Description

Technical Field

[0001] This utility model relates to the field of dredging engineering technology, and in particular to a device for automatic adjustment of cable trays for crossing ships. Background Technology

[0002] In recent years, the demand for dredging of rivers, lakes, and reservoirs has been increasing. During the dredging process, construction vessels typically use diesel generators or shore power for power. Considering that vessels use land-based electricity, and in order to save space on the vessels, it is necessary to make the most of the vessel's own cabins. Diesel generator sets will no longer be installed on the vessels as a power source, which aligns with the requirements of reducing carbon emissions and truly achieving green, energy-saving, and environmentally friendly practices.

[0003] For the multiple vessels involved in dredging in Taihu Lake, none of them are self-propelled. When multiple vessels are stationary and working together, it is necessary to connect cables across the vessels by placing cable trays between them to lay the cables and provide power to the other vessels. However, as the draft of the vessels changes, the cables are prone to rapid wear and tear during use, posing a significant safety hazard.

[0004] Therefore, in order to ensure the safe use of cross-ship cables, it is essential to develop and manufacture a device that can reduce wear and tear on cross-ship cables. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a device for automatic adjustment of cable trays for cross-ship use. This device can automatically adjust the force on the cable trays according to the changes in the draft of the two ships, thereby ensuring the safe use of cross-ship cables.

[0006] This utility model is implemented as follows: a device for automatic adjustment of a cross-ship cable tray, which is installed between two ships and includes a cable tray, an automatic wire rope winding and unwinding device and a pressure monitoring system. The cable tray is used to support the laying of cross-ship cables. One end of the cable tray is hinged to the deck of one ship and the other end is attached to the deck of another ship.

[0007] The automatic wire rope winding and unwinding device includes a wire rope, a winch, and an A-frame. One end of the wire rope is connected to the winch, and the other end is connected to the non-fixed end of the cable tray. A pulley is installed at the top of the A-frame, and the wire rope is wound around the pulley. The winch and the A-frame are installed on a ship that is hinged to the cable tray.

[0008] The pressure monitoring system includes a pressure sensor and a signal feedback system. The pressure sensor is used to monitor the force on the wire rope and feed the signal back to the signal feedback system. The signal feedback system controls the automatic winding and unwinding of the wire rope based on the received signal.

[0009] In the above technical solution, preferably, the cable tray is hinged to a ship deck.

[0010] In the above technical solution, preferably, a ring is installed on the non-fixed end of the cable tray, and a hook is connected to the wire rope connected to the non-fixed end of the cable tray, with the hook connected to the ring.

[0011] In the above technical solution, preferably, the pressure sensor is located on the wire rope.

[0012] In the above technical solution, preferably, rollers are installed under the cable tray that is attached to the ship's deck.

[0013] When the draft of the two ships changes and a height difference is created, the pressure sensor reading changes and outputs a signal. The wire rope is automatically wound up and down by the winch, causing the cable tray to rotate with the hinge point until the pressure sensor reading reaches the pressure set value, so that the cable tray always stays close to the ship's deck where the freeboard is small.

[0014] The advantages and positive effects of this utility model are:

[0015] 1. The device for automatic adjustment of cross-ship cable trays of this utility model is used for laying cross-ship cables. Compared with other cable trays, by setting up a pressure detection system and an automatic wire rope winding and unwinding device, when the draft of the two ships changes and a height difference is generated, the pressure monitoring system acts as a wire rope tension detection device. When the detected pressure value deviates from the set pressure value, the signal feedback system feeds back the signal to the automatic wire rope winding and unwinding device. The automatic wire rope winding and unwinding device realizes the automatic winding and unwinding of the wire rope according to the feedback signal, thereby realizing the automatic adjustment of the cross-ship cable tray.

[0016] 2. This utility model enables two ships to automatically and safely connect according to changes in draft, maximizing the protection of the cross-ship cable from wear and tear. It effectively solves the problem of cable brackets failing to provide support due to changes in draft between the two ships, thus causing wear and tear on the cross-ship cable. It enables unmanned operation, effectively ensuring the safety of the cross-ship cable during use, and significantly improving safety performance. Attached Figure Description

[0024] Example

[0025] Please see Figures 1-3 This utility model provides a device for automatically adjusting a cable tray 2 for crossing ships. The device is installed between two ships to support the cable 1 crossing between them. When the drafts of the two ships change and a height difference occurs, the height of the cable tray 2 can be automatically adjusted to prevent cable wear. It includes a cable tray 2, an automatic wire rope winding and unwinding device, and a pressure monitoring system.

[0026] The cable bracket 2 is used to support the laying of the cross-ship cable 1. One end of the cable bracket 2 is hinged to a ship deck, and the other end is attached to another ship deck.

[0027] The automatic wire rope winding and unwinding device includes a wire rope 4, a winch 3, and an A-frame 9. The winch 3 is used to wind up and unwind the wire rope 4, which is used to pull the cable tray 2. The A-frame 9 supports the winding and unwinding of the wire rope 4. One end of the wire rope 4 is connected to the winch 3, and the other end is connected to the non-fixed end of the cable tray 2. A pulley 7 is installed at the top of the A-frame 9 to support the wire rope 4, which winds around the pulley 7. The winch 3 and the A-frame 9 are mounted on a ship that is hinged to the cable tray 2. In this embodiment, the winch 3 is mounted on the ship's deck, and the A-frame 9 is mounted on one side of the ship's side.

[0028] The pressure monitoring system includes a pressure sensor 5 and a signal feedback system. The pressure sensor 5 is used to monitor the force on the wire rope 4 and feed the signal back to the signal feedback system. The signal feedback system controls the automatic winding and unwinding of the wire rope 4 based on the received signal.

[0029] In a preferred embodiment, the cable tray 2 is hinged to a ship deck via a hinge 6. The hinge 6 mounts the cable tray 2 onto the ship deck. In this embodiment, two hinges 6 are provided to ensure smooth rotation.

[0030] In a preferred embodiment, a ring 8 is installed on the non-fixed end of the cable tray 2. The ring 8 is used to connect the wire rope 4 to the cable tray 2. A hook is connected to the wire rope 4 connected to the non-fixed end of the cable tray 2. The hook is connected to the ring 8 to facilitate the connection between the wire rope 4 and the cable tray 2.

[0031] In a preferred embodiment, the pressure sensor 5 is located on the wire rope 4 to monitor the force on the wire rope 4 in real time. Specifically, an FZTA type wire rope tension sensor can be used.

[0032] As a preferred embodiment, the cable tray 2, which is attached to the ship's deck, is equipped with rollers, allowing the non-fixed end of the cable tray 2 to slide freely.

[0033] In this invention, the cable tray 2 supports the laying of the cross-ship cable 1. One end is hinged to the relatively high ship deck via a hinge 6 to achieve height adjustment; the other end is connected to the relatively low ship deck via rollers, allowing free sliding. This end is also equipped with a ring 8 for fixing the steel wire rope 4. One end of the steel wire rope 4 is connected to a winch 3, and the other end is fixed to the non-fixed end of the cable tray 2, connected to the ring 8 via a hook. An A-frame 9 is installed on the side of the ship to support the winding and unwinding of the steel wire rope 4, automatically winding and unwinding according to feedback signals.

[0034] When the hull at the non-fixed end of cable bracket 2 has a deep draft, cable bracket 2 tilts downwards and is fully overlapped on the ship's deck by rollers. When this happens, the steel wire rope 4 experiences less force, and the pressure sensor 5 reading is lower than the set value. At this time, the steel wire rope 4 is automatically stretched to bring the reading back to the set value, and cable bracket 2 fits snugly against the ship's deck, with the ship's deck surface experiencing almost no force. When the hull at the non-fixed end of cable bracket 2 has a shallow draft, cable bracket 2 tilts upwards, and the pressure sensor 5 reading is brought to the set value using the same method.

[0035] The specific working principle of this utility model is as follows:

[0036] When the draft of the two ships changes and a height difference is created, the pressure sensor 5 sends a signal to the winch 3 to wind up and unwind the wire rope 4, so that the non-fixed end of the cable bracket 2 just overlaps the ship's deck surface, minimizing the stress on the ship's deck surface and maximizing the protection of the cross-ship cable 1 from wear, thus ensuring safe use.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
