Description

Platform type container

Technical Field

The invention relates to the technical field of containers, in particular to a platform-based container.

Background

The existing transportation equipment for goods like rolls generally comprises a groove with an inclined plane. The inclined plane of the groove can limit goods such as rolled goods and columnar goods, so that the goods are prevented from moving due to impact force and swinging bias force in the transportation process, and can be in a stable state. The grooves are generally provided to be depressed downward from the top surface of the bottom chassis, or the grooves are formed by a load bearing member having a slope protruding from the top surface of the bottom chassis. Because the grooves are generally fixedly arranged on the chassis structure of the transportation equipment, the transportation equipment can only transport the rolled goods specially, and can not transport the goods different from the return journey, such as the rolled goods with different sizes or other types of goods. Therefore, the existing roll-shaped goods transportation equipment cannot provide a proper transportation platform for transportation in the processes of going and returning, and can only be transported back in an empty box, so that the transportation cost is undoubtedly increased.

Accordingly, there is a need for a rack-based shipping container that at least partially addresses the problems of the prior art.

First preferred embodiment

Fig. 1 and 2 show a rack type container 100 according to a first preferred embodiment of the present invention, for loading goods such as roll goods, column goods, etc., and flat goods such as plate goods, box goods, etc.

As shown in fig. 1 and 2, the rack container 100 includes a loading platform 110. The loading platform 110 is generally configured as a rectangular parallelepiped platform having a length, a width, and a height. The loading platform 110 comprises a chassis 120 and a first bearing structure 130 and a second bearing structure 140 arranged on the chassis 120. In a state where the loading platform 110 is horizontally placed, the bottom chassis 120 defines a first surface P1 extending in a horizontal direction and a second surface P2 opposite to the first surface P1. The first and second surfaces P1 and P2 are outer surfaces of the bottom chassis 120. The first bearing structure 130 is disposed on the first surface P1, and the second bearing structure 140 is disposed on the second surface P2. In other words, the first load bearing structure 130 and the second load bearing structure 140 are oppositely oriented.

In a state where the first surface P1 is located above the second surface P2, the first surface P1 is a use surface, the second surface P2 is a non-use surface, and the first carrying structure 130 is used for carrying the first cargo. In a state where the second surface P2 is located above the first surface P1, the first surface P1 is a non-use surface, the second surface P2 is a use surface, and the second carrying structure 140 is used for carrying the second cargo. In this embodiment, the second load bearing structure 140 is different from the first load bearing structure 130, such that the rack container 100 can transport different types and/or sizes of cargo by means of the two load bearing structures.

Since the first surface P1 is opposite surfaces of the bottom chassis 120 of the second surface P2, the position of the first bearing structure 130 and the position of the second bearing structure 140 may be exchanged by turning over the bottom chassis 120. The loading platform 110 may be vertically turned by means of a turning tool such as a forklift, a crane, or the like. The turned first and second surfaces P1 and P2 still extend in the horizontal direction, that is, the turning angle is substantially 180 °.

Further, as shown in fig. 1, the first load bearing structure 130 is configured as a rolled good recess having opposite load bearing surfaces. The rolled good recess opens outwardly and is recessed inwardly relative to the first surface P1, but does not project beyond the second surface P2. Optionally, the rolled good flutes taper from the outside inward along the depth of the trough to facilitate entry or exit of goods into or out of the rolled good flutes. The cross section of the rolled goods groove can be at least one of V-shaped, U-shaped with radian and inverted trapezoid. Preferably, the cross-sectional shape of the rolled goods recess is an inverted trapezoid. It should be noted that the "sectional shape" mentioned herein is a shape taken along a vertical plane in which the longitudinal direction of the chassis 120 is located. References herein to "length direction", "width direction" and "height direction" are with respect to the undercarriage or loading platform.

It should be noted that the "rolled goods groove" mentioned herein is only a name schematically showing the groove, and does not mean that the groove can only carry rolled goods. In contrast, the rolled goods groove can not only bear rolled goods, but also goods such as column goods. It is to be understood that references herein to "outer" and "inner" are with respect to a rack container, e.g., inward in a direction toward the rack container and outward in a direction away from the rack container.

As shown in fig. 2, the second load bearing structure 140 may be configured as a load bearing plane. The bearing plane is approximately flat so as to load flat goods. The illustrated embodiment shows that the bearing plane may be in the same plane as the second surface P2. In particular, the second load-bearing structure 140 may be made of a plate-shaped member.

Further, the chassis 120 is configured as a substantially rectangular parallelepiped. Eight corners of the rectangular parallelepiped are respectively provided with a coupling member 122 having a coupling hole 121 so as to satisfy operations such as general stacking, lifting, coupling, and the like. Alternatively, the hitch member 122 is preferably a corner fitting. The loading platform 110 may further include a corner post 123, and the corner post 123 is disposed between two corner pieces 122 correspondingly disposed in the height direction. Specifically, the undercarriage 120 includes a bottom side beam 124 extending along a length thereof, and a bottom end beam 125 extending along a width thereof. It is understood that the first surface P1 may be understood as a surface defined by the first horizontal surface of the bottom side beam 124. The second surface P2 may be understood as a surface defined by a second horizontal surface of the bottom side rail 124 opposite the first horizontal surface described above. Corner posts 123 are provided at adjacent bottom side beams 124 and bottom end beams 125 to strengthen the structure of the loading platform 110 at the corner ends. The bottom side beams 124 and the bottom end beams 125 each have substantially the same predetermined dimension in the height direction of the underframe 120 to meet the depth requirement of the rolled goods recess.

The loading platform 110 may also be provided with a first fork pocket 150 between the first surface P1 and the second surface P2. The first fork grooves 150 extend through the bottom side beams 124 at both sides in the width direction of the base frame 120 to enable the carrying operation of the rack container 100 by means of a forklift in an empty or loaded state. Optionally, as shown in fig. 1 and 3, the bottom of the first fork pocket 150 is further provided with a storage slot 160 for storing some items, such as a coupling rod 401 described below.

Alternatively, two or more rolled goods recesses may be provided along the length of the loading platform 110 to transport a plurality of rolled goods simultaneously. For example, the illustrated embodiment shows 3 rolled cargo recesses disposed along the length of the chassis 120. The rolled goods recess extends in the width direction of the chassis 120, and goods may be placed in the rolled goods recess in the width direction of the chassis 120. In such an embodiment, the end of the rolled good recess may protrude beyond the first surface P1. As shown in fig. 2, in a state where the second surface P2 is positioned above the first surface P1, the end of the adjacent rolled good groove and the first surface P1 of the chassis 120 may form a second fork groove 170. Specifically, the second fork groove 170 is opened outward and extends through in the width direction of the bottom chassis 120. In a state where the second surface P2 is located above the first surface P1, the rack container 100 in an empty box or a loaded state may be carried by means of the second fork groove 170.

In the rack container 100 of the present embodiment, for example, during the outward movement, the first surface P1 of the loading platform 110 is located above the second surface P2, the first surface P1 is a use surface, the second surface P2 is a non-use surface, and the first bearing structure 130 can load the rolled goods. During the return trip, the loading platform 110 can be turned over by means of the turning tool, so that the second surface P2 is located above the first surface P1, the first surface P1 is a non-use surface, the second surface P2 is a use surface, and the second bearing structure 140 can be loaded with flat goods.

Second preferred embodiment

Referring to fig. 4 and 5, a rack type package 200 according to a second preferred embodiment will be described. As shown in fig. 4 and 5, the rack container 200 has substantially the same structure and/or construction as the rack container 100 of the first preferred embodiment except for the first and second bearing structures 230 and 240. Accordingly, components and/or parts having substantially the same function as in the first preferred embodiment will be numbered identically herein and will not be described and/or illustrated in detail for the sake of brevity.

As shown in fig. 4, the first load bearing structure 230 is configured as a first roll cargo recess 231. As shown in fig. 5, the second carrying structure 240 is configured as a second rolled good recess 241. Wherein the shape and/or number of the first roll goods recesses 231 is different from that of the second roll goods recesses 241. Optionally, the number of the first roll good recesses 231 is different from the number of the second roll good recesses 241. For example, the number of the first roll good grooves 231 is less than the number of the second roll good grooves 241. In this case, the first bearing structure 230 may further include a first additional bearing plane 232. The first additional load bearing surface 232 is substantially flat for loading flat goods. The first roll goods recess 231 may be arranged between the first additional load bearing planes 232. In the illustrated embodiment, one first roll goods recess 231 is provided and is located between two first additional load bearing planes 232.

The second rolled goods recess 241 has a size in the length direction different from that of the first rolled goods recess 231, so that the second goods and the first goods having different diameters in the rolled shape can be transported, respectively. The second rolled goods recess 241 may be provided in two or more, and may have different or the same size from each other. Preferably, two or more second rolled goods recesses 241 have different sizes along the length direction of the bottom frame 120 for carrying rolled goods with different diameters.

The respective groove bottoms of the first rolled good groove 231 and the second rolled good groove 241 are staggered in the horizontal direction. The bottom frame 120 of this example embodiment may have substantially the same dimensions as the bottom frame 120 of the rack container 100.

In the rack container 200 of the present embodiment, for example, during the outward movement, the loading platform 210 is disposed such that the first surface P1 is located above the second surface P2, the first surface P1 is a use surface, and the second surface P2 is a non-use surface, so that the first bearing structure 230 can simultaneously load flat goods and rolled goods within a certain diameter range. During the return trip, the loading platform 210 can be turned over by means of the turning tool, so that the second surface P2 is located above the first surface P1, the first surface P1 is a non-use surface, the second surface P2 is a use surface, and the second bearing structure 240 can load the rolled goods with different diameters and a larger number relative to the first bearing structure 230.

Third preferred embodiment

Next, a rack type package 300 according to a third preferred embodiment will be described with reference to fig. 6 and 7. As shown in fig. 6 and 7, the rack container 300 has substantially the same structure and/or configuration as the rack container 100 of the first preferred embodiment except for the first and second load bearing structures. Accordingly, components and/or parts having substantially the same function as in the first preferred embodiment will be numbered identically herein and will not be described and/or illustrated in detail for the sake of brevity.

The first load bearing structure 330 is configured as an a-frame support structure. The a-frame support structure includes an a-frame 331 pivotally connected to the base frame 120 between an upright, unfolded position (fig. 6) and a horizontal, folded position (fig. 7). The a-frame 331 is foldable such that the a-frame 331 can carry plate-like goods such as glass in the unfolded position, and the a-frame 331 can not protrude out of the plane defined by the corner pieces 122 in the folded position, so as to facilitate stacking, turning, etc. of the rack container 300. In other words, the A-frame 331 is folded to lie inside the plane defined by the corner pieces 122. The a-frame support structure further includes receiving slots 332 recessed inwardly from the first surface P1 to receive the a-frame 331 in the folded position. This allows the a-frame 331 to be folded to lie inside the plane of the first surface P1.

In the illustrated embodiment, the a-frame support structure may further include a second additional bearing plane 333. The second additional bearing plane 333 is formed by a plate-like member connected with the bottom side beam 124, the bottom end beam 125. The second additional bearing plane 333 is located generally in the first surface P1. The receiving groove 332 is recessed inward from the second additional bearing plane 333, so that the second additional bearing plane 333 can bear flat goods when the a-frame 331 is in the folded position. Alternatively, the bottom of the receiving groove 332 is formed in a flat surface.

In one embodiment of the a-frame 331, the a-frame 331 may be located inside the bottom side member 124 and connected to the bottom frame 120 via the bottom of the receiving groove 332. Another embodiment of the a-frame 331 is that the bottom side beam 124 may be provided with an opening at a position corresponding to the a-frame 331. The a-frame 331 can pass through this opening during the unfolding and folding processes. In still another embodiment of the a-frame 331, the a-frame 331 is retractable in a width direction of the base frame 120. In other words, the size of the a-frame 331 in the width direction of the base chassis 120 may be changed to enable the switching of the two positions.

Further, the second load bearing structure (not shown) may be configured as a rolled goods recess to load rolled goods.

In the rack container 300 of the present embodiment, for example, during the outward movement, the loading platform 310 is disposed such that the first surface P1 is located above the second surface P2, the first surface P1 is a use surface, the second surface P2 is a non-use surface, and the a-frame 331 is in the extended position to load the plate-like cargo. During the return stroke, the a-frame 331 is folded into the receiving groove 332. One way is that the loading platform 310 can be turned over by means of the turning tool, so that the second surface P2 is located above the first surface P1, the first surface P1 is a non-use surface, the second surface P2 is a use surface, and the second bearing structure can be loaded with rolling goods. Alternatively, the loading platform 310 may not be overturned, and the flat goods may be loaded by means of the second additional loading plane 333.

Fourth preferred embodiment

Next, a rack type package 400 according to a fourth preferred embodiment will be described with reference to fig. 8 and 9. As shown in fig. 8 and 9, the rack container 400 has substantially the same structure and/or construction as the rack container 100 of the first preferred embodiment except that the coupling rods 401 are further provided. Accordingly, components and/or parts having substantially the same function as in the first preferred embodiment will be numbered identically herein and will not be described and/or illustrated in detail for the sake of brevity.

The rack container 400 further includes a coupling rod 401 coupled with the coupling hole 121. The coupling rod 401 is detachably coupled to the coupling hole 121 from above the bottom chassis 120. In the illustrated embodiment, the coupling rods 401 are shown to include four, respectively connected with the coupling holes 121 of the four corner pieces 122 located above. Specifically, the hitch bar 401 includes a connected end and a free end. The connecting end is matched with the coupling hole 121, and the free end is provided with a coupling rod angle piece 402 with a coupling hole. The rack container 400 may be stacked, suspended, etc. by means of the hanger bar corner pieces 402.

Fig. 8 shows a first connection mode of the coupling rod 401. The coupling rods 401 can be coupled with the four coupling holes 121 formed at the first surface P1, thereby facilitating stacking, ceiling-hanging, etc. of the rack container 400 when the first load-bearing structure 130 is loaded with cargo. Fig. 9 shows a second connection of the coupling rod 401. The coupling rods 401 can be coupled with the four coupling holes 121 formed at the second surface P2, thereby facilitating stacking, ceiling-hanging, etc. of the rack container 400 when the second load-bearing structure 140 is loaded with cargo.

Although the illustrated embodiment shows that the loading platform of the rack container 400 is the same as the loading platform 110 of the first preferred embodiment, in an embodiment not shown, the loading platform of the rack container 400 may be substantially the same as the loading platform 210 of the second preferred embodiment or the loading platform 310 of the third preferred embodiment.
