Description

Description: TECHNICAL FIELD The present invention relates to a crane device for a small boat used for leisure or the like.

(Prior Art) Conventionally, small boats used for leisure or the like are parked on public facilities or facilities with a membership system provided on the coast near the shoreline. For example, yacht harbors parked on the sea, Yacht harbors with boat parking facilities on land are common.

(Problems to be Solved by the Invention) However, recently, as leisure and marine sports have become popular, small vessels (motor boats, yachts, etc.)
The number of small boats has also increased due to the increase of leisure entrances, and the number of small boats has not been able to keep up with the boats. There are many boats that are running.

On the other hand, in yacht harbors, which have boat parking facilities on the coastal sea near the coastline, it is not possible to increase the number of large-scale boat parking facilities because the optimum location for harbors built near the coast is limited.

In addition, at yacht harbors with onshore parking facilities, it takes enormous costs to acquire land in contact with the coast or rivers, so the number of boats accommodated is small, storage costs for boats are increased, and use by non-specified persons is restricted. Problems arise.

Furthermore, if a boat is illegally occupied on the inland waters of canals or small and medium-sized rivers, it may impede flow due to floods caused by typhoons or heavy rain, damage to other facilities due to the spill of boats, It can damage the structures and embankments of small and medium-sized rivers, which can be a major disaster.

Therefore, it is conceivable to provide a boat parking facility using a vast riverbed. In that case, however, there is a problem how to provide a crane device for a small boat.

In other words, the depth of a river is different from that of a port, so it is difficult to determine the location of the boat, and even if the location of the boat is determined, the water level changes due to the ebb and flow of the boat, and the boat lands. There is a risk that simply installing a crane on a riverbed or revetment will damage the form of the river, causing a problem that the same function as in the past will not be exerted against floods and the like.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a crane device for a small boat that can maintain the current form of a river and can ascend and descend reliably without damaging a boat in a river. To provide.

(Means for Solving the Problems) In order to achieve the above object, a small boat crane device according to the present invention includes a suspension pier installed on a facing seawall upstream of a port or a river flowing into the open sea; It is provided with a lift port provided in a portion located above the river and capable of lifting and lowering the boat, and a traveling crane that travels between the lift port and the suspension pier portion above the riverbed to lift the boat. Features.

(Function) When in use, the boat is moved by a traveling crane and suspended above the river for navigation, and when returning from navigation and parked, the boat is lifted by a traveling crane and moved to park on the riverbed side. I do.

Since the traveling crane runs on the suspension pier, the form of the river is maintained as it is, and there is no bridge girder or any other structure in the main stream of the river, so there is no risk of hindering the navigation of other boats.

Further, since the traveling crane moves on the suspension pier, even if the water depth of the river changes due to the ebb and flow of the tide, the boat can be reliably moved up and down without damaging it at a deep water position.

Also, the frame of the traveling crane is composed of an upper frame and a lower frame, and the lower frame is arranged so as to be movable along a main gadder provided in parallel with the suspension pier via a support, and A drive device for moving along the main gadder is disposed, and the upper frame is disposed on the lower frame so as to be movable in a direction orthogonal to the longitudinal direction of the main gadder, and in the upper frame in the direction. When a drive unit for moving is arranged, and a hoist is mounted on the upper frame, the boat can move in two orthogonal directions, so when lifting the boat, adjust the center of gravity of the boat and use the lift It can be adjusted so that it does not hit.

In addition, if a hoisting device is provided on the main gadder and a gondola that moves up and down by this hoisting device is used, it can be used for lifting and lowering of boat operators and boats, and it is possible to support the navigation of other ships by raising it normally. Absent.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
