Description

Technical Field

[0001] The present invention particularly relates to a cable laying device. Background Art

[0002] A large number of cable laying operations are required on ships. Cables on ships are used to transmit electricity, provide necessary energy for the ship's propulsion system, navigation equipment, communication system, lighting, daily living facilities, etc., and are used to transmit control signals and sensor signals to ensure the normal operation of the ship's automation system, monitoring system and safety system. However, ship cables may cause failures and accidents due to aging, wear or loose joints during long-term operation, so cables need to be maintained and repaired regularly to ensure the reliability of power and signal transmission. Through regular inspection and maintenance, small problems can be prevented from turning into major failures, reducing the need for emergency repairs and related costs.

[0003] When laying cables on the front of the deck, holes need to be made to meet the requirements of cable laying safety. However, some decks do not have the conditions for making holes. Making holes in key parts of the hull structure may affect the structural integrity and strength of the hull. Therefore, it is necessary to avoid making holes in these areas. At present, the general way to solve the problem of laying cables on decks that do not have the conditions for making holes is to use closed protection measures after laying the cables directly on the deck. Cables laid directly on the deck are prone to mechanical damage caused by trampling and deformation, so protective measures need to be taken for protection. However, the use of closed protection measures will cause the cables to be enclosed in the cable trough after installation, which is not conducive to later maintenance. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a cable laying device in order to overcome the defect that the protective measures using a closed structure in the prior art are not conducive to later maintenance.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A cable laying device is applied to ships and used for protecting cables. The cable laying device comprises a trough body and a cover plate. The trough body has a cable trough. The top of the trough body has an opening, which is connected to the cable trough. The cable is placed in the cable trough through the opening. The cover plate is detachably connected to the opening.

[0007] In the present solution, in the previous technology, the use of closed protective measures will cause the cables to be enclosed in the cable trough after installation, which is not conducive to later maintenance. Therefore, compared with the previous technology, the above-mentioned structural form is adopted. In the present invention, the cover plate is detachably connected to the opening of the trough body, which can be easily disassembled to open the cable laying device to inspect or maintain the cables laid inside, avoiding the problem of difficulty in inspecting or maintaining the cables when closed protective measures are used, improving the efficiency of cable maintenance, and ensuring that the cables maintain good conductivity, thereby improving the operating efficiency and performance of the ship.

[0008] Preferably, the trough body includes a bottom plate, a plurality of side walls and a plurality of connectors, the bottom plate is connected to the plurality of side walls to form the cable trough, and the plurality of connectors are connected to the side walls.

[0009] In this solution, a space for accommodating cables is formed by the bottom plate and the side walls, and the cable laying device can be quickly disassembled and assembled through connectors arranged on the side walls, thereby quickly sealing the cables while improving the work efficiency of cable maintenance personnel.

[0010] Preferably, the connecting member includes a first connecting portion, one end of which is connected to the top end of the side wall, the other end of which extends in a horizontal direction, and the cover plate is placed on and connected to the first connecting portion.

[0012] Preferably, the first connecting portion has a connecting hole, and the connecting hole is detachably connected to the cover plate via a fastener.

[0013] In this solution, the fasteners can be installed and disassembled multiple times, which is convenient for maintenance and replacement of parts and improves the efficiency of cable maintenance. In addition, the fastener connection cost is low and suitable for large-scale production, which is conducive to reducing the construction cost of laying cables on ships.

[0014] Preferably, the connecting member further comprises a second connecting portion, the second connecting portion is attached to the side wall and connected to the side wall, and the top end of the second connecting portion is connected to the first connecting portion.

[0015] In this solution, by attaching and connecting the second connection part to the side wall to provide a fulcrum, the top end of the second connection part is connected to the first connection part, which can provide support for the first connection part and further improve the stability of the connection between the cover plate and the trough body.

[0016] Preferably, the first connecting portion and the second connecting portion are integrally formed.

[0017] In this solution, by integrally forming the first connection part and the second connection part, the strength of the second connection part supporting the first connection part can be increased, making the connection between the cover plate and the trough body more reliable.

[0018] Preferably, the cable trough penetrates the trough body along the length direction of the trough body.

[0019] In this solution, by passing the cable trough through the trough body, the cable can be protected from damage when passing through the cable laying device, and the cable can also be prevented from being affected by external factors such as corrosion and wear.

[0022] Preferably, the cable laying device further comprises a plurality of splicing pieces, and two ends of the splicing pieces are respectively connected to two adjacent trough bodies.

[0023] In this solution, by using multiple splicing pieces, the number of splicing pieces to be installed can be selected according to actual needs when connecting the trough body, thereby meeting the required cable laying length and improving the laying flexibility.

[0024] Preferably, the cover plate comprises a plate body and a support portion, the top end of the support portion is connected to the cover plate, and extends perpendicularly to the cover plate toward the trough body and abuts against the trough body.

[0025] In this solution, since there is a large cavity in the cable trough, the middle part of the cover plate is easily deformed by pressure. By providing the support part, the cover plate can be supported from the inside, thereby improving the compressive strength of the cable laying device, preventing the cover plate from being deformed and causing mechanical damage due to trampling, and improving the service life of the cable laying device.

[0057] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0058] This embodiment provides a cable laying device 100, which is applied to ships and used to protect cables 3, such as Figure 1-8 As shown, the cable laying device 100 includes a slot body 1 and a cover plate 2. The slot body 1 has a cable slot 4. Figure 8 As shown, the top of the trough body 1 has an opening 5, the opening 5 is connected to the cable trough 4, the cable 3 is placed in the cable trough 4 through the opening 5, and the cover plate 2 is detachably connected to the opening 5.

[0059] Therefore, in the previous technology, the use of closed protection measures will cause the cable 3 to be enclosed in the cable trough 4 after installation, which is not conducive to subsequent maintenance. Therefore, compared with the previous technology, the above-mentioned structural form is adopted. In the present invention, the cover plate 2 is detachably connected to the opening 5 of the trough body 1, which can be easily disassembled to open the cable laying device 100 to inspect or maintain the cable 3 laid inside, thereby avoiding the problem of difficulty in inspecting or maintaining the cable 3 using closed protection measures, improving the efficiency of cable 3 maintenance, and ensuring that the cable 3 maintains good conductivity, thereby improving the operating efficiency and performance of the ship.

[0060] The cable laying device 100 is suitable for laying cables 3 on the front of the deck, and is particularly suitable for laying cables 3 in areas where the deck does not have openings. The device is used for laying cables 3 for electrical equipment on equipment or furniture in the deck area. While complying with the cable 3 laying process, it also meets the heat dissipation requirements of the cables 3 and the later maintenance requirements and the strength requirements of the cable trough 4 structure. The cable laying device 100 can be used in areas where the deck does not have openings or where the raised floor is not installed, to ensure the performance integrity of the reverse area. In addition, this solution can play an advantage in ship modification projects without destroying the bottom area, saving costs for shipowners while providing construction convenience for shipyards.

[0061] In this embodiment, the cover plate 2 is 110 mm wide, and the trough body 1 is 100 mm wide. The trough body 1 and the cover plate 2 may be made of galvanized steel plates, or other materials deemed appropriate by those skilled in the art.

[0062] Specifically, Figure 3 and Figure 5 As shown, the trough body 1 includes a bottom plate 6, a plurality of side walls 7 and a plurality of connectors 8. The bottom plate 6 is connected with the plurality of side walls 7 to form a cable trough 4. The plurality of connectors 8 are connected to the side walls 7. The cable trough 4 runs through the trough body 1 along its length direction.

[0063] Thus, a space for accommodating the cable 3 is formed by the bottom plate 6 and the side wall 7, and the cable laying device 100 can be quickly assembled and disassembled by the connector 8 provided on the side wall 7, thereby improving the work efficiency of the cable 3 maintenance staff and quickly sealing the cable 3. The cable 3 can be protected from damage when passing through the cable laying device 100 by passing the cable trough 4 through the trough body 1, and the cable 3 can also be prevented from being affected by external factors such as corrosion and wear.

[0064] In this embodiment, there are two side walls 7, and the bottoms of the two side walls 7 are respectively vertically connected to the two opposite ends of the bottom plate 6, thereby forming a rectangular cable trough 4 with an upper opening 5. Connectors 8 are arranged at intervals on the two side walls 7 of the trough body 1, and a connector 8 is arranged every 180 mm.

[0065] Specifically, Figure 6 As shown, the connecting member 8 includes a first connecting portion 9, one end of which is connected to the top end of the side wall 7, and the other end of the first connecting portion 9 extends in the horizontal direction, and the cover plate 2 is placed on the first connecting portion 9 and connected to the first connecting portion 9. The first connecting portion 9 has a first connecting hole 10, and the first connecting hole 10 is detachably connected to the cover plate 2 through a fastener.

[0066] Thus, by setting one end of the first connection part 9 at the top of the side wall 7 and the other end extending horizontally, the cover plate 2 can be closely attached to the first connection part 9 by adopting the above structure, so as to achieve a firm connection. The use of fasteners can achieve multiple installation and disassembly, facilitate maintenance and replacement of parts, and improve the work efficiency of maintaining the cable 3. In addition, the fastener connection cost is low and suitable for large-scale production, which is conducive to reducing the construction cost of laying the cable 3 on the ship.

[0067] In this embodiment, the first connection hole 10 of the first connection part 9 is a bolt 16 hole, and a second connection hole 11 is provided at a position corresponding to the first connection hole 10 on the cover plate 2, and the second connection hole 11 is also a bolt 16 hole. The fastener is a bolt 16, and the cover plate 2 is connected to the tank body 1 by passing the bolt 16 through the first connection hole 10 and the second connection hole 11. The first connection part 9 is a rectangular metal sheet with a long side of 20 mm and a short side of 15 mm, and the distance between the first connection hole 10 and the side wall 7 is 7 mm. In other embodiments, the first connection hole 10 and the second connection hole 11 can also be pin holes, and the fastener can also be a pin. Those skilled in the art can also select other fasteners to detachably connect the cover plate 2 to the tank body 1.

[0068] Specifically, the connecting member 8 further includes a second connecting portion 12, which is attached to and connected to the side wall 7, and the top end of the second connecting portion 12 is connected to the first connecting portion 9. The first connecting portion 9 and the second connecting portion 12 are integrally formed.

[0069] Thus, by attaching and connecting the second connection part 12 to the side wall 7 to provide a fulcrum, the top end of the second connection part 12 is connected to the first connection part 9, which can provide support for the first connection part 9, further improving the stability of the connection between the cover plate 2 and the tank body 1. By integrally forming the first connection part 9 and the second connection part 12, the strength of the second connection part 12 supporting the first connection part 9 can be improved, making the connection between the cover plate 2 and the tank body 1 more reliable.

[0070] In this embodiment, the second connection part 12 is a sheet metal, which is welded to the side wall 7 of the trough body 1 in a fitting manner, and the top of the second connection part 12 is connected to the first connection part 9 to provide support. In other embodiments, the second connection part 12 can also be welded to the bottom plate 6 of the trough body 1 in a manner perpendicular to the side wall 7, and the top of the second connection part 12 is connected to the side of the first connection part 9 to provide support. Connecting in a fitting manner can save the lateral space of the cable trough 4, and connecting in a manner perpendicular to the side wall 7 can provide a stronger support force for the first connection part 9.

[0071] Specifically, the cable laying device 100 further includes a grounding pole and a cable tie 17 .

[0072] Thus, grounding the cable laying device 100 through the grounding pole helps maintain the stability of the power system. The cable tie 17 is used to bundle the cables 3, which can facilitate the management and protection of the cable line, and can also keep the cables 3 neat and orderly, prevent the cables 3 from being messy and damaged, and also facilitate maintenance and repair work.

[0073] In this embodiment, Figure 1 As shown, the cables 3 are bundled by cable ties 17 , and a gap is provided between the bundled cables 3 and the inner wall of the slot body 1 , which helps the cables 3 to dissipate heat.

[0074] Specifically, there are multiple trough bodies 1, and the multiple trough bodies 1 are spliced ​​with each other along their length direction.

[0075] Therefore, by splicing a plurality of trough bodies 1 along the length direction, long-distance cable 3 laying can be achieved to meet the needs of cable 3 laying operations on ship decks.

[0076] In this embodiment, the length direction of the trough body 1 is the extension direction of the cable 3 laid in the trough body 1, and multiple trough bodies 1 are placed along the laying direction of the cable 3, and two adjacent trough bodies 1 are connected end to end for splicing. The splicing between the trough bodies 1 can be connected by welding or fasteners. Preferably, fasteners are used for detachable connection, and the fastener connection allows multiple installation and disassembly, which is convenient for maintenance and replacement of parts.

[0077] Specifically, Figure 7 As shown, the cable laying device 100 further includes a plurality of splicing pieces 13 , and two ends of the splicing pieces 13 are respectively connected to two adjacent slots 1 .

[0078] Therefore, when connecting the trough body 1, the number of splicing pieces to be installed can be selected according to actual needs through the multiple splicing pieces 13 to meet the required laying length of the cable 3, thereby improving the laying flexibility.

[0079] In this embodiment, two adjacent tank bodies 1 are connected by a splicing piece 13. Figure 6 and Figure 7As shown, the first end of the trough body 1 is provided with a third connection hole 18 and the last end is provided with a fourth connection hole 19, the distance between the third connection hole 18 and the first end edge of the trough body 1 is 17 mm, and the distance between the fourth connection hole 19 and the last end edge of the trough body 1 is 17 mm. The splicing piece 13 is a metal sheet, and the splicing piece 13 is provided with two connection holes, and the center distance between the two connection holes is 32 mm. One of the connection holes of the splicing piece 13 is connected to the third connection hole 18, and the other connection hole of the splicing piece 13 is connected to the fourth connection hole 19. The splicing piece 13 is connected to the two trough bodies 1 by bolts 16. In other embodiments, those skilled in the art may also choose other detachable connection methods. In order to strengthen the connection strength of the connection area of ​​the trough body 1, the splicing piece 13 may also include a first connection portion 9, one end of the first connection portion 9 is connected to the top of the splicing piece 13, and the other end of the first connection portion 9 extends in the horizontal direction, and the cover plate 2 is placed on the first connection portion 9 and connected to the first connection portion 9. The first connecting portion 9 has a first connecting hole 10 , and the first connecting hole 10 is detachably connected to the cover plate 2 via a fastener.

[0080] Specifically, Figure 2 and Figure 4 As shown, the cover plate 2 includes a plate body and a support portion 15 . The top end of the support portion 15 is connected to the cover plate 2 , and extends perpendicularly to the cover plate 2 toward the trough body 1 and abuts against the trough body 1 .

[0081] Therefore, due to the presence of a large cavity in the cable trough 4, the middle part of the cover plate 2 is easily deformed by pressure. By providing the support portion 15, the cover plate 2 can be supported from the inside, thereby improving the compressive strength of the cable laying device 100, preventing the cover plate 2 from being deformed and causing mechanical damage due to trampling and other behaviors, and improving the service life of the cable laying device 100.

[0082] In this embodiment, the support portion 15 is a rectangular support column. In other embodiments, the support portion 15 may also be a circular column or other shapes. The top of the support portion 15 may be connected to the cover plate 2, which may be connected to the bottom plate 6 of the trough body 1. There are multiple support portions 15, and multiple support columns are arranged at intervals along the center line of the cover plate 2, thereby dividing the cable laying device 100 into two cable 3 laying areas, or multiple straight lines are arranged at intervals along the length direction of the cover plate 2, dividing the cable laying device 100 into multiple cable 3 laying areas. A buffer component may also be provided at the support portion 15 and the connection between the trough body 1 and the cover plate 2 to absorb impact force and protect the cable 3 from mechanical shock and pressure.
