PURPOSE:To enable the easy installation of a mariner yard at a restricted wharf by forming a lift frame bed with an upper and lower lift frame beds having a built-in stored boat receiver, and installing a gantry crane having a builtin lift device for the aforesaid beds in such a way as to be capable of free travel on rails. CONSTITUTION:A boat 20 moored alongside a wharf is stored on a stored boat receiver 15 built into the lower lift frame bed 12 of a lift frame bed 10. Then, the lower lift frame bed 12 is lifted to such height as equal to a level for the carriage of an empty storage compartment in a solid boat house 30 and the boat 20 is carried therein. Thereafter, a crane 30 travels on rails 41 laid on a foundation rack 50 and carries the lower lift frame bed 12 into the solid boat house 30. A similar process is further repeated, thereby stacking an upper lift frame bed 11 onto the lower lift frame bed.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a three-dimensional marina yard.

(Prior art) Recently, in addition to marine recreation, more active and sporty marine recreation such as yachting, motorboating, windsurfing, and diving has rapidly become popular, and it has become a new place for marine recreation.
The use of water bodies is becoming more diverse, dense and widespread.

In response to the spread and popularization of marine recreation, there has been a significant increase in the number of inexpensive and casual marinas with a high public nature. Maintenance of the marina is required. In addition, in response to the increasing need for long-term stay recreation, there is a need to develop marinas as the core of resort bases.

However, despite the development and spread of marine recreation, the supply of marinas is insufficient, and there are still many yachts and motorboats that cannot accommodate them.

In particular, when lifting and lowering motorboats and yachts, the intrusion of wave swells and the difference in tide levels have an effect, so there was no suitable marina yard that took these into account.

For example, a rail ramp system in which a slope rail is provided on the coast, the rail is built on the slope, and a winch is used as the main power is mainly used for lifting and lowering medium-sized motorboats.

Also, forklift type vehicles are used for lifting and lowering boats, transporting them on land, and storing them in multi-tiered boat sheds.

Traveling cranes, mobile cranes, and fixed cranes are used to lift and lower medium-sized and larger boats.

Furthermore, as shown in Fig. 8, for example, it is used as a total system by connecting to a rack and a three-dimensional boat shed, and is convenient for remodeling an empty warehouse overlooking a canal and for three-dimensional storage in a narrow space, but the equipment cost is high. It can be said that this is a facility that is expected to be installed only under special location conditions.

(Problems to be Solved by the Invention) The present invention provides a three-dimensional marina yard that can be easily installed on a narrow quay wall, doubles as a berth, allows people to carry out boats safely and reliably, and does not require any power source. This is what we provide.

(Means for Solving the Problem) The present invention constructs upper and lower lifting frames by erecting four struts diagonally on a hanging frame in which a storage boat cradle is installed. A three-dimensional boat shed that is removable by providing a fitting mechanism for supporting the load on the lower suspension frame at the joint where the supports of the upper suspension frame and the lower suspension frame come into contact with each other, and a storage space for the three-dimensional boat shed. This is a three-dimensional marina yard characterized by comprising a recessed crane which is disposed so as to be freely movable and which is equipped with an internal lifting device for the hanging frame.

Embodiments of the present invention will be described below with reference to the drawings.

2 has a cradle l5 therein for storing the storage boat 20, so that the size corresponds to the size of the boat.

FIG. 4 is an enlarged view of the three-dimensional boat shed of the present invention, and a
The section is shown in FIG.

That is, in the present invention, as shown in FIG.
The strut l3 of L and the strut I4 of the lower suspension frame 12 have a joint portion 25 that abuts each other, and a fitting mechanism, for example, welding a circumferential member 1B to the outer periphery of the lower end of the strut I3, forms a welded portion 1B. ing. Further, if necessary, a slope 17 is provided at the upper end of the support column 14 and the lower end of the circumscribing member 1B to facilitate contact and fitting between the support columns 13 and 14.

As mentioned above, the suspension frame in the present invention is a pair of upper and lower suspension frames, and each support 13. 14 are arranged diagonally, so when the hanging frames are stacked three-dimensionally, the load of the upper fabric frame 11 is supported by the supports 14 of the lower hanging frame 12. Further, in the hanging frame lO of the present invention, the upper and lower hanging frames can be freely attached to and detached from each other via the above-mentioned fitting mechanism, thereby forming a boat shed that also serves as a boat platform.

In the present invention, a three-dimensional boat shed 30 is constructed by arranging a plurality of the above-mentioned suspension frames 10-1 to 10-n as shown in FIG.

A plan view of the three-dimensional boat shed 30 is shown in FIG.

In the present invention, a recessed crane 40 is disposed in the three-dimensional boat shed 30 so as to be movable. The recessed crane 40 is shown in FIG.
As shown in the figure, it is supported by four legs with a vibrator truss claim structure and runs on a rail 4l. The rails 4l are installed on a foundation 50 constructed on a quay, and are arranged to form a storage space 51 of a three-dimensional boat shed, as shown in FIG. In addition, the gate-type crane 40 has a suspension frame lifting device 42, and uses a hydraulic motor (not shown) to move the boat 20 stored in the suspension frame lO.
Designed to raise and lower the desired height above the water surface.

That is, the lifting device 42 is attached to the main column 41 of the portal crane 40.
A rail 43 is provided, and a boat seat 45 is horizontally mounted between the main pillars and can be raised and lowered. Further, a second rail 46 extending to a level lower than the quay wall level is provided on the boat seat 45, and a triangular hanging body 44 is protruded so as to be able to rise and fall freely, and has a gripping device 47 for the support of the hanging frame l1.

The structure of the present invention is as described above, and the operation will be explained next.

The boat 20 that has moored itself to the quay is stored in the storage boat cradle l5. Since the storage boat cradle 15 is installed inside the upper and lower suspension frames,
The lifting frame lifting device 42 of the recessed crane 40 lifts the boat to a desired height, for example, the transportation height of an empty boat shed in the three-dimensional boat shed 30. As shown in FIG. 3, the recessed crane 40 has rails 4l arranged to form a storage space 5l.
The suspension frame is brought in by traversing or traveling, and this is repeated to stack the upper suspension frame on the lower suspension frame of the same size to form a three-dimensional boathouse.

The wheel stopper of the portal crane is attached to the rail 41 in order to position the upper suspension frame to be carried in three-dimensionally onto the lower suspension frame that has been carried in advance.
It is best to place it on the side.

The present invention allows the storage boat to be stored and carried in by simply obtaining information in advance and preparing several types of pairs of suspension frames depending on the size of the storage boat, and using the suspension frame as a three-dimensional boat shed that also serves as a boat platform.

In addition, the present invention uses hanging frames of the same standard size to form a three-dimensional boat shed using the fitting portions of the four leg supports.For example, in order to take out the boat 20-1 in FIG. 2 can be grabbed by a portal crane and moved to the storage space 51, and then moved together with the boat 20-1 by a concave crane.

In the experiment, the total length was 11.0 m and the total width was 3. [im, When storing a boat with a weight of 13 tons on a suspension frame of a vibrator truss frame structure with a four-point hoist, and transporting it using a concave crane with a four-legged support structure, the concave crane is used as a suspension platform lifting device. A hydraulic motor drive system is adopted, and a tire-wheel hydraulic motor drive is used as the traveling and traversing device of the recessed crane.

Hanging frame lifting speed 15m/s+In, horizontal, running speed 10m
It was possible to operate with /sin acceleration/deceleration mechanism.

The power source used a 30-150 horsepower diesel engine unit and did not require any other power source.

FIGS. 6 and 7 are schematic diagrams showing a comparison between an example of the present invention and a conventional example.

Figure 6 shows that when accommodating boats using the crane and forklift method, a total of 20 boats were accommodated, 18 boats in areas A and B and 11 boats in area C, taking into account the operation of the crane and forklift. On the other hand, in the example of the present invention, as shown in FIGS. 7(b) and 7(c), 95 boats were housed in a three-dimensional boathouse having the same area as that in FIG. 6.

(Effects of the Invention) The present invention provides a fitting mechanism on the supports of the upper and lower suspension frames, and
The lower suspension platform is also used as a boat platform to form a three-dimensional boat shed for loading boats, and a gate-type crane is used to carry out the lifting of the boat. Since it travels and crosses, it is suitable for three-dimensional marina yards that utilize narrow coastal LR walls, and has great industrial value.
