The operation car that this embodiment provided adopts vertical beam device 1, running gear 2, strutting arrangement 3 and lifting rail device 4, realizes functions such as short distance transportation, loading and unloading, sideslip, lift and rotation to the switch, has higher flexibility, has moreover that the transportation is convenient, the stand-alone handling ability is strong and the switch is spread and is traded accurate characteristics of counterpointing, aims at solving the construction pain point that the switch was spread and traded.
When the working vehicle runs, the rotary locking oil cylinder 29 is in a floating state, and the longitudinal beam 11 and the running gear 2 can freely rotate according to the steering requirement; when the support device 3 supports the working vehicle, the running gear 2 is in an idle state, the rotation locking oil cylinder 29 is locked, and random rotation between the running gear 2 and the longitudinal beam 11 is prevented.
The running gear 2 is capable of running on the ground by using the crawler belt running mechanism 26 and is not restricted by the track. Moreover, the track-laying mechanism 26 can rotate in the horizontal direction, which improves the flexibility of the vehicle. The spacing between the two track rows 26 can be set according to the width of the switch, for example: 10 m. The transverse movement of the track unit 26 allows the barrier to clear obstacles on the ground.
The longitudinal beam 11 is provided with a double-power system 8 and a hydraulic system 9 which are used for providing power for the working vehicle. The two sets of power transmission systems are arranged in parallel at the middle position of the longitudinal beam 11 and share one engine room, and one set of power transmission system can be used for rescue. When one power system fails, the other power system can independently drive the whole machine to operate.
This embodiment still provides a switch shop and trades operating system, includes: the railway turnout laying and replacing operation vehicle, the flat car for transporting the railway turnout laying and replacing operation vehicle and the turnout transport vehicle for transporting turnouts complete turnout laying operation together. The switch shop changes the operating system that this embodiment provided has the same technological effect with above-mentioned railway switch shop changes the operation car.
