Included.

In detail, rollers 85a and 85b are rotatably coupled to the vertical movement members 83a and 83b. In addition, a part of the wire 15 is enclosed below the central axis of the rollers 85a and 85b. The vertically movable members 83a and 83b are vertically moved along the guide members 82a and 82b according to the size of the tension of the wire 15. In addition, the detectors 90a and 90b detect the sensor recognizers 84a and 84b extending from the vertical movement members 83a and 83b.

The sensing units 90a and 90b include a plurality of sensors that are spaced apart from each other by a predetermined interval up and down. In addition, a sensor for detecting the sensor recognizers 84a and 84b at a position where the optimum tension of the wire 15 is maintained among the plurality of sensors is set as the reference sensors 91a and 91b.

The rotation speed of the third driving unit 55 for rotating the reel members 51 and 52 is varied according to the position of the sensor that senses the sensor recognition units 84a and 84b. At this time, it is noted that the position information of the sensor is stored in a memory unit (not shown).

The operation of the tension sensing device and the tension maintenance process of the wire 15 will be described.

As an example, the case where the wire 15 is unwound by the first reel member 51 and the wire 15 is wound by the second reel member 52 will be described.

When the first reel member 51 is rotated at a constant speed and the wire 15 is released, the vertical movement member 80a on the side of the first reel member 51 gradually moves upward from the reference position. Hereinafter, the vertical movement member on the side of the first reel member is referred to as a first vertical movement member.

That is, when the wire 15 is released in a state in which the first reel member 51 is rotated at a constant speed, the first reel member 51 during one rotation of the first reel member 51 as time passes. ) The length of the wire 15 is reduced. As a result, the tension of the wire 15 gradually increases, and the first vertical movement member 83a moves upward. Then, the sensor recognition unit 84a is detected by the sensor 92a located above the reference sensor 91a. In this case, it is determined by the controller (not shown) that the tension of the wire 15 is larger than the reference. Then, the control unit controls to increase the rotation speed of the third drive unit 55 for rotating the first reel member 51.

In addition, when the rotational speed of the third driver 55 is increased, the tension of the wire 15 is reduced, so that the first vertical movement member 83a moves downward. In addition, an appropriate tension of the wire 15 may be maintained while the first vertical movement member 83a moves downward.

At this time, the wire 15 unwound by the first reel member 51 is wound around the second reel member 52.

Upon initial operation of the rock cutting device 1, the second reel member 52 is set to rotate at the same speed as the first reel member 51. Then, since the length of the wire 15 wound on the second reel member 52 is smaller than the length of the wire 15 released from the first reel member 51 in one rotation, the second reel member ( The up-down moving member 53b on the 52) side moves downward from the reference position. Hereinafter, the vertical movement member on the side of the second reel member is referred to as a second vertical movement member.

Then, the sensor recognition unit 84b is detected by the sensor 93b positioned below the reference sensor 91b. Then, the control unit controls to increase the rotational speed of the third drive unit 55 for rotating the second reel member 52. In addition, when the rotational speed of the third ball eastern part 55 is increased, the tension of the wire 15 is reduced, so that the first vertical movement member 83b moves downward.

In addition, an appropriate tension of the wire 15 may be maintained while the first vertical movement member 83b moves downward.

When the wire 15 is continuously wound on the second reel member 52, the length of the wire 15 that is wound during one rotation of the second reel member 15 becomes longer than the initial stage. Then, the sensor recognizing unit 84b is detected by the sensor 92b located above the reference sensor 91b.

Then, the control unit controls to increase the rotational speed of the third drive unit 55 for rotating the second reel member 52. When the rotational speed of the third driving unit 55 is increased, the tension of the wire 15 is increased, so that the first vertical movement member 83b is moved upward. In addition, an appropriate tension of the wire 15 may be maintained while the first vertical movement member 83b moves upward.

According to the present embodiment as described above, the tension of the wire 15 is sensed by the pair of tension sensing devices 80a and 80b, and accordingly, the third driving unit for driving the respective reel members 51 and 52 ( The rotational speed of 55 is individually adjusted so that the tension of the wire 15 can be properly maintained.

Hereinafter, the overall operation of the rock cutting device will be described.

An example of the process of unwinding the wire 15 from the first reel member 15 and of winding the wire 15 from the second reel member 52 will be described.

When the rock cutting device 1 is operated, the first reel member 51 is rotated in one direction, and the second reel member 52 is rotated in the other direction. At the same time, the plurality of rollers 11, 12, 13, 14 are rotated in the same direction. Then, the wire 15 released from the first reel member 51 is moved by the rotation of the rollers 11, 12, 13, 14 to be wound around the second reel member 52.

The support device 30 is moved upward. In addition, the rock 5 is cut into a plurality of portions while passing the cutting region 15a of the wire 15 while the supporting device 30 is moved upward. In the process of cutting the rock 5, the slurry is supplied from the slurry supply unit 16. And, when the rock 5 is cut completely, the support device 30 is moved downward. According to this embodiment, since the rock is cut by the wire 15 surrounded by a plurality of rollers (11, 12, 13, 14), the thickness of the cut rock can be thin, the fast time The rock 5 can be cut.

On the other hand, when the fixed amount of the wire 15 is released from the first reel member 51, the first reel member 51 and the second reel member is changed in the reverse direction. Then, the wire is wound around the first reel member 51, and the wire wound around the second reel member 52 is released. At this time, the rotation direction change of each reel member (51, 52) may be determined based on the rotational speed of any one reel member. For example, when the rotational speed of the reel member on the side where the wire 15 is released becomes a certain speed or more, the rotational direction of the reel member can be reversed.
