Description

本発明は、リング状成形体をクレーンなどで吊るための吊り下げ用治具に関する。   The present invention relates to a hanging jig for hanging a ring-shaped molded body with a crane or the like.

従来より、例えば、航空機用のエンジンの一部として複雑な段付きテーパを有する比較的大型のリング状成形体が用いられるが、このリング状成形体は、製造過程において、エッチング処理を施されたり、搬送されたりする際には、吊り下げ用治具を介してクレーンなどで吊り下げされている。   Conventionally, for example, a relatively large ring-shaped molded body having a complicated step taper has been used as a part of an aircraft engine. However, this ring-shaped molded body is subjected to an etching process in the manufacturing process. When being conveyed, it is suspended by a crane or the like via a hanging jig.

このリング状成形体を吊り下げるには、クレーンに上端部が鉛直方向へ回転可能に取り付けられると共に、下端部にリング状成形体を係止する係止部を有する複数のアームを備える吊り下げ用治具が使用されている。この吊り下げ用治具を使用してリング状成形体を移動させるには、１つのリング状成形体を複数のアームの係止部で係止し、この状態でクレーンを駆動させて移動させている。
この吊り用治具のように、荷物などの対象物を吊るための吊り下げ用治具が特許文献１および２に開示されている。 In order to suspend the ring-shaped molded body, the upper end of the ring-shaped molded body is attached so as to be rotatable in the vertical direction, and the suspension is provided with a plurality of arms having locking portions for locking the ring-shaped molded body at the lower end. A jig is used. In order to move the ring-shaped molded body using this hanging jig, one ring-shaped molded body is locked by the locking portions of a plurality of arms, and the crane is driven and moved in this state.

しかしながら、従来の吊り下げ用治具は、一度に１つの対象物しか吊ることができないため、このような吊り下げ治具を使用して多数のリング状成形体にエッチング処理を行ったり、多数のリング状成形体を搬送したりするには、作業効率が悪く、多くの時間がかかっている。   However, since the conventional hanging jig can hang only one object at a time, it is possible to etch a large number of ring-shaped molded bodies using such a hanging jig, In order to convey the ring-shaped molded body, work efficiency is poor and it takes a lot of time.

本発明は、上述する事情に鑑みてなされたもので、同時に複数のリング状成形体を吊ることができる吊り下げ用治具を提供することを目的とする。   This invention is made | formed in view of the situation mentioned above, and it aims at providing the jig | tool for suspension which can suspend several ring-shaped molded objects simultaneously.

上記目的を達成するため、本発明に係る吊り下げ用治具は、吊り下げ手段に吊り下げられて複数のリング状成形体を鉛直方向に並べて吊り下げる吊り下げ用治具であって、吊り下げ手段に吊り下げられるブロックと、該ブロックに上端部が鉛直方向に回転可能に取り付けられると共に上端部よりも下側に前記リング状成形体を係止する係止部を有する複数のアームを有する吊り下げアーム群とを備え、前記吊り下げアーム群が、前記ブロックを中心に周方向に沿って複数取り付けられ、前記複数の吊り下げアーム群どうしの間では、前記アームの係止部の取り付け高さが異なっていることを特徴とする。   In order to achieve the above object, a hanging jig according to the present invention is a hanging jig that is hung by a hanging means and hangs a plurality of ring-shaped molded products arranged in a vertical direction. A suspension having a block suspended by the means, and a plurality of arms having an upper end attached to the block so as to be rotatable in the vertical direction and having a locking portion for locking the ring-shaped molded body below the upper end. A plurality of suspension arm groups, and a plurality of the suspension arm groups are attached along the circumferential direction around the block, and the attachment height of the locking portion of the arm is between the plurality of suspension arm groups. Are different.

本発明では、吊り下げアーム群が、ブロックを中心に周方向に沿って複数取り付けられ、複数の吊り下げアーム群どうしの間では、アームの係止部の取り付け高さが異なっていることにより、複数の吊り下げアーム群の係止部がそれぞれ異なる高さでリング状成形体を係止するため、複数のリング状成形体を鉛直方向に並べて同時に吊り下げることができる。   In the present invention, a plurality of suspension arm groups are attached along the circumferential direction around the block, and between the plurality of suspension arm groups, the mounting heights of the locking portions of the arms are different, Since the locking portions of the plurality of suspension arm groups lock the ring-shaped molded bodies at different heights, the plurality of ring-shaped molded bodies can be suspended in the vertical direction at the same time.

また、本発明に係る吊り下げ用治具では、前記吊り下げアーム群は、該吊り下げアーム群の前記複数のアームどうしの開き角度をある角度に保持する角度保持部材を備えていてもよい。
このように、吊り下げアーム群は、吊り下げアーム群の複数のアームどうしの開き角度をある角度に保持する角度保持部材を備えていることにより、複数のアームどうしの開き角度をある角度よりも小さくなることを防ぐことができるため、複数のアーム間にリング状成形体を設置しやすい。
また、一の吊り下げアーム群でリング状成形体を吊り下げるため、アームの係止部をリング状成形体に係止させるとき、他の吊り下げアーム群のアームがリング状成形体に干渉しないように、それらアームを開き状態すなわち待機状態にすることができる。 In the hanging jig according to the present invention, the hanging arm group may include an angle holding member that holds an opening angle between the arms of the hanging arm group at a certain angle.
As described above, the suspension arm group includes the angle holding member that holds the opening angles of the plurality of arms of the suspension arm group at a certain angle, so that the opening angles of the plurality of arms are more than the certain angle. Since it can prevent becoming small, it is easy to install a ring-shaped molded object between a plurality of arms.
Also, since the ring-shaped molded body is suspended by one hanging arm group, when the locking portion of the arm is locked to the ring-shaped molded body, the arms of the other hanging arm groups do not interfere with the ring-shaped molded body. Thus, the arms can be in an open state, that is, a standby state.

本発明によれば、複数のリング状成形体を同時に吊り下げることができるため、リング状成形体を製造する際のエッチング作業や運搬などにかかる時間を短縮することができる。   According to the present invention, since a plurality of ring-shaped molded bodies can be suspended at the same time, it is possible to shorten the time required for etching work and transportation when manufacturing the ring-shaped molded body.

このとき、第１アーム３の第１屈曲部材１３は、第２アーム５の第２屈曲部材１５よりも高さ方向に短く形成されている。このため、第１アーム３および第２アーム５がアーム保持部材１２に取り付けられると、第１アーム３の第１係止部４は、第２アーム５の第２係止部６の上方に位置している。
これにより、第１アーム群９が第１リング状成形体２１を係止することと、第２アーム群１０が第２リング状成形体２２を係止することと、を同時に行うことができる。 At this time, the first bending member 13 of the first arm 3 is formed shorter than the second bending member 15 of the second arm 5 in the height direction. Therefore, when the first arm 3 and the second arm 5 are attached to the arm holding member 12, the first locking portion 4 of the first arm 3 is positioned above the second locking portion 6 of the second arm 5. is doing.
Thereby, the 1st arm group 9 can latch the 1st ring-shaped molded object 21, and the 2nd arm group 10 can latch the 2nd ring-shaped molded object 22 simultaneously.

また、第１アーム３の第１係止部４と第２アーム５の第２係止部６との間隔は、第１リング状成形体２１の高さ寸法よりも大きくなっている。
これにより、第１アーム３，３に係止された第１リング状成形体２１と、第２アーム５，５に係止された第２リング状成形体２２とが吊り下げられたときに、第１リング状成形体２１と第２リング状成形体２２とが接触することを防ぐことができる。 Further, the distance between the first locking portion 4 of the first arm 3 and the second locking portion 6 of the second arm 5 is larger than the height dimension of the first ring-shaped molded body 21.
Thus, when the first ring-shaped molded body 21 locked to the first arms 3 and 3 and the second ring-shaped molded body 22 locked to the second arms 5 and 5 are suspended, It can prevent that the 1st ring-shaped molded object 21 and the 2nd ring-shaped molded object 22 contact.

なお、第１アーム群９を構成する各部材は、第２アーム群１０に係止された第２リング状成形体２２と干渉しない形状に形成され、また、第２アーム群１０を構成する各部材は、第１アーム群９に係止された第１リング状成形体２１と干渉しない形状に形成されている。   In addition, each member which comprises the 1st arm group 9 is formed in the shape which does not interfere with the 2nd ring-shaped molded object 22 latched by the 2nd arm group 10, and each member which comprises the 2nd arm group 10 The member is formed in a shape that does not interfere with the first ring-shaped molded body 21 locked to the first arm group 9.

第２角度保持部材８は、棒状の部材で、一方の端部８ａが第２アーム群１０の一方の第２アーム５に鉛直方向に回転可能に保持されて、他方の端部８ｂが、他方の第２アーム５に着脱可能に構成されている。
なお、第１角度保持部材７および第２角度保持部材８は、図示しないターンバックルなどを備えていて、それぞれ延在方向に長さ調整可能としてもよい。このように、第１角度保持部材７の長さが調整可能であることにより、一対の第１アーム３，３どうしの開き角度を所望の角度に調整することができ、また第２角度保持部材８の長さが調整可能であることにより、一対の第２アーム５，５どうしの開き角度を所望の角度に調整することができる。 As shown in FIGS. 1 and 2, the first angle holding member 7 is a rod-like member, and one end 7 a is held by one first arm 3 of the first arm group 9 so as to be rotatable in the vertical direction. The other end 7 b is configured to be detachable from the other first arm 3.
The second angle holding member 8 is a rod-shaped member, and one end portion 8a is rotatably held by one second arm 5 of the second arm group 10 in the vertical direction, and the other end portion 8b is The second arm 5 is configured to be detachable.
In addition, the 1st angle holding member 7 and the 2nd angle holding member 8 are provided with the turnbuckle etc. which are not shown in figure, and are good also as length adjustment in the extending direction, respectively. In this way, the length of the first angle holding member 7 can be adjusted, whereby the opening angle between the pair of first arms 3 and 3 can be adjusted to a desired angle, and the second angle holding member can be adjusted. Since the length of 8 can be adjusted, the opening angle between the pair of second arms 5 and 5 can be adjusted to a desired angle.
