An intelligent detection device for the height of slab clamps

Abstract

The invention discloses plate blank clamp height intelligent detection equipment which comprises a measurement module, a correction limit, a decoding module, a CPU (Central Processing Unit) module, an SPC3 (Siemens Profibus Controller 3) module and a DP (Data Processing) interface module. The plate blank clamp height intelligent detection equipment is characterized in that the measurement module is connected with the decoding module; the decoding module and the correction limit are connected with the CPU module; the CPU module is connected with the SPC3 module; the SPC3 module is connected with the DP interface module; the correction limit is a rotary cam limit; and the cam limit is in mechanical connection with an encoder through a reduction gear unit. The measurement module acts as a height detection sensor, data is transmitted to a CPU through the decoding module, then the CPU transmits the data to a DP bus wire through an SPC3 chip and a DP interface circuit, so as to accomplish communication with a PLC (Programmable Logic Controller) on the DP bus wire; height detection is realized by the measurement module; data decoding of the measurement module is realized by the decoding module; data acquisition is realized by the CPU module; receiving and transmitting of Profibus data are accomplished by the SPC3 module, and access between the CPU and Profibus is realized; electrical connection between the Profibus and the plate blank clamp height intelligent detection equipment is realized by the DP interface module; and the DP interface module has electrical isolation function.

Description

technical field [0001] This patent belongs to the technical field of automation control, and relates to an intelligent detection device for the height of slab tongs. Background technique [0002] In iron and steel enterprises hot rolling, cold rolling, continuous casting and other factories, cranes are mainly used to carry slabs, and cranes also rely on slab tongs to carry slabs. In order to improve work efficiency, it is usually necessary to carry multiple slabs at a time, and to carry different numbers of slabs, the jaws of the slab tongs need to be raised and lowered to different heights. Most tongs on the market currently use the driver's visual inspection method to clamp The height control of the tongs, the accuracy is not guaranteed, and safety accidents are prone to occur. A small number of clamps will use limit switches to indicate the lifting height of the clamps. Install limit switches at different slab positions. This method will be more reliable than manual visu...

Problems solved by technology

However, it has basically been working for about 20 years now, and most of them have been damaged. Some of the equipment in use also has problems of reduced accuracy and reduced stability.

In the current form of vigorously promoting automated driving, the current height detection equipment can no longer meet the requirements, so it is urgent to adopt a new type of reliable and stable height detection equipment to meet the needs of crane automation transformation
