Description

Technical Field

[0001] This utility model belongs to the technical field of cable tray troughs, specifically a flame-retardant and heat-insulating composite marine cable tray trough. Background Technology

[0002] Flame-retardant and heat-insulating composite marine cable trays are cable support and protection devices specifically designed for marine environments. They combine multiple materials to achieve flame-retardant and heat-insulating properties. These trays typically consist of a flame-retardant outer shell and a flame-retardant and heat-insulating sandwich panel, using a composite structure to enhance overall flame-retardant and heat-insulating effects. Their application is primarily concentrated in the shipbuilding industry, used to support and protect shipboard cable systems, ensuring the safe and trouble-free operation of electrical and communication facilities. In the harsh marine environment, these composite marine cable trays effectively resist corrosion, high temperatures, and other adverse factors, ensuring the stable operation of the ship's electrical system and making them an indispensable and important component of modern shipbuilding.

[0003] Existing composite marine cable trays typically use a downward pressing method to position cables, which means that cables can only be inserted into the tray and cannot be lowered directly from the top, making cable installation very inconvenient. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a flame-retardant and heat-insulating composite marine cable tray trough, which effectively solves the problem that the existing composite marine cable tray troughs usually use a downward pressing and fixing method to position the cable, which results in the cable being able to only pass through the inside of the trough and not being able to be directly lowered from the top.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant and heat-insulating composite marine cable tray trough, comprising a trough body, a top cover detachably mounted on the top of the trough body by bolts, clamping strips at both ends of the inner part of the trough body, anti-slip pads fixedly mounted on one side of each of the four clamping strips, handles at the middle of both sides of the trough body, support arms fixedly mounted at the middle of each of the two handles, connecting strips fixedly mounted at the lower part of each of the two support arms, limit sliding rods fixedly mounted on the side of each of the four connecting strips near the trough body, and two limit rods respectively provided at the lower part of both sides of the trough body. The slide hole has four limiting slide rods that are slidably installed inside the two limiting slide holes. Two insertion holes are opened in the middle of both sides of the groove. Two insertion rods are fixedly installed on the side of the two support arms that are close to each other. The four insertion rods are adapted to the four insertion holes. The four insertion rods have installation grooves inside. Locking parts are installed inside the four installation grooves. Transmission components are provided at both ends of the side of the two support arms that are close to each other. The four transmission components are connected to the four pressing bars. When the two pressing bars move, the four pressing bars are driven to rotate downwards to press the cable through the four transmission components.

[0006] Preferably, each of the four transmission components includes a connecting frame. The four connecting frames are respectively fixedly installed at both ends of the two support arms on the side close to each other. One end of each of the four connecting frames extends into the interior of the groove and is fixedly installed with a transmission pin. The middle of each of the four clamping bars is provided with a transmission groove, and the four transmission pins are respectively movably inserted into the interior of the four transmission grooves. The lower end of each of the four clamping bars is fixedly installed with a rotating shaft. Both ends of each of the four rotating shafts are rotatably installed with a bearing seat, and one side of each bearing seat is fixedly connected to the inner wall of the groove.

[0007] Preferably, each of the four locking components includes a support plate, the four support plates are fixedly installed in the middle of the four mounting slots, a rectangular rod is fixedly installed in the middle of each of the four support plates, and a locking block is movably inserted into both sides of one end of each of the four plug-in rods. A rectangular slot is opened on the side of the locking block near the support plate, and both ends of the four rectangular rods are respectively inserted into the corresponding rectangular slots. Springs are sleeved on both ends of the surface of the four rectangular rods, and both ends of the springs are respectively fixedly connected to the support plate and the locking block.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator can directly put the cable into the inside of the tank from the upper opening of the tank, and then push the two support arms in opposite directions through the two handles. When the two support arms move, the connecting strip drives the limiting slide rod to slide along the inside of the limiting slide hole, which increases the stability of the two support arms when moving. When the two support arms move in opposite directions, the four connecting frames slide in the inside of the four transmission slots through the four transmission pins, thereby causing the four pressing strips to drive the four anti-slip pads to rotate downward along the four rotating shafts to press the cable.

[0009] As the two support arms move towards each other, four plug-in rods insert into the four plug-in holes. Simultaneously, each plug-in rod pushes a locking block to move into the mounting groove and retracts, sliding along the surface of the rectangular rod through the rectangular groove. At the same time, the spring is compressed. When the four plug-in rods drive the locking block through the plug-in hole, the spring force pushes the locking block outward to reset, thus forming a locking engagement with the groove body to ensure the stability of the compressed cable. This composite marine cable tray groove allows cables to be directly inserted from the top and compressed, making cable installation very convenient. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1 to 5 The present invention includes a trough 1, a top cover 2 detachably mounted on the top of the trough 1 by bolts, a clamping strip 19 at both ends inside the trough 1, an anti-slip pad 3 fixedly mounted on one side of each of the four clamping strips 19, a handle 4 in the middle of both sides of the trough 1, a support arm 5 fixedly mounted in the middle of each of the two handles 4, a connecting strip 6 fixedly mounted on the lower part of each of the two support arms 5, a limiting slide rod 7 fixedly mounted on the side of each of the four connecting strips 6 near the trough 1, and two limiting slide holes 8 respectively opened in the lower part of both sides of the trough 1, with the four limiting slide rods 7 slidably mounted inside the two limiting slide holes 8 respectively.

[0020] Two insertion holes 9 are respectively opened in the middle of both sides of the groove 1. Two insertion rods 10 are fixedly installed on the side of the two support arms 5 that are close to each other. The four insertion rods 10 are adapted to the four insertion holes 9. The interior of the four insertion rods 10 is provided with a mounting groove 11. The interior of the four mounting grooves 11 is provided with a locking component. The two ends of the side of the two support arms 5 that are close to each other are provided with a transmission component. The four transmission components are respectively connected to the four pressing strips 19. When the two pressing strips 19 move, the four pressing strips 19 are driven to rotate downwards to press the cable through the four transmission components.

[0021] When in use, the operator can directly put the cable into the inside of the tank 1 from the upper opening of the tank 1, and then push the two support arms 5 in opposite directions through the two handles 4. When the two support arms 5 move, the limiting slide rod 7 is driven by the connecting strip 6 to slide along the inside of the limiting slide hole 8, which increases the stability of the two support arms 5 when moving.

[0022] When the two support arms 5 move toward each other, they will push the four clamping bars 19 through the four transmission components, causing the four anti-slip pads 3 to rotate downwards along the four rotating shafts 21 to clamp the cable; at the same time, the four locking parts can form a locking engagement with the trough body 1 to ensure the stability of the clamped cable; this composite marine cable tray trough body allows the cable to be directly placed into its interior from the top and clamped, making the cable installation very convenient.

[0023] Each of the four transmission components includes a connecting frame 17. The four connecting frames 17 are respectively fixedly installed at both ends of the two support arms 5 on the side close to each other. One end of each of the four connecting frames 17 extends into the interior of the groove 1 and is fixedly installed with a transmission pin 18. The middle of each of the four clamping bars 19 is provided with a transmission groove 20, and the four transmission pins 18 are respectively movably inserted into the interior of the four transmission grooves 20. The lower end of each of the four clamping bars 19 is fixedly installed with a rotating shaft 21. Both ends of each of the four rotating shafts 21 are rotatably installed with a bearing seat 22. One side of each bearing seat 22 is fixedly connected to the inner wall of the groove 1.

[0024] When the two support arms 5 move toward each other, they slide inside the four transmission slots 20 via four connecting frames and four transmission pins 18, thereby causing the four clamping bars 19 to drive the four anti-slip pads 3 to rotate downwards along the four rotating shafts 21 to clamp the cable.

[0025] Each of the four locking components includes a support plate 12, which is fixedly installed in the middle of the four mounting slots 11. A rectangular rod 13 is fixedly installed in the middle of each of the four support plates 12. A locking block 14 is movably inserted into both sides of one end of each of the four plug-in rods 10. A rectangular slot 16 is opened on the side of the locking block 14 near the support plate 12. Both ends of the four rectangular rods 13 are respectively inserted into the corresponding rectangular slots 16. Springs 15 are sleeved on both ends of the surface of the four rectangular rods 13. Both ends of the springs 15 are respectively fixedly connected to the support plate 12 and the locking block 14.

[0026] As the two support arms 5 move toward each other, four plug rods 10 are inserted into the four plug holes 9. As the four plug rods 10 are inserted into the four plug holes 9, they all compress the locking blocks 14 and move them into the mounting groove 11 to retract. They slide along the surface of the rectangular rod 13 through the rectangular groove 16 and compress the spring 15. When the four plug rods 10 drive the locking blocks 14 through the plug holes 9, the spring force of the spring 15 pushes the locking blocks 14 to move outward and reset, thereby forming a locking engagement with the groove 1 to ensure the stability of the clamped cable.
