Description

[Detailed description of the invention] [Industrial field of application] The present invention is a method of inserting the main body of the lifting fitting into the corner fittings provided at the four corners of the top surface of the container when lifting and transporting the container during cargo handling and transportation work at ports. ,
Rotate 90 degrees and hold that rotation position for example 4
A container suitable for so-called angle lifting, where the upper ends of wire ropes are concentrated in one place and lifted using a crane, or for lifting the container using four ropes and a balance. This relates to hanging fittings.

[Problems that conventional technology and ideas try to solve]

As shown in FIG. 5, corner fittings 2 are generally attached to the four corners of the upper surface of the container 1.
Oval holes 2a and 2b are bored in the top and side surfaces of the.

Conventionally, when lifting and transporting the container 1, the hooks 3 attached to the lower ends of the four ropes R are inserted through the oval holes 2b on the side of each corner fitting 2, and the hooks 3 are inserted into the oval holes 2a. The tip of the hook 3 is put out at the top, and the hook 3 is hooked to the edges of both oval holes 2a and 2b to lift it up (when the hook 3 is inserted from the oval hole 2a and taken out from the oval hole 2b, The hook 3 may come off from the oblong hole 2b due to impact being applied during lifting or bending load or twisting from the four ropes R being applied to the hook 3).

Therefore, hooking the hook 3 to the corner fitting 2,
Alternatively, during the removal work, it is necessary to provide an appropriate space between adjacent containers 1, which is disadvantageous in that the loading area inside the ship cannot be used effectively.

[Means for solving problems]

The container hanging fitting of the present invention is a container hanging fitting that is inserted into and connected to the corner fittings provided at the four corners of the upper surface of the container, and is lifted and transported using four ropes. a main body that is inserted into the main body and can be rotated horizontally by 90 degrees; a cylindrical column that projects vertically from the center of the upper surface of the main body and has a key along the outer peripheral wall perpendicular to the longitudinal direction of the main body; A key groove is formed to fit into the key, and the key groove is slidably fitted in the axial direction of the cylindrical part so as to be orthogonal to the longitudinal direction of the main body part, and a handle is fixed to the upper surface of the main body part. A substantially plate-shaped slider that can be freely inserted into a circular hole, and a suspension ring that is fixed at a predetermined angle displacement with respect to the central axis of the slider so as to face each other in a diagonal direction, and that has a hook hole that is substantially perpendicular to the diagonal line. arcuate surfaces are formed on the upper surface of both longitudinal ends of the main body and the lower surface of the main body, the height of the main body is set approximately equal to the inner wall height of the corner fitting, and the thickness of the slider is We adopted a method of setting the material thickness to be the same as or slightly larger than the material thickness of the corner fittings.

Therefore, if the main body of the hanging bracket is inserted into the corner bracket through the oblong hole on the upper surface of the corner bracket and rotated 90 degrees, the slider will fit into the oblong hole and cannot rotate, and the main body will also close to the corner. Since it is held perpendicular to the oblong hole within the fitting, the hanging fitting is fixed within the corner fitting, and the hanging rings at the four corners are installed facing directly to avoid being affected by the bending load of the rope. It's a thigh. Therefore, the load and twist from the hanging ropes are not transmitted to the hanging fittings, and even if a bending load is applied to one rope, the four ropes cancel each other out, allowing the container to be held horizontally in the specified location. Can be transported.

〔Example〕

Examples of the hanging fitting according to the present invention are shown in Figures 1 to 4.
This will be explained with reference to the figures.

FIG. 1 shows a perspective view of the hanging fitting, and in the figure,
The hanging fitting 4 includes a main body 5 that is inserted into and removed from the corner fitting 2 through the oblong holes 2a of four corner fittings 2 provided at the four corners of the container 1, and a main body 5 that projects perpendicularly to the center of the upper surface of the main body 5. A cylindrical portion 7 having a key 6 extending perpendicularly to the longitudinal direction of the main body portion 5 along the outer circumferential wall, and a key groove 8a that fits into the key 6 are formed, A roughly plate-shaped slider 8 that can be slid in the height direction and whose installation height can be adjusted.
The pin 9 is fitted onto the top of the cylindrical portion 7, and is displaced by a predetermined angle α with respect to the longitudinal center line _O1 of the slider 8, thereby allowing the pin 9 to be inserted from the four ropes for hanging as shown in FIG. Diagonal lines T ₁ and T ₂ are formed at the top of the cylindrical portion 7 so as not to receive bending load or twisting.
The hanging rings 10 are fixed so as to face each other in the direction.

Therefore, in order to lift and transport the container 1, there are four corner fittings 2 provided at the four corners of the container 1.
Shackles (not shown) are attached to the lower ends of four ropes corresponding to the above-mentioned hanging ring 1.
In addition, the hook hole 10a provided in the hook hole 10a provided in the container 1 has its central axis _O2 located at the four corners of the container 1; the diagonal line _T1 connecting each other; Since it faces directly by being substantially orthogonal to T ₂ , the hooking holes 10a, 10a;
When the container 1 is hung with a rope by hooking the shackle inside 10a, 10a, the bending load and twist from the rope are not transmitted to the hanging ring 10. Even if a bending load is applied to one of the four ropes, the four ropes cancel each other out. As a result, the container 1 can be lifted and transported horizontally.

The lower surface of the main body 5 is formed into an arcuate surface 5a, and the upper surface of both longitudinal ends of the main body 5 is formed into arcuate surfaces 5b, 5c.
The top surfaces of b and 5c are the protruding flat surfaces 5d of the cylindrical portion 7.
The arcuate surface 5 is set to the same plane as the flat surface 5d.
The distance from a to the top surface is set approximately equal to the distance between the upper inner wall and lower inner wall of the corner fitting 2.

Further, the outer shape of the slider 8 is formed into an elongated plate shape so as to fit into the oblong hole 2a of the corner fitting 2, and its thickness is set to be the same as or slightly larger than the material thickness of the corner fitting 2. A handle 11 is fixed to the inner end on the longitudinal center line of the slider 8 and is bent into two stages so as not to touch the shackle attached to the lower end of the rope when the slider 8 is moved upward. ing.

Note that the hanging ring 10 can be fixed to the top of the cylindrical portion 7 not only by the pin 9 but also by welding.

Next, a procedure for attaching or removing the hanging fitting 4 having the above structure into the corner fitting 2 will be explained.

First, for installation, (a) Hold the hanging ring 1 and insert the main body 5 into the corner fitting 2 through the oblong hole 2a as shown by the solid arrow in FIG.

Initially, the slider 8 slides down the cylindrical part 7 by fitting the key 6 and the keyway 8a, and is in a state of contacting the flat part 5d of the main body part 5.
(For convenience of explanation, the slider 8 is shown above the flat part 5d in the drawing.) The main body part 5 is inserted into the corner fitting 2 as described above, and the top surface of the circular arc surface 5a on the lower surface of the main body part 5 is placed at the corner. When the slider 8 contacts the bottom surface of the metal fitting 2, the slider 8 contacts the upper surface of the oblong hole 2a orthogonally according to the setting conditions described above.

(b) Next, hold the handle 11 and rotate the slider 8 by 90 degrees in the direction of the solid arrow.

As shown in FIG. 3, as the slider 8 rotates 90 degrees, the key 6 and the keyway 8a fit together, so that the main body 5 has an arcuate surface 5a on its lower surface and arcuate surfaces 5b, 5c on the upper surface of both ends. Due to the sliding of each top surface of the corner fitting 2, the inside of the corner fitting 2 is smoothly rotated 90 degrees without any frictional load and without damaging the inner surface of the corner fitting 2, and the corner fitting 2 is in a state perpendicular to the oblong hole 2a, which prevents shocks, etc. Even if the corner metal fitting 2 is applied, no rattling occurs and the corner metal fitting 2 does not come out.

Further, the slider 8 directly faces the oval hole 2a, slides down the columnar part 6, and fits into the oval hole 2a.

As a result, the slider 8 becomes unable to rotate, and the main body 5 that is key-fitted with the slider 8 is also kept rotated by 90 degrees, so that the hanging bracket 4 is fixedly attached to the corner bracket 2. It turns out.

Then, when the hanging fittings 4 are completely installed, each hanging ring 10 is connected to the hanging ring 10 and the slider 8 as described above.
Since the central axis O ₁ in the longitudinal direction has a displacement angle α, the hanging rings 10 in the diagonal lines T _{1 and} T ₂ directly face each other, _and the hanging holes 10
a, 10a; 10a, 10a intersect at a substantially right angle and face each other directly.

Next, to remove the hanging fitting 4, pull up the slider 8 by holding the handle 11 to disengage it from the oval hole 2a, and then rotate the slider 8 by 90 degrees to move the main body 5 into the oval hole 2a. Directly facing the handle 11
Alternatively, hold the hanging ring 10 and pull it up to remove the main body 5 from the corner fitting 2.

〔effect〕

The present invention has the following effects.

(a) Insert the main body of the hanging bracket into the corner bracket through the oblong holes on the top of the corner bracket provided at the four corners of the top of the container, rotate it 90 degrees, and at the same time fit the slider into the oblong holes to remove the hanging bracket. Since it is fixedly attached to the corner fitting, the shackle attached to the lower end of the lifting rope can be hooked on and removed from the top of the container, eliminating the need for gaps between adjacent containers. , it is possible to make effective use of the container loading area, and it is possible to lift and lift the containers in an adjacent state.
Moreover, the work of attaching and removing the hanging fittings is extremely easy.

(b) An arcuate surface is formed on the upper surface of both longitudinal ends of the main body of the hanging fitting, and the hanging ring is displaced from the slider by a predetermined angle, so that when the hanging fitting is installed, the hanging ring and the hanging ring on the diagonal of the top surface of the container are Since the hook holes provided in the hanging ring are directly facing each other, there is no bending load or twisting from the rope.
Angle hanging is possible using four ropes,
Furthermore, the container can be lifted and transported horizontally without the need for a hanging scale or the like.
