Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device suitable for cleaning upright quay walls, particularly quay walls whose surfaces are protected by steel sheet piles.

Shells such as barnacles are attached to this type of upright quay, but the conventional method for removing these types of shells is to scrape off the attached shells by operating from the ship. There is. However, this method has problems in that the work boat is constantly rocking on the water, which makes the work difficult and dangerous, and scraping is uncertain, and it requires a lot of time and money. The dot was hot.

The purpose of this proposal is to provide a quay cleaning device that can efficiently remove shells adhering to quay walls using simple means. A nozzle holder equipped with an injection nozzle capable of injecting high-pressure water toward the quay surface is provided on this column so that it can move up and down, and the high-pressure water injection nozzle is moved up and down along the column. The feature is that the shells can be scraped off using the pressure of high-pressure jet water.

Next, the cleaning device according to the present invention will be described based on the illustrated embodiment. FIG. 1 is a side view showing the overall structure. As can be seen from the figure, this cleaning device consists of a pillar 1 that is erected in the sea in front of a quay wall A formed with steel sheet piles, and a high-pressure support that is slidably installed along this pillar 1. Water injection nozzle 2
and the support 1 installed at the upper end of the support 1 is connected to the quay wall A.
It consists of a support arm 3 for hanging on a quay wall while being isolated from the surface, and a guide ring 4 provided at the lower end of the support column 1.

The pillar 1 is made of, for example, H-shaped steel, and a hanging arm 5 is provided at the upper end to project horizontally toward the quay A when the pillar 1 is erected in the sea. A suspension ring 7 for suspending the entire support column 1 by a crane wire 6 is provided on the end of the arm 5 on the quay wall A side. Further, the lower end of the support column 1 has a pointed portion 8 that is pierced into the seabed B.

The high-pressure water injection nozzle 2 is provided on the front surface of a nozzle holder 9 attached to the column 1 so as to move up and down along the column 1 so as to face the quay wall A surface. This nozzle holder 9 is attached to the quay wall A side flange 1a of the column 1 as shown in FIGS. 2 and 3.
A rotor 10 such as a steel ball or roller is interposed between the flange 1a and the flange 1a in a case that holds the support 1, so that the rotor 10 can freely slide along the length of the support 1. It has a structure with a horizontal support N11 on the quay wall A side. A plurality of the high-pressure water injection nozzles 2 are provided on a horizontal pipe 12 at appropriate intervals, and are supported by a horizontal support 11 of a nozzle holder 9. Further, the nozzle holder 9 is suspended by an ascending cable 14 that is let out through a guide pulley 13 provided on the upper part of the support column 1, and the ascending/descending cable 14 is operated by a winch placed on the quay A. By doing so, it is made to move up and down along the support column 1. Further, a guide pulley 15 for a high-pressure water supply hose 16 is provided below the guide pulley 13, and the hose 16 from the high-pressure water supply pump on the quay A passes through the guide pulley 15 to the nozzle in the nozzle holder 9. It is connected to the pipe 12.

For example, as shown in FIG. 4, the support arm 3 for supporting the column 1 on the quay A
It is provided so as to protrude horizontally toward the upper surface of the board. This support arm 3 has a connecting end 3a that is slidable relative to the support column 1, for example.
The mounting height position with respect to the support column 1 can be adjusted to the water depth at the site by using means that allows the bolts 18 to be inserted in a detachable manner through a large number of through holes 17 opened in the connection end 3a and through the through holes in the connecting end 3a. It is now possible to change it freely depending on the situation. Further, a predetermined distance from the quay wall A surface of the support arm 3 is provided below the intermediate portion of the support arm 3 when the arm 3 is disposed on the quay wall A and the strut 1 is erected and supported on the shore. A protruding piece 19 is provided for isolation with an interval W.

The guide wheels 4 provided at the lower end of the support column 1 are attached to both ends of a horizontal arm 20, which is attached to a slightly upper portion of the lower end pointed portion 8 in a direction parallel to the surface of the quay wall A, so that the guide wheels 4 are located at the same height. At least two are provided. Further, these guide wheels 4 are provided vertically with respect to the horizontal arm 20 so as to rotate along the joints 21 of the steel sheet piles forming the quay wall A, and the guide wheels 4 are fitted into the joints 21. It is attached to the horizontal arm 20 so that the same distance W as the distance W separated by the support arm 3 at the upper end is provided between the support column 1 and the surface of the quay wall A in the assembled state. There is.

Further, the bearing piece 22 of the guide ring 4 is attached to the horizontal arm 2.
If the mutual spacing between the two guide wheels 4 differs depending on the type of sheet pile, each guide ring 4 is installed in the two joints 21 so as to be slidable on both ends of the sheet pile. It is provided so that the interval can be adjusted freely so that it can be fitted to the

The quay cleaning device according to the present invention has the above-mentioned structure, and when in use, the support pillars are
A suspension ring 7 on the suspension arm 5 at the upper end is suspended by a crane wire 6. As shown in the figure, when the suspension ring 7 at the rear end of the suspension arm 5 is suspended by the wire 6, the column 1 is suspended in an inclined manner such that the lower end approaches the quay wall A. The entire pillar 1 is suspended into the sea with the guide ring 4 of the section fitted into the joint 21 of the quay wall A.

In this way, when the lower end pointed part 8 of the support column 1 reaches the seabed and the pointed part 8 penetrates into the seabed, the support arm 3 on the upper part of the support support arm 3 whose attachment position with respect to the support support 1 has been determined in advance is placed on the quay wall A, and the strut 1 is erected with a predetermined distance W between it and the quay wall A by the projecting piece 19 of the support arm 3 and the guide ring 4 at the lower end of the strut. Note that the suspension arm 5 of the support column 1 remains suspended by the wire 6 even in this state.

In this state, the nozzle holder 9 is sequentially lowered from the upper part of the support 1 by the ascending rope 14, and high-pressure water supplied from the hose 16 is injected from the injection nozzle 2 onto the quay wall A surface where the shells are attached. Then, shells attached to the quay surface are peeled off using high-pressure water. After the shell removal work at a predetermined position is completed, the support column 1 is hoisted up by the crane wire 6, and is reinstalled at an adjacent position in the same manner as described above, and the removal work is successively carried out.

As described above, in the quay cleaning device according to the present invention, the jet nozzle 2 for peeling off shells attached to the quay A with high-pressure water is installed up and down along the support 1 erected in the sea in front of the quay A. Since the jet nozzle 2 is made to move, the high-pressure jet water from the jet nozzle 2 is applied to the quay wall A surface at a uniform speed and at equal intervals with respect to the quay wall A surface by the stable support 1 that is not affected by waves. This allows the shell removal work to be carried out reliably and efficiently. Of course, since all the work is done by workers on the ground, it has the advantage of being extremely safe.

Moreover, the support arm 3 at the upper end allows the support column 1 to be stably installed on the quay A, and the support arm 3 and the guide ring 4 at the lower end ensure that the support arm 3 is always placed on the quay A.
A predetermined distance W suitable for removing seashells can be maintained between the surface and the surface by jetting high-pressure water, and an appropriate seashell removal work can be performed. In addition, at least two guide wheels 4 are provided in parallel at the lower end of the column 1 so that they can fit into the joints 21 of the sheet piles, respectively, so that it is possible to prevent the column 1 from swinging laterally, and also to prevent the column from hanging and sinking. This has advantages such as being able to stably, smoothly, and quickly descend to the intended upright position at all times. It goes without saying that this device can also be applied to concrete quay walls other than sheet pile quay walls.
