Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and particularly to a cable laying device for ships. Background Art

[0002] In the process of modern shipbuilding and maintenance, cable laying is a crucial task. As the carrier of internal power transmission, signal transmission, and control systems in ships, the laying quality of cables directly affects the performance and safety of ships. Traditional cable laying methods mainly rely on manual operations, which are not only inefficient but also prone to errors, resulting in chaotic cable layouts and difficult maintenance. With the continuous development of technology, existing cable laying devices can reduce manual operations and improve the efficiency of cable laying. For example, a cable laying device for ship radio equipment disclosed in the publication number: CN116505439A can effectively straighten the cables inside the cable tray during use, avoid the cables from bending or winding around each other inside the cable tray, and at the same time fix the straightened cables. However, it still requires manual traction of the cables into the cable tray before subsequent operations can be carried out, and cannot reduce manual operations. In addition, when straightening and fixing the cables inside the cable tray, only single cables can be fixed in the middle of the cable tray, and the positions of the remaining cables cannot be adjusted, resulting in an inability to improve the layout of the cables inside the cable tray and poor device usage effects. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the background art and propose a cable laying device for ships.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] In the above-mentioned cable laying device for ships, a spring plate is slidably installed on the top of the positioning block. The spring plate is located below the support plate. A first spring is provided between the bottom of the spring plate and the top of the positioning block. A wire groove is provided on the side wall of the positioning block. A rotating roller is rotatably installed at the bottom of the positioning block. The wire groove is located between the rotating roller and the third chute. The wire groove is fixedly connected with the side wall of the cable channel.

[0009] In the above-mentioned cable laying device for ships, a first screw rod and two first sliding rods are integrally formed at the bottom of the vehicle frame. The first screw rod is located between the two first sliding rods. A fixing frame is fixedly installed at the bottom of the first sliding rod. A moving frame is movably installed below the vehicle frame. The fixing frame is located inside the moving frame. The moving frame is slidably installed on the outside of the fixing frame.

[0010] In the above-mentioned cable laying device for ships, a gear nut is rotatably installed at the top of the moving frame. The gear nut is rotatably installed on the outside of the first screw rod. A third motor is fixedly installed at the top of the moving frame. The output shaft of the third motor is fixedly connected to a third gear. The third gear meshes with the gear nut. Both of the two first sliding rods penetrate through the top of the moving frame.

[0011] In the above-mentioned cable laying device for ships, a plurality of evenly distributed second wire drums are fixedly installed at the bottom of the fixing frame. A plurality of evenly distributed rotating rings are rotatably installed on the side wall of the fixing frame. The rotating rings correspond to the second wire drums one by one. Two semi-circular wire drums are slidably installed inside each rotating ring. A second spring is provided between the two semi-circular wire drums.

[0012] In the above-mentioned cable laying device for ships, a wire gathering frame is welded at the bottom of the vehicle frame. A cable channel is fixedly installed on the side wall of the wire gathering frame. A first wire drum is integrally formed on the side wall of the wire gathering frame. The first wire drums correspond to the rotating rings one by one. The rotating rings are located between the first wire drums and the second wire drums. A plurality of evenly distributed circular grooves are formed at the bottom of the moving frame. The circular grooves correspond to the second wire drums one by one. Concave teeth are provided on the peripheral wall of the second wire drum. Convex teeth are integrally formed on the side wall of the circular groove. The convex teeth are located below the concave teeth.

[0013] Compared with the existing technology, the advantages of the present invention are as follows:

[0014] 1. Through the cooperation between the two semi-circular wire drums and the conversion, before cable laying, after manually passing the cable through the second wire drum and the two semi-circular wire drums, the two semi-circular wire drums clamp the cable through the second spring. When the vehicle frame moves into the bridge frame, the two semi-circular wire drums pull the cable into the bridge frame. During the pulling process, the outer peripheral wall of the semi-circular wire drum abuts against the inner peripheral wall of the conversion, making the clamping effect of the semi-circular wire drum better. When the cable twists itself, the cable drives the rotating ring to rotate, thereby reducing the torsional force of the cable itself and preventing the cables from winding around each other. When it is necessary to release the clamping of the cable, the vehicle frame moves in the reverse direction, and the cable drives the two semi-circular wire drums to move, so that the inner peripheral wall of the semi-circular wire drum abuts against the side wall of the first wire drum, and the semi-circular wire drum is unlocked. The cable directly enters the inside of the first wire drum without manual re-threading, reducing manual intervention.

[0015] 2. Through the cooperation between the wire pressing roller and the positioning block, when the cable is towed, the second motor drives the bidirectional screw, the bidirectional nut drives the positioning block to move horizontally back and forth, the wire pressing roller moves along with the positioning block, and the positioning block detects within the internal space of the cable bridge. When the positioning block slides downward and touches the bottom surface inside the cable bridge, the positioning block and the wire pressing roller are locked horizontally, thereby determining the cable laying position. This enables the cable position to be adjusted manually no more during cable laying, and the wire pressing roller can lay multiple cables, improving the work efficiency while reducing manual intervention.

[0016] 3. Through the cooperation between the wire pressing roller and the second wire drum, when the cable is laid, the moving frame moves upward, causing the convex teeth to touch the concave teeth, and a top block is formed on the inner wall of the second wire drum. When the vehicle frame moves, the wire pressing roller rotates and pulls the cable in the opposite direction of the vehicle frame movement, and the second wire drum slides outside the cable and pushes the cable in the direction of the vehicle frame movement, making the cable between the wire pressing roller and the second wire drum straight. Additionally, through the sliding of the second wire drum outside the cable, the torsional force of the cable itself is transferred to the end of the cable, eliminating the torsional force of the cable itself and ensuring that the laid cables do not wind around each other anymore.

Detailed implementation manners

[0031] 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.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0033] Refer to Figure 1 - Figure 13As shown in the figure, a cable laying device for ships includes a vehicle frame 1, a first wheel 11 and a second wheel 121. The first wheel 11 is rotatably installed on the side wall of the vehicle frame 1. An axle 122 is rotatably installed at the bottom of the vehicle frame 1. The second wheels 121 are rotatably installed at both ends of the axle 122. The first wheel 11 and the second wheels 121 are respectively located at both ends of the bottom of the vehicle frame 1. A second chute 17 is provided on the side wall of the vehicle frame 1. A first rotating shaft 213 is movably installed inside the second chute 17. The second wheels 121 are located between the first rotating shaft 213 and the first wheel 11. A wire pressing roller 22 is slidably sleeved on the outer peripheral wall of the first rotating shaft 213. A second pulley 211 is fixedly installed on the side wall of the first rotating shaft 213. A first pulley 126 is integrally formed on the side wall of the second wheel 121. A first belt 212 is provided between the first pulley 126 and the second pulley 211. A first motor 124 is fixedly installed on the side wall of the vehicle frame 1. The output shaft of the first motor 124 is fixedly connected to a second gear 125. A first gear 123 is fixedly installed on the side peripheral wall of the axle 122. The first gear 123 and the second gear 125 are meshed with each other. A positioning block 32 is movably installed below the vehicle frame 1. The positioning block 32 is located between the first wheel 11 and the second wheels 121. A limiting bracket 23 is welded on the side wall of the positioning block 32. Two rotating holes 231 are integrally formed on the side wall of the limiting bracket 23. Both of the two rotating holes 231 are movably installed outside the first rotating shaft 213. The wire pressing roller 22 is located between the two rotating holes 231.

[0034] Among them, the working principle of the wire pressing roller 22 is as follows: After the vehicle frame 1 pulls the cable to be laid into the cable tray, the first motor 124 rotates reversely, and the first wheel 11 and the second wheels 121 rotate reversely, so that the vehicle frame 1 moves in the reverse direction. The second wheels 121 drive the first rotating shaft 213 to rotate through the first belt 212. The rotating directions of the first rotating shaft 213 and the second wheels 121 are always the same. The first rotating shaft 213 drives the wire pressing roller 22 to rotate. The wire pressing roller 22 abuts against the upper part of the cable and rotates, so that the cable is straightened.

[0035] Further referring to Figure 7 and Figure 9 for description, the working principle of the limiting bracket 23 is that when the vehicle frame 1 pulls the cable into the cable tray, the positioning block 32 drives the wire pressing roller 22 to move through the limiting bracket 23. When the positioning block 32 is locked, the wire pressing roller 22 is also locked. When the positioning block 32 is locked, the positioning block 32 drives the first rotating shaft 213 to slide downward along the second chute 17 through the limiting bracket 23, so that the wire pressing roller 22 abuts against the cable.

[0036] Such as Figures 1 - 3 and Figures 5 - 8As shown in the figure, a second motor 312 is fixedly installed on the side wall of the vehicle frame 1. The output shaft of the second motor 312 is fixedly connected to a bidirectional screw 31. A second slide bar 143 is welded to the side wall of the vehicle frame 1. A bidirectional nut 311 is slidably installed on the outer peripheral wall of the second slide bar 143. A slide hole 313 is formed in the side wall of the bidirectional nut 311. The second slide bar 143 is located inside the slide hole 313. The bidirectional screw 31 is rotatably installed inside the bidirectional nut 311. A third chute 323 is formed in the side wall of the positioning block 32. The bidirectional nut 311 is movably installed inside the third chute 323. A limiting plate 324 is integrally formed on both sides of the bottom of the third chute 323. The bidirectional nut 311 is located between the two limiting plates 324.

[0037] Among them, the working principle of the bidirectional nut 311 is as follows: After the second motor 312 starts and drives the bidirectional screw 31 to rotate, the bidirectional nut 311 slides along the second slide bar 143 inside the third chute 323. When the bidirectional nut 311 abuts against the limiting plate 324, the positioning block 32 moves horizontally along the outer side of the cable inside the bridge frame following the bidirectional nut 311. When the positioning block 32 slides downward, the bidirectional nut 311 disengages from the limiting plate 324, causing the bidirectional nut 311 to reciprocally insert into the third chute 323.

[0038] As Figures 1 - 3 and Figures 5 - 8 shown in the figure, a support plate 14 is welded to the side wall of the vehicle frame 1. The support plate 14 is located above the second slide bar 143. A first chute 141 is formed in the side wall of the support plate 14. A third slide bar 322 is integrally formed on the top of the positioning block 32. The third slide bar 322 is slidably installed inside the first chute 141. A tooth surface 142 is integrally formed on the top of the support plate 14. A tooth plate 326 is provided at the top of the third slide bar 322. The tooth plate 326 is located above the tooth surface 142. A spring plate 325 is slidably installed on the top of the positioning block 32. The spring plate 325 is located below the support plate 14. A first spring 331 is provided between the bottom of the spring plate 325 and the top of the positioning block 32. A wire groove 327 is formed in the side wall of the positioning block 32. A rotating roller 321 is rotatably installed at the bottom of the positioning block 32. The wire groove 327 is located between the rotating roller 321 and the third chute 323.

[0039] Among them, the working principle of the positioning block 32 is as follows: When the bidirectional nut 311 drives the positioning block 32 to move, the positioning block 32 slides along the first chute 141 through the third slide bar 322. Through the extrusion of the spring plate 325 and the first spring 331 on the positioning block 32, the positioning block 32 is always pressed against the bottom of the bridge frame. When the positioning block 32 abuts against the bottom of the bridge frame, the bidirectional nut 311 disengages from the limiting plate 324, and the tooth plate 326 abuts against the tooth surface 142, locking the positioning block 32.

[0040] As Figure 1 、 Figure 2 、 Figure 10 andFigure 11 As shown, a first screw rod 131 and two first slide rods 132 are integrally formed at the bottom of the vehicle frame 1. The first screw rod 131 is located between the two first slide rods 132. A fixing frame 42 is fixedly installed at the bottom of the first slide rod 132. A moving frame 41 is movably installed below the vehicle frame 1. The fixing frame 42 is located inside the moving frame 41. The moving frame 41 is slidably installed on the outside of the fixing frame 42. A gear nut 411 is rotatably installed at the top of the moving frame 41. The gear nut 411 is rotatably installed on the outside of the first screw rod 131. A third motor 415 is fixedly installed at the top of the moving frame 41. The output shaft of the third motor 415 is fixedly connected to a third gear 414. The third gear 414 meshes with the gear nut 411. Both of the two first slide rods 132 penetrate through the top of the moving frame 41.

[0041] As Figure 4 and Figures 10 - 13 shown, a plurality of evenly distributed second wire drums 431 are fixedly installed at the bottom of the fixing frame 42. A plurality of evenly distributed rotating rings 432 are rotatably installed on the side wall of the fixing frame 42. The rotating rings 432 and the second wire drums 431 are in one-to-one correspondence. Two semi-circular wire drums 433 are slidably installed inside each rotating ring 432. A second spring 434 is provided between the two semi-circular wire drums 433. A wire gathering frame 16 is welded to the bottom of the vehicle frame 1. A cable channel 15 is fixedly installed on the side wall of the wire gathering frame 16. The side wall of the wire groove 327 is fixedly connected to the side wall of the cable channel 15. A first wire drum 161 is integrally formed on the side wall of the wire gathering frame 16. The first wire drum 161 and the rotating rings 432 are in one-to-one correspondence. The rotating rings 432 are located between the first wire drum 161 and the second wire drums 431. A plurality of evenly distributed circular grooves 412 are formed at the bottom of the moving frame 41. The circular grooves 412 and the second wire drums 431 are in one-to-one correspondence. A concave tooth 435 is provided on the circumferential wall of the second wire drum 431. A convex tooth 413 is integrally formed on the side wall of the circular groove 412. The convex tooth 413 is located below the concave tooth 435.

[0042] Among them, the working principle of the semi-circular wire drum 433 is as follows: When the vehicle frame 1 enters the inside of the bridge frame to pull in the cable, the cable is manually passed through the second wire drum 431 and the two semi-circular wire drums 433. The two semi-circular wire drums 433 clamp the cable through the second spring 434. When the vehicle frame 1 pulls the cable, the cable pulls the two semi-circular wire drums 433 and rotates. Through the contact between the outer circumferential wall of the semi-circular wire drum 433 and the inner circumferential wall of the rotating ring 432, the semi-circular wire drum 433 continuously strengthens the clamping of the cable. When the vehicle frame 1 enters the inside of the bridge frame to lay the cable, the cable pushes the two semi-circular wire drums 433. Through the contact between the inner circumferential wall of the semi-circular wire drum 433 and the side wall of the first wire drum 161, the two semi-circular wire drums 433 are opened to release the clamping of the cable. The cable sequentially passes through the first wire drum 161, the wire gathering frame 16, the cable channel 15 and the wire groove 327 to the lower part of the wire pressing roller 22. The middle section of the cable channel 15 can be bent so that the cable can smoothly enter the inside of the wire groove 327.

[0043] Further reference is made to Figure 10 , Figure 12 and Figure 13 for description. The working principle of the moving frame 41 is as follows: When the vehicle frame 1 enters the inside of the bridge frame to pull in the cable, the second cable drum 431 is movably sleeved on the outer peripheral wall of the cable. When the vehicle frame 1 enters the inside of the bridge frame to lay the cable, the third motor 415 rotates in reverse, causing the moving frame 41 to move upward. The circular groove 412 abuts against the second cable drum 431, and the convex teeth 413 abut against the concave teeth 435, causing a top block 436 to be formed on the inner wall of the second cable drum 431. At this time, when the vehicle frame 1 moves, the top block 436 abuts against the bottom of the cable, causing the second cable drum 431 to slidably sleeve on the outer peripheral wall of the cable.

[0044] The following makes a detailed explanation of the specific working principle and usage method of the present invention: The worker passes the cable through the second cable drum 431 and the two semi-circular cable drums 433. After the two semi-circular cable drums 433 clamp the cable through the second spring 434, the first motor 124 is started and rotates forward. The vehicle frame 1 pulls the cable and moves it into the inside of the bridge frame. The second motor 312 is started, and the bidirectional screw 31 rotates. The bidirectional nut 311 drives the positioning block 32 and the wire pressing roller 22 to move horizontally. When the bottom of the positioning block 32 disengages from the cable laid inside the bridge frame, the positioning block 32 drives the wire pressing roller 22 to slide downward and lock. When all the cables enter the inside of the bridge frame, the vehicle frame 1 lays the cables inside the bridge frame. The first motor 124 rotates in reverse, causing the vehicle frame 1 to move in the reverse direction. The cable pushes the semi-circular cable drum 433, causing the semi-circular cable drums 433 to come into contact and clamp. After the cable passes through the first cable drum 161, the wire gathering frame 16, the cable channel 15, and the wire groove 327 in sequence, the worker passes the cable under the wire pressing roller 22. The third motor 415 is started and rotates in reverse. After a top block 436 is formed on the inner wall of the second cable drum 431, the vehicle frame 1 enters the inside of the bridge frame to lay the cable.

[0045] Further explanation is made that the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0046] As described above, only the preferred specific implementation manners of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
