Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sand disperser that winds sand on treads of rails to cope with idling of train wheels.

  2. Description of the Related Art Conventionally, when moisture such as rain or snow enters between a train wheel (drive wheel) and a tread surface of a rail, a coefficient of friction between the wheel and the tread surface of the rail (hereinafter, simply referred to as a friction coefficient) is large. And the wheels slip (slip). For this reason, the occurrence of idling is prevented by scattering sand on the tread surface of the rail to increase the friction coefficient.

  In addition, some vehicles such as locomotives are equipped with a sanding device near the drive wheels and, if necessary, spread sand on the treads of the rails to control the re-adhesion of electric vehicles running while maintaining the friction coefficient. A device and a vibratory sanding device that evenly spreads sand on the tread surface of a rail are disclosed (for example, see Patent Documents 1 and 2).

  However, since not all vehicles are equipped with a sanding device, in practice, the track maintenance worker transports sand to the section where slipping has occurred or is expected to occur, and Sand is scattered on the treads of the rails to prevent idling.

  More specifically, the maintenance worker carries the container filled with sand to the site, while holding the container and moving the sand along the rail while gradually dropping the sand from the opening of the container to the tread surface of the rail. , Sand will be scattered on the tread of the rail.

  However, in such manual sanding work of a track maintenance worker, it takes a lot of time to spread sand over a long distance. In addition, in order to ensure that the sand drops on the treads of the rails, it is necessary to look directly at the rails. This is a safety issue. In addition, above all, there is a problem in that the maintenance worker is placed in an unreasonable posture such as a middle waist, so that a heavy burden is imposed on the body of the maintenance worker.

  It is an object of the present invention to provide a sand scatterer that can surely scatter sand on a tread of a rail without keeping a maintenance worker in an unreasonable posture.

In order to achieve the above object, the present invention provides
In a sander that rolls sand on the tread of the rail by moving while maintaining the track maintenance worker by hand,

(Embodiment)
[1. Configuration description]
Hereinafter, a sander according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated example.

[1-1. Description of configuration of sander]
The configuration of the sander according to the embodiment of the present invention will be described with reference to FIG. 1A is a front view illustrating an example of the configuration of the sanding device 100, FIG. 1B is a plan view illustrating an example of the configuration of the sanding device 100, and FIG. It is a side view which shows an example of a structure.

  As shown in FIG. 1, a sander 100 includes a container 1 filled with sand to be scattered on a tread surface of a rail, and a traveling unit 2 mounted on the tread surface of the rail so as to be movable along the longitudinal direction of the rail. A guide portion 3 that contacts the side surface of the rail to keep the running portion 2 from coming off the tread surface of the rail; and a rail provided at an opening of the container 1 to adjust the amount of sand discharged from the container 1 A drop amount adjusting unit 4 for dropping on the tread surface, a body unit 5 having a holding unit HD11 that a line maintenance worker holds when moving along the longitudinal direction of the rail, and a container holding unit for detachably holding the container 1. 6).

  The sander 100 includes a container holder 6 at the center and the tip of the main body 5, and the container 1 is mounted on the container holder 6. The container holding unit 6 holds the container 1 so that the opening of the container 1 comes into contact with the falling amount adjustment unit 4 when the container 1 is mounted. The traveling section 2 is provided at the tip of the main body section 5, and the guide sections 3 are provided on both sides of the traveling section 2.

  The container 1 is filled with a predetermined amount of sand to be scattered on the tread surface of the rail in order to cope with idling and has an opening, and the filled sand is discharged from the opening by gravity. For example, the container 1 may be a container dedicated to the sander 100 or a substitute such as a commercially available plastic bottle.

  The traveling section 2 is mounted on the tread surface of the rail so as to be movable along the longitudinal direction of the rail. For example, it is composed of a pair of wheels WH11 such as rubber rollers placed along the longitudinal direction of the rail, and the line maintenance worker grasps the grasping portion HD11 of the main body 5 which can be grasped and applies a force along the longitudinal direction of the rail. Is added, the wheel WH11 of the traveling unit 2 rotates on the tread surface of the rail and advances to move the sander 100 in the longitudinal direction of the rail.

  The guide portion 3 is made of two pieces of metal such as aluminum fixed to the left and right outside the running portion 2 in parallel with a width slightly larger than the width of the tread surface of the rail so that the running portion 2 does not deviate from the tread surface of the rail. It is comprised from the plate member made from. For example, when the traveling unit 2 is composed of two plate members fixed to a width slightly larger than the width of the tread surface of the rail, and the traveling unit 2 is about to deviate to the right in the traveling direction, the left guide member 3 is provided. By contacting the side surface of the rail, it can be prevented from further shifting to the right in the traveling direction, and the running portion 2 can be prevented from deviating from the tread surface of the rail.

  The falling amount adjustment unit 4 adjusts the amount of sand discharged from the opening of the container 1 and causes the sand to fall on the tread surface of the rail. For example, even if the amount of sand scattered on the tread of the rail is small, even if the amount of sand is large, it is not possible to appropriately cope with idling, the fall amount adjustment unit 4 adjusts the amount of sand scattered on the tread of the rail appropriately. Adjust so that

  Specifically, it has a fixing member 41 having a first opening AP21 as shown in the front view of FIG. 2A and a second opening AP22 as shown in the front view of FIG. 2B. As shown in the front view of FIG. 2C and the cross-sectional view of FIG. 2D, the first opening AP21 and the second opening AP22 are formed of a cap-shaped rotating member 42. At the overlapping position, the rotating member 42 is rotatably supported by the fixed member 41 by the supporting member 43.

  In the drop amount adjustment unit 4 configured as shown in FIGS. 2C and 2D, the first opening AP21 and the second opening AP22 are separated by rotating the rotating member 42. The amount of overlap changes, and as a result, the size of the opening formed in the drop amount adjustment unit 4 changes.

  More specifically, for example, when the rotating member 42 is rotated to the state shown in FIG. 3A, the first opening AP21 and the second opening AP22 do not overlap at all. Therefore, no opening is formed. That is, in the state of FIG. 3A, no sand falls from the fall amount adjustment unit 4 onto the tread surface of the rail.

  Further, for example, when the rotating member 42 is rotated to the state shown in FIG. 3B, the first opening AP21 and the second opening AP22 slightly overlap each other, so that a smaller opening is used. AP31 is formed. That is, in the state of FIG. 3B, a small amount of sand falls from the falling amount adjustment unit 4 to the tread surface of the rail.

  Further, for example, when the rotating member 42 is rotated to the state shown in FIG. 3C, the first opening AP21 and the second opening AP22 completely overlap each other. An opening AP32 is formed. That is, in the state of FIG. 3C, a large amount (maximum amount) of sand falls from the fall amount adjustment unit 4 to the tread surface of the rail.

  As described above, by appropriately rotating the rotating member 42 of the falling amount adjusting unit 4, the amount of sand falling on the tread surface of the rail can be adjusted.

  The main body 5 supports the whole of the sander 100, and is held by a line maintenance worker when moving along the longitudinal direction of the rail. For example, it is made of a metal pipe such as aluminum in order to keep sufficient strength. As shown in FIG. Is provided.

  The container holder 6 detachably holds the container 1. For example, two rectangular and ring-shaped first members HL11 provided at the central portion and the distal end portion of the main body 5 and made of a metal plate member such as resin or aluminum, and the opening portion of the container 1 at the time of mounting. And a second member HL12 as a support rod for supporting the falling amount adjusting portion 4 so as to be in contact therewith.

  Due to such a second member HL12 of the container holding unit 6, the opening of the container 1 comes into contact with the cap-shaped rotating member 42 of the drop amount adjustment unit 4, and more specifically, the opening of the container 1 Since the tip is inscribed in the inner wall of the cap of the rotating member 42, sand can be prevented from being directly discharged from the opening of the container 1, and the function of the drop amount adjusting unit 4 can be effectively operated.

[2. Explanation at the time of sanding work]
When performing the sanding operation by the sanding device 100, the track maintenance worker appropriately rotates the turning member 42 of the falling amount adjustment unit 4 to fill the container 1 and the sand is dropped on the tread surface of the rail by an appropriate amount. Above, as shown in FIG. 4, the running part 2 of the sander 100 is placed on the tread of the rail RL41, and the grip part HD11 of the main body part 5 is pushed out in the direction shown by the arrow PS41.

  At this time, the wheel WH11 of the traveling unit 2 rotates on the tread surface of the rail and advances due to the force applied to the grip portion HD11 of the main body 5, so that the sanding device 100 moves the tread surface of the rail RL41 in the direction indicated by the arrow MV41. Move up.

  Further, when the traveling unit 2 is about to deviate from the tread surface of the rail RL41 when the traveling unit 2 moves on the tread surface of the rail RL41, one of the guide units 3 provided on the left and right comes into contact with the side surface of the rail RL41. Then, the traveling portion 2 is maintained so as not to come off from the tread surface of the rail RL41.

  At the same time, since an appropriate amount of sand SD41 is falling on the tread of the rail RL41 from the opening formed in the drop amount adjusting unit 4, the rail RL41 of the sander 100 is moved along with the longitudinal movement of the rail RL41. Sand SD41 is uniformly scattered on the tread.

  That is, since the maintenance worker need only push the grip portion HD11 of the main body 5 in the direction indicated by the arrow PS41, the rail maintenance worker can easily perform the railing even at a long distance compared to the manual sanding work. Sand SD41 can be scattered on the tread of RL41.

  Specifically, when a container having a capacity of 2 liters is used as the container 1 and the sand is completely filled, the sand can be scattered on the tread of the rail of about 1000 m.

  In addition, since the traveling portion 2 can be prevented from deviating from the tread surface of the rail RL41 by the guide portion 3, it is not necessary to look directly at the rail RL41, and it is possible to secure the field of view of the maintenance worker and to be able to respond to the approach of the train. Become.

  Further, since the maintenance worker only has to push the grip portion HD11 of the main body 5 in the direction shown by the arrow PS41, the maintenance worker scatters the sand on the tread surface of the rail without being forced into an excessive posture such as a middle waist. be able to.

  As described above, the container 1 that can be filled with a predetermined amount of sand and discharges the filled sand from the lower end opening by gravity, the holding portion HD11 that can be gripped by a worker by hand, and the container holding that holds the container A body portion 5 having a portion 6, a traveling portion 2 provided at a lower end portion of the body portion 5 and mounted on a tread surface of the rail so as to be movable in a longitudinal direction of the rail, and rails provided on both sides of the traveling portion 2 A guide portion 3 which contacts the side surface of the rail and keeps the running portion 2 from coming off the tread surface of the rail; By providing the falling amount adjusting portion 4 to be held, the track maintenance worker grips the grip portion HD11 of the main body portion 5 and moves the traveling portion 2 maintained on the tread surface of the rail by the guide portion 3 along the longitudinal direction of the rail. Just by moving, from the drop amount adjustment unit 4 Since the amount of sand is sown in the tread of the rail, without having to face up to the rail, without track maintenance workers is unreasonable attitude, it is possible to sow the sand to the tread of reliable rail.

In the description of the embodiment, the case where the container 1 is mounted on the container holding portion 6 is described. However, a plurality of containers 1 filled with sand are separately transported, and a sanding device is used at a sanding work site. The sanding work may be performed after the container 1 is attached to the container holding portion 6 of 100.
In this case, the weight of the sander 100 is reduced, and the sander 100 can be easily transported to the sanding work site. Further, when the sand in the container 1 runs out during the sanding work, the sanding work can be easily replaced with another container 1 and the sanding work can be continued, so that the work efficiency is improved.

  When the sander 100 in which the container 1 filled with sand is mounted on the container holder 6 is transported to a sanding work site, the turning amount of the turning member 42 of the drop amount adjusting unit 4 is adjusted. By reliably displacing the first opening AP21 and the second opening AP22 so that no opening is formed in the falling amount adjustment unit 4, no sand is scattered on the tread surface of the rail, so that unnecessary consumption of sand is reduced. Can be suppressed.

  Further, needless to say, the container 1 may be directly fixed to the main body 5 without the container holding portion 6 for detachably holding the container 1. In such a configuration, when the container 1 is filled with sand, the sand may be filled from the opening of the container 1 or the sand may be placed on the side opposite to the opening of the container 1 in order to improve work efficiency. May be provided.

  In the description of the embodiment, the traveling unit 2 includes a pair of wheels WH11. However, the number of the wheels WH11 may be any number from 1 to an arbitrary number according to the width of the tread surface of the rail. The material of the wheel WH11 is not limited to an elastic body (rubber roller), but may be any material such as a metal or a resin that can realize the function of the wheel WH11.

  In the description of the embodiment, the guide portion 3 is composed of two metal plate members such as aluminum fixed to a width slightly larger than the width of the tread surface of the rail. Since friction noise is generated when the rail 3 comes into contact with the side surface of the rail, a buffer member such as a resin or an elastic body may be provided on the guide portion 3 which is in contact with the side surface of the rail to suppress the generation of the friction noise. .

  In the description of the embodiment, as shown in FIG. 4, on the tread surface of the rail RL41, the maintenance worker moves the sanding device 100 while pushing in the direction shown by the arrow MV41. Of course, the track maintenance worker may move the sander 100 while pulling in the direction opposite to the direction indicated by the arrow MV41.
