Measuring device for radial structure of ferris wheel

The utility model discloses a measuring device for a radial structure of a ferris wheel, which comprises at least one laser range finder (101) installed on a axle of the ferris wheel or a hub at the near end of the axle and laser reflective sheets (102) which are installed on a wheel disk of the ferris wheel and correspond to the laser range finders (101) in one-to-one mode. All laser range finders (101) are in circuit connection with a wireless signal emitter (103), the wireless signal emitter (103) is matched with a wireless signal receiver (104), and the wireless signal receiver (104) is in circuit connection with a communication host (105). The measuring device can measure whether the ferris wheel has structural distortion and whether the structural distortion exceeds a safety range.
