A liquid tank truck rollover buffer device and its control method

Abstract

The invention discloses a rollover buffer device for a liquid tanker and a control method thereof. The buffer device includes a high-pressure gas storage tank, a high-pressure air pump, a buffer umbrella, a gyro sensor, a high-pressure nozzle, a rollover buffer controller and an alarm controller. The buffer umbrella is set on the middle and upper parts of both sides of the tank body of the liquid tanker, the gyro sensor is installed on the trailer chassis at the center of the tank body, and the high-pressure nozzle is installed at the center of the buffer umbrella and fixed on the outside of the tank body. The control method includes: when the monitored roll angle is smaller than the threshold K, the tanker runs normally, continues to collect and analyze data, but does not output a control signal; when the monitored roll angle is greater than the threshold K, triggers the rollover buffer device , the rollover buffer controller adjusts the angles of the high-pressure nozzles on both sides respectively, keeps the high-pressure nozzles on one side of the rollover always in a vertical position, and the high-pressure nozzles on the other side is always in a horizontal position, and controls the high-pressure nozzles on both sides to spray into the buffer umbrella at the same time into the high pressure gas.

Description

technical field [0001] The invention relates to the transportation safety of liquid tank trucks, in particular to a rollover buffer device for liquid tank trucks and a control method thereof. Background technique [0002] Hazardous chemicals are mainly transported by road by hazardous chemical transport vehicles, and tank trucks are the most widely used. With the development of tank truck transportation, the requirements for its safety and stability have been further improved. Rollover accidents frequently occur during the transportation of liquid tank trucks, which will not only cause traffic jams, but also endanger the lives of drivers. When the liquid tank truck rolls over, the tank body is prone to damage, resulting in leakage of the medium in the tank, resulting in waste of resources, polluting the environment, and endangering the surrounding population. Due to the differences in the experience and driving skills of different drivers, the driver will not be able to de...

AI Technical Summary

Problems solved by technology

The vertical telescopic bracket installed under the chassis can provide timely support and cushioning when the vehicle rolls over at a small angle, but when the vehicle rolls over at a large angle in an instant, the vehicle will even turn around the contact point between the device and the ground, which cannot provide cushioning effect

The side pop-up bracket can be adjusted according to the vehicle to meet the buffering needs of any rollover state of the tank truck. However, due to the large mass of the tank truck when fully loaded, the bracket needs to extend a large amount, which will affect the normal driving of vehicles in adjacent lanes
