Hoisting coupling device with cooperation of multiple cranes and detection method

Abstract

The invention provides a hoisting coupling device with cooperation of multiple cranes and a detection method, and belongs to a hoisting coupling device with cooperation of multiple cranes and dynamic detection thereof. The hoisting coupling device comprises an upper machine, a lower machine and three groups of coupling supports with the same structure. Each group of coupling support comprises a truss, and truss supporting plates arranged at two ends of the truss. A main hydraulic cylinder is arranged in the middle position of each truss supporting plate. four same sub-hydraulic cylinders are uniformly distributed around the main hydraulic cylinder. The bar heads of the main hydraulic cylinder and the sub-hydraulic cylinders are coupled with ring flanges through pherical hinges. The bar tails of the main hydraulic cylinder and the sub-hydraulic cylinders are coupled with ring flanges through pherical hinges. The ring flanges are fixed on a frame fixation plate through bolts. The frame fixation plate is connected with a chassis of a crane through bolts. Four pairs of rings are uniformly distributed in the truss supporting plates and the frame fixation plate. A tensioning wire rope is connected between each pair of rings. The hoisting coupling device has advantages of simple structure, stable coupling, reliable performances, strong bearing capability, strong adaptability and modularization, and can achieve rapid dismounting and installation.

Description

technical field [0001] The invention relates to a multi-crane cooperative hoisting device and its dynamic detection, in particular to a multi-crane cooperative hoisting connection device and a detection method. Background technique [0002] Lifting equipment is an important tool for factories, railways, ports and other departments to realize the mechanization of material handling. In recent years, with the rapid development of the manufacturing industry, heavy and large-scale loads and increasingly complex hoisting environments have put forward higher requirements for hoisting equipment and hoisting technology. Restricted by coordination ability and load capacity, a single lifting device can no longer fully meet the current requirements. Multi-crane cooperative hoisting has the advantages of strong load capacity, stable hoisting process, and high cost performance. been more and more applied. [0003] Multiple cranes jointly lift an object, which means that the complexity, ...

Problems solved by technology

However, at this stage, in the process of multi-crane cooperative hoisting, manual control is generally used, which relies too much on the operator's operating experience, and the phenomenon of multi-machine asynchrony is inevitable

Since multiple cranes are coupled together through heavy objects, asynchronous control can easily cause the sway of the heavy objects and the inclinatio
