Embodiment Construction
[0040] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0041] An embodiment of the present invention provides a control method for preventing construction machinery from tipping, and the control method for preventing construction machinery from tipping includes:
[0042] When the construction machinery is supported by the support legs, the support position information of each support leg and the support force of the support construction machinery are collected;
[0043] Obtain the vehicle gravity of the construction machinery according to the support force of each support leg supporting the construction machinery;
[0044] Calculate the position of the center of gravity of the construction machinery according to the ...

The invention discloses a control method, a control device and a construction machine for preventing overturning of construction machinery. The method includes: obtaining the position and support force of each support leg of the construction machine; obtaining the gravity of the whole vehicle according to the support force of each support leg; Calculate the position of the center of gravity of the vehicle according to the moment balance; determine the tipping edge; obtain the safety factor according to the corresponding relationship between the moment from the chassis of the vehicle to the tipping edge and the moment from the center of gravity of the vehicle to the tipping edge, and when the safety factor is less than the set When the range value is the minimum value, the construction machinery is locked. The beneficial effects of the present invention are: by obtaining the safety factor in real time, and judging whether the construction machinery will be in danger of overturning by comparing the safety factor with the set range value, the construction machinery can be detected in real time, and the support leg is not When it is fully opened, it can also be judged whether there is a danger of overturning of the construction machinery, which improves the safety of the construction machinery.
Description
technical field [0001] The invention relates to the technical field of anti-tipping of construction machinery, in particular to a control method, a control device and construction machinery for anti-tipping of construction machinery. Background technique [0002] Hydraulic outrigger construction machinery equipment, such as concrete pump trucks, truck cranes, high-altitude fire ladders, aerial work vehicles, etc., use outriggers to support the ground to form the largest safe operating area, and then extend the multi-section boom system to move the load Delivered to the target location. [0003] Accidental tipping of construction machinery and equipment poses a huge threat to equipment and personnel. There may be several reasons for this: the center of gravity of the structure is seriously shifted due to overload and other reasons during operation, the operation exceeds the safe operation area when the outriggers are not fully opened, The outriggers are unevenly loaded due t...
