The present invention belongs to the technical field of electric pole production, specifically a device and method for automatically disassembling the
tension member at the end of a
reinforced concrete electric pole, comprising a frame, a
machine platform arranged above the frame, and a lifting mechanism that drives the
machine platform to move up and down; a nut loosening mechanism is slidably connected to the
machine platform along the axial direction of the electric pole, and the nut loosening mechanism includes a base slidably connected to the machine platform by a propulsion cylinder, a mounting plate vertically fixed to the base, a rotating disk rotatably connected to the mounting plate, and a pneumatic
wrench assembly radially symmetrically arranged on the rotating disk, a
laser sensor is also fixed on the rotating disk, and the
laser sensor is arranged in the radial direction of the
tension member; a fixing mechanism for fixing the
tension member is also provided on the machine platform. Before removing the nut, the present invention drives the
laser sensor to position the nut on the tension member by the rotating disk, and after positioning is completed, the nuts are removed one by one by the pneumatic
wrench to complete the automatic disassembly of the tension member, thereby greatly improving the disassembly efficiency.
