[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hull moving vehicle used for transporting a hull such as a motorboat or a yacht from land to sea, or from sea to land, and particularly to a bogie on which the hull is mounted. It relates to a towing platform for towing.

[0002]

2. Description of the Related Art Small motor boats and the like used for leisure or competition are usually rarely anchored at sea, and after use, they are pulled up on land and placed on a dedicated cart. It is common to move to a designated storage location and transport it to the shore only when in use.

Conventionally, when transporting these boats and the like, a method of moving a trolley on which the hull is mounted using an existing forklift or the like has been performed. A fork is inserted under the bogie from below to lift and move the hull, so the width of the moving passage needs to be longer than the entire length of the hull, so the space for securing the moving passage increases and the hull can be stored in a storage location The number of the hulls is restricted, and the hull has an unstable posture when moving, which may cause a collision with another hull being stored.

A hull moving vehicle for solving this problem is:
This is proposed in Japanese Utility Model Laid-Open No. 60-7271, which will be described with reference to FIG. FIG. 5A is a side view of the hull moving vehicle, and FIG. 5B is a plan view of the hull moving vehicle. In the figure,
a is a hull moving vehicle, b is a bogie, 51 is a handlebar, 52
Is a forward / backward switch, 53 is a front wheel, 54 is a hydraulic motor and battery storage section, 55 is a frame, 56 is a loading platform (elevating body), 57 is a turntable (towing platform), 5
7a is a rising wall, and 59 is a rear wheel.

In order to move the truck b on which the boat is mounted, the hull moving vehicle a is moved to enter the front end of the truck b up to the rising wall 57a of the towing platform 57, and then is moved by a hydraulic cylinder (not shown). When the elevating body 56 is raised, the caster of the carriage b floats from the ground, and the carriage b is placed on the tow base 57 of the elevating body 56 and becomes movable. Hull moving vehicle a
When the vehicle turns, as shown in FIG. 5 (B), the towing platform 57 rotates to gradually change the traveling direction of the carriage b.

[0006]

The conventional hull-moving vehicle shown in FIG. 5 can move by pulling the hull in the front-rear direction, so that the width of the moving passage can be slightly larger than the width of the hull. The space for securing the passage can be reduced.

However, since the elevating body 56 and the towing stand 57 are provided above the rear wheel and the frame 55, the height of the frame of the carriage b must be higher than that of the towing stand 57, and all the existing carriages need to be replaced. It has the problem of having to be repaired.

Further, the bogie b is supported on the towing platform 57 only by the frictional force, so that the bogie b
Is unable to follow smoothly, and if the rear wheel of the truck b is caught by an obstacle during the movement of the hull moving vehicle a, the truck b may come off the towing platform 57 and the truck b may fall off. have.

Further, the height of the frame 55 must be reduced.
And the diameter of the rear wheel 59 cannot be increased.
In addition, since the front wheel 53 is driven, the load of the bogie is applied while the rear wheel 59 is in a free state, and the rear wheel 59 slips on a wet road surface or on a slope, making it impossible to tow. have.

The present invention solves the above-mentioned conventional problems. In addition to reducing the space for securing a moving route and increasing the number of hulls that can be stored in a storage place, the present invention also provides a high-priced hull. It is an object of the present invention to provide a towed vehicle for a hull mobile vehicle that can be applied to the movement of all bogies of different sizes and that can improve the turning property and stability during the movement of the bogie.

[0012]

In the present invention, for example, as shown in FIG.
When the hull moving vehicle 1 is advanced obliquely from the front end E of the bogie D as shown by the arrow in the figure, the front end E abuts on the vertical surface of the appropriate locking step B of the towing stand 25 (FIG. A). When the hull moving vehicle 1 is further advanced, the towing stand 25 rotates in the horizontal direction, and the front end E comes into contact with the vertical surface of the locking step B (FIGS. B and C). In this state, when the lifting body 24 is raised by the hydraulic cylinder device 14, the front end E is placed on a horizontal surface, and the truck D is raised at the front end by the towing platform 25,
Next, when the hull moving vehicle 1 is gradually turned as shown by the arrow in the figure (FIG. D), the towing platform 25 also gradually rotates, and the traveling directions of the hull moving vehicle 1 and the bogie D eventually coincide (FIG. E). ), It can be transported to a predetermined place while being pulled by the locking piece 41 . Conversely, when the bogie D is moved to a predetermined location and separated from the hull moving vehicle 1, the procedure is reversed.

A locking piece 41 is protruded.

It should be noted that the pin 3 which pivotally connects the tow
9 and 40 are preferably as close as possible to the axle 9, so that the turning radius of the towed truck becomes small and small turning is possible, and when the hull is lifted, the front of the vehicle body is lifted. Can be prevented. The locking step C in the base plate 25b is used when lifting and towing a low bogie. In this case, the bogie can be locked by inserting a pin or the like into a through hole formed in the rear end. .

Next, the operation of the above embodiment and the procedure for transporting a hull such as a motor boat will be described.

FIG. 1 shows a procedure for lifting the motor boat M from the sea. First, the front end E of the empty bogie D is locked to the locking piece 41 of the upper or middle appropriate locking step A or B of the towing platform 25.
Is retracted until the bogie D is located almost directly below the motor boat M (the state of FIG. 1). In this state, when the hydraulic pump is driven to supply the hydraulic oil to each hydraulic cylinder device 14 at the same time, both piston rods 14a are extended, and the first left and right links 21 connected thereto are connected to the horizontal shaft 29. It is rotated counterclockwise in side view as the center. When the first link 21 rotates, the elevating body 2 pivotally attached to this rear end portion
4 and the towing platform 25 pivotally attached to the elevating body 24,
By the parallel link action of the link 21 and the second link 22, the link 21 and the second link 22 are integrally lifted while maintaining the vertical state.

As a result, the front portion of the bogie D is raised by the towing stand 25, and the front portion of the motor boat M is lifted by the support base S fixed in front and having an inverted octagon in front view. Next, when the hull moving vehicle 1 is gradually advanced, the boat M also moves forward while being supported by the trolley D, and when the hull moving vehicle 1 has advanced to some extent, that is, in a gap where the rear part of the trolley D appears from the sea surface, The lower surface of the rear portion of the motor boat M starts to be supported by the support base S fixed to the rear portion. Then, when the hull moving vehicle 1 further moves forward, the entire motor boat M is pulled up from the sea and completely placed on the carriage D, and can be transported to a predetermined place while being towed as it is.

On the other hand, when the hull is transported to the shore and floated on the sea, the trolley D may be submerged with the hull mounted on the trolley D in a manner opposite to the above, and no manual operation is required. Can be done without.

[0028]

As apparent from the above description, according to the present invention, the hull moving vehicle approaches the bogie obliquely, the bogie is locked to the towing platform, and the hull can be moved in the front-rear direction. The width of the hull may be slightly larger than the width of the hull, so that the space for securing the moving route can be reduced, and the number of hulls that can be stored in the storage location can be increased.

In addition to this, by raising and lowering the tow stand by the elevating body, it can be applied to the movement of all the bogies having different frame heights. , So that the bogie can smoothly follow when turning, and even if the rear wheel of the bogie is caught by an obstacle, the bogie will not come off the tow base,
The turning property and the stability during the movement of the carriage can be improved. Also, mount the towing stand behind the rear end of the chassis 2.
Therefore, the diameter of the rear wheel can be made large, and combined with the method of driving the rear wheel
It can also act a load of the truck to the rear wheel to prevent slipping of the rear wheels on wet road surfaces and slopes with water.

Further, it is easy to connect to and disconnect from the bogie, and by connecting and towing the bogie, the work of transporting the hull from land to sea or from sea to land can be extremely easily performed. The work of floating the mounted hull on the sea or pulling it up from the sea and mounting it on a trolley or the like can be performed easily and safely while the trolley is being pulled, which is excellent in labor saving and workability.
