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 over, 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...

Abstract

The invention discloses a control method and device for preventing an engineering machine from overturning, and an engineering machine. The method comprises the following steps of: obtaining the positions of all supporting legs of the engineering machine and the supporting force of all the supporting legs; obtaining the gravity of the whole machine according to the supporting force of each of the supporting legs; calculating out the center-of-gravity position of the whole machine according to moment equilibrium; determining the overturning side; obtaining a safety coefficient according to the corresponding relation between the moment from the chassis of the whole machine to the overturning side and the moment from the center of gravity of the whole machine to the overturning side; and locking the engineering machine when the safety coefficient is smaller than the minimum value of the set range value. The method disclosed by the invention has the beneficial effects that the safety coefficient is obtained in real time, and whether the engineering machine can overturn or not is judged through the comparison of the safety coefficient and the set range value, so that the engineering machine can be detected in real time; in addition, whether the engineering machine can overturn or not can also be judged when the supporting legs are not completely unfolded, so that the safety of the engineering machine is improved.

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...
