Description

Technical Field

[0001] The present invention belongs to the field of ship equipment design, and relates to the design, layout and installation of a cable bracket that can adapt to height difference changes. Background Art

[0002] Generally, a shore power box is arranged at the stern of a super-large trailing suction hopper dredger, and a shore power winch is required to be arranged near the shore power box for releasing and retrieving the shore power cable. At the same time, deck cabins such as a CO2 room, a chimney, an equipment room, a workroom, a warehouse, etc., as well as deck equipment such as an anchor winch, mooring fittings, a crane, etc. are arranged on the main deck at the stern of the super-large trailing suction hopper dredger. There is no space on the main deck at the stern to arrange the shore power winch. In order to make full use of the space at the stern of the main deck and at the same time arrange the shore power winch near the shore power box, a cable reel platform with a height of about 3.3 m is built in this area for arranging the shore power winch and its cable bracket. The cable reel is arranged near the hull center line and faces the side. After the dredger docks at the wharf, the cable comes out of the shore power winch, passes through the cable reel platform and the main deck, and finally connects to the shore power box at the wharf. During the process of the dredger docking at the wharf, different drafts will cause the height difference between the shore power winch and the shore power box at the wharf to change; in addition, different wharves where the dredger docks also have differences in the height difference between the shore power winch and the shore power box at the wharf. The change in the height difference between the shore power winch and the shore power box at the wharf will cause the cable to be slack or taut. When the cable is in a slack state, it is easy to rub against the hull structure or other equipment, and when the cable is in a taut state, it is easy to cause it to bear too much tension. Therefore, whether the cable is in a slack state or a taut state, it will cause damage to it, reduce its service life, affect the use effect, and reduce the operation efficiency and safety.

[0003] In order to meet the cable support and guiding requirements under different height differences between the shore power winch and the shore power box at the wharf, so that the cable can avoid being too slack or too taut under different height differences, protect the cable from damage, extend the service life of the cable, improve the operation efficiency and safety, there is an urgent need to provide a new solution and tool with good social and economic benefits.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0034] The present invention discloses a cable bracket device capable of adapting to height difference changes, which is mainly used for ultra-large trailing suction hopper dredgers, and of course is also applicable to other engineering ships or transport ships with the same requirements

[0035] AsFigure 1 and Figure 2 As shown in Figure 2 , the cable bracket is arranged on the cable outlet path of the shore power winch 8. It is mainly composed of a fairlead 1, an extended fairlead 2, a pulley 3, a tail-end guide rail supporting wheel 4, a middle-section guide rail supporting wheel 5, a head-end guide rail supporting wheel 6, a bracket base 7, etc. Through the mutual cooperation of each component, the effective support and guidance of the cable are realized. By setting the fairleads 1 on the ship's side with different heights and lengths and reasonably adjusting their rotation angles, the usage requirements under different height differences can be met.

[0036] As Figure 3 and Figure 4 As shown in Figure 3 and Figure 4 , the structures and functions of the fairlead 1 and the extended fairlead 2 are similar. They include a structural frame I 9, a roller I 10, a rotating shaft 11, a rotation adjustment mechanism 12, a handwheel 13, and a mounting base 14. The structural frame I 9 is composed of two metal side plates. The roller I 10 is connected between the two side plates through a core shaft. The roller I 10 is used for the support and guidance of the cable to ensure that the cable can pass smoothly. The tail of the structural frame I 9 is connected to the mounting base 14 through the rotating shaft 11 and can rotate around the rotating shaft 11. The rotation adjustment mechanism 12 is set on the mounting base 14. The operator can adjust the rotation angle of the structural frame I 9 through the handwheel 13, thereby changing the spatial position of the fairlead 1. The mounting base 14 is fixed to the ship's side deck by bolts, which is convenient for installation and disassembly. By setting the fairleads 1 on the ship's side with different heights and lengths and reasonably adjusting their rotation angles, the support and guidance requirements of the cable under different height differences between the shore power winch 8 and the shore power box at the dock can be adapted, so that the cable can avoid being too loose or too tight under different height differences, effectively protecting the cable from damage and extending its service life.

[0037] As Figure 5 , Figure 6 and Figure 7As shown in the figure, the guide rail carrier wheels are divided into the tail-end guide rail carrier wheel 4, the middle-section guide rail carrier wheel 5, and the head-end guide rail carrier wheel 6. Their structures are basically the same and all include a base 15, a trolley track 16, a roller 17, an end baffle 18, and an end sleeve 19. The base 15 is composed of two angle steels, and the roller 17 is connected between the angle steels through a core shaft. The roller 17 is used for the support and guidance of the cable to ensure that the cable can slide smoothly on the carrier wheel. A steel pipe is welded above the angle steel as the trolley track 16, and the trolley track 16 is used for the support and guidance of the trolley 3, enabling the trolley 3 to move stably along the track. An end baffle 18 is provided at the end of the trolley track 16 to limit the movement range of the trolley 3 and prevent the trolley 3 from derailing. An end sleeve 19 is also provided at the end of the trolley track 16 for connecting each section of the guide rail to achieve modular connection of the guide rail carrier wheels. Each section of the guide rail carrier wheel is a fabricated integral module, and the integral modules are connected and disassembled through the end sleeves on the trolley track 16, greatly simplifying the installation process. At the same time, by conveniently connecting and disassembling each section of the guide rail carrier wheel, the length of the cable support can be flexibly adjusted, enabling it to be applicable to more application scenarios and having good social and economic benefits.

[0038] As Figure 8 shown in the figure, the trolley 3 includes a structural frame 20, a guiding device 21, a roller 22, and a pulley 23. The structural frame 20 is composed of two square tubes, and the roller 22 is connected between the square tubes through a core shaft. The roller 22 is used for the support and guidance of the cable to ensure that the cable can move smoothly on the trolley 3. A guiding device 21 is provided at the end of the square tube. A round hole is opened in the middle of the guiding device 21 for nesting the trolley track 16, enabling the trolley 3 to move along the trolley track 16 and realizing flexible guidance of the cable. The pulley 23 is installed below the structural frame 20 and is supported by the trolley track 16 to further ensure the stable movement of the trolley 3 on the track. The trolley 3 plays an important role in supporting and guiding in the cable support, and cooperates with the guide rail carrier wheel and the cable guiding frame 1 to jointly achieve smooth transmission and effective protection of the cable under different height differences.

[0039] The installation of the cable support is relatively simple. The installation base 14 of the cable guiding frame 1 is bolted to the ship's side deck, with firm connection and convenient disassembly. During use, the operator can adjust the rotation angle of the cable guiding frame 1 by turning the handwheel 13, and adjust the length, height, and rotation angle of the cable guiding frame 1 according to the actual height difference between the shore power winch 8 and the dock shore power box, so as to meet the requirements of cable support and guidance under different height differences. The guide rail carrier wheel adopts a modular design. Each section of the guide rail support includes a trolley track 16 of a certain length, several bases 15, and rollers, forming an integral module. The integral modules are connected and disassembled through the sleeves at the ends of the trolley track 16, simplifying the installation process. At the same time, the flexible adjustment of the guide rail length can greatly expand the application range of the cable support and meet the use requirements under different working conditions.

[0040] The cable bracket of the present invention has various advantages and benefits. Firstly, by providing side fairleads 1 with different heights and lengths and reasonably adjusting their angles, the cable support and guiding requirements between the shore power winch 8 and the dock shore power box with different height differences can be met, enabling the cable to avoid being too slack or too taut at different height differences, effectively protecting the cable from damage, extending the service life of the cable, and being easy to operate. Secondly, the fairlead 1 located on the side can conveniently adjust its rotation angle through the handwheel 13, with simple operation and good adaptability, and can be adapted to local conditions to match the cable support and guiding requirements at different height differences. Moreover, the cable bracket is designed and manufactured using angle steel, steel pipes and other common profiles, with a simple structure and convenient production, reducing the manufacturing cost. In addition, the cable bracket can effectively reduce manual cable guiding operations, improving the work efficiency and safety of the operators. At the same time, with modular design, the installation process is simplified, and the flexible adjustment of the guide rail length can greatly expand the application range of the cable bracket. The cable bracket is located on the raised deck, does not occupy the main deck space, makes full use of the space at the stern, and does not require ordering equipment from professional manufacturers. The shipyard can make it according to the drawings, which not only saves costs but also improves the progress, having good social and economic benefits.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
