    • PURPOSE: A drive pulley, and a wire saw equipage and a cutting method using the drive pulley are provided to enable a cutting device using wire saw to be much leaner and lighter, and to improve the capability thereof. CONSTITUTION: The drive equipment which becomes from the drive pulley(12) is attached to the prop supported by the base stand. The drive pulley consists of a stator(21) which is on a fixed axis, an annular rotor(22) prepared on the outer perimeter of the stator, and a ring shaped pulley part(29) prepared on the outer perimeter of the rotor. The wire saw(5) having a ring part(5a) sintered diamond abrasive particle in the wire rod such as a wire etc. is arranged and wound in a groove(28) formed in the outer perimeter of pulley part. The wire saw wound to the pulley part is driven with the rotating force of the rotor generated by applying electric power to the drive pulley, thus the wire saw cut the material via the contact between the wire saw and the cut material.
    • 目的:提供一种驱动皮带轮以及使用该驱动皮带轮的线锯设备和切割方法,使得能够使用线锯的切割装置更加清洁和更轻,并提高其能力。 构成:从驱动滑轮(12)变成的驱动设备安装在由底座支撑的支柱上。 驱动皮带轮由固定轴线上的定子(21)和在定子的外周准备的环形转子(22)和在转子的外周准备的环形滑轮部分(29)组成。 具有环形部分(5a)的金属丝锯(5)在诸如线材等的线材中的烧结金刚石磨料颗粒被布置并缠绕在形成在皮带轮部分的外周边的凹槽(28)中。 卷绕到皮带轮部分的线锯被转子产生的旋转力驱动,通过向驱动皮带轮施加电力,因此线锯通过线锯和切割材料之间的接触来切割材料。

    • PURPOSE: An excavating device is provided to generate high torques by using an attached core bit, thus to easily replace the worn core bit and keep a core from readily fitting into the core bit. CONSTITUTION: The excavating device(1) includes: a cylindrical rotor(32) provided in such a way as to be capable of penetrating a core bit(2); a cylindrical stator(33) provided on the outer periphery of the rotor; fixing parts(34a,34b) provided at both ends of the rotor to fasten the outer peripheral surface of the core bit disposed inside the cylindrical shape of the rotor, to thereby rotate the core bit as the rotor rotates; and a holding bar(4) passed through the cylindrical shape of the core bit to abut on the surface of a core(A) which is the part of concrete(C) inside the core bit.
    • 目的:提供挖掘装置,通过使用附加的钻头头产生高扭矩,从而可以方便地更换磨损的钻头,并保持砂芯容易装入钻头。 构成:挖掘装置(1)包括:以能够穿透芯钻头(2)的方式设置的圆柱形转子(32); 设置在所述转子的外周的圆筒状的定子(33) 设置在转子两端的固定部件(34a,34b),用于固定设置在转子的圆筒形状内的芯钻头的外周面,从而使转子旋转时的芯钻头旋转; 和通过芯钻头的圆筒形状的保持杆(4)邻接在芯钻头内的作为混凝土(C)的一部分的芯(A)的表面上。
