FIG. 2 is a cross-sectional view of a wire saw control apparatus 1000 according to another embodiment of the present invention, FIG. 3 is a view showing the principle of cutting a workpiece O by a wire saw control apparatus 1000 according to an embodiment of the present invention, and FIG. 4 is a view showing a wire saw A wire saw control apparatus 1000 in which a plurality of storage wheels 230 are mounted while the control apparatus 1000 cuts the workpiece O is shown.

A wire saw control apparatus 1000 according to an embodiment of the present invention includes a configuration for cutting a workpiece O by placing a wire saw WS on a workpiece and rotating the wire saw WS at a predetermined speed, to be. In order to cut the wire saw WS, the wire saw control apparatus 1000 includes a plurality of storage wheels 230 for controlling the movement path of the wire saw WS, and as the workpiece O is cut, The saw WS can be pulled in the direction away from the workpiece O, that is, from the workpiece O toward the wire saw control device 1000.

The wire saw control apparatus 1000, which is an embodiment of the present invention for traction of a wire saw WS, may include a main body 100. The main body 100 is a structure for generating a turning force for rotating the wire saw WS and transmitting the generated turning force to the wire saw WS.

The main body 100 of the wire saw control apparatus 1000, which is an embodiment of the present invention, may include a main wheel 110.

The main wheel 110 is a component that rotates the wire saw WS based on the power supplied from the outside, and the shape thereof can be a shape of a handle. 1 and 2 show the main wheel 110 as a disk for convenience, the main wheel 110 may have the shape of a handle, and a wire saw WS such as a disk and a pulley may be mounted, It can be formed into any shape that has a circular shape.

Specifically, the main wheel 110 may be disposed on one side of the main body 110, and may be rotated in a predetermined direction based on the power outside the main wheel 110. 1, the main wheel 110 is disposed on the right side of the wire saw control apparatus 1000, and can rotate the wire saw WS in a clockwise direction. The rotation of the wire saw WS in the clockwise direction is an example only and may be rotated counterclockwise if necessary and the position of the main wheel 110 is also arranged on the left side of the wire saw control apparatus 1000 .

The wire saw control apparatus 1000, which is an embodiment of the present invention, may include a wire storage unit 200.

The wire storage unit 200 is a structure and apparatus for storing wire saws WS that are not in direct contact with the workpiece. The wire storage unit 200 may include at least one of a vertical frame 210 and a horizontal frame 220 and at least one storage wheel 230 may be disposed in each of the frames 210 and 220.

The wire storage unit 200 may include at least one of a vertical frame 210 and a horizontal frame 220. The vertical frame 210 is disposed in front of the main wheel 110 so that the longitudinal direction thereof is perpendicular to the ground And the horizontal frame 220 may be disposed on the upper portion of the main wheel 110 so that the longitudinal direction thereof is parallel to the ground surface. In each of the vertical frame 210 and the horizontal frame 220, the storage wheel 230 may be detached, and a wire saw WS may be mounted on the outer circumferential surface of each of the storage wheels 230.

3 and 4, a vertical frame 210 and a horizontal frame 220 may be disposed on one side of the wire saw control device 1000, respectively, and may be disposed in front of the main wheel 110 At least one vertical wire storage wheel 230a is arranged in the vertical frame 220 and at least a horizontal wire storage wheel 230b is arranged in the horizontal frame 220 disposed on the upper part of the main wheel 110, A wire saw WS may be mounted on the wheel 230.

More specifically, the storage wheel 230 includes a vertical wire storage wheel 230 mounted on a vertical frame 210 to receive a wire saw WS extending from the workpiece O And a horizontal wire storage wheel 230b which is mounted on the horizontal frame 220 and on which the wire saw WS extending from the workpiece is mounted, And a reference wheel 230c that is disposed on the uppermost one of the storage wheels 230 and on which the wire saw WS extending from the workpiece O is mounted. Referring to FIGS. 3 and 4, the reference wheel 230c is shown as being located on the uppermost one of the vertical wire storage wheels 230a. However, the reference wheel 230c is not limited to the horizontal wire storage wheel 230a ), Which is the frontmost one among the plurality of the first and second groups. That is, the reference wheel 230c may be a storage wheel disposed at the front most of the horizontal wire storage wheels 230b, or may be a storage wheel disposed at the top of the vertical wire storage wheels 230a.

The horizontal frame 220 included in the wire saw control apparatus 1000 according to an embodiment of the present invention may have a longitudinal hole 220a along the longitudinal direction and a storage wheel 230 And can be moved along the horizontal frame 220.

1, an elongated hole 220a is formed in the horizontal frame 220 along the longitudinal direction of the horizontal frame 220. The elongated hole 220a is formed in the horizontal frame 220 along the longitudinal direction of the elongated hole 220a. The slide can be moved. As described above, since the wire saw WS can be mounted on the horizontal wire storing wheel 230b, the wire saw WS stored on one side of the body based on the distance between the horizontal wire storing wheel 230b and the reference wheel 230c WS) can be adjusted.

The vertical frame 210 and the horizontal frame 220 included in the wire saw control apparatus 1000 according to another embodiment of the present invention may be formed with a plurality of emboss holes 211 at predetermined intervals along the longitudinal direction , And the storage wheel 230 can be selectively mounted on each of the fixing holes 211 and 221.

Specifically, the vertical frame 210 is formed with a plurality of emboss holes 211 at predetermined intervals in the vertical direction, and each emboss hole 211 may be equipped with a vertical wire storage wheel 230a, A plurality of embossing holes 211 are formed at predetermined intervals in the horizontal direction and a horizontal wire storing wheel 230b may be mounted in each embossing hole 211. [ Since the wire saw WS is mounted on the vertical wire storing wheel 230a and the horizontal wire storing wheel 230b, the number of the storing wheels 230, that is, the vertical wire storing wheel 230a, the horizontal wire storing wheel 230b, The amount of the wire saw WS stored on one side of the wire saw control device 1000 can be determined based on the number of the reference wheels 230c and the reference wheels 230c.

The use of the above-described storage wheel 230 in connection with the driving of the wire saw control apparatus 1000 will be described. As shown in FIGS. 3 and 4, (Workpiece), the wire saw WS may be arranged so as to wrap the beam, and the wire saw WS may be rotated. At this time, in order to cut the beam without damaging the wire saw WS as much as possible, the angle formed between the horizontal wire storing wheel 230b and the beam and reference wheel 230c needs to be minimized. Accordingly, the position of the horizontal wire storage wheel 230b on which the wire saw WS extending from the beam is mounted can be adjusted to form an angle required by the user.

Further, when cutting the workpiece (O) in front of the wire saw (WS), the tension of the wire saw (WS) can be reduced as the cutting progresses. Therefore, as cutting progresses, the wire saw control apparatus 1000 also needs to be moved backward. However, if there is an obstacle behind the wire saw control apparatus WS, the wire saw control apparatus 1000 can not be moved backward. Therefore, if the wire saw WS is not stored separately, Can be reduced. Accordingly, the number of the storage wheels 230 in which the wire saws WS are stored is increased so that the amount of the wire saws WS stored in the storage wheel 230 is increased, ) Can be adjusted.

Hereinafter, a configuration and an apparatus for controlling the tension of the wire saw WS included in the wire saw control apparatus 1000 will be described with reference to FIGS. 5 to 6. FIG.

FIG. 5 is a hydraulic pressure diagram showing a path through which hydraulic oil moves in the wire saw control apparatus 1000 for driving the wire saw control apparatus 1000 according to an embodiment of the present invention. FIG. The electric motor 314 and the hydraulic control valve 312 included in the saw control device 1000 control the hydraulic pressure of the hydraulic oil flowing into the hydraulic cylinder 311. [

The wire saw control apparatus 1000, which is an embodiment of the present invention, may include a tension control unit 300. The tension adjusting unit 300 adjusts the tension of the entire wire saw WS by adjusting the position of the main wheel 110. [

The tension control unit 300 may include a hydraulic cylinder 311, a hydraulic control valve 312, an electric motor 314, and a tension control chain 320.

One side of the hydraulic cylinder 311 is connected to the main wheel 110 so that the position of the mail wheel 110 can be adjusted based on the hydraulic pressure externally applied. Specifically, one side of the hydraulic cylinder 311 may be connected to the main wheel 110, and the other side may be connected to a pipeline through which the hydraulic oil is discharged from the first hydraulic pump 313a. If the hydraulic pressure of the hydraulic oil flowing from the first hydraulic pump 313a is high, the position of the main wheel 110 advances. If the hydraulic pressure of the hydraulic oil is weak, the position of the main wheel 110 is reversed.

At this time, the tension control unit 300 may be provided with a hydraulic control valve 312 for controlling the hydraulic pressure of the hydraulic oil flowing into the hydraulic cylinder 311. The hydraulic control valve 312 may include a driven shaft 312a and a driven shaft pulley 312b projecting outwardly and based on the amount of rotation of the driven shaft pulley 312b, the hydraulic control valve 312 It is possible to restrict the hydraulic pressure of the hydraulic oil entering the hydraulic cylinder 311. The technique by which the hydraulic control valve 312 limits the hydraulic pressure of the hydraulic oil is a well-known technique, and a detailed description thereof will be omitted.

At this time, the inlet is connected to a conduit connected to the hydraulic cylinder 311 from the first hydraulic pump 313a, and the outlet is connected to the hydraulic tank 301. The inlet is moved from the first hydraulic pump 313a to the hydraulic cylinder 311 A part of the operating oil is discharged to the hydraulic tank 301. [0050]

However, the hydraulic control valve 312 requires fine adjustment. That is, as the wire saw WS cuts the workpiece O, the wire saw control apparatus 1000 continuously adjusts the tension of the wire saw WS. To this end, the wire saw control apparatus 1000 It is necessary to adjust the tension of the wire saw (WS) precisely and continuously. For this, the hydraulic control valve 312 needs to be finely adjusted, and further, the driven shaft pulley 312b needs to be slightly rotated little by little.

Accordingly, the electric motor 314 and the hydraulic control valve 312 can be connected to each other by using the tension control chain 320. The electric motor 314 generates power based on an external input so as to rotate the drive shaft 314a projected to the outside of the electric motor 314 and the drive shaft pulley 314b disposed at one side of the drive shaft 314a, The tension adjustment chain 320 may be directly coupled to the drive shaft pulley 314b and the driven shaft pulley 312b. Unlike the electronic hydraulic control system, the hydraulic control system of this type has an advantage that the failure rate is low even in extreme situations, that is, in a state of high dust and humidity.

More specifically, the drive shaft pulley 314b and the driven shaft pulley 312b included in the motor are arranged so that a tension adjustment chain 320 is directly connected to each other. The driven shaft pulley 312b is formed to have a larger size than the drive shaft pulley 314b . At this time, the amount by which the driven shaft 312b is rotated according to the gear ratio of the drive shaft pulley 314b and the driven shaft pulley 312b can be controlled.

For example, assuming that the gear ratios of the drive shaft pulley 314b and the driven shaft pulley 312b are 1: 5, the driven shaft pulley 312b can be rotated one turn only when the drive shaft pulley 314b is rotated five times. By allowing the driven shaft pulley 312b to rotate by a smaller amount than the drive shaft pulley 314b, even if the user rotates the drive shaft pulley 312b by a relatively large amount, the driven shaft pulley 312b can be rotated accurately, The control valve 312 can be controlled more precisely.

Meanwhile, one embodiment of the present invention may include a first hydraulic pump 313a, a second hydraulic pump 313b, and a third hydraulic pump 313c. Each of the hydraulic pumps 313a, 313b and 313c is configured to receive hydraulic oil from the hydraulic tank 301 and transfer the hydraulic oil to the hydraulic cylinder 311 or the hydraulic motors 321 and 331. One side of the first hydraulic pump 313a, the second hydraulic pump 313b and the third hydraulic pump 313c can be connected to the hydraulic tank 301 by a pipeline. 313 may be connected to the hydraulic pump 301, or a different hydraulic tank 301 may be connected to each of the hydraulic pumps 313.

Specifically, the first hydraulic pump 313a has one side connected to the hydraulic tank 301 through a channel, and the other side connected to the hydraulic cylinder 311 through a pipeline to supply the hydraulic fluid to the hydraulic cylinder 311, One end of the pump 313b is connected to the hydraulic tank 301 through a channel and the other end of the pump 313b is connected to the one hydraulic motor 321 to supply hydraulic oil to the one hydraulic motor 321. The left endless track 331 The third hydraulic pump 313c is connected to the hydraulic tank 301 through a duct and the other is connected to the second hydraulic motor 322 through a duct and supplies hydraulic oil to the second hydraulic motor 322 The right endless track 332 can be rotated.

The wire saw control device 1000 may be driven on a non-flat surface, and the torque applied to each of the endless tracks 331 and 332 may have to be different from each other. Therefore, the hydraulic pumps 313b and 313c for supplying the hydraulic oil to the hydraulic motors 321 and 322 connected to the respective endless tracks 331 and 332, respectively, can be disposed. In the case of driving the main wheel 110 and the respective infinite trajectories 331 and 332 with one hydraulic pump, either one of the respective components fails or the hydraulic pump 313 for supplying the hydraulic oil to the corresponding component If it fails, all configurations in the wire saw control device 1000 may not work. Thus, the wire saw control apparatus 1000, which is an embodiment of the present invention, allows the three pumps 313 to supply the operating fluid, respectively, so that even if any one of the configurations contained in the wire saw control apparatus 1000 fails The remaining configuration can be continuously driven.

One embodiment of the present invention may include a left endless track 331 and a right endless track 332. The left endless track 331 and the right endless track 332 are configured to move the wire saw control device 1000.

The left endless track 331 is disposed on one side of the lower portion of the main body and is formed in the form of an endless track. The right endless track 332 is disposed on the other side of the lower portion of the main body and is formed in the form of an endless track. Can rotate based on the external power. The wire saw control device (1000) mainly works in a place where the ground condition is uneven, such as a construction site and a mine. Accordingly, each of the endless tracks 331 and 332 included in the wire saw control device 1000 is formed in the form of an endless track, so that it can easily rotate on any topography.

Meanwhile, the wire saw control apparatus 1000, which is an embodiment of the present invention, may include a wire angle adjusting unit 400. The wire angle adjusting unit 400 is a configuration for adjusting the angle at which the wire saw WS extends toward the workpiece O.

First, the wire angle adjusting part 400 may include a turning rail 410 and an angle adjusting frame 420. The pivotal rail 410 is pivotably hinged to the main body 100 to adjust the angle with respect to the main body and guide the movement path of the slide rail 430 so that the slide rail 430 to be described later can be raised or lowered And the angle adjusting frame 420 ascends or descends along the slide rail 430 to determine the height of the wire saw WS to be held on the workpiece O and adjusts the moving direction of the wire saw WS .

The pivotal rail 410 may be disposed on one surface of the wire saw control device 1000 facing the workpiece O with one end in the longitudinal direction facing the ground surface. Specifically, the longitudinal end surface of the pivotal rail 410 may be formed in the shape of a rail and disposed on the front surface of the wire saw control device 1000. (Not shown) protruding outward perpendicularly to the side surface of the pivotal rail 410 are formed at both widthwise ends of both sides of the pivotal rail 410. Slides of a slide rail 430 The step 430a can be movably coupled up and down.

The angle adjusting frame 420 is hinged to a carrier 440 to be described later, and at least one guide pulley 501 may be included. The angle of the wire saw WS attached to one side of the carrier 440 may be changed along with the angle formed by the angle adjusting frame 420 with the carrier 440. The angle regulating frame 420 may be formed in a hexahedral shape, but this is merely an example, and the angle regulating frame 420 may have any structure as long as the carrier 440 to be described later can be hinged.

Meanwhile, the wire saw control apparatus 1000, which is an embodiment of the present invention, may include a wire direction switching unit 500.

The wire direction switching unit 500 may include a plurality of guide pulleys 501, 502, and 503. The wire saw WS is mounted on the outer circumferential surface of the guide pulleys 501, 502 and 503 so that the wire saw WS is guided by the guide pulleys 501 502, and 503, the direction of movement of the wire saw WS is changed in a direction perpendicular to the rotation axis of the guide pulleys 501, 502, and 503.

The guide pulleys 501, 502, and 503 may include at least one side guide pulley 501. The side guide pulley 501 is coupled to a side surface of the carrier, and the rotation axis may be formed parallel to the rotation axis of the main wheel 110. Each of the side guide pulleys 501 moves the moving direction of the wire saw WS moving from the side guide pulley 510 toward the main wheel 110 and the wire storage wheel 230 from the workpiece O (WS) moving toward the side guide pulley (501).

The side guide pulley 501 may include a first side guide pulley 501a and a second side guide pulley 501b. The wire saw WS may be mounted on each of the side guide pulleys 501a and 501b , The wire saw WS entering the respective side guide pulleys 501a and 501b and the wire saw WS being discharged are formed perpendicular to each other.

At this time, the wire saws WS mounted on the respective side guide pulleys 501 have different traveling directions depending on the direction in which the main wheel 110 rotates. 1, a first side guide pulley 501a is provided at a relatively long distance relative to the pivotal rail 410 on one side of the carrier 440, When the wire saw WS mounted on the outer circumferential surface of the first side guide pulley 501a moves toward the workpiece O, the guide pulley 501b is mounted on the outer circumferential surface of the second side guide pulley 501b. The wire saw WS moves toward the mail wheel 110 and moves to the workpiece O when the wire saw WS mounted on the outer peripheral surface of the second side guide pulley 501b moves toward the workpiece O. [ The wire saw WS mounted on the outer peripheral surface of the first side guide pulley 501a moves toward the mail wheel 110. [

The guide pulleys 501, 502 and 503 may include at least one upper surface guide pulley 502. The upper surface guide pulley 502 is coupled to the upper surface of the carrier 440 and the rotation axis may be formed perpendicular to the upper surface of the carrier 440. Each of the upper surface guide pulleys 502 guides the moving direction of the wire saw WS moving from the upper surface guide pulleys 502a and 502b toward the main wheel 110 and the wire storage wheel 230, (WS) moving toward the upper surface guide pulley (502). 1 and 2, the upper surface guide pulley 502 may include a first upper surface guide pulley 502a and a second upper surface guide pulley 502b. In each upper surface guide pulley 502, And the wire saw WS and the wire saw WS which enter the respective upper surface guide pulleys 502 are formed perpendicular to each other.

Meanwhile, at least one bottom guide pulley 503 may be included in the guide pulleys 501, 502, and 503. The bottom guide pulley 503 is coupled to the bottom surface of the carrier 440 and the rotation axis may be formed perpendicular to the bottom surface of the carrier 440. Each of the bottom guide pulleys 503 guides the moving direction of the wire saw WS moving from the bottom guiding pulley 503 toward the workpiece O from the side guiding pulley 501 toward the bottom guiding pulley 503 And can be formed to be perpendicular to the moving direction of the moving wire saw WS. 7 to 9, the bottom guide pulley 503 may include a first bottom guide pulley 503a and a second bottom guide pulley 503b. In each bottom guide pulley 503, a wire saw WS, and the wire saw WS and the wire saw WS which enter the respective bottom guide pulleys 503 are formed perpendicular to each other.

At this time, the wire saws WS mounted on the respective bottom guide pulleys 503 have different traveling directions depending on the direction in which the main wheel 110 rotates. 7, the first bottom guide pulley 503a is relatively distant from the pivoting rail 410 in the bottom surface of the carrier 440, and the first bottom guide pulley 503a is relatively far from the pivoting rail 410, When the wire saw WS mounted on the outer circumferential surface of the first bottom surface guide pulley 503a moves toward the workpiece O, the pulley 503b is placed on the outer circumferential surface of the second bottom surface guide pulley 503b.

The longitudinal end surface of the slide rail 430 may have the shape of a rail. Slide steps 430a extending outward perpendicularly to the side surfaces of the slide rails 430 are formed at both widthwise ends of both side surfaces of the slide rail 430. Between the slide steps 430a, A step (not shown) is coupled, and the slide rail 430 can be moved along the rotation step.

The wire saw control device 1000 may include height adjustment cylinders 601 and 602 to transmit power to the slide rail 430 so that the slide rail 430 moves along the pivot rail 410. The height adjusting cylinder 601 is coupled to the lower portion of the slide rail 430 at one end in the longitudinal direction and coupled to the main body 100 at the other end. As shown in FIG. Although the height adjustment cylinders 601 and 602 are illustrated as being configured to adjust the height of the slide rail 430 in the present invention, any structure capable of adjusting the height of the slide rail 430 in addition to the height adjustment cylinders 601 and 602 is also applicable .
