The invention discloses a pin penetrating oil cylinder support structure for boom joints of a tower crane boom. The pin penetrating oil cylinder support structure comprises a pin shaft (1), a pin penetrating oil cylinder and a support (5) fixed to the periphery of a pin shaft hole in a boom joint outer lug plate (3). The pin shaft (1) and the pin penetrating oil cylinder are arranged above the support (5), and the pin shaft (1) is connected with the stretching-out end of the pin penetrating oil cylinder. The pin shaft (1) moves in the pin shaft hole in the outer lug plate (3) along with stretching and contracting of the pin penetrating oil cylinder. When the boom joints are connected, the pin shaft penetrates the pin shaft hole along the oil cylinder support through the oil penetrating oil cylinder, and a lock pin is locked. During dismounting, the pin shaft is pulled out of the pin shaft hole along the support through the pin penetrating oil cylinder, and then the lock pin is locked. Connection of the boom joints is achieved, the pin shaft can be installed very easily and conveniently, and the installing difficulty is lowered; and meanwhile the damage to products during mounting and dismounting is reduced, the pin shaft and structural pieces are protected against damage, the producing and machining cost is reduced, the installing safety is improved, and the delivery usage is ensured.
