[ detailed description ] embodiments

The invention will be further described with reference to the following examples and with reference to the accompanying drawings.

Example 1

The embodiment realizes a marine B-type low-temperature liquid cargo tank supporting system adapting to multidirectional temperature strain.

According to the marine B-type low-temperature liquid cargo tank supporting system adapting to multidirectional temperature strain, the supporting arrangement and the specific structure of a B-tank (B-type low-temperature liquid cargo tank) are optimally designed by combining the actual operation condition of a ship body, so that the safe and reliable operation of the B-tank is ensured. The B-tank support can be divided into a vertical support, an anti-rolling support, an anti-pitching support and an anti-floating support according to functions. Among them, vertical support, anti-pitch support, and anti-roll support are important and difficult points.

The marine B-type low-temperature liquid cargo tank supporting system adapting to multidirectional temperature strain has similar structural forms of anti-rolling support and anti-pitching support, and is different in mounting direction; the pitching refers to the shaking of the B-type low-temperature cargo tank in the advancing direction of the ship body, and the rolling refers to the shaking of the B-type low-temperature cargo tank in the vertical direction of the ship body. FIG. 1 is a structure diagram of a marine B-type low-temperature liquid cargo tank supporting system anti-rolling support adapting to multi-direction temperature strain. As shown in fig. 1, the anti-rolling support structure of the B-type low-temperature cargo tank support system for a ship, which is adapted to multi-directional temperature strain, can be simply divided into an anti-rolling upper support welded to a tank body, an anti-rolling lower support welded to a ship body, and pressure-bearing wood between the anti-rolling upper support and the anti-rolling lower support, wherein the pressure-bearing wood is adhered to the upper support through epoxy resin, and the arrangement direction of the pressure-bearing wood is the vertical direction of the ship body; according to the structure, the ship body can prevent the transverse movement of the tank body during the operation process, but does not influence the longitudinal movement of the tank body.

Similarly, the anti-pitching supporting structure of the marine B-type low-temperature liquid cargo tank supporting system adapting to the multi-direction temperature strain can be simply divided into an anti-pitching upper support welded on the tank body, an anti-pitching lower support welded on the ship body and pressure-bearing wood between the anti-pitching upper support and the anti-pitching lower support, wherein the pressure-bearing wood is adhered to the upper support through epoxy resin, and the arrangement direction of the pressure-bearing wood is the advancing direction of the ship body; according to the structure, the longitudinal movement of the tank body can be prevented during the operation of the ship body, but the transverse movement of the tank body is not influenced. In the marine B-type low-temperature cargo tank supporting system adapted to multidirectional temperature strains, each support has a certain degree of freedom in the other 2 directions while bearing a load in the 1 direction, and can adapt to the temperature strains of the tank body in the 2 directions caused by temperature changes.

The anti-rolling upper support saddle and the anti-rolling lower support saddle are similar, so that the anti-rolling lower support saddle is briefly described. As can be seen from figure 1, the support is mainly formed by welding metal plates, and a certain gap is reserved between the anti-rolling support and the bottom of the pressure-bearing wood. Different thicknesses are adopted according to the action of the metal plate, so that the design is optimized. The part number 18 (1 piece for each left and right, 2 pieces in total) is in direct contact with the pressure-bearing wood to transmit rolling force, so that relative rolling motion between the tank body and the ship body is prevented, a reasonable contact area is calculated according to the allowable strength of the pressure-bearing wood, and the size of the plate is determined. Part number 14 is a transverse large toggle plate, and part number 15 is a longitudinal large toggle plate; part numbers 11-13 are reinforcing rib plate structures, and are tailor welded on

part numbers

14 and 15; the part numbers 11 to 15 are all arranged in bilateral symmetry. Part number 17 is the horizontal reinforcing crescent plate. The parts number 18-111 together constitute an assembly which is arranged in bilateral symmetry. Part number 14 mainly bears and transmits the tank body rolling acting force, a whole plate is adopted and is completely welded with the ship body, and part numbers 11-13, 15 and 17 are used as reinforcing structures, so that the strength of part number 14 is guaranteed. Meanwhile, the two sides of the part number 14 are in smooth transition, so that the fatigue damage resistance is also improved to a certain extent. For larger tank loads, the number of part numbers 14 can be increased in the longitudinal direction to meet the requirements. In order to ensure the installation requirement, the component A consisting of the

parts

18, 19, 110 and 111 is welded after the tank body is installed in place, so that the installation feasibility is ensured.

FIG. 2 is a vertical support structure diagram of a marine B-type low-temperature liquid cargo tank support system adapting to multidirectional temperature strain. As shown in fig. 2, the B-type low-temperature cargo tank support system for ships, which is adapted to multi-directional temperature strain, for vertical support, is also composed of an upper support, a lower support and a middle pressure-bearing wood, wherein the pressure-bearing wood (part number 25) is adhered to an upper support panel (part number 24) through epoxy resin, the lower part of the pressure-bearing wood is in direct contact with a lower support panel (part number 27), and the upper support and the lower support are formed by welding metal plates. The vertical support mainly bears the pressure of the tank body and does not restrict the transverse movement and the longitudinal movement of the tank body. The

part numbers

21 and 23, and 26 and 28 are respectively distributed in a cross shape, so that the stress in the vertical direction is well ensured. The size of the part number 24 is determined according to the allowable strength of the bearing wood, and the part number 22 (arranged in bilateral symmetry and totally 2) mainly plays a role in reinforcing the part number 21.

In the practical use process, the B-type low-temperature liquid cargo tank bears different loads such as internal pressure, sloshing, hull deformation, low temperature and the like, wherein the low-temperature stress is the heavier one. The whole tank body is subjected to thermal shrinkage deformation due to low temperature, and the tank body is damaged due to unreasonable support distribution.

FIG. 3 is a bottom support layout diagram of a tank body of a B-type low-temperature liquid cargo tank support system for a ship, which is adaptive to multidirectional temperature strain. As shown in fig. 3, in the supporting system of the marine B-type low-temperature cargo tank adapted to multidirectional temperature strain, a novel supporting structure arrangement is designed in combination with thermal contraction deformation of a tank body; in the actual use process, the number of the supports is not limited, but the overall idea is not changed. Because the whole tank body bears the low temperature of-163 ℃, the whole tank body shrinks towards the gravity center of the tank body, and 3 anti-pitching supports are arranged at the C.L.1 position of the central line, so that the tank body is prevented from longitudinally moving, and meanwhile, the transverse thermal shrinkage of the tank body is not restrained. 4 anti-rolling supports are arranged at the position of a longitudinal center line C.L.2 of the tank body, so that the tank body is prevented from moving transversely, but the longitudinal shrinkage of the tank body is restrained. The vertical supports are arranged around the central line, and only bear vertical force, so that transverse and longitudinal heat shrinkage is not restrained, and the whole arrangement not only ensures effective support of the tank body, but also ensures effective heat shrinkage of the tank body.

Fig. 4 is a schematic diagram of an implementation of a marine type-B cryogenic liquid cargo tank support system which accommodates multidirectional temperature strains. As shown in fig. 4, the B-type low-temperature cargo tank supporting system for a ship, which is adapted to multi-directional temperature strain, is the same as the embodiment because the anti-pitching support and the anti-rolling support are similar in structure, and therefore, the anti-rolling support is taken as an example for explanation. The vertical support and the anti-rolling support are respectively composed of an upper support welded on the tank body, a lower support welded on the ship body and a middle pressure-bearing wood. Before assembling, the upper support and the lower support are required to meet the design requirements, meanwhile, the bearing wood is respectively pasted on the vertical support and the anti-rolling/pitching upper support through epoxy resin, the thickness of the epoxy resin is generally 8-12mm, and after the upper support and the lower support are firmly assembled. Because the tank body is large, various errors are accumulated, the anti-longitudinal/rolling support is difficult to install, and in order to meet the installation guarantee requirement, the part numbers 18, 19, 10 and 11 need to be installed later. No matter the anti-sway supports or the vertical supports, the bearing wood should be guaranteed to be tightly attached to the contact surface of the support, and the bearing wood is prevented from being damaged due to uneven stress. A little clearance is left with the undersetting in anti-sway support pressure-bearing wood bottom to guarantee that the jar body is used on vertical support. Therefore, before the vertical support is installed, the flatness of the vertical support pressure-bearing wood support plate is guaranteed to be important, and the tolerance requirement of the vertical support pressure-bearing wood support plate needs to be reasonably controlled during design. The support of jar body is arranged conveniently, should fully consider jar body thermal contraction's influence, based on vertical support and the effect of anti-sway support, rational arrangement avoids because the support is arranged unreasonablely, leads to jar body thermal contraction, supports and produces the destruction to jar body.

In the embodiment, the vertical support 1 and the anti-rolling support structure are improved on the basis of the embodiment 1, and the anti-rolling support 2 and the anti-pitching support 3 are collectively called anti-rolling supports.

FIG. 5 is a structural diagram of an improved anti-rolling support structure of a B-type low-temperature liquid cargo tank support system for a ship, which is adaptive to multidirectional temperature strain. As shown in fig. 5, the B-type low-temperature cargo tank supporting system for the ship, which is suitable for multi-directional temperature strain, is modified by adding three components to the anti-rolling support. Wherein, part 31 is a wood in bulk, and this wood piece is in bulk again after jar body integral hoisting to the hull, pastes on leaning on the support of hull part through epoxy, all has bearing structure in two directions, does not need auxiliary device during the installation, can effectively solidify under the support of support, and epoxy solidification back performance is high, and the excellence is as follows: 1) The requirement on the construction precision can be reduced, namely, the supporting seat for connecting the hull part can be allowed to deform greatly, and the final use is not influenced; 2) The requirement on the overall hoisting precision is reduced, and by adopting the structural form, the part 1 can be made to have a larger width, so that the gap between the middle wood and the support of the hull part can be increased during hoisting, and the thickness of the wood can be adjusted according to the final gap; 3) The bulk parts 31 are adopted, so that the metal parts are prevented from being bulk after being hoisted, and the condition that the metal parts are subjected to flame welding in a narrow space is avoided. The element 32 is a toggle plate which is effective to reduce the stress on the wood toe end of the element 31. The component 33 is a water flowing hole, and can effectively lead out leakage liquid in the upper closed space.

Fig. 6 is a structural view of an improved vertical support of a B-type low-temperature liquid cargo tank support system for ships, which is adaptive to multi-directional temperature strain. As shown in figure 6, the B-type low-temperature liquid cargo tank supporting system for the ship, which is suitable for multi-directional temperature strain, has two changes in the vertical supporting structure. The first change is as follows: the part 41 is a toggle plate which is propped against the tank body, the area of the vertical force which is upwards applied to the hull can be increased by the toggle plate, the bearing capacity of the support structure can be effectively improved, the support structure is particularly suitable for the low-strength support structure of aluminum alloy, meanwhile, the space of the part which is not connected with the tank body can provide a welding space for the nearby communicated toggle plate, the welding quality and the weldability of the nearby toggle plate are ensured, the application range of the vertical support can be effectively improved by the combination of the toggle plates with different types at two weeks, and the support can be used from low load to high load. And (2) changing: the pressure-bearing wood is divided into two parts, namely an upper half pressure-bearing wood 43 and a lower half pressure-bearing wood 42, and the advantages are as follows: 1. the vertically supported bearing wood can be brought on the tank body by the upper half bearing wood 43, and the lower half bearing wood 42 is placed on the ship body, so that the hoisting weight can be reduced, and the hoisting requirement can be easily met; 2. the upper part and the lower part can be respectively used for adjusting the flatness among a plurality of bearing woods of the tank body, so that the leveling is effective, the adjustment of the height of a metal surface is avoided, the leveling effect by cutting or polishing the plane of the bearing wood is better, and the operation is easier; 3. the width of the wood of the lower half pressure-bearing wood 42 is large, so that the wood of the upper half pressure-bearing wood 42 can slide on the upper surface, and the expansion with heat and the contraction with cold of the tank body are effectively adjusted.
