Towing device based on tank truck rollover prevention, and control method of towing device

Abstract

The invention discloses a towing device based on tank truck rollover prevention, and a control method of the towing device. The towing device is provided with a control module, a disc-type groove supporting device, and a ball head towing device additionally provided with two electronic hydraulic cylinders; the two electronic hydraulic cylinders get close to a trailer part, meanwhile an in-out opening is formed in the disc-type groove supporting device, influences caused when a trailer and a towing vehicle are connected and the vehicle turns are avoided, the free stroke of the electronic hydraulic cylinders is set in the disc-type groove supporting device, and the state of generating normal jolt under the vehicle operating state is not influenced; and the rollover angle of a tank truck is monitored through the control module, when the tank truck is about to roll over, the control module calculates the heights, needing to the enlarged, of the electronic hydraulic cylinders in real time according to the rollover angle and emits signals, the electronic hydraulic cylinders receive the signals, lifting rods are ascended to accurate heights to support the vehicle, and the problem that asfor an existing towing device, when the rollover angle of the vehicle is too large or too small, supporting cannot be achieved is solved effectively.

Description

technical field [0001] The invention belongs to the field of semi-trailer liquid tank vehicles, and in particular relates to a traction device and a control method for preventing liquid tank vehicles from tilting and rollover. 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 o...

Problems solved by technology

This method is only to disengage the tractor from the trailer after the vehicle rolls over, so as to avoid personal injury to the driver. Like the above method, it cannot implement active control under the dangerous working conditions that the vehicle is about to roll over or roll.
