[0030] The present application is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present application, but are not intended to limit the present application in any form. It should be noted that, for those skilled in the art, without departing from the concept of the present application, several variations and improvements can also be made. These all belong to the protection scope of the present application.

[0031] The present application claims protection for a lashing bridge expansion device, which includes an operating platform and a positioning structure.

[0032] The operating platform has one end connected to the lashing bridge and has an unfolded state and a folded state. When it is in the unfolded state, the other end is away from the lashing bridge and close to the target container.

[0033] Figure 1 A side schematic diagram showing a working state of an embodiment of a lashing bridge and an expansion device thereof of the present application; Figure 2 Shows Figure 1 A top view of the middle lashing bridge and its extension device; Figure 3 A top view of an embodiment of an operating platform is shown; Figure 4 A side view of one embodiment of a handling platform is shown.

[0034] like Figure 1As shown, one end (left end) of the operating platform 1 is connected to the lashing bridge 6. When it is in the unfolded state, the other end (right end) of the operating platform 1 is away from the lashing bridge 6 and close to the target container 3, which is convenient for the operator to walk onto the operating platform, approach the target container 3, and perform lashing, inspection and other operations on it. Especially when the target container 3 is a specific container such as a refrigerated container or a frozen container, more frequent inspections and operations may be required. The figure schematically shows the unfolded state of the operating platform 1 close to the target container 3. In fact, there may be a gap between the two to facilitate the folding of the operating platform.

[0035] like Figure 2 and Figure 3 As shown, the operating platform 1 includes a bottom plate 12. The bottom plate 12 can be designed into various shapes such as rectangle, circle, triangle, etc. according to actual conditions. It is schematically designed as a rectangle in the figure. In some embodiments, the bottom plate 12 can also have multiple holes. The multiple holes provided on the bottom plate 12 can reduce the weight of the bottom plate and increase the friction force, making the operating platform 1 lighter and improving the safety of the operator's walking; in some embodiments, all or part of these holes can be set as through holes to facilitate water permeability, which is more suitable for the humid and watery environment on the ship, such as using a perforated steel plate as the bottom plate. In some embodiments, the bottom plate 12 can also directly use a patterned steel plate with good anti-slip effect or a grid plate with through holes as the bottom plate.

[0036] In some embodiments, the operating platform 1 includes a detachable or foldable railing 13, which is usually arranged around the bottom plate 12 of the operating platform 1, but a passage is reserved at the connection between the operating platform 1 and the lashing bridge 6. When the operating platform 1 needs to be switched to a stowed state, the railing can be disassembled or folded to reduce the volume of the operating platform 1 in the stowed state.

[0037] from Figure 1 and Figure 4 It can be seen that one end (left end) of the operating platform 1 is connected to the lashing bridge 6 via a connecting shaft 9, and the operating platform 1 can rotate around the connecting shaft 9 to switch between the unfolded state and the retracted state; when the operating platform 1 is in the retracted state, the other end is close to the lashing bridge 6. The connecting shaft 9 can be implemented in various ways, for example, an eye plate can be welded at the connection between the operating platform 1 and the lashing bridge 6, and the eye plate of the operating platform and the eye plate of the lashing bridge are connected by a pin shaft to form a rotating mechanism. Figure 1 The dotted line schematically shows the storage position 1-1 of an embodiment of the operating platform when it is folded. In this embodiment, when the operating platform 1 is folded, the other end (right end) rotates downward and approaches the lashing bridge 6. In some embodiments, when the operating platform 1 is folded, the other end can also rotate upward and approach the lashing bridge 6.

[0038] In some embodiments, when the operating platform 1 is in the retracted state, the other end can be fixed on the lashing bridge 6 . Figure 4 An implementation method is shown in which a panel 14 is provided at the bottom of the operating platform 1, and bolt holes 15 are provided on the panel 14. When the operating platform is folded up, the operating platform can be fixed to the lashing bridge 6 through the bolt holes 15 to prevent the operating platform 1 from hitting the lashing bridge or the container during the navigation of the ship. At the same time, the panel 14 provided at the bottom of the operating platform 1 can also play a buffering and protective role. The railing 13 can also be directly installed on the panel 14, or the railing base can be welded to the panel 14, and then the railing 13 is installed on the railing base. In other embodiments, the operating platform can also be fixed by other methods such as magnetic attraction, card slot buckle, etc. In some embodiments, when the operating platform 1 is in the unfolded state, the operating platform can also be fixed by various methods such as bolts, magnetic attraction, card slot buckle, etc. Figure 4 The bolt holes 16 for fixing the operating platform 1 in the unfolded state are shown. In some embodiments, the structural strength of the operating platform 1 can be increased by providing reinforcing ribs on the upper surface or lower surface of the bottom plate of the operating platform 1, such as welding one or more flat steel bars to the lower surface of the bottom plate 12 and / or the enclosure 14.

[0039] In some embodiments, the operating platform can also be folded in other ways. Figure 5 The schematic diagram of the operating platform being retracted into the lashing bridge through the telescopic rod is shown. As shown in the figure, the operating platform 1 is connected to the lashing bridge through the telescopic rod 28, and the operating platform 1 can be switched between the unfolded state and the retracted state by the telescopic rod; when the operating platform 1 is in the retracted state, it is partially or completely retracted into the lashing bridge 6. The figure shows a situation where the operating platform 1 is partially retracted into the lashing bridge 6. In some other embodiments, when the width of the lashing bridge in the first direction D1 is greater than or equal to the length of the operating platform in the first direction D1, the operating platform 1 can be fully retracted into the lashing bridge 6; or when the operating platform can shorten its length in the first direction D1 by folding or other means, it can also be fully retracted into the lashing bridge 6.

[0040] In some embodiments, the operating platform 1 can be extended or folded along the first direction D1 so as to adjust the distance between the operating platform 1 and the target container in the unfolded state and shorten the storage length in the folded state.

[0041] In some embodiments, Figure 2 As shown, one end of the operating platform 1 is connected to the lashing bridge 6 through a slide rail 10, so that the operating platform 1 can slide along the slide rail 10 and approach other target centralized boxes. In the figure, the slide rail 10 is arranged along the third direction D3, and the operating platform 1 can move along the slide rail 10 in the third direction D3; in some other embodiments, the slide rail 10 can also be arranged along the second direction D2 (see Figure 1), for example, the slide rail 10 is arranged on the lashing bridge column, so that the operating platform 1 can move in the second direction D2. In other embodiments, the slide rails can also be arranged in both the second direction D2 and the third direction D3, so that the operating platform can move more freely along the slide rails. In this way, the number of operating platforms can be reduced, and the packing can be performed more flexibly.

[0042] The lashing bridge expansion device of the present application also includes a positioning structure for fixing the position of the operating platform 1. The telescopic rod 28, bolt holes 15 and 16, and the slide rail 10 are also a type of positioning structure.

[0043] Figure 6 Shows Figure 1 Side view of the positioning structure. Figure 7 Shows Figure 6 Top view of the . Figure 1-2 and Figure 6-7 The positioning structure includes a support rod 21, and the support rod 21 can be made of various materials with sufficient strength, such as square steel, alloy, etc. As shown in the figure, one end of the support rod 21 is fixed to the deck 4 below the operating platform 1. In this case, some space needs to be reserved between the lower container 5 of the target container 3 and the lashing bridge 6 for setting the support rod 21. In other embodiments, one end of the support rod 21 can also be fixed to the container or the lashing bridge 6 below the operating platform 1. The position where one end of the support rod 21 is fixed can be selected according to actual conditions, such as welding a support elbow on the deck below the operating platform 1 or the existing corner 7 of the container below (such as Figure 6 222, 223 and 224 as shown), and weld a first panel 25 on the support elbow, so that one end of the support rod 21 is connected to the first panel 25. When the operating platform 1 is in the unfolded state, the other end of the support rod 21 can be directly connected to the bottom of the operating platform 1 and support the operating platform 1 from below; in some embodiments, the support rod 21 can also be in other ways, such as welding a second panel 26 at the other end of the support rod 21, and supporting the operating platform 1 through the second panel 26.

[0044] The support elbow 22 is also a part of the positioning structure, and can be in various forms such as a plate, a stick, a column, etc., and is arranged on the deck below the operating platform 1 or on the container below to support the support rod 21. In addition to the above-mentioned support elbows 222, 223, and 224, other support elbows can also be arranged. Figure 1 and Figure 6 The supporting elbow 221 etc. in the figure can play a role of supporting and balancing.

[0045] In some embodiments, there is also a positioning component 11 (such as Figure 4When the operating platform 1 is in the unfolded state, the other end of the support rod 21 is connected to the positioning component 11 to support the operating platform 1 from below. Figure 6 The other end of the support rod 21 is connected to the second panel 26 Figure 4 The positioning member 11 of the operation platform 1 supports the operation platform 1. The positioning member 11 and the other end of the support rod 21 should be able to cooperate with each other, for example, in some other embodiments, various methods such as groove / protrusion cooperation, slot / buckle cooperation, magnetic suction cooperation, etc. can also be adopted.

[0046] In some embodiments, the support rod 21 is detachable. In this way, when the support rod 21 is not needed, it can be disassembled and stored, such as stored between the columns of the lashing bridge 6, which is also convenient for supporting the operating platform 1 in different positions.

[0047] In other embodiments, one end of the support rod 21 is fixed to the deck below the operating platform 1, the container below, or the lashing bridge 6 through a fixed shaft 24, and the support rod 21 can rotate around the fixed shaft 24. Figure 8 A side schematic diagram of another embodiment of the lashing bridge and its expansion device of the present application in working state is shown. In the figure, one end of the support rod 21 is fixed on the lashing bridge 6, and the support rod 21 adopts a retractable design, so that the length of the support rod 21 is variable, and it can contact with the operating platform 1 through multiple different contact points and provide supporting force, which is more flexible and convenient to cooperate with the above-mentioned retractable or foldable operating platform 1; in addition, the support rod 21 can also be retracted under the lashing bridge 6 by rotation.

[0048] In some embodiments, the positioning structure may include a suspension rope 27 or a suspension rod, one end of which is connected to the operating platform 1 and the other end is connected to the tying bridge 6; when the operating platform 1 is in the unfolded state, the suspension rope 27 or the suspension rod pulls the operating platform 1 from above. Fig. 9 A side schematic diagram of another embodiment of the lashing bridge and its expansion device of the present application in working state is shown. As can be seen from the figure, since the sling 27 pulls the operating platform 1 from above, no space needs to be reserved under the operating platform 1, and a larger container can be configured. The storage position 1-1 when the operating platform 1 is retracted upward is schematically drawn with dotted lines in the figure, and the retracting of the sling 27 or the sling rod can switch the operating platform 1 between the deployed state and the retracted state.

[0049] In some embodiments, the positioning structure may also be used in combination with multiple methods, such as using two or more of a hanging rope, a hanging rod, a support rod, a slide rail, and a telescopic rod.

[0050] The present application also discloses a lashing bridge 6, comprising the lashing bridge expansion device described in the above embodiments.
