Description

Technical Field

[0001] The utility model belongs to the technical field of ship engineering machinery, and in particular relates to a steel cushion structure used for a marine structure transport ship. Background Art

[0002] With the rapid development of the offshore oil industry, marine structures are becoming increasingly large, complex and diversified. After the construction of marine structures on land is completed, they need to be loaded onto ships by transport vehicles or dragging and sliding according to the form, scale and weight of the marine structures. Usually, large-sized and large-tonnage marine structures are mostly loaded onto ships by dragging and sliding, that is, the marine structure begins to be built on the slideway, and a concrete slider is generally laid on the slideway as the foundation of the structure. Steel plates, Teflon, wooden blocks and module support frames are laid from bottom to top on the concrete slider. The structure is smoothly slid from land to the transport barge by traction machinery and jack-assisted pushing. This method can reduce the deformation of the structure during transportation, reduce the risk and cost of loading, and is highly efficient. Therefore, dragging and sliding loading has also become a common practice for large marine structure transport ships.

[0003] At present, the key factor restricting the sliding loading method is the bearing capacity of the slider itself under the structure, especially at the front of the dock, where the slider bears the greatest pressure. The concrete slider is limited by the material properties, and its bearing capacity and stiffness are difficult to meet the requirements.

[0004] When using steel concrete piers, the bearing capacity is improved to a certain extent, but there are some shortcomings such as the difficulty in reinforcing and repairing concrete components, heavy weight, and low utilization rate. In addition, the concrete slider has a long construction period, heavy weight, and is not easy to carry. Therefore, steel piers can be used as sliders to improve the above shortcomings, but ordinary steel piers are difficult to meet higher bearing capacity requirements. In actual use, steel piers are often broken and deformed due to factors such as pressure resistance, which leads to greater safety hazards during the sliding loading process. Utility Model Content

[0005] Based on the above background, the purpose of the utility model is to provide a steel cushion structure for a marine structure transport ship.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0045] Example 1

[0046] like Figure 1-4 As shown, a steel cushion structure for a marine structure transport ship comprises a steel cushion top plate 1 and a steel cushion bottom plate 2. The steel cushion top plate 1 and the steel cushion bottom plate 2 are rectangular in shape and have the same size.

[0047] A sandwich reinforcement structure is arranged between the steel pad top plate 1 and the steel pad bottom plate 2; the sandwich reinforcement structure is welded between the steel pad top plate 1 and the steel pad bottom plate 2 to increase the compressive strength thereof and improve the stability of the structure, such as the tensile strength thereof.

[0048] The sandwich reinforcement structure includes a web mechanism, which includes a plurality of first webs 3 arranged side by side; the first webs 3 are fixedly connected between the steel pad top plate 1 and the steel pad bottom plate 2, and at the same time, the web mechanism also includes a plurality of second webs 4 arranged at intervals up and down; the second webs 4 are welded between the steel pad top plate 1 and the steel pad bottom plate 2.

[0049] Specifically, according to the existing welding method, the first web 3 and the second web 4 are welded at a groove design to ensure the tightness of the welding. At the same time, the first web 3 is a full-length method, and after welding, the second web 4 is divided into multiple sections by the first web 3. Therefore, the first web 3 and the second web 4 are welded in a cross-shaped manner.

[0050] In this way, a cross-shaped reinforcement structure is formed between the steel pad top plate 1 and the steel pad bottom plate 2. The advantage of this structural design is that a sandwich reinforcement structure is formed between the steel pad top plate 1 and the steel pad bottom plate 2. This reinforcement structure greatly improves the compressive resistance of the steel pad top plate 1 and the steel pad bottom plate 2. At the same time, it increases the deformation resistance of the entire device. Specifically, in high-load towing operations, the above structure can improve the deformation resistance.

[0051] The length of the first web 3 is greater than that of the second web 4 , and the length of the first web 3 is equal to the width of the steel pad top plate 1 and the steel pad bottom plate 2 .

[0052] The first webs 3 are arranged in parallel; the second webs 4 are arranged in parallel. The first webs 3 are distributed equidistantly; the second webs 4 are distributed equidistantly. Specifically, the first webs 3 and the second webs 4 are distributed equidistantly with the center lines of the steel pad top plate 1 and the steel pad bottom plate 2 as the reference line. In this way, the force is ensured to be uniform.

[0053] In actual working process, holes are opened on the second web 4 to reduce the amount of material used. However, in order to ensure the stability of the entire device, no holes are opened on the second web 4 located at the center (the second web 4 at the center bears a larger tensile load).

[0054] Example 2

[0055] like Figure 1-5 As shown, in order to further improve the compressive load resistance of the entire device, the sandwich reinforcement structure also includes a rib plate mechanism for increasing the stability of the web mechanism.

[0056] Specifically, the rib plate mechanism includes a plurality of pairs of first rib plate components spaced apart from each other in the upper and lower parts; the rib plate mechanism also includes a plurality of pairs of second rib plate components spaced apart from each other in the left and right parts.

[0057] Each pair of first rib plate assemblies includes two first rib plates 5 respectively welded to the bottom of the steel pad top plate 1 and the top of the steel pad bottom plate 2; the first rib plates 5 are welded to the web structure.

[0058] Specifically, by welding the first rib plate 5 assembly welded to the bottom of the steel pad top plate 1 and the steel pad bottom plate 2 to the web mechanism, the connection stability between the steel pad top plate 1, the steel pad bottom plate 2 and the web is further improved. Specifically, one end of the first rib plate 5 is welded to the corresponding steel pad top plate 1 and the steel pad bottom plate 2, and the other end is welded to the above-mentioned web side wall. In this way, the connection is further strengthened through the first rib plate 5. The entire sandwich reinforcement structure is strengthened and connected to the above-mentioned steel pad top plate 1 and steel pad bottom plate, which increases the deformation resistance and pressure resistance during the high-pressure load process.

[0059] Similarly, each pair of second rib plate assemblies includes two second rib plates 6 welded to the bottom of the steel pad top plate 1 and the top of the steel pad bottom plate 2 respectively; the second rib plate 6 is welded to the web structure. Specifically, one end of the second rib plate 6 is welded to the corresponding steel pad top plate 1 and steel pad bottom plate 2, and the other end is welded to the above-mentioned web. In this way, the connection is further strengthened through the first rib plate 5. The entire sandwich reinforcement structure is strengthened and connected to the above-mentioned steel pad top plate 1 and steel pad bottom plate to increase the deformation resistance and increase the pressure resistance during the high-pressure load process.

[0060] At the same time, both ends of the first rib plate 5 are chamfered to keep the ends smooth and avoid sharp corners from piercing construction workers during work.

[0061] The top of the steel pad top plate 1 is welded with a plurality of lug plates 7. According to the existing conventional method, the whole device is suspended and moved by a crane and a steel wire rope.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
