Abstract

The invention provides a four-rope grab bucket slag material grabbing system which comprises a computer, a PLC, a lifting frequency converter, an incremental encoder A, an opening-closing frequency converter, an incremental encoder B, a cart and trolley positioning device, a twisted rope detecting device, an overload limiter, a cart walking motor, a trolley walking motor, a runway girder, a travelling crane trolley and a grab bucket, wherein the travelling crane trolley is in sliding fit with the runway girder; the computer, the lifting frequency converter, the opening-closing frequency converter, the cart and trolley positioning device, the twisted rope detecting device, the overload limiter, the cart walking motor and the trolley walking motor are connected with the PLC separately; and the PLC and the computer realize data exchange through the wired or wireless communication manner. Compared with the existing manual operation, the four-rope grab bucket slag material grabbing system can still carry out safe operation on the condition that heavy fog or water vapor affects the sight line to reduce potential safety hazard and prevents a worker from operation under sulfur-containing water vapor to reduce health hazard.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a system and method for grabbing slag with a four-rope grab bucket. Background technique [0002] At present, the driving of the four-rope grab is controlled manually. The mechanical part includes the travel reducer for large and small vehicles, the lifting drum and reducer, the opening and closing drum and the reducer, and the electrical control part consists of contactors, stator resistors, travel motors, and hoisting motors. , Overload limiter, limit cam and door limit. The water vapor in the blast furnace slag pool is relatively large, which seriously affects the line of sight in winter, and people are prone to safety accidents when they work high-intensity in harsh environments. [0003] With the development of economy and technology, automation equipment is used more and more widely in industrial production. How to complete some automation projects that require positioning...
