Therefore, it takes a lot of manufacturing costs, in particular, there was a problem such as cooling performance is lowered.
본 고안은 상기한 제반문제점을 해결하기 위한 것으로서, 본 고안은 유압식 중장비의 작동유의 압력을 이용하여 에너지를 효율적으로 사용할 수 있을 뿐만 아니라, 냉각성능을 향상시킬 수 있는 유압식 중장비의 냉각장치를 제공하는데 그 목적이 있다.The present invention is to solve the above-mentioned problems, the present invention is to use the pressure of the hydraulic oil of the hydraulic heavy equipment to efficiently use energy, to provide a cooling device of the hydraulic heavy equipment that can improve the cooling performance. The purpose is.
상기한 목적을 달성하기 위해 본 고안은 유압식 중장비의 엔진을 냉각시키는 것에 있어서, 메인콘트롤 밸브(1)와 오일쿨러(2) 사이에 엔진(3)에서 발생되는 열을 냉각시키는 냉각수단이 설치된 것이다.In order to achieve the above object, the present invention is to cool the engine of the hydraulic heavy equipment, cooling means for cooling the heat generated in the engine (3) between the main control valve (1) and the oil cooler (2) is installed. .
이하, 본 고안의 일실시예를 첨부도면 제2도 및 제3도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3 of the accompanying drawings.
제2도는 본 고안을 나타낸 개략구성도이고, 제3도는 제2도의 A부분 확대종단면도로서, 유압식 중장비의 메인콘트롤 밸브(1)와 오일쿨러(2) 사이에 엔진(3)에서 발생되는 열을 냉각시키기 위한 냉각수단이 설치되고, 냉각수단이 전방에는 상기 엔진(3)에 축(4)으로 연결된 냉각팬(5)이 설치된다.FIG. 2 is a schematic configuration diagram showing the present invention, and FIG. 3 is an enlarged longitudinal sectional view of the portion A of FIG. 2, which shows heat generated by the engine 3 between the main control valve 1 and the oil cooler 2 of the hydraulic heavy equipment. Cooling means for cooling the air is installed, the cooling means 5 is provided with a cooling fan (5) connected to the engine (3) in front of the engine (3).
또한, 냉각수단은 본체(6) 내부에 메인콘트롤 밸브(1)에서 탱크(7)로 복귀되는 작동유에 따라 회전하는 기익(8)이 내장되고, 상기 본체(6)와 기익(8)을 관통하여 축(4a)이 설치되며, 축(4a)의 끝단에는 상기 기익(8)의 회전과 동시에 회전하여 외부의 공기를 흡입시키는 팬(5a)이 장착되고, 상기 본체(6) 내부와 축(4a)의 중앙부에는 각각 축(4a)의 회전을 지지하는 베어링(9)과 회전지지부재(10)가 장착되어 구성된다.In addition, the cooling means has a blade (8) is built in the main body (6) to rotate in accordance with the operating oil returned from the main control valve (1) to the tank (7), and penetrates the main body (6) and the blade (8) The shaft 4a is installed, and at the end of the shaft 4a is mounted a fan 5a which rotates simultaneously with the rotation of the blade 8 to suck outside air, and the inside of the main body 6 and the shaft ( In the central portion of 4a), a bearing 9 and a rotation supporting member 10 for supporting rotation of the shaft 4a are mounted.
이와 같이 구성된 본 고안은 제2도 및 제3도에 나타낸 바와 같이, 유압식 중장비의 메인콘트롤 밸브(1)와 오일쿨러(2) 사이에 엔진(3)에서 발생되는 열을 냉각시키기 위한 냉각수단이 설치되므로 유압 액츄에이터(도시는 생략함)를 작동한 후 상기 메인콘트롤 밸브(1)에서 탱크(7)로 복귀되는 작동유의 유속 및 압력으로 상기 냉각수단의 본체(6)에 내장된 기익(8)이 회전하게 됨과 동시에, 상기 본체(6)와 기익(8)을 관통하여 설치된 축(4a) 끝단의 팬(5a)이 회전해서 외부의 공기를 흡입하므로 인해 엔진(3)에 발생되는 열을 엔진(3)의 축(4)에 장착된 냉각팬(5)과 함께 이중으로 냉각시킬 수 있어서, 냉각효율을 향상시킬 수 있게 된다.The present invention configured as described above has cooling means for cooling the heat generated by the engine 3 between the oil control unit 1 and the main control valve 1 of the hydraulic heavy equipment, as shown in FIGS. Since it is installed, operating the hydraulic actuator (not shown), the blade (8) built in the main body (6) of the cooling means at the flow rate and pressure of the hydraulic oil returned from the main control valve (1) to the tank (7) At the same time, the fan 5a at the end of the shaft 4a installed through the main body 6 and the blade 8 rotates and sucks external air, thereby causing the engine 3 to heat up. With the cooling fan 5 attached to the shaft 4 of (3), it can cool dually, and it becomes possible to improve cooling efficiency.
뿐만 아니라, 본 고안의 냉각수단을 별도의 동력원 없이 구동하므로 인해 에너지를 대폭 절감시킬 수 있게 된다.In addition, since the cooling means of the present invention is driven without a separate power source, energy can be greatly reduced.
