Abstract

PURPOSE:To improve load efficiency of a freight car so as to surely carry out a load by mounting a bag, which is formed flat when a granule is loaded and inflated by compressed air when the granule is carried out to press out the load to the outside of a transport vehicle, to the inside thereof. CONSTITUTION:Rubber-shaped bag units 5, 6 are provided in both sides of a supporting plate 4, vertically placed in a loading space 3 of a transport vehicle 1, to rotatably support steel plates 7 to an arm 8, extended from the supporting plate 4, in an external surface side of the rubber-shaped bag units 5, 6, and the second steel plates 10 are mounted to point ends of the steel plates 7 through hinge mechanisms 9. In the case of carrying out a load, compressed air is fed into the rubber-shaped bag units 5, 6 inflated to right/left to form a sloped surface A by the steel plate 7, and further the second steel plate 10 is raised up through the hinge mechanism 9 to carry out a granule in the loading space 3 from carry-out doors 2.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport vehicle for loading and transporting powder and granular materials, and mainly relates to a hopper vehicle with improved loading efficiency, which is applied to railroad freight cars (hopper vehicles).

0002

[Prior Art] Conventionally, when transporting particulate materials such as sand, gravel, coal, concrete, etc., a steel plate for resting has been arranged at an angle inside the freight car to facilitate removal after transport. was. FIG. 1 is a schematic diagram showing the inside of this freight car, and in order to make unloading smooth, a resting iron plate 30 is arranged at an angle in the center, and when the unloading door 40 is opened, the loaded items inside can be The iron plates 30 are to be distributed left and right along the inclination and then carried out.

0003

[Problems to be Solved by the Invention] As can be seen from this figure, approximately 1/3 of the interior volume of the freight car is the air space created by the rest iron plate 30. In other words, the loading efficiency deteriorates accordingly, resulting in higher transportation costs per ton of loaded materials.In some cases, because the installation angle of the resting iron plate is fixed, differences in the type and properties of loaded materials may occur. This also caused the problem that it adhered to the rest plate 30 and could not be removed properly. The present invention aims to solve these drawbacks, and provides a structure for a transport vehicle that improves the loading efficiency of a freight car and reliably transports loaded items.

0004

[Means for Solving the Problems] In order to achieve this object, the present invention provides a bag that is flat when loaded with powder and granular materials, but expands with compressed air when being carried out, and reliably pushes the loaded material out of the transport vehicle. This is an attempt to solve this problem by installing it inside the transport vehicle. That is, the gist of the present invention is a transport vehicle equipped with a powder and granular material input port in the ceiling and an unloading door in the lower part of the side plate, which is characterized in that a rubber-like bag that is inflated by compressed air is installed in the loading space. Particularly, the structure of the powder and granular material transport vehicle is such that when the rubber bag is expanded by compressed air, it forms an inclined surface within the loading space. It is something.

[0005]

[Function] The structure of the present invention is as described above, and when loading powder or granular materials into a space, the rubber bag is preferably folded to form a flat plate. On the other hand, when unloading, the rubber bag is inflated with compressed air, and this inflation allows the load to be loaded through the unloading door. A sloping surface is formed so that objects can easily fall, and this makes carrying out more reliable.

[0006]

[Specific Examples] Hereinafter, the transport vehicle of the present invention will be explained in more detail with reference to the drawings. FIG. 2 is a longitudinal cross-sectional view showing a first embodiment of the transport vehicle of the present invention, and FIG. 3 is a diagram showing a state in which the rubber-like bag shown in FIG. 2 is inflated. In the figure, 1 indicates a side plate of a transport vehicle, and 2 indicates an ejection door provided below this side plate 1. 3 is a loading space for the transport vehicle 1, and rubber bags 5 are placed on both sides of a support plate 4 that stands upright in this space 3.
, 6 are provided. On the outer surface side of the rubber bags 5 and 6, a steel plate 7 is pivotally supported by an arm 8 extending from the support plate 4.
A second steel plate 1 is connected to the tip of this steel plate 7 via a hinge mechanism 9.
0 is attached. In addition, the powder/grain material inlet is omitted in the figure.

Now, when carrying out the loaded items, as shown in FIG. 3, compressed air is sent into the rubber bags 5 and 6.
In this case, the steel plate 7 expands left and right with the shaft support of the arm 8 to form an inclined surface A, and this steel plate 7 is further expanded to the second steel plate 1 via the hinge mechanism 9.
0 will also rise with an inclination. Therefore,
The powder and granular materials that were in the loading space can now be reliably carried out through the carrying-out door 2. Particularly in this case, if the loaded object adheres to the steel plate 7 or the like, air can be moved in and out of the rubber bag repeatedly to ensure that it can be carried out. In this example,
In order for the second steel plate 10 to reliably form the inclined surface A toward the carry-out door 2, it is desirable that the second steel plate 10 be placed flat along the bottom surface in the space during loading.

FIG. 4 shows a second view of the powder and granular material loading transport vehicle of the present invention.
As an example, FIG. 5 shows the state when the rubber-like bag is inflated. In this example, the steel plate 7 from the previous example is
, instead of the hinge 9 and the second steel plate 10, a membrane body 11 made of rubber or synthetic resin is placed on the outside of the rubber bags 5 and 6, and the inclined surface B is reliably formed. For this purpose, one end of the membrane body 11 is fixed 12 to the tip of the support plate 4, and the other end is fixed 13 to a corner portion of the loading space 3. Such membrane body 11 should be made of a material with little elasticity.

FIG. 6 shows the third part of the powder and granular material loading transport vehicle of the present invention.
As an example, FIG. 7 shows the state when the rubber-like bag is inflated. In the figure, the rubber bag 14 is folded flat on the bottom surface of the space 3 when loaded with powder and granules, and is inflated by supplying compressed air to the bag when being carried out. In this case, the inclined surface C is the membrane body 11 made of rubber or synthetic resin as in the previous example, and in this example, the supporting plate 4 of the previous example is used.
Instead, one end thereof is fixed 16 to the horizontal beam 15.

FIG. 8 shows a fourth embodiment of the powder transport vehicle of the present invention, and FIG. 9 shows the state when the rubber bag is inflated. In the figure, a rubber-like bag 17 is placed flat on the bottom surface as in the previous example, and a standing plate 18 is formed on this bag 17, and a membrane body 11 forms an inclined surface D with the tip of the standing plate 18. and are fixed19,
When compressed air begins to enter the rubber bag 17, the upright plate 18
naturally moves upward, and the film body 11 forms an inclined surface D.

FIG. 10 shows a fifth embodiment of a powder transport vehicle according to the present invention. In this example, the carry-out door 2 is provided only on one side of the side plate of the transport vehicle, and in this case, the rubber bag-like body 20 is arranged on the opposite side, and the slope E in this example is the first It is formed of a steel plate 21, a hinge 22, and a second steel plate 23 as in the embodiment. Therefore, when the rubber bag 20 is inflated, the inclined surface E is formed only on one side.

[Effects] Because the present invention has the above-described configuration, the loading efficiency is extremely high and transporting can be carried out reliably, reducing transportation costs and requiring less effort during transporting. It is of course used not only for railway freight cars, but also for large automobiles.
