Description

Technical Field

[0001] The utility model relates to the field of marine transportation, in particular to a transport tooling for super-large loads. Background Art

[0002] With the market demand at home and abroad, the demand for oversized and overweight modules is increasing. At present, the transportation of modules of four to five thousand tons that can be seen on the market is increasing, and the heaviest can reach tens of thousands of tons. These modules usually have their own column feet, which need to be connected to the hull through the column feet during the sea consolidation process. Because the modules are very heavy, the force transmitted to the hull through the column feet is often very large. It is not uncommon for a column foot to have a support reaction force of two to three thousand tons, which easily poses a great challenge to the local strength of the hull. How to effectively disperse the column foot force without causing the hull to be unable to bear it locally is a major problem in the current shipping industry.

[0003] The existing technology is to design the buttress to be very long so as to cover the four ribs of the hull. However, since the buttress also has a certain rigidity, the ribs close to the cargo column foot will share most of the buttress load, while the ribs far from the column foot will hardly share the load effectively. If the buttress rigidity is designed to be very strong, it will be very wasteful and heavy, which is not conducive to on-site operations. Utility Model Content

[0011] Preferably, the transport tooling comprises two of the first force transmission pads, and the two first force transmission pads are respectively welded to the lower side of the upper sub-load beam.

[0021] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0022] Example 1

[0023] See also Figure 1 As shown, this embodiment provides a transport tool for super-large loads. The transport tool comprises an upper sub-beam 2, a first force transmission pad 3 and a lower sub-beam 4; the upper sub-beam 2 is used to receive the load transmitted by the cargo column foot 100; the first force transmission pad 3 is welded to the bottom of the upper sub-beam 2; the upper sub-beam 2 is placed on the lower sub-beam 4 through the first force transmission pad 3; the lower sub-beam 4 is arranged on the ship deck of the hull structure 1, and the hull structure 1 comprises a plurality of hull ribs 5.

[0024] In this embodiment, the transport tooling includes two first force transmission pads, two first force transmission pads (see Figure 2 As shown) are welded to the lower side of the upper sub-load beam 2 respectively. The two first force transmission pads are placed in the middle position of two adjacent hull rib positions. Specifically, the lower sub-load beam 4 is placed on the ship deck of the hull structure 1. The hull structure 1 includes a plurality of hull rib positions 5. In order to make the force of each hull rib position 5 uniform, the lower sub-load beam 5 is usually placed on two adjacent hull rib positions 5. At least two adjacent groups of such hull rib positions 5 are closest to the cargo column foot 100, or they can be two groups of adjacent two hull rib positions 5 separated by other hull rib positions 5. After determining the position of the lower sub-load beam 4, the lower sub-load beam 4 is fixed to the ship deck with a rib plate. The upper sub-load beam 2 welded with two first force transmission pads is mounted on the two lower sub-load beams 4. The positions of the two first force transmission pads need to be as close as possible to or directly placed in the middle position of two adjacent hull rib positions 5 supporting the two lower sub-load beams 4, as shown in FIG. Figure 2 As shown, the distance between the two ends marked with b1 and b2 and the distance between the two ends marked with c1 and c2 make the values ​​of b1 / b2 and c1 / c2 as close to 1 as possible, so that the cargo column foot force on each hull rib position can be uniform. In addition to the illustrated placement method of this embodiment, the transport tooling can adjust the position of the lower sub-load beam 4 according to the different hull rib position distances of different hull structures 1, thereby adjusting the position of the first force transmission pad to achieve uniform load transmission to each hull rib position 5 of the hull structure 1.

[0025] In this embodiment, a second force transmission pad 6 is further provided at the top of the upper sub-load beam 4, and the second force transmission pad 6 is connected to the cargo column foot 100. The second force transmission pad 6 is placed in the middle position of the two first force transmission pads 3. Specifically, in addition to setting the first force transmission pad 3 at the bottom of the upper sub-load beam 2, a second force transmission pad 6 can also be set at the top of the upper sub-load beam 2, and the second force transmission pad 6 is connected to the cargo column foot 100, for receiving the load transmitted by the cargo column foot 100. The position of the second force transmission pad 6 can be set in the middle position of the two first force transmission pads 3 to satisfy that the distance from the second force transmission pad 6 to the two ends of the upper sub-load beam 2 is equal or close, such as Figure 2 The distances between the two ends marked with a1 and a2 shown make the value of a1 / a2 close to 1, so that the column foot force of the cargo column foot 100 can be effectively and evenly distributed to the upper load-bearing beam 2.

[0026] In this embodiment, the transport tooling includes an upper sub-beam 2 and two lower sub-beams 4 (such as Figure 2As shown in the figure, the upper sub-beam 2 has a stiffness greater than that of the two lower sub-beams 4, and the two lower sub-beams 4 are fixed to the ship deck through ribs. Specifically, the upper sub-beam 2 is used to bear the column foot force load transmitted by the cargo column foot 100, and the two lower sub-beams 4 are respectively used to receive the force transmitted by the corresponding first force transmission pads. Compared with the force transmitted by the first force transmission pads, the column foot forces are relatively large, so when designing the upper sub-beam 2, it is necessary to construct the upper sub-beam 2 with steel materials with greater stiffness, and the stiffness requirements for the two lower sub-beams 4 are relatively small. The upper sub-beam 2 and the two lower sub-beams 4 can be box-type or I-beam-type, without specific limitation.

[0027] In this embodiment, the first force transmission pad 3 and the second force transmission pad 6 are both Q355NB steel plates. Specifically, the first force transmission pad 3 is used to be welded at the bottom of the upper sub-beam 2 to receive the column foot force transmitted by the upper sub-beam 2, and then transmitted to the lower sub-beam 2. The second force transmission pad 6 is placed on the top of the upper sub-beam 2 to receive the load transmitted by the cargo column foot 100. The first force transmission pad 3 and the second force transmission pad 6 both play a role in load transmission; Q355NB steel plate is a high-strength low-alloy with excellent mechanical properties and corrosion resistance. In this embodiment, the technical effect of this solution can be well achieved.

[0028] In this embodiment, a transport tool for overload is provided, which distributes the force of the cargo column to multiple ribs of the hull by setting up upper and lower load-sharing beams, thereby reducing the situation where the local load of the hull is too large; by setting a force-transmitting pad between the upper and lower load-sharing beams and adjusting the position of the force-transmitting pad, each rib of the hull can be evenly stressed. The transport tool of the utility model has a simple structure and is convenient for on-site operations.

[0029] The working principle of the utility model is: determine the welding position of the two first force transfer pads 3 at the bottom of the upper sub-loading beam 2 according to the position of the cargo column foot 100, then determine the middle position of two adjacent hull rib positions 5 according to the hull structure 1 drawing, determine the position of the combined structure of the upper sub-loading beam 2 and the first force transfer pads, and then determine the position of the two lower sub-loading beams 4 on the ship deck according to the position of the combined structure, and fix them with rib plates. By moving the position of the first force transfer pad, both ends of the upper sub-loading beam 2 and the two lower sub-loading beams 4 can be evenly stressed, so that each hull rib position 5 of the hull structure 1 is evenly stressed, solving the problem of large local loads.

[0030] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
