Abstract
Description
Technical Field
[0001] The utility model relates to the water transportation of steel coils, specifically to a steel coil loading bracket and a steel coil transport ship. Background Art
[0002] Taking steel billets as raw materials, after heating, they are made into strip steel by rough rolling mills and finishing mills. The strip steel is hot-pressed and cold-pressed into a coil shape, which is a steel coil, also known as a steel drum. A steel drum is a steel coil in the shape of a cylinder. The steel is hot-pressed and cold-pressed into a coil shape for storage and transportation, and can be used for various processing, such as being processed into steel plates, steel strips, etc. The formed coils are mainly hot-rolled coils and cold-rolled coils. Hot-rolled coils are processed products before the recrystallization of steel billets, and cold-rolled coils are subsequent processing of hot-rolled coils. The conventional weight of steel coils is about 15 - 30 tons, and they are generally used in the manufacture of ships, automobiles, trains, steel rails, steel bars for houses, steel bridges, steel pipes, and are widely used in engineering machinery equipment, boiler and container fittings, power equipment, mining equipment, machine tools, metallurgical equipment, coal mine machinery equipment, ships, forgings, power generation equipment and other fields.
[0003] For the long-distance transportation of a large number of steel coils, shipping is mostly adopted, which has the advantages of low freight, long transportation distance, large carrying capacity, etc.
[0004] As Figure 1 shown, the current method of shipping steel coils is as follows: lay a number of long wooden pads on the inner bottom plate and the inclined plates of the two side bottom holds of the ship, and then place the steel coils on the wooden pads 01. The steel coils are tied together with locking steel coils or steel wires. The loading of steel drums has dimensional requirements for the inner bottom plate, the inclined plates of the two side bottom holds of the ship and the stiffeners above them, which often play a decisive role in the dimensions, resulting in a high weight of the cargo ship loaded with steel drums. The lower part of the inner bottom plate and the inclined plates of the bottom holds of the ship consists of transverse plates, longitudinal plates and the stiffeners on the plates.
[0005] The load of the steel coil acts on the pads, and the load of the pads acts on the plates and stiffeners of the inner bottom plate, which has certain requirements for the thickness of the plates and the specifications of the stiffeners. For different numbers of steel coil loading layers, the weight of a single steel coil, the length of a single steel coil, and the number of pads, the required specifications of the plates of the inner bottom plate and the inclined plates of the bottom holds and the stiffeners are all different. Moreover, generally, compared with the loading condition, the steel coil loading condition has more stringent requirements for dimensions, that is, this condition generally has a decisive role in dimensions, which leads to the design of a cargo hold being initially designed for a certain steel coil loading specification, and the steel coil loading specification of the ship during later operation cannot exceed this specification. Therefore, this specification cannot be set too high and should be selected according to the actual situation, otherwise it will greatly increase the weight of the ship and reduce the operation economy. Due to the above reasons, it greatly affects the flexibility of the cargo ship to load steel drums, and due to this occasionally used steel coil loading condition, a considerable amount of weight waste is caused. Utility Model Content
[0006] Traditional steel coil loading requires additional increase in the specifications of the inner bottom plate, the hopper tank inclined plate and the upper frame, and the design is carried out with a certain specification of steel coil as the design parameter in the initial design stage. The steel coil loading specifications of the ship in later operation cannot exceed this specification.
[0007] The utility model only requires that a new type of steel coil loading bracket be arranged above the inner bottom plate before loading the steel coil. After being installed and fixed in place, the steel coil can be freely loaded. The loading specification of the steel coil drum is no longer used as an initial design parameter, thereby improving the flexibility of the structural design; the flexibility and loading capacity of the steel coil drum loading are greatly improved, so that the loading of the steel coil drum is only restricted by the ship load curve and the total longitudinal strength.
[0008] The specific plan is as follows:

Both the first steel coil bracket frames and the second steel coil bracket frames are T-shaped steels, and a distance is left between the first steel coil bracket frames and the inner bottom plate.
[0012] Furthermore, the height of the longitudinal vertical plate of the steel coil bracket is 300 to 500 mm.
[0013] Further, a cushion block is provided between the inner side of the side plate of the steel coil bracket and the steel coil.
[0014] Further, the top surface height of the steel coil placed on the steel coil bracket plate is approximately equivalent to the top surface height of the side plate of the steel coil bracket.

A steel coil loading bracket provided by the present utility model is installed with a plurality of steel coil loading brackets (such as Figure 3 ) along the ship length direction on the inner bottom plate 4 of the ship's cabin. A plurality of longitudinal girders 5 are provided along the ship length direction on the lower surface of the inner bottom plate 4, and a plurality of brackets 8 are provided along the ship width direction on the lower surface of the inner bottom plate 4.
[0027] Each steel coil loading bracket is a horizontally placed "I"-shaped bracket (such as Figure 4 , Figure 4 using an omitted drawing method, with the middle components hidden). The transverse width of the steel coil loading bracket is equivalent to the width of the inner bottom plate 4. The steel coil loading bracket includes a steel coil bracket plate 1 horizontally arranged along the ship width. At both ends of the steel coil bracket plate 1, steel coil bracket side plates 6 are vertically arranged. A row of steel coils is placed on the steel coil bracket plate 1 between the steel coil bracket side plates 6.
[0028] A distance is left between the steel coil bracket plate 1 and the inner bottom plate 4. A plurality of horizontally and vertically staggered steel coil bracket longitudinal vertical plates 3 and steel coil bracket transverse vertical plates 7 are provided on the lower surface of the steel coil bracket plate 1. A plurality of steel coil bracket longitudinal vertical plates 3 parallel to the ship length direction are provided in the ship width direction, and a plurality of steel coil bracket transverse vertical plates 7 parallel to the ship width direction are provided in the ship length direction. The steel coil bracket longitudinal vertical plates 3 and the steel coil bracket transverse vertical plates 7 are vertically aligned with the longitudinal girders 5 and the brackets 8 respectively in the vertical direction. The lower ends of the steel coil bracket side plates 6, the steel coil bracket longitudinal vertical plates 3, and the steel coil bracket transverse vertical plates 7 all contact the upper surface of the inner bottom plate 4.
[0029] A plurality of first steel coil bracket stiffeners 2 parallel to the steel coil bracket longitudinal vertical plates 3 are provided on the lower surface of the steel coil bracket plate 1. Second steel coil bracket stiffeners 12 are vertically arranged on the outer side surfaces of the steel coil bracket side plates 6. Both the first steel coil bracket stiffeners 2 and the second steel coil bracket stiffeners 12 are T-shaped steel materials, and a distance is left between the first steel coil bracket stiffeners 2 and the inner bottom plate 4.
[0030] In an optional embodiment, the height of the steel coil bracket longitudinal vertical plate 3 is 300 - 500 mm.
[0031] In an optional embodiment, a cushion block 9 is provided between the inner side of the steel coil bracket side plate 6 and the steel coil.
[0032] In an alternative embodiment, the top surface height of the steel coil placed on the steel coil support plate 1 is approximately equivalent to the top surface height of the side plates 6 of the steel coil support.
[0033] In an alternative embodiment, the rows of steel coils placed on the steel coil support plate 1 are fixedly connected by wire ropes.
[0034] In an alternative embodiment, a number of steel coil loading brackets are installed on the inner bottom plate 4 of the steel coil transport ship along the ship length direction.
[0035] The utility model consists of four parts.
[0036] The first part is the horizontally arranged steel coil support plate 1, with the first steel coil support stiffeners 2 arranged on the lower side, and this part is divided into sections in the ship length direction;
[0037] The second part is the longitudinally arranged steel coil support longitudinal vertical plate 3 (i.e., the steel coil support longitudinal vertical plate 3 is the ship length plate), whose lower end is aligned with the longitudinal girder 5 under the inner bottom plate 4. To ensure the alignment with the longitudinal girder 5 under the inner bottom plate 4, the steel coil support longitudinal vertical plate 3 should have an appropriate thickness, and the height can be relatively low, such as 300 - 500 mm. This part is divided into sections in the ship length direction;
[0038] The third part is the outermost longitudinally arranged steel coil support side plate 6. To prevent the steel coil drum from moving laterally, the steel coil support side plate 6 should have a certain height, and a number of longitudinal second steel coil support stiffeners 12 are arranged vertically on the outer side surface of the steel coil support side plate 6. This part is divided into sections in the ship length direction;
[0039] The fourth part is the transversely arranged steel coil support longitudinal vertical plate 7 (i.e., the steel coil support longitudinal vertical plate 7 is the ship width plate), whose lower end is aligned with the bracket 8 under the inner bottom plate. To ensure the alignment with the bracket 8 under the inner bottom plate, the steel coil support longitudinal vertical plate 7 should have an appropriate thickness, and the height can be relatively low, such as 300 - 500 mm. These four parts together form the steel coil loading bracket of the utility model.
[0040] For refitted ships or newly built ships, the new steel coil loading bracket can be used to load any number of steel coils with different specifications. Specifically designed for a certain cargo ship, the size of the steel coil bracket plate 1 is the same as that of the inner bottom plate of the ship, the spacing between the longitudinal vertical plates 3 of the steel coil bracket is the same as the spacing of the longitudinal girder 5 of the ship, and the spacing between the transverse vertical plates 7 of the steel coil bracket and the bracket 8 of the ship is the same. First, make the steel coil loading bracket according to the above principles. Usually, it can be stacked at the dock or in the idle area of the ship. When loading the steel coil drum, it can be lifted into the inner bottom plate of the cargo hold by a crane. After being installed and fixed in place, the free loading of the steel coil can be realized. The row of steel coils 13 are connected by steel wires 11 to prevent them from rolling. A braking member 9 is provided between the inner side of the side plate 6 of the steel coil bracket and the side steel coil 11.
[0041] In practical applications, since the action of the steel coil drum on the plates and ribs of the inner bottom plate 4 and the inclined plate 10 of the bottom hold is transformed into the action on the longitudinal girder 5 and the bracket 8, the plates and ribs of the inner bottom plate 4 and the inclined plate 10 of the bottom hold do not increase in size due to the steel coil drum, reducing the structural weight of the cargo hold; the loading specifications of the steel coil drum are no longer used as the initial design parameters, improving the flexibility of the structural design; greatly improving the flexibility and loading capacity of the steel coil loading, so that the loading of the steel coil drum is only restricted by the ship's deadweight curve and longitudinal strength.

[0044] 2. Strong flexible adaptability: Through the steel coil loading bracket of the present utility model, the ship can adapt to the loading requirements of different specifications of steel coils, improving the transportation efficiency and flexibility of the ship.
[0045] 3. Reducing structural burden: The design of the steel coil loading bracket transfers the pressure of the steel coil drum on the inner bottom plate and the inclined plate of the bottom hold to the longitudinal girder and the bracket, reducing the burden on the cabin structure and extending the service life of the ship.
[0046] 4. Increasing the loading capacity: Due to the design of the steel coil loading bracket, the ship can load more steel coils, improving the loading capacity of the ship and thus increasing the economic benefits.
[0047] 5. Facilitating installation and disassembly: The steel coil loading bracket of the present utility model can be easily hoisted and installed by equipment such as a crane, and is also easy to disassemble and store, facilitating the rapid conversion of the ship between different loading requirements.
[0048] 6. Safe and reliable: Through the design and use of the steel coil loading bracket, the stable loading of steel coils in the cabin can be ensured, avoiding potential safety hazards caused by the sliding or rolling of steel coils, and improving the safety of ship transportation.
[0049] 7. Environmentally friendly and energy-saving: The steel coil loading bracket of the present utility model is made of lightweight materials, reducing the self-weight of the ship, thereby reducing energy consumption and emissions, and meeting the requirements of environmental protection and energy conservation.
[0050] In summary, the present utility model provides a steel coil loading bracket, which has the advantages of reasonable structural design, strong flexible adaptability, reducing the structural burden, increasing the loading capacity, being convenient for installation and disassembly, being safe and reliable, and being environmentally friendly and energy-saving.
