The invention discloses static spraying equipment applicable to different locomotive door sizes. The equipment comprises feeding mechanisms, spraying guns, and reciprocating mechanisms connected to the feeding mechanisms. The equipment further comprises telescopic mechanisms arranged between the spraying guns and the reciprocating mechanisms. The fixed ends of the telescopic mechanisms are connected with the reciprocating mechanisms. The spraying guns are arranged at the free ends of the telescopic mechanisms. The telescopic length of the telescopic mechanisms is regulated according to the locomotive door size, accordingly, the positions of the spraying guns are regulated, the problem that the door type static spraying equipment operating locomotive type size is simplex and limited is solved, the one set of equipment can be used for spraying locomotive types with different sizes, and the equipment application range is greatly expanded.
