Engineering machinery anti-tipping control system and control method thereof

Abstract

The invention discloses an engineering machinery anti-tipping control system and control method thereof. The control system comprises an inclination angle sensor, a comparator and a controller, the deviation angle of the engineering machine is obtained by processing an inclination angle detection signal of the engineering machine, the comparator judges whether the deviation angle deviates from anadjusting threshold value or not, the controller further judges and processes the deviation angle; and the engineering machine is controlled by the instruction to timely lock dangerous actions and timely control the adjusting actions of support legs and a suspension arm of the engineering machine, so that the engineering machine is always in a balanced safety state, and the tipping accident of theengineering machine is avoided.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to an anti-overturn control system and a control method for construction machinery. Background technique [0002] Construction machinery, such as cargo cranes, fire trucks, concrete pump trucks, and earth excavation trucks, etc., due to the need to lift the arm or cantilever during the work process, it is more common to cause the center of gravity of the chassis to deviate in case of an emergency, resulting in tipping events. Appropriate anti-rollover control measures are required. [0003] The existing anti-rollover control technology mainly has the following two types: one is to focus on the influence of the position of the center of gravity of the vehicle on the rollover, and judge whether a certain operation has a favorable or unfavorable impact on the movement of the center of gravity of the vehicle To determine whether there is a danger of overturning, this i...

[0003] The existing anti-rollover control technology mainly has the following two types: one is to focus on the influence of the position of the center of gravity of the vehicle on the rollover, and judge whether a certain operation has a favorable or unfavorable impact on the movement of the center of gravity of the vehicle To determine whether there is a danger of overturning, this is based on the idea of ​​overall anti-overturning, and it needs to be judged after the operation has been implemented, which has hysteresis; second, by detecting the outrigger pressure, when the outrigger pressure is greater than the maximum value or less than the minimum value, through the corresponding relationship between the moment from the center of gravity of the vehicle chassis to the tipping edge and the moment from the center of gravity of the vehicle to the tipping edge, an outrigger alarm message is issued to remind the operator to pay attention, but in the actual process In the process, the operator sometimes fails to pay enough attention to the alarm information of the outrigger or does not have time to correct the wrong action, which causes the truck crane to overturn, and at the same time brings significant economic losses and casualties
