Description

회전식 콘크리트 면삭기의 초경팁 개량 구조 {Improved structure of cemented-carbide tip for a rotary type concrete surface cutting machine}Improved structure of cemented-carbide tip for a rotary type concrete surface cutting machine

본 고안은 회전식 콘크리트 면삭기의 초경팁 개량 구조에 관한 것으로, 대형빌딩, 수로공사등의 기초공사에 많이 시공되고 있는 지하연속벽이나 지수벽의 고르지 못한 벽면에 대해 소정의 설계치수에 맞게 면고르기 작업을 실시하는 데 사용되는 회전식 콘크리트 면삭기의 초경팁의 개량 구조 및 이의 설치구조를 개량한 고안에 관한 것이다.The present invention relates to the improved structure of cemented carbide tips for rotary concrete face grinder, and to select the surface according to the predetermined design dimension for the uneven wall surface of underground continuous wall or exponential wall, which is frequently used in foundation works such as large buildings and water works. The present invention relates to an improved structure of a cemented carbide tip of a rotary concrete facer used to carry out work, and to an improved design thereof.

근래에는 대형빌딩, 수로공사등의 기초공사에 있어 토류벽이나 지수벽을 시공하는 경우에 지하연속벽 공법을 많이 채택하고 있는 데 이러한 지하연속벽 공법에 의해 철근콘크리트벽을 완성하는 경우에 통상적으로 도랑의 형상 및 굴착장비의 버킷자국, 설계치수를 벗어난 초과 굴삭등에 의해 지하연속벽이나 지수벽의 측면이 고르지 못하고 부풀림 현상이 발생하는 등 설계치수에서 크게 벗어나는 현상이 나타나게 된다. 따라서, 연속벽의 내부에 있는 흙을 퍼낸 후 노출되는 연속벽의 측면에 대해 소정 설계치수에 맞게 면고르기 작업을 실시하게 된다.Recently, when constructing earth and water walls in large-scale building and waterway construction, many underground continuous wall methods have been adopted, and when the reinforced concrete wall is completed by the underground continuous wall method, it is usually ditched. Due to the shape of the swell, bucket marks of the excavation equipment, and excess excavation beyond the design dimensions, the lateral continuity wall or the exponent wall is uneven and swells, causing significant deviations from the design dimensions. Therefore, the surface of the continuous wall is exposed to the surface of the continuous wall to be exposed to the predetermined design dimensions to perform the leveling operation.

이러한 면고르기 작업은 주로 굴삭기에 장착한 유압브레커로서 파쇄하거나 착암기를 이용하여 작업자가 직접 수공작업으로 실시하고 있으나 이 작업은 과도한소음과 분진이 발생하여 작업조건이 불량하고 소요 작업시간이 매우 길어지며 공사기간의 연장으로 인건비가 상승되는 등 각종 문제점이 있다.The surface picking work is mainly a hydraulic breaker mounted on an excavator, which is performed by a worker by crushing or by using a rock drill. However, this work is caused by excessive noise and dust. There are various problems such as increase in labor costs due to the extension of the construction period.

따라서, 이러한 문제점을 해소하는 것으로 특허 공고번호 제1996-4408호 회전식 콘크리트 면삭기 및 그에 사용되는 초경팁이 제안되어 나온바 있다.Therefore, the patent publication No. 1996-4408 rotary concrete face grinder and a carbide tip used therein have been proposed to solve this problem.

상기 면삭기의 구조는 굴삭기의 디퍼스틱에 연결장치되는 지지체에 지지되는회전드럼의 원주면상에 헬리컬선상에서 독립적으로 부착 고정된 다수개의 홀더에초경팁을 갖는 커터생크를 삽입고정하고 상기 회전드럼을 착탈가능하게 회전지지하는 지지체를 소형굴삭기의 디퍼스틱에 연결장치하여 상기 굴삭기의 유압력에 의한 회전모터의 회전력으로 상기 회전드럼을 일정속도로 회전시켜 소음 및 분진 발생을 감소시키고, 연속벽의 균열을 발생시키는 문제점을 제거하고 높은 작업속도로 지한연속벽의 콘크리트면을 설계치수에 맞게 다듬질할 수 있게 되어 있다.The structure of the surface excavator is fixed to insert the cutter shank having a carbide tip in a plurality of holders that are independently attached and fixed on a helical line on the circumferential surface of the rotating drum supported on the support that is connected to the deflector of the excavator and the rotating drum Removably supported support is connected to the deflector of the small excavator to rotate the rotating drum at a constant speed by the rotational force of the rotary motor by the hydraulic force of the excavator to reduce noise and dust generation, cracks in the continuous wall It is possible to trim the concrete surface of the continuous wall at high working speed according to the design dimensions.

그러나 이는 회전드럼의 홀더에 착탈가능하게 끼워지는 초경커터는 생크와 이의 선단부에 부착되는 초경합금재로 된 3개의 초경팁을 연접시킨 형상으로 이루어지고 이는 홀더에 착탈 가능하게 탄성 결합되면서 회전되지 않게 고정되어 있는 구조이므로 초경팁의 전체가 고르게 마모되지 않고 한쪽으로만 마모되는 문제점이 있었으며 특히 3개의 초경팁의 나란히 부착되어 끝단이 평평하므로 연마할 콘크리트면을 깊이 파고 들면서 다듬질할 수 없는 문제점이 있었다.However, the cemented carbide cutter detachably fitted to the holder of the rotating drum has a shape in which the cemented carbide tip made of the cemented carbide material attached to the shank and its tip is connected to the holder, which is fixed to the holder while being elastically coupled to the holder. Since the entire structure of the carbide tip was not worn evenly, only one side was worn. Particularly, three cemented carbide tips were attached side by side, so that the ends were flat.

그리고 지지체와 회전드럼은 일측을 연결구에 의해 선회가 가능하도록 결합하고 타측은 진동을 흡수하는 탄성부재로서 탄력 설치한 구조이므로 파쇄시 발생되는 진동을 일측의 탄성부재로만 흡수하게 되므로서 진동 흡수효과가 미약하여 파쇄시의 진동이 디퍼스틱을 통해 굴삭기로 직접 전달됨에 따라 장치의 고장을 발생시키고 소음과 분진을 크게 발생시키는 등 여러가지의 폐단이 있었다.And the support and the rotating drum is coupled to one side so that it can be rotated by the connector, and the other side is elastically structured as an elastic member that absorbs vibration, so the vibration generated when crushing is absorbed only by the elastic member on one side, so the vibration absorption effect is improved. As the vibration of the crushing is transmitted to the excavator directly through the deflector, there are various closures such as generating a malfunction of the device and generating noise and dust.

본 고안의 목적은 종래의 문제점을 해소하는 데 있는 것으로, 회전드럼에 헬리컬 선상으로 부착되는 초경팁을 탄피형상으로 형성하여 홀더에 회전자재되게 끼워 설치하므로서 초경팁이 회전되면서 콘크리트면을 고르게 보다 깊이 연삭할 수 있게 하고 지지체와 회전드럼을 다수개의 축으로 연결하되 스프링으로 탄력 설치하여 진동 흡수효과를 배가시키므로서 종래의 폐단을 해소한 회전식 콘크리트 면삭기의 초경팁 개량 구조를 제공하는 데 있다.The purpose of the present invention is to solve the conventional problems, by forming a carbide tip attached to the rotating drum in a helical shape in the casing shape and inserting it into the holder to rotate the cemented carbide tips while rotating the concrete evenly deeper It is possible to grind and connect the support and the rotating drum in a plurality of shafts, but elastically installed by the spring to double the vibration absorption effect to provide a carbide tip improved structure of the rotary concrete facer that eliminates the conventional end.

도 1은 본 고안의 초경팁 구조가 설치된 회전식 콘크리트 면삭기의 예시도이고, 도 2는 본 고안의 측면 일부 단면도이며, 도 3은 본 고안의 요부 분해 사시도이고, 도 4는 본 고안의 요부 단면도로서, 본 고안은 홀더(1)를 구비한 회전드럼 (2)과, 상기 회전드럼(2)의 브라켓트(3)와 연결되어 굴삭기의 디퍼스틱(미도시)에 착탈가능하게 장착되는 지지부(4)와, 상기 회전드럼(2)의 원주면상에 헬리컬 형상으로 배치 고정된 홀더(1)내에 끼워져 회전드럼(2)의 회전에 따라 콘크리트면을 깍아내는 초경팁(5)으로 이루어진 통상의 콘크리트 면삭기에 있어서, 상기 회전드럼 (2)과 지지부(4)의 플랜지(4')를 축봉(6)으로 연결하되 스프링(7)을 끼워 탄력설치하고, 홀더(1)의 외면에 삽지공(8)이 회전드럼(2)의 회전방향으로 관통된 삽입관 (9)을 일체로 형성하여 이의 삽지공(8)에 초경합금(10)이 뾰족한 끝단에 부착된 탄피형상의 초경팁(5)을 삽입하되 상단부의 단입부(11)에 끼운 스냅링(12)의 돌기 (12')가 삽지공(8) 내벽의 요홈(13)에 끼워져 걸리도록 설치하여서 됨을 특징으로 하는 구조이다.Figure 1 is an exemplary view of a rotary concrete face machine is installed cemented carbide tip structure of the present invention, Figure 2 is a partial cross-sectional side view of the present invention, Figure 3 is an exploded perspective view of the main part of the present invention, Figure 4 is a sectional view of the main part of the present invention As a design of the present invention, a rotating drum 2 having a holder 1 and a support 4 connected to a bracket 3 of the rotating drum 2 and detachably mounted on a excavator's differential (not shown) are provided. ), And a conventional concrete chamfer consisting of a cemented carbide tip (5) inserted in a holder (1) fixed in a helical shape on the circumferential surface of the rotating drum (2) to shave the concrete surface according to the rotation of the rotating drum (2). In this case, the rotating drum (2) and the flange (4 ') of the support portion 4 is connected to the shaft rod (6), the spring 7 is fitted to the elastic installation, the insertion hole (8) on the outer surface of the holder (1) Insertion holes (9) formed integrally with the insertion tube (9) penetrated in the rotational direction of the rotary drum (2) (8) Insert the cemented carbide tip 5 attached to the pointed end of the cemented carbide alloy 10, but the projection 12 'of the snap ring 12 inserted into the end portion 11 of the upper end is recessed in the inner wall of the insertion hole 8 It is a structure characterized in that it is installed so as to be hooked.

이와같이 된 본 고안은 지지부(4)를 굴삭기의 디퍼스틱에 연결핀(미도시)을 이용하여 연결시키고 회전드럼(2)의 내부에 설치된 구동모터(미도시)를 구동시키게 되면 구동모터가 회전하면서 소정의 회전속도로 회전드럼을 회전시키게 되므로 작업자가 굴삭기의 부움과 디퍼스틱을 작동시켜 연속벽 정리작업면에 회전드럼(2)을 접촉시키게 되면 회전드럼(2)의 표면에 헬리컬 선상으로 배치된 홀더(1)에 끼워진 초경팁(5)이 회전되면서 연속벽의 튀어나온 부분을 깍게 되고 이때 헬리컬선상으로 배치된 초경팁(5)이 헬리컬선상으로 회전되면서 콘크리트면을 반복적으로 균일하게 다듬질하고, 파쇄시의 충격과 진동은 회전드럼(2)의 브라켓트(3)와 지지부(4)의 사이에 끼워져 탄력설치된 스프링(7)에 의해 흡수되어 지지부(4)로의 전달이 일부 차단되므로서 기계의 고장을 방지하게 되는 데 이때 지지부(4)와 회전드럼(2)의 브라켓트(3)는 종래와 같이 일부를 스프링(7)으로 탄력설치하지 않고 전체를 스프링(7)으로 탄력 설치하였으므로 회전드럼(2)을 통해 전달되는 파쇄시의 충격과 진동은 다수개로 설치한 스프링(7)에 의해 거의 흡수됨에 따라 기계장치의 고장을 감소시키게 되는 효과가 상승된다.The present invention is thus connected to the support portion 4 using a connecting pin (not shown) to the excavator's deflector and driving the drive motor (not shown) installed inside the rotary drum (2) while the drive motor rotates Since the rotating drum is rotated at a predetermined rotational speed, when the operator touches the rotating drum 2 on the continuous wall cleaning work surface by operating the excavator's boolean and dipstick, the helical line is disposed on the surface of the rotating drum 2. Carbide tip 5 inserted in the holder (1) is rotated to cut off the protruding part of the continuous wall and at this time, the carbide tip (5) arranged in a helical line is repeatedly rotated in a helical line to uniformly repeat the concrete surface, The impact and vibration during the crushing are inserted between the bracket 3 and the support 4 of the rotating drum 2 and are absorbed by the spring 7 that is elastically installed so that the transmission to the support 4 is partially blocked. In this case, the bracket 4 of the support part 4 and the rotating drum 2 is elastically installed in its entirety with the spring 7 instead of installing the elastic part with the spring 7 as in the related art. The impact and vibration during crushing transmitted through (2) are almost absorbed by the springs 7 installed in plural, thereby increasing the effect of reducing the failure of the mechanical device.

특히 본 고안의 초경팁(5)은 초경합금(10)이 뾰족한 끝단에 부착된 탄피형상으로 이루어져 회전드럼(2)의 회전방향으로 관통된 삽입관(9)의 삽지공(8)에 끼워져 있되 상단부의 단입부(11)에 끼운 스냅링(12)의 돌기(12')가 삽지공(8)내벽의 요홈(13)에 끼워져 걸리도록 설치되어 있으므로 초경팁(5)은 삽지공(8)의 내부에서 스냅링(12)에 의해 빠지지는 않으면서 자유롭게 회전이 이루어지게 됨에 따라 콘크리트면을 다듬질시 충격과 진동에 의해 초경팁(5)이 회전되면서 파쇄가 이루어져초경팁(5)의 전체가 고르게 마모되고 뾰족한 단부가 콘크리트 면을 깊이 파고들면서 파쇄하게 되므로 단부가 뾰족하지 않고 평탄한 종래의 초경커터보다 파쇄효과가 더욱 상승되어 공기를 단축시킬 수 있게 되는 것이다.In particular, the cemented carbide tip 5 of the present invention is made of a casing shape in which the cemented carbide 10 is attached to the pointed end, and is inserted into the insertion hole 8 of the insertion tube 9 penetrated in the rotational direction of the rotating drum 2, but the upper end portion Since the projection 12 'of the snap ring 12 inserted into the stepped portion 11 is fitted to fit into the groove 13 of the inner wall of the insertion hole 8, the cemented carbide tip 5 has a snap ring inside the insertion hole 8 12) As it is freely rotated without falling out, the cemented carbide tip 5 is crushed by impact and vibration when the concrete surface is being trimmed, and the entire cemented carbide tip 5 is worn evenly and the pointed end is Since the crushed while deeply digging the concrete surface will be shorter than the conventional cemented carbide cutters that are not pointed and flattened to shorten the air.

이와같이 본 고안은 면삭작업시 발생되는 충격과 진동을 흡수하는 효과가 크고 초경팁(5)의 전체가 고르게 마모되어 수명을 연장시키며 파쇄면을 깊이 파고들면서 파쇄시킬 수 있어 파쇄효과가 상승되는 등 그 효과가 매우 크다.In this way, the present invention has a great effect of absorbing the shock and vibration generated during the grinding operation, and the entire carbide tip 5 is evenly worn to extend the service life and can be crushed while digging deeply into the crushed surface. The effect is very big.
