[0029] Example 1

[0030] Figure 1 The first embodiment of the present invention provides a structural diagram of a trolley waist collapse detection system, as shown in FIG. Figure 1 As shown, the trolley waist collapse detection system includes: an extension rod 110, an angle detection device 120, a detection rod 130 and an early warning device 140.

[0031] Among them, the extension rod 110 is parallel to the ground, the detection rod 130 is perpendicular to the extension rod 110, the extension rod 110 and the detection rod 130 are linked, and the detection rod 130 is driven by the trolley to generate an action angle; the angle detection device 120 is connected to the extension rod 110, and the angle detection device 120 is used to collect the action angle of the detection rod 130. The early warning device 140 is connected to the angle detection device 120, and is used to receive the action angle of the detection rod 130 collected by the angle detection device 120, and determine the trolley collapse depth according to the action angle of the detection rod 130, and issue an alarm when the trolley collapse depth is greater than the depth threshold.

[0032] In this embodiment, the trolley may be a sintering trolley, which is a main operating component of a sintering machine and mainly forms a rotating chain between the head and tail wheels of the sintering machine to form a transmission cycle to achieve the purpose of sintering materials.

[0033] In this embodiment, the detection rod 130 is welded to the extension rod 110. There can be one or more detection rods, and preferably, there are three detection rods.

[0034] In this embodiment, the angle detection device may be a rotary encoder, and the warning device may be a programmable logic controller (PLC). A PLC is a digital computing and operating electronic system designed specifically for industrial environments. It features strong anti-interference capabilities, high reliability, and easy programming. It is widely used in industrial automation control (such as production line control, mechanical equipment automation, and building automation). Its core function is to process input signals through a logic control program and output control signals to achieve automated control of production processes or equipment.

[0035] In this embodiment, if Figure 2 As shown, there is a flue beneath the trolley, with a sealing plate installed on the flue wall. The extension rod is fixed to the flue wall via a bearing, that is, the extension rod is fixed to the sealing plate via a bearing. The detection rod is perpendicular to the extension rod and welded to the delay rod. As the trolley moves, it drives the detection rod. If the trolley collapses, the detection rod will move at a large angle.

[0036] In this embodiment, the depth threshold is set in relation to the length of the detection rod. The longer the detection rod is, the larger the depth threshold is set.

[0037] In this embodiment, the early warning device may determine the trolley collapse depth according to the movement angle of the detection rod by: determining the trolley collapse depth according to the movement angle of the detection rod, the length of the detection rod, a first value, and a first formula, wherein the first formula is:

[0038] +R1;

[0039] Among them, H is the depth of the trolley's waist collapse, is the action angle of the detection rod, L is the length of the detection rod, and R1 is the first value.

[0040] In this embodiment, R1 is the distance between the monitoring point of the reference trolley and the top of the detection rod. If R1 is greater than zero, that is, the monitoring point is above the top of the detection rod (no collapse or collision), then +R1; If R1 is less than zero, that is, the monitoring point is below the top of the detection rod (collision occurs even without bending), then +R1.

[0041] In a specific example, if R1=0.5, then ; If R1=-0.5, then .

[0042] It should be noted that if multiple detection rods are set up, the trolley collapse depth corresponding to each detection rod is determined based on the length of each detection rod and the movement angle of the detection rod, and the average of the trolley collapse depth corresponding to each detection rod is used as the final trolley collapse depth.

[0043] In this embodiment, if the trolley collapse depth is greater than the depth threshold, the alarm may be issued in the following manner:

[0044] If the depth of the trolley collapse is greater than the depth threshold, an opening instruction is sent to the monitoring device so that the monitoring device collects the trolley identification information;

[0045] According to the trolley identification information and the trolley collapse depth sent by the monitoring device, an alarm message is generated and an alarm is issued.

[0046] Optionally, the trolley slump detection system further includes: an angle pointer, a positioning plate, a limit plate, and a spring; the angle pointer is connected to the extension rod and is used to collect the movement angle of the detection rod; the positioning plate is perpendicular to the ground; the limit plate is connected to the positioning plate; the limit plate and the positioning plate are perpendicular; one end of the spring is connected to the positioning plate, and the other end is connected to the angle pointer. The spring and the limit plate are used to control the angle pointer to drive the extension rod to reset.

[0047] In this embodiment, the angle pointer is welded to the extension rod, and the limiting plate is welded to the positioning plate.

[0048] In this embodiment, the positioning plate can also serve as an angle display plate for displaying the movement angle of the detection rod.

[0049] In this embodiment, after the angle pointer detects the movement angle of the detection rod, it can display the movement angle of the detection rod in real time. The movement angle of the detection rod detected by the angle pointer can also be used to correct the movement angle of the detection rod detected by the angle detection device, thereby improving the accuracy of the movement angle of the detection rod detected by the angle detection device.

[0050] In this embodiment, the spring cooperates with the limiting plate so that the angle pointer drives the extension rod to reset.

[0051] Optionally, the trolley slump detection system further includes: an angle detection device fixing plate, wherein the angle detection device fixing plate is used to fix the angle detection device to the ground or to a positioning plate.

[0052] In this embodiment, the angle detection device is fixed to the ground or to the positioning plate by using the angle detection device fixing plate, which can improve the detection accuracy of the angle detection device.

[0053] Optionally, the trolley sagging detection system further includes: a monitoring device; the monitoring device is used to collect trolley identification information and send the trolley identification information to the early warning device.

[0054] In this embodiment, the monitoring device may be a camera, which collects the trolley image through the camera, identifies the trolley image, and obtains the trolley identification information.

[0055] In this embodiment, the trolley identification information may be a trolley number.

[0056] Optionally, the length of the detection rod is equal to the difference between the distance between the monitoring point of the reference trolley and the extension rod and the first value.

[0057] In this embodiment, the monitoring point of the reference trolley is the bottom position of the reference trolley. The reference trolley is a normally operating trolley (that is, a trolley without a sagging waist problem). The monitoring point of the reference trolley can be a position at which the bottom of the trolley is likely to deform if the trolley has a sagging waist problem. The selection of the monitoring point is related to the setting position of the detection rod. The monitoring point is the position at which the detection rod will generate an action angle if the trolley has a sagging waist problem.

[0058] In this embodiment, the first value may be a positive number or a negative number. For example, the first value may be +0.5 or -0.5.

[0059] It should be noted that when the first value is a positive number, the depth threshold set is smaller than the depth threshold set when the first value is a negative number.

[0060] Optionally, the trolley collapse detection system further includes: a bearing, which is mounted on the flue wall and is used to support an extension rod to ensure linkage between the extension rod and the detection rod.

[0061] In a specific example, Figure 3a and Figure 3b As shown, the bearing is installed on the flue wall, and the bearing is used to support the extension rod, which is parallel to the ground. The detection rod L1, detection rod L2, detection rod L3 and angle pointer are welded on the extension rod. The detection rod L1, detection rod L2, detection rod L3 and angle pointer are all perpendicular to the extension rod. The limit plate, positioning plate and rotary encoder are all set outside the trolley driving area. The rotary encoder is connected to the extension rod, the positioning plate is perpendicular to the ground, the limit plate is welded on the positioning plate, the limit plate and the positioning plate are perpendicular, one end of the spring is connected to the positioning plate, and the other end is connected to the angle pointer. The spring is parallel to the limit plate, and the spring and the limit plate are parallel to the ground. When the trolley collapses, the trolley drives the detection rod to generate an action angle. After the bottom surface of the trolley is no longer in contact with the detection rod, the spring drives the angle pointer to reset. Since the angle pointer, detection rod and extension rod are linked, the detection rod and extension rod are also driven by the spring, thereby achieving reset to perform collapse detection on the next trolley. Since the rotary encoder is connected to the extension rod, and the extension rod is linked to the detection rod, the change in the angle of the extension rod may affect the measurement accuracy of the rotary encoder. In this embodiment, the rotary encoder is fixed to the ground by a fixing plate of the angle detection device to improve the measurement accuracy of the rotary encoder. After detecting that the depth of the trolley collapse is greater than the depth threshold, an open command is sent to the monitor, the monitor collects the trolley identification information, and the monitor sends the trolley identification information to the early warning device, so that the early warning device generates an alarm message based on the trolley identification information sent by the monitor and the trolley collapse depth, and issues an alarm.

[0062] Example 2

[0063] Figure 4 This is a flow chart of a method for detecting a trolley sagging provided by an embodiment of the present invention. This embodiment is applicable to the case of detecting a trolley sagging. The method can be executed by the early warning device in the above embodiment, which can be implemented in software and / or hardware. Figure 4 As shown, the method specifically includes the following steps:

[0064] S410: Receive the movement angle of the detection rod collected by the angle detection device.

[0065] In this embodiment, the early warning device may be a programmable logic controller (PLC).

[0066] In this embodiment, the action angle may be a rotation angle.

[0067] In this embodiment, the detection rod is driven by the trolley to generate an action angle. It should be noted that if the length of the detection rod is set to the difference between the distance between the monitoring point of the reference trolley and the extension rod and the first value, and the first value is a positive number, then as long as the trolley is in contact with the detection rod, it will drive the detection rod to cause the detection rod to generate an action angle. If the length of the detection rod is set to the difference between the distance between the monitoring point of the reference trolley and the extension rod and the first value, and the first value is a negative number, then only when the probability of the trolley collapsing is high, the trolley will contact the detection rod and drive the detection rod to cause the detection rod to generate an action angle.

[0068] In this embodiment, the method of receiving the movement angle of the detection rod collected by the angle detection device can be: the angle detection device collects the movement angle of the detection rod in real time, the angle detection device sends the collected movement angle of the detection rod to the early warning device, and the early warning device receives the movement angle of the detection rod collected by the angle detection device.

[0069] S420, determining the collapse depth of the trolley according to the movement angle of the detection rod.

[0070] In this embodiment, the method of determining the trolley collapse depth based on the movement angle of the detection rod can be: taking the maximum value of the received movement angles of the detection rod as the target movement angle, and determining the trolley collapse depth based on the target movement angle.

[0071] In this embodiment, the method of determining the trolley collapse depth according to the target action angle can be: determining the trolley collapse depth according to the cosine value of the target action angle of the detection rod and the length of the detection rod.

[0072] For example, the product of the difference between 1 and the cosine value of the target operating angle of the detection rod and the length of the detection rod may be used as the trolley collapse depth.

[0073] Optionally, the trolley collapse depth is determined based on the movement angle of the detection rod, including:

[0074] The trolley collapse depth is determined according to the movement angle of the detection rod, the length of the detection rod, the first value and the first formula, wherein the first formula is:

[0075] +R1;

[0076] Among them, H is the depth of the trolley's waist collapse, is the action angle of the detection rod, L is the length of the detection rod, and R1 is the first value.

[0077] In this embodiment, the movement angle of the detection rod may be the maximum value of the movement angle of the detection rod collected by the angle detection device, or may be a peak value.

[0078] S430: If the depth of the trolley collapse is greater than the depth threshold, an alarm is issued.

[0079] In this embodiment, the depth threshold is determined according to the length of the detection rod.

[0080] In this embodiment, if the trolley collapse depth is greater than the depth threshold, an alarm signal is output to the pyrotechnician collapse alarm device, and alarm data is displayed at the same time. The alarm data includes: the trolley collapse depth, or the trolley collapse depth and trolley identification information.

[0081] Optionally, if the trolley collapse depth is greater than a depth threshold, an alarm is issued, including:

[0082] If the trolley's waist collapse depth is greater than the depth threshold, an opening instruction is sent to the monitoring device to enable the monitoring device to collect the trolley identification information.

[0083] In this embodiment, the monitoring device may be a camera, or other devices for collecting images, which is not limited in this embodiment of the present invention.

[0084] In this embodiment, the trolley identification information may be a trolley number.

[0085] According to the trolley identification information and the trolley collapse depth sent by the monitoring device, an alarm message is generated and an alarm is issued.

[0086] In this embodiment, the monitoring device is arranged at a preset distance in front of the positioning plate, and the front of the positioning plate is the traveling direction of the trolley.

[0087] In this embodiment, the monitoring device is arranged outside the trolley driving area and is capable of photographing the location area of ​​the trolley identification information.

[0088] In this embodiment, the rotary encoder detects the movement angle of the detection rod and transmits the movement angle to the PLC. When the movement angle is greater than 0°, the program starts to start, records the maximum movement angle, and when the movement angle is maximum, controls the monitoring device to take a photo, and uses Python to read the numbers in the photo (OCR text recognition) and record the trolley number.

[0089] It should be noted that the trolley numbers and trolley collapse depths recorded over a long period of time can also be used to analyze the degradation trend of each trolley within the target time period, and the timing of the trolley maintenance can be noted in the table.

[0090] In this embodiment, the maintenance time can be determined based on the difference between the collapse depth and the threshold, as well as the current time.

[0091] In this embodiment of the present invention, an extension rod is used to transfer internal detection to the outside. The angle of the detection rod is used to calculate the depth of the collapsed trolley. Network communication technology is then used to upload the collapsed trolley data to the terminal of the pyrotechnician, who can then determine whether to replace the trolley or implement a scheduled maintenance plan. The system also records and analyzes trolley degradation trends.

[0092] The technical solution of this embodiment is to determine the trolley waist collapse depth according to the movement angle of the detection rod collected by the receiving angle detection device; if the trolley waist collapse depth is greater than the depth threshold, it means that the trolley has a waist collapse problem and an alarm is issued.
