The invention discloses a high-speed pantograph head with double contact strips. The high-speed pantograph head comprises an upper top pipe (1), sleeves (2), two pantograph horns (3) and two spring supports (4); two sets of spring pieces are symmetrically arranged at the two sides of each spring support (4), each set of spring pieces is composed of the upper spring piece (5) and the lower spring piece (6) in parallel, and the ends of the spring pieces in each set are connected with one contact strip support (7); every two contact strip supports (7) located at the same side of the upper top plate (1) are provided with one contact strip (8), and namely the two contact strips (8) are symmetrically arranged at the two sides of the upper top plate (1). Several sets of simple spring pieces installed symmetrically are used for replacing an original complex spring hanging system, the high-speed pantograph head has the advantages of being light and good in aerodynamics performance. The two contact strips are used, and lighter contact strips can be used, and the following performance of the pantograph can be greatly improved.
