WALL SURFACE TRAVELING DOLLY

Japanese Patent JP2015209172

A

PROBLEM TO BE SOLVED: To provide a wall surface traveling dolly in which the structure and control are simplified.SOLUTION: Projection members 11 projecting radially outward from the wheel outer periphery are attached to ring members 10 which can rotate integrally with magnetic attraction wheels 7a-7c and separate therefrom. A wall surface traveling dolly comprises separation mechanisms 15 for separating the projection members 11 from the rotation of the magnetic attraction wheels 7a-7c in a state in which the projection members 11 are not in contact with a wall surface W. When strikers 25a, 25b detect that the magnetic attraction wheels have come close to or into contact with a step part S, a control part 26 releases the separation of the projection members 11 from the rotation of the magnetic attraction wheels 7a-7c by the separation mechanisms 15. By this, the ring members 10 rotate integrally with the magnetic attraction wheels 7a-7c, the projection members 11 come into contact with the wall surface W, and the magnetic attraction wheels 7a-7c are separated from the wall surface. When the magnetic attraction wheels 7a-7c are separated from the wall surface W, a magnetic force to the wall surface W by the magnetic attraction wheels 7a-7c is reduced, and thereby the magnetic attraction wheels can ride on the step part S.
