Abstract
Description
본 발명은 전차선로 시공 및 유지보수, 검사, 진단 업무에 투입하는 장비에관한 것으로, 더욱 상세하게는 전차선로 시공 및 유지보수, 검사, 진단 업무를 하는데 있어서 정확한 데이터 값을 얻음과 동시에 여러 항목을 측정 할 수 있으며, Bluetooth를 이용해 레이저와 태블릿 PC간 공유가 가능해 태블릿 PC에서 터치 방식으로 레이저를 측정하면 데이터 값이 태블릿에 엑셀 파일로 저장되므로 정확한 데이터 값을 얻을 수 있으며 보고서 작성시 오류를 줄일 수 있을뿐만 아니라 현장에서는 전기철도 특성상 야간 작업이 많아 작업시간이 한정 되기 때문에 시공이나 유지보수, 검사, 진단 업무시 정확한 측정뿐만 아니라 속도면에서도 향상시켜주는 전차선 Pre_Sag 측정 및 가동브래킷 회전변위 측정기에 관한 것이다.The present invention relates to equipment used in tram line construction, maintenance, inspection, and diagnosis work. More specifically, it relates to equipment used in tram line construction, maintenance, inspection, and diagnosis work to obtain accurate data values and to measure various items at the same time. It can be measured and shared between the laser and a tablet PC using Bluetooth, so if you measure the laser with a touch method on the tablet PC, the data values are saved as an Excel file on the tablet, so you can get accurate data values and reduce errors when writing reports. In addition, due to the nature of electric railways, there is a lot of night work at the site, so work hours are limited, so it is about catenary Pre_Sag measurement and movable bracket rotational displacement measuring instrument that improves not only accurate measurement but also speed during construction, maintenance, inspection, and diagnostic work. .
전동차는 팬터그래프를 전차선에 접촉시켜 25,000V (교류구간), 1500V(직류구간)의 전기를 받아 기차 운행에 필요한 동력용 전원을 공급한다. 전동차에 필요한 전기를 정확히 공급하려면 전차선에는 일정한 높이, 균등한 장력, 적은 요동 등이 필요한데 가장 중요한 사항은 전차선이 팬터그래프에서 항상 일정한 거리와 높이 내에 있어야 한다는 것이다. The electric train receives electricity of 25,000V (AC section) and 1,500V (DC section) by contacting the pantograph to the tram line to supply the power needed to run the train. In order to accurately supply the electricity needed for electric trains, the tram line needs a constant height, equal tension, and little fluctuation. The most important thing is that the tram line must always be within a certain distance and height from the pantograph.
전차선의 위치가 레일중심에서 어느 정도를 유지하고 있는가를 전차선 편위라 하며, 레일에서 전차선 까지의 거리를 전차선 높이라 하는데, 이는 선로조건·온도변화 등에 따라 변화되기 때문에 주기적으로 측정·점검하고 일정거리가 벗어나면 보수를 하여 전동차의 운행에 지장이 없도록 하여야 한다. 전철 초창기에는 보수자가 전 구간을 순회하며 편위자를 사용하여 수작업으로 검측을 하고, 측정 후 필요한 개소에 대하여 보수작업을 시행하였다. 그러나 보수자가 수작업으로 검측을 함으로써 측정 시에 오차가 발생되어 효과적인 보수에 애로가 발생하였는데 그 오차는 주로 검측자에 따른 오차, 편위자 흔들림에 의한 오차, 움직이는 차량과의 조건에서 발생하는 오차 등이다.The degree to which the position of the tram line is maintained from the center of the rail is called the tram line deviation, and the distance from the rail to the tram line is called the tram line height. This varies depending on track conditions, temperature changes, etc., so it is periodically measured and inspected and a certain distance is maintained. If it is out of order, it must be repaired to prevent any disruption to the operation of the train. In the early days of the subway, maintenance workers toured the entire section, inspected manually using a deflector, and performed repair work on necessary areas after measurement. However, as the maintenance person performed the measurement manually, errors occurred during measurement, causing difficulties in effective maintenance. The errors were mainly errors due to the operator, errors due to the shake of the deflector, and errors arising from conditions with moving vehicles. .
전철에 전력을 공급하는 전차선의 편위 및 높이는 전철 운행의 안전에 관련된 주요 측정 항목이다.The excursion and height of the tram line that supplies power to the subway are key measurement items related to the safety of subway operation.
전차선의 높이는 전차선과 팬터그래프의 안정적인 접촉을 위하여 균일한 높이를 유지해야 하며, 전차선은 팬터그래프 접촉면(shoe)의 균일한 마모를 위하여 지그재그(zigzag) 로 설치되어야 한다. 편위의 방향은 50m 간격으로 설치된 전주(electronic pole)에 따라 좌우로 바뀌며, 편위량은 좌우 ±200mm 이내 이어야 한다. The height of the tram line must be maintained at a uniform height for stable contact between the tram line and the pantograph, and the tram line must be installed in a zigzag pattern to ensure uniform wear of the pantograph contact surface (shoe). The direction of deviation changes left and right according to electronic poles installed at 50m intervals, and the amount of deviation must be within ±200mm left and right.
도면을 참고하면 좌측과 우측에 가동브래킷 회전변위를 측정하기 위해 레이저를 각각 배치했고, 가운데 높이 및 편위를 측정하기 위해 레이저를 배치했다. 또, 좌, 우측에 태블릿 PC를 거치해서 1대는 높이, 편위를 측정할 때 Bluetooth를 이용해 태블릿에서 터치 방식으로 측정하면 높이 값은 데이터가 태블릿에 자동으로 저장되도록 했으며, 편위 값은 작업대 Rail을 기준으로 스티커를 부착해 육안으로 값을 읽을 수 있도록 했다. 그리고, 높이, 편위 값을 측정 후 예를들어 전철주가 우측에 있으면 우측 레이저를 이용해 전철주 중심을 측정해서 가동브래킷 회전변위를 측정하도록 했다. 이렇게 1개의 지지점을 측정하고 다음 지지점으로 이동시 전철주와 전철주간을 경간이라고 하는데 이 경간 사이의 전차선의 처짐 상태 즉 Pre_Sag를 측정해서 양쪽 지지점과의 높이차를 계산할 수 있다. 이처럼 이 장비는 레일 바퀴를 장착함으로써 이동이 편리하며 태블릿 및 레이저 위치도 사람이 섰을 때 측정하기 편한 높이를 구현하였다.Referring to the drawing, lasers were placed on the left and right sides to measure the rotational displacement of the movable bracket, and a laser was placed in the center to measure the height and deviation. In addition, a tablet PC is mounted on the left and right sides to measure height and deviation. When measuring the height and deviation using a touch method on the tablet, the height value is automatically saved to the tablet. The deviation value is based on the workbench rail. A sticker was attached so that the value could be read with the naked eye. Then, after measuring the height and deviation values, for example, if the subway pole is on the right, the center of the pole was measured using the right laser to measure the rotational displacement of the movable bracket. When measuring one support point like this and moving to the next support point, the subway pole and the subway main are called spans. By measuring the sagging state of the tram line between these spans, that is, Pre_Sag, the height difference between both support points can be calculated. As such, this equipment is easy to move by being equipped with rail wheels, and the tablet and laser positions are positioned at a height that makes it easy to measure when a person is standing.
기존에 측정하는 방식은 가선측정기라고 사람이 인력으로 측정기를 운반하며 지지점에서 측정자 손잡이를 들어올려 전차선에 접촉해서 높이와 편위를 측정하는 방식으로 측정하는 사람마다 오차가 클 수 밖에 없었다. 그 후 개발 된 것이 간이 레이저 측정 방식인데 레일에 "ㄷ"자 방식으로 거치해서 레이저를 사람이 쪼그려 앉아 수동으로 측정하는 방식으로 불편한 자세와 한번 측정하면 측정기를 들고 이동 하는 방식이었다. 이와 같은 종래 기술에 따른 전차선 높이, 편위 측정기는 이동이 불편하고 정확한 데이터 값을 구현하기 힘든 단점이 있으며, 또 높이, 편위만을 측정하던 측정기였다. The existing measuring method was called a overhead line measuring machine, where a person carried the measuring instrument by hand, lifted the measuring handle from a support point, and contacted the tram line to measure the height and deviation. Errors were bound to be large for each person measuring. What was later developed was a simple laser measurement method, which was mounted on a rail in an "ㄷ" shape and had a person squat down to measure the laser manually. This was an awkward position and, once measured, the user had to carry the measuring device and move it around. The catenary height and deflection measuring device according to the prior art has the disadvantage of being inconvenient to move and difficult to obtain accurate data values, and it was a measuring device that only measured height and deflection.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 이동이 편리하고 정확한 데이터 값을 확보하여야 하며, 레이저와 태블릿간에 공유를 통해 자동으로 데이터 값이 저장되며 높이, 편위뿐만 아니라 가동브래킷 회전변위를 동시에 측정할 수 있도록 하였으며 Pre_Sag를 측정해 양쪽 지지점간에 높이차를 계산하여 전차선의 기울기를 알 수 있도록 하였다. 또, 이동이 편리하도록 레일 바퀴를 장착해 진단 및 검사량을 늘릴 수 있도록 하였다.The present invention is intended to solve the above problems. It is convenient to move and secure accurate data values. The data values are automatically saved through sharing between the laser and the tablet, and the height and deviation as well as the rotational displacement of the movable bracket are simultaneously measured. By measuring Pre_Sag, the height difference between both support points was calculated to determine the slope of the tram line. In addition, rail wheels were installed for convenient movement, allowing for increased diagnosis and inspection volume.
상기의 목적을 달성하기 위한 기술적 사상으로서의 본 발명은 본체를 형성하는 작업대를 가볍게 하도록 프로파일 자재를 30*30으로 제작하여야 하며, 가운데 레이저와 우측 태블릿을 Bluetooth를 이용해 연동 시켰으며, 좌, 우측 레이저를 좌측 태블릿과 연동 시켰다. 또, 이동이 편리하도록 레일바퀴 장착을 시도했으며, 손잡이는 이동시 편리하게 각도조절(180도)이 되도록 하였고 보관시에는 접히도록 설계 하였다.The present invention, as a technical idea to achieve the above object, requires that the profile material be manufactured to 30*30 to lighten the workbench forming the main body, and the center laser and right tablet are linked using Bluetooth, and the left and right lasers are connected to each other using Bluetooth. It was linked to the tablet on the left. In addition, an attempt was made to install rail wheels for convenient movement, and the handle was designed to be angle-adjustable (180 degrees) for convenient movement and folded for storage.
본 발명에 따른 전차선 Pre_Sag 측정 및 가동브래킷 회전변위 측정기에 의하면, 반자동화된 기계구성으로 인하여 전차선 높이, 편위 및 기울기, 가동브래킷 회전변위를 측정할 수 있어 한번 이동으로 여러가지 항목을 측정할 수 있으며, 정확한 데이터 값을 레이저와 태블릿간에 연동을 통해 보다 쉽게 활용할 수 있고 검사 효율은 극대화하면서 안전한 열차 운행에 도움을 줄 수 있는 이점이 있다.According to the catenary Pre_Sag measurement and movable bracket rotational displacement measuring device according to the present invention, due to the semi-automated machine configuration, it is possible to measure the catenary height, deviation and inclination, and movable bracket rotational displacement, so that various items can be measured with one movement, There is an advantage in that accurate data values can be utilized more easily through linking between the laser and tablet, and can help in safe train operation while maximizing inspection efficiency.
이하, 본 발명의 바람직한 실시예를 첨부도면에 의거하여 상세하게 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.
높이, 편위 측정기는 일반적으로 사람이 수동으로 측정하는 방식에서 현재 "ㄷ"자 모양으로 제작된 거치대에서 쪼그려 앉아 레이저를 이용해 측정해 수기로 적는 방식이다.Height and deviation measuring instruments are generally measured manually by people, but are now squatting on a stand made in the shape of a "ㄷ" and measuring using a laser and writing them down by hand.
본 발명은 상기와 같은 측정 방식에서 벗어나 "프로파일"이라는 알루미늄 자재를 이용해 하부 프레임을 제작하였으며 그 하부프레임에 레일바퀴를 장착해 이동이 편리하도록 하였다. The present invention deviates from the above-mentioned measurement method and manufactures a lower frame using an aluminum material called "profile" and attaches rail wheels to the lower frame for convenient movement.
사람이 서 있을때 편한 자세에서 측정이 가능하도록 골조를 세워 상부 작업대와 연결하도록 하였으며 이동시 편리하도록 손잡이를 회전방식으로 설치해 작업시에는 본인이 편한 자세에서 측정하도록 각도 조절이 가능하도록 하였으며 평상시 보관시에는 손잡이가 접히는 방식을 구현 하였다.To enable measurement in a comfortable position when a person is standing, the frame was erected and connected to the upper workbench. The handle was installed in a rotating manner for convenient movement, so that the angle could be adjusted to measure in a comfortable position when working, and the handle was used for normal storage. A folding method was implemented.
측정시 레이저 이동이 편리하도록 상부 작업대에 Rail를 설치했으며, 편위 값을 측정하기 위해 편위 줄자(스티커)를 제작해 붙이도록 하였다.A rail was installed on the upper workbench to facilitate movement of the laser during measurement, and a deviation tape measure (sticker) was made and attached to measure the deviation value.
측정 레이저는 총 3대를 설치해 가운데 레이저는 높이, 편위, Pre_Sag를 측정하도록 하였으며, 좌 우측 각각 1대는 전철주 위치에 따라 사용해 가동브래킷 회전변위를 측정하도록 설계되었다.A total of three measurement lasers were installed, with the middle laser measuring height, deviation, and Pre_Sag, and one each on the left and right sides, designed to measure the rotational displacement of the movable bracket according to the position of the subway pole.
또, 정확한 데이터 값을 얻기 위해 수기로 작성하는 기존 시스템에서 벗어나 가운데 레이저와 우측 태블릿 PC간에 Bluetooth를 이용해 태블릿에서 터치 방식으로 측정하면 가운데 레이저가 측정해 그 데이터 값이 자동으로 태블릿에 저장되는 방식으로 설계되었다. 그리고, 가운데 레이저로 높이, 편위를 측정함과 동시에 좌, 우측에 레이저를 활용해 전철주 중심을 찍으면 처음 측정한 높이, 편위 위치에서 가동브래킷이 온도에 따라 얼마나 회전 했는지를 알 수 있도록 하였다.In addition, in order to obtain accurate data values, in a departure from the existing system of manually writing down data, if you measure by touch on the tablet using Bluetooth between the center laser and the right tablet PC, the center laser measures and the data values are automatically saved to the tablet. It was designed. In addition, by measuring the height and deviation with the center laser and at the same time using lasers on the left and right sides to take a picture of the center of the subway pole, it was possible to know how much the movable bracket rotated depending on the temperature at the first measured height and deviation position.
현재 한국철도공사, 또는 시공사에서 사용하는 방식은 "ㄷ"자 모양으로 제작된 거치대에 레이저를 설치해서 측정해 수기로 작성하는 방식을 사용하고 있는데 본 발명으로 수요가 바뀔 수 있다고 판단됨.Currently, the method used by the Korea Railroad Corporation or construction companies is to install a laser on a stand made in the shape of "ㄷ" and measure the measurements and write them down by hand. It is believed that demand may change with this invention.
