Abstract

The rod cover reduces the air borne noise and the structure borne noise caused by the contact between a piston and a rod of the breaker used for crushing a concrete structure or a rock. The rod cover, installed at a lower part of a front head(4), covers the rod(3) to break away the ringing noises. The bellows shaped surface is automatically shortened or expanded according to the position of the rod tip. Also, the rod cover is made of an elastic and sound absorption material.

본 발명은 건설중장비 브레이커용 로드커버에 관한 것으로 브레이커는 콘크리트 구조물이나 바위 등 단단한 물체에 충격하중을 가하여 부수하는데 사용하는 건설장비인데 이 장비는 유압 등을 이용하여 피스톤을 실린더내에서 왕복운동시키면서 로드에 에너지를 전달하게 된다.The present invention relates to a load cover for a construction equipment breaker, a breaker is a construction equipment used to attach a shock load to a hard object such as a concrete structure or rock, the equipment is a rod while reciprocating the piston in the cylinder using hydraulic pressure, etc. To deliver energy.

그리고 이 장비의 로드 끝(TIP) 부분은 단단한 타격 대상체에 접촉하면서 피스톤이 갖고 있던 에너지를 전달받아 물체를 부수거나 쪼개는 역할을 담당한다.The rod tip (TIP) of the machine is responsible for breaking or splitting the object, receiving the energy the piston had while in contact with a hard hitting object.

이와 같은 브레이커의 구조를 간략하면 제1도와 같으며 유압을 이용한 브레이커의 단면구조를 나타내는데, 도면중 부호(1)은 피스콘, (2)는 실린더, (3)은 로드, (4)는 후론트 헤드, (5)는 유압 어큐무레이터, (6)은 타격대상체이다.The structure of such a breaker is briefly shown in FIG. 1 and shows the cross-sectional structure of the breaker using hydraulic pressure. In the drawing, reference numeral 1 denotes a peace cone, 2 denotes a cylinder, 3 denotes a rod, and 4 denotes a front. The head (5) is a hydraulic accumulator, and (6) is a hitting object.

이와 같이된 브레이커는 큰 힘을 순간적으로 작용하도록 하여 단단한 물체를 부수기 때문에 커다란 충격력이 피스톤으로부터 로드를 걸쳐 다격대상체에 전달된다. 이 과정에서 피스톤과 로드 사이, 로드 팁과 물체 사이에서 충격소음이 발생한다. 피스톤과 로드 사이의 접촉에 기인한 소음은 공기발생 소음(air-borne noise)과 구조소음(structure-borne noise)의 전달과정을 거쳐 공사장 주변으로 전파하게 되어 심각한 소음공해를 유발하고 있다.This breaker breaks a hard object by causing a large force to act momentarily so that a large impact force is transmitted from the piston across the rod to the striking object. In this process, impact noise is generated between the piston and the rod and between the rod tip and the object. Noise caused by the contact between the piston and the rod propagates around the construction site through the transmission of air-borne noise and structure-borne noise, causing severe noise pollution.

본 발명은 이러한 소음을 차단시켜 공사장 부근에서의 소음공해를 예방한 것으로 그 요지를 실시예인 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.The present invention is to prevent the noise pollution in the vicinity of the construction site by blocking the noise described in detail in connection with the accompanying drawings, the gist of the embodiment as follows.

브레이커 로드(3)의 외부를 감싸게 로브커버(7)을 후론트 헤드(4)의 하단에 부착설치한 구조로 되어 있다.The lobe cover 7 is attached to the lower end of the front head 4 so as to surround the outside of the breaker rod 3.

또한 이 로드커버(7)은 벨로우즈형으로 하거나, 로드커버는 스프링 요소를 내장하거나 흡음재를 설치하는 실시예를 부가할 수 있으며 이를 상세히 설명하면 길이방향으로 신축적으로 변화될 수 있는 주름 형태를 가지며, 주름이 늘어났을 시에는 항타 대상체의 표면에 닿는 정도이고, 로드 팁이 타격 대상체안으로 침투한 경우에는 길이가 자동적으로 줄어들 수 있는 기능을 갖는 것과 또 로드커버에 스프링요소(도시없음) 내장시켜 길이 변화가 가능하며, 그 재질을 흡음재를 사용한 것을 포함시킨다.In addition, the rod cover 7 may be bellows type, or the rod cover may include an embodiment in which a spring element is built in or a sound absorbing material is installed. When the wrinkles are stretched, they reach the surface of the driving object, and when the rod tip penetrates into the hitting object, the length is automatically reduced, and a spring element (not shown) is built into the road cover. It is possible to change the material, including the use of sound absorbing material.

이와 같이된 본 발명은 앞서 기술한 소음의 전달 경로중 로드와 후론트 헤드 사이의 간극으로 나오는 소음과, 로드의 울림소음(ringing noise), 그리고 로드 팁과 물체와의 충격 접촉에 의하여 발생하는 소음을 감소시키는 역할을 하며, 특히 본 발명은 길이방향(로드축 방향)으로 신축성이 있는 후론트 헤드의 하단부와 물체 사이의 공간에 걸쳐 분포된 형태를 취하면서, 이 공간에서 발생하는 소음을 감소시키게 됨으로 특히 도심에서 시공하는 공사장에서 필수적으로 설치하게 하여 소음 공해를 예방할 수 있게 한 것이다.As described above, the present invention deals with the noise generated by the gap between the rod and the front head, the ringing noise of the rod, and the noise generated by the impact between the rod tip and the object. In particular, the present invention takes the form distributed over the space between the lower end of the flexible front head and the object in the longitudinal direction (rod axis direction), while reducing the noise generated in this space. It is necessary to install at the construction site in the city center to prevent noise pollution.
