Description

Technical Field

[0001] This utility model relates to the field of ship mooring technology, and in particular to a rapid mooring device for automatic berthing and unberthing of ships. Background Technology

[0002] Currently, most ship rapid release equipment adopts a configuration where the hook head and hook body are rotatably connected. The fixing of the cable and the release of the hook are mainly achieved by the following method: the rotatable connection between the hook head and the hook body is fastened by a locking mechanism, so that the hook head and the hook body are kept in a relatively fixed closed state, thereby restraining the ship's cable inside the hook body; when it is necessary to release the cable, the rotatable connection is unlocked, and the hook head is driven to rotate around the pivot at a certain angle to open the hook mouth. The cable slips out from the open hook mouth under its own tension or the action of external force, completing the release action.

[0003] However, the above-mentioned technical solutions have the following technical problems in practical applications: First, when the mooring line is moored, it will generate a continuous and large tensile load on the release hook. This tension will directly act on the rotating connection in the fixed state, causing the shaft, bearing and locking components to bear significant shear force and alternating stress, which will accelerate the wear and fatigue failure of the rotating pair and significantly shorten the service life of the rotating connection. Second, in order to prevent the mooring line from accidentally slipping off the hook due to wind, waves and vibration during the mooring period, the existing devices generally add anti-accidental release limit components (such as pins, baffles, etc.). However, such components need to be manually operated on-site to release the limit in emergency release, which increases the operation steps and time delay, making it difficult to meet the use requirements of rapid release in emergency situations and reducing the release response efficiency. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this utility model provides a device for automatic berthing and rapid mooring release of ships.

[0005] The technical solution of this utility model is implemented as follows: A rapid mooring release device for automatic berthing and unberthing of ships includes a mounting base and a mooring release mechanism. The mooring release mechanism is disposed on the side of the mounting base and includes a mooring release hook and a cylinder for driving the mooring release hook to rotate. The side of the mounting base is provided with a limiting member for limiting the mooring release hook.

[0006] Preferably, the cable release hook is mounted on the side of the mounting base via a fixed base, and one end of the cable release hook is rotatably connected to the fixed base.

[0007] Preferably, the unmooring hook is integrally formed, and the hook shank of the unmooring hook is rotatably connected to the fixed base, and the unmooring hook rotates up and down along the rotatable connection.

[0008] Preferably, the cylinder is inclinedly disposed on the side of the mounting base and below the fixed base, and the extended end of the cylinder is fixedly connected to the back of the release hook.

[0009] Preferably, the limiting member is disposed above the fixed base. The limiting member includes a mounting part and a limiting part. The limiting part is parallel to the side of the mounting base, and the mounting base has a limiting hole that is adapted to the tip of the cable release hook.

[0010] Preferably, the limiting hole is located at the upward rotation trajectory of the unhooking hook, and the hook tip rotates upward and passes through the limiting hole for fixation.

[0011] Preferably, the mounting base is also provided with a control mechanism on its side. The control mechanism includes several control buttons. The cylinder is electrically connected to the control mechanism, and the control buttons are used to control the cylinder to extend or retract.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-3 This utility model is a quick unmooring device for automatic berthing and unberthing of ships, including a mounting base 1 and an unmooring mechanism 2. The unmooring mechanism 2 is located on the side of the mounting base 1. The unmooring mechanism 2 includes an unmooring hook 3 and a cylinder 4 for driving the unmooring hook 3 to rotate. The side of the mounting base 1 is provided with a limiting member 5 for limiting the unmooring hook 3.

[0017] Specifically, the unmooring hook 3 is mounted on the side of the mounting base 1 via a fixing seat 6, and one end of the unmooring hook 3 is rotatably connected to the fixing seat 6; the unmooring hook 3 is integrally formed, and the hook handle 301 of the unmooring hook 3 is rotatably connected to the fixing seat 6, and the unmooring hook 3 rotates up and down along the rotatable connection.

[0018] In this embodiment, the unhooking hook 3 is an integral component forged and tempered and galvanized. Its hook shank 301 forms a rotating pair with the fixing seat 6 through a pin. The fixing seat 6 is welded to the side of the mounting seat 1.

[0019] Furthermore, the cylinder 4 is inclinedly disposed on the side of the mounting base 1 and below the fixed base 6, and the extended end of the cylinder 4 is fixedly connected to the hook back 302 of the release hook 3.

[0020] In this embodiment, the cylinder 4 is a double-acting single-rod type. The cylinder 4 is arranged at a 30° angle to the horizontal plane on the side below the fixed seat 6. The tail of the cylinder body is fixed to the side of the mounting seat 1 through a hinge seat. The end of the piston rod is hinged to the hook back 302 of the release hook 3 through a Y-type connector.

[0021] Furthermore, the limiting member 5 is disposed above the fixed base 6. The limiting member 5 includes a mounting part 501 and a limiting part 502. The limiting part 502 is parallel to the side of the mounting base 1, and the mounting base 1 is provided with a limiting hole 5021 that is adapted to the hook tip 303 of the cable release hook 3.

[0022] Specifically, the limiting hole 5021 is set at the upward rotation trajectory of the unhooking hook 3, and the hook tip 303 rotates upward and passes through the limiting hole 5021 for fixation.

[0023] In this embodiment, the limiting member 5 has an "L" shaped structure. Its mounting part 501 is fixed to the top of the fixing base 6 by bolts, and the limiting part 502 is parallel to the side of the mounting base 1. A limiting hole 5021 is opened in the center of the limiting part 502. The hole is oblong, and its center is located on the trajectory line of the hook tip 303 when the release hook 3 rotates upward.

[0024] Furthermore, the side of the mounting base 1 is also provided with a control mechanism 7, which includes several control buttons 8. The cylinder 4 is electrically connected to the control mechanism 7, and the control buttons 8 are used to control the cylinder 4 to extend and retract.

[0025] In this embodiment, the control mechanism 7 works in conjunction with the automatic unloading system. There are three control buttons 8: a reset button, a locking button, and a release button. These can be operated manually. When the reset button is pressed, the cylinder 4 extends, driving the release hook 3 to rotate to an initial position where the cable can be easily hooked in. The user can then hook the cable into the release hook 3. After pressing the locking button, the cylinder 4 continues to extend, driving the release hook 3 upwards, so that the hook tip 303 enters the limiting hole 5021 to limit the cable. For quick unhooking, pressing the release button retracts the cylinder 4, driving the release hook 3 downwards. The downward rotation of the release hook 3 allows the cable to slide off under its own weight, completing the quick unhooking. The release button can be controlled by the control mechanism 7. When the automatic unloading system issues a departure command, the control mechanism 7 controls the release button to automatically unload the cable.

[0026] The working principle of the automatic berthing and unberthing rapid mooring device for ships provided by this utility model is as follows: First, press the reset button to put the release hook 3 in the initial state. After the ship enters the port, the staff puts the cable into the release hook 3 and presses the locking button. The cylinder 4 extends and drives the release hook 3 to rotate upward, so that the hook tip 303 enters the limiting hole 5021 to limit the cable. At this time, the release can be performed without the operation of the staff. When the automatic departure system issues the departure command, the control mechanism 7 controls the release button to work, controls the cylinder 4 to retract, so that the release hook 3 rotates downward and the cable slides down under its own weight to release, thus completing the quick release.

[0027] This utility model provides a rapid unmooring device for automatic berthing and unberthing of ships. The device uses an integrally formed unmooring hook 3, which is driven by a cylinder 4 to rotate up and down to fix the ship's mooring line. When the cylinder 4 drives the unmooring hook 3 to rotate upward, the hook tip 303 passes through the limiting hole 5021 on the limiting member 5, forming a closed space to limit the mooring line and prevent it from accidentally unhooking. At the same time, the cylinder 4 can also provide a certain support for the unmooring hook 3, reduce the wear and fatigue of the rotating connection between the unmooring hook 3 and the fixed base 6, increase the service life of the rotating connection, and can also speed up the unhooking speed of the mooring line to a certain extent.
