Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ship for transporting a large number of vehicles (especially a ship for exporting new vehicles abroad). The present invention relates to a floor structure of a vehicle transport ship capable of fixing tires of a vehicle to a floor surface.

[0002]

2. Description of the Related Art When a new car is loaded on a ship and exported overseas, a large number of ring-shaped fittings 20 provided under bumpers in front of and behind the car and a large number of pieces are mounted on the floor 5 of the ship, as shown in FIG. The car was fastened to the floor from the front and back by fixing the hole 21 that was vacated to the floor with a fastening belt 22 with a hook at the tip, preventing the car from slipping due to the sway of the ship. . Four fastening belts 22 per car
The task of linking each one was quite time-consuming.

[0003] Moreover, when a vehicle exported from Japan by ship in this way is to be unloaded from the ship locally, it is a serious task for the local work vehicle to remove the fastening belts attached to a large number of vehicles one by one. At times, it is not unusual to handle the tightening belt violently or move the car without removing it properly, and the hook of the belt may damage the new car.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and allows a vehicle to be fixed firmly to the floor of a ship without any special work, and the cost is low. The aim is to provide a floor structure for vehicle transport ships.

[0005]

In order to achieve the above-mentioned object, a floor structure of a vehicle transport ship according to the present invention is provided with a non-slip plate having a slip-preventing means on its surface side to be engaged with a ground contact portion of a tire. It is characterized in that it is fixed to the floor just below the tires before and after the parked car. Here, the slip preventing means means all means for mechanically holding the tire so that the tire does not move by fitting into the tread groove of the tire or supporting the ground contact portion of the tire from the surroundings.
Specifically, it suffices if a large number of protrusions having an appropriate height (at least 1 mm or more) are provided, and the form of the protrusion is not limited. For example, the protrusion may be formed by punching, pressing, or the like on an iron plate, or may be integrally formed by providing an infinite number of depressions in a mold during molding. Further, even with so-called expanded metal in which a steel plate is slit and stretched to form a mesh, the mesh of the mesh which is three-dimensionally twisted can be a means for preventing misalignment. Also, the means for fixing the anti-slip plate provided with such slip prevention means to the floor surface may be integrally attached to the floor surface by welding, bonding, or the like, but is detachably attached using bolts or screws. May be. The anti-slip plate may be partially laid at the tire contact point, or may be entirely laid on the floor, depending on the anticipated parking situation of the car.

If the floor of the ship is configured in this manner, the vehicle can be parked only with the front and rear tires on the anti-slip plate, and the slip prevention means can fit into the tread grooves in the vertical and horizontal directions of the tire. Since the tires are fixed, it is possible to reliably prevent the vehicle from sliding in all directions of front, rear, left, right, and diagonal directions.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the floor structure of a vehicle transport ship according to the present invention will be described below with reference to the drawings. First, FIG. 1 shows a non-slip plate 1 used in the floor structure of the present invention, which is formed by punching a substrate 2 and projecting on a surface thereof into a tread groove 4 of a tire. 3
Are protruding innumerably. The height of the projection 3 is at least 1 mm, preferably about 5 mm. The projection 3 is shown in FIG.
As shown in FIG. 3A, the substrate 2 may be formed by press working, or as shown in FIG. 3B, may be integrally formed at the same time as the substrate 2 is molded with a mold. Further, as the non-slip plate 1, a commercially available expanded metal cut into an appropriate size may be used as it is.

The anti-slip plate 1 does not need to be laid entirely on the floor 5 of the ship, but only needs to be installed under the tires. In the cabin, the cars are parked in an orderly and longitudinally and horizontally spaced manner with a space of about 30 cm in the front and back and about 10 cm in the left and right between the cars, so that the anti-slip plate 1 is made to go straight in the direction of the car as shown in FIG. And the front and rear tires 6 across multiple cars
It is desirable to lay it long underneath. Therefore, the non-slip plate 1 is formed in an elongated band shape having a width of about 30 to 50 cm and a length of about 1 to 2 m, and is continuously laid on the floor 5 while being welded and fixed in some places. Of course, a hole may be formed in the floor surface 5 and the anti-slip plate 1 may be fixed with screws or bolts.

In this way, the anti-slip plate 1 is laid on the floor 5 of the cabin in parallel and long at a predetermined interval in the width direction of the ship, and the tires 6 and 6 at the front and rear of the vehicle are respectively provided. When the vehicle is on the non-slip plates 1, 1, the vehicle is parked. Then, the protrusion 3 on the surface of the anti-slip plate 1 is caught in the tread groove 4 of the tire contact surface, so that the tire 6 can be reliably prevented from slipping in all directions, ie, back and forth, left and right, and diagonally, and furthermore, the vehicle from sliding. According to this method, no special work is required to fix the vehicle, so that labor costs can be significantly reduced as compared with the conventional fixing method using a fastening belt.

[0010]

According to the floor structure of the vehicle transport ship of the present invention, the means for preventing slippage of the surface of the anti-slip plate is fitted into the tread groove of the tire simply by parking the car on the anti-slip plate. Since the tires are fixed, it is possible to reliably prevent the vehicle from slipping without any special work. Further, since the anti-slip plate used is of a very simple structure, it can be implemented at a low cost on any ship.
