유압 브레이커용 유압호스 연결장치{Hydraulic hose connector for hydraulic breaker}Hydraulic hose connector for hydraulic breaker {Hydraulic hose connector for hydraulic breaker}

본 발명은 유압 브레이커용 유압호스 연결장치에 관한 것으로, 더욱 상세하게는 굴삭기와 같은 건설기계의 붐에 장착되는 파쇄용 유압 브레이커의 유압호스 연결부위에 장착되며 회전이 자유롭도록 하여 유압호스 및 그 체결기구인 어댑터의 파손을 방지할 수 있도록 한 유압 브레이커용 유압호스 연결장치에 관한 것이다.The present invention relates to a hydraulic hose connection device for a hydraulic breaker, and more particularly, to a hydraulic hose connection part of a crushing hydraulic breaker mounted on a boom of a construction machine such as an excavator, and the hydraulic hose and its fastening by allowing rotation to be free. It relates to a hydraulic hose connection device for a hydraulic breaker to prevent damage to the adapter, which is a mechanism.

일반적으로 굴삭기(Excavator)는 조종실과, 유압공급수단을 포함하는 엔진실, 실질적인 굴삭작업을 수행하기 위하여 상하좌우로 움직이는 붐대와, 작업용도에 따라 붐대의 끝에 분리 가능하게 장착되는 버켓 또는 유압 브레이커 등을 포함하여 구성된다.In general, an excavator is a cockpit, an engine room including a hydraulic supply means, a boom that moves up, down, left and right to perform actual excavation, and a bucket or hydraulic breaker detachably mounted at the end of the boom depending on the purpose of work. Consists of including.

이러한 굴삭기는 택지조성 작업, 건물 기초 작업, 각종 적재작업, 구멍파기, 교량 및 암반 등의 파쇄작업, 도로 및 상하수도 공사 등 다양한 작업을 수행할 수 있다.Such an excavator can perform a variety of tasks, such as land construction work, building foundation work, various loading work, digging holes, crushing work such as bridges and rock, road and water supply and sewage work.

즉, 모래나 흙 등을 적재하는 작업 등에는 붐대에 버켓을 장착하여 사용하고, 암반 파쇄나 터널 및 트랙 작업 등에는 붐대에 유압 브레이커를 장착하여 사용하게 된다.That is, a bucket is mounted on the boom for loading sand or soil, and a hydraulic breaker is mounted on the boom for rock crushing or tunnel and track work.

도 5에 나타낸 바와 같이, 종래 유압 브레이커는, 굴삭기의 붐대와 결합되는 결합체(100)와, 내부에 유압회로 및 유압작동수단 등이 내설되어 있는 메인바디(200)와, 이 메인바디(200)의 저면에 승하강 진동 가능하게 장착된 치즐(300)로 구성된다.As shown in FIG. 5, a conventional hydraulic breaker includes an assembly 100 coupled with a boom of an excavator, a main body 200 in which a hydraulic circuit and a hydraulic operating means, etc. are internally installed, and the main body 200 Consisting of a chisel 300 mounted to the bottom surface of the elevating vibration.

메인바디(200)의 양측면에는 굴삭기의 유압공급수단으로부터 연장된 유압호스가 체결되는 한 쌍의 유압호스 연결체(400)가 나란히 형성되어 있다.On both sides of the main body 200, a pair of hydraulic hose connectors 400 to which hydraulic hoses extending from the hydraulic supply means of the excavator are fastened are formed side by side.

따라서, 상기 유압호스 연결체(400)에 굴삭기의 유압공급수단으로부터 연장되어 온 유압호스(10)의 일측단이 체결용 어댑터(12)를 이용하여 고정된 상태로 체결됨에 따라, 굴삭기의 유압공급수단으로부터 제공된 유압이 상기 유압호스(10)를 경유하는 동시에 유압호스 연결체(400)를 통해 상기 유압 브레이커의 메인바디(200) 내로 제공된다.Therefore, as one end of the hydraulic hose 10 extending from the hydraulic supply means of the excavator is fastened to the hydraulic hose connector 400 in a fixed state using the fastening adapter 12, the hydraulic pressure of the excavator is supplied. The hydraulic pressure provided from the means passes through the hydraulic hose 10 and at the same time is provided into the main body 200 of the hydraulic breaker through the hydraulic hose connection body 400.

그에 따라, 유압 브레이커의 메인바디(200) 저면에 장착된 치즐(300)이 승하강 진동하며, 암반 또는 암석 등을 파쇄하는 작동을 하게 되는 것이다.Accordingly, the chisel 300 mounted on the bottom of the main body 200 of the hydraulic breaker vibrates up and down, and the operation of crushing rock or rock is performed.

그러나, 유압 브레이커의 유압호스 연결체에 유압호스를 체결하는 어댑터가 고정된 상태로 장착된 구조로 인해 유압호스(10) 및 어댑터(12)에 외력 또는 진동이 가해지게 되면, 피로가 가중되면서 결국에는 유압호스의 체결부위 및 어댑터가 파손되는 현상이 발생한다.However, when an external force or vibration is applied to the hydraulic hose 10 and the adapter 12 due to the structure in which the adapter for fastening the hydraulic hose to the hydraulic hose connector of the hydraulic breaker is mounted in a fixed state, fatigue is increased and eventually There occurs a phenomenon in which the hydraulic hose fastening part and adapter are damaged.

도 1 내지 도 4에 나타낸 바와 같이, 본 발명에 따른 유압 브레이커용 유압호스 연결장치(A)는, 연결부재(100), 제1회전부재(200), 연결몸체(300), 제2회전부재(400), 호스연결구(500)를 포함하여 구성된다. 1 to 4, the hydraulic hose connection device (A) for a hydraulic breaker according to the present invention, a connecting member 100, a first rotating member 200, a connecting body 300, a second rotating member (400), it is configured to include a hose connector 500.

연결부재(100)는, 유압브레이커(1)의 몸체(10)에 결합되는 결합부(110)가 일단에 형성되고, 내부에는 통로(112)가 형성되며, 통로(112)의 끝부분에 개구공(114)이 형성되고, 외주면에 복수의 유수홀(120)이 형성되며, 상기 복수의 유수홀(120)은 내부의 통로(112)와 통하도록 하여 구성된다.The connecting member 100 has a coupling part 110 coupled to the body 10 of the hydraulic breaker 1 formed at one end, a passage 112 formed therein, and an opening at the end of the passage 112 A hole 114 is formed, a plurality of flowing holes 120 are formed on the outer circumferential surface, and the plurality of flowing holes 120 is configured to communicate with the passage 112 inside.

제1회전부재(200)는, 상기 연결부재(100)의 외주면에 결합되며, 양단에 개구공이 형성된 통로(220)와, 통로(220)에 직각방향으로 통하도록 형성된 개구홀(221)이 상기 연결부재(100)의 유수홀(120)과 통하도록 결합되며, 상기 개구홀(221)과 통하는 체결부(230)가 형성된다.The first rotating member 200 is coupled to the outer circumferential surface of the connecting member 100 and has a passage 220 having opening holes formed at both ends, and an opening hole 221 formed to communicate with the passage 220 in a perpendicular direction. It is coupled to communicate with the flowing hole 120 of the connection member 100, and a fastening part 230 communicating with the opening hole 221 is formed.

바람직하게는 제1회전부재(200)는 유압브레이커(1)의 몸체(10)에 대해 평행되게 회전될 수 있도록 한다. Preferably, the first rotating member 200 is to be rotated in parallel with respect to the body 10 of the hydraulic breaker (1).

상기 연결부재(100)의 복수의 유수홀(120)은, 2개의 제1유수홀(120)이 서로 마주보게 형성되고, 2개의 제2유수홀(120')은 상기 제1유수홀(120)과 어긋나는 위치에 형성된다.The plurality of flowing holes 120 of the connecting member 100 are formed so that the two first flowing holes 120 face each other, and the two second flowing holes 120 ′ are the first flowing holes 120 ) Is formed in a position that deviates from it.

따라서 1쌍의 제1유수홀(120)과 또 다른 1쌍의 제2유수홀(120') 간에 위치가 상이하되 각기 90도 간격으로 배열되며, 이렇게 어긋나게 배열됨으로서 1쌍의 유수홀(120) 간의 간격과 나머지 1쌍의 유수홀(120) 간의 간격이 넓게 형성될 수 있어 파손의 위험성이 방지될 수 있다. Therefore, a pair of first flowing holes 120 and another pair of second flowing holes 120' have different positions, but are each arranged at 90 degree intervals, and as such, the pair of flowing holes 120 Since the gap between the gaps and the gap between the remaining pair of flowing holes 120 may be formed wide, the risk of damage may be prevented.

즉, 인접된 유수홀(120,120') 들 간의 간격을 적정하게 이격시킬 수 있어 내구성이 강화될 수 있는 것이다. That is, the distance between the adjacent flowing holes 120 and 120' can be properly spaced, thereby enhancing durability.

만약 인접된 유수홀(120,120') 들 간의 간격이 너무 근접할 경우 천공 과정에서 각 유수홀(120,120') 사이의 이격부위가 찢어지면서 파손될 우려가 있기 때문이다. This is because if the distance between the adjacent flowing holes 120 and 120 ′ is too close, there is a risk that the spaced portion between each flowing hole 120 and 120 ′ is torn and damaged during the drilling process.

상기 연결부재(100)의 외주면에는 밀폐를 위한 오링(150)이 장착되고, 상기 오링(150)이 제1회전부재(200)의 통로(220)의 내주면에 밀착되도록 한다. An O-ring 150 for sealing is mounted on the outer circumferential surface of the connecting member 100, and the O-ring 150 is in close contact with the inner circumferential surface of the passage 220 of the first rotating member 200.

연결몸체(300)는, 상기 제1회전부재(200)의 체결부(230)에 일단부가 결합되며, 내부에 이송로(320)가 형성되고, 외주면에는 이송로(320)에 통하도록 복수의 유입홀(340)이 형성되며, 이송로(320)와 통하도록 유출공(322)이 단부에 형성된다. The connection body 300 has one end coupled to the fastening part 230 of the first rotating member 200, and a transfer path 320 is formed therein, and a plurality of transfer paths 320 are formed on the outer circumferential surface thereof. An inlet hole 340 is formed, and an outlet hole 322 is formed at an end to communicate with the transfer path 320.

상기 연결몸체(300)의 복수의 유입홀(340)은, 2개의 제1유입홀(340)이 서로 마주보게 형성되고, 2개의 제2유입홀(340')은 상기 제1유입홀(340)과 어긋나는 위치에 형성된다. The plurality of inlet holes 340 of the connection body 300 are formed so that two first inlet holes 340 face each other, and the two second inlet holes 340' are the first inlet holes 340 ) Is formed in a position that deviates from it.

상기 제1유입홀(340)은 상부에 형성되고, 제2유입홀(340')은 하부에 이격되어 형성되는 것이다.The first inflow hole 340 is formed on the upper side, and the second inflow hole 340 ′ is formed to be spaced apart from the bottom.

따라서 1쌍의 제1유입홀(340)과 또 다른 1쌍의 제2유입홀(340') 간에 위치가 상이하되 각기 90도 간격으로 배열되며, 이렇게 어긋나게 배열됨으로서 1쌍의 제1유입홀(340) 간의 간격과 나머지 1쌍의 제2유입홀(340') 간의 간격이 넓게 형성될 수 있어 파손의 위험성이 방지될 수 있다. Therefore, the positions of the first inflow holes 340 of one pair and the second inflow holes 340' of another pair are different, but they are arranged at intervals of 90 degrees, and are arranged so as to be offset. Since the gap between 340 and the gap between the remaining pair of second inflow holes 340 ′ may be formed wide, the risk of damage may be prevented.

즉, 인접된 유입홀(340,340')들 간의 간격을 적정하게 이격시킬 수 있어 내구성이 강화될 수 있는 것이다. That is, the distance between the adjacent inlet holes 340 and 340 ′ can be properly spaced, thereby enhancing durability.

만약 인접된 유입홀(340,340')들 간의 간격이 너무 근접할 경우 천공 과정에서 각 유입홀(340,340') 사이의 이격부위가 찢어지면서 파손될 우려가 있기 때문이다. This is because if the distance between the adjacent inlet holes 340 and 340' is too close, there is a risk that the spaced portion between each inlet hole 340 and 340' is torn and damaged during the drilling process.

제2회전부재(400)는, 상기 연결몸체(300)의 외주면에 회전가능하게 결합되도록 양단이 관통되는 회전결합부(410)가 형성되고, 상기 회전결합부(410)에 직각방향으로 통하도록 형성되며 외부와 통하는 개구공(422)을 갖는 소켓 결합부(420)가 형성된 것이며, 상기 제1회전부재(200)의 회전방향에 직각되는 방향으로 회전된다.
