Description

[Detailed description of the invention]

[0001]

The present invention mainly relates to a concrete block such as a consolidation block installed at a predetermined position for the purpose of preventing scouring of a bottom of a breakwater at a great depth, and a wire from a block after the installation. The present invention relates to a block suspending device for performing a removing operation by remote control.

[0002]

2. Description of the Related Art Conventionally, the work of removing the wire at the time of the installation work of the above-mentioned consolidation block is performed by a diver, but in a deep sea area, the diver's dive time becomes very short. However, there is a problem that the working efficiency is reduced.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is a block capable of remotely removing a wire at the time of installing the block in deep water. The purpose of the present invention is to provide a suspension device.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, a suspension device for a block according to the present invention includes a suspension hole having a rectangular cross section provided in the block, and a suspension jig which can be inserted into the suspension hole. The hanging hole is formed so that the upper part is formed to be small with a tapered slope, and the hanging jig is provided with an opening / closing member which can be opened and closed at the lower side on an upper side surface of a guide member having guides at four corners, for example. The guide member is provided with, for example, a truncated pyramid-shaped member capable of opening and closing the opening and closing member by vertical movement by a hydraulic cylinder or the like.

That is, by raising the truncated pyramid member with the hydraulic cylinder with the hanging jig inserted into the hanging hole, the opening / closing member is pressed against the tapered slope so that the block can be lifted. After the installation at the predetermined position, when the truncated pyramid-shaped member is lowered by the hydraulic cylinder, the opening / closing member is closed, and the hanging jig can be removed from the hanging hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a vertical sectional view showing a state of lifting a block according to an embodiment of the present invention, and FIG. FIG. 3 is a longitudinal sectional view showing a state in which the suspension device of FIG. 1 is inserted into the block, FIG. 3 is a side view of the suspension jig of FIG. 2 in the AA direction, and FIG.
5, FIG. 5 is a side view in the BB direction of FIG. 4, FIG. 6 is a side view of the plate of FIG. 3, and FIG.
It is a side view of the -C direction.

First, as shown in FIGS. 1 and 2, a suspension device of this embodiment comprises a suspension hole 2 having a rectangular cross section and provided on the upper surface of a concrete block 1 such as a consolidation block. And a hanging jig 10 as shown in FIG. Next, the upper portion of the suspension hole 2 is formed to be smaller upward with a tapered slope 3, and the upper opening is formed in a small and small shape.

The hanging jig 10 has a guide member 11 having guides for insertion at four corners thereof. A pin 12 is provided on an upper side surface of the guide member 11 as shown in FIGS. Plate 1 that is pivoted at the bottom and that can be opened and closed at the bottom
6 are arranged as opening / closing members. Further, inside the guide member 11, a truncated pyramid-shaped member 1 having a wedge portion 14 capable of opening and closing the plate 12 by a vertical movement in the directions of arrows U and D by a hydraulic cylinder 13.
5 are provided.

The truncated pyramid member 1 of the hanging jig 10
A shackle 17 to be engaged with a hook 30 such as a crane shown in FIG. Then, the hook 30 of the described FIGS. 1 and 2 per actuation of the lifting device the above structure, the hanging jig 10 such as crane
And inserted into the suspension holes 2 of the block 1, and the suspension jig 1
0 at the bottom of the suspension hole 2 and then the hydraulic cylinder 13
When the truncated pyramid-shaped member 15 is raised in the direction of the arrow U, the plate 16 is pushed and spread by the wedge portion 14 and pressed against the tapered slope 3 in the suspension hole 2 as shown in FIG. The block 1 can be lifted.

In this state, the block 1 is moved to a predetermined position by using a crane or the like, and is installed.
By lowering 3 in the direction of arrow D ,
The attached truncated pyramid-shaped member 15 descends, and as a result , the wedge portion 14 separates downward from the plate 16 as shown in FIG. 2 and the plate 16 closes, so that the hanging jig 10 can be removed from the hanging hole 2 in this state. . The hydraulic cylinder 13 is provided with a hydraulic pump 32 as shown in FIGS.
The hydraulic cylinder 13 is operated by a hydraulic device such as the above, and the vertical movement of the hydraulic cylinder 13 can be remotely controlled from the sea surface.

[0011]

According to the suspension apparatus of the concrete blanking <br/> lock of the present invention as described, according to the invention described above, since the removal of the jig hanging for hanging holes can be performed by a far隔操operation, the diver in deep sea There is no need to use it, and work efficiency is improved. Further, due to concrete blocks are bottom landing on the seabed, also loose hanging wire of the crane, since pressing the corner frustum member the opening and closing member, is safe working without departing from the hanging jig hanging hole it can. Especially the present invention
The lifting jig at the bottom of the hanging hole and move it up and down.
Activate the means to press the opening and closing member against the tapered slope
Because it was Unishi, impact of the installation of the hanging jig a hydraulic cylinder
Can be received by the strong bottom of the suspension hole.
Can withstand strong reaction forces,
Durable suspension without breaking concrete blocks
Means can be obtained .
