Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a lifting device for a gate crane of a three-dimensional boat yard.

(Prior art) Recently, in addition to marine recreation, more active and sporty marine recreations such as yachts, motor boats, windsurfing, diving, etc. have rapidly spread, and as a new marine recreation site, it has become more diverse. Therefore, dense and widespread use of water bodies is progressing.

In response to the popularization and popularization of marine recreation, there is a large increase in the number of public marinas that are inexpensive and easy to operate, but a complex of various facilities that can provide higher quality facilities and high-level services. Marina maintenance is required. In addition, in response to the increasing demand for long-term recreation, it is also necessary to develop a marina as the core of the resort base.

By the way, despite the development and popularization of marine recreation, the marina supply is not sufficient, and many yachts and motorboats that cannot be accommodated are left.

Generally, motor boats and yachts are stored in a one-story storage box, or for example, a building-type three-dimensional boat storage box as shown in FIG. 3 is known. However, in order to store the boats on the sea in the building-type three-dimensional boat shed, it was necessary to consider the change in water level due to the ebb and flow of tide and the flow of tide.

The present inventor separately proposed a three-dimensional marine yard, and provided a freely movable gate-type crane in the three-dimensional garage that doubles as a platform to enable stacking and unloading of the three-dimensional garage, three-dimensional storage of boats and a small beach. We made effective use of the quay.

(Problems to be Solved by the Invention) The present invention proposes a lifting device for a gate-type crane, which solves the problems of lateral shake of a boat due to tidal current and change of water level due to tide in the three-dimensional marina yard.

(Means for Solving the Problems) According to the present invention, a first guide is provided on a main pillar of a traveling gantry crane, a boat seat is laid horizontally between the main pillars so that the boat guide is vertically movable, and a second guide is provided on the boat seat. It is provided and the three-sided suspension stand is projected so that it can move up and down.
The guide has a length that extends to a level lower than the quay level when the boat seat is at the lowest position, and the guide of a gate-type crane in a three-dimensional boathouse equipped with a gripping device for a suspension frame column that stores the boat on a triangular suspension platform. It is a lifting device.

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

FIG. 1 is a side view of the present invention, and FIG. 2 is a front view of FIG.

The lifting device of the present invention is provided with the first guides 12 and 12 (hereinafter referred to as the first rails) on the main columns 11 and 11 of the traveling gate type crane 10.
A boat seat (13) is horizontally installed between the main columns (11, 11), and the boat seat (13) can be raised and lowered by a hydraulic motor (not shown).

Further, the boat seat 13 has second guides 14, 14 extending to a level W lower than the quay level L when the boat seat is at the lowest position.
(Hereinafter referred to as the second rail), and the triangular suspension base 15 is provided so as to project from the quay to the sea side, and the triangular suspension base 15 can move up and down the second rails 14 and 14 by a hydraulic motor (not shown). is there. The three-sided suspension base 15 has a gripping mechanism 17 on the lower surface, and a suspension frame for accommodating the boat 20.
The tips of the 16 columns 18 can be gripped.

The gate type crane 10 travels in the marine yard by means of wheels 21.

Since the first rails 12 and 12 are erected on the entire length of the main pillar of the portal crane, the boat seat 13 is moved up and down to a desired height of the main pillar by the hydraulic motor, and the second rails 14 and 14 are set at the quay level. Since it extends to a level W lower than L, the boat 20 that floats above the sea is suspended.
It can be reliably placed on the 16 pedestals 19.

Further, since the rail and the boat seat are fixed via rollers (not shown), there is no lateral shake due to the influence of the tidal current.

The configuration of the present invention is as described above. Next, an application example of the present invention will be described.

When a boat on the sea runs by itself on the quay, the gate-type crane 10 seat
13 is descended, and further the triangular suspension base 15 is descended using the second rail as a guide. The three-sided suspension stand 15 suspends a suspension frame 16 suitable for the boat size based on the information obtained in advance and suspends the suspension frame 16 in the sea.

When the boat 20 stored in the suspension frame 16 is placed on the cradle 19, the boat seat
13 rises, and the hanging frame 16 is carried to a desired position by traveling of the gate crane. The suspension frame 16 is configured by arranging four legs on a diagonal line, and the ends of the columns of the lower suspension frame 16 of the same size and the ends of the columns of the upper suspension frame 16 are fitted together to form a three-dimensional boathouse.

In order to stack the upper suspension frame 16 on the lower suspension frame 16, the boat seat of the portal crane can be raised to the position indicated by the broken line in the drawing. This raises the boat seat to the upper limit position of the first rail and the second seat of the boat seat.
It means raising the triangular suspension to the upper limit position of the rail.

That is, by disposing the first rail and the second rail, the elevating stroke of the boat is increased, and the gate type crane can be downsized.

(Effect of the Invention) In the lifting device of the present invention, since the boat guide is vertically movable by providing the first guide on the main pillar of the portal crane, the boat seat can be stopped at a desired height of the portal crane. Further, a second guide extending to a level lower than the quay level is provided in the boat seat in a state in which the boat seat is at the lowest position to allow the triangular suspension stand to move up and down, and the rail and the boat seat are fixed via rollers. Therefore, when storing the boat in the suspension frame, it is possible to prevent changes in the water level due to the ebb and flow of the tide and lateral shake of the suspension frame due to the flow of the tide, and it is possible to reliably store the boat on the sea in the suspension frame. Is large.
