The present invention relates to an elastic pad for a track divider for increasing the main function and life of a fastening device.

일반적으로 철도레일 체결장치는 레일을 침목에 고정하기 위하여 레일의 분기기 등에 레일의 간격 조절 및 견고한 지지를 위하여 침목 상면에 설치된다.In general, railway rail fastening device is installed on the upper surface of the sleeper for adjusting the gap of the rail and the rigid support for fixing the rail to the sleeper.

여기서, 통상적인 종래의 철도레일 체결장치는 도 1에 도시된 바와 같이, 상면에 레일(2')이 안착되는 상판(10')과 팬드롤 클립(32')이 결합되고, 상기 상판(10') 상면에 상기 레일(2')이 안착되는 소정의 간격을 가지고 양측에 장착되는 클립지지대(31')로 구성된다.Here, in the conventional conventional railway rail fastening apparatus, as shown in Figure 1, the upper plate 10 'and the pedroll roll clip 32' is coupled to the upper plate 10 'on which the rail 2' is seated, the upper plate 10 ') Is composed of a clip support (31') mounted on both sides with a predetermined interval on which the rail (2 ') is seated on the upper surface.

즉, 도 2에 도시된 바와 같이, 침목(1') 상면에 설치되는 상판(10') 상면에 레일(2')을 안착시킨 후, 상기 클립 지지대(31')에 결합된 팬드롤 클립(32')에 의해 상기 레일(2')의 하부가 지지되어 철도의 분기기에 체결 고정되는 것이다.That is, as shown in Figure 2, after mounting the rail (2 ') on the upper surface of the upper plate 10' is installed on the upper surface of the sleeper (1 '), the pod roll clip coupled to the clip support (31') ( 32 '), the lower part of the rail 2' is supported and fastened to the branch of the railway.

상기한 바와 같은 구성으로 이루어진 종래의 철도레일 체결장치는 상기 상판(10') 및 클립지지대(31')가 철재 등과 같은 금속재로 일체로 형성되어 있으므로, 철도차량이 레일(2')을 주행하거나 정차할 경우에 발생되는 진동에 의한 충격이 레일(2')의 하부를 지지하여 고정하는 팬드롤 클립(32')이나 체결장치의 하부에 설치되는 침목(1')에 직접 전달되는 폐단이 있었다.In the conventional railway rail fastening device having the configuration as described above, since the upper plate 10 'and the clip support 31' are integrally formed of a metal material such as steel, the railway vehicle runs the rail 2 'or There was a closed end where the shock caused by the vibration generated when the vehicle was stopped is directly transmitted to the pad roll clip 32 'for supporting and fixing the lower part of the rail 2' or the sleeper 1 'installed at the lower part of the fastening device. .

즉, 레일을 통과하는 철도차량의 심한 진동 등에 따른 충격으로 인하여 팬드롤 클립(32')이 쉽게 파손되어 레일(2')의 체결력이 저하되고, 철도레일 체결장치를 지지하는 침목(1')은 오랜 기간 반복하여 사용할 경우 쉽게 파손되어 철도차량의 주행이나 정차중 발생되는 진동과 소음이 더욱 증대되는 문제점이 있었다.That is, the panda roll clip 32 'is easily damaged due to the impact caused by the severe vibration of the railroad car passing through the rail, and thus the fastening force of the rail 2' is lowered, and the sleeper 1 'supporting the railroad rail fastening device. When used repeatedly for a long time, there is a problem in that the vibration and noise generated during driving or stopping of the railway vehicle are further increased.

또한, 철도차량이 운행중 발생되는 진동은 철도차량의 차체에도 전달되어 차체의 주요기능부를 손상시키는 문제가 있었다.In addition, the vibration generated during the operation of the railway vehicle is also transmitted to the vehicle body of the railway vehicle, there is a problem that damages the main functional portion of the vehicle body.

따라서, 철도레일 체결장치와 침목의 유지 및 보수에 많은 경비가 소요되며, 철도차량 주행중 인명사고가 발생할 위험성이 있는 폐단이 있었다.Therefore, a lot of expenses are required for the maintenance and repair of railroad rail fastening devices and sleepers, and there was a danger that a human accident may occur while driving a railroad car.

이에, 상기한 바와 같은 제문제점을 해결하기 위해 등록실용신안 20-0235976호 방진용 철도레일 체결장치가 제안되었다.Accordingly, in order to solve the problems described above, the registration utility model 20-0235976 dustproof railway rail fastening device has been proposed.
