Description

Technical Field

[0001] This invention relates to a marine cable harness fixing and docking device, which belongs to the technical field of marine cable harness fixing. Background Technology

[0002] Existing cable bundle splicing devices are mostly designed for single or bundled submarine cables with small cross-sections, which are less affected by waves, experience less undulation and swaying, and require almost no further disassembly or movement after splicing. While common cable bundle cross-sections are circular, with increasing current demands and easier coiling and storage, large rectangular cable bundles have emerged. These large rectangular cable bundles require more frequent splicing and disassembly. Cable bundles need to be suspended underwater, subject to wave influence, exhibiting significant undulation and swaying. Furthermore, the marine environment necessitates frequent splicing and disassembly of offshore cables, and the rapid tidal changes impose time constraints on operations. Therefore, for large cable bundles splicing at sea, securing the ends of these large rectangular cable bundles to suitable working positions on marine structures has become a key problem to be solved. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a marine cable bundle fixing and docking device, which, with the assistance of a crane to lift and lower the cable bundle, enables the clamping, positioning, and fine-tuning of large square cable bundles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a marine cable bundle fixing and docking device, comprising a cable bundle fixing module installed on a marine structure, the cable bundle fixing module including a fixing trolley and a cable bundle guiding unit, wherein the fixing trolley's fixing trolley base plate is fixed to the marine structure, and two fixing trolley side plates are provided on the fixing trolley base plate, with a gap between them for the cable bundle to pass through; a fixing trolley inner support plate for supporting the cable bundle is provided between the two fixing trolley side plates; and a fixing trolley clamping bolt group for clamping the cable bundle is provided on the fixing trolley side plates;

[0005] In the cable harness guiding unit, the guide base is fixed to the marine structure. Two guide side plates are provided on the guide base, and dovetail plates are respectively provided on the top of the two guide side plates. The two dovetail plates form a dovetail groove symmetrically inward. A vertical idler roller for guiding the cable harness is provided between the bottom plate of the dovetail groove and the guide base. A bottom idler roller for supporting and guiding the cable harness is provided on the guide base through the idler roller base. When the cable harness passes through the cable harness guiding unit, both the vertical idler roller and the bottom idler roller can rotate around the connecting shaft.

[0006] The top of the fixed vehicle side panel is provided with a fixed vehicle cover plate and a fixed vehicle lock buckle.

[0007] The outer side of the guide side plate is provided with a reinforcing guide rib.

[0008] The beneficial effects of this invention are:

[0009] This invention relates to a cable bundle guiding unit for large square cable bundles. It provides a certain degree of restraint for the submarine cable, preventing it from swaying laterally on the marine structure. Simultaneously, a certain sway gap is maintained between the vertical rollers to prevent the device from clamping or bending the cable. The cable bundle guiding unit is an open-type support structure, including four vertical rollers and one bottom roller. Given the large size and weight of the submarine cable bundle, this unit guides and supports the cable bundle, enabling its smooth movement.

[0010] The position of the fixed trolley is fixed and does not slide; the operation of the fixed trolley cover and clamping mechanism is quick and easy: the trolley cover is locked with a snap-on lock, and the clamping mechanism uses an array of bolts, which are easy to adjust and have a long service life and are reliable.

The following embodiments are merely descriptive and not limiting, and should not be construed as limiting the scope of protection of the present invention. In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In the description of the present invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0017] This invention relates to the field of machinery and provides a device capable of fixing cable ends and adjusting their position to facilitate wiring. The device is entirely manually operated and includes operations for fixing the cable end and fine-tuning its position. The device consists of two docking modules, with selectable options for whether the modules have fine-tuning capabilities. The module with only a fixing function is called a cable harness fixing module, while the module with fine-tuning capabilities is called a cable harness fine-tuning module.

[0018] Figure 1 A marine cable bundle fixing and docking device is shown, in which a cable bundle fixing module 1 is installed on the marine structure 1. The cable bundle fixing module includes a fixing trolley 3 and a cable bundle guiding unit 4. Both the fixing trolley 3 and the cable bundle guiding unit 4 are fixed to the surface of the marine structure 1 by bottom bolts. The position of the fixing trolley 3 in the fixing module is fixed and does not slide. The cable bundle guiding unit 4 is an open-type support structure, including four vertical rollers and one bottom roller, which guides and supports the cable bundle and enables smooth movement of the cable bundle.

[0019] Figure 2The diagram shows the structure of the fixed trolley 3, where a fixed trolley base plate 31 is fixed to the marine structure 1. Two fixed trolley side plates 33 are mounted on the fixed trolley base plate 31, with a gap between them for the cable bundle to pass through. A fixed trolley clamping bolt assembly 34 for clamping the cable bundle is mounted on the fixed trolley side plates 33. A fixed trolley cover plate 35 and a fixed trolley latch 36 are mounted on the top of the fixed trolley side plates 33. An inner fixed trolley support plate 32 for supporting the cable bundle is located between the two fixed trolley side plates 33. The fixed trolley 3 has a hinged cover plate on its upper part. Placing the cable bundle within the frame formed by the side plates and cover plate prevents the cable bundle from detaching. An array of bolts is installed on the cover plate, side plates, and base plate of the trolley. This serves two purposes: firstly, it prevents the cable bundle from slipping out of the trolley; secondly, the clamping bolts allow for fine-tuning of the cable bundle's posture, facilitating cable bundle docking.

[0020] Figure 3 The diagram illustrates the structure of the cable harness guiding unit 4, where a guide base 41 is fixed to the marine structure 1. Two guide side plates 42 are mounted on the guide base 41, with dovetail plates 44 atop each. The two dovetail plates 44 symmetrically form dovetail grooves. A vertical roller 45 is positioned between the dovetail groove bottom plate 48 and the guide base 41. A bottom roller 47 is mounted on the guide base 41 via roller base 46. Reinforcing guide ribs 43 are provided on the outer side of the guide side plates 42. The upper opening is designed as a dovetail groove for easy cable harness insertion.

[0021] When using the above technical solution, the operation process is divided into fixing the cable bundle end and removing the cable bundle end.

[0022] The cable harness fixing module secures the cable harness end:

[0023] 1. When the cable bundle end enters the fixing module 1, the cable bundle is transported by a crane, and the cable bundle end is placed into the cable bundle guiding unit 4 and the fixing trolley 3 along the opening dovetail groove of the cable bundle guiding unit 4, and the connection between the crane and the cable bundle is released.

[0024] 2. Manually cover the fixed carriage cover plate 35 of the fixed carriage 3, lock the latch-type fixed carriage buckle 36, and lock the fixed carriage clamping bolt group 34 to fix the cable bundle on the fixed carriage 3.

[0025] Remove the cable bundle end:

[0026] 1. Connect the crane to the cable bundle end;

[0027] 2. Manually open the latch-type lock on the cover of the fixed trolley 3;

[0028] 3. The crane lifts the cable bundle, and the cable bundle is separated from the fixed docking module.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
