Description

Technical Field

[0001] The present invention relates to the technical field of containers, and more particularly to an open-top container. Background Art

[0002] Open top container is a kind of container. Some large goods cannot pass through the container door, which gave rise to the emergence of open top container. The top of the open top container is open. It is an internationally used transportation equipment, generally suitable for loading some large machinery and equipment or bulk cargo.

[0003] Open top boxes are divided into hard top open top boxes and soft top open top boxes. The difference between the two lies in the form and material of the top cover; the top cover of the soft top box is mostly made of tarpaulin structure, which is windproof and rainproof, and is relatively light, and the process of disassembling and installing the soft top can be completed manually.

[0004] In order to fix the tarpaulin or other soft roof structure covering the top of the box, a circle of round holes is often set around the tarpaulin; correspondingly, a circle of round rings is set on the side of the top beam of the box body, and the round holes on the tarpaulin are put on the round rings on the top beam one by one, and then the steel wire rope is passed through the round rings one by one and fixed. In this way, the tarpaulin and other soft roof structures are fixed, which meets the requirements of sea transportation.

[0005] This soft-top fixing method that meets the requirements of sea transportation, namely the TIR Convention (Transport International Router), is too cumbersome and wastes work time when applied to other transportation environments (such as rail transportation, road transportation and other land transportation).

[0006] Therefore, an open top container is needed to at least partially solve the problems existing in the prior art. Summary of the invention

[0007] A series of simplified concepts are introduced in the Summary of the Invention, which will be further described in detail in the Detailed Description of the Invention.

[0037] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and do not limit the present invention.

[0038] First embodiment

[0039] like Figure 1 As shown, according to a first embodiment of the present invention, an open top container 100 is provided. The open top container 100 can be covered with a tarpaulin 10 to seal the top thereof. In other words, the open top container 100 is a soft top open top box.

[0040] The open top container 100 has a front end structure 110a and a rear end structure 110b including a top beam 111, a side structure 120 including a side plate 121 and a top side beam 122, and a bottom frame structure 130. Except for some differences in the size and arrangement position of some components, the above structure is substantially the same as the corresponding structure of a common container, and will not be described in detail here for the sake of brevity. For example, in the illustrated embodiment, the upper surface of the top side beam 122 is located below the upper surface of the top beam 111. The top of the open top container 100 of this embodiment is open, that is, it has an opening 101 on the top. Cargo can be loaded into the open top container 100 through the opening 101 by means such as hoisting. After the cargo is loaded, the opening 101 is covered with a tarpaulin 10 to seal it.

[0041] It is to be understood that the directional terms mentioned herein, such as "upper", "above", "lower", "below", "front", "rear", etc., are relative to the state in which the open top container 100 is normally placed upright. The "length direction" and "width direction" mentioned herein refer to the length direction and width direction of the open top container 100, respectively. The "inner side" mentioned herein refers to the side close to the center of the open top container 100, and the "outer side" refers to the side away from the center of the open top container 100.

[0042] A tarpaulin locking ring 102 is provided at the top of the open top container 100. Tarpaulin through holes 11 are provided around the tarpaulin 10. The outer size of the tarpaulin locking ring 102 is smaller than the aperture of the tarpaulin through hole 11, so that the tarpaulin through hole 11 can be mounted on the tarpaulin locking ring 102. Optionally, the tarpaulin locking ring 102 can correspond to the tarpaulin through hole 11 one by one. The tarpaulin through hole 11 can be rimmed with metal to prevent wear. Specifically, the open top container 100 includes a top side beam 122 (a part of the side structure 120) and a top end beam 111 (a part of the front end structure 110a / a part of the rear end structure 110b) arranged above the side plate 121. A supporting side beam 140 can be provided above the top side beam 122. The supporting side beam 140 can be fixed to the top side beam 122. A supporting end beam 150 can be provided on the inner side of the top end beam 111. The two ends of the support end beam 150 can be fixed to the top side beams 122 located on both sides. The tarpaulin locking ring 102 is arranged on the outer side of the support side beam 140 ( Figure 3 ) and the outer side of the supporting end beam 150 ( Figure 7). Optionally, the upper surface of the supporting side beam 140 and the upper surface of the supporting end beam 150 may be located at substantially the same horizontal plane, so that the tarpaulin 10 can neatly cover the open top container 100 .

[0043] like Figure 2 As shown, when the open top container 100 is used for sea transportation, the tarpaulin 10 needs to cover the opening 101, and the tarpaulin through holes 11 are sequentially sleeved to the corresponding tarpaulin locking rings 102 ( Figure 3 ), at which time the tarpaulin 10 is in a tensioned state, and then the rope 12 is passed through the tarpaulin locking rings 102 around the tarpaulin in sequence and the ends of the rope 12 are fixed. In this way, the tarpaulin 10 can be fixed by means of the tarpaulin locking rings 102 and the rope 12, so that the fixing method of the tarpaulin 10 can meet the requirements of sea transportation when used for sea transportation.

[0044] A rope-like locking ring 123 is provided at the side of the open top container 100. The rope-like locking ring 123 is provided below the tarpaulin locking ring 102. Specifically, both side panels 121 of the open top container 100 are provided with a plurality of rope-like locking rings 123. In the illustrated embodiment, the rope-like locking rings 123 are provided at the middle and upper part of the side panels 121 in the height direction and are arranged in a row in the length direction. Optionally, the number of rope-like locking rings 123 is less than the number of tarpaulin through holes 11. The first rope-like member 13 can be selected to pass through a portion of the tarpaulin through holes 11 to fix the tarpaulin 10, and this embodiment can reduce the fixing time of the tarpaulin 10 during land transportation.

[0045] like Figure 4 As shown, when the open top container 100 is used for land transportation, the tarpaulin 10 needs to cover the opening 101, and the portion of the tarpaulin 10 located at the top side beam 122 naturally droops ( Figure 5 ) and against the top side beam 122, then the first rope 13 is passed through the tarpaulin through hole 11 and tightened to make the tarpaulin 10 in a tightened state, and finally the first rope 13 is fixed to the rope lock ring 123. In the illustrated embodiment, the first rope 13 selects the tarpaulin through hole 11 that is closer at intervals, and it is not necessary to pass the first rope 13 through each tarpaulin through hole 11 to be fixed. This embodiment can not only achieve a good fixing effect, but also is simple and quick to operate, thereby improving the fixing efficiency of the tarpaulin 10. The land transportation in this article can be land transportation such as railway transportation and road transportation.

[0046] In the illustrated embodiment, the first rope-like member 13 includes a Y-shaped rope-like member for connecting the middle tarpaulin through hole 11 and a straight rope-like member for connecting the end tarpaulin through holes 11. Specifically, the tarpaulin 10 is fixed by a plurality of Y-shaped rope-like members and two straight rope-like members. Specifically, the top ends of the two branches are respectively connected to the corresponding tarpaulin through holes 11, and the bottom ends are connected and fixed to the rope-like member locking ring 123. In this embodiment, the shape of the first rope-like member 13 is not limited. For example, a straight rope-like member, a Y-shaped rope-like member, or a rope-like member of other shapes can also be selected separately.

[0047] The part (front and rear parts) of the tarpaulin 10 located at the top beam 111 can be fixed in a manner substantially the same as that used for sea transportation. Specifically, the tarpaulin through hole 11 of the tarpaulin 10 located at the top beam 111 is sequentially mounted on the tarpaulin locking ring 102 at the top beam 111, and then the second rope 14 separate from the first rope 13 is sequentially passed through the tarpaulin locking ring 102 and the end of the second rope 14 is fixed. In order to facilitate the fixing of the second rope 14, a fixing ring 124 is provided at the end of the side plate 121. The end of the second rope 14 can be locked to the fixing ring 124 ( Figure 7 ). Of course, the fixing ring 124 here can also be used to fix the end of the rope-like member when the open top container 100 is used for sea transportation. In other words, the fixing ring 124 can be used to fix the rope-like member when it is transported by sea or by land. In the illustrated embodiment, the fixing ring 124 is located above the outermost rope-like member locking ring 123 and the two rings are in a row.

[0048] When the tarpaulin 10 needs to be opened for unloading / loading of goods, the first rope-shaped members 13 need to be opened one by one, and the second rope-shaped member 14 needs to be opened. The two ends of the second rope-shaped member 14 can be opened and pulled out quickly, and the operation process is simple and quick.

[0049] Furthermore, if Figure 5 and Figure 6 As shown, when the open top container 100 is used for land transportation, the tarpaulin through hole 11 can be located below the upper surface F1 of the top side beam 122. And the tarpaulin through hole 11 is located above the rope-shaped member locking ring 123. It can be understood that here it means that the tarpaulin through holes 11 are all located below the upper surface F1 of the top side beam 122, and all located above the rope-shaped member locking ring 123. Specifically, the tarpaulin through hole 11 can preferably be located at a predetermined position B1, and the predetermined position B1 is located outside the top side beam 122 and below the upper surface F1 of the top side beam 122. In this way, it can be ensured that liquids such as rainwater on the outside of the tarpaulin 10 will not enter the upper surface F1 of the top side beam 122 through the tarpaulin through hole 11, and thus will not penetrate into the interior of the open top container 100, thereby improving the sealing of the open top container 100 and the safety of the cargo.

[0050] Optionally, return a reference Figure 1 and Figure 5 The supporting side beam 140 includes a supporting side beam outer surface F2 extending vertically and a groove 141 recessed inward from the supporting side beam outer surface F2. The tarpaulin locking ring 102 is disposed in the groove 141, and the distance from the lower edge of the supporting side beam outer surface F2 to the tarpaulin locking ring 102 is greater than the distance from the lower edge of the supporting side beam outer surface F2 to the upper surface F1 of the top side beam 122. Specifically, the size of the tarpaulin 10 (specifically the size along the width direction) should be sufficient to be able to be fitted onto the tarpaulin locking ring 102 on the one hand, and to be sufficient to ensure that the tarpaulin through hole 11 can be located below the upper surface F1 of the top side beam 122 after natural drooping on the other hand. As a result, the open top container 100 can be covered with the same tarpaulin 10 when it is used for sea transportation and when it is used for land transportation; in other words, the tarpaulin 10 can be used as a sea transportation tarpaulin or a land transportation tarpaulin.

[0051] In addition, the depth A1 of the groove 141 ( Figure 3 ) It should also meet the requirement that when used for sea transportation, liquids such as rainwater on the outside of the tarpaulin 10 will not enter the groove 141 and will not easily enter the inner side of the tarpaulin 10 through the tarpaulin holes 11, so as to avoid entering the inner side of the tarpaulin 10 through the tarpaulin holes 11 and penetrating upward into the box or causing the goods in the box to get damp and cause serious losses.

[0052] In the illustrated embodiment, Figure 5 As shown, the supporting side beam 140 includes a first square tube beam 142 connected to the top side beam 122 and a second square tube beam 143 disposed on the upper portion of the first square tube beam 142, and the second square tube beam 143 is located on the outer side of the first square tube beam 142 to form a groove 141. The second square tube beam 143 can be welded to the outer side of the first square tube. In an embodiment not shown, the supporting side beam 140 can be an integrally formed inverted L-shaped tube having a groove 141. The inverted L-shaped tube can be hollow.

[0053] The rope-like member in this embodiment can be a rope of common material, or can be a steel wire rope. Specifically, the rope-like member used to fix the tarpaulin 10 during sea transportation is a steel wire rope, and the rope-like member used to fix the tarpaulin 10 during land transportation is a common rope.

[0054] Second embodiment

[0055] Reference below Figures 8 to 11 An open top container 200 according to a second embodiment of the present invention is described. The open top container 200 has substantially the same structure and / or construction as the open top container 100 of the first embodiment except for the supporting side beams 240, and therefore, elements having substantially the same functions as those in the first embodiment will be numbered the same herein and will not be described and / or illustrated in detail herein for the sake of brevity.

[0056] The supporting side beam 240 has a vertically extending supporting side beam outer surface F22, and the tarpaulin locking ring 202 is arranged on the supporting side beam outer surface F22. Optionally, the tarpaulin locking ring 202 does not protrude from the vertically extending outer surface F3 of the top side beam 122. The supporting side beam 240 can be a square tube beam. In other words, the second square tube beam of the first embodiment is removed in this embodiment.

[0057] like Figure 8 and Fig. 9 As shown, when the open top container 200 is used for sea transportation, a sea tarpaulin 20a needs to be selected to cover the opening, and the through holes 21a of the sea tarpaulin are sequentially sleeved onto the corresponding tarpaulin locking rings 202. At this time, the sea tarpaulin 20a is in a tensioned state, and then the rope 12 is sequentially passed through the surrounding tarpaulin locking rings 202 and the end of the rope 12 is fixed to the fixing ring 124.

[0058] like Fig.10 and Fig.11 As shown, when the open top container 200 is used for land transportation, it is necessary to select a land transportation tarpaulin 20b that is wider than the sea transportation tarpaulin 20a to cover the opening. The portion of the land transportation tarpaulin 20b located at the top side beam 122 can droop and cling to the top side beam 122, and the land transportation tarpaulin through hole 21b is fixed to the rope-shaped member locking ring 123 via the first rope-shaped member 13. The land transportation tarpaulin 20b is then put in a tensioned state by the first rope-shaped member 13, and the land transportation tarpaulin through hole 21b can be located below the upper surface F1 of the top side beam 122. And the land transportation tarpaulin through hole 21b is located above the rope-shaped member locking ring 123. Specifically, the land transportation tarpaulin through hole 21b is preferably located at a predetermined position B1, which is located outside the top side beam 122 and below the upper surface F1 of the top side beam 122.

[0059] The fixing method of the portion of the tarpaulin 10 located at the top end beam 111 of this embodiment is substantially the same as that of the first embodiment, and will not be described in detail for the sake of brevity.

[0060] Optionally, the outer surface F22 of the supporting side beam is spaced a predetermined distance from the outer surface F3 of the top side beam 122 so that when the open top container 200 is used for land transportation, the tarpaulin locking ring 202 does not abut against the land transportation tarpaulin 20b, or the tarpaulin locking ring 202 just contacts the land transportation tarpaulin 20b.

[0061] According to another aspect of the present invention, an open top container may include the above-mentioned tarpaulin.

[0062] The open top container provided by the present invention can be applied to various transportation environments, and can ensure the sealing of the box body while meeting the corresponding transportation requirements, and realize the needs of rapid fixing and rapid disassembly of the soft top (tarpaulin). The operation is simple and fast, time is saved, the production is simple, the cost is low, the safety is high, and the application range is wide.
