Description

Compact vacuum mooring device

Technical Field

The utility model relates to the technical field of mooring equipment, in particular to a compact vacuum mooring device.

Background

With the large-area popularization of the global automatic wharf, more urgent requirements are put on the automation of ship mooring, and the current mainstream ship automatic mooring system mainly comprises vacuum mooring. The vessel automatic mooring system has the following advantages over conventional line mooring. Firstly, it improves the security and reduces the risks of human errors and misoperation. The automation technology can accurately calculate and control the tension and length of the mooring rope, ensure the firm and safe connection between the ship and the wharf, and reduce the potential danger. Secondly, the automatic mooring system improves the working efficiency, realizes quick and accurate mooring operation, and saves time and energy cost. Compared with the traditional manual mooring, the automatic system can enable the ship to approach the wharf faster, so that the cargo loading and unloading speed is increased, and the port throughput is improved. In addition, the automatic mooring system also reduces labor cost and reduces the demand for human resources. While conventional mooring requires a significant amount of crew and quay personnel to engage, automatic mooring systems can reduce or even eliminate the need for on-site personnel to engage. Finally, the automatic mooring system can be adapted to harsh environments, and can better address challenges in harsh weather conditions, such as high winds, high waves, or harsh water conditions. The automatic mooring control system can adjust the suction and damping of the mooring device in real time according to the environmental change, and ensures stable connection between the ship and the wharf. Overall, the vessel automatic mooring system has advantages of improving safety, improving efficiency, reducing cost, and adapting to severe environmental conditions. These advantages have led to an increasing emphasis and adoption of automatic mooring systems in the modern marine and harbour industries.

The power mechanism is arranged on the fixed part 4 and comprises a front-back movement module, an up-down movement module and a left-right movement module;

In one embodiment, the adsorption mechanism comprises an adsorption bracket 11 and a sucker assembly 6, and the adsorption bracket 11 is connected with the power mechanism and the sucker assembly 6.

Specifically, as shown in fig. 2, one end of the power mechanism is fixed on the fixed part 4 of the support 2, the other end is connected with one side of the adsorption bracket 11 in the adsorption mechanism, and the other side of the adsorption bracket 11 is connected with the sucker assembly 6.

In one embodiment, as shown in fig. 2 and 4, the rail mechanism includes a vertical rail 9 and a lateral rail 10, the vertical rail 9 and the lateral rail 10 are mounted on the suction bracket 11, and the suction bracket 11 moves up and down on the vertical rail 9 and moves left and right on the lateral rail 10.

In particular, the rails may provide smooth movement, reduce vibrations and shocks, and may be designed according to different application requirements, not limited to the vertical rails 9 and the lateral rails 10, to achieve various trajectories and movement patterns.

In one embodiment, the vertical rail 9 is provided with a movement assembly of 600mm movement travel and the lateral rail 10 is provided with a movement assembly of 800mm movement travel.

In one embodiment, the back and forth movement module comprises a telescopic oil cylinder 5, the up and down movement module comprises a first oil cylinder, and the left and right movement module comprises a second oil cylinder;

The telescopic first oil cylinder end is connected with the adsorption bracket 11, and the other end is connected with the fixed part 4;

The first cylinder and the second cylinder are fixed on the adsorption bracket 11.

Specifically, the power mechanism is provided with three oil cylinders, and the three oil cylinders respectively correspond to the front-back movement, the left-right movement and the up-down movement. The power mechanism can drive the adsorption mechanism to move, so that the rubber sucker can be automatically or manually adjusted to adapt to environmental changes such as sea waves, tides and the like.

Still further, one quay 3 may be provided with 4 to 8 vacuum moorings, and when the vessel is docked, a plurality of rubber suction cups 8 will be used to suck the vessel surface. When the ship is changed in height with the tide level, the rubber suction cups 8 can realize a moving stroke of 600mm on the vertical rail 9, and when the rubber suction cups 8 reach 70% of the moving stroke during the moving process of the vertical rail 9, half of the rubber suction cups 8 automatically perform a pressure relief operation, compress the rubber suction cups 8 to a preset position, then move up and down, reposition to a central position and then stretch again to be firmly adsorbed on the side wall of the ship. The remaining half of the rubber suction cups 8 will then also perform the corresponding actions according to the same procedure as before. This operation aims to ensure stable mooring of the rubber suction cups 8 and to maintain the performance of the system, both to achieve accurate control of the position and direction of the vessel, while ensuring that the vessel does not lose stable mooring due to external factors. The rubber suction disc 8 can have a movement stroke of 800mm on the transverse track 10, and the position of the ship heading can be passively or actively adjusted through a power mechanism. The power mechanism is provided with the oil cylinder, the oil cylinder can ensure that the rubber sucker 8 is not influenced by the tide level, the track mechanism can limit the moving range of the rubber sucker 8, the moving stroke of the rubber sucker 8 in the up-down left-right direction can not be exceeded, and the safe mooring of the ship is ensured.

When the ship moves forwards, backwards, leftwards and rightwards along with the stormy waves, the oil cylinder arranged on the rubber sucker 8 in the direction can generate a certain damping force, so that the movement and the shaking of the ship are reduced. When the external force applied to the ship is too large and exceeds the adsorption force of 20 tons/platform, the rubber suction cup 8 can be automatically detached, so that the safety of equipment and the foundation of the wharf 3 is ensured.

In one embodiment, as shown in fig. 3, the adsorption bracket 11 is provided with a splayed arm 1, and the splayed arm 1 is connected with the power mechanism and the adsorption mechanism.

In particular, once the target vessel is on its own or is propped against the shore with the aid of a tug, the operator in the remote control room or on the shore can start the device. During this process, the suction cup assembly 6 will follow the extension of the splayed arm 1, bringing the rubber suction cup 8 slightly closer to the side wall of the vessel. Once the rubber suction cups 8 are in close contact with the side walls of the vessel, the compact vacuum mooring device is operated to ensure that the rubber suction cups 8 are tightly sucked onto the vessel, generating a lateral mooring force of not less than 20 tons/station to reliably secure the vessel firmly on shore. At this time, the vessel can safely perform cargo handling operations, while conventional mooring lines can be additionally used to increase mooring safety. This procedure ensures the safety of the secure berthing of the vessel and the handling of the cargo.

In one embodiment, as shown in fig. 2, a rotation shaft 7 is disposed between the suction cup assembly 6 and the suction bracket 11.

In particular, the rotating shaft 7 is used to transmit rotational motion and torque, and the rotating shaft 7 can transmit torque more efficiently while taking up less space than conventional transmission means such as belt transmission or chain transmission.

In one embodiment, the suction cup assembly 6 is provided with a rubber suction cup 8, the rubber suction cup 8 being used for sucking a ship.

The telescopic oil cylinder 5 comprises a first hydraulic component, the first oil cylinder comprises a second hydraulic component and the second oil cylinder comprises a third hydraulic component;

In one embodiment, the telescopic ram 5, the first ram and the second ram comprise hydraulic assemblies, and the suction cup assembly 6 is provided with a modular frame in which the hydraulic assemblies are mounted.

In particular, the modular design provides multiple advantages for the hydraulic assembly. First, the system can be customized and expanded according to specific requirements to meet the requirements of various applications. In addition, maintenance of the modular system becomes simpler and more convenient, and only the affected modules need to be replaced when in fault or upgrade, without changing the whole system, which reduces time and cost overhead. The modules are independent in operation, the reliability of the system is improved, and the fault of one module cannot affect the whole system. Finally, the modular design provides the system with a quick response capability that can quickly accommodate performance changes or new functional requirements, and is easily integrated with other control systems, including automated control and sensor systems. These characteristics make the modular hydraulic system a versatile, efficient and maintainable solution.

In one embodiment, the support 2 is connected to the quay 3 by means of anchor bolts.

In particular, the anchor bolts are a common foundation fixing method, and the anchor bolts can be used to firmly fix the structure on the ground or foundation, provide stable support, and prevent shaking or displacement of the structure. The compact vacuum mooring is thus mounted on the quay 3 rim by means of anchor bolts. A plurality of compact vacuum moorings can be installed on one dock, the number of the compact vacuum moorings can be flexibly configured according to the size and spacing requirements of a target ship, and generally, four to eight compact vacuum moorings can be selectively configured and installed on the dock 3.

Working principle: first, the device is provided with a powerful suction cup, the suction of which can be up to 20 tons. The sucker has three degrees of freedom, namely up and down, left and right, front and back, and each direction is provided with a corresponding oil cylinder, so that a certain movement travel range is allowed. The function of these cylinders is to achieve active adsorption and passive damping, especially on the side walls of the vessel. By arranging a plurality of devices on the wharf, automatic mooring of large ships can be realized, and shaking and vibration possibly occurring during mooring are reduced.

Second, the device takes advantage of the unique characteristics of the splayed arm 1, significantly simplifying the need for an external retraction mechanism. The overall dimensions of the device are thus 3.5 m x 1.8 m x 2.1 m, and in particular the installation width on shore is only 1.1 m, which makes it very suitable for most existing container terminals. In addition, due to the low overall height, the device can be firmly installed by only arranging a plurality of foundation bolts on the wharf without additional special reinforcement work.

Finally, the hydraulic components of the apparatus are arranged beside the suction cup apparatus in a modular manner, thus forming a complete vacuum mooring. This modular design facilitates maintenance and upgrades of the system.

The utility model has the following beneficial effects:
