The invention provides a steel reinforcement cage self-positioning binding tool applicable for high speed railway ballastless track plates. The steel reinforcement cage self-positioning binding tool applicable for the high speed railway ballastless track plates comprises a binding table, a plurality of conveying devices are installed below the binding table, T-shaped track wheels in the conveying devices are matched with a channel track in the binding table, a blocking device is installed in the front of the binding table, a lifting deice is installed behind the binding table, and a jacking device is installed below the lifting device. According to the steel reinforcement cage self-positioning binding tool applicable for the high speed railway ballastless track plates, automatic positioning and installing of steel reinforcement cages and prestressing tendons are achieved, binding of the steel reinforcement cages is completed in the binding table by workers, the prestressing tendons are put to the position according to rules, and a complete steel reinforcement cage whole with accurate space sizes are formed; and positioning is accurate, labor intensity of the workers is reduced, and working efficiency is greatly improved.
