Description

Technical Field

[0001] This invention relates to the field of ship and marine structure construction technology, and in particular to a three-phase adjustable segmented fixing device and its working method. Background Technology

[0002] In modern shipbuilding, the modular construction method is widely used due to its efficiency and flexibility. This method involves dividing the hull into several sections, prefabricating, assembling, and welding them one by one, and finally assembling these sections into a complete hull structure. This method not only accelerates the construction process but also effectively reduces costs, making it the primary method for producing medium and large-sized ships. To ensure the positional accuracy and stability of the sections during the assembly process, section fixing devices have been developed, primarily used for positioning, supporting, and securing the sections to improve welding and assembly quality.

[0003] However, existing segmented fixing devices still have some shortcomings. Many devices are structurally complex and cumbersome to operate, increasing the workload of installation and dismantling and affecting construction efficiency. In addition, some fixing devices have poor adaptability and cannot meet the changing needs of different segmented structures, especially when dealing with segments of varying sizes and shapes, where adjustments are not flexible enough. Summary of the Invention

[0004] The main technical problem to be solved by this invention is the inconvenience of installing and the inflexibility of adjusting the ship section structure. In order to overcome the above-mentioned defects of the prior art, a three-phase adjustable section fixing device and its working method are provided.

[0005] The technical solution adopted by this invention to solve its technical problem is: A three-way adjustable hull section fixing device includes a three-way adjustable hull section fixing platform and four movable section lifting lug fixing devices. The four movable section lifting lug fixing devices are symmetrically arranged at the four corners of the three-way adjustable hull section fixing platform. Each movable section lifting lug fixing device includes a section fixing module, a dynamic positioning module, and an electric locking module. The dynamic positioning module is connected to the section fixing module and limits the setting position of the section fixing module. The electric locking module is connected to the section fixing module, and the section lifting lug to be fixed is installed on the section fixing module through the electric locking module.

[0006] Furthermore, the segmented fixing module includes a U-shaped track, an I-shaped slider, a fixing lug, and a lug pin. The U-shaped track is fixedly installed on the three-way adjustable hull segment fixing platform, and the lower wing plate of the I-shaped slider is fitted with the U-shaped track.

[0007] Furthermore, there are two fixed lifting lugs, which are respectively located at the left and right ends of the upper part of the I-shaped slider.

[0008] Furthermore, the lifting lug pin is inserted into the fixed lifting lug and the segmented lifting lug that needs to be fixed.

[0009] Furthermore, the dynamic positioning module includes a slideway worm gear motor, a slideway worm gear motor pad, a slideway worm wheel, a slideway worm, and a slideway worm gear bearing. The slideway worm gear motor pad is mounted on a three-way adjustable hull section fixing platform, and the slideway worm gear motor is mounted on the slideway worm gear motor pad. The slideway worm gear motor and the slideway worm wheel are connected through the slideway worm gear bearing.

[0010] Furthermore, the slide worm gear is coupled with a slide worm wheel motor, which drives the slide worm gear to move. A self-locking structure is provided between the slide worm wheel and the slide worm gear.

[0011] Furthermore, the slide worm gear is connected to the center of the upper wing plate of the I-shaped slider.

[0012] Furthermore, the electric locking module includes a pin-mounted worm gear motor, a pin-mounted motor pad, a pin-mounted worm gear, and a pin-mounted worm. The pin-mounted motor pad is fixedly mounted on a three-way adjustable hull section fixing platform. The pin-mounted worm gear motor is mounted on the pin-mounted motor pad. The pin-mounted worm gear motor and the pin-mounted worm gear are connected through a pin-mounted worm gear bearing. The pin-mounted worm and the pin-mounted worm gear cooperate with each other, and a self-locking structure is provided between the pin-mounted worm gear and the pin-mounted worm.

[0013] Furthermore, the worm gear is connected to the lug pin, and the central axis of the worm gear coincides with the central axis of the lug pin.

[0014] A method for operating a three-way adjustable hull section fixing device includes the following steps: S1. After the ship section structure enters the three-way adjustable hull section fixing platform, the dynamic positioning module adjusts the position of the fixing lugs according to the size and shape of the ship section, so that it is concentrically aligned with the lugs of the section to be fixed. S2. The electric locking module pushes the lifting lug pin to move, so that it is inserted into the lifting lug of the section fixing module and the section to be fixed, so as to achieve a tight connection between the section fixing device and the ship section structure. S3. After the splicing and flipping of the ship section structure are completed, the worm gear motor in the electric locking module drives the worm to pull the lifting lug pin, so that it is pulled away from the fixed lifting lug and the section lifting lug to be fixed, thus completing the separation of the section fixing device from the ship section structure. S4. The ship section splicing operation is completed, and the dynamic positioning module drives the section fixing module to reset.

[0015] The beneficial effects of this invention are: This invention mainly consists of a three-way adjustable hull section fixing platform, a section fixing module, an electric locking module, and a dynamic positioning module. The dynamic positioning module precisely adjusts the position of the fixing lugs according to the section size, and then the electric locking module achieves a stable locking connection, ensuring the convenience, stability, and safety of ship sections during splicing and flipping. This device significantly improves operational adaptability and efficiency, ensures the reliability of large ship section structures during hoisting, and provides technical support for efficient and safe ship section construction.

[0019] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0020] Figures 1 to 7As shown, this invention discloses a three-way adjustable hull section fixing device, including a three-way adjustable hull section fixing platform 1 and four movable section lifting lug fixing devices 2, as follows: Figure 1 As shown, the four movable segment lifting lug fixing devices 2 are symmetrically arranged at the four corners of the three-way adjustable hull segment fixing platform 1 to fix the ship segment structure. The ship segment structure enters the three-way adjustable hull segment fixing platform 1 and is fixed by the movable segment lifting lug fixing devices 2 to complete related operations such as turning over and splicing.

[0021] Reference Figure 2 As shown, the movable segmented lifting lug fixing device 2 includes a segmented fixing module 4, a dynamic positioning module 5, and an electric locking module 6. The segmented fixing module 4 is equipped with the segmented lifting lugs 3 to be fixed. The dynamic positioning module 5 is used to determine the exact position of the segmented fixing module 4, and the electric locking module 6 is used to automatically fix the ship's segmented structure. Both the dynamic positioning module 5 and the electric locking module 6 adopt automated control methods to achieve precise positioning and locking of the segments without manual intervention.

[0022] Reference Figure 3 As shown, the segmented fixing module 4 includes a U-shaped track 4a, an I-shaped slider 4b, fixing lugs 4c, and lug pins 4d. The U-shaped track 4a is fixedly mounted on the three-way adjustable hull segment fixing platform 1. The lower flange of the I-shaped slider 4b is fitted into the U-shaped track 4a, and the fitted part is coated with lubricant. There are two fixing lugs 4c, which are respectively located at the left and right ends of the upper part of the I-shaped slider 4b. The lug pins 4d are inserted into the fixing lugs 4c and the segmented lifting lugs 3 to be fixed.

[0023] Reference Figure 4 and Figure 5 As shown, the dynamic positioning module 5 includes a sliding worm gear motor 5a, a sliding worm gear motor pad 5b, a sliding worm gear 5c, a sliding worm 5d, and a sliding worm gear bearing 5e. The sliding worm gear motor pad 5b is mounted on the three-way adjustable hull section fixing platform 1. The sliding worm gear motor 5a is mounted on the sliding worm gear motor pad 5b, and the sliding worm gear motor 5a and the sliding worm gear 5c are connected via the sliding worm gear bearing 5e. The sliding worm 5d cooperates with the sliding worm gear motor 5a, and the sliding worm gear motor 5a drives the sliding worm 5d to move. The sliding worm gear 5c and the sliding worm 5d are designed with a self-locking structure, meaning that only the sliding worm gear 5c can drive the sliding worm 5d to move back and forth; the sliding worm 5d cannot drive the sliding worm gear 5c to rotate. The worm gear 5d of the slide is connected to the center of the upper wing plate of the I-shaped slider 4b.

[0024] In use, the slide rail worm gear motor 5a drives the slide rail worm 5d to complete the movement operation of the I-shaped slider 4b on the U-shaped track 4a, so as to adapt to ship section structures of different sizes and shapes and realize the dynamic positioning function of the movable section lifting lug fixing device 2.

[0025] Reference Figure 6 and Figure 7 As shown, the electric locking module 6 includes a pin-and-worm gear motor 6d, a pin-and-worm motor pad 6c, a pin-and-worm wheel 6b, and a pin-and-worm 6a. The pin-and-worm motor pad 6c is fixedly mounted on the three-way adjustable hull section fixing platform 1. The pin-and-worm gear motor 6d is mounted on the pin-and-worm motor pad 6c, and the pin-and-worm gear motor 6d and the pin-and-worm wheel 6b are connected via a pin-and-worm gear bearing 6e. The central axis of the pin-and-worm 6a coincides with the central axis of the lifting lug pin 4d, and the pin-and-worm 6a is connected to the lifting lug pin 4d. The pin-and-worm 6a cooperates with the pin-and-worm wheel 6b. The pin-and-worm gear motor 6d drives the pin-and-worm 6a to move. The pin-and-worm wheel 6b and the pin-and-worm 6a are designed with a self-locking structure, meaning that only the pin-and-worm wheel 6b can drive the pin-and-worm 6a to move back and forth; the pin-and-worm 6a cannot drive the pin-and-worm wheel 6b to rotate.

[0026] The pin worm gear motor 6d drives the pin worm gear 6a to move, and the pin worm gear 6a pushes the lifting lug pin 4d to insert into the fixed lifting lug 4c and the segment lifting lug 3 that needs to be fixed, so as to realize the locking operation between the segment fixing module 4 and the ship segment structure.

[0027] When using this invention, the segmented lifting lugs 3 to be fixed are set on the ship segment structure to be spliced. The electric locking module 6 drives the lifting lug pin 4d to move back and forth to achieve automatic locking and separation between the fixed lifting lug 4c and the segmented lifting lug 3 to be fixed. After completing the splicing and other related operations of the ship segment structure, the electric locking module 6 drives the lifting lug pin 4d to pull away from the fixed lifting lug 4c and the segmented lifting lug 3 to be fixed. After the ship segment structure is separated from the movable segmented lifting lug fixing device 2, the dynamic positioning module 5 drives the I-shaped slider 4b to move, completing the reset of the segment fixing module 4. This invention effectively solves the problems of inconvenient installation and inflexible adjustment of ship segment structures by automatically completing the installation and disassembly of ship segments and dynamically adjusting the position of the fixing device.

[0028] This invention also discloses a method for operating a three-way adjustable hull section fixing device, comprising the following steps: S1. After the ship section structure enters the three-way adjustable hull section fixing platform 1, the dynamic positioning module 5 adjusts the position of the fixing lug 4c according to the size and shape of the ship section, so that it is concentrically aligned with the lifting lug 3 of the section to be fixed. Specifically, driven by the slide worm gear motor 5a, the slide worm 5d pushes the I-shaped slider 4b to move within the U-shaped track 4a, so that the fixing lug 4c moves to the ship section equipped with the lifting lug, and is concentrically aligned with the lifting lug 3 of the section to be fixed.

[0029] S2. The electric locking module 6 pushes the lifting lug pin 4d to move, causing it to insert into the segment fixing module 4 and the segment lifting lug 3 to be fixed, thus achieving a tight connection between the segment fixing device and the ship segment structure. Specifically, the pin worm gear motor 6d pushes the pin worm 6a to move, and the pin worm 6a further pushes the lifting lug pin 4d to insert into the fixing lifting lug 4c and the segment lifting lug 3 to be fixed, ensuring alignment at the center and achieving a tight connection between the segment fixing device and the ship segment structure.

[0030] S3. After the ship section structure has completed splicing, flipping and other related operations, the pin worm gear motor 6d in the electric locking module 6 drives the worm to pull the lifting lug pin 4d, so that it is pulled away from the fixed lifting lug 4c and the section lifting lug 3 that needs to be fixed, thus completing the separation of the section fixing device from the ship section structure.

[0031] S4. The ship section splicing operation is completed, and the dynamic positioning module 5 drives the section fixing module 4 to reset.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
