船の建造において、船底壁の補強リブ或いは、該船底壁に沿わせて内壁を構築するために、船底壁板に、断面T字状の長尺部材を壁板の面に沿わせて溶接することが行われている。
長尺部材を壁板に溶接した後は、溶接部のスケールを除去してから塗装しなければならない。
従来は、溶接部のスケールの除去は、グラインダーやワイヤーブラシによって、作業者が手作業で行っており、作業能率が悪く、且つ作業者に重労働に強いることになる。しかも、長尺部材の全長に亘る溶接部のスケールを確実に除去することは難しい。
本発明は、上記問題を解決できる研掃方法、及び研掃装置を明らかにするものである。
【0003】
【課題を解決する手段】

台車(2)を一定速度で走行させることにより、研掃斑は生じない。
従って、基板(70)上に長尺部材(71)が、その全長に亘って溶接されている場合、溶接部の全長を能率的、且つ均一に研掃して溶接スケールの除去を確実に行なうことができる。
台車(2)の左右に研掃材噴射ノズル(5)(5)を配備することにより、長尺部材(71)の縦帯板(73)を挟んで左右両側に露出している溶接部を同時に研掃できる。

【0013】
上記ブラケット(65)に研掃材噴射ノズル(5)が取り付けられる。
図6に示す如く、研掃材噴射ノズル(5)は、外ノズル(51)と内ノズル(52)の二重構造となっており、外ノズル(51)を貫通して内ノズル(52)の基端が開口しており、該開口に研掃材噴射ホース(53)が接続される。

【0016】
研掃材噴射ホース(53)内を圧力空気に乗って流れる研掃材が、研掃材噴射ノズル(5)の内ノズル(52)から溶接部(73)に噴射される。これによって溶接部(75)のスケールは剥離除去され、研掃材と一緒に回収通路(54)、回収ホース(55)を経て研掃材回収装置に回収される。研掃材噴射ノズル(5)先端に環状に密に植設したブラシ毛(56)が研掃材が外部に漏れることを効果的に防止できる。
【0017】
従来の様な、グラインダーやワイヤーブラシを用いての手作業による溶接スケールの除去に比べて、作業者の負担は飛躍的に軽減される。
然も、研掃による溶接スケールの除去であるから、研掃装置(1)の走行を一定速度に保てば、溶接部の全長に亘って斑なく溶接スケールの除去を行なうことができる。
【0018】
実施例の研掃装置(1)は、構造体(7)の2つのコーナ部(74)(74)に対向可能に、2つの研掃材噴射ノズル(5)(5)を具えているため、両コーナ部(74)(74)の溶接部(75)(75)を同時に研掃できる。
図1、図3に示す如く、T字状長尺部材(71)の横帯板(72)と縦帯板(73)とによって構成されるコーナ部(74a)(74a)を研掃する必要がある場合、研掃材噴射ノズル(5)(5)が該コーナ部(74a)(74a)に対向する様に、ノズル支持体(6)のネジ調節箇所を調節し、ブラシ毛(56)をコーナ部(74a)に押圧して弾性変形させれば可い。
【0019】
尚、台車(2)の車軸(32)(33)に対して、駆動ローラ(3)と案内ローラ(30)を軸方向にスライド可能且つ位置決め可能に配備し、又、補助ローラ(4)取付け用の取付部材(41)を台車(2)上の丸軸(41b)に対して軸方向にスライド可能且つ位置決め可能に配備することにより、長尺部材(71)の横帯板(72)の幅、即ち、レール(76)の幅が異なる場合でも対応できる。
軸(32)(33)(41b)を、入れ子式に伸縮可能に構成しても、幅の異なるレールに汎用性を持たすことができる。
【0020】
実施例は、基板(70)に断面T状の長尺部材(71)を溶接した場合であるが、基板(70)を、長尺部材(71)を構成する横帯板(72)と同様の帯板とすることで、断面H型の構造体に対する、溶接部のスケール除去に実施できるのは勿論である。
更に、この断面H型の長尺の構造体を、船底壁等相手部材に面に沿って溶接する場合において、溶接部のスケールの除去に本発明の研掃装置を使用できるのは勿論である。
【0021】
更に本発明では、構造体(7)のコーナ部に限らず、研掃材噴射ノズル(5)を構造体(7)の研掃したい部位に向けることによって、構造体(7)のフラット壁面を長尺部材(71)の長手方向に研掃することもできる。この場合、研掃材噴射ノズル(5)のブラシ毛(56)を90°にカットする必要はない。研掃装置(1)の前進走行と後退走行の切替え毎に、研掃材噴射ノズル(5)の高さ位置をずらすことにより、壁面を広幅に研掃できる。
【0022】
上記実施例の説明は、本発明を説明するためのものであって、特許請求の範囲に記載の発明を限定し、或は範囲を減縮する様に解すべきではない。又、本発明の各部構成は上記実施例に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能であることは勿論である。

Since the rail (76) is sandwiched between the front and rear of the carriage (2) by fitting the longitudinal edge of the carriage (2), the carriage (2) does not come off from the rail (76), but follows the rail (76). And can run smoothly.
[0016]
The abrasive material flowing on the compressed air injection hose (53) on the pressurized air is injected from the inner nozzle (52) of the abrasive injection nozzle (5) to the welded portion (73). As a result, the scale at the welded portion (75) is peeled and removed, and is recovered together with the abrasive material through the recovery passage (54) and the recovery hose (55) into the abrasive material recovery device. The brush bristles (56) densely implanted annularly at the tip of the cleaning material spray nozzle (5) can effectively prevent the cleaning material from leaking to the outside.
[0017]
The burden on the operator is greatly reduced as compared with the conventional manual removal of the welding scale using a grinder or a wire brush.
Of course, since the welding scale is removed by polishing, if the traveling of the polishing apparatus (1) is maintained at a constant speed, the welding scale can be removed without unevenness over the entire length of the welded portion.
[0018]
The blasting device (1) of the embodiment is provided with two blasting material injection nozzles (5) (5) so as to be able to face the two corner portions (74) (74) of the structure (7). In addition, the welds (75) and (75) of the two corners (74) and (74) can be ground simultaneously.
As shown in FIG. 1 and FIG. 3, it is necessary to clean the corner portions (74a) (74a) composed of the horizontal band plate (72) and the vertical band plate (73) of the T-shaped long member (71). If there is, the screw adjustment portion of the nozzle support (6) is adjusted so that the abrasive injection nozzles (5) (5) face the corners (74a) (74a), and the brush bristles (56) May be pressed against the corner portion (74a) to be elastically deformed.
[0019]
The drive roller (3) and the guide roller (30) are provided so as to be slidable and positionable in the axial direction with respect to the axles (32) and (33) of the bogie (2), and the auxiliary roller (4) is attached. Mounting member (41) is provided so as to be axially slidable and positionable with respect to the round shaft (41b) on the trolley (2), so that the width of the horizontal band (72) of the long member (71) can be reduced. That is, it is possible to cope with the case where the width of the rail (76) is different.
Even if the shafts (32), (33), and (41b) are configured to be telescopically extendable, the rails having different widths can have versatility.
[0020]
In the embodiment, a long member (71) having a T-shaped cross section is welded to the substrate (70), and the substrate (70) is formed in the same manner as the horizontal band plate (72) constituting the long member (71). It is a matter of course that the scale plate of the H-shaped section can be used to remove the scale of the welded portion.
Further, when the long structure having the H-shaped cross section is welded to a mating member such as a ship bottom wall along a surface, it is a matter of course that the polishing apparatus of the present invention can be used for removing the scale of the welded portion. .
[0021]
Further, in the present invention, the flat wall surface of the structural body (7) is not limited to the corner portion of the structural body (7), but is directed to the portion of the structural body (7) to be cleaned, by directing the abrasive injection nozzle (5). The long member (71) can also be polished in the longitudinal direction. In this case, it is not necessary to cut the brush bristles (56) of the cleaning material injection nozzle (5) at 90 °. The wall surface can be broadened by shifting the height position of the abrasive injection nozzle (5) every time the polishing apparatus (1) switches between forward traveling and backward traveling.
[0022]
The description of the above embodiments is intended to explain the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims.
