Description

Technical Field

[0001] The invention relates to the field of installation of shipborne B-type cabins, and in particular to a flexible slide rail for non-injury entry and precise installation and positioning of shipborne B-type cabins under swaying conditions at sea. Background Art

[0002] Type B tanks are tank-shaped devices used by liquefied gas carriers to store cryogenic liquefied gas. To install a Type B tank, it is necessary to use lifting equipment to lift the Type B tank and drop it from the hatch of the hull to the saddle arranged on the bottom of the hull.

[0003] When using lifting equipment to install the Type B cabin at sea, if the weather conditions are not good, the Type B cabin will be affected by the wind and waves and will sway constantly. When entering the hull hatch, it is very easy to collide with the hull hatch structure, causing damage to the insulation layer on the surface of the Type B cabin. At the same time, the Type B cabin in a swaying state cannot be accurately positioned in the length and width directions of the ship. In the traditional solution, the hydraulic oil top arranged at the bottom of the Type B cabin can only adjust the height and levelness of the Type B cabin, and cannot adjust the position of the Type B cabin in the length and width directions of the ship. Summary of the invention

[0004] In view of the above problems, the present invention provides a mechanism and a method for the offshore entry and positioning installation of a ship-borne B-type tank, which aims to smoothly realize the position positioning and installation of the B-type tank in the length direction and the width direction of the ship.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a mechanism and method for entering and positioning a ship-borne B-type tank at sea, which first uses a flexible slide rail for non-injury entry and precise installation and positioning of a ship-borne B-type liquid cargo tank under sloshing conditions at sea. The flexible slide rail includes: a two-way guide wheel structure, a slide rail, and a slide rail base. The two-way guide wheel structure frame is a steel structure, the guide wheel is made of rubber, and the two-way guide wheel structure is installed at the bottom of the left and right bulkheads of the B-type tank for sliding along the slide rail. The guide wheel structure is divided into two parts: a main body and a base, and the main body and the base are connected by bolts. The slide rail is a steel structure, and the introduction structure located at the upper part of the slide rail protrudes out of the hull deck in a flared shape, and is connected to the hull deck through a damping and shock-absorbing device. The main part of the slide rail penetrates into the cabin and leans on the slide rail base. The slide rail base is a steel structure and is welded to the left and right bulkheads of the hull. There are three types of slide rail bases: a fixed base, an elastic base, and an adjustable base. The fixed base is located at the hull hatch and is welded to the hull bulkhead and the slide rail. The elastic base is located on the bulkhead of the hull, and its surface is covered with elastic rubber. The adjustment base is located on the bulkhead of the hull, and corresponds to the end of the slide rail in terms of position height. A top screw is provided on it, and the top screw can be rotated to extend or retract;

[0006] The beneficial effects of the present invention are:

[0007] 1. When the B-type cabin contacts the slide rail in a swaying state, the slide rail can absorb and consume the energy generated by the swaying of the B-type cabin through the damping and shock absorbing device, the elastic base and its own elastic deformation, so that the swaying amplitude of the B-type cabin is gradually reduced until it tends to be stable, thus avoiding the rigid collision between the B-type cabin and the hull, and protecting the structure and surface insulation of the B-type cabin;

[0008] 2. Before the B-type cabin falls on the saddle, the position of the end of the slide rail in the length and width directions of the ship is finely adjusted by the top screw, so that the B-type cabin can be accurately introduced into the cabin saddle. The high-precision positioning of the B-type cabin can be completed with the hydraulic oil top.

[0009] 3. After the guide wheel body is installed and positioned in the B-type cabin, it is removed from the guide wheel base. The guide wheel base is permanently retained on the B-type cabin and covered with insulating material, which will not affect the bottom temperature of the B-type cabin.

[0010] 4. The slide rail and the hull are only welded at the fixed base, which is easy to disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be based on different viewpoints and applications without departing from the present invention.

[0022] Various modifications or changes can be made within the spirit of the present invention.

[0023] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be adjusted, and the component layout type may also be more complicated.

[0024] like Figures 1 to 9 As shown, the present invention provides a flexible slide rail for non-damage entry and precise installation and positioning of a ship-borne B-type liquid cargo tank under sloshing conditions at sea.

[0025] The flexible slide rail at least includes a two-way guide wheel structure 4, a slide rail introduction structure 5, a damping and shock absorbing device 6, a slide rail body 7, a fixed base 8, an elastic base 9, and an adjustment base 10.

[0026] The two-way guide wheel structure 4 is arranged at the four corners of the bottom of the left and right bulkheads of the B-type tank 1.

[0027] The two-way guide wheel structure 4 is composed of a main body and a base;

[0028] The main body of the two-way guide wheel structure 4 is provided with a longitudinal guide wheel 12 and a transverse guide wheel 13; the longitudinal guide wheel 12 and the transverse guide wheel 13 are fixed on a fixing plate 16 and a fixing plate 17 through a connecting shaft 14 and a connecting shaft 15 respectively;

[0029] In order to increase the structural strength of the two-way guide wheel structure 4, a reinforcing plate 20 is provided between the fixing plates 17, and a reinforcing plate 18 and a reinforcing plate 19 are provided before and after the fixing plate 17;

[0030] The fixing plate 17, the reinforcing plate 18 and the reinforcing plate 19 are connected to the main body panel 21;

[0031] The base of the two-way guide wheel structure 4 includes a base panel 22, a base main vertical plate 24, a base bracket 25 and a base bracket 26, and the base is welded on the B-type cabin 1;

[0032] The plates of the main body of the two-way guide wheel structure 4 are all welded together, and the plates of the base of the two-way guide wheel structure 4 are all welded together;

[0033] The base and the main body of the two-way guide wheel structure 4 are connected by connecting bolts 23;

[0034] The slide rail guide structure 5 is arranged at the four corners of the hull hatch, which corresponds to the position of the two-way guide wheel 4 one by one;

[0035] The guide rail guide structure 5 is composed of a steel guide plate 27 and a steel guide plate 28, and is in an oblique shape as a whole, with a large upper opening and a small lower opening;

[0036] A damping and shock absorbing device 6 is provided below the introduction plate 27 and the steel introduction plate 28. The damping and shock absorbing device 6 is connected to the upper and lower fixing plates 39 through the upper and lower connecting shafts 31. The upper and lower fixing plates are respectively connected to the slide rail introduction structure 5 and the deck 3. In order to ensure the structural strength, a reinforcing bracket 30 is provided on the fixing plate 29;

[0037] The deck 3, the fixed plate 29, the reinforcing bracket 30, the lead-in plate 27 and the lead-in plate 28 are all connected by welding;

[0038] The slide rail body 7 is composed of a steel plate 32 and a steel plate 33, and has an L-shaped cross section.

[0039] The fixed base 8 is a steel base, which is located at the hull hatch. The fixed base 8 is composed of a horizontal connecting plate 34, a vertical connecting plate 35 and a vertical connecting plate 36. The function of the fixed base 8 is to rigidly connect the slide rail body 7 and the hull bulkhead 2;

[0040] The elastic base 9 is a steel base, which is located in the middle of the slide rail body 7. The elastic base 9 is composed of a base bottom plate 37, a base panel 38 and a base panel 39. The base panel 38 and the base surface 39 are combined into an L shape, and an L-shaped elastic rubber block 40 is laid on the surface. The slide rail body 7 leans on the elastic rubber block 40. There is only a leaning relationship between the slide rail body 7 and the elastic rubber block, and there is no fixed connection;

[0041] The adjustment base 10 is a steel base, which is located at the end of the slide rail body 7. The adjustment base 10 is composed of a base bottom plate 41, a base panel 42 and a base panel 43. The base panel 42 and the base surface 43 are combined into an L shape;

[0042] Four top screws are respectively provided on the base panel 42 and the base surface 43. The top screw 44 has an inner hexagonal groove at the head, and the top screw 44 has an external thread. The top screw holes on the base panel 42 and the base surface 43 have an internal thread. The top screw 44 can be rotated using an inner hexagonal wrench 45 to make the top screw close to or away from the slide plate 32 and the plate 33, thereby adjusting the lateral position and longitudinal position of the end of the slide rail body 7.

[0043] When the B-type cabin 1 is hoisted into the cabin 2, the two-way guide wheel structure 4 on the B-type cabin 1 in the swaying state first collides with the slide rail introduction structure 5, and the slide rail introduction structure 5 undergoes elastic deformation under the collision, compressing the damping and shock absorbing device 6, forcing the damping and shock absorbing device 7 to be compressed and absorb the collision energy, and then the B-type cabin 1 leaves the introduction structure 5 and swings to the other end, and its swing amplitude and speed are reduced, and the damping and shock absorbing device 7 quickly returns to its original state under the action of the deformation rebound force of the slide rail; the B-type cabin 1 collides between the slide rail introduction structures 5 back and forth in this way and slowly falls, and its swing amplitude and speed become smaller and smaller.

[0044] The B-type cabin 1 gradually stabilizes and is lowered, so that the B-type cabin 1 falls along the slide rail body 7 through the two-way guide wheel structure 4; during this period, if the B-type cabin 1 is shaken by an external force, since it is constrained by the slide rail body 7, the shaking amplitude of the B-type cabin 1 is very small, and the impact of the B-type cabin 1 on the slide rail body 7 will be absorbed by the elastic deformation of the elastic rubber block 40, and the B-type cabin 1 and the slide rail 6 will not be damaged.

[0045] Before the B-type cabin 1 and the two-way guide wheel structure 4 enter the end of the slide rail body 7, the spatial position data of the B-type cabin 1 and the saddle 3 are measured. According to the measurement results, the hexagonal wrench 45 is used to rotate the top screw 44 to adjust the end position of the slide rail body 7.

[0046] The B-type cabin 1 is lowered to the bottom, and under the constraint and guidance of the end of the slide rail body 7, the B-type cabin 1 enters the target position, thereby completing the precise positioning of the B-type cabin in the length direction and the width direction of the ship.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
