Description

Technical Field

[0001] The utility model relates to the technical field of steel material transportation, in particular to a system for real-time monitoring of the rotation state of a roller table. Background Art

[0002] At present, in the domestic metallurgical steel rolling industry, a cooling bed is required to effectively cool the rolled workpieces (rebar, round steel, steel pipe, etc.). The working principle of the cooling bed is to transport the rolled workpieces into the cooling bed through rollers, and then the racks gradually move the workpieces arranged on the cooling bed to the top of the cooling bed in the form of step-by-step gear shifting, so as to achieve the cooling effect of the workpieces. When the workpieces are transported to the cooling bed, due to the large number of rollers and the high temperature of the workpieces, the workpieces will be scratched if the conveying rollers do not rotate. If the maintenance personnel do not handle it in time, the workpieces will be scratched in batches, causing a lot of losses; even if it is discovered and handled in time, due to the extremely high ambient temperature at the cooling bed and the large number of rollers, it is difficult to troubleshoot and takes a long time, affecting the production rhythm.

[0003] In summary, the defects and shortcomings of the prior art are summarized as follows:

[0004] 1. Product marking requires manual spot checks, which cannot effectively detect marking problems in the first place, and easily leads to batch marking;

[0005] 2. After product marking occurs, it is impossible to determine whether it is caused by the roller table not rotating. For product quality, it is often necessary to stop the machine to investigate the cause of marking;

[0006] 3. When investigating and finding the cause of the marking, it is necessary to check the rotation of the cooling bed input roller. Due to the large number of rollers, they need to be checked manually one by one, which is time-consuming and affects the production rhythm;

[0007] 4. Under normal production conditions, maintenance personnel need to regularly inspect the rotation of the roller table, which has high safety risks and heavy workload. Utility Model Content

Therefore, it is desired that the present invention includes such modifications and variations within the scope of the appended claims and their equivalents.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0049] To solve the above problems, the present application provides a system for real-time monitoring of the rotation status of the roller table, such as Figures 1 to 6 As shown, Figure 1 A schematic diagram of the installation structure of the system for real-time monitoring of roller table rotation provided by the utility model; Figure 2 A schematic diagram of the installation structure of another embodiment of the system for real-time monitoring of roller table rotation provided by the utility model; Figure 3 for Figure 2 A top view of Figure 4 It is a schematic diagram of the installation structure of the induction sheet provided by the utility model; Figure 5 A side view of the induction sheet provided by the utility model; Figure 6 This is a schematic structural diagram of the roller table group provided by the utility model.

[0050] The above-mentioned system for real-time monitoring of the rotation state of the roller table specifically includes a sensor sheet, a rotation speed probe, a control system, an alarm and a display terminal.

[0051] Specifically, if Figure 1 and Figure 2 As shown in the figure, the induction sheet is attached to the coupling of the roller and rotates with the coupling. When the coupling rotates, the induction sheet rotates with it. The speed probe determines whether the coupling rotates by detecting the induction sheet on the coupling, and then determines whether the roller connected to the coupling rotates.

[0052] like Figure 1 and Figure 2 As shown, the speed probe is suspended at the upper end of the coupling and is at a certain distance from the coupling (the distance is the detection range of the speed probe). When the coupling rotates, the speed probe is used to detect the induction sheet attached to the coupling.

[0053] The control system is connected to the speed probe signal, and is used to receive the signal transmitted by the speed probe, and transmit the received signal to the display terminal for the operator to read.

[0054] like Figure 6 As shown, the above alarm is connected with the control system signal. When the speed probe cannot detect the sensor plate, it means that the coupling has stopped rotating. At this time, the speed probe transfers the detected signal to the alarm, and the alarm sounds, indicating that the roller table has a fault.

[0055] Furthermore, the above-mentioned display terminal is connected to the control system signal, and is used to convert the signal transmitted by the control system into a visual image for the operator to read and quickly lock the position of the roller table where the fault occurs.

[0056] Furthermore, if Figure 4 and Figure 5 As shown, in some embodiments, the induction sheet is set to be a 1 / 2 arc or 1 / 4 arc sheet structure that fits the outer wall of the coupling. Setting the shape of the induction sheet in this way can ensure that the induction sheet fits tightly with the outer wall of the coupling, and the size of the induction sheet can be set to 1 / 2 arc or 1 / 4 arc, which can be selected according to actual conditions. For example, when the diameter of the coupling is large, the induction sheet can be set to 1 / 2 arc, and when the diameter of the coupling is small, the induction sheet can be set to 1 / 4 arc. This ensures that the speed probe can better detect the induction sheet.

[0057] Furthermore, in order to ensure that the induction plate is tightly attached to the outer wall of the coupling and is not easy to fall off, the two ends of the induction plate are arranged so as not to protrude from the two end surfaces of the coupling.

[0058] Furthermore, the end of the speed probe is connected and fixed to the motor flange of the roller table through a fixing frame. Specifically, the speed measuring end of the speed probe is suspended 2mm-5mm above the induction sheet. By setting the fixing frame, the speed probe can be adjusted within the range of 2-5mm above the induction sheet.

[0059] like Figure 3 As shown, the above-mentioned fixing frame includes: a connecting end, an adjusting arm and a bearing end. The connecting end is detachably connected to the flange of the coupling. Such a setting can facilitate the removal and installation of the fixing frame from the flange of the coupling as needed, so that the fixing frame can be replaced according to actual conditions.

[0060] Specifically, if Figure 3 As shown, the above-mentioned adjustment arm is arranged between the connecting end and the bearing end, and can be used to adjust the direction and distance of the bearing end relative to the sensor sheet according to actual conditions, so that the speed probe installed thereon can better detect the existence of the sensor sheet.

[0061] Furthermore, if Figure 3 The above-mentioned bearing end is arranged at one end of the fixing frame away from the connection end, and the bearing end is used to hold the speed probe. The final position adjustment of the speed probe needs to be achieved by adjusting the length of the adjustment arm and the fixing end on the fixing frame, and adjusting the angle between the adjustment arm and the bearing end on the fixing frame.

[0062] Furthermore, if Figure 2 and Figure 3 As shown, in order to better adjust the position of the speed probe at the bearing end, the above-mentioned adjustment arm is configured to include a first arm and a second arm. The first arm is rotatably arranged on the connecting end, the second arm is rotatably arranged on the bearing end, and the first arm and the second arm are telescopically connected to adjust the length of the adjustment arm along the axis direction of the coupling.

[0063] Furthermore, the above-mentioned fixing frame also includes an auxiliary arm, the first end of the auxiliary arm is fixed to the connecting end, and the second end extends and fits onto the sensing plate to provide auxiliary fixation for the sensing plate and reduce the probability of the sensing plate falling off the coupling during rotation.

[0064] Preferably, the above-mentioned control system is a PLC control system.

[0065] Preferably, the above-mentioned display terminal can convert the signal of the control system into a WINCC screen for the operator to read.

[0066] Furthermore, if Figure 6As shown, the present application divides the roller into multiple roller resistances, and an alarm is set in each roller group, and each roller group includes 10-30 rollers. Such a setting can avoid setting an alarm next to each roller in the entire range, and a limited number of rollers are set as a roller group, and an alarm is set in a roller resistance. When a roller in the roller group does not rotate, the alarm responsible for the roller group is triggered and an alarm is issued. At this time, the operator can lock the roller group with a fault according to the position of the alarm, and check the rollers in the roller group. Such a setting not only saves the number of alarms, but also improves the efficiency of troubleshooting faulty rollers.

[0067] Preferably, the above-mentioned alarm is an audible and visual alarm.

[0068] Preferably, the thickness of the sensor sheet is in the range of 6 mm to 10 mm. The thickness of the sensor sheet is determined by the height of the speed probe suspended above it. Too high or too low will affect the accuracy of detection.

[0069] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
