Description

[Detailed description of the invention] The present invention relates to a coupler for lifting and transportation in which a locking rod for locking a wire for hanging a load automatically comes out and disappears when the load is lifted from the ground or placed on the ground. It is something.

Conventionally, a wire is hung on a load and the wire is hooked to a hook of a crane or the like to lift and transport the load, but hooking the hook with the wire or removing the wire is done manually. is the current situation.

In particular, when a plurality of wires are hung on one hook, it is difficult to remove them.

In view of the above-mentioned points, the present invention has been made with the object of providing a coupler for lifting and transportation, which can be automatically removed when multiple wires can be hung thereon. The structure consists of a covered cylindrical body with a plurality of upwardly inclined through holes provided on the outer circumferential surface.
A mounting plate having a wire locking rod to be housed in the inclined through hole on the outer periphery is housed so as to be movable up and down, and is mounted on the lid of the cylindrical body so as to be able to move up and down by sandwiching the lid. A sliding rod provided with a stopper portion is movable up and down and installed through the sliding rod, the mounting plate is fixed to the lower end of the sliding rod, and a support portion supported by a hook of a crane or the like is provided at the upper end. This is a characteristic feature.

Next, embodiments of the present invention will be described with reference to the drawings.

1 is a bottomless cylindrical body with a stepped hole 1a formed inside; 2
3 is a lid integrally formed with the main body 1; 3 is a plurality of inclined through holes formed through the lower peripheral wall of the main body 1; There are 3 to 4 locations.

Reference numeral 4 denotes a mounting plate for a locking rod that is loosely inserted into the main body 1 from below, and a wire is attached to the mounting plate 4 at a portion corresponding to each inclined through hole 3 of the main body 1 on the outer periphery of the mounting plate 4. Latching rod 5
are each attached to a shaft.

Therefore, each of the above-mentioned locking rods 5 has a mounting plate 4 with a stepped hole 1a.
The length of the rod is adjusted to such an extent that the tip 5a of the rod does not protrude from the through hole 3 to the outside of the main body 1 when the rod is located at the lower part of the rod.

Reference numeral 6 denotes a sliding rod to which the mounting board 4 is fixed at the lower end, and whose upper end is attached to the main body 1 by passing through the lid part 2 from inside the stepped hole 1a so as to be movable up and down. An annular locking member 7 to be hooked to the hook is provided, and a flange-shaped sliding stopper 6at6b is provided in the middle to sandwich the lid portion 2 and with a distance sufficiently larger than the thickness of the lid portion 2. 1 to 7 above constitute an example of the coupler of the present invention.

Next, an example of how the above coupler is used will be explained.

First, when the coupler of the present invention is placed on the ground etc. in the attitude shown in Fig. 1, the sliding rod 6 is in a position lowered to the upper strapper 6a due to the weight of itself and the attached members. , each of the locking rods 5 is in a state where its tip side 5a is sunk into each of the through holes 3.

On the other hand, the locking member 7 of the coupler of the present invention in the above state is
When the main body 1 is hung on a hook of a crane or the like and lifted up, the sliding rod 6 moves upward until the lower stopper 6b of the main body 1 comes into contact with the back surface of the lid part 2 of the main body 1, while the main body 1 remains on the ground.

When only the sliding rod 6 moves upward, the mounting plate 4 at the lower end also moves at the same time, but at the time of this movement, each of the locking rods 5 provided on the mounting plate 4 is closed. The distal end side 5a is guided by each inclined through hole 3 and protrudes from the hole 3 to the outside of the main body 1.

(See Fig. 2) Therefore, in the coupler of the present invention, when each of the locking rods 5 is in the state shown in Fig. 2, the wire of the wired load is hooked to each of the locking rods 5 and supported. , operate a crane or the like to lift and transport the load to a predetermined position, lower the load to the ground, etc. at the predetermined position, and when the lower surface of the coupler of the present invention is brought into contact with the main body 1 on the ground, etc., the sliding rod 6 descends inside the main body 1 due to its own weight, and each locking rod 5 sinks into its through hole 3. Therefore, each locking rod 5 can be hooked to each wire without the need for manpower. It is very convenient because it can be removed from the rod 5.

In addition, since the coupler of the present invention has a plurality of locking rods 5, it is possible to suspend multiple loads at the same time and remove the wires of the loads at the same time, which greatly contributes to streamlining the lifting and transportation work. Furthermore, since the hanging rod 5 is rod-shaped and is provided facing upward, it is relatively easy to hang the luggage with a wire, which facilitates the rationalization described above.

The present invention is as described above, and is extremely useful as a coupler that connects the hook of the crane to a wire hung on the load when the load is lifted and transported by a crane or the like.
