Abstract
The invention provides a control device and a control method for safe lifting of a dummy bar of a continuous casting machine. The control device for safe lifting of the dummy bar of the continuous casting machine comprises the dummy bar driven by transmission rollers and a lifting hook driven by a lifting transmission device, wherein the lifting transmission device drives a continuous casting machine PLC (programmable logic controller) connected with the transmission rollers; the control device is characterized in that a vertical through hole is formed in the dummy bar, a photoelectric detector is arranged at the lower part of the dummy bar, the photoelectric detector is mounted in such a position that the photoelectric detector is aligned to the vertical through hole when the lifting hook is aligned to a lifting hole of the dummy bar, and the photoelectric detector is connected with the continuous casting machine PLC. With the adoption of the control device and the control method, the lifting hook and the dummy bar can be matched precisely during lifting of the dummy bar, and safe lifting of the dummy bar is guaranteed.
Description
technical field:
The present invention relates to a kind of dummy bar of continuous casting machine security improvement control device and control method, belong to control technology field, steel smelting-continuous casting field.
background technology:
In steel production enterprise, slab caster more commonly adopts dress dummy bar mode, and object to shorten the time thus raising casting machine production efficiency of casting and preparing.For realizing guiding the dummy bar of strand to rise on continuous casting platform in streamline fan-shaped section, the security improvement of relevant equipment for dummy bar must be set.Under casting mode dummy bar guide strand from fan-shaped section out after, the elevator hook of transferring in advance is in the duty waiting for dummy bar, reach after on above hoist hook position how to start elevator hook functionally in time at dummy bar tail end, conditional request is very harsh, is pressed for time, apart from short.Otherwise promote failure or occur device security accident,
Meanwhile, possess safe and reliable to initial and the requirement of process hoisting velocity, prevent equipment collision, falling accident generation, be recycled on dummy bar car until rising position of rest is waited for, in order to next use.
Summary of the invention
The object of the invention is to provide a kind of dummy bar of continuous casting machine security improvement control device and control method for above-mentioned Problems existing, make when dummy bar promotes hoist hook and dummy bar precisely coordinate, ensure dummy bar security improvement.
Above-mentioned object is achieved through the following technical solutions:
Dummy bar of continuous casting machine security improvement control device, comprise the dummy bar driven by live-roller and the hoist hook driven by lifting gear, described lifting gear drives and is connected conticaster PLC with described live-roller, described dummy bar has vertical through hole, described dummy bar bottom is provided with photoelectric detector, described photoelectric detector installation site is when hoist hook aims at the position of the lifting hole of dummy bar, vertical through hole described in photoelectric detector aligning, the PLC of casting machine in succession described in described photoelectric detector connects.
Described dummy bar of continuous casting machine security improvement control device, described live-roller installs encoder, the conticaster PLC described in described encoder connects.
Described dummy bar of continuous casting machine security improvement control device, described lifting gear adopts hoist engine.
The method of dummy bar of continuous casting machine security improvement control is carried out with above-mentioned dummy bar of continuous casting machine security improvement control device, the method is: under the driving of live-roller, dummy bar guides strand to move, when the afterbody of dummy bar moves to above photoelectric detector, photoelectric detector is blocked by dummy bar, the detection signal of photoelectric detector is by 1 to 0, along with the continuation of dummy bar is moved, when the vertical through hole on dummy bar moves to directly over photoelectric detector, when the detection signal of photoelectric detector meets by 0 to 1, namely trigger a dummy bar and promote enabling signal, dummy bar promotes enabling signal and sends to lifting gear, lifting gear upwards starts, and run up with a pre-set value Vg until hoist hook reliably hook mobile in dummy bar afterbody after the speed of lifting gear be switched to the speed V of strand movement by Vg, until the head of dummy bar and strand depart from.
The method that described dummy bar of continuous casting machine security improvement controls, the speed V of described strand movement is by the encoder Real-Time Monitoring be arranged on live-roller and send to conticaster PLC.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, live-roller; 2, dummy bar; 3, lifting gear; 4, hoist hook; 5, conticaster PLC; 6, vertical through hole; 7, photoelectric detector; 8, lifting hole; 9, encoder.
Detailed description of the invention
Dummy bar of continuous casting machine security improvement control device as shown in Figure 1, comprise the dummy bar 2 driven by live-roller 1 and the hoist hook 4 driven by lifting gear 3, described lifting gear drives and is connected conticaster PLC5 with described live-roller, described dummy bar has vertical through hole 6, described dummy bar bottom is provided with photoelectric detector 7, described photoelectric detector installation site is when hoist hook aims at the position of the lifting hole 8 of dummy bar, vertical through hole described in photoelectric detector aligning, the PLC of casting machine in succession described in described photoelectric detector connects.
Described dummy bar of continuous casting machine security improvement control device, described live-roller is installed encoder 9, the conticaster PLC described in described encoder connects.
Described dummy bar of continuous casting machine security improvement control device, described lifting gear adopts hoist engine.
The method of dummy bar of continuous casting machine security improvement control is carried out with above-mentioned dummy bar of continuous casting machine security improvement control device, the method is: under the driving of live-roller, dummy bar guides strand to move, when the afterbody of dummy bar moves to above photoelectric detector, photoelectric detector is blocked by dummy bar, the detection signal of photoelectric detector is by 1 to 0, along with the continuation of dummy bar is moved, when the vertical through hole on dummy bar moves to directly over photoelectric detector, when the detection signal of photoelectric detector meets by 0 to 1, namely trigger a dummy bar and promote enabling signal, dummy bar promotes enabling signal and sends to lifting gear, lifting gear upwards starts, and run up with a pre-set value Vg until hoist hook reliably hook mobile in dummy bar afterbody after the speed of lifting gear be switched to the speed V of strand movement by Vg, until the head of dummy bar and strand depart from.Hoist hook drop in advance be positioned at dummy bar movement horizontal plane below have some distances, therefore hoist hook run up within several seconds, can be convenient to reliably to hook mobile in dummy bar afterbody.After the head of dummy bar and strand have departed from, the speed of hoist hook and dummy bar has transferred to synchronously, and final arrival promotes position of rest, and dummy bar enhanced feature terminates.
The method that described dummy bar of continuous casting machine security improvement controls, the speed V of described strand movement is by the encoder Real-Time Monitoring be arranged on live-roller and send to conticaster PLC.
The present invention makes hoist hook and dummy bar precisely coordinate when dummy bar promotes, ensure dummy bar security improvement.By scene chronically use certificate understand that the design of this device is the scene reality that suits conticaster, i.e. safety but also reliable, and the relevant device of type of industry can be promoted the use of.
