The invention discloses a tunnel fan vibration detection device and method. The tunnel fan vibration detection device comprises a reflecting plate, a base, a first detection mechanism, a first display mechanism, a second detection mechanism and a second display mechanism. The first laser rangefinder and the second laser rangefinder are arranged towards the ranging part and turn to the reflecting part after ranging and positioning, and laser emitted by the first laser rangefinder and the second laser rangefinder is reflected by the reflecting part and displayed on the first display mechanism and the second display mechanism respectively. The vibration of the fan is converted into the motion trail of the laser on the display mechanism, and small vibration on the fan is amplified, so that observation is facilitated.
