Description

Technical Field

[0001] The invention relates to a method for preventing position deviation, in particular to a method for preventing lateral position deviation, and belongs to the technical field of steel plate transportation in the metallurgical industry. Background Art

[0002] The competition in the steel industry is becoming increasingly fierce. In the domestic market, there are a large number of steel companies, and the problem of overcapacity still exists. This puts steel companies under tremendous pressure in competing for market share, reducing costs, and improving product quality. Therefore, the quality link is particularly important. The steel plate transverse moving device is a mechanical device that can achieve fast and accurate transverse movement of steel plates in production lines or other working areas. The steel plate transverse moving device not only improves work efficiency and reduces labor costs, but also significantly improves the safety and reliability of the production process. Therefore, the accuracy requirements of the device must be guaranteed. In the event of position deviation, it will cause a series of problems, equipment damage, steel plate defects, etc.

[0003] At present, patent CN101736699B is a method for accurately positioning the sliding of a steel box girder with a full support. This method is a method for accurately positioning and installing a steel box girder with simple procedures and convenient operation, and can shorten the construction period and reduce capital and equipment investment. However, it detects its own position and cannot detect foreign objects; CN101736699B is a control method for a heating furnace hot delivery transverse steel pusher based on dynamic correction. This control method for a heating furnace hot delivery transverse steel pusher based on dynamic correction can quickly, accurately, and in real time simply control the synchronous driving of two transverse steel pushers to prevent the hot delivery transverse steel pusher from being affected by factors such as signal delay coefficient, oil circuit pressure difference, and different friction coefficient of the motion mechanism, which may cause the billet to tilt or even get stuck. It can effectively improve the hot delivery rate of the heating furnace, greatly reduce energy consumption, and shorten the production cycle; but it adopts proximity switch detection, the measurement accuracy is not high, and multiple detections are required, which is inconvenient to use.

[0004] Therefore, in this case, developing a method for preventing lateral position deviation while maintaining the accuracy of the equipment while improving production and efficiency has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a method for preventing lateral position deviation, which is simple and easy to implement, effectively prevents equipment position deviation and ensures the quality of steel plates.

[0006] In order to solve the above technical problems, the present invention provides a method for preventing lateral position deviation, which specifically comprises the following steps: (1) The detection components are fixedly arranged on the transverse panel of the steel plate transverse device; (2) The steel plate moves on the transverse movement device, and the detection components on the transverse movement panel measure the distance of the steel plate to detect whether the transverse movement of the steel plate is in place; (3) When the detection component detects the steel plate, there is an output signal, the transverse movement is in place, the encoder value in the transverse movement device is normal, and the steel plate moves normally transversely; when the detection component does not detect the steel plate, there is no signal output, the transverse movement is not in place, the encoder value in the transverse movement device is modified to normal, and the steel plate position deviation is processed as an alarm.

[0007] The technical solution further defined in the present invention is: Furthermore, in the aforementioned method for preventing lateral position deviation, the detection component is located at the exit of the steel plate lateral movement device.

[0008] The technical effect is that at a specific position at the exit, it is necessary to ensure that the detected object leaves the lateral movement range before the lateral movement can be moved, which is more accurate.

[0009] In the aforementioned method for preventing lateral position deviation, the detection element is a laser detector.

[0010] In the aforementioned method for preventing lateral position deviation, the detection component is connected to and controlled by a set PLC control system.

[0011] The aforementioned method for preventing lateral position deviation also includes a display screen, and the PLC control system is connected to the display screen to display data.

[0012] The beneficial effects of the present invention are: The present invention adopts a laser detector with better accuracy. It only needs to detect the distance of the steel plate to determine whether it has deviation. It is more convenient to use and has faster detection. It can effectively ensure the accuracy of the transverse movement equipment and prevent the equipment position from deviating, causing steel plate quality and equipment accidents.

[0013] The present invention increases hard limit detection, detects components, ensures the accuracy of the equipment, and can avoid equipment failure caused by equipment position error, resulting in downtime.

[0014] The present invention improves the accuracy of the equipment position, and while protecting the normal operation of the on-site equipment, can effectively avoid the collision of the steel plate during operation, causing quality accidents and unplanned accidents.
