A load distribution method for cooperative operation of two cranes

Abstract

The invention discloses a method for allocating load to double cranes cooperatively operating. The method for allocating the load to the double cranes cooperatively operating includes the following steps of three-dimension scene modeling, crane type selection, crane configuration, calculation of cooperative hoisting motion of the double cranes, calculation cooperative hoisting parameters of the double cranes, hoisting objective point reaching, and end of hoisting. According to the method for allocating the load to the double cranes cooperatively operating, firstly, a relation model of rated load lifting capacity is established through analysis of influencing factors of the rated load lifting capacity, secondly, a real-time loading model of each crane in the process of cooperative operation is researched through combination of analysis of the process of the cooperative operation and crane dynamics characteristics, and therefore safety performance of the hoisting process is improved.

Description

technical field [0001] The invention relates to the field of load distribution of cranes, in particular to a load distribution 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 plan, and the hoisting is com...

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.
