Description

Technical Field

[0001] This utility model belongs to the field of mining machinery technology, and in particular relates to an intelligent monitoring device for mining spiral idlers. Background Technology

[0002] Mining spiral idlers are a special type of idler specifically designed for mining conveying systems. Their most distinctive feature is the continuous spiral ridges or grooves machined on the outer surface of the roller. Because they are specifically designed for mining, they possess some unique characteristics compared to other idler sets, such as self-cleaning, anti-adhesion, and self-correction.

[0003] However, mining spiral idlers require longer operating times compared to other idlers, making them more susceptible to wear or other abnormalities. These inspections mostly rely on manual patrols, requiring periodic shutdowns to check for issues such as idler wear and abnormal temperatures. This is inefficient, poses safety hazards, and lacks data support, making it impossible to obtain key parameters such as idler vibration and temperature in real time, thus making it difficult to provide early warnings of malfunctions.

[0004] To address these issues, we propose an intelligent monitoring device for mining spiral idlers. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing an intelligent monitoring device for mining spiral idlers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart monitoring device for mining spiral idlers includes an idler body and a bushing. The idler body is rotatably connected to the side wall of the bushing. A casing is fastened to the side wall of the bushing. A vibration sensor and a temperature sensor are installed in the casing. A communication chip is also installed in the casing. The temperature sensor passes through the side wall of the idler body. The vibration sensor abuts against the side wall of the idler body. A working cavity is formed in the side wall of the bushing. An observation window is formed in the side wall of the working cavity. A counting mechanism is installed inside the working cavity. The side wall of the counting mechanism abuts against the casing.

[0008] Preferably, the communication chip is a LoRa chip, and a photovoltaic panel is disposed outside the package, the photovoltaic panel providing power to the communication chip.

[0009] Preferably, the counting mechanism includes a turntable, a locking block, a moving plate, and a protrusion. The turntable is rotatably connected to the side wall of the working cavity. The turntable is provided with several partitions, each of which is marked. The observation window faces one of the marks. The side wall of the partition is provided with a slot. The locking block and the moving plate are slidably connected to the side wall of the working cavity. The locking block is engaged in the slot. The moving plate is fixedly disposed on the side wall of the locking block. The protrusion is fixedly disposed on the side wall of the moving plate. The protrusion abuts against the side wall of the encapsulation shell.

[0010] Preferably, a telescopic spring is installed on the side wall of the motion plate, and the other end of the telescopic spring is fixedly connected to the side wall of the working cavity.

[0011] Preferably, the end of the bump facing the packaging shell has an arc-shaped design, and the bump is located inside the working cavity.

[0012] Preferably, the turntable is close to the top of the working chamber, and the observation window is hollow.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. This application uses temperature and vibration sensors for real-time monitoring, dynamically collecting data on roller vibration and temperature, and promptly detecting anomalies. The communication chip enables remote early warning, uploading data to the monitoring center via a wireless network, and supports remote fault diagnosis. Furthermore, analysis of the data transmitted from the communication chip can extend equipment lifespan. Optimizing maintenance cycles based on data analysis can reduce unnecessary losses. Through multi-parameter fusion analysis, the fault identification accuracy can be improved to over 95%, thereby reducing operating costs and preventing conveyor belt tearing or downtime accidents caused by roller failures, thus ensuring production safety.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-4 As shown, a smart monitoring device for a mining spiral idler roller includes an idler roller body 1 and a bushing 2. The idler roller body 1 is rotatably connected to the side wall of the bushing 2. A casing 3 is fastened to the side wall of the bushing 2. The casing 3 can be fixed to the side wall of the bushing 2 by means of snap-fit, etc., for easy disassembly. A vibration sensor 4 and a temperature sensor 5 are installed in the casing 3. The vibration sensor 4 is piezoelectric, and the temperature sensor 5 is a thermocouple sensor. A communication chip 6, which is a LoRa chip, is also installed in the casing 3. A photovoltaic panel 8 is installed outside the casing 3, and the photovoltaic panel 8 supplies power to the communication chip 6. LoRa is a linear frequency modulation spread spectrum IoT modulation technology, also known as wideband chirp modulation technology. Compared with the traditional FSK technology, LoRa has a longer transmission distance at the same power consumption and strong anti-interference ability, making it particularly suitable for mining applications. It can encrypt the data from the temperature sensor 5 and the vibration sensor 4 before transmitting it to the ground monitoring terminal.

[0023] Temperature sensor 5 passes through the side wall of roller body 1, vibration sensor 4 abuts against the side wall of roller body 1, working cavity is opened in the side wall of bushing 2, observation window 7 is opened in the side wall of working cavity, counting mechanism is installed inside working cavity, the side wall of the counting mechanism abuts against the encapsulation shell 3, counting mechanism includes turntable 9, card block 10, moving plate 11 and protrusion 12, turntable 9 is rotatably connected to the side wall of working cavity, turntable 9 is provided with several partitions 13, each partition 13 is provided with a mark, observation window 7 is directly opposite one of the marks, the marking method includes but is not limited to numbers, letters or colors, as long as each mark is different and easy for the staff to identify, turntable 9 is close to the top of working cavity, observation window 7 is hollow design, with the encapsulation shell 3 removed, the staff can turn turntable 9 through observation window 7, the marks on turntable 9 can help count, thereby helping the staff to quickly understand the wear of roller body 1.

[0024] The partition 13 has a slot 14 on its side wall. The locking block 10 and the moving plate 11 are slidably connected to the side wall of the working cavity. The locking block 10 is engaged in the slot 14. The moving plate 11 is fixedly installed on the side wall of the locking block 10. The protrusion 12 is fixedly installed on the side wall of the moving plate 11. The protrusion 12 abuts against the side wall of the encapsulation shell 3. The end of the protrusion 12 facing the encapsulation shell 3 has an arc design. The protrusion 12 is located inside the working cavity. After the encapsulation shell 3 is installed, the encapsulation shell 3 will push the protrusion 12 toward the turntable 9, thereby causing the moving plate 11 to drive the locking block 10 into the slot 14, thereby fixing the position of the turntable 9 and fixing the mark on the turntable 9.

[0025] A telescopic spring 15 is installed on the side wall of the moving plate 11. The other end of the telescopic spring 15 is fixedly connected to the side wall of the working cavity. The setting of the telescopic spring 15 makes the moving plate 11 and the locking block 10 have a tendency to move towards the encapsulation shell 3. Therefore, without the restriction of the encapsulation shell 3, the locking block 10 will leave the turntable 9, and the turntable 9 will be in a rotatable state, which makes it convenient for the staff to adjust the position of the turntable 9 and the mark.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
