The invention discloses a flexible crawler-type pantograph head suitable for an electric traction locomotive. The flexible crawler-type pantograph head is characterized in that two metal rollers are arranged on a pantograph support, an insulating roller shaft is fixed on two roller supports, the two roller supports are fixed on the pantograph support, and the metal rollers are mounted on a rollershaft through two insulating bearings; a metal spring is arranged in at least one through hole in the roller shaft; a current collection carbon brush is fixed at each of the two ends, extending out ofthe through hole, of the metal spring; a flexible crawler belt is sleeved on the two metal rollers, more than one insulating supporting cylinder is arranged below the crawler belt, and the insulatingsupporting cylinder is structurally characterized in that a piston is fixed at the upper end of a movable supporting column and at the lower end of a supporting cylinder shaft and extends into an inner cavity of a supporting cylinder support to form an air cylinder, the supporting cylinder support is provided with a vent hole, and a limit spring is sleeved on the movable supporting column. The movable supporting column is arranged on the supporting cylinder support through a linear bearing. The flexible crawler-type pantograph head has the characteristics of good impact resistance, high current collection stability, large contact current collection area, low pantograph-catenary offline rate and the like.
