Description

Drilling guide apparatus for rock drilling equipment

The present invention relates to a drilling guide device for rock drilling equipment that is provided in the rock drilling equipment and guides a user who performs a rock drilling operation by manipulating it.

In general, the rock drill apparatus is an equipment that drills holes in the rock, such as a rock drill to blast a rock drill or a rock rock with explosives, in order to perform a rock drilling operation. The angle can be adjusted on the boom of heavy equipment. It is connected and used.

This rock drilling equipment is rotatably connected to the end of the boom, and the angle is adjusted as a plurality of hydraulic cylinders connected to the boom expand and contract, and the guide arm is installed inside the guide arm and can be raised and lowered along the longitudinal direction of the guide arm. A lifting rod that is installed in the vertical direction, a first driving means installed on the guide arm for lifting and lowering the lifting rod; It is composed of a second driving means.

That is, the rock drilling equipment adjusts the angle of the guide arm to correspond to the drilling angle of the hole, lowers the lifting rod, and in the state that the drilling bit is in close contact with the rock, the lifting rod is moved according to the interlocking of the first and second driving means. As the drilling bit moves slowly downward and the drilling bit rotates at high speed, the hole is drilled as the drilling bit digs into the bedrock.

On the other hand, in order to economically, safely, and efficiently cut or blast rock, a plurality of holes must be continuously drilled at a constant azimuth angle, inclination, and interval.

That is, every time a hole is drilled in the bedrock, the azimuth and inclination of the lifting rod and the end position of the drilling bit are identified, and the azimuth and inclination of the lifting rod and the end position of the drilling bit are determined when drilling the previously drilled hole. Matching should be done in the same way.

However, the conventional rock drilling equipment does not provide a means for accurately informing the operator of the azimuth and inclination of the lifting rod and the position of the end of the drilling bit.

To this end, in the prior art, at least one worker other than the operator is put into the work site, and the operator is located near the rock drilling equipment and uses a compass and a level to inform the operator of the azimuth and inclination of the lifting rod and the position of the end of the drilling bit. It is being guided in a human way.

That is, there is no choice but to greatly depend on the skill level of the operator and the operator, the breathing between the operator and the operator is very important, and the breathing is also very important, and errors and deviations are inevitable due to manual work.

For this reason, it is very difficult to drill a hole at a constant azimuth angle, inclination, and interval using a rock drilling equipment, and there is a problem that a lot of work time is required when drilling a hole each time.

And as the azimuth angle, inclination, and interval of the hole are changed every time, there is a problem in that the granite work or the blasting work is not smooth. That is, the rock rock cannot be properly cut because the rock rock hole is not drilled at a certain angle during the rock rock work. In addition, when the blasting operation is performed, the charging hole is not drilled at a certain angle, which may cause safety accidents such as blasting or scattering due to the over-exaggeration or medicine-charge phenomenon.

Therefore, in order to reduce work time, reduce manpower consumption, and drill holes precisely, the operator alone sits in the driver's seat, accurately recognizing the azimuth and inclination of the hoistway and the position of the end of the drill bit, and drilling holes continuously at a certain azimuth, inclination, and interval. There is an urgent need to develop a drilling guide device for rock drilling equipment that can do this.

First, the detection sensor 10 is installed on the guide arm (G) to measure the azimuth and inclination of the guide arm (G) in real time.

That is, the detection sensor 10 rotates the guide arm (G) by driving the rock drilling equipment (B) so that the user sits in the driver's seat of the heavy equipment (E) and drills a hole in the rock at the desired azimuth, inclination, and spacing. The azimuth and inclination of the guide arm (G) according to the rotation of the guide arm (G) are measured in real time.

At this time, as the lifting rod (R) is installed parallel to each other on the guide arm (G) and the drilling bit (T) is installed at the end of the lifting rod (R), the azimuth and slope of the drilling bit (T) for drilling a hole in the bedrock and the azimuth and inclination of the guide arm (G) are the same.

That is, the azimuth and inclination of the guide arm (G) measured by the detection sensor 10 are the same as the azimuth and inclination of the punching bit (T), and the azimuth and inclination of the punching bit (T) are the rock by the punching bit (T). Since the azimuth and inclination of the hole drilled in the

Next, the camera 20 is installed on the guide arm (G) and positioned to face the bedrock to photograph the drilling work area of the bedrock where the drilling work is performed to generate the drilling area image 21 .

Here, the camera 20 shoots the drilling work area of the bedrock so that the end of the drilling bit T appears so that the user can check the end position of the drilling bit T through the drilling area image 21, and the drilling area image 21 ) is created.

On the other hand, the camera 20 guides the camera 20 so that the lens of the camera 20 faces the end of the punching bit T in order to show the drilling work area of the bedrock and the end of the drilling bit T in the drilling area image 21 together. It is preferable to be inclinedly installed on one side of the arm (G).

Therefore, in the drilling area image 21, as the user operates the bedrock drilling equipment (B), the end of the drilling bit (T) whose azimuth and inclination change appears. The equipment (B) can be easily operated.

Next, the perforated area image conversion unit 30 is formed by photographing the perforated area image 21 generated by obliquely photographing the perforating work area according to the installation angle of the camera 20 by the camera 20 in the vertical direction. convert to

That is, the puncturing area image conversion unit 30 converts the puncturing region image 21 so that the user views the puncturing work region vertically downward from the end of the puncturing bit T.

At this time, the punched area image conversion unit 30 uses the angle formed by the camera 20 and the punching bit T to convert the punched area image 21 generated by the camera 20 downward from the end of the punching bit T. It can be converted to form an image looking at the drilling work area vertically.

Therefore, the perforation area image 21 is converted into an image form viewed vertically downward from the end of the perforation bit T by the perforated area image conversion unit 30, so that the user checks the perforated area image 21 while checking the perforated area image 21. B) can be operated more easily.

Next, the user setting unit 40 sets the azimuth, the slope, and the puncture space of the hole to be drilled in the rock according to the input signal according to the user's manipulation.

That is, the user setting unit 40 allows the user to set the azimuth, the inclination, and the puncture space in order to constantly drill a plurality of holes in the rock through the rock drilling equipment (B).

In addition, the user setting unit 40 stores the azimuth angle, the inclination, and the puncture space of the hole to be drilled in the bedrock according to the input signal according to the user's operation to be distinguished from each other.

Therefore, when the user operates the rock drilling equipment (B) to drill a plurality of holes in the bedrock at the same azimuth, inclination, and celestial spacing, the azimuth, inclination, and celestial spacing stored in the user setting unit 40 are used to drill the same. can do.

Next, the interval guide image generating unit 50 arranges a plurality of concentric circles having different diameters at intervals corresponding to the celestial space set by the user in the user setting unit 40 to generate the interval guide image 51 . create

Next, the azimuth guide image generating unit 60 sets the azimuth and inclination of the guide arm (G) by the user when the user manipulates the rock drilling equipment (B) to adjust the azimuth and inclination of the guide arm (G). An azimuth guide image 61 for guiding to accurately match the azimuth and inclination is generated.

That is, the azimuth guide image generating unit 60 separates the current position corresponding to the azimuth and the inclination according to the rotation of the guide arm G, and the setting position corresponding to the azimuth and the inclination stored in the user setting unit 40, respectively. An azimuth guide image 61 is generated.

At this time, the azimuth guide image generating unit 60 represents the current position corresponding to the azimuth and inclination according to the rotation of the guide arm G as the first type 61a, and corresponds to the azimuth and inclination stored in the user setting unit 40 . An azimuth guide image 61 is generated by representing the set position to be set as a second type 61b having a different shape or color from the first type.

Here, the drilling guidance orientation image generating unit 70 may generate the drilling guidance orientation image 71 such that the pointing orientation guide line formed perpendicular to the free plane indicator line appears together with the free plane indicator line.

Next, the distance sensor 80 is installed on one side of the camera 20 to measure and output the distance between the camera 20 and the rock.

That is, as the distance sensor 80 measures the distance between the camera 20 and the bedrock and provides it, the distance on the pixel in the perforated area image 21 and the interval guide image 51 is proportional to the actual distance on the same basis. to be able to show

And in order to represent the distance on the pixel in the perforated area image 21 in proportion to the actual distance, the angle of view of the camera 20 known in advance along with the distance between the camera 20 and the bedrock may be used.

That is, if the distance between the camera 20 and the bedrock measured by the distance sensor 80 together with the angle of view of the camera 20 is used, the perforated area image 21 and the interval guide image ( 51) may represent the distance on the pixel in proportion to the actual distance.

Next, the output image generating unit 90 generates a first guide image 91 by merging the gap guide image 51 and the puncture guide orientation image 71 with the puncture area image 21, and the orientation is displayed. A second guide image 92 is generated by merging the azimuth guide image 61 with the azimuth image 62 , and a user setting image 93 for the user setting unit 40 is generated.

That is, the output image generating unit 90 is a drilling area image 21, a gap guide image 51 and a drilling guide so that the gap guide image 51 and the drilling guide azimuth image 71 are displayed on the drilling zone image 21. A first guide image 91 is generated by merging the azimuth images 71 .

And the output image generator 90 generates the second guide image 92 by merging the azimuth image 62 and the azimuth guide image 61 so that the azimuth guide image 61 is displayed on the azimuth image 62 .

In this case, the azimuth image 62 may include azimuth characters indicating east, west, south, and north, and a plurality of concentric circles having different diameters in order to display the azimuth angle according to the azimuth at regular intervals.

That is, the second guide image 92 may have a form in which the azimuth guide image 61 is displayed on the azimuth character and a plurality of concentric circles.

In addition, the output image generating unit 90 generates an input signal according to the user's manipulation to generate a user setting image 93 for the user setting unit 40 so that the user can set the azimuth, inclination, and celestial spacing of the hole. .

Therefore, the user can view the azimuth image 62 appearing in the second guide image 92 along with the puncture area image 21, the interval guide image 51 and the puncture guidance azimuth image 71 appearing in the first guide image 91. By manipulating the rock drilling equipment (B) using the and azimuth guide image 61, a plurality of holes can be drilled at the same azimuth angle, inclination and spacing.

Finally, the monitor 100 separates the first guide image 91 , the second guide image 92 , and the user set image 93 generated by the output image generator 90 , respectively, for each preset area. print out

At this time, as shown in FIG. 3 according to an embodiment, the monitor 100 displays a first area 101 on the left, a second area 102 on the upper right, and a third area 103 on the lower right. The first guide image 91 is output to the first region 101 , the second guide image 92 is output to the second region 102 , and the user set image is output to the third region 103 . (93) can be output.

Therefore, the user can set the azimuth, the inclination, and the puncture spacing of the hole to be drilled in the bedrock while visually confirming the user-set image 93 output to the third region 103 of the monitor 100 .

And the user visually confirms the azimuth image 62 and the azimuth guide image 61 included in the second guide image 92 output to the first region 101 of the monitor 100, while By operating the rock drilling equipment (B) so that the current position corresponding to the azimuth and inclination and the set position corresponding to the azimuth and inclination set by the user coincide, the hole can be drilled accurately at the set azimuth and inclination.

In addition, the user visually inspects the perforation area image 21, the interval guide image 51, and the perforation guide orientation image 71 included in the first guide image 91 output to the second area 102 of the monitor 100. By manipulating the rock drilling equipment (B) while confirming, the hole can be drilled according to the set drilling space while maintaining the orientation according to the set azimuth.

Here, the monitor 100 has a structure in which a touch screen is installed on the screen so that an input signal can be generated according to a user's manipulation through the user setting image 93 displayed on the third area 103 according to an embodiment.

However, according to another embodiment, a user input means including a plurality of buttons or dials may be included for the user setting unit 40 instead of the user setting image 93 . And the user input means may be installed on one side of the monitor 100 so that the user can conveniently operate.
