Description

[Detailed explanation of the idea] The present invention relates to a running track for a freight car moving device.

The running path for the freight car moving device in the conventional freight car yard is the first one.
It is configured as shown in the figure.

That is, the guide rails 1 are L-shaped and are arranged symmetrically inside the freight car rail R, and the traveling wheels of the freight car moving device run on the upper surface of the guide rails, and the guide wheels run on the sides thereof.

Further, the side surface of the guide rail 1 also serves as a surface against which a brake shoe of a mechanical brake device installed in the freight car moving device is pressed.

The left and right guide rails 1 are connected by horizontal beams 2 arranged at each sleeper pitch.

A reaction rail 3, which is a secondary conductor of the linear motor, is arranged in the center of the two guide rails 1, and the reaction rail 3 also serves as a running surface for the linear motor support wheels.

Trolley bars 4 that supply power to the freight car moving device are arranged back to back inside the guide rail 1 with an insulating cover 5 interposed therebetween, forming a running path.

The running path is made up of approximately 10,771 units due to manufacturing, transportation, installation, and removal considerations.

The freight car moving device consists of left and right trolley bars 4 and guide rails 1.
Therefore, a three-phase power source is obtained, and the side surface of the guide rail 1 also serves as a sliding surface for the collector plate.

Conventional running routes, such as those on the ground, were formed by welding the guide rails 1 and reaction rails 3 to the horizontal beams 2 placed at each sleeper pitch, so the horizontal beams 2 and 2 at the time of on-site installation were In order to avoid interference with the sleepers, it was not possible to install all the cross beams in advance, so we installed temporarily assembled ones with cross beams 2 attached at both ends and around the center of the running track unit, and other The horizontal beams had to be aligned and installed on site.

The reason why the horizontal beams 2 are arranged in detail at almost every sleeper pitch is to ensure strength.The center of the horizontal beams 2 receives a lifting force due to the suction force of the linear motor, and furthermore, both ends of the horizontal beams 2 are lifted up by the braking force. receives a force in the direction of lifting up,
This is to prevent the running path from deforming (deflection and stress of the horizontal beam 2).

This makes on-site construction work complicated.

That is, the cross beams 2 are placed between the sleepers in advance, and after the temporary assembly unit is placed, temporary welding is performed to position the cross beams 2, and the actual welding is performed while restraining deformation due to welding.

However, even if the deformation is restrained by welding, the deformation cannot be completely corrected, and correction work such as hydraulic jacking is performed.

Welding areas are also being descaled and repainted.

Since the trolley bar 4 and the insulating cover 5 can only be assembled after the above-mentioned welding work is completed, the entire on-site construction process depends on the progress of this welding work.

Also, welding work has to be canceled in case of rain.

As described above, in the method of attaching the crossbeams 2 at almost every sleeper pitch, a considerable amount of time is wasted in terms of personnel allocation and construction process.

The purpose of the present invention is to eliminate these drawbacks of the conventional technology, to save labor during on-site construction, that is, to reduce the number of workers and shorten the construction period, and to provide a running road with stable quality. A guide rail is provided inside the freight car rail for the freight car moving device, and a reaction rail is located between the guide rails and serves as the secondary conductor of the linear motor and the running surface of the support wheels of the linear motor. In a running track for a freight car moving device consisting of the reaction rail and a trolley bar for power supply provided between the reaction rail and the guide rail, a bed board having a width that almost fills the width of the rail is placed on the sleeper on the inside of the freight car rail. The present invention is characterized in that the guide rail, the reaction rail, and the trolley bar are integrally arranged on the bottom plate, and the bottom plate is locked on the sleeper together with the freight car rail.

An embodiment of the present invention will be described in detail with reference to the drawings.

Figure 2 is a plan view showing the mounting structure of the running path;
Figures 4 and 5 are A-A and B of Figure 2, respectively.
-B and CC sectional views.

From the viewpoint of manufacturing and maintenance such as transportation, installation, and removal, it is preferable that the running path be formed into a unit with a length of about 10 m.

The guide rail 1 and the reaction rail 3 are integrally fixed by welding to a bottom plate 6 provided over the entire length of the unit.

This bottom plate 6 is provided with appropriate drainage holes a on both sides of the reaction rail 3.

The bottom plate 6 can also be subdivided into pieces of less than 1 m depending on manufacturing (handling and equipment) considerations such as rust removal, anti-rust painting, and assembly welding.

In this case, by providing a gap between the joints of the bottom plate 6, there is no need to separately provide a drainage hole.

However, in order to ensure that the wire will always rest on the sleeper when it is laid, this gap should be at most 1/2 or less of the sleeper width.

The bottom plate 6 is installed near the joint and in the middle of each unit so that the positioning stopper 7, which is used to ensure correct lateral centering between the freight car rail R and the running track, is in close contact with the side surface of the lower flange of the freight car rail H. Fixed on top.

A gap is provided at the joint of each unit, and a gap retaining fitting 8 is attached to prevent this gap from expanding beyond the window.

That is, the protrusion C provided at the tip of the gap retaining fitting 8 fits into the notch provided in the bottom plate 6 at the joint of each unit, so that the gap between the running path units does not widen beyond a certain level. .

Here, instead of providing a notch in the bottom plate 6, the gap retaining metal fitting 8 may be formed into a U-shape, and a protrusion may be projected from the bottom plate 6 side to the inside of the U-shape for engagement.

The joint portion and intermediate portion of the traveling path unit are fastened to the freight car rail R by a lifting prevention clamp 9 having a spring action in order to prevent vertical movement rattling and lifting.

At the joint part, a mounting beam 10 is passed under the floor plate 6, and the mounting beam 10, the gap retaining metal fitting 8, the floating prevention clamp 9, and the height adjustment liner 11 are fastened to the freight car rail R by a rail clamp 12.

This fastening part is caused by deformation such as warping or bulging of sleeper members, or local "sagging" of the lower surface of the freight car rail R, etc. When the lower surface of the freight car rail R is taken as a reference, the lower surface of the running road, in other words, the bottom plate 6. Although the upper surface is uneven, it is constructed so that it can sufficiently handle vibrations caused by this unevenness and the passing of freight cars.

That is, the lifting prevention clamp 9 is made of spring steel, and this clamp 9 is made of spring steel.
A liner 11 is inserted between the rails R and the rail R of the freight car to ensure a spring action span, and the top surface of the bottom plate 6 is pressed down with the tip of the lifting prevention clamp 9.

In the future, if there is a local "sag" of the sleeper on the lower surface of the freight car rail R, and the freight car rail R sinks, and the deflection (stress) of the lifting prevention clamp 9 becomes large, the liner 11 corresponding to the "sag" The thickness of the liner 11 is selected so that the spring action of the floating prevention clamp 9 can be ensured even if the liner 11 is removed.

Pass the mounting beam 10 under the bottom plate 6 and attach the rail clamp 12.
The reason why the rail clamp 12 is aligned with the rail clamp 12 is to prevent it from being pushed outward at the slope of the lower flange of the freight car rail R when it is tightened, and to prevent it from coming off due to vibration.

The fastening part is designed to be able to slide even when the rails of the freight car or the running track expand and contract due to the influence of heat.

The intermediate portion of the unit is fastened by passing a mounting beam 10 under the floor plate 6 and fastening the mounting beam, anti-floating clamp 9 and liner 11 to the freight car rail R using a rail clamp 12, similar to the joint portion.

The length of the trolley parr 4 and the insulating cover 5 is preferably about 5 m in view of maintenance such as bending, twisting, transportation, installation, and removal during manufacturing.

The insulating cover 5 and its joint cover 13 are clamped by a clamp 14
It is attached by bolting to screw holes provided at appropriate pitches on the bottom plate.

When removing the running track unit for regular maintenance such as tamping the track bed, remove the tightening bolts of the rail clamps 12 at the unit joints and intermediate parts, and turn the hooks at the tips of the floating prevention clamps 9 outward. By shifting and removing it, you can remove the entire running track unit.

During installation and removal, it is efficient to use a crane truck that can lift the entire unit.

According to the configuration of the present invention, since there is no interference with sleepers during installation, a complete running track unit can be prepared in advance in the factory, and on-site welding work can be almost eliminated.

Therefore, stable dimensional accuracy can be obtained, and the intended purpose of labor saving in installation work (reducing the number of construction workers and shortening the construction period) can be achieved.

In addition, the inside of the freight car track is completely covered with a bed plate, which prevents gravel from flying up onto the running track.Furthermore, in the case of track repair (compaction of the track bed), when the running track is removed and reinstalled. Since there is no part that protrudes below the surface of the sleeper, it does not hit gravel and has the advantage of being easy to assemble.

As shown in FIG. 6, instead of the L-shaped guide rail, a flat plate 15 may be welded perpendicularly to the bottom plate 6, or a special type steel integrally rolled may be used.

In this case, for strength reasons, it is better to make the floor plate one unit long and not to subdivide it.
