Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cleaning device that is preferably used when cleaning an upright quay protected by a steel sheet pile or the like.

[Prior art and problems to be solved]

Conventionally, the upright quay whose surface is protected by sheet piles made of steel plates can be used to properly scrape off shells such as barnacles,
It is known that maintenance such as appropriate cleaning and coating is indispensable in order to prevent corrosion due to ebb and flow of tide as much as possible.

Therefore, the applicant arranges a high-pressure water jet nozzle so that it can move up and down along a pillar that is erected on the front surface of the wharf, and holds this pillar in parallel to the wharf with a support arm and at least a pair of guide wheels. We have developed a cleaning device that sprays high-pressure water onto the upright quay while moving the nozzle up and down to clean it (No. 62-38795).

In addition, in this type of cleaning device, a nozzle is placed inside the protective housing that moves up and down, and a connection part for the sewage recovery system is installed at the bottom of this protective housing to prevent contamination of the surrounding sea area by cleaning sewage. There are also proposals for such a purpose (JP-A-57-66397 and JP-A-61-159372).

However, in these devices, in order to efficiently perform the cleaning work on the quay wall, it is necessary to frequently move the protective fence horizontally, and it is troublesome to adjust each component accompanying this movement. There was a problem.

[Means for solving problems]

Therefore, in this invention, a guide frame that hangs forward of the shore wall is provided at one end of a supporting member provided with a weight for balancing, and a protective housing is movably provided along the guide frame. In addition, the high-pressure water injection nozzle in a quayside cleaning device in which a high-pressure water injection nozzle is further provided in the protective housing and a connection part for a wastewater drainage system is provided at the bottom is configured to be vertically and horizontally movable by a drive mechanism, while high-pressure water is used. The jet nozzle device is provided as a swivel nozzle in which a plurality of pairs of jet ports are provided in a swivel head mounted on the nozzle body and the jet ports are symmetrically and deviated by a predetermined angle for each pair with respect to the shore wall. The configuration makes it easier to handle and streamline the cleaning work on the quay wall.

[Action]

In the quay wall cleaning device according to the present invention, the opening of a protective housing arranged so as to be movable along the guide frame is brought into contact with the quay wall surface, and the vertical movement of the protective housing and the vertical and horizontal movement of the nozzle device cause high-pressure injection. The wall surface is washed with water, and the washed sewage containing the scraped shellfish and the like is removed from the connection part at the bottom of the enclosure through the sewage recovery system.

〔Example〕

Next, a preferred embodiment of the wall surface cleaning device according to the present invention will be described in detail below with reference to the accompanying drawings.

Is a pair of guide frames 16 disposed at one end of a support stage 14 having traveling wheels 12, 12 and a support stage for suspending and holding these guide frames 16, 16 at a position in front of the shore wall A. A balance weight 18 arranged on the other end of 14, a protective enclosure 22 that moves up and down along the guide frames 16 and 16 and has an opening 20 on the shore wall A side, and this protective enclosure. The body 22 is provided with a high-pressure water jet nozzle device 24 arranged so as to be vertically and horizontally movable, and a connecting portion 26 to a waste water recovery system provided at the bottom of the protective housing 22.

Each guide frame 16 is made of H-shaped steel or the like, and spacer members 28, 28 for holding these guide frames 16 at a predetermined distance from the shore wall surface A are respectively provided at the tip ends thereof. At the same time, a stopper member 30 is arranged on the bottom portion of the support stage 14 on the other end side.

On the other hand, the protective housing 22 is formed in a box shape having a substantially rectangular opening 20, and the guide rollers 3 arranged on both sides thereof.
2 and 32 are attached to the guide frames 16 and 16, and a screw motor 36 on the support stage 14 is rotated by a drive motor 34 formed of a weather-resistant material such as stainless steel to vertically move along the guide frame 16. It is configured to move.

Further, in the protective housing 22, a drive mechanism constituted by a combination of a seal type drive motor 38 and vertical and horizontal feed screw members 40.
42 is arranged, and the injection nozzle device 24 is operated by operating the drive mechanism 42.
Move vertically and horizontally.

In this case, an elastic seal member 43 made of, for example, a plate-shaped sponge is provided on the periphery of the opening 20 of the protective housing 22 to maintain the adhesion of the opening 20 to the shore wall A. Preferably (see FIG. 3).

Further, the high-pressure water injection nozzle device 24 is shown in FIGS.
As shown in the figure, a swivel head 46 is rotatably attached to the nozzle body 44, and the swivel head 46 is attached to the nozzle body 44.
, Two pairs of jet water channels 50, 50, 52, which are biased at an angle of 60 degrees and 90 degrees with respect to the axis X of the high-pressure water supply channel 48, respectively.
52 are made to face each other, and these jet water channels 5
A swirling jet nozzle device is used in which the high-pressure water jetting direction Y of each nozzle 54 mounted on the tip of 0, 50, 52, 52 is symmetrically offset with respect to the circumferential direction, for example, about 2 degrees. . In addition, each nozzle of the swirl injection nozzle device 24
In order to deviate the high-pressure water jetting direction Y of 54 symmetrically with respect to the circumferential direction, the mounting surface 56 of each nozzle 54 is divided into four like 56a, 56b, 56c and 56d, and the facing surface portions 56a and 56c are respectively divided. , 56b and 56d
Are symmetrically inclined by 2 degrees and these face parts 56
It is configured by making a, 56b, 56c, 56d and the ejection axis Z of the ejection nozzle 54 orthogonal to each other.

When using the quay wall cleaning apparatus 10 according to the present invention having such a structure, the spacer members 28, 28 at the tips of the guide frames 16, 16 disposed on the support stage 14 are brought into contact with the quay wall surface A and the stopper member 30 is provided. Is operated to utilize the balancing action of the weight 18, so that the guide frames 16, 16 are held substantially parallel to the shore wall surface A.

Next, the swirl jet nozzle device 24 in the protective housing 22 mounted on the guide frames 16 and 16 and the high pressure water supply system C of the high pressure water generator B are connected via the guide rollers 60 on the support stage 14, On the other hand, the connection portion 26 at the bottom of the protective housing 22 and the suction pipe E led out from the suction means D such as a vacuum wheel are connected via the guide roller 62 on the support stage 14.

Then, by operating the drive motor 34, the protective housing 22 is appropriately moved along the guide frames 16 and 16 so that the opening 20 faces the shore wall surface A and is brought into close contact therewith, and then the high-pressure water generator B.
Is operated to cause the swirl head 46 of the swirl jet nozzle device 24 to swivel to jet high-pressure water from each nozzle 54, and in synchronization with this, the swirl jet nozzle device 24 is appropriately moved in the vertical and horizontal directions of the housing 22 by the drive mechanism 42. Cleaning is performed by moving and removing the circles and dirt adhering to the rock wall surface A with high pressure water.

The sewage containing the shell pieces and the like generated by this washing operation is driven by the suction means D to be collected and removed from the bottom of the casing 22 through the suction pipe E to the outside.

When the cleaning of the portion surrounded by the guide frames 16 is completed, the spacer member 2 is operated by operating the stopper member 30.
The entire apparatus 10 may be moved laterally along the quay by the wheels 12 and 12 while the wheels 8 and 28 are slightly floated from the quay wall A, fixed again, and then the washing operation may be performed in the same manner as described above.
