船舶において抜錨した錨を捲き上げる時、錨鎖
がねじれた状態になつて上ることがある。本考案
はこのようなねじれた錨鎖のよりを戻す際に使用
し、錨鎖のねじれを容易に修正できるようにした
錨鎖のより戻し治具に関するものである。[Detailed description of the invention] When hoisting up an anchor that has been pulled out on a ship, the anchor chain may become twisted and hoist up. The present invention relates to an anchor chain untwisting jig which is used to untwist such a twisted anchor chain and which allows the twisting of the anchor chain to be easily corrected.
錨を昇降させるために使用する錨鎖の捲き上げ
捲き上げは、錨鎖と噛み合う鎖歯車によつて行な
われる。このための装置を第１図について説明す
ると、１は錨鎖、２は鎖歯車、３は鎖歯車２に対
するブレーキ、４は制鎖器である。 Hoisting and hoisting of the anchor chain used to raise and lower the anchor is performed by a chain gear that meshes with the anchor chain. The apparatus for this purpose will be explained with reference to FIG. 1: 1 is an anchor chain, 2 is a chain gear, 3 is a brake for the chain gear 2, and 4 is a restrainer.
鎖歯車２は第２図にも示すように、両側に対向

斜面６（第１図参照）になつている。対向して形
成されている爪５，５の間は溝７（第２図参照）
になつていて、この溝７内に錨鎖１が嵌入し、錨
鎖１と鎖歯車２とが噛み合うようになつている。 As shown in FIG. 2, the chain gear 2 has pawls 5 formed opposite to each other on both sides, and the circumferential direction of the pawls 5 forms an inclined surface 6 (see FIG. 1). Between the claws 5 and 5 which are formed opposite to each other is a groove 7 (see Figure 2).
The anchor chain 1 fits into this groove 7, and the anchor chain 1 and the chain gear 2 mesh with each other.

制鎖器４との間に無理が生ずることになる。 When anchoring in Fig. 1, when the clutch (not shown) between the chain gear 2 and the brake 3 is released and the brake is loosened, the anchor chain is accelerated by the gravity of the anchor chain 1 and falls in the direction A. ,
The anchor chain 1 spreads outward due to centrifugal force, and the chain gear 2
The anchor chain 1 is often twisted because it comes off the hook 5 and the groove (not shown) of the restrainer 4 and descends in a meandering manner. By the way, the anchor chain 1 is connected at each joint with a Kenter shaft 8, and since this Kenter shaft 8 is usually larger than the anchor chain 1, the Kenter shaft 8 is attached to the groove 7 of the chain gear 2 and the groove of the restrainer 4. cannot be inserted.
For this reason, the Kenter shaft 8 must be in contact with the chain gear 2 and the restraint device 4 in a horizontally planar state. However, when the anchor chain 1 is twisted, the Kenter shaft 8 is placed in a vertical position as shown in FIG. 1, and strain occurs between the chain gear 2 and the restraint 4.
このように錨鎖１にねじれが生じた場合従来に

錨鎖１の向きを変えてねじれを戻すこともあつ
た。 Conventionally, when the anchor chain 1 is twisted, the chain gear 2 is slightly rotated clockwise to move the anchor chain 1 in the direction B shown in FIG.
After loosening the anchor chain 1 between the anchor chain 1 and the restrainer 4, insert the levers 9 into 4 to 5 links that make up the anchor chain 1, rotate the chain gear 2 while changing the direction of the anchor chain 1, and tighten the anchor chain. 1
This work requires 4 to 5 workers, and if the links that make up the anchor chain 1 are large, they can be twisted by changing the direction of the anchor chain 1 while pulling the lever 9 with a chain block. I could have returned it.
このような従来の作業は、錨鎖１が重くしかも
鎖歯車２の溝７にはまつていくため困難な作業で
あり、多くの人力を要すると共に安全上に問題が
あつた。 Such conventional work is difficult because the anchor chain 1 is heavy and gets stuck in the groove 7 of the chain gear 2, requiring a lot of human power and posing safety problems.
本考案はこのような従来の欠点を除去し、少な

のより戻し治具を提供するものである。 The purpose of the present invention is to eliminate such conventional drawbacks and to make it possible to safely untwist an anchor chain with a small number of workers, and to provide an anchor chain untwisting jig that is attached to a chain gear and used. It is.

うにワイヤ２４を適宜の個所に固縛する。 An embodiment of the present invention will be described with reference to FIGS. 4 and 5. This jig 20 includes a first rod 21,
and a second rod 22 fixed in a direction perpendicular to both ends of the first rod 21, and a lug 23 integrally formed on one side of the second rod 22. A wire 24 is attached. The outer dimensions of the first rod 21 are such that the first rod 21 faces in the circumferential direction of the chain gear 2 and can be inserted between the pawls 5, 5, as shown in FIG. There is. Moreover, the inner dimensions of the second rod 22 are such that when the first rod 21 is inserted between the claws 5, 5 as described above, the second rod 22, ，
22, and is dimensioned so that both ends of the second rod 22 engage with the inclined surface 6 of the claw 5, as shown in FIG. When untwisting the anchor chain 1 using the jig 20, first support the dead weight of the anchor chain 1 in the A direction with the stopper 25 as shown in FIG. The anchor chain 1 between the chain gear 2 and the restrainer 4 is loosened. In this state, insert the first rod 21 of the jig 20 between the pawls 5, 5 of the chain gear 2, and
Both ends of the rod 22 are engaged with the inclined surfaces 6 of the claws 5. Then, the wire 24 is secured at an appropriate location so that the jig 20 does not fall off from the chain gear 2.

る。 After doing this, when the chain gear 1 is rotated counterclockwise in FIG. 1, the anchor chain 1, which has been loosened between the chain gear 1 and the restrainer 4, is pulled by the chain gear 2 It comes to rest on the jig 20. In this case, since the anchor chain 1 is in an upright position, the anchor chain 1 can be rotated 90 degrees with the lever 9 to correct the twist, as shown in FIG. Second rod 22 of jig 20
has both ends engaged with the inclined surface 6 of the claw 5,
The jig 20 is attached to the chain gear 2 in a stable state. The anchor chain 1, which stands on the jig 20, uses the stable jig 20 as a base, and one worker can lift the anchor chain 9 using the stable jig 20.
The chain gear 2 can be untwisted, and only two workers are required including the person who rotates the chain gear 2.
本考案は上述のように少ない作業者で錨鎖のよ
りを少ない労力と短い作業時間で安全に戻すこと
ができる。また治具は小型軽量で、取付作業も容
易に行なうことができる。 As described above, the present invention allows the anchor chain to be safely untwisted with less labor and shorter working time by fewer workers. Furthermore, the jig is small and lightweight, making installation work easy.
