Description

  The present invention relates to a railway rail loading / unloading device that is attached to a floor surface of a rail vehicle or in the vicinity thereof so that the rail can be unloaded from the rail vehicle at a rail base or a rail exchange site.

  A rail is a typical consumable part on a railroad track, and in particular, the outer rail of a curve is the most conspicuous and needs to be replaced every predetermined period or every predetermined amount of wear. The railway line is provided with a rail base such as a rail center that manages rails at appropriate locations along the railway line, accepting new rails and processing old rails that have been removed. New rails are transported from domestic steelworks to this rail base by a dedicated wagon, but transportation between the rail base and the rail exchange site is carried out by a self-propelled or locomotive towed rail transport vehicle. The rail transport vehicle shown in Patent Document 1 is a lidless wagon with a total length of 18 m.

  Since there are regular rails and long rails as railroad rails, an appropriate number of lidless wagons are connected in accordance with the length of the rail to be transported when such a lidless wagon is used. There is also a two-car-coupled self-propelled rail carriage designed specifically for 25m fixed rail transportation. If it is a self-propelled type driven by a diesel engine, it can correspond to all routes regardless of electrified sections and non- electrified sections. In any case, however, the rail vehicle itself usually does not have a loading / unloading function. Therefore, in order to load and unload rails at the rail replacement work site, the necessary number of rails at the appropriate base close to the rail replacement site. It is necessary to transfer the vehicle from the rail transporter to the unloading cart having the unloading function and transport it to the work site.

  An example of a rail loading / unloading cart used conventionally is shown in FIG. The loading / unloading cart L shown here is a flat small wagon equipped with traveling wheels 91 and a connector 92. A turntable 93 that is rotatable is provided on the carriage floor 90, and a simple unloading device 97 that includes a post 94 and a girder 95 at one end thereof and a lifting machine 96 such as a chain block is mounted on the girder 95. is there. When transporting the rails to the exchange site, several of the unloading carts L are connected according to the length of the rails, and a plurality of rails are arranged on the turntable 93 across the unloading carts L, and further stacked. In this state, the unloading cart L is pulled to the rail exchange site by a locomotive or the like. The reason why the turntable 93 is provided is to cope with a case where there is a curve or the like on the line being transported.

  If the rails on both the left and right sides of one track are to be exchanged simultaneously, two rails will be lowered to the ground at the rail exchange site where they arrive. In the case of a 25 m fixed rail, the weight of one rail is 1.5 tons if it is a 60 kilo rail. In order to lower the rail to the ground, in general, a guide member is stood diagonally between the side of the carriage and the ground, and the rail slides along the guide member while gradually loosening the unloader lifting the rail. Has been done.

  As a technique for lowering the long rail to the ground, Patent Document 2 describes a technique in which a winch is provided in the rail transport vehicle, and the rail is continuously lowered to the ground while slowly moving the freight car using the guide member as a guide. Yes.

JP-A-10-129479 JP 2000-110102 A

  When the loading cart L described in Patent Document 1 is used to lower the rail to the replacement site, the loading cart 97 has a post 94 on one side of the loading cart L, so the side without the post 94 is provided. The rail can only be lowered. Therefore, for the time being, both rails are lowered to one side of the track, then the unloading cart L is moved by the length of the rails, and the two rails are lowered again at the next position. I have to go down the rails one by one. In order to place one new rail on each side of the track, one of the two rails, which are called Yamakoshi, is installed in a gate shape that spans both sides of the track. It is necessary to lift the rail again with a chain block and move it to the opposite side. In this way, preparation for rail replacement is completed. In addition, when loading the old rail removed after rail exchange on a trolley | bogie, the above procedure will be performed reversely.

  In this way, to put one new rail on each outside of the rail at the replacement place, it takes time and effort to transfer the rail from the rail transporter to the rail unloading cart L, and to move the rail by local Yamakoshi Will be applied. On the other hand, since work at the exchange site is allowed only for a limited time from the last train to the first train, the amount of work per time is limited. For this reason, the actual situation is that it takes a lot of days as a whole.

  The technique described in Patent Document 2 is a technique related to a long rail, and the technique for efficiently loading and transporting a fixed rail such as 25 m is not disclosed in Patent Document 2.

  An object of the present invention is to provide a railway rail unloading apparatus that can greatly improve the efficiency of the entire rail unloading operation.

  The present invention according to claim 1 is a base plate attached to a flat floor surface of a rail transport vehicle, and an end portion of the base plate located on a floor surface side edge side in the rail transport vehicle with respect to the floor surface. The post is attached so that the posture can be changed between the standing state and the state of falling down along the floor surface, and the top of the post can be bent in the extension direction of the post and the direction perpendicular to the post. A railway rail unloading apparatus comprising: an attached girder; and an elevating unit attached to the girder so as to be movable in a length direction of the girder and capable of lifting and hanging the rail.

  The present invention according to claim 2 is the girder in which the two posts, to which the girder is attached to the top, are bent at right angles to the posts at left and right side edges of the floor surface. Is mounted so as to face the center side of the floor surface.

  The present invention described in claim 3 is the railway rail loading / unloading apparatus according to claim 1 or 2, wherein the lifting unit can be fixed so as not to move with respect to the girder.

  According to the present invention, by adding a loading / unloading function to the rail vehicle, it is possible to eliminate the re-loading of the rail between the rail vehicle and another appropriate carriage, and the rails are loaded on both sides of the track. Since it can be wholesaled, it is not necessary to move the rail using the Yamakoshi device, which has been necessary in the past, and the loading and unloading work of the old and new rails is greatly improved in efficiency.

It is explanatory drawing explaining the undulation state of the railway rail unloading apparatus of FIG. It is a partial side view which shows the periphery of a universal joint in the 1st Example of the railway rail unloading apparatus of this invention. It is a perspective view which shows the 2nd Example of the railway rail unloading apparatus of this invention. It is explanatory drawing which shows the use condition of the railway rail unloading apparatus of this invention. It is a perspective view which shows the conventionally well-known railcar loading / unloading cart.

  Embodiments of the present invention will be described below in detail with reference to the drawings.

(Example 1)
FIG. 1 is a perspective view showing a first embodiment of a railway rail unloading apparatus according to the present invention. This unloading device 1 is fixed to a flat floor surface D of a rail transport vehicle T as shown in FIG. A base plate 2 and a pair of posts 4 attached to both ends thereof, that is, side edges of the floor surface D of the rail transport vehicle T, standing upright in the vertical direction via the base side hinge 3 and freely inverting in the horizontal direction, A girder 7 is provided at the top of the post 4 and can be bent in a direction perpendicular to the extension direction of the post 4 and attached in a horizontal direction in a standing state. In the state where the post 4 is standing, an elevating unit 8 that can traverse in the length direction of the girder 7 is attached to the girder 7. The lifting / lowering unit 8 includes a lifting machine such as a chain block. The lifting / lowering unit 8 may be attachable / detachable to / from the girder 7 and is configured to be fixed so as not to move at an arbitrary position of the girder 7. Therefore, a heavy object such as a rail is lifted by the lifting / lowering unit 8 at an arbitrary position of the girder 7 and the lifting / lowering unit 8 is moved in the length direction of the girder 7 in that state, and then the lifting / lowering unit 8 is fixed at an arbitrary position. This heavy object can be hung.

  In this embodiment, the base plate 2 is fixed to an outer edge portion of the floor surface D that does not interfere with the loading of the rails, an upper portion of a side plate that is a stiffening member (indicated by F in FIG. 5), and the like.

  The rail R is suspended from the two-rail-connected rail transport vehicle T stopped at the rail loading / unloading site by the railway rail unloading device 1 of the present invention attached to the side edge of the rail transport vehicle T. The situation is shown in FIG. A new rail to be replaced is loaded on the floor D of the two-car connected self-propelled rail vehicle T. One of them is taken down here. Reference sign G is a guide member that is erected from the ground beside the rail toward the rail transport vehicle T. When the lifting machine of the lifting unit 8 is loosened, the rail R slides diagonally along this. It should be noted that the tip of the girder 7 protrudes outside the vehicle limit when in use during work. After the work is completed, the girder 7 is folded as shown in FIG. 2 to be described later, and the post 4 is tilted and accommodated within the vehicle limit, so there is no problem.

  As can be seen from FIG. 5, it is possible to lift and suspend only the one side of the track on which the rail transport vehicle T is stopped and the side where the post 4 is not present.

  Therefore, in the present invention, the railway rail loading / unloading device 1 is attached in two pairs, facing both ends of the base plate 2 fixed in the direction of the sleeper C near the floor surface of the rail transport vehicle T. Both can be used. For the unloading / unloading device 1, as shown in FIG. 1, the post 4 is tilted horizontally as indicated by an arrow a, and the girder 7 is extended in the direction indicated by an arrow b, that is, in the rail direction (rail). The same floor surface D as the base plate 2 can be laid in a horizontal state (toward the same direction as the rail of the track on which the transport vehicle is stopped). In this case, the unloading / unloading device 1 on the side that is not used is as if it is the rail R loaded on the rail transport vehicle T, and the rail R to be loaded can freely pass over it. By using any one of the pair of two unloading devices 1, the rail can be unloaded on either side of the track.

  FIG. 2 is an explanatory view for explaining the configuration of the post 4 and its undulations in the unloading apparatus 1 of FIG. The post 4 is composed of two plate-like members 4a and 4b, each of which is pin-coupled with the base plate 2 and the base-side hinges 3a and 3b, and the tip side is pin-coupled with the universal joint 6 with the tip-side hinges 5a and 5b. It forms a parallelogram link. Therefore, even if the post is tilted, the universal joint 6 moves up and down in the same posture without tilting.

  FIG. 3 is a partial side view showing the periphery of the universal joint in this embodiment. A universal joint 6 having a U-shaped cross section is supported by a tip hinge 5 at the upper end of the post 4. A vertical pin 61 is fitted at the center position, and the girder 7 is swingably supported around the vertical pin 61. When loading and unloading rails, use the girder 7 with the sleeper C direction.

  By the way, as described above, the curve portion of the track is heavily worn by the rail, so the frequency of rail replacement is high. That is, the rail transport vehicle T often stops at a curved portion and loads and unloads rails. The rail of the curved section is provided with an inclination called “Kant” that makes the outer gauge higher than the inner gauge in order to reduce the centrifugal force of the passing train, so the rail transport vehicle T stops in an inclined state. ing. Therefore, the post 4 is also inclined at the same angle, and the girder 7 is not horizontal. If the minimum radius of the curve is 300 m in the conventional line gauge of 1067 mm, the cant amount is about 105 mm and the inclination angle is about 6 degrees.

  However, in that state, it is inconvenient for the elevating unit 8 such as a chain block to move laterally, so that the girder 7 can be lifted with respect to the post 4 and the girder 7 is tilted horizontally by the inclination at the position, Alternatively, it is preferable to provide a brake or the like that can be fixed at an arbitrary position of the girder 7 on the lifting unit 8 attached to the girder 7. Although not particularly shown in this embodiment, the lifting unit 8 is moved laterally by chain drive, and the lifting unit is prevented from moving from the stop position if the rotary motor is stopped.

(Example 2)
A second embodiment will be described with reference to FIG. In FIG. 4, the lifting unit 8 is omitted. Compared to the first embodiment, the post 4 is not a two-plate but an integral column, and the base side hinge 3 is also a simple hinge. The universal joint is directly attached to the upper end of the post 4 and does not have the above-described tip hinge. The girder 7 is attached to the universal joint 6 with a horizontal pin 68 instead of a vertical pin, and the direction is fixed in the direction of the sleeper C. When not in use, the post 4 is tilted as shown by the arrow c, and the girder 7 bent at 90 degrees is extended as shown by the arrow d so as to be laid straight with the post 4. In the case of an electrified section, care must be taken so that the tip of the girder 7 does not exceed the vehicle limit and come into contact with the overhead wire during the extension process. The effect of laying down is the same as in the first embodiment.

  As described above, the railway rail unloading apparatus according to the present invention does not hinder the loading and unloading of the rail R when it can be raised and lowered with respect to the floor D of the rail transport vehicle T and is not used. Therefore, it is possible to use only one of them on the left and right side edge portions of the rail transport vehicle T, and use only one of them. Since it is defeated, rails can be loaded and unloaded on either side of the track as needed.

  In addition, when the post and the girder are tilted, in the present invention, the girder is bent 90 degrees with respect to the post to make the post and girder straight, but the girder is bent 180 degrees and completely folded, However, there is a problem in pulling the girder with the lifting unit attached, and since it is a lifting equipment, the strength of each structural member and hinge part must be sufficiently guaranteed. In addition, somewhat complicated handling that must be done manually is disadvantageous from the viewpoint of automating the work.

  The rail rail loading and unloading device of the present invention can be easily automated by raising and lowering the posts and extending the girders by providing a hydraulic unit in the rail transporter, thereby further improving the efficiency of rail replacement work. It is.
