Description

철도차량 집전장치의 설치구조{mounting structure of railway vehicle current collector}Mounting structure of railway vehicle current collector

본 발명은 철도차량용 집전장치의 설치구조에 관한 것으로, 더욱 상세하게는 대차프레임보다 상대적으로 상하운동 변위가 작은 액슬박스에 브래킷을 통해 집전장치를 설치하여 집진 성능을 종래보다 향상시킬 수 있는 철도차량 집전장치의 설치구조에 관한 것이다.The present invention relates to an installation structure of a current collector for a railway vehicle, and more particularly, a railway vehicle capable of improving dust collection performance by installing a current collector through a bracket on an axle box having a smaller vertical displacement than a bogie frame. An installation structure of the current collector.

일반적으로 철도차량은 철도의 선로 위를 운행할 목적으로 제조한 차량으로서, 내연기관이나 전기기관을 동력으로 하여 운행하는 철도차량과 자기(磁氣)의 힘에 의해 운행하는 철도차량으로 나누어지며, 전기기관으로 운행되는 철도차량은 중전철과 경전철로 구분된다.In general, a railroad car is a vehicle manufactured for the purpose of running on railroad tracks, and is divided into a railroad car driven by an internal combustion engine or an electric engine and a railroad car driven by a magnetic force. Railway vehicles operated by electric engines are classified into heavy and light rail.

그리고 경전철을 이루는 철도차량은 승객이나 화물을 싣는 차체와, 상기 차체의 하부에 설치되어 차체의 중량을 부담하고 차체에 대해 자유롭게 방향을 전환하여 차량의 주행을 원활하게 하는 대차와, 상기 레일에 인접하여 설치되어 외부의 전력이 공급되는 가선에 접촉하여 철도차량에 전력을 공급하는 집전장치로 이루어진다.In addition, the railroad vehicle forming the light rail is a vehicle that carries passengers or cargo, and a bore that is installed under the vehicle to bear the weight of the vehicle and freely change its direction with respect to the vehicle, and the rail is adjacent to the rail. It is installed by the contact is made of a current collector for supplying power to the railroad car in contact with the external power line.

또, 상기 대차(100)는 도 1에 도시된 바와 같이 차축(310)의 양단부에 각각 액슬박스(200)가 설치되고, 상기 액슬박스(200)의 중앙에는 바퀴(300)의 차축(310)이 회전가능하게 고정되고, 상기 대차프레임(110) 및 액슬박스(200) 사이에는 완충기(400)가 각각 설치된다.In addition, as shown in FIG. 1, the axle box 200 is installed at both ends of the axle 310, and the axle 310 of the wheel 300 is disposed at the center of the axle box 200. The rotatable fixing is performed, and a buffer 400 is installed between the bogie frame 110 and the axle box 200, respectively.

그러므로 주행중인 철도차량(10)에 레일(20)의 상태 및 기타요인에 의해 진동 및 충격이 발생하게 되면, 상기 완충기(400)는 대차(100)를 포함하여 상부에 설치된 차체(11)를 상하운동하게 하여 진동 및 충격을 완화하였다.Therefore, when vibrations and shocks occur due to the state of the rail 20 and other factors in the traveling railway vehicle 10, the shock absorber 400 includes the bogie 100 up and down the vehicle body 11 installed on the upper portion. The movement was relieved of vibration and shock.

종래의 철도차량 집전장치의 설치구조는 도 1, 2에 도시된 바와 같이 차체(11)의 하부 일측에 집전장치(500)가 설치되는 구조로서, 이 집전장치(500)는 가선(30)으로부터 전력을 공급받아 그 전력을 철도차량(10)에 전달하고, 철도차량(10)은 전력을 동력으로 변환하여 차축(310)에 전달하면, 바퀴(300)는 차축(310)을 중심으로 회전하게 되므로, 철도차량(10)은 바퀴(300)를 통해 레일(20)을 따라 주행하게 된다.The conventional structure for installing a railway vehicle current collector is a structure in which a current collector 500 is installed at a lower side of the vehicle body 11 as shown in FIGS. 1 and 2, and the current collector 500 is connected to the wire 30. When the electric power is supplied and transmitted to the railway vehicle 10, and the railway vehicle 10 converts the power into power and transmits the power to the axle 310, the wheel 300 rotates about the axle 310. Therefore, the railroad vehicle 10 travels along the rail 20 through the wheel 300.

그러나 종래의 철도차량 집전장치의 설치구조는 집전장치가 차체의 하부 일측에 설치되어 있음으로, 철도차량 주행시 집전장치도 차체와 함께 상하운동하게 되어 집전장치는 큰 변위에 의해 노후화가 가속화되면서 집전 성능이 저하되는 문제점이 있었다.However, in the installation structure of the conventional railway vehicle current collector, since the current collector is installed on one side of the lower part of the vehicle body, the current collector also moves up and down with the vehicle body when the railroad vehicle runs, and the current collector accelerates aging due to large displacement, and the current collector performance is improved. There was a problem of this deterioration.

그리고 집전장치의 집전 성능이 저하를 방지하기 위해 집전장치를 차체보다 상대적으로 상하운동 변위가 작은 대차프레임에 설치하려고 하였지만, 경전철을 이루는 철도차량의 대차프레임은 하부공간이 협소하여 집전장치를 설치하는 것이 불가능하였다.In order to prevent the current collector's current collection performance from deteriorating, the current collector was intended to be installed in a bogie frame with a smaller displacement than the vehicle body, but the bogie frame of a railroad car, which is a light rail, has a low space to install a current collector. It was impossible.

이에 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 철도차량에 설치되는 집전장치를 상하운동 변위가 적은 부위에 설치함으로써, 집전장치의 노후화를 방지하면서 집전 성능도 저하되지 않도록 하는 것을 제공하는 것이다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to install the current collector installed on the railway vehicle in a portion of the vertical displacement small displacement, while preventing the aging of the current collector, the current collector performance is also not degraded.

이상과 같이 구성된 본 고안의 작용 상태를 설명하면 다음과 같다.Referring to the working state of the present invention configured as described above are as follows.

도 3, 4에 도시된 바와 같이 철도차량(10)이 집전장치(500)를 통해 가선(30)으로부터 전력을 공급받아 그 전력을 동력으로 변환하여 차축(310)에 전달하면 바퀴(300)는 액슬박스(200)에 회전가능하게 고정된 차축(310)을 중심으로 회전하게 되어 철도차량(10)은 바퀴(300)를 통해 레일(20)을 따라 주행하게 된다.As shown in FIGS. 3 and 4, when the railroad vehicle 10 receives electric power from the cable line 30 through the current collector 500, converts the electric power into power, and transmits the electric power to the axle 310, the wheel 300 is provided. The railroad vehicle 10 is driven along the rail 20 through the wheels 300 by rotating about the axle 310 rotatably fixed to the axle box 200.

그리고 주행중인 철도차량(10)에는 레일(20)의 상태 및 기타요인에 의해 진동 및 충격이 발생하게 되어 대차(100)를 포함하여 대차(100)의 상부에 설치된 차체(11)는 진동 및 충격에 의해 상하운동을 하게 되고, 대차프레임(110) 및 액슬박스(200) 사이에 설치된 완충기(400)는 이러한 진동 및 충격을 완화하지만, 대차(100)의 상부에 설치된 차체(11)는 진동 및 충격에 의해 출렁거리면서 상하운동하게 된다.In addition, the railroad vehicle 10 that is running generates vibrations and shocks due to the state of the rails 20 and other factors, and the vehicle body 11 installed on the upper portion of the vehicle 100 including the vehicle 100 vibrates and impacts. Up and down by the movement, the shock absorber 400 is installed between the bogie frame 110 and the axle box 200 to mitigate such vibrations and shocks, but the vehicle body 11 installed on the top of the bogie 100 vibrates and It will move up and down due to the impact.

이때, 집전장치(500)는 차체(11) 및 대차프레임(110)보다 상대적으로 상하운동 변위가 작은 액슬박스(200)에 브래킷(600)을 통해 설치됨으로써, 종래 가선(30)과 집전장치(500)의 이격으로 집전장치(500)의 집전 성능이 저하되는 것이 방지된다.At this time, the current collector 500 is installed through the bracket 600 to the axle box 200 having a smaller vertical displacement than the vehicle body 11 and the bogie frame 110, the conventional wire 30 and the current collector ( The separation of the current collector 500 prevents the current collector performance of the current collector 500 from being lowered.

이를 구체적으로 설명하면, 액슬박스(200)는 중앙에 바퀴(300)가 차축(310)에 의해 회전가능하게 고정되어 있으며, 상기 바퀴(300)는 항상 레일(20)을 따라 주행하기 때문에, 대차프레임(110)에 설치된 액슬박스(200)는 진동 및 충격에 의해 상하운동 변위가 거의 발생하지 않는다.Specifically, the axle box 200 is fixed to the wheel 300 in the center rotatably by the axle 310, because the wheel 300 always runs along the rail 20, bogie The axle box 200 installed in the frame 110 hardly generates vertical movement displacement due to vibration and shock.

또, 도 5, 6에 도시된 바와 같이 액슬박스(200)의 고정부(211) 및 브래킷(600)의 일단부(600a)는 상기 고정부(211)의 요홈(212)에 상기 브래킷(600)의 요철(610)이 끼워져 고정되고, 제1 체결부재(B1)가 상기 요홈(212) 및 요철(610)에 체결되었기 때문에, 상기 요홈(212) 및 요철(610)은 상기 액슬박스(200)의 고정부(211) 및 브래킷(600)의 일단부에 결합력을 증대시키고, 집전장치(500)의 하중이 직접 제1 체결부재(B1)에 전달되지 않도록 함으로써, 제1 체결부재(B1)는 굽힘 응력에 의해 휘거나 부러지는 것이 방지된다.5 and 6, the fixing part 211 of the axle box 200 and the one end 600a of the bracket 600 have the bracket 600 in the recess 212 of the fixing part 211. Since the concave-convex 610 of the) is fitted and fixed, and the first fastening member B1 is fastened to the concave-convex 212 and the concave-convex 610, the concave-convex 212 and the concave-convex 610 are the axle box 200. The first fastening member B1 by increasing the bonding force at one end of the fixing portion 211 and the bracket 600 and preventing the load of the current collector 500 from being directly transmitted to the first fastening member B1. Is prevented from bending or breaking by bending stress.

또한, 도 5, 7에 도시된 바와 같이 브래킷(600)의 타단부(600b)와 집전장치(500)의 베이스부(510)는 상기 브래킷(600)의 제1 래크부(611)와 상기 베이스부(510)의 제2 래크부(511)가 서로 맞물려 고정되고, 제2 체결부재(B2)가 상기 제2 래크부(511)에 형성된 장공(511a)을 관통하여 상기 제1 래크부(611)에 형성된 나사공(611a)에 체결되어 고정되었기 때문에, 상기 제1 래크부(611) 및 제2 래크부(511)는 브래킷(600)에 고정된 집전장치(500)가 상하로 이동하는 것을 방지하고, 바퀴(300)가 마모되어 브래킷(600)의 위치가 기존보다 내려갈 경우에는 상기 제1 래크부(611)에 맞물린 제2 래크부(511)를 올려 집전장치(500)와 가선 사이에 간극을 조절할 수가 있다. In addition, as shown in FIGS. 5 and 7, the other end 600b of the bracket 600 and the base part 510 of the current collector 500 may include the first rack part 611 and the base of the bracket 600. The second rack portion 511 of the portion 510 is engaged with each other and fixed, and the second fastening member B2 penetrates through the long hole 511a formed in the second rack portion 511 so that the first rack portion 611 is fixed. Since the first rack portion 611 and the second rack portion 511 are fastened and fixed to the screw hole 611a formed at the bottom surface of the bracket hole 611a, the current collector 500 fixed to the bracket 600 is moved up and down. If the wheel 300 is worn and the position of the bracket 600 is lowered than before, the second rack portion 511 engaged with the first rack portion 611 is raised to raise the gap between the current collector 500 and the wire. The gap can be adjusted.
