Automatic unloading type window glass lifting system
The invention relates to an automatic unloading type window glass lifting system which comprises a lifting system and a decompressing system, wherein lifting branches are all communicated with oil branches, so that a lifting loop with oil flowing is formed; the lifting loop is used for switching an oil flowing direction in a pipeline through a three-position four-way solenoid valve and a two-position two-way solenoid valve, so that an ascending loop or a descending loop is formed; when each lifting switch is triggered, the lifting loop corresponding to the lifting switch starts to work; a motor, the three-position four-way solenoid valve, the two-position two-way solenoid valve and the lifting switch are all connected with a central controller; the decompressing system comprises a first decompressing branch and a second decompressing branch; after the first decompressing branch is communicated with the lifting system at an inlet pipeline of a lower chamber of a hydraulic cylinder, the first decompressing branch is connected with a check valve, a safety valve and a decompressing oil tank in turn; after the second decompressing branch is communicated with the lifting system at the inlet pipeline of an upper chamber of the hydraulic cylinder, the second decompressing branch is connected with the safety valve and the decompressing oil tank in turn.
