A load distribution optimization method for cooperative operation of two cranes

Abstract

The invention discloses a load distribution optimization method of double-crane collaborative operation, which comprises the steps that three-dimensional scene modeling is performed; crane model selection is performed; crane configuration is performed; double-crane collaborative lifting movement is calculated; double-crane collaborative lifting parameters are calculated; load distribution is optimized; a lifting target point is reached; and lifting is completed. According to the method, a relation model of rated load lifting capacity is established by analyzing influencing factors influencing the rated load lifting capacity, a real-time load model of each crane in a collaborative operation process is studied by analyzing the collaborative operation process and combining the dynamic characteristics of the cranes, and the load distribution is optimized simultaneously, so that the safety of a lifting process is improved.

Description

technical field [0001] The invention relates to the field of load distribution optimization of cranes, in particular to a load distribution optimization method for cooperative operation of two cranes. Background technique [0002] As an indispensable construction machinery, cranes play an important role in national economic construction such as petrochemical industry, electric power construction, water conservancy and hydropower, and bridge construction. With the rapid development of our country's economy, all walks of life in our country are in the ascendant, especially in metallurgy, nuclear power, docks and other aspects of construction scale is increasing, large-scale hoisting is increasing, and the operating environment is becoming more and more complex. A single crane often cannot meet the operating needs. Machine or multi-machine hoisting is increasing. [0003] At present, the hoisting of two machines often adopts the manual preparation of the hoisting operation pla...

Problems solved by technology

Moreover, the double-machine hoisting lacks effective and scientific theoretical guidance. Only relying on manual experience is subjective and one-sided, and cannot fully guarantee the safety of the hoisting operation, and the efficiency is very low, which increases the cost of hoisting.

[0004] The double-machine hoisting operation is complicated. With the change of the speed and working position of the lifting point, the load acting on a certain lifting point may change, resulting in dangerous accidents such as arm breakage due to uneven load distribution.
