Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a dredger equipped with an upper revolving body such as a boxboat or a club boat, and more specifically to a dredger equipped with a drainage structure.

``Prior Art'' This type of dredger generally has an upper revolving body 1 such as a backhoe attached to a barge 2 via a revolving support device 3 so as to be rotatable, as shown in FIG.

In such a dredger, it is normal to use an upper revolving body 1 designed for land use.

In the upper revolving structure 1 of land specifications, the upper revolving structure 1 and the lower traveling body are connected by a turning wheel, and a center joint is attached to supply hydraulic pressure to the lower traveling body. When this upper revolving body 1 is mounted on a barge 2 for dredging specifications,
The lower running body is no longer needed and the center joint can be removed. In a land machine, water such as rainwater that accumulates in the upper revolving body 1 exits the machine through the mounting hole of the center joint.

On the other hand, even in the dredging specification, water entering the upper revolving structure 1 falls to the lower part through the hole from which the center joint has been removed. However, in a dredger, the water that falls from the upper revolving body 1 cannot be collected at the bottom of the barge 2, and the water that has accumulated on the bottom of the ship must be drained out of the ship, or the water must be prevented from entering the bottom of the ship. There is a need to.

Therefore, conventionally, a drainage pump is installed on the bottom of the barge 2, and the water accumulated at the bottom of the boat is pumped up and drained out of the boat. Further, as shown in FIG. 3, a blind plate 11 is fixed to the mounting hole of the center joint formed after removing the center joint of the swing support device 3 to block the mounting hole. A drain port 12 is provided, and one end of a drain pipe 13 is connected to the drain port 12. An opening/closing valve 8 is provided at the other end of the drain pipe 13, and the other end faces a container 9 installed on the bottom of the ship. Receive water in container 9,
Whenever it accumulates in the container 9, it is discharged overboard.

In addition, in the figure, 6 is a mito, and 7 is a turning wheel grease chamber.

``Problems to be Solved by the Invention'' However, the former method requires a drainage pump and is therefore expensive. In addition, the latter has a problem in that the cost for modifying the barge 2 increases because the drain pipe 13 is disposed inside the ship, that is, between the swing support device on the deck 5 and the bottom of the ship. Furthermore, in the former and latter, water is once received at the bottom of the ship or in the container 9, so it is necessary to drain water periodically, and even when the ship is at rest, if it rains, there is a problem that drainage work must be carried out. There is.

The present invention aims to provide a dredger that solves the above-mentioned problems.

"Means for solving the problem" The present invention fixes a blind plate to the center joint mounting hole formed after removing the center joint of the swing support device, and provides a water drain port in the blind plate. It is characterized in that a drain port is provided in the cylindrical body of the swing support device, and a drain pipe is interposed between the drain port and the water drain port.

``Operation'' Water that falls from the upper revolving structure is prevented from entering the bottom of the ship by a lid installed within the revolving support device. Further, the water accumulated in this swing support device is drained out of the ship through a drainage pipe.

"Embodiment" Hereinafter, an embodiment of a dredger equipped with an upper rotating body according to the present invention will be described with reference to FIG. 1.

FIG. 1 is a sectional view of the main parts of an embodiment of a dredger equipped with an upper revolving body according to the present invention.

In the figure, the same reference numerals as in FIGS. 2 and 3 indicate the same parts.

Therefore, the dredger of the present invention in this embodiment is provided with a drain port 10 in the round body 4 of the swing support device 3, and a hose serving as a drain pipe between the drain port 10 and the water drain 12 of the blind plate 11. 14 is inserted.

Since the dredger of the present invention in this embodiment has the above-described configuration, the water falling from the upper revolving structure 1 is collected by the blind plate 1 installed in the revolving support device 3.
1 prevents entry to the bottom of the ship. Further, the water accumulated in the swing support device 3 is constantly drained out of the boat through the hose 14. At this time, the water is drained constantly, so there is no need to carry out drainage work even when the vessel is in use. Moreover, since drainage can be performed without using a drainage pump, a drainage pump is not necessary.

Furthermore, since the hose 14 is simply interposed between the drain port 10 of the round body of the swing support device 3 and the water drain port 12 of the blind plate 11, there is no need to modify the barge 2.

"Effects of the Invention" As is clear from the above embodiments, the dredger equipped with the upper revolving body of the present invention can achieve the following effects.

(b) Since drainage can be carried out at all times, there is no need to carry out drainage work even if rainwater enters the vessel when the vessel is at rest.

(b) Since the drainage is natural drainage, a drainage pump is not required.

(c) Since the drainage pipe is installed in the swing support device, there is no need to modify the barge and there is no need for modification costs.
