Description

잠금 유압장치Locking hydraulics

본 고안은 일반 작업장에서 사용되는 유압장치에 관한 것으로, 더욱 상세하게는 에어실린더와 대칭으로 유압실린더를 설치하여 유압실린더의 비압축성을 이용한 잠금유압장치에 관한 것이다. 유압장치(1)는 첨부도면 제1도와 같이 형성된 것으로, 일반 작업장에서 무거운 물체나 기계 장치를 상층부에 있는 작업장으로 들어올린 상태에서 작업해야 될 경우 사용하는 장치이다. 에어실린더(2)의 받침대(3) 위에 무거운 물체(12)를 올려놓은 상태에서 상방으로 들어주는 과정은 다음과 같다. 공기공급원(5)에서 공기를 보내면 공기는 배관(6)을 타고 에어실린더(2)의 하구부(7)에 유입되고, 이때 압축부(11)의 하단에 공기(4)가 차면서 압축부(11)는 상방으로 상승하게 되며, 압축부(11)의 상단에 있던 공기(4)는 상구부(8)를 통해 배관(6)으로 유출되어 외부로 빠져나오게 되는 것이다. 여기서, 압축부(11)는 에어실린더(2)의 내측 상단면에 접촉할 때까지 상승하게 되고, 내측상단면에 접촉하게 되면 에어실린더(2)의 작동이 멈추게 된다. 또한, 작업이 종료되어 받침대(3)를 하방으로 하강시킬 때는 솔레노이드밸브(9)를 작동시켜 공기공급원(5)에서 공기가 공급되는 배관(6)의 위치가 바뀌게 되어 상구부(8)에 공기(4)가 유입되고, 동시에 압축부(11)의 하단에 있던 공기(4)는 하구부(7)로 빠져나오면서 외부로 유출되는 것이다. 솔레노이드밸브(9)는 전기로 작동되는 것으로, 공기가 공기공급원(5)에서 에어실린더(2)로 유입될 때 방향을 제어하는 것이다.The present invention relates to a hydraulic device used in a general workplace, and more particularly, to a lock hydraulic device using the incompressibility of the hydraulic cylinder by installing the hydraulic cylinder symmetrically with the air cylinder. The hydraulic device 1 is formed as shown in FIG. 1 and is a device used when a heavy object or a mechanical device is to be lifted to a workshop located in an upper floor in a general workplace. The process of lifting upward in a state where the heavy object 12 is placed on the pedestal 3 of the air cylinder 2 is as follows. When air is sent from the air supply source 5, the air enters the inlet 7 of the air cylinder 2 through the pipe 6, and at this time, the air 4 is filled at the lower end of the compression part 11 and the compression part ( 11 is raised upwards, the air 4 at the upper end of the compression unit 11 is discharged to the pipe 6 through the upper sphere 8 to exit to the outside. Here, the compression unit 11 is raised until it comes in contact with the inner upper end surface of the air cylinder (2), the contact with the inner upper end surface is stopped the operation of the air cylinder (2). In addition, when the work is completed and the pedestal 3 is lowered downward, the solenoid valve 9 is operated to change the position of the pipe 6 through which the air is supplied from the air supply source 5 so that the air in the upper opening 8 can be changed. (4) flows in, and at the same time, the air 4 at the lower end of the compression section 11 flows out into the inlet 7 and flows outward. The solenoid valve 9 is electrically operated to control the direction when air enters the air cylinder 2 from the air supply 5.

그러나, 종래의 유입장치(1)는 받침대(3)로 무거운 물체(12)를 들어줄 경우 공기압이 약해지거나 없어지면 받침대(3)에 올려진 물체(12)의 하중을 지탱하지 못하여 받침대(3)가 하방으로 하강하게 되는 경우가 빈번히 발생하여 작업할 때 위험성이 상존되는 문제가 있었다. 본 고안은 상기한 종래의 유압장치가 지닌 문제를 해결하기 위하여 안출된 것으로, 에어실린더와 대칭되게 유압실린더를 설치하여 에어실린더와 유압실린더가 일체로 작동되도록 한 잠금 유압장치를 제공하고자 함에 고안의 목적이 있다. 상기와 같은 목적을 실현하기 위한 본 고안은 에어실린더와 대칭하여 유압실린더를 설치하되, 작동할 때 같이 움직이도록 일체로 설치하며, 유압실린더의 축을 받침대와 결합하고, 유압실린더의 외주면에 상구부와 하구부를 형성하며, 상구부와 하구부에 송유관을 설치하며, 송유관의 중간부에 체크밸브를 설치하고, 체크밸브와 공기공급원 사이에 파일롯관을 설치한 것이다. 따라서, 본 고안은 에어실린더가 상승된 상태에서 에어실린더의 축이 비상시에 하강되는 것을 방지할 수 있는 것이다.However, the conventional inflow apparatus 1 does not support the load of the object 12 mounted on the pedestal 3 when the air pressure is weakened or lost when the heavy object 12 is lifted into the pedestal 3. There is a problem that the risks are constantly present when the work is frequently descended downward. The present invention was devised to solve the problems of the conventional hydraulic device, and to provide a locking hydraulic device to operate the air cylinder and the hydraulic cylinder integrally by installing the hydraulic cylinder symmetrically with the air cylinder. There is a purpose. The present invention for realizing the above object is to install the hydraulic cylinder symmetrically to the air cylinder, to be installed integrally to move together when operating, to combine the shaft of the hydraulic cylinder with the pedestal, and to the upper circumference of the hydraulic cylinder The inlet is formed, and the oil pipe is installed in the upper and lower inlets, a check valve is installed in the middle of the oil pipe, and a pilot pipe is installed between the check valve and the air supply source. Therefore, the present invention can prevent the axis of the air cylinder from falling in an emergency while the air cylinder is raised.

본 고안을 첨부된 예시도면 제2도에 의하여 상세히 설명하면 다음과 같다. 본 고안은 에어실린더(18)와 대칭하여 유압실린더(20)를 설치하고, 유압실린더(20)의 축(24') 상단부를 받침대(22)의 하단면에 결합하며, 유압실린더(20)의 외측면에 송유관(36)을 각각 상구부(38')와 하구부(40')에 설치하고, 송유관(36)의 일측에 체크밸브(14)를 설치하며, 체크밸브(14)와 공기공급원(26) 사이에 파일롯관(34)을 설치하여 구성한 잠금 유압장치이다. 상기와 같이 구성된 잠금 유압장치는 첨부도면 제2도와 같이 도시될 수 있는데, 유압실린더(20)를 에어실린더(18)와 대칭하여 설치하고, 유압실린더(20)의 축(24')은 받침대(22)와 결합 설치한 것이다. 공기공급원(26)에서 공기가 배관(28)을 따라 유입되면 공기는 에어실린더(18)의 하구부(40)에 흘러들어가 에어실린더(30)의 압축부(30)를 밀어내면서 받침대(22)를 상방으로 상승시키고, 동시에 파일롯관(34)에 공기압이 형성되면 체크밸브(14)는 공기압에 의해 개방되므로 유압실린더(20)의 압축부(30')는 하구부(40')에 유압이 작용하여 상방으로 에어실린더(18)의 압축부(20)와 동시에 상방으로 상승하게 된다. 여기서 유압실린더(18)의 압축부(30') 상단에 있던 기름은 상구부(38')를 통해 유출되어 체크밸브(14) 쪽으로 흐르면서 하구부(40')로 순환한다. 파일롯관(34)에 공기압이 없을 경우에는 체크밸브(14)가 닫혀서 유압실린더(20)의 압축부(30')는 하강되지 않고 그 위치에서 멈추게 된다. 파일롯관(34)을 통해서 체크밸브(14)에 공기압이 전달되기만 하고, 체크밸브(14)의 내부에 있는 오일은 파일롯관(34)으로 역유입되지 않도록 성형된 것이다. 즉, 체크밸브(14)는 정해진 방향과 반대되는 방향을 차단하는 것으로 파일롯관(34)에서 유입되는 공기만 체크밸브(14) 쪽으로 흐르고, 체크밸브(14)내에 있는 오일은 파일롯관(34)에 흐르지 못하도록 막는 기능을 갖고 있다.When the present invention is described in detail with reference to the accompanying drawings 2 as follows. The present invention installs the hydraulic cylinder 20 in symmetry with the air cylinder 18, the upper end of the shaft 24 'of the hydraulic cylinder 20 is coupled to the bottom surface of the pedestal 22, the hydraulic cylinder 20 An oil supply pipe 36 is provided on the outer surface at the upper opening 38 'and the lower hole 40', respectively, and a check valve 14 is installed at one side of the oil supply pipe 36, and the check valve 14 and the air supply source are provided. It is the locking hydraulic apparatus comprised by installing the pilot pipe 34 between 26. The locking hydraulic device configured as described above may be illustrated as shown in FIG. 2, wherein the hydraulic cylinder 20 is symmetrically installed with the air cylinder 18, and the shaft 24 ′ of the hydraulic cylinder 20 is a pedestal ( 22) in combination with the installation. When air is introduced from the air supply source 26 along the pipe 28, the air flows into the inlet 40 of the air cylinder 18 and pushes the compression part 30 of the air cylinder 30 to support the base 22. Is raised upward, and at the same time, when air pressure is formed in the pilot pipe 34, the check valve 14 is opened by the air pressure, so that the compression part 30 'of the hydraulic cylinder 20 has a hydraulic pressure in the inlet 40'. It acts and rises upward simultaneously with the compression part 20 of the air cylinder 18 upwards. Here, the oil at the upper end of the compression part 30 'of the hydraulic cylinder 18 flows out through the upper mouth part 38' and flows toward the check valve 14 to circulate to the lower part 40 '. If there is no air pressure in the pilot pipe 34, the check valve 14 is closed so that the compression section 30 'of the hydraulic cylinder 20 is not lowered and stops at that position. Only the air pressure is transmitted to the check valve 14 through the pilot pipe 34, the oil inside the check valve 14 is molded so as not to flow back into the pilot pipe (34). That is, the check valve 14 blocks the direction opposite to the predetermined direction, and only the air flowing from the pilot pipe 34 flows toward the check valve 14, and the oil in the check valve 14 passes through the pilot pipe 34. It has a function to prevent it from flowing.

따라서, 본 고안은 에어실린더(18)와 대칭하여 유압실린더(20)를 설치하고, 유압실린더(20의 외주면에 상구부(38')와 하구부(40')를 형성하여 각각 송유관(36)을 설치하며, 송유관(36)의 중간부에 체크밸브(14)를 2개 설치하되, 2개의 체크밸브(14)와 공기공급원(26) 사이에 파일롯관(34)을 설치하여 구성된 것으로 에어실린더가 상승된 상태에서 에어실린더의 축이 비상시에 하강되는 것을 방지할 수 있는 효과가 있다.Therefore, the present invention is installed symmetrical with the air cylinder 18, the hydraulic cylinder 20, and the upper cylinder 38 'and the lower portion 40' on the outer circumferential surface of the hydraulic cylinder 20, respectively, the oil pipe 36 And install two check valves (14) in the middle of the oil supply pipe (36), and install a pilot pipe (34) between the two check valves (14) and the air supply source (26). There is an effect that can prevent the axis of the air cylinder is lowered in an emergency in the rising state.
