される。2. Description of the Related Art When a new wire rope is wound around a winch of a crane, the new wire rope is
It is wound on a wooden drum, and the end of the wire rope is set on the drum of the crane and wound by the rotating force of the crane winch.At that time, the load tension is applied to the wire rope to winch the crane. It is required to wind tightly and tightly in order. For that purpose, for example, for a wire rope having a large diameter such as 30 mm, the load tension is required to be 10 t or more.

込んでしまって巻き出し不能となる問題がある。According to such a conventional technique, a large load is applied to the drawn wire rope, and therefore the rotation of the wooden drum is controlled by a large braking force. Due to the load tension, the wire rope pulled out into the layer below the wire rope wound in several layers on the wooden drum interrupts and enters, and it becomes a disordered winding state, causing a problem of scratching the wire rope, In a severe case, there is a problem that it cannot be unrolled because it interrupts firmly.

Is arranged, the wire rope is wound around the body of the control drum several times in an aligned state, and the rotation of the body of the control drum is controlled by the control means.

ープはウインチにしっかりと巻き取られることになる。According to the above construction, by applying braking to the body of the control drum, friction between the body and the wire rope is increased, and the body is wound around the body by the spiral derivative attached to the inner surface of the winding side plate. The wire ropes to be inserted are surely wound in an aligned state one by one, so that when the wire ropes wound several times are subjected to the pulling force of the winch, the wound wire ropes come into close contact with each other. At the same time, the wire is tightly wound around the torso and a braking action is exerted. In this state, the wire rope that is successively fed out is securely wound around the winch.

Reference numeral 5 denotes a metal control drum, the rotation of which is controlled by a shaft 7 provided through a side plate 10 that does not rotate on the winding side, and a rotation control device (not shown) different from the above is connected to the shaft 7. . On the inner surface of the side plate 10 on the winding side of the control drum 5, the wall thickness is sequentially increased from the winding side and the body 6 is spirally formed.
A spiral derivative 9 having a take-in opening 8 formed between a front end and a rear end of a circumference of is attached. The wire rope 3 guided by the spiral derivative 9 is
It is wound several times in an aligned state, and its tip is set on a winch of a crane (not shown).

Is wound around the winch of the crane, and at that time, the wooden drum 1 and the control drum 5 are braked, and the tensile force A applied to the wire rope 3 from the wooden drum 1 is greater than that from the control drum 5. The pulling force B applied to the wire rope 3 is smaller than the pulling force B, and the pulling force of the winch is received by the control drum 5 so that the pulling force of the winch is not directly transmitted to the wooden drum 1.

なる。This applies proper braking to the body 6 of the control drum 5 by not shown braking means, for example, general braking means for braking the brake shoe by the band brake or the disc by the brake pad. As a result, the friction between the body 6 and the wire rope 3 that is fed out increases, and the wire rope 3 wound several times in the aligned state is strongly wound around the body when the pulling force of the winch acts, and the wire ropes are adjacent to each other. The ropes 3 will come into firm contact with each other and the braking action will work.

むようなことがなくなる。Therefore, the braking action of the wire rope 3 by the control drum 5 is not limited to the braking ability of the barrel 6, but the number of windings around the barrel 6 is a major factor in the braking action. As a result, the pulling force of the winch is controlled by the control drum 5, and the strong pulling force is not applied to the wire rope 3 behind the control drum 5, and the wire rope 3 is wound around the layers of the wooden drum 1. It will not interrupt the lower layer.

Like the side plate 10 on the winding side, it may not rotate, or may rotate integrally with the body 6. further,
The control drum 5 may become hot during the braking operation of the wire rope 3 due to its frictional resistance. Therefore, it is preferable to put a cooling medium in the control drum 5, which can prevent the braking force from decreasing due to heating. Also,
It is conceivable that the braking force may decrease due to heating even in the braking means (not shown) of the control drum, and in this case as well, cooling means may be provided as needed. You should put it in.

Place a control drum with a spiral derivative on the non-rotating side plate on the winding side between the drum on which the wire rope is wound and the winch that winds this wire rope, and align the wire rope on the body of this control drum. By controlling the rotation of this control drum while winding it several times in the state, the tension of the winch is received by the control drum, and the pulling force of the winch is not directly transmitted to the drum side where the wire rope is wound. It has an effect that it does not bite into the layer below the drum on which the wire rope is wound, and the wire rope of the drum is prevented from becoming irregularly wound.

Further, since the winch can wind the wire rope with a sufficient pulling force, it has an effect that the wire rope can be firmly wound tightly on the winch.
