Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor plate for a turnout in which a tongue rail sliding portion is provided on a floor plate body adjacent to a basic rail.

Since the tongue rail slides on a sliding plate and converts between normal and reverse positions, the sliding part is coated with oil and oil-impregnated oil-free metal is installed to improve maintainability. are doing.

Conventionally, when installing oil-free metal on a floorboard, an oil-free metal fitting part is formed in the floorboard body, and a sliding part is formed integrally with the floorboard body by fitting the oil-free metal into this fitting part. Ta.

However, with such conventional turnout floorboards, the sliding parts may wear out after long-term use, or the wheels may hit the sliding parts when a vehicle passes over the turnout.
If the impact load causes the sliding part to deform and cause operational problems, and it becomes necessary to replace the sliding part, the sliding part is installed integrally with the floorboard body. Therefore, even though the sliding part is a part of the floorboard body, the entire floorboard body had to be replaced, making the replacement work extensive, increasing work time and cost, and causing great waste.

The present invention has been made in view of these conventional problems, and aims to solve the above problems by making only the sliding part replaceable.

In order to achieve such an objective, the present invention provides a floor plate for a turnout which is provided with a sliding part on which a tongue rail slides on the floor plate body adjacent to the base rail, in which oil-free metal covers one part of the surface. A sliding part is provided on the upper surface of the sliding plate which is separate from the floorboard body, and includes a front stopper on the side close to the basic rail and a sliding part arranged so as to form a part from the front stopper in the direction away from the basic rail. A rear stopper located at a distant position is fixedly arranged on the floorboard body, and a sliding plate is fitted between the front stopper and the rear stopper with the upper surface facing upward, and the positions of both stoppers are perpendicular to each other. A floor plate for a turnout is characterized in that the sliding plate is removably fixed to the floor plate body by bolting fixing flanges protruding on both sides of the sliding plate in the direction, and replacing the sliding part is as follows: This can be done by loosening the bolts, removing the sliding plate, and replacing it.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 to 3 show an embodiment of the present invention, in which a floor plate 1 has a floor plate main body 2 that supports a basic rail A, and a sliding plate 3 on which a tongue rail B slides is removably fixed. It consists of

A support groove 21 is carved in the floorboard body 2, and a basic rail A is fitted into this support groove 21 so as not to be movable in the lateral direction.A front stopper 22 close to the basic rail A and a rear stopper separated 23 are welded and fixed.

The sliding plate 3 has a front stopper 22 and a rear stopper 23.
The central part forms a sliding part 31 on which the tongue rail B is placed and slides. 32, 32... are disposed so as to be embedded from the upper surface and form a part of the surface. Fixing flanges 33, 33 integrally protrude from both sides of the sliding portion 31, and bolt fastening holes 34, 34 are bored in the fixing flanges 33, 33, respectively.

The front stopper 22 is located on the side close to the basic rail A, and the rear stopper 23 is located away from the front stopper 22 in the direction away from the basic rail A, and these are fixedly arranged on the floorboard main body 2. ing.

Then, the front stopper 22 and the rear stopper 23
The sliding plate 3 is fitted between the sliding plate 3 with its upper surface facing up, and the fixing flanges 33, 33 are protruded from both sides of the sliding plate 3 in a direction perpendicular to the positions of both stoppers.

Screw holes 2 correspond to bolt fastening holes 34, 34...
4, 24... are drilled in the floor plate main body 2, and are inserted into the bolt insertion holes 35 and the bolt fastening holes 34 through a rotation prevention plate 36 having bolt insertion holes 35, 35, and the bolts 37 are screwed into the screw holes 24. After the bolts 37 are fastened, the corner portions 38 of the anti-rotation plate 36 are hooked onto the heads of the bolts 37 and bent to prevent rotation, and the sliding plate 3 is fixed.
A tongue rail B is placed on a sliding portion 31 of a sliding plate 3 provided adjacent to the tongue rail B.

In the turnout floor plate having the above configuration, the tongue rail B slides smoothly on the sliding portion 31 of the sliding plate 3 by being lubricated by the oil contained in the oil-free metals 32, 32.

When the sliding part 31 becomes worn out and needs to be replaced, the sliding plate 3 can be removed by flattening the corner part 38 of the anti-rotation plate 36 and then loosening and removing each bolt 37. It is inserted between the front stopper 22 and the rear stopper 23 in place of the sliding plate 3, and the bolt 37 is inserted into the bolt insertion hole 35 of the stopper plate 36 and the bolt fastening hole 3 of the fixing flange 33.
4, screw it into the screw hole 24 of the floorboard body 2 and tighten it, raise the corner part 38 of the stopper plate 36, hook it onto the head of the bolt 37, and bend it to complete the replacement.

According to the floor board for a turnout according to the present invention, the sliding board having the sliding part is removably fixed to the main body of the floor board, and the sliding part can be easily replaced. There is no need to replace everything,
Replacement work becomes easier, requires less work time, reduces costs, and eliminates wasted materials.
