Description

Technical Field

[0001] This invention relates to the field of steel rolling control technology, and in particular to a control method, device, and electronic equipment for a belt winding aid. Background Technology

[0002] like Figure 1 As shown, the belt winding aid 40 consists of a winding aid belt 60, a winding aid flap 30, a winding aid flap guide plate 20, and some mechanical and hydraulic structures. It is mainly used to assist the coiler in winding the straight strip steel 70 into a strip steel coil. The threading guide plate 80 is mainly used to assist the straight strip steel head in threading onto the coiler core shaft 50. The front end of the rotating flap at the bottom of the belt winding aid 40 is connected to the winding aid flap guide plate 20. Therefore, the gap 10 between the belt winding aid flap guide plate 20 and the threading guide plate 80 is determined by the position of the rotating flap at the bottom of the belt winding aid 40 and the horizontal extension position of the threading guide plate 80.

[0003] In actual production, due to the slippage problem of the hydraulic cylinder body of the coiler flip plate, it is easy for the belt guide plate to come into contact with the coiler flip plate guide plate, the belt to be clamped between the two guide plates and unable to move, the belt head cannot move forward with the belt, resulting in the steel strip accumulating at the No. 1 steering roller, thus causing serious problems such as a stop and steel stacking accident. Summary of the Invention

[0004] This application provides a control method, device, and electronic device for a belt winding aid. By controlling the gap between the belt winding aid's flip plate guide and the belt threading guide before the automatic belt threading step is activated, the hydraulic cylinder of the belt winding aid's flip plate is prevented from slipping, which could lead to a shutdown and steel stacking accident due to an excessively low gap between the belt winding aid's flip plate guide and the belt threading guide.

[0005] In a first aspect, the present invention provides the following technical solution through an embodiment of the present invention:

[0006] A control method for a belt winding aid includes: during the operation of the strip, acquiring the distance between the strip head and the shearing position; if the distance is within a preset distance threshold, acquiring the positional deviation between the hydraulic cylinder engagement position and a preset target position, wherein the hydraulic cylinder is located at the bottom rotating flap of the belt winding aid; if the positional deviation is greater than a preset first deviation threshold, compensating for the hydraulic cylinder engagement position to control the gap between the flap guide plate and the belt threading guide plate of the belt winding aid.

[0007] Preferably, if the distance is not within a preset distance threshold, the positional deviation between the hydraulic cylinder deployment position and the preset target position is obtained; if the positional deviation is greater than a preset second deviation threshold, the hydraulic cylinder deployment position is compensated so that the positional deviation between the compensated hydraulic cylinder deployment position and the preset target position is within a preset error range, wherein the second deviation threshold is greater than the first deviation threshold.

[0008] Preferably, before obtaining the positional deviation between the hydraulic cylinder deployment position and the preset target position when the distance is within a preset distance threshold, the method further includes: adjusting the preset second deviation threshold to a preset first deviation threshold; and after compensating the hydraulic cylinder deployment position when the positional deviation is greater than the preset first deviation threshold, the method further includes: if the positional deviation between the hydraulic cylinder deployment position and the preset target position is detected to be within a preset error range, then correcting the preset first deviation threshold to the preset second deviation threshold.

[0009] Preferably, the preset distance threshold is between 5 and 15 mm.

[0010] Preferably, the preset first deviation threshold is between 0.5 and 0.8 mm.

[0011] Preferably, the preset second deviation threshold is 1.2 mm.

[0012] Preferably, the compensation for the engagement position of the hydraulic cylinder includes: controlling the hydraulic cylinder body shut-off valve to open and the proportional valve to output, thereby compensating for the engagement position of the hydraulic cylinder.

[0013] Secondly, through an embodiment of the present invention, the present invention provides the following technical solution:

[0014] A control device for a belt winder, comprising:

[0015] The distance module is used to obtain the distance between the strip head and the shearing position during strip operation;

[0016] The position deviation module is used to obtain the position deviation between the hydraulic cylinder deployment position and the preset target position if the distance is within a preset distance threshold, wherein the hydraulic cylinder is located at the bottom rotating flap of the belt winder.

[0017] The compensation module is used to compensate for the hydraulic cylinder's engagement position if the position deviation is greater than a preset first deviation threshold, so as to control the gap between the belt winding aid flip plate guide and the belt threading guide.

[0018] Thirdly, through one embodiment of the present invention, the following technical solution is provided:

[0019] An electronic device includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of the method described in any of the first aspects above.

[0020] Fourthly, through one embodiment of the present invention, the following technical solution is provided:

[0021] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method described in any of the first aspects above.

[0022] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0023] The control method for a belt winding aid provided in this invention obtains the distance between the strip head and the shearing position, determines whether the automatic belt threading step should be activated immediately based on the distance, and obtains the positional deviation between the hydraulic cylinder engagement position and the preset target position when the detected distance is within a preset distance threshold. The preset distance threshold reflects the activation time of the automatic belt threading step, and the hydraulic cylinder is located at the bottom rotating flap of the belt winding aid. If the positional deviation is greater than a preset first deviation threshold, it indicates that the hydraulic cylinder is slipping, and the hydraulic cylinder engagement position is compensated to control the gap between the belt winding aid flap guide plate and the belt threading guide plate before the automatic belt threading step is activated. Therefore, before the automatic threading step begins, an automatic compensation is performed based on the hydraulic cylinder position. This ensures that when the automatic threading step begins, the actual position of the hydraulic cylinder remains at the preset target position, preventing the automatic compensation from being reactivated. This avoids the problems of traditional technologies where the automatic threading process begins before the automatic compensation function is completed, or where the automatic compensation function is forcibly stopped during the automatic compensation process, leading to further cylinder slippage of the hydraulic cylinder of the belt winder flapper, resulting in an excessively low gap between the belt winder flapper guide plate and the threading guide plate, causing a shutdown and steel stacking accident. This control method greatly improves the reliability of continuous annealing operations. Attached Figure Description

[0028] Figure 4 This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0029] Due to the frequent malfunctions in the continuous rolling mill annealing area, the applicant discovered through research that before the automatic threading step started, when the actual position of the hydraulic cylinder body of the auxiliary coiler tilting plate slid from the set value of 380mm to 378.8mm, the system had just activated the automatic compensation program. The normal process is that the shut-off valve opens and the proportional valve outputs. However, after the automatic threading step started running, it interrupted the activated automatic compensation program, causing the hydraulic cylinder body of the auxiliary coiler tilting plate to slip out 3mm instantly, reaching an actual position of 396mm. This deviation from the set deviation of 380mm was too large, causing the belt auxiliary coiler tilting plate guide plate to contact the threading guide plate, resulting in the production line stopping.

[0030] In view of this, the present application provides a control method, device and electronic device for a belt winding aid, which controls the gap between the belt winding aid flip plate guide and the belt threading guide before the automatic belt threading step is activated, so as to avoid the hydraulic cylinder of the belt winding aid flip plate slipping, which would cause the gap between the belt winding aid flip plate guide and the belt threading guide to be too low and result in a steel pile-up accident.

[0031] The overall technical solution of this application embodiment is as follows:

[0032] A control method, device, and electronic device for a belt winding aid includes: acquiring the distance between the head of the belt and the shearing position during the running of the belt; if the distance is within a preset distance threshold, acquiring the positional deviation between the hydraulic cylinder engagement position and a preset target position, wherein the hydraulic cylinder is located at the bottom rotating flap of the belt winding aid; if the positional deviation is greater than a preset first deviation threshold, compensating for the hydraulic cylinder engagement position to control the gap between the flap guide plate and the belt threading guide plate of the belt winding aid.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Firstly, the embodiments of the present invention provide a control method for a belt winding aid, specifically, as follows: Figure 2 As shown, the method includes the following steps S101 to S103.

[0035] Step S101: During the strip's operation, obtain the distance between the strip head and the shearing position;

[0036] Step S102: If the distance is within a preset distance threshold, then obtain the positional deviation between the hydraulic cylinder deployment position and the preset target position, wherein the hydraulic cylinder is located at the bottom rotating flap of the belt winder.

[0037] Step S103: If the position deviation is greater than the preset first deviation threshold, the hydraulic cylinder is put into position to compensate for the gap between the belt winding aid flip plate guide and the belt threading guide.

[0038] To ensure that the gap between the belt winding aid's flip plate guide and the belt threading guide is within the required range, the positioning accuracy of the hydraulic cylinder of the bottom rotating flip plate of the belt winding aid needs to be strictly controlled. Generally speaking, the automatic position compensation function can achieve this. When the difference between the hydraulic cylinder's positioning position and the preset target position exceeds the allowable range, the automatic compensation function is triggered to reposition the hydraulic cylinder.

[0039] Assuming the preset target position of the hydraulic cylinder is 380mm, the automatic compensation principle for the hydraulic cylinder position at the bottom rotating flap of the belt winding aid can be as follows: The program sets the bottom rotating flap position to 380mm. After positioning, the actual engagement position of the hydraulic cylinder is 380mm ± 2mm. Due to varying degrees of cylinder slippage, when the hydraulic cylinder's engagement position is lower than 378.8mm (the program sets the automatic compensation deviation to 1.2mm), the automatic compensation function is activated. The hydraulic cylinder's shut-off valve opens, the proportional valve outputs, and the hydraulic cylinder returns to the 380mm ± 2mm position. When the automatic belt feeding step begins, the automatic position compensation step will automatically stop because the strip is about to enter the winding mode. In the winding mode, the belt winding aid flap on the winding machine must remain stationary.

[0040] In order to ensure that the automatic compensation procedure avoids the automatic tape-threading stepping procedure, this application performs one round of automatic compensation procedure before the automatic tape-threading stepping procedure starts, depending on the situation, to ensure that the actual position is at 380mm±2mm before the automatic tape-threading stepping procedure starts. After the automatic tape-threading stepping procedure starts, the automatic compensation procedure will not be activated again.

[0041] In the specific implementation process, to determine whether the automatic strip feeding step should be activated immediately, the distance between the strip head and the shearing position is acquired during strip movement. If the distance is within a preset distance threshold, the positional deviation between the hydraulic cylinder engagement position and the preset target position is acquired. It should be noted that the strip weld position is the head of the next coil of strip.

[0042] The preset distance threshold can be between 5 and 15 meters, preferably 10 meters. The position deviation can be between 0.5 and 0.8 mm, preferably 0.7 mm.

[0043] Specifically, when the distance between the strip head and the shearing position is less than or equal to 10 meters, a pulse signal can be emitted to monitor the positional deviation between the hydraulic cylinder's engagement position and the preset target position. If the positional deviation is greater than or equal to 0.7 mm, compensation is performed on the hydraulic cylinder's engagement position; if the positional deviation is less than 0.7 mm, no compensation is performed.

[0044] Specifically, the compensation for the hydraulic cylinder's engagement position includes: controlling the hydraulic cylinder's shut-off valve to open and the proportional valve to output, thereby compensating for the hydraulic cylinder's engagement position so that the positional deviation between the compensated hydraulic cylinder engagement position and the preset target position is within a preset error range.

[0045] Furthermore, if the distance is not within a preset distance threshold, the positional deviation between the hydraulic cylinder deployment position and the preset target position is obtained; if the positional deviation is greater than a preset second deviation threshold, the hydraulic cylinder deployment position is compensated so that the positional deviation between the compensated hydraulic cylinder deployment position and the preset target position is within a preset error range, wherein the second deviation threshold is greater than the first deviation threshold. Optionally, the second deviation threshold can be 1.2mm.

[0046] For example, when the distance between the strip head and the shearing position is greater than 10 meters, the positional deviation between the hydraulic cylinder engagement position and the preset target position is obtained. If the positional deviation is greater than 1.2 mm, the hydraulic cylinder engagement position is compensated to ensure that the positional deviation between the compensated hydraulic cylinder engagement position and the preset target position is within a preset error range. The preset error range can be ±2 mm.

[0047] When the distance between the strip head and the shearing position is less than or equal to 10 meters, the system obtains the positional deviation between the hydraulic cylinder engagement position and the preset target position. If the positional deviation is greater than 0.7 mm, compensation is performed on the hydraulic cylinder engagement position. If the positional deviation between the hydraulic cylinder engagement position and the preset target position is greater than 0.7 mm, automatic compensation is performed, and this cycle continues until the positional deviation is less than 0.7 mm. This ensures that the positional deviation between the compensated hydraulic cylinder engagement position and the preset target position is within a preset error range.

[0048] As an optional embodiment, before obtaining the positional deviation between the hydraulic cylinder deployment position and the preset target position when the distance is within a preset distance threshold, the method may further include: adjusting the preset second deviation threshold to a preset first deviation threshold; after compensating the hydraulic cylinder deployment position when the positional deviation is greater than the preset first deviation threshold, the method may further include: if the positional deviation between the hydraulic cylinder deployment position and the preset target position is detected to be within a preset error range, then correcting the preset first deviation threshold to a preset second deviation threshold.

[0049] Specifically, when the positional deviation is greater than 0.7mm, the automatic compensation function of the hydraulic cylinder controlling the bottom rotating flap of the belt winder adjusts the positional deviation from 1.2mm to 0.7mm to compensate for the hydraulic cylinder's engagement position. If the detected positional deviation between the hydraulic cylinder's engagement position and the preset target position is within ±2mm, the positional deviation is corrected from 0.7mm to 1.2mm. For example, when the difference between the engagement position of the bottom rotating flap hydraulic cylinder and the preset target position is less than -0.2mm, the automatic compensation deviation value is corrected again from 0.7mm to the original setting of 1.2mm. This ensures that the automatic belt threading process only begins after the automatic compensation function is completed.

[0050] Therefore, in order to control problems such as the shutdown and steel stacking accidents caused by excessively low clearance between the belt winding aid tilting guide plate and the belt threading guide plate due to the slippage of the hydraulic cylinder of the belt winding aid tilting plate, the specific implementation steps of this application are as follows:

[0051] S1: When the strip is 10 meters away from the shearing (after shearing is completed, the automatic belt threading step is activated), a pulse is emitted to detect the positional deviation between the engagement position of the hydraulic cylinder of the bottom rotating flap of the belt winder and the preset target position.

[0052] S2: When the positional deviation between the bottom rotating flap hydraulic cylinder of the belt winder and the preset target position is greater than 0.7mm, the bottom rotating flap hydraulic cylinder of the belt winder will adjust the positional deviation value of the automatic compensation function from the original setting of 1.2mm to 0.7mm.

[0053] S3: If the positional deviation between the cylinder block set position and the preset target position is less than 0.7mm, the automatic compensation program will be started (because the interval between 0.7mm and 1.2mm is relatively long, the automatic compensation program can better avoid the automatic belt-threading step).

[0054] S4: When the difference between the engagement position of the bottom rotating flap hydraulic cylinder of the belt winder and the preset target position is less than -0.2mm, the automatic compensation deviation value will be corrected from 0.7mm to 1.2mm.

[0055] S5: After the automatic compensation program ends, the automatic belt-threading program begins.

[0056] In summary, the control method for a belt conveyor winding aid provided by this invention can solve problems such as the hydraulic cylinder of the belt conveyor winding aid slipping due to incomplete automatic compensation or forced stoppage of the automatic compensation program during the automatic belt threading process, leading to excessively low clearance between the belt conveyor winding aid's tilting guide plate and the threading guide plate, resulting in steel pile-up accidents. Developing reasonable institutional measures based on this method can effectively reduce the occurrence of such accidents and avoid significant economic losses.
