Description

本発明は、補強帯用溶接台車に係り、特に、鋼製配水池の外周又は内周に巻回される、外方又は内方に突出した補強帯を溶接する際に用いるのに好適な補強帯用溶接台車に関する。 The present invention relates to a welding carriage for reinforcing strips, and is particularly suitable for use when welding a reinforcing strip protruding outward or inward, which is wound around the outer or inner circumference of a steel distribution reservoir. Welding trolley for strips.

鋼製の屋根板、底板、側板を有し、これらが溶接で接合された水道用の鋼製配水池が知られている（特許文献１～３参照）。 A steel distribution reservoir for water supply, which has a steel roof plate, a bottom plate, and a side plate and is joined by welding, is known (see Patent Documents 1 to 3).

その一つに、図１（正面図）及び図２（図１のII－IIに沿う水平断面図）に例示する如く、底板１１の上に、例えば３段の側板１２、１３、１４を積み重ね、その間を補強帯１５、１６で溶接して補強した配水池１０がある。図において、１８は柵である。 As one of them, as illustrated in FIGS. 1 (front view) and 2 (horizontal cross-sectional view taken along II-II of FIG. 1), for example, three-tiered side plates 12, 13 and 14 are stacked on the bottom plate 11. There is a distribution reservoir 10 reinforced by welding between the reinforcing bands 15 and 16. In the figure, 18 is a fence.

このような鋼製配水池１０において、従来、補強帯１５、１６は手作業で溶接していた。 In such a steel distribution reservoir 10, conventionally, the reinforcing bands 15 and 16 have been manually welded.

なお、配水池の溶接に関するものではないが、特許文献４には、圧力容器などの側面に突起したＴ字形フレーム材に沿って、目的箇所を連続的にすみ肉溶接する自走式無軌条溶接台車が記載されている。 Although it is not related to welding of the distribution reservoir, Patent Document 4 describes self-propelled railless welding in which the target portion is continuously fillet welded along the T-shaped frame material protruding from the side surface of the pressure vessel or the like. The dolly is listed.

又、特許文献５には、立板と細幅の下板のすみ肉溶接用無軌条自走台車が記載されている。 Further, Patent Document 5 describes a railless self-propelled bogie for fillet welding of a standing plate and a narrow lower plate.

又、特許文献６には、倣い面としてのすみ肉継手の縦板の垂直面に転接する案内ローラを、倣い面に押圧させて移動台車を案内させるようにした溶接線倣い装置が記載されている。 Further, Patent Document 6 describes a welding line copying device in which a guide roller that translocates to the vertical surface of a vertical plate of a fillet joint as a copying surface is pressed against the copying surface to guide a moving carriage. There is.

しかしながら、特許文献４に記載された技術では、対象構造物にＴ字形フレーム材のような部材があるか、又は設置しなければならない。又、溶接トーチのみを動かしており、溶接機などを台車に積載させて走行することを考慮していない。 However, in the technique described in Patent Document 4, the target structure must have or have a member such as a T-shaped frame material. In addition, only the welding torch is moved, and it is not considered to load a welding machine or the like on a trolley and run.

又、特許文献５に記載の技術は、無軌条で指定の線長を自走する機構として、立板に当接させた車輪をガイドとしているが、配水池補強部のように湾曲部の外側を走ることは考慮していない。又、立板の形状によっては台車の軌条に活用することができない。 Further, the technique described in Patent Document 5 uses a wheel in contact with a standing plate as a guide as a mechanism for self-propelling a specified line length with no rail, but is outside the curved portion like a distribution reservoir reinforcing portion. I do not consider running. Further, depending on the shape of the standing plate, it cannot be used for the rail of the bogie.

又、いずれの特許文献に記載の技術も、溶接機などを台車に積載させて走行することは考慮しておらず、特に、本発明の適用対象の一つである配水池のように、補強帯にある溶接線位置の溶接には適用することが困難である、などの問題点を有していた。 Further, neither of the techniques described in the patent documents considers that a welding machine or the like is loaded on a trolley and travels, and in particular, it is reinforced as in the distribution reservoir which is one of the application targets of the present invention. It had problems such as being difficult to apply to welding at the position of the welding line on the band.

以下、図面を参照して、本発明の実施の形態について詳細に説明する。なお、本発明は以下の実施形態及び実施例に記載した内容により限定されるものではない。又、以下に記載した実施形態及び実施例における構成要件には、当業者が容易に想定できるもの、実質的に同一のもの、いわゆる均等の範囲のものが含まれる。更に、以下に記載した実施形態及び実施例で開示した構成要素は適宜組み合わせてもよいし、適宜選択して用いてもよい。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the contents described in the following embodiments and examples. Further, the constituent requirements in the embodiments and examples described below include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those that are in a so-called equal range. Further, the components disclosed in the embodiments and examples described below may be appropriately combined or appropriately selected and used.

本発明の第１実施形態は、図３（図２の溶接台車部分を拡大して示す水平断面図）、図４（図３をIV方向から見た縦断面図）、図５（図４のＶ－Ｖ線に沿う横断面図）、図６（図４のVI－VI線に沿う横断面図）、図７（図４のVII－VII線に沿う横断面図）、図８（図２の溶接台車を後方から見た図）、及び、図９（図８のIX－IX線に沿う水平断面図）に示す如く、補強対象である配水池１０の外周に巻回される、外方に突出した補強帯１５を溶接するための補強帯用溶接台車２０であって、溶接機本体２２が搭載される荷台４０と、前記補強帯１５を挟んで該荷台４０を走行自在に支持するための荷台用車輪４２と、前記荷台４０の前方（図４の右方）に、フリーな支点４４により湾曲自在に配設される、支持車輪５２を備えた先台車５０と、該先台車５０に、ばね５５が配設された支点５４により配水池１０の方向（図３の上方）に付勢されて湾曲可能に支持された、走行用の主動力を与えるための前輪６０と、前記荷台４０の後方（図４の左方）に、フリーな支点４６により湾曲自在に配設される、支持車輪７２を備えた従台車７０と、該従台車７０に、ばね７５が配設された支点７４により配水池１０の方向（図３の上方）に付勢されて湾曲可能に支持された、溶接トーチ２４を誘導するための後輪８０と、を備えている。 The first embodiment of the present invention includes FIG. 3 (horizontal cross-sectional view showing an enlarged view of the welding carriage portion of FIG. 2), FIG. 4 (longitudinal cross-sectional view of FIG. 3 viewed from the IV direction), and FIG. 5 (FIG. 4). FIG. 6 (cross-sectional view taken along line VI-VI in FIG. 4), FIG. 7 (cross-sectional view taken along line VII-VII in FIG. 4), and FIG. 8 (FIG. 2). As shown in FIG. 9 (horizontal cross-sectional view along the IX-IX line in FIG. 8) and FIG. 9 (horizontal cross-sectional view taken along the IX-IX line in FIG. It is a welding carriage 20 for a reinforcing band for welding the reinforcing band 15 protruding from the above, and is for supporting the loading platform 40 on which the welding machine main body 22 is mounted and the loading platform 40 by sandwiching the reinforcing band 15. The front bogie 50 having the support wheels 52, which is arranged in front of the loading platform 40 (on the right side in FIG. 4) so as to be bendable by a free fulcrum 44, and the front bogie 50. , The front wheel 60 for providing the main power for traveling, which is urged in the direction of the distribution reservoir 10 (upper side in FIG. 3) by the fulcrum 54 in which the spring 55 is arranged and supported in a bendable manner, and the loading platform 40. Behind (on the left side of FIG. 4), a trolley 70 having support wheels 72, which is flexibly arranged by a free fulcrum 46, and a fulcrum 74 in which a spring 75 is arranged on the trolley 70. It comprises a rear wheel 80 for guiding the weld torch 24, which is urged and bendably supported in the direction of the distribution reservoir 10 (upper in FIG. 3).

前記荷台４０には、例えば中央に溶接機本体２２、後方（図４の左側）に溶接トーチ２４、溶接スプール２８が搭載される溶接スプール用掛台２６、前方（図４の右側）に制御盤３０、バッテリ３２を搭載することができる。図４において、２２Ａは、溶接用のシールドガスを溶接トーチ２４に供給するためのガス接続栓、２２Ｂはガスゲージ、２２Ｃはガス調整用ツマミ、２３はシールドガス用管である。 The loading platform 40 has, for example, a welding machine main body 22 in the center, a welding torch 24 in the rear (left side in FIG. 4), a welding spool rack 26 on which the welding spool 28 is mounted, and a control panel in the front (right side in FIG. 4). 30 and the battery 32 can be mounted. In FIG. 4, 22A is a gas connection plug for supplying a shield gas for welding to the welding torch 24, 22B is a gas gauge, 22C is a gas adjusting knob, and 23 is a shield gas pipe.

このように溶接に関わる主要な機材を荷台４０自体に設けているので、電源コード等による制限の影響を受けることがない。従って、補強帯１５にある溶接線を連続的に溶接することが可能となる。更に、立板に相当する側板でなく、補強帯１５をガイドとしているので、立板に相当する側板の形状による制限を受けない。 Since the main equipment related to welding is provided on the loading platform 40 itself in this way, it is not affected by the restrictions imposed by the power cord or the like. Therefore, the welding line on the reinforcing band 15 can be continuously welded. Further, since the reinforcing band 15 is used as a guide instead of the side plate corresponding to the standing plate, the shape of the side plate corresponding to the standing plate is not limited.

前記先台車５０は、その上下に一対の支持車輪５２が回転自在に設けられており、この支持車輪５２は、上下一対の先台車支持リンク５６両端の支点に配設されたコイルばね５７、５８（図４参照）により補強帯１５を上下から挟んで走行するように付勢されている。このように、先台車支持リンク５６の両端で回動自在とすることにより、補強帯１５の板厚の変化にも対応できる。なお、補強帯１５の板厚の変化が問題とならない場合には、先台車支持リンク５６の支持車輪５２側を固定してコイルばね５８を省略することもできる。 The front trolley 50 is provided with a pair of support wheels 52 rotatably above and below the front trolley 50, and the support wheels 52 are coil springs 57, 58 arranged at fulcrums at both ends of the pair of upper and lower front trolley support links 56. (See FIG. 4) is urged to run with the reinforcing band 15 sandwiched from above and below. In this way, by making the leading wheel support link 56 rotatable at both ends, it is possible to cope with a change in the plate thickness of the reinforcing band 15. If the change in the plate thickness of the reinforcing band 15 does not matter, the coil spring 58 may be omitted by fixing the support wheel 52 side of the leading wheel support link 56.

前記前輪６０を支持する前輪支持６２は、先台車５０の先端に設けられた支点５４に配設されたコイルばね５５により補強帯１５の外周端と当接する方向（図３の上方向）に付勢されている。 The front wheel support 62 that supports the front wheel 60 is attached in a direction (upward in FIG. 3) in contact with the outer peripheral end of the reinforcing band 15 by a coil spring 55 arranged at a fulcrum 54 provided at the tip of the front carriage 50. It is being pushed.

前記前輪６０は、例えば前輪支持６２に内蔵されたモータ（図示省略）によって回転駆動され、溶接台車２０全体を前方に引っ張るようにされている。補強帯１５の外周端に沿って、このように溶接台車２０の前方から引っ張るようにしたいわゆるフロントドライブ方式とすることによって、安定した走行が可能となる。従って、Ｔ字形フレーム材のような部材が無くても、前輪６０が主要動力として補強帯１５の端部を当接して前進することで曲線部、湾曲部の軌道修正を行うことができる。このように前輪６０が前進動力と軌道修正の機構を併せ持つことで、装置が軌道修正を無視して前進し落下するのを防ぐことができる。これに対して、荷台４０や従台車７０に走行用の主動力を与えた場合には、走行が不安定となって、溶接台車２０が補強帯１５から落ちてしまうことがある。なお、補助動力を前輪６０以外の車輪に追加することもできる。 The front wheel 60 is rotationally driven by, for example, a motor (not shown) built in the front wheel support 62, and pulls the entire welding carriage 20 forward. Stable running is possible by adopting the so-called front drive system in which the welding carriage 20 is pulled from the front along the outer peripheral edge of the reinforcing band 15. Therefore, even if there is no member such as a T-shaped frame material, the front wheel 60 can correct the trajectory of the curved portion and the curved portion by abutting and advancing the end portion of the reinforcing band 15 as the main power. By having the front wheel 60 have both the forward power and the trajectory correction mechanism in this way, it is possible to prevent the device from moving forward and falling while ignoring the track correction. On the other hand, when the main power for traveling is applied to the loading platform 40 and the trailing wheel 70, the traveling becomes unstable and the welding bogie 20 may fall from the reinforcing band 15. Auxiliary power can be added to wheels other than the front wheels 60.

前記従台車７０は、先台車５０と同様に、その上下に一対の支持車輪７２が回転自在に配設されており、この支持車輪７２は、上下一対の従台車支持リンク７６両端の支点に配設されたコイルばね７７、７８により補強帯１５を上下から挟んで走行するように付勢されている。このように、従台車支持リンク７６の両端で回動自在とすることにより、補強帯１５の板厚の変化にも対応できる。なお、補強帯１５の板厚の変化が問題とならない場合には、従台車支持リンク７６の支持車輪７２側を固定してコイルばね７８を省略することもできる。 Similar to the leading wheel 50, the trailing wheel 70 has a pair of support wheels 72 rotatably arranged above and below the trailing wheel 50, and the support wheels 72 are arranged at fulcrums at both ends of the pair of upper and lower trailing wheel support links 76. The coil springs 77 and 78 provided are urged to run while sandwiching the reinforcing band 15 from above and below. In this way, by making the trailing wheel support link 76 rotatable at both ends, it is possible to cope with a change in the plate thickness of the reinforcing band 15. If the change in the plate thickness of the reinforcing band 15 does not matter, the coil spring 78 may be omitted by fixing the support wheel 72 side of the trailing wheel support link 76.

前記後輪８０を支持する後輪支持８２も、前輪支持６２と同様に、従台車７０の後端に設けられた支点７４に配設されたコイルばね７５により、補強帯１５の外周端と当接する方向（図３の上方向）に付勢されている。 Like the front wheel support 62, the rear wheel support 82 that supports the rear wheel 80 also hits the outer peripheral end of the reinforcing band 15 by the coil spring 75 arranged at the fulcrum 74 provided at the rear end of the trailing wheel 70. It is urged in the tangential direction (upward in FIG. 3).

前記後輪８０の後輪支持８２には、図８に詳細に示す如く、溶接トーチ用支持８４が設けられ、溶接トーチ２４の先端にはトーチガイドローラ８５が設けられている。このトーチガイドローラ８５は、図示しない弱いスプリングにより、図９に示す如く、補強帯１５に向けて押し付けられ、これにより溶接トーチ２４を補強帯１５の板端部に沿って誘導するようにしている。なお、比較的小さい直径のトーチガイドローラ８５と後輪８０の中間で溶接トーチ２４を制御することで、ある程度の湾曲（Ｒ１０００程度）では溶接トーチ２４を特別に調整することなく、連続的な溶接が可能となる。 As shown in detail in FIG. 8, the rear wheel support 82 of the rear wheel 80 is provided with a support 84 for a welding torch, and a torch guide roller 85 is provided at the tip of the welding torch 24. The torch guide roller 85 is pressed toward the reinforcing band 15 by a weak spring (not shown), whereby the welding torch 24 is guided along the plate end portion of the reinforcing band 15. .. By controlling the welding torch 24 between the torch guide roller 85 and the rear wheel 80 having a relatively small diameter, continuous welding is performed without special adjustment of the welding torch 24 with a certain degree of curvature (about R1000). Is possible.

前記溶接トーチ用支持８４には調整機構８４Ａが設けられ、溶接トーチ２４の先端位置を、補強帯１５端部の段差及び板厚差に応じて上下左右に位置調整可能とされると共に、その上端には前記シールドガス用管２３が接続されている。 The welding torch support 84 is provided with an adjusting mechanism 84A so that the position of the tip of the welding torch 24 can be adjusted up, down, left and right according to the step at the end of the reinforcing band 15 and the difference in plate thickness, and the upper end thereof. The shield gas pipe 23 is connected to the shield gas pipe 23.

ここで、溶接トーチ２４の先端位置を補強帯１５と後輪８０の接点よりも後方（図９の下方）にずらしているのは、安定的なガイドを可能とするためである。 Here, the position of the tip of the welding torch 24 is shifted to the rear (lower side in FIG. 9) from the contact point between the reinforcing band 15 and the rear wheel 80 in order to enable stable guide.

次に、図１０を参照して施工手順を説明する。 Next, the construction procedure will be described with reference to FIG.

まずステップ１００で、対象となる溶接長（全周又は部分）を手溶接で仮付け（仮溶接と称する）する。 First, in step 100, the target welding length (entire circumference or portion) is temporarily attached (referred to as temporary welding) by manual welding.

次いでステップ１１０で、先台車５０と従台車７０を補強帯１５の所定の位置に設置する。 Then, in step 110, the leading bogie 50 and the trailing wheel 70 are installed at predetermined positions of the reinforcing band 15.

次いでステップ１２０で、図示しないクレーンを用いて、本装置の荷台４０を先台車５０と従台車７０の間に据付接続する。なお、設置後も、クレーン吊具は安全のために本設置が完了するまで取り外さない。 Then, in step 120, the loading platform 40 of the present device is installed and connected between the leading wheel 50 and the trailing wheel 70 by using a crane (not shown). Even after installation, the crane hanger will not be removed until the main installation is completed for safety.

次いでステップ１３０で、図示しないガスボンベ等により、ガス供給ラインを荷台４０のガス接続栓２２Ａに接続する。 Next, in step 130, the gas supply line is connected to the gas connection plug 22A of the loading platform 40 by a gas cylinder or the like (not shown).

次いでステップ１４０で、従台車７０の溶接トーチ２４の位置を調整する。 Then, in step 140, the position of the welding torch 24 of the trailing wheel 70 is adjusted.

次いでステップ１５０で、クレーンと荷台４０の接続を切り離し、本体を所定の位置に自立させる。 Then, in step 150, the connection between the crane and the loading platform 40 is disconnected, and the main body is made to stand on its own in a predetermined position.

次いでステップ１６０で、制御盤３０により溶接棒送り出し速度、シールドガス量、台車速度を調整する。 Next, in step 160, the welding rod delivery speed, the shield gas amount, and the carriage speed are adjusted by the control panel 30.

次いでステップ１７０で、溶接台車２０を走行させながら溶接を実施する。 Next, in step 170, welding is performed while the welding carriage 20 is running.

この際、図３の左側に示す如く、直線部を走行した溶接台車２０は、曲線部にかかると、図３の右側に示したように、補強帯１５の板端（外周端）に追従して安定走行する。 At this time, as shown on the left side of FIG. 3, when the welding carriage 20 traveling on the straight portion hits the curved portion, it follows the plate end (outer peripheral end) of the reinforcing band 15 as shown on the right side of FIG. Stable running.

溶接終了後、ステップ１８０で、溶接台車２０を前記と逆の手順で溶接対象の補強帯１５から取り外す。 After the welding is completed, in step 180, the welding carriage 20 is removed from the reinforcing band 15 to be welded in the reverse procedure of the above.

ここで、溶接台車２０を荷台４０、先台車５０及び従台車７０に分割しているのは、補強帯１５の曲線部（Ｒ＝１０００ｍｍ程度）に対応させるためである。同じ理由により先台車５０および従台車７０の回転領域を確保するために、荷台４０の平面形状は図３のような補強帯１５側の両端が切り欠かれた凸形状としている。 Here, the reason why the welding bogie 20 is divided into the loading platform 40, the leading bogie 50, and the trailing wheel 70 is to correspond to the curved portion (R = about 1000 mm) of the reinforcing band 15. For the same reason, in order to secure the rotation area of the leading wheel 50 and the trailing wheel 70, the planar shape of the loading platform 40 is a convex shape in which both ends on the reinforcing band 15 side are cut out as shown in FIG.

シールドガスは、本実施形態のようにシールドガス用管により外部から供給したり、ガスボンベを運ぶための追加の台車を設けて、溶接台車２０と共に補強帯１５の外周に沿って走行させたり、溶接台車２０に搭載したりすることが可能である。ガスボンベを溶接台車２０に搭載した場合は、外部からガスを補給することなく溶接を続けることができる。 The shield gas is supplied from the outside by a shield gas pipe as in the present embodiment, an additional carriage for carrying the gas cylinder is provided, and the shield gas is run along the outer periphery of the reinforcing band 15 together with the welding carriage 20 or welded. It can be mounted on the trolley 20. When the gas cylinder is mounted on the welding carriage 20, welding can be continued without supplying gas from the outside.

前記説明においては、溶接台車２０が一段目側板１２と二段目側板１３間の補強帯１５に配設されていたが、二段目側板１３と三段目側板１４間の補強帯１６の溶接にも同様に適用できる。 In the above description, the welding carriage 20 is arranged on the reinforcing band 15 between the first-stage side plate 12 and the second-stage side plate 13, but the welding of the reinforcing band 16 between the second-stage side plate 13 and the third-stage side plate 14 Can be applied to.

又、補強帯が配水池の内側に突出している場合には、溶接台車を配水池の内側に配設して、該補強帯を内側から溶接することも可能である。 Further, when the reinforcing band protrudes inside the distribution reservoir, it is also possible to dispose the welding carriage inside the distribution reservoir and weld the reinforcing band from the inside.

前記実施形態においては本発明が、配水池の補強帯の溶接に適用されていたが、本発明の適用対象はこれに限定されず、配水池以外の構造物の補強帯の溶接にも同様に適用できる。 In the above embodiment, the present invention has been applied to the welding of the reinforcing band of the distribution reservoir, but the application target of the present invention is not limited to this, and the same applies to the welding of the reinforcing band of the structure other than the distribution reservoir. Applicable.
