Abstract
The invention relates to the technical field of metallurgy safety, and particularly discloses an automatic locking system for preventing an oxygen lance from falling down. The automatic locking system comprises an oxygen lance speed sensor arranged on an oxygen lance lifting steel wire roller. The automatic locking system is characterized in that the oxygen lance speed sensor is connected with a speed signal receiving and processing device; the speed signal receiving and processing device is connected with a speed signal converting and transmitting device; the speed signal converting and transmitting device and an industrial personal computer are connected with each other through a data communication device; and the speed signal converting and transmitting device is connected with an oxygen lance speed locking device. The automatic locking system independently runs beside a PLC and converter control system and can rapidly prevent oxygen lance falling accidents in time when the PLC and converter control system loses efficacy, and therefore safety is enhanced for oxygen lance operation, and accidents are reduced.
Description
(1) technical field
The present invention relates to metallurgical security technical field, particularly a kind of oxygen rifle automatic locking system that falls.
(2) background technology
At present, steel-making mostly adopts converter mode to make steel, and carries out in converter by oxygen rifle with the mode of oxygen, and oxygen rifle is by PLC Controlling System control lifting.Oxygen rifle is operated in hot environment, and the inner water quench of passing through, will likely blast once oxygen rifle is fallen in molten steel, cause serious accident, therefore, control safely and reliably oxygen rifle just most important.
There is various heavy current installations and weak current equipment in steel-making scene, due to cross wiring and the distribution of various device, the existence of various interference is just unavoidable.Oxygen rifle mostly adopts PLC and Frequency Converter Control at present, once PLC is interfered or frequency transformer loses moment, oxygen rifle just may be out of hand and fall into the accident of molten steel.It is out of hand and fall into the situation of molten steel to have there is repeatedly oxygen rifle in current multiple factory.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of reasonable in design, the oxygen rifle that effectively the ensures production safety automatic locking system that falls.
The present invention is achieved through the following technical solutions:
A kind of oxygen rifle automatic locking system that falls, comprise the oxygen rifle velocity sensor being arranged on oxygen lance lifting wire rope drum, it is characterized in that: described oxygen rifle velocity sensor connection speed signal receiving and processing device, speed signal receiving and processing device connection speed signal converting transmission device, speed signal converting transmission device interconnects by data communication apparatus and industrial computer, and speed signal converting transmission device connects oxygen rifle speed locking device.
Oxygen rifle velocity sensor of the present invention detects the rising or falling speed of oxygen rifle by detecting the rotation of cylinder, industrial computer records the real time execution speed and the history curve that show oxygen rifle, in the time of hypervelocity, sends instructions to carry out the locking of oxygen rifle by industrial computer.
Described oxygen rifle speed locking device, by oxygen rifle band brake apparatus control oxygen rifle, is realized the timely quick lock in of oxygen rifle.
Described industrial computer connects indicating meter, demonstrates intuitively the real-time detected status of oxygen rifle speed by indicating meter.
Detect rising and the lowering speed of oxygen rifle by oxygen rifle velocity sensor, receive the also real-time speed of processes and displays oxygen rifle by speed signal receiving and processing device, then send through speed signal converting transmission device the real-time speed that industrial computer processing and control element (PCE) shows and record oxygen rifle to, in the time that exceeding the speed of normal setting, discovery oxygen rifle speed sends oxygen supply rifle speed locking device by data communication apparatus, by oxygen rifle speed locking device control band-type brake positive lock oxygen rifle, anti-block rifle falls into molten steel.
Independent operating of the present invention is outside PLC and frequency converter control system, and the generation of timely anti-block rifle falling accident fast in the time that PLC and frequency convertor system occur to lose efficacy, strengthens the operational safety of oxygen rifle, and minimizing accident occurs.
(4) brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is syndeton schematic diagram of the present invention.
In figure, 1 oxygen rifle velocity sensor, 2 speed signal receiving and processing devices, 3 speed signal converting transmission devices, 4 data communication apparatus, 5 industrial computer, 6 oxygen rifle speed locking devices, 7 indicating meters.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises the oxygen rifle velocity sensor 1 being arranged on oxygen lance lifting wire rope drum, described oxygen rifle velocity sensor 1 connection speed signal receiving and processing device 2, speed signal receiving and processing device 2 connection speed signal converting transmission devices 3, speed signal converting transmission device 3 interconnects by data communication apparatus 4 and industrial computer 5, and speed signal converting transmission device 3 connects oxygen rifle speed locking device 6; Described industrial computer 5 connects indicating meter 7.
Oxygen rifle velocity sensor 1 is arranged on oxygen lance lifting wire rope drum, and oxygen rifle velocity sensor 1 detects the rotational angle speed of cylinder, and velocity of rotation is converted to SSI signal sends speed signal receiving and processing device 2 to; Speed signal receiving and processing device 2 is converted to the rotational angle speed signal receiving rising and the lowering speed (being the rise and fall speed of oxygen rifle) of cylinder wireline; The oxygen rifle speed signal that speed signal converting transmission device 3 sends speed signal receiving and processing device 2 is converted to RS485 signal and sends industrial computer 5 to; Industrial computer 5 receives oxygen rifle speed signal by data communication apparatus 4 and shows and record, when oxygen rifle speed exceedes after the permissible value of setting, sends out lock rifle order oxygen supply rifle speed locking device 6; Oxygen rifle speed locking device 6 is received after the order of lock rifle, controls oxygen rifle band brake apparatus locking oxygen rifle, prevents from falling.
