Description

Technical Field

[0001] This invention relates to the field of marine technology, and more specifically to a stop and anchor device suitable for vertical anchor deployment and retraction. Background Technology

[0002] With the increasing application of intelligent and integrated technologies in ship design and manufacturing, the use of unmanned operation technology is also becoming more widespread. The intelligentization of electromechanical equipment not only greatly saves manpower but also improves the integration and reliability of various ship systems. As one of the most important systems on a ship, the anchoring system plays an irreplaceable role in ship safety. To achieve unmanned anchoring systems, it is necessary to solve the problem of replacing manual operation with automatic operation of key anchoring devices. The anchor catcher is one of the main devices in the anchoring system. It is a device used to hold the anchor chain in place to prevent the anchor from swaying when the ship is sailing or docked. Currently, commonly used anchor catchers use a steel wire rope threaded through the anchor chain and secured to the mooring post. The standard (CB / T 877-2011) anchor catcher cannot achieve automatic release without human intervention. Compared to the standard (CB / T 877-2011) anchor catcher, this invention changes the original anchor catcher's locking mechanism to achieve programmed and automated locking of vertically moving anchor chains. It uses a chain stop tongue to stop and limit the anchor chain links in place. On this basis, a multi-link motion mechanism, drive motor, and power supply are set up. To enable emergency release in the event of a power outage, a manual release wedge can be temporarily installed on the multi-link motion mechanism. Summary of the Invention

[0003] To address the aforementioned deficiencies in existing technologies, a stop and anchor device suitable for vertical anchor deployment and retrieval is provided. This device enables automated and unmanned operation of locking or releasing the anchor chain under normal power supply conditions. In the event of a complete power failure, the chain stop tongue can be safely and reliably moved by striking the manually released wedge to complete emergency release. This can be coordinated with the anchor winch manual brake to complete manual emergency anchoring.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1-2 As shown, the present invention provides a stop and anchor device 9 suitable for vertical anchor deployment and retraction, including a bracket assembly 1, a transmission assembly 2, a power unit 3, and a chain stop tongue assembly 4. The bracket assembly is fixed on an external base 5, and a set of inclined sliding grooves 6 are provided on the bracket assembly. The power unit and the chain stop tongue assembly are respectively located between the bracket assembly and the transmission assembly.

[0027] The transmission assembly includes a drive pair 2-1, a connecting rod 2-2, a sliding pair 2-3, and a movable shaft 2-4, all hinged together in sequence. The ends of the drive pair, connecting rod, and sliding pair are hinged together in sequence. The other end of the drive pair is hinged to the support assembly via the shaft, with the hinge point between the drive pair and the support assembly located between an inclined groove and the connecting rod. The other end of the sliding pair has a regular groove, through which the movable shaft passes and slides. The regular groove on the sliding pair ensures that the movable shaft moves smoothly along a pre-set path during movement, preventing it from jamming or locking up. The two ends of the power assembly are located between the support assembly and the drive pair, respectively, and are hinged to both via shafts. A chain stop tongue assembly is located between the support assembly and the movable shaft, hinged to both. The chain stop tongue assembly is hinged to the support assembly via a shaft and to the movable shaft. By moving the movable pivot within the inclined groove, the chain stop tongue assembly and the anchor chain 7 that has been stored in place can be in a locked state or a disengaged state.

[0028] In this embodiment, a sliding movable shaft is indirectly driven by a power unit to slide within an inclined chute and a regular chute, thereby switching the connection state between the chain stop tongue assembly and the external locking anchor chain between a locked state and a disengaged state.

[0029] Furthermore, in the embodiment shown in the figure, the lower end of the inclined slide is close to the chain stop tongue assembly, and the higher end of the inclined slide is close to the connecting rod; the drive pair is located at the upper end of the sliding pair, with the lower end of the drive pair close to the chain stop tongue assembly and the higher end of the drive pair close to the connecting rod. The power unit controls the rotation of the drive pair, causing the connecting rod to press against the sliding pair, making the sliding pair move away from the inclined slide, thereby moving the sliding pair from the upper left end to the lower right end of the inclined slide. When the transmission assembly is located at the upper left end of the inclined slide, the chain stop tongue assembly and the external locking anchor chain are in a locked state; when the transmission assembly is located at the lower right end of the inclined slide, the chain stop tongue assembly and the external locking anchor chain are in a disengaged state.

[0030] In some of the above embodiments, a detachable manually release block 8 is also included. The manually release block is mounted on the connecting rod, and the manually release block and the connecting rod are arranged parallel to each other. The manually release block has a hammering surface (see hammering direction F in the figure), and the hammering surface is arranged close to the drive pair. In the event of a power failure on the ship, the manually release block is installed, and the force indirectly applied to the sliding pair by the power unit is replaced by striking the manually release block with a hammer-like tool, thereby switching the state between the chain stop tongue assembly and the external locking anchor chain from the locked state to the disengaged state. The manually release wedge block can be left uninstalled under normal circumstances, and is installed on the connecting rod when manual emergency release is required.

[0031] Preferably, one end of the manually detachable block is provided with a slot, and the other end is provided with a hammering surface for the hammer; a protruding card is fixed on the side of the connecting rod, the card and the connecting rod are arranged in parallel, and the thickness of the card and the size of the slot are matched; the manually detachable block is installed on the transmission assembly through the matching connection of the card and the slot.

[0032] Specifically, the support assembly includes a wall frame 1-1, a support 1-2, and a load-bearing member 1-3. The wall frame consists of two parallel panels vertically fixed to the support, with inclined sliding grooves positioned at the same locations on both panels. The hinge between the drive pair and the support assembly is located on the wall frame. The support is fixed between the wall frames, and the hinge between the power unit and the support assembly is located on the support. The load-bearing member is fixed in the middle of the support, and the hinge between the chain stop tongue assembly and the support assembly is located on the load-bearing member. In the embodiment shown in the figure, the hinges between the load-bearing member and the power unit and the support assembly are located on two opposite surfaces of the support.

[0033] Specifically, the chain stop tongue assembly includes a rotating joint 4-1 and a chain stop tongue 4-2. One end of the chain stop tongue is provided with a locking tongue for locking the external anchor chain. One end of the rotating joint is hinged to the bracket assembly via a rotating shaft, and the other end is hinged to the middle of the chain stop tongue. The end of the chain stop tongue away from the locking tongue is hinged to the movable rotating shaft. In the embodiment shown in the figure, the power unit drives the movable rotating shaft to move along the inclined slide, indirectly driving the locking tongue end of the chain stop tongue to lock or release the external anchor chain.

[0034] Specifically, the power unit includes a piston rod 3-1, an electric motor 3-2, and a power supply 3-3. The piston rod is located between the support assembly and the drive unit; the electric motor and power supply are located on the piston rod and are interconnected. The starting end of the piston rod's telescopic column is connected to the power supply of the device's electrical control assembly and the electric motor. During anchoring operations, the electric motor drives the telescopic column in the piston rod to move. When the chain stop tongue retracts into place, the electric motor triggers a stop signal, the braking device in the electric motor engages, and the telescopic column in the piston rod stops moving.

[0035] Working principle and process of this invention:

[0036] This invention utilizes the design of a support assembly, a transmission assembly, a power unit, and a chain stop tongue assembly. The power unit drives the transmission assembly, which in turn drives the chain stop tongue assembly, enabling unmanned operation of locking or releasing the anchor chain. Furthermore, the transmission assembly is configured as a drive pair, a connecting rod, a sliding pair, and a movable shaft. A detachable manual release block is designed on the connecting rod to solve the problem of manually releasing the anchor chain in the event of a power outage. By striking the manual release wedge and combining it with the manual brake of the anchor winch, a manual emergency anchoring function is achieved in the event of a power outage.

[0037] During anchoring operations, the electric motor drives the telescopic column in the piston rod to extend. The telescopic column controls the downward rotation of the drive pair, indirectly transmitting the rotational torque through the connecting rod, causing the sliding pair to move away from the inclined chute. The sliding pair drives the movable shaft to move along the inclined chute in the upper left direction (upper left direction in the figure), causing the chain stop tongue to disengage from the locked state and separate from the locked anchor chain. When the movable shaft reaches the end of the inclined chute, the motor braking device intervenes, the telescopic column in the piston rod stops extending, the chain stop tongue is fully retracted, and the anchor chain release operation is completed.

[0038] The process of locking the anchor chain with the chain stop tongue is the reverse of the above process.

[0039] In the event of a ship's power failure, when emergency anchoring is required, such as Figure 3-5 As shown, first install the manual release block; then, tap the manual release wedge downwards. The wedge will move downwards upon impact (replacing the force of the power component), thereby pushing the sliding pair to move the movable shaft along the inclined chute to the upper left. The sliding pair causes the locking tongue end of the chain stop to disengage from the anchor chain. When the movable shaft reaches the upper left end of the inclined chute, the chain stop is fully retracted, and the anchor chain release operation is complete. Emergency anchoring can then be performed by operating the anchor winch's manual brake.

[0040] The above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent changes made in accordance with the claims of the present invention shall still fall within the protection scope of the present invention.
