Abstract

PURPOSE: A marine shaft alignment method using a Total Station is provided to reduce time for aligning work and to improve accuracy by performing centering work with using Total Station. CONSTITUTION: Centering jigs(2) are installed at the ends of a stern boss block(1). A Total Station(10) is positioned at the position for installing the engine of a ship. The centering position of the centering jig is measured with using the Total Station. The centering position is measured until that the center of Total station and centering jig is on the same line is decided. The centerline of a power shaft is controlled with not naked eye but the Total Station and therefore, the time for aligning work is reduced and accuracy is improved. A piano wire(20), passed through the boss center(35) of a rudder horn(30) of the stern boss block, is used for measuring the center of the centering jig.

Description

토탈 스테이션을 이용한 선박 축타계 정렬 방법{Axis align method using total station}Axis align method using total station}

본 발명은 선박의 축타계 정렬 방법에 관한 것으로서, 특히 선박의 항행을 위한 동력을 발생시키는 스쿠류와 엔진을 연결하는 동력축의 중심선을 직선으로 정렬하는 작업을 수행함에 있어 토탈 스테이션을 이용하여 센터링 작업을 하여 정밀도를 향상시킬 수 있도록 한 선박 축타계 정렬 방법에 관한 것이다.The present invention relates to a method for aligning a gear system of a ship. In particular, the centering operation is performed by using a total station in performing a straight line alignment of a center line of a power shaft connecting a engine and a scoop that generates power for navigation of the ship. The present invention relates to a method for aligning a ship's gear system so that the precision can be improved.

도 1은 종래에 사용하고 있는 선박 축타계 정렬 방법을 나타내는 도면으로서, 선박의 스턴 보스 블록(1)의 양단에 센터링 지그(2)를 설치한다. 또한, 스턴보스 블록(1)에서 소정 거리만큼 이격된 곳에 광원(3)을 설치한다.FIG. 1 is a diagram illustrating a conventional method for aligning a ship's gear system, and a centering jig 2 is provided at both ends of the stern boss block 1 of the ship. In addition, the light source 3 is provided at a position spaced apart from the stern boss block 1 by a predetermined distance.

센터링 지그(2)가 설치된 후, 스턴 보스 블록(1)의 뒷부분에서 센터링 지그(2)를 직시하면 센터링 지그(2)는 동심원 형태로 보이게 된다. 센터링 지그(2)가 동심원 형태로 보일 때, 동심원의 중앙부에 광원(3)이 보이도록 광원(3)의 위치를 조정하여 고정시킨다.After the centering jig 2 is installed, when the centering jig 2 is directly faced at the rear of the stun boss block 1, the centering jig 2 appears to be concentric. When the centering jig 2 looks like a concentric circle, the position of the light source 3 is adjusted and fixed so that the light source 3 is visible at the center of the concentric circle.

광원(3)이 고정된 후, 스턴 보스 블록(1)과 광원(3) 사이에 동력축을 지지하기 위한 동력축 지지 지그(4)를 다수개 설치한다. 이때 지지 지그(4)가 설치될 때 광원(3)에서 발광된 빛이 가려지지 않도록 지지 지그(4)와 센터링 지그(2)가 서로 동심원이 이루어지도록 하면 동력을 전달하는 동력축이 설치되는 축타계가 정확히 정렬되게 된다.After the light source 3 is fixed, a plurality of power shaft support jigs 4 for supporting the power shaft are provided between the stun boss block 1 and the light source 3. At this time, if the support jig 4 and the centering jig 2 are concentric with each other so that the light emitted from the light source 3 is not obscured when the support jig 4 is installed, a shaft for installing a power shaft for transmitting power is installed. The manuscript is aligned correctly.

상기한 정렬 방법을 사용할 경우, 광원, 센터링 지그 및 지지 지그의 정렬을 작업자의 감각에 의존하기 때문에, 숙련자만이 할 수 있고, 작업자의 피로 상태에 따라 정렬 정밀도가 변화되는 문제점을 갖고 있다.When the above-described alignment method is used, since the alignment of the light source, the centering jig, and the supporting jig depends on the operator's sense, only a skilled person can perform the problem, and the alignment accuracy changes according to the worker's fatigue state.

본 발명은 상기한 문제점을 해결하기 위한 것으로서, 선박의 항행을 위해 동력을 스쿠류로 전달하는 동력축이 설치지지되는 지그를 일직선으로 정렬함에 있어 토탈 스테이션을 사용하여 센터링 지그의 중심을 설정하고 동력축이 지지되는 지지 지그를 토탈 스테이션에 의해 위치를 설정하도록 하는 토탈 스테이션을 이용한 선박 축타계 정렬 방법을 제공하는 것을 목적으로 한다.The present invention is to solve the above problems, in order to align the jig in which the power shaft for transmitting the power to the scoop for the navigation of the ship in a straight line to set the center of the centering jig using the total station and the power shaft It is an object of the present invention to provide a method for aligning a ship shaft system using a total station that allows this supported support jig to be positioned by a total station.

도면을 참조하여 본 발명을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the drawings.

도 2는 본 발명에 의한 선박 축타계 정렬 방법을 나타내는 도면으로서, 스턴 보스 블록(1)의 양단에 센터링 지그(2)를 설치하는 것은 종래의 기술과 동일하다. 이때 사용하는 센터링 지그(2)의 형태가 도 3에 도시되어 있다.FIG. 2 is a view showing a method for aligning a ship's gear system according to the present invention, in which the centering jig 2 is provided at both ends of the stun boss block 1 as in the prior art. The shape of the centering jig 2 used at this time is shown in FIG. 3.

도 3에 도시된 바와 같은 형태의 센터링 지그(2)는 센터링 지그(2)에 부착되어 있는 암(3)의 길이를 조정함으로서 각각 다른 크기의 스턴 보스 블록에 적용할 수 있다.The centering jig 2 of the type shown in FIG. 3 can be applied to stun boss blocks of different sizes by adjusting the length of the arm 3 attached to the centering jig 2.

스턴 보스 블록(1)의 양단에 센터링 지그(2)를 설치한 후, 선박의 엔진 설치 위치에 토탈 스테이션(10)을 위치시킨 후 센터링 지그(2)의 위치를 측정한다. 토탈 스테이션(10)을 이용한 센터링 지그(2)의 측정값에 의하여 토탈 스테이션(10)과 센터링 지그(2)의 중심이 동일선상에 있는 것으로 판명될 때까지 토탈 스테이션(10)을 이동시키면서 측정 작업을 계속한다.After the centering jig 2 is provided at both ends of the stun boss block 1, the total station 10 is positioned at the engine installation position of the ship, and then the position of the centering jig 2 is measured. Measurement operation while moving the total station 10 until the center of the total station 10 and the centering jig 2 is found to be in the same line by the measured value of the centering jig 2 using the total station 10. Continue.

이때 센터링 지그(2)의 중앙은 원형으로 형성되어 있어, 토탈 스테이션(10)을 이용한 측정 작업을 위한 타켓(target)이 없으므로, 타켓으로 사용하기 위해 피아노선을 설치하도록 한다.At this time, since the center of the centering jig (2) is formed in a circular shape, there is no target (target) for the measurement operation using the total station 10, so to install the piano wire for use as a target.

도 4는 피아노선의 설치 상태를 나타내는 도면이다.4 is a diagram illustrating an installation state of a piano wire.

우선 스턴 보스 블록(1)의 후부 데크 위치에 피아노선(20)을 수직으로 설치하도록 한다. 이때 피아노선의 선박 항행시 항행 방향을 결정하는 러더(미도시)의 회전중심을 구성하는 러더혼(30)의 보스 센터(35)를 통과시켜 설치하게 되면, 센터링 지그(2)의 중앙 부위에서 피아노선(20)이 보이게 되어, 토탈 스테이션(10)에서센터링 지그(2)의 중심 측정을 위한 기준으로 사용할 수 있게 된다.First, the piano wire 20 is installed vertically at the rear deck position of the stun boss block 1. At this time, when passing through the boss center 35 of the rudder horn 30 constituting the center of rotation of the rudder (not shown) to determine the direction of navigation when sailing the piano ship, the piano at the center of the centering jig (2) The line 20 is visible so that it can be used as a reference for the center measurement of the centering jig 2 at the total station 10.

피아노선(20)이 설치된 후, 러더혼(30)과 보스 센터(35)와의 교차점 간격을 측정하고, 러더혼(30)의 보스 센터(35)의 편심 정도와 데크) 높이를 측정한다.After the piano wire 20 is installed, the distance between the intersection points between the rudder horn 30 and the boss center 35 is measured, and the eccentricity and deck height of the boss center 35 of the rudder horn 30 are measured.

이후에 편심에 따른 러더혼 부쉬(미도시)를 가공하고, 가공된 부쉬를 러더혼(30)에 설치하도록 한다.After processing the horn horn bush (not shown) according to the eccentricity, and to install the processed bush in the rudder horn (30).

상기와 같은 본 발명에 의하면 선박의 항행을 위해 스크류와 엔진을 연결하는 동력축의 중심선이 스크류와 엔진의 중심축과 일치되도록 설치하는 작업을 함에 있어 동력축의 중심선을 작업자의 육안에 의한 조정이 아닌 토탈 스테이션을 사용한 조정작업을 하도록 하여 정렬 작업의 시간을 절약하고 정밀도를 높이는 효과를 갖는다.According to the present invention as described above, the center line of the power shaft connecting the screw and the engine for the navigation of the ship in the work to be installed so as to match the center axis of the screw and the engine in the center of the power shaft, not a total adjustment by the operator's naked eye By adjusting the station, it saves time and improves the accuracy.
