Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship and ocean engineering technology, in particular to a unit module hoisting anti-deformation structure and a flexible binding method. BACKGROUND

[0002] Most of the equipment of the ship and ocean engineering is densely arranged, has high functional integration, and is space-limited. In the construction process, it is necessary to optimize the construction process, shorten the construction period, and improve the construction environment to achieve the purpose of safe and efficient construction. At present, advanced ship and ocean engineering construction technology adopts modular design and manufacturing of mechanical and electrical equipment, systems, and piping. Due to the high integration of the construction project, the cabin is divided into many parts and the space is narrow, which makes it difficult to divide the ship and ocean engineering construction section. Not only the engineering structure characteristics need to be considered, but also the cabin and equipment system integrity need to be considered. At the same time, the division of the section should be reasonable to facilitate the design and overall hoisting of the unit, and the unit should not affect the closing of the subsequent connecting section and the total section after being hoisted in place. The requirement for the division of the section is to design an open section that is beneficial to the cabin outfitting, instead of a closed or semi-closed section, to create favorable conditions for the subsequent empty hoisting and rapid hoisting of the unit.

[0003] A hoisting frame and hoisting process for overall hoisting of a ship superstructure are disclosed in Chinese patent ZL 200710158987.X. The hoisting frame for overall hoisting of the ship superstructure adopts a whole frame structure, the transverse member and the longitudinal member are both I-shaped section beams composed of an upper panel, a vertical panel, and a lower panel, which are rigid and light in weight; a row of lifting holes is arranged at the lower part of the vertical panel close to the lower panel, which can be conveniently installed according to the optimized design lifting point. The hoisting frame can meet the needs of different ships, the connection between the hoisting frame and the ship superstructure is convenient, the hoisting process is simple, the overall hoisting can be realized without changing the structure of the superstructure, and the deformation during hoisting is effectively controlled.

The welding type lifting ring hoisting form is prone to cause thermal deformation and has high cost.

[0040] The following refers to Figures 1-5 The unit module hoisting anti-deformation structure and the flexible binding method according to the embodiment of the present application are described.

[0041] As Figures 1-5 shown, the main effect of the unit module hoisting anti-deformation structure is to change the traditional steel structure rigid hoisting form to adopt the flexible hoisting binding method of canceling the lifting ring installation, increase the overall structural rigidity of the hoisting unit module 100, thereby avoiding deformation quality accidents during the hoisting process of the unit module 100, and the flexible binding is convenient to disassemble, can be reused, and reduces the production and hoisting cost.

[0042] The traditional separate rigid lifting frame hoisting method is heavy and easy to scatter, and there are safety hazards in the hoisting process. The welding type lifting ring hoisting form causes thermal deformation and high cost. It is difficult to find a suitable lifting ring lifting point position, and the welding of the lifting ring with the unit part causes unit damage and damage to the coating. The unit is not rigid enough, and deformation occurs during hoisting, and even parts are scattered and damaged, the installation error is large, and the on-site repair amount is large. The flexible binding hoisting technology is adopted, a flexible hoisting method with simple structure, convenient use and reliable performance is designed, the shortcomings of the conventional hoisting method are overcome, a safe and efficient, economical and practical hoisting method is provided, the hoisting process and installation precision and quality of the unit module 100 are ensured, and the period of the piping unit hoisting and installation is shortened.

[0043] The unit module hoisting anti-deformation structure of the present application comprises a unit module 100, an auxiliary lifting frame 200 and a flexible binding piece 300. The unit module 100 is erected in the piping unit of the ship, i.e. the pipe outfitting unit, the position of the fixed part is adjusted according to the shape of the pipe outfitting unit, so that the unit module 100 can fix the overall structure of the pipe outfitting unit and prevent the connection from loosening during hoisting.

[0044] The auxiliary hanger 200 is detachably connected with the unit module 100, and the auxiliary hanger 200 is used for hoisting the unit module 100, so as to hoist the ship pipeline unit; the hoisting equipment hoists the auxiliary hanger 200, so as to hoist the entire pipeline outfitting unit and the unit module 100.

[0045] The unit module 100 comprises a unit module rod 101, the unit module rod 101 is connected with the auxiliary hanger 200 through the flexible binding member 300, and the auxiliary hanger 200 adjusts the arrangement layout according to the position of the unit module rod 101. When the unit module 100 adjusts the position of the unit module rod 101 according to the structure of the pipeline outfitting unit, the auxiliary hanger 200 is arranged according to the position of the unit module rod 101, so that the auxiliary hanger 200 and the unit module rod 101 are fixed through the flexible binding member 300, and a rigid whole is formed.

[0046] The unit module hoisting anti-deformation structure has the following advantages:

[0047] 1. The technical scheme can be applied to ship and marine anti-deformation hoisting, and meets the hoisting strength requirement.

[0048] 2. The technical scheme has simple structure, and greatly improves the hoisting strength requirement of the unit module 100.

[0049] 3. The technical scheme has a lifting ring, and is not easy to produce welding deformation, meets the ship module hoisting and installation construction requirement, and improves the installation quality.

[0050] 5. The technical scheme has simple structure and convenient use, provides a reliable unit module 100 hoisting and binding simple method, overcomes the deficiency of the conventional hoisting method, provides a safe and efficient, economical and practical hoisting method, ensures the installation precision and quality of the unit module 100, shortens the hoisting and installation period of the outfitting pipeline unit. The shape and size of the ship module can be adjusted, a variable combination type is realized, a safe and efficient hoisting method is provided, the deficiency of the conventional unit hoisting is overcome, and the key technical problem in the industry is solved.

[0051] 6. The professional field self-made, factory cooperation or purchase can be realized, so that the construction environment is improved. The site occupation is saved, the work efficiency is improved, the construction process is optimized, the construction period is shortened, and the cost is reduced.

[0052] In some embodiments of the present application, as shown in Figures 1-3 The auxiliary hanger 200 comprises an upper auxiliary hanger 201 and a lower auxiliary hanger 202, the upper auxiliary hanger 201 and the lower auxiliary hanger 202 are placed in an upper-lower manner, and the upper auxiliary hanger 201 and the lower auxiliary hanger 202 are cross-connected through a connecting base 203.

[0053] Specifically, the lower auxiliary hangers 202 are uniformly arranged on one side close to the unit module bars 101, facilitating flexible bundling of the lower auxiliary hangers 202 and the unit module bars 101. The upper auxiliary hangers 201 are laid above the lower auxiliary hangers 202, and the upper auxiliary hangers 201 and the lower auxiliary hangers 202 are connected through the connecting bases 203. The connecting bases 203 are metal bases provided with upper and lower connecting hole positions, and are integrally formed. The upper and lower hole positions are connected with the upper auxiliary hangers 201 and the lower auxiliary hangers 202 respectively, facilitating corresponding adjustment of the upper auxiliary hangers 201 and the lower auxiliary hangers 202 according to the positions of the unit module bars 101. The connecting bases 203 are a technical solution known to those skilled in the art, and will not be described in detail in this embodiment.

[0054] In further embodiments, as shown in Figures 1-3 , the spacing between each upper auxiliary hanger 201 is 500mm-2000mm, and the spacing between each lower auxiliary hanger 202 is 500mm-2000mm.

[0055] Specifically, to ensure the overall structural strength of the auxiliary hangers 200, the distance between each upper auxiliary hanger 201 and the distance between each lower auxiliary hanger 202 are adjusted within a specified range, which can ensure that the overall structural strength is maintained within a certain range. The spacing between the auxiliary hangers 200 can be adjusted, and the number can be adjusted according to the weight of the unit module 100, and the multiple combination arrangement structure.

[0056] In further embodiments, as shown in Figures 1-3 , the upper auxiliary hangers 201 and the lower auxiliary hangers 202 are made of steel pipes with a diameter of 50mm-300mm and a thickness of 5mm-12mm. Since the weight and volume of the ship modules are inconsistent, the auxiliary hangers 200 are selected according to different specifications of the ship modules, which can ensure that the anti-deformation structure does not deform during hoisting.

[0057] In some embodiments of the present application, as shown in Figure 2 and Figure 3 , the flexible bundling member 300 includes a steel wire rope 301 and a steel wire rope clamp 302. The diameter of the steel wire rope 301 is 5mm-16mm, and the number of the steel wire rope clamp 302 is 1-3.

[0058] Specifically, to ensure the connection stability between the auxiliary hanger 200 and the unit module rod 101, a steel wire rope 301 is used for flexible binding. The steel wire rope 301 is a helical bundle of steel wires twisted together according to certain rules, meeting the requirements for mechanical properties and geometric dimensions. The steel wire rope 301 consists of steel wires, a core, and lubricant. The steel wire rope 301 is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, winding a certain number of strands into a helical shape. In material handling machinery, it is used for lifting, traction, tensioning, and load bearing. The steel wire rope 301 has high strength, light weight, stable operation, is not easily broken suddenly, and is reliable in operation.

[0059] Using steel wire rope 301 as the flexible binding member 300 of the present invention can provide good binding force and prevent the connection between the components from loosening during the hoisting process.

[0060] In some embodiments of the present invention, such as Figures 2-5 As shown, the intersection of the upper auxiliary hanger 201 and the lower auxiliary hanger 202 is tied with a steel wire rope 301, with at least one loop. The steel wire rope clamp 302 is used to fix the tying position of the steel wire rope 301.

[0061] In this embodiment, the wire rope clamp 302 uses three fixed wire ropes 301 to provide good fixing force for the wire ropes 301 and prevent the wire ropes 301 from loosening.

[0062] In some embodiments of the present invention, such as Figures 2-5 As shown, the unit module member 101 and the auxiliary hanger 200 are bound together by a steel wire rope 301, with at least one loop. A steel wire rope clamp 302 is used to fix the binding position of the steel wire rope 301. In this embodiment, the steel wire rope clamp 302 uses three fixing steel wire ropes 301 to provide good fixing force for the steel wire ropes 301 and prevent the steel wire ropes 301 from loosening.

[0063] The binding components between unit module members 101, the binding components between auxiliary hangers 200, and the binding components between auxiliary hangers 200 and unit module members 101 can be quickly separated. The flexible binding component 300 is easy to disassemble and can be reused repeatedly, reducing structural damage to the unit module 100 and damage to the paint coating, and reducing rework costs during construction.

[0064] In some embodiments of the present invention, the flexible binding method for the anti-deformation structure of the unit module hoisting includes the following steps:

[0065] The outfitting pipe unit is erected and fixed, and the position of the adjustment unit module 100 is matched and connected with the outfitting pipe unit;

[0066] Adjust the spacing between the auxiliary hangers 200 to align the auxiliary hangers 200 with the unit module rods 101.

[0067] Bundling and fixing, the position between the unit module rod 101 and the auxiliary lifting frame 200 is fixed by the flexible binding member 300, forming a rigid whole;

[0068] Hoisting, the hoisting equipment hoists the installation pipe unit through the intersection of the auxiliary lifting frame 200.

[0069] In a further embodiment, the step of lifting frame erection adjustment comprises the following steps: at least one circle of steel wire ropes 301 is bundled between the intersections of the auxiliary lifting frames 200, and the steel wire ropes 301 are fixed by 1-3 steel wire rope clamps 302.

[0070] In a further embodiment, the step of bundling and fixing comprises the following steps: at least one circle of steel wire ropes 301 is bundled between the auxiliary lifting frame 200 and the unit module rod 101, and the steel wire ropes 301 are fixed by 1-3 steel wire rope clamps 302.

[0071] After the unit module 100 of the application is built, the hoisting and installation stage can be installed and welded without lifting rings, and the welding deformation of the unit module 100 is not easy to occur. After the unit module 100 and the auxiliary lifting frame 200 are flexibly bound, a relatively rigid whole structure is formed, and whole hoisting operation is carried out. The flexible binding member 300 is convenient to disassemble and can be repeatedly used, the structural damage and the paint coating damage to the unit module 100 are reduced, and the rework cost in the construction process is reduced.
