Description

Technical Field

[0001] The present invention relates to the technical field of ship equipment, and in particular, to a wave adaptive rescue boat retractable connection device. Background Art

[0002] The wave adaptive rescue boat can absorb and buffer the impact of waves on the hull, reduce the influence of waves on the rescue boat, and enable it to carry out rescue work stably and safely under high sea conditions. Usually, the rescue boat is stored on the rescue boat retractable device of the ship. When in use, it is connected to a cable through a connection device and hoisted and recovered by a davit. At present, the rescue boat connection device usually adopts a marine hook or a combination of a marine hook and a sling. However, such a connection device cannot adapt to the special cage-shaped hull of the wave adaptive rescue boat, so it cannot complete the work of connecting and releasing the wave adaptive rescue boat under sea state 5. Summary of the Invention

[0003] In view of the above-mentioned technical problem that the existing rescue boat retractable device does not adapt to the hull structure of the wave adaptive rescue boat, a wave adaptive rescue boat retractable connection device is provided. The connection device of the present invention can not only be installed on the cage-shaped hull of the wave adaptive rescue boat, but also safely release and recover the wave adaptive rescue boat under sea state 5.

The snap grooves are respectively clamped onto the three steel pipes and connected to the lug body through bolts to clamp the steel pipes of the hull.

[0013] Further, the snap cooperates with the lug body to limit the relative displacement between the hull and the snap - type lug in three directions, and completely fixes the snap - type lug on the hull.

[0014] Further, the side baffle and the bottom baffle are respectively vertically arranged on two adjacent sides of the lug base plate. The right - angle inner side formed at the connection between the side baffle and the lug base plate is connected by the snap and fixed by bolts. The right - angle inner side formed at the connection between the bottom baffle and the lug base plate is connected by the snap and fixed by bolts. The right - angle inner side formed at the connection between the side baffle and the bottom baffle is connected by the snap and fixed by bolts.

[0015] Further, the materials of the lug base plate, the side baffle and the bottom baffle all include Q235 ordinary carbon structural steel.

[0016] Further, the snap is processed by cutting, and the material includes Q235 ordinary carbon structural steel.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The wave - adaptive rescue boat retracting and connecting device provided by the present invention can adapt to the special hull structure of the wave - adaptive rescue boat and effectively release and recover the wave - adaptive rescue boat under sea state 5.

[0025] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0027] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary embodiments of the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for the sake of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary statements, these orientation words do not indicate and imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the protection scope of the present invention: the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0030] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0031] In addition, it should be noted that the use of words such as "first", "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above words have no special meanings. Therefore, they should not be construed as limiting the protection scope of the present invention.
