As shown in fig. 2:
(1) in this embodiment, the multi-directional limiting and supporting device 3 is divided into an upper part, a middle part and a lower part, and comprises an upper laminated wood 301, a lower laminated wood 302 and a supporting cylinder 303; the upper laminated wood 301 is fixedly connected with the bottom surface of the independent liquid tank 2, and the lower laminated wood 302 is fixedly connected with the ship body 1; the axis of the supporting cylinder 303 is horizontally arranged, and the bottom surface of the laminated wood 301 at the upper end and the top surface of the laminated wood 302 at the lower end are both provided with arc- shaped grooves 318 and 319 which are matched with the arc-shaped cylindrical surface of the supporting cylinder 303.

(3) In this embodiment, the middle portion of the multi-directional spacing support 3 comprises a support cylinder 303, an upper arc plate 304 and a lower arc plate 305. Wherein the upper arc-shaped plate 304 is covered on the bottom surface of the upper laminated wood 301, the lower arc-shaped plate 305 is covered on the top surface of the lower laminated wood 302, and the upper and lower cylindrical surfaces of the supporting cylinder 303 are respectively contacted with the upper arc-shaped plate 304 and the lower arc-shaped plate 305. Preferably, the support cylinder 303 is a hollow steel pipe, which not only has good strength, but also can save materials and reduce weight. Preferably, the upper arc-shaped plate 304 and the lower arc-shaped plate 305 are made of stainless steel plates or special low-temperature steel plates, and the upper arc-shaped plate 304 and the lower arc-shaped plate 305 block the support cylinder 303 from directly contacting the upper laminated wood 301 and the lower laminated wood 302, so as to protect the laminated wood, because when the support cylinder 303 is subjected to loads in various directions and moves, if the support cylinder is directly contacted with the laminated wood, frequent relative friction movement may damage the laminated wood with weaker strength.
(4) In this embodiment, an epoxy mastic 315 is disposed between the upper arc-shaped plate 304 and the lower arc-shaped plate 305, and the epoxy mastic 315 mainly functions as: the flatness is adjusted by setting epoxy mastic 315 with different thicknesses according to actual conditions by considering possible errors in actual construction and assembly, and the thickness is generally not more than 80 mm.
(5) In this embodiment, preferably, a plurality of upper end baffles 307 are fixed on the independent liquid tank 2, the upper laminated wood 301 is limited between the upper end baffles 307, and the upper end baffles 307 mainly function as: on the one hand, the movement of the upper laminated wood 301 in the horizontal plane direction is effectively limited; on the other hand, the tank load of the water level can be effectively carried. Preferably, an upper end toggle plate 306 is further fixed on the independent liquid tank 2, and the upper end toggle plate 306 is vertically connected with the outer side surface of the upper end baffle 307 and the surface of the independent liquid tank 2; a plurality of lower end baffles 309 are fixed on the hull 1, and the lower laminated wood 302 is limited between the lower end baffles 309. A lower end bracket plate 308 is fixed on the hull 1, and the lower end bracket plate 308 is vertically connected with the outer side surface of the lower end baffle 309 and the surface of the hull 1. Preferably, an upper top plate 316 and a lower top plate 317 are further arranged between the upper end toggle plate 306 and the lower end toggle plate 308, and the upper top plate 316 is vertically connected with the outer side surface of the upper end baffle 307 and the upper end toggle plate 306; the lower top plate 317 is vertically connected to the outer side surface of the lower end baffle 309 and the lower end toggle plate 308.
(6) Since the independent liquid tank 2 is generally formed by butt-welding a plurality of steel plates, and a plurality of butt-welding seams 312 exist on the surface of the independent liquid tank, in this embodiment, it is preferable that flow guide grooves 311 are provided on the top surface of the upper laminated wood 301 at positions corresponding to the butt-welding seams 312 on the independent liquid tank 2, and the number of the flow guide grooves is the same as the number of the butt-welding seams 312 within the coverage range of the upper laminated wood 301. The flow guiding groove 311 is located below the butt weld 312, and has a width generally not less than 50mm and a height generally not less than 12 mm.

(7) In this embodiment, the separate tank 2 and the upper laminated wood 301 are bonded by strong glue 313. The function of the glue 313 is as follows: the independent liquid tank 2 and the laminated wood 301 at the upper end are strongly bonded, according to a conventional construction method, after the whole independent liquid tank 2 is constructed and formed, the whole independent liquid tank 2 is hoisted into a cabin of the ship body 1, and the laminated wood 301 at the upper end is bonded to the independent liquid tank 2 through the strong glue 313 and hoisted along with the tank, so that the assembly is convenient.
(8) In this embodiment, the lower end baffle 309 is supported by a combined toggle plate of a lower toggle plate 308 and a lower triangular toggle plate 310, and the lower triangular toggle plate 310 is vertically connected between the top surface of the lower top plate 317 and the outer side surface of the lower end baffle 309.

(9) In this embodiment, preferably, a hydraulic cylinder 314 is further disposed between the upper top plate 316 and the lower top plate 317. The main functions of the hydraulic cylinder 314 are: when the independent liquid tank 2 is hoisted to the ship body 1, the relative positions of the upper part, the middle part and the lower part of the individual multidirectional limiting and supporting device 3 need to be slightly adjusted due to construction and assembly errors. After the independent liquid tank 2 is hoisted, considering that the weight of the independent liquid tank 2 is large, the independent liquid tank 2 cannot be jacked manually, the hydraulic cylinder 314 is needed to be used for jacking and displacing the whole independent liquid tank 2 vertically, and then epoxy cement 315 is injected between the upward arc-shaped plate 304 and the lower arc-shaped plate 305 to adjust the height and the flatness of the multidirectional limiting and supporting device 3.
As shown in fig. 3:
(1) in the liquid cargo ship of the invention, a plurality of multi-directional limiting and supporting devices 3 are arranged according to the weight of the independent liquid tanks 2 and the arrangement characteristics of the strong components, so that the safety requirement can be met, and the detailed description is shown in figure 3.
(2) In this embodiment, the multi-directional position limiting support device 3 is arranged in a scattered form, is generally symmetrical along the port and starboard sides in the ship, and can be flexibly arranged, but the upper end toggle plate 306 and the lower end toggle plate 308 are required to be in the same plane (aligned) with the strong components of the independent liquid tank 2 and the ship body 1; ensuring that the load is transferred efficiently.
(3) Considering that the supporting force distribution of the supporting points of the independent liquid tank 2 is uneven, each component of the multidirectional limiting and supporting device 3 can be divided into a plurality of gears or types according to the size of the supporting force, and the structural sizes of different types are different, so that the rationality and the economy of structural design are ensured. In general, the multi-directional position-limiting support devices 3 at the positions in the ship are transversely arranged, so that the transverse load of the liquid tank can be effectively borne, and in addition, the multi-directional position-limiting support devices 3 are longitudinally arranged for bearing the longitudinal load of the liquid tank, and the multi-directional position-limiting support devices 3 are transversely arranged for bearing the transverse load of the liquid tank.
In fig. 3, the 2 nd row is arranged longitudinally, the 3 rd row is arranged transversely, which is only an example, and in practical cases, the arrangement may be partially different.
In summary, the cargo tanker with the multi-directional limiting and supporting device can effectively reduce damage to the ship body and the liquid tank caused by the self-gravity of the cargo tank and external loads from multiple directions during transportation, and improve the safety of liquid cargo transportation. Therefore, the invention effectively overcomes some practical problems in the prior art and has high utilization value and use significance.
