Tilting-preventing system for sanitation vehicle and sanitation vehicle

Abstract

The invention discloses a tilting-preventing system for a sanitation vehicle. The tilting-preventing system comprises a stroke valve which is arranged between an air source and a lifting air valve. The air source and the lifting air valve are cut off when the stroke valve is not triggered, and the stroke valve can be triggered exactly when a rear door of the sanitation vehicle is opened in place.Two gas ways of the lifting air valve communicate with a lifting hydraulic valve, the lifting air valve is located in different stations so that the lifting hydraulic valve can be controlled to be located in different stations, the flowing directions of gas in the two gas ways are changed, the lifting hydraulic valve can be located in different stations to change the flowing directions of hydraulic oil, the flowing directions of the hydraulic oil are different so that the movement directions of lifting oil cylinders can be different, and the lifting oil cylinders are controlled to stretch or retract. By means of the tilting-preventing system for the sanitation vehicle, the lifting air valve is used for controlling the lifting hydraulic valve, so that ascending and descending of the liftingoil cylinders are controlled, when the stroke valve is not triggered, gas cannot be supplied to the lifting air valve, airflow is not output even if the lifting air valve is located in the lifting station, and a garbage bin cannot achieve the ascending and descending operation. The invention further provides the sanitation vehicle comprising the above tilting-preventing system for the sanitationvehicle.

Description

technical field [0001] The invention relates to the technical field of sanitation vehicles, and further relates to an anti-tilt system for sanitation vehicles. In addition, the invention also provides a sanitation vehicle. Background technique [0002] When a sanitation vehicle with a dumping box dumps garbage, the rear door is opened first, and the ejector rod at the bottom of the dumping box is extended to lift the dumping box, so that the dumping box is tilted backward, and the garbage has a tendency to move downward under the action of gravity. After the dump box is lifted to a certain angle, the component force of gravity is greater than the friction force, and the garbage is poured out from the opened rear door. [0003] In actual operation, if the dumping box is directly lifted without opening the back door due to negligence, the garbage in the box will accumulate at the back door, which will make the overall gravity distribution unbalanced. The rear wheel of the ve...

Problems solved by technology

[0003] In actual operation, if the dumping box is directly lifted without opening the back door due to negligence, the garbage in the box will accumulate at the back door, which will make the overall gravity distribution unbalanced. The rear wheel of the vehicle is the fulcrum, and the front direction is lifted up, which brings hidden dangers to the safety of the operator, and is also very easy to damage the sanitation vehicle
