Automatic leveling and positioning device and method for cable crane

The invention discloses an automatic leveling and positioning device and method for a cable crane, thereby realizing automatic positioning and assembling of steel box girder sections to be assembled and assembled steel box girder sections during cable crane bridge construction. Bearing cables are arranged at the two ends of a cable crane bridge in a connected mode. The device comprises a bearing transportation device used for moving to-be-assembled steel box girder segments towards assembled steel box girder segments, a position monitoring device for monitoring the position information of thesteel box girder sections to be assembled, and a control unit for receiving the position information transmitted by the position monitoring device and controlling the to-be-assembled steel box girdersections and the assembled steel box girder sections to be in automatic butt joint and installation. The device and method have the technical effects that automatic butt joint of the steel box girdersections is achieved, the b
