Control device and control method for coordination hoisting of crawler cranes

Abstract

A control device for coordination hoisting of crawler cranes comprises a hoisted object gesture detection and data processing transmission module and at least two coordination control and display modules. The hoisted object gesture detection and data processing transmission module is arranged on an object to be hoisted, and is used for collecting and processing the gesture information of the object to be hoisted and transmitting the processed information to the coordination control and display modules. The coordination control and display modules are mounted in crane control rooms respectively and are respectively used for receiving the gesture information of the object to be hoisted sent by the hoisted object gesture detection and data processing transmission module. Meanwhile, all the coordination control and display modules interact the hoisting weight, the hoisting height and the hoisting speed of respective cranes which the coordination control and display modules belong to in a wireless communication mode. By means of the control device for coordination hoisting of the crawler cranes, large-tonnage heavy goods can be hoisted through cooperation of low-cost and low-tonnage crawler cranes, cost is greatly lowered, meanwhile, parameters can be displayed on a display screen in real time, and thus the device is more user-friendly.

Description

technical field [0001] The invention relates to electrical control technology, in particular to a control device and control method for coordinated hoisting of crawler cranes. Background technique [0002] With the construction scale of nuclear power, petroleum, chemical industry, shipbuilding and other major projects becoming larger and shorter, in order to improve the construction quality and efficiency of project construction, requirements are put forward for the hoisting of modular overall structures, and lifting A super large tonnage crawler crane with a capacity of over 3,000 tons. Super-large tonnage crawler cranes are complex in structure and control, expensive, and the total demand is not large. After the project is completed, it is easy to cause idle equipment and waste of resources. Intelligent coordinated control is the development trend of construction machinery. [0003] After searching the literature of the prior art, no literature related to the coordinated...

Problems solved by technology

But there are the following deficiencies: [1] The same main controller is used to control each motor, which belongs to the multi-axis control of the same equipment, which cannot meet the coordinated movement between different main equipment; [2] It mainly completes the speed of each movement axis Coordination, but no coordination control between displacement and force
