Description

本発明は、左右一対のレール上を左右の前輪及び左右の後輪の転動によって走行する鋳型搬送台車に関するものである。   The present invention relates to a mold transport carriage that travels on a pair of left and right rails by rolling left and right front wheels and left and right rear wheels.

特許文献１には、鋳型１を載置されて注湯ライン１２の左右一対のレール３２上を左右の前輪及び後輪の転動によって走行する鋳型搬送台車２０が記載されている。トラバーサ２９は鋳枠合せ位置２７と注湯ライン１２の入口位置３１との間で往復動される。トラバーサ２９の上面には、入口位置３１において、注湯ライン１２のレール３２と整列する一対のレール３０が設けられている。トラバーサ２９が入口位置３１に移動されると、鋳型搬送台車２０は、トラバーサ２９のレール３０から注湯ライン１２のレール３２に乗り移され、注湯ライン１２を走行する間に鋳型１に注湯される。     Patent Document 1 describes a mold transport carriage 20 on which a mold 1 is placed and travels on a pair of left and right rails 32 of a pouring line 12 by rolling of left and right front wheels and rear wheels. The traverser 29 is reciprocated between the casting frame alignment position 27 and the inlet position 31 of the pouring line 12. A pair of rails 30 aligned with the rails 32 of the pouring line 12 are provided on the upper surface of the traverser 29 at the entrance position 31. When the traverser 29 is moved to the inlet position 31, the mold transport carriage 20 is transferred from the rail 30 of the traverser 29 to the rail 32 of the pouring line 12 and poured into the mold 1 while traveling on the pouring line 12. Is done.

トラバーサ２９は移動されるので、トラバーサ２９のレール３０と注湯ライン１２のレール３２との継ぎ目にはある程度の隙間が設けられている。また、注湯ライン１２のレール３２は製作上、分割して基台上に固定されているが、製作公差、熱膨張を考慮して継ぎ目に隙間が設けられている。

Further, the rail 32 of the pouring line 12 is divided and fixed on the base for manufacturing, but a gap is provided in the seam in consideration of manufacturing tolerance and thermal expansion.
JP 2006-326660 A (paragraphs [0012], [0013], [0017], and [FIG. 1], [FIG. 2])

従来の鋳型搬送台車では、左右の前輪及び左右の後輪の車軸が夫々走行方向において同一軸線上に配置されているので、左右の前輪又は左右の後輪がレールの継ぎ目を通過するとき隙間に同時に落ち込み、鋳型搬送台車が瞬間的に沈んで強いショックが発生する。特に、往復動するトラバーサのレールとライン側のレールとの継ぎ目の隙間は大きくてショックが大きくなるので、鋳型搬送台車に載置された注湯前の鋳型に砂崩れが生じ砂噛みを生じる虞があった。また、レールの継ぎ目部分が該ショックにより早く摩耗、変形して段差が発生し、益々ショックが助長される。そして、かかるショックによる車輪、レールの損傷に費やす保全費用が高くなる問題があった。   In the conventional mold transport carriage, the left and right front wheels and the left and right rear wheel axles are arranged on the same axis in the traveling direction, so that the left and right front wheels or the left and right rear wheels are spaced apart when passing through the rail joint. At the same time, the mold falls, and the mold transport cart sinks momentarily and a strong shock occurs. In particular, the gap between the reciprocating traverser rail and the rail on the line side is large and the shock becomes large, so there is a risk that sand collapse will occur in the mold before pouring and placed on the mold transport carriage, causing sand biting. there were. Further, the joint portion of the rail is quickly worn and deformed by the shock, and a step is generated, which further promotes the shock. And there existed a problem that the maintenance expense spent on the damage of the wheel and rail by such a shock became high.

本発明は、継ぎ目に隙間が設けられた左右一対のレール上を左右の前輪及び左右の後輪の転動によって円滑に走行可能な鋳型搬送台車を提供することである。   An object of the present invention is to provide a mold transport carriage that can smoothly travel on a pair of left and right rails provided with a gap at a seam by rolling of left and right front wheels and left and right rear wheels.

上記の課題を解決するため、請求項１に記載の発明の構成上の特徴は、左右一対のレール上を左右の前輪及び左右の後輪が夫々転動して移動する鋳型搬送台車において、前記左右の前輪の車軸、及び前記左右の後輪の車軸が前記左右一対のレールの継ぎ目の隙間より大きい所定距離だけ走行方向に夫々ずらされていることである。   In order to solve the above-described problem, the structural feature of the invention described in claim 1 is that in the mold transport cart in which the left and right front wheels and the left and right rear wheels roll and move on a pair of left and right rails, The axles of the left and right front wheels and the axles of the left and right rear wheels are shifted in the traveling direction by a predetermined distance larger than the gap between the joints of the pair of left and right rails.

上記のように構成した請求項１に係る発明においては、左右一対のレール上を転動する鋳型搬送台車の左右の前輪及び左右の後輪の車軸が前記左右一対のレールの継ぎ目の隙間より大きい所定距離だけ走行方向に夫々ずらされているので、左右の前輪又は左右の後輪がレールの継ぎ目を通過するときに同時に隙間に落ち込むことがなく、左右の前輪が時間差を置いてレールの継ぎ目を通過し、同様に、左右の後輪も時間差を置いてレールの継ぎ目を通過するので、鋳型搬送台車がレールの継ぎ目を通過するときに受けるショックを緩和することができる。これにより、鋳型搬送台車に載置された注湯前の鋳型の砂崩れを防止することができ、さらに、レールの継ぎ目での摩耗、変形が減少して車輪、レールの保全費用を低減することができる。   In the invention according to claim 1 configured as described above, the axles of the left and right front wheels and the left and right rear wheels of the mold conveyance carriage rolling on the pair of left and right rails are larger than the gap between the seams of the pair of left and right rails. Since the left and right front wheels or the left and right rear wheels pass through the rail joint, they do not fall into the gap at the same time. Similarly, since the left and right rear wheels also pass through the rail joint with a time difference, the shock received when the mold transport carriage passes through the rail joint can be reduced. As a result, it is possible to prevent sand crushing of the mold before pouring which is placed on the mold transport carriage, and further, wear and deformation at the joint of the rail can be reduced to reduce the maintenance cost of the wheel and rail. it can.

以下本発明の実施の形態に係る鋳型搬送台車を図１乃至図３に基づいて説明する。１０は、例えば注湯ラインで、注湯ライン１０には、左右一対の固定レール１１が基台１３上に所定間隔を置いて長手方向で分割して固定されている。分割された固定レール１１の継ぎ目１２は基台１３上に配置され、継ぎ目１２には隙間α１が設けられている。   Hereinafter, a mold carrier cart according to an embodiment of the present invention will be described with reference to FIGS. Reference numeral 10 denotes, for example, a pouring line, and a pair of left and right fixed rails 11 are fixed to the pouring line 10 in a longitudinal direction with a predetermined interval on the base 13. The joint 12 of the divided fixed rail 11 is arranged on the base 13, and a gap α <b> 1 is provided in the joint 12.

注湯ライン１０の入口側には、一対のトラバーサ用レール１４が一対の固定レール１１と直角な方向に延設されている。１５は、往復動されるトラバーサで、トラバーサ１５の４隅に回転可能に支承された車輪１６がトラバーサ用レール１４上を転動して図略の鋳枠合せ位置と注湯ライン１０の入口と整列する入口位置１７との間で往復動される。トラバーサ１５の上面には、入口位置１７において、注湯ライン１０の一対の固定レール１１と整列する左右一対の移動レール１８が設けられている。トラバーサ１５は往復動するので、トラバーサ１５の一対の移動レール１８と注湯ライン１０の一対の固定レール１１との継ぎ目１９の隙間α２は隙間α１より大きく設定されている。   On the inlet side of the pouring line 10, a pair of traverser rails 14 extend in a direction perpendicular to the pair of fixed rails 11. Reference numeral 15 denotes a reciprocating traverser. Wheels 16 rotatably supported at the four corners of the traverser 15 roll on the traverser rail 14, and a cast frame alignment position (not shown) and an inlet of the pouring line 10 are shown. It is reciprocated between the aligned inlet positions 17. On the upper surface of the traverser 15, a pair of left and right moving rails 18 aligned with the pair of fixed rails 11 of the pouring line 10 are provided at the entrance position 17. Since the traverser 15 reciprocates, the clearance α2 of the joint 19 between the pair of moving rails 18 of the traverser 15 and the pair of fixed rails 11 of the pouring line 10 is set to be larger than the clearance α1.

注湯ライン１０の固定レール１１上には、複数の鋳型搬送台車２０が走行可能に装架されている。各鋳型搬送台車２０上には、鋳型２５が載置されている。鋳型搬送台車２０の下面４隅には、車軸固定部２１が下方に突出して一体的に設けられ、各車軸固定部２１には車軸２２が水平横方向に突設されている。前方の車軸２２には左右一対の前輪２３fl，２３frが軸受により回転可能に支承され、後方の車軸２２には左右一対の後輪２３rl，２３rrが軸受により回転可能に支承されている。左前輪２３flの車軸２２が右前輪２３frの車軸２２より走行方向にトラバーサ１５の一対の移動レール１８と注湯ライン１０の一対の固定レール１１との継ぎ目１９の隙間α２より大きい所定距離aだけ前方にずらされており、左後輪２３rlの車軸２２が右後輪２３rrの車軸２２より走行方向に所定距離aだけ前方にずらされている。所定距離ａは、鋳型搬送台車２０が走行するレールに設けられた継ぎ目の最大の隙間より大きく、かつ鋳型搬送台車２０の走行に支障をきたさない距離とする。また、左右前輪２３fl，２３frで車軸２２がずらされる所定距離と後輪２３rl，２３rrで車軸２２がずらされる所定距離とが相違してもよい。   On the fixed rail 11 of the pouring line 10, a plurality of mold transport carriages 20 are mounted so as to be able to travel. A mold 25 is placed on each mold transport carriage 20. At the four corners of the lower surface of the mold transport carriage 20, an axle fixing portion 21 protrudes downward and is integrally provided, and an axle 22 protrudes horizontally from each axle fixing portion 21. A pair of left and right front wheels 23fl and 23fr are rotatably supported by bearings on the front axle 22, and a pair of left and right rear wheels 23rl and 23rr are rotatably supported by bearings on the rear axle 22. The axle 22 of the left front wheel 23fl is ahead of the axle 22 of the right front wheel 23fr by a predetermined distance a greater than the clearance α2 of the joint 19 between the pair of moving rails 18 of the traverser 15 and the pair of fixed rails 11 of the pouring line 10 in the traveling direction. The axle 22 of the left rear wheel 23rl is shifted forward by a predetermined distance a in the traveling direction from the axle 22 of the right rear wheel 23rr. The predetermined distance a is larger than the maximum gap of the joint provided on the rail on which the mold transport carriage 20 travels, and is a distance that does not hinder the travel of the mold transport carriage 20. The predetermined distance by which the axle 22 is shifted by the left and right front wheels 23fl and 23fr may be different from the predetermined distance by which the axle 22 is shifted by the rear wheels 23rl and 23rr.

次に、上記実施の形態の作動を説明する。トラバーサ１５が図略の鋳枠合せ位置に停止されると、トラバーサ１５の一対の移動レール１８上に装架された鋳型搬送台車２０上に鋳型２５が載置される。その後、トラバーサ１５が入口位置１７に移動されると、一対の移動レール１８が一対の固定レール１１と整列され、一対の移動レール１８及び一対の固定レール上に装架された複数の鋳型搬送台車２０が搬送装置によって一ピッチ移動される。これにより、トラバーサ１５上の鋳型搬送台車２０は、トラバーサ１５の一対の移動レール１８から注湯ライン１２の固定レール１１に乗り移され、注湯ライン１２では注湯前の鋳型が載置された鋳型搬送台車２０が注湯位置に移動されて注湯される。   Next, the operation of the above embodiment will be described. When the traverser 15 is stopped at the casting frame alignment position (not shown), the mold 25 is placed on the mold transport carriage 20 mounted on the pair of moving rails 18 of the traverser 15. After that, when the traverser 15 is moved to the entrance position 17, the pair of moving rails 18 are aligned with the pair of fixed rails 11, and the plurality of mold transport carriages mounted on the pair of moving rails 18 and the pair of fixed rails. 20 is moved by one pitch by the conveying device. As a result, the mold transport carriage 20 on the traverser 15 is transferred from the pair of moving rails 18 of the traverser 15 to the fixed rail 11 of the pouring line 12, and the casting mold on which the mold before pouring is placed is placed on the pouring line 12. The transport cart 20 is moved to the pouring position and poured.

鋳型搬送台車２０では、左右の前輪２３fl，２３frの車軸２２、及び左右の後輪２３rl，２３rrの車軸２２が、トラバーサ１５の一対の移動レール１８と注湯ライン１０の一対の固定レール１１との継ぎ目１９の隙間α２より大きい所定距離aだけ走行方向に夫々ずらされているので、左右の前輪２３fl，２３fr又は左右の後輪２３rl，２３rrが、一対の移動レール１８と一対の固定レール１１との継ぎ目１９、又は分割された固定レール１１間の継ぎ目１２を通過するときに同時に隙間α２又は隙間α１に落ち込むことがない。このように、左右の前輪２３fl，２３fr、及び左右の後輪２３rl，２３rrが時間差を置いて継ぎ目１９，１２を通過するので、鋳型搬送台車２０がレールの継ぎ目１９，１２、特に隙間α２が大きい継ぎ目１９を通過するときに受けるショックを緩和することができる。これにより、鋳型搬送台車２０に載置された注湯前鋳型２５の砂崩れを防止することができ、さらに、固定レール１１と移動レール１８との間の継ぎ目１９及び分割された固定レール１２間の継ぎ目１２での摩耗、変形が減少して車輪２３、固定レール１１及び移動レール１８の保全費用を低減することができる。   In the mold transport carriage 20, the axles 22 of the left and right front wheels 23 fl and 23 fr and the axles 22 of the left and right rear wheels 23 rl and 23 rr are connected to the pair of moving rails 18 of the traverser 15 and the pair of fixed rails 11 of the pouring line 10. The left and right front wheels 23fl and 23fr or the left and right rear wheels 23rl and 23rr are respectively displaced between the pair of movable rails 18 and the pair of fixed rails 11 because they are shifted in the traveling direction by a predetermined distance a larger than the clearance α2 of the joint 19. When passing through the joint 19 or the joint 12 between the divided fixed rails 11, it does not fall into the gap α2 or the gap α1 at the same time. As described above, the left and right front wheels 23fl and 23fr and the left and right rear wheels 23rl and 23rr pass through the joints 19 and 12 with a time difference, so that the mold transport carriage 20 has a large rail joint 19 and 12, particularly the gap α2. The shock received when passing through the joint 19 can be reduced. As a result, it is possible to prevent sand crushing of the mold 25 before pouring which is placed on the mold transport carriage 20, and between the joint 19 between the fixed rail 11 and the moving rail 18 and the divided fixed rail 12. The wear and deformation at the joint 12 are reduced, and the maintenance cost of the wheel 23, the fixed rail 11 and the moving rail 18 can be reduced.

図４に示す他の実施の形態では、左前輪２３flの車軸２２が右前輪２３frの車軸２２よりトラバーサ１５の一対の移動レール１８と注湯ライン１０の一対の固定レール１１との継ぎ目１９の隙間α２より大きい所定距離aだけ走行方向後方にずらされており、左後輪２３rlの車軸２２が右後輪２３rrの車軸２２より所定距離aだけ走行方向前方にずらされている。他の構成は上記実施の形態と同じであるので説明を省略する。   In another embodiment shown in FIG. 4, the axle 22 of the left front wheel 23fl has a gap between the pair of moving rails 18 of the traverser 15 and the pair of fixed rails 11 of the pouring line 10 than the axle 22 of the right front wheel 23fr. The axle 22 of the left rear wheel 23rl is shifted forward by a predetermined distance a from the axle 22 of the right rear wheel 23rr by a predetermined distance a greater than α2. Since other configurations are the same as those of the above embodiment, the description thereof is omitted.
