Container connector

Technical field

TECHNICAL FIELD [0001] The present invention relates to a container connector that connects upper and lower containers to each other when stacking containers, and more particularly, an automatic container connector that can be automatically disconnected by lifting a container when unloading. It is about.

Background art

[0002] When a large number of containers are transported on a ship, containers stacked in multiple upper and lower stages are connected by a container connector so that they are loaded so as not to collapse due to the shaking (rolling or pitching) of the hull.

The container coupler is a plate-like coupling seat disposed between the corner fittings of the stacked containers, and projects from the coupling seat, and positions the container coupling fixture in the slot holes of the upper and lower corner fittings. An upper and lower pedestal to be fitted and an upper and lower cone provided at the tip of the pedestal are provided, and the containers are connected to each other when the cone engages with a slot of the corner metal fitting.

[0003] As such a container coupling tool, when the upper cone is attached to the corner metal fitting in the lower part of the container in advance and the container is stacked on the lower container, the container is lowered if the container is lowered to the lower container. The cone automatically engages with the slot of the corner metal fitting of the lower container, and the containers are connected to each other. On the contrary, when the container is landed, the connection is automatically released by lifting the container. There is an automatic container coupler that can do that.

As a conventional automatic container connector, for example, as shown in FIG. 10, the lower cone 10 is displaced to one side in the width direction of the slot C1 and hangs down from a pedestal 11, and the neck 12 The distal end force of the neck 12 is further provided with a fixed protrusion 13 protruding in the displacement direction. A lower inclined surface 14 that slides on the edge of the slot C1 when the container is loaded and guides the pedestal 11 to the fitting position is formed on the lower side of the pedestal 11 on the opposite side of the displacement direction, and the fixed protrusion The upper part of part 13 is slidably contacted with the edge of slot C1 by the pulling operation during unloading. Then, by guiding the container connector to the opposite side of the displacement direction, an upper inclined surface 15 is formed which moves the fixed protrusion 13 to the position without engaging the slot C1.

In the figure, 16 indicates a connecting seat, and 17 indicates an upper cone.

[0005] When the container connector is loaded, when the fixed protrusion 13 is inserted into the slot C1 of the corner fitting C, the lower inclined surface 14 of the base 11 is brought into sliding contact with the edge of the slot C1, By guiding the pedestal 11 to the fitting position, the fixed projection 13 is engaged with the slot C1.

On the other hand, at the time of unloading, the pulling operation causes the upper inclined surface 15 of the fixed projection 13 to slidably contact the edge of the slot C1 and guide the container connector to the opposite side of the displacement direction. It can be removed by moving to a position where it does not engage with slot C1.

[0006] By the way, when the conventional container coupler is used, there is a problem that the container coupler is easily disengaged during loading while being loaded on a ship due to the inclination of the container due to the rolling or pitching of the ship. .

That is, as shown in Fig. 10 (a), even if the containers are loaded horizontally, the upper container is tilted upwards due to the hull swaying (rolling or pitching) or wind as shown in Fig. 10 (b). As shown in FIG. 10 (c), the fixed projection 13 moves to a position where it does not engage with the slot C1, so that the outer container connector is released from the corner metal fitting C of the lower container. Try to come off.

[0007] Further, in this container connector, the fixed protrusion 13 is considerably deviated from the center line of the pedestal 11. Therefore, when the fixed protrusion 13 is inserted into the slot C1 of the corner metal fitting C, the container is lifted. Must be shaken sideways by the amount of the deviation of the fixed protrusion 13, and if there is no fixed gap between adjacent containers, the product can not be loaded.

At the time of unloading, the fixed protrusion 13 that has been moved to the position where the slot C1 is pulled out by the guide of the upper inclined surface 15 has left the slot C1, and then the lateral inertia remains. There is a risk of damaging it by hitting the container that contacts the P. In particular, when the adjacent container is a tank container, there is a risk of chemical chemicals contained in the container flowing out.

Furthermore, if one of the left and right container connectors enters the corner bracket C first, the other container connector does not enter, and if the container is lifted again for redoing, There is also a problem that the twisting phenomenon works on the container connector that has entered and cannot be removed.

In the tool, the fixed pin that abuts against the corner metal fitting at the insertion position of the upper cone and retreats, and protrudes into the slot at the position after rotation to prevent rotation, is urged toward the protruding side to the connecting seat. And an operating lever for extending the fixed pin from the fixed pin to the lower side of the coupling seat.

[0021] In this case, the upper cone is fixed to the upper pedestal so as to protrude obliquely with respect to the slot, and the front projection of the upper cone is connected to the corner fitting when inserted backward into the slot. It can be formed to a length that abuts the rear wall and prevents the upper cone from being inserted.

The invention's effect

[0022] According to the container connector of the present invention for achieving the first object, when the lower cone is inserted into the slot of the corner metal fitting during loading, the movable protrusion is located at the edge of the slot. Since it is pushed on the sliding contact and retracts, it is possible to engage the lower cone with the slot from directly above without causing the container to almost sway.

In this case, if one of the left and right container couplers enters the corner bracket first, or if the upper cone has a structure that can be mounted in the reverse direction, the left and right container couplers are reversed. Even if it is not possible to remove the container connector after it has been attached, the clearance to the slot is secured by retreating the movable protrusion from the other hole of the corner bracket with an opening jig, etc. The container connector can be easily removed without any trouble.

And after loading, if the ship shakes on the displacement side, the lower pedestal and the movable projection will engage the edge of the slot against the force of lifting up diagonally, The container connector can not be pulled out, and if the ship shakes on the opposite side of the displacement side, the fixed protrusion will be on the opposite side of the slot against the force of lifting up in the opposite diagonal direction. Since it engages with the edge, the container connector will not come off. [0023] In addition, it is slidably brought into contact with the edge of the slot by the pulling-out operation at the time of unloading, guides the container connector to the opposite side of the displacement direction, and makes the tip of the movable protrusion abut the inner surface of the slot The surface is formed on the upper part of the movable protrusion, and when the movable protrusion comes into contact with the inner surface of the slot, it slides on the edge of the slot, guiding the container connector in the displacement direction, By forming an inclined surface in the upper part of the fixed protrusion that retracts the movable protrusion that is in contact with the inner surface, the upper inclined surface of the movable protrusion is pulled to the edge of the slot by the pulling-out operation during unloading. In sliding contact, the container connector is guided to the opposite side of the displacement direction so that the tip of the movable protrusion is brought into contact with the inner surface of the groove hole, while the upper inclined surface of the fixed protrusion is formed on the movable protrusion. When contacted with the inner surface Force slidably contact the edge of the slot, guide the container connector in the displacement direction, Since the movable protrusion abutting on is retracted, the lower cone can be detached from the slot directly above without causing the container to shake substantially.

[0024] In addition, an inclined surface that slides on the edge of the slot when guiding and guides the lower pedestal to the fitting position is formed in the lower portion of the lower pedestal on the opposite side to the displacement direction, thereby lowering the lower pedestal. It can be reliably guided to the fitting position of the slot.

[0025] Further, the upper cone protruding obliquely with respect to the slot is fixed to the tip of the upper pedestal, and the front protrusion of the upper cone is fixed to the rear wall of the corner metal fitting when inserted backward into the slot. By forming the length so as to prevent the insertion of the upper cone by abutting, it is possible to prevent the container connector from being attached to the corner fitting in the reverse direction.

[0026] Further, according to the container coupling tool of the present invention for achieving the second object, a coupling seat disposed between the corner metal fittings of the stacked containers, and a projection projecting from the coupling seat The upper and lower pedestals that are positioned and fitted in the slot holes of the upper and lower corner metal fittings, and the upper and lower pedestals that are arranged on the upper and lower sides of each pedestal, and engage with the groove holes of the corner metal fittings, In the container connector provided with upper and lower cones for connecting the upper cone, the front protrusion of the upper cone is brought into contact with the rear wall of the corner metal fitting when inserted backward into the slot, thereby inserting the upper cone. Because it is formed in the length to prevent, when the upper cone is backward and forward with respect to the slot formed close to the rear wall of the corner metal according to the standard, the front protrusion comes into contact with this rear wall, This prevents the rear protrusion from being caught in the slot. More, it is possible to prevent the attachment of the front and rear opposite to the corner fittings of a container coupling. [0027] In addition, the lower cone is displaced in one of the width direction of the slot and hangs down from the lower pedestal, a fixed protrusion protruding from the tip of the neck to the opposite side of the displacement direction, and the fixed protrusion And a movable protrusion that retreats by being urged in the displacement direction from the neck at the base end side relative to the section, and retreats by swinging upward. When it is inserted into the hole, the movable protrusion slides on the edge of the slot and is pushed up and retracts.Therefore, the container is hardly shaken and the lower cone is engaged with the slot from directly above. It can be made.

And after loading, if the ship shakes on the displacement side, the lower pedestal and the movable projection will engage the edge of the slot against the force of lifting up diagonally, The container connector can not be pulled out, and if the ship shakes on the opposite side of the displacement side, the fixed protrusion will be on the opposite side of the slot against the force of lifting up in the opposite diagonal direction. Since it engages with the edge, the container connector will not come off.

[0028] In addition, it is slidably brought into contact with the edge of the slot by the pulling-out operation at the time of unloading, and guides the container connector to the opposite side of the displacement direction so that the tip of the movable protrusion comes into contact with the inner surface of the slot. The surface is formed on the upper part of the movable protrusion, and when the movable protrusion comes into contact with the inner surface of the slot, it slides on the edge of the slot, guiding the container connector in the displacement direction, By forming an inclined surface in the upper part of the fixed protrusion that retracts the movable protrusion that is in contact with the inner surface, the upper inclined surface of the movable protrusion is pulled to the edge of the slot by the pulling-out operation during unloading. In sliding contact, the container connector is guided to the opposite side of the displacement direction so that the tip of the movable protrusion is brought into contact with the inner surface of the groove hole, while the upper inclined surface of the fixed protrusion is formed on the movable protrusion. When contacted with the inner surface Force slidably contact the edge of the slot, guide the container connector in the displacement direction, Because the movable protrusion that contacts is retracted, the container can be lowered with almost no side shake. The part cone can be detached from the slot right above.

[0029] In addition, an inclined surface that slides in contact with the edge of the slot at the time of loading and guides the lower pedestal to the fitting position is formed on the lower portion of the lower pedestal on the side opposite to the displacement direction, thereby lowering the lower pedestal. It can be reliably guided to the fitting position of the slot.

[0030] In addition, a rotary shaft insertion hole that penetrates the coupling seat and the upper and lower pedestals is provided, and the rotation shaft is rotatably fitted in the rotation shaft insertion hole. The lower cones are fixed in different phases, a handle insertion hole communicating with the rotation shaft insertion hole is formed in the connecting seat from the outer periphery, and the rotation shaft is rotated through the handle insertion hole. By providing the hand nore, it is possible to connect the stacked containers by sequentially engaging the slots of the upper and lower corner metal fittings while rotating the upper cone and the lower cone respectively.

[0031] According to the container connector of the present invention for achieving the third object, the upper cone is inserted into the slot of the corner metal fitting and is engaged with the slot by rotating a predetermined angle. Then, the fixing pin protrudes from the connecting seat into the slot at the position after the rotation, thereby stopping the rotation of the upper cone and fixing the container connecting tool to the corner fitting.

At this time, the fixing pin retreats by contacting the corner metal fitting at the insertion position of the upper cone, and automatically protrudes into the groove hole by the spring at the position after the rotation, so that the upper cone It can be fixed to the corner metal fitting by simply inserting it into the slot and rotating it, so that the upper cone can be easily attached with one hand.

In addition, when removing the upper cone, the operating lever can be operated from the lower side of the coupling seat, so that the fixing pin can be retracted by operating with the fingers supporting the container coupling tool. Removal can be easily performed with one hand.

[0032] In addition, the upper cone is fixed to the upper base so as to protrude obliquely with respect to the slot, and the front protrusion of the upper cone is connected to the corner metal fitting when inserted into the slot in the reverse direction. By forming the length so as to contact the rear wall and prevent the upper cone from being inserted, it is possible to prevent the container connector from being attached to the corner metal fitting in the reverse direction.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the container connector of the present invention will be described with reference to the drawings. Example 1 1 to 4 show a first embodiment of the container connector of the present invention.

This container connector is positioned between the connecting metal fittings C of the stacked containers, and the container connecting tools are positioned in the slot C1 of the upper and lower corner metal fittings C. The upper pedestal 2 and the lower pedestal 3 that are fitted together, and the upper cone 4 and the upper cone 4 that project from the upper pedestal 2 and the lower pedestal 3 and connect the containers by engaging with the slot C1 of the corner fitting C. With a lower cone 5.

[0037] The connecting seat 1 is made of a plate-like metal formed to have a predetermined thickness, and an upper base 2 and a lower base 3 are integrally projected vertically.

Note that the shape of the connecting seat 1 is not particularly limited. It can also be formed as a triangular or trapezoidal ridge.

[0038] The upper pedestal 2 has a substantially diamond-shaped cross section as shown in FIG. 4 and is provided to the left and right within the slot C1 of the corner fitting C so as to be rotatable within a predetermined range and provided to the coupling seat 1. By causing the fixing pin 6 to protrude into the slot C1, the upper cone 4 can be fixed at the position after rotation where it engages with the slot C1.

As shown in FIG. 2, the fixing pin 6 is urged in the protruding direction by the spring 61, and the shaft 6

2 is pivotally supported by the connecting seat 1, and it can be operated by operating the lever 63 from the lower surface side of the connecting seat 1.

[0039] As shown in Fig. 1 or Fig. 6 (c), the lower pedestal 3 is formed so that its upper part fits substantially in the slot C1 of the corner fitting C, and at its lower part, On the opposite side of the displacement direction, an inclined surface that slides into contact with the edge of the slot C1 during loading and guides the lower pedestal 3 to the mating position.

31 is formed.

The inclined surface 31 (Fig. 11 (a)) that guides the lower pedestal 3 to the mating position is shown in Figs. L l (b) to (d

The guide surfaces 31B, 31C, and 31D may be configured by curved surfaces as shown in FIG.

[0040] As shown in Figs. 4 to 5, the upper cone 4 is fixed to the tip of the upper base 2 so as to protrude obliquely with respect to the slot C1 at the fixed position. The front protrusion 41 has a length that prevents the upper cone 4 from being inserted by abutting against the rear wall C2 of the corner fitting C when inserted backward into the slot C1. The slot CI of the corner bracket C is formed at a position close to the rear wall C2 of the corner bracket C according to ISO standards, and can be mounted when the upper cone 4 is in the correct orientation as shown in Fig. 5 (a). As shown in Fig. 5 (b), when the upper cone 4 is reversed in the front-rear direction, the front protrusion 41 contacts the rear wall C2 of the corner fitting C, so the rear protrusion 42 is the slot C. In this case, the container connector is prevented from being attached to the corner fitting C in the reverse direction.

[0041] The lower cone 5 is displaced to one side in the width direction of the slot C1 and hangs from the lower pedestal 3, and a fixed protrusion 8 that protrudes from the tip of the neck 7 to the opposite side of the displacement direction, The movable projection 9 is provided with a movable projection 9 that protrudes by being biased in the displacement direction from the neck portion 7 on the base end side with respect to the fixed projection 8 and retreats by swinging upward.

The neck 7 is formed to be thin enough to subtract the protruding width of the movable protrusion 9 from the lower pedestal 3 and hangs down from one side of the lower pedestal 3.

As shown in FIG. 1, the lower part of the movable protrusion 9 is pivotally attached to the vicinity of the tip of the neck 7 by a shaft 91, and the upper part is urged outward by a spring 92.

As shown in FIGS. 7 (a) to 7 (b), the upper part of the movable protrusion 9 is slidably contacted with the edge of the slot C1 by the pulling operation during unloading, and the container connector is placed on the opposite side of the displacement direction. An inclined surface 93 is formed to guide the movable projection 9 so that the tip of the movable projection 9 abuts against the inner surface of the slot C1.

The movable protrusion 9 also has an inclined surface 94 at the bottom, and at the position where the movable protrusion 9 protrudes most, the width combined with the neck 7 is close to the width of the slot C1 of the corner fitting C. Yes. Since the movable protrusion 9 is fitted in a recess formed in the neck 7 while being pressed by the spring 92, the movable protrusion 9 can swing while maintaining its position even if the shaft 91 is omitted. It is possible.

[0043] At the upper part of the fixed protrusion 8, as shown in FIG. 7 (b), the force at which the movable protrusion 9 abuts against the inner surface of the slot C1 also slides on the edge of the slot C1, and the container connector Is formed in an inclined surface 81 for retracting the movable protrusion 9 abutting against the inner surface of the slot C1. The fixed protrusion 8 also has an inclined surface 82 at the bottom, and the width of the fixed protrusion 8 and the neck 7 is close to the width of the slot C1 of the corner fitting C at the position where the fixed protrusion 8 protrudes most. ing.

[0044] Next, the operation of the container connector of the present embodiment will be described. As shown in FIG. 6, when the container connector is loaded, when the lower cone 5 is inserted into the slot C1 of the corner fitting C, the movable protrusion 9 is slidably contacted with the edge of the slot C1 and pushed upward. Therefore, the lower cone 5 can be engaged with the slot C1 from directly above without causing the container to almost roll sideways.

In this case, by forming an inclined surface 31 that slides on the edge of the slot C1 during loading and guides the lower pedestal 3 to the fitting position on the lower side of the lower pedestal 3 on the opposite side of the displacement direction, As shown in FIGS. 6B to 6C, the lower pedestal 3 can be reliably guided to the fitting position of the slot C1.

[0045] Also, at the time of loading, one of the left and right container couplers enters the corner fitting C first, or one of the left and right container couplers is attached in reverse and the container coupler is removed. Even if it becomes impossible, for example, using an opening jig 20 as shown in FIG. 9, insert the operation piece 20a of the opening jig 20 into the other hole of the corner fitting C, and Rotating operation part 20b is rotated by operating piece 20a with support part 20c formed so as to rotate freely at the distal end with support part 20c formed to rotate freely around corner hole C. By retracting 9, the clearance for the slot C1 can be secured, and the container connector can be easily removed without causing the twisting phenomenon.

[0046] After loading, as shown in Fig. 7 (a), when the ship shakes on the displacement side, the lower pedestal 3 and the movable protrusion against the force P1 that is going to rise obliquely upward. Since the portion 9 engages with the edge of the slot C1, the container connector cannot be removed.

In addition, as shown in Fig. 7 (b), when the ship shakes on the opposite side to the displacement side, the fixed projection 8 has a slot C1 against the force P2 that is going to float up diagonally in the opposite direction. Since the opposite edge of the container is engaged, the container connector does not come off.

[0047] Further, during unloading, as shown in FIGS. 8 (a) to 8 (b), the upper inclined surface 93 of the movable protrusion 9 is brought into sliding contact with the edge of the slot C1 by the pulling-out operation during unloading. The connector is guided to the opposite side of the displacement direction, and the tip of the movable protrusion 9 is brought into contact with the inner surface of the slot.

Then, as shown in FIGS. 8 (b) to (c), the upper inclined surface 81 of the fixed projection 8 slides on the edge of the slot C1 from the time when the movable projection 9 contacts the inner surface of the slot.

Example 3

FIGS. 14 to 17 show a third embodiment of the container connector of the present invention.

This container connector has the same basic structure as the container connector of the first embodiment. As shown in FIG. 14, the fixing pin 6 is pivotally supported on the connecting seat 1 by a shaft 62 while being urged in a protruding direction by a spring 61. Retreat by operating the operation lever 63 extended to the side.

The fixed pin 6 has its tip positioned obliquely above the shaft 62, and when this tip abuts the lower surface of the corner fitting C, that is, the edge of the slot C1, at the insertion position of the upper cone 4. Pressed in to retreat.

Then, at the position after the rotation of the upper cone 4, the edge force of the slot C1 is released and enters the slot C1, and the spring 61 automatically protrudes into the slot C1 to prevent rotation.

Further, the operation lever 63 is positioned by a positioning pin 64, and is provided so that the fixing pin 6 can be retracted by pushing it forward with the thumb of the hand supporting the container connector.

[0062] Next, the operation of the container connector of the present embodiment will be described.

The container connector is attached by first inserting the upper cone 4 into the corner fitting C of the container that has been lifted.

That is, the upper cone 4 is inserted in accordance with the slot C1 of the corner fitting C, and is engaged with the slot C1 by rotating it by a predetermined angle, and is fixed from the connecting seat 1 to the slot C1 at the position after this rotation. By protruding the pin 6, the rotation of the upper cone 4 is stopped, and the container connector is fixed to the corner fitting C.

At this time, the fixing pin 6 retreats by coming into contact with the corner fitting C at the insertion position of the upper cone 4 and automatically protrudes into the slot C1 by the spring 61 at the position after rotation to prevent it from rotating. Therefore, the upper cone 4 can be fixed to the corner fitting C simply by inserting the slot C1 into the slot C1 and rotating it, so that the upper cone 4 can be easily attached with one hand.

Further, when removing the upper cone 4, the operation lever 63 can be operated from the lower side of the coupling seat 1. For example, the fixing pin 6 is retracted by pushing the operation lever 63 with the thumb of the hand supporting the container coupling tool. This allows the upper cone 4 to be easily removed with one hand.

[0063] Further, the upper cone 4 protruding obliquely with respect to the slot C1 is fixed to the tip of the upper base 2 In addition, the front protrusion 41 of the upper cone 4 should be formed to a length that prevents the insertion of the upper cone 4 by abutting against the rear wall C2 of the corner fitting C when inserted in the reverse direction into the slot C1. This prevents the container connector from being attached to the corner fitting C in the reverse direction.
