The invention discloses engineering equipment as well as an overall stability detection method and a device of the engineering equipment. The engineering equipment comprises a chassis as well as support legs and a rotary center on the chassis. The overall stability detection method comprises the following steps: after the support legs are unfolded, measuring relative positions of vertical cylinders of the support legs and the rotary center; detecting the pressure to the vertical cylinders of the support legs; calculating available moment of the engineering equipment according to the relative positions and the pressure; calculating present impact moment according to change of pressure to the vertical cylinders of the support legs; confirming an allowable moment threshold according to the impact moment; confirming the overall state of the engineering equipment according to the allowable moment and a preset allowable moment threshold. Therefore, by calculating the resultant force and action points of the whole equipment, the gravity and the centre-of-gravity position of the equipment are confirmed, and furthermore the overall stability state of the engineering equipment is confirmed.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to an engineering equipment and a method and device for detecting the stability of the whole machine. Background technique [0002] For construction machinery and equipment, especially cranes, accurately measuring and judging the center of gravity of the equipment can prevent tipping accidents, which is very important for safe production. Truck cranes usually use working condition tables (such as limits on amplitude and hoisting capacity) to indicate the stability of the equipment. On the production site, due to the measurement error of the amplitude and the hoisting capacity, occasional instability and tipping accidents occur, which are mainly caused by the accumulation of errors in the weight and center of gravity measured during design, manufacture, and work. [0003] At present, in order to avoid equipment overturning accidents caused by such errors, a large stability safet...
