Description

Technical Field

[0001] This utility model relates to the field of cable installation auxiliary technology, specifically a composite cable installation guide tool suitable for horizontal construction of conduit frames. Background Technology

[0002] In existing tensioned impressed current cathodic protection technology, corrosion detection and protection of offshore platforms are generally achieved through composite cables integrating a reference electrode and an auxiliary anode. These composite cables are typically tensioned and installed inside the platform. For horizontally constructed jackets, the composite cables cannot be installed vertically. They must be installed horizontally according to the jacket's construction posture, and then transition to a vertical service position after the jacket is launched and aligned.

[0003] In the prior art, when installing composite cables on a horizontal conduit frame, a cable roller is installed at the composite cable installation position at the top of the conduit frame. A sliding cable is set on the conduit frame corresponding to the path of the composite cable between the top and bottom of the conduit frame, and the sliding cable is tensioned at the bottom of the conduit frame. The traction rope is pulled from the top of the conduit frame to the bottom of the conduit frame along with the wire rope sliding cable. The end of the composite cable is connected to the beginning of the traction rope. The traction rope is retrieved at the bottom of the conduit frame, and the composite cable is released simultaneously from the cable roller. A slip ring is installed on the composite cable and hung on the sliding cable. The traction rope is retrieved from the bottom of the conduit frame, and the composite cable wound on the cable roller is released at the same time. The composite cable is suspended below the wire rope sliding cable through multiple slip rings. During the process of pulling the composite cable from the ground to the platform for transportation and fixing, the composite cable will be bent. If the bending radius is too small, it will cause damage to the auxiliary anode and the steel cable. Therefore, protective measures and bending protection for the reverse composite cable are required.

[0004] The commonly used protection method is to increase the bending radius of composite cables by installing extra-large guide wheels. However, extra-large guide wheels are large in size, which makes installation difficult and costly on site. In addition, the bending angle of extra-large guide wheels is limited and cannot adapt to composite cables with different bending degrees. Therefore, the applicability is low and it is difficult to meet the usage requirements. To address this, a composite cable installation guide fixture suitable for horizontally constructed conduit frames is proposed. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] This application provides a composite cable installation guide fixture suitable for horizontal conduit construction. It solves the problems of large space occupation, inconvenient assembly, and low adaptability associated with using oversized guide wheels for bending protection during composite cable transport in horizontal conduit construction. The fixture replaces the traditional oversized guide wheels with a load-bearing guide structure featuring an arc-shaped guide surface 111. During installation, by adjusting the tilt angle of the transverse support frame 2 or the height difference of the vertical support frame 2, the arc-shaped guide surface 111 can meet the bending protection requirements of cables of different specifications. This better protects the composite cable and its related accessories, preventing excessive bending and damage to the composite cable during laying, and improving the convenience and safety of composite cable installation.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] This utility model discloses a composite cable installation guide fixture suitable for horizontal construction of conduit frames.

[0031] Example 1, according to Appendix Figure 1 As shown, it includes a load-bearing guide structure, a support frame 2, a protective frame 3, and an operating platform.

[0032] The load-bearing guide structure has an arc-shaped guide surface 111 for carrying the composite cable, and the composite cable and the arc-shaped guide surface 111 are slidably connected.

[0033] The support frame 2 is used to support the load-bearing guide structure. The support frame 2 has an arc-shaped support part that is adapted to the arc-shaped guide surface 111 and a connecting part that can be connected to both ends of the arc-shaped guide surface 111 in the length direction. The connecting part is laterally arranged across the opening side of the arc-shaped guide surface 111.

[0034] The operating platform is connected to the support frame 2 and is used to support the support frame 2.

[0035] When laying composite cables, a temporary operating platform is erected on the guide frame. The support frame 2 and the load-bearing guide structure are assembled and installed on the operating platform. One end of the composite cable to be laid is connected to the cable drum, and the other end rests on the load-bearing guide structure and extends along the arc-shaped guide surface 111. This way, during the laying process, the load-bearing guide structure can support the composite cable and adapt to its bending, preventing damage to the composite cable due to excessive bending. After laying is completed, the installation guide fixture can be recycled by dismantling the temporary operating platform, allowing it to be reused multiple times.

[0036] In a specific embodiment, the support frame 2 consists of two parallel H-beams 21 and two arc-shaped square steels 22. The two ends of the square steels 22 are welded to the corresponding ends of the H-beams 21. The curvature of the square steels 22 is equal to the curvature of the arc-shaped guide surface 111. The distance between the two H-beams 21 is equal to the width of the orthographic projection of the arc-shaped guide surface 111. Reinforcing rods 23 are fixedly installed in the middle of each of the two H-beams 21. The reinforcing rods 23 are perpendicular to the H-beams 21, and the end of the reinforcing rod 23 furthest from the H-beam 21 is fixedly connected to the middle of the arc-shaped square steel 22, which improves the support strength of the support frame 2 for the load-bearing guide structure. The support frame 2 is made of aluminum alloy composite material and serves as the main fixing component of the entire device, stabilizing the structure. Its arched design allows it to withstand greater load-bearing capacity and is less prone to deformation.

[0037] In a specific embodiment, the load-bearing guide structure includes a guide belt 11, a drive roller assembly 12, a tension roller, and a transmission structure 13. The drive roller assembly 12 includes a driving roller 121 and several driven rollers 122. The driving roller 121 and one driven roller 122 are respectively installed at both ends of the square steel 22 along its length, and the remaining driven rollers 122 are evenly distributed between the two square steels 22. The tension roller is installed between two reinforcing rods 23, and the tension roller is installed on the side closer to the square steel 22. The guide belt 11 is wrapped around the drive roller assembly 12 and the tension roller. The guide belt 11 is ring-shaped. Under the action of the transmission roller group 12, the surface where the guide belt 11 contacts the composite cable is an arc-shaped guide surface 111. The guide belt 11 is soft and has high toughness, which can support the composite cable and prevent the composite cable from sagging due to its own weight, thus avoiding internal damage to the composite cable. It also protects the cable body and auxiliary anode components. The tension roller tensions the guide belt 11, preventing slippage between the guide belt 11 and the roller due to excessive looseness, and extending its service life.

[0038] The transmission structure 13 is used to drive the guide belt 11 to rotate periodically. The direction of movement of the guide belt 11 is the same as the direction of movement of the composite cable. The moving guide belt 11 can apply driving force to the composite cable, making the entire installation process smoother.

[0039] In a specific embodiment, the transmission structure 13 includes a motor 131, a main pulley 132, a driven pulley 133, and a transmission belt 134. The main pulley 132 is mounted on the output end of the motor 131. The driven pulley 133 is connected to the drive roller 121. The transmission belt 134 is wound around the main pulley 132 and the driven pulley 133. The motor 131 is mounted on the support frame 2. When the motor 131 is started, it outputs torque, which is transmitted through the transmission belt 134 and the pulley assembly. This force ultimately acts on the drive roller 121, generating a driving force that drives the guide belt 11. The speed of the motor 131 can be adjusted according to the actual installation situation to ensure synchronization. Due to the control characteristics of the motor 131, a controller can be connected to the entire composite cable installation system to control the operation of the system uniformly and avoid human error.

[0040] In a specific embodiment, the ratio of the diameter of the arc-shaped guide surface 111 to the diameter of the composite cable to be laid is ≥10, and the central angle corresponding to the arc-shaped guide surface 111 is >90°. In this embodiment, the central angle corresponding to the arc-shaped guide surface 111 is 96°.

[0041] In a specific embodiment, the angle between the composite cable before passing through the arc-shaped guide surface 111 and the composite cable after passing through the arc-shaped guide surface 111 is ≥90°. In this embodiment, the angle between the composite cable before passing through the arc-shaped guide surface 111 and the composite cable after passing through the arc-shaped guide surface 111 is 114°38′.

[0042] In a specific embodiment, the protective frame 3 is connected to the support frame 2 and is used to limit the displacement of the composite cable in the width direction of the arc-shaped guide surface 111, preventing the composite cable from detaching from the arc-shaped guide surface 111 from both sides.

[0043] A protective plate 31 is installed on the inner side of the protective frame 3. The protective plate 31 is made of acrylic material. Acrylic material has good light transmittance, which limits the composite cable while not obstructing the view, making it convenient to observe the cable transportation status.

[0044] Example 2 differs from Example 1 only in that the support frame 2 consists of four vertically arranged I-beams 21 and two arc-shaped square steels 22. The four I-beams 21 are respectively arranged at the corners of the arc-shaped guide surface 111. The upper ends of the I-beams 21 and the arc-shaped square steels 22 are fixedly connected. The two I-beams 21 located on the same side of the arc-shaped guide surface 111 have the same height. The four I-beams 21 are divided into two groups. The two groups of I-beams 21 are respectively arranged on both sides of the length direction of the arc-shaped guide surface 111. The heights of the two groups of I-beams 21 are different.

[0045] In a specific embodiment, the tilt angle of the support frame 2 is determined based on the height difference between the two sets of I-beams 21 and the distance between the two sets of I-beams 21. This tilt angle is mainly determined based on the actual installation conditions on site and can be adjusted accordingly based on the position of auxiliary parts such as winches and pulleys on site to ensure that the included angle between the composite cable before passing through the arc-shaped guide surface 111 and the composite cable after passing through the arc-shaped guide surface 111 is ≥90°.

[0046] The method for laying composite cables using the composite cable installation guide fixture of this application is as follows:

[0047] Combination Figure 1 and Figure 2 As shown, the composite cable needs to run through ends A and B of the conduit frame along its length. A sliding steel wire rope is pre-installed on the conduit frame, with both ends fixed to the ground and tensioned using traction winches. A temporary operating platform is built on the conduit frame. The support frame 2 and the load-bearing guide structure are assembled and installed on the operating platform. The composite cable is wound around a roller and placed on the ground on side A of the conduit frame. It is then pulled to the correct position by a second steel wire rope, ensuring the composite cable is completely on the tooling conveyor belt. Formal installation can then begin. Once the composite cable reaches the predetermined tension, the steel wire rope, guide tooling, and other auxiliary equipment are disassembled, completing the cable installation process. The device has a simple and compact overall structure, occupies little space, has a low failure rate, high reliability, and can adapt to complex environments.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
