Mobile polling method and device of coal mine vertical shaft

The invention discloses a mobile polling method and device of a coal mine vertical shaft. The mobile polling method comprises the steps: a, a vertical shaft lifting system provides a carrier, an image acquisition device is arranged on a tank cage of the lifting system, the image acquisition device comprises a plurality of CCD cameras or a plurality of camera devices and is used for acquiring image data of a vertical shaft facility when moving upwards or downwards with the tank cage, the vertical shaft facility comprises a shaft wall, a tank beam, a tank tunnel and other devices; and b, the image acquisition device carried by the tank cage automatically shoots images according to set mobile distance, and processes the obtained image data, and judges whether potential safety hazards exist in the vertical shaft according to a processing result. According to the invention, under the condition that the normal operation state of the vertical shaft lifting system is not influenced, complete-picture information of the shaft wall, the tank beam, the tank tunnel and other vertical shaft facilities can be obtained, and obtained images are analyzed through a computer, whether the potential safety hazards exist in the vertical shaft is judged, and automation and informatization of polling inspection of the vertical shaft are realized.
