DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a standard-size rail stowage apparatus provided in a standard-size rail transport vehicle.

[0002]

2. Description of the Related Art Conventionally, the length used for a conventional line is 25 m.
As a vehicle that transports fixed-length rails to rail replacement points,
For example, as shown in FIG. 8, a fastening wheel 1 having a fastening device 4 for fastening the fixed-length rail 7 to the center of the loading platform, and a guide device 5 for restricting movement of the fixed-length rail 7 in the width direction at the center of the loading platform. The guide vehicle 2 provided is connected, and a slide device 6 is provided on the center of each truck. The fastening device 4 and the guide device 5, which are stacking devices for the fixed-size rail, are provided on a turntable 11 that can rotate with respect to the loading platform. The fixed-size rail 7 is connected to the fastening device 4 in the traveling direction of the vehicle. In the width direction, and is restricted from moving in the width direction by the fastening device 4 and the guide device 5.

[0003] That is, as shown in FIG.
Two columns 12 are erected on the turntable 11, the upper portions of which are connected by a column tensioner 13, the fixed-size rails 7 are arranged side by side through a splint 16, and the columns 12 are fixed between the columns 12. The presser foot 15 is pressed by a plurality of tightening screws 18 via the fastener 14 and fastened. In the width direction, a splint 17 is interposed between the support 12 and the fixed-length rail 7 and fixed. Reference numeral 19 denotes a wire for preventing the screw from being loosened.

The fixed-size rail 7 is 60 kg, 50 kg
There are various sizes such as N and 40 kgN, and there are also used rails that have been removed by rail replacement, so that the rails have various cross-sectional shapes and dimensions. Also, the amount of the fixed-length rails 7 to be transported is different each time and is not constant.

[0005] When stacking the fixed-length rails 7 on a transport vehicle, the same-sized rails are arranged in the same step so that they are securely fastened to each rail. When a large number of standard rails 7 are transported, the standard rails 7 are arranged side by side as shown in the lower part of FIG. When the fixed-size rails 7 to be transported are small, as shown in FIG.
The lateral direction is fixed with a long splint 17 between the 2 and the fixed-length rail 7.

[0006] The structure of the guide device 5 includes a column tensioner 13, which is a component to be fastened from above by the fastening device 4 of FIG.
In this state, the clamp 14, the presser 15, and the screw 18 are removed. That is, the configuration is such that only two columns 12 are erected on the turntable 11.

[0007]

As shown in FIG. 9 (a), during transportation of a fixed-length rail, the carriages of the fastening wheel 1 and the guide wheel 2 rotate about the turntable during curve running, and are fixed. It is desirable that the measure rail 7 be maintained in a straight line.

[0008] However, in the above-described conventional loading device for a fixed-length rail transport vehicle, it is difficult for the turntable to rotate smoothly during curve running.
There is a strong tendency to be in a curved state as shown in FIG. Therefore, the rigidity of the fixed-length rail (reaction force to make it linear)
Therefore, there is a problem that the lateral pressure of the wheel on the track is large. In addition, it is difficult to keep the fastening force constant because the fastening of the standard rail is performed manually with a pressing bolt, and it is used to prevent the beam, tensioning fixture between columns, and pressing bolt from rotating every time the standard rail is loaded / unloaded. Wires and pillars on the wholesale side of rails must be attached and detached.Also, depending on the type and number of standard rails to be loaded, it is necessary to prepare a splint of appropriate length corresponding to each type. Not only loading and unloading, but also preparation requires a lot of time.

In view of the above, the present invention provides a loading device for a fixed-length rail transport vehicle in which a turntable of a fastening device and a guide device rotates in response to a curved running, and a lateral pressure of a wheel on a track is small. It is another object of the present invention to provide a stapling apparatus for a stabilizing rail transport vehicle, in which the stapling force of the stabilizing rail is constant and stowage can be easily performed.

[0010]

The present invention employs the following means to achieve the above object. In other words, a fastening vehicle equipped with a fastening device for fastening the fixed-length rail to the turntable in the center of the bed from above and restricting the movement in the width direction, and moving the fixed-length rail to the turntable in the center of the bed in the width direction. In a loading device for a fixed-length rail transport vehicle connected to a guide vehicle having a guide device for regulating, the fixed-length rail transport vehicle is displaced from the center of rotation of the turntable in the longitudinal direction of the vehicle to the turntable of the fastening wheel and the guide wheel. It is characterized in that side fastening columns for restricting movement in the width direction are provided.

The present invention is characterized in that lateral fastening columns for restricting the movement of the fixed-size rail in the width direction are provided on the turntables of the fastening wheel and the guide wheel so as to be shifted from the center of rotation of the turntable in the longitudinal direction of the vehicle. And For example, assuming that the side fastening columns are provided offset from the center of rotation of the turntable in the longitudinal direction of the vehicle by L (mm), a moment of rotating the turntable FL acts when the fixed-size rail transport vehicle travels on a curve. Here, F is a reaction force due to the loaded standard-size rail. Therefore, the turntable is smoothly rotated by the above moment during the curve running, so that the fixed-length rail is easily maintained in a straight line, and the lateral pressure of the wheel on the track can be greatly reduced.

When the movement of the standard rail in the width direction is directly controlled by the lateral fastening columns, the lateral fastening columns can be moved in the vehicle width direction, and the lateral fastening columns are pressed against the standard rail from both sides. The side fastening column can be detachably attached to the turntable at a plurality of positions in the vehicle width direction, and the fixed rail is pressed against the side fastening column as described in claim 2. Bolts should be provided. By doing so, it is possible to cope with a case where a small number of fixed-length rails are transported, and it is possible to sufficiently fix the fixed-length rails in the width direction.

Further, it is required that the work for stacking the standard-length rails be performed efficiently. However, the main body having the fastening device erected on both edges of the turntable as described in claim 3 is provided. A swing arm for detachably connecting the upper end of the main column; a swing beam for fastening the fixed-length rail by a coil spring to the swing arm; and connecting the swing arm and the swing beam by a cylinder operated by a manual pump. In this case, fastening and release of the fixed-length rail can be easily performed. The fixed-length rail can be easily and securely fastened by interposing an elastic body such as a rubber plate between the holding rail and the holding beam. Further, in order to cope with the type and the stacking of the standard rails, an upper / lower step switching mechanism and a height adjusting bolt are provided on the holding beam, so that the standard rails are fastened to thereby improve workability.

Is provided with a turntable 41, and two main columns 42 are fixed to the turntable 41 so as to face each other. In addition, the height of the main pillar 42 is higher than the height of the stacked standard-sized rails 7 so that the loaded standard-sized rails 7 do not protrude from the loading platform of the vehicle even if the load collapses. I have.

The rotating table 41 has the fastening device 4
Similarly, side fastening columns 43 are provided at a distance L from the main columns 42. The side fastening columns 43 are fixed to the mounting portions 45 of the turntable 41 with bolts 43a. The mounting portion 45 has a plurality of mounting holes 45 so as to be fixed at appropriate positions in the width direction.
