Description

Rock excavation monitoring system {BASE ROCK EXCAVATION MONITING SYSTEM}

The present invention relates to a bedrock excavation monitoring system capable of efficiently dividing and crushing the rock to be excavated while easily loading the disintegrated rock as well as monitoring a series of processes.

In general, excavators widely used in construction work sites are designed to diversify the uses of excavators by installing various optional attachments including a unique bucket installed in the excavator according to the purchaser's purchase. , This optional working machine is to be mounted on the arm at the tip of the excavator by means of a fastening pin and fast hole clamp.

In addition, the rock excavation method mainly consists of the blasting method and the mechanical drilling using a power breaker.

At this time, in the case of the blasting method, very loud noise and vibration, as well as dust, etc. are caused, so it is not used especially in downtown areas except for special cases.

The excavation method commonly used in downtown areas is the power breaker method, which is used to break up the excavated rock by attaching a hydraulic breaker to the excavator and crushing the rock by hitting the chisel on the excavation surface.

This method also has a problem in that it is unsuitable for long-term work in urban areas because noise and shock vibration are relatively large, causing civil complaints.

In addition, conventional rock excavation methods have problems such as inefficiency of work by performing drilling of the rock, gradation and loading with different equipment, and impossible to perform gradation work if there is no free surface.

In addition, in the conventional rock excavation methods, since the drilling and gradation of the rock are performed within the ground, a series of processes cannot be confirmed, so the operator has to visually check each process with the naked eye and then proceed to the subsequent process.

That is, the high-pressure water required in the drilling process of the drilling part 20 can be utilized in the step-by-step process of the rock-cutting part 30 of the present invention. The equipment can be operated economically and efficiently because no equipment is required.

As an example, the granite part 30 may have a wedge structure and move according to the supply of high-pressure water, and may gradually expand in appearance in the granite space 200 , and may break the rock adjacent thereto.

To explain this in detail, as shown in FIG. 5 , the arm part 30 is configured to include a flow module 310 whose external appearance is expanded and an expansion module 300 for expanding the flow module 310 . can

The flow module 310 has an internal space 311 corresponding to the shape of the expansion module 300 and can accommodate the expansion module 300 descending toward the internal space 311 .

In addition, the flow module 310 may be composed of a plurality of unit modules 312 divided by forming a plurality of cutouts in a vertical direction.

In this embodiment, an example in which the two unit modules 312 are symmetrically divided because the incision portion is configured as a pair is presented, but the number of unit modules 312 divided according to the incision portion and the incision portion is arbitrary. setting is possible.

Here, the flow module 310 is not limited in its shape, but may preferably be configured in a hexahedral shape having one or more side surfaces rather than a cylindrical shape.

The flow module 310 may be spaced apart from each other by a lateral distance between the unit modules 312 according to the insertion depth of the expansion module 300 inserted into the inner space 311, and the expansion of the flow module 310 It is possible to divide or crush the rock in the rock-cut space 200 by the .

That is, according to the structure of the arm part 30 according to the present embodiment, the outer surface of the expansion module 300 and the inner surface of the flow module 310 have a tapered shape having the same inclination to each other. When the expansion module 300 is inserted exceeding a set critical depth while descending and being inserted into the internal space 311 of the flow module 310, the unit modules 312 of the flow module 310 are It can be extended to be gradually spaced apart from each other in the outward direction around the incision, and by this expansion, the side of the adjacent rock is pressed to perform the granite process.

At this time, in the present invention, an example of using high-pressure water used as a driving source of the perforation part 20 as a driving source for providing a lift drive for the flow module 310 is provided, and the perforation part ( 30) may include a cylinder casing 320 and a piston 330 as shown in FIG.

The cylinder casing 320 has an elevating space 321 inside which the piston 330 and the expansion module 300 can elevate, and the lower part has an opening 322 through which the expansion module 300 can pass. is formed

The cylinder casing 320 is provided with an inlet/outlet 323 that communicates with the elevating space 321 so that high-pressure water can be introduced and discharged, so that the introduced high-pressure water acts as a pressure in the elevating space 321 . .

The piston 330 is lifted and driven in the vertical direction by the hydraulic pressure acting in the lifting space 321 of the cylinder casing 320 , that is, the pressure by the high-pressure water.

Although not shown in the drawings, the piston 330 is equipped with a piston ring having a tapered outer circumferential shape or a convex structure around the circumference coming into contact with the inner surface of the cylinder casing 320, so that the inner surface of the cylinder casing 320 and the line Make sure to maintain airtightness even when lifting and lowering while making contact.

And referring to FIG. 5 , the upper end of the expansion module 310 is coupled to the bottom surface of the piston 330 so that the piston 330 and the expansion module 310 are integrally interlocked. According to the lift driving, the expansion module 310 may be drawn out from the elevating space 321 in a lower direction through the opening 322 of the cylinder casing 310 or may be introduced in an upper direction toward the elevating space 321 .

At this time, the flow module 310 has a larger engaging rim 313 than the diameter of the opening 321 is formed along the rim of the upper end, and the upper end on which the engaging rim 313 is formed is elevating the cylinder casing 320 . It is positioned in the space 321 to allow movement in the lateral direction, thereby preventing the flow module 310 from being separated and guiding it so that the movement can be made stably.

On the other hand, the arm unit 10 of the present invention may be provided with a supply means for supplying high-pressure water to the perforation unit 20 and the arm unit 30 from an external water pump, first the cylinder casing 320 . and a first water pipe 40 passing through the center of the piston 330 and the flow module 310 and communicating with the perforation 20 .

In addition to this, the halberd device 10 includes a second water pipe 60 and the first water pipe 40 and the second water pipe 60 connected to the inlet/outlet 323 of the cylinder casing 320 . It may include a high-pressure water control valve 70 that is connected and controls the supply of high-pressure water to either the first water pipe 40 or the second water pipe 60 according to an input of a control signal.

That is, in the halberd apparatus 10 of the present invention, the high-pressure water control valve 70 is controlled so that high-pressure water is supplied only through the first water pipe 40 while blocking the high-pressure water supply of the second water pipe 60 during the drilling process. In the stepping process, the high-pressure water control valve 70 is controlled so that the high-pressure water is supplied or recovered only through the second water pipe 60 while blocking the high-pressure water supply of the first water pipe 40 on the contrary.

At this time, although not shown in the drawings in the present invention, a control unit for controlling the water pump and the high-pressure water control valve 70 may be further included. The pressure of the water pump is controlled so that the piston 330 can repeat the ascending and descending of the intersection in the lifting space 321 of the cylinder casing 320 to control the pressure of the water pump in the perforated granite space 200. By applying repeated pressurization and impact by the

Hereinafter, the structure of the perforation portion 20 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4 .

As mentioned above, the perforation 20 is connected to the front of the granite part 30 to be spaced apart from each other, and the granite space 200 is formed by drilling the rock to be excavated to a certain depth.

Such a perforation part 20 may be variously implemented by applying a known technique, but in this embodiment, a water jet principle configured to spray high-pressure water is applied to minimize vibration and noise that may occur during perforation. configured to do so.

The perforation part 20 is operated by high-pressure water supplied through the first water pipe 40 to perforate the rock through high-speed rotation. As shown in FIGS. 2 to 4 , the water jet housing 210 ) and a pair of waterjet nozzles 220 provided in front of the waterjet housing 210 and a plurality of drill bits 230 configured in front of the waternet housing 210 .

The waterjet housing 210 includes a front flow path 240 formed on a front diameter line, and a side flow path 250 connected to the front flow path 240 and formed on a side surface of the waterjet housing 210, a pair of The water jet nozzles 220 of the water jet housing 210 are spaced at equal intervals on both sides of the center of the water jet housing 210 and are provided on the front flow path 240 .

The front flow path 240 and the side flow path 250 are used as discharge passages for discharging rock powder generated during the drilling operation to the outside, and although not shown in the drawings, may be configured to communicate with a discharge line flowing in from the outside. , Preferably, the first water pipe 40 is configured in the form of a double pipe so that it can be discharged through the double pipe of the first water pipe 40 .

The pair of waterjet nozzles 220 inject high-pressure water in alternating directions, so that the rock is perforated by the high-pressure water and the perforation 20 is rotationally driven by the reaction force of the high-pressure water at the same time. The unperforated rock is perforated by the drill bit 230 .

Therefore, the jetting direction of the waterjet nozzle 220 is inclined at a predetermined angle with the plane passing through the central axis of the perforation portion 20, and the jetting direction is 20 to 70 degrees in the direction parallel to the central axis of the waterjet housing 210, preferably Preferably, the inclination is 30 to 60 degrees, most preferably 40 to 50 degrees.

That is, the bedrock is perforated by the high-pressure water sprayed in alternating directions from the pair of waterjet nozzles 220, and the perforation unit 20 is rotated by the reaction force of the high-pressure water. The unperforated rock is perforated (crushed) by the formed drill bit 230 .

Here, if the angle of the jetting direction of the pair of waterjet nozzles 220 is increased, the rotation of the perforation part 20 is good, but the drilling direction is too outward, and if the angle of the jetting direction is small, the rotation of the perforation part 20 is good. Since the rotation is not smooth and the drilling is disadvantageous by the drill bit 230, it is preferable to select the angle of the injection direction within the range limited above.

In addition, a water jet line for supplying high-pressure water to the pair of water jet nozzles 220 may be provided. This water jet line is not shown in the drawings, but the first water pipe passing through the arm part 30 . By being introduced into the perforation portion 20 through 40 , it may communicate with the waterjet nozzle 220 .

The perforation part 20 may be screw-coupled at the front end of the arm part 30, and a rotation shaft 260 having a flow path communicating with the waterjet line in the center, and a rotation shaft 260 provided in front of the high-pressure water A bush 270 for preventing water leakage and a bearing 280 provided on the circumferential side of the rotating shaft 260 to enable independent rotation at the front end of the arm portion 30 to prevent high-pressure water leakage and at the same time Allows for smooth rotation.

In this case, the high-pressure water used in the drilling process by the drilling part 20 may be supplied from an ultra-high pressure water power pack (UHP<Ultra High Pressure water jet> power pack).

The ultra-high pressure water power pack is connected to the water jet line so that the high pressure water is supplied and sprayed to the perforation part 20 .

For example, the UHP power pack that generates high-pressure water can generate a high pressure of 3,000 bar or more and a flow rate of 30 l/min or more, and a flow rate of 6-7 l/min is applied to each perforation 20. It is good to supply.

At this time, the high-pressure water is supplied to the drilling part 20 to set the pressure of the high-pressure water used for the rock-cutting work to about 1,500 bar, so that the drilling and the rock-cutting work are possible with the ultra-high pressure water power pack without a separate hydraulic device.

In addition, the perforated portion 20 has a structure in which a water jet nozzle 220 is formed at an end thereof, and a repulsive force is applied by high-pressure water of about 8 kgf sprayed in opposite directions during high-pressure injection, and by this repulsive force, the rotating shaft 260 ), the rotational force is generated.

And the bush 270 formed on the rotating shaft 260 prevents leakage of high-pressure water, the bearing 280 provides a structure for smooth rotation, and the number of nozzles is two when drilling the rock through the waterjet nozzle 220 . However, the drilling part 20 is rotated by the water jet nozzle 220 and the entire area is drilled without omission, thereby forming a circular granite space 200 .

In particular, the drill bit 230 interlocking according to the high-pressure water injection rotates to strike and pulverize the protruding part that is not perforated by the high-pressure water, so that the drilling speed of waterjet drilling using mechanical drilling is increased compared to pure waterjet.

That is, the drilling speed of the drilling part 20 is generally about 500mm/min based on Φ60mm, this speed is smaller than the hydraulic crawler drill drilling speed, but higher than the pneumatic drilling machine, and also a rotary core generally used for rock granite. This is much faster than the drill's 50mm/min.

In general, the reason for using a core drill, which has a lower speed than a hydraulic crawler drill, which has a fast drilling speed, is that it is convenient to insert the split arm part 30 when the drilling diameter is smoothly drilled, and it is possible to make a smooth break arm because it adheres well to the split arm. First, the drilling part 20 uses a waterjet rotating at a high speed, unlike a general crawler drill, it minimizes the disturbance of the bedrock by the blow, so it is possible to secure a smooth shape of the drilling. Unlike the general method of granite, it performs the granite at the same time as the drilling, so the state of the drilling diameter has little effect on the granite process, and it enables very efficient granite work compared to the general granite method.

The perforated debris (debris) may be discharged to the outside through a discharge line separately installed in the perforated portion 20 to the granite portion 30 and the like. In general, crawler drills discharge the perforated rock powder to the outside using high-pressure air, but unlike the crawler drill drilling depth of several to tens of m, the present invention has a very short hole diameter of 500 mm, so smooth discharge is possible without the use of high-pressure air. And because the high-pressure water jet is sprayed, the rock particles can be easily discharged together with the discharged water.

In the above, the drilling part 20 has been described as an example of a water jet structure using high-pressure water, but the present invention is not limited thereto, and it is natural that various well-known drilling methods such as a hydraulic type can be applied.

Hereinafter, an operating state of the halam device 10 of the present invention will be described with reference to FIGS. 6a to 6e.

As shown in Fig. 6a, after positioning the rock rock device 10 on the rock 1 to be excavated, the rock rock device 10 is lowered so that the perforation portion 20 faces the ground.

And as shown in FIGS. 5B and 5C, first, the high-pressure water control valve 70 is controlled so that the high-pressure water is supplied to the drilling part 20 through the first water pipe 40, so that the drilling part 20 Gradually lowering the rock-cutting device 10 to a preset depth while operating, the drilling process is performed to the planned depth through rotational driving of the drilling part 20 .

After that, when the drilling process by the drilling part 20 is completed to the planned depth and the rock-cutting space 200 is secured, the high-pressure water supply of the first supply pipe 40 is stopped while the position of the rock-cutting device 10 is fixed. to stop the operation of the perforation part 20 and at the same time control the high-pressure water control valve 70 to raise and lower the cylinder casing 320 with high-pressure water supplied from the water pump through the second water pipe 60 . By supplying to the space 321, the pressure by the high-pressure water acts in the lifting space 321, and the piston 330 and the expansion module 300 connected to the piston 330 by this pressure are connected to the cylinder casing 320. to be withdrawn downward through the opening 322 of the

As shown in FIG. 6D, a part of the extended module 300 withdrawn is inserted into the internal space 311 of the flow module 310. At this time, if the supply amount of high-pressure water is controlled by controlling the water pump, the expansion module ( Since the insertion depth of 300) can be adjusted, the critical depth set by gradually lowering the expansion module 300 during the halam process, that is, the depth at which the outer surface of the expansion module 300 and the inner surface of the flow module 310 come into contact with each other. Apply pressure to the lifting space 321 to exceed.

When the expansion module 300 is inserted so as to exceed a set critical depth, the unit modules 312 of the flow module 310 are spaced apart from each other in the outward direction around the incision site and expand, and by this expansion, By pressing the side, it is possible to subdivide the rock (1) to be subdivided.

At this time, as described above, by repeatedly raising and lowering the position of the expansion module 300 to apply repeated pressurization and impact by the rock block part 30 in the rock rock space 200, the rock rock process is performed. It can be done more easily and efficiently.

Then, when the halm process is completed, the high-pressure water supplied to the elevating space 321 of the cylinder casing 320 is recovered through the inlet/outlet 323, and the piston 330 and the expansion module connected to the piston 330 ( 300) is raised and the flow module 310 is returned to its original state, and then the rock rock device 10 is raised to separate it from the perforated rock rock space 200 .

On the other hand, the monitoring device 50 may be connected to the armpit device 10 from a remote location through a communication network, and the perforation unit 20 and the arm unit 30 each state information is collected and performed in the arm unit 10 . A series of rock excavation conditions can be monitored in real time.

Here, the state information includes event data including driving information and error information output from the perforation unit 20 and the arm unit 30 itself of the arm unit 10, as well as motion information for each device detected by the sensor. can

In addition, the communication network referred to in the present invention is an IP network that provides a large-capacity data transmission/reception service and a data service without interruption through Internet Protocol (IP), and is an IP network that integrates different networks based on IP. The structure may be an All IP network. In addition, the communication network includes a wired communication network, a mobile communication network (2G, 3G, 4G, LTE), a Wibro (Wireless Broadband) network, a High Speed Downlink Packet Access (HSDPA) network, a satellite communication network, and a Wi-Fi (WI-FI, Wireless Fidelity) network. Any suitable one of them can be selectively used.

The monitoring device 50 collects and analyzes the state information of the rock-cutting device 10, and can determine a series of rock excavation situations through the processing results accordingly, and the processing results and a series of rock excavation situations through the display device can be displayed.

For example, as shown in FIG. 7 , the monitoring device 50 includes a first sensor 500 , a second sensor 510 , a data collection unit 520 , a comparison analysis unit 530 , a display unit 540 and It may be configured to include a memory unit 550 .

The first sensor 500 may be mounted on the perforation portion 20 , and may output a first detection signal by sensing the withdrawal distance of the perforation portion 20 . This first sensing signal may be used as basic data for determining the puncture depth of the perforation part 20 .

At this time, when the outer casing 80 to be described below is provided, the measurement may be started from the end of the outer casing 80 as a reference for drawing out the perforation portion 20 .

The second sensor 510 may be mounted on one or more flow modules 300 selected from among the pair of flow modules 300 , and may detect a separation distance between the pair of flow modules 300 .

The second sensor 510 is preferably a non-contact sensor such as a photosensor or an ultrasonic sensor, and may output a second detection signal generated according to distance sensing. This second detection signal can be utilized as basic data for determining the crushing or splitting of the bedrock through the pair of flow modules 300 .

The data collection unit 520 may perform a function of a repeater for collecting the first detection signal and the second detection signal output from the first sensor 500 and the second sensor 510 .

The comparison analysis unit 530 receives the first detection signal and the second detection signal collected from the data collection unit 520, and compares and analyzes them with a preset reference signal to compare the perforation unit 20 and the arm unit ( 30) and a series of rock excavation conditions can be determined and output.

For example, the comparison analysis unit 530 determines that the drilling process by the drilling part 20 has started when the driving of the drilling part 20 starts, and analyzes the first detection signal while the driving is maintained to determine the excavation target. It is possible to determine the real-time drilling depth in the drilling process for the bedrock (1).

In addition, the comparison and analysis unit 530 may determine that after the driving of the perforation part 20 is finished, the driving of the granite part 30 is started and the gradation process has started, and the second detection is performed while the driving is maintained. By comparing and analyzing the signal with the set reference signal, it is possible to determine the degree of rock division or crushing in real time in the stepping process for the rock to be excavated (1).

That is, the comparative analysis unit 530 can estimate the degree of division or crushing of the rock 1 to be excavated through the separation distance between the pair of flow modules 300 .

In this case, the reference signal may be stored in the memory unit 550 to be described below, and this reference signal is a reference signal derived through a preliminary investigation of the characteristics of the rock to be excavated 1 . It is natural that the set value may be changed according to the degree of division or crushing according to the characteristics.

The display unit 540 displays the processing result information output from the comparison analysis unit 530 so that the manager can easily recognize the driving state or the excavation situation of the rock rock apparatus 10 .

The memory unit 550 may store an administrator setting value of the monitoring device 50, and the first detection signal and the second detection signal collected from the armpit device 10, as well as the driving or error for each device. Temporarily store event information according to it and can provide it at the request of an administrator.

The information stored in the memory unit 550 may be utilized as field work information or management information of the halam device 10 later.

On the other hand, the rock rock apparatus 10 according to an embodiment of the present invention may be configured as a unit unit detachable from the arm 3 of the excavator 2 as shown in FIG. 8, in which case the unit unit is At least two or more are rotatably connected to the arm 3 of the excavator 2 so that the rock 1 to be excavated can be rocked and the loading process can be performed after the rock stepping process.

As shown in FIG. 9A , the unit unit includes an accommodation space 800 for accommodating the perforation part 20 and the arm part 30 , and the perforation part 20 and the arm part 30 into the accommodating space. It may include an outer casing 80 provided with a transfer means for elevating from 800 to the front and rear directions, and a grab 90 coupled side by side to the side of the outer casing 80 .

At this time, at least two or more of the unit units may be coupled such that the grab 90 is rotationally driven on the same plane from the axis of the arm 3 of the excavator 2, for example, the unit units are spaced at 120 degrees apart. Three may be provided or four may be provided at intervals of 90 degrees as shown in FIG. 9B.

Here, in order to couple each unit unit to the arm 3 of the excavator 2 , a rotation bracket 4 may be provided in the present invention.

The rotation bracket 4 has a coupling hole 41 that can be coupled to the arm 3 of the excavator 2 with a pin 42 at the upper portion as shown in FIG. 9b, and the hydraulic pressure of the excavator 2 is configured. A hydraulic device is configured to transmit to the grab 90 of each unit unit.

The grab 90 is pin-coupled to the rotation bracket 4, and in order to rotate and drive from the rotation bracket 4, the hydraulic device and the hydraulic supply line are connected, and one end and the other end are respectively the rotation bracket 4 and the grab. By including the hydraulic cylinder 5 pin-coupled to the 90 , it is rotated on the same plane as the arm 3 in conjunction with the compression or expansion driving of the hydraulic cylinder 5 .

Here, rotating on the same plane as the arm 3 means rotating on the plane including the arm 3 , in other words, the unit unit including the grab 90 has the same plane as the arm 3 before and after rotation. It means to be on top.

The grab 90 allows the outer casing 80 accommodating the perforation portion 20 and the granite portion 30 to be positioned on the top of the rock 1 to be excavated to be excavated at a desired angle.

Although not shown in the drawing, the outer casing 80 positioned above the rock 1 to be excavated by the rotational driving of the grab 90 is provided in the front and rear directions of the perforation 20 and the halved arm 30 . It is provided with a transport means for moving in a straight line so that the rock can be drilled and divided. Here, the front in the front and rear directions refers to the end of the unit unit, that is, the perforation 20 side.

As an example, the transport means can transport the perforation 20 and the rock-cut section 30 in the front and rear directions by hydraulic pressure. By advancing with an appropriate hydraulic pressure, the perforation 20 first moves the rock. In this case, the conveying means may simply advance the perforation part 20 and the arm part 30, and preferably advance while applying minute vibrations in the front and rear directions, that is, while applying an appropriate impact. This allows the perforation of the bedrock to proceed faster.

Here, the above-mentioned conveying means may be applied in various ways according to known techniques such as a gear method as well as a hydraulic method presented as an example, and any physical method may be applied as long as it is a structure for linearly moving the perforation part and the arm part.

Hereinafter, a rock excavation process and a subsequent loading process of the rock rock apparatus using an excavator according to an embodiment of the present invention will be described with reference to FIGS. 10A to 10E .

As shown in FIG. 10A , by moving the rotation bracket 4 to mount the unit unit on the rock 1 to be excavated, the angle of the grab 90 of the unit unit is adjusted to adjust the angle of the rock 1 to be excavated. The excavation angle is determined.

And, as shown in FIGS. 10b and 10c, in each unit unit, the outer casing 80 transfer means is driven to move the perforation part 20 and the arm part 30 of each unit unit simultaneously or sequentially toward the front. let it be

Accordingly, the perforation 20 located in the front of each granite device 10 is entered by perforating the rock in a reverse trapezoidal shape.

Here, as an embodiment of the present invention, when four unit units are coupled to the rotation bracket 4 to perform perforation and gradation processes, respectively, as shown in the lower view of FIG. 10d , four granite devices 10 are square Although it is shown as being disposed in a shape and perforated in the shape of a square pyramid, it is not necessary to do so.

That is, the four unit units may be arranged in a rectangular shape by varying the installation distance from the axial direction of the rotation bracket 4 , and the perforations may be performed at different angles.

After the rock is drilled, the arm part 30 connected to the rear end of the drilling part 20 is driven, and the pair of flow modules 300 of the arm part 30 are spaced apart from each other by the expansion module 310. As the perimeter is expanded, the adjacent rock is pressed, and as a result, the rock is formed in the shape of a quadrangular pyramid with the head cut off by the resultant force of the pressing force acting on each of the rock blocks 30 .

In addition, since the divided rock can be gripped by the expanded flow module 300 of the divided rock unit 30, the divided rock 1 can be lifted as it is to be loaded or placed. In the lower view of FIG. 10D , the large rectangular dotted line is the granite line on the surface of the bedrock, and the inner small rectangular dotted line is the granite line at the bottom of the bedrock.

That is, in the case of FIG. 10D, it indicates that the rock is rocked by four unit units. Considering FIG. 10D, when the rock-cutting part 30 of the four rock-cutting devices 10 applies a force toward the center of the rock, the force of these The resultant force acts upward, that is, in the central direction, and at this time, the granite line of the rock progresses in the left and right directions of each granite device 10, and adjacent granite lines meet each other, so that the rock is formed into a cut-off quadrangular pyramid shape.

In actuality, the direction of the granite line may be slightly different depending on the state of the rock, but the overall shape may be halved into the shape of an inverted pyramid with a head cut as shown in the lower drawing of FIG. 10D .

In this way, when the four unit units are positioned in the shape of a quadrangular pyramid and drilling and grading, the drilling and grading of the rock can be performed even on a flat rock with no free surface other than the surface. In addition, after drilling and breaking the rock, when the unit unit is moved to place the bedrock 1, the grips 90 of each unit unit are rotated to open and the bedrock 1 is put down. For this purpose, the grab (70) should be spread at least in a direction parallel to the central axis of the rotation bracket (4) or more.

Therefore, it is preferable that the rotation of the grab 90 is rotatable from 10 degrees outward to 60 degrees inward in a direction parallel to the central axis of the rotation bracket 4 (here, the outer side is far from the central axis, and the inner side is the center) axial), preferably from 5 degrees outward to 50 degrees inward, and most preferably from 3 degrees outward to 40 degrees inward.

And the rotation angle to the inside is to facilitate the rock formation when there is no free surface on the side, and the rotation to the outside is to easily put down the perforated rock and the rock formation. If the angle of rotation inward is large, the rock mass is good but the amount of rock mass is reduced. If the angle of rotation inward is decreased, the rock mass is difficult but the amount of rock mass is increased. In addition, if the outward rotation angle is large, it is better to put down the rock, and if the outward rotation angle is small, it becomes difficult to put down the rock.

At this time, even if the grab 90 is not rotated outward, the perforation part 20 and the rock arm part 30 can be moved backward by using the transport means of the outer casing 80 to set down the rock, and also the grab 90 . In the direction parallel to the central axis of the rotation bracket 4, that is, even at 0 degrees to the outside, it will be sufficiently possible to put down the rock by the weight of the rock.

As described above, the granite device 10 of the present invention can perform drilling, granite, and transport with one device, so that it can be efficiently, quickly and easily carried out in performing rock excavation.

In addition, the rock rock apparatus 10 of the present invention is the case where small stones 6, etc., having small particles separated from the rock rock, remain in the excavation area in the rock rock and transport through each unit unit, as shown in FIG. 10E. By selectively rotating the grab 80, the existing stone 6 and the like can be easily excavated.

In this case, the perforation portion 20 and the arm portion 30 are positioned inside the outer casing 80 through the transport means of the outer casing 80 so that the grab 90 can freely rotate in the excavation area. let it be

As such, conventionally, when excavating rock, a large number of equipment, personnel, and a lot of time were required because drilling by a crawler drill, rock breaking by a rock crusher, cutting of excavated rock by a breaker, and loading (dump truck) of excavated rock by an excavator were performed. The rock-cutting device 10 of the present invention performs drilling, cutting or rock splitting of less-perforated rock blocks, and moving or removing (mucking) the separated rock blocks with one device, thereby providing vibration and noise occurrence is minimized, and the excavation work can be done efficiently and economically as well as very quickly.

Those skilled in the art from the above description will be able to see that various changes and modifications are possible without departing from the technical spirit of the present invention. Accordingly, the technical scope of the present invention should not be limited to the content described in the detailed description of the specification, but should be defined by the claims.
