plate-like member having a substantially equal thickness over the entire region and having an outer shape formed in a substantially rectangular shape. The contact plate 11 is, for example, a member made of hard urethane so as to make it difficult to engulf fallen leaves between the contact plate 11 and the rail R. However, the contact plate 11 is an example and is not limited thereto. It can be arbitrarily changed as appropriate.

Further, the contact plate 11 is disposed so as to cross the rail R. The width of the contact plate 11 in the direction intersecting with the rail R is, for example, a width that prevents the contact plate 11 from coming out of the top surface of the rail R and releasing the contact with the rail R even in a sharp curve section (for example, 500 mm).
In addition, the contact plate 11 is positioned on the rear side in the traveling direction of the snow throwing maintenance vehicle 200 with respect to the inner end portion 11 i located outside the rail R and the outer end portion 11 o located outside the rail R. (See FIG. 2B). Further, the contact plate 11 is disposed so as to be inclined such that the lower end portion 11b that contacts the top surface of the rail R is located on the rear side in the traveling direction of the snow discharge / maintenance vehicle 200 with respect to the upper end portion 11u ( (See FIG. 2 (a)).
As a result, when the snow-removal maintenance vehicle 200 travels on the rail R in one direction, the contact plate 11 of the obstacle mechanism 1 slides on the top surface of the rail R to collect fallen leaves on the rail R or the rail R. I scraped the fallen leaves attached to the top of the head. Then, the fallen leaves on the rail R move along the inclined contact plate 11 and are dropped to the outside of the rail R and removed.

  In addition, although illustration is abbreviate | omitted, the contact plate part 11 can be moved up and down, for example, the operation | work which removes the fallen leaf on the rail R (foliage removal process), or the operation | work which flushes the resin of the top surface of the rail R mentioned later After completion of the (resin washing step), the contact plate 11 is retracted upward so that the contact with the rail R is released during the operation of spreading the thick adhesive.

Next, the liquid ejecting mechanism 2 will be described with reference to FIG.
FIG. 3 is a view showing the liquid nozzle 21 of the liquid ejecting mechanism 2 as viewed obliquely from above.

The liquid ejection mechanism 2 is disposed on the base end side (vehicle main body 210 side) of each of the two combined wing portions 220 and 220 located on the front side and the rear side in the traveling direction of the throwing and snow maintenance vehicle 200. Yes.
That is, each liquid ejecting mechanism 2 is forward of the traveling direction of the snow and snow maintenance vehicle 200 with respect to the wheels of the snow and snow maintenance vehicle 200 and the progress of the snow and snow maintenance vehicle 200 with respect to the fault mechanism 1. It is provided on the rear side. Then, each liquid ejecting mechanism 2 performs an operation (resin washing step) of washing the resin on the top surface of the rail R by ejecting liquid onto the rail R from which the fallen leaves have been removed by the obstruction mechanism 1 in the leaf removing step.
For example, when the snow and snow maintenance vehicle 200 travels along a track in one direction (for example, the left direction in FIG. 1), the liquid ejection on one end side (for example, the left side) that is the front side in the traveling direction during the traveling is performed. The mechanism 2 is used to wash away the resin on the top surface of the rail R from which the leaves have been removed in the leaf removal process. On the other hand, when the snow and snow maintenance vehicle 200 travels on the track in another direction (for example, the right direction in FIG. 1), the liquid on the other end side (for example, the right side) that is the front side in the traveling direction during this traveling. Using the ejection mechanism 2, an operation of washing away the resin on the top surface of the rail R from which the leaves have been removed in the leaf removal process is performed.

Further, as shown in FIG. 3, the liquid ejecting mechanism 2 includes a liquid nozzle 21 that diffuses and ejects a liquid (for example, water) radially.
The liquid nozzles 21 are arranged at a predetermined interval in the left-right direction so as to correspond to each of the two rails R, R.
Here, the arrangement of the liquid nozzle 21 is adjusted according to, for example, the angle at which the liquid is diffused, the distance from the rail R, and the like, but is not limited to this example. You may make it adjust the angle which diffuses a liquid, after fixing arrangement | positioning of the nozzle 21. FIG.

Then, by operating a pump (not shown), the liquid stored in a liquid tank (not shown) disposed at a predetermined position (for example, the base end portion of the combined use wing part 220) is passed through the pipe 22. To the liquid nozzle 21. The liquid nozzle 21 radiates and radiates liquid at a predetermined pressure toward the top surface and the inner side surface of the rail R that the wheels of the snow throwing / maintenance vehicle 200 and the railway vehicle contact. Thereby, the resin of the defoliation adhering to the top surface of the rail R is washed away, or the defoliation on the rail R remaining without being removed by the contact plate 11 of the obstruction mechanism 1 is blown off to the outside of the rail R. .
Here, the liquid includes water, but is not limited to this example, and may be, for example, a solution in which a component having a cleaning action is dissolved at a predetermined concentration. Moreover, the pressure which injects a liquid can be arbitrarily changed suitably considering the adhesion degree of the resin of the fallen leaf adhering to the rail R, the frequency which performs the said resin washing | cleaning process, etc., for example.

  In addition, although illustration is abbreviate | omitted, the liquid injection mechanism 2 may be equipped with the heat retention means (for example, heater etc.) for heat-retaining the liquid to inject at predetermined temperature.

Next, the thickening agent spreading mechanism 3 will be described with reference to FIGS.
FIG. 4 is a diagram schematically showing the storage container 31, the vibration part 32, and the delivery part 33 of the thickening agent spreading mechanism 3 when viewed in the front-rear direction. FIG. 5 is a perspective view showing the measuring shaft 331 of the delivery unit 33. Moreover, FIG. 6 is a figure which shows the increased adhesive nozzle 34 and the scattering suppression part 35 of the increased adhesive spreading mechanism 3 as seen from the side.

The thickening agent spreading mechanism 3 is arranged on the combined wing 220 side of the front and rear wheels in the traveling direction of the snow-removal maintenance vehicle 200 of the vehicle main body 210. In other words, the thickening agent spreading mechanism 3 is provided behind the wheels of the vehicle body 210 in the traveling direction of the throwing and discharging maintenance vehicle 200, and the resin of the fallen leaves is washed away by the liquid ejecting mechanism 2 in the resin cleaning process. An operation of spreading a thick adhesive on the top surface of the rail R (a thickening agent spreading step) is performed.
Specifically, for example, when the snow and snow maintenance vehicle 200 travels along a track in one direction (for example, the left direction in FIG. 1 and the like), the fallen leaf removal process and the resin cleaning process are performed, and the same track is turned back. When carrying out the thickening agent spreading step when traveling in another direction (for example, the right direction in FIG. 1), one end side (for example, the left side) that becomes the rear side in the traveling direction when traveling in the other direction. The thickening agent spreading mechanism 3 is used to spread the thickening agent on the top surface of the rail R from which the resin of the fallen leaves has been washed away by the resin washing process.
On the other hand, for example, when the snow throwing maintenance vehicle 200 travels along a track in one direction (for example, the left direction in FIG. 1 and the like), in addition to the leaf removal process and the resin cleaning process, The top of the rail R in which the resin of deciduous leaves has been washed away by the resin washing process using the thickening agent spreading mechanism 3 on the other end side (for example, the right side, etc.) that is the rear side in the traveling direction when traveling in one direction. The work of spreading the adhesive on the surface is performed.

  Further, as shown in FIGS. 4 to 6, the thickening agent spreading mechanism 3 includes a storage container 31 in which the thickening adhesive is stored, a vibration unit 32 that applies vibration to the storage container 31, and a storage container 31. A delivery unit 33 that delivers a predetermined amount of the increased pressure-sensitive adhesive, a pressure-sensitive adhesive nozzle 34 that discharges a pressure-sensitive adhesive (for example, baked sand) that is delivered by a predetermined amount by the operation of the delivery unit 33, and a pressure-sensitive adhesive nozzle 34 And a scattering suppressing part 35 that suppresses scattering of the thick adhesive discharged from the nozzle.

The storage container 31, the delivery unit 33, the thick adhesive nozzle 34, and the scattering suppression unit 35 are provided two by two so as to correspond to each of the two rails R and R.
The two storage containers 31, 31 are arranged at predetermined positions in the vehicle main body 210 (for example, the lower floor of the cab, etc.) with a predetermined interval in the left-right direction. Moreover, each storage container 31 is formed in the substantially funnel shape by which the upper end and the lower end opened, and the opening area of the lower end was made small with respect to the upper end, for example.
As shown in FIG. 4, a vibrating portion 32 for vibrating the storage container 31 is connected to the outer surface of each storage container 31.

The vibration unit 32 includes a vibration motor 321 that generates vibration, and a transmission frame 322 that transmits the vibration generated by the vibration motor 321 to the two storage containers 31 and 31.
The vibration motor 321 is disposed between the two storage containers 31, 31. The transmission frame 322 is a member that is long in the left-right direction, and a vibration motor 321 is attached and fixed at a substantially central portion thereof, and both left and right ends are fastened to the outer surface of each storage container 31.
Thereby, the vibration generated by driving the vibration motor 321 is transmitted to the two storage containers 31 and 31 via the transmission frame 322.

In addition, a delivery unit 33 is provided below each storage container 31. Specifically, for example, a pipe 36 is connected to the lower end portion of each storage container 31, and a delivery portion 33 is provided at a joint portion with the pipe 36.
The two delivery parts 33 and 33 are arrange | positioned at predetermined intervals in the left-right direction so that it may respond | correspond to each position of the two storage containers 31 and 31. As shown in FIG. Each delivery unit 33 includes a measuring shaft 331 for measuring the thickened adhesive, and a rotary motor 332 that rotates the measuring shaft 331 around the longitudinal axis.

As shown in FIG. 5, the measuring shaft 331 has a shaft portion 331 a that is long in the left-right direction.
The shaft portion 331a is formed by, for example, forming a columnar metal (for example, stainless steel), and a connection portion 331b to which the rotary motor 332 is connected is provided at one end portion. Further, the substantially central portion in the longitudinal direction of the shaft portion 331a is formed to have a small diameter with respect to other portions, and a plurality of plate-like portions 331d,... Are connected and fixed to the small diameter shaft portion 331c.

The plate-like portion 331d is, for example, a resin member that is long in the left-right direction and has substantially the same thickness. Further, the plurality of plate-like portions 331d,... Are radially arranged on the small diameter shaft portion 331c. Specifically, the plurality of plate-like portions 331d,... Has a short side extending in the radial direction of the small-diameter shaft portion 331c and a predetermined interval (for example, in the circumferential direction of the small-diameter shaft portion 331c). , 90 °, etc.). Thereby, the groove part 331e divided by two adjacent plate-like parts 331d and 331d among the plurality of plate-like parts 331d,... Is formed, and the adhesive is measured by a predetermined amount by the groove part 331e.
That is, when the measuring shaft 331 is rotated by driving the rotary motor 332, the thickening agent that has been freely dropped from the storage container 31 is measured by a predetermined amount by the groove portion 331 e facing the lower end opening of the storage container 31 of the measuring shaft 331. The Then, the measuring shaft 331 is rotated so that the groove portion 331e in which the predetermined amount of the increased adhesive is measured is further rotated by a predetermined angle (for example, 180 °), whereby the predetermined amount of the increased adhesive in the groove portion 331e is increased. It is sent out to the pipe 36 side connected to the agent nozzle 34 by free fall. At this time, since the resin plate-like portion 331d has flexibility, a thickening adhesive existing in a portion between the measuring shaft 331 and the storage container 31 is clogged, and rotation of the measuring shaft 331 is stopped. This can be suppressed.
Here, examples of the thickening adhesive include calcined sand, but it is only an example and is not limited to this. In order to improve the adhesion of the wheel to the rail R by being interposed between the rail R and the wheel. Any powdery or granular material may be used.

In addition, the dimension of the measurement shaft 331 corresponds to the dimension of the lower end opening of the storage container 31 disposed almost immediately above.
For example, the length in the left-right direction of the small-diameter shaft portion 331c and the plate-like portion 331d is equal to or longer than the length in the left-right direction of the lower end opening of the storage container 31. Further, the length in the front-rear direction of the small-diameter shaft portion 331 c and the plate-like portion 331 d of the measuring shaft 331 is equal to or longer than the length in the front-rear direction of the lower end opening of the storage container 31. .

The thick adhesive nozzles 34 are arranged at a predetermined interval in the left-right direction so as to correspond to each of the two rails R, R.
Each pressure-sensitive adhesive nozzle 34 is disposed substantially immediately above the top surface of each rail R, and is inclined so as to discharge the pressure-sensitive adhesive from the obliquely upward direction with respect to the top surface of the rail R. Specifically, the thick adhesive nozzle 34 is inclined so that the lower end portion forming the discharge port is located on the rear side in the traveling direction of the throwing and discharging maintenance vehicle 200 with respect to the upper end portion on the delivery portion 33 side. (See FIG. 6).
As a result, the thickening agent delivered from the delivery unit 33 via the pipe 36 is discharged from the lower end portion of the thickening agent nozzle 34 obliquely upward with respect to the top surface of the rail R, and is applied to the top surface of the rail R. I will be beaten.

The scattering suppression part 35 is arrange | positioned corresponding to the two thick adhesive nozzles 34 and 34 corresponding to each of the two rails R and R. As shown in FIG. Specifically, each scattering suppression part 35 is disposed so as to be located behind the thickening / adhesive nozzle 34 in the traveling direction of the throwing and discharging maintenance vehicle 200.
Moreover, the scattering suppression part 35 has the rubber-made inner side board part 351 and the outer side board part 352 arrange | positioned at each of the inner side and the outer side of the rail R, for example. The inner plate portion 351 and the outer plate portion 352 are arranged at a predetermined interval corresponding to the width in the left-right direction of the top surface of the rail R. Specifically, the rail R side surface of the inner plate portion 351 contacts the inner surface of the head portion of the rail R, and the rail R side surface of the outer plate portion 352 contacts the outer surface of the head portion of the rail R. It is the interval of the grade to do.
That is, when the thick adhesive is discharged from the thick adhesive nozzle 34, the inner plate portion 351 and the outer plate portion 352 of the scattering suppression portion 35 are arranged inside and outside the head of the rail R, It is possible to suppress spilling of the thick adhesive squeezed on the top surface of the rail R inward and outward.

  In addition, although illustration is abbreviate | omitted, the scattering suppression part 35 can be moved up and down, for example, the operation | work which removes the fallen leaf on the rail R (foliage removal process), or the operation | work which wash | cleans the resin of the top surface of the rail R (resin At the time of the cleaning step), the scattering suppressing portion 35 is retracted upward so that the inner plate portion 351 and the outer plate portion 352 do not contact the rail R.

  Although not shown, the idling suppression device 100 is configured to move the contact plate portion 11 up and down, operate the pump of the liquid ejecting mechanism 2, drive the vibration motor 321 and the rotation motor 332, and move the scattering suppression portion 35 up and down. You may provide the control box which controls etc. Note that these electrically controlled configurations may be integrated and controlled by, for example, control means (not shown) of the throwing and snow maintenance vehicle 200 itself.

Next, the idling suppression method using the idling suppression apparatus 100 according to the present invention will be described.
In the idling suppression method according to the present invention, the fallen leaf removing step of removing the fallen leaves on the rail R using the obstruction mechanism 1, and after the fallen leaf removing step, the liquid ejecting mechanism 2 is used for liquid (for example, water). A resin cleaning step of spraying and washing off the resin on the top surface of the rail R, and after this resin cleaning step, a thickening agent (for example, baked sand) is spread on the top surface of the rail R using the thickening agent spreading mechanism 3. A thickening agent spreading step is performed.

  Further, the fallen leaf removing process, the resin washing process, and the thickening agent spreading process are performed while the throwing and snowing maintenance vehicle 100 is traveling. Specifically, while the snow-removal and maintenance vehicle 200 travels in one direction (for example, the left direction in FIG. 1), the fallen leaf removal process and the resin cleaning process are performed, and the same track is turned in the other direction. During the traveling in the right direction (for example, the right direction in FIG. 1), the thickening agent spreading step is performed. In other words, the idling suppression device 100 mounted on one end side (for example, the left side, etc.) of the throwing / snow maintenance vehicle 100 in the front-rear direction is used, so Then, the fallen leaf removing process and the resin washing process are performed on the forward path, and the thickening agent spreading process is performed on the return path.

For example, when the fallen leaf removal process and the resin cleaning process are performed on the outward path of the track to be maintained of the snow-removal maintenance vehicle 100, the scattering suppression portion 35 of the thickening agent spreading mechanism 3 is placed on the upper side so as not to contact the rail R. Retracted.
When traveling in one direction of the snow throwing maintenance vehicle 200 is started, first, the contact plate 11 of the fault mechanism 1 slides on the top surface of the rail R to remove the fallen leaves on the rail R. (Leaf removal process). Then, liquid is ejected from the liquid nozzle 21 of the liquid ejecting mechanism 2 toward the top surface and the inner surface of the rail R at a predetermined pressure, and the resin of the fallen leaves adhering to the top surface of the rail R is washed away ( Resin washing step).
The leaf removal process and the resin cleaning process are continuously performed while the snow-removal maintenance vehicle 200 travels in one direction on the track to be maintained. Then, when the throwing and discharging maintenance vehicle 200 travels to the end point of the track to be maintained, the ejection of the liquid from the liquid nozzle 21 is stopped.

When the throwing / snow maintenance vehicle 100 is turned back and the thickening agent spreading process is performed on the return path of the track to be maintained, the contact plate 11 of the fault mechanism 1 is retracted upward so as not to contact the rail R; To do. Further, the vibration motor 321 of the vibration unit 32 of the thickening agent spreading mechanism 3 is driven to vibrate the storage container 31 via the transmission frame 322.
When traveling in the other direction of the snow throwing maintenance vehicle 200 is started, the rotation shaft 331 of the delivery unit 33 of the thickening agent spreading mechanism 3 is driven to rotate the measuring shaft 331 at a predetermined speed. The increased pressure-sensitive adhesive in the storage container 31 is sent to the pressure-sensitive adhesive nozzle 34 side by a predetermined amount, and the pressure-sensitive adhesive is discharged from the pressure-sensitive adhesive nozzle 34 to the top surface of the rail R (a pressure-sensitive adhesive spreading step). ). At this time, since vibration is imparted from the vibrating section 32 to the storage container 31, the thick adhesive can be spread while vibrating so that the thick adhesive inside the storage container 31 does not harden. Further, the scatter spilling part 35 spills from the top surface of the rail R to the inside and the outside of the rail R by the scattering suppression unit 35 disposed behind the throwing and discharging maintenance vehicle 200 relative to the thick adhesive nozzle 34. Is suppressed.
This thickening agent spreading step is continuously performed while the snow-removal maintenance vehicle 200 travels in the other direction on the track to be maintained. Then, when the throwing and discharging maintenance vehicle 200 travels to the end point of the track to be maintained, the discharge of the thick adhesive from the thick adhesive nozzle 34 is stopped.

As described above, according to the idling suppression device 100 of the present embodiment, after the fallen leaves on the rail R are removed, the resin of the fallen leaves adhering to the rail R can be washed, and then on the top surface of the rail R. The adhesion of the wheels of the railway vehicle to the rail R can be improved by spreading the thickening adhesive. At this time, since the thickening agent is spread while vibrating so that the thickening agent inside the storage container 31 does not harden, it is possible to prevent the thickening agent inside the storage container 31 from hardening. In particular, for example, moisture generated from the liquid ejecting mechanism 2 that ejects the liquid can be appropriately prevented from condensing inside the storage container 31 and solidifying the thickening adhesive, and can be increased from the thickening nozzle 34. The adhesive can be discharged stably.
Therefore, the cleaning of the rail R to which the fallen leaves are attached and the improvement of the adhesion of the wheel to the rail R can be performed efficiently, whereby the idling of the wheel of the railway vehicle can be appropriately suppressed.

Further, since the thickening agent nozzle 34 discharges the thickening agent from an obliquely upward direction with respect to the top surface of the rail R, the thickening agent discharged from the thickening agent nozzle 34 to the top surface of the rail R is the rail R. Can be prevented from spilling from the top surface to the inside or outside of the rail R.
Furthermore, it is possible to appropriately suppress the spillage of the thick adhesive on the top surface of the rail R from the inside or the outside of the rail R by using the scattering suppressing portion 35 disposed on the side of the rail R.

  Further, since the thickening agent spreading mechanism 3 has a delivery unit 33 that sends out the thickening agent in the storage container 31 to the thickening agent nozzle 34 side, the thickening agent nozzle 34 is activated by the operation of the delivery unit 33. The increased pressure-sensitive adhesive sent out in a fixed amount can be discharged, and the increased pressure-sensitive adhesive can be evenly spread on the top surface of the rail R.

  Further, the contact plate portion 11 that contacts the top surface of the rail R and removes the fallen leaves on the top surface is arranged so as to intersect the rail R, and an outer end portion 11o that is outside the rail R has an outer end portion 11o. The lower end portion 11b that is in contact with the top surface of the rail R on the rear side in the traveling direction of the throwing and discharging maintenance vehicle 200 with respect to the inner end portion 11i that is on the inner side of the rail R is thrown and discharged with respect to the upper end portion 11u. Since the snow maintenance vehicle 200 is inclined so as to be located on the rear side in the traveling direction, the fallen leaves on the rail R are dropped to the outside of the rail R by the contact plate portion 11, and the fallen leaves on the rail R are removed. It can be done properly.

  Moreover, since the liquid nozzle 21 diffuses and sprays the liquid radially toward the top surface and the inner side surface of the rail R, the resin of fallen leaves adhering to the top surface and the inner side surface of the rail R where the wheels of the rail vehicle come into contact. Can be washed away properly.

  In addition, since the litter removal process, the resin cleaning process, and the thickener spreading process are performed while the throwing / snow maintenance vehicle 200 is running, Removal, washing of the resin of the defoliation adhering to the rail R, and spreading of the thickening adhesive on the top surface of the rail R can be performed efficiently. In particular, the fallen leaf removal process, the resin cleaning process, and the thickening agent spreading process can be performed efficiently on the forward path and the return path in the reciprocating travel of the track of the throwing and snow maintenance vehicle 200.

The application of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.
For example, although not shown, the storage container 31 and the delivery unit 33 are covered with a covering member (for example, a waterproof sheet or the like) in order to prevent moisture from entering the storage container 31 or the like of the thick adhesive spreading mechanism 3. You may make it do.
