DETAILED DESCRIPTION OF THE INVENTION
At the point where the basic rail that lays the floorboard on the sleepers and is fixed on the floorboard and the Tongler that moves toward and away from the basic rail are placed in pairs, the floorboard is supported at the position where the Tongler contacts the basic rail. And a separation bearing part in which the Tongrel retreats away from the basic rail. In the separation bearing part, the required number of bottom seat balls of the same small diameter is provided on the hemispherical concave bearing surface of the casing. The rolling large-diameter ball is accommodated on the bottom seat ball, the casing main body opening is closed by the lid plate to prevent the bottom ball from coming off, and the rolling large-diameter ball is opened from the opening of the lid plate. A part protrudes outward, and the outside is covered with a sealing cover that has an inner diameter that contacts the outer surface of the rotating large-diameter ball and that has an opening through which the rotating large-diameter ball passes. Is The bearing surface constituted by each apex of each ball bearing is set to be slightly higher than the conversion bearing portion, and there are a plurality of rows where the front and rear are slightly displaced laterally with respect to the moving direction of the Tongrel. when the tongue rail provided on the column is retracted moves, bearing devices of the tongue rail in points railway track which is arranged to support rises slightly to.
[0007]
【Example】
Hereinafter, the Tongleil support device at the point of the railway track according to the present invention will be described with reference to the drawings as an embodiment. As shown in FIGS. 1 and 2, a floor board 2 is laid on a sleeper 1 and the floor board 2 is placed on the floor board 2. A fixed basic rail 3 and a tongrel 4 moving toward and away from the basic rail 3 are arranged in pairs.
[0008]
The floor plate 2 has a conversion support portion 2a that supports the upper surface of the floor plate 2 at a position where the Tongler 4 contacts the basic rail 3, and a separation support portion 2b that retreats away from the basic rail 3 and does not perform a conversion action. Ball bearings 5 are arranged at a predetermined interval on the separated support portion 2b.
[0009]
The separation support part 2b provided in the floor board 2 is provided in the series corresponding | compatible type | mold corresponding to the conversion support part 2a in series in FIG. Moreover, in FIG. 3, it provides in the parallel corresponding | compatible type corresponding to the conversion support part 2a in parallel.
[0010]
In FIG. 4, the ball bearings 5 are arranged in the one-line system in which the front and rear are largely shifted laterally with respect to the moving direction of the tongrel 4 in FIG. 4. In FIG. 5, it is provided in a two-row system in which the front and rear are two and are slightly shifted laterally. In FIG. 6, it is provided in a two-row system in which the front and rear are three and are slightly shifted laterally. The number of rows may be increased to 3 rows and 4 rows, and the number of ball bearings 5 arranged at the front and rear is not limited to three.
[0011]
The diameter of the ball bearing 5 is selected according to the load because the load that can be withstood by the diameter is determined. When the diameter of the ball bearing 5 must be reduced due to the thickness of the floor board and other conditions, the same load can be endured by increasing the number of ball bearings 5.
[0012]
The bearing surface constituted by the apexes of the ball bearings 5 arranged on the separated bearing portions 2b of the floor plate 2 is set slightly higher than the conversion bearing portion 2a, and is supported by raising when the Tongler 4 is retracted. The How high it is is determined by the position of the tongrail 4, the diameter of the ball bearing, and various other conditions.
[0013]
Referring to FIG. 7 showing an example of the structure of the ball bearing 5 arranged on the separation support portion 2b of the floor plate 2, a bottom seat ball 7 having the same small diameter that is in contact with the hemispherical concave support portion 6a provided on the casing main body 6 is required. A large number of rolling large-diameter balls 8 are accommodated on the bottom ball 7, and the opening 6b of the casing main body 6 is closed by the lid plate 9 to prevent the bottom ball 7 from coming off, and the hole 9a of the lid plate 9 is opened. A part of the rotating large-diameter ball 8 protrudes outward, and an inner diameter 10a contacts the outer surface of the rotating large-diameter ball 8 on the outside of the cover plate 9, so that the rotating large-diameter ball 8 can be rotated freely. 5 is provided with a water-repellent and dust-proof packing that seals as much as possible and does not give rotational resistance, for example, an oil-impregnated felt packing 10. Bo Sealing cover 11 equipped with openings 11a through which Le 8 is mounted, turning the large-diameter ball 8 is a structure for supporting it against the base 4a of the tongue rail 4.
[0014]
In the casing main body 6 of the above embodiment, the flange portion 6c protrudes laterally from the outer periphery of the upper portion, the peripheral edge of the sealing cover 11 is connected to this portion, and the separation bearing portion 2b provided with the ball bearing 5 on the floor plate 2 When the fitting hole 12 is fitted, the portion of the flange portion 6c is in contact with the separation support portion 2b and the entire ball bearing 5 is supported. A drain hole 13 communicating with the hemispherical concave support portion 6 a is opened at the bottom of the casing main body 6.
Needless to say, the ball bearing 5 may be mounted with the bottom surface connected to the separation support 2b provided on the floor plate 2.
[0015]
FIG. 8 is a plan view of the point 14, and the tongrel 4 is rolled by a rolling bar 15. In this illustration, the ball bearings 5 are rolled and arranged on the floor boards 2 of the sleepers 1 and 1 on both sides of the rod 15, but they may be arranged every other or every other sleeper 1.
[0016]
As described above, since the plurality of ball bearings are arranged on the floor plate, the Tongleil moving on this point greatly reduces the frictional resistance with the floor plate. In addition, the point conversion can be smoothly performed with a small operation force as compared with the prior art.
[0017]
Moreover, since it is a ball bearing, the troublesome maintenance of repeating cleaning and replenishment of lubricating oil every day or every few days as in the past can be saved.
[0018]
Further, since a considerable amount of lubricating oil does not stay on the floor board and roadbed, there is no risk of fire.
[0019]
【The invention's effect】
The Tongleil support device at the point of the railroad track of the present invention is as described above, and the Tongleil moving on the plurality of ball bearings arranged on the floor board greatly reduces the frictional resistance with the floor board. As compared with the prior art, the point conversion can be performed smoothly with a small operating force.
[0020]
Further, since it is a ball bearing, the troublesome maintenance of repeating the cleaning and replenishment of the lubricating oil every day or every few days as in the prior art can be saved.
[0021]
Further, since a considerable amount of lubricating oil does not stay on the floor board and roadbed, there is no risk of fire.
[0022]
In addition, the ball bearings that are arranged at the front and back with respect to the direction of movement of the Tongrel are arranged so as to be shifted laterally with respect to each other. It is.
[0023]
In addition, the ball bearings can be arranged in multiple rows, and the bearing point can be set to 2 or more, and the diameter of the ball bearing can be made smaller than when it is supported at one point. There is an effect that the fitting hole can be fitted and installed. Even if the tongrel becomes heavy, the same ball bearing can be used.
[0024]
In addition, when the ball bearing placement part is provided on the floor plate in parallel with the conversion bearing part that supports the Tongrel, the bearing point of the ball bearing can be moved as close as possible to the conversion support part. As soon as it moves, it can be put on the ball bearing, the frictional resistance is reduced, and the retraction movement of the Tongrel can be performed smoothly with a small operating force.
