Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, in particular to a shockproof interconnection channel of a marine frame unit and an installation method thereof. Background Art

[0002] Large liquefied gas carriers typically have a compressor room, typically around 5 meters tall. Inside, three reliquefaction units are typically installed. These units are framed and approximately 2.6 meters tall. For easy access, a vertical ladder is typically installed at the stern for security and maintenance personnel. Because the reliquefaction units are equipped with motors and other power equipment, they vibrate during operation, potentially damaging components and other equipment.

[0003] In order to prevent vibration, multiple large I-beams more than 2 meters in length are usually welded vertically directly to the upper deck structure at the four corners of the frame for reinforcement. Since these I-beams are tall and heavy, it is very inconvenient to install them in the later stage (the reinforcement ribs supporting the upper deck can only be constructed after the hull structure is sealed). Since the upper deck structure has been sealed and installed, the vertical reinforcing I-beams are difficult to lift with lifting equipment such as car cranes or gantry cranes. After the sealing, due to the limitation of the overall cabin structure, there is still a certain lifting risk during installation.

[0004] Furthermore, during maintenance, once construction workers have climbed up one reliquefaction unit for maintenance, to get to another reliquefaction unit, they must return to the deck via the vertical ladder on the side of the reliquefaction unit, walk a few 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 taking a detour to perform maintenance work is very inconvenient. In addition, the electrical equipment brackets were previously supported by separate brackets and independently supported on the deck, which were prone to shaking. How to integrate them with the frame is also an aspect that needs to be considered.

[0005] Therefore, how to remove the reinforcement ribs that support the frame unit upward while preventing the entire frame unit from vibrating, allowing people to move back and forth between the tops of multiple reliquefaction units, and integrating the structure with the electrical equipment bracket to facilitate maintenance and operation and prevent electrical equipment from vibrating is a technical problem that technicians need to solve. Summary of the Invention

[0006] In light of the shortcomings of the prior art, the present invention aims to provide a vibration-proof interconnecting channel and installation method for marine frame units. This invention connects the frame units with a channel device to prevent subsequent vibration of the entire unit. The channel device is integrated with the electrical equipment, effectively resolving the issues of inconvenient maintenance and vibration for construction personnel. Furthermore, this invention allows installation by crane, truck crane, or gantry crane before the initial paneling, improving shipbuilding efficiency.

[0007] To achieve the above-mentioned and other related purposes, the present invention provides a seismic-proof interconnection channel of a marine frame unit, the seismic-proof interconnection channel comprising:

[0008] Two parallel first support beams, with first steel plates welded in the middle of both end faces of the two first support beams, each with four evenly distributed circular holes. The first support beams are connected by angle steels, and multiple angle steels are arranged along the length of the first support beams. A decorative steel plate is laid on top of the angle steels to form a pedestrian passage;

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

[0010] The first frame unit includes a square frame body, the upper right edge of the square frame body is connected outwardly to a right transition platform, the right transition platform includes two parallel second support beams, the end surface of the second support beam away from the square frame body is centrally welded with a second steel plate, the second steel plate is provided with four evenly distributed circular holes, and the second steel plate matches the circular holes of the first steel plate;

[0011] The second frame unit includes a square frame body, and the upper left edge of the square frame is connected outwardly to a left transition platform. The left transition platform includes two parallel third support beams. The end surface of the third support beam away from the square frame is welded with a third steel plate in the center. The third steel plate is provided with four evenly distributed circular holes, and the third steel plate matches 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 vertical ladder is also fixed on one side of the frame unit.

[0014] Optionally, there is an angle between the first support beam and the second support beam, and between the first support beam and the third support beam, and the angle is 120-180°.

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

[0016] Optionally, the outer sides of the two second support beams that are away 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 direction of the second support beams, and 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 side walls of the two third support beams that are away 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 a single vertical steel strip is located at the end of the third support beam away from the square frame, and the middle and upper ends of the vertical steel strips are welded with short steel pipes parallel to the third support beam.

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

[0019] S1, platform stage, installing three frame units onto the deck;

[0020] S2, platform stage: Use the shipyard's crane or gantry crane to hoist the assembled two seismic interconnection channels between the two adjacent frame units;

[0021] S3, platform stage, respectively insert the complete set of bolts and nuts between the first steel plate with a circular hole and the second steel plate with a circular hole and tighten them, and in the same way, insert the complete set of bolts and nuts between the first steel plate with a circular hole and the third steel plate with a circular hole and tighten them;

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

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

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

[0025] As described above, the present invention provides a seismic interconnection channel and installation method for a marine frame unit, which has the following beneficial effects:

[0026] In the past, maintenance on the top of each frame unit required climbing up and down a vertical ladder installed on the side, then detouring to the ground deck and climbing to the top of another frame unit for maintenance. The distance was too far and climbing up and down was inconvenient. In addition, to prevent vibration during operation, the frame units generally had multiple large I-beams welded to the top of the deck as reinforcement ribs. These reinforcement ribs had to be installed at a later stage after the top deck was capped. The reinforcement ribs were tall and heavy, and the installation process was relatively risky. Moreover, the electrical equipment controlled by the installed unit was located in a nearby independent frame and was prone to vibration, which could affect the electrical equipment. The present invention optimizes and improves the above-mentioned defects by eliminating the top support reinforcement ribs and adopting a transverse interlocking vibration isolation. The interlocking components are replaced with a channel device. While providing vibration isolation, it also adds a top bridge channel, allowing maintenance personnel to move directly back and forth between multiple frame units, reducing the need to climb up and down vertical ladders. This bridge channel can be installed at the platform stage after the frame units are installed. After the channel device is installed, the electrical equipment of the control unit system can be installed, eliminating the need for later installation, thereby improving construction efficiency. This invention has been applied to large liquefied gas ships with remarkable results. It will continue to be adopted in the future and has high promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Example 1

[0051] like Figures 1 to 4 As shown, this embodiment provides a seismic interconnection channel of a marine frame unit, and the seismic interconnection channel 100 includes:

[0052] Two parallel first support beams 101 are constructed using I-beams as their primary support. A first steel plate 102 is welded to the center of each end face of the beams. The first steel plate 102 has four evenly spaced circular holes 108. The first support beams 101 are connected by angle steels 105, which are arranged along their lengths. A decorative steel plate 109 is laid above the angle steels 105 to form a pedestrian passage.

[0053] The outer sides of the two first support beams 101 that are away from each other are welded with transverse steel strips 103 and vertical steel strips 104. The vertical steel strips 104 are located on the outside of the transverse steel strips 103. The transverse 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 direction 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 the steel pipes form a guardrail to prevent people from falling.

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

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

[0056] Horizontal steel strips 203 and vertical steel strips 204 are welded to the outer walls of the two second support beams 201, which are spaced apart from each other. The vertical steel strips 204 are perpendicular to the second support beams 201 and are arranged along the length of the second support beams 201. Short steel pipes (including short steel pipes 206 and 207) are welded to the middle and upper ends of the vertical steel strips 204, which are parallel to the second support beams 201. The two second support beams 201 are connected by angle steel 205 to form a walking path.

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

[0058] The outer sides of the two third support beams 301 that are away 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 a single 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 short steel pipes 307) parallel to the third support beam 301.

[0059] When the shockproof interconnection channel is connected to the transition platform, the steel pipe of the shockproof 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 may be at an angle of 120-180°.

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

[0062] S1, platform stage, e.g. Figure 11 As shown, three frame units are installed on the deck 1, including a first frame unit 200, a second frame unit 300 and a third frame unit 400, which are installed on the deck 1 according to the drawing requirements.

[0063] S2, platform stage, e.g. Figure 12 As shown, the two assembled seismic interconnection channels are hoisted between two adjacent frame units using a shipyard crane or a 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, e.g. Figures 13 to 15As shown, the set of bolts and nuts 3 are respectively inserted between the first steel plate 102 with the circular hole 108 and the second steel plate 202 with the circular hole 208 for tightening. The same method is used to insert the set of bolts and nuts 4 between the first steel plate 102 with the circular hole 108 and the third steel plate 302 with the circular hole 308 for tightening.

[0065] S4. Butt-weld the short steel pipes 206, 207, 306, and 307 to both 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, directly fix the electrical equipment 311 to the electrical equipment bracket 310 to complete the entire installation process, such as Figure 16 shown.

[0068] In summary, the present invention provides a shockproof interconnection channel and installation method for a marine frame unit. The shockproof interconnection channel can interlock and fix the frame unit with each other at the platform stage to prevent vibration when the motor is running later, and the electrical equipment of the frame unit and the control unit system are integrated. After verification on an actual ship, the method is effective and reliable, easy to operate, and the construction efficiency is also improved. This invention method not only solves the vibration problem, but also provides a convenient and safe passage for maintenance personnel in the top area, and alleviates the difficulty of later installation of the top support I-beam, while reducing the weight of the I-beam raw materials, and the electrical equipment is directly fixed on the unit to form an integrated unit, which makes the later control and maintenance of the electrical equipment very convenient. This invention has been applied to large liquefied gas ships with significant effects and high promotion value.

[0069] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
