Rail car for subway cable laying

The utility model discloses a rail car for subway cable laying. The rail car comprises a rail car body, wherein a cable drum, a cable drum driving system, a pay-off arm and a pay-off arm driving system are arranged on the rail car body; the wire coil driving system is used for driving a cable wire coil to rotate; the pay-off arm driving system is used for driving the pay-off arm to lift and rotate; the wire coil driving system and the pay-off arm driving system are both electro-hydraulic driving systems. An energy accumulator is arranged in the electro-hydraulic driving system and connected with a pipeline at the outlet end of a hydraulic pump in the electro-hydraulic driving system, and when the hydraulic pump works, the energy accumulator can store pressure energy from the hydraulic pumpand can release energy to an executing mechanism in the electro-hydraulic driving system. The structural design of the rail car is convenient to match with the power required by cable laying. 本实用新型公开了一种用于地铁电缆敷设的轨道车，包括轨道车本体，所
