Dual pneumatic motor synchronous window wiper for railway locomotive

Abstract

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.

Description

technical field [0001] The invention relates to a pneumatic rain wiper, in particular to a dual air motor synchronous wiper for rail locomotives. Background technique [0002] Rail locomotives are the same as all motor vehicles, and their windshields are designed with a wiper system for cleaning dust and other sundries on the windshields. There are mainly two forms of electric wiper and pneumatic wiper. [0003] The cleaning system of the front window glass of rail locomotives often adopts a pneumatic wiper. The driving mechanism of the pneumatic wiper is a swing cylinder, and the swing cylinder drives the scraper blade to wipe the front window glass of the locomotive. Usually two sets of wiper systems are installed on each front window glass, and the wiping speed of the two sets of wiper systems is determined by the oscillation frequency. Due to the compact layout of the equipment in the locomotive cab, it is impossible to use a connecting rod between the two sets of wipe...

AI Technical Summary

Problems solved by technology

Due to the compact layout of the equipment in the locomotive cab, it is impossible to use a connecting rod between the two sets of wiper systems to ensure the synchronization of the operation of the two sets of wiper systems, so there is a slight difference in the wiping speed between the two sets of wiper systems. As the number of wiping increases, the operator will feel the difference in wiping speed between the two sets of wiper systems, that is, the operation is out of sync, which makes the operator feel dizzy
