Abstract

This vessel cradle consists of basic longitudinal (1) and cross beams, being connected by pins among them. At the corners of these beams, there are supports connected by pins and after them thinner supports are continued. On their body they have some drilled holes along the height in which the pins can be put, defining so the required height of the supporting plate which is connected by the pin on the top of the thinner support . The supports are connected to the basic beams (both cross and longitudinal ones) among other elements by strainers (21) , so that the complete cradle structure could be stiffened along its length and width. Basic part of the cradle can be extended by extension beams, depending on the vessel length for which the cradle is being prepared, as well as by additional supporting posts (11), supporting plates (19), strainers (21) and the like. The complete cradle can be disassembled and placed into a case and removed to the marine warehouse, which is not necessarily situated within the marine area, leaving so some precious free space for other purposes in the marine. The so disassembled and placed cradle in a case takes up to five times less space than when in function.

Description

CRADDLE FOR VESSELS

DESCRIPTION OF THE INVENTION

1. TECHNICAL FIELD

This invention refers to the cradle for vessels of assembly-disassembly type, with possibility of extension and developing fully, depending on the vessel length. Besides, when not necessary any more, it can be disassembled and completely placed in a case and removed from the marina. According to the International Patent Classification (IPC) it is categorized as: B 63 C 15/00; vessel placement on land other than dry docking.

2. TECHNICAL PROBLEM

The cradles known so far are rigid and firm for particular dimensions and size of the vessel, requiring more types and lengths of cradles, according to the size of vessels in the marine. In other words, for particular length of the vessel it is necessary to have an adequate and suitable cradle. That is why some improvised cradles with wooden beams and wedges, proved to be very unsafe and dangerous for operators and for the vessel itself in practice, as the vessel could be easily overturned on such cradles. Rigid and firm cradles and auxiliary outfit occupy significant space in the marine area, enabling so placement of more of vessels on the marine quay.

All the marines have been designed so to be protected against strong winds and consequently, they are always short of space and there is no enough place for great number of rigid cradles, not being in use due to their unsuitable length for all sizes of vessels.

A rigid, inflexible cradle could be removed only by crane or forklift into the marine corner if there is no need for the cradle any more. However, this type of cradle can be disassembled, its parts can be placed into the case and afterwards, that case can be brought to the marine warehouse or even removed outside the marine. When set into the case, the cradle takes up to five times less space than when in normal function.

3. STATE OF THE ART

There are still in use many improvised, rough-and ready cradles, consisting of wooden beams and wooden wedges, being interconnected by steel couplings and nails. They seem to be very unsafe for the operators and the vessel itself, as the vessel used to be turned over very often. Besides, setting of such a cradle used to take a considerable period of time. There are in use some rigid, firm cradles, aimed for particular size of vessels and consequently, many cradles of various sizes for all the lengths of vessels in the marine were necessary. Such a system of cradle structure used to cause the situation of many too many cradles out of use, laying around all over the marine, as the vessel in question was of other dimensions for example.

4. EXPLANATION OF THE NATURE OF THE INVENTION AND DESCRIPTION

The basic part of the cradle consists of main beam 1 to which the cross joint extension 4 is connected, used for connection of side beams 2 and 3 with strainer 21. To the basic beam 1 at both ends, cross joint beam 5 is continued, fixed with cross pin 9. In the same manner, to the basic beam I₅ gets tied the cross beam of the basic structure and extension 6 with pin 9, Figures 1 and 2.

To the cross joint beam 5, by the pin 10, shorter side support 11 is connected, in which the shorter plate bearer 17 shall be placed, Figures 1 and 2.

It can be seen in Figure 2 that the supporting plate 19 is connected by cross pin 20 to the shorter plate bearer 17. The shorter plate bearer 17 is adjustable per height, as it has more holes along its body, in which cross pin 15 can be set in.

Shorter side support 11 has an eye on it for straining stiffening 21, used as longitudinal stiffening to the side support 11, Figure 2.

The longer side support 13 is connected to the cross beam of the basic structure and extension 6, by cross pin 10. Into the longer side support 13, the longer plate bearer 18 shall be inserted, being interconnected by cross pin 15. Longer plate bearerlδ is connected to the supporting plate 19 with cross pin 20, Figures 1 and 2.

The basic part of the cradle can be easily extended (depending on the vessel length for which the cradle is being prepared), by an extension beam with straining stiffening 7 and 21, and extension beam 8. At the end they are connected with cross beam 5, by cross pin 9, Figure 1.

Longer side support 13 is tied with a longer strainer 14 to the cross joint beam 5, and/or by cross beam

- connection of basic structure and extension 6. Strainers 14 and 12 are used for side stiffening of the vessel, Figure 1.

Basic beam 1 has some extensions, on which the vessel keel shall be laid on the occasion of the vessel placement and removal to the cradle. The purpose of that extension is to prevent damaging of the vessel's keel due to the vessel weight, if the vessel is laid on the small surface, Figure 1.

Claims

PATENT CLAIMS

1. Vessel cradle is characterised that, basic part of the cradle makes the main beam (1), to which the cross joint extension(4) is connected, used for connection of side beams (2) and (3) with strainer (21), to the main beam (1) at both ends cross joint beam is continued (5), connected with cross pin (9). In the same manner, to the main / basic beam (1), cross beam of basic structure and extension (6) with pin (9), is connected Figure 1.

2. Vessel cradle is characterised that according to the patent claim 1, to the cross joint beam (5) by pin (10) is connected the shorter side support (11), in which the shorter bearer / girder (17) shall be put, to which the supporting plate (19) shall be connected by cross pin (20) Figures 1 and 2.

3. Vessel cradle is characterised that according to the patent claim 2, by the fact that the shorter girder / bearer (17) is adjustable per height, since on its body along the height it has more holes suitable for insertion of the pin (15), Figure 2.

4. Vessel cradle is characterised that due to the fact that the shorter side support (11) has an eye to which straining stiffening gets hooked (21), serving as longitudinal stiffening to the shorter side support (11), Figure 3.

Vessel cradle is characterised that another feature of the vessel cradle is that the basic part of the cradle can be extended (depending on the vessel length for which the cradle is prepared), by extension beam with straining stiffening (7) and (21), and continuing beam (8), to which they are connected with cross beam (5), by cross pin (9), Figure 1.

6. Vessel cradle is characterised that according to the patent claim 5, the longer side support (13) is connected with the longer strainer (14) to the cross joint beam (5), and/or by cross beam - connection of basic structure and extension (6), where strainers (14) and (12) are used for side stiffening of the vessel., Figure 1.
