Problems solved by technology

[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.

Embodiment Construction

[0050] Such as figure 1 As shown, the method steps of an embodiment of the present invention are as follows:

[0051] Step 1: 3D scene modeling;

[0052] Step 2: Crane selection;

[0053] Step 3: Crane configuration;

[0054] Step 4: Calculation of the coordinated hoisting action of the two cranes;

[0055] Step 5: Calculation of the hoisting parameters of the two cranes;

[0056] Step 6: Reach the hoisting target point;

[0057] Step 7: Hoisting is finished.

[0058] In Step 1, the 3D scene modeling can be divided into two parts: 1) OpenGL provides the basic geometry for drawing; 2) Models with complex shapes need to be imported through third-party software to create model files.

[0059] The first part includes five basic geometric bodies: cuboid, cylinder, cone, torus, and sphere. We only need to provide the corresponding parameter input interface and interaction means, and the simulation system can call the model to build the scene.

[0060] The second part is mainly ...

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...
