The invention discloses a walking board connecting mechanism of a tower crane. The walking board connecting mechanism comprises a pair of lugs (1) welded to a crane upper support main structure (4), and installing shafts (2) welded to the two sides of a walking board stand column (3). The walking board stand column (3) is fixed into the lugs (1) on the crane upper support main structure (4) through the installing shafts (2). According to the walking board connecting mechanism of the tower crane, the lugs are welded to the upper support main structure, and the walking board stand column is hung in a connecting mechanism in clamping grooves of the lugs. The walking board connecting mechanism is simple in structure, low in cost, convenient to install, firm and stable. Usage of pin shafts is avoided, the coaxial precision of the pin shafts does not need to be guaranteed, the installing difficulty is lowered, and the installing efficiency is improved.
