Description

Technical Field

[0001] The present invention relates to the technical field of ships, and particularly relates to a cargo retaining bulkhead structure for a deck barge. Background Art

[0002] A deck barge refers to a non-self-propelled barge that loads goods on the deck. As Figure 1 shown, longitudinal cargo retaining bulkheads 101 and transverse cargo retaining bulkheads 102 are arranged on the deck 100 of the deck barge. The goods exert a lateral extrusion on the cargo retaining bulkheads, which is its local strength. The conventional cargo retaining bulkheads are continuous and unbroken in the longitudinal direction of the hull, which will cause them to fully participate in the total longitudinal bending deformation of the hull and will bear a large longitudinal bending stress (i.e., the total strength stress) during ship navigation. For the cargo retaining bulkhead structure, the structural dimensions required to meet the local strength requirements are small, while the structural dimensions required to meet the total strength requirements are large.

[0003] Since the longitudinal cargo retaining bulkhead is connected to the ship deck and is longitudinally continuous and unbroken, this will cause the longitudinal cargo retaining bulkhead to participate in the total longitudinal bending deformation together with the hull girder, so a large longitudinal bending stress will be generated on the longitudinal cargo retaining bulkhead. To make the structural stress value less than the allowable value required by the specification, it is necessary to increase the member size of the cargo retaining bulkhead structure. This makes the structural dimensions of the longitudinal cargo retaining bulkhead tend to be large, thus increasing the steel weight of the hull itself, increasing the shipbuilding cost, and at the same time reducing the ship's cargo capacity. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned defects existing in the prior art and provide a cargo retaining bulkhead structure for a deck barge.

[0005] The present invention solves the above technical problem through the following technical solutions:

[0006] A cargo retaining bulkhead structure for a deck barge, which includes a longitudinal cargo retaining bulkhead fixed to the ship deck. The longitudinal cargo retaining bulkhead includes a plurality of longitudinal bulkhead segments, and adjacent longitudinal bulkhead segments are not directly connected; the longitudinal bulkhead segments are discontinuously distributed on the ship deck; a bulkhead joint member is provided between adjacent longitudinal bulkhead segments; the end of the longitudinal bulkhead segment includes a vertical end and an inclined end, the inclined end is connected to the bottom of the vertical end, the inclined end extends obliquely towards the outside of the longitudinal bulkhead segment, and the bottom of the inclined end is connected to the ship deck; the bulkhead joint member includes a joint member body, the end of the joint member body is adapted to the end of the longitudinal bulkhead segment, there is a hollow part between the end of the longitudinal bulkhead segment and the end of the joint member body, and the joint member body is fixedly provided with a covering plate that can cover the hollow part; the covering plate extends on the longitudinal bulkhead segment.

[0007] Preferably, the inclined end is in the shape of an inward concave arc.

[0008] Preferably, a first reinforcing rib is fixedly provided at the end of the longitudinal baffle segment.

[0009] Preferably, the joint body includes a joint panel and a joint reinforcing plate, and the joint reinforcing plate is fixedly provided on the outer surface of the joint body.

[0010] Preferably, the joint reinforcing plate includes a first reinforcing plate distributed horizontally, and the first reinforcing plate is connected to the joint body by welding.

[0011] Preferably, the joint reinforcing plate further includes a second reinforcing plate distributed vertically, and the second reinforcing plate is connected to the joint body by welding.

[0015] Preferably, there are two longitudinal cargo retaining baffles, and the two longitudinal cargo retaining baffles are respectively located on both sides of the ship deck.

[0016] The beneficial effects of the present invention are as follows: In the cargo retaining baffle structure of the deck barge of the present invention, since the adjacent longitudinal baffle segments are not directly connected, that is, the longitudinal cargo retaining baffle has discontinuity, therefore, the longitudinal cargo retaining baffle does not participate in the longitudinal bending deformation of the hull girder, so the longitudinal bending stress on the baffle structure is basically zero. Since the longitudinal cargo retaining baffle does not participate in the longitudinal bending deformation of the hull, there is no need to consider the overall strength requirements of the longitudinal cargo retaining baffle, and the component size can be reduced. In this way, the purpose of reducing the weight of the hull structure and saving the construction cost is achieved. In the cargo retaining baffle structure of the deck barge of the present invention, the longitudinal cargo retaining baffle is manufactured in multiple parts, which also facilitates the installation and transportation of the product.

[0024] Next, a preferred embodiment is given, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0025] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a deck barge cargo retaining bulkhead structure includes a longitudinal cargo retaining bulkhead 210 fixedly connected to the ship deck 200. The longitudinal cargo retaining bulkhead includes a plurality of longitudinal bulkhead segments 220, and adjacent longitudinal bulkhead segments 220 are not directly connected; the longitudinal bulkhead segments 220 are discontinuously distributed on the ship deck; a bulkhead joint member 230 is provided between adjacent longitudinal bulkhead segments 220.

[0026] The end of the longitudinal bulkhead segment 220 includes a vertical end 221 and an inclined end 222. The inclined end 222 is connected to the bottom of the vertical end 221, the inclined end 222 extends obliquely towards the outside of the longitudinal bulkhead segment, and the bottom of the inclined end 222 is connected to the ship deck.

[0027] The inclined end 222 is in the shape of an inward concave arc. A first reinforcing rib 261 is fixedly provided at the end of the longitudinal bulkhead segment 220.

[0028] The bulkhead joint member 230 includes a joint member body 240, and the end of the joint member body 240 is adapted to the end of the longitudinal bulkhead segment 220.

[0029] There is a hollow part between the end of the longitudinal bulkhead segment 220 and the end of the joint member body 240, and the joint member body 240 is fixedly provided with a covering plate 250 that can cover the hollow part.

[0030] The covering plate 250 extends on the longitudinal bulkhead segment. The covering plate 250 is provided on the inner side of the longitudinal bulkhead segment.

[0031] The joint member body 240 includes a joint member panel 241 and a joint member reinforcing plate, and the joint member reinforcing plate is fixedly provided on the outer surface of the joint member body.

[0032] The joint member reinforcing plate includes a first reinforcing plate 242 distributed horizontally, and the first reinforcing plate 242 is welded to the joint member body 240.

[0033] The joint reinforcement plate further includes a second reinforcement plate 243 vertically distributed, and the second reinforcement plate 243 is welded to the joint body 240.

[0034] A second reinforcing rib 262 is fixedly provided at the end of the joint body 240, and the second reinforcing rib 262 is welded to the outer surface of the joint body.

[0035] The bridging plate 250 is fixedly provided on the inner surface of the joint body 240, and the bridging plate 250 is welded to the joint body 240.

[0036] There are two longitudinal cargo retaining fences 210, and the two longitudinal cargo retaining fences are respectively located on both sides of the ship deck 200.

[0037] In the cargo retaining fence structure of the deck barge of the present invention, a fence joint is provided between the longitudinal fence segments, and the bridging plate on the fence joint covers the hollow part between the longitudinal fence segments and the fence joint, and the bridging plate is arranged on the inner surface of the longitudinal fence segment. In this way, when the longitudinal cargo retaining fence is loaded with goods, the goods will not leak from the hollow part to the outside of the longitudinal cargo retaining fence.

[0038] The bridging plate is only fixedly connected to the joint body of the fence joint, and the bridging plate is not fixedly connected to the longitudinal fence segment. The bridging plate and the longitudinal fence segment are only lapped. In this way, the purpose that the adjacent longitudinal fence segments are not directly connected is achieved, and it does not affect the loading of goods inside the longitudinal cargo retaining fence.

[0039] In the cargo retaining fence structure of the deck barge of the present invention, since the adjacent longitudinal fence segments are not directly connected, that is, the longitudinal cargo retaining fence has discontinuity, therefore, the longitudinal cargo retaining fence does not participate in the longitudinal bending deformation of the hull girder, and thus the longitudinal bending stress on the fence structure is basically zero.

[0040] In the cargo retaining fence structure of the deck barge of the present invention, the longitudinal cargo retaining fence does not participate in the longitudinal bending deformation of the hull, so the total strength requirement of the longitudinal cargo retaining fence does not need to be considered, and the member size can be reduced. In this way, the purpose of reducing the weight of the hull structure and saving the construction cost is achieved.

[0041] In the cargo retaining fence structure of the deck barge of the present invention, the longitudinal cargo retaining fence is manufactured in multiple parts, which also facilitates the installation and transportation of the product.

Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
