객차차축 조립용 리프트 장치{LIFTING APPARATUS FOR ASSEMBLING THE AXLE OF ROLLING STOCK}Lift device for carriage axle assembly {LIFTING APPARATUS FOR ASSEMBLING THE AXLE OF ROLLING STOCK}

본 발명은 차축을 안전하게 받치고 상하, 좌우로 미세조정하면서 안전하고 신속하게 차축을 교환할 수 있는 객차차축 조립용 리프트 장치에 관한 것이다.The present invention relates to a lift device for passenger car axle assembly that can safely and quickly exchange axles while safely supporting the axles and finely adjusting them up and down, left and right.

일반적으로 철도, 지하철 등에서 운영되는 차량은 10량 또는 20량을 하나로 고정편성하여 운영되고 있으며 고속철도차량의 경우에는 300km/h의 속도로 운행되고 있다.In general, a vehicle operated by rail, subway, etc. is fixedly operated in a unit of 10 or 20 vehicles, and in the case of a high-speed railway vehicle is operating at a speed of 300km / h.

이러한 차량의 주행거리가 증가하게 되면 주행안전을 위해 주기적인 차축교환이 이루어지는데 객차차축 교환시는 고정된 차축교환장치로 길이가 388m인 차량을 이동시켜 교환대상 차축이 위치한 상태에서 차축을 차량에서 풀면 차축교환장치를 하강시켜 교환될 차축을 내려놓고, 다시 교환하는 차축을 올려놓은 후에 상승시킨 상태에서 차량에 고정시키는 작업을 반복하였다. When the mileage of these vehicles increases, periodic axle replacement is performed for driving safety.When changing axle axles, the fixed axle exchanger moves a 388m long vehicle to move the axle from the vehicle. When released, the axle exchanger was lowered and the axle to be replaced was put down, and the axle to be replaced was put up again.

이러한 종래의 고정된 차축교환장치는 차축을 교환할 때마나 차량을 차축교환장치의 위치로 이동시켜야 하고, 여러개의 차축을 교환할 경우에도 하나씩 이동 시켜 작업해야 하므로 이동하는데 작업 시간이 현저히 증가되는 문제가 있다.The conventional fixed axle changer has to move the vehicle to the position of the axle changer whenever the axle is replaced, and when the multiple axles are replaced, the work must be moved one by one, thereby significantly increasing the working time. There is.

또한, 새로운 차축을 차량에 고정시키는 경우에도 차축이 차량과 전후방향 또는 좌우방향으로 어긋나면 인력으로 위치를 맞추어 차축을 교환해야 하므로 작업이 힘들고 시간이 걸리는 문제가 있다. In addition, even when the new axle is fixed to the vehicle, if the axle is displaced in the front-rear direction or the left-right direction with the vehicle, the axle needs to be replaced by maneuvering, so that the work is difficult and time-consuming.

먼저, 객차의 차축을 교환하기 위하여 레일에서 객차의 교환대상 차축을 분리한 상태에서 객차를 들어올리고 새롭게 장착되는 차축을 레일위에 올려놓는다.First, in order to exchange the axles of the carriages, the passengers are lifted and the newly mounted axles are mounted on the rails with the axles to be exchanged of the carriages separated from the rails.

차축 조립용 리프트의 하부지지대(10)에 형성된 이송손잡이를 이용하여 몸체 를 레일사이로 이송시키고, 새롭게 장착되는 차축의 하부에 차축지지대(60)를 위치시킨다. 그리고, 하부지지대(10)가 움직이지 않도록 몸체의 측면하부에 위치하는 고정대(13)를 지면에 밀착시켜 고정시킨다.The body is transferred between the rails using a transfer handle formed on the lower support 10 of the axle assembly lift, and the axle support 60 is positioned under the newly mounted axle. In addition, the lower support 10 is fixed to the ground by placing the fixing stand 13 located in the lower side of the body in close contact with the ground.

그 후, 조작스위치(14)를 이용하여 차축이 차축지지대에 위치하도록 수직이송부(30)를 상부방향으로 이송시키고, 계속 상승시켜 객차의 장착위치로 이송시켜 장착한다. Thereafter, by using the operation switch 14, the vertical transfer portion 30 is transferred upward so that the axle is positioned on the axle support, and is continuously raised to be transported and mounted to the mounting position of the passenger car.

이때, 차축이 객차의 장착위치에서 앞 또는 뒤에 위치하는 경우에는 전후이송레버(53)를 이용하여 받침대(40)를 전 또는 후방향으로 이동시켜 차축을 객차의 장착위치에 일치시킨 후에 장착한다. At this time, when the axle is located at the front or rear of the mounting position of the carriage, the front and rear transfer levers 53 are used to move the pedestal 40 in the forward or rearward direction so that the axle is aligned with the mounting position of the carriage.

또한, 차축이 객차의 장착위치에 위치하지만 좌측 또는 우측으로 어긋난 경우에는 좌우이송레버(56)를 이용하여 받침대(40)를 좌측 또는 우측으로 어긋난 길이만큼 이동시켜 차축을 객차의 장착위치에 일치시키고 장착한다.In addition, when the axle is located at the mounting position of the passenger car, but shifted to the left or right side, the left and right transfer levers 56 are used to move the pedestal 40 by the left or right shifted length to match the axle to the mounting position of the passenger car. Mount it.

이러한 과정을 거치면서 객차를 들어올린 상태에서 교체되는 차축을 레일에 올려놓은 상태로 다수의 차축을 안전하고 신속하게 교체할 수 있다.Through this process, a plurality of axles can be safely and quickly replaced with the axles being replaced on the rails while the passengers are lifted.
