Description

노면 절삭 장치Road cutting device
본 발명은 노면 절삭 장치에 관한 것으로서, 보다 상세하게는 정역회전에 의해서도 동일한 절삭 기능을 수행할 수 있도록 하는 노면 절삭 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road cutting device, and more particularly, to a road cutting device capable of performing the same cutting function even by forward and reverse rotation.
일반적으로 노면은 장시간을 사용하다 보면 마모 또는 손상이 발생되므로 부분적으로 또는 전면을 새롭게 교체하는 노면 보수 공사를 해야만 한다.In general, the road surface is worn or damaged after prolonged use, so it is necessary to partially or completely renew the road surface.
특히, 우레탄 또는 엘라스트라 칩으로 탄성 포장을 하는 육상용 트랙과 같은 노면은 다양한 방식으로 보수가 이루어지도록 하고 있다.In particular, road surfaces, such as tracks for tracks that are elastically wrapped with urethane or elastra chips, can be repaired in various ways.
즉 기존의 트랙을 완전히 제거하고 새로운 트랙을 시공하는 방법(두께 13㎜)이 있고, 기존의 손상된 트랙 위에 우레탄을 도포하고 엘라스트라 칩을 살포하는 방법(두께 18㎜이상)도 있으며, 기존의 트랙 상층부(약 4㎜)만을 표면 절삭 후 재포장(5㎜)하는 방법(두께 13㎜) 및 기존의 트랙위에 공인된 트랙용 고무판을 설치하는 방법 등이 국제 육상 연맹에 의해서 규정하고 있어 선수 보호나 경기력 향상에 적합하도록 하고 있다.That is, there is a method of completely removing the existing track and constructing a new track (13 mm thick), and a method of applying urethane and spraying the elastra chip (thickness 18 mm or more) on the existing damaged track. The method of installing and resurfacing (5 mm) only the upper layer (approximately 4 mm) after cutting the surface (thickness 13 mm) and installing a certified track rubber plate on the existing track are prescribed by the International Athletic Federation. It is suitable for improving performance.
또한 최근에는 특정한 선수를 위한 트랙이 아니더라도 우레탄을 이용하는 노면 보급이 급격하게 증가하고 있는 추세이다.In recent years, even though it is not a track for a particular athlete, the road supply using urethane is increasing rapidly.
노후 또는 손상된 트랙의 노면 보수를 위해 최근 가장 많이 사용되고 있는 방법은 노후 또는 손상된 트랙의 표층(두께 4㎜)만을 절삭한 후 우레탄을 도포하고 그 위에 엘라스트라 칩을 살포하여 재포장(두께 5㎜)하는 방법으로서, 저렴한 공사비의 장점을 제공한다.Recently, the most popular method for repairing old or damaged tracks is to cut only the surface layer of the old or damaged tracks (thickness 4mm), and then re-pave them by applying urethane and spraying elastra chips on them. As a way, it provides the advantages of low cost of construction.
이와 같은 노면의 보수를 위하여 제안된 것이 노면 절삭 장치이며, 이런 노면 절삭 장치로서 제안된 것 중 가장 대표적인 것이 등록특허 제597949호(노면 절삭 장치)이다.Proposed for repairing such a road surface is a road surface cutting device, the most representative of these proposed as a road surface cutting device is Korean Patent No. 597949 (road cutting device).
하지만 기등록특허의 노면 절삭 장치는 실제적으로 노면을 절삭하도록 구비되는 원기둥 형상의 절삭부에는 복수 개로 구비되는 절삭판들 각각에 외주면을 따라 톱니가 복수 개로서 형성되도록 하고, 이들 각 톱니에는 절삭날이 고정되도록 하고 있어 절삭날을 각 톱니에 일일이 고정시키기가 매우 번거롭고, 따라서 대개는 절삭날의 마모 시 절삭날만을 교체하는 것이 아니라 절삭판을 교체시키게 되므로 교체 및 유지 비용이 상승되는 폐단이 있다.However, the road surface cutting device of the registered patent is to be formed as a plurality of teeth along the outer circumferential surface of each of the cutting plate is provided in a plurality of cylindrical cutting portion provided to actually cut the road surface, each of the saw blades It is very difficult to fix the cutting edge to each tooth individually, so that when the cutting edge wears, the cutting plate is replaced, instead of replacing only the cutting edge.
또한 기등록특허에서 절삭날은 장시간 사용 시 마모가 되며, 이렇게 마모되었을 경우 커팅 능력이 급격히 상실되면서 노면을 제대로 절삭하지 못하고 지나치게 누르는 압력만을 상승시키게 되므로 절삭하고자 하는 두께를 넘어 그 아래쪽의 제품에까지 충격을 주게 되는 동시에 접착력을 상실시켜 제품 손상 및 하자를 유발하게 되는 원인이 되고 있다.In addition, in the registered patent, the cutting edge wears out for a long time, and if it is worn out, the cutting ability is sharply lost and the surface is not cut properly and only the pressure that is excessively increased increases the impact beyond the thickness to be cut. At the same time, the adhesive force is lost, causing product damage and defects.
특히 톱니에 고정되는 절삭날들은 칼날이 일방향으로만 형성되는 방향성을 갖고 있으므로 일방향만으로만 절삭 효과가 있어 사용 주기 및 교체 주기가 짧은 비경제적인 문제가 있다.In particular, the cutting edge fixed to the tooth has a directionality that the blade is formed only in one direction, so there is a cutting effect in only one direction, there is an uneconomical problem of short use cycle and replacement cycle.
본 발명은 상기한 폐단과 문제점을 해결하기 위한 것으로서, 본 발명은 양방향으로 칼날 사용이 가능하도록 함으로써 칼날의 사용 수명이 대폭적으로 연장되도록 하고, 칼날의 부분적인 교체가 가능토록 하는 노면 절삭 장치를 제공하는데 주된 목적이 있다.The present invention is to solve the above-mentioned closure and problems, the present invention is to enable the use of the blade in both directions to significantly extend the service life of the blade, to provide a road surface cutting device that allows partial replacement of the blade. There is a main purpose.
또한 본 발명은 칼날의 장착 및 교체가 용이토록 하는 노면 절삭 장치를 제공하는데 다른 목적이 있다.It is another object of the present invention to provide a road cutting device to facilitate mounting and replacement of the blade.
상기한 목적 달성을 위하여 본 발명은 중앙에는 주축이 연결되는 주축결합홀을 형성하고, 외주연 단부는 주면을 따라 균등하게 구분되도록 하여 일정 폭을 일단에서 타단으로 경사지게 한 결합부를 연속해서 형성하는 원형의 고정판과; 상기 고정판의 각 결합부와 각각 동일한 길이로서 형성되고, 상기 고정판의 중앙으로부터 외주연 단부보다는 외측으로 보다 돌출되게 하여 서로 대칭이 되는 경사각으로 외주면을 따라 톱날이 연속해서 형성되도록 하는 원호 형상의 절삭날과; 상기 고정판의 상기 결합부와 상기 절삭날의 판면에 형성한 복수의 연결홀을 통해 동시에 관통하면서 복수의 상기 고정판과 함께 상기 절삭날들을 고정시키도록 하는 체결부재의 결합에 의해 구비되는 구성이 특징이다.In order to achieve the above object, the present invention forms a spindle coupling hole in which the main shaft is connected to the center, and the outer circumferential end is formed to be evenly divided along the main surface so as to continuously form a coupling portion having a predetermined width inclined from one end to the other end. With a fixed plate of; Each of the engaging portions of the fixed plate is formed with the same length, and the circular cutting edge of the circular shape so that the saw blades are continuously formed along the outer peripheral surface at an inclined angle to be symmetrical with each other to protrude outward from the outer peripheral end from the center of the fixed plate and; Characterized by the combination of the fastening member for fixing the cutting edges with a plurality of the fixing plate while simultaneously passing through a plurality of connecting holes formed in the coupling portion and the cutting surface of the fixed plate of the fixed plate. .
상기의 구성에서 상기 절삭날에 형성되는 톱날은 주면 단면을 따라 주면에 대해 엇각으로 비틀린 형상이며, 인접하는 양측의 톱날은 서로 대칭이 되는 각도로 연속해서 형성되도록 한다.In the above configuration, the saw blade formed on the cutting edge is twisted at a right angle with respect to the main surface along the main surface cross section, and the saw blades on both sides adjacent to each other are continuously formed at angles symmetric to each other.
또한 상기의 구성에서 상기 절삭날에 형성되는 각 톱날은 양날부가 외측으로 돌출되고, 양날부 사이는 내측으로 요입되도록 하는 형상으로 형성되도록 한다.In addition, in the above configuration, each saw blade formed on the cutting edge is to be formed in a shape such that both blades protrude outwards, and between the blades are recessed inward.
상기의 본 발명에 따른 노면 절삭 장치는 지그재그의 톱날 형상인 칼날에 의해 노면을 도려내면서 절삭날을 정역회전에 의해서 동일한 절삭 효과를 구현할 수 있도록 하므로써 절삭날의 사용 수명이 한층 연장되도록 하는 동시에 손상 또는 마모된 절삭날만을 부분적으로 교체 가능하므로 유지 관리하는데 매우 경제적인 이점이 있다.The road surface cutting apparatus according to the present invention can cut out the road surface by the saw blade-shaped blade of the zigzag while realizing the same cutting effect by the forward and reverse rotation, so that the service life of the cutting edge is further extended at the same time or damaged or Only partially worn cutting edges can be replaced, which is very economical to maintain.

상기한 본 발명에 따른 구성을 첨부된 도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Referring to the configuration according to the present invention described above in detail with reference to the accompanying drawings as follows.
도 1은 본 발명에 따른 노면 절삭 장치의 조립된 구성을 도시한 사시도이고, 도 2는 본 발명에 따른 노면 절삭 장치를 분해시킨 요부 확대 사시도이다.1 is a perspective view showing an assembled configuration of a road cutting device according to the present invention, Figure 2 is an enlarged perspective view of the main portion of the road cutting device according to the present invention.
도면을 통해 도시한 바와 같이 본 발명의 노면 절삭 장치는 크게 고정판(10)과 절삭날(20)과 체결부재(30)로서 이루어지는 구성이다.As shown through the drawings, the road surface cutting apparatus of the present invention is largely composed of a fixed plate 10, a cutting blade 20, and a fastening member 30.
본 발명의 구성에서 고정판(10)은 일정한 두께를 갖는 원형 구조이다.In the configuration of the present invention, the fixing plate 10 has a circular structure having a constant thickness.
고정판(10)에는 판면의 중앙으로 주축(11)이 결합되는 주축결합홀(12)을 형성하고, 외주연 단부는 센터로부터 주면을 따라 균등하게 구분되도록 하며, 이렇게 해서 복수로 구분되는 판면의 일정 폭을 일단에서 타단으로 경사지도록 하여 단부간 단차지는 결합부(13)를 형성한다.In the fixed plate 10 to form a main shaft coupling hole 12 to the main shaft 11 is coupled to the center of the plate surface, the outer peripheral end is to be evenly divided along the main surface from the center, so that the constant of the plate surface divided into a plurality A step-to-end step forming engagement portion 13 is made so that the width is inclined from one end to the other end.
즉 결합부(13)는 판면의 외주연부를 따라 일정폭으로 경사지게 요입되도록 하는 형상으로서, 예를 들면 결합부(13)를 도 2에서와 같이 5부분으로 나누어지게 했을 때 시계방향으로 5부분으로 나누어지는 부위는 일정한 깊이로 단차가 지도록 하는 것으로서, 이를 구체적으로 설명하면 도면에서와 같이 판면 중심으로부터 상단부로부터 72°위치까지 판면이 점차 후방으로 요입되면서 하향 경사지는 형상이 되며, 이때 72° 위치에는 경사면의 끝 부분과 시작 부분이 겹치면서 일정한 깊이로 단차지는 형상을 이루게 된다.That is, the coupling part 13 is shaped to be inclined at a predetermined width along the outer periphery of the plate surface. For example, when the coupling part 13 is divided into five parts as shown in FIG.
