Detailed Description
The present invention will be described in detail and specifically with reference to specific embodiments so as to provide a better understanding of the present invention, but the following embodiments do not limit the scope of the present invention.
The utility model provides a docking block arrangement structure of large-scale ocean oil and gas equipment carries out individualized layout based on rigidity distribution theory, mainly show to encrypt along the great board of structural rigidity and arrange, fully consider structural rigidity's in succession on this basis, prevent that structural rigidity from concentrating the boats and ships load that leads to and share the inequality, thereby cause the counter-force to concentrate on some buttress, simultaneously because the docking block arranges according to rigidity distribution theory, the counter-force is more reasonable along the distribution of docking block, also solved the problem of hardly arranging the docking block under the effective area.
The utility model discloses in, large-scale ocean oil gas equipment divide into the prelude, middle part and afterbody, and this docking block arrangement structure is based on arranging the method to the docking block including arranging the position and arranging the direction to and the size of docking block, and the rationality that the theoretical analysis of rigidity was arranged the docking block is explained in detail in four aspects of the material of docking block.
As shown in fig. 2, the utility model provides a docking block arrangement structure of large-scale ocean oil and gas equipment, it arranges in the dock in order to support the hull, comprises a plurality of docking blocks 2, at least part docking block 2 along the length direction one by one transversely arrange in horizontal bulkhead 1's below. In the head-tail area of large-scale ocean oil and gas equipment, the docking blocks close to the outermost side of the transverse bulkhead 1 bear the weight of a head-tail outward floating structure, so that the arrangement number of the transverse docking blocks 2 can influence the magnitude of the support reaction force of the docking blocks 2, in the process of arranging the docking blocks 2 in the transverse direction, in order to arrange more support blocks 2 at the positions of the transverse bulkhead 1, the arrangement direction of the docking blocks below the position of the transverse bulkhead 1 is longitudinally arranged along the ship body, the arrangement number of the docking blocks 2 can be greatly increased, and the support reaction force of most of the support blocks is effectively dispersed.
As a preferred embodiment, after the transverse buttresses shown in fig. 2 are arranged, in order to avoid a phenomenon that a supporting reaction force of a local dock block is too concentrated due to too large structural rigidity at a position where the transverse bulkhead 1 and the bottom longitudinal quilting or solid rib plate 3 are staggered, the dock block 2 is divided into two parts, and one part of the dock block 2 is transversely arranged below the transverse bulkhead 1 one by one along the length direction of the transverse bulkhead 1; the other part of the docking blocks 2 are divided into a plurality of docking block groups which are arranged side by side, and the docking block groups are longitudinally arranged below the intersection of the transverse bulkhead 1 and the bottom longitudinal quilting or solid rib plate 3. Specifically, a plurality of docking block groups composed of transverse docking blocks 2 are arranged at positions with high structural rigidity, such as the positions where the transverse bulkhead 1 and the bottom longitudinal quilted or solid rib plate 3 are staggered, or the positions where the transverse bulkhead 2 and the bottom longitudinal quilted or solid rib plate 3 are staggered, along the longitudinal direction.
In this embodiment, as shown in fig. 3, the length of the docking block group is 1-3 times of the length of the docking block 2 along the length direction of the bottom longitudinal quilting or solid rib plate 3. Preferably, the length of the docking block group is 2 times of the length of the docking block. The length of the docking block group is similar to that of the docking block group in the longitudinal arrangement direction, and the docking block group in the transverse and longitudinal arrangement directions is similar in size, so that the rigidity of the docking block is ensured to be continuous, but the arrangement direction of the docking block is changed, so that the phenomenon of local structure rigidity concentration is avoided, and the phenomenon of support reaction force concentration of the docking block is effectively avoided.
In this embodiment, as shown in fig. 3, a distance between two adjacent docking blocks 2 in the docking block group is smaller than a distance between two adjacent docking blocks 2 which are transversely arranged. Each docking block group consists of at least two docking blocks 2; at least three docking blocks 2 are arranged between two adjacent docking block groups, and specifically, as shown in fig. 3, each docking block group is composed of three docking blocks 2; and four docking blocks 2 are arranged between two adjacent docking block groups.
As a preferred embodiment, the number of the docking blocks 2 below the bow and the stern of the transverse bulkhead 1 corresponding to the hull is smaller than the number of the docking blocks 2 below the rest of the transverse bulkhead 1. At the bilge positions at the head and the tail of the hull, a plurality of docking blocks with generally large support reaction forces exist, at this time, due to the fact that the structural rigidity of the docking block is large and the weight of the hull is heavy, the weight of the whole outboard structure and the weight of a part of the outboard structure at the head and the tail are transmitted to the docking block through the transverse bulkhead and the outboard plate, the support reaction force of the docking block is too large, at this time, the rigidity provided by the docking block should be reduced, the support reaction forces are effectively dispersed to other support blocks, and therefore the number of the docking blocks or the size of the docking block should be properly reduced.
As a preferred embodiment, the size of the docking blocks 2 below the ship center line of the transverse bulkhead 1 is smaller than the size of the docking blocks 2 below the rest area of the transverse bulkhead 1. At the middle position of the hull, due to the fact that a large opening exists near the center line of the ship, the upper and lower continuous structures are few, equipment is few, the weight of the empty ship at the part is light, therefore, the wooden pier can be equipped to reduce the demand of the iron pier, the buttress located at the side bilge bears large ship load, at the moment, the longitudinal encryption buttress is transversely arranged, the support reaction force of the buttress can be effectively improved, and the requirement is met.
As a preferred embodiment, as shown in fig. 4, a magnetic induction device 5 is installed on at least one of the docking blocks 2 with a large support reaction force; and a magnetic induction appendage 4 matched with the magnetic induction equipment 5 is welded on the ship body corresponding to the docking block 2. The magnetic induction appendage 4 and the magnetic induction equipment 5 are respectively arranged on the hull below the intersection of the transverse bulkhead 1 and the bottom longitudinal quilting or solid rib plate 3 and the docking block 2. The magnetic induction coil is arranged on the large docking block, the sinking of the large docking block is properly adjusted through the repulsive force, so that the docking block support reaction load at the position is adjusted, and the effect of evenly sharing the support reaction force borne by the docking block in the area is achieved.
Specifically, as shown in fig. 5, the magnetic induction appendage and the magnetic induction device realize the docking block support reaction load by a principle similar to that of a magnetic levitation railway, and are provided with two opposite winding coils 6, which are indicated as two solid blocks arranged above and below in the drawing, and two generator sets 7 respectively connected with the two winding coils, wherein the current winding directions of the generator sets 7 can ensure that the two winding coils 6 are in a repulsive state. The magnetic induction body 4 is a device similar to bilge keels of ships, and the magnetic induction body 4 is used for being arranged on a docking block 2 arrangement line and is used for evenly sharing counter force of the docking block 2.
The principle that the ship weight is uniformly shared by the magnetic induction appendage and the magnetic induction equipment is adopted in the embodiment as follows: due to the fact that structural rigidity of the ship is not uniformly distributed, support reaction force borne by the docking block 2 is very non-uniform, the docking block in some places may be less than 50 blocks, and a certain docking block nearby the docking block bears a large part of weight, even more than 300 tons, and far exceeds the bearing range of a common docking block. The embodiment is based on the electromagnetic levitation principle, the magnetic induction appendage 4 and the magnetic induction equipment 5 are respectively controlled to adjust the ship sinking amount of the dock block 2 at the heavy position by controlling the current of the streaming coil, so that the support reaction force of the dock block 2 at the heavy position can be uniformly distributed on the dock block 2 with smaller support reaction force.
As a preferred embodiment, the docking blocks 2 are made of iron and/or wood. The horizontal bulkhead 1 corresponds to a plurality of docking blocks 2 below the ship center line of the ship body and are made of wood, the middle position of the ship body is provided with a large opening near the ship center line, the upper and lower continuous structures are fewer, equipment is fewer, and the empty ship of the part is lighter in weight, so that the wood blocks can be arranged to reduce the demand of the iron blocks.
The utility model provides a docking block arrangement structure makes the docking block of arranging this board of perpendicular to under the great board of hull structure rigidity to arrange the docking block that is on a parallel with this board at this board and the great vertical additional strengthening position of rigidity, to the nonlinear characteristics that docking block counter-force distribution appears, through individualized docking block of arranging, make the counter-force of propping up of docking block satisfy the engineering operation requirement, realize the effective safe support of large-scale ocean oil gas equipment.
