Description

Technical Field

[0001] This utility model relates to the field of containerized davit technology, specifically a containerized davit device. Background Technology

[0002] A davit is a device installed on a ship for lifting and maneuvering davits. It serves functions such as lifesaving and cargo transport, and is one of the important pieces of equipment for ship safety and operation. A davit is a small boat on a ship used for purposes such as lifesaving, transporting personnel or cargo.

[0003] Currently, existing container-type davits typically involve installing the davit inside a shipping container. The container is opened for lifting operations. However, because the davit is installed inside the container, which is constantly exposed to a humid environment, it is prone to corrosion. Furthermore, the davit is fixed to the container by welding or bolts, making container replacement difficult and hindering easy separation. Additionally, the limited space inside the container makes operation and maintenance inconvenient, resulting in a lack of operational and maintenance space. Utility Model Content

[0025] Specifically, a container body 7 is set on each side of the lower container plate 1, the slider 5 is located in the middle of the limiting block 3, when the davit is not in use, the container body 7 completely covers the davit, the movable wheel 13 is located at the lower edge of the container body 7, the movable wheel 13 is in contact with the ship, and there is a gap between the lower part of the container body 7 and the ship.

[0026] Please refer to Figure 1. Figures 3 to 5 The lower part of the connecting base 4 is attached to the lower box plate 1, the slide groove 14 is closely fitted with the slider 5, the cross-section of the slider 5 is T-shaped, and the rear part of the slider 5 is fixedly connected to the limit block 3.

[0027] Specifically, the slide 14 is connected to the slider 5, and the limiting block 3 restricts the lateral movement of the connecting base 4.

[0028] Please refer to Figure 1. Figures 3 to 5The limiting groove 15 extends to the inner side of the limiting block 3, and the fixing block 8 is T-shaped. The end of the limiting groove 15 is closely fitted with the fixing block 8.

[0029] Specifically, the limiting groove 15 is connected to the fixing block 8 to restrict the longitudinal movement of the connecting base 4.

[0030] Please refer to Figure 1. Figures 3 to 5 A limiting screw 11 is fixedly connected to the upper part of the lower box plate 1. A fixing block 8 is sleeved on the limiting screw 11. A connecting nut 9 is threadedly connected to one side of the limiting screw 11. The lower part of the connecting nut 9 is in contact with the fixing block 8.

[0031] Specifically, the limiting screw 11 passes through the fixing block 8, the lower part of the fixing block 8 is in contact with the lower box plate 1, and the connecting nut 9 is provided with an anti-loosening structure inside.

[0032] Please refer to Figure 1. Figure 3 , Figure 5 The fixed end of the electric telescopic rod 10 is connected to the limiting block 3, and the movable end of the electric telescopic rod 10 is fixedly connected to the box body 7. The inner side of the box body 7 is fixedly connected to the connecting rod 16, and the outer side of the connecting rod 16 is slidably connected to the lower box plate 1.

[0033] Specifically, the moving length of the connecting rod 16 is consistent with the extension length of the electric telescopic rod 10. The electric telescopic rod 10 is a multi-segment telescopic rod. A sealing structure is provided between the lower box plate 1 and the box body 7, and a sealing strip is provided at the connection between the two boxes 7.

[0034] Please refer to Figure 1. Figure 3 The upper part of the connecting block 6 is connected to the davit body 12 via a rotating motor. The davit body includes a hook, a traction rope, a winch-type traction structure, and an integrated electrical control box. The traction rope is wound around the winch and driven by the control structure.

[0035] Specifically, when the davit main body 12 is not in use, it rotates and retracts into the container. The control structure controls the davit main body 12, and the electric telescopic boom 10 is also controlled through the davit main body 12.

[0036] During use, the container is installed on the ship for lifting small vessels. However, the container is subject to external influences over a long period of time, which can lead to corrosion and damage, requiring replacement. Replacement involves opening the container and separating it from the davit. To separate the container from the davit, the sliding groove 14 at the bottom of the connecting base 4 is separated from the slider 5, thus separating the davit from the container. During installation, the slider 5 is separated from the sliding groove 14, connecting the container to the davit. The design of the connecting base 4, slider 5, and sliding groove 14 facilitates the connection between the davit and the container. After replacement, the fixing block 8 is placed in the limiting groove 15 to secure the connection between the connecting base 4 and the lower box plate 1. The fixing block 8 is fitted onto the limiting screw 11 and secured with the connecting nut 9. Through the coordinated design of the limiting groove 15, fixing block 8, limiting screw 11, and connecting nut 9, the davit and container can be fixedly connected during use, enabling quick assembly and disassembly and achieving convenient separation of the davit and the container.

[0037] When performing extensive repairs or operations, the container door 2 is opened, and the container body 7 is entered. The electric telescopic rod 10 is activated via the control structure of the davit main body 12 to extend the container. The electric telescopic rod 10's wires are connected to the control structure, and it pushes the container body 7 outwards, thus opening the container and allowing for more extensive repairs or operations. The electric telescopic rod 10 effectively pushes the container body 7 to both sides. When the container body 7 moves, the connecting rod 16 is inserted into the lower container panel 1 to guide its movement. The casters 13 increase the efficiency of the container body's movement and prevent friction between the container body 7 and the ground. The combined use of the connecting rod 16 and the casters 13 facilitates the movement of the container body 7 during use, thereby increasing the container's operational space and achieving the goal of increasing the container's operating and maintenance space.
