Description

유압 브레이커용 윤활유 카트리지Lubricant cartridges for hydraulic breakers
본 발명은 유압 브레이커에 장착되는 유압 브레이커용 윤활유 카트리지에 관한 것이다.The present invention relates to a lubricant cartridge for a hydraulic breaker mounted on a hydraulic breaker.
유압 브레이커는 굴삭기 등의 건설장비에 장착되어 유압 등 동력원에 의해 승하강 부재인 피스톤을 상승 또는 하강시키고 이를 통해 발생되는 타격력을 이용하여 암반, 콘트리트 등 목적물을 파쇄하는 장비이다.Hydraulic breakers are equipment that is mounted on construction equipment such as excavators and raises 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 윤활유가 주입된다. 윤활유는 유압 브레이커의 윤활유 자동 공급 블록(EP)에 장착된 윤활유 카트리지(CT')를 통해 유압 브레이커의 내부로 주입된다.In the hydraulic breaker, lubricating oil is injected 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. Lubricating oil is injected into the interior of the hydraulic breaker through a lubricating oil cartridge (CT') mounted on the automatic lubricating oil supply block (EP) of the hydraulic breaker.
윤활유 카트리지(CT')는 용기(CN)에 일정 용량의 윤활유(LB)가 충진된 상태로 윤활유 자동 공급 블록(EP)에 장착되고, 용기에 충진된 윤활유(LB)가 모두 소진되면 작업자에 의해 새것으로 교체된다.The lubricant cartridge (CT') is installed in the lubricant automatic supply block (EP) with a certain amount of lubricant oil (LB) filled in the container (CN), and is activated by the operator when all the lubricant oil (LB) filled in the container is used up. replaced with a new one.
도 1은 주입구(ET)를 포함하는 용기(CN)의 목부(ST)를 통해 윤활유 자동 공급 블록(EP)에 장착된 종래의 윤활유 카트리지(CT')를 개략적으로 도시한 도이다.Figure 1 schematically shows a conventional lubricant cartridge (CT') mounted on a lubricant automatic supply block (EP) through a neck (ST) of a container (CN) including an injection port (ET).
윤활유 카트리지(CT')는 유압 브레이커(10)에 윤활유(LB)를 주입하는 주입구(ET)를 포함하는 목부(ST) 및 목부(ST)와 연통되는 충진부(FP)로 구성되는 용기(CN)와, 충진부(FP) 내부에 구비되어 용기(CN)에 충진된 윤활유(LB)의 잔량에 따라 바닥부(GP)에서부터 주입구(ET)측으로 슬라이드 이동하는 슬라이더(SL)를 포함한다.The lubricant cartridge (CT') is a container (CN) consisting of a neck part (ST) including an injection port (ET) for injecting lubricant oil (LB) into the hydraulic breaker 10 and a filling part (FP) in communication with the neck part (ST). ) and a slider (SL) provided inside the filling part (FP) and sliding from the bottom part (GP) to the injection port (ET) according to the remaining amount of lubricant oil (LB) filled in the container (CN).
윤활유 카트리지(CT')는 결합 부위(CS)의 길이의 치수가 상대적으로 작은 윤활유 자동 공급 블록(EP)에 목부(ST)를 삽입하여 윤활유 자동 공급 블록(EP)에 결합될 수 있다. 도 1을 참조하면, 윤활유 카트리지(CT')는 목부(ST)만이 윤활유 자동 공급 블록(EP) 내부로 삽입되고 충진부(FP)가 전체적으로 윤활유 자동 공급 블록(EP)의 외부에 위치하는 형태로 윤활유 자동 공급 블록(EP)에 장착될 수 있다.The lubricant cartridge (CT') can be coupled to the lubricant automatic supply block (EP) by inserting the neck portion (ST) into the lubricant automatic supply block (EP) whose length of the coupling portion (CS) is relatively small. Referring to FIG. 1, the lubricant cartridge (CT') has only the neck portion (ST) inserted into the lubricant automatic supply block (EP) and the filling portion (FP) is entirely located outside the lubricant automatic supply block (EP). It can be mounted on a lubricant automatic supply block (EP).
그런데, 윤활유 카트리지(CT')의 목부(ST)를 통해 윤활유 자동 공급 블록(EP)에 결합되는 구조에서, 충진부(FP)가 외부에 노출되므로 광투광성 재질의 용기(CN)의 측면을 통해 윤활유(LB) 잔량을 확인하는 것은 쉬울 수 있으나, 유압 브레이커(10)의 파쇄물의 파편이 튀면서 충진부(FP)가 파손될 위험성이 높다.However, in the structure where the lubricant cartridge (CT') is coupled to the lubricant automatic supply block (EP) through the neck (ST), the filling portion (FP) is exposed to the outside, so it is exposed to the outside through the side of the container (CN) made of a light-transmitting material. Although it may be easy to check the remaining amount of lubricating oil (LB), there is a high risk that the filling part (FP) will be damaged as fragments of the hydraulic breaker (10) fly out.
이에 따라 윤활유 카트리지(CT')의 파손 위험성을 최소화하기 위해 결합 부위(CS)의 길이의 치수가 큰 윤활유 자동 공급 블록(EP)에 윤활유 카트리지(CT')를 장착하는 구조가 제안되었다. 이로 인해 윤활유 카트리지(CT')는 윤활유 자동 공급 블록(EP)에 깊게 삽입되며 윤활유 카트리지(CT')의 단부의 일부가 윤활유 자동 공급 블록(EP)로부터 돌출되어 노출된다.Accordingly, in order to minimize the risk of damage to the lubricant cartridge (CT'), a structure was proposed in which the lubricant cartridge (CT') is mounted on the lubricant automatic supply block (EP) with a large length of the coupling portion (CS). As a result, the lubricant cartridge (CT') is deeply inserted into the lubricant automatic supply block (EP), and a portion of the end of the lubricant cartridge (CT') protrudes from the lubricant automatic supply block (EP) and is exposed.
도 2는 결합 부위(CS)의 길이의 치수가 상대적으로 큰 윤활유 자동 공급 블록(EP)에 종래의 윤활유 카트리지(CT')를 장착한 상태를 도시한 도이다.FIG. 2 is a diagram illustrating a state in which a conventional lubricant cartridge (CT') is mounted on an automatic lubricant supply block (EP) in which the length of the coupling portion (CS) is relatively large.
도 2를 참조하면, 윤활유 카트리지(CT')는 목부(ST) 및 목부(ST)측에 위치하는 충진부(FP)의 적어도 일부가 윤활유 자동 공급 블록(EP)의 내부로 삽입되어 윤활유 자동 공급 블록(EP)에 결합될 수 있다. 이 때, 충진부(FP)의 나머지 일부만이 윤활유 자동 공급 블록(EP)의 외부에 위치하며 노출된다.Referring to FIG. 2, the lubricant cartridge (CT') automatically supplies lubricant by inserting the neck portion (ST) and at least a portion of the filling portion (FP) located on the neck portion (ST) into the interior of the lubricant automatic supply block (EP). It can be combined into a block (EP). At this time, only the remaining part of the filling part (FP) is exposed and located outside the lubricant automatic supply block (EP).
목부(ST) 및 충진부(FP)의 적어도 일부를 윤활유 자동 공급 블록(EP)에 삽입한 상태로 결합되는 구조에서, 윤활유 카트리지(CT')는 파편에 의한 충진부(FP)의 파손 문제를 방지할 수는 있으나, 윤활유(LB) 잔량 확인이 어렵다. 윤활유 카트리지(CT')는 윤활유 자동 공급 블록(EP)의 외부에 위치하는 충진부(FP)의 노출영역에 윤활유(LB)가 존재하는 상태에서는 광투과성 재질의 용기(CN)의 측면을 통해 외부에서 윤활유(LB) 소모량을 대략적으로 확인할 수 있다. 그런데, 충진부(FP)의 노출영역에 존재하는 윤활유(LB)가 점점 소모되어 윤활유 자동 공급 블록(EP) 내부에 위치하는 충진부(FP)의 비노출영역에만 윤활유(LB)가 잔존할 경우, 외부에서 윤활유(LB) 잔량을 확인하기가 어렵다. 따라서, 윤활유 자동 공급 블록(EP)로부터 윤활유 카트리지(CT')를 분리하지 않고는 윤활유 카트리지(CT')의 교체 시기를 정확하게 알 수 없다는 문제점이 있다.In a structure in which at least part of the neck (ST) and the filling part (FP) are inserted into the lubricant automatic supply block (EP), the lubricant cartridge (CT') prevents the problem of damage to the filling part (FP) by fragments. Although it can be prevented, it is difficult to check the remaining amount of lubricant (LB). The lubricant cartridge (CT') is supplied to the outside through the side of the container (CN) made of a light-transmissive material when lubricant (LB) is present in the exposed area of the filling part (FP) located outside the lubricant automatic supply block (EP). You can roughly check the lubricant (LB) consumption at . However, if the lubricant (LB) existing in the exposed area of the filling part (FP) is gradually consumed and the lubricant (LB) remains only in the non-exposed area of the filling part (FP) located inside the lubricant automatic supply block (EP), It is difficult to check the remaining amount of lubricant (LB) from the outside. Therefore, there is a problem that it is impossible to accurately know when to replace the lubricant cartridge (CT') without separating the lubricant cartridge (CT') from the lubricant automatic supply block (EP).
유압 브레이커의 작동중에는 윤활유 카트리지(CT')는 장착되어 있어야 하는데, 윤활유 카트리지(CT')의 안전한 보호 및 완벽한 결합을 위해서는 윤활유 카트리지(CT')는 윤활유 자동 공급 블록(EP)에 깊게 삽입되어야 한다. 하지만 이로 인해 윤활유 카트리지(CT') 내부에 남아 있는 윤활유(LB) 잔량을 확인하기 어려워 작업자가 윤활유 카트리지(CT')를 분리해서 잔량을 확인해야 하는 문제점이 있다.During the operation of the hydraulic breaker, the lubricant cartridge (CT') must be installed. For safe protection and perfect assembly of the lubricant cartridge (CT'), the lubricant cartridge (CT') must be deeply inserted into the lubricant automatic supply block (EP). . However, this causes a problem in that it is difficult to check the remaining amount of lubricant oil (LB) remaining inside the lubricant cartridge (CT'), requiring the operator to separate the lubricant cartridge (CT') to check the remaining amount.

도 3은 본 발명의 윤활유 카트리지(CT)가 장착되는 유압 브레이커(10)의 사시도이고, 도 4는 도 3의 A-A'를 따라 절단한 면을 도시한 도이다.Figure 3 is a perspective view of the hydraulic breaker 10 on which the lubricant cartridge (CT) of the present invention is mounted, and Figure 4 is a view showing a surface cut along line A-A' of Figure 3.
도 3 및 도 4를 참조하면, 유압 브레이커(10)는 실린더(12), 실린더(12) 내부에 구비되어 왕복 운동하는 피스톤, 피스톤의 왕복 운동을 제어하는 방향 제어 밸브 및 피스톤이 타격하는 치즐(16)을 구비하는 메인 바디(11)와, 메인 바디(11)를 감싸주면서 외부로부터 보호하는 브라켓(20)과, 메인 바디(11)에 윤활유 카트리지(CT)가 분리 가능하게 결합되는 윤활유 자동 공급 블록(EP)을 포함한다.Referring to Figures 3 and 4, the hydraulic breaker 10 includes a cylinder 12, a piston provided inside the cylinder 12 and reciprocating, a direction control valve controlling the reciprocating motion of the piston, and a chisel ( 16), a bracket 20 that surrounds the main body 11 and protects it from the outside, and a lubricant cartridge (CT) is detachably coupled to the main body 11 to automatically supply lubricant. Contains blocks (EP).
메인 바디(11)는 피스톤을 감싸는 실린더(12)와 실린더(12)의 하부에 위치하며 치즐(16)을 감싸는 프론트 헤드(15)와, 실린더(12)의 상부에 위치하는 백 헤드(17)가 장볼트에 의해 체결되어 상호 결합됨으로써 구성된다.The main body 11 includes a cylinder 12 surrounding the piston, a front head 15 located below the cylinder 12 and surrounding the chisel 16, and a back head 17 located above the cylinder 12. It is constructed by being fastened with long bolts and joined together.
메인 바디(11)는 백 헤드(17)의 일측면에 구비되는 작동유 유입부(18)를 통해 외부로부터 작동유를 공급받고, 타측면에 구비되는 작동유 배출부(19)를 통해 내부로 주입된 작동유를 외부로 배출한다.The main body 11 receives hydraulic oil from the outside through the hydraulic oil inlet 18 provided on one side of the bag head 17, and the hydraulic oil injected internally through the hydraulic oil outlet 19 provided on the other side. is discharged to the outside.
유압 브레이커(10)는 작동유 유입부(18)를 통해 유입된 작동유를 이용하여 피스톤을 반복적으로 상승 또는 하강시키고, 이를 통해 피스톤이 치즐(16)을 타격하면서 파쇄물을 파쇄시키는 타격력이 발생한다.The hydraulic breaker 10 repeatedly raises or lowers the piston using the hydraulic oil introduced through the hydraulic oil inlet 18, and through this, the piston strikes the chisel 16, generating a striking force that crushes the crushed material.
유압 브레이커(10)는 메인 바디(11)에 윤활유 카트리지(CT)가 분리 가능하게 결합되는 윤활유 자동 공급 블록(EP)을 구비한다.The hydraulic breaker 10 includes a lubricant automatic supply block (EP) in which a lubricant cartridge (CT) is detachably coupled to the main body 11.
윤활유 자동 공급 블록(EP)은 메인 바디(11)로부터 작동유를 공급받아 작동한다. 윤활유 자동 공급 블록(EP)은 작동유에 따라 작동하는 윤활유 피스톤을 구비한다. 윤활유 피스톤의 작동에 따라 윤활유 자동 공급 블록(EP)은 내부에 구비되는 윤활유 챔버로 윤활유 카트리지(CT)의 윤활유(LB)를 흡입하거나, 윤활유 챔버로 흡입된 윤활유(LB)를 메인 바디(11)로 공급하는 기능을 수행한다. 유압 브레이커(10)는 윤활유 자동 공급 블록(EP)을 통해 윤활유 카트리지(CT)의 윤활유(LB)를 공급받아 피스톤과 치즐(16)에 마찰에 따른 마모를 방지할 수 있다.The lubricant automatic supply block (EP) operates by receiving hydraulic oil from the main body (11). The lubricant automatic supply block (EP) has a lubricant piston that operates depending on the hydraulic oil. Depending on the operation of the lubricant piston, the lubricant automatic supply block (EP) sucks the lubricant (LB) of the lubricant cartridge (CT) into the lubricant oil chamber provided inside, or the lubricant (LB) sucked into the lubricant chamber into the main body (11). It performs the function of supplying. The hydraulic breaker 10 can prevent wear caused by friction on the piston and chisel 16 by receiving lubricant oil (LB) from the lubricant cartridge (CT) through the automatic lubricant supply block (EP).
한편, 윤활유 자동 공급 블록(EP)은 유압 브레이커(10)의 외부에 노출될 수 있다. 다시 말해, 윤활유 자동 공급 블록(EP)은 브라켓(20)의 외면에 외장형으로 구비도리 수 있다. 이 경우, 윤활유 자동 공급 블록(EP)은 작동유를 윤활유 자동 공급 블록(EP) 내부로 유입시키는 유압 라인과, 윤활유 자동 공급 블록(EP)에 결합된 윤활유 카트리지(CT)의 윤활유(LB)를 외부로 유출하는 유출 라인이 호스 형태로 구비되어 외장 형태로 설치될 수 있다.Meanwhile, the lubricant automatic supply block (EP) may be exposed to the outside of the hydraulic breaker 10. In other words, the lubricant automatic supply block (EP) may be provided externally on the outer surface of the bracket 20. In this case, the lubricant automatic supply block (EP) has a hydraulic line that introduces hydraulic oil into the lubricant automatic supply block (EP), and the lubricant oil (LB) of the lubricant cartridge (CT) coupled to the lubricant automatic supply block (EP) to the outside. The outflow line that flows out to the hose is provided in the form of a hose and can be installed in an external form.
이와는 달리, 윤활유 자동 공급 블록(EP)은 유압 브레이커(10)의 브라켓(20)의 내부에 내장 형태로 설치될 수도 있다. 다시 말해 윤활유 자동 공급 블록(EP)은 브라켓(20)의 내부에 위치하는 메인 바디(11)의 외면에 직결형으로 구비되거나 메인 바디(11)에 매립되는 내장형으로 구비될 수 있다. 이 경우, 윤활유 자동 공급 블록(EP)은 별도의 호스 없이 메인 바디(11) 내부에 형성된 작동유 내부 유로를 통해 작동유를 공급받아 작동한다. 윤활유 자동 공급 블록(EP)은 작동유에 의해 작동하여 윤활유 카트리지(CT)의 윤활유(LB)를 윤활유 챔버로 흡입하거나, 윤활유 챔버의 윤활유(LB)를 메인 바디(11)의 내부에 형성된 윤활유 내부 유로로 유출시킨다. 윤활유 카트리지(CT)는 윤활유 자동 공급 블록(EP)의 내부에 일단부를 위치시켜 분리 가능하게 결합되되 타단부는 유압 브레이커(10)의 외부에 위치하며 노출된다.Alternatively, the lubricant automatic supply block (EP) may be installed as a built-in type inside the bracket 20 of the hydraulic breaker 10. In other words, the lubricant automatic supply block (EP) may be provided directly on the outer surface of the main body 11 located inside the bracket 20, or may be provided as an embedded type embedded in the main body 11. In this case, the lubricating oil automatic supply block (EP) operates by receiving hydraulic oil through an internal hydraulic oil passage formed inside the main body 11 without a separate hose. The lubricant automatic supply block (EP) is operated by hydraulic oil to suck the lubricant (LB) from the lubricant cartridge (CT) into the lubricant chamber, or to suck the lubricant (LB) from the lubricant chamber into the lubricant internal passage formed inside the main body (11). It leaks out to The lubricant cartridge (CT) is detachably coupled with one end located inside the lubricant automatic supply block (EP), and the other end is located outside the hydraulic breaker 10 and is exposed.
이처럼 유압 브레이커(10)는 윤활유 카트리지(CT)를 분리 가능하게 결합하기 위한 윤활유 자동 공급 블록(EP)을 구비하되, 직결형의 윤활유 자동 공급 블록(EP), 외장형의 윤활유 자동 공급 블록(EP) 및 내장형의 윤활유 자동 공급 블록(EP) 중 적어도 하나로 윤활유 자동 공급 블록(EP)을 구비한다. 도 4에서는 일 예로서 직결 구조의 윤활유 자동 공급 블록(EP)이 구비된다.In this way, the hydraulic breaker 10 is provided with a lubricant automatic supply block (EP) for detachably combining the lubricant cartridge (CT), and includes a direct-type lubricant automatic supply block (EP) and an external lubricant automatic supply block (EP). and at least one of a built-in lubricant automatic supply block (EP). In Figure 4, as an example, a lubricant automatic supply block (EP) of a direct connection structure is provided.
윤활유 자동 공급 블록(EP)은 메인 바디(11)의 외면에 장착되어 직결되는 구조로 구비될 수 있다. 도 4를 참조하면, 윤활유 자동 공급 블록(EP)은 브라켓(20)의 내부에 위치하여 외부로 노출되지 않을 수 있다. 본 발명의 윤활유 카트리지(CT)는 윤활유 자동 공급 블록(EP)의 결합 부위(CS)에 주입구(ET)를 포함하는 일단부가 삽입되어 결합된다. 이 때, 윤활유 카트리지(CT)는 윤활유 자동 공급 블록(EP)의 내부에 위치하는 일단부를 제외한 나머지 부분이 브라켓(20)을 관통하여 외부로 노출되게 위치한다.The automatic lubricating oil supply block (EP) may be mounted on the outer surface of the main body 11 and may be provided in a directly connected structure. Referring to FIG. 4, the lubricant automatic supply block (EP) is located inside the bracket 20 and may not be exposed to the outside. The lubricant cartridge (CT) of the present invention is coupled by inserting one end including the injection port (ET) into the coupling portion (CS) of the lubricant automatic supply block (EP). At this time, the remaining portion of the lubricant cartridge (CT), except for one end located inside the automatic lubricant supply block (EP), is positioned so that it penetrates the bracket 20 and is exposed to the outside.
도 5는 본 발명의 윤활유 카트리지(CT)를 도시한 도이다.Figure 5 is a diagram showing the lubricant cartridge (CT) of the present invention.
도 5를 참조하면, 본 발명의 윤활유 카트리지(CT)는 윤활유(LB)가 충진되는 광투과성 재질의 용기(CN)와, 용기(CN)의 내부에서 윤활유(LB)의 잔량을 따라 슬라이드 이동하는 슬라이더(SL) 및 용기(CN)의 외주면에 구비되는 지시선(IL)을 포함한다.Referring to FIG. 5, the lubricant cartridge (CT) of the present invention includes a container (CN) made of a light-transparent material filled with lubricant oil (LB), and a container (CN) that slides along the remaining amount of lubricant (LB) inside the container (CN). It includes an indicator line (IL) provided on the outer peripheral surface of the slider (SL) and the container (CN).
용기(CN)는 광투과성 재질로 구성된다. 광투과성 재질을 투명 재질 또는 반투명 재질을 포함한다. 이에 따라 용기(CN)는 외부에서 용기(CN)를 통해 지시선(IL)을 확인하는 것이 가능하다.The container (CN) is made of a light-transmissive material. Light-transmissive materials include transparent or translucent materials. Accordingly, it is possible to check the indicator line (IL) of the container (CN) through the container (CN) from the outside.
용기(CN)는 윤활유(LB)가 충진되는 충진부(FP) 및 충진부(FP)와 연통되고 주입구(ET)를 포함하여 충진부(FP)의 윤활유(LB)를 배출시키는 통로 기능을 수행하는 목부(ST)로 구성된다. 용기(CN)는 충진부(FP)의 바닥부(GP)에 의해 일측이 폐쇄되고, 목부(ST)의 주입구(ET)를 통해 타측이 개방된다.The container (CN) is in communication with the filling part (FP) and the filling part (FP) where the lubricating oil (LB) is filled, and includes an injection port (ET) to perform a passage function to discharge the lubricating oil (LB) from the filling part (FP). It consists of the xylem (ST). One side of the container CN is closed by the bottom GP of the filling part FP, and the other side is open through the injection port ET of the neck ST.
충진부(FP)의 윤활유(LB)는 주입구(ET)를 통해 윤활유 자동 공급 블록(EP)의 윤할유 챔버로 공급된다.The lubricant oil (LB) of the filling part (FP) is supplied to the lubricant oil chamber of the automatic lubricant supply block (EP) through the injection port (ET).
윤활유 카트리지(CT)는 목부(ST)의 외면 및 목부(ST)측에 위치하는 충진부(FP)의 일단부의 외면에 나사산을 구비할 수 있다. 이 경우, 바람직하게는, 윤활유 자동 공급 블록(EP)의 결합 부위(CS)의 내부에는 윤활유 카트리지(CT)의 외면에 구비된 나사산과 결합 가능한 나사산이 구비될 수 있다. 윤활유 카트리지(CT)는 외면의 적어도 일부에 구비되는 나사산을 통해 윤활유 자동 공급 블록(EP)에 돌려서 결합하는 방식으로 분리 가능하게 결합될 수 있다.The lubricant cartridge (CT) may be provided with threads on the outer surface of the neck portion (ST) and on the outer surface of one end of the filling portion (FP) located on the neck portion (ST) side. In this case, preferably, the interior of the coupling portion (CS) of the lubricant automatic supply block (EP) may be provided with a screw thread that can be coupled to the screw thread provided on the outer surface of the lubricant cartridge (CT). The lubricant cartridge (CT) may be detachably coupled to the lubricant automatic supply block (EP) by turning it through threads provided on at least a portion of the outer surface.
용기(CN)는 충진부(FP)의 외면에 지시선(IL)을 구비한다. 지시선(IL)은 용기(CN)의 외면에 부착형 스티커 형태로 구비될 수 있고, 용기(CN)의 외면의 특정 위치에 인쇄되는 형태로 구비될 수도 있다. The container (CN) has an indicator line (IL) on the outer surface of the filling part (FP). The indicator line IL may be provided in the form of an attachable sticker on the outer surface of the container CN, or may be provided in the form of being printed at a specific location on the outer surface of the container CN.
지시선(IL)은 윤활유 카트리지(CT)의 교체 시기를 안내하는 표시선이거나 용기(CN)내에 잔존하는 윤활유(LB)의 용량을 표시하는 표시선일 수 있다.The indicator line IL may be an indicator line guiding the replacement time of the lubricant cartridge CT or an indicator line indicating the capacity of the lubricant oil LB remaining in the container CN.
지시선(IL)은, 충진부(FP)의 외면에 구비되되, 바람직하게는, 목부(ST)와 충진부(FP)를 연통시키는 연통 부위측과 상대적으로 가까운 위치에 구비된다. 보다 구체적으로, 충진부(FP)는 용기(CN)의 일측을 폐쇄하는 바닥부(GP)를 포함하고, 바닥부(GP)와 반대되는 방향에 위치하여 목부(ST)와 연결되는 리미트부(LT)를 포함한다. 지시선(IL)은 리미트부(LT)의 외면에 구비된다. 윤활유(LB)가 점차 소모되어 리미트부(LT)에만 잔존할 경우, 윤활유 카트리지(CT)의 교체가 필요한 시점이다. 지시선(IL)은 윤활유(LB)의 잔량을 확인하여 윤활유 카트리지(CT)의 교체 시기를 정확하게 알려주는 기능을 제공하므로, 바람직하게는, 리미트부(LT)의 외면에 구비된다.The indicator line IL is provided on the outer surface of the filling portion FP, and is preferably provided at a position relatively close to the communication portion that communicates the neck portion ST and the filling portion FP. More specifically, the filling part (FP) includes a bottom part (GP) that closes one side of the container (CN), and a limit part located in the opposite direction to the bottom part (GP) and connected to the neck part (ST) LT). The indicator line (IL) is provided on the outer surface of the limit portion (LT). When the lubricant (LB) is gradually consumed and remains only in the limit part (LT), it is time to replace the lubricant cartridge (CT). The indicator line (IL) checks the remaining amount of lubricant (LB) and provides a function of accurately informing the replacement time of the lubricant cartridge (CT), so it is preferably provided on the outer surface of the limit portion (LT).
다만, 지시선(IL)의 위치는 이에 한정되는 것은 아니고 본 발명에 따라 윤활유(LB)의 잔량의 정도를 확인할 수 있는 위치라면 모두 가능하다.However, the position of the indicator line IL is not limited to this and can be any position where the level of remaining lubricant oil LB can be confirmed according to the present invention.
본 발명의 윤활유 카트리지(CT)가 윤활유 자동 공급 블록(EP)에 결합된 상태에서, 리미트부(LT)의 외면에 구비된 지시선(IL)은 윤활유 자동 공급 블록(EP)의 결합 부위(CS)의 길이의 치수가 큰 경우 윤활유 자동 공급 블록(EP)의 내부에 위치할 수 있고, 윤활유 자동 공급 블록(EP)의 결합 부위(CS)의 길이의 치수가 작은 경우 윤활유 자동 공급 블록(EP)의 외부에 노출되게 위치할 수도 있다.When the lubricant cartridge (CT) of the present invention is coupled to the lubricant automatic supply block (EP), the indicator line (IL) provided on the outer surface of the limit portion (LT) is the coupling portion (CS) of the lubricant automatic supply block (EP) If the length of the lubricant automatic supply block (EP) is large, it can be located inside the lubricant automatic supply block (EP), and if the length of the coupling part (CS) of the lubricant automatic supply block (EP) is small, it can be located inside the lubricant automatic supply block (EP). It may be located exposed to the outside.
다시 말해, 유압 브레이커(10)는 크기 및 기종별로 윤활유 자동 공급 블록(EP)의 결합 부위(CS)의 길이의 치수가 다를 수 있다. 이에 따라, 지시선(IL)은 윤활유 자동 공급 블록(EP)의 결합 부위(CS)의 길이의 치수의 크기에 따라 윤활유 자동 공급 블록(EP)의 내부에 위치하거나, 윤활유 자동 공급 블록(EP)의 외부에 노출되게 위치할 수 있다.In other words, the hydraulic breaker 10 may have different length dimensions of the coupling portion (CS) of the lubricant automatic supply block (EP) depending on the size and model. Accordingly, the indicator line IL is located inside the lubricant automatic supply block (EP) or in the lubricant automatic supply block (EP) depending on the size of the length of the coupling portion (CS) of the lubricant automatic supply block (EP). It can be located exposed to the outside.
슬라이더(SL)는 충진부(FP)의 내부 직경보다 작은 직경을 갖는 판부(P) 및 판부(P)로부터 바닥부(GP)측으로 연장되는 플랜지부(FL)를 포함한다. 슬라이더(SL)의 형상은 이에 한정되지 않는다.The slider (SL) includes a plate portion (P) having a smaller diameter than the inner diameter of the filling portion (FP) and a flange portion (FL) extending from the plate portion (P) toward the bottom portion (GP). The shape of the slider SL is not limited to this.
슬라이더(SL)는 윤활유(LB) 잔량에 따라 바닥부(GP)측에 가깝게 위치하거나, 리미트부(LT)측에 가깝게 위치한다. 충진부(FP)에 충분한 양의 윤활유(LB)가 존재할 때, 슬라이더(SL)는 바닥부(GP)측에 상대적으로 가깝게 위치하고, 윤활유(LB)가 점점 소모되어 리미트부(LT)에만 잔존하거나 목부(ST)의 통로에만 잔존할 때, 슬라이더(SL)는 리미트부(LT)측에 상대적으로 가깝게 위치한다. 슬라이더(SL)는 윤활유 잔량에 따라 충진부(FP)의 바닥부(GP)측에서부터 리미트부(LT)측으로 슬라이드 이동한다.The slider (SL) is located close to the bottom part (GP) or close to the limit part (LT) side depending on the remaining amount of lubricant oil (LB). When a sufficient amount of lubricant oil (LB) exists in the filling part (FP), the slider (SL) is located relatively close to the bottom part (GP), and the lubricant oil (LB) is gradually consumed and remains only in the limit part (LT). When remaining only in the passage of the neck (ST), the slider (SL) is located relatively close to the limit portion (LT). The slider (SL) slides from the bottom (GP) side of the filling part (FP) to the limit part (LT) side according to the remaining amount of lubricant.
본 발명의 윤활유 카트리지(CT)는, 윤활유(LB)가 점점 소모되어 지시선(IL)의 위치와 리미트부(LT)의 벽면(WS) 사이의 거리(R)와 대응되는 영역 내에 윤활유(LB)가 잔존하게 되면, 용기(CN)의 바닥부(GP)를 통해 지시선(IL)이 투시된다.In the lubricating oil cartridge (CT) of the present invention, the lubricating oil (LB) is gradually consumed and the lubricating oil (LB) is stored in an area corresponding to the distance (R) between the position of the indicator line (IL) and the wall surface (WS) of the limit portion (LT). When remains, the indicator line IL is projected through the bottom GP of the container CN.

In this case, the indicator line IL is obscured by the lubricant LB and is not transparent through the bottom surface GS of the container CN. However, when the lubricant (LB) is gradually consumed and the lubricant (LB) remains in the area corresponding to the distance (R) between the walls (WS) of the limit part (LT), the indicator line ( IL) is transparent so that the indicator line (IL) can be identified through the bottom surface (GS) of the container (CN).
본 발명의 윤활유 카트리지(CT)는 윤활유(LB)의 잔량이 특정 용량 이하가 되면 지시선(IL)이 투시되도록 용기(CN)의 외면에 지시선(IL)을 구비한다. 이에 따라 윤활유 카트리지(CT)는 윤활유(LB)의 잔량이 특정 용량 이하가 되면 용기(CN)의 바닥면(GS)을 통해 지시선(IL)이 투시되어 보이게 된다. The lubricant cartridge (CT) of the present invention is provided with an indicator line (IL) on the outer surface of the container (CN) so that the indicator line (IL) is transparent when the remaining amount of lubricant oil (LB) falls below a certain capacity. Accordingly, when the remaining amount of lubricant oil (LB) in the lubricant oil cartridge (CT) falls below a certain capacity, the indicator line (IL) is visible through the bottom surface (GS) of the container (CN).
따라서, 본 발명의 윤활유 카트리지(CT)는 유압 브레이커(10)의 기종 및 크기와 관계없이 윤활유 자동 공급 블록(EP)에 결합된 상태에서 분리되지 않고도 지시선(IL)의 위치를 육안으로 확인하여 윤활유(LB) 잔량을 확인할 수 있다. 이를 통해 윤활유 카트리지(CT)는 교체 시기를 정확하게 알 수 있다.Therefore, the lubricant cartridge (CT) of the present invention, regardless of the type and size of the hydraulic breaker (10), visually checks the position of the indicator line (IL) without being separated from the lubricant automatic supply block (EP) and lubricates the lubricant. (LB) You can check the remaining amount. Through this, you can accurately know when to replace the lubricant cartridge (CT).

An indicator line (IL) is provided on the outer surface of the limit part (LT) of (CN). Accordingly, if the lubricant oil LB remains in the area of the filling part FP corresponding to the distance RQ, the indicator line IL is exposed.
제1실시 예의 윤활유 카트리지(CT1)는, 충진부(FP)의 윤활유(LB)가 소모되어 슬라이더(SL)가 용기(CN)의 주입구(ET)측으로 이동하여 슬라이더(SL)의 판부(P)가 지시선(IL)에 중첩하면 용기(CN)의 내부(보다 구체적으로, 용기(CN)의 바닥면(GS))를 육안으로 들여다봄으로써 지시선(IL)의 위치를 육안으로 확인 가능하다.In the lubricating oil cartridge (CT1) of the first embodiment, the lubricating oil (LB) in the filling part (FP) is consumed and the slider (SL) moves to the inlet (ET) side of the container (CN) and the plate part (P) of the slider (SL) If it overlaps the indicator line IL, the position of the indicator line IL can be visually confirmed by visually looking into the inside of the container CN (more specifically, the bottom surface GS of the container CN).
구체적으로, 제1실시 예의 윤활유 카트리지(CT1)는 윤활유 자동 공급 블록(EP)에 결합된 상태에서 지시선(IL)이 윤활유 자동 공급 블록(EP)의 내부에 위치하여 외부에 노출되지 않는다. 일 예로서, 윤활유 자동 공급 블록(EP)은 결합 부위(CS)의 길이가 상대적으로 크게 구비될 수 있다. 이 때, 제1실시 예의 윤활유 카트리지(CT1)는 광투과성 재질의 슬라이더(SL)를 구비함에 따라 슬라이더(SL)가 주입구(ET)측으로 이동하여 전체적으로 지시선(IL)을 벗어나지 않더라도, 슬라이더(SL)의 판부(P)가 지시선(IL)에 중첩되게 위치하는 시점에서 용기(CN)의 바닥면(GS)을 통해 지시선(IL)의 위치를 확인하는 것이 가능하다. 따라서, 제1실시 예의 윤활유 카트리지(CT1)는 윤활유(LB)의 잔량이 거리(RQ)에 대응하는 영역 내에 남아있을 때 용기(CN)의 바닥면(GS)을 통해 지시선(IL)의 위치가 확인되도록 하기 위해 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 거리(RQ)만큼 이격된 지점에 대응하는 용기(CN)의 외면에 지시선(IL)을 구비한다. 지시선(IL)은 주입구(ET)측에 상대적으로 가깝게 위치하여 윤활유 카트리지(CT1)가 윤활유 자동 공급 블록(EP)에 결합된 상태에서 윤활유 자동 공급 블록(EP)의 내부에 위치하며 노출되지 않을 수 있다.Specifically, while the lubricant cartridge CT1 of the first embodiment is coupled to the lubricant automatic supply block EP, the indicator line IL is located inside the lubricant automatic supply block EP and is not exposed to the outside. As an example, the automatic lubricating oil supply block (EP) may have a relatively long coupling portion (CS). At this time, the lubricant cartridge (CT1) of the first embodiment is provided with a slider (SL) made of a light-transmissive material, so even if the slider (SL) moves toward the injection port (ET) and does not deviate from the indicator line (IL) as a whole, the slider (SL) It is possible to check the position of the indicator line (IL) through the bottom surface (GS) of the container (CN) at the point where the plate portion (P) of is positioned to overlap the indicator line (IL). Accordingly, the lubricant cartridge CT1 of the first embodiment has the position of the indicator line IL through the bottom surface GS of the container CN when the remaining amount of lubricant oil LB remains in the area corresponding to the distance RQ.

슬라이더(SL)가 제3지시선(IL3)을 벗어나 주입구(ET)측으로 더 슬라이드 이동하여 슬라이더(SL)의 판부(P)가 제2지시선(IL2)에 중첩되면, 용기(CN)의 바닥면(GS)을 통해 제2지시선(IL2)의 위치가 확인된다. 이를 통해 윤활유(LB)의 잔량이 제2지시선(IL2)의 위치만큼의 부피로 있음을 확인 가능하다.When the slider (SL) moves beyond the third indicator line (IL3) and slides further toward the inlet (ET) and the plate part (P) of the slider (SL) overlaps the second indicator line (IL2), the bottom surface of the container (CN) The position of the second indicator line (IL2) is confirmed through GS). Through this, it can be confirmed that the remaining amount of lubricant oil (LB) is in a volume equal to the position of the second indicator line (IL2).
그런 다음, 윤활유(LB)가 더욱 소모됨에 따라 슬라이더(SL)가 제2지시선(IL2)을 벗어나 주입구(ET)측으로 더 슬라이드 이동하여 슬라이더(SL)의 판부(P)가 제1지시선(IL1)에 중첩되면, 용기(CN)의 바닥면(GS)을 통해 제1지시선(IL1)의 위치가 확인된다. 이를 통해 윤활유(LB)의 잔량이 제1지시선(IL1)의 위치만큼의 부피로 있음을 확인 가능하다.Then, as the lubricant oil (LB) is further consumed, the slider (SL) moves beyond the second indicator line (IL2) and slides further toward the injection port (ET), so that the plate portion (P) of the slider (SL) moves toward the first indicator line (IL1). When overlapped, the position of the first indicator line IL1 is confirmed through the bottom surface GS of the container CN. Through this, it can be confirmed that the remaining amount of lubricating oil LB is in a volume equal to the position of the first indicator line IL1.
제1실시 예의 윤활유 카트리지(CT1)의 변형 예는 제1 내지 3지시선(IL1, IL2, IL3)을 주입구(ET)측에서 바닥부(GP)가 위치하는 방향으로 순차적으로 구비하여 윤활유(LB)가 소모됨에 따라 제3지시선(IL3), 제2지시선(IL2) 및 제1지시선(IL1)을 통해 윤활유(LB)의 잔량이 순차적으로 확인된다. 이로 인해 윤활유 카트리지(CT1)를 윤활유 자동 공급 블록(EP)로부터 분리되지 않고도 윤활유(LB)의 잔량이 순차적으로 확인되고, 용기(CN)를 통해 제1지시선(IL1)의 위치가 확인되는 시점에 정확하게 교체될 수 있다.A modified example of the lubricant cartridge (CT1) of the first embodiment is provided with first to third indicator lines (IL1, IL2, IL3) sequentially from the injection port (ET) side to the direction where the bottom (GP) is located, so that the lubricant (LB) As is consumed, the remaining amount of lubricant oil (LB) is sequentially checked through the third indicator line (IL3), the second indicator line (IL2), and the first indicator line (IL1).

도 8은 제2실시 예의 윤활유 카트리지(CT2)가 윤활유 자동 공급 블록(EP)에 결합된 상태를 개략적으로 도시한 도이다.Figure 8 is a diagram schematically showing a state in which the lubricant cartridge (CT2) of the second embodiment is coupled to the lubricant automatic supply block (EP).
도 8을 참조하면, 제2실시 예의 윤활유 카트리지(CT2)는, 광 불투과성 재질의 슬라이더(SL)를 구비한다는 점에서 제1실시 예의 윤활유 카트리지(CT2)와 차이가 있다. 이하에서는 제1실시 예의 윤활유 카트리지(CT2)와 비교하여 특징적인 구성요소들을 중심으로 설명하겠으며, 동일하거나 유사한 구성요소들에 대한 설명은 되도록이면 생략한다.Referring to FIG. 8, the lubricant cartridge CT2 of the second embodiment differs from the lubricant cartridge CT2 of the first embodiment in that it is provided with a slider SL made of a light-opaque material. Hereinafter, the description will focus on the characteristic components compared to the lubricant cartridge CT2 of the first embodiment, and descriptions of the same or similar components will be omitted if possible.
따라서, 제2실시 예의 윤활유 카트리지(CT2)는 슬라이더(SL)의 판부(P)가 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 거리(RQ)만큼 이격된 지점에 위치한 상태에서 바닥부(GP)가 위치하는 방향으로 슬라이더(SL)의 플랜지부(FL)와 인접하는 일측의 특정 지점과 대응되는 용기(CN)의 외면에 지시선(IL)을 구비한다. 지시선(IL)은 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 제1거리(R1)만큼 이격된 위치에 구비된다.Accordingly, in the lubricant cartridge CT2 of the second embodiment, the plate portion P of the slider SL is spaced apart by a distance RQ from the wall surface WS of the limit portion LT in the direction in which the bottom portion GP is located. When located at the point, an indicator line IL is provided on the outer surface of the container CN corresponding to a specific point on one side adjacent to the flange portion FL of the slider SL in the direction in which the bottom portion GP is located. The indicator line IL is provided at a position spaced apart from the wall surface WS of the limit portion LT by a first distance R1 in the direction in which the floor portion GP is located.
제2실시 예의 윤활유 카트리지(CT2)는 윤활유 자동 공급 블록(EP)에 결합된 상태에서 지시선(IL)이 윤활유 자동 공급 블록(EP)의 외부에 위치하여 노출된다. 일 예로서, 제2실시 예의 윤활유 카트리지(CT2)는 결합 부위(CS)의 길이의 치수가 상대적으로 작은 윤활유 자동 공급 블록(EP)에 결합될 수 있다. 제2실시 예의 윤활유 카트리지(CT2)는 광 불투과성 재질의 슬라이더(SL)를 구비한다. 따라서, 슬라이더(SL)가 주입구(ET)측으로 이동하여 슬라이더(SL)의 판부(P)가 지시선(IL)을 먼저 벗어나고 플랜지부(FL)까지 지시선(IL)을 벗어나게 위치하면 용기(CN)를 투과하여 지시선(IL)의 위치를 확인하는 것이 가능하다. The lubricant cartridge (CT2) of the second embodiment is coupled to the lubricant automatic supply block (EP), and the indicator line (IL) is exposed and positioned outside the lubricant automatic supply block (EP). As an example, the lubricant cartridge CT2 of the second embodiment may be coupled to the automatic lubricant supply block EP where the length of the coupling portion CS is relatively small. The lubricant cartridge (CT2) of the second embodiment includes a slider (SL) made of a light-opaque material. Therefore, when the slider (SL) moves toward the injection port (ET) and the plate part (P) of the slider (SL) deviates from the indicator line (IL) first, and the flange part FL is positioned beyond the indicator line (IL), the container CN is It is possible to check the position of the indicator line (IL) through penetration.
도 8을 참조하면, 점선으로 표시된 슬라이더(SL)의 위치는, 윤활유(LB)의 잔량에 따라 슬라이더(SL)가 바닥부(GP)측에서부터 주입구(ET)측으로 이동한 위치이다.Referring to FIG. 8, the position of the slider SL indicated by a dotted line is the position where the slider SL moves from the bottom GP side to the injection port ET side according to the remaining amount of lubricant oil LB.
슬라이더(SL)의 위치가 실선으로 표시된 슬라이더(SL)의 위치일 경우, 윤활유(LB)가 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 거리(RQ)만큼 이격된 지점에 대응하는 영역을 벗어나 그 이상의 영역에도 존재하는 상태이다. 이 경우에는 용기(CN)의 측면을 통해 윤활유(LB)의 잔량을 가늠해 볼 수는 있다. 또한, 작업자는 용기(CN)의 바닥부(GP)를 통해 지시선(IL)의 위치가 확인되지 않으므로, 윤활유(LB)의 잔량이 충분한 상태임을 확인할 수 있다.When the position of the slider (SL) is indicated by a solid line, the lubricant (LB) flows from the wall surface (WS) of the limit part (LT) to the distance (RQ) in the direction where the bottom part (GP) is located. It is a state that goes beyond the area corresponding to the separated point and exists in a further area. In this case, the remaining amount of lubricant oil (LB) can be measured through the side of the container (CN). Additionally, since the position of the indicator line IL is not confirmed through the bottom GP of the container CN, the operator can confirm that the remaining amount of lubricant oil LB is sufficient.
슬라이더(SL)가 점선으로 표시된 슬라이더(SL)의 위치에 위치하면, 윤활유(LB)는 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 거리(RQ)만큼 이격된 지점에 대응하는 영역 내에 존재하는 상태이다. 이 때, 슬라이더(SL)는, 주입구(ET)가 위치하는 방향을 기준으로 판부(P) 및 플랜지부(FL) 모두가 지시선(IL)의 일측으로 벗어나게 위치한 상태이다. 슬라이더(SL)가 전체적으로 지시선(IL)을 벗어나게 위치하면, 용기(CN)의 바닥부(GP)를 투과해서 지시선(IL)이 확인된다. 이를 통해 윤활유(LB)의 잔량을 확인하고 교체 시기에 정확하게 윤활유 카트리지(CT2)를 교체할 수 있다. 다만, 이 경우에는 용기(CN)의 측면을 통해 윤활유(LB)의 잔량에 따른 용기(CN) 측면의 색상 변화로 윤활유(LB)의 잔량을 확인할 수도 있다. 그러나, 결합 부위(CS)의 길이가 길어 결합 부위(CS)가 지시선(IL)을 덮는 경우에는 용기(CN)의 측면을 통한 잔량 확인은 어렵고 용기(CN)의 바닥면(GS)을 통해 잔량 확인이 이루어진다.When the slider (SL) is located at the position indicated by the dotted line, the lubricant (LB) is spaced apart by the distance (RQ) from the wall surface (WS) of the limit part (LT) in the direction where the bottom part (GP) is located. It is a state that exists within the area corresponding to the specified point. At this time, the slider SL is in a state in which both the plate portion P and the flange portion FL are located to one side of the indicator line IL based on the direction in which the injection port ET is located. If the slider SL is positioned entirely outside the indicator line IL, the indicator line IL is confirmed through the bottom GP of the container CN. Through this, you can check the remaining amount of lubricant (LB) and replace the lubricant cartridge (CT2) accurately at the replacement time. However, in this case, the remaining amount of lubricant oil (LB) can be confirmed through a color change on the side of the container (CN) according to the remaining amount of lubricant oil (LB) through the side of the container (CN). However, if the binding site (CS) is long and covers the indicator line (IL), it is difficult to check the remaining amount through the side of the container (CN) and check the remaining amount through the bottom surface (GS) of the container (CN). Confirmation is made.
도 9는 제2실시 예의 윤활유 카트리지(CT2)의 제1변형 예가 윤활유 자동 공급 블록(EP)에 결합된 상태를 개략적으로 도시한 도이다. 제2실시 예의 제1변형 예는, 지시선(IL)을 복수개 구비한다. 이하에서는 지시선(IL)의 개수를 2개인 것으로 하여 설명하고 있으나 지시선(IL)의 개수는 이에 한정되는 것은 아니다.Figure 9 is a diagram schematically showing a state in which the first modified example of the lubricant cartridge CT2 of the second embodiment is coupled to the lubricant automatic supply block EP. The first modification of the second embodiment includes a plurality of indicator lines IL. Below, the number of indicator lines (IL) is described as two, but the number of indicator lines (IL) is not limited to this.

It is provided at a point spaced apart from the wall surface WS of the unit LT by a second distance R2 in the direction in which the floor unit GP is located. The length of the first distance (R1) is smaller than the length of the second distance (R2), and the length of the second distance (R2) is larger than the length of the first distance (R1). Accordingly, the first indicator line IL1 is located relatively close to the injection port ET, and the second indicator line IL2 is located relatively far from the injection port ET.
제2실시 예의 제1변형 예는, 복수개의 지시선(IL1, IL2)를 구비함으로써 복수개의 지시선(IL1, IL2) 중 슬라이더(SL)의 이동에 따라 노출되는 지시선의 위치를 확인하여 윤활유(LB)의 잔량을 순차적으로 확인할 수 있다.The first modified example of the second embodiment is provided with a plurality of indicator lines (IL1, IL2), so that the position of the indicator line exposed according to the movement of the slider (SL) among the plurality of indicator lines (IL1, IL2) is confirmed and the lubricant (LB) You can check the remaining amount sequentially.
구체적으로, 주입구(ET)가 위치하는 방향을 기준으로 슬라이더(SL)가 제2지시선(IL2)의 일측으로 벗어나게 위치한 상태에서 제2지시선(IL2)은 투시된다. 제1지시선(IL1)은 슬라이더(SL)의 적어도 일부 또는 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 제2거리(R2)만큼 이격된 지점까지와 대응되는 영역 내에 존재하는 윤활유(LB)에 의해 가려진 상태로 투시되지 않는다.Specifically, the second indicator line IL2 is transparent when the slider SL is positioned off to one side of the second indicator line IL2 based on the direction in which the injection port ET is located. The first indicator line IL1 corresponds to a point spaced apart by a second distance R2 in the direction in which the floor part GP is located from at least a portion of the slider SL or the wall surface WS of the limit part LT. It is not transparent as it is obscured by the lubricant (LB) present in the area.
제2실시 예의 제1변형 예는, 슬라이더(SL)의 이동에 따라 제2지시선(IL2)이 투시되어 제2지시선(IL2)의 위치가 확인되고, 제2지시선(IL2)만이 투시됨에 따라 윤활유(LB)의 잔량이 충분함을 확인하여 교체 시기가 아님을 정확하게 확인할 수 있다.In the first modified example of the second embodiment, the second indicator line IL2 is transparent as the slider SL moves, so that the position of the second indicator line IL2 is confirmed, and only the second indicator line IL2 is transparent, so that the lubricant By checking that the remaining amount of (LB) is sufficient, you can accurately confirm that it is not time for replacement.
제2실시 예의 제1변형 예는, 윤활유(LB)가 소모됨에 따라 슬라이더(SL)가 주입구(ET)측으로 더 이동하여 제1지시선(IL1)을 벗어나서 제1지시선(IL1)이 투시될 수 있다. 이를 통해 윤활유 카트리지(CT2)는 윤활유 자동 공급 블록(EP)로부터 분리하지 않고도 윤활유(LB)의 잔량이 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 거리(RQ)만큼 이격된 지점에 대응하는 영역 내에 존재하는 것을 확인하여 정확한 교체 시기에 교체될 수 있다.In the first modified example of the second embodiment, as the lubricating oil LB is consumed, the slider SL moves further toward the injection port ET, so that it deviates from the first indicator line IL1 and the first indicator line IL1 can be seen. . Through this, the lubricant cartridge (CT2) allows the remaining lubricant (LB) to be stored at a distance (RQ) from the wall surface (WS) of the limit part (LT) in the direction where the bottom part (GP) is located, without being separated from the lubricant automatic supply block (EP). ) can be replaced at the correct replacement time by confirming that it exists in the area corresponding to the point spaced apart.

도 11은 제2실시 예의 윤활유 카트리지(CT2)의 제3변형 예를 윤활유 자동 공급 블록(EP)에 결합한 상태를 개략적으로 도시한 도이다. Figure 11 is a diagram schematically showing a state in which a third modification of the lubricant cartridge CT2 of the second embodiment is coupled to the lubricant automatic supply block EP.
제2실시 예의 제3변형 예는 지시선(IL)을 복수개 구비하여 결합 부위(CS)의 길이의 치수가 상대적으로 큰 윤활유 자동 공급 블록(EP)에 결합된다. 일 예로서 제2실시 예의 제3변형 예는 제1지시선(IL1) 및 제2지시선(IL2)을 구비한다. 다만 지시선(IL)의 개수는 이에 한정되지 않는다.The third modification of the second embodiment is coupled to the lubricant automatic supply block EP, which has a plurality of indicator lines IL and has a relatively large length of the engaging portion CS. As an example, the third modification of the second embodiment includes a first indicator line (IL1) and a second indicator line (IL2). However, the number of indicator lines (IL) is not limited to this.
복수개의 지시선(IL1, IL2) 중 적어도 하나는 윤활유 자동 공급 블록(EP)의 내부에 위치할 수 있다. 일 예로서, 제1지시선(IL1)은 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 제1거리(R1)만큼 이격된 지점에 구비되어 윤활유 자동 공급 블록(EP)의 내부에 위치한다. 제2지시선(IL2)은 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 제2거리(R2)만큼 이격된 지점에 구비되어 윤활유 자동 공급 블록(EP)의 외부에 위치한다.At least one of the plurality of indicator lines (IL1, IL2) may be located inside the lubricant automatic supply block (EP). As an example, the first indicator line (IL1) is provided at a point spaced apart from the wall surface (WS) of the limit portion (LT) by a first distance (R1) in the direction in which the bottom portion (GP) is located, and is provided in the lubricant automatic supply block ( EP) is located inside. The second indicator line (IL2) is provided at a point spaced apart by a second distance (R2) from the wall surface (WS) of the limit part (LT) in the direction where the floor part (GP) is located, and is located outside the lubricant automatic supply block (EP). It is located in
슬라이더(SL)는 주입구(ET)측으로 이동하여 제2지시선(IL2)을 완전히 벗어나서 제1지시선(IL1)에 인접하게 위치하거나 판부(P)가 제1지시선(IL1)에 중첩되어 위치할 수 있다. 이에 따라 제2지시선(IL2)이 투시된다. The slider (SL) moves toward the injection port (ET) and completely deviates from the second indicator line (IL2) and is positioned adjacent to the first indicator line (IL1), or the plate portion (P) may be positioned overlapping the first indicator line (IL1). . Accordingly, the second indicator line (IL2) is transparent.
슬라이더(SL)는 제2지시선(IL2)을 벗어나게 위치한 상태에서 윤활유(LB)가 소모됨에 따라 주입구(ET)측으로 더 이동하여 제1지시선(IL1)을 벗어나게 위치할 수 있다. 이에 따라 윤활유 자동 공급 블록(EP)의 내부에서 윤활유(LB)에 의해 가려진 상태였던 제1지시선(IL1)이 투시된다.As the lubricant oil LB is consumed while being positioned beyond the second indicator line IL2, the slider SL may move further toward the injection port ET and be positioned beyond the first indicator line IL1. Accordingly, the first indicator line (IL1), which was obscured by the lubricant (LB) inside the automatic lubricant supply block (EP), is visible.
제2실시 예의 제3변형 예는 용기(CN)의 바닥면(GS)을 통해 윤활유 자동 공급 블록(EP)의 내부에 위치하는 제1지시선(IL1)의 위치가 확인됨에 따라 슬라이더(SL)의 잔량이 리미트부(LT)의 벽면(WS)으로부터 바닥부(GP)가 위치하는 방향으로 거리(RQ)에 대응하는 영역 내에 존재하는 것이 확인되도록 할 수 있다. 이로 인해 제2실시 예의 제3변형 예는 윤활유 카트리지(CT2)를 윤활유 자동 공급 블록(EP)로부터 분리하는 작업없이 용기(CN)를 통해 윤활유(LB)의 잔량을 육안으로 즉시 확인하여 교체 시기에 정확하게 교체될 수 있다.In the third modification of the second embodiment, the position of the first indicator line IL1 located inside the lubricant automatic supply block EP is confirmed through the bottom surface GS of the container CN, and the position of the slider SL is confirmed. It can be confirmed that the remaining amount exists within an area corresponding to the distance RQ in the direction in which the floor part GP is located from the wall surface WS of the limit part LT. For this reason, in the third modification of the second embodiment, the remaining amount of lubricant oil (LB) is immediately visually confirmed through the container (CN) without the operation of separating the lubricant cartridge (CT2) from the lubricant automatic supply block (EP), so that it can be replaced at the time of replacement.
