Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boat transporting device for transporting a boat between a landing place on the land and a waterside, and for hoisting the boat to and from the water surface and a berth. ..

[0002]

2. Description of the Related Art In recent years, it has been desired to expand the equipment for parking boats in response to the increasing trend of boat leisure, but a multi-dimensional automatic warehouse for storing boats three-dimensionally on land equipment is also found in general marinas. It started to come.

When constructing a boat yard on land,
A transport device is required for transporting the boat between the harbor and the waterside, landing the boat on the water surface, and hoisting the boat from the water surface and storing the boat at the harbor. Conventionally, as such a transporting device, as shown in FIGS. 6 and 7, a boat transporting device in which a hoist device H for hoisting and unloading boats is provided on an upper portion of a gate type frame F having a self-propelled function. Has already been put to practical use.

[0004]

However, in the case of this conventional apparatus, the boat B is carried by a gate type carriage with a hoist, so to speak, and the boat B is lifted up and down between the pillars of the gate type frame F. Therefore, when the boats are parked in parallel, the space D between the boats is set so that the wheels W provided on the gate pedestals can be accommodated between the boat stands S adjacent to each other. It has a drawback that it has to be widely used and that a pier Q for loading the wheels W of the legs must be provided on the quay.

The present invention has been devised in order to eliminate such disadvantages of the prior art, and its main purpose is to reduce the pitch between boats at a harbor and to mount a trolley. An object of the present invention is to provide a boat transporting device configured so that it is not necessary to provide a pier for the pier on the pier.

[0006]

According to the present invention, such an object is to carry a boat between a waterside and a berth on land, and to lift and lower the boat to and from the water surface and a berth. The structure of the boat transport device for carrying out is as follows: a self-propelled traveling carriage, a telescopic boat support frame provided on the upper portion of the carriage so as to be extendable / contractible in a horizontal plane, and a boat lifting / lowering provided on the support frame. And a device.

[0007]

According to such a structure, it is possible to carry out the hoisting / unloading work at a position overhanging from the traveling area of the traveling carriage.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

1 to 4 show the entire boat transporting apparatus constructed according to the present invention. The boat carrying device 1 includes a traveling carriage 2, a boat support frame 3 provided on the upper portion of the carriage 2, and an elevating device 4 provided on the support frame 3.

The traveling carriage 2 has four pillars 5, an upper fixed frame 6 composed of a beam extending from the upper end of the pillar 5 in the front-rear and left-right directions, and a girder 7.8 in which the lower part of the pillar 5 is connected in the front-rear and left-right directions. And drive wheels 9 are provided at the lower ends of the columns 5. The drive wheel 9 is driven by a motor 10 with a speed reducer in forward and reverse directions and is steered by another electric motor 11 so that forward and backward movements and turning movements can be performed freely. Is becoming

The fixed frame 6 at the upper end of the pillar 5 is assembled so as to have a U-shape when opened from one side when viewed from the upper side, and supports the boat support frame 3. Inside the fixed frame 6, a first movable frame 12 having a U-shape similar to the fixed frame 6 is slidably fitted in the fixed frame 6 so as to be retractable from the open end of the fixed frame 6. A second movable frame 13 is slidably fitted inside the first movable frame 12 so as to be retractable from the open end of the first movable frame 12. These frames can be telescopically expanded and contracted by being slidably driven by a known push-pull drive mechanism using, for example, a hydraulic cylinder or a chain / sprocket.

The lifting device 4 is attached to the second movable frame 13, and has four rack gears 14 extending vertically and a pinion gear 15 meshing with the rack gears 14.
And a reduction gear motor 16 for driving the pinion gear 15 to rotate, and a pickup arm 17 rotatably fitted to the lower end portion of each rack gear 14, so as to be rotatable on the second movable frames 13 on both sides. By driving both pinion gears 15 supported by bearings to rotate synchronously, each rack gear 14 synchronously moves up and down, and a pickup arm 17 provided at a lower end of each rack gear 14 moves up and down. Further, as shown in FIG. 5, the pickup arm 17 pushes and pulls a hydraulic cylinder 19 fixed to a connecting member 18 that connects the front and rear rack gears 14 to each other, thereby pushing the pulling arm 17 to a load receiving position facing right side (on the left side in FIG. 5). (State) and the unloading position along the connecting member (state on the right side in FIG. 5) can perform a turning motion.

Next, the operating procedure of this apparatus will be described.
First, the present apparatus is stopped at a position vertically aligned with the target boat B, and the boat support frame 3 is extended on the boat B. Next, the rack gear 14 is lowered and the pickup arm 17 is swung inward to stack the racks L in two stages.
The boat B placed on the top is scooped up together with the pallet P. Then, the boat B is floated above the rack L, and then the boat support frame 3 is contracted so that the boat B is housed inside the fixed frame 6 (a state shown by an imaginary line in FIG. 4). In this state, the trolley 2 is run and heads for the disembarkation area.

At the disembarking place, the boat B can be landed together with the pallet P by extending the boat support frame 3 and then lowering the rack gear 14.

In the case of a boat landing on the water, the reverse operation is performed.

The lifting / lowering device 4 is not limited to the rack / pinion type shown in the above embodiment, but may be a linear sliding type cylinder device or a wire winding device. Is also good.

[0017]

As described above, according to the present invention, the boat can be lifted and lowered at a position overhanging the traveling carriage, so that the boat can be lifted and lowered at a position outside the traveling area of the traveling carriage. Therefore, it is not necessary to provide a space between the boats when the boats are parked in parallel, so that space efficiency can be improved.
Moreover, since there is no need to install a pier for loading a truck on the quay, the overall equipment cost can be reduced.
