Description

Container connector {CONTAINER CONNECTION DEVICE}

The present invention relates to a container connector that connects the upper and lower containers to each other when stacking containers, and more particularly, to an automatic container connector that can be automatically disconnected by pulling up a container during discharging.

When transporting a large number of containers by ship, the containers stacked in multiple stages up and down are connected by container connectors so that the cargo does not collapse against the shaking (rolling, pitching) of the hull.

The container connector is a plate-like connection sheet disposed between the corner members of the stacked containers, upper and lower pedestals which protrude from the connection sheet and are positioned by fitting the container connector to the groove holes of the upper and lower corner members, respectively, and the pedestal. The upper and lower cones provided at the front end of the upper and lower cones are connected to the container by engaging the cones with the groove holes of the corner members.

As such a container connector, the upper cone is mounted on the corner member of the lower container in advance, and when the containers are stacked on the lower container, the container is lowered to match the lower container, and the lower cone is automatically inserted into the groove hole of the lower container. The container is connected to each other and the containers are connected to each other. On the contrary, when the container is dismounted, there is an automatic container connector that can be automatically disconnected by pulling up the container.

As a conventional automatic container connector, for example, as shown in FIG. 10, the lower cone 10 is displaced to one side of the width direction of the groove hole C1 and received from the pedestal 11. And a protruding protrusion 13 which protrudes further in the displacement direction from the tip of the neck 12.

Then, the base 11 is slid in contact with the edge of the groove hole C1 at the time of loading of the container, and the lower inclined surface 14 for guiding the base 11 to the fitting position is provided on the side opposite to the displacement direction. It is formed in the lower portion of the fixing protrusion 13 by sliding the contact portion at the edge of the groove hole (C1) by the extraction operation during landing on the upper portion of the fixing protrusion 13 by guiding the container connector to the opposite side of the displacement direction ( The upper inclined surface 15 which moves 13 to the position which does not engage with the groove hole C1 is formed.

In the drawings, 16 represents a connecting sheet, and 17 represents an upper cone.

When the container connector is inserted into the container, when the fixed protrusion 13 is inserted into the groove hole C1 of the corner member C, the lower inclined surface 14 of the pedestal 11 slides at the edge of the groove hole C1. The fixed projection 13 is engaged with the groove hole C1 by contacting and guiding the pedestal 11 to the fitting position.

On the other hand, at the time of discharging, the fixed inclined portion 13 in that the upper inclined surface 15 of the fixed protrusion 13 is brought into sliding contact with the edge portion of the groove hole C1 and guides the container connector toward the opposite side of the displacement direction. ) Can be moved out to a position where it is not engaged with the groove hole C1.

By the way, when using the said conventional container connection tool, there exists a problem that the engagement of a container connection tool is easy to be pulled out by the inclination of the container by rolling or pitching of a ship during loading to ship.

That is, even if the container is stacked horizontally as shown in FIG. 10 (a), as shown in FIG. 10 (b), if the upper container rises obliquely upward by the hull (rolling or pitching), the wind, etc., FIG. As shown in (c), since the said fixed protrusion 13 moves to the position which is not engaged with the groove hole C1, an outer container connector tries to be pulled out from the corner member C of the lower container.

In addition, the container connector has a fixed protrusion 13 when the fixed protrusion 13 is substantially displaced from the center line of the pedestal 11 so that when the fixed protrusion 13 is inserted into the groove hole C1 of the corner member C, the container is pulled up. If (13) is displaced, it must shake horizontally, and if there is no constant gap between adjacent containers, loading cannot be performed.

At the time of discharging, the container which is pulled up because the inertia in the transverse direction remains after the fixing protrusion 13 moved to the disengaged position of the groove hole C1 by the guide of the upper inclined surface 15 is removed from the groove hole C1. There is a risk of damaging the adjacent containers due to the large shaking horizontally. In particular, when the adjacent container is a tank container, there is a risk of leaking the contained chemicals and the like.

In addition, if one side of the left and right container connector first enters the corner member (C), the other container connector does not enter, and if the container is lifted again for retry, a warping phenomenon is applied to the container connector entered first so that it does not fall out. I have a problem.

(Effects of the Invention)

According to the container connector of the present invention for achieving the first object, when the lower cone is inserted into the groove hole of the corner member during loading, the movable projection is pushed up by sliding contact with the edge portion of the groove hole, so that the container is mixed. It is possible to engage the lower cone directly in the groove hole directly with little transverse vibration.

In this case, if one side of the left and right container connector is inserted into the corner member first, or if the upper cone has a structure capable of attaching in the opposite direction, the container connector can be detached by attaching one side of the left and right container connector in the opposite direction. Even if it does not exist, the container connector can be easily detached without incorporating distortion by securing the clearance to the groove hole by incorporating the movable projection by the opening jig or the like from the other hole of the corner member.

And when the ship shakes to the displacement side after loading, since the lower base and the movable protrusion engage the edge of the groove hole with respect to the force to rise upward at an angle, the container connector does not fall out. When the ship shakes on the opposite side of the displacement side, the container connector does not fall out in that the fixing projection is engaged with the edge of the opposite side of the groove hole against the force to rise in the opposite oblique upward direction.

Further, an inclined surface is formed in the upper part of the movable protrusion by sliding contact with the edge portion of the groove hole by the extraction operation during discharging to guide the container connector toward the opposite side of the displacement direction to contact the tip of the movable protrusion with the inner surface of the groove hole. In addition, from the time when the movable protrusion is in contact with the inner surface of the groove hole, the inclined surface that slides in contact with the edge of the groove hole to guide the container connector in the displacement direction to mix the movable protrusion in contact with the inner surface of the groove hole on the top of the fixed protrusion. In this case, the upper inclined surface of the movable protrusion at the time of discharging is slid in contact with the edge of the groove hole by the withdrawal operation during discharging to guide the container connector toward the opposite side of the displacement direction so that the tip of the movable protrusion is in contact with the inner surface of the groove hole. On the other hand, the upper inclined surface of the fixed protrusion is movable From the point where the protrusion contacts the inner surface of the groove hole, the lower portion of the lower side of the container is not laterally vibrated by sliding contact with the edge of the groove hole to guide the container connector in the direction of displacement to cause the movable protrusion to contact the inner surface of the groove hole. The cone can be released just above the groove hole.

Further, the lower pedestal is secured to the fitting position of the groove hole by forming an inclined surface that slides in contact with the edge of the groove hole at the time of loading and guides the lower pedestal to the fitting position at the lower side of the lower pedestal on the opposite side of the displacement direction. Can guide you.

In addition, the upper cone protruding in the oblique direction with respect to the groove hole is fixed to the tip of the upper pedestal, and the upper cone is in contact with the rear wall of the corner member when the protrusion of the front cone is inserted into the groove hole in the opposite direction. By forming it to the length which prevents insertion of a cone, attachment of the container connector to the corner member in the front-back direction can be prevented.

Moreover, according to the container connector of this invention for achieving the said 2nd objective, the connection sheet arrange | positioned between the corner members of a stacked container and the container connector are provided in the groove hole of the upper and lower corner members, respectively, protruding from the connection sheet. A container connector having a top and a bottom pedestal to be positioned and fitted, and a top and bottom cone disposed above and below each pedestal to connect a container by engaging a groove hole of a corner member, wherein the front projection of the upper cone is a groove hole. The upper cone is opposed to front and rear with respect to the groove hole formed close to the rear wall of the corner member according to the specification in that it is formed to have a length that contacts the rear wall of the corner member and prevents the insertion of the upper cone upon insertion into the opposite direction. Direction, the front projection contacts this rear wall and the rear projection is blocked by the groove hole. Control of being so, it is possible to prevent the front and rear mounting in the opposite direction of a corner member of the container by fitting thereto.

Further, the lower cone is displaced to one side in the width direction of the groove hole and received from the lower pedestal, a fixed protrusion projecting from the distal end of the neck to the opposite side of the displacement direction, and from the neck at the proximal side than the fixed protrusion. It has a movable projection which is pushed in the direction of displacement and mixed by oscillating upward, so that when the lower cone is inserted into the groove hole of the corner member at the time of loading, the movable projection is pushed upward by sliding contact with the edge of the groove hole. The container is almost transversely vibrated and the lower cone can be engaged with the groove hole just above it.

In this case, if one side of the left and right container connector is inserted into the corner member first, or if the upper cone has a structure capable of attaching in the opposite direction, the container connector can be detached by attaching one side of the left and right container connector in the opposite direction. Even if it does not exist, the container connector can be easily detached without incorporating distortion by securing the clearance to the groove hole by incorporating the movable projection by the opening jig or the like from the other hole of the corner member.

When the ship shakes to the displacement side after loading, the container connector is not detached from the point that the lower pedestal and the movable protrusion engage the edge of the groove hole with respect to the force to rise upward at an angle. When the ship shakes to the side and the opposite side, the container connector does not fall out because the fixing projection is engaged with the edge of the opposite side of the groove hole against the force to rise to the opposite diagonally upward direction.

Further, an inclined surface is formed in the upper part of the movable protrusion by sliding contact with the edge portion of the groove hole by the extraction operation during discharging to guide the container connector toward the opposite side of the displacement direction to contact the tip of the movable protrusion with the inner surface of the groove hole. In addition, from the time when the movable protrusion is in contact with the inner surface of the groove hole, the inclined surface that slides in contact with the edge of the groove hole to guide the container connector in the displacement direction to mix the movable protrusion in contact with the inner surface of the groove hole on the top of the fixed protrusion. In this case, the upper inclined surface of the movable protrusion at the time of discharging is slid in contact with the edge of the groove hole by the withdrawal operation during discharging to guide the container connector toward the opposite side of the displacement direction so that the tip of the movable protrusion is in contact with the inner surface of the groove hole. On the other hand, the upper inclined surface of the fixed protrusion is movable From the point where the protrusion contacts the inner surface of the groove hole, the lower portion of the lower side of the container is not laterally vibrated by sliding contact with the edge of the groove hole to guide the container connector in the direction of displacement to cause the movable protrusion to contact the inner surface of the groove hole. The cone can be released just above the groove hole.

Further, the lower pedestal is secured to the fitting position of the groove hole by forming an inclined surface that slides in contact with the edge of the groove hole at the time of loading and guides the lower pedestal to the fitting position at the lower side of the lower pedestal on the opposite side of the displacement direction. Can guide you.

In addition, a rotation shaft insertion hole is formed to penetrate the connecting sheet and the upper and lower pedestals, and the rotation shaft is inserted into the rotation shaft insertion hole so as to be rotatable, and the upper cone and the lower cone are fixed to the upper and lower portions of the rotary shaft by different phases. And forming a handle inserting hole communicating with the rotating shaft inserting hole from the outer periphery of the connecting sheet, and providing a handle for rotating the rotating shaft through the handle inserting hole, thereby rotating the upper cone and the lower cone, respectively, the groove hole of the upper and lower corner members. Can be stacked to connect stacked containers.

According to the container connector of the present invention for achieving the third object, the upper cone is inserted into the groove hole of the corner member and rotated by a predetermined angle to engage the groove hole, and the groove hole from the connecting sheet at the position after this rotation. The container connector is fixed to the corner member by stopping the rotation of the upper cone by protruding the fixing pin.

At this time, the fixing pin is inserted by contact with the corner member at the insertion position of the upper cone and at the post-rotation position, the upper cone is inserted into the groove hole and automatically rotated by the spring to form a baffle. It can be fixed to a corner member only by this, and attachment of an upper cone can be performed easily by one hand by this.

In addition, when the upper cone is removed, the operation lever can be operated from the lower side of the connecting sheet, so that the fixing pin can be mixed by operating with a finger supporting the container connector, thereby removing the upper cone. It can be performed easily.

In addition, the upper cone is fixed to the upper pedestal so as to protrude in an oblique direction with respect to the groove hole, and the front cone of the upper cone is brought into contact with the rear wall of the corner member when inserted into the groove hole in the opposite direction. By forming it to the length which prevents insertion, attachment of the container connector to the corner member in the front-back direction can be prevented.
