Abstract
The utility model discloses a checkout gear for monitoring the online running state of a fan-shaped section driven roller of a straight curved spray continuous casting machine, and aims to solve the problems existing at present that when the driven roller is lifted upwards to run, once a depressive pressure contact generates a fault or an error action, the lifting action stops at once, thereby causing the lifting position signal of the monitoring picture of the driven roller appeared in a computer is not consistent to the fact to cause a heavy accident, etc. The utility model provides a technical proposal for solving the problem that the checkout gear consists of the driven roller (1), the computer (2), a PLC controller (3) connected with the computer, a valve platform (4), an electromagnetic valve (5) connected on the valve platform (4), a pressure oil pipe (6) connected with the electromagnetic valve (5) and an oil cylinder (9). The utility model is characterized in that a pressure relay (8) is connected between each driven roller (1) and the PLC controller (3) through a signal wire (7), and the pressure relay (8) is connected to and communicated with the pressure oil pipe (6). The utility model can efficiently monitor the condition of the in-place signal of the lifting and the pressing actions of the fan-shaped section driven roller, the monitored result is easy to be found and treated in time, the work intensity is reduced, and the operation and the maintenance are simple and convenient.
Description
Technical field
The utility model relates to checkout gear, specifically more belongs to the on-line measuring device of straight arc continuous casting machine fan-shaped segment driven roller.
Background technology
The remarkable action of continuous casting machine fan-shaped segment driven roller will cause extremely serious consequence: as opening the driven roller that ought to lift when watering if do not lift and will break driven roller and cold base can't be pulled out from fan-shaped section, cause casting machine to be shut down, influence is produced.At present, straight arc continuous casting machine fan-shaped segment driven roller lifts, depresses the signal that puts in place of action, owing to be to rely on collection to depress the directional pressure contact to carry out programme controlled.Its deficiency is a part: when driven roller upwards lifts operation, in case the press contact of depressing breaks down or misoperation, lifting action can stop immediately, the driven roller monitored picture that causes computer to occur lifts that a signal does not conform to the actual conditions, the phenomenon of remarkable action, to cause a serious accident as after not in time not finding fault, open to water.
The utility model content
The utility model is in order to overcome the deficiency of above-mentioned existence, provide a kind of and can effectively detect the situation that control fan-shaped section driven roller lifted, depressed the signal that puts in place of action, avoid accident to produce, Jian Kong result is easy to observe simultaneously, is convenient to the on-line measuring device that the attendant in time finds the straight arc continuous casting machine fan-shaped segment driven roller handled.
The technical measures that address the above problem:
Straight arc continuous casting machine fan-shaped segment driven roller on-line measuring device, mainly by driven roller, computer, the PLC controller that is connected with computer, valve platform, be connected the magnetic valve on the valve platform, the pressure oil pipe that is connected with magnetic valve, oil cylinder and form.In order effectively to detect the situation that control fan-shaped section driven roller lifted, depressed the signal that puts in place of action, avoid accident to produce, and help monitored results and observe, the attendant is in time found and handle it, it is: be connected pressure switch by holding wire between each driven roller and PLC controller, pressure switch is connected in pressure oil pipe and communicates.
It is: the installation number of pressure switch is 2: 1 with the number of magnetic valve also.
Of the present utility model have can effectively detect the situation that control fan-shaped section driven roller lifted, depressed the signal that puts in place of action, avoid accident to produce, characteristics such as Jian Kong result is easy to observe simultaneously, is convenient to the attendant and in time finds and handle, and labour intensity reduces, Operation and Maintenance is simple and convenient.
Description of drawings
Fig. 1 is a straight arc continuous casting machine fan-shaped segment driven roller on-line measuring device structural representation
The specific embodiment
Be described in further detail below in conjunction with accompanying drawing:
Straight arc continuous casting machine fan-shaped segment driven roller on-line measuring device, mainly by driven roller (1), computer (2), the PLC controller (3) that is connected with computer (2), valve platform (4), be connected the magnetic valve (5) on the valve platform (4), the pressure oil pipe (6) that is connected with magnetic valve (5) is formed.Getting driven roller (1) is 14, (5) 14 of magnetic valves, and relevant pressure relay (8) is installed 28; Between the corresponding contact of each driven roller (1) and PLC controller (3), connect a pressure switch (8) by holding wire (7); Each pressure switch (8) is connected on the pressure oil pipe (6) and communicates.
Operation principle:
Main oil pipe pressure is 20Mpa.The checkout gear effect can detect lifting of oil cylinder and depress action:
When lifting action, magnetic valve (5) Electrical heads gets, pressure oil is by the cavity of resorption of magnetic valve (5) to oil cylinder (9), the pressure switch (8-b) that be connected with pressure oil pipe (6) this moment reaches setting pressure, issue a signal to PLC controller (3) and confirm that to lifting action computer (2) the picture prompting then can not occur and report to the police; If when driven roller (1) lifts when not in place, pressure switch (8-b) can't reach setting pressure, does not promptly issue a signal to PLC controller (3), and the picture of warning message will appear in computer (2), and alert is in time handled.
When depressing action, magnetic valve (5) Electrical heads must not, pressure oil is directly by the epicoele of magnetic valve (5) to oil cylinder (9), the pressure switch (8-a) that be connected with pressure oil pipe (6) this moment reaches setting pressure, issue a signal to PLC controller (3) and confirm that to depressing action computer (2) the picture prompting then can not occur and report to the police; If depress when not in place when driven roller (1), pressure switch (8-a) can't reach setting pressure, does not promptly issue a signal to PLC controller (3), and the picture of warning message will appear in computer (2), and alert is in time handled.
Realized that by above method the monitoring of the operation conditions by pressure switch (8) and magnetic valve (5) realizes the supervision control to driven roller (1), assurance ordinary production.
Claims (2)
1. straight arc continuous casting machine fan-shaped segment driven roller on-line measuring device, mainly by driven roller (1), computer (2), the PLC controller (3) that is connected with computer (2), valve platform (4), be connected the magnetic valve (5) on the valve platform (4), the pressure oil pipe (6) that is connected with magnetic valve (5), oil cylinder (9) and form, it is characterized in that: be connected pressure switch (8) by holding wire (7) between each driven roller (1) and PLC controller (3), pressure switch (8) is connected in pressure oil pipe (6) and communicates.
2. straight arc continuous casting machine fan-shaped segment driven roller on-line measuring device as claimed in claim 1 is characterized in that: the installation number of pressure switch (8) is 2: 1 with the number of magnetic valve (5) also.
