[0002] With the deepening development of marine resources and the booming development of the marine communications industry, submarine cables are being used more and more widely. As a key carrier for marine energy transmission and information transmission, the quality and efficiency of submarine cable deployment directly affect the smooth progress of marine engineering and the stable operation of communication networks. During the submarine cable deployment process, suspension equipment plays a crucial role, undertaking the key tasks of fixing, supporting, and guiding the submarine cable.

[0003] Existing submarine cable laying equipment and suspension fixtures have numerous limitations in their connection methods with the cable laying device and their driving and movement methods. Regarding connection methods, most employ fixed structures, which restricts the necessary freedom of movement for the cable laying device. In actual cable laying, due to the complex and diverse seabed topography, including obstacles such as trenches, ridges, and reefs, and the constantly changing sea conditions such as the impact of waves and currents, fixed-connection cable laying devices cannot flexibly adjust their position and attitude. This makes it difficult to accurately lay the cable according to the planned path, potentially leading to deviations in cable placement, affecting its subsequent normal use, and also causing damage to the cable due to collisions or friction with obstacles, increasing project costs and construction risks.

[0004] In response to the aforementioned existing technologies, and to address the issue that submarine cable laying devices cannot flexibly adjust their position and orientation, the applicant has designed a suspension fixture for a submarine cable laying device. Utility Model Content

[0030] This application discloses a suspension fixture for a submarine cable laying device.

[0031] A suspension fixture for a submarine cable laying device, referring to Figure 1 It includes a frame 1, multiple slings 2 for fixed connection with slings, and a hydraulic cylinder 3; the slings 2 are fixedly installed on the top of the frame 1, and the end of the frame 1 away from the slings 2 is connected to the submarine cable laying device by a hinge; one end of the hydraulic cylinder 3 is rotatably installed on the frame 1, and the other end of the hydraulic cylinder 3 is rotatably installed on the submarine cable laying device.

[0032] In use, firstly, the slings are fixedly connected to the multiple lifting plates 2 at the top of the frame 1, and the slings are securely installed on the lifting plates 2 using corresponding connectors. Then, using lifting equipment, the suspension fixture is lifted and moved to the designated position above the submarine cable laying device via the slings. Next, the end of the frame 1 furthest from the lifting plates 2 is connected to the submarine cable laying device via a hinge. The hinge connection provides the submarine cable laying device with a certain degree of rotational freedom, allowing the device to flexibly adjust its angle within a certain range.

[0033] When it is necessary to adjust the horizontal position of the submarine cable laying device, the extension and retraction of hydraulic cylinder 3 will cause the submarine cable laying device to move horizontally. The action of hydraulic cylinder 3 will cause the submarine cable laying device to rotate around the hinge point. By controlling hydraulic cylinder 3, the submarine cable laying device can be adjusted to a suitable tilt angle to ensure that the submarine cable laying device can be accurately laid to the target position.

[0034] Reference Figure 2 and Figure 3 Specifically, the frame 1 includes a circular block 11 and a triangular plate 12. The triangular plate 12 is welded and fixed along the central axis of the circular block 11, making the whole structure conical. One end of the hydraulic cylinder 3 is rotatably mounted on one side of the triangular plate 12, and a reinforcing plate 4 is welded and fixed on the other side of the triangular plate 12. The reinforcing plate 4 is triangular. This connection method enables the hydraulic cylinder 3 to effectively transmit power to the frame 1, thereby driving the submarine cable laying device to adjust its position and angle. The triangular reinforcing plate 4 can more evenly distribute stress when subjected to external force, reduce local stress concentration, and thus enhance the stability and deformation resistance of the overall structure.

[0035] Furthermore, the suspension plates 2 are arranged parallel to the side of the circular block 11 away from the triangular plate 12 and are welded and fixed to the circular block 11. The suspension plates 2 have connection holes 5 for fixed connection with the sling. This design allows the tension of the sling to be evenly distributed across each suspension plate 2. Multiple suspension plates 2 share the tension of the sling, avoiding excessive stress on a single suspension plate 2.

[0036] Furthermore, multiple reinforcing blocks 6 are welded and installed on the circular block. The reinforcing blocks 6 are triangular and are located on both sides of the suspension plate 2, with both sides of the suspension plate 2 welded and fixed to the reinforcing blocks 6. The reinforcing blocks 6 can distribute the tension applied to the suspension plate 2 by the sling more evenly. When the sling is connected to the suspension plate 2 through the connector and tension is applied, the reinforcing blocks 6 can distribute the tension to a larger area, avoiding excessive local stress on the suspension plate 2, thereby preventing deformation, tearing, or other damage to the suspension plate 2.

[0037] Furthermore, a fixing block 7 is provided at the end of the triangular plate 12, and a fixing hole 8 is provided through the fixing block 7 for hinge connection with the submarine cable laying device. The fixing hole 8 on the fixing block 7 provides a precise positioning reference for hinge connection with the submarine cable laying device. The hinge connection with the submarine cable laying device through the fixing hole 8 provides the submarine cable laying device with rotational freedom, allowing it to flexibly adjust the angle within a certain range.

[0038] The implementation principle of the application embodiment is as follows: Multiple lifting plates 2 are arranged in parallel and welded to the side of the circular block 11 of the frame 1 away from the triangular plate 12. The lifting plates 2 are provided with connection holes 5. The sling and the lifting plate 2 are firmly connected by corresponding connectors. Since multiple lifting plates 2 share the tension of the sling, and the reinforcing blocks 6 on both sides of the lifting plates 2 can distribute the tension more evenly, it avoids excessive stress on a single lifting plate 2 and ensures the reliability of the connection. Using lifting equipment, the suspended fixture is lifted and moved to the designated position above the submarine cable laying device by the sling. In this process, the structure of the frame 1 can ensure the stability of the fixture and withstand the tension during the lifting process. The end of the frame 1 away from the lifting plate 2 is connected to the submarine cable laying device by a hinge. Specifically, the end of the triangular plate 12 is provided with a fixing block 7, and the fixing hole 8 on the fixing block 7 provides a precise positioning reference for hinge connection with the submarine cable laying device. When it is necessary to adjust the tilt angle of the submarine cable laying device, the extension and retraction speed of the hydraulic cylinder 3 can be controlled to adjust the device to a suitable tilt angle, ensuring that the submarine cable can be accurately laid to the target location. For example, when laying the submarine cable on a slope or in a gully area of ​​the seabed, precise angle adjustment can be achieved by controlling the hydraulic cylinder 3.

[0039] After completing the connection of the tooling and the cable laying device, and adjusting their position and angle, the cable laying operation begins. The lifting equipment slowly lowers the suspended tooling and cable laying device, releasing the cable from the device. As the tooling moves and is adjusted, the cable is gradually laid to the designated position. During the laying process, the state of hydraulic cylinder 3 is adjusted according to the actual situation to ensure the quality and smooth progress of the cable laying.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
