That is, as shown in FIG. 6, when the upper locking head 31 is in a horizontal state, the second spring pin fixing hole 32b is formed to be positioned at the center, and the stopper 32c is the receiving opening 15a. ) The position of the upper locking head 31 which is caught in the protrusion 15d formed inside to restrict the further rotation in the counterclockwise direction from the horizontal state (about 100 ° to the right from the second spring pin fixing hole) Position of the angle). In addition, a lower portion of the rotating hole 32a of the upper locking head 31 is integrally formed with a rotation shaft 37 through which an elastic spring 35 formed with one side thereof is horizontally coupled. In this case, two keys 37a and 37b are integrally formed at the lower portion of the rotation shaft 37, and the angle between the keys 37a and 37b is determined by the upper locking head 31 by the spring 51. The key engagement of the engaging hole 42 formed in the center of the lower locker 40, the key (37a, 37b) described below when the position is turned at an angle (clockwise) of about 60 degrees from the horizontal state In order to prevent interference with the jaw 42a, the vertical line X and the vertical line X are formed on the basis of the vertical line X of the upper locking head 31, as shown in FIG. The angle between the keys 37a is made of 60 °, the angle between the vertical line X and the keys 37b is made of 50 °, and the rotation axis 37 located on the opposite side of the keys 37a and 37b. The surface of is formed into a horizontal surface 37c to avoid interference with the locking pin 12 inserted into the slit groove 44 described below. It is.

In addition, the lower locking head 40 located in the inner hollow portion of the operating hole 20 has a lower locking head 43 and a locking jaw 41 inserted into the locking groove 23 of the operating hole 20. Slit groove 44 is formed in the upper portion of the locking step 41, the locking pin 12 is integrally formed on the bottom surface of the housing 10 is inserted. At this time, the slit groove 44 is formed obliquely at an angle of about 45 ~ 60 ° from the central axis (center coupling hole) of the lower rocker 40, the reason is the locking pin 12 of the housing 10 When the slit groove 44 and the interaction between the lower locking head 43 is to be locked or released in the corner casting of the container. This is made of the same structure as the automatic binding device of the conventional vessel loading container.

In addition, although the coupling hole 42 is formed at the center of the lower locker 40 to which the rotation shaft 37 of the upper locker 30 is coupled, the coupling hole 42 is completely up to the bottom surface as in the prior art. The bottom of the coupling hole 42 is formed of a closed hole, not an open through hole, and two keys 37a and 37b formed at the lower side of the rotation shaft 37 of the upper locker 30 are respectively fitted to the upper side of the coupling hole 42. A key locking jaw 42a is formed to protrude, and the horizontal cutting surface 45 is formed from one side of the key locking jaw 42a to the slit groove 44. In addition, the lower locking head 43 of the lower locker 40 is formed with a carrying hole 43a.

The relationship between two keys 37a and 37b formed below the rotation shaft 37 of the upper rocker 30 and the keying jaw 42a of the coupling hole 42 formed in the center of the lower locker 40 is as follows. It will be described in detail in the operation relationship of.

Subsequently, the coupling relationship for the automatic binding device of the ship loading container of the present invention having the above configuration will be described with reference to FIGS. 5 to 7 in the accompanying drawings.

As shown in the figure, first, the lower locker 40 is coupled to the operating port 20, and the locking jaw 41 formed at the lower locker 40 is inserted into the locking groove 23 of the operating port 20. To prevent detachment of the lower locker 40 from the actuating hole 20, and after inserting the bolt 26 into the bolt hole 25 formed in the left and right actuating holes 20a and 20b, respectively, the nut 26a. By tightening the combination of the left and right operating sphere integrally.

The rotating shaft 37 of the upper locker 30 through which the elastic spring 35 is coupled is inserted into the coupling hole 42 of the lower locker 40, which is located at the center of the operating tool 20 by the above-described coupling. And then the left and right housings 10a and 10b are then joined. One side of the elastic spring 35 is formed in a horizontal plane, the reason for this, the elastic spring 35 is the operating port (b) below the lower surface (15b) of the receiving opening (15a) formed in the housing 10 20 between the spring seating surfaces 28. At this time, as shown in Figure 5 and 6, the reinforcement for increasing the strength of the locking pin 12 from the bottom of the lower surface 15b of the receiving opening (15a) formed in the housing 10 to the upper surface of the locking pin 12 As the flesh 12a is integrally formed, it is formed in a horizontal plane so as to avoid interference with the reinforcing rib 12a and to position it closer to the reinforcing rib side. Of course, only the distal end of the locking pin 12 may be integrally formed on one side of the housing 10 without forming the reinforcing bar as in the prior art. In this case, the same circular elastic spring as in the prior art may be used. However, since the binding device of the present invention is used at the bottom of a container with a large load and at the same time is placed without a shock absorber on the concrete floor, it is possible to reinforce the locking pin 12 by the reinforcement bar 12a to increase the strength. desirable.

Hereinafter, the above-described coupling relationship will be described in more detail.

As described above, the left and right operating spheres 20a and 20b are integrally coupled to seat the protruding pieces 21 of the operating sphere 20 formed as one on the seating surface 11 of the housing 10, and at the same time the operating sphere The rotation hole 37 of the upper rocker 30 is inserted into and coupled to the coupling hole 42 of the lower rocker 40 positioned at the center of the upper locker 30, and the upper locking head 31 of the upper rocker 30 rotates. The sphere 32a is located in the receiving opening 15a of the housing 10.

Subsequently, the first spring pin fixing hole 15c formed at one side of the lower surface 15b of the accommodation port 15a is inserted into and fixed to the first spring pin 51a integrally formed with the spring 51. The second spring pin 51b positioned on the opposite side to the first spring pin 51a is inserted into and fixed to the second spring pin fixing hole 32b formed in the rotation hole 32a of the upper locking head 31.

Then, the bolt 17 is inserted into the bolt hole 16 formed in the left and right housings 10a and 10b, respectively, and then fastened with a nut 17a to integrally fix the left and right housings 10a and 10b. Let's do it.

At this time, the locking pin 12 formed on the center bottom of the right housing 10b is a slit groove of the lower locker 40 located inside the operating hole through a tapered cutout 22 formed in the right operating hole 20b. (44) More precisely, as the actuating tool 20 is pushed to the lower part of the housing 10 by the repulsive force of the elastic spring 35, the locking pin 12 is relatively, the slit groove 44 7) is positioned on the horizontal cutting surface 45 at the top (refer to FIG. 7 showing a state in which the elastic spring is omitted).

In the above configuration, the spring 51 has a tension force such that the upper locking head 31 is always obliquely positioned at an angle of about 60 ° from the horizontal state toward the first spring pin 51a (clockwise). have. The upper locking head 31 is inserted into the corner casting of the container in a horizontal state and then rotates at an angle of about 60 ° by the tension of the spring 51 so as to automatically lock the corner casting of the container. This is to make it possible. This is shown well in FIG. 8, which is also done in the same manner as in the prior art.

Further, in the above configuration, the reason why the spring 51 has a tension force such that the upper locking head 31 is always obliquely positioned at an angle of about 60 degrees from the horizontal state is because the upper locking head 31 is initially In the state (horizontal state), it is ideal to rotate at an angle of 90 ° to lock the corner casting of the container, but if the upper locking head 31 maintains only an angle of 60 ° or more in the initial state, the upper locking head 31 is This is because it can be securely locked to the corner casting of the container without the problem of deviation from the corner casting of the container.

In the present invention, the spring 51 has a tension force such that the upper locking head 31 is always obliquely positioned at an angle of about 60 ° from the horizontal state, but the tension force of the spring is the upper locking head 31. It can be positioned at an angle between 60 and 90 ° from the horizontal state.

This will be described in detail later in the operation description of the automatic binding device for a ship loading container of the present invention.

Hereinafter, the operation of the automatic binding device for a ship loading container of the present invention having the above-described coupling relationship will be described.

Figure 10a is a cross-sectional view showing an initial state of the upper locking head of the automatic binding device of the ship loading container of the present invention, Figure 10b is a top locking head of the automatic binding device of the ship loading container of the present invention to the corner casting of the container. 10 is a cross-sectional view illustrating a state in which a spring is extended when locked, and FIG. 10C is a cross-sectional view illustrating a state in which an upper locking head is locked to a corner casting of a container among automatic binding devices of a ship loading container according to the present invention. As shown in FIG. 11, when the container C1 (shown in FIG. 11) is primarily loaded on the bottom surface (not shown) of the ship, another container is placed on top of the container C1 loaded on the bottom surface of the ship loading part. (C2) is to be loaded, first, the automatic binding device of the present invention is fitted to the corner casting (61a) formed on the bottom surface of the container (C2). This will be described in detail as follows.

As shown in FIG. 10A, the operator (not shown) grasps the lower locking head 43 and then places the upper locking head 31 in the corner casting 61a formed on the bottom surface of the container C2. At this time, the upper locking head 31 is positioned in a state of being rotated at an angle of about 60 ° clockwise from the horizontal state by the tension force of the spring (51). Therefore, the operator grasps the lower locking head 43 to force the upper locking head 31 located outside the corner casting 61 a to the inside of the corner casting 61 a, and upwards (corner casting side). Add. At this time, the upper locking head 31 overcomes the tensile force of the spring 51 (spring is extended as shown in Figure 10b) and rotates (the outer surface of the upper locking head is made of a round shape without an angle that can rotate As it is positioned in a horizontal state to be able to enter the interior of the corner casting (61a), after fully entering the interior of the corner casting (61a) the external force exceeding the tensile force of the spring (51) 10C, the upper locking head 31 is automatically rotated at an angle of about 60 ° by the tension of the spring 51, thereby binding to the corner casting 61a.

Therefore, the present invention can exclude the operation that can bind the upper rocker to the corner casting of the container only when the operator has to turn the portable lever to the lower end surface of the upper rocker protruding outward through the through hole of the lower rocker as in the prior art. Will be.

FIG. 10D is a cross-sectional view illustrating an initial state when the lower locking head is locked to the corner casting of the container among the automatic binding devices of the ship loading container of the present invention, and FIG. 10E is an automatic binding device of the ship loading container of the present invention. A cross-sectional view showing a state in which the lower locking head is locked to the corner casting of the container. As shown in the drawing, when the upper locking head 31 is bound to the corner casting 61a of the container C2, the container C2 is opened. It is loaded on top of the container (C1) loaded on the bottom surface of the ship loading portion.

At this time, the lower locking head 40 enters the inside of the corner casting 61b formed at the upper part of the container C1 that is already loaded, and then the protruding jaw of the operation tool 20 on the upper surface of the corner casting 61b. (24) is caught, by the pressing load of the container (C2) the operating port 20 is inserted into the rotary shaft (34a) of the upper rocker (30) while moving upward while compressing the elastic spring (35) located Done.

At the same time, the lower rocker 40 is also moved upwards. At this time, the locking pin 12 integrally formed at one bottom of one side of the housing 10 is formed obliquely at an angle of 45 to 60 ° of the lower rocker 40. As the slit groove 44 is positioned at the tip, the slit groove 44 moves upward while torsionally rotates along the locking pin 12, and thus is fixed to one side of the housing 10. The locking pin 12 is positioned at the distal end of the slit groove 44 by the position movement of the slit groove 44. That is, since the locking pin 12 is located in the slit groove of the lower rocker 40, the lower rocker 40 moves upward while torsionally rotating. This is illustrated well in FIG. 10E.

Accordingly, the lower locking head 43 integrally formed at the lower portion of the lower rocker is simultaneously rotated to engage the corner casting 61b formed at the top of the container C1.

By the operation of the automatic binding device of the present invention as described above, the lower and upper containers are firmly bound and fixed.

On the contrary, when separating and transporting the loaded container, the upper container C2 loaded by using a crane or the like is lifted. Accordingly, since the load acting on the actuating tool 20 is removed, the actuating tool moved upwards is moved downward by the spring force of the elastic spring 35, and at the same time, the slit groove of the lower rocker 40 44 is torsionally rotated along the locking pin 12.

That is, the locking pin 12 positioned at the end of the slit groove 44 is positioned at the tip of the slit groove as in the initial state by the position movement of the slit groove 44.

Therefore, the lower locking head 43 locked to the corner casting 61b formed on the upper part of the container C2 rotates to exit from the corner casting 61b, whereby the container and the container bound together are automatically To be separated.

When dismantling the upper locking head 31 bound to the corner casting of the lifted container after separating the containers from each other as described above, when the operator holds the lower locking head 43 of the lower rocker 40 by hand and rotates The upper locking head 31 is rotated and separated from the corner casting of the container. That is, when the load of the container acting on the actuating tool 20 is removed as described above, the actuating tool 20 is moved downward by the spring force of the elastic spring 35, and thus is coupled to the actuating tool. Lower locker 40 is also moved downward along the actuation port (20). Therefore, as illustrated in FIG. 7, the two key 37a and 37b formed below the rotation shaft 37 of the upper rocker 30 have the key engaging jaw 42a formed above the coupling hole 42 of the lower rocker 40. ) Will be located on the side. At this time, when the operator holds the lower locking head 43 of the lower rocker 40 by hand and rotates it to the right, the rotation axis of the upper locker 30 on the locking jaw 42a of the lower locker 40 37) Since one key 37b of two keys 37a and 37b formed at the bottom is coupled, the upper locking head 31 which is bound to the corner casting of the container is rotated together to be separated from the corner casting of the container.
