유압탱크의 비상공급용 흡입관 취부구조Suction pipe mounting structure for emergency supply of hydraulic tank

본 고안은 유압탱크의 비상공급용 흡입관 취부구조에 관한 것으로, 더욱 상세하게는 유압식 중장비의 유압탱크의 배플판에 의해 탱크내부가 리턴부와 흡입부로 구분되지 않는 소형탱크 또는 휠타입 굴삭기의 주행시 오일쿨러 등의 파손으로 인한 비상흡입부가 필요한 경우, 리턴부에 비상용 흡입관을 설치하여 귀환되는 작동유가 흡입부를 통해 곧바로 펌프에 유입되는 것을 방지할 수 있도록 한 유압탱크의 비상공급용 흡입관 취부구조에 관한 것이다.The present invention relates to an inlet pipe mounting structure for emergency supply of a hydraulic tank, and more particularly, oil in driving a small tank or wheel type excavator in which the tank inside is not divided into a return part and a suction part by a baffle plate of a hydraulic tank of a hydraulic heavy equipment. When emergency suction part is necessary due to damage of cooler, etc., it is related with emergency suction suction pipe installation structure of hydraulic tank which installed emergency suction pipe at return part to prevent returning hydraulic oil from flowing into pump through suction part immediately. .

제1도는 종래 기술에 의한 유압탱크의 흡입관 취부구조의 개략도이다.1 is a schematic diagram of a suction pipe mounting structure of a hydraulic tank according to the prior art.

도시된 바와같이, 유압탱크(1) 내부의 중간 소정위치에 설치된 배플판(2)의 일측에 귀환되는 작동유를 필터링하는 오일필터(3)가 내설되며, 상기 배플판(2)의 타측에 펌프에 연결되는 흡입관(4) 입구측에 작동유에 포함된 먼지, 이물질 등의 불순물을 여과하는 스트레이너(5)가 설치된다.As shown, the oil filter (3) for filtering the hydraulic oil returned to one side of the baffle plate (2) installed in the intermediate predetermined position inside the hydraulic tank (1) is built-in, the pump on the other side of the baffle plate (2) At the inlet side of the suction pipe 4 connected to the strainer 5 is installed a filter for filtering impurities, such as dust, foreign matter contained in the working oil.

그러나, 휠타입 굴삭기의 주행중 오일쿨러 등의 파손으로 인해 작동유의 손실이 발생되는 경우, 안전한 조향이 가능하도록 메인 작동유 라인에 대해 별도의 조향 공급라인을 형성하게 되는데, 이때 유압탱크의 배플판을 중심으로 하여 작동유가 귀환되는 리턴부와 펌프에 의해 작동유를 흡입하는 흡입부로 구분할 때 유압탱크의 용량이 작아 비상용 흡입부를 통상의 흡입부에 설치하기가 곤란하여 리턴부에 설치하는 경우, 작동유 귀환시 작동유에 포함된 먼지, 이물질 등이 펌프로 곧바로 흡입되어 작동유 유로를 순환될 때 작동유 공급라인 부품에 손상을 초래하는 것이다.However, when hydraulic oil is lost due to breakage of the oil cooler, etc. while driving the wheel type excavator, a separate steering supply line is formed for the main hydraulic oil line so that safe steering can be performed, wherein the baffle plate of the hydraulic tank is centered. When the hydraulic oil is divided into a return part for returning hydraulic oil and a suction part for sucking hydraulic oil by a pump, it is difficult to install the emergency suction part in a normal suction part because the capacity of the hydraulic tank is small. The dust and foreign matter contained in the pump are sucked directly into the pump and cause damage to the hydraulic oil supply line components when the hydraulic oil circulation is circulated.

따라서, 본 고안의 목적은, 유압탱크가 작아 배플판에 의해 리턴부와 흡입부의 구분이 되지 않을 때 또는 주행중 오일 손실로 인해 오일 흡입이 필요한 경우, 유압탱크의 리턴부에 유입된 작동유가 곧바로 펌프로 유입되는 것을 차단하도록 비상흡입관을 설치하여 작동유에 포함된 먼지 등의 불순물로 인하여 유압부품의 손상되는 것을 방지할 수 있도록 한 유압탱크의 비상공급용 흡입관 취부구조를 제공하는 것이다.Therefore, the object of the present invention is that when the hydraulic tank is small and the baffle plate does not distinguish between the return part and the suction part, or when oil suction is required due to oil loss while driving, the hydraulic fluid flowing into the return part of the hydraulic tank is pumped immediately. It is to provide an emergency supply suction pipe mounting structure of the hydraulic tank to prevent the damage of the hydraulic components due to the impurities such as dust contained in the hydraulic fluid by installing an emergency suction pipe to block the flow into.
