Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to at least two rack bodies for transporting products such as H-section steel, steel sheet piles, flat bars, steel pipes, steel rods and coils formed by winding strip-shaped thin steel sheets by sea. The present invention relates to a marine transportation rack body retaining jig that stably holds the postures of a plurality of aggregates formed by stacking a combination of products mounted on a rack configured in (1).

[0002]

2. Description of the Related Art Conventionally, when a steel product such as an H-section steel is transported by sea by a ship, the product is handled by a crane or the like in units of 2-3 units and bulk-loaded in a hold.

[0003]

However, in this conventional method, since the number of products that can be handled by one handling is small, the work efficiency is low, and it is necessary to moor the ship to the quay for a long time. . In addition, in order to secure the loaded products in the hold, it is necessary for an operator to enter the hold and perform the securing operation, which is always dangerous.

The present invention was devised in view of these problems, and in order to efficiently and safely load steel products such as H-section steel on a ship or land on a ship and transport it over the sea, a rack body on which the products are mounted is stacked. The object of the present invention is to stably hold the posture of the aggregate formed in this manner in the hold.

[0005]

[Means for Solving the Problems]
Side beam members 4 are erected on both side ends of the bottom beam member 3, suspension plates 6 are erected on both side beam members 4, and the suspension plates 6 of the lower rack body 2 are inserted from below to engage during stacking. A rack 1 composed of at least two rack bodies 2 forming a combined space 5 is provided with a large number of combinations of products S mounted in a cargo hold 8 to stabilize the postures of a plurality of parallel-positioned aggregates 7. In order to keep it, the jig body 11, the fixing mechanism 12 and the press contact mechanism 14 for connecting and retaining the uppermost rack bodies 2 of the assembly 7 are used.

The jig body 11 is a flat plate body having a length substantially equal to the width of the hold 8, and a combination of the suspension plate 6 and the side beam member 4 of the rack body 2 at the uppermost stage of the assembly 7 is inserted therethrough. It has a plurality of openings 13. The fixing mechanism 12 is the jig body 1
The side walls 9 of the hold 8 are pressed to fix the jig body 11 to the hold 8 by being fixed to both side ends of the hold 1. The pressure contact mechanism 14 is provided in the jig body 1
In order to connect the combination of the side beam member 4 of the rack body 2 and the suspension plate 6 that has been arranged in the vicinity of the opening 13 to the jig body 11, the side beam member 4 and the suspension plate 6 are connected. The combination with 6 is pressed.

As the press contact mechanism 14, a journal jack or a pressing body such as a cylinder body in which the tip of a rod body that moves forward and backward is directly pressed against the combination of the side beam member 4 and the suspension plate 6 that has entered the opening 13. 15 or the air dunnage 16 is preferable, and when the pressure contact mechanism 14 is composed of the pressing body 15, it is desirable that the pressing body 15 is attached so as to be movable along the longitudinal direction of the jig body 11.

[0008]

First, the operation of the retaining jig 10 according to the present invention in which the pressing mechanism 14 is composed of the pressing body 15 will be described with reference to FIGS. 1 and 2. In order to connect the rack body 2 on the uppermost stage of each aggregate 7 to the jig body 11 in order to keep the posture of the aggregate 7 stable by the retaining jig 10, first, the retaining jig 10 is
The combination of the side beam member 4 and the suspension plate 6 of the rack body 2 is inserted into the opening 13 of the jig body 11 and assembled in a straddle shape on each aggregate 7. Next, while maintaining this state, the fixing mechanism 1 provided at both end portions of the jig body 11
At 2, the tension is applied to the side wall 9 of the hold 8. The retaining jig 10 is fixed in a erected state between the side wall surfaces 9 by bulging the side wall surfaces 9 of the two fixing mechanisms 12 facing each other.

After fixing the retaining jig 10, the pressure contact mechanism 14
A pressing force along the longitudinal direction of the jig body 11 is applied to the combination of the side beam member 4 and the suspension plate 6 inserted into the opening 13. The uppermost rack body 2 of each aggregate 7 is connected to the retaining jig 10 by the action of the pressing force on the combination of the side beam member 4 and the suspension plate 6, and the inside of the hold 8 is held through the retaining jig 10. The position of will be fixed.

Since the uppermost rack body 2 of each aggregate 7 is retained by the retaining jig 10, the posture of each aggregate 7 in the hold 8, that is, the stacking posture of each rack 2 is stable. Will be maintained. As a result, the aggregate 7 can maintain a stable posture even when the ship sways during sea transportation, and it is possible to prevent cargo movements.

In order to remove the retaining jig 10, contrary to the case of attachment, first, the action of the pressing force by the pressure contact mechanism 14 is eliminated and the connection with each aggregate 7 is released. Next, the tension on the both side wall surfaces 9 by the fixing mechanism 12 is released, and the retaining jig 10 that has been disconnected from the aggregates 7 and the side wall surfaces 9 is removed by lifting or the like.

When the press contact mechanism 14 is composed of a pressing member 15 such as a journal jack or a cylinder body, the combination of the side beam member 4 and the suspension plate 6 is directly pressed by the tip of the rod member of the pressing member 15. Therefore, the retention of each aggregate 7 by the holding jig 10 is fixed to the initial position where the retention is achieved. Therefore, when the initial position when the retention is achieved is correct, an extremely stable and good retention is achieved. Is achieved. However, since the rod body of the pressing body 15 generally has a limited stroke, the pressing body 15 can be moved along the longitudinal direction of the jig body 11 so that an appropriate retaining position can be initially obtained. It is possible to move by using this movement so that an appropriate holding position can be obtained by this movement.

When the pressure contact mechanism 14 is composed of the air dunnage 16 (see FIG. 3), the air dunnage 16 in the deflated state has entered the opening 13 and is the uppermost rack body of each assembly 7. 2 is inserted and arranged between the combination of the side beam member 4 and the suspension plate 6 and the side wall surface 9 or between the combination of the side beam member 4 and the suspension plate 6 of the rack body 2 of the adjacent assembly 7. After that, air is supplied to the air dunnage 16 to inflate it, and a pressing force is applied to the combination of the side beam member 4 and the suspension plate 6 that has entered the opening 13. The uppermost rack body 2 of each aggregate 7 is pushed by the air dunnage 16 and the side beam member 4 and the suspension plate 6 are applied.
Is it possible to directly press the combination of
Alternatively, the pressing force toward the jig main body 11 side is constantly received, and each assembly 7 is positioned at the upper end position of the jig main body 11.
On the other hand, according to the strength of the pressing force exerted by the air dunnage 16, the air dunnage 16 is held within a certain range, and the stacking posture in the hold 8 is kept in a stable posture.

When the pressure contact mechanism 14 is constituted by the air dunnage 16, the retention of the upper end of the assembly 7 with respect to the jig body 11 does not become immovable, and a certain degree of displacement is possible. There is an advantage that the air dunnage 16 acts as a cushioning material so that the small sway of the ship is not transmitted to the aggregate 7, and that the position adjustment of the press contact mechanism 14 is not necessary.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 4 and 5 show an example of the structure of the rack body 2 retained by the retaining jig 10 according to the present invention. The bottom beam member 3 has a flat plate shape and is open downward and outward. A side beam member 4 having an engagement space 5 is integrally erected, and a suspension plate 6 for suspending the rack body 2 is erected on the side beam member 4.

As shown in FIG. 6, the rack body 2 is formed by combining at least two rack bodies 2 to form a rack 1, and a plurality of products S are mounted between both rack bodies 2 in a crossover manner. Make up the body.

The embodiment shown in FIGS. 1, 2 and 3 is
In order to retain the three aggregates 7 assembled in the hold 8,
Openings 13 are formed at four positions, that is, both side ends of the jig main body 11 and approximately three equal parts along the longitudinal direction. The fixing mechanism 12 is composed of a total of four journal jacks arranged one at each of the front and rear end portions of both end portions of the jig body 11.

The embodiment shown in FIGS. 1 and 2 shows a case where the pressure contact mechanism 14 is composed of pressing bodies 15 each having a rod body that moves forward and backward. The opening bodies 13 are provided one by one with the rod bodies facing outward, and the central opening portion 13 is provided with one pair of the rod bodies facing each other. Assembling of the jig to the jig body 11 is performed by the mounting plate 17
Trying to achieve through. This mounting plate 17
Is a plurality of screw holes 1 in the jig body 11 by bolts 18.
9 is freely attachable to the jig body 11, and the fixing position of the pressing body 15 to the jig body 11 can be adjusted and set.

That is, the height of the assembly 7 assembled in the hold 8 is not necessarily the same for each assembly 7 because the size and type of the product S mounted on the rack 1 are not constant. There is some variation, and the aggregates 7 are not formed by stacking the racks 1 by accurately aligning the racks 1 with each other, and a slight allowable deviation occurs between the stacked racks 1. For this reason, it may be the side beam member 4 or the suspension plate 6 that enters the opening 13 and faces the pressing body 15, and the stack deviation of the racks 1 forming the aggregate 7 may occur. From this, since the intrusion position of the rack body 2 portion with respect to the opening portion 13 cannot be accurately specified, a large position adjustment of the pressing body 15 with respect to the rack body 2 portion invading the opening portion 13 is performed by the jig of the mounting plate 17. This is achieved by adjusting the mounting position with respect to the main body 11, and fine position adjustment is achieved by adjusting the forward / backward stroke of the rod body of the pressing body 15.

FIG. 3 shows an embodiment in which the pressure contact mechanism 14 is composed of an air dunnage 16, and one air dunnage 16 is provided in each opening 13 and is provided in the openings 13 at both ends. The air dunnage 16 thus formed is provided between the side wall surface 9 and the rack body 2 portion that has entered the opening 13.
And the air dunnage 1 provided in the central opening 13
6 are respectively inserted between the rack body 2 parts that have entered the opening 13.

When the press-contacting mechanism 14 is constituted by the air dunnage 16, the assembly 7 is retained between the rack body 2 part that has entered the opening 13 and the side wall surface 9 and the rack body 2 that has entered the opening 13. Air dunnage 1 inserted between the parts
This is accomplished by inflating 6 with constant pressure. In this case, the width of the gap into which the air dunnage 16 is inserted is not necessarily constant, so the amount of compressed air that is press-fitted into the air dunnage 16 is set according to the value of this gap.

FIG. 7 shows an example of use of the retaining jig 10 of the present invention. This is a three assembly 7 formed by stacking a combination body in which a H-shaped steel product S is mounted on a rack 1 (see FIG. 6) configured by a pair of rack bodies 2 in a hold 8.
Is held in a stable posture by the retaining jig 10. The uppermost rack body 2 of each aggregate 7 is firmly retained by the retaining jig 10, so that the lower rack bodies 2 assembled to the rack body 2 and the aggregate body 7 formed by these rack bodies 2 The posture of is maintained stable.
Therefore, the product S is not affected by the shaking of the ship during the sea transportation.
It is possible to minimize the load movement of.

[0023]

As described above, the retaining jig of the present invention mounts the product of each assembly by fixing the uppermost rack body of each assembly stacked in the hold against the side wall surface of the hold. It is possible to maintain the stable rack in a stable posture and reliably prevent product load movements. This makes it possible to achieve extremely safe marine transportation with the product mounted on the rack.

Since a desired number of openings are formed in the jig body of the flat plate body and the fixing mechanism and the pressure contact mechanism are assembled to the jig body, the whole structure is simple and
The restraint operation is easy and the desired restraint function can be reliably obtained.
