Problems solved by technology

[0003] Since the wheel changing process requires the train to stop and brake, the overall size of the bogie results in a complex process, long replacement time and low efficiency
Therefore, a device and method for changing wheelsets during online train operation has been developed. However, during the online train replacement process, the wheelsets need to be disassembled from the train, and between the first track and the second track of different gauges There is a certain distance, and the train has neither wheels nor rails during this distance, so it cannot run online. There is an urgent need for a support structure that can support the train to run online without affecting the train's replacement of wheel sets.

Embodiment 1

[0093] Embodiment 1 provides a method for changing wheels, which is suitable for changing the wheels of a train between the first track and the second track of different gauges. The first track is suitable for the first wheel pair, and the second track is suitable for the second track. Two wheel pairs, with a distance between the first track and the second track, figure 1 A process diagram of a wheel changing method provided in an embodiment of the present invention, combined with figure 1 , the method includes:

[0094] S1, the traction train travels from the first track to the second track;

[0095] S2. During the process of the train traveling from the first track to the second track, supporting the train so that the train remains suspended during the distance between the first track and the second track;

[0096] S3, dismantling the first wheel pair on the suspended train;

[0097] S4, installing the second wheel pair on the train from which the first wheel pair was rem...

Embodiment 2

[0101] Embodiment 2 provides a wheel changing device suitable for the wheel changing method in Embodiment 1.

[0102] figure 2 It is a structural schematic diagram of a wheel changing device in this embodiment, combined with figure 2 , the device includes a traction unit 100 , a supporting device 200 , a removal unit 300 and an installation unit 400 .

[0103] Specifically, the traction unit 100 is used to pull the train from the first track 500 to the second track 600; The distance between the first track 500 and the second track 600 remains suspended during the walking process; the dismantling unit 300 is used to dismantle the first wheel pair on the suspended train; the installation unit 400 is used to install the second wheel pair to dismantle the first wheel pair on the train.

[0104] The above wheel changing device may further include a bogie 800 , a storage unit 900 and a detection unit 1000 .

Embodiment 3

[0106] Embodiment 3 provides a traction unit, which can be used in the wheel changing method in Embodiment 1 and is suitable for the wheel changing device in Embodiment 2.

[0107] Figure 4 for figure 2 Schematic diagram of the overall structure of the traction unit in , combined with Figure 4 , in this embodiment, the traction unit 100 may include a tractor 110, the tractor 110 may include a car body 111 and a traction arm 112, the car body 111 walks synchronously on one side of the train, and one end of the traction arm 112 is connected to the car body 111 , the other end of the traction arm 112 is operatively connected to or detached from a connecting coupler for connecting two adjacent carriages of the train. The tractor 110 walks and can drive the traction arm 112 to walk, and the traction arm 112 is connected with the connecting couplers of the two adjacent compartments of the train. Therefore, the tractor 110 can push the train to walk from the first track 500 to t...

Abstract

The invention discloses a supporting device which is used for supporting a train in the process that the train travels from a first track to a second track for wheel changing so that the train can be kept suspended in the distance traveling process between the first track and the second track. Wherein the two transverse sides of a bogie of the train are correspondingly supported by one first supporting part, each first supporting part comprises a supporting vehicle and a lifting assembly, each lifting assembly is arranged on the corresponding supporting vehicle, each supporting vehicle operably and synchronously walks with the train, and each lifting assembly is provided with a telescopic end capable of stretching upwards back and forth; the telescopic end of the lifting assembly operably supports the train to suspend the train. The supporting device provided by the device can support the train, so that the distance between the first track and the second track of the train is kept suspended, the train can still run even if no wheel set or track exists, and the purposes of short time and high efficiency of on-line wheel set replacement of the train are achieved.

Description

technical field [0001] The invention belongs to the technical field of rail changing and wheel changing for railway wagons, and in particular relates to a supporting device. Background technique [0002] Railway track change and wheel change are the main means for trains to adapt to different gauges. When changing wheels, after the train is braked and stopped at a fixed location, the lifting equipment is used to lift the train, and the bogie and the wheel set on the train are lifted. Whole replacement, to achieve the purpose of train track change. [0003] Since the wheel changing process needs to stop and brake the train, the overall bogie is relatively large, resulting in complicated process, long changing time and low efficiency. Therefore, a device and method for changing wheelsets during online train operation has been developed. However, during the online train replacement process, the wheelsets need to be disassembled from the train, and between the first track and t...
