Sanitation vehicle front spraying frame lifting device and lifting method

Abstract

The invention discloses a sanitation vehicle front spraying frame lifting device and lifting method. The device comprises a connecting base, a lifting mechanism and a front spraying frame; the liftingmechanism is connected to the connecting base, the front spraying frame is connected to the lifting mechanism and driven by the lifting mechanism to ascend and descend, and the device is characterized in that a distance sensor is fixed to the bottom of the front spraying frame; the distance sensor detects the distance between a nozzle on the front spraying frame and the ground in real time and feeds back the distance to the controller, and the controller controls the lifting mechanism to ascend and descend so as to drive the nozzle on the front spraying frame to be adjusted to a preset height. The distance sensor is installed on the front spraying frame installed at the front end of the sanitation truck chassis, the distance sensor senses the ground distance besides manual control over lifting and swinging of the front spraying frame, a feedback signal is transmitted to the controller, and the ground clearance of the front spraying frame is adjusted in the controller according to thefeedback signal value.

Description

technical field [0001] The invention belongs to the technical field of sanitation vehicles, in particular to a lifting device and a lifting method for a front spray frame of a sanitation vehicle. Background technique [0002] At present, the height of the front spray rack of the sanitation vehicle on the market can only be manually operated through the electric control box in the cab, and intelligent adjustment cannot be realized. Due to the large volume of water loaded in the tank of the sanitation vehicle, the water capacity in the tank is between full load and half tank. In the case of water and other conditions, the height of the nozzles at the front spray rack from the ground is different, and in order to achieve a better cleaning effect, the amount of overlap between the nozzles and the waterline is required. When the nozzle waterline overlaps too much, the impact force at the waterline overlap will be reduced, and the cleaning width will be reduced at the same time. I...

Problems solved by technology

[0002] At present, the height of the front spray frame of sanitation vehicles on the market can only be manually operated through the electric control box in the cab, and intelligent adjustment cannot be realized. Due to the large volume of water loaded in the tank of sanitation vehicles, the water capacity in the tank is between full load and half tank. In the case of water and other conditions, the height of the nozzles at the front spray rack from the ground is different, and in order to achieve a better cleaning effect, the overlap of the waterline between the nozzles and the nozzles is required

When the nozzle waterline overlaps too much, the impact force at the waterline overlap will be reduced, and the cleaning width will be reduced at the same time. If the nozzle waterline overlap is insufficient, there will be a problem that the gap between the adjacent nozzle waterlines cannot be cleaned.

The method adopted by the existing sanitation vehicle is to adjust the lowest point of the front spray rack to meet the nozzle waterline in the most suitable position when the tank is full of water, and when the water volume inside the tank decreases, the front spray rack will be raised from the ground. , the amount of waterline overlap between nozzles will increase, resulting in poor cleaning effect
