Abstract
Description
본 발명은 철도 레일 받침대에 관한 것으로서, 더욱 상세하게는 폐타이어 분말을 금형 내부에 고압으로 분사하여 철도 레일용 받침대를 제작함으로써, 기차의 하중을 충분히 견디면서 진동 소음을 감소시키고 또한 폐타이어의 자원 재활용에 기여할 수 있는 철도 레일 받침대에 관한 것이다.The present invention relates to a rail rail support, and more particularly, by injecting waste tire powder into a mold at a high pressure to produce a rail rail support, thereby reducing vibration noise while sufficiently bearing the load of the train and further reducing resources of the waste tire. A railroad rail support that can contribute to recycling.
일반적으로 철도 레일의 받침대로 사용되는 침목은 나무로 제작된 것임으로콜타르(오일)를 도포하여 내수성을 갖도록 하였다. 그러나 오래 사용하다 보면 방수성이 떨어지기 때문에 정기적으로 콜타르를 칠해야 되는 번거로움이 있으며, 나무에 수명이 있기 때문에 오래된 침목을 교체해야 됨으로 경제적으로 유지관리비용이 많이 드는 단점이 있었다.Generally, sleepers used as pedestals of railway rails are made of wood, so that coal tar (oil) is applied to have water resistance. However, long-term use has the disadvantage of having to apply coal tar on a regular basis because of poor waterproofing, and because of the life of the tree, the old sleepers have to be replaced, resulting in economical maintenance costs.
그리고 침목 대용으로 개발된 콘크리트 받침대의 경우 진동,충격에 약하기 때문에 균열이 발생될 수 있으며 진동,충격으로 인하여 레일과 연결된 핀이 빠질 우려가 있는 단점이 있다. 또한 지하철 등에 설치된 콘크리트 받침대의 경우 그 충격이 지하 시설물에 그대로 전달되기 때문에 지하시설물에 설치된 장치 등의 수명이 단축되는 등의 단점이 있었다.In addition, the concrete pedestal developed as a substitute for sleepers may have cracks because they are weak in vibration and impact, and the pins connected to the rail may fall out due to vibration and impact. In addition, in the case of the concrete pedestal installed in the subway, the impact is transmitted as it is to the underground facilities, such as shortening the life of the device installed in the underground facilities, etc. had a disadvantage.
이러한 문제점을 개선하기 위해 진동 충격에 강한 폐타이어를 철도 레일 받침대로 개발한 발명들이 제안된 바 있다. 이들 받침대는 폐타이어를 재활용하는 것임으로 자원 재활용성이 향상되고 또한 기차의 주행 중 발생되는 충격을 완화시켜 줄 수 있는 것이다.In order to improve this problem, inventions have been proposed in which waste tires resistant to vibration shocks are developed as rail rail supports. These pedestals are used to recycle waste tires, thereby improving resource recyclability and mitigating shocks generated by the train.
그러나 폐타이어를 분말로 만든 뒤 이 분말을 접착제와 함께 받침대로 성형한 것임으로 내구성이 떨어지는 단점이 있었다. 그리고 폐타이어 조각을 적층한 받침대가 제안된 바 있으나 이는 단순히 적층한 상태에서 볼트 등으로 체결한 것임으로 제품의 신뢰성이 떨어지는 등의 단점이 있었다.However, since the waste tire was made into a powder and then formed into a pedestal together with the adhesive, there was a disadvantage in that the durability was poor. In addition, a pedestal of stacking waste tire pieces has been proposed, but this is simply fastened with bolts in a stacked state, such that the reliability of the product is inferior.
본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 레일받침편을 갖는 기판 형강을 금형 내부에 넣고 폐타이어분말을 고압으로 분사시켜받침대가 만들어지도록 함으로써, 받침대를 쉽게 제작할 수 있으며 특히 기판이 내장되어 있음으로 내구성이 뛰어나면서 완충성이 좋은 철도 레일 받침대를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to insert a substrate-shaped steel having a rail support piece into a mold and spray the waste tire powder at a high pressure so that the support can be easily manufactured, In particular, the board is embedded to provide a rail rail support for excellent durability and cushioning.

상기 목적을 달성하기 위하여 본 발명은 "ㄷ"형강 또는 사각파이프 형강으로 구성된 기판이 구비되고, 기판의 표면에는 레일이 놓이는 한쌍의 레일고정편이 구비되며, 레일고정편을 제외하고 기판을 감싸도록 상,하부금형 내부에서 폐타이어분말이 고압으로 분사된 폐타이어분말층이 구비되도록 구성되어 있다.In order to achieve the above object, the present invention is provided with a substrate consisting of "c" section steel or square pipe section steel, the surface of the substrate is provided with a pair of rail fixing piece on which the rail is placed, so as to surround the substrate except the rail fixing piece It is configured to have a waste tire powder layer in which the waste tire powder is injected at a high pressure inside the lower mold.
이하 본 발명의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명 받침대 제조과정을 단계별로 나타낸 공정도이고, 도 2는 본 발명 받침대의 정단면도 이다. 본 발명은 "ㄷ"자 형강으로 구성된 기판(1)이 구비된다. 기판(1)은 표면에 레일(6)이 놓이는 한쌍의 레일고정편(2)이 용접 등의 수단으로 고정된다. 기판(1)은 기차의 하중을 받쳐주는 역할을 한다.1 is a process diagram showing the step of manufacturing the present invention step by step, Figure 2 is a front sectional view of the present invention pedestal. The present invention is provided with a substrate 1 composed of "c" shaped steel. As for the board | substrate 1, the pair of rail fixing pieces 2 which the rail 6 puts on the surface are fixed by means, such as welding. The substrate 1 serves to support the load of the train.
기판(1)을 하부금형(3)에 뒤집어 넣고 상부금형(4)으로 닫은 뒤 폐타이어분말을 800 ∼ 1500psi 압력으로 10 ∼ 15분간 분사 성형하여 폐타이어분말층(5)이 형성되도록 한다.The substrate 1 is turned over to the lower mold 3 and closed with the upper mold 4, and then the waste tire powder is spray molded at 800 to 1500 psi for 10 to 15 minutes to form the waste tire powder layer 5.
폐타이어분말층(5)을 구성하는 폐타이어분말은 자원재생공사에서 보급되는 입자 0.5 ∼ 2mm정도의 것이며, 폐타이어분말 73 ∼ 93중량%, 라텍스바인더 5 ∼ 20중량%, 가황제 2 ∼ 7중량% 등이 혼합된 것이다.The waste tire powder constituting the waste tire powder layer 5 has a particle size of 0.5 to 2 mm and is used in regeneration of resources. The waste tire powder is 73 to 93 weight%, latex binder 5 to 20 weight%, and vulcanizing agent 2 to 7 Wt% and the like are mixed.
폐타이어분말이 성형된 기판(1)을 상,하부금형(4)(3)에서 꺼내면 레일 받침대가 완성된다. 이 폐타이어분말층(5)은 기판(1)이 외부로 노출되지 않도록 보호해 주는 역할과 함께 완충되도록 해주는 역할을 한다.The rail base is completed by taking out the board | substrate 1 in which the waste tire powder was formed from the upper and lower molds 4 and 3. The waste tire powder layer 5 serves to protect the substrate 1 from being exposed to the outside and to buffer the substrate 1.
이처럼 제조되는 본 발명의 받침대는 형강으로 구성된 기판(1)의 외주면을 폐타이어분말층(5)이 감싸고 있기 때문에 기판(1)이 부식되거나 노후되지 않는다. 그리고 철도 레일(6)을 받쳐준 상태에서 기차가 지나가더라도 그 충격이 완화됨으로 소음을 감소시킬 수 있으며 폐타이어가 분말되 되어 있음으로 원하는 형태로 성형하기 편리한 것이다.The pedestal of the present invention manufactured as described above does not corrode or age the substrate 1 because the waste tire powder layer 5 surrounds the outer circumferential surface of the substrate 1 made of the shaped steel. And even if the train passes in the state supporting the rail rail (6) can reduce the noise by the shock is alleviated and is convenient to mold to the desired shape because the waste tire is powdered.
도 4는 본 발명 다른 실시예를 나타낸 것으로서 기판(1)이 사각형 파이프의 형태로 구성된 것이다. 사각형 기판(1)의 저면에 다수개의 구멍을 뚫어 금형 내부에서 성형할 때 폐타이어분말이 기판(1) 내부로 쉽게 충진되도록 해야된다. 이렇게 해주면 기판이 폐타이어분말에 완전히 감싸져 내구성이 향상된다.4 shows another embodiment of the present invention, wherein the substrate 1 is configured in the form of a rectangular pipe. When forming a plurality of holes in the bottom surface of the rectangular substrate (1) to form inside the mold, the waste tire powder should be easily filled into the substrate (1). In this way, the substrate is completely wrapped in the waste tire powder, thereby improving durability.
이상에서와 같이 본 발명에 따르면 폐타이어분말로 기판을 감싸기 때문에 원하는 형태로 제작하기 편리하며, 특히 받침대가 설치된 교량의 경우 충격이 교량으로 직접 전달되지 않음으로 진동에 따른 피로파괴가 누적되지 않음으로 교량의 수명이 연장되고 폐타이어를 재활용할 수 있음으로 자원재활용성이 향상되는 등의 효과가 있다.As described above, according to the present invention, since the substrate is wrapped in the waste tire powder, it is convenient to manufacture in a desired form. In particular, in the case of a bridge in which the pedestal is installed, since the impact is not directly transmitted to the bridge, fatigue failure due to vibration does not accumulate. The life span of the bridge can be extended and waste tires can be recycled, thereby improving resource recycling.
