Description

전차선용 활차 보조 연결장치{Sub connecting brackets for trolley wire tension control pulley}Sub-connecting brackets for trolley wire tension control pulley}

본 고안은 전기를 동력원으로 하는 전기 철도의 차량에 전원을 공급하기 위해 조가선과 함께 설치되는 전차선의 장력을 조절하는 장력조절 장치를 전주인 H빔에 연결시키도록 하는 전차선용 활차 보조 연결 장치에 관한 것이다.The present invention relates to a pulley auxiliary connection device for a catenary for connecting a tension control device for adjusting the tension of a catenary installed with a jog to an H-beam, the electric pole, to supply power to a vehicle of an electric railway using electricity as a power source. will be.

일반적으로 전기를 그 동력원으로 하는 열차에 전기를 공급하기 위하여 전차선이 설치되게 되고, 상기 전차선은 조가선에 매달리는 상태로 설치되는 한편 일정길이 단위로 나뉘어 그 양단이 선로변에 일정거리를 두고 가설되는 전주에 설치된 장력 조절장치에 연결되어 열차상부에 설치된 팬타그라프(pantagraph)와 전차선의 접촉이 양호하게 이루어지도록 항상 팽팽한 장력상태를 유지하도록 하고 있다.In general, a tram line is installed to supply electricity to a train using electricity as a power source, and the tram line is installed in a state in which a tram line is suspended, while the electric line is divided by a certain length unit, and both ends are hypothesized at a distance from the side of the track. It is connected to the tension control device installed in the train to maintain a tight tension at all times in order to make good contact with the pantagraph installed on the train.

이와 같이 전차선에 대한 장력상태를 일정하게 유지하기 위해 도 1및 도 2에 도시된 바와 같이 조가선(2)에 매달린 전차선(1)이 당겨지는 양단에 설치되는 장력조절 장치는 온도변화에 의한 전차선(1) 및 조가선(2)의 장력을 자동으로 일정하게 유지하도록 하기 위하여 활차비 1 : 4의 활차(5)에 장력추(7)를 연결하고 상기 활차(5)에 설치된 소활차(4)에 전차선(1)과 조가선(2)을 일괄한 와이어로프(3)를 연 결하여 온도변화에 따라 장력추(7)가 상하로 승하강 되며 장력을 조절하게 되는 것으로, 상기 장력조절 장치는 일정거리를 두고 설치되는 H빔(10)으로 이루어지는 전주에 설치되어 전차선(1)을 일정장력으로 유지시키게 된다.As described above, in order to maintain a constant tension state with respect to the tram line, as shown in FIGS. 1 and 2, the tension control device installed at both ends of the tram line 1 which is suspended on the jaw line 2 is pulled out. 1) and the tension weight 7 is connected to the pulley 5 of the pulley ratio 1: 4 so as to automatically maintain the constant tension of the jaw wire (2) and to the small pulley (4) installed in the pulley (5) By connecting the wire rope (3) in which the tram line (1) and the barbed wire (2) are collectively connected, the tension weight (7) is moved up and down according to the temperature change, and the tension is adjusted to adjust the tension. It is installed on the pole consisting of the H beam 10 is installed to maintain the chariot line (1) at a constant tension.

상기 된 장력조절 장치가 원형의 콘크리트 전주에 설치되는 경우 원형밴드를 이용하여 전주에 고정시키도록 함으로써 원형밴드의 설치 각도를 조절하여 장력조절 장치가 전차선이 당겨지는 방향으로 지향되게 설치할 수 있으나, 콘크리트 전주 대신에 강관주 또는 H형강주등이 사용되는 관계로, 기존의 코크리트 전주에 장력조절 장치를 설치하기 위한 지지금구를 강관주 또는 H형 강주에 사용하는 경우 전차선이 당겨지는 각도와는 무관하게 선로방향에 대해 나란한 수평 방향을 지향하도록 지주에 용접이나 볼트 체결방법에 의해 설치될 수밖에 없게 된다.When the tension control device is installed on a circular concrete pole, by adjusting the installation angle of the circular band by fixing to the pole by using a circular band, the tension control device can be installed to be directed in the direction in which the tank line is pulled, but concrete Since steel pipes or H-beams are used instead of poles, when the jigs for installing tension control devices are used in steel pipes or H-beams, they are not related to the angle at which the tank line is pulled. In order to direct the horizontal direction parallel to the direction of the track is to be installed by welding or bolt fastening method to the shore.

따라서 기존 장력조절 장치의 활차는 전차선을 당기는 각도에 따라 회전이 가능하나 추유도구(8)는 선로와 수평방향으로 설치되므로 활차(5)와 장력추(7)가 정확한 수직상태를 이루지 못할 뿐만 아니라 와이어(6)가 추유도구(8)에 접촉된 상태로 승하강 하게 되면서 마찰로 인해 와이어(6)가 단선될 우려가 있는 것이었다.Therefore, the pulley of the existing tension control device can be rotated according to the pulling angle of the tramline, but since the lubrication tool 8 is installed in the horizontal direction with the track, the pulley 5 and the tension weight 7 do not achieve the exact vertical state. As the wire 6 was raised and lowered in contact with the chucking tool 8, the wire 6 could be disconnected due to friction.

즉 사각기둥 형태로 되는 전주에 설치되는 전차선 장력조절 장치가 전차선이 당겨지는 각도와는 무관하게 선로와 수평 방향으로 밖에 설치될 수밖에 없는 문제를 해결하기 위한 것이, 국내 실용신안등록 20-0204502호로 등록받은 바와 같이 사각기둥 형태의 전주에 대해 장력조절 장치를 부착 고정하기 위한 지지금구로 하여금 전주에 대해 그 설치각도가 가변상태로 부착 고정되게 함으로써 와이어의 수명을 연장하는 한편 장력조절이 원활히 이루어지도록 하고 있다.In other words, to solve the problem that the electric line tension control device installed in the poles in the form of a square column has to be installed only in the line and horizontal direction irrespective of the angle at which the electric line is pulled, registered as a Korean Utility Model Registration No. 20-0204502. As received, the supporter for attaching and fixing the tension adjusting device to the pole-shaped pole has the variable installation angle to the pole and is fixed to extend the life of the wire and smoothly adjust the tension. have.

Since the bolt hole 151 is moved up and down, and also the horizontal rotation around the hinge bolt 141, the pulley 5 is moved in the horizontal direction or the vertical direction according to the traction direction and the degree of the tramline 1 When actively coping with the pulley (5) is able to hold.

따라서 전차선(1)의 장력을 조절하는 장력조절장치를 구성하는 활차(5)를 기존의 지지금구인 걸음구(60)에 걸어서 연결하는 동시에 보조 취부고리(150)를 이용하여 연결되게 함으로써 전차선(1)의 과도한 장력에도 견디기가 용이하고, 또한 전차선(1)의 견인 방향에 따라 상하 좌우 회동이 일어나면서 당김 방향에 일직선으로 이동하여 당길 수 있게 되어 지지금구 및 연결장치의 변형이나 손상을 제거하는 한편 전차선(1)의 장력을 원활히 조절할 수 있게 된다.Therefore, by connecting the pulley (5) constituting the tension control device for adjusting the tension of the tank line (1) to the foot opening (60), which is the existing support, and at the same time to be connected by using the auxiliary mounting ring (150) It is easy to endure the excessive tension of 1), and it is possible to move in a straight line in the pulling direction while pulling up and down and left and right according to the pulling direction of the tank line 1 to remove the deformation and damage of the supporting tool and the connecting device. On the other hand it is possible to smoothly adjust the tension of the tank line (1).
