Technical Field
[0001] This utility model relates to the field of segmented assembled cable tray technology, specifically a segmented assembled cable tray structure for ships. Background Technology
[0002] Segmented prefabricated cable trays are cable support systems that utilize standardized prefabricated components and are rapidly assembled on-site. In the marine industry, they are widely used as an efficient and flexible cable support solution. Their core advantages are: components are prefabricated in the factory, ensuring quality control; upon arrival at the shipyard, minimal welding and cutting are required, allowing for rapid assembly like "building blocks" with only bolts and other fasteners, significantly shortening the construction cycle and reducing the risk of on-site hot work. Addressing the limited and complex spaces of ships and the needs of later maintenance and retrofitting, their modular design allows for flexible layout adjustments to accommodate pipeline equipment routing and facilitates partial disassembly for cable expansion. Materials typically include corrosion-resistant galvanized steel or stainless steel to meet the stringent requirements of marine environments; the structural design balances strength and lightweight, effectively supporting the weight of various cables.
[0003] Existing cable tray structures are usually of fixed length, requiring cutting during installation, which is very troublesome. Moreover, most are connected by welding or bolts, which is inconvenient to disassemble and assemble. Furthermore, the cut sections may not be recyclable due to length issues, reducing the practicality of the device. In addition, there may be rough seas at sea, causing the ship to sway and adding centrifugal force to the cables, increasing the burden on the support and potentially reducing its lifespan. Utility Model Content
[0004] The purpose of this utility model is to provide a segmented prefabricated bridge structure for ships to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmented prefabricated bridge structure for ships, including a bridge plate and a lifting platform provided on the upper side of the bridge plate, an adjustable and convenient disassembly and assembly mechanism provided on the inner side of the bridge plate, and a buffer mechanism provided on the upper side of the bridge plate;
[0006] The adjustable and easy-to-assemble / disassemble mechanism includes a splicing plate that is slidably connected inside the bridge plate. Multiple lock boxes are located inside the splicing plate, with each lock box having a sliding plate slidably connected inside. A rotating cylinder is fixedly connected to the side of each sliding plate that is close to the other. Multiple limiting strips are fixedly connected inside each rotating cylinder. A spreading spring is fixedly connected between the inner walls of the lock boxes on the side where the sliding plates are close to each other. A screw is threadedly connected inside each lock box, and the screw is slidably connected inside the rotating cylinder. A rotating sleeve is fixedly connected to the end of each screw that is close to the other. Insert rods are slidably connected inside each of the rotating sleeves and lock boxes. A locking rod is fixedly connected to the side of each sliding plate that is far away from the other.
[0007] Preferably, each screw has a groove inside that mates with the limiting strip.
[0008] Preferably, each of the insertion rods is provided with a magnet that attracts the surface of the rotating sleeve.
[0009] Preferably, the diameter of the locking rod is the same as the diameter of the groove inside the bridge plate, and one side of the locking rod is provided with an inclined surface.
[0010] Preferably, the buffer mechanism includes a pressure relief cylinder, which is fixedly connected to the upper surface of the bridge plate. A piston plate is slidably connected inside the pressure relief cylinder, and a slide rod is fixedly connected to the upper surface of the piston plate. The platform is fixedly connected to the slide rod, and the slide rod is slidably connected to the pressure relief cylinder. A buffer spring is fixedly connected between the lower surface of the piston plate and the inner wall of the pressure relief cylinder. A pressure discharge cylinder is connected to the upper interior of the pressure relief cylinder. Multiple baffles are fixedly connected inside the pressure discharge cylinder. A pressure relief spring is fixedly connected to one side of each baffle. A top ball is fixedly connected to one end of the pressure relief spring and is located on the side close to the pressure relief cylinder. A back pressure port is connected to the upper interior of the pressure relief cylinder.
[0011] Preferably, the diameter of the top ball is larger than the inner diameter of the baffle and smaller than the outer diameter of the baffle.
[0012] Preferably, the back pressure port and the pressure discharge cylinder have the same internal diameter.
[0013] Compared with the prior art, this utility model provides a segmented prefabricated bridge structure for ships, which has the following advantages:
[0014] The adjustable and convenient assembly / disassembly mechanism is used for quick assembly and disassembly of cable trays. This mechanism uses alternating splicing of bridge plates and splicing plates, allowing users to freely adjust the connection position of the splicing plates and bridge plates and flexibly change their positions. This avoids the need to install multiple bolts or welds on both sides of the cable tray. The locking rod is used to limit the movement of both, so users do not need to cut the cable tray. At the same time, the screw and locking box can lock the locking rod with threads, and the insertion rod can provide additional limit on the rotation of the locking rod when needed, so that the connection of the cable tray can be stable. This eliminates the need for multiple bolts or welds to limit the movement of the cable tray, reducing the complexity of the connection and improving efficiency.
[0015] The buffer mechanism is used to provide support and cushioning for the device. When the cable tray experiences shaking or impact, the pressure relief cylinder is pulled down by the cable plate. The buffer spring and the air pressure inside the pressure relief cylinder provide buffer support for the cable plate and the cables inside the cable plate, so that the connection between the cable plate and the platform will not be rigidly restricted and thus cause fatigue fracture, increasing the service life of the cable tray.

[0026] This mechanism is used for quickly connecting bridge plate 1 and adjusting the splicing length of bridge plate 1.

The adjustable and easy-to-assemble / disassemble mechanism 3 includes a splicing plate 301, which is slidably connected inside the bridge plate 1.

Multiple limiting strips 305 are fixedly connected inside the rotating drum 304.

A screw 307 is threadedly connected inside the lock box 302. The screw 307 is slidably connected inside the rotating drum 304. A rotating sleeve 308 is fixedly connected to the end of the screw 307 that is close to it. Insert rods 309 are slidably connected inside the multiple rotating sleeves 308 and the lock box 302. A locking rod 310 is fixedly connected to the side of the slide plate 303 that is far away from it.
[0027] Furthermore, each screw 307 has a groove inside that mates with the limiting strip 305.
[0028] Furthermore, each of the insertion rods 309 is provided with a magnet that attracts the surface of the rotating sleeve 308.
[0029] Furthermore, the locking rod 310 has the same diameter as the internal groove diameter of the bridge plate 1, and a slope is provided on one side of the locking rod 310. Example
[0030] This mechanism provides cushioning for bridge plate 1, thus extending its lifespan. (See also...) Figure 1-5Furthermore, in conjunction with Embodiment 1, the buffer mechanism 4 includes a pressure relief cylinder 401, which is fixedly connected to the upper surface of the bridge plate 1. A piston plate 402 is slidably connected inside the pressure relief cylinder 401, and a slide rod 403 is fixedly connected to the upper surface of the piston plate 402. The platform 2 is fixedly connected to the slide rod 403, and the slide rod 403 is slidably connected to the pressure relief cylinder 401. A buffer spring 404 is fixedly connected between the lower surface of the piston plate 402 and the inner wall of the pressure relief cylinder 401. A pressure discharge cylinder 405 is connected to the upper interior of the pressure relief cylinder 401. Multiple baffles 406 are fixedly connected inside the pressure discharge cylinder 405. A pressure relief spring 407 is fixedly connected to one side of the baffle 406. A top ball 408 is fixedly connected to one end of the pressure relief spring 407. The top ball 408 is located on the side close to the pressure relief cylinder 401. A back pressure port 409 is connected to the upper interior of the pressure relief cylinder 401.
[0031] Furthermore, the diameter of the top ball 408 is set to be larger than the inner diameter of the baffle 406 and smaller than the outer diameter of the baffle 406.
[0032] Furthermore, the back pressure port 409 and the pressure discharge cylinder 405 have the same internal diameter.
[0033] In actual operation, when this device is used, the user inserts the splicing plate 301 into the bridge plate 1. At this time, the inclined surface of the locking rod 310 is in the same direction as the insertion of the splicing plate 301. When the locking rod 310 passes through the round hole on the bridge plate 1, the spring 306 is released, which pushes the sliding plate 303 to push the locking rod 310 out. The locking rod 310 slides out of the outer side of the bridge plate 1. Since the inclined surface of the locking rod 310 is in the same direction of movement as the splicing plate 301, the user can continue to push the splicing plate 301 to move. At this time, the round hole inside the bridge plate 1 will be pushed into the lock box 302 through the inclined surface of the locking rod 310, so as to facilitate free selection. The splicing length of the splicing plate 301 and the bridge plate 1 is selected. When the user needs to lock the splicing plate 301 and the bridge plate 1, the user can rotate the rotating sleeve 308. The rotating sleeve 308 drives the screw 307 to rotate. At the same time, when the screw 307 rotates, it drives the rotating cylinder 304 to rotate, so that the inclined surface of the locking rod 310 is opposite to the upper surface of the bridge plate 1. At this time, because the inclined surface of the locking rod 310 and the splicing plate 301 move in different directions, the round hole on the bridge plate 1 cannot push the locking rod 310 to extend and retract the spring 306. At the same time, the threaded connection between the screw 307 and the lock box 302 provides the locking rod 310 with To limit the movement, when the user needs to remove the splicing plate 301, the user can rotate the rotating sleeve 308 to align the inclined surface of the locking rod 310 with the moving direction of the splicing plate 301. However, ships are easily impacted by water currents, which may cause insufficient limiting of the screw 307. In this case, the user can choose to insert the insertion rod 309 into the lock box 302 to forcibly limit the locking rod 310. When the ship is impacted by ocean currents, the bridge plate 1 and its internal cables may generate centrifugal force due to the impact. At this time, the bridge plate 1 is affected by gravity and moves downward synchronously with the pressure relief cylinder 401. The reduced space inside the pressure relief cylinder 401 will cause the buffer spring 4 to... When the pressure is compressed, the air pressure inside the pressure relief cylinder 401 is also compressed and discharged through the pressure discharge cylinder 405 and the back pressure port 409. In turn, the air pressure and the support of the buffer spring 404 provide a buffer for the bridge plate 1, avoiding the impact of rigid connection. After the air pressure inside the pressure relief cylinder 401 is discharged, the centrifugal force of the bridge plate 1 is relieved. The buffer spring 404 drives the bridge plate 1 to reset, while the internal channel of the pressure discharge cylinder 405 is closed by the top ball 408. At this time, the air pressure inside the pressure relief cylinder 401 is replenished through the back pressure port 409, preventing the bridge plate 1 from shaking due to the influence of the buffer spring 404.
