본 고안은 포오크 리프트(Fork Lift)에 부착되는 포오크에 관한 것으로 유압에 의해 랙과 피니언이 작동 되어 포오크가 회전할 수 있도록한 포오크 리프트의 회전 포오크에 관한 것이다.The present invention relates to a fork attached to a fork lift, and relates to a fork lift that rotates a fork lift by operating a rack and pinion by hydraulic pressure.

일반적으로, 포오크 리프트에 사용되는 통상의 포오크는 ＂L＂자형으로 굽혀져 수직 부분과 수평부분으로 구성되어 있으며 수직 부분에 부착되어 있는 후크에 의하여 포오크가 캐리지(Carriage)에 고정되고 캐리지는 유압 시스템에 의하여 상.하로 움직일 수 있게 되어 있으므로 사용시에는 캐리지에 고정된 포오크의 수평부분에 물체를 실어 울리게 되어 있어 단지 들어올리는 기능만을 가지고 있었으나 포오크를 회전시켜 쏟아 부어야하는 화물 및 기울여야 하는 화물을 취급할수 있는 포오크 리프트가 요구되어 종래에는 유압모터의 회전이 웜과 웜기어, 피니언, 링기어의 순서로 구동되어 회전판을 회전시켜서 포오크를 회전시켰으나 유압모터는 개발과정에 어려움이 많고 보편화 되지 않아서 단가가 높으며, 회전 저항을 줄이기 위한 수단으로 많은 베어링을 사용하므로서 구조가 복잡하고 고장율이 많은 단점이 있었다.Generally, forks used for forklifts are bent in a “L” shape, consisting of vertical and horizontal parts, and the forks are fixed to the carriage by the hooks attached to the vertical parts, and the carriage is hydraulic system. It is able to move up and down by using it, so when using it, the object is loaded on the horizontal part of the fork fixed to the carriage, and it only has the function of lifting, but it can handle the cargo to be poured and the cargo to tilt by rotating the fork. Fork lift is required, and in the past, the rotation of the hydraulic motor is driven in the order of worm, worm gear, pinion, and ring gear to rotate the fork by rotating the rotary plate. However, the hydraulic motor is difficult to develop and is not universalized. As a means to reduce resistance Hameuroseo complex structures using a steering failure rate and there was a lot of disadvantages.

따라서 본 고안은 종래의 단점을 해소하고 물체를 들어 올림과 동시에 포오크가 회전하여 쏟아 부어야 하는 화물 및 일반 팔레트(Pallet)작업도 할 수 있는 회전 포오크를 제공 하려는데 그 목적이 있다.Therefore, the present invention aims to solve the disadvantages of the prior art and to provide a rotating fork that can also carry out cargo and general pallet work in which the forks rotate and pour at the same time.

본 고안을 첨부한 도면에 의거하여 상세하게 설명하면 다음과 같다.Referring to the present invention in detail based on the accompanying drawings as follows.

제2도 내지 제3도에 도시한 바와 같이 유압 실리더(1)의 피스톤축(2) 단부에 랙 A(3)가 고정되고, 반대방향으로 또 다른 유압 실린더(1')의 피스톤축(2')단부에 B(3')가 고정되어 있으며, 랙A(3)와 랙B(3') 사이에 케리지(7)에 연결된 피니언(5)이 물려 서로 반대 방향으로 직선운동하는 랙A, B(3)(3')의 힘을 받아 회전운동하도록 되어 있으며 랙A, B(3)(3')의 안내와 스톱퍼 역할을 하는 로울러 베어링(4)(4')이 설치되어져 있다.As shown in FIGS. 2 to 3, the rack A 3 is fixed to the end of the piston shaft 2 of the hydraulic cylinder 1, and the piston shaft of another hydraulic cylinder 1 'in the opposite direction ( 2 ') B (3') is fixed at the end, and rack A (3 ') between rack A (3) and rack B (3') pinion (5) connected to carriage (7) is engaged and linearly moves in opposite directions The roller bearings are rotated under the force of B (3) (3 '), and roller bearings (4) (4') are installed to guide and stop the racks A and B (3) (3 ').

미설명부호 6은 포오크 8은 조작레버 이러한 구성의 본 고안은 포오크의 회전 조작레버(8)를 조작하면 유압회로가 형성되어 양 실린더(1)(1')의 피스톤축(2)(2')이 랙A, B(3)(3')를 밀거나 당기게 되어 랙A, B(3)(3')는 서로 반대방향으로 직선운동을 하게 되며 이 직선운동을 피니언(5)이 회전으로 바꾸어 캐리지(7)를 회전시키므로서 포오크(6)가 회전되어 쏟아부어야 하는 화물 및 기울여야 하는 화물을 취급할 수 있도록 한 것이다.Reference numeral 6 denotes a fork 8 and an operating lever. In this configuration, the hydraulic circuit is formed when the rotary operating lever 8 of the fork is operated so that the piston shafts 2 and 2 'of both cylinders 1 and 1' are formed. ) Pushes or pulls racks A and B (3) (3 ') so that racks A and B (3) (3') make linear movements in opposite directions. By changing the carriage (7) by rotating the fork (6) is to be able to handle the cargo to be poured and cargo to be tilted.

또한 로울러 베어링(4)(4')은 랙A, B(3)(3')의 안내와 스톱퍼 역할을 한다.The roller bearings 4 and 4 'also serve as guides and stoppers for the racks A and B (3) and 3'.

이상과 같이 본 고안은 랙과 피니언의 특성을 이용하므로서 구조가 간단하며 동작이 용이하고 캐리지와 포오크가 같이 회전하여 쏟아 부어야 하는 화물을 취급할수 있어 포오크에 용기를 장착하여 유용성 있는 물체(액체)등의 취급이 가능하고 일반 팔레트 작업에도 사용할 수 있는 실용적인 고안인 것이다.As described above, the present invention utilizes the characteristics of the rack and pinion so that the structure is simple and easy to operate, and the carriage and the fork rotate together to handle the cargo to be poured. It is a practical design that can be handled and used for general pallet work.
