Description

  The present invention relates to a hull outer plate coating apparatus in a ship construction ship dock or a repair ship dock (outdoor).

Conventionally, the construction work for construction ship docks or repair ship docks (outdoors) has a limited construction period, and a pole gun with a paint gun attached to the tip of a long and narrow bar is used to improve the painting efficiency of a wide range of hull skins. The spray painting work is carried out with large shaking up and down or left and right.
In this case, there are cases where paint mist is scattered due to the influence of weather conditions and causes damage to the surrounding area.
In order to prevent this, a hood is installed on a self-propelled work bench to prevent the paint mist from splashing outside the hood, and a fan is attached to the back of the hood to suck the generated paint mist.
However, when the pole gun is shaken greatly, the spraying direction of the paint gun (paint spray nozzle) is tilted with respect to the paint surface, so that the amount of paint reaching the paint surface decreases and also leaks to the outside of the hood and scatters. Paint mist increases.

The applicant of the present application provides a self-propelled machine (moving carriage) that runs along the wall of the dock as a hull skin coating device, and an arm (working table) that can turn on the self-propelled machine (moving carriage). Providing a support arm), a worktable that can be turned at the tip of the arm, a hood attached to this worktable, and controlling the hood and worktable to a predetermined distance with respect to the hull outer plate to perform painting (For example, Patent Document 1).
However, the one described in Patent Document 1 does not disclose anything about a paint gun or the like, and is unsuitable for spray painting work using a pole gun.

  In addition, the applicant of the present application provides a crank that is pivotally supported on the base end side by a first fulcrum provided on a long pedestal and rotates, and a fixed distance in the longitudinal direction from the first fulcrum in the pedestal. A link pivotally supported by a second fulcrum provided on the base end and slidably connected to an intermediate portion of the crankshaft on the distal end side of the crank, and swinging in response to rotation of the crank; The base end side is connected to a portion opposite to the second fulcrum with respect to the second fulcrum so as to be slidable by a required distance in the longitudinal direction on the base, and the middle is pin-connected to the distal end side of the link A slider crank that swings the distal end side to which the spray fixing device is attached while sliding the base end side according to the swing of the link is provided. The front end of the coating spray (paint injection nozzle) and the coating of the hull outer plate are provided. Keep the gap with the surface relatively constant And so, we proposed a coating apparatus (e.g., Patent Document 2.).

However, in the thing of patent document 2, although the clearance gap between the front-end | tip of a coating spray and the coating surface of a hull outer plate can be kept comparatively constant, when a coating spray is shaken largely, Since the spray direction of the paint spray is inclined, there is a problem that the amount of paint reaching the paint surface is reduced and the paint mist scattered is increased.
In addition, since the thing of patent document 2 is comparatively heavy, since it is comparatively heavy, it is unsuitable for mounting on the work bench | platform on the mobile trolley which self-propels on the bottom face of the dock mentioned later.

  In addition, as shown in FIG. 12, a telescopic telescopic ladder (work table support arm) is placed on a ladder car (moving carriage) 29 that self-propels on the bottom of the dock. ) 28 is provided so as to be able to turn, and a work rod with a handrail (work table) 20 is fixed to the upper end of the telescopic telescopic ladder 28, and is provided so as to be movable along the processing target surface (hull outer plate). A chamber 101 (hood) in which an opening is formed on a side surface facing the target surface, a seal member that seals a gap between the chamber and the processing target surface, and provided in the chamber, and the abrasive is porous. An injection means for injecting the blast medium contained in the elastic body to the surface to be processed through the opening of the chamber; and the blast medium connected to the chamber and injected to the surface to be processed. Blasting apparatus provided with a discharging means for discharging from the chamber by suction strike medium has been proposed (e.g., Patent Document 3).

  Devices such as a ladder car (moving carriage) 29, a telescopic telescopic ladder (workbench support arm) 28, a work rod with a handrail (workbench) 20 and a chamber 101 (hood) described in Patent Document 3 are used for painting work. However, there is no disclosure about a painting gun for painting work, which is unsuitable for spray painting work using a pole gun.

  Also, a first gripping portion is provided at the base end of the elongated rod body, and an injection nozzle is mounted at the distal end of the elongated rod body via a support shaft in a direction intersecting the elongated rod body, and the elongated rod body A long cylindrical second gripping portion is externally fitted on the peripheral surface of the second gripping portion so as to be rotatable within a certain angular range, and the second gripping portion and the injection nozzle are interlocked and connected to each other. When the gripping part is rotationally displaced, the ejection nozzle is oscillated and displaced in synchronism with this, so that the elongated rod body is greatly shaken during use so that the swing angle θ exceeds 30 degrees. There has been proposed a coating gun apparatus in which the spray nozzle can always be orthogonal to the surface to be coated even if tilted (for example, Patent Document 4).

However, although the one described in Patent Document 4 can swing and displace the injection nozzle so as to be orthogonal to the surface to be coated, the high-pressure coating liquid contains a passage formed in the elongated rod body, and It passes through a passage (rotating passage) formed in the support shaft that swings with respect to the elongated rod body, and is supplied to the injection nozzle. Part).
And at the beginning of use of the paint gun device, the possibility of paint leaking from the seal portion seems to be negligible, but the paint penetrates into the rotating support shaft and dries while it is repeatedly used and not used, There is a problem that it is highly likely that the spray nozzle is less likely to swing or that the amount of paint leaking from the gap (seal portion) of the support shaft is increased.

The swivel bearing member 6, the nozzle swivel shaft 7 and the swivel member 8 constitute a swivel nozzle connecting member 5.
The nozzle turning shaft 7 is fixed to the turning member 8 and freely rotates with the turning bearing member 6.

A passive arm 15 a for turning the paint spray nozzle 16 is attached to the nozzle turning shaft 7 (or the turning member 8).
When the passive arm 15 a is fixed to the turning member 8, the nozzle turning shaft 7 may freely turn with the turning bearing member 6 and / or the turning member 8.

A paint spray nozzle 16 that ejects paint is fixed to the tip of the swivel member 8 with a bolt (not shown) or the like.
A flexible paint supply hose 17 for supplying high-pressure paint is connected to the paint injection nozzle 16.
In this case, the paint spray nozzle 16 does not need to have a special structure, and a general-purpose nozzle can be used.

A fixed paint passage is formed inside the paint spray nozzle 16.
A paint supply hose 17 is connected to the entrance of the fixed paint passage.
The fixed paint passage means that there is no rotating portion as described in Patent Document 4 in the paint passage.
In this way, by adopting a fixed paint passage (no rotating part), it is possible to completely prevent leakage of high-pressure paint.

A base rotating shaft 11 parallel to the nozzle turning shaft 7 is rotatably attached to the operating rod 2 at a portion 20 to 30 cm ahead of the operating rod base 3 of the operating rod 2.
A disc-shaped drive arm 13a is attached to the center of the base rotating shaft 11, and a nozzle turning operation handle 12 is attached to the tip.

  In the example shown in FIG. 1, the switching valve 41 is of the switching electromagnetic valve type, and is operated via a control device (not shown) by pressing the valve operation foot switch 42, but is not limited thereto. Instead of this, a type in which the spool or the like of the switching valve 41 is extended and the extended portion is directly used as the valve operation foot switch 42 may be used.

(Modification of the first embodiment of the present invention)
Next, a modified example of the hull skin coating apparatus according to the first embodiment of the present invention will be described with reference to FIG.
The hull skin coating apparatus shown in FIG. 3 is different from that shown in FIGS. 1 and 2 by a nozzle turning operation handle 12, a base rotating shaft 11, a drive arm 13a, an interlocking member 14a, and a passive arm 15a. In place of the configured nozzle turning drive device 10a, the nozzle turning operation handle 12, the base rotating shaft 11, the rod-like drive arm 13b attached to the base rotating shaft 11, one rod-like interlocking member 14b, and the turning member 8 is provided with a nozzle turning drive device 10b constituted by a passive arm 15b attached to the motor.
The portable spray gun 1 has the same configuration as that shown in FIGS.
Moreover, the coating material supply unit 40a is provided like the thing shown in FIG. 1, FIG.

(Action / Effect)
Since the hull skin plate coating apparatus according to the first embodiment of the present invention including the portable spray gun 1, the nozzle turning drive devices 10a and 10b, and the paint supply unit 40a is configured as described above, The operation rod base 3 is placed on the body of the worker, the nozzle turning operation handle 12 and the fixed handle 4 (or both nozzle turning operation handles 12) are held with both hands, and the nozzle turning operation handle 12 is turned. The paint spray nozzle 16 can be freely swung through the nozzle swivel drive devices 10a and 10b, the nozzle swivel shaft 7 and the swivel member 8 by performing the dynamic operation.

Accordingly, the nozzle turning operation handle 12 is rotated according to the inclination of the operation rod 2 and the direction of the paint injection nozzle 16 can be sprayed perpendicularly to the paint surface of the hull outer plate, so that the paint surface is reached. Since the amount of paint to be applied increases, the coating efficiency (the amount of paint that contributes to the coating composition relative to the amount of paint supplied) is improved, and as a result, the amount of paint mist scattered is reduced.
Also, when performing painting work in the hood as described later on the hull skin coating device, the amount of suction coating mist decreases as the amount of coating mist scattering decreases, so the filter life is extended and the suction effect is increased. The time can be increased.

Moreover, in the thing of the conventional cited reference 4, it is the form which supplies a coating liquid to an injection nozzle via a support shaft from the elongate rod body base, and a coating material does not leak to the part of a support shaft. Thus, it is necessary to seal at high pressure through the packing.
On the other hand, in the hull skin coating apparatus according to the first embodiment of the present invention, the paint passage in the paint injection nozzle 16 is a fixed paint passage, and there is no rotating part and high-pressure seal part. The paint supply hose 17 is directly connected to the paint injection nozzle 16, and the paint does not leak from the paint injection nozzle 16.

Further, since the swivel nozzle connecting member 5 exposed to the paint mist is composed of only the swivel bearing member 6, the nozzle swivel shaft 7, and the swivel member 8, for example, the paint mist adheres to the swivel bearing and is dried. Can be easily disassembled and cleaned (maintenance).
Further, since the on / off operation of the paint supply is performed by the valve operation foot switch 42, both hands only need to operate the operation rod 2 and the nozzle turning operation handle 12.
In this way, it is possible to obtain a coating apparatus for a hull outer plate that has a paint injection nozzle 16 that is turnable at the tip of the operation rod 2 and that is lightweight and easy to maintain.

A closing plate 25 is attached to the mounting table 22 via a hinge 24 so as to be opened and closed.
The lower part of the operation rod mounting table 22 has a U-shaped groove so that the operation rod 2 can be slidably mounted.
Further, when the operating rod 2 is placed and slid, the operating rod 2 is covered by the closing plate 25 so that the operating rod 2 does not come off.

When performing the painting operation, the operation rod 2 of the portable spray gun 1 is placed in the U-shaped groove of the operation rod mounting table 22 and is stopped by the closing plate 25.
For example, when the portable spray gun 1 is raised upward, the operation rod 2 is tilted upward while protruding forward, and the paint turning nozzle 16 is turned downward by operating the nozzle turning operation handle 12.
In this way, the portable spray gun 1 is moved up and down while keeping the direction of the paint spray nozzle 16 of the portable spray gun 1 perpendicular to the painted surface of the hull outer plate and substantially equidistant from the painted surface. It becomes easy to perform painting work.
