자주식 중장비(R)의 본체 상부에 파이롯트 페달(10)에 의하여 작동되는 윈치모터(20)를 윈치드럼(21)의 내부에 설치하고 윈치드럼(21)에 감겨진 와이어 로우프(22)를 붐(30)의 상단에 장착된 붐 롤러(31)를 통하여 인입,출시킬 수 있게하고 붐(30)의 중단에는 암(40)을 설치하며 암(40)의 선단에는 그랩(50)을 설치하여 각각의 유압실린더(32)(41)(51)에 의하여 작동시킬 수 있게 한 구조이다.The winch motor 20 operated by the pilot pedal 10 on the main body of the self-propelled heavy equipment R is installed in the winch drum 21, and the wire rope 22 wound on the winch drum 21 is boomed. It is possible to draw in and out through the boom roller 31 mounted at the upper end of the 30, and to install the arm 40 at the end of the boom 30, and to install the grab 50 at the tip of the arm 40 It is a structure that can be operated by the hydraulic cylinder (32, 41, 51).
상기한 와이어 로우프(22)가 감겨진 윈치드럼(21)의 하단에는 힌지축(23)을 중심으로 상단은 로우프 가이드롤러(24),하단은 스프링(25)을 장착하여 와이어 로우프(22)를 인입,출시 제어할 수 있게 하였다.At the lower end of the winch drum 21 on which the wire rope 22 is wound, a rope guide roller 24 is mounted on the top of the hinge shaft 23 and a spring 25 is mounted on the lower end of the winch drum 21 to connect the wire rope 22. It can be controlled to pull in and release.
또한 윈치모터(20)를 작동시키는 파이롯트 페달(10)의 하단에는 정회전 포트(1)와 역회전 포트(2)가 구비되고 펌프(3)의 유량은 메인컨트롤 밸브(4)를 통하여 릴리프 밸브(5)가 내장된 윈치모터(20)로 통하게 된 것이다.In addition, the lower end of the pilot pedal 10 for operating the winch motor 20 is provided with a forward rotation port (1) and a reverse rotation port (2) and the flow rate of the pump (3) through the main control valve (4) (5) will be led to the built-in winch motor (20).
도면중 미설명부호 (6)은 목재이고 (7)(7')(8)(8')는 메인컨트롤 밸브(4)의 포트이다.In the figure, reference numeral 6 denotes wood, and 7, 7 ', 8, and 8' are ports of the main control valve 4.
이와같이된 본 발명은 자주식 중장비(R)를 구동시켜 벌목현장의 근접거리까지 접근시키지 않고 일정한 거리를 유지한 상태에서 벌목된 목재(6)가 위치한 방향으로 붐(30)의 상단이 향하도록 조절하고 파이롯트 페발(10)을 앞쪽을 밟으면 도 3 에 도시된 바와같이 하단에 정회전 포트(1)를 통하여 펌프(3)에서 토출된 유량을 메인컨트롤 밸브(4)의 포트(8)로 압력을 전달하게되고 이 압력은 메인컨트롤 밸브(4)의 스풀을 작동시켜 윈치모터(20)로 연결되는 포트(8')로 작동유를 전달하게 되어 윈치모터(20)을 정회전시켜 윈치드럼(21)의 와이어 로우프(22)를 풀어주게 되며 이때 와이어 로우프(22)는 붐(30)을 따라 상단에 장착된 붐 롤러(31)에 안내되어 작업자가 와이어 로우프(22)를 벌목된 목재(6)까지 이동시켜 와이어 로우프(22)의 끝단을 목재(6)에 묶어서 고정시킨다.The present invention as described above is driven to drive the self-propelled heavy equipment (R) so that the top of the boom 30 in the direction in which the wood lumber 6 is located while maintaining a constant distance without approaching the proximity of the logging site and When the pilot pedal 10 is stepped forward, the flow rate discharged from the pump 3 through the forward rotation port 1 at the bottom as shown in FIG. 3 transmits the pressure to the port 8 of the main control valve 4. This pressure is to operate the spool of the main control valve (4) to transfer the hydraulic fluid to the port (8 ') connected to the winch motor 20 to rotate the winch motor 20 forward of the winch drum 21 The wire rope 22 is released, at which time the wire rope 22 is guided along the boom 30 to the boom roller 31 mounted at the top so that the worker moves the wire rope 22 to the felled wood 6. The end of the wire rope 22 is tied to the wood 6 and fixed.
그리고 목재(6)와 자주식 중장비(R)의 거리에 따라 붐(30)의 높이를 유압실린더(32)로 상승 또는 하강시켜 조절하고 붐(30)의 중단에 장착된 암(40)과 선단의 그랩(50)을 각각의 유압실린더(41)(51)로 조절하여 암(30)을 지지할 수 있는 자세로 조절시킨 후 목재(6)를 집하장으로 견인하기 위하여 파이롯트 페달(10)의 뒤쪽을 밟으면 하단에 역회전 포트(2)를 통하여 펌프(3)에서 토출된 유량을 메인컨트롤 밸브(4)의 포트(7)로 압력을 전달하게되고 이 압력은 메인컨트롤 밸브(4)의 스풀을 작동시켜 윈치모터(20)로 연결되는 포트(7')로 작동유를 전달하게 되어 윈치모터(20)을 역회전시켜 윈치드럼(21)의 와이어 로우프(22)를 감아주게 되어 목재(6)의 견인작업을 수행할 수 있는 것이다.And according to the distance of the wood (6) and self-propelled heavy equipment (R) to adjust the height of the boom (30) by raising or lowering the hydraulic cylinder (32) of the arm (40) and the tip of the end mounted on the stop of the boom (30) Adjust the grab 50 with the respective hydraulic cylinders 41 and 51 to adjust the posture to support the arm 30, and then move the rear of the pilot pedal 10 to tow the wood 6 to the storage. When pressed, the flow rate discharged from the pump 3 through the reverse rotation port 2 at the bottom transfers the pressure to the port 7 of the main control valve 4, and this pressure operates the spool of the main control valve 4. The hydraulic fluid is transferred to the port 7 'which is connected to the winch motor 20 so that the winch motor 20 is rotated in reverse to wind the wire rope 22 of the winch drum 21 to tow the wood 6. You can do it.
상기와 같은 작업을 수행하면서 와이어 로우프(22)를 인출 및 인입시에 안전율을 고려하여 윈치모터(20)의 내부에는 릴리프 밸브(5)가 내장되어 있으며, 윈치모터(20)는 목재(6)의 견인속도를 자유롭게 조절할 수 있도록 가변형 피스톤 모터를 적용하였다.While performing the above operation, the relief valve 5 is built into the winch motor 20 in consideration of the safety factor when the wire rope 22 is drawn out and drawn in, and the winch motor 20 is made of wood 6. A variable piston motor is applied to freely adjust the traction speed of the engine.
또한 목재(6)를 견인하기 위하여 와이어 로우프(22)를 인출,인입시키는 윈치드럼(21)은 도 2 에 도시된 바와같이 윈치드럼(22)의 하단에 장착된 힌지축(23)을 중심으로 상단에는 로우프 가이드롤러(24)가 장착되어 힌지축(23)의 하단에 착설된 스프링(25)의 탄발력에 의하여 와이어 로우프(22)가 윈치드럼(21)에 인출되거나 인입될 때 와이어 로우프(22)를 로우프 가이드롤러(24)가 스프링(25)의 장력에 의하여 압착하면서 와이어 로우프(22)가 겹치거나 꼬이지 않게 위치를 제어하면서 감아주고 풀어주어 와이어 로우프(22)가 윈치드럼(21)에 일정하게 정렬시킬 수 있게 하였다.In addition, the winch drum 21 which draws in and pulls out the wire rope 22 to pull the wood 6 is centered on the hinge shaft 23 mounted at the bottom of the winch drum 22 as shown in FIG. 2. The rope guide roller 24 is mounted on the upper end of the wire rope 22 when the wire rope 22 is drawn out or drawn in to the winch drum 21 by the elastic force of the spring 25 mounted on the lower end of the hinge shaft 23. 22, while the rope guide roller 24 is pressed by the tension of the spring 25, while the wire rope 22 is controlled and wound while controlling the position so that the wire rope 22 does not overlap or twist, the wire rope 22 is wound on the winch drum 21. It was able to align regularly.
그리고 본 발명은 붐(30)과 암(40)에 연결,설치된 그랩(50)을 각각의 유압실린더(32)(41)(51)를 작동시켜 집하장에 견인된 목재(6)를 집어서 일측에 정리하여 적재하거나 운송차량에 탑재시에도 사용할 수 있는 것이다.And the present invention is connected to the boom 30 and the arm 40, the grab 50 is installed to operate the respective hydraulic cylinders (32, 41, 51) to pick up the wood (6) towed to the storage box one side It can also be used to load them on a truck or load them into a transport vehicle.
본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
그러므로 본 발명은 산림지역에서 벌목 후 수행되는 목재의 견인 및 운송시에 추가적인 산림훼손을 방지하는 자연환경 친화적인 장비를 제공할 수 있고 또한 벌목현장까지 근접,진입하지 않고 손쉽게 목재 견인작업을 수행할 수 있는 등의 효과가 있는 것이다.Therefore, the present invention can provide a natural environment-friendly equipment to prevent additional forest damage during the towing and transportation of wood carried out after logging in the forest area, and also can easily perform timber towing work without entering or entering the logging site.
