여기서 본 발명의 실시예를 첨부한 도면을 참조로 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 로딩 시스템은 트럭의 앞부분을 들어올려 리어 데크(rear deck)부를 지면 가까이 낮추어줌으로써, 무한궤도를 갖는 중장비등을 쉽게 적재시키고자 한 것이다.The loading system of the present invention is to lift the front of the truck to lower the rear deck (rear deck) near the ground, to easily load heavy equipment and the like having a caterpillar.

첨부한 도 1은 본 발명에 따른 트럭의 로딩 상태를 나타내는 측면도로서, 트럭의 양측에 메인실린더(16) 및 보조실린더(18)가 전후로 나란히 설치되고, 이 메인실린더(16) 및 보조실린더(18)의 피스톤 하단끝에는 지면에 지지될 수 있는 지지판이 힌지로 장착되어 있다.1 is a side view showing a loading state of a truck according to the present invention, in which the main cylinder 16 and the auxiliary cylinder 18 are installed side by side before and after the main cylinder 16 and the auxiliary cylinder 18. At the lower end of the piston, the support plate, which can be supported on the ground, is hinged.

이때, 상기 트럭의 트랜스미션 사이드쪽에는 오일 펌프를 구동시키기 위한 PTO(10)가 엔진에 물리면서 장착되어, 엔진의 구동과 함께 구동하게 된다.At this time, the PTO 10 for driving the oil pump is mounted on the transmission side of the truck while being bitten by the engine and driven together with the driving of the engine.

또한, 상기 PTO(Power Take Off)(10)에는 유압오일펌프(12)가 연결되어, 상기 PTO(10)의 구동과 함께 유압오일을 펌핑하는 작동을 하게 된다.In addition, the hydraulic oil pump 12 is connected to the power take off (PTO) 10 to operate the pumping hydraulic oil with the drive of the PTO (10).

물론, 오일탱크로부터 유압오일을 펌핑하게 되는 바, 펌핑되는 오일의 불순물이 필터(14)에 의하여 걸러지게 된다.Of course, since the hydraulic oil is pumped from the oil tank, impurities of the pumped oil are filtered by the filter 14.

한편, 첨부한 도 2에 도시한 바와 같이 상기 메인실린더(16) 및 보조실린더(18)를 작동시키기 위하여 유압식 솔레노이드(20)의 일측에 부착된 작동레버를 작동시키게 된다.Meanwhile, as shown in FIG. 2, the operation lever attached to one side of the hydraulic solenoid 20 is operated to operate the main cylinder 16 and the auxiliary cylinder 18.

상기 유압식 솔레노이드(20)에 의한 유압이 각 실린더쪽으로 제공되는 바,그 유압라인상에는 각 실린더의 피스톤 하강시 급하강을 방지하기 위하여 속도조절용 교축밸브(22)가 연결되어 있다.The hydraulic pressure by the hydraulic solenoid 20 is provided to each cylinder, the speed control throttling valve 22 is connected to the hydraulic line on the hydraulic line to prevent the falling of the piston when descending.

또한, 상기 속도조절용 교축밸브(22)와 각각의 실린더 사이의 유압라인상에는 압력조절장치(30)가 설치되어, 지면의 지지력 차이에 의한 차량의 기울기 발생시, 후술하는 바와 같이 상기 각 실린더(16,18)들의 좌우 유압력을 조절해주게 된다.In addition, a pressure regulating device 30 is provided on the hydraulic line between the speed regulating throttling valve 22 and each cylinder, and when the inclination of the vehicle occurs due to the difference in the bearing capacity of the ground, the cylinders 16, 18) to adjust the left and right hydraulic force.

또한, 상기 압력조절장치(30)와 각 실린더(16,18) 사이의 유압라인상에는 각각의 실린더들의 압력을 체크하는 압력계(24) 및 압력스위치(26)가 설치된다.In addition, a pressure gauge 24 and a pressure switch 26 are installed on the hydraulic line between the pressure regulator 30 and each cylinder 16 and 18 to check the pressure of each cylinder.

따라서, 트럭이 한쪽 지면의 지지력 과다 차이로 15°이상 급속한 기울기가 발생하게 되면, 압력스위치(26)가 스위칭되는 바, 이때 좌우측 실린더(16,18)들을 지면으로 강제 하강(들려진 트럭의 앞쪽이 지면으로 원위치되는 하강)시키는 안전장치 작동 솔레노이드(28)가 설치되어 있다.Therefore, if the truck is inclined at an angle of 15 ° or more due to an excessive difference in bearing capacity of one ground, the pressure switch 26 is switched, whereby the left and right cylinders 16 and 18 are forced down to the ground (the front of the lifted truck). The safety device actuating solenoid 28 which descends to this ground is provided.

또한, 상기 실린더(16,18)의 하강시 안전을 위하여 경고등 및 경고음 발생을 위한 램프(42) 및 부져장치(44)가 상기 안전장치 작동 솔레노이드(28)와 연결되어 있다.In addition, a lamp 42 and a buzzer device 44 for generating a warning light and a warning sound for safety when the cylinders 16 and 18 are lowered are connected to the safety device operation solenoid 28.

물론, 상기와 같은 안전장치의 급작스런 작동으로 인한 안전사고 예방을 위하여 안전장치 동작제어용 스위치 패널(미도시됨)이 임의의 장소에 설치된다.Of course, the safety panel operation control switch panel (not shown) is installed in any place in order to prevent safety accidents due to sudden operation of the safety device as described above.

여기서, 첨부한 도 3을 참조로 상기 압력조절장치의 구조와 작동관계를 설명하면 다음과 같다.Here, with reference to the accompanying Figure 3 will be described the structure and operation of the pressure regulator as follows.

상기 압력조절장치(30)는 유압이 공급되는 유입로(31)와, 우측 및 좌측 실린더쪽으로 분기된 유압 경로(32)가 내부에서 서로 연통되어 있는 몸체부(33)와; 상기 유입로(31)에 개폐 가능하게 위치된 중간볼(34)과; 상기 양쪽으로 분기된 유압 경로(32)에 각각 개폐를 위하여 구름 가능하게 위치된 개폐볼(35)로 구성되어 있다.The pressure regulating device 30 includes an inflow passage 31 through which hydraulic pressure is supplied, and a body portion 33 in which hydraulic passages 32 branched toward right and left cylinders communicate with each other therein; An intermediate ball 34 positioned to be opened and closed in the inflow path 31; Consists of the opening and closing ball 35 is positioned so as to enable rolling in the hydraulic path 32 branched to both sides.

더욱 상세하게는, 상기 압력조절장치(30)의 몸체부(33)의 유입로(31)는 상기 속도조절용 교축밸브(22)쪽과 연결되어 있고, 상기 분기된 각 유압경로(32)는 각각 좌우측의 메인실린더(16) 및 보조실린더(18)쪽과 연결되어 있다.More specifically, the inflow path 31 of the body portion 33 of the pressure regulating device 30 is connected to the speed control throttling valve 22 side, and each of the branched hydraulic paths 32 It is connected to the main cylinder 16 and the auxiliary cylinder 18 side on the left and right sides.

특히, 상기 분기된 유압경로(32)에는 오목한 홈(36)이 형성되어 있어서, 상기 개폐볼(35)의 하단부가 삽입 안착되는 동시에 상단은 유입경로(32)의 상부벽면과 소정의 거리로 떨어진 상태가 되고, 상기 중간볼(34)은 유입로(31)를 막으면서 안착됨과 함께 유압에 의하여 밀리면서 유입로(31)가 열려져 유압이 양쪽의 분기된 유압경로(32)로 흐르게 된다.In particular, the branched hydraulic path 32 is formed with a concave groove 36, the lower end of the opening and closing ball 35 is inserted and seated at the same time the upper end is separated from the upper wall surface of the inflow path 32 by a predetermined distance In the state, the intermediate ball 34 is seated while blocking the inflow path 31 and the inflow path 31 is opened while being pushed by the hydraulic pressure so that the hydraulic pressure flows to both branched hydraulic paths 32.

이와 같은 구성으로 이루어진 본 발명에 따른 트럭의 로딩 시스템에 대한 작동관계를 설명하면 다음과 같다.Referring to the operation relationship for the loading system of the truck according to the present invention having such a configuration as follows.

트럭의 캡을 포함하는 앞쪽부분을 들어올기 위하여, 운전자가 클러치를 밝으면(클러치 스위치(40)가 온 됨), PTO릴레이를 거쳐 PTO스위치가 온으로 되고, PTO솔레노이드가 열려서 엔진에 PTO샤프트가 물려지게 된다.To lift the front part containing the truck's cab, when the driver turns the clutch bright (clutch switch 40 is on), the PTO switch is turned on via the PTO relay, and the PTO solenoid is opened to open the PTO shaft to the engine. Will be passed down.

다음으로, 클러치를 뗀 후, 엔진 구동력이 PTO(10)로 전달되어, 상기 오일펌프(12)가 구동하게 되고, 그에따라 오일탱크내의 유압용 오일이 오일펌프(12)의 구동력에 의하여 상기 필터(14)로 여과되면서 상기 유압식 솔레노이드(20)까지 펌핑/순환되어진다.Next, after the clutch is released, the engine driving force is transmitted to the PTO 10, and the oil pump 12 is driven so that the hydraulic oil in the oil tank is driven by the driving force of the oil pump 12. It is pumped / circulated to the hydraulic solenoid 20 while being filtered with 14.

이어서, 운전자가 상기 유압식 솔레노이드(20)의 일측에 있는 작동레버를 상승쪽으로 조작하게 되면, 유압식 솔레노이드는 폐회로가 되어, 상기 오일탱크로 부터 순환된 오일압력이 상기 속도조절용 교축밸브(22)를 통하여 압력조절장치(30)로 가해지게 된다.Subsequently, when the driver operates the operation lever on one side of the hydraulic solenoid 20 to the upward side, the hydraulic solenoid becomes a closed circuit, and the oil pressure circulated from the oil tank is passed through the speed regulating throttle valve 22. It is applied to the pressure regulator (30).

연이어, 상기 압력조절장치(30)를 통과한 유압이 상기 메인실린더(16)와 보조실린더(18)로 공급되어, 메인실린더(16)와 보조실린더(18)의 피스톤이 하강 작동됨과 함께 트럭의 앞쪽부분이 들어올려지게 된다.Subsequently, the hydraulic pressure passing through the pressure regulating device 30 is supplied to the main cylinder 16 and the auxiliary cylinder 18 so that the pistons of the main cylinder 16 and the auxiliary cylinder 18 are lowered and operated. The front part will be lifted up.

이에따라, 트럭의 데크에 지면과 연결되는 이송판을 대고, 중장비가 트럭의 데크 안으로 이동하여, 적재되는 것이다.As a result, the transport deck is connected to the deck of the truck, and the heavy equipment moves into the deck of the truck and is loaded.

한편, 지면(좌우측의 노면)의 차이로 인하여, 차량의 기울림이 발생하게 되면, 상기 압력조절장치(30)의 몸체부(33)내에 있는 중간볼이 기울어지는 방향쪽으로 굴러 기울어지는 쪽의 유압경로(32)를 막게 되고, 그에따라 기울어지는 쪽의 실린더 압력을 증대시켜 트럭의 좌우 평형을 유지시켜준다.On the other hand, when the vehicle is inclined due to the difference in the ground (the road surface on the left and right sides), the hydraulic pressure of the inclined side by rolling in the direction in which the intermediate ball in the body portion 33 of the pressure regulator 30 is inclined The path 32 is blocked, thereby increasing the cylinder pressure on the inclined side to maintain the left and right balance of the truck.

또한, 상기 지면에 대한 트럭의 좌우측 평형이 과다하게 유지될 수 없는 상태, 즉 트럭이 한쪽으로 15°이상 기울어지는 상태에서는, 상기 압력조절장치(30)의 몸체부(33)의 유압경로(32)의 홈(36)에 안착되어 있는 개폐볼(35)이 기울어지는 방향으로 굴러서 기울어지는쪽의 유압경로(32)를 막게 된다.Further, in a state in which the left and right equilibrium of the truck with respect to the ground cannot be maintained excessively, that is, in a state in which the truck is inclined by 15 ° or more to one side, the hydraulic path 32 of the body part 33 of the pressure regulating device 30 is The opening and closing ball 35 seated in the groove 36 of the rolls in the inclined direction to block the hydraulic path 32 of the inclined side.

그에따라, 좌우측 실린더의 압력차이가 과다하면, 이를 상기 압력계(24)의 압력스위치(26)가 감지하여 스위칭되고, 이어서 전류가 안전장치 솔레노이드(28)로흐르게 되며, 동시에 안전장치 솔레노이드(28)가 열리면서 오일을 배출시키게 된다.Accordingly, if the pressure difference between the left and right cylinders is excessive, it is sensed and switched by the pressure switch 26 of the pressure gauge 24, and then a current flows to the safety device solenoid 28, and at the same time the safety device solenoid 28 Will open and drain the oil.

따라서, 트럭 양측의 메인실린더(16)와 보조실린더(18)의 피스톤이 복원 이동을 하게 되고, 결국 트럭은 지면과 수평상태인 본래 위치로 강제 복귀되어, 안전사고를 예방할 수 있게 된다.Accordingly, the pistons of the main cylinders 16 and the auxiliary cylinders 18 on both sides of the truck make a restoring movement. As a result, the truck is forcibly returned to its original position horizontal to the ground, thereby preventing a safety accident.

이상에서 본 바와 같이, 본 발명에 따른 트럭의 로딩 시스템에 의하면, 트럭의 캡을 포함하는 앞쪽을 실린더를 사용하여 들어올려지게 함으로써, 중장비등을 트럭의 데크내로 용이하게 적재시킬 수 있는 편리한 점이 있다.As described above, according to the loading system of the truck according to the present invention, there is a convenience in that heavy equipment and the like can be easily loaded into the deck of the truck by lifting the front including the cap of the truck using a cylinder. .

특히, 본 발명의 로딩 시스템 작동중, 트럭이 지면으로부터 과도하게 비평형상태가 되면, 자동으로 실린더가 강제 복원되는 동시에 트럭이 지면과 수평상태로 복귀되어, 작동중의 안전성을 확보할 수 있는 장점이 있다.In particular, when the truck is excessively unbalanced from the ground during the operation of the loading system of the present invention, the cylinder is automatically forcibly restored and at the same time the truck is returned to the horizontal state with the advantage, ensuring the safety during operation There is this.
