본 고안은 포크 리프트(Fork Lift)의 포크구조에 관한 것으로, 좀더 구체적으로는 포크의 저면부에 완충장치를 설치하여 적재물의 하역시 또는 체인절단등의 돌발사고시 포크와 적재물의 손상을 방지할 수 있게 한 것이다.The present invention relates to a fork structure of a fork lift, and more specifically, a shock absorbing device is installed at the bottom of the fork to prevent damage to the fork and the load during an accident such as unloading the load or cutting a chain. It was made.

포크리프트에는 적재물을 얹기위한 한쌍의자형 포크가 설치되어 있으며, 이포크는 브라켓에 고정되고 브라켓은 다시 체인에 연결되어 체인의 구동에 따라 포크는 승, 하강 운동을 하게 된다.The forklift has a pair of loads The fork is installed, the fork is fixed to the bracket and the bracket is connected to the chain again so that the fork moves up and down as the chain is driven.

그러나 종래에 일반적으로 사용되어온 포크는 단지 적재물을 얹을 수 있는 형상으로만 되어있을뿐 포크가 지면에 닿을 때 포크에 가해지는 충격을 완충시키는 장치가 없기 때문에 적재물의 적재시나 하역시 포크가 지면에 닿으면서 약간씩의 충격을 받게되고, 특히 적재물을 상승시키거나 하강시키는 도중 체인이 절단되는 등의 돌발사고가 발생하여 포크가 적재물과 함께 자유낙하하는 경우 포크가 지면에 충돌하면서 받는 충격으로 인해 포크가 절단, 파손됨은 물론 적재물도 심하게 파손될 우려가 있다.However, conventionally used forks have only a shape that can load the load, and there is no device to buffer the impact of the fork when the fork touches the ground. If the fork falls freely along with the load, in case of sudden accident such as the chain is cut while raising or lowering the load, the fork collides with the ground. Not only cutting and breaking, but also the load may be severely damaged.

본 고안은 지면과 접촉하는 포크의 저면부위에 탄력성이 있는 완충부재를 설치하여 포크가 지면과 충돌할 때 포크에 가해지는 충격을 감소시킬 수 있도록 한 것인바, 본 고안의 바람직한 실시예를 첨부도면과 관련하여 상세하게 설명하면 다음과 같다.The present invention is to install a resilient buffer member on the bottom portion of the fork in contact with the ground to reduce the impact on the fork when the fork collides with the ground bar, according to a preferred embodiment of the present invention In detail with respect to the following.

첨부도면 제1도와 제2도는 본 고안의 일실시예를 나타낸 사시도로서, 포크(1)의 저면부에 소정크기와 홈(2)이 형성되어있고 이 홈(2)에 탄력성이 우수한 완충고무(3)가 끼워진 상태로 육각구멍붙이 볼트(4)와 왓사(5)로 고정되어 있다.1 and 2 are perspective views showing an embodiment of the present invention, in which a predetermined size and a groove 2 are formed at the bottom of the fork 1, and the rubber 2 has excellent elasticity. 3) is secured by the hexagon socket head bolt 4 and the washer (5).

또한 완충고무(3)의 전방에는 경사면(3a)이 형성되어 완충고무의 마모를 최대한 방지할 수 있게 된다.In addition, the inclined surface (3a) is formed in front of the buffer rubber (3) can be prevented to the maximum wear of the buffer rubber.

이 실시예에서는 포크(1)가 지면에 충돌할 때 포크(1)의 저면부가 직접 지면에 닿지않고 완충고무(3)가 먼저 지면에 닿게되므로 체인절단등의 돌발사고로 포크(1)가 자유낙하하는 경우에도 완충고무(3)에 의해 포크(1)에 전달되는 충격이 최대한으로 감소되어 포크의 절단이나 파손은 물론 포크위에 얹혀진 적재물의 파손을 방지해 주고 불의의 안전사고로부터 인명을 보호할 수 있게 된다.In this embodiment, when the fork 1 collides with the ground, the bottom portion of the fork 1 does not directly touch the ground, and the cushioning rubber 3 first touches the ground, so the fork 1 is freed by an accident such as chain cutting. Even in the case of a drop, the shock transmitted to the fork 1 by the cushioning rubber 3 is reduced to the maximum, thereby preventing the fork from being cut or damaged, as well as damaging the load on the fork, and protecting human life from accidental safety accidents. It becomes possible.

제3도는 본 고안의 다른 실시예를 나타낸 단면도로서, 이 실시예에서는 포크(1)의 저면부위에 형성된 홈(2)에 탄성 및 강성이 우수한 겹판스프링(6)이 결합되어 있으며 겹판스프링(6)의 하단은 포크의 저면보다 하방으로 돌출되어 있다.3 is a cross-sectional view showing another embodiment of the present invention. In this embodiment, a leaf spring 6 having excellent elasticity and rigidity is coupled to a groove 2 formed at the bottom of the fork 1, and the leaf spring 6 The bottom of the) protrudes below the bottom of the fork.

따라서 포크(1)가 자유낙하하는 경우 겹판스프링(6)이 포크(1)에 전달되는 충격을 최대한으로 감소시킬 수 있게 된다.Therefore, when the fork 1 falls freely, the leaf spring 6 can reduce the shock transmitted to the fork 1 to the maximum.

제4도는 본 고안의 또다른 실시예를 나타낸 단면도로서, 포크(1)의 저면부위에 형성된 홈(2)에 수개의 스프링(7)이 설치되어 있고 스프링의 하단에는 받침판(8)이 고정되어 있으며 각 스프링의 상단에는 서포트(9)가 결합되어 있고 서포트(9)는 핀(10)에 의해 포크(1)와 연결되어 있다.4 is a cross-sectional view showing another embodiment of the present invention, in which a plurality of springs 7 are installed in the grooves 2 formed in the bottom portion of the fork 1, and the support plate 8 is fixed to the bottom of the springs. A support 9 is coupled to the upper end of each spring, and the support 9 is connected to the fork 1 by a pin 10.

이 실시예에서도 포크(1)가 낙하하는 경우 받침판(8)이 먼저 지면에 접촉하면서 스프링(7)이 압축되고 스프링의 압축에 의해 포크(1)에 전달되는 충격이 감소되므로 포크와 적재물의 파손은 물론 안전사고의 위험을 예방할 수 있게 된다.Even in this embodiment, when the fork 1 falls, the support plate 8 first contacts the ground, and thus the spring 7 is compressed and the shock transmitted to the fork 1 by the compression of the spring is reduced, so that the fork and the load are broken. In addition, the risk of safety accidents can be prevented.
