Liquid tank truck rollover buffering device and control method thereof

Abstract

The invention discloses a liquid tank truck rollover buffering device and a control method thereof. The liquid tank truck rollover buffering device comprises a high pressure gas tank, a high pressuregas pump, buffering umbrellas, a gyroscope sensor, high pressure nozzles, a rollover buffering controller and an alarm controller; the buffering umbrellas are arranged at the middle upper parts of thetank sides of a tank body of a liquid tank truck; the gyroscope sensor is mounted on a trailer chassis in the central position of the tank body; and the high pressure nozzles are mounted at the centers of the buffering umbrellas and fixed to the external side of the tank body. The control method comprises the steps of enabling the liquid tank truck to normally run when a monitored roll angle is less than a threshold value K; continuing to collect and analyze data, but not outputting a control signal; when the monitored roll angle is larger than the threshold value K, triggering a rollover buffering device; enabling the rollover buffering controller to correspondingly adjust angles of the high pressure nozzles on the two sides; keeping the high pressure nozzle on one side of rollover to bealways in a vertical position and the high pressure nozzle on the other side of rollover to be always in a horizontal position; and controlling the high pressure nozzles on the two sides to simultaneously spray high pressure gas into the buffering umbrellas.

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
