Anti-overturning device and engineering machine

Abstract

The invention relates to the technical field of machinery and discloses an anti-overturning device and an engineering machine. The anti-overturning device is used for the engineering machine with legs and comprises a first acquiring unit, a computing unit, a first judging unit and a first processing unit, wherein the first acquiring unit is used for acquiring data of hoisted object weight, arm support length, arm support angle, weight of counter weights, rotation angle and off weight of the engineering machine, the computing unit is in signal connection with the first acquiring unit and used for computing the centre-of-gravity position of the engineering machine according to the data acquired by the first acquiring unit, the first judging unit is in signal connection with the computing unit and used for judging whether the subpoint of the centre-of-gravity position is located within a leg frame or not, and the first processing unit is in signal connection with the first judging unit and used for controlling the engineering machine to lock actions in the dangerous direction when the centre-of-gravity position is located outside the leg frame. Compared with the prior art, the anti-overturning device has the advantages that overturning of the complete machine due to failure in paying sufficient attention to leg alarming information or misoperation by an operator can be avoided, and accordingly heavy economic losses and risks of casualties are reduced beneficially.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an anti-overturning device and engineering machinery. Background technique [0002] The truck crane is a special engineering machinery integrating machinery, hydraulic pressure and electricity. During the operation process, the truck crane can transport the load to the designated position through actions such as luffing, slewing, and telescoping. In this process, the position of the center of gravity of the truck crane is constantly changing, therefore, corresponding devices need to be configured to prevent tipping. [0003] At present, in order to prevent anti-overturning, the outrigger pressure is generally detected. When the outrigger pressure is greater than the maximum value or less than the minimum value, an outrigger alarm message is sent to remind the operator to pay attention. However, in the actual process, the operator sometimes fails to pay enough attention to the ...
