DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a point lubrication apparatus for smooth sliding of a tongue rail at a branch portion of a track.

[0002]

2. Description of the Related Art The most basic point change is performed by sliding a tongue rail on a floor plate.
For this reason, the force required to change points greatly changes depending on the state of contact and lubrication between the floor plate and tong rail,
When the condition is bad, it may cause a switch failure.

[0003] For this reason, conventionally, for example, a point lubrication apparatus as shown in FIG. 4 has been used. The point lubrication device 110 digs down ballasts between sleepers, inserts an arm 113 from outside the basic rail 111, and attaches a roller 115 to the tip of the arm 113. The point changing force is reduced by sliding the roller 117 on the roller 115.

[0004] Although the point turning force can be reduced by the point lubrication device 110, there are the following problems.

[0005]

In this type of conventional point lubrication apparatus 110, it is important to adjust the height of the arm 113. However, the weight of the tongue rail 117 itself is about 8%.
Since it is about 0 kg / m, there is a problem that the tip gradually sinks and it is difficult to convert the tongue rail 117 to a position where it contacts the basic rail 111. For this reason, conventionally, the mounting position of this point lubrication device 110 had to be frequently adjusted, and many man-hours were required for maintenance.

Further, as a result of using lubricating oil to improve the sliding of the roller 115, there is also a problem that the ballast is contaminated with oil by the lubricating oil. Usually, old ballasts are reused as construction materials, but if they are contaminated with oil in this way, they cannot do so, and must be disposed of as waste materials.

Further, in track maintenance, what is called a multi-tie operation using a multiple tie tamper is important. However, it is difficult to perform the multi-tie operation with a machine at a place where the point lubrication device 110 is embedded. This also requires manual work, and this also causes an increase in man-hours for maintenance work.

Accordingly, the present invention provides a rolling and lubricating apparatus that is easy to maintain after installation, does not hinder the reuse of ballast, and does not hinder multi-tie work. The purpose is to:

[0009]

Means for Solving the Problems, Embodiments of the Invention, and Effects of the Invention In the present invention, a roller lubrication apparatus is provided with a roller attached to a tongue rail so as to project toward the center of a track, and the roller is attached to the tongue rail. A roller rail supported from below is mounted on a sleeper, and an upper surface of the roller rail is provided with an inclination,
The inclination is such that when the tong rail is brought into contact with the basic rail, the tong rail is grounded on the floor plate and the roller is in a state of floating from the roller rail ,
It is formed so as to float the tongue rails from the floor plate roller when moving in a direction to separate the tongue rail from the base rail is grounded to the inclination of the roller rail, the low
The bracket is shaped to hold the tongue rail legs.
It is characterized by being attached to a racket piece .

[0010] According to this rolling contact lubrication device, when the tong rail is separated from the basic rail by the point change, the roller runs on the roller rail according to the movement of the tong rail, and the tong rail is moved from the floor plate along the inclination thereof. Let it rise. As a result, the tongue rail receives only a small friction, and smoothly executes the point changing operation. When the tongue rail is moved so as to approach the basic rail, the tongue rail descends while approaching the basic rail, and is firmly supported by contacting the floorboard. Therefore, the tong rail exerts a sufficient supporting force against the passage of the train.

As described above, since the roller lubrication apparatus of the present invention uses the roller rails supported by the sleepers, it does not sink and does not require any man-hours for adjustment after installation. Moreover, the ballast between the sleepers does not become a hindrance to the multi-die operation, and the multi-die operation using a machine is possible. In addition, even if lubricating oil is used to improve the sliding of the rollers, it only falls on the sleepers and does not stain the ballast with oil. As a result, it does not prevent the old ballast from being reused as construction material.

In the present invention, the upper surface of the roller rail may be constituted by an inclined portion whose height increases from the side of the basic rail toward the center of the track and a horizontal portion ahead of the inclined portion. Although all the roller rails may be formed by slopes, the requirement that the tong rails should be surely turned away from the floor plate cannot be completely satisfied. Note that the inclination according to the present invention may use an arc surface.

In the present invention, the roller has a diameter such that the lower surface of the roller protrudes below the lower surface of the tongue rail, and the upper surface of the horizontal portion of the roller rail is lower than the upper surface of the floor plate. It is good to By doing so, the upper surface of the roller rail does not protrude above the upper surface of the floor plate, so that it does not become an obstacle, and there is an advantage that the apparatus is not enlarged.

It is preferable that two roller rails are provided so as to sandwich the floor plate, and the rollers are attached to each roller rail. This is because, when the tongue rail is supported only by the roller rail, the supporting force is increased, and the operation can be stabilized, which is further advantageous.

[0015]

Next, an example will be described for better understanding of the embodiment of the present invention. As shown in FIG. 1, the roller lubrication device 10 of the embodiment attaches a roller 13 to a tongue rail 11 so as to protrude toward the center of the track and a roller rail 15 for supporting the roller 13 from below. It is configured to be mounted on a sleeper 17. The roller rail 15 is a floor plate 1 also mounted on a sleeper 17.
The rails 9 are configured as rails extending in the length direction of the sleepers 17 beside them. The roller rail 15 and the floor plate 19 are both made of a steel plate.

As shown in FIG. 2, the roller rail 15 has an inclined portion 23 at the end on the side of the basic rail 21 and a horizontal portion 25 ahead of the inclined portion 23. Then, while being held down from above by the holding plate 27, the sleepers 17 are fastened by bolts.
Is to be fixed. The holding plate 27 is made of a steel plate that projects laterally from the roller rail 15 and is further provided with two square holes 28 for driving a wedge for preventing rotation. In this embodiment, a spacer 29 is interposed between the pressing plate 27 and the roller rail 15. Further, the height of the horizontal portion 25 of the roller rail 15 is designed to be slightly lower than the floor plate 19. Therefore, the roller rail 15
Does not protrude above the floorboard 19.

On the other hand, the roller 13 is mounted on a mounting bracket 30 as shown in FIG. The mounting bracket 30 includes a band plate 31 for fixing to the tongue rail 11 and a bracket piece 33 welded and fixed so as to project at right angles to the band plate 31. The strip 31 is provided with oblong holes 35, 35 for fastening bolts to the tongue rail 11. The bracket piece 33 includes a cut 37 so as to hold the leg 11 a of the tongue rail 11 and a boss 39 for attaching the roller 13. The boss 39 is a bracket piece 3
3 and fixed by welding after being inserted into the circular hole provided. Then, a stopper pin 41 is inserted into the boss 39 so that the roller 13 is pinched between the stopper plate 43 of the stopper pin 41 and the boss 39 so as not to come off.

As shown in FIG. 3D, the stopper pin 43 serves as a support shaft for the roller 13.
The twisted portion 51 and the portions 53 and 55 ahead thereof are eccentric. Therefore, in a state where the nut is screwed and fixed to the threaded portion 55 at the tip, the stopper pin 41 does not rotate due to the rotation of the roller 13 and the nut does not loosen.

As the roller 13, for example, a roller having a bearing structure such as a ball bearing is used, and attention is paid so that rotation is smoothly performed. The roller 13 has a diameter that protrudes below the lower surface of the leg 11a of the tongue rail 11.

According to this embodiment, in a state contacting the tongue rail 11 to the base rail 21, as shown in FIG. 1 (B), the lower surface of the tongue rail 11 is grounded to the floor plate 19, the roller 13 roller It is designed to be in a state of floating from the rail 15. Therefore, the load of the train is
9 firmly supported.

On the other hand, the tongue rail 11 is
When the roller 13 is moved in the direction of separating from the tongue rail 11, the roller 13 contacts the inclined portion 23 of the roller rail 15 and
Run toward the center of the track while pushing up. As a result,
The tongue rail 11 rises from the floor plate 19 and does not receive a large frictional force. Therefore, the point change operation becomes smooth. The dynamic friction coefficient when the roller 13 and the roller rail 15 are in contact with each other is sufficiently smaller than the dynamic friction coefficient when the floor plate 19 and the tongue rail 11 are in contact with each other. Can be greatly reduced.

Further, since the roller 13 is located on the sleeper 17, even if lubricating oil is applied thereto, it does not fall on the ballast and does not contaminate the ballast, so that the old ballast can be reused as a construction material. It does not hinder the use. further,
Since the point lubrication apparatus 10 of the embodiment is not buried in the ballast, it does not hinder the multi-tie operation.

In the present embodiment, the roller rail 15 does not protrude from the horizontal portion 25 above the floor plate 19, so that the roller rail 15 does not become an obstacle when the points are changed. Further, since the leg portion 11a of the tongue rail 11 is held by the bracket piece 33, the support of the roller 13 is strengthened, and the backlash of the roller 13 can be prevented well.

Although an embodiment has been described to more specifically describe the embodiment of the present invention, the present invention can be embodied in a form other than this embodiment.
