る。Description: TECHNICAL FIELD The present invention relates to a cable winding device used for supplying power from a fixed part to a turning part in a turning suspension beam, for example.
[従来の技術とその問題点] 従来、旋回式吊ビームでは、固定部と旋回部との間に
ケーブルを渡す場合、旋回部の旋回動に追従するように
ケーブルを弛ませておき、その弛み部分をハンガーで支
持するか、或はスリップリング装置等を使用して固定部
側ケーブルと旋回部側ケーブルを接続していた。[Prior art and its problems] In the conventional swing-type hanging beam, when a cable is passed between the fixed part and the swivel part, the cable is loosened so as to follow the swivel motion of the swivel part, and the slack Either the portion is supported by a hanger, or the cable on the fixed portion side and the cable on the rotating portion side are connected by using a slip ring device or the like.
しかしながら、前者の方法では、旋回角度が小さい場

方法では、スリップリング装置を旋回中心部に取付ける
ことになり、構造が複雑でコスト高になると共に、大型
の旋回機構を使用する必要がある等の不都合があった。However, in the former method, when the turning angle is small, the slack of the cable is small and there is no problem, but when the turning angle is large, the cable is twisted, the rubbing with the turning part occurs, and the cable is broken. To do. Further, in the latter method, the slip ring device is attached to the center of turning, and the structure is complicated and the cost is high, and it is necessary to use a large turning mechanism.

つ、コスト高となるという不都合を免れない。Therefore, as one measure to solve the conventional inconvenience, a cable winding device for a moving body such as a crane disclosed in Japanese Patent Laid-Open No. 58-125576 is applied, and its rotating drum is used as a cable winding body on the swivel side. And, the fixed drum is used as a fixed portion side cable winding drum, and the cable is moved between the two cable winding drums via a cable pulley that rotates around the turning center at a constant speed ratio with respect to the turning portion. In this case, in order to rotate the arm that supports the cable pulley on the swivel shaft at a constant speed ratio, it is necessary to attach one end of the arm to the swivel shaft via a transmission mechanism such as an eddy current clutch. However, the structure is complicated and the cost is high.

れる。[Operation] When the swivel unit 7 is swiveled to the right (clockwise direction) about the swivel axis 2, the cable 16 is wound around the cable winding drum 8B on the swivel unit 7 side as shown in FIGS. Pulley for cable
Since a force pulling 14 in the winding direction of the cable winding cylinders 8A, 8B is generated, the cable pulley 14 is moved in the same direction as the turning direction of the turning unit 7 by the component force perpendicular to the arm 10.
It is swung about the swivel axis 2 at a speed half of the swiveling speed of.

記旋回は安定したものとなる。Therefore, the rope winding cylinder 9B having the same outer diameter D 1 as the cable winding cylinders 8A and 8B also rotates in the same direction as the turning direction of the turning portion 7 at a speed half the turning speed. Meanwhile, the rope pulley 15
Rotates with the revolving unit 7 around the revolving axis 2 at the same speed in the same direction, so that the wire rope 17 is unwound from the rope winding body 9B and the outer diameter D of the rope winding body 9B is 1/2. The wire rope 17 is wound on the rope winding drum 9A on the side of the fixed portion 1 having 2 in the same amount as the unwinding amount. Therefore, the force to pull the cable pulley 14 and the cable winding drums 8A and 8B through the wire rope 17, the rope winding drum 9B, and the arm 10 to the opposite side from the cable winding direction side so that the cable tension and the wire rope tension are balanced. Therefore, the swiveling of the cable pulley 14 becomes stable.

る。On the contrary, when the turning portion 7 is turned left (counterclockwise direction), the rope pulley 15 turns together with the turning portion 7 around the turning shaft 2 at the same speed in the same direction, and the rope winding on the fixed portion 1 side. While the wire rope 17 is unwound from the body 9A,
Wire rope 17 to the rope winding drum 9B having an outer diameter D 2 2 times of the rope winding drum 9A is wound by weight rewind same amount in the same direction the rope winding drum 9B is a turning direction of the turning part 7 Since it rotates at 1/2 speed of the swiveling speed, the cable pulley 14 is rotated about the swivel axis 2 via the arm 10 in the same direction as the swivel direction of the swivel unit 7 (cable winding of the cable winding drums 8A and 8B). Turn in the direction opposite to the attaching direction) at a speed half the turning speed.
従って、ケーブル用プーリ14は、旋回部7の旋回方向
と同じ方向に旋回速度の1/2の速度で確実に追従旋回す

せることができる。Therefore, the cable pulley 14 surely follows and turns in the same direction as the turning direction of the turning portion 7 at a speed of 1/2 of the turning speed, so that the cable 16 is placed under the tension balanced with the wire rope tension. Through the fixed portion 1 side cable winding cylinder 8A and the swivel portion 7 side cable winding cylinder 8B,
It is possible to rewind from one of the cable winding cylinders 8A and 8B and wind it to the other.
