본 발명은 굴삭기에 장착되는 암반천공장치에 관한 것으로, 더욱 상세하게는 소형의 굴삭기에 암반천공장치를 장착하여 사용할 때 천공비트를 회전시켜주는 천공비트 회전모터를 감속전동모터로 구성함으로써 굴삭기로부터 순환시킬 수 있는 유량이 적은 경우에도 천공비트를 원활히 회전시켜 암반천공작업을 수행할 수 있도록 한 것이다.The present invention relates to a rock drilling machine mounted on an excavator, and more particularly, to circulate from an excavator by configuring a drill bit rotating motor that rotates the drilling bit when using a rock drilling plant installed on a small excavator as a deceleration motor. Even if the flow rate is small, rock drilling can be performed by rotating the drilling bit smoothly.

주지하다시피, 암반을 파쇄할 때에는 암반천공장치를 이용하여 암반에 일정 크기의 구멍을 뚫은 다음 그 구멍에 파쇄기를 넣어 암반을 균열시키게 되는데, 이때 사용되는 암반천공장치 중 굴삭기에 연결하여 사용되는 암반천공장치는 여러 가지 방식이 있으나, 최근에는 유압모터에 의해 회전되는 천공비트를 포함하는 천공부를 승하강시키면서 암반을 천공하는 것이 주류를 이루고 있는바, 본 출원인은 등록실용신안 제 361015 호, 등록실용신안 제 384177 호, 특허출원 제 2005-107055 호, 특허출원 제 2005-113220 호를 비롯하여 여러 건의 특허 및 실용신안을 통해 유압식 승하강모터에 의해 회전하는 체인에 의해 코아튜브를 승하강시킬 수 있는 암반천공장치를 개시한 바 있다.As is well known, when crushing a rock, a rock of a certain size is drilled into the rock using a rock mill, and then a crusher is put in the hole to crack the rock. There are various methods of drilling factory, but recently, the drilling of the rock while raising and lowering the drilling unit including the drilling bit rotated by the hydraulic motor is the main applicant. Through several patents and utility models, including Utility Model No. 384177, Patent Application No. 2005-107055, and Patent Application No. 2005-113220, the core tube can be raised and lowered by a chain rotated by a hydraulic lifting motor. It has started rock mill plant.

그러나, 상기한 본 출원인의 선출원 특허 및 실용신안 뿐 아니라 모든 굴삭기에 장착되는 암반천공장치는 천공비트를 회전시킬 수 있는 모터로 유압모터를 적용하고 있으므로 굴삭기의 크기가 대형인 경우에는 순환시킬 수 있는 유량이 많아 문제되지 않지만, 소형 굴삭기의 경우 순환시킬 수 있는 유량도 적게 되므로 이를 천공비트 회전모터로 순환시킨다하더라도 이러한 천공비트 회전모터를 포함한 암반천공장치를 구동할 때 큰 힘을 낼 수 없는 단점이 있으며, 특히 등록실용신안 제 384177 호와 같이 다수의 천공부를 구비한 암반천공장치의 경우 소형 굴삭기의 유량 한계로 인해 적용할 수 없는 단점도 있는 것이었다.However, as well as the applicant's patent application and utility model described above, the rock mill factory installed on all excavators uses a hydraulic motor as a motor that can rotate the drill bit, so that the excavator can be circulated when the size of the excavator is large. It is not a problem because there is a large flow rate, but in the case of a small excavator, the flow rate that can be circulated is small, so even if it is circulated with a perforated bit rotary motor, it is disadvantageous that a large force cannot be generated when driving a rock mill plant including such a perforated bit rotary motor. In particular, in the case of rock drilling apparatus equipped with a plurality of perforations, such as the Utility Model Registration No. 384177, there was also a disadvantage that can not be applied due to the flow rate limitation of a small excavator.

한편, 협소한 공간, 천장이 있는 건축물의 하부 등에서 암반 굴착작업을 할 때에는 그 진입공간의 협소함 때문에 대형 굴삭기에 암반천공장치를 장착하여 사용할 수 없고, 대신 소형 굴삭기에 암반천공장치를 장착하여 사용할 수밖에 없는데, 전술한 바와 같은 유량의 한계로 인해 협소한 공간 또는 천장이 있는 건축물의 하부와 같은 장소에서는 암반의 굴착작업이 원활히 이루어지지 못하는 단점이 있었다.On the other hand, when rock excavation work in a narrow space or a lower part of a building with a ceiling, it is impossible to use a rock drill plant on a large excavator because of the narrow space of entry. None, due to the limitations of the flow rate as described above, there was a disadvantage that the excavation of the rock was not smoothly performed in a narrow space or a place such as a lower part of a building having a ceiling.

또한, 상기와 같이 천공비트 회전모터를 유압모터로 구성할 경우에는 오일 순환을 위해 배관을 설치해야 하므로 부피가 늘어나고, 유량 제어를 위한 릴리프밸브, 스톱밸브 등의 부재가 구비되어야 하므로 암반천공장치가 구조적으로 매우 복잡해지는 단점도 있었다. In addition, when the perforated bit rotary motor is configured as a hydraulic motor as described above, since the pipes must be installed for oil circulation, the volume increases, and the rock drilling device is provided with a member such as a relief valve and a stop valve for flow control. There was also a disadvantage of being very complicated structurally.

본 발명은 이러한 점을 감안하여 제안된 것으로, 천공비트 회전모터로서 감속전동모터를 적용하고, 굴삭기의 일측에는 감속전동모터에 인가되는 전원을 공급하기 위한 발전기를 장착하여 소형 굴삭기를 통해 암반 굴착작업을 할 때 발전기로부터 생산된 전원을 이용하여 천공비트 회전모터를 작동시킬 수 있도록 함으로써 그 순환시킬 수 있는 유량이 작더라도 원활한 천공동작을 수행할 수 있는 굴삭기에 장착되는 암반천공장치를 제공하고자 하는 것이다.The present invention has been proposed in view of this point, and applies a deceleration electric motor as a drill bit rotation motor, and one side of the excavator is equipped with a generator for supplying power applied to the deceleration electric motor, and rock excavation work through a small excavator It is to provide a rock mill factory installed on an excavator that can perform a smooth drilling operation even if the flow rate that can be circulated is small by enabling the drill bit rotating motor to be operated using the power generated from the generator. .

이하, 본 발명을 제시되는 실시예와 첨부된 도면에 따라 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명이 적용되는 굴삭기는 소형의 굴삭기로 이루어짐이 바람직하며, 굴삭기에 장착되는 암반천공장치는 굴삭기에 연결하여 사용하는 암반천공장치면 어떤 것이든 가능한 것으로, 이하에서 설명하는 암반천공장치에 국한되지는 않는다.Excavator to which the present invention is applied is preferably made of a compact excavator, the rock drilling plant is equipped with any of the rock drilling device used in connection with the excavator, it is not limited to the rock drilling device described below Does not.

도시된 바와 같이, 본 발명이 적용되는 굴삭기에 장착되는 암반천공장치는 일정거리 이격되는 한 쌍의 지지판(10) 사이에 상부고정판(11), 중간고정판(12), 하부받침판(13)이 설치되고, 중간고정판(12)과 하부받침판(13)의 사이 앞쪽에는 천공비트(21)를 갖는 코아튜브(20)가 천공비트 회전모터(22)에 의해 회전가능하게 설치되며, 중간고정판(12)과 하부받침판(13)의 사이에는 한쌍의 가이드봉(14)이 설치되고, 코아튜브(20)의 상부에는 가이드봉(14)에 승하강 가능하게 끼워진 승하강연결구(23)가 고정되며, 지지판(10) 사이 안쪽에는 승하강연결구(23)를 승하강시켜 코아튜브(20) 및 천공비트(21)를 승하강시키는 승하강장치(30)가 설치되고, 지지판(10)의 배면측에는 상기한 각 요소로 오일을 순환시키기 위한 조작부(40)가 위치되며, 이러한 상태로 굴삭기(P)의 아암과 연결되어 이루어진다.As shown, the upper armrest plate 11, the middle fixing plate 12, the lower support plate 13 is installed between a pair of support plates 10 spaced apart a certain distance is mounted on an excavator to which the present invention is applied The core tube 20 having the drilling bit 21 is rotatably installed by the drilling bit rotating motor 22 in front of the intermediate fixing plate 12 and the lower support plate 13, and the intermediate fixing plate 12. A pair of guide rods 14 are installed between the lower support plate 13 and a lowering connector 23 fixed to the guide rods 14 to be lifted up and down at an upper portion of the core tube 20. An elevating device 30 for elevating the elevating connector 23 to elevate the core tube 20 and the drill bit 21 is provided between the inner sides of the elevating connector 23, and the rear side of the supporting plate 10 is provided above. The operation part 40 for circulating oil to each element is located, and in this state, it is connected with the arm of the excavator P. It has been achieved.

또한, 도면상에는 승하강장치(30)를 체인구동방식으로 구성된 것을 예로 하여 도시하였지만, 이외에도 스크류 구동방식, 랙-피니언 구동방식, 실린더 구동방식 등 천공부를 승하강시킬 수 있는 구성이면 어떤 것이든 적용가능하다. In addition, although the lifting device 30 is illustrated as an example of a chain driving method in the drawing, any configuration that can raise and lower the perforations such as a screw driving method, a rack-pinion driving method, a cylinder driving method, etc. Applicable.

이러한 일반적인 암반천공장치에 있어서, 본 발명에서는 천공비트 회전모터(22)는 감속전동모터로 구성하고, 굴삭기(P)의 일측에는 천공비트 회전모터(22)에 공급되는 전력을 발생시키는 발전기(50)를 장착하며, 조작부(40)에는 발전기(50)를 구동시켜 이로부터 발생된 전원이 천공비트 회전모터(22)로 인가되게 하는 스위치(51)를 구비한 것이다.In such a general rock drilling device, in the present invention, the drill bit rotating motor 22 is configured as a deceleration electric motor, and the generator 50 generates power supplied to the drill bit rotating motor 22 on one side of the excavator P. ), The operation unit 40 is provided with a switch 51 for driving the generator 50 so that the power generated therefrom is applied to the perforated bit rotation motor 22.

이와 같이 구성된 본 발명에 따른 굴삭기에 장착되는 암반천공장치는 다음과 같은 작용을 한다.The rock drilling plant mounted on the excavator according to the present invention configured as described above functions as follows.

먼저, 협소한 장소 또는 천장이 있는 건물의 지하와 같은 공간에 굴삭기(P)가 진입하여 암반 굴착작업을 수행할 때 이러한 장소는 매우 협소하므로 소형의 굴삭기(P)를 사용할 수밖에 없다.First, when an excavator (P) enters a space such as a basement of a narrow place or a building with a ceiling and performs rock excavation work, such a place is very narrow, and thus a small excavator (P) cannot be used.

소형의 굴삭기(P)를 상기와 같은 협소한 장소에 진입시킨 상태에서 그 아암을 조작하여 암반천공장치를 지면 또는 암반면에 착지시킨 상태에서 천공비트 회전모터(22)를 작동시켜 천공비트(21)를 회전시키게 되고, 승하강장치(30)를 통해 승하강연결구(23)를 서서히 하강시키게 되면 승하강연결구(23)와 고정되어 있는 코아튜브(20)가 서서히 하강하면서 천공비트(21)가 암반면과 접촉되어 암반 천공이 이루어지게 되며, 암반 천공작업을 마친 후에는 각 구멍에 별도의 파쇄기를 투입 작동시켜 암반을 균열시킬 수 있게 된다.The drill bit rotary motor 22 is operated by operating the drill bit rotating motor 22 in the state where the rock drilling mill is landed on the ground or the rock surface by operating the arm in the state where the small excavator P is entered in the narrow place as described above. Rotate), and gradually lowering the elevating connector (23) through the elevating device (30) while the drill tube (21) while the core tube (20) fixed with the elevating connector (23) is gradually lowered The rock surface is brought into contact with the rock surface, and after completion of rock drilling, a separate crusher is put into each hole to crack the rock.

이때, 본 발명에 따른 천공비트 회전모터(22)는 감속전동모터로 이루어지고, 이러한 천공비트 회전모터(22)에 전원을 인가하기 위한 전력을 발생시키는 발전기(50)는 굴삭기(P)의 일측에 장착되어 있으므로 암반천공장치 배면측에 위치한 스위치(51)를 온시켜 발전기(50)를 구동하게 되면 이로부터 발생된 전력이 천공비트 회전모터(22)에 공급되어 천공비트 회전모터(22)가 소형 굴삭기(P)로부터 순환되는 유압과 상관없이 자체적으로 회전될 수 있으며, 따라서, 소형 굴삭기(P)로부터 순환되는 유압은 승하강장치를 구동하는 데에만 적용할 수 있어 그 유량이 적음에도 불구하고 암반 굴착작업이 원활하게 진행될 수 있다.At this time, the drilling bit rotation motor 22 according to the present invention is made of a reduced speed motor, the generator 50 for generating power for applying power to the drilling bit rotation motor 22 is one side of the excavator (P) Since it is mounted on the switch 51 located on the back of the rock drilling device to drive the generator 50, the electric power generated therefrom is supplied to the drill bit rotary motor 22, the drill bit rotary motor 22 is Regardless of the hydraulic pressure circulated from the small excavator (P) can be rotated by itself, therefore, the hydraulic pressure circulated from the small excavator (P) can be applied only to drive the lifting device, despite the low flow rate Rock excavation work can proceed smoothly.

도 5a 및 도 5b는 암반천공장치에서 천공부가 2개 또는 3개 구비된 다른 실시예시도로서, 천공부가 2개 또는 3개로 구성된 경우에도 천공비트 회전모터(22)를 감속전동모터로 구성하게 되면 굴삭기가 소형인 경우에도 암반굴착작업을 원활히 진행할 수 있다.5A and 5B illustrate another embodiment in which two or three perforations are provided in the rock drilling device, when the perforated bit rotation motor 22 is configured as a deceleration electric motor even when two or three perforations are configured. Even if the excavator is small, rock drilling can proceed smoothly.

한편, 건축물의 지하와 같이 밀폐된 공간에서 암반굴착작업시에는 굴삭기(P)의 구동에 따른 매연과 발전기(50)의 구동에 따른 매연이 대기중으로 순환되지 못하고 실내에 채워지게 되므로 자칫 위험한 상황을 초래할 수 있게 되는데, 이럴 경우에는 발전기(50)를 구동하지 않고 건축물로부터 전원을 리드하여 천공비트 회전모터(22)에 연결해줌으로써 발전기(50) 구동에 따른 매연을 줄일 수 있도록 함이 바람직하다.On the other hand, when rock excavation work in an enclosed space, such as the basement of the building, soot smoke caused by the operation of the excavator (P) and the smoke generated by the drive of the generator 50 is not circulated to the atmosphere, it is filled with a dangerous situation In this case, it is preferable to reduce the smoke caused by driving the generator 50 by connecting the power source from the building to the perforated bit rotation motor 22 without driving the generator 50.

또한, 때로는 공사현장에 동력전기가 있을 시에는 필요에 따라 발전기를 사용하지 않고 공사현장의 동력전기를 사용할 수도 있다.In addition, sometimes, when there is a power electricity in the construction site, it is possible to use the power electricity of the construction site without using a generator if necessary.

이상에서 설명한 바와 같이, 본 발명은 소형의 굴삭기에 적용되는 암반천공장치에서 천공비트 회전모터를 감속전동모터로 구성한 것이므로 기본적으로 소형의 굴삭기로부터 순환되는 오일의 유량이 부족하지만 이러한 오일이 암반천공장치의 천공비트를 승하강시키는 데에만 사용되고, 천공비트 회전모터는 굴삭기 일측에 장착되어 있는 발전기로부터 전원을 인가받아 회전되는 것이어서 그 굴착작업이 원활히 진행될 수 있으며, 특히 협소한 공간이나 천장이 있는 건축물의 지하와 같이 협소한 장소에서 불가분 소형의 굴삭기를 사용하여야 할 때 더욱 좋은 효과를 나타낼 수 있는 것이다.As described above, the present invention is because the drilling bit rotation motor in the rock drilling apparatus applied to a small excavator is configured as a deceleration motor, the flow rate of the oil circulated from the small excavator is basically a lack of such a rock drilling apparatus It is used only to raise and lower the drill bit of the drill bit, and the drill bit rotary motor is rotated by receiving power from the generator mounted on one side of the excavator, so that the excavation work can be performed smoothly, especially in a structure having a narrow space or a ceiling. When using an indispensable small excavator in a narrow place, such as underground, it can have a better effect.
