The invention provides an unwinding operation vehicle for subway overhead lines. The unwinding operation vehicle comprises a vehicle rack, wherein bogies, a hoisting clamp, an electrical system, an air braking system and a rail clamp are arranged under the vehicle rack; a vehicle hook and a lifting hook are respectively arranged at both ends of the vehicle rack; a vehicle body is arranged at the end I of the upper end surface of the vehicle rack, and a wire support is arranged at the top of the vehicle body; unwinding devices are arranged at the end II of the upper end surface of the vehicle rack; a hydraulic system is arranged on each unwinding device; any of the width of an unwinding rack in each unwinding device, and the width of the vehicle body is smaller than the width of the vehicle rack; the vehicle body and the winding devices are respectively and eccentrically arranged on the upper end surface of the vehicle rack on the same side, so that a working corridor is formed on the other side of the upper end surface of the vehicle rack, and a balance weight is also arranged on the other side of the vehicle rack. In the unwinding operation vehicle disclosed by the invention, three unwinding device sets can perform operation of multiple working points at the same height and at different positions, and each winding device set can also be independently controlled to work; besides, the mounting of each component of the whole vehicle meets requirements for subway operation environment and running, so that the maintenance operation for subway overhead lines is simple and high-efficient.
