Description

  The present invention relates to a container for a box-type cargo used for maritime transportation, land transportation, and further air transportation, and in particular, allows a luggage compartment ceiling portion to be sufficiently opened and at the same time a peripheral wall panel portion. This also relates to a freight container with a new structure that can be opened.

Cargo containers are required to be robust in order to withstand the international logistics environment, and in addition, internationally standardized so that various cargo handling facilities such as cranes can be used for general purposes.
For this reason, conventional cargo containers are given priority to relatively high load resistance and advanced sealing functions, and when it comes to the opening of cargo handling work, a combination of a double door with a double door and a side sliding door is often used. ing.
However, depending on the cargo to be transported, it may be difficult or impossible to carry out the loading operation only with such an opening, and the operation itself may be dangerous.
As a specific example, for example, in the case of moving work of a general household, the piano and the like are relatively heavy in both weight and shape, so it is difficult to handle, and even if trying to use a container for general cargo, it is difficult to handle, many Requires the arrangement of a special vehicle with a separate crane. In addition, when attempting to store heavy machine tools etc. in a container with a crane suspended, if the cargo handling from the rear or side is impossible, only the ceiling part can be removed only during work. , The bolts fixing the ceiling panel were removed, the ceiling panel was removed, and the cargo was carried into the cargo compartment from above. Although it is possible to store special cargo in a container by such an aspect, naturally, the number of processes is large including incidental work, and efficient cargo handling work cannot be performed.
Moreover, in order to prevent the stability and damage of cargo during transportation, it is necessary to ensure that the cargo is accurately installed and secured, but observe the loading situation from the entire circumference during cargo handling operations. For this reason, if a worker who confirms and guides in the container waits for cargo handling, a very dangerous situation will occur as heavy objects are suspended at a close distance. In any case, there is no container in which the ceiling part is fully opened like a door, and there is nothing that satisfies the handling work of suspended loads from above.

  The present invention has been made in consideration of these various backgrounds, and can cope with loading and unloading of cargo suitable for cargo handling from above, such as hanging cargo handling work that has been relatively difficult to perform conventionally. This is an attempt to develop a new freight container that has a structure that allows visual confirmation of the above to be performed safely and easily.

The freight container according to claim 1 is a cargo container that constitutes a cargo room that can be appropriately sealed by a floor surface of the cargo room, a peripheral wall panel that rises from the floor surface, and a ceiling panel that faces the floor surface. In an apparatus for
The ceiling panel and the peripheral wall panel are supported by a frame disposed on each outer edge portion and configured to be openable respectively, and the ceiling panel extends in the longitudinal direction of the cargo compartment with respect to the support member of the ceiling panel. The center height of the ceiling panel when the ceiling surface is fully released is used as the pivot axis, and the center- folded ceiling panel that allows the entire folding surface to be opened by moving the center folding part upward. Is limited to approximately 1/2 of the width dimension of the container, and the lock of the free end of the ceiling panel is constituted by a tip lowering portion of a hatch guide rail that guides the tip roller, and an upper pressing piece provided thereabove. The holding pocket is provided with a structure performed by storing the tip roller,
The frame is provided with a movable beam that supports the ceiling panel in a closed state, and can move to a retracted position when the ceiling panel is opened .

Cargo Container according to claim 2, wherein, in addition to the requirements of claim 1, wherein for the center-folding shield structure in center-folding type ceiling panel, base panel or free end to be over the center of the center-folding unit Comprising a folded part cover plate provided on one of the panels and a folded part weather seal provided inside the folded part cover plate, and when the ceiling panel is closed, the folded part cover plate is It is characterized by being configured to cause a sealed state to appear by pressing the weather seal of the folded portion from above.

In addition to the requirements of claim 1 or 2 , the cargo container according to claim 3 has a tip cover plate, a tip weather seal provided on the inner lower surface, and a peripheral wall for the tip shield structure in the ceiling panel. It is characterized by comprising a tip falling portion in the tip cover plate that is externally fitted so as to surround the upper end of the panel.

According to the first aspect of the present invention, since the work can be performed with both the ceiling panel and the peripheral wall panel of the cargo container open, for example, when a heavy object from above is stored, If the device exists, a very efficient cargo handling operation is possible.
At that time, when the worker performs guidance or the like, the worker can be guided outside without entering the container and the side surface is opened, so the reliability and safety of the work are improved.
And since such heavy objects are also sufficiently fixed in the container, so-called lashing work is also required, but since such work can also be done with the worker in the closest position with the peripheral wall panel open. More efficient work can be done.
In addition, it is configured so that the ceiling surface and the peripheral wall panel in the cargo container can be opened. Therefore, it is difficult to use this part as an overall strength member. A freight container having sufficient strength can be obtained.
Furthermore, when the ceiling surface is opened, the height of the rising of the ceiling panel can be kept low, so that there is no need for an extra upper height margin in a place where cargo handling work is performed, such as a warehouse. In addition, in the case of operation with a crane or the like, when the operator hangs the load, it is possible to minimize the hindrance to the visual state and to perform accurate loading.
Furthermore, when the ceiling panel is in the closed state, the free end lock is automatically performed, and the situation where the free end side opens upward due to an impact or the like can be completely avoided.
Furthermore, the ceiling panel is securely supported by the movable beam when the ceiling panel is closed.

Further, according to the invention described in claim 2 , in the middle-folded type ceiling panel, the sealing of the middle-folded portion is ensured, and the penetration of rainwater or the like which is a concern in the case of a structure in which the ceiling portion can be opened. Can be completely prevented.

Further, according to the invention described in claim 3 , rainwater or the like can be reliably sealed even on the free end side of the ceiling panel.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention includes an embodiment described below, and also includes embodiments with various improvements based on this technical idea.

Hereinafter, the present invention will be specifically described based on illustrated embodiments.
The cargo container 1 of the present invention is loaded on a cargo vehicle T such as the trailer / tractor type shown in the figure, and is loaded on a rail freight vehicle for ground transportation, as well as marine transportation and air transportation by ship and aircraft. It is used for
The cargo container 1 has an upper surface constituted by a ceiling panel 2, and a floor 3 provided opposite to the cargo container 1 and a peripheral wall panel 4 rising from the floor 3 constitutes a sealed cargo room S inside. Is. Of these, the peripheral wall panel 4 is substantially constituted by a rear door 5, a front fixing panel 6, and a side panel 7.

  More specifically, these members are configured with the frame 10 as a skeleton member, and the floor surface 3 includes a floor frame frame 11 having a rectangular shape in plan view at an outer peripheral position thereof. The floor frame 11 further includes a frame member such as a cross-shaped structure having a necessary strength, although illustration is omitted. A fork slot 110 for receiving an operation such as a forklift is provided on the side surface. The four pillar frames 12 are provided so as to rise from the four corners of the floor frame 11, and the rear beam 13 is provided at the upper end of the floor frame 11 and the front beam 14 is provided at the front of the floor frame 11 so as to connect them. Side beams 15 and 16 are provided on both side surfaces. The side beam 15 serves as an open base when the ceiling panel 2 described later is composed of a half-fold type ceiling panel 20, and the other side beam 16 serves as an open side. Further, hatch guide rails 17 that contribute to the opening and closing of the folding center type ceiling panel 20 are provided inside the rear beam 13 and the front beam 14, respectively, and the hatch guide rails 17 have their tips on the open side, that is, on the side beam 16 side. It includes a tip descending portion 171 that is slightly inclined downward, and a base raising portion 172 that raises the guide position on the side beam 15 on the opposite side.

Next, the ceiling panel 2 will be described.
In the embodiment shown in FIG. 1 to FIG. 5, the ceiling portion is constituted by the middle-fold type ceiling panel 20. First, the half-fold type ceiling panel 20 will be described. In this, the ceiling panel unit 21 in which the base panel 21A and the free end panel 21B are combined is opened in a half-fold shape, and when closed, the upper edge of the rear beam 13, the front beam 14, and the side beams 15, 16 is used. It becomes a flat state so as to cover. First, the base panel 21A is pivotally attached to the side beam 15 in the frame 10 by a base panel hinge 22a serving as a pivot base. In addition, the base panel 21A and the free end panel 21B are configured to be bent in a mountain-like manner by the middle folding hinge 22b. The free end panel 21B has a front end roller 23 attached to the front end side via a roller stay 23a.

  The ceiling panel cylinder 24 is used for opening and closing the center-folded ceiling panel unit 21 as described above. This ceiling panel cylinder 24 connects the panel cylinder body 24a to the rear beam 13 and the front beam 14 so as to be rotatable at a panel cylinder base pivot 25a, and the panel cylinder rod 24b at the other end is a panel in the base panel 21A. It is rotatably connected to the cylinder movable pivot 25b side.

Such a middle-folded ceiling panel unit 21 is further provided with a front end lock structure 26, a base shield structure 27, a middle-fold shield structure 28, and a front-end shield structure in order to maintain a completely sealed state of the cargo compartment S. 29.
First, the tip lock structure 26 will be described.
As shown in FIGS. 5, 6, and 7, an example of the tip lock structure 26 is a tip side (side beam) of a hatch guide rail 17 provided by using the rear beam 13 and the inner side surface of the front beam 14 in the frame 10. 16 side). That is, the hatch guide rail 17 has a configuration along the entire width of the rear beam 13 and the front beam 14, but is lowered downward near the front end of the hatch guide rail 17 and close to the side beam 16 to form a front end lowering portion 171. To do. On the other hand, an upper pressing piece 251 is provided on the frame 10 at this portion, and a space between the tip lowering portion 171 and the upper pressing piece 251 is used as a holding pocket 252.

As a result, when the half-folded ceiling panel unit 21 is closed, the tip roller 23 is stored in the holding pocket 252, and the base panel 21A and the free end panel 21B are both connected in a flat plate state. In this case, a state where the free end is lifted upward around the base panel hinge 22a is completely avoided. Of course, the position of the tip roller 23 is important for fitting the tip roller 23 into the holding pocket 252, and the tip roller 23 is almost near the tip of the free end panel 21B, and in the vertical direction. The free end panel 21 </ b> B is provided with a height corresponding to the depth of the tip lowering portion 171.
Further, the hatch guide rail 17 raises the range on the base side, that is, the side beam 15 side to form a base raising portion 172. As a result, as shown in FIG. 4, when the ceiling panel unit 21 is opened, the tip of the free end panel 21 </ b> B is sufficiently raised so that the tip of the ceiling panel unit 21 does not interfere with the upper end of the frame 10.

Next, the base shield structure 27 will be described.
The base shield structure 27 is a shield structure between the side beam 15 and the base panel 21 </ b> A of the half-fold type ceiling panel 20. Specifically, as shown in FIG. 5, a flexible seal sheet 227A is stretched so as to cover the upper surface of the rotation center.

Next, the half-fold shield structure 28 will be described.
As shown in FIG. 8 (a), this includes, as an example, a reverse channel-shaped folded portion covering plate 281 that is provided in the vicinity of the folded portion of the base panel 21A. In addition, a rising portion 281a is provided on the base end side, a top portion 281b is continuously provided on the upper surface thereof, and a distal end pressing portion 281c is provided on the other end of the top portion 281b. A folded portion weather seal 282 is provided so as to be held by such a folded portion cover plate 281. This is, for example, a hollow rubber-like member, and when the ceiling panel 2 is closed, as shown in the lower part of FIG. 8A, the folded portion weather seal 282 contacts the free end panel 21B on the lower surface. However, the upper part is pressed by the tip pressing part 281c in the center folding part cover plate 281 and, as a result, is pressed to the free end panel 21B with a certain elasticity, so that a sealed state appears. .

Next, the tip shield structure 29 will be described.
As shown in FIG. 7, as an example, a tip end cover plate 291 that is an angle-shaped member, a tip weather seal 292 provided on the inner side (lower surface), a frame, and a frame are provided. 10 and a seal receiving rib 293 provided on the side beam (open side) 16. That is, the front end cover plate 291 is a member having an angled cross section including a front overhang portion 291a and a front end lowering portion 291b, and a front end weather seal 292 is provided on the lower surface of the front overhang portion 291a. . In the closed state, the front end weather seal 292 is sandwiched between the seal receiving ribs 293, and the front end lowering portion 291 b of the front end cover plate 291 is covered outside the upper end of the side beam 16. It has a sealing effect.

Next, the rear door 5, the front fixing panel 6, and the side panel 7 constituting the peripheral wall panel 4 will be described. First, the rear door 5 is a door of a kannon door as an example, and is opened and closed by a hinge 51 provided on the rear beam 13 on the rear side 2 as shown in FIGS. In addition, a latch device 52 according to a conventional method is provided. On the other hand, the front fixing panel 6 is normally provided in a fixed state, but of course, it may be provided with a door that opens this part.
Further, the side panel 7 has a structure in which the side beam 15 and the side beam 16 are used as supporting members and are opened in a hatch shape by hinges 71, respectively. In the illustrated embodiment, the side panel 7 is opened in a single-piece configuration, which also includes a latch structure 72 according to a conventional method and an assist cylinder 73 that opens the latch structure 72. The assist cylinder 73 can be configured so that the side panel 7 can be opened and closed by its own shift drive. However, the assist cylinder 73 is configured to assist manual opening by the function of an appropriate counter balancer such as a gas damper. But it does n’t matter. Also, the side panel 7 can take various forms as will be described later. However, any of the side panels 7 can be opened even when the ceiling panel 2 is opened.

The cargo container 1 of the present invention has the above-described configuration as a basic configuration and operates as follows. First, the operating state in this basic configuration will be described.
≪Initial condition≫
First, the state where all the cargo compartments S in the cargo container 1 of the present invention are closed will be described as the initial state. In this initial state, the rear door 5 and the side panel 7 constituting the peripheral wall panel 4 are closed, and the ceiling panel 2 is also closed.
In the ceiling panel 2, the ceiling panel unit 21 is in a state where the base panel 21 </ b> A and the free end panel 21 </ b> B are flat and continuous, and covers the ceiling surface of the luggage compartment S. In this state, the ceiling panel cylinder 24 is in a contracted state.
Further, the front end roller 23 on the free end panel 21 </ b> B side is in a state of being accommodated in the holding pocket 252.

≪Main cargo handling status≫
The cargo handling work from the ceiling surface, which is the main aim of the present invention, is performed as follows.
First, when it is sufficient that only the ceiling panel 2 is opened, for example, when storing bulk-shaped luggage or the like, only the upper part is opened, but the cargo container 1 of the present invention is most effective. When loading and unloading heavy objects to be carried from above, it is preferable to work as follows.
First, when opening the ceiling panel 2, the ceiling panel cylinder 24 is extended to cause the ceiling panel unit 21 including the base panel 21 </ b> A and the free end panel 21 </ b> B to be raised upward in a folded state. The ceiling panel unit 21 is lifted around the center folding hinge 22b, and the distal end roller 23 on the distal end side rolls on the hatch guide rail 17, and first comes out from the distal end descending portion 171 toward the proximal end side. The free end panel 21 </ b> B rises at a stroke as it rises, and the base end portion 291 in the front end shield structure 29 moves so as not to interfere with the side beam (rotation side) 16. It is drawn toward the panel 21A side to obtain an open state. At this time, the free end panel 21 </ b> B is further raised by the base rising portion 172 in the hatch guide rail 17 and moves so as not to interfere with the upper end of the frame 10. In this state, a form is adopted in which the ceiling panel unit 21 rises toward the side beam 15 in a state where the ceiling panel unit 21 is folded in a folded shape.
Even in the side panel 7 in the peripheral wall panel 4, in the case of the hatch type, the hinge 71 is opened upward. Of course, the side panel 7 is operated by opening both of them or by opening only one side. The rear door 5 is also opened as necessary.

In such a state, for example, the heavy object is lifted by a crane or the like, and the operator aims at the floor surface 3 of the luggage compartment S and lowers it to install it at a predetermined position. At this time, since the side panel 7 is released, the worker who guides the cargo handling work can enter the work from a short distance although it does not enter the floor surface 3. When the load B is installed on the floor 3, the worker can access the load B from the side, and the lashing operation for fixing the load can be performed reliably.
After the completion of such work, the side panel 7 and the rear door 5 which have been appropriately opened are closed. Further, the ceiling panel 2 is closed, but its operation causes the ceiling panel cylinder 24 to contract and causes the base panel 21A to fall down. Along with this, the free end panel 21B also falls down while maintaining a half-fold shape, and finally, a state in which the base panel 21A and the free end panel 21B are formed into a single flat plate shape is obtained.

As can be understood from such an operation mode, various opening / closing drive structures for the ceiling panel 2 using the ceiling panel cylinder 24 as an example can be applied.
For example, hydraulic cylinders, hydraulic actuators, electric cylinders, electric actuators, gas dampers, screw jacks, pneumatic cylinders, pneumatic actuators, rod actuators, linear actuators, racks, pinion mechanisms, push-up devices using winding springs, etc. are applied However, it is also possible to drive directly by these, or to open and close the ceiling panel 2 by combining these devices with links, wires, pulleys and the like.

≪Maintenance of closed state: Maintenance of sealed state≫
At this time, the front end roller 23 in the free end panel 21B is in a state of being fitted into the holding pocket 252 and is maintained in a state in which the ceiling panel unit 21 is not opened even when subjected to an impact or the like.
Further, by the middle folded shield structure 28, the middle folded weather seal 282 obtains a sealed state of the upper surface of the base panel 21A and the free end panel 21B at the middle folded section. Of course, the middle-folded part shield structure 28 is not limited to the form shown in FIG. 8A, but a simple form in which a so-called mountain rubber or the like is arranged at the center as shown in FIG. 8B. But it doesn't matter.

Also, at the distal end portion, a sealing state on the distal end portion side is obtained by the action of the distal end weather seal 292, and further the distal end lowered portion 291b and the seal receiving rib 293 on the distal end portion cover plate 291.
Of course, the tip shield structure 29 is not limited to the configuration shown in FIG. 6 and can be a structure shown in FIG. That is, this form is a combination of a pair of tip weather seals 292a and a tip weather seal 292b. First, the tip weather seal 292a is provided at the upper edge of the side panel 13. On the other hand, the tip weather seal 292 b is provided inside the tip cover plate 291 of the ceiling panel unit 21. When the ceiling panel unit 21 is closed, the two end weather seals 292a and 292b come into contact with each other and are pressed against a part of the ceiling panel unit 21 of the end weather seal 292. It is done.
Each shield structure has been described only for basic members, but in order to ensure waterproofing, use a combination of waterproof rubber, waterproof rubber packing, resin packing, water-resistant sealer, waterproof cloth sheet, etc. in accordance with conventional methods. There is no problem as well.

When the cargo B stored in the cargo container 1 is unloaded, the procedure is the reverse of the above-described loading operation. Of course, when there is no lifting means such as a crane for unloading the load B, the side panel 7 can be opened to bring the forklift etc. close to the close distance of the load B and can be taken out by the forklift. is there.
In addition to such a basic configuration, the present invention is characterized by including a movable beam 18 that supports a ceiling panel.

That is, what is shown in FIG. 12 is a movable beam 18 for supporting the ceiling panel 2 provided on the ceiling surface. One feature of the present invention is that the ceiling surface is fully opened. In such a configuration, the ceiling panel 2 may be required to be supported, but the movable beam 18 is provided in order to meet the contradictory requirements of providing a member for supporting and fully opening. . That is, the movable beam 18 is, for example, two support members along the width direction of the cargo container 1, and both ends thereof are supported by the left and right side beams 15 and 16. The movable beam 18 is configured to be moved from the support operation position to the retreat position near the rear beam 13 or the front beam 14 by the driving means 182 such as a chain by the movement of the roller 181. Thereby, when the ceiling panel 2 is closed, the movable beam 18 is set at an intermediate position in the longitudinal direction of the cargo container 1 and acts to support the ceiling panel 2. On the other hand, when the ceiling panel 2 is opened and the ceiling surface is fully opened, the movable beam 18 is moved to the front and rear withdrawal positions.
