Abstract

The invention discloses a hybrid rail grinding wagon, which is applied to operation of hybrid rail grinding trains in the field of large-sized track engineering. The hybrid rail grinding wagon comprises an internal-combustion engine driven power car, an electrically driven power car and more than one trailer, wherein a grinding device is mounted on each trailer. When the hybrid rail grinding wagon is operated in a power accessible area or tunnel area, power is taken from a contact system through a pantograph of the electrically driven power car, subjected to voltage reduction with a transformer, and subjected to rectification and inversion with an inverter to generate three-phase variable-frequency variable-voltage alternating current, which is supplied as power required by a tractor motor and the grinding devices. The hybrid rail grinding wagon switches to the internal-combustion engine and generator combined mode in the power inaccessible area, so that power required by travelling and the grinding devices of the hybrid rail grinding wagon is supplied. The technical problem that existing grinding wagons are low in operation and combustion efficiency, severe in emission pollution and high in use and maintenance cost is solved, and the hybrid rail grinding wagon can achieve full-section seamless operation in the power accessible or in accessible area and the tunnel area.

Description

technical field [0001] The invention relates to a track maintenance vehicle used in the field of railway engineering, in particular to a rail grinding train with hybrid power used in the field of large-scale track engineering. Background technique [0002] Nowadays, the rail grinding vehicles at home and abroad are powered by internal combustion engines-generators. Vehicles using internal combustion engines as power sources generate a large amount of toxic gases and dust during operation, especially in tunnel operations. It will cause great harm to the health of the workers, and the exhaust gas and grinding dust will be difficult to discharge out of the tunnel. In severe cases, the engine will be shut down and the work efficiency will be reduced. In addition, the oil resources are increasingly scarce and the price is rising year by year, which makes the use cost A substantial increase. [0003] The internal combustion engine of the existing rail grinding car uses a diesel e...
