Laser emitter 1 and laser detector 2 are all installed on the axle tunnel inner wall, are provided with transmission shaft B in the axle tunnel. The main control board 3 controls the laser emitter 1 to work, the laser emitter 1 emits laser, the laser detector 2 is located on a set light path of the laser in the shaft tunnel, and on the set light path, a transmission shaft B which does not generate obvious bending is located between the laser emitter 1 and the laser detector 2. Therefore, under the condition that the transmission shaft B is not bent obviously, the laser detector 2 cannot receive the laser emitted by the laser emitter 1, and the laser detector 2 cannot emit signals to the main control board 3. Once transmission shaft B produces obvious crooked, then transmission shaft B crooked part will dodge laser formation, and laser detector 2 just can receive the laser that laser emitter 1 sent, and laser detector 2 can signal to main control board 3, by the work of main control board 3 control alarm 4, reminds maintainer in time to look over the maintenance to transmission shaft B, need not wait to regularly inspect or produce obvious trouble next time.
