Description

[Detailed Description of the Invention] The present invention relates to an improvement of an eye plate used when lifting objects such as structures, single objects, or girders for construction with a large weight using wires or chinos.

Conventionally, when hoisting the above-mentioned object with a crane, a suitable number of eye plates with holes for shackle pins provided at appropriate locations on the top of the hoisted object were usually attached to the shackle at the end of the lifting side of the crane. It is fitted with a nut.

Conventionally, when making this connection, it is difficult to fit and tighten the large, heavy shackle, which swings around the crane suspension base via a wire, and the holes or hole centers of the aforementioned eye plate. It required multiple artificial implants.

Also, when removing the shackle, the weight of the shackle will hang on the pin,
This was time-consuming due to frictional forces and other factors.

The work is particularly difficult at sea or underwater.

The present invention is characterized by a shackle support member that supports the shackle during shackle attachment/detachment protruding below the shackle attachment bolt hole provided on the eye plate, and its purpose is to attach the shackle to the eye plate. It is an object of the present invention to provide an eye plate which eliminates the problems of the conventional art by having an extremely simple structure in which a shackle support member that receives the weight of the shackle is protruded below a bolt hole.

Since the present invention is constructed as described above, when the shackle is attached to the eye plate, the shackle is supported by being placed on the shackle support member described above, so that the shackle attached to the shackle and the eye plate is Not only is it easier to align the shackle with the eye plate, but when the shackle is removed from the eye plate, the weight of the shackle is supported by the support member, so bolts and nuts can be installed quickly and smoothly.

Therefore, in the present invention, the shackle can be safely attached to and detached from the eye plate, and the work efficiency can be improved.

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

In this embodiment, a flat par 7 constituting a shackle support member is welded or glued to a well-known eye plate 4, and the shackle 2 is suspended from a bolt hole of the eye plate 4 by a wire 1 from a crane or the like and swings. When aligning the holes and fitting with the bolts 5 and nuts 6, the shackle 2 is cleared or placed on the flat par 7 to stop the swinging.

As a result, the heights of the holes in the shackle 2 and the holes in the eye plate 4 match, making alignment very easy.

Therefore, when moving the shackle 2 to the flat par 7, it is easy to aim at the approximate position.

In the above embodiment, the flat par 7 is provided horizontally, but
In order to facilitate alignment of the shackle or the shackle hole with the eye plate hole, it may be provided diagonally as shown in Figure 3.The flat parr 7 described above may also be replaced with round bars 8, 8 as shown in Figure 4. .

Further, in each of the embodiments described above, the eye plate 4 is provided upwardly of the suspended object, but it may be provided so as to protrude toward the outside of the suspended object as shown in FIG.

In addition, in order to align the hole center of the shackle 2 drilled by the flat bar 7 with the hole center of the eye plate so that the bolt can be inserted under almost no load, the outer end of the bonded flat bar should be hammered. You can easily make fine adjustments by simply tapping the button.

In each embodiment configured in this way, the shackle 2
When attaching the shackle to the eye plate 4, the dead weight of the shackle 2 can be held by the flat par 7, and it is only necessary to adjust the S in the horizontal direction and align the holes. The time required for hole alignment can be greatly reduced.1
The shackle 2 can be easily attached by a person.

Furthermore, since the flat parr 7 is loaded with its own weight during removal, the bolt 5 is not subjected to excessive force and can be removed smoothly.

In particular, this embodiment not only reduces the effort required for underwater work, that is, when attaching and detaching the shackle underwater, but also allows the work to be carried out by one person with peace of mind, so that it can exhibit excellent practical effects.
