건설장비의 체적가변성 기밀 실린더로드보호커버{A bulk variable anger confidential cylinder rod protection cover of construction equipment}A bulk variable anger confidential cylinder rod protection cover of construction equipment

본 고안은 건설장비의 체적가변성 기밀 실린더로드보호커버에 관한 것으로, 보다 상세하게는 실린더 외관 및 구조는 그대로 유지하고 실린더로드 헤드에서 실린더까지 체적 가변성을 가진 보호커버를 기밀 부착하여 외부 분진물질이 실린더로드에 유입되지 않도록 하여 실린더 실링 손상을 방지하고, 실린더 수축 팽창 작동에 물의가 없도록 하는 건설장비의 체적가변성 기밀 실린더로드보호커버에 관한 것이다.The present invention relates to a volume-variable hermetic cylinder rod protective cover of construction equipment, and more specifically, to maintain the appearance and structure of the cylinder intact, and to cover the cylinder with a variable volume cover from the cylinder rod head to the cylinder, The present invention relates to a volume-variable hermetic cylinder rod protective cover of construction equipment that prevents the cylinder sealing damage from being introduced into the rod and prevents the cylinder from contracting and expanding.

일반적으로 굴삭기 또는 도우저등과 같은 건설장비는 작업조건이 열악한 환경에서 주로 작업을 함에 따라 작업장에서 먼지나 흙과 같은 장비의 활동부위에 장애요인이 되는 이물질의 발생이 불가피하게 되며 이와 같은 이물질은 장비의 활동부위에 누적되는 경우가 종종 발생된다.In general, construction equipment such as excavators or dozers mainly work in an environment with poor working conditions, and thus it is inevitable to generate foreign objects that are obstacles to the active parts of equipment such as dust and dirt in the workplace. Accumulation often occurs at the active area of the equipment.

종래에는 도 1 에서와 같이 실린더로드(1)의 상측에만 단순히 보호커버(7)를 장착함으로서 실린더로드의 전체가 보호되지 않아 먼지나 흙과 같은 이물질이 실린더로드에 누적되어 실린더의 실링이 손상되고 실린더의 팽창 작동에 물의가 되는 문제가 있다.In the related art, simply attaching the protective cover 7 only to the upper side of the cylinder rod 1 as shown in FIG. 1 does not protect the entire cylinder rod, and foreign matters such as dust or dirt accumulate on the cylinder rod and damage the sealing of the cylinder. There is a problem of water in the expansion operation of the cylinder.

본 고안은 상기와 같은 종래의 결점을 해결하기 위해 안출되는 것으로, 건설장비가 지하 작업장이나 분진이 많은 지역 또는 오염지역 작업시 외부 분진물질에 실린더가 노출되지 않도록 실린더로드 헤드에서부터 실린더까지 실린더로드보호커버를 기밀 부착하여 실린더로드에 먼지나 기타 이물질이 유입하지 못하게 함으로 인해 실린더 실링의 손상을 줄여 실린더의 수축과 팽창 작동이 원활히 이루어지게 하는 건설장비의 체적가변성 기밀 실린더로드보호커버를 제공함을 목적으로 한다.The present invention is devised to solve the above-mentioned drawbacks, and the cylinder rod protection from the cylinder rod head to the cylinder so that the construction equipment is not exposed to the external dust material when working in the underground workplace, dusty areas or contaminated areas. The purpose of the present invention is to provide a volume-variable hermetic cylinder rod protective cover of construction equipment that reduces the damage of the cylinder seal by preventing the inflow of dust or other foreign substances to the cylinder rod by sealing the cover. do.

상기 목적을 달성하기 위한 본 고안은 실린더로드 헤드에서 실린더까지 피복되어 내부의 체적이 변화하지 않도록 기밀을 유지하고 실린더의 구동시 유동이 가능한 실린더로드보호커버와, 상기 실린더로드보호커버의 일측에 부착된 신축공기방과, 상기 실린더의 작동시 실린더로드보호커버 내부의 공기가 신축공기방으로 유입될 수 있도록 실린더로드보호커버와 신축공기방의 부착면에 천공된 공기유입구로 구성된다.The present invention for achieving the above object is a cylinder rod protective cover which is covered from the cylinder rod head to the cylinder to maintain the airtight so that the internal volume does not change, and is possible to flow when driving the cylinder, and attached to one side of the cylinder rod protective cover It is composed of a stretched air chamber and an air inlet perforated on the attachment surface of the cylinder rod protection cover and the expansion air chamber so that the air inside the cylinder rod protection cover can be introduced into the expansion air chamber during the operation of the cylinder.

이하 본 고안의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.Hereinafter, the configuration and the operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2 는 본 고안의 실린더로드보호커버의 부착 및 작동을 나타낸 예시도로서, 실린더로드 헤드(2)에서 실린더(3)까지 외부의 분진물질이나 기타 이물질이 실린더로드(1)의 표면에 부착되지 않도록 실린더로드보호커버(6)가 기밀하게 밀봉되어 피복되어 있고, 상기 피복된 실린더로드보호커버(6)의 실린더(3) 쪽에 신축공기방(4)이 부착되어 있으며, 상기 신축공기방(4)과 실린더로드보호커버(6)사이에는 서로를 연결해주는 공기유입구가 천공되어 있다.Figure 2 is an exemplary view showing the attachment and operation of the cylinder rod protective cover of the present invention, the external dust or other foreign matter from the cylinder rod head (2) to the cylinder (3) is not attached to the surface of the cylinder rod (1) The cylinder rod protective cover 6 is hermetically sealed and coated, and the expansion air chamber 4 is attached to the cylinder 3 side of the coated cylinder rod protection cover 6, and the expansion air chamber 4 and Between the cylinder rod protective cover 6 is air inlet for connecting to each other is perforated.

여기서, 유압에 의해 실린더로드(1)가 수축되면 실린더로드(1)를 감싸고 있던 실린더로드보호커버(6)가 오므려 들면서 실린더로드보호커버(6) 내부에 있는 공기가 공기유입구(5)를 통해 신축공기방(4)으로 유입되어 신축공기방(4)이 팽창된다.Here, when the cylinder rod 1 is contracted by hydraulic pressure, the cylinder rod protective cover 6 surrounding the cylinder rod 1 retracts and the air inside the cylinder rod protective cover 6 opens the air inlet 5. Inflow to the expansion air chamber (4) through the expansion of the expansion air chamber (4).

또한 실린더로드(1)가 팽창되면 실린더로드보호커버(6)는 오므려졌던 부분이 펴지면서 신축공기방(4) 내부에 있던 공기들이 다시 공기유입구를 통해 실린더로드보호커버 내부로 유입된다.In addition, when the cylinder rod 1 is inflated, the cylinder rod protective cover 6 is opened, and the air inside the expansion air chamber 4 is introduced again into the cylinder rod protective cover through the air inlet.

실린더로드보호커버는 실린더의 신장 수축에도 내부의 체적이 변하지 않게 실린더로드와, 실린더를 완전히 밀봉하여 기밀을 유지한다.The cylinder rod protective cover completely seals the cylinder rod and the cylinder so that the volume thereof does not change even when the cylinder is extended and contracted to maintain airtightness.

본 고안은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

상기와 같은 본 고안의 구성 및 작용에 의해 기대할 수 있는 본 고안의 효과는 실린더로드 헤드에서 실린더까지 체적이 가변되는 실린더 보호커버가 기밀하게 밀봉되어 있어 외부 분진물질이나 기타 이물질이 실린더로드 작동부에 유입되는 것을 방지하여 실린더 실링의 손상을 방지함으로서 실린더의 사용 수명을 연장할 수 있는 매우 유용한 고안이다.The effect of the present invention that can be expected by the configuration and operation of the present invention as described above is that the cylinder protective cover of the variable volume from the cylinder rod head to the cylinder is hermetically sealed, so that foreign dust or other foreign substances It is a very useful design that can prolong the service life of the cylinder by preventing the inflow of the cylinder seal.
