The utility model provides a shield gantry car gyro wheel deviation correcting device belongs to the shield and constructs quick -witted technical field. A push rod is used for promoting the gyro wheel respectively, and three -position four -way electromagnetic valve and control system are connected, and signal generator and control system are connected, and signal receiver and control system areconnected for adjusting position that the gyro wheel of shield gantry car constructs trolley rail for the shield, including first regulations hydro -cylinder and second regulation hydro -cylinder, three -position four -way electromagnetic valve, remote control signal generator, signal receiver and control system, the push rod and the second regulation hydro -cylinder of first regulation hydro -cylinder . the utility model discloses the device aims at solving current shield and constructs can not in time adjust when the gyro wheel of shield gantry car takes place the incline in the quick -witted work progress and lead to the gyro wheel to fall, can only shut down the problem of adjustment, in time adjust roller location when this device can take place the incline at the gyro wheel of discovery shield gantry car, prevents that gyro wheel continuation incline from leading to the gyro wheel to fall.
