Specific embodiment
Technical solution in order to enable those skilled in the art to better understand the present invention, in the following with reference to the drawings and specific embodiments
It elaborates to the present invention.
Embodiment of the invention discloses a kind of platform angle electronic intelligence leveling system applied to aerial work platform,
As shown in the figure comprising main electric slope angle sensor 1, secondary electric slope angle sensor 2, floor push 3, manual leveling override switch
4, controller 5, leveling cyclinder proportional control solenoid valve 6, platform leveling cyclinder 7, acoustic-optic alarm 8, platform 9, principal arm 10, master
Arm elevating ram 11, vehicle 12, bracket 13, folding arm 14 and operating device 15,
The inside of vehicle 12 is equipped with controller 5, and the top of vehicle 12 is respectively equipped with principal arm 10 and principal arm elevating ram 11；It is main
The rear end of arm 10 is connect by pin shaft with the top of vehicle 12；The rodless cavity of principal arm elevating ram 11 and the top pin shaft of vehicle 12
Connection；The rod chamber of principal arm elevating ram 11 is fixedly connected with the bottom end of principal arm 10；The head end of principal arm 10 is set by pin shaft connection
There is folding arm 14, platform leveling cyclinder 7 is equipped between principal arm 10 and folding arm 14；The other end of folding arm 14 is connected with by bracket 13
Platform 9.
In the present embodiment, the inner bottom of platform 9 is equipped with floor push 3；The outside of platform 9 is on the side of folding arm 14
Portion is fixed with operating device 15；Operating device 15 is equipped with manual leveling override switch 4 and acoustic-optic alarm 8；Outside platform 9
Side is fixed with leveling cyclinder proportional control solenoid valve 6；Leveling cyclinder proportional control solenoid valve 6 is in the top of bracket 13；Branch
The two sides of frame 13 are fixed with main electric slope angle sensor 1 and secondary electric slope angle sensor 2 respectively.
