Abstract

The method for inserting the stern tube bush bearing to support the shaft for transmitting the main engine power in shipbuilding, is composed of inserting the shaft (2) to the stern tube (1); inserting the stern-side bush (3) and the bow-side bush (4) to both ends of the shaft (2); fixing the stern/bow bush pads (3a)(4a) to the bush and clamping them by nuts (B)(B'). The center-hole hydraulic jack (J) is mounted between the stern bush pad (3a) and nut (B).

본 발명은 선박건조시 메인 엔지의 출력을 전달하는 샤프트를 지지하며 회전을 원활하게 하기 위하여 베어링, 즉 선미튜브 부쉬를 삽입하는 방법에 관한 것이다.The present invention relates to a method for inserting a bearing, that is, a stern tube bush to support a shaft that transmits the output of the main engine during ship construction and to facilitate rotation.

종래의 선미튜브부위 삽입방법은 제2도와 같은 우선 선미쪽 튜브부쉬(3)와 선수쪽 튜브부쉬(도시없음)가 있는데 선미쪽 튜브부쉬(3)를 샤프트(2)에 삽입시키고 지그 즉 부쉬패드(14)와 너트(15)로 지지시키고 선수쪽에서 4대의 유압잭(16)(16')이 설치된 잭패드(17)를 샤프트(2)에 끼워 너트(15')로 고정시키고 1세트의 유압 분배면(6가닥)을 이용하여 작업 및 검사를 종료후 선수쪽 튜브부쉬를 같은 방법으로 지그를 교체하여 작업 및 검사를 실시하여야 하기 때문에 지그를 2세트 준비하거나 크레인을 이용하여 선미쪽 선외에서 선수쪽 선내로 이동교체하여 작업 및 검사를 6시간에 걸쳐 8명의 인원으로 선미, 선수쪽에서 선주선급입회 검사를 2회 하여야 하는 번거로움과 지그 교체로 인한 안전사고의 문제점이 있었다.Conventionally, the stern tube inserting method includes a first stern tube bush (3) and a bow tube bush (not shown) as shown in FIG. 2. The stern tube bush (3) is inserted into the shaft (2) and a jig or bush pad is inserted. (14) and nut (15) and jack pads (17) provided with four hydraulic jacks (16) and (16 ') on the bow side. After finishing work and inspection by using 6 strands, the bow tube bushing should be replaced by the same method and the work and inspection should be carried out. There was a problem of safety accidents due to the hassle and the jig replacement that the ships should be inspected twice at the stern and forehands by eight persons over 6 hours.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 선미튜브부쉬의 삽입을 선미, 선수쪽을 분활하지 않고 동시에 양방향에서 2개의 선미 튜브부쉬를 1개의 유압잭과 펌프를 이용하여 동시에 삽입할 수 있게 하였으며, 검사 또한 1회로 종료할 수 있고 지그 역시 선내, 외 이동없이 1세트로 작업가능케 하였다.In order to solve the above problems, the present invention allows two stern tube bushes to be inserted simultaneously using one hydraulic jack and a pump in both directions without splitting the stern tube bush into the stern and bow side. The inspection can also be completed once, and the jig can be operated in one set without moving on and off the ship.

이하 발명의 요지를 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 선미튜브(1) 내부로 길이조정 및 취급이 용이하게 2개로 하여 중앙에서 나사로 연결한 샤프트(2)를 끼우고 샤프트(2)의 양단에 선미튜브부쉬(3)와 선수튜브부쉬(4)를 삽입시키며 그 후단에 선미부쉬패드(3a), 선수부쉬패드(4a)로 밀착시켜 너트(B)(B')로 조이되 선미부쉬패드(3a)와 너트(B)사이에는 센터를 유압잭(J)을 설치하여 센터홀 유압잭(J)을 작동시키면 양단에 지지되어 있던 튜브부쉬(3)(4)가 샤프트(2)의 안쪽으로 밀려 정위치로 들어오게 되면, 선주선급검사도 1회로써 삽입 작업을 종료하게 된다.According to the present invention, the length of the stern tube 1 can be easily adjusted and handled so that the shaft 2 is screwed in the center and the stern tube bush 3 and the bow tube bush are formed at both ends of the shaft 2. 4) Insert and tighten the stern bush pad (3a) and bow bush pad (4a) at the rear end and tighten with nut (B) (B '), and center the stern bush pad (3a) between the nut (B). When the hydraulic jack (J) is installed and the center hole hydraulic jack (J) is operated, the tube bushes (3) and (4) supported at both ends are pushed into the shaft (2) to enter the home position. The insert operation is terminated.

이와 같은 본 발명은 4대 유압잭을 1대로 줄이고 펌프와 1세트의 유압 분배변 호스를 없애고 펌프자체로 실시하며 2세트의 지그를 1세트로 8명이 6시간에서 4명에 1시간으로, 선주선급검사도 2회에 1회에 실시 가능하여 그에 다른 자재비와 공수, 인원절감을 꾀할 수 있는 효과가 있는 것이다.In the present invention, the four hydraulic jacks are reduced to one, the pump and one set of hydraulic distribution valve hoses are removed, and the pump itself is carried out. The two sets of jig are one set of eight people from six hours to four people for one hour. Inspection can also be carried out once every two times, which is effective in reducing other materials costs, man-hours, and personnel.
