すると共に、粉塵の発生を抑制するためのものである。A conventional wire saw uses a diamond wire 1 as shown in FIG. 2, which is a steel wire 10 with diamond beads 11 attached at predetermined intervals. As shown in FIG. 5, when the object 8 to be cut is a stone pillar, concrete pillar, etc., the motorized drive pulley 12 can be moved away from the object 8 along the rail 15 on the base 14. The apparatus main body 22 is installed as shown in FIG. At the same time, it was placed under tension on the drive pulley 12 via a plurality of small pulleys 13. Then, by rotating the drive pulley 12, the diamond wire 1 was slid onto the outer peripheral surface of the object 8 to be cut. At this time, in order to keep the diamond wire 1 under tension, the drive pulley 12 is moved to the rail 1 as the cutting operation progresses.
5, the object gradually moves away from the object 8. Note that the reference numeral 16 in the figure indicates a water injection nozzle, which is used to protect the diamond beads 11 by injection of water during cutting and to suppress the generation of dust.

少なく、鋸歯を備えた解体用切断機器、例えば丸鋸では
切断不可能であった大断面の対象物も容易且つ効率良く
切断し得るという特徴を有していた。This conventional wire saw generates less vibration, noise, and dust, and has the advantage of being able to easily and efficiently cut large cross-section objects that could not be cut with demolition cutting equipment equipped with saw teeth, such as circular saws. It had

で、作業が面倒であるのに加え、継目部分に充分な接合
強度を得難いという欠点があった。However, with the above-mentioned wire saw, it is necessary to cut the diamond wire to a predetermined length according to the object at the work site, and then connect the two ends to make an endless shape. The drawback was that it was difficult to obtain sufficient bonding strength at the joint.
そのため、切削作業時にダイ、ヤモンドワイヤーが対象
物に何度も繰返し摺動し且つ彎曲するうちに、継目部分
でしばしば切断してしまうという問題点もあった。Therefore, there is a problem in that during cutting work, the die and the diamond wire repeatedly slide and curve against the object and often break at the joints.

張るという欠点があった。In addition, in the conventional method, in order to maintain the tension of the diamond wire during cutting, the motorized drive pulley is moved along the rail on the base in a direction away from the object. The disadvantage was that the larger the cross-sectional area (the larger the distance, the longer the base needed to move) and the higher the height of the device itself.
加えて、対象物が変わる都度、装置本体をそのレールが
対象物から離れる方向へ伸びるように配置し直さねばな

せ、作業能率向上を妨げる大きな要因となっていた。In addition, each time the target object changes, the main body of the device must be rearranged so that the rails extend away from the target object, which, together with the complexity of arranging and joining the diamond wires, is a major factor hindering improvements in work efficiency. It became.

態で正逆方向に繰返し巻取り又は送り出すものである。The central control panel 3 is separately installed on the trolley 21, and is connected to the control sections 7, 7 of both winding units 2, 2, and both drive devices 6.
, 6 are operated in conjunction with each other, and winding and feeding are repeated alternately while a constant tension is applied to the diamond wire 1 between both drums 5 and 5. Specifically, the drive device 6 on the sending side is operated in a constant speed operation mode and the drive device 6 on the winding side is operated in a constant torque operation mode, or conversely, the drive device 6 on the sending side is operated in a constant torque operation mode and the winding side is operated in a constant torque operation mode. By operating in the fast running mode, the diamond wire 1 is wound with constant tension from one notram 5 to the other drum 5. For example, if the diamond wire 1 that was being sent out from the drum 5 on the left in FIG. , 6, change the rotation direction and operation mode of both drums 5, 5, and rewind the diamond wire 1 from the right drum 5 to the left drum 5 with a constant tension.
When the wound diamond wire 1 is running low, the rotational direction and operation mode of the drive devices 6, 6 are changed again, and the diamond wire 1 is fed out from the left drum 5 and wound up by the right drum 5. In this way, both winding units 2 are controlled by the centralized control panel 3.
, 2 work together to repeatedly wind up or send out the diamond wire 1 in a tensioned state between the two drums 5, 5 in the forward and reverse directions until the cutting of the object 8 is completed.

ンドワイヤー１の巻取方向の反転を繰返す。In order to cut an object 8 such as a stone pillar using the wire saw described above, first, the winding units 2, 2 are arranged and fixed at appropriate positions that substantially sandwich the object 8. Pull out one end of the diamond wire 1 that is completely wound around the drum 5 of one winding unit 2, bring it into contact with the part of the object 8 that is to be cut, and then attach it to the drum 5 of the other winding unit 2. to lock. At this time, an idle roller 9 is disposed as necessary so that the diamond wire 1 can curve smoothly and come into close contact with the object 8. A water nozzle 16 is attached to a location where the diamond wire 1 and the object 8 come into contact. A central control panel 3 is placed at an appropriate position and electrically connected to both winding units 2, 2. Once all preparations are complete, turn on the central control panel 3, and both take-up units 2 and
2 to operate in conjunction. Then, the diamond wire 1 sent out from one drum 5 slides and cuts the circumferential surface of the object 8 while being subjected to a constant tension, and is then wound onto the other drum 5. When the remaining amount of the diamond wire 1 wound on the former drum 5 is small (when the both drums 5, 5 are reversed, the diamond wire 1 is wound from the latter drum 5 to the former drum 5 with a constant tension). The reversal of the winding direction of the diamond wire 1 is repeated until the cutting of the object 8 is completed.

する。In addition, during the above-mentioned cutting operation, cutting water is sprayed from the water injection nozzle 16 before the diamond wire 1 comes into contact with the object 8, in order to prolong the service life of the diamond wire 1 and to prevent the generation of dust. There is. In the present invention, since the sliding direction of the diamond wire 1 is reversed, the water injection nozzle 16 is installed at three locations, and in conjunction with the reversal of the drum 5, the water injection nozzle is always located before the diamond wire 1 starts contacting the object 8. Water will be poured from 16 onwards.

Wind almost all of the diamond wire 1 around one drum 5, remove the tip of the diamond wire 1 from the other drum 5, place or add idle rollers 9 as needed, and rewind the diamond wire 1. It is wound around the object 8 for less than one turn, and is again latched to the latter (other) drum 5, the water injection nozzle 16 is attached, and the cutting operation is then carried out in the same manner as described above. Here, the idle roller 9 is connected to the drum 5 without any trouble by the diamond wire 1.
It is arranged to be wound around the object 8 or to be fed out without excessive bending (so that it can be wound around the object 8, and to slide over the area where the object 8 is to be cut. This is not necessarily necessary depending on the positional relationship between the object 8 and both winding units 2, 2, the size of the object, etc.

る。The wire saw of the present invention and its method of use include a pair of winding units that alternately feed and wind a long diamond wire with a constant tension while contacting an object, and both winding units are linked together. It consists of a centralized control panel for operation, and each can be distributed and used, so it does not need to be as expensive as conventional equipment, and does not necessarily require a large space at the work site, so it can be used in narrow spaces. Even in crowded places, cutting work on pillars, walls, etc. can be carried out without any hindrance.

Work efficiency is improved, and there is no risk of work delays due to breakage of joints.
