Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a shock-resistant interconnection channel and installation method for a marine frame unit. Background Technology

[0002] Large liquefied gas carriers typically have a compressor room, with an overall structural height of about 5 meters. Inside the compressor room, there are usually three reliquefaction units, with a frame structure and a height of about 2.6 meters. For ease of maintenance, a ladder is usually installed at the stern for safety inspection and maintenance personnel to move up and down. Because the reliquefaction units are equipped with motors and other power equipment, the entire unit vibrates during operation, which can damage components and other equipment over time.

[0003] To prevent vibration, multiple large I-beams, each over 2 meters tall, are typically welded directly to the upper deck structure from the four corners of the frame. Because these I-beams are tall and heavy, installation is very inconvenient in the later stages (the reinforcing ribs supporting the upper deck can only be installed after the hull structure is plated). Since the upper deck structure has already been plated and installed, it is difficult to lift the vertical reinforcing I-beams using cranes such as truck cranes or gantry cranes. After the plate is plated, due to the limitations of the overall cabin structure, there is still a certain risk of lifting during installation.

[0004] Furthermore, during maintenance, once construction workers have finished repairing one reliquefaction unit, they must use a vertical ladder next to the reliquefaction unit to return to the deck, walk a few more steps, and then climb the ladder of the second or third reliquefaction unit to reach the top of the frame unit. This climbing up and down and detours for maintenance work is very inconvenient. In addition, the electrical equipment supports used to be separate supports, independently supported on the deck, which were prone to swaying. How to integrate them with the frame is also an aspect that needs to be considered.

[0005] Therefore, how to eliminate the reinforcing ribs supporting the upward-facing frame unit, prevent the entire frame unit from vibrating, allow multiple reliquefaction units to move back and forth between their tops, integrate with the electrical equipment support structure for easy maintenance and operation, and prevent vibration of the electrical equipment is a technical challenge that technicians need to solve. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a shock-resistant interconnection channel and installation method for marine frame units. This invention connects frame units using a channel device to prevent vibration of the entire unit later. Furthermore, the channel device is integrated with electrical equipment, effectively solving the problems of inconvenience for construction personnel during maintenance and vibration. Moreover, this invention can be installed using a truck crane or gantry crane before the initial plate sealing stage, improving shipbuilding efficiency.

[0007] To achieve the above and other related objectives, the present invention provides a shock-resistant interconnection channel for a marine frame unit, the shock-resistant interconnection channel comprising:

[0008] Two parallel first support beams are provided, and a first steel plate is welded to the center of both ends of the two first support beams. The first steel plate has four evenly distributed round holes. The first support beams are connected by angle steel. Multiple angle steels are arranged along the length of the first support beams. A corrugated steel plate is laid on top of the angle steel to form a passage for people to walk.

[0009] The earthquake-resistant interconnection channel is used to be erected between two adjacent frame units. The first frame unit is located on the left side of the earthquake-resistant interconnection channel, and the second frame unit is located on the right side of the earthquake-resistant interconnection channel.

[0010] The first frame unit includes a square frame, and a right transition platform is connected to the upper right edge of the square frame. The right transition platform includes two parallel second support beams. A second steel plate is welded to the center of the end face of the second support beam away from the square frame. The second steel plate has four evenly distributed round holes, and the round holes of the second steel plate match those of the first steel plate.

[0011] The second frame unit includes a square frame, with a left transition platform connected to the upper left edge of the square frame. The left transition platform includes two parallel third support beams. A third steel plate is welded to the center of the end face of the third support beam away from the square frame. The third steel plate has four evenly distributed circular holes, which match the circular holes of the first steel plate.

[0012] Optionally, the first support beam, the second support beam, and the third support beam are all I-beams.

[0013] Optionally, an electrical equipment bracket for placing electrical equipment is provided on one side of the bottom of the frame unit, and a straight ladder is also fixed on one side of the frame unit.

[0014] Optionally, the first support beam and the second support beam, and the first support beam and the third support beam, form an angle of 120-180°.

[0015] Optionally, horizontal and vertical steel strips are welded to the outer walls of the two first support beams that are far apart from each other. The vertical steel strips are located outside the horizontal steel strips. The horizontal steel strips are arranged in a direction parallel to the first support beams. The vertical steel strips are perpendicular to the first support beams and multiple vertical steel strips are arranged along the length of the first support beams. The middle and upper ends of the vertical steel strips are welded with steel pipes parallel to the first support beams. The vertical steel strips and steel pipes form a guardrail.

[0016] Optionally, the outer walls of the two second support beams, which are far apart from each other, are welded with transverse steel strips and vertical steel strips. The vertical steel strips are perpendicular to the second support beams and multiple vertical steel strips are arranged along the length of the second support beams. The middle and upper ends of the vertical steel strips are welded with short steel pipes parallel to the second support beams.

[0017] Optionally, the outer walls of the two third support beams, which are far apart from each other, are welded with horizontal steel strips and vertical steel strips. The vertical steel strips are perpendicular to the third support beams, and each vertical steel strip is located at the end of the third support beam away from the square frame. The middle and upper ends of the vertical steel strips are welded with short steel pipes parallel to the third support beams.

[0018] The present invention also provides a method for installing the aforementioned shockproof interconnection channel, comprising the following steps:

[0019] S1, Platform Phase: Install the three frame units onto the deck;

[0020] S2, Platform Stage: The two anti-seismic interconnection channels assembled from various components are hoisted between two adjacent frame units using shipyard cranes or gantry cranes.

[0021] S3, Platform Stage: Insert the set of bolts and nuts between the first steel plate with round holes and the second steel plate with round holes for fastening. In the same way, insert the set of bolts and nuts between the first steel plate with round holes and the third steel plate with round holes for fastening.

[0022] S4. Butt weld the short steel pipes of the frame unit to the steel pipes of the seismic interconnection channel.

[0023] S5. Repeat steps S2 to S4 using the same method to install each anti-vibration interconnection channel in place;

[0024] S6. Secure the electrical equipment directly to the electrical equipment bracket to complete the entire installation process.

[0025] As described above, the present invention provides a shock-resistant interconnection channel and installation method for marine frame-type units, which has the following beneficial effects:

[0026] Previously, maintenance on the top of each frame unit required climbing up and down a vertical ladder installed on the side, then circling around to the ground deck, and finally climbing to the top of another frame unit for maintenance. This was inconvenient due to the long distances involved. Furthermore, to prevent vibration during later operation, frame units typically had multiple large I-beams welded to the top of the deck as reinforcing ribs. These ribs were installed only after the top deck was completed, and their height and weight posed a significant installation risk. Additionally, the electrical equipment controlled by the installed units was located in nearby independent frames, making it susceptible to vibration and potential damage. This invention addresses these shortcomings by eliminating the top supporting reinforcing ribs and employing a lateral interlocking vibration damping system. The interlocking components were replaced with a passageway device, which, while providing vibration damping, also added a top-level bridge passageway. Maintenance personnel could move directly between multiple frame units, reducing the need to climb vertical ladders. This bridge passageway could be installed during the platform stage, immediately after the frame units were installed. After installation, the electrical equipment for the control system could be installed, eliminating the need for later stages and improving construction efficiency. This invention has been applied to large liquefied gas carriers with remarkable results, and its adoption will continue, demonstrating its high value for promotion. Attached Figure Description

[0050] Example 1

[0051] like Figures 1 to 4 As shown, this embodiment provides a shock-resistant interconnection channel for a marine frame unit, the shock-resistant interconnection channel 100 including:

[0052] Two parallel first support beams 101 are constructed, with I-beams serving as the main supports. A first steel plate 102 is welded to the center of each end face of the two first support beams. The first steel plate 102 has four evenly distributed circular holes 108. The first support beams 101 are connected by angle steel 105, with multiple angle steels 105 arranged along the length of the first support beams. A perforated steel plate 109 is laid flat above the angle steel 105 to form a passageway for personnel.

[0053] Two mutually distant outer walls of the first support beams 101 are welded with horizontal steel strips 103 and vertical steel strips 104. The vertical steel strips 104 are located outside the horizontal steel strips 103. The horizontal steel strips 103 are arranged in a direction parallel to the first support beams 101. The vertical steel strips 104 are perpendicular to the first support beams 101, and multiple vertical steel strips 104 are arranged along the length of the first support beams 101. The middle and upper ends of the vertical steel strips 104 are welded with steel pipes (including steel pipes 106 and 107) parallel to the first support beams 101. The vertical steel strips 104 and steel pipes form a guardrail to prevent people from falling.

[0054] The earthquake-resistant interconnection channel 100 is used to be installed between two adjacent frame units, see reference. Figure 13 The first frame unit 200 is located on the left side of the seismic interconnection channel, and the second frame unit 300 is located on the right side of the seismic interconnection channel. An electrical equipment bracket 310 for placing electrical equipment is provided on one side of the bottom of the frame unit, and a straight ladder 2 is also fixed on one side of the frame unit.

[0055] like Figures 5 to 7 As shown, the first frame unit 200 includes a square frame. The upper right edge of the square frame is connected to a right transition platform. The right transition platform includes two parallel second support beams 201. The second support beams 201 also use I-beams as the main supports. The second support beams 201 are at the same height as the top surface of the square frame. A second steel plate 202 is welded to the center of the end face of the second support beam 201 away from the square frame. The second steel plate 202 has four evenly distributed circular holes 208. The circular holes of the second steel plate 202 match those of the first steel plate 102.

[0056] The outermost walls of the two mutually distant second support beams 201 are welded with transverse steel strips 203 and vertical steel strips 204. The vertical steel strips 204 are perpendicular to the second support beams 201, and multiple vertical steel strips 204 are arranged along the length of the second support beams 201. Short steel pipes (including short steel pipes 206 and 207) parallel to the second support beams 201 are welded to the middle and upper ends of each vertical steel strip 204. The two second support beams 201 are connected by angle steel 205 to form a walking passage.

[0057] like Figures 8 to 10As shown, the second frame unit 300 includes a square frame. The upper left edge of the square frame is connected to a left transition platform. The left transition platform includes two parallel third support beams 301. The third support beams 301 also use I-beams as the main supports. The third support beams 301 are at the same height as the top surface of the square frame. A third steel plate 302 is welded to the center of the end face of the third support beam 301 away from the square frame. The third steel plate 302 has four evenly distributed circular holes 308. The circular holes of the third steel plate 302 match those of the first steel plate 102.

[0058] The outer walls of the two third support beams 301, which are far apart from each other, are welded with horizontal steel strips 303 and vertical steel strips 304. The vertical steel strips 304 are perpendicular to the third support beams 301 and each vertical steel strip 304 is located at the end of the third support beam 301 away from the square frame. The middle and upper ends of the vertical steel strips 304 are welded with short steel pipes (including short steel pipes 306 and 307) parallel to the third support beams 301.

[0059] When the earthquake-resistant interconnection channel is connected to the transition platform, the steel pipe of the earthquake-resistant interconnection channel is connected to the short steel pipe of the transition platform.

[0060] It should be noted that the first support beam 101 and the second support beam 201, and the first support beam 101 and the third support beam 301 are not located on the same straight line, but can also form an angle, with the angle being 120-180°.

[0061] Based on the aforementioned anti-vibration interconnection channel, this embodiment also provides a corresponding installation method, including the following steps:

[0062] S1, Platform Stage, such as Figure 11 As shown, three frame units are installed on deck 1, including the first frame unit 200, the second frame unit 300, and the third frame unit 400, which are installed on deck 1 according to the drawing requirements.

[0063] S2, Platform Stage, such as Figure 12 As shown, the two anti-vibration interconnection channels, which are assembled from various components, are hoisted into the space between two adjacent frame units using a shipyard crane or gantry crane, including between the first frame unit 200 and the second frame unit 300, and between the second frame unit 300 and the third frame unit 400.

[0064] S3, Platform Stage, such as Figures 13 to 15As shown, the set of bolts and nuts 3 are inserted between the first steel plate 102 with round holes 108 and the second steel plate 202 with round holes 208 for fastening. Similarly, the set of bolts and nuts 4 are inserted between the first steel plate 102 with round holes 108 and the third steel plate 302 with round holes 308 for fastening.

[0065] S4. Butt weld the short steel pipes 206, 207, 306 and 307 to the two ends of the steel pipes 106 and 107 respectively.

[0066] S5. Repeat steps S2 to S4 in the same way to install the remaining channel devices in place.

[0067] S6. Secure the electrical equipment 311 directly to the electrical equipment bracket 310 to complete the entire installation process. Figure 16 As shown.

[0068] In summary, this invention provides a shock-resistant interconnection channel and installation method for marine frame-type units. This shock-resistant interconnection channel allows for the interlocking and fixing of frame-type units during the platform stage, preventing vibrations caused by motor operation later. Furthermore, the frame-type units are integrated with the electrical equipment of the control unit system. Verified on actual ships, the method is effective, reliable, easy to operate, and improves construction efficiency. This invention not only solves the vibration problem but also provides a convenient and safe passage for maintenance personnel in the top area, reduces the difficulty of later installation of the top support I-beams, reduces the weight of the I-beam raw materials, and directly fixes the electrical equipment to the unit, making it an integrated unit, which greatly facilitates later control and maintenance of the electrical equipment. This invention has already been applied to large liquefied gas carriers with significant results and has high promotional value.

[0069] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
