To use pulleys and position sensors to automatically carry out the operations of winding up, winding out, and stopping and thereby easily add an automatic tension function to a generic winch, thus providing a low cost winch with a quick turn-around time. Two pulleys across which a wire rope spans are configured such that the distance between the pulleys can be modified in accordance with the tension of the wire rope. If the tension increases, the distance between the pulleys decreases and a position sensor operates, as a result of which the winch shifts to winding out operation and the distance between the pulleys is increased by the action of force from rodless cylinders. If the tension decreases, the distance between the pulleys increases and a different position sensor operates, as a result of which the winch shifts to winding up operation and the distance between the pulleys decreases. These operations to let out and pull in the wire rope are performed repeatedly on the basis of the operation of the two position sensors, thereby controlling the tension of the wire rope to a constant tension.

    提供一种利用滑轮和位置传感器执行自动实施卷扬、放下和停止这三个动作,因此容易使通用的卷扬机装置具有自动张紧功能,并且廉价且交货时间短的的卷扬机。本发明的卷扬机装置具有两个悬挂有绳索的滑轮,其构成为能够根据绳索的张力来改变滑轮彼此之间的距离,张力增大时滑轮彼此之间的距离变小,位移传感器执行动作,卷扬机转变为放下动作,且通过无杆气缸的力的作用使得滑轮之间的距离增大;张力变小时滑轮彼此之间的距离增大,另一个位置传感器执行动作,由此卷扬机转变为卷扬动作,滑轮彼此之间的距离变小,通过因2个位置传感器的动作从而反复进行以上的绳索回退动作和绳索牵拉动作,从而将绳索的张力控制在一定的张力状态。
