Description

本発明は溶接鋼管研磨技術分野を取り上げて、具体的にはストレートシーム鋼管内壁のシームに対する研磨装置である。 The present invention takes up the field of welding steel pipe polishing technology, and specifically, is a polishing device for a seam of a straight seam steel pipe inner wall.

溶接鋼管はストレートシーム鋼管とスパイラルシーム鋼管に分けられている。ストレートシーム鋼管の継目（シーム）の形状がパイプの長さ方向に平行で真っすぐであり、スパイラルシーム鋼管にはらせん状の継目がある。また管径の大きい鋼管が主にスパイラルシーム鋼管を採用し、管径の小さい鋼管がストレートシーム鋼管を採用する。シームの要件を満たすには鋼管のシームに研磨を行う必要があり、ストレートシーム鋼管の管径が小さいため、専用の研磨装置により研磨を行う必要がある。従来のストレートシーム鋼管内壁のシームに対する研磨装置は同じ直径を有する鋼管しか研磨できなく、適応性が悪い。上記の問題を解決するために、ストレートシーム鋼管内壁のシームに対する研磨装置を考案した。 Welded steel pipes are divided into straight seam steel pipes and spiral seam steel pipes. The shape of the seam of the straight seam steel pipe is parallel to the length direction of the pipe and is straight, and the spiral seam steel pipe has a spiral seam. Spiral seam steel pipes are mainly used for steel pipes with a large pipe diameter, and straight seam steel pipes are used for steel pipes with a small pipe diameter. In order to meet the seam requirements, it is necessary to polish the seam of the steel pipe, and since the diameter of the straight seam steel pipe is small, it is necessary to polish it with a dedicated polishing device. The conventional polishing device for the seam of the inner wall of the straight seam steel pipe can only polish the steel pipe having the same diameter, and the adaptability is poor. In order to solve the above problem, a polishing device for the seam of the inner wall of the straight seam steel pipe was devised.

作動時、作業員が手動で円柱形車体１１をストレートシーム鋼管の内部に置き、そして電磁石３１が通電により円盤３５を吸引し、円盤３５がスプラインスリーブ３９、固定筒３０及びボルト３７を後方へ移動させることで、回転盤３６の回転に対する制限を解除し、捻りばね２７により回転盤３６が回転し、さらにコンロッド１７により伸縮棒１３を回転軸１８から離れるように移動させ、車輪１４がストレートシーム鋼管の内壁と当接し、ここで円柱形車体１１が自動的にストレートシーム鋼管の内径に対応することを可能にし、
もし回転盤３６が回転量が小さく、即ち始動ブロック２０が右方へ回転しても位置スイッチ６６をオンにすることはなく、リニアモーター４８が作動しなく、
もし回転盤３６が回転し、そして始動ブロック２０が右方へ回転して左上方の位置スイッチ６６をオンにしたら、サブ電動シリンダー５０がサブ伸縮棒５１を収縮させることで、サブ伸縮棒５１がサブ砥石車５２の上側に位置し、そしてリニアモーター４８がサブ電動シリンダー５０及びサブ伸縮棒５１を右方へ二つのサブ砥石車５２の間に位置させ、回転盤３６の回転により始動ブロック２０が右方へ回転して左下方の位置スイッチ６６をオンにしたら、サブ電動シリンダー５０がサブ伸縮棒５１を収縮させることで、サブ伸縮棒５１をサブ砥石車５２の上側に位置させ、そしてリニアモーター４８がサブ電動シリンダー５０及びサブ伸縮棒５１を右方へ右方のサブ砥石車５２の右側に移動させ、
そしてサブ電動シリンダー５０がサブ伸縮棒５１を降下させることで、サブ伸縮棒５１をサブ砥石車５２と当接させ、電動シリンダー２５が作動して操作棒２６を右方へ移動させ、操作棒２６が妨害板５７、伸縮ばね５８及びスライドリング６２を右方へ移動させることで、挟持棒５９が貫通溝５６の右内壁と当接し、挟持棒５９とスライドリング６２が引き続き右方へ移動できなくなり、そして操作棒２６が妨害板５７を右方へ移動させ、操作棒２６の右方への移動によりサブコンロッド６０が回転し、挟持棒５９を操作棒２６に接近するように移動させ、挟持棒５９が内穴２４に移動し、リニアモーター４８がサブ電動シリンダー５０、サブ伸縮棒５１及びサブ砥石車５２を左方へ砥石車軸２３に移動させ、またサブ砥石車５２が砥石車２２及びサブ砥石車５２と圧着し、電動シリンダー２５が操作棒２６及び妨害板５７を左方へ移動させ、操作棒２６の左方への移動によりサブコンロッド６０が逆回転し、挟持棒５９を操作棒２６から離れるように移動させて復帰させ、操作棒２６が挟持棒５９を左方へ移動させることで、挟持棒５９をサブ砥石車５２の右面と当接させ、サブ砥石車５２と砥石車２２とを挟持固定し、サブ砥石車５２と砥石車２２とによって研磨輪を構成し、
即ちストレートシーム鋼管の内径に応じて研磨輪の幅を調整でき、また研磨輪の幅はストレートシーム鋼管の内径の増加につれ増加するため、作業員が手動で円柱形車体１１を回転させることで研磨輪をストレートシーム鋼管の内壁と合わせることに便利を与え、ストレートシーム鋼管の内径と研磨輪の幅に差があることにより、シームを研磨輪と合わせられない問題を回避でき、
続いて電動昇降シリンダー２８が昇降棒４４を降下させ、昇降棒４４が復帰ばね６４によりモータ台座４１を降下させることで、研磨輪をストレートシーム鋼管内壁のシームと当接させ、昇降棒４４が引き続き降下し、接点ブロック６３を介して位置制限スイッチ６５をオンにし、そして電動昇降シリンダー２８が作動を止め、昇降棒４４が降下を止め、復帰ばね６４の圧縮量を設定量に保ち、即ち研磨輪がシームに対する研磨圧力を設定値に保ち、研磨効果を保証し、そして研磨モータ４２が砥石車軸２３、砥石車２２、電動シリンダー２５、挟持棒５９及びサブ砥石車５２を回転させ、シームに研磨を行い、またモータ１６が作動し、モータ軸１５及び車輪１４を回転させ、車輪１４が鋼管の内壁に沿って移動し、ここでストレートシーム鋼管内壁のシームを自動的に研磨することを可能にし、
研磨が終わったら、電磁石３１が停電し、圧縮ばね３４により円盤３５が左方へ移動して復帰し、スプラインスリーブ３９をスプライン空間４０とスプラインを介して連結し、この時に位置制限穴１９が回転軸１８の上側に位置していないため、ボルト３７が回転盤３６の右面と当接し、そして収容モータ３３が作動し、伝動軸３２を回転させ、伝動軸３２がキーによる連結を介してスプラインスリーブ３９を回転させ、スプラインスリーブ３９とスプライン空間４０とのスプラインによる連結を介して回転盤３６を回転させ、回転盤３６が逆回転して復帰し、さらにコンロッド１７により伸縮棒１３を回転軸１８に接近するように移動して復帰させ、車輪１４を自動的に収容することを可能にし、位置制限穴１９を回転軸１８に回転させ、ばね３８によりボルト３７が前方へ移動して再び位置制限穴１９に延在し、回転盤３６が再びロックされる。 During operation, the worker manually places the cylindrical body 11 inside the straight seam steel pipe, and the electromagnet 31 attracts the disk 35 by energizing, and the disk 35 moves the spline sleeve 39, the fixing cylinder 30 and the bolt 37 backward. By doing so, the restriction on the rotation of the turntable 36 is released, the turntable 36 is rotated by the torsion spring 27, and the telescopic rod 13 is further moved away from the rotating shaft 18 by the conrod 17, and the wheel 14 is a straight seam steel pipe. In contact with the inner wall of the, where the cylindrical body 11 can automatically correspond to the inner diameter of the straight seam steel pipe,
If the turntable 36 has a small amount of rotation, that is, even if the starting block 20 rotates to the right, the position switch 66 will not be turned on and the linear motor 48 will not operate.
If the turntable 36 rotates and the start block 20 rotates to the right and the position switch 66 on the upper left is turned on, the sub electric cylinder 50 contracts the sub telescopic rod 51 to cause the sub telescopic rod 51 to rotate. Located above the sub grindstone 52, and the linear motor 48 positions the sub electric cylinder 50 and the sub telescopic rod 51 to the right between the two sub grindstones 52, and the rotation of the turntable 36 causes the starting block 20 to move. After rotating to the right and turning on the lower left position switch 66, the sub electric cylinder 50 contracts the sub telescopic rod 51 to position the sub telescopic rod 51 above the sub grindstone 52, and the linear motor. 48 moves the sub electric cylinder 50 and the sub telescopic rod 51 to the right and to the right of the sub grindstone 52 on the right.
Then, the sub electric cylinder 50 lowers the sub telescopic rod 51 to bring the sub telescopic rod 51 into contact with the sub grindstone 52, the electric cylinder 25 operates to move the operation rod 26 to the right, and the operation rod 26 Moves the obstruction plate 57, the telescopic spring 58, and the slide ring 62 to the right, so that the holding rod 59 comes into contact with the right inner wall of the through groove 56, and the holding rod 59 and the slide ring 62 cannot continue to move to the right. Then, the operating rod 26 moves the obstruction plate 57 to the right, and the movement of the operating rod 26 to the right causes the sub-con rod 60 to rotate, and the holding rod 59 is moved so as to approach the operating rod 26. 59 moves to the inner hole 24, the linear motor 48 moves the sub electric cylinder 50, the sub telescopic rod 51 and the sub grindstone 52 to the left to the grindstone shaft 23, and the sub grindstone 52 moves the grindstone 22 and the sub grindstone. When crimped with the car 52, the electric cylinder 25 moves the operation rod 26 and the obstruction plate 57 to the left, and the movement of the operation rod 26 to the left causes the subcon rod 60 to rotate in the reverse direction, and the holding rod 59 is moved from the operation rod 26. The operation rod 26 moves the holding rod 59 to the left so that the holding rod 59 is brought into contact with the right surface of the sub grindstone 52, and the sub grindstone 52 and the grindstone 22 are brought into contact with each other. It is sandwiched and fixed, and the polishing wheel is composed of the sub grindstone 52 and the grindstone 22.
That is, the width of the polishing wheel can be adjusted according to the inner diameter of the straight seam steel pipe, and the width of the polishing wheel increases as the inner diameter of the straight seam steel pipe increases. It is convenient to match the ring with the inner wall of the straight seam steel pipe, and the difference between the inner diameter of the straight seam steel pipe and the width of the polishing ring avoids the problem that the seam cannot be matched with the polishing ring.
Subsequently, the electric elevating cylinder 28 lowers the elevating rod 44, and the elevating rod 44 lowers the motor pedestal 41 by the return spring 64, so that the polishing wheel is brought into contact with the seam on the inner wall of the straight seam steel pipe, and the elevating rod 44 continues. It descends, turns on the position limiting switch 65 via the contact block 63, and the electric elevating cylinder 28 stops working, the elevating rod 44 stops descent, keeping the amount of compression of the return spring 64 at the set amount, i.e. the polishing wheel. Keeps the polishing pressure on the seam at the set value and guarantees the polishing effect, and the polishing motor 42 rotates the grindstone shaft 23, the grindstone 22, the electric cylinder 25, the holding rod 59 and the sub grindstone 52 to polish the seam. And also the motor 16 is activated to rotate the motor shaft 15 and the wheels 14, allowing the wheels 14 to move along the inner wall of the steel pipe, where the seams on the inner wall of the straight seam steel pipe are automatically polished.
When the polishing is completed, the electromagnet 31 loses power, the disk 35 moves to the left by the compression spring 34 and returns, and the spline sleeve 39 is connected to the spline space 40 via the spline, and at this time, the position limiting hole 19 rotates. Since it is not located above the shaft 18, the bolt 37 abuts on the right side of the turntable 36, and the accommodating motor 33 operates to rotate the transmission shaft 32, which sprine sleeve through key connection. The 39 is rotated, the turntable 36 is rotated through the spline connection between the spline sleeve 39 and the spline space 40, the turntable 36 is rotated in the reverse direction and returned, and the telescopic rod 13 is made into the rotating shaft 18 by the conrod 17. It moves closer and returns, allowing the wheels 14 to be automatically accommodated, rotating the position limiting hole 19 around the rotating shaft 18, and the spring 38 moving the bolt 37 forward and again the position limiting hole. It extends to 19 and the turntable 36 is locked again.
