본 발명은 압연롤용 쵸크 자동 착탈장치의 이송부재에 관한 것으로, 더욱 상세하게는 압연롤의 양측에 조립된 쵸크의 착탈작업을 위해서 동작하는 디쵸킹부재를 원활하게 이송시켜 쵸크의 착탈효율을 극대화하기 위한 압연롤용 쵸크 자동 착탈장치의 이송부재에 관한 것이다.The present invention relates to a conveying member of the automatic choke detachable device for a rolling roll, and more particularly, to maximize the detachment efficiency of the choke by smoothly conveying the de-choking member operating for detaching work of the choke assembled on both sides of the rolling roll. It relates to a transfer member of the choke automatic detachment device for rolling rolls for.

일반적으로 압연롤은 제철산업에서 냉연 강판을 생산하기 위한 압연기(Mill)에 설치되어 강판(슬래브)의 이송속도와 압하율을 조절하여 다양한 규격을 갖는 냉연 강판을 생산하게 된다.In general, the rolling roll is installed in a mill for producing a cold rolled steel sheet in the steel industry to produce a cold rolled steel sheet having various specifications by controlling a feed rate and a rolling rate of the steel sheet (slab).

이러한 압연롤은 사용목적과 용도에 따라서 워크롤(Work roll), 백업롤(Back up roll) 등으로 구분되며 냉연 강판의 생산량 및 작업시간에 따라서 주기적으로 외경의 연마작업을 통해서 냉연 강판의 생산품질을 균일하게 유지하게 된다.These rolling rolls are divided into work rolls and back up rolls according to the purpose and purpose of use.The production quality of cold rolled steel sheet is periodically polished by the outer diameter according to the production and working time of the cold rolled steel sheet. To keep it uniform.

한편, 상기 압연롤(A)은 연마작업을 위해서 양측에 조립된 쵸크(B)를 분리한 후 Roll Shop으로 이송한 후 보수 및 연마작업을 진행하게 되는데, 이때 쵸크(B)의 효율적인 착탈작업을 위해서는 도 1에 도시된 바와 같이 지면에 설치된 레일을 따라서 좌우방향으로 이동하는 이송부재(10)와, 상기 이송부재(10)의 상부에 형성되어 전후방향으로 이동하면서 적치대(C)에 적치된 압연롤(A)의 쵸크(B)를 착탈하기 위한 디쵸킹부재(20)로 구성되는 압연롤용 쵸크 자동 착탈장치(1)를 사용하게 된다.On the other hand, the rolling roll (A) is to remove the choke (B) assembled on both sides for the polishing operation and then transfer to the Roll Shop to repair and polishing work, this time efficient removal of choke (B) In order to move in the left and right direction along the rail installed on the ground as shown in Figure 1, and the upper portion of the transfer member 10 formed in the upper and lower direction while being moved in the front and rear direction (C) The choke automatic attachment / detachment device 1 for a rolling roll comprised of the de-choking member 20 for attaching and detaching the choke B of the rolling roll A is used.

이때 상기 이송부재(10)는 하부에는 지면에 설치된 레일을 따라서 이동하기 위한 다수개의 주행바퀴(12)를 구비하고 상기 주행바퀴(12)의 일측에는 구동력을 발생하기 위한 구동모터(13)가 설치된 몸체(11)를 형성하되 상기 몸체(11)의 하부에는 상기 디쵸킹부재(20)를 전후방향으로 이송하기 위해서 설치된 유압실린더(30)로 구성된다.At this time, the transfer member 10 has a plurality of driving wheels 12 for moving along the rail installed on the ground at the bottom and the driving motor 13 for generating a driving force on one side of the driving wheel 12 is installed The body 11 is formed, but the lower part of the body 11 is composed of a hydraulic cylinder 30 installed to transfer the de-choking member 20 in the front-back direction.

따라서 상기 유압실린더(30)의 동작으로 상기 디쵸킹부재(20)가 전후방향으로 이동하면서 쵸크(B)의 착탈작업을 수행하게 된다.Therefore, the de-choking member 20 moves in the front-back direction by the operation of the hydraulic cylinder 30 to perform the detachment operation of the choke B.

그러나 상기 유압실린더(30)는 쵸크(B)의 착탈작업을 위해서 상기 디쵸킹부재(20)의 이송거리와 대응되는 행정거리를 갖게 되는데, 이는 행정거리가 길어질수록 작동과정에서 기계적인 무리 및 부하가 발생하게 되므로 결국 상기 유압실린더(30)의 내구성 저하 및 고장의 원인을 제공하는 단점을 갖게 되었다.However, the hydraulic cylinder 30 has a stroke distance corresponding to the transfer distance of the de-choking member 20 for the detachment operation of the choke (B), which is a mechanical force and load in the operation process as the stroke length increases Because of this will eventually have the disadvantage of providing a cause of durability degradation and failure of the hydraulic cylinder (30).

특히 중량물인 상기 디쵸킹부재(20)의 효율적인 이송을 위해서 규격(내경)이 상승한 대형의 유압실린더를 사용해야 하므로 경제적인 부담이 가중되는 폐단을 갖 게 되었다.In particular, in order to efficiently transport the de-choking member 20, which is a heavy object, a large hydraulic cylinder having an increased standard (inner diameter) has to be used, which has a closed end that increases the economic burden.

또한, 상기 유압실린더(30)의 행정거리가 길어질수록 발생하는 흔들림 및 진동으로 인해 상기 디쵸킹부재(20)의 원활한 이송이 어려워, 결과적으로 쵸크(B)의 정확하고 효율적인 탈착작업이 불가능하므로 작업범위가 극히 제한되는 문제점을 갖게 되었다.In addition, the smooth movement of the de-choking member 20 is difficult due to the shaking and vibration generated as the stroke length of the hydraulic cylinder 30 becomes longer, and as a result, the choke B cannot be accurately and efficiently removed and removed. The problem is that the scope is extremely limited.

따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서,Therefore, the present invention has been made to solve the above conventional problems,
