The invention discloses a lifting seat for welding of a large convex seal head in the field of seal head welding. The lifting seat comprises pulley sets and a seat body. The pulley sets comprise the fixed pulley set and the movable pulley set. A hanging hook capable of being hung on an edge opening of the seal head is arranged above the fixed pulley set, the fixed pulley set is connected with the hanging hook, and the movable pulley set is connected with the seat body. The seat body is provided with a fixed seat. A rope wind-up roller is arranged on one side of the fixed seat, and a drive device is arranged on the other side of the fixed seat. An output shaft of the drive device penetrates the fixed seat to be connected with the rope wind-up roller, and the rope wind-up roller can be driven to rotate forwardly or reversely. A rope is connected among the fixed pulley set, the movable pulley set and the rope wind-up roller in a winding manner, the rope wind-up roller rotates forwardly or reversely so that the rope can be wound or released to increase or decrease the distance between the fixed pulley set and the movable pulley set, and therefore the seat body ascends or descends. The lifting seat has the beneficial effects of being simple in structure, convenient to operate, high in safety and the like.
