DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic cylinder mounted on a barge so as to swing, a lower end of the spat landing on the seabed by a pad elevating device installed on the float, and a hydraulic cylinder mounted between the float and the barge. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barge moving device provided with a spat elevating device capable of moving a barge when activated.

[0002]

2. Description of the Related Art Conventionally, a spat of this type is used exclusively for positioning a barge. In many cases, a barge is moved by using a winch to wind a wire, a rope, a chain, or the like around a bow of the barge in principle. The stern side has been operated in a maneuvering manner of loosening.

An anchor is attached to the tip of the wire as a weight, and at least four wires several times as long as the barge project from the barge.

[0004] Conventional spats are used for positioning the barge as described above, and most of them are fixed on the barge with the spat winch, so that they have a drawback that they can only move up and down.

[0005] In addition, the winch has drawbacks such as that it is impossible to hit even a wire or chain for maneuvering at a work place where the seabed is too shallow, and the anchor cannot be moved to a predetermined position by a boat. Moving was extremely difficult.

As described above, each of the barges has several times the length of the wire, rope or chain for maneuvering the barges, and at least four of them are overhanging. At work sites with a large number of
At present, overhanging wires, ropes, or chains are impeding the work of other barges (such as maneuvering and changing anchors) and adversely affecting the operation of other barges. Development was requested.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks of the related art, and an arbitrary barge is provided without using a winch, a wire, a rope, a chain, or the like. The present invention proposes a wireless barge moving device that can be moved to a position.

That is, the present invention is configured such that one end of a float provided with a spat and the elevating device of the spat is connected to a barge via a connection part, and the float can be swung up and down around the connection part. The float and the barge are connected by a hydraulic cylinder and the spat is tilted back and forth through the float by the operation of the cylinder through the float. The present invention relates to a mobile device.

[0009]

According to the present invention, only the operation amount of the hydraulic cylinder (the amount of the inclination of the float) is set with the tip of the spat driven into the sea floor as a fulcrum, without using a wire, a rope, a chain, etc. by a winch as in the conventional art. The barge can be moved in proportion to the length of the spat. In this case, the moving distance is short at a shallow place, and the moving distance is long at the deep place because the same cylinder is used.

[0010] If the movement of the barge is within the range of the stroke of the hydraulic cylinder, the spat lands on the seabed, so that any position can be selected. Next, embodiments of the present invention will be described with reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view of a barge with one float attached, FIG. 2 is a plan view of a barge with two floats attached, and FIG. 3 is a mount with two floats FIG. 4 is a side view of the barge when the spat is fixed, FIG. 5 is a side view of the barge before moving the barge when operating the hydraulic cylinder, and FIG. It is side surface explanatory drawing after the barge movement at the time of operating.

In the drawing, reference numeral 1 denotes a work boat, 2 denotes a spat which can be raised and lowered, 3 denotes an elevating device for raising and lowering the spat 2, 4 denotes a connecting portion serving as a fulcrum when the spat 2 swings, and 5 denotes the spat. A float provided with a lifting device 3, one end of the float 5 is connected to the barge 1 via the connection part 4, and a hydraulic cylinder 6 is provided to connect the barge 1 and the float 5. Have been.

As shown in FIG. 1 or FIG. 2, one or a plurality of floats 5 are mounted on the barge 1 so as to be swingable toward the bow or stern side. Are installed on both sides of the barge 1 as shown in FIG.

The float 5 is installed such that the hydraulic cylinder 6 does not interfere with the barge 1 within the stroke range of the hydraulic cylinder 6 even when the hydraulic cylinder 6 is operated with the connecting portion 4 as a fulcrum.

[0015] Float 5 equipped with spat lifting device 3
Is connected to the barge 1 by an axis of the connecting portion 4, and the float 5 swings around the axis of the connecting portion 4 as a fulcrum.

The hydraulic cylinder 6 swings the float 5 vertically about the axis of the connecting portion 4 as a fulcrum. The operation of the hydraulic cylinder 6 causes the spat 2
The angle is determined.

The hydraulic cylinder 6 in the state shown in FIG.
Is at half the full stroke length. Normally, when the barge 1 is positioned by the spat 2 in the state shown in FIG. 4, a large force may be applied to the hydraulic cylinder 6. Therefore, the float 5 and the barge 1 are fixed by providing a mechanical lock (not shown). It is desirable to do.

Next, a method of moving the barge 1 will be described with reference to the barge apparatus of FIG. 1 in which one float 5 is provided on the stern side and two spats 21 and 22 are provided on the bow side. Will be described with reference to FIGS.

In the barge 1 provided with one float 5 as shown in FIG. 1, when the spat 2 provided on the float 5 does not land on the seabed as shown in FIG. The two spats 21 and 22 are both landed, and are in a fixed state to position the barge 1.

In this state, for example, when the hydraulic cylinder 6 installed between the float 5 and the barge 1 is reversely operated and the rod is retracted, the float 5 is set at a predetermined angle in the direction of sinking into the sea around the connection portion 4. The float 2 is rotated to tilt the spat 2 provided on the float 5 backward, and then the lifting device 3
Is driven to lower the spat 2 to pierce the lower end of the spat 2 into the seabed (see FIG. 5). Note that the hydraulic cylinder 6 can also be used as a hydraulic source of the lifting device 3.

Then, next, the spats 21 on both sides of the bow,
22 is lifted by other lifting devices 3 and 3 provided therewith to be separated from the seabed (this is referred to as ground separation) and stopped in that state.

Next, the hydraulic cylinder 6 is moved forward to extend the rod. As a result, the float 5 is lifted upward with the connection portion 4 as a center, and the stern-side spat 2 is tilted forward with the lower end piercing the seabed, thereby advancing the barge 1 by a predetermined distance (FIG. 6).

The barge 1 moves by the stroke of the hydraulic cylinder 6 in proportion to the length of the spat 2 to the seabed. If the movement of the barge 1 is within the range of the stroke of the hydraulic cylinder 6, Any distance can be selected.

The spat 2 is tilted back and forth by swinging the float 5 as described above to move the barge 1 to a predetermined position. When the barge 1 reaches the predetermined position, the two bow-side bows are moved. The spats 21 and 22 are again landed on the seabed, and the barge 1 is fixed at that position. Thereafter, the above-mentioned spat 2 pierced into the seabed is lifted and separated from the seabed, and simultaneously the cylinder 6 is operated in reverse. To return the spat 2 to the vertical state as shown in FIG.
Landed on the seabed again, and three spats 2,21,2
2, the barge 1 is positioned and fixed.

The barge apparatus shown in FIG. 2 is provided with two tiltable spats on the bow side, and can move more reliably than the barge shown in FIG.

[0026]

Since the present invention is configured as described above, it has the following advantages. 1) The barge can be moved in a so-called “wireless” without using a winch as in the related art. 2) The amount of movement of the barge can be arbitrarily determined as long as it is within the stroke of the cylinder. 3) The barge can be moved safely by one-man control in a shorter time than the conventional winch maneuvering method. 4) The source of hydraulic pressure supplied to the hydraulic cylinder can be shared with the hydraulic source of the spat elevating device, so there is no need to provide a new pump unit. 5) Since the barge is moved by the tilting operation of the spat landing on the seabed, it can be used as the original positioning spat like other spats after moving.
