The invention relates to the field of tunnel construction equipment, in particular to a ventilation device for urban rail transit tunnel construction, which comprises a mounting plate, a hanging mechanism, a fixing mechanism and a ventilation pipeline, and the hanging mechanism, the fixing mechanism and the ventilation pipeline are arranged below the mounting plate. According to the ventilation device for urban rail transit tunnel construction, the height can be adjusted according to the situation of the inner wall of a tunnel, the ventilation device can adapt to complex terrains, the erection difficulty is lowered, the ventilation device can conveniently stretch into a pipe barrel according to the construction progress, ventilation on a construction face is facilitated, and meanwhile, entered air can be changed for ventilation; according to the air purifier, ventilation in different directions is facilitated, meanwhile, a pipe barrel is prevented from dragging and pulling a rear pipeline when stretching into
