Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a Tongleil support device at a point of a railway track.
[0002]
[Prior art]
Conventionally, in this type of Tongleil support device at the point of a railway track, the Tongleil is slidably supported on a steel floor plate having a required area. In order to reduce the frictional resistance with the Tongrel, lubricating oil is applied to the surface.
[0003]
[Problems to be solved by the invention]
The above-mentioned conventional iron floor board needs to be cleaned and replenished with lubricating oil every day or every few days, and the lubricating oil must be sufficiently arranged on the surface, which requires a lot of labor for maintenance work. It is.
[0004]
Further, since the lubricating oil is applied to the floor board and is exposed, a fire may easily occur and a fire may occur.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
At the point where the base rail that lays the floor board on the sleepers and is fixed on the floor board and the Tongler that moves toward and away from the basic rail are placed in pairs, the floor board is at the position where the Tongler is in contact with the basic rail. The reversing bearing portion to be supported and the separation bearing portion in which the tongrel is retracted away from the basic rail, and a part of the separation bearing portion is recessed from the upper surface of the floor plate and provided on the saddle receiving surface. the receiving surface, three bearing mounting hole with respect to the tongue rail, and opening up and down at a required interval, and press fit the body of the casing body of the ball bearing, spaced bearing the flange portion of the casings principalト ン Tongleil support device at the point of the railway track, which is connected to the bearing surface and has three ball bearings.
[0007]
【Example】
Explaining the drawings a bearing apparatus of the tongue rail is a real施例in railway track points of the present invention, as shown in FIGS. 1 and 2, laid floorboard 2 on sleepers 1, on the floor 2 A basic rail 3 fixed to the base 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 supports the Tongrel at a retracted position away from the basic rail 3. A part of the separation support part 2b is recessed from the upper surface of the floor plate in the moving direction of the Tongrel 4 to provide a collar receiving surface 2c, and a bearing mounting hole for the Tongrel 4 on the collar receiving surface 2c. 2d is opened up and down at a required interval of 1 or 2 or more, the body 6a of the casing main body 6 of the ball bearing 5 is press-fitted into the bearing mounting hole 2d, and the flange 6b of the casing main body 6 of the ball bearing 5 is separated. One or two or more ball bearings 5 are arranged so as to be connected to the flange receiving surface 2c of the support portion 2b.
[0009]
Referring to FIG. 3 showing an example of the structure of the ball bearing 5 arranged on the separation support portion 2b of the floor plate 2, the bottom ball 7 having the same small diameter that is in contact with the hemispherical concave support portion 6c provided in the casing main body 6 is provided. A required number of balls are disposed, and a rotating large-diameter ball 8 is accommodated and disposed on the bottom seat ball 7. A part of the ball protrudes upward from the sealing hole 6d of the casing main body 6, and the rotating large-diameter ball 8 serves as a bearing surface.
[0010]
Before you施例floorboard 2, as shown in FIGS. 1 and 2, engagement edge 9 of the base rail 3 toward the center, the oblique engaging grooves 10 respectively provided on the opposite outer edge, the engagement edge As shown in FIG. 2 , a base rail fixing support portion 11 is provided between 9 and the hypotenuse engaging groove 10, and a bolt support hole 12 penetrating vertically to the hypotenuse engaging groove 10 is provided. Is engaged with the hypotenuse engaging groove 10 and the lower end thereof is clamped and pressed by a bolt 15 and a nut 15 supported by a bolt support hole 12 by a rail press 13 having a tip connected to the basic rail 3. Mounting holes 16, 16, 16 are provided at the outer ends, and the mounting holes 17, 17, 17 are provided so as to be freely mounted on the sleepers 1.
[0011]
When the ball bearing 5 is fitted in the bearing mounting hole 2d provided in the flange receiving surface 2c of the spaced support portion 2b of the floor plate 2, the portion of the flange portion 6b is in contact with the flange receiving surface 2c of the separate support portion 2b. The whole of 5 is supported.
[0012]
In this floor board 2, the structure for fixing the basic rail 3 is not limited to the above-described embodiment, and various fixing structures different from the above-described embodiment in terms of details can be proposed.
[0013]
The bearing surface constituted by each apex of the ball bearing 5 arranged on the bearing surface 2c of the separated bearing part 2b of the floor plate 2 is set slightly higher than the conversion bearing part 2a, and when the Tongle rail 4 is retracted, Ascended and supported. How high it is is determined by the position of the tongrail 4, the diameter of the ball bearing, and various other conditions.
[0014]
FIG. 4 is a plan view of the point 18, and the tongrel 4 is rolled by a rolling bar 19. In this illustration, the ball bearings 5 are arranged on the floorboards 2 on the sleepers 1 and 1 on both sides of the rod 19, but they may be placed on every other or on every other sleeper 1. .
[0015]
【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.
[0016]
Further, 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 prior art can be saved.
[0017]
Further, since a considerable amount of lubricating oil does not stay on the floor board and the roadbed, there is no risk of fire.
[0018]
As mentioned above, 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 arranged in pairs, bears at a position in contact with the turning support portion, the tongue rail is formed from release隔支Seung unit you retreat away the basic rails, flange portions of spaced bearing by recessed from the upper surface of the floor plate receiving surface And a bearing mounting hole is vertically opened at a required interval with respect to the Tongrel on the flange receiving surface, and a body portion of the ball bearing casing main body is press-fitted. parts and connected to the separation bearing flange receiving surface, because by disposing one or two or more ball bearings, by finishing the small area of the upper surface of the floor plate, achieving reduction in manufacturing cost, And one in which it is possible to accurately set the arrangement position and height of the ball bearing according to the position floorboards are arranged.
