본 고안은 지게차의 위치 가변형 평형추에 관한 것으로서, 본 고안의 구체적 특징은 지게차의 후미에 고정부착되어 지게차가 적재물을 적재할때 차체 평형을 잡아주는 평형추를 필요시 간단한 조작을 통해 평형추 부착부위에서 전, 후측으로 원하는 만큼 평형추의 위치변동을 가능케 함으로서 지게차의 제한된 적재 용량에 관계없이 간단하고 안전하게 많은 적재물을 적재할 수 있도록 한 것이다.The present invention relates to a variable position counterweight of the forklift, and the specific feature of the present invention is a fixed weight attached to the rear of the forklift when the forklift loads the load when the counterweight is attached to the counterweight through a simple operation if necessary By allowing the counterweight to be shifted from the front to the rear as desired, the load can be loaded simply and safely regardless of the forklift's limited loading capacity.

일반적으로 지게차는 적재물을 적재할 수 있는 힘 즉 적재용량별로 구분 사용토록 해놓은 것은 이미 공지된 사실이다.In general, it is already known that forklifts have a capacity to load a load, that is, to use them by load capacity.

그러나 현장에서 공공연하게 이 수칙을 무시하고 적재할 수 있는 용량과 관계없이 지게차 한대로 모든량의 적재작업을 하고 있는 것 또한 현실이라 이로인해 여러가지 문제점이 수반되었는데 예를 들어 1톤까지 적재할 수 있는 지게차로 1톤 보다 무거운 적재물을 들어 올릴 경우 차체의 뒷바퀴가 지면과 떨어지면서 위로 들려 차체중심이 상실되어 심하게 요동 안전한 주행과 하역 작업이 불가능 할 뿐 아니라 자칫 안전사고가 발생될 우려가 있는 문제점이 있으며 작업시간이 느려 작업 능률도 떨어지고 그리고 위와 같은 문제점을 보완키 위해 통상 보조 평형추를 많이 사용하고 있는데 이 방법의 경우 증가되는 적재물의 무게보다 더 무거운 별도의 금속재 보조평형추를 도면 제4도에 도시된 바와 같이 바퀴(10) 체결봉(11)에 보조 평형추(9)를 끼워 너트(12)로 조여 부착시켜 지게차의 평형을 맞춘후 적재사업을 해야되는 관계로 보조 평형추는 항상 준비, 보관해야되는 번거로움이 따랐고 작업전과 작업완료후 지게차의 정상적인 주행을 위해 반드시 뒷바퀴에 부착 해놓은 보조 평형추를 제거해야되는데 이 착탈 작업에 많은 시간이 소요되는 번거로운 결점도 있었다.However, it is also a reality that all the loading work is carried out by one forklift regardless of the capacity that can be loaded in the field regardless of this rule openly. Therefore, forklift can load up to 1 ton. If you lift a load that is heavier than 1 ton, the rear wheel of the body falls off the ground and lifts up, resulting in a loss of the center of the vehicle. In order to compensate for the above problems, the auxiliary counterweights are commonly used to compensate for the above problems. In this case, a separate metal auxiliary counterweight is shown which is heavier than the weight of the increased load. Insert the auxiliary counterweight (9) into the wheel (10) fastening rod (11) as shown As the balance of the forklift has to be carried out after tightening it with (12), the auxiliary counterweight has always had to be prepared and stored.The auxiliary weight attached to the rear wheel must be attached for the normal operation of the forklift before and after work. Counterweights have to be removed, which is a cumbersome drawback that takes a long time.

본 고안은 위와 같은 종래의 결점을 해결키 위해 안출 한것으로서 첨부된 도면에 의거 보다 구체적으로 상세히 설명하면 다음과 같다.The present invention has been made in order to solve the above-mentioned drawbacks as described in more detail based on the accompanying drawings as follows.

지게차(1) 후미의 지지부재(2)에 고정 부착된 통상의 지게차의 평형추(4)에 있어서, 지지부재(2) 양측에 계산된 길이 만큼 안내로(3)(3A)를 형성하고 평형추(4)양측에 안내홈(5)(5A)을 요설시켜 서로 결합시킨후 지지부재(2)상면부 중간에 유압실린더(7)를 고정하고 실린더 롯드(8)는 평형추(4) 중간 부분에 부착하여 통상의 메인 펌프(도면생략)동력으로 작동케한 구조이다.In the counterweight 4 of the conventional forklift fixedly attached to the support member 2 at the rear of the forklift 1, guide paths 3 and 3A are formed on the support member 2 on both sides, and the balance is formed. Guide grooves (5) and (5A) are provided on both sides of the weight (4), and then coupled to each other, and then the hydraulic cylinder (7) is fixed in the middle of the upper surface of the support member (2), and the cylinder rod (8) is in the middle of the counterweight (4). It is attached to the part and operated by normal main pump (not shown) power.

이와 같이 구성된 본 고안은 적재 작업중에 작업중인 지게차의 적재할 수 있는 용량 보다 더 무거운 짐을 적재하고저 할 경우 운전석내에 구비되어 메인 펌프(도면 생략)와 유압실린더에 연결된 작동 스위치(도면 생략)를 동작시키면 메인 펌프의 동력에 의해 유압실린더가 작동되고 실린더 롯드(8)가 외측으로 빠지면서 평형추(4)를 동시에 외측으로 밀어 내어 평형추 이동이 가능한데 이때 작동스위치로 평형추를 원하는 폭만큼 외측으로 이동할수도 있어 적재물의 무게와 비교 계산하여 평형추의 위치 변동을 하면 일종의 지렛대 원리에 의해 적재물을 적재하므로 인해 지게차의 뒷바퀴가 위로 들리거나 요동이 전혀 없어 지게차의 주행과 적재물 하역작업을 안전하게 할수가 있어 보조 평형추(9)를 별도로 준비하여 부착하지 않아도 되어 보조 평형추의 착탈 작업에 불필요한 시간 낭비가 전혀 없어 적재물의 적재작업을 신속 편리하게 간단히 할수가 있는 이점을 얻을 수가 있고, 이로인해 적재작업 능률도 향상시킬 수 있으며 또한 현장의 지면이 조금 물러도 지게차 평형이 정확해 지게차에 짐을 적재한 상태에서도 출발 할때나 주행중에 바퀴가 빠질 우려도 없고 그리고 지게차의 작업 종료후 도로로 주행 할때는 운전석 내에 구비된 평형추 원위치 복귀용 스위치(도면 생략)를 눌러 주면 평형추의 작동 역순으로동작되어 정확하게 지게차 후미에 평형추(4)가 밀착된 상태로 복귀되어 지게차의 평형이 맞아 떨어져 안전한 주행을 할수가 있고, 또 평형추(4)는 안내로(3)(3A)에 상, 하측과 좌, 우측에서 지지 슬라이딩 되게 접속되어 있어 작업중에 평형추가 이탈될 염려가 전혀 없는 특징도 있을 뿐 아니라 별도로 보조 평형추를 준비 보관하지 않아도 되므로 보관할때 야기되는 번거로움이 없는등 실용성이 좋은 것이다.In this way, this invention is designed to be installed in the driver's seat to operate the operation switch connected to the main pump (not shown) and the hydraulic cylinder (not shown) when loading a heavier load than the capacity of the forklift truck in operation during the loading operation. Then, the hydraulic cylinder is operated by the power of the main pump and the cylinder rod 8 is pulled outward, and the counterweight 4 can be pushed outward at the same time to move the counterweight. When the counterweight position is calculated by comparing with the weight of the load, the load is loaded according to the principle of lever, so that the rear wheel of the forklift is lifted up or there is no shaking, so that the forklift can safely move and unload the load. Counterweights (9) do not need to be prepared and attached separately There is no waste of unnecessary time for detaching work, which makes it possible to quickly and conveniently load the loads, which improves the efficiency of loading work, and the forklift balance is accurate even when the ground is slightly receded. Even when the forklift is loaded, there is no fear that the wheels may fall out when starting or driving, and when the forklift is driven down the road, press the counterweight return switch (not shown) provided in the driver's seat to reverse the operation of the counterweight. The counterweight 4 is returned to the state in which the forklift truck is closely attached to the rear of the forklift truck, and the forklift truck is balanced so that the safe driving can be performed, and the counterweight 4 is mounted on the guide paths 3 and 3A. It is connected to the support sliding on the left and right side, so that there is no worry that the counterweight will be detached during operation. There is no need to store auxiliary counterweight separately, so there is no hassle when storing it.
