Description

Rail car {GOODS WAGON}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a freight car, and more particularly, to a freight car capable of freely freighting freight on a platform and reducing the interval between freight cars.

A train is a train or locomotive that runs on orbits, usually consisting of one or more railway vehicles that are removable.

Such a vehicle can be divided into a power car, a passenger car, and a freight car to carry the object according to functions. A power car alone or a power train and a coach or a car are combined to suit a purpose to form a single train.

Among them, a freight transport train in which a power car and a plurality of freight cars are combined is becoming a necessity as a means of transport for domestic and foreign trade over time.

A wagon for transporting cargo from such freight transportation trains is generally composed of a bogie having a wheel so that the wagons can run safely on the rails and an upper plate capable of loading cargo above the bogie.

In the case of cargo transportation by the above-mentioned cargo transportation train, it is advantageous that a large amount of cargo can be transported at a small cost compared to other transportation means. However, since the train must be operated on the railway, There is a disadvantage in that a car transportation means is required.

For example, it is necessary to move the cargo from the train to the truck and then to transport the cargo to the area by truck again. For this reason, cargoes are carried between cargo trucks and trucks.

Conventionally, in moving a freight from a freight car to a truck or from a truck to a freight car, a truck for transporting freight in the cargo has not been able to directly access the freight. The truck could only access the side of the train. For this reason, a tower crane has been used to move cargo from train to truck.

However, there are some drawbacks to this approach: the platform is costly and time consuming, and the required length of the platform is equal to or longer than the length of the train.

In the related art, there is a system (Modahor System) that rotates a top plate on which a cargo is loaded so that a truck can directly load and unload the cargo on the platform by hydraulic pressure. This is a method in which only the upper plate on the car is rotated, There is no effect of reduction and there is a problem that a power unit for rotation is separately required.

Nowait Transport, a technology that allows trucks to access freight directly while the platform is rotating, reduces the required length of the platform by shrinking the train accordion-like near the platform, which requires special rails for this purpose. Which is incompatible with ordinary railways.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Brief Description of Drawings FIG. 1 is a block diagram of a computer system according to an embodiment of the present invention; FIG. 2 is a block diagram of a computer system according to an embodiment of the present invention; FIG.

FIG. 1 shows a running state of a railway lorry 100 according to an embodiment of the present invention. FIG. 1 shows a state in which one or more lorries 100 are connected in series. Fig.

1 and 2, a railway wagon 100 according to an embodiment of the present invention includes a main bogie 120 running on a main orbit 10 and a main bogie 120 rotatably connected to the main bogie 120 And a rotatable link 140 connected to the rotatable link 140. The rotatable link 140 rotatably supports the upper plate 110 and the upper plate 110, And the auxiliary truck 130, respectively.

Here, the truck wheels of the main truck 120 and the auxiliary truck 130 are provided so that the truck 100 travels along the main orbit 10, and this is a configuration commonly used in railway vehicles. It is omitted. In addition, the platform means a place where the unloading of the railway wagon 100 is performed, and means a station or a station for stopping.

The main orbit 10 shown in the figure is the same as a generally used railroad in which the weight of the vehicle is supported by the railway line and transmitted to the roadbed, Each of the configurations not described below will be described below.

First, the upper plate 110 performs a function of loading cargo in the wagon 100, and may have a rectangular plate shape as shown in the figure. In the upper plate 110, a latching jaw (not shown) for facilitating the loading of containers and cargo can be formed on the upper sides of both long sides.

In addition, the top plate 110 itself may be in the form of a container. This not only allows a large amount of cargo to be loaded, but also prevents the cargo from falling down the lorry 100 due to the shaking that occurs during operation.

A guide member 150 may be installed on the lower surface of the upper plate 110 to rotate the upper plate 110 around the rotation support portion 120a provided on the main carriage 120 without depending on a separate power source. Such a guide member 150 may have a rod shape as shown in the figure. The detailed shape and role of the guide member 150 will be described later, together with the rotation of the upper plate 110.

Next, the main truck 120 serves as a center for supporting the weight of the upper plate 110 on which the cargo is loaded, and may be connected to the upper plate 110 by the rotary support 120a.

Here, the rotary support 120a may freely rotate the upper plate 110 installed on the upper side, and a connection system using a thrust bearing may be used. This allows the upper plate 110 to be rotated easily while retaining a large load applied along the axis.

The auxiliary truck 130 is supported by the main truck 120 and runs along the main orbit 10 to support the top board 110. The top board support 130a is provided to easily support the top board 110 .

The upper plate supporting part 130a is for supporting the load of the upper plate 110 together with the main bogie 120 while the wagon 100 is loaded on the main orbit 10, So that it can be protruded from the auxiliary truck 130. This ensures that the upper plate 110 is stably supported even though vibration and impact frequently occur in the wagon 100 during operation.

In addition, one or more rollers (not shown) may be installed on the upper plate supporter 130a. This reduces the friction between the upper plate 110 and the upper plate support 130a when the upper plate 110 is rotated so that the upper plate 110 is smoothly rotated.

At this time, one auxiliary truck 130 may be installed to support the upper board 110 together with the main truck 120. Preferably, however, two auxiliary trucks 130, namely, the first auxiliary truck 131 and the second auxiliary truck 130, The auxiliary truck 132 may be disposed on the main trajectory 10 before and after the main truck 120, respectively. The first auxiliary truck 131 and the second auxiliary truck 132 may be connected to the upper plate 110 by the first rotary link 141 and the second rotary link 142, respectively.

As shown in the drawing, two auxiliary trucks 130 and a main truck 120 are disposed in series on the main orbit 10, and two main trucks 130 are disposed in series between the first auxiliary truck 131 and the second auxiliary truck 132, So that the truck 120 is positioned. This allows the cargo held on the upper plate 110 to be stably supported.

The rotary link 140 connects the upper plate 110 and the auxiliary truck 130 so that one end of the rotary link 140 is rotatably connected to the upper plate 110 and the other end of the rotary link 140 is rotatably connected to the auxiliary truck 130 . The auxiliary truck 130 can be pulled toward the main truck 120 when the upper plate 110 is rotated around the rotation supporting portion 120a of the main truck 120. [

At this time, bearings may be inserted into the coupling portions of the rotary link 140, the upper plate 110, the rotary link 140, and the auxiliary bogie 130, respectively. So that rotation can be facilitated.

3 to 6, the guide member 150, which is not described in detail above, and the manner in which the wagon 100 is rotated thereby, and the auxiliary bogie 130 are drawn toward the main bogie 120, ) Is described below.

FIG. 3 is a plan view of the railway lorry 100 according to an embodiment of the present invention when the platform is opened. FIG. 4 is a combined state of the guide member and the guide track. FIG. 5 is a rotational state view of the railway wagon 100. 6 shows a stop state diagram of the railway lorry 100. Fig.

The illustrated guide track 20 is installed separately from the main track 10 for the purpose of implementing the present invention and may be a railroad track having the same sectional shape as the main track 10. However, as shown in the drawing, the guide track 20 is separated from the main orbit 10 starting from a position spaced apart from both sides of the main orbit 10, and is installed on the ground parallel to the main orbit 10, ).

Next, the guide member 150 can perform the role of rotating the upper plate 110 by the two distant guide races 20. The first guide member 151 and the second guide member 152 are brought into contact with the first guide track 21 and the second guide track 22, The vertical force is applied to the upper plate 152 and the rotational force is transmitted to the upper plate 110.

3, the guide member 150 may function as only one of the guide members 150, but it is preferable that the guide member 150 and the first guide member 150 are symmetrically arranged in the diagonal direction of the upper plate 110, 151 and a second guide member 152 may be provided. This causes the upper plate 110, which is loaded with the heavy cargo, to be stably rotated by the guide member 150 provided symmetrically.

The first guide member 151 and the second guide member 152 may also serve to prevent the upper plate 110 from being rotated any further although it also serves to initiate the rotation of the upper plate 110. That is, the rotation range can be adjusted.

For example, the first guide member 151 provided on the front left side may be used to start rotation of the upper plate 110, and the second guide member 152 provided on the rear right side may cause the upper plate 110 to slide due to inertia Thereby preventing the rotation of the rotating shaft from being unnecessarily rotated.

The guide member 150 may also prevent the wagon 100 from further proceeding along the main trajectory 10. So that the wagon 100 arriving at the platform does not go forward for unloading work.

More specifically, the guide members 151 and 152 of the waggon 100 are arranged on the guide rails 22 and 22 so that the distance between the first guide track 21 and the second guide track 22 is longer than the length of the upper plate 110. [ (20) so that it can not proceed further. Which is not shown, but may easily be selected depending on the designer's purpose and environment.

Or the guide member 150 may be formed to protrude above the top plate 110. In this case, the guide trajectory 20 may be spaced apart from the ground, as shown. The guide track 20 is set higher than the upper plate 110 and the guide member 150 is provided so as to correspond to the height. The installation position and the number of the guide members 150 may be somewhat different depending on the design of the wagon 100 and the shape of the guide track 20. [

4, one end of the guide member 150 is connected to the upper plate, and a friction member 153 is further provided on an outer surface of the guide member 150 in contact with the track. Thus, the wagon 100 can have a larger braking force. That is, the friction between the friction member 153 and the guide track 20 serves to brakes the wagon 100 together with the braking device provided in the wagon 100. This increases the stopping speed of the wagon 100 and enables rapid movement of the goods.

One end of the guide member 150 is connected to the upper plate, and the other end of the guide member 150 is provided with a wheel (not shown) to move along the guide line 20. Hereinafter, a method of rotating the upper plate 110 and a process of narrowing the interval between the main bogie 120 and the auxiliary bogie 130 will be described.

The rotation of the upper plate 110 can be performed by the following steps. A rotation start step in which the guide member 150 meets the guide track 20 when approaching the platform, a top plate rotation step in which the guide member 150 rotates the guide plate 150 along the guide track 20, 110 is fully rotated and thus the gap between the main truck 120 and the auxiliary truck 130 is minimized.

The rotation start step is a step in which the outer surface of the guide track 20 and the outer surface of the guide member 150, which are spaced apart from each other as the wagon 100 moves along the main orbit 10, That is, the guide member 150 and the guide track 20 are in contact with each other.

In the upper stage rotating step, the two guide trajectories 21 and 22 installed so as to be gradually distant from each other apply a force to the guide member 150 abutting on the guide track, and this transmits rotational force to the upper plate 110, Is rotated.

The completion of the rotation means a stage in which the upper plate 110 of the wagon 100 is sufficiently rotated by the designed rotation range and can be unloaded by the secondary transportation means or the like. The rotation range of the upper plate 110 is selected by the designer in consideration of the shape and installation position of the guide track 20, the length of the rotation link 140, the shape, size and number of the guide member 150, .

At this time, each of the above-described steps is performed continuously, which greatly shortens the freight transportation time by the wagon 100. Also, in the railway lorry 100 according to the present invention, the upper plate 110 is rotated in the platform, so that the transportation vehicle can directly access the cargo, so that the loading and unloading operation can be performed quickly.

Next, the distance between the main truck 120 and the auxiliary truck 130 is narrowed. This is performed by the rotating link 140 connecting the top board 110 and the auxiliary truck 120.

In detail, when the upper plate 110 is rotated by the above-described method, a force acts on the rotating link 140 connected to the upper plate 110 so that one end of the rotating link 140 is attracted to the upper plate 110, 130 so that the gap between the auxiliary truck 130 and the main truck 120 is narrowed. That is, when the upper plate 110 rotates, the auxiliary rail 130 is drawn toward the main rail 120 by the rotary link 140 so that the interval is narrowed.

FIG. 7 is a view illustrating a state in which a guide member and a guide track are coupled according to another embodiment of the present invention.

Referring to these drawings, various types of guide members 250 and 350 may be installed on a railway car according to another embodiment of the present invention. The guide member 250 may include a roller 251 parallel to the paper surface and contacting both sides of the guide track 20 as shown in (a), and the guide track 250 And a roller 351 contacting only one side surface of the roller 351.
