Automatic anti-tilting control system for automotive hydraulic lifting

Abstract

The invention discloses an automatic anti-tilting control system for automotive hydraulic lifting, which comprises a lifting valve, a single chip microcomputer controller, a tilt angle sensor, a proximity switch, a lifting gas circuit electromagnetic valve, a quick release gas circuit electromagnetic valve and a slow release gas circuit electromagnetic valve, wherein the proximity switch is arranged on a chassis sub-frame, and the lifting gas circuit electromagnetic valve, the quick release gas circuit electromagnetic valve and the slow release gas circuit electromagnetic valve are connected with a lifting pneumatic control port, a quick release pneumatic control port and a slow release pneumatic control port of the lifting valve respectively. Detecting signals of the tilt angle sensor are inputted into the single chip microcomputer controller, a safety signal output end and a danger signal output end of the single chip microcomputer controller are connected with the lifting gas circuit electromagnetic valve and the quick release gas circuit electromagnetic valve respectively, and two contacts of the proximity switch are connected with the quick release gas circuit electromagnetic valve and the slow release gas circuit electromagnetic valve respectively. When an automobile tilts, the tilt angle sensor outputs the signals, a display screen is used for displaying danger signals, a voice display alarm is used for prompting danger, and the single chip microcomputer controller is used for outputting the danger signals and forcibly stopping lifting, so that a carriage descends to a safety position, and side overturning due to titling is avoided.

Description

technical field [0001] The invention relates to an automobile control system, in particular to an automobile hydraulic lift anti-tilt control system. Background technique [0002] In the prior art, the lifting, fast release and slow release of the piston rod of the hydraulic cylinder are mainly realized by a manual air control valve installed in the cab. The manual air control valve mainly has three control positions. Connect the lift control position on the manual air control valve to the lift air control port of the lift valve, and connect the quick release control position on the manual air control valve to the quick release control position of the lift valve. Connect the air release control port, connect the slow release control position on the manual air control valve to the slow release air control port of the lift valve. When the car stops at the place where the cargo needs to be unloaded, open the lift control position on the manual air control valve, the air pressu...

Problems solved by technology

[0003] When unloading the goods in the cargo compartment through the above method, when the hydraulic lift is performed, the operator's improper operation, lack of work experience or subsidence of the road surface contacted by the tires often cause vehicle rollover accidents during unloading, causing serious damage to the unit or the user. economic loss and personal injury
