Description

[Detailed explanation of the invention] This invention consists of a tank body, a distribution beam spanning approximately at the upper center of the front and rear walls of the tank body,
A pair of left and right rotating shafts provided substantially parallel to the distribution beam and supported at the lower portions of the front and rear walls, and a pair of left and right plates each extending upwardly from these rotating shafts by a predetermined width. The tank is equipped with a rotating body having a shape of a shape, and a bag-shaped movable diaphragm provided in the tank body and having an opening at the bottom for dividing the tank body into a plurality of storage chambers; The present invention relates to a tank in which the volume of the storage chamber can be changed by moving the movable diaphragm, and is particularly suitable for use as a tank for transportation.

In the present invention, the term "tank" broadly refers to various types of containers that can contain powder, granules, and fluids, and includes, for example, hoppers.

Conventional tanks and hoppers for transportation have been designed and used as dedicated tanks or hoppers that can accommodate only one type of heavy oil, gasoline, cement, coal, etc., so to speak. Therefore, for example, when transporting heavy oil from an oil base to a cement factory, in the past, tanks were filled with heavy oil, but when the cargo was unloaded at the destination and returned, the tanks were transported empty. . For this reason, it was extremely uneconomical in terms of efficient operation of transportation facilities and labor saving.

Therefore, in order to solve this problem, the inside of the tank body is divided into a plurality of storage chambers by a movable diaphragm such as a rubber diaphragm, and these storage chambers are configured so that they can be used selectively. Various types of tanks for intermodal transportation have been proposed. In such a tank, when supplying a load to a predetermined storage chamber, a movable diaphragm between this predetermined storage chamber and an adjacent storage chamber is moved to the side of the adjacent storage chamber. We are trying to expand the capacity of the containment chamber.

As an example of such a tank, for example, the first
The configurations shown in FIG. 2 and FIG. 2 are conceivable.
1A and 1B, the width center of the tank body 1 is partitioned by a pair of left and right movable diaphragms 2, and these movable diaphragms 2, as shown in FIG.
As shown in FIG. A pair of rotating bodies 4 are pivotally supported on the front and rear walls 1a of the tank body 1, and the volumes of the storage chambers 5, 6, and 7 can be selectively changed by swinging the rotating bodies 4.

That is, as shown in FIG. 1A, when the rotating body 4 is swung in a direction in which its free ends approach each other, two left and right storage chambers 5 and 6 partitioned by a pair of movable diaphragms 2 are created.
are formed in the tank body 1, and the storage chambers 5 and 6 can store, for example, coal or the like.

Furthermore, if the pair of rotary bodies 4 are swung in a direction in which their free ends move away from each other, a storage chamber 7 is formed in the center of the tank body 1 as shown in FIG. 1B, and can accommodate cement, etc. I can do it.

By the way, the airtightness of each storage chamber 5, 6, 7 cannot be ensured unless the pair of movable diaphragms 2 are precisely and firmly attached to the tank body 1 and the distribution beam 3, respectively, as described above. is difficult.
However, this installation work is difficult due to the narrow tank body 1.
Since this is an internal and difficult task, it is time consuming and tends to significantly increase costs.

This idea replaces the conventional pair of movable diaphragms by
By using a bag-shaped movable diaphragm, the number of man-hours for installing the movable diaphragm is extremely reduced, and the durability of the movable diaphragm and the airtightness of the storage chamber are significantly improved.

Below is an example of applying the present invention to a railway hopper car for loading coal and cement.
The explanation will be given with reference to the drawings.

FIG. 3 is a longitudinal cross-sectional view of the railway hopper car. The tank body 10 is a rectangular container with an open top, and is supported by a pair of front and rear carriages 12. Further, the tank body 10 is provided with a funnel-shaped central hopper section 14 at the center of the bottom, as shown in the plan view of FIG.
There are opening/closing doors 16 on both the left and right sides (upper and lower sides in Figure 4) of the
A pair of hopper portions 18 having a V-shaped cross section are provided.

Reference numeral 22 in FIG. 3 is a support frame for a rotating body 24, which will be described later, and this support frame 22 also has the function of reinforcing the bottom of the above-mentioned tank body 10, which has a complicated structure. By the way, as shown in FIGS. 3 and 6, the support frame 22 has a plurality of pillar members 26 erected at equal intervals from the left and right wall surfaces 14c of the central hopper section 14, and these pillar members 26 are connected to a plurality of girders. It is rigidly connected by a member 27 and a longitudinal member 28.

The reason why the support frame 22 is not formed of a plate structure is to ensure that the support frame 22 does not obstruct the passage as much as possible when the cargo is discharged from the central hopper section 14.

Next, near the left and right ends of the central hopper part 14, a seventh
As shown in FIG. 8 and FIG. 8, a pair of rotating shafts 30 are provided, and these rotating shafts 30
It is supported by the front and rear walls of 0. Also, this rotating shaft 3
A rectangular rotating body 24 extending in the front-rear direction of the tank is fixed to the tank 0.

Next, cranks 38 as shown in FIG. 9 are provided at the ends of the pair of rotating shafts 30, respectively, and these cranks 38 are connected to rotating limbs 42 that project axially symmetrically from the deceleration shaft 40. They are connected via a rod 44.

Further, a pinion 50 and a gear 51 are respectively disposed between the shaft 48 of the crank handle 46 and the deceleration shaft 40 to decelerate the rotation of the rotary shaft 30.

Thus, in FIG. 9, for example, if the crank handle 46 is rotated clockwise, the deceleration shaft 40 will rotate counterclockwise in the figure, and as a result, the left and right rotation shafts 30
rotates, and the tips of the pair of rotating bodies 24 swing in a direction that moves away from each other. Also, the opposite of the above
When the crank handle 46 is rotated clockwise, this rotation rotates the rotating shaft 30 through the same path as described above, and the tips of the pair of rotating bodies 24 swing toward each other. move. In this case,
The width dimension of the rotating body 24 in the vertical direction is determined in advance so that the pair of tips do not compete with each other extremely.

By the way, inside the tank body 10, a bag-shaped movable diaphragm 20 having a loading port 54 at its upper part and an open bottom part is accommodated. This bag-like movable diaphragm 20 is made of a flexible sheet-like material, and when integrally molded, a distribution beam 66 is embedded in the vicinity of the loading port 54. Further, a plurality of tongue-like pieces 34 that form pairs with each other are provided protruding from the left and right outer surfaces of the movable diaphragm 20 at intervals approximately equal to the width of the rotating body 24 in the vertical direction.

In this way, both ends of the distribution beam 66 are attached to the tops of the front and rear walls of the tank body 10, respectively, and the open edges of the bottom are connected to the four circumferences 14a of the upper edge of the central hopper section 14, as shown in FIG. 4 or FIG. are fixed to each other by a plurality of rivets 14b, etc., and further, as shown in FIG. If the pair of tongue-shaped pieces 34 are fixed to both ends of the other surface of the rotating body 24 using a plurality of rivets 36, the attachment of the movable diaphragm 20 to the tank body 10 can be easily completed. .

Note that in order to fix the movable diaphragm 20 to the four circumferences 14a of the central hopper portion 14 as described above, coupling fittings such as bolts may be used, or adhesives, pressers, etc. may be used in combination. In addition, when storing fluid etc. in the tank body 10, the degree of this adhesion is
Particularly high airtightness is required.

By the way, the distribution beam 66 is a beam having a mountain-shaped cross section, and a fitting hole is provided at a position corresponding to the loading port 54 of the movable diaphragm 20. Then, as shown in FIGS. 3, 5, 7, or 8, a cylinder 55 with a circular cross-section and a lid that can be freely opened and closed is fitted into this fitting hole to form the loading port 54. For this fitting, a joining fitting such as a rivet may be used, or an adhesive, a presser foot, or the like may be used.
Note that the cylinder 55 is connected to the movable diaphragm 20 as described above.
It can also be attached in advance to the distribution beam 66 embedded in the.

Next, the operation of the tank constructed as described above will be described. When the pair of rotating bodies 24 are swung to the position shown in FIG. 7, the lower part of the movable diaphragm 20 is opened wide to the left and right. Therefore, when cement is injected from the loading port 54, the movable diaphragm 20 in the state shown by the dashed line in FIG. It will be fully loaded. This cement can be discharged downward from the discharge port 58 of the central hopper section 14 by opening it as necessary.

Next, when the pair of rotating bodies 24 are swung to the position shown in FIG. 8, the rotating bodies 24 are supported by the support frame 22, so coal can be loaded from the top of the open tank. As the cargo progresses, the movable diaphragm 20 deforms as shown by the solid line in FIG. 8, and the storage chambers 60, 661 of the tank are fully loaded with coal.

That is, the movable diaphragm 20 is doubled in the center of the tank as shown in FIG.
It becomes the bulkhead of 1. Further, the rotating body 24 is connected to the support frame 22.
Because it is supported by Note that the movable diaphragm 20 has sag due to a change in length in the vertical direction, but since the rotating body 24 forms a space 64 below the tank by approaching the tip, the movable diaphragm 20 The slack is accommodated in the space 64 by hanging down under its own weight. Therefore, the slack of the movable diaphragm 20 does not become a hindrance during loading. Further, the loaded coal can be easily discharged from the tank by opening the door 16 as shown by the dashed line in FIG.

Although the present invention has been described above with reference to one embodiment, the above-mentioned embodiment does not limit the present invention in any way, and various modifications can be made based on the technical idea of the present invention. For example, the present invention can be applied to railway tank cars for storing liquids and gases. Furthermore, it can be applied not only to railways, but also to tanks mounted on transportation vehicles in a broader sense, or to stationary tanks.

The present invention consists of a tank body, a distribution beam extending over the upper center of the front and rear walls of the tank body, and left and right beams installed approximately parallel to the distribution beam and supported at the bottom of the front and rear walls. A pair of rotating shafts, a pair of left and right plate-shaped rotating bodies each extending upward from these rotating shafts by a predetermined width, and a tank main body for dividing the tank main body into a plurality of storage chambers. a bag-shaped movable diaphragm installed inside the chamber and having an opening at the bottom thereof, and by swinging the rotating body to move the movable diaphragm, thereby changing the volume of the storage chamber. In the tank, the distribution beam and the movable diaphragm are integrally molded, and a pair of tongue-like pieces protruding at intervals approximately equal to the predetermined width of the rotating body are provided on the left and right outer surfaces of the movable diaphragm, respectively. and attaching both ends of the distribution beam and the periphery of the opening of the movable diaphragm to the tank body, respectively, and extending the portion of the movable diaphragm between the pair of tongue-shaped pieces onto one surface of the rotating body. The tank was constructed by fixing the pair of tongue-shaped pieces to both ends of the other surface of the rotating body.

Therefore, compared to the conventional case where a plurality of movable diaphragms are used to divide the tank body, as shown in FIGS. 1 and 2, the number of locations where movable diaphragms are attached to the tank body can be far reduced.

In addition, this movable diaphragm can be made by simply attaching the distribution beam integrally formed with the movable diaphragm and the periphery of the opening provided at the bottom of the movable diaphragm to the tank body, and attaching the tongue-shaped piece to the rotating body. Since the attachment to the container body is completed, the narrow and difficult work inside the container body is significantly reduced, and therefore the assembly of the container becomes dramatically easier.

Furthermore, the movable diaphragm has improved airtightness as the number of bonded parts is reduced, so troublesome leakage problems hardly occur, especially in the case of fluid transport. Moreover, the shortening of the length of the connecting portion also reduces the strength weak points of the movable diaphragm against repeated deformation, and has the effect of improving the durability of the movable diaphragm.
