Description

Railway wagons {FREIGHT CAR FOR RAILROAD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to railroad wagons, and more particularly, to railroad wagons provided with a wagon body having a cargo loading section and a side door opening.

In general, railway railcars are provided with a plurality of wheels for traveling a railroad and a freight car body provided with a cargo loading unit for loading freight, and a transverse direction in the longitudinal direction of the main body for loading cargo in the cargo loading unit. And a plurality of doors capable of opening and closing the door openings. Thus, by loading the cargo in the cargo loading through the door opening provided in the main body of the car, by closing the door opening using a plurality of doors, it is possible to transport the cargo safely.

However, such a conventional railroad wagon is generally provided with 12 doors (6 on each side) at the door openings on both sides, and a rail having a double sliding structure under the door opening where the doors are provided. Therefore, when loading or unloading cargo, the doors must be alternately shifted in order to open and close the door openings so that a lot of time and manpower is wasted in loading or unloading cargo.

In addition, the conventional railroad wagon car has a problem in that the door is severely shaken or dislodged by external pressure such as vibration during railroad driving.

Accordingly, an object of the present invention is to provide a railroad car that can easily open and close the door to reduce the time and manpower to load or unload the cargo, as well as to prevent the door shake.

In addition, the pair of lower shifting brackets 56 are integrally coupled to the outer surface of the sliding roller 55 to move the contact by the lower shifting bar 85 to transfer the door 30 to an open ready state or a closed state. It is provided, the holding portion 58 which is supported by the door support 27 when the door 30 is in the closed state at both ends of the sliding roller 55 in the sliding direction is provided.

By such a configuration, as shown in Figures 5 to 9, look at the operation of the door provided in the vehicle for the vehicle according to an embodiment of the present invention as follows.

First, the process in which the door 30 is transferred from the closed state to the ready to open state will be described. 5 is a cross-sectional view of a state in which the door 30 is in a closed state to close the door opening of the vehicle body 10. As shown in this figure, the guide roller 50 is separated from the guide rail 20 is transported in the direction of the main vehicle body 10, the sliding roller 55 is also separated from the lower fixed rail 25 the wagon It is conveyed in the direction of the main body 10, and the holding | maintenance part 58 is put on the support 28 of the door support part 27. As shown in FIG. In addition, the state in which the door 30 is in the closed state is the same state as the shifter driver 100 placed on the right side of FIG. 9. In this state, when the rotary knob 101 of the shifter driver 100 placed on the right side of FIG. 9 is rotated clockwise, when the door 30 is rotated to an open ready state, the upper rod 110 is moved downward and at the same time, the lower rod is rotated. 120 is moved upwards so that the upper shifter body 61 is rotated counterclockwise and the lower shifter body 81 is rotated clockwise. Thus, when the door 30 is transported in an open ready state, the door 30 may have the same shape as the shifter driver 100 placed on the left side of FIG.

6 is a longitudinal sectional view showing a state in which the door 30 is transferred in an open ready state. As shown in this figure, the opening shifting bar 63 integrally provided on the upper shifter body 61 pushes the upper shifting bracket 51 provided on the upper part of the door to the outside to guide the guide roller 50 to the guide rail ( 20). In addition, the shifting rail 83 and the lower auxiliary rail 87 integrally provided at the lower shifter body 81 push the sliding roller 55 and the lower shifting bracket 56 provided at the lower part of the door to the outside to support the door. As the holding part 58 placed on the 27 is moved outward, the sliding roller 55 is transferred to the lower fixing rail 25.

And, as shown in Figure 7, when the door 30 is opened, the guide roller 50 is guided to the guide rail 20 and the sliding roller 55 is guided to the lower fixed rail 25, open The intermediate guide roller 40 provided on the rear surface of the door 30 is accommodated and guided by the intermediate guide rail 45 provided on the outer surface of the door 30 in the closed state (see FIG. 8). And, protruding from the lower end of both sides of the door 30 is provided on the stop bar 37 and both ends of the longitudinal direction of the vehicle body 10 corresponding to the stop bar 37, the sliding movement of the door 30 By providing a stopper 13 to limit the door 30 can be safely moved.

In addition, the process in which the door 30 is moved from the open ready state to the closed state rotates the rotary knob 101 provided in the shifter driver 100 in a direction opposite to the direction in which the door 30 moves to the open ready state. Then, the upper shifter body 61 and the lower shifter body 81 are rotated by the upper rod 110 and the lower rod 120 in the opposite direction to move the door 30 to the open ready state. Then, the closing shifting bar 65 is in contact with the rear surface of the upper shifting bracket 51 to transfer the upper shifting bracket 51 in the direction of the vehicle body 10. Then, the shifting rail 83 and the lower shifting bar 85 transfer the sliding roller 55 and the lower shifting bracket 56 in the vehicle body body 10 direction. Then, the pushing member 88 provided on the lower shifter main body 81 presses the outer surface of the sliding roller 55 so that the holding unit 58 provided on the sliding roller 55 supports the support 28 of the door support 27. Put on top. Thus, the door 30 closes the door opening of the vehicle body 10. And, as shown in Figure 5, the pushing member 88 is the inner side of the outer surface of the sliding roller 55 provided in the lower portion of the door 30 in order to prevent the door 30 in the closed state from shaking or falling off. Is pushing in a continuous direction.

In the above-described embodiment, three upper shifting brackets 51 and a pair of guide rollers 50 spaced a predetermined distance from each of the doors 30 are provided, but one or more of these components may be provided. The opening shifting bar 63 and the closing shifting bar 65 corresponding to the upper shifting bracket 51 are also preferably the same as the quantity of the upper shifting bracket 51. In addition, a pair of sliding rollers 55 and a lower shifting bracket 56 spaced a predetermined distance from the lower portion of each door 30 are provided, but one or more of these components may be provided, and the sliding rollers 55 The shifting rails 83 and the lower shifting bars 85 corresponding to the lower shifting brackets 56 and the lower shifting brackets 56 are also equal to the quantity of the sliding roller 55 and the lower shifting bracket 56. In addition, in the above-described embodiment, the holding unit 58 is provided at both ends of the sliding roller 55, but the holding unit 58 may be provided at one side of the sliding roller 55, and the door support unit 27 may be provided. It may also be provided one by one corresponding to the holding unit 58, of course.

As in the above-described embodiment, the door is preferably made of aluminum, but of course, other materials, such as alloy steel, which is light and maintain strength, may be used.

As such, the railroad car according to the embodiment of the present invention supports a pair of doors provided on both sides of the main body so as to support the doors in a parallel movable manner, and the door is parallel between the closed state and the open ready state spaced outward. A shifting unit for moving, at least one holding unit provided on the door, a door supporting unit provided on the vehicle body for supporting the holding unit when the door is closed by the shifting unit, and a holding unit provided on the shifting unit. By providing a pushing member for pushing the door so as to be supported by the door support, the door can be easily opened and closed, thereby reducing time and manpower for loading cargo. Then, shaking and detachment of the door can be suppressed.

As described above, according to the present invention, the door can be easily opened and closed, so that time and manpower can be reduced to load or unload cargo, and the shaking and detachment of the door can be suppressed.
