Definitions

  • the present invention relates to a hydraulic breaker equipped with a direct-coupled lubricant automatic supply block.
  • Hydraulic breakers are equipment that is mounted on construction equipment such as excavators and lifts or lowers the piston, which is a lifting member, by a power source such as hydraulic pressure and uses the striking force generated through this to crush objects such as rock and concrete.
  • the hydraulic breaker injects lubricant into the front head surrounding the chisel to prevent wear due to friction of the chisel that is struck as the piston rises and falls.
  • Lubricant can be injected manually by the operator. However, in this case, there is a problem that the efficiency of hydraulic breaker work is reduced because the operator must periodically inject lubricant. In addition, if the timing of lubricating oil injection is missed, severe wear may occur inside the front head, shortening the lifespan of the piston and chisel.

Description

직결식 윤활유 자동 공급 블록이 구비된 유압 브레이커Hydraulic breaker with direct-coupled lubricant automatic supply block
본 발명은 직결식 윤활유 자동 공급 블록이 구비된 유압 브레이커에 관한 것이다.The present invention relates to a hydraulic breaker equipped with a direct-coupled lubricant automatic supply block.
유압 브레이커는 굴삭기 등의 건설장비에 장착되어 유압 등 동력원에 의해 승하강 부재인 피스톤을 승강 또는 하강시키고 이를 통해 발생되는 타격력을 이용하여 암반, 콘크리트 등 목적물을 파쇄하는 장비이다.Hydraulic breakers are equipment that is mounted on construction equipment such as excavators and lifts or lowers the piston, which is a lifting member, by a power source such as hydraulic pressure and uses the striking force generated through this to crush objects such as rock and concrete.
유압 브레이커는 피스톤의 승하강에 따라 타격되는 치즐의 마찰에 따른 마모를 방지하기 위하여 치즐을 감싸는 프론트 헤드 내부로 윤활유를 주입한다.The hydraulic breaker injects lubricant into the front head surrounding the chisel to prevent wear due to friction of the chisel that is struck as the piston rises and falls.
윤활유는 작업자에 의해 수작업으로 주입될 수 있다. 그러나, 이 경우, 작업자가 주기적으로 윤활유 주입 작업을 수행해야 하므로 유압 브레이커 작업의 능률을 저하시키는 문제가 있다. 또한, 윤활유 주입 시기를 놓칠 경우, 프론트 헤드 내부에서 심한 마모가 발생되어 피스톤 및 치즐의 수명을 단축시키는 문제가 야기될 수 있다. Lubricant can be injected manually by the operator. However, in this case, there is a problem that the efficiency of hydraulic breaker work is reduced because the operator must periodically inject lubricant. In addition, if the timing of lubricating oil injection is missed, severe wear may occur inside the front head, shortening the lifespan of the piston and chisel.
이와 같은 문제를 해결하기 위해 윤활유를 자동으로 공급하는 유압 브레이커에 대한 기술이 개시된다.To solve this problem, technology for a hydraulic breaker that automatically supplies lubricating oil is disclosed.
유압 브레이커는, 별도의 부품으로 마련된 자동윤활장치가 외부에 노출되는 형태로 장착된다. 유압 브레이커는 노출 구조로 자동윤활장치를 구비한 상태에서, 자동윤활장치 내부로 작동유를 유입시키는 유압 라인과, 자동윤활장치의 윤활유를 굴삭기로 유출하는 유출 라인이 호스 형태로 구비된다. Hydraulic breakers are equipped with an automatic lubrication device provided as a separate part that is exposed to the outside. The hydraulic breaker has an exposed structure and is equipped with an automatic lubricating device, and is provided with a hydraulic line that flows hydraulic oil into the automatic lubricating device and an outflow line that drains the lubricating oil from the automatic lubricating device to the excavator in the form of a hose.
그런데, 이 경우, 자동윤활장치 및 호스로 구비된 유압, 유출 라인이 모두 유압 브레이커의 외측에 노출 구조로 구비되어 파쇄 작업 중 암반이나 콘크리트 파편에 의해 쉽게 파손되는 문제가 발생할 수 있다.However, in this case, the automatic lubrication device and the hydraulic and outflow lines provided with hoses are all exposed to the outside of the hydraulic breaker, so there may be a problem of being easily damaged by rock or concrete fragments during crushing work.
자동윤활장치의 외부 장착 구조의 문제점을 해결하기 위해 유압 브레이커의 내부에 자동윤활장치를 구비하는 기술이 개시된다.In order to solve the problem of the external mounting structure of the automatic lubrication device, a technology for providing an automatic lubrication device inside a hydraulic breaker is disclosed.
그런데, 내부에 자동윤활장치를 구비할 경우, 윤활유 및 작동유를 유입시키기 위한 유로를 메인 바디에 형성해야 하는데, 대형 유압 브레이커의 경우, 메인 바디 내부에 유로를 형성하는 것이 상대적으로 어렵다.However, when an automatic lubrication device is provided inside, a flow path for introducing lubricating oil and hydraulic oil must be formed in the main body. However, in the case of a large hydraulic breaker, it is relatively difficult to form a flow path inside the main body.
이뿐만 아니라, 자동윤활장치를 내장형으로 구비하는 구조의 경우, 자동윤활장치가 고장나면 유압 브레이커의 작동을 정지한 상태에서 유압 브레이커를 분해하여 교체 또는 수리 작업을 수행해야 한다는 점에서 번거로움이 있다. 또한, 교체 또는 수리 작업을 수행하는 동안 유압 브레이커의 작업을 수행할 수 없으므로 유압 브레이커를 이용한 건설 현장 작업 전체의 효율을 저하시키는 문제를 야기할 수 있다.In addition, in the case of a structure equipped with a built-in automatic lubrication device, if the automatic lubrication device breaks down, it is inconvenient in that the hydraulic breaker must be disassembled and replaced or repaired while the hydraulic breaker is stopped. . In addition, since the work of the hydraulic breaker cannot be performed while replacement or repair work is performed, this may cause a problem that reduces the overall efficiency of construction site work using a hydraulic breaker.

작동유가 제1챔버(CB1)로 유입되면, 로드(RD)의 폭 방향(±x방향) 일측(-x방향)이 작동유에 의해 가압되어 로드(RD)의 단부(RE)가 타측(+x방향, 도 6a, 도 6b에서 우측)으로 이동한다. 로드(RD)의 단부(RE)는 상기 타측으로 이동하여 윤활유 피스톤(PS)의 제2챔버(CB2)로서 기능하는 윤활유 챔버(LC)에 위치한다.When hydraulic oil flows into the first chamber (CB1), one side (-x direction) in the width direction (±x direction) of the rod (RD) is pressurized by the hydraulic oil, and the end (RE) of the rod (RD) is pressed to the other side (+x direction). direction, to the right in Figures 6a and 6b). The end RE of the rod RD moves to the other side and is located in the lubricant chamber LC, which functions as the second chamber CB2 of the lubricant piston PS.
윤활유 챔버(LC)에 충진된 윤활유는 윤활유 챔버(LC)에 위치한 로드(RD)의 단부에 의해 밀려나면서 체크 밸브(CK)의 볼(BA)을 폭 방향(±x방향) 타측(+x방향, 도 6a, 도 6b에서 우측)으로 이동시킨다. 이에 따라 체크 밸브(CK)가 개방되고, 윤활유는 윤활유 송출 라인(TL)으로 유동하여 윤활유 주입구(LI)를 통과하여 윤활유 공급 라인(SL)으로 유동하여 메인 바디(11)로 유입된다. 메인 바디(11)로 유입된 윤활유는 치즐(16)의 외면과 프론트 헤드(15)의 내면 사이로 공급되어 치즐(16)의 왕복 운동이 효율적으로 이루어지도록 한다.The lubricant filled in the lubricant chamber (LC) is pushed by the end of the rod (RD) located in the lubricant chamber (LC) and moves the ball (BA) of the check valve (CK) in the width direction (±x direction) and the other side (+x direction). , move to the right in Figures 6a and 6b. Accordingly, the check valve (CK) is opened, and the lubricant flows to the lubricant delivery line (TL), passes through the lubricant inlet (LI), flows to the lubricant supply line (SL), and flows into the main body (11). The lubricant flowing into the main body 11 is supplied between the outer surface of the chisel 16 and the inner surface of the front head 15 to ensure the reciprocating motion of the chisel 16 is efficient.
도 6b를 참조하면, 본 발명의 유압 브레이커(10)는 윤활유 자동 공급 블록(BK)의 상부에 에어벤트(AB)를 추가적으로 연결한다. 에어벤트(AB)는 윤활유 자동 공급 블록(BK)의 상부를 관통하여 윤활유 챔버(LC)측에 연결되도록 구비된다. 본 발명의 유압 브레이커(10)는 에어벤트(AB)를 통해 윤활유 카트리지(CT)와 윤활유 챔버(LC) 사이에 발생한 에어를 제거한다. 이로 인해 윤활유 카트리지(CT)로부터 윤활유 챔버(LC)로 윤활유가 유동하는 과정에서 에어가 발생하는 문제를 방지할 수 있다. Referring to Figure 6b, the hydraulic breaker 10 of the present invention additionally connects an air vent (AB) to the upper part of the lubricant automatic supply block (BK). The air vent (AB) is provided to penetrate the upper part of the lubricant automatic supply block (BK) and be connected to the lubricant chamber (LC).

한편, 굴삭기의 유압 펌프의 가동이 중단됨에 따라 본 발명의 유압 브레이커(10)의 가동이 중단될 수 있다. 이 경우, 작동유는 제1챔버(CB1)로 더 이상 유입되지 않고, 로드(RD)를 가압하는 가압력이 발생하지 않는다. 이에 따라 제1챔버(CB1) 내에 구비된 탄성 부재(SP)의 탄성 복원력에 의해 폭 방향(±x방향) 타측(+x방향, 도 5, 도 6a 및 도 6b의 우측)으로 이동하였던 로드(RD)의 단부가 폭 방향(±x방향) 일측(-x방향, 도 5, 도 6a 및 도 6b의 좌측)으로 이동하면서 원위치된다.Meanwhile, as the operation of the hydraulic pump of the excavator is stopped, the operation of the hydraulic breaker 10 of the present invention may be stopped. In this case, the hydraulic oil no longer flows into the first chamber CB1, and no pressing force is generated to press the rod RD. Accordingly, the rod that moved to the other side (+x direction, right side of FIGS. 5, 6A and 6B) in the width direction (±x direction) due to the elastic restoring force of the elastic member (SP) provided in the first chamber (CB1) The end of RD) is moved to one side (-x direction, left side of FIGS. 5, 6A and 6B) in the width direction (±x direction) and returned to its original position.

The inner space is expanded by increasing the diameter of the telescopic movable parts 32a and 32b.
탄성 커버(27)는 신축 이동부(32)를 통해 메인 바디(11) 및 브라켓(20)이 상대 이동할 때, 상기 상대 이동을 수용하면서 카트리지 수용구멍(23)을 완전히 밀폐하는 기능을 수행할 수 있다.The elastic cover 27 can perform the function of completely sealing the cartridge receiving hole 23 while accommodating the relative movement when the main body 11 and the bracket 20 move relative to each other through the elastic moving part 32. there is.
구체적으로, 메인 바디(11)와 브라켓(20)은 별체 거동 가능하게 구비되고 전, 후, 상, 하, 좌, 우 방향 중 적어도 하나로 상대 이동한다. 메인 바디(11)와 브라켓(20)이 상대 이동하며 별체 거동하는 구조에서, 탄성 커버(27)는, 브라켓(20)에 구비되어 메인 바디(11)에 장착된 윤활유 자동 공급 블록(BK)에 결합된 윤활유 카트리지(CT)를 통과시킨다. 이에 따라 메인 바디(11) 및 브라켓(20) 중 적어도 하나의 상대 이동 시 윤활유 카트리지(CT)는 탄성 커버(27)를 관통하는 상태에서 상기 상대 이동에 따라 변위한다.Specifically, the main body 11 and the bracket 20 are provided to be able to move as separate bodies and move relative to each other in at least one of the forward, backward, up, down, left, and right directions. In a structure in which the main body 11 and the bracket 20 move relative to each other and act as separate bodies, the elastic cover 27 is provided on the bracket 20 and attached to the lubricant automatic supply block (BK) mounted on the main body 11. Pass the combined lubricant cartridge (CT). Accordingly, when at least one of the main body 11 and the bracket 20 moves relative to each other, the lubricant cartridge CT penetrates the elastic cover 27 and is displaced according to the relative movement.
이 때, 탄성 커버(27)는, 밀착 고정부(30)에서 윤활유 카트리지(CT)를 고정시킨 상태로 메인 바디(11) 및 브라켓(20) 중 적어도 하나의 상대 이동에 따라 신축 이동부(32)에서 탄성 변형이 이루어지도록 한다. 신축 이동부(32)는 내측에 확장된 공간을 통해 윤활유 카트리지(CT)와 접촉되지 않은 상태로 외측면의 주름진 형태에 의해 상기 상대 이동에 따라 전, 후, 상, 하, 좌, 우 방향 중 적어도 하나로 쉽게 신축한다. At this time, the elastic cover 27 is expanded and contracted according to the relative movement of at least one of the main body 11 and the bracket 20 while the lubricant cartridge (CT) is fixed in the close fixing part 30. ) so that elastic deformation occurs. The elastic moving part 32 moves in the forward, backward, up, down, left, and right directions according to the relative movement due to the wrinkled shape of the outer surface without being in contact with the lubricant cartridge (CT) through the expanded space on the inside. Easily rebuilt with at least one piece.
이로 인해, 탄성 커버(27)는, 메인 바디(11) 및 브라켓(20) 중 적어도 하나의 상대 이동이 발생하면 신축 이동부(32)가 신축하면서 상기 상대 이동에 따른 메인 바디(11) 및 브라켓(20) 중 적어도 하나의 변위를 수용하고, 밀폐부(31)가 카트리지 수용구멍(23)을 완전히 밀폐하는 상태는 유지할 수 있다. 다시 말해, 탄성 커버(27)는 신축 이동부(32)를 구비함으로써 메인 바디(11) 및 브라켓(20) 중 적어도 하나의 상대 이동에 의해 카트리지 수용구멍(23)으로부터 이탈되는 문제가 방지된다. 이로 인해 카트리지 수용구멍(23)을 통해 파편이나 이물질이 메인 바디를 구비하는 공간으로 유입되는 문제가 차단된다. Due to this, when the relative movement of at least one of the main body 11 and the bracket 20 occurs, the elastic cover 27 expands and contracts, and the main body 11 and the bracket 20 according to the relative movement. Displacement of at least one of (20) can be accommodated, and the state in which the sealing portion 31 completely seals the cartridge receiving hole 23 can be maintained. In other words, the elastic cover 27 is provided with an elastic moving part 32 to prevent the elastic cover 27 from being separated from the cartridge receiving hole 23 due to relative movement of at least one of the main body 11 and the bracket 20. This prevents debris or foreign matter from flowing into the space containing the main body through the cartridge receiving hole 23.
또한, 탄성 커버(27)는 고무와 같은 탄성 재질로 이루어지므로 밀착 고정부(30)에 윤활유 카트리지(CT)를 고정한 상태로 신축 이동부(32)에서 탄성 변형이 발생하더라도 윤활유 카트리지(CT)의 파손이 방지된다.In addition, the elastic cover 27 is made of an elastic material such as rubber, so even if elastic deformation occurs in the elastic moving part 32 while the lubricant cartridge (CT) is fixed to the tight fixing part 30, the lubricant cartridge (CT) Damage is prevented.
이뿐만 아니라 탄성 커버(27)는 메인 바디(11) 및 브라켓(20) 중 적어도 하나의 상대 이동이 발생하더라도 카트리지 수용구멍(23)을 완전히 밀폐하므로 메인 바디(11)에서 발생하는 소음이 외부로 새어나오는 것을 방지할 수 있다. 이로 인해 본 발명의 유압 브레이커(10)는 작업 시 발생하는 소음이 최소화될 수 있다.In addition, the elastic cover 27 completely seals the cartridge receiving hole 23 even if at least one of the main body 11 and the bracket 20 moves relative to each other, so that noise generated from the main body 11 is not transmitted to the outside. It can prevent leakage. Because of this, the hydraulic breaker 10 of the present invention can minimize noise generated during operation.
본 발명의 유압 브레이커(10)는 잔량 확인이 쉬운 윤활유 카트리지(CT)를 구비하여 윤활유 카트리지(CT)의 주기적인 교체가 보다 효과적으로 이루어지도록 한다.The hydraulic breaker 10 of the present invention is equipped with a lubricant cartridge (CT) whose remaining amount can be easily checked, allowing periodic replacement of the lubricant cartridge (CT) more effectively.
도 10은 잔량 확인이 쉬운 윤활유 카트리지(CT)의 측단면도이다.Figure 10 is a side cross-sectional view of a lubricant cartridge (CT) that makes it easy to check the remaining amount.
도 10을 참조하면, 윤활유 카트리지(CT)는 반투명 재질의 용기(100)와, 용기(100) 내부의 윤활유 잔량에 따라 이동 가능한 불투명 재질의 슬라이더(100c) 및 용기(100) 외면에 구비된 지시선(100d)을 포함한다.Referring to FIG. 10, the lubricant cartridge (CT) includes a container 100 made of a translucent material, a slider 100c made of an opaque material that can be moved according to the remaining amount of lubricant inside the container 100, and an indicator line provided on the outer surface of the container 100. Includes (100d).
윤활유 카트리지(CT)는 용기(100)의 일측부에 윤활유 주입 구멍(100a)을 구비한다. 용기(100)의 일단은 윤활유 주입 구멍(100a)에 의해 개구된다. 용기(100)의 타단은 바닥부(100b)에 의해 폐쇄된다.The lubricant cartridge (CT) has a lubricant injection hole (100a) on one side of the container (100). One end of the container 100 is opened by a lubricant injection hole 100a. The other end of the container 100 is closed by the bottom 100b.
윤활유 카트리지(CT)는 윤활유 주입 구멍(100a)을 구비하는 일측부를 돌출되게 구비한다. 윤활유 카트리지(CT)는 윤활유 주입 구멍(100a)을 포함한 용기(100)의 일측부가 윤활유 자동 공급 블록(BK)의 결합부(CN)로 삽입되어 상기 블록(BK)에 교체 가능하게 결합된다.The lubricating oil cartridge (CT) has a protruding one side portion having a lubricating oil injection hole (100a). The lubricant cartridge (CT) is replaceably coupled to the block (BK) by inserting one side of the container (100) including the lubricant injection hole (100a) into the coupling portion (CN) of the lubricant automatic supply block (BK).
윤활유 카트리지(CT)는 윤활유 주입 구멍(100a)을 포함한 용기(100)의 일측부가 윤활유 자동 공급 블록(BK)에 삽입되어 외부로 노출되지 않고, 바닥부(100b)를 포함하는 나머지 일부가 상기 블록(BK)의 외측에 위치하면서 노출된다.In the lubricant cartridge (CT), one side of the container 100, including the lubricant injection hole 100a, is inserted into the lubricant automatic supply block (BK) and is not exposed to the outside, and the remaining part, including the bottom 100b, is inserted into the lubricant automatic supply block (BK). It is exposed and located on the outside of (BK).
윤활유 카트리지(CT)는 외면에 지시선(100d)을 구비한다. The lubricant cartridge (CT) has an indicator line (100d) on its outer surface.
지시선(100d)은 부착형 라인으로 구비되어 용기(100)의 외면에 탈착 가능하게 구비될 수 있다. 이와는 달리, 지시선(100d)은 부착형 라인으로 구비되지 않고 용기(100) 제조시 용기(100)에 인쇄되어 표시되어 구비될 수도 있다.The indicator line 100d may be provided as an attachable line and may be detachably provided on the outer surface of the container 100. In contrast, the indicator line 100d may not be provided as an attached line, but may be printed and displayed on the container 100 when manufacturing the container 100.
윤활유 카트리지(CT)는, 용기(100)의 외면에 부착형 라인으로 구비되는 지시선(100d)을 구비한다.The lubricating oil cartridge (CT) is provided with an indicator line (100d) provided as an attachable line on the outer surface of the container (100).
일 예로서, 지시선(100d)은 윤활유 카트리지(CT)를 3등분하여 윤활유 주입 구멍(100a)측에 가까운 3분의 2지점에 구비될 수 있다. As an example, the indicator line 100d may be provided at a two-thirds point close to the lubricant injection hole 100a by dividing the lubricant cartridge CT into three parts.
보다 구체적으로, 윤활유 카트리지(CT)는 바닥부(100b)로부터 3분의 1지점, 3분의 1지점으로부터 윤활유 주입 구멍(100a) 방향으로 위치하는 3분의 2지점, 윤활유 주입 구멍(100a)의 개구가 위치하는 3분의 3지점으로 3등분될 수 있다.More specifically, the lubricant cartridge (CT) is located at a one-third point from the bottom part (100b), at a two-thirds point located from the one-third point toward the lubricant injection hole (100a), and at a lubricant injection hole (100a). It can be divided into three parts at three-thirds of the points where the opening is located.
윤활유 자동 공급 블록(BK)과의 결합 상태에서, 윤활유 카트리지(CT)는 3분의 2지점과 3분의 3지점 사이에 위치하는 영역이 윤활유 자동 공급 블록(BK)의 결합부(CN)로 삽입될 수 있다. 윤활유 카트리지(CT)는 결합부(CN)로 삽입되는 영역과 대응되되 윤활유가 충진되는 용기(100)의 외면에 지시선(100d)을 구비할 수 있다. In the combined state with the lubricant automatic supply block (BK), the area located between the two-thirds and three-thirds points of the lubricant cartridge (CT) is connected to the coupling portion (CN) of the lubricant automatic supply block (BK). can be inserted. The lubricant cartridge (CT) may be provided with an indicator line (100d) on the outer surface of the container (100) filled with lubricant, corresponding to the area inserted into the coupling portion (CN).
한편, 지시선(100d)은 도 9 및 도 10에 도시된 위치보다 윤활유 주입 구멍(100a)측에 가까운 위치에 구비될 수 있다. 이 때, 지시선(100d)은, 바람직하게는, 상대적으로 윤활유 주입 구멍(100a)측에 가까운 위치이면서 용기(100) 내의 윤활유가 충진되는 영역과 대응되는 외면에 구비될 수 있다. 다시 말해, 지시선(100d)은, 상대적으로 윤활유 주입 구멍(100a)측에 가까운 위치이면서 슬라이더(100c)의 이동 범위 내에 포함되는 용기(100)의 외면에 구비될 수 있다.Meanwhile, the indicator line 100d may be provided at a position closer to the lubricant injection hole 100a than the position shown in FIGS. 9 and 10. At this time, the indicator line 100d is preferably located relatively close to the lubricant injection hole 100a and may be provided on the outer surface corresponding to the area filled with lubricant in the container 100. In other words, the indicator line 100d may be provided on the outer surface of the container 100 at a position relatively close to the lubricant injection hole 100a and within the moving range of the slider 100c.
이에 따라 지시선(100d)은 윤활유 카트리지(CT)와 윤활유 자동 공급 블록(BK)과의 결합 상태에서 외측으로 노출되지 않는다.Accordingly, the indicator line 100d is not exposed to the outside when the lubricant cartridge (CT) and the lubricant automatic supply block (BK) are combined.
윤활유 카트리지(CT)가 윤활유 자동 공급 블록(BK)에 장착된 상태에서 윤활유가 윤활유 챔버(LC)로 흡입될 경우, 바닥부(100b)측에 가깝게 위치하는 슬라이더(100c)가 윤활유 흡입량에 따라 점차적으로 윤활유 주입 구멍(100a)측으로 이동한다. 슬라이더(100c)는 도 10에 도시된 바와 같이 일 예로서 바닥부 및 바닥부 양측에서 일방향으로 연장되는 벽부를 포함하는 형태로 구비될 수 있고, 바닥부만을 포함하는 형태로 구비될 수도 있다. 슬라이더(100c)는 바닥부 및 벽부를 포함하는 형태일 경우, 바람직하게는, 벽부의 연장 길이를 상대적으로 작게 구비할 수 있다. 이는 슬라이더(100c)가 바닥부 및 벽부를 포함하는 형태로 구비되어 윤활유 주입 구멍(100a)측에 최대한 가깝게 이동하였을 때 벽부의 연장 길이에 의해 지시선(100d)이 가려지는 문제를 방지하기 위함이다.When lubricant is sucked into the lubricant chamber (LC) with the lubricant cartridge (CT) mounted on the lubricant automatic supply block (BK), the slider (100c) located close to the bottom (100b) gradually moves according to the amount of lubricant sucked. It moves toward the lubricant injection hole (100a). As shown in FIG. 10 , for example, the slider 100c may be provided in a form that includes a bottom and a wall extending in one direction from both sides of the bottom, or may be provided in a form that includes only the bottom. When the slider 100c has a shape including a bottom portion and a wall portion, the extended length of the wall portion may preferably be relatively small. This is to prevent the problem of the indicator line 100d being obscured by the extended length of the wall portion when the slider 100c is provided in a form including a bottom portion and a wall portion and is moved as close as possible to the lubricant injection hole 100a.
슬라이더(100c)는 용기(100) 내부에 충진된 윤활유량이 감소되면서 윤활유 주입 구멍(100a)측으로 점차적으로 이동하여 결합부(CN)에 삽입되는 영역에 구비되어 외측으로 노출되지 않는 지시선(100d)을 지난다. 슬라이더(100c)가 지시선(100d)을 지나면, 지시선(100d)과 대응되는 용기(100)의 내부 영역에 더 이상 윤활유가 존재하지 않게 되면서 바닥부(100b)측의 외측에서 지시선(100d)이 보이게 된다. 이를 통해 본 발명의 유압 브레이커(10)는 윤활유 카트리지(CT)의 잔량을 쉽게 확인할 수 있다.As the amount of lubricating oil filled inside the container 100 decreases, the slider 100c gradually moves toward the lubricating oil injection hole 100a, forming an indicator line 100d that is provided in the area inserted into the coupling portion CN and is not exposed to the outside. It passes. When the slider 100c passes the leader line 100d, lubricant no longer exists in the inner area of the container 100 corresponding to the leader line 100d, and the leader line 100d becomes visible from the outside of the bottom 100b. do. Through this, the hydraulic breaker 10 of the present invention can easily check the remaining amount of the lubricant cartridge (CT).
윤활유 카트리지(CT)는 윤활유 주입 구멍(100a)을 포함하는 일측부가 윤활유 자동 공급 블록(BK)의 결합부(CN)에 삽입되고, 나머지 일부가 외측으로 노출되는 형태로 결합된다. 따라서, 용기(100) 내부에 충진된 윤활유가 감소되어 결합부(CN)에 삽입되는 일측부에 포함된 용기(100)의 적어도 일부 영역에만 윤활유가 잔존할 경우, 윤할유 카트리지(CT)의 윤활유 잔량을 확인하기가 어렵다.The lubricant cartridge (CT) is coupled in such a way that one side including the lubricant injection hole (100a) is inserted into the coupling portion (CN) of the lubricant automatic supply block (BK), and the remaining part is exposed to the outside. Therefore, when the lubricant filled inside the container 100 is reduced and the lubricant remains only in at least a partial area of the container 100 included in one side inserted into the coupling portion CN, the lubricant in the lubricant cartridge CT It is difficult to check the remaining amount.
하지만, 본 발명의 유압 브레이커(10)는 윤활유 카트리지(CT)에 지시선(100d)을 구비한다. 지시선(100d)은, 바람직하게는, 상대적으로 윤활유 주입 구멍(100a)과 가까운 위치에 구비되므로 결합부(CN) 내측으로 삽입되는 윤활유 카트리지(100)의 일측부에 구비된다.However, the hydraulic breaker 10 of the present invention is provided with an indicator line 100d on the lubricating oil cartridge CT. The indicator line 100d is preferably provided at a position relatively close to the lubricant injection hole 100a and is therefore provided on one side of the lubricant cartridge 100 inserted into the coupling portion CN.
이에 따라, 슬라이더(100c)가 점차적으로 윤활유 주입 구멍(100a)측으로 이동하여 지시선(100d)을 지나면, 브라켓(20) 외측에서 바닥부(100b)를 통해 용기(100) 내부를 들여다보았을 때, 지시선(100d)이 보이게 된다. 이로 인해 본 발명의 유압 브레이커(10)는, 탄성 커버(27)를 통해 윤활유 카트리지(CT)의 바닥부(100b)를 포함하는 일측부를 돌출시켜 노출하는 구조에서 윤활유 카트리지(CT)의 잔량을 외부에서 육안으로 쉽게 확인하는 것이 가능하다.Accordingly, when the slider 100c gradually moves toward the lubricant injection hole 100a and passes the indicator line 100d, when looking into the inside of the container 100 through the bottom 100b from the outside of the bracket 20, the indicator line (100d) becomes visible. For this reason, the hydraulic breaker 10 of the present invention has a structure in which one side including the bottom 100b of the lubricant cartridge CT is protruded and exposed through the elastic cover 27, so that the remaining amount of the lubricant cartridge CT is exposed to the outside. It is possible to easily check with the naked eye.
이처럼 본 발명의 유압 브레이커(10)는 브라켓(20)의 외측에서 육안으로 쉽게 잔량 확인이 가능한 윤활유 카트리지(CT)를 윤활유 자동 공급 블록(BK)에 장착함으로써 윤활유 카트리지(CT)의 교체 시기를 놓쳐서 파쇄 작업을 지연시키는 문제를 방지할 수 있다.In this way, the hydraulic breaker 10 of the present invention is equipped with a lubricant cartridge (CT) whose remaining amount can be easily checked with the naked eye from the outside of the bracket 20 to the lubricant automatic supply block (BK), thereby preventing the replacement period of the lubricant cartridge (CT) from being missed. Problems that delay the shredding operation can be prevented.
