Description

Technical Field

[0001] The present invention relates to the field of metallurgical technology, and in particular to a method and device for detecting wheel fall of a ring cooler trolley and a ring cooler. Background Art

[0002] In the sintering ring cooling system of modern metallurgical enterprises, the ring cooling trolley plays an important role in transporting the sintered ore from the sintering machine to the cooling process. Since the trolley's travel path is circular rather than linear, and the contact surface between the wheel and the track is subject to complex force distribution, there is a possibility that the trolley wheels move relative to each other along the inner and outer rings.

[0003] However, when this displacement reaches a certain threshold, it may cause the wheel to separate from the track, which is called "wheel drop". In large-scale annular coolers, the "wheel drop" phenomenon is often not discovered in time, resulting in major accidents such as deformation, derailment, and jamming of the trolley, causing economic losses.

[0040] In the related art, the annular cooler 10 is often not found in time due to the "wheel drop" phenomenon, which leads to major accidents such as deformation, derailment, and jamming of the trolley 105, resulting in economic losses.

[0041] In view of the above problems, the present invention provides a method and device for detecting wheel fall of a ring cooler trolley and a ring cooler 10, which can detect wheel fall of the trolley 105 in time, give a warning, and avoid further expansion of the accident.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0047] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0048] See also Figure 1 and Figure 2 The embodiment of the present invention provides a ring cooler trolley wheel drop detection method and a ring cooler trolley wheel drop detection device 20, which are applied to a ring cooler 10. The ring cooler 10 may include a memory 110 and one or more processors 120.

[0049] The memory 110 and the processor 120 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these elements can be electrically connected to each other through one or more communication buses or signal lines. The ring cooler trolley wheel drop detection device 20 includes at least one software function module that can be stored in the memory 110 in the form of software or firmware or solidified in the operating system (OS) of the server. The processor 120 is used to execute executable modules stored in the memory 110, such as software function modules and computer programs included in the ring cooler trolley wheel drop detection device 20.

[0050] The memory 110 may be, but is not limited to, a random access memory 110 (RAM), a read only memory 110 (ROM), a programmable read-only memory 110 (PROM), an erasable programmable read-only memory 110 (EPROM), an electrically erasable read-only memory 110 (EEPROM), etc. The memory 110 is used to store computer program codes, and the computer program codes include computer instructions. When one or more processors 120 execute the computer instructions, the processors 120 execute the ring cooler trolley wheel drop detection method.

[0051] See also Figure 3 The method for detecting wheel fall of the cooling machine trolley provided in this embodiment may include the following steps:

[0052] Step S100 , obtaining the motion information corresponding to each trolley 105 in the detection section entering the ring cooler 10 ; wherein the detection section is determined by at least two groups of detection components 107 .

[0053] Before step S100, at least two groups of detection components 107 can be sequentially arranged in the section close to the material discharge entrance in the trolley travel track 103 according to the shape of the trolley 105 of the sintering ring cooler 10 and the situation of the trolley travel on the track 103. It is easy to understand that the distance between the detection component 107 at the head end and the detection component 107 at the head end is the detection section. Accordingly, the motion information is also the information obtained by the detection component 107.

[0054] Step S200: If the motion information meets the preset fault condition, an alarm signal is issued.

[0055] In step S200, when the motion information detected by the detection component 107 meets the corresponding preset fault condition, an alarm signal is issued.

[0056] Step S300, obtaining the number of times the alarm is issued.

[0057] In step S200, since each detection component 107 can send out an alarm signal, theoretically the maximum number of times an alarm signal is sent out is the number of groups of detection components 107. Based on this, the number of groups of detection components 107 can be limited according to actual needs, ensuring that there are two groups with a gap between them, and at least two alarm signals can be sent out.

[0058] Step S400: If the number of alarms issued meets the preset number, a fault handling instruction is output.

[0059] In step S400, it is easy to understand that when the number of alarms does not meet the preset number, the annular cooler 10 operates normally. When the number of alarms meets the preset number, the corresponding fault handling instructions instruct the staff to respond to the abnormal situation in time to avoid further expansion of the accident.

[0060] Further, one of the detection components 107 is defined as a first detection component, and the first detection component includes two first detectors located on both sides of the trolley travel track 103. Based on this, the corresponding motion information is the detection time interval of the coaxial wheels (coaxial front wheels or coaxial rear wheels) detected by the two first detectors respectively, and if the detection time interval is greater than the preset time interval, the preset fault condition is met.

[0061] Taking into account that the outer circumference of the trolley travel track 103 is larger and travels a longer path, in order to ensure that the two first detectors should detect the position information of the coaxial wheels synchronously or tend to be synchronous, since the outer circumference is larger and the corresponding wheels travel a longer path, the installation position of the outer first detector is closer to the feed port 101 than the installation position of the inner first detector.

[0062] It is easy to understand that the inner first detector is used to detect the passing signal of the inner wheel, and the outer first detector is used to detect the passing signal of the outer wheel. Therefore, within the preset time interval, if the first detector at one location detects a signal and the first detector at the other location does not detect a signal, the fault condition is met and an alarm signal is issued.

[0063] Taking the preset time interval of 15s as an example, when the first detector on the inner side detects the passing signal of the corresponding wheel, and the first detector on the outer side does not detect the passing signal of the corresponding wheel within 15s, an alarm signal is issued. Conversely, when the first detector on the outer side detects the passing signal of the corresponding wheel, and the first detector on the inner side does not detect the passing signal of the corresponding wheel within 15s, an alarm signal is also issued.

[0064] In the present application, the first detector is specifically a grounding switch, powered by a 220V power supply. When the wheels of the trolley 105 pass through the detection range of the proximity switch, the proximity switch is triggered to turn on, and the voltage signal is transmitted remotely to the PLC control system. When the wheels of the trolley 105 leave the detection range of the proximity switch, the proximity switch is disconnected and no longer sends a signal to the PLC control system.

[0065] In some embodiments, there are two sets of first detection components, and the distance between the two first detection components is greater than the total length of the vehicle 105, so as to ensure that the two sets of first detection components located at different positions can detect the passing signal of the same coaxial wheel. In other words, the same coaxial wheel of the same vehicle 105 is detected twice and can generate two alarm signals.

[0066] In other embodiments, one of the detection components 107 may be defined as the second detection component, and the first detection component and the second detection component are arranged at intervals along the travel direction of the trolley 105. In other words, the first detection component is arranged close to the feed port 101, and the second detection component is arranged away from the feed port 101. In addition, the spacing between the first detection component and the second detection component is smaller than the total length of the trolley 105, so as to ensure that the first detection component and the second detection component obtain the motion information of the same trolley 105.

[0067] On the basis of the above, the second detection component includes a second detector located on one side of the trolley travel track 103. Based on this, the corresponding motion information is the inclination angle of the vehicle body detected by the second detector. If the inclination angle is greater than the preset angle, the preset fault condition is met and an alarm signal is issued. It is easy to understand that the second detection component can be set on the inside or outside of the trolley travel track 103, which is not limited in this application. In this combined design, the coaxial wheels and body of the same trolley 105 are detected, and in a shorter detection section, two signals can be issued.

[0068] In other embodiments, one of the detection components 107 may be defined as the third detection component, and the first detection component and the third detection component are arranged at intervals along the travel direction of the trolley 105. Similar to the above, the first detection component is arranged close to the feed port 101, and the third detection component is arranged away from the feed port 101. In addition, the spacing between the first detection component and the third detection component is less than the total length of the trolley 105, so as to ensure that the first detection component and the third detection component obtain the motion information of the same trolley 105.

[0069] On the basis of the above, the third detection component includes a third detector located on both sides of the trolley travel track 103. Based on this, the corresponding motion information is that the two third detectors respectively detect the inclination deviation value of the vehicle body; if the inclination deviation value is greater than the preset deviation value, the preset fault condition is met and an alarm signal is issued. Similar to the above, in this combined design, the coaxial wheels and the vehicle body of the same trolley 105 are both detected, and two signals can be issued in a shorter detection section.

[0070] It is easy to understand that the second detection component and the third detection component can also be used in combination with the two first detection components, that is, they are located between the two first detection components to improve the accuracy of wheel fall detection and avoid the expansion of accidents. In addition, similar to the above-mentioned second detection component and the third detection component, an inclinometer can also be installed on the inner and outer bodies of each trolley 105. The inclinometer can measure the inclination angle of the trolley 105 with the horizontal plane during driving when the trolley 105 travels to the detection section, and monitor the driving status of the trolley 105.

[0071] Accordingly, similar to the second detection component, when the inner inclinometer detects that the inward tilt value is greater than the preset range, it is determined that the preset fault condition is met and an alarm is issued; when the outer inclinometer detects that the outward tilt value is greater than the preset range, it is determined that the preset fault condition is met and an alarm is issued. Alternatively, similar to the third detection component, when the deviation between the inward tilt value and the outward tilt value is greater than the preset range, it is determined that the preset fault condition is met and an alarm is issued.

[0072] Considering that the travel speed of the trolley 105 is constant and the spacing between the detection sections is constant, in some embodiments, the movement information is the travel time through the detection section; if the travel time is greater than the preset time, it means that the travel is abnormal, the preset fault condition is met, and an alarm is issued. In addition, it is also possible to judge whether the detection component 107 is faulty according to the travel time. If the detection component 107 is not triggered during the travel time, the PLC transmits a maintenance instruction to remind the operator to repair it in time.

[0073] See also Figure 4If the number of alarms meets the preset number, the steps of outputting the fault handling instruction include:

[0074] Step S410: if the number of alarms is equal to the first preset number, a check instruction is output.

[0075] In step S410, the first preset number of times refers to 1. Therefore, when the trolley 105 passes through the detection section and only receives one alarm, it means that the trolley 105 has a tendency to lose wheels, and the PLC will output an inspection instruction to the monitoring computer screen, display the fault information corresponding to the alarm, and remind the operator to go to the sintering ring cooler 10 for on-site inspection and timely processing to reduce losses.

[0076] Step S430: If the number of alarms is greater than or equal to a second preset number, a shutdown command is output.

[0077] In step S430, the second preset number of times refers to 2 times. Therefore, when the trolley 105 passes through the detection section and receives two or more alarms, it means that the trolley 105 has lost wheels. The PLC will output a shutdown command to the monitoring computer screen to remind the operator to stop the machine in time to avoid continuous wheel loss of the trolley 105 and expand the impact of the accident.

[0078] As an optional embodiment, after the step of outputting a shutdown instruction if the number of alarms is greater than or equal to the second preset number, the method further includes:

[0079] Step S431, generating a shutdown interface according to the shutdown instruction; wherein the shutdown interface includes a shutdown indication key of the ring cooler 10.

[0080] In step S431, it should be noted that the PLC will generate a shutdown interface on the monitoring computer screen according to the shutdown instruction, reminding the staff to click the shutdown instruction key to execute the shutdown instruction. Optionally, if the shutdown instruction key is not manually triggered within 5 seconds, the shutdown instruction key is automatically triggered.

[0081] Step S433, in response to the user's operation of the stop indication key, the ring cooler 10 is controlled to shut down.

[0082] In step S433, it should be noted that the stop indicator key interlocks the unlocking switch button in the annular cooler 10. When the stop indicator key is triggered, the interlocking protection function of the annular cooler 10 responds and automatically performs the corresponding protection action, that is, stops the equipment from running to prevent accidents.

[0083] In summary, the ring cooler trolley wheel drop detection method provided in the embodiment of the present invention can obtain the motion information corresponding to each trolley 105 in the detection section of the ring cooler 10, so as to issue an alarm signal when the motion information meets the preset fault condition. Correspondingly, the number of times the alarm is issued can also be obtained, so as to output a fault handling instruction when the number of times the alarm is issued meets the preset number. Based on this, it is convenient to detect and feedback the operating status of the trolley 105 in a timely manner, solve the problem that the wheel drop of the trolley 105 cannot be discovered in time, avoid further expansion of the accident, and save production costs.

[0084] See also Figure 5 The ring cooler trolley wheel drop detection device 20 provided in this embodiment includes an acquisition module 210 and a control module 230. The acquisition module 210 is used to obtain the motion information corresponding to each trolley 105 and the number of alarms issued in the detection section of the ring cooler 10. The control module 230 is used to issue an alarm signal if the motion information meets the preset fault condition; if the number of alarms meets the preset number, output a fault handling instruction.

[0085] Optionally, the acquisition module 210 can be specifically used to execute step S100 and step S300 in the above detection method to achieve corresponding technical effects. The control module 230 can be specifically used to execute step S200 and step S400 in the above detection method to achieve corresponding technical effects. Optionally, the control module 230 can execute step S410, step S410 and step S433, and the acquisition module can also execute step S431.
