Description

Technical Field

[0001] The invention relates to the technical field of ship supports, in particular to a ship laminated wood support and a supporting method. Background Art

[0002] In the field of marine engineering and shipbuilding, the design and manufacture of deck tanks has always been a technical problem. Especially in special ships such as chemical tankers and liquefied gas tankers, the safe, stable and efficient operation of the tanks has a decisive impact on the safety and performance of the entire ship. During the voyage of the ship, the deck tanks will generate significant inertial impact forces due to the sloshing of liquid and the movement of the ship. If these impact forces are not effectively buffered and dispersed, they will directly affect the structural safety of the tanks and the overall stability of the ship.

[0003] Traditional tank bracket designs often only consider the basic functions of supporting and fixing the tank, while ignoring the dynamic impact on the tank during the movement of the ship. This design may perform well when the ship is static or sailing at low speed, but when encountering complex navigation conditions such as wind and waves, sharp turns, or acceleration and deceleration, the tank bracket often cannot effectively buffer and disperse the inertial impact force generated by the sloshing of the liquid, resulting in the tank bracket breaking due to stress concentration, the tank falling and being damaged, and even causing safety accidents.

[0004] In addition, with the development of ship technology and the continuous increase in ship size, the capacity and size of deck tanks are also increasing, which makes the inertial impact force generated by the tanks during the movement of the ship more significant. When the traditional tank bracket is subjected to a large pressure on one side, it cannot cooperate with other parts of the bracket to eliminate stress, and the stress is easily concentrated. Therefore, it has gradually failed to meet the requirements of modern ships for tank stability and safety.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-9 The present invention provides a technical solution: comprising a deck 1 and a liquid tank 2, support assemblies 3 are symmetrically arranged on both sides of the liquid tank 2, a buffer assembly 4 is arranged below the support assembly 3, and a laminate 303 is arranged between the support assembly 3 and the buffer assembly 4. The laminate 303 can block the transfer of temperature to prevent the temperature from being transferred to the deck 1 through the support assembly 3 and the buffer assembly 4 when low-temperature liquid is stored in the liquid tank 2, causing the deck 1 to be deformed and damaged due to thermal expansion and contraction.

[0038] The buffer assembly 4 includes a hydraulic tank 401, which is connected to the deck 1 and filled with hydraulic oil 404. A large piston 405 and a small piston 406 are sealed at both ends of the hydraulic tank 401, and the small pistons 406 are fixedly connected to each other. The large piston 405 is rotatably connected to the lower ends of the support assemblies 3 on both sides of the liquid tank 2 respectively. A slide groove adapted to a large push rod 407 and a small push rod 408 is provided in the deck 1. The support assembly 3 is located above the deck 1, and the buffer assembly 4 is located below the deck 1. The top surfaces of the first sleeve 402 and the second sleeve 403 are welded to the bottom surface of the deck 1.

[0039] The other ends of the large push rod 407 and the small push rod 408 are both located above the deck 1. A first sleeve 402 is provided on the side of the top surface of the hydraulic warehouse 401 away from the central axis of the liquid tank 2. The large piston 405 is slidably and sealedly connected to the inner wall of the first sleeve 402. One end of the large push rod 407 is provided on the top surface of the large piston 405. A hole adapted to the large push rod 407 is opened on the top surface of the first sleeve 402. A second sleeve 403 is provided on the side of the top surface of the hydraulic warehouse 401 close to the central axis of the liquid tank 2. The small piston 406 is slidably and sealedly connected to the inner wall of the second sleeve 403. One end of the small push rod 408 is fixedly connected to the top surface of the small piston 406. A hole adapted to the small push rod 408 is opened on the top surface of the second sleeve 403. The other ends of the two small push rods 408 are passed through the corresponding holes and are respectively fixedly connected to the two sides of the connecting plate 409.

[0040] By adopting the above design, when the ship is sailing on the sea and sways with the impact of waves, the liquid tank 2 will also sway due to inertia. When the liquid tank 2 sways toward the left, the welding frame 301 welded on the right side will pull the large piston 405 on that side up.

[0041] According to Pascal's law, when a static liquid in a closed container is subjected to pressure at a certain point, the pressure will be transmitted by the liquid in all directions without changing its magnitude. That is, any point in the liquid will be subjected to equal pressure, and the liquid is incompressible.

[0042] Therefore, when the large piston 405 on the right side rises, the pressure of the hydraulic oil 404 in the right hydraulic chamber 401 will change, and this pressure change will also act on the small piston 406 on the right side, so the small piston 406 will drop accordingly. The small pistons 406 are fixedly connected by a connecting plate 409, so when the small piston 406 on the right side drops, the small piston 406 on the left side will also drop synchronously. When the small piston 406 on the left side drops, the pressure of the hydraulic oil 404 in the left hydraulic chamber 401 will change, and this pressure change will also act on the large piston 405 on the left side, driving the large piston 405 on the left side to rise synchronously.

[0043] As a result, when the liquid tank 2 shakes and generates impact force, the support assembly 3 can move within a certain range, thereby dispersing the impact force among the various components of the support assembly 3 and the buffer assembly 4, thereby sharing the impact force that the welding frame 301 needs to bear, preventing the support assembly 3 from breaking due to stress concentration, causing the liquid tank 2 to fall and be damaged, thereby improving the safety of the present invention.

[0044] The buffer component 4 can also be used to perform reciprocating conversion to generate a reverse force, thereby reducing the sway amplitude of the liquid tank 2. The resistance in the conversion process and the reaction force generated are used to offset the impact force, so that the impact force is quickly consumed, thereby further improving the safety of the device.

[0045] Furthermore, because force is equal to area multiplied by pressure, that is, F=P×A, the force that the small piston 406 needs to withstand and transform is different from that of the large piston 405. During the production process, the area ratio between the large piston 405 and the small piston 406 can be adjusted according to the volume of the liquid tank 2 to be carried and the material used for the buffer component 4, thereby preventing the small piston 406 from being unable to withstand the required transmission force due to its shorter diameter.

[0046] Specifically, the two support assemblies 3 and the two buffer assemblies 4 form a group, and three groups are provided in total, two of which are located at two ends of the liquid tank 2 , and one is located in the middle of the liquid tank 2 .

[0047] By adopting the above design, more support components 3 and buffer components 4 are provided for sharing and converting the impact force generated by the inertia of the liquid tank 2, thereby making the stress more dispersed, further reducing the possibility of fracture of the support component 3 due to stress concentration, and reducing the tensile force that each component of the buffer component 4 needs to withstand during operation, making the operation of the buffer component 4 safer.

[0048] See also Figure 1-8 Further, the support assembly 3 includes a welding frame 301, an upper clamping sleeve 302 is welded on the bottom surface of the welding frame 301, an upper clamping block 3031 is integrally formed at the upper end of the laminate 303, and the laminate 303 is interference connected in the upper clamping sleeve 302 through the upper clamping block 3031, and the support assembly 3 also includes a lower clamping sleeve 304, a lower clamping block 3032 is integrally formed at the lower end of the laminate 303, and the upper clamping block 3031 is interference connected with the lower clamping sleeve 304 through the lower clamping block 3032, and a ball sleeve 305 is welded on the bottom surface of the lower clamping sleeve 304, a connecting ball 306 is connected to the gap in the ball sleeve 305, and the other end of the large push rod 407 is welded to the connecting ball 306, and the other end of the large push rod 407 is rotatably connected to the ball sleeve 305 through the connecting ball 306.

[0049] By adopting the above design, the support component 3 can be rotatably connected to the large piston 405, so that when the liquid tank 2 is subjected to various reverse impact forces due to the start and stop of the ship or the impact of waves, the large piston 405 in the opposite direction can be pulled up respectively, so that the device can not only buffer the lateral impact force generated by the inertia of the buffer tank 2, but also the impact forces generated in various directions will be dispersed through the movement of the support component 3, and eliminated through the conversion and offset of the buffer component 4, thereby making the operation of the device more stable.

[0050] In addition, reference Figure 1-5 The inner side of the welding frame 301 is arc-shaped and the outer side is at a right angle. The arc is adapted to the side wall of the liquid tank 2. The welding frame 301 is hollow and a plurality of reinforcing plates 3011 are arranged in the welding frame 301.

[0051] By adopting the above design, the welding frame 301 is reduced in weight for easy transportation, and has a rigid structural support inside so as not to be easily broken or deformed.

[0052] A method for supporting a laminated wood support for a ship: a slide groove is opened on a deck 1, a large push rod 407 and a small push rod 408 are passed through the slide groove, the top surface of the first sliding sleeve 402 and the second sliding sleeve 403 are welded to the bottom surface of the deck 1, the top surface of the small push rod 408 is welded to both sides of the bottom surface of the connecting plate 409, and then half of the ball sleeve 305 is clamped on the connecting ball 306, and half of the upper clamping sleeve 302 and the lower clamping sleeve 304 are clamped on the upper clamping block 3031 and the lower clamping block 3032, and then the clamping parts are welded, and the ball sleeve 305 is clamped on the connecting ball 306. The top of the sleeve 305 and the center of the bottom surface of the lower clamping sleeve 304, the top of the upper clamping sleeve 302 and the bottom end of the welding frame 301, the connecting ball 306 and the other end of the large push rod 407 are welded in sequence, and the above operation is repeated 3 times. Then the liquid tank 2 is lifted by the crane, and the middle part of the liquid tank 2 is aligned with the notch of the middle welding frame 301 and lowered until it contacts the welding frame 301. At this time, the crane is paused, and the connection between the welding frame 301 and the liquid tank 2 is welded. The sling can be loosened to complete the installation of the liquid tank 2, the support assembly 3 and the buffer assembly 4.

[0053] When the ship is sailing on the sea and sways with the impact of waves, the liquid tank 2 will also sway due to inertia. When the liquid tank 2 sways toward the left, the welding frame 301 welded on the right side will pull the large piston 405 on that side to rise. According to Pascal's law, when the large piston 405 rises, the small piston 406 will make a corresponding drop, and the drop of the small piston 406 will drive the drop of the other small piston 406, thereby causing the other large piston 405 to rise, generating a supporting force from the left side toward the right side.

[0054] Working principle:

[0055] During installation, according to the size of the liquid tank 2, a corresponding welding frame 301 is produced, and then a laminate 303 of a corresponding size is produced, and the upper sleeve 302, the lower sleeve 304 and half of the ball sleeve 305 are provided. A slide groove is opened on the deck 1, so that the large push rod 407 and the small push rod 408 pass through the slide groove, and the top surface of the first sleeve 402 and the second sleeve 403 are welded to the bottom surface of the deck 1, and the top surface of the small push rod 408 is welded to both sides of the bottom surface of the connecting plate 409, and then half of the ball sleeve 305 is clamped on the connecting ball 306, and the upper sleeve 302 and half of the lower sleeve 304 are clamped on the upper block 303. 1 and the lower clamping block 3032, then weld the clamping parts, and weld the top of the ball sleeve 305 and the center of the bottom surface of the lower clamping sleeve 304, the top of the upper clamping sleeve 302 and the bottom of the welding frame 301, the connecting ball 306 and the other end of the large push rod 407 in sequence, repeat the above operation support assembly 3 times, then lift the liquid tank 2 by the crane, align the middle part of the liquid tank 2 with the notch of the middle welding frame 301 and lower it until it contacts the welding frame 301, then stop the crane, weld the connection between the welding frame 301 and the liquid tank 2, and then release the sling to complete the installation of the liquid tank 2, the support assembly 3 and the buffer assembly 4.

[0056] When the ship is sailing on the sea and sways with the impact of waves, the liquid tank 2 will also sway due to inertia. When the liquid tank 2 sways toward the left, the welding frame 301 welded on the right side will pull the large piston 405 on that side to rise.

[0057] According to Pascal's law, when a static liquid in a closed container is subjected to pressure at a certain point, the pressure will be transmitted by the liquid in all directions without changing its magnitude. That is, any point in the liquid will be subjected to equal pressure, and the liquid is incompressible.

[0058] Therefore, when the large piston 405 on the right side rises, the pressure of the hydraulic oil 404 in the right hydraulic chamber 401 will change, and this pressure change will also act on the small piston 406 on the right side, so the small piston 406 will drop accordingly. The small pistons 406 are fixedly connected by a connecting plate 409, so when the small piston 406 on the right side drops, the small piston 406 on the left side will also drop synchronously. When the small piston 406 on the left side drops, the pressure of the hydraulic oil 404 in the left hydraulic chamber 401 will change, and this pressure change will also act on the large piston 405 on the left side, driving the large piston 405 on the left side to rise synchronously.

[0059] As a result, when the liquid tank 2 shakes and generates impact force, the support assembly 3 can move within a certain range, thereby dispersing the impact force among the various components of the support assembly 3 and the buffer assembly 4, thereby sharing the impact force that the welding frame 301 needs to bear, preventing the support assembly 3 from breaking due to stress concentration, causing the liquid tank 2 to fall and be damaged, thereby improving the safety of the present invention.

[0060] Moreover, the buffer component 4 can also be used to perform reciprocating conversion to generate a reverse force, thereby reducing the sway amplitude of the liquid tank 2. The resistance in the conversion process and the reaction force generated are offset from the impact force, so that the impact force is quickly consumed, thereby further improving the safety of the device.
