Description

Container, especially container for transporting goods

Technical Field

The present invention relates generally to the field of shipping containers and, more particularly, to a shipping container.

Background

A container is a common transport vehicle used in the modern logistics industry. With the increasing transportation costs, the return utilization of containers has been a major concern. Conventional coil type containers for transporting coils (e.g., coil goods) also face return utilization issues. V-shaped stops are now commonly provided in coil type containers to prevent rolling of the coil during transport.

The bottom frame of the existing coil type container (as shown in figure 1) is provided with a V-shaped stop device. The stopping means comprises a V-groove 20 and a flip-open cover 30. A V-shaped channel 20 is provided in the middle of the chassis 10, and a flip cover 30 is pivotably coupled to both sides of the V-shaped channel 20 between a folded position and an unfolded position. When transporting rolled goods, the flip cover 30 is in the extended position and the V-shaped channel 20 on the chassis 10 is used to support the rolled goods. When transporting ordinary goods, the flip cover 30 is in the folded position, and the upper surface of the flip cover does not exceed the upper plane of the chassis 10, so that the goods can be loaded and unloaded. However, in order to load rolled goods with a large diameter, the size of the V-groove 20 (especially, the depth of the V-groove 20) on the chassis 10 needs to be increased, which inevitably increases the height of the chassis 10. The increased height dimension of the base frame 10, in turn, takes up more space within the container, increasing manufacturing and shipping costs.

There is therefore a need to provide a container that at least partially solves the above mentioned problems.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in detail so as not to obscure the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

First embodiment

A preferred embodiment of the present invention provides a shipping container. The container may be used to transport cylindrical cargo (e.g., rolled steel strip).

As shown in fig. 2 to 9, the container includes a bottom frame 110, a top plate, end walls, and side walls. The bottom frame 110, the roof, the end walls and the side walls enclose an interior space of the container for accommodating goods to be transported. The bottom frame 110 is laid with a floor 120. The base frame 110 includes a bottom beam. The bottom beam may be a bottom cross beam 111.

The container also includes a plurality (e.g., 3) of cargo support assemblies spaced along the length of the container. The cargo support assembly is disposed at a substantially middle position of the bottom chassis 110 in a width direction of the container. The goods supporting component is used for supporting the cylindrical goods. Each cargo support assembly may include two oppositely disposed support members 130.

Each support member 130 may include a cargo support plate 131. The cargo support plate 131 may be a rectangular structure. The longitudinal direction of the cargo support plate 131 is substantially parallel to the longitudinal direction of the container. The cargo support plates 131 of the two support members 130 of each cargo support assembly are oppositely disposed. The opposite ends of the two cargo support plates 131 of each cargo support assembly are pivotally connected to the bottom frame 110 of the container. Thus, the pivot axis of the cargo support plate 131 and the longitudinal direction of the container are substantially parallel.

The two cargo support plates 131 of each cargo support assembly have a stowed position and a raised position. When the cargo support plate 131 is in the storage position, the upper surface of the cargo support plate 131 is substantially flush with the upper surface of the floor 120 in the height direction of the container. In this case, the supporting member 130 does not occupy the inner space of the container and does not affect the loading and unloading of the general cargo, and thus, when the cargo supporting plate 131 is located at the storage position, the cargo can be transported. In an embodiment not shown, when the cargo support plate 131 is located at the storage position, the upper surface of the cargo support plate 131 may be lower than the upper surface of the floor 120 in the height direction of the container.

When the cargo supporting plate 131 is located at the lifting position, the plane where the cargo supporting plate 131 is located and the plane where the bottom plate is located form an included angle. Thus, the two cargo support plates 131 of each cargo support assembly form a V-shaped configuration. The V-shaped structure now extends in the length direction of the container. The cylindrical cargo described above can be transported through the V-shaped structure.

In this embodiment, the cargo support plate 131 is in the lifting position, that is, the cargo support plate 131 can transport cylindrical cargo, and the cargo support plate 131 is in the storage position, so that the upper surface of the cargo support plate 131 is flush with the upper surface of the floor 120, and further, a V-shaped groove is not required to be formed, the height of the chassis 110 is small, and the manufacturing and transportation costs are low.

Each support member 130 further includes a plurality of legs 132, a support beam 133, and a retaining member 134. The support beams 133 extend in the length direction of the container. The bottom cross member 111 of the underframe 110 is made of channel steel. The support beam 133 is disposed at the upper end of the bottom cross member 111 of the base frame 110. In other words, the lower surface of the support beam 133 is disposed on the bottom cross member 111. The limiting member 134 is a Z-shaped structure. The Z-shaped structure includes an upper cross arm, a lower cross arm substantially parallel to the upper cross arm, and an intermediate wall connecting the upper cross arm and the lower composite wall. The upper cross arm of the limiting member 134 is fixedly connected to the lower surface of the supporting beam 133 by bolts and nuts. The free end of the lower cross arm of the stop 134 extends into the opening of the bottom cross member 111. In this way, the stopper 134 can restrict the movement of the support beam 133 in the height direction of the container, and prevent the support beam 133 from falling out of the base frame 110. The support beam 133 can move in the length direction of the container. Thereby, the cargo support plate 131 is rotated to the lifted position, and then the support beam 133 is positioned at the later-described mounting step 135, at which time the upper surface of the support beam 133 abuts against the mounting step 135, and the support beam 133 supports the cargo support plate 131, so that the cargo support plate 131 is positioned at the lifted position. It is understood that in other embodiments, as shown in fig. 10, the support beam 133 of each support includes at least two sub-support beams (e.g., two). At least two of the sub-support beams are used to support different legs 132, respectively, to support the cargo support plate 131. Each sub-support beam is arranged on at least two bottom beams 111.

Each support member 130 includes a plurality (e.g., 4) of legs 132. A plurality of legs 132 are spaced apart along the length of the cargo support plate 131. The upper ends of the legs 132 are attached to the lower surface of the cargo support plate 131. The lower surface of each leg 132 is provided with a mounting step 135. The size of the mounting step 135 and the size of the support beam 133 are set correspondingly. In this way, the cargo supporting plate 131 is rotated to make the cargo supporting plate 131 in the lifted position, and at this time, the supporting beam 133 is moved to the mounting step 135 of the supporting leg 132 along the length direction of the container, so that the supporting leg 132 can be supported by the supporting beam 133, and the cargo supporting plate 131 is located in the lifted position, thereby bearing the weight of the cargo supporting plate 131 and the weight of the cylindrical cargo placed on the cargo supporting plate 131. The legs 132 are provided with mounting steps 135 to facilitate positioning of the support beams 133.

Preferably, the legs 132 and the cargo support plate 131 are rigidly connected. Such as legs 132 welded to cargo support plate 131. Or the legs 132 are secured to the cargo support plate 131 by bolts and nuts. This simplifies the structure of the support member 130.

Preferably, a plurality of (e.g., two) mounting steps 135 are provided at different locations on the leg 132. The plurality of installation steps 135 correspond to a plurality of support angles (an angle between a plane on which the cargo support plate 131 is located and a plane on which the bottom plate is located, an angle of the V-shaped structure) of the cargo support plate 131 in the lifted position one by one. Thus, when the support beam 133 is positioned in one of the plurality of installation steps 135, an angle between a plane in which the cargo support plate 131 is positioned and a plane in which the floor is positioned is a support angle corresponding to the installation step 135. Therefore, the angle between the plane where the cargo supporting plate 131 is located and the plane where the floor 120 is located can be adjusted by adjusting the mounting step 135 where the supporting beam 133 is located, and the angle of the V-shaped structure can be adjusted, so that the V-shaped structure can be used for transporting cylindrical cargos with different diameters.

The leg 132 is provided with a stopper protrusion 136 at a side of the mounting step 135 away from the pivotal position of the cargo support plate 131. Thus, when the support beam 133 is seated on the mounting step 135, the stopper protrusion 136 may restrict the support beam 133 from coming off the mounting step 135.

The legs 132 are provided with ribs 137. The reinforcing rib 137 is provided at the mounting step 135. The upper ends of the reinforcing ribs 137 are connected to the cargo support plate 131. The lower end of the reinforcing rib 137 is connected to the mounting step 135. Thus, the reinforcing rib 137 may reinforce the strength of the leg 132 at the mounting step 135.

In the present embodiment, when the cargo support plate 131 is rotated to the storage position, the support legs 132 are moved to the space between the bottom beams 111 of the bottom chassis 110 along with the cargo support plate 131, and the cargo support plate 131 is horizontally disposed on the bottom beams 111 of the bottom chassis 110, and at this time, the upper surface of the cargo support plate 131 does not protrude from the floor 120 of the container.

There is a space between the side of the cargo support plate 131 remote from its pivotal connection and the floor 120 of the container in the width direction of the container. The size of the gap corresponds to the size of the support beam 133. In this way, the spacing may be used to accommodate the support beam 133. When the cargo support plate 131 is located at the lifted position, the cargo support plate 131 is rotated upward (the cargo support frame is rotated in a direction away from the receiving position) to separate the support beam 133 from the mounting step 135, and the support beam 133 is moved in the length direction of the container to the interval, at which time the cargo support plate 131 is rotated to the receiving position. Thereby, the width of the cargo support plate 131 can be reduced. Preferably, the support beams 133 do not protrude from the floor 120 of the container when the cargo support panel 131 is in the stowed position.

Generally, when the cargo support plate 131 is located at the storage position, the lower surface of the cargo support plate 131 directly abuts against the upper surface of the bottom beam. The bottom beam supports the goods supporting plate 131, so that the goods supporting plate 131 has better strength when being located at a storage position to be used as an ordinary dry goods box.

Preferably, as shown in fig. 5, a bottom sealing plate 140 is further provided at the lower end of the container bottom frame 110. Bottom closure plate 140 covers the gap between bottom beams 111. When the goods backup pad is in the position of accomodating, the bottom butt bottom seal board of landing leg. In other words, the bottom closure plate supports the legs when the cargo support plate is in the stowed position. Thereby, the sealability and strength of the bottom chassis 110 may be increased. When the goods backup pad is in the position of accomodating, the bottom sealing board supports effort and the gravity of goods backup pad self of effect in the goods backup pad.

Second embodiment

The floor 220 and the support member 230 of this embodiment are substantially the same as those of the first embodiment. As shown in fig. 11, a plurality of cargo support assemblies are spaced along the length of the container. The length direction of the cargo support plate extends along the width direction of the container. One side of the cargo support plate in the width direction is pivotally connected to the base frame 210 with the pivot axis of the cargo support plate and the width direction of the container being substantially parallel. At this time, the bottom frame 210 is provided with a support longitudinal beam connected with the bottom cross beam. The bottom beam is a supporting longitudinal beam. The support stringers extend along the length of the container. The support longitudinal beam is made of channel steel. The support beam is arranged at the upper end of the support longitudinal beam. The free end of the lower cross arm of the limiting piece extends into the opening of the bottom cross beam. The other parts of the second embodiment are substantially the same as those of the first embodiment and will not be described again.

Third embodiment

In a third embodiment, as shown in fig. 12 and 13, each support member includes two bottom beam assemblies. Each bottom beam assembly includes two bottom beams and one support beam 333. The bottom beam may be the bottom cross beam 311. The bottom beam 311 is a channel steel. In each bottom beam assembly, the opening of one bottom beam 311 faces the opening of the other bottom beam 311, such that the openings of the two bottom beams 311 are opposite. The upper surfaces of both bottom beams 311 (the upper surfaces of bottom beams 311 in fig. 12) are substantially flush. Thus, in each bottom rail assembly, the two bottom rails 311 limit the installation space. The support beam 333 is disposed in the installation space. Both ends of the support beam 333 in the left-right direction of fig. 12 are located within the opening of the bottom cross member 311. The lower wing plate of the bottom cross member 311 supports the support beam 333. Such that the support beams 333 in each bottom beam assembly can move in the direction of extension of the bottom beam 311. The upper wing plate of the bottom cross member 311 may limit the movement of the support beam 333 in the height direction of the container to limit the support beam 333 within the installation space. In the left-right direction of fig. 12, there is a space between the two bottom cross members 311 of each bottom beam assembly. The space constitutes a support opening. In the left-right direction of fig. 12, a part of the legs 332 of each support member is located at the support port. Thus, the support beam 333 positioned in the installation space may support the leg 332 through the support opening. The bottom cross member 311 in the third embodiment may be substantially the same as the bottom cross member of the underframe in the first embodiment. In other embodiments, the bottom beams may also be the support stringers of the undercarriage of the second embodiment. The bottom closure plate 340 and the cargo support plate 331 of the third embodiment are substantially identical to the bottom closure plate and the cargo support plate of the first embodiment. The other parts of the third embodiment are substantially the same as those of the first embodiment and will not be described again.
