Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a sill used for storing a yacht or the like on land.

[Conventional technology]

When storing a yacht or the like on land, it is common to use a movable platform.

By the way, when the hull of a yacht or the like is supported by the sill, most of the weight of the hull is received by the ballast or the center keel, but the side wall must also be supported in order to stabilize the hull.

However, the shape of the side wall varies greatly depending on the location, and it is made of a very thin and soft material to reduce the weight of the hull, and damage may occur when a large force is applied to the side wall.

As a conventional ship base, there have been proposed one in which a belt-shaped receiving portion is provided on a movable base, and one in which a receiving portion made by measuring the shape of a hull is provided on the movable base.

[Problems to be solved by the device]

In any of the structures described above, the conventional deck described above is very difficult to position the hull because the boarding work is performed by immersing the deck in the water.
Large forces may be applied to the sidewalls, which may cause damage to the hull.

Also, in the case of a large ship, there are large protrusions such as ballast at the bottom of the hull, so the sill equipped with the belt-like receiving part must be deeply submerged in water, which makes it difficult to board the ship and is not practical. .

Further, the latter special deck is inconvenient in that it cannot be stored in other shapes because it is tedious and time-consuming to manufacture, costly and uneconomical, and lacks versatility.

Therefore, in view of the above points, an object of the present invention is to provide a platform that can respond to a change in the shape of the hull with a little adjustment, has high versatility, and can accurately adjust the embarkation position of the hull. Especially.

[Means for Solving the Problems]

In order to solve the above problems, the present invention establishes pillars at four positions on a movable table supported by wheels, and vertically positions a swingable hull receiving portion at the upper end of each pillar. A hull that is mounted so that it can be adjusted, and that has a hull positioning stopper on the movable base that allows for position adjustment in the front-rear direction and a hull bottom support that allows position adjustment in the front-rear and up-down directions. The receiving part is formed in a T shape in which a pad mounting part is provided at a right angle on the tip of the mounting arm, and the rear end of the mounting arm is mounted on a pillar with a pin, and the holder is swingable up and down with the pin as a fulcrum. The pad mounting portion of the holder is formed with a pair of support pads, which are independently pivotably pivoted by pins, at both upper and lower ends thereof.

[Action]

When the hull such as a yacht enters the movable platform submerged in the water and the ballast protruding from the lower surface of the hull is brought into contact with the stopper to raise the movable platform toward the land together with the hull, the hull bottom receiving The bottom of the hull is supported to support most of the weight, and the hull receivers attached to the upper ends of the columns support the hull at four positions.

The hull receiving portion is swingably attached to the pillar, and the pair of support pads independently pivotally swing so that the support pad supports the hull along the outer surface shape of the hull. , The hull is kept horizontal when pulled up to the ground.

The holder 6 is formed in a T-shape in which a pad mounting portion is provided at the tip of the mounting arm at a right angle, the rear end of the mounting arm is mounted on the pillar 3 by the pin 5, and a pair of upper and lower end portions of the pad mounting portion are provided. The support pads 8 and 8 are independently pivoted by pins 7 and 7 so as to be swingable.

The hull receiving portion 4 is arranged so that the support pads 8 face inwardly on the pillars 3 on both sides.
When the hull A is supported, it follows the curved surface of the hull A by the double swinging with the fulcrum as a fulcrum.

On both sides of the movable table 1, a horizontal rail 10 is installed between the front and rear pillars 3, and a stopper rod 11 mounted between the horizontal rails 10 on both sides.
A V-shaped plane hull positioning stopper 12 is provided at the center of the.

The stopper rod 11 is fixed to the horizontal rail 10 by fixing brackets 13 provided at both ends thereof, and the stopper rod 11 and the stopper 12 are moved along the horizontal rail 10 in the front-rear direction of the movable table 1 by operating the fixing bracket 13. The position can be adjusted freely.

As shown in FIG. 2, the stopper 12 receives the ballast B of the hull A that has entered the movable table 1 from the rear, and serves to make the positional relationship between the hull A and each hull receiving part 4 constant.

A hull bottom support 14 for supporting the weight of the hull A in which a ballast B is in contact with a stopper 12 is mounted on the movable table 1 so that the position of the hull bottom 14 can be adjusted vertically and in the front-back direction of the movable table 1.

This hull bottom support 14 has a support plate at the center as shown in FIG.
It is composed of a support frame 16 to which 15 is attached, and a mounting bracket 17 for fixing the end portion of the supporting frame 16 to the movable table 1. The mounting bracket 17 is
A vertical column 19 is provided on the rear surface of the inverted L-shaped mounting portion 18 placed on the movable table 1.
And the mounting portion 18 is fixed to the movable base 1 with the horizontal holes 20 and the bolts 21 provided at a constant interval in the movable base 1.
