Clamping device for locomotive mounting

The invention relates to the technical field of mounting clamps and particularly discloses a clamping device for locomotive mounting. The clamping device comprises a clamping part and a clearing part.The clamping part comprises a vertical shaft, and racks are fixed to the two sides of the vertical shaft. The racks are engaged with gears, and clamping rods are eccentrically fixed to the end facesof the gears. A clamping plate is fixed to the other end of each clamping rod, and the clearing part comprises an air-blowing part and a clearing rod. The air-blowing part comprises a cylinder body and a pushing rod, and a piston is slidably connected in the cylinder body and divides the cylinder body into an upper cavity and a lower cavity. A piston rod is fixed to the piston, and the other end of the piston rod is fixed to the pushing rod. An air outlet is formed in the side wall of the lower cavity, and an air outlet pipe communicating with the clearing rod is arranged at the air outlet. The clearing rod is located
