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...

Examples

Embodiment Construction

[0020] Take the direction close to the pop-up rollover buffer umbrella 3 as the top, the direction close to the wheel of the liquid tanker as the down, the direction close to the front of the tractor as the left, and the end of the tanker away from the tractor as the right.

[0021] Such as Figure 1~2 , the liquid tanker includes a tractor, a tank body and a buffer device, and the buffer device includes a high-pressure gas storage tank 1, a high-pressure air pump 2, a high-pressure nozzle 5, a buffer umbrella 3 and a gyro sensor 4 for monitoring the real-time roll angle of the tank body of the liquid tanker , The buffer umbrella 3 is a pop-up rollover buffer umbrella, which can be arranged at any position on the upper semicircular surface of the tank body, and can be adjusted according to the shape of the tank body. The high-pressure gas storage tank 1 and the high-pressure air pump 2 are installed at the rear end of the tractor chassis, the pop-up rollover buffer umbrella is...
