Tunnel detection robot and detection method

The invention discloses a tunnel detection robot and a detection method. A moving platform on the tunnel detection robot is provided with a supporting mechanism. A moving mechanism is arranged on the supporting mechanism and provided with a rotating mechanism. The rotating mechanism is provided with a base. A drive arm is arranged on the base. A rotating mechanical arm is arranged on the base. The rotating mechanical arm is provided with a jacking mechanism. The detection method of the tunnel detection robot comprises the following steps of (a) establishing a tunnel information work station, (b) measuring tunnel portal data, (c) lifting the tunnel detection robot, (d) locating the initial position of the tunnel detection robot, (e) obtaining tunnel detection information, (f) removing barriers in tunnel detection, (g) managing power in tunnel detection and (h) collecting and analyzing tunnel information. The tunnel detection robot has quite high obstacle climbing capacity and environment adaptive capacity and can obtain information data in the whole tunnel through one-time detection; and detection is rapid and simple, and detection precision is high.
