The invention discloses a method for protecting a horizontal magnetic filter walking device, which comprises the following steps: a proximity switch used for touching a limit push rod pushed by a magnetic bar to reciprocate is arranged on the horizontal magnetic filter walking device, the proximity switch is connected with a control unit used for automatically controlling the magnetic filter, and the control unit sets the induction period of the proximity switch; the control unit controls the horizontal magnetic filter walking device to start to operate, the control unit periodically acquires a signal that the limit push rod touches the proximity switch according to the set induction period parameters, when the limit push rod touches the proximity switch in the period time, the proximity switch feeds back the signal to the control unit, and the control unit controls the horizontal magnetic filter walking device to normally operate; otherwise, the machine is stopped. The invention can solve the problems that the existing horizontal magnetic filter walking device has high failure rate and influences the production progress.
Description
Technical Field
The invention relates to the technical field of steel equipment accessory manufacturing, in particular to a method for protecting and monitoring a horizontal magnetic filter walking device.
Background
The main function of the emulsion in the production process of the cold continuous rolling strip steel is to lubricate the surface of the strip steel and cool a roller, and meanwhile, the quality of an emulsion system also directly influences the plate shape effect of the rolled strip steel and the surface cleanliness of the strip steel. In the production process, the emulsion brings iron powder generated by rolling the strip steel into the emulsion box, and the iron powder in the emulsion is removed through the magnetic filter. The walking device for scraping the oil sludge on the magnetic rod by the magnetic filter comprises a limit push rod 2 which is pushed to move back and forth when the magnetic rod 1 passes through the walking device, and as shown in figure 1, the back and forth movement of the limit push rod and the operation of the magnetic rod are periodic because the magnetic rod is periodically conveyed. Because the device of magnetic filter does not have running state monitoring protection device, the drive arrangement of running gear and bar magnet drives different sprocket drives by same motor, if running gear's chain breaks down, and the bar magnet removes the chain and continues to keep moving, can lead to being equipped with the push rod card of scraping the harrow on the running gear on the bar magnet, cause the bar magnet to buckle in batches and warp even, hold the risk of breaking bar magnet and running gear, seriously endanger stable operation.
Disclosure of Invention
The invention aims to solve the problem that the conventional horizontal magnetic filter walking device is high in failure rate and affects the production progress.
In order to solve the problems, the technical scheme of the invention is as follows: the method for protecting the horizontal magnetic filter walking device comprises the following steps:
A. the horizontal magnetic filter walking device is provided with a proximity switch which is used for touching a limit push rod pushed by a magnetic rod to do reciprocating motion, the proximity switch is connected with a control unit which is used for automatically controlling the magnetic filter, the control unit sets an induction period of the proximity switch, the induction period is the reciprocating period of the limit push rod, and the horizontal magnetic filter walking device is initialized;
B. the control unit controls the horizontal magnetic filter walking device to start running, the control unit periodically acquires a signal that the limit push rod touches the proximity switch according to the set induction period parameters,
when the limit push rod touches the proximity switch in a periodic time, the proximity switch feeds back a signal to the control unit, and the control unit controls the horizontal magnetic filter walking device to normally run;
when the limit push rod does not touch the proximity switch in the period time, the proximity switch does not feed back a signal to the control unit in the induction period, and the control unit controls the horizontal magnetic filter walking device to stop running.
In the above technical solution, a more specific solution may be: the control unit counts down through a clock timer, the clock timer of the control unit resets time once and counts down again when the control unit receives a signal once, and the control unit controls the horizontal magnetic filter walking device to stop when the count down reaches 0.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
according to the protection method for the horizontal magnetic filter walking device, the proximity switch used for touching the limit push rod pushed by the magnetic rod to move back and forth is arranged on the horizontal magnetic filter walking device, the proximity switch is connected with the control unit used for automatic control of the magnetic filter, an induction period is set, when the magnetic rod is clamped, the limit push rod cannot touch the proximity switch in time, the proximity switch cannot transmit signals to the control unit in the period, the control unit judges that the magnetic rod has a fault and controls shutdown, the problem that the magnetic rod is damaged or blocked can be effectively avoided, and the safety stability of the operation of the magnetic filter is guaranteed. The operator can see the alarm of the interruption of the equipment operation on the picture of the operation room, and the operator can inform the relevant personnel of the treatment in time, thereby reducing the labor intensity.
