It is about.

일반적으로, 철도의 레일은 열간 압연기를 통해 제작하게 되는 바, 압연기를 통해 길게 레일을 제작한 후 이를 일정 길이로 절단함과 아울러 레일의 표면을 검사한 후 이상이 없는 제품을 사용하게 된다.In general, the rail of the rail is produced through a hot rolling mill, after making a long rail through a rolling mill and cutting it to a certain length, and then inspects the surface of the rail to use a product without abnormalities.

즉, 압연기에서 제작된 레일을 사용하여 철로를 형성하기 위해서는 레일의 직진도가 매우 중요하고, 레일의 외관에 흠집이나 파손된 부분이 없어야 하기 때문에, 다수의 작업자가 육안으로 이를 검사하게 된다.That is, the straightness of the rail is very important in order to form the railway using the rail manufactured in the rolling mill, and since there should be no scratches or damages on the exterior of the rail, many workers visually inspect it.

여기서, 상기한 레일의 길이는 대략 20-25m 내외로 절단하여 사용하게 되는 바, 상기한 레일 한개의 중량은 대략 1500㎏ 내외가 됨으로써, 작업자가 이를 검사하기 위해서는 별도의 금속봉등으로 레일을 지렛대처럼 들어올리면서 레일의 4면을 검사하게 된다.In this case, the length of the rail is cut to about 20-25m and used, the weight of one of the rail is about 1500kg, so that the operator to check this by using a separate metal rod, such as a lever As you lift, you will inspect the four sides of the rail.

즉, 다수의 작업자가 금속봉을 지렛대로 해서 레일의 일측에서 레일을 들어 올리게 되면, 들려진 부분을 검사한 후 다시 반대쪽으로 이동하여 레일을 반대쪽으로 들어 올리면서 반대쪽을 검사하게 되는 것이다.In other words, when a number of workers lift a rail from one side of the rail by levering a metal rod, the inspected part is examined and then moved back to the opposite side to lift the rail to the opposite side to inspect the opposite side.

그러나, 상기한 바와 같이 여러명의 작업자가 1500Kg이 넘고 길이가 20m 이상인 레일을 지렛대로 뒤집으면서 육안 검사를 하게 되면, 하루에 많은 수의 레일을 검사하기 때문에 작업자의 근골격계(어깨, 허리, 무릅등)에 과다한 하중이 인가되어 작업자의 부상이 빈번하게 발생되는 문제점이 있다.However, as described above, when a number of workers visually inspect a rail having a length of more than 1500Kg and a length of 20m or more, by inverting a lever, the musculoskeletal system (shoulder, waist, knee, etc.) of the worker is inspected because a large number of rails are inspected per day. Excessive load is applied to the problem that the injury of the operator frequently occurs.

또한, 중량물인 레일을 뒤집기 때문에 소음이 크게 발생됨과 아울러 여러명의 작업자가 작업을 해도 신속한 육안 검사를 하기가 어려워 작업효율이 저하되는 문제점이 있다.In addition, since the heavy rail is reversed, noise is greatly generated, and even if several workers work, it is difficult to perform a quick visual inspection, thereby reducing work efficiency.
