Tank truck side turn supporting device and control method thereof

Abstract

The invention discloses a tank truck side turn supporting device and a control method thereof. The device is provided with a control system, a horizontal supporting rod and a vertical supporting rod,wherein the horizontal supporting rod is driven by a horizontal driving device; the vertical supporting rod is driven by a vertical driving device. The side-tipping angle of the tank truck is monitored by the control system, and when the tank truck has side turn, the horizontal supporting rod and the vertical supporting rod are controlled to rapidly extend out, so that the vehicle is supported, and the problem that the conventional device cannot be supported when the side-tipping angle of the truck is too small or too large is effectively solved; and due to the synergistic action of the two supporting rods, the supporting rods can contact with the ground without extremely long extension, and the influence to adjacent lanes can be avoided. According to the control method, by comparing the side-tipping angle of the tank truck and a threshold value K, when the side-tipping angle is more than or equal to the threshold value K, the supporting device is controlled to extend out and support;and when the side-tipping angle is less than the threshold value K, the supporting rods are actively retracted when the vehicle is straightened, the tank truck can conveniently run normally after danger treatment, the influence to trafficability is avoided, and support can be provided in time during subsequent side turn of the tank truck.

Description

technical field [0001] The invention relates to a liquid tank truck, in particular to a liquid tank truck rollover support device and a control method thereof. Background technique [0002] At present, the main ways of transporting hazardous chemicals include sea transport and land transport. Among them, the main carrier of land transportation is liquid tanker. When liquid tank trucks are speeding through corners or emergency avoidance, due to their high center of mass height and large load, major traffic accidents often occur when they roll over. The tank truck has a large size and load capacity, and when it rolls over, it will have a serious impact on the adjacent lanes, resulting in major accidents such as congestion and even serious rear-end collisions with multiple vehicles. In addition, most of the liquid tank trucks are loaded with dangerous chemicals. If leakage occurs during rollover, it will not only cause economic losses, but also endanger the lives of the surro...

AI Technical Summary

Problems solved by technology

But this kind of device can only play a supporting role when the vehicle roll angle is small. If the liquid tanker turns at overspeed or avoids at high speed, the lateral force on the vehicle is very large, and the device is difficult to play a supporting role.

In addition, the installation of the device under the chassis will affect the passability of the vehicle, which has certain potential safety hazards

Second, the lateral horizontal telescopic outrigger support device is also installed under the chassis, which can be stretched out in time for support when the tanker rolls over. However, due to the limitation of road width, the outrigger cannot be extended too long. When the roll angle is small, the outriggers cannot touch the road in time and cannot play a supporting role
