The invention discloses a structure capable of mounting and dismounting a balancing weight automatically by a tower crane. The structure comprises a lifting mechanism (11), a lifting pulley (12), an automatic balancing weight device (14) and a steel wire rope (13), wherein the lifting mechanism is installed on a balance arm (16); the automatic balancing weight device (14) comprises a support (21), a first upper pulley (22) and a second upper pulley (23) which are installed on the support (21), a lower pulley (24) which is positioned below the first upper pulley (22) and the second upper pulley (23) and is connected with a balancing weight (15); the steel wire rope (13) starts from the lifting mechanism (11), sequentially bypasses the lifting pulley (12), the second upper pulley (23), the lower pulley (24) and the first upper pulley (22), winds back and is fixed on the lifting mechanism (11). The lifting mechanism of the tower crane acts as a power source, so that the balancing weight can be stably and conveniently mounted and dismounted.
