本発明はボイスＩ・に関し、特に限られた頭上スペース

に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hoist that can be operated in a confined space with limited headroom.
原子力産業では、照躬済核燃月の輸送は燃料を容器の中

つ巻付は操作及び繰出し操作中ホイストケーブルの重な
りを避けることが望ましい。In the nuclear industry, shipping of calibrated nuclear fuel involves placing the fuel into a container and positioning the container into a shipping flask. The flask has a removable closure at one end and a voice at the opposite end so that when the flask is upright, a hoist can be used to lift the container into and out of the flask. Since hoisting operations are frequently performed in locations with limited head space, it is desirable to make the hoist as compact as possible and to avoid overlapping of the hoist cables during winding and unwinding operations.

る。According to the invention, the hoist is arranged along the drive shaft
! It has a hollow cylindrical body that can move in the III-line direction and rotate with the drive shaft, and this cylindrical body has a helical groove on its outer surface for receiving the cable, and this helical groove cooperates with a complementary fixing part shrine. The cylindrical body and the threaded connection part are formed by this, whereby the cylindrical body is rotated by the shaft to move the cylindrical body in the axial direction along the shaft, and the winding and unwinding operations are performed so that the cable is connected to the cylinder. Staying at the same axial position with respect to the body is considered an ll-7 sign.
その結果、ケーブルカミ円筒体に対して同じ軸線方向位
置にとどまり、円筒体の軸線方向移動により、巻付は及
び繰出し中ケーブルを円筒体螺旋溝をたどらせる。As a result, the cable clip remains in the same axial position relative to the cylinder, and axial movement of the cylinder causes the cable to follow the cylinder helical groove during winding and unwinding.
本発明を添付図面を参照して、例示として更に説明する
。The invention will be further described, by way of example, with reference to the accompanying drawings, in which: FIG.

の端の取外可能な閉鎖体を通してフラスコに昇降出し入
れすることができる。The hoist has a hollow cylindrical body 1 attached to a shaft 2, and the shirts 1-2 are rotatably supported by a bearing assembly 3 mounted on a support member 4. The support member 4 is the end closure of a transport flask for receiving nuclear fuel. The shaft 2 is connected via a suitable coupling to a drive motor mounted on a support member 4. In FIG. 1, two steel ropes or cables 5 and 6 are wound around a cylinder 1, the ends of the ropes extending from the cylinder and supporting parts 4.
The load in the flask is guided through the opening in J4. When rotating the cylinder 1, loads can be moved up and down the flask through a removable closure at the opposite end of the flask.
円筒体１にはローブ５及び６の夫々を受入れる２木の螺
旋溝７及び８が形成されている。螺旋溝は、支持部材４
に固定されている環状支持ブラケソＩ・１１及び１２で
夫々支承されている案内ローラ９及び１０と協働する。Two spiral grooves 7 and 8 are formed in the cylindrical body 1 to receive the lobes 5 and 6, respectively. The spiral groove is the support member 4
It cooperates with guide rollers 9 and 10, which are respectively supported on annular support brackets I. 11 and 12, which are fixed on.
例えば、各ブラケツトば円筒体のまわりに配置され且つ

に移動することができる。As can be seen in FIG. 2, the shaft 2 is of square cross section and the cylindrical body 5 is attached to the shaft 2 by a linear bearing assembly 13. The bearing assemblies 13 are arranged in pairs, each row supported by a housing 14 fixed to the cylindrical body 1, with each bearing assembly fitted on a respective side of the square shaft 2. This allows the cylindrical body to be rotationally coupled with the shirt i and to be moved axially along the shaft.
第１図では、円筒体は、ロープを円筒体に巻付けて螺締
溝内に位置させた端位置で示されている。In FIG. 1, the cylinder is shown in its end position with the rope wrapped around the cylinder and located within the threaded groove.

すると、ローブ５及び６が円筒体のまわりから繰出す。When the drive motor is actuated to rotate the shaft 2, the cylinder rotates and during such rotation the threaded connection consisting of the threaded groove and the guide rollers 9 and 10 and the support assembly 13
The cylindrical body is thereby moved in the axial direction along the shaft 2. Thus, in Figure 1, as the cylinder moves to the right, lobes 5 and 6 unwind from around the cylinder.
シャフト２を逆回転ざゼると、円筒体は反対方向に軸線
方向に移動し、ローブを円筒体に巻付りる。Reverse rotation of the shaft 2 causes the cylinder to move axially in the opposite direction, wrapping the lobe around the cylinder.
巻付は及び繰出し中、ロープ５及び６ば円筒体の溝をた
どって入り、重ならずに円筒体に巻付く。During winding and unwinding, the ropes 5 and 6 follow the grooves of the cylindrical body and wind around the cylindrical body without overlapping.

繰出し操作の両方の間じゅう＝・定のままである。The position of each steel lobe leaving the cylinder remains constant during both the winding and unwinding operations.

達成することができる。In the illustrated embodiment, the same effect can be achieved with only 13 rollers, such as rollers 9, using two sets of guide rollers to effect the axial movement. This can also be achieved by using only the guide roller (2).
