[0026] Example

[0027] Reference Figure 1 A consumable wear detection and early warning device comprises: a bracket 1, a support platform 2, a detection mechanism and an early warning mechanism, the bracket 1 is fixedly arranged on the rail web, at least one support platform 2 is arranged, and the support platform 2 is connected to the bracket 1; the support platform 2 is provided with an early warning mechanism and a detection mechanism, and the detection mechanism is used to detect the wear degree of the brush.

[0028] Specifically, the bracket 1 is arranged in an L shape, and the short side of the L-shaped bracket is arranged at the rail web A and is connected and fixed to the rail web A, and the long side of the bracket 1 is in a vertical state with the rail web A; a plurality of support platforms 2 are arranged on the long side of the bracket 1, and the support platforms 2 are arranged in three in this embodiment, all of which are arranged on the same side of the bracket 1, and each support platform 2 is on the same horizontal line, and the support platform 2 and the rail web A are arranged in parallel.

[0029] Specifically, the distance sensor 3 is arranged on one side of the bracket 1. Since the brush B moves through the line, in this embodiment, the distance sensor 3 is arranged on the side of the bracket 1 closest to the brush B, which can detect the position of the brush B most quickly and accurately; a number of displacement sensors 4 are arranged on the supporting platform 2. In this embodiment, two displacement sensors 4 are arranged on each layer of the supporting platform 2, and a connecting hole is arranged at the bottom of the displacement sensor 4. The connecting hole of the displacement sensor 4 and the threaded hole arranged on the supporting platform 2 are fixed by bolts to complete the setting of the displacement sensor 4.

[0030] Specifically, the early warning mechanism is provided with a warning light 5, which is arranged on the top of the bracket 1, and the light color of the warning light 5 is set to blue-purple, so as to conveniently remind the staff.

[0031] The power supply of the device in this embodiment comes from the electric control power supply system, which is connected to the control box through a signal line. The control box has a built-in control module of the early warning mechanism. The wear amount is judged and predicted through the internal transformation of the PLC system, and the on-site alarm prompt is realized through the warning light 5. At the same time, the alarm signal and measurement data are uploaded to the upper system, and the upper system can also realize the alarm display function at the same time.

[0032] The working principle of this embodiment:

[0033] When the conveyor belt brush B reaches the wear detection position, brush B just enters the measuring position of the distance sensor 3, and brush B blocks the displacement sensor 4, thereby triggering the displacement sensor to measure the distance; the distance measurement data of the displacement sensor 4 and the new brush are set as standard data, and the distance measurement data of the displacement sensor 4 and the brush B driven by the conveyor are set as real-time data. By comparing the real-time data and the standard data, the wear data of the brush B is obtained. When the wear degree exceeds the range of the standard data, the PLC system program will generate an alarm message to remind the staff that this conveyor is no longer receiving vehicles for electrophoresis, so as to avoid quality defects of the vehicle body electrophoresis.

[0034] Furthermore, the configuration software CIM of the upper system periodically collects and analyzes the brush wear data from the PLC side through the Ethernet protocol, and calls the predictive maintenance module in the configuration software to predict the time when brush B will wear out. Engineers can remotely access relevant web pages, receive remote information push, implement remote monitoring, and promptly remind staff to check and replace, thereby playing a role in preventive maintenance.

[0035] Furthermore, the device of this embodiment receives the distance signal of the distance measuring sensor 3, and the signal line is connected to the Siemens IO module. After the information is fed back to the module, the module is configured in the Siemens PLC system. The PLC receives the actual position of the wear device to the brush B through the configuration at this time, and sets the minimum test straight-line distance from the displacement sensor 4 to the brush B to 68 mm.

[0036] The PLC compares the position sizes. If it is greater than 67mm and less than 69mm, it is in the normal range of brush B and no processing is required. If it is greater than 69mm and less than 70mm, a warning is issued to indicate that brush B is worn. If it is greater than 70mm, an alarm is issued to indicate that brush B is damaged and requires personnel treatment, and production must be stopped. If it is less than 67mm, the program will mark a reminder and the device in this embodiment needs self-inspection.

[0037] Furthermore, the upper system CIM calls the predictive maintenance module to make a time judgment; the initial distance is 68mm, and after 1 month, it becomes 68.1mm; after 3 months, it becomes 68.3mm; after 6 months, it becomes 68.6mm, which is basically a linear loss. From then on, it becomes 70mm, which is expected to take 20 months. In this way, by the 20th month, the brush does not alarm, and the upper system prompts the engineer to check the brush condition and replace it if necessary.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
