Multi-crane cooperative lifting operation method, device and crane

Abstract

The invention relates to a multi-crane cooperative lifting operation method and device, and cranes, wherein the operation method includes the steps: communication connection is established among various cranes; one crane is selected as a main machine from all the cranes, and the other cranes are selected as slave machines; in the lifting operation process, the main machine obtains lifting workingcondition information of all the cranes, and calculates the target lifting speeds of all the cranes according to the lifting work condition information; and all the cranes control themselves to operate with the corresponding target lifting speeds. The operation method achieves data sharing among all the machines, and has good real-time performance of information acquisition; the way of unified command of the main machine and distributed control of all the machines is beneficial for synchronizing the lifting speeds of hoisting hooks during operation of multiple machines, the relative stabilityof the lifting position is ensured, the lifting is prevented from generating unbalanced loading, the possibility of breaking or tipping of crane jibs and other risks is reduced, and the work efficiency and the hoisting safety can be improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a multi-crane cooperative lifting operation method, device and crane. Background technique [0002] A crane is a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane. Nowadays, all kinds of cranes have been widely used in urban construction, factory equipment hoisting, bridge construction and other occasions. Due to the variety of hoisting shapes and weights, multiple cranes are often required to coordinate hoisting operations. Such as figure 1 As shown, two cranes are ready for coordinated lifting operations. [0003] Such as the suspension bridge in the construction of viaducts and railway bridges, generally two cranes with the same or similar lifting capacity are required to lift at the same time, hoist it horizontally from the ground or a trailer, and then place it horizon...

AI Technical Summary

Problems solved by technology

[0007] The operators of each crane communicate with each other and then coordinate to make decisions according to their respective conditions, which is poor in real-time; the operators of each crane have poor real-time understanding of the status of the cranes of their companions, and there may be miscommands with each other, which is poor in safety; Labor costs, increased labor intensity
