Description

[Detailed description of the invention] This invention consists of a container body, a distribution beam that spans approximately the upper center of the front and rear walls of the container body, and a distribution beam that is provided approximately parallel to the distribution beam and at the bottom of the front and rear walls. a pair of left and right rotating shafts supported by a pair of left and right rotating shafts, a pair of left and right plate-shaped rotating bodies each extending upward from these rotating shafts by a predetermined width, and dividing the container body into a plurality of storage chambers. A bag-shaped movable diaphragm is provided in the container body in order to move the movable diaphragm by swinging the rotating body, thereby changing the volume of the storage chamber. The present invention is particularly suitable for transportation containers.

That is, in conventional containers in which a movable diaphragm can be moved to change the volume of a desired storage chamber as needed, the movable diaphragm is assembled from a plurality of members in order to adapt the movable diaphragm to the container.

For example, configurations as shown in FIGS. 1 and 2 can be considered. That is, as shown in FIGS. 1A and 1B, the center of the width of the container body 1 is partitioned by a pair of left and right movable diaphragms 2, and these movable diaphragms 2 have front and rear ends facing toward the front and rear of the container body 1, as shown in FIG. wall 1a
In addition, the upper end is fixed to the distribution beam 3 bridged between the front and rear walls 1a, and the lower end is fixed to the bottom 1b of the container body 1, so that the pair of rotating bodies 4 are attached to the container body 1.
The rotating body 4 is pivoted on the front and rear walls 1a of the storage chamber 4, and the volumes of the storage chambers 5, 6, and 7 can be selectively changed by swinging the rotating body 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, the two left and right storage chambers 5 and 6 partitioned by a pair of movable diaphragms 2 are moved into the container body 1. The storage chambers 5 and 6 can store, for example, coal.

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

By the way, these pair of movable diaphragms 2 must be securely attached to the container body 1 and the distribution beam 3 around the periphery so as not to create any gaps as described above, otherwise the storage chambers 5, 6, and 7 will be damaged. It is difficult to ensure airtightness. However, such installation work is difficult and takes place within the narrow space of the container body 1, and therefore tends to take time and significantly increase costs.

This idea forms a movable diaphragm with a sealed bag-like body that is integrally formed from a flexible sheet-like material, and extremely reduces the number of man-hours required to install the movable diaphragm.
Furthermore, the durability of the movable diaphragm and the airtightness of the storage chamber have been significantly improved.

Hereinafter, an embodiment in which the present invention is applied to a transportation vehicle for loading coal and oil will be described with reference to the drawings.

FIG. 3 is a partial vertical sectional view of a transportation vehicle equipped with a container of this invention, and the container body 10 has a shape close to a rectangular parallelepiped with an open top. Further, inside the container body 10, a bag-like body integrally formed from a flexible sheet-like material and having a sealed shape is housed as a movable diaphragm 11. Further, in the upper part of this bag-like body, there is provided an inlet/outlet port 12 for contents to be supplied to or discharged from the container. As shown in FIGS. 4, 5A, or 5B, the inlet/outlet 12 is made of a metallic cylinder 17 having a circular cross section and provided with a lid 14 that can be opened and closed.

Next, on the left and right sides near the bottom 10b of the container body 10, there is a pair of rotation shafts 18 shown in FIGS. 5A and 5B.
are provided, and these rotating shafts 18 are connected to the container body 1.
It is pivotally supported by the front and rear walls 10a of 0. Further, a rectangular rotating body 19 that extends in the front-rear direction of the container body 10 is fixed to the rotating shaft 18 .

Furthermore, cranks 24 as shown in FIG. 6 are provided at the ends of the pair of rotating shafts 18, respectively.
These cranks 24 are connected via connecting rods 27 to rotating limbs 26 that project axially symmetrically from the deceleration shaft 25 .

Further, a pinion 32 and a gear 33 are respectively disposed between the shaft 31 of the crank handle 28 and the deceleration shaft 25 to decelerate the rotation of the rotary shaft 18.

Thus, in FIG. 6, for example, crank handle 2
8 rotates clockwise, the deceleration shaft 25 rotates counterclockwise in the figure, and as a result, the left and right rotating shafts 18 rotate, and the tips of the pair of rotating bodies 19 move away from each other. oscillate. The rotating body 19 is ultimately supported by the inclined portions 10c formed at the lower portions of the left and right walls of the container body 10, as shown in FIG. 5A.

Further, if the crank handle 28 is rotated counterclockwise, which is opposite to the above, this rotation rotates the rotating shaft 18 through the same path as described above, and the tips of the pair of rotating bodies 19 are rotated. swing in the direction of approaching each other.

In this case, the front and rear walls 10a of the container body 10 are provided with an eight-shaped support 35 protruding from the front and rear walls 10a to support the rotating body 19 as shown in FIG. 5A or 5B. As shown, both ends are supported by this support body 35 and rotation is stopped.
Note that the vertical width dimension of the rotating bodies 19 is determined in advance so that when the pair of left and right rotating bodies 19 are supported on the support body 35 in this manner, the tips do not compete with each other extremely.

By the way, when the movable diaphragm 11 is integrally molded as described above, the distribution beam 13 having a mountain-shaped cross section is embedded in the movable diaphragm 11 in the vicinity where the entrance/exit port 12 is provided. In addition, on the left and right outer surfaces of the movable diaphragm 11, a plurality of tongue-like pieces 20 are arranged in pairs.
They are provided protrudingly at intervals approximately equal to the width of the rotating body 19 in the vertical direction. Note that the cylindrical body 1 of the inlet/outlet 12
7 may be provided integrally with the distribution beam 13 in advance, or, as described above, after integrally molding the movable diaphragm 11 and the distribution beam 13, the hole 7 may be provided in advance in the distribution beam 13 and the movable diaphragm 11. This cylindrical body 17 may be fitted. For this fitting, coupling fittings such as rivets may be used, or adhesives, pressers, etc. may also be used.

Thus, both ends of the distribution beam 13 are attached to the front and rear walls 10a of the container body 10, respectively, as shown in FIG. If the pair of tongue-shaped pieces 20 are respectively fixed to both ends of the other surface of the rotating plate-shaped body 19 so that the portion of the plate-shaped rotating body 19 is extended, the container body 10 of the movable diaphragm 11 Extremely easy to install,
Finish easily.

That is, since the movable diaphragm 11 is fixed to the container body 10 by the pair of rotating shafts 18 and the distribution beam 13 fixed to the container body 10, the movable diaphragm 11 is attached to the bottom 10b of the container body 10. The movable diaphragm 11 can be attached to the container body 10 without fixing the bottom surface of the container 11.
It does not float within the container and maintains a substantially constant position relative to the container body 10. However, if necessary, the lower surface of the movable diaphragm 11 may be fixed to the bottom portion 10b, and part of the front and rear surfaces of the movable diaphragm 11 may be fixed to the central portion of the front and rear walls 10a.

Next, the operation of the container configured as described above will be described. When the pair of rotating bodies 19 are swung to the position shown in FIG. 5A, the lower part of the movable diaphragm 11 is opened wide to the left and right. Therefore, when petroleum is injected from the loading/unloading port 12, the movable diaphragm 11, shown by the dashed line in the same figure, deforms as shown by the solid line in the figure as loading progresses, and the container body 10 is filled with petroleum in the storage chamber 34. It will be fully loaded.

Next, when the pair of rotary bodies 19 are swung to the position shown in FIG. 5B, when coal is loaded into the container body 10 from above, the movable diaphragm 11 moves along the solid line in FIG. 5B as loading progresses. The container is deformed in such a manner that the storage chambers 38 and 39 are fully filled with coal.

That is, the movable diaphragm 11 is doubled at the center of the container body 10 as shown in FIG. 5B, and serves as a partition between the left and right storage chambers 38 and 39. Moreover, since the rotating body 19 is supported by the support body 35, it can sufficiently withstand the load of coal. Note that this movable diaphragm 11 has sag due to a change in length in the vertical direction, but since the rotating body 19 forms a space 40 below the container body 10 by the approach of the tip,
The slack of the movable diaphragm 11 is accommodated in the space 40 by hanging down under its own weight. Therefore, the movable diaphragm 11 does not become a hindrance during loading. Further, the loaded coal can be easily discharged from the container body 10 by opening the opening/closing door 41 as shown by the dashed line in FIG. 5B.

Although the present invention has been described above with reference to one embodiment, the above-mentioned embodiment is not intended to limit the present invention.
Various modifications are possible based on the technical idea of the present invention. For example, the present invention can be applied to transportation vehicles for storing powder or gas. It can also be used as a stationary container.

The present invention consists of a container main body, a distribution beam extending over approximately the upper center of the front and rear walls of the container main body, and left and right channels installed approximately parallel to the distribution beam and supported at the lower portions of the front and rear walls. A pair of rotating shafts, a pair of left and right plate-shaped rotating bodies each extending upwardly from these rotating shafts by a predetermined width, and a rotating body inside the container body for dividing the container body into a plurality of storage chambers. a bag-shaped movable diaphragm provided in the container, the container is configured to swing the rotating body to move the movable diaphragm, thereby changing the volume of the storage chamber; and the movable diaphragm are integrally molded, and a pair of tongue-shaped pieces protruding at intervals approximately equal to the predetermined width of the rotary body are provided on the left and right outer surfaces of the movable diaphragm, respectively, and both ends of the distribution beam are attached to the container body, and the pair of tongues are attached to the other surface of the rotating body in order to extend the portion of the movable diaphragm between the pair of tongues onto one surface of the rotating body. A container was constructed in such a way that it was fixed to both ends of the container.

Therefore, compared to the conventional case where a plurality of movable diaphragms are used to divide the inside of the container body as shown in FIG. 1A, 1B, or 2, the number of locations where movable diaphragms are attached to the container body is far reduced. be able to.

In addition, this movable diaphragm can be attached to the container body simply by attaching the distribution beam molded integrally with the movable diaphragm to the container body, and by attaching its tongue-like piece to the rotating body. Therefore, the assembly of the container becomes dramatically easier.

Furthermore, the movable diaphragm has improved airtightness due to the reduced number of bonding parts, so that troublesome leakage problems hardly occur, especially in the case of fluid transport.

Furthermore, the shortening of the length of the connecting portion has the effect of reducing the weak points of the movable diaphragm against repeated deformation, thereby improving the durability of the movable diaphragm.
