A liquid tank truck rollover support device and its rack elongation control method

Abstract

The invention discloses a rollover support device for a liquid tank truck and a method for controlling elongation of a rack thereof. The rollover support device includes a first rack, a second rack, a rollover monitoring unit, a horizontal movement mechanism, a vertical movement Mechanism, alarm controller and rollover support device controller, the horizontal movement mechanism includes the first motor, the first pawl, the first ratchet, the first gear and the first auxiliary pulley, the vertical movement mechanism includes the second motor, the second ratchet pawl, second ratchet, second gear and second auxiliary pulley. The control method is as follows: when the monitored roll angle is less than the calibrated threshold K, the vehicle runs normally, and the rollover monitoring unit continues to collect data but does not output a control signal; when the monitored roll angle is greater than the calibrated threshold K , the rollover support controller outputs a control signal to control the extension of the first rack and the second rack, and at the same time controls the alarm control unit to give an alarm.

Description

technical field [0001] The invention relates to the transportation safety of liquid tank trucks, in particular to a rollover support device for liquid tank trucks and a method for controlling elongation of racks thereof. Background technique [0002] As the main means of transport for hazardous chemicals, liquid tank trucks have a wide range of applications and require high safety and stability. However, during the transportation of hazardous chemicals, major traffic accidents such as liquid tank truck rollovers often occur, which will not only cause traffic jams, but also endanger the lives of drivers. The tank body of the liquid tank truck is prone to damage when it rolls over, causing the medium in the tank to leak, resulting in waste of resources, polluting the environment, and endangering the surrounding people. When the vehicle rolls over, because many drivers are inexperienced and cannot handle it in time, the rollover is often unavoidable. Therefore, it is necessar...

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

The lateral horizontal telescopic outrigger support device is also installed under the chassis, which can be stretched out in time to support the liquid tank truck when it rolls over. However, due to the limitation of road width, the extension of the outrigger cannot be too long. Hours outriggers cannot touch the road in time, unable to play a supporting role
