Problems solved by technology

But for wide and thick plates, dozens of lifting units are required to work together instead of a simple combination of a bunch of electromagnets, which brings a series of special problems to the design of the electromagnetic lifting system, such as the rationality of the layout of the electromagnets , the selection and cooperative work of groups of electromagnets need to meet the magnetic adjustment of different suspended objects, system safety protection and fault diagnosis, etc.

Embodiment Construction

[0011] As shown in the figure, the present invention includes a main control unit, a transformer, a rectifier, and a contactor. The rectifier and the contactor are respectively connected to the main control unit; the rectifier is connected to the power supply through the transformer.

[0012] The main control unit adopts PLC.

[0013] The invention also includes a battery, which is connected to the contactor through the battery control circuit.

[0014] Such as figure 1 Shown. The main electronic control circuit is composed of a PLC main control unit, a transformer, a controllable rectifier module and a contactor. The PLC main control unit realizes the electromagnet adjustment by controlling the controllable rectifier module, and the power on and off selection of each suction cup is realized by the PLC control contactor. These main circuits constitute the magnetic modulation and magnetic retention control panel and the automatic charging screen. Together with the maintenance-fr...

Abstract

The invention discloses an electromagnetic hoisting system for a wide and thick steel plate, which relates to a structure improvement of an electromagnetic hoisting system for a wide and thick steel plate, and is accurate and stable in running. The electromagnetic hoisting system comprises a main control unit, a transformer, a rectifier and a contactor, and is structurally characterized in that the rectifier and the contactor are respectively connected with the main control unit, and the rectifier is connected with a power supply through the transformer.

Description

technical field [0001] The invention relates to the improvement of the structure of a wide and thick steel plate electromagnetic lifting system. Background technique [0002] Wide and thick steel plates play an extremely important role in the national economy and national defense construction; however, our country is still in its infancy in the research and application of wide and thick plate lifting technology. Wide and thick plates are characterized by being large and heavy. For example, a steel plate with an overall size of 13000mmx4900mmx50mm weighs 25t. For general steel lifting, one or several electromagnets are usually used for lifting. But for wide and thick plates, dozens of lifting units are required to work together instead of a simple combination of a bunch of electromagnets, which brings a series of special problems to the design of the electromagnetic lifting system, such as the rationality of the layout of the electromagnets , the selection and cooperative ...
