Dual pneumatic motor synchronous window wiper for railway locomotive

The invention relates to a dual pneumatic motor synchronous window wiper for a railway locomotive. The dual pneumatic motor synchronous window wiper comprises a control switch, a control panel assembly, a left pneumatic motor, a right pneumatic motor, a left wiper arm, a right wiper arm, a wiper blade, a spraying mechanism and the like. The dual pneumatic motor synchronous window wiper is characterized in that two sets of pneumatic systems with the same structures are applied; the left and the right pneumatic motors and the left and the right wiper arms are respectively mounted at left and right front window glass of the locomotive; the left and the right pneumatic motors respectively drive the left and the right wiper arms and the wiper blade for wiping to clean the front window glass of the locomotive; no rigid connecting member is arranged between the left pneumatic motor and the right pneumatic motor; the left pneumatic motor and the right pneumatic motor are respectively operated to supply air for driving by the control panel assembly; photoelectric sensors are respectively arranged on the left pneumatic motor and the right pneumatic motor and are used for feeding back operation information of the left and right pneumatic motors to a control box on the control panel assembly; and the control box is used for controlling two-position five-way valves on the pneumatic motors for commutating according to a feedback signal, so that the commutating frequencies of the left and right pneumatic motors are ensured to be consistent, the mounting positions of the photoelectric sensors are identical and the running strokes of the left and right pneumatic motors are ensured to be consistent.
