Description

Technical Field

[0001] The invention belongs to the technical field of ship outfitting, and particularly relates to a cable bracket. Background Art

[0002] In the power system of a ship, cables are densely intertwined. As an important device for supporting and fixing cables, the performance and quality of the cable bracket are crucial for the operation of the ship's power system. Traditional ship cable brackets are mostly welded with heavy steel, which is not only heavy but also cumbersome to install and difficult to maintain. At the same time, during the operation of the ship, due to the long-term power supply, vibration and working environment, the cable bracket is prone to corrosion and failure. Moreover, the traditional cable bracket is often closely connected to the hull structure, with narrow operating space and difficult to maintain and replace. In addition, when the ship is sailing at sea, it is affected by the impact of waves, the swaying of the hull and mechanical operation, etc., resulting in the cable bracket being prone to breakage, loosening, displacement, etc. during use, which not only affects the ship operation but also may cause potential safety hazards. To sum up, it is of great significance to develop a ship cable bracket that is light, easy to maintain and replace, and has good stability and anti-vibration performance for improving the reliability of the ship's power system and the ship operation performance.

Detailed implementation mode

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] As Figures 1 - 11 shown, a marine cable bracket includes multiple groups of bracket bodies 3, multiple hoop bars 13 and multiple bracket hanging baskets. Each group of the bracket bodies 3 includes two bracket bodies 3. Each of the hoop bars 13 is respectively fixed in the middle of a T - beam / bulkhead 2. The two bracket bodies 3 in each group are mirror - symmetrically arranged between two adjacent hoop bars 13. The relative ends of two adjacent groups of bracket bodies 3 extend into the same hoop bar 13 and are connected through a fastening system. The upper end of the bracket hanging basket is fixedly connected to the reverse side of the deck 1. The adjacent ends of the two bracket bodies 3 in each group are respectively placed on a bracket hanging basket. One end of the cable lashing rope 11 passes through the bracket lashing hole 10 and is connected to the lashing rope buckle 2310 to fix the cable 26.

[0028] It can be understood that the bracket body 3 is not in direct contact with the hull. It is indirectly connected to the hull through the bracket hanging basket to avoid permanent damage to the bracket body 3 caused by the vibration and deformation of the hull, eliminating the hidden danger of structural fatigue nodes. That is to say, the bracket body 3 in this embodiment does not participate in the strength and is not affected by the deformation / vibration / twist of the ship. It does not have the fatigue property. Therefore, only the weight of the cable needs to be considered, and the plate thickness of the bracket body 3 can be minimized and the lightening holes 9 can be increased to achieve the purpose of a light - type cable bracket.

[0029] In this embodiment, the fastening system includes multiple groups of fastening plates 20 in pairs. One end of two fastening plates 20 in each group is fixedly connected to the end faces of two bracket bodies 3 respectively. The extending direction of the fastening plates 20 is parallel to the length direction of the bracket body 3. The adjacent ends of the two fastening plates 20 are arranged in an up-and-down overlapping manner; the fastening plates 20 are of a rectangular ring structure, and sawteeth are provided on one side of the inner ring side surface along the length direction of the bracket body 3. The sawteeth on the two fastening plates 20 arranged in an up-and-down overlapping manner are located on the opposite side surfaces, and the two fastening plates 20 are coupled by a fastening gear 14 located within their overlapping rings; arrayed round holes are oppositely provided on both side edges in the length direction of the fastening plates 20. When in a fixed position, both ends of a number of limiters 19 are inserted into the round holes on both opposite sides.

[0030] When the opposite ends of two bracket bodies 3 are connected, the two fastening plates 20 are arranged in an up-and-down overlapping manner, the fastening gear 14 is inserted, the fastening handle 15 is inserted into the groove above the fastening gear 14 for coupling, the fastening gear 14 is rotated through the fastening handle 15 to drive the two fastening plates 20 to a proper position until the openings on both sides overlap, a number of limiters 19 are inserted into the round holes, and the fastening handle 15 is removed.

[0031] It can be understood that since each section of the bracket body 3 is independent, only the ends of the 2 sections of the bracket body 3 within the hoop reinforcement 13 are connected by the fastening system. The fastening system mainly relies on the gear to adjust and tighten the 2 sections of the brackets (the fastening handle 15 is mainly for saving effort). After adjustment, an appropriate amount of limiters 19 are placed (the holes on both sides of the two lower fastening plates 20 need to be aligned to insert the limiters 19), and the fastening handle 15 is removed; when replacement is needed, the limiters 19 are taken out, then the gear is removed, and the other end of the bracket body 3 is disassembled and separated from the bracket hanging basket, and then a new bracket body 3 can be replaced.

[0032] Further, a shock-absorbing sheet 8 is provided between the lower end face of one end of the bracket body 3 within the hoop reinforcement 13 and the inner bottom surface of the hoop reinforcement 13. The thickness t1 of the shock-absorbing sheet 8 placed below the bracket body 3 above the fastening plate 20 is greater than the thickness t2 of the shock-absorbing sheet 8 below the bracket body 3 above the fastening plate 20.

[0033] It can be understood that the setting of the shock-absorbing sheet 8 can further reduce the influence of the vibration from the hull on the bracket body 3.

[0034] In this embodiment, the bracket hanging basket includes a support plate 4. On both sides of the support plate 4 parallel to the length direction of the bracket body 3, two suspension rods 5 are symmetrically arranged. The lower part of the suspension rod 5 is provided with an external thread. The lower end of the suspension rod 5 passes through the support plate 4 and is fixedly connected through a nut 6. The upper end of the suspension rod 5 is fixedly connected to a backing plate 16 or a bulb flat bar / flat iron 17 fixed to the reverse side of the deck 1. Between the nut 6 and the lower end face of the support plate 4, a shock-absorbing sheet 8 and a gasket 7 are sequentially arranged from top to bottom.

[0035] The bracket body 3 includes a bottom plate 31 and two side plates 32 located on both sides of the bottom plate 31 in the length direction. Two circular holes are symmetrically arranged at one end of the bottom plate 31 far from the hoop bar 13 relative to the center line. One end of the bracket body 3 is placed on the support plate 4, and the bottom plate 31 is connected through a bolt 28 that sequentially passes through the support plate 4 and the circular hole; the bracket lashing holes 10 are oppositely arranged on the two side plates 32.

[0036] The upper surface of the shock-absorbing sheet 8 is adhered to the lower surface of the bottom plate 31, and the lower surface of the shock-absorbing sheet 8 is in contact with the inner surface of the hoop bar 13. Lightening holes 9 and hook holes 27 are evenly distributed on the bottom plate 31. Lightening holes 9 and bracket lashing holes 10 are evenly distributed on the two side plates 32. The ends of the side plates 32 are beveled; a hook 25 passes through the hook hole 27. Rotate the hook 25 to the target position, and a working tow line and tools can be added to the end of the hook 25. The addition of the hook 25 increases the usage scenarios and functions.

[0037] Since the bracket body 3 belongs to a light bracket, more lightening holes 9 can be opened on both the side plates 32 and the bottom plate 31 of the bracket body 3. The shape and position of the lightening holes 9 can be set according to needs. Taking the description of the present invention as an example, long strip holes are opened at the bottom to fit the hook 25. Because the space in the ship engine room is narrow and mechanical equipment is densely arranged, for temporary maintenance during operation, tools and cables can be hung on the hook 25, which is flexibly applicable to various changes.

[0038] In this embodiment, the bracket body 3 is a two-section structure arranged sequentially along the length direction. The bottom plates 31 of the front and rear sections are rotatably connected through a hinge 22, and the two side plates 32 at the front and rear ends are connected through a buckle 23 and a bolt 24; during maintenance, open the buckle 23, cut the cable lashing rope 11 of the maintenance section, and remove the hanging basket.

[0039] It can be understood that by adopting a segmented bracket structure and placing 2 sections of independent brackets between every 2 T-beams / bulkheads, the bracket body 3 can achieve precise positioning and opening for maintenance without large-area disassembly. The two-section bracket structure is connected through a hinge 22 and a buckle 23. During maintenance, open the buckle 23 and remove the bracket hanging basket at the other end at the same time, and one end of one section of the bracket structure can be tilted downward. The detachable buckle 23 and the bracket hanging basket cooperate to open the cable bracket for maintenance work.

[0040] Further, one end of the cable binding rope 11 is a riveted circle, and the other end is serrated and coupled with the serrations inside the binding rope buckle 12. The serrated end of the cable binding rope 11 passes through the bracket binding hole 10 and is coupled with the binding rope buckle 12.

[0041] Further, on the side of the outermost bracket body 3 in a row of cable brackets close to the hoop rib 13, it is connected to the T-beam / bulkhead through an L-shaped angle steel 18. One end of the L-shaped angle steel 18 is fixedly connected to the T-beam / bulkhead, and the other end is provided with a slotted round hole and coincides with the relief hole 9 of the side plate 32, and is connected to the side plate 32 through a riveted round bolt 28.

[0042] Those of ordinary skill in the art should understand that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
