Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention cannot be limited by this.
[0039] Such as Figure 1 to Figure 2 As shown, the present invention provides a support system for an IMO A-type standard liquid cargo tank of a liquefied gas carrier, which is used to support the liquid tank in the liquid cargo tank, including anti-pitch support 1, anti-roll support 2, 5 , Anti-floating support 3, sliding support 4. Among them, the support that prevents the tank from pitching and restricts the longitudinal displacement of the tank and the double hull is called the anti-pitch support 1, which prevents the tank from rolling and tilts, and limits the lateral displacement of the tank and the double hull. The support for displacement is called anti-rolling support 2 and 5, the support for preventing the tank body from floating in the empty cabin due to th...

The invention discloses a support system for an A-type standard liquid cargo tank of an ultra-low-temperature liquefied gas tanker IMO. The support system comprises an anti-pitching support, an anti-rolling support, a floating check support and a sliding support, the anti-pitching support is mounted on the longitudinal center line of the bottom of a tank body, bearing blocks are fixed by the aid of baffles and key plate brackets, an upper metal structure part is welded with the tank body, the bearing blocks and the metal structure part longitudinally slide through stainless steel sheets, the anti-rolling support is mounted on the transverse center line of the tanker bottom and tanker top and can transversely slide, the floating check support is mounted at the tanker top, two rows of key plates fix the bearing blocks through epoxy resin, gaps are reserved among upper bearing blocks and lower bearing blocks, the sliding seat is mounted at the tanker bottom, and the key plate brackets peripherally fix the bearing blocks through the epoxy resin. According to the support system, the liquefied gas tanker can be effectively supported, low-temperature influence on a ship structure is effectively blocked, the liquefied gas tanker is allowed to deform and shrink at the low temperature, the liquefied gas tanker and the ship structure relatively slide, and support stress is decreased as far as possible.
Description
technical field [0001] The invention relates to a support for ships, in particular to a support system for an IMO type A standard liquid cargo tank of a liquefied gas carrier. Background technique [0002] Liquefied natural gas (LNG), as a new type of energy with high calorific value, clean and pollution-free, has the advantages of clean combustion and low pollution. Now it has been widely used in industrial production in many developed countries and has become the main energy source in the world. During the operation of the liquefied gas carrier, the liquid cargo in the independent tank is at minus 163°C, and there is heat exchange between the outside air and the surrounding seawater. A certain number of supports need to be set between the liquid tank and the hull structure to block the low temperature. and support tanks. Due to the large deformation and shrinkage of the tank body under a large temperature difference, it is necessary to slide relative to the support and th...
