[0026] like Figures 1 to 3As shown, in this embodiment, the vibration monitoring device is used to monitor the vibration of the coal mine electromechanical equipment 100. The vibration monitoring device includes: a support 10, a winding structure 20, a transmission structure 30, a clamping structure 40, and a dustproof structure 50. The support 10 is located on the outside of the coal mine electromechanical equipment 100. The winding structure 20 is disposed on the support 10, and a recording paper 21 is disposed on the winding structure 20. The transmission structure 30 is spaced apart from the support 10 and abuts against the coal mine electromechanical equipment 100. The clamping structure 40 is disposed on the transmission structure 30 and corresponds to the recording paper 21. The clamping structure 40 is used to clamp the recording pen. The dustproof structure 50 covers the winding structure 20, the transmission structure 30, and the clamping structure 40.

[0027] Applying the technical solution of this embodiment, the vibration monitoring device can monitor the vibration of coal mine electromechanical equipment 100. The vibration monitoring device includes a support 10, a winding structure 20, a transmission structure 30, a clamping structure 40, and a dustproof structure 50. The support 10 is located on the outside of the coal mine electromechanical equipment 100. The winding structure 20 is mounted on the support 10 and has recording paper 21 mounted on it. The transmission structure 30 is spaced apart from the support 10 and abuts against the coal mine electromechanical equipment 100. The clamping structure 40 is mounted on the transmission structure 30 and corresponds to the recording paper 21, and can clamp a recording pen. The dustproof structure 50 covers the winding structure 20, the transmission structure 30, and the clamping structure 40. Through the above configuration, the vibration monitoring device can record the vibration of the coal mine electromechanical equipment 100 in real time, providing important data for equipment maintenance and fault prediction. It is suitable for vibration monitoring of various electromechanical equipment in underground coal mines, thereby helping to improve the stability and safety of equipment operation. Specifically, by setting a support 10 on the outside of the coal mine electromechanical equipment 100, and cooperating with a winding structure 20, a transmission structure 30, a clamping structure 40, and a dustproof structure 50, real-time recording and monitoring of equipment vibration is achieved. Simultaneously, the dustproof structure 50 effectively prevents dust in the coal mine environment from affecting the monitoring device, ensuring the cleanliness of the recording paper 21 and the normal operation of the recording pen, thus improving the accuracy and reliability of the monitoring data. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where vibration detection equipment is easily affected by dust, thereby affecting the monitoring effect.

[0028] like Figures 1 to 3As shown in this embodiment, the vibration monitoring device is specially designed with a dustproof structure 50, which can effectively isolate the high-dust environment underground in coal mines, ensuring the cleanliness of the recording paper 21 and the recording pen, thereby improving the accuracy of the monitoring data. In underground coal mines, equipment such as coal mining machines, conveyors, and hoists operate in high-dust environments for extended periods. Vibration monitoring data from these machines is crucial for predicting equipment failures and improving operational efficiency. The application of this device not only helps coal mining companies monitor equipment status in real time but also provides early warnings of potential equipment problems through data analysis, reducing unplanned downtime, lowering maintenance costs, and significantly improving the safety and economic benefits of coal mine production.

[0029] like Figures 1 to 3 As shown, in this embodiment, the dustproof structure 50 includes a top plate 51, a connecting rod 52, and a dustproof curtain 53. The connecting rod 52 is disposed between the winding structure 20 and the top plate 51, and the dustproof curtain 53 surrounds the outer periphery of the top plate 51. This dustproof structure 50 can effectively isolate dust and impurities in the coal mine environment, protect the internal winding structure 20, transmission structure 30, and clamping structure 40, ensure the cleanliness of the recording paper 21 and recording pen, and improve the accuracy of monitoring data. It is suitable for high-dust environments in underground coal mines, ensuring the normal operation of the monitoring device under harsh conditions.

[0030] like Figures 1 to 3 As shown, in this embodiment, the dustproof structure 50 is designed with the special working environment of underground coal mines in mind. The combination of the connecting rod 52 and the dustproof curtain 53 not only effectively blocks the intrusion of external dust and impurities, but also reduces the dust generated by internal components due to vibration, keeping the internal environment of the device clean. This is crucial for monitoring devices that operate underground in coal mines for extended periods, as the accumulation of dust and impurities can affect the precise movement of the transmission structure 30 and the clamping structure 40, thereby affecting the accuracy of the recording. With this dustproof structure 50, even in extremely harsh environments, the vibration monitoring device can maintain high-precision vibration records, providing reliable data support for the health status of the equipment. It is particularly suitable for coal mine equipment that requires frequent vibration monitoring, such as crushers and ventilators, helping coal mining enterprises achieve refined management and preventative maintenance.

[0031] like Figures 1 to 3As shown, in this embodiment, the dustproof structure 50 further includes a first clamping plate 54, a second clamping plate 55, and a first driving member 56. The first clamping plate 54 and the second clamping plate 55 are spaced apart on both sides of the top plate 51. The first driving member 56 can drive the first clamping plate 54 and the second clamping plate 55 to move. The first clamping plate 54 and the second clamping plate 55 have a clamping state where they are close to each other and a loosening state where they are far apart from each other. When the first clamping plate 54 and the second clamping plate 55 switch from the loosening state to the clamping state, the dustproof curtain 53 is clamped between the first clamping plate 54 and the top plate 51, and between the second clamping plate 55 and the top plate 51. This design makes the dustproof curtain 53 more firmly fixed, preventing the dustproof curtain 53 from shifting when the equipment vibrates, further improving the dustproof effect of the device, and is suitable for the dynamic dustproof needs of the coal mine electromechanical equipment 100 during operation.

[0032] like Figures 1 to 3 As shown, in this embodiment, through the cooperation of the first clamping plate 54, the second clamping plate 55, and the first driving component 56, the dustproof structure 50 can be adjusted according to the dynamic changes in the equipment's operating status, ensuring that the dustproof curtain 53 is always in the optimal closed state. During the operation of the coal mining equipment, vibration may cause the dustproof curtain 53 to loosen, thereby reducing its dustproof effect. However, driven by the first driving component 56, even under severe equipment vibration, the dustproof curtain 53 can be tightly fitted, preventing dust from entering. This design is particularly suitable for the high-performance requirements of coal mining electromechanical equipment 100. For example, during deep mining, the equipment vibration is more severe, placing higher demands on the dustproof performance of the monitoring device. This design effectively addresses this challenge, ensuring that monitoring data is not interfered with by environmental factors, and providing a solid guarantee for the long-term stable operation of the coal mining equipment.

[0033] like Figures 1 to 3 As shown, in this embodiment, the first driving component 56 includes a first screw 561, and a protrusion 511 is provided on the top plate 51. The first screw 561 passes through the first clamping plate 54, the protrusion 511, and the second clamping plate 55. When the first screw 561 rotates, it can drive the first clamping plate 54 and the second clamping plate 55 to switch between a clamping state and a loosening state. The movement of the first clamping plate 54 and the second clamping plate 55 is realized by the rotation of the first screw 561. The operation is simple, the structure is stable, and the fixing state of the dust curtain 53 can be quickly adjusted. It is suitable for the rapid installation and disassembly of coal mine electromechanical equipment 100, improving the flexibility and working efficiency of the monitoring device.

[0034] like Figures 1 to 3As shown, in this embodiment, the design of the first screw 561 simplifies the fixing process of the dust curtain 53, enabling coal mine workers to quickly install and dismantle the monitoring device, greatly improving work efficiency. In underground coal mine operations, time is money; rapid installation and dismantling means the monitoring device can be quickly moved to different equipment or locations for monitoring, increasing the coverage and flexibility of equipment monitoring. Furthermore, the structural stability ensures that the dust curtain 50 will not be damaged due to improper operation during frequent installation and dismantling, extending the device's service life and reducing maintenance costs for coal mining enterprises.

[0035] like Figures 1 to 3 As shown, in this embodiment, the dustproof structure 50 also includes a guide rod 57, which passes through the first clamping plate 54, the protrusion 511, and the second clamping plate 55. The guide rod 57 ensures the straightness and stability of the first clamping plate 54 and the second clamping plate 55 during movement, avoiding the problem of the dustproof curtain 53 not being securely fixed due to the poor movement of the first clamping plate 54 and the second clamping plate 55. This is suitable for the high precision requirements of the dustproof structure 50 during vibration monitoring of the coal mine electromechanical equipment 100, ensuring the reliability of the monitoring data.

[0036] like Figures 1 to 3 As shown, in this embodiment, the addition of the guide rod 57 further enhances the stability and precision of the dustproof structure 50, ensuring that the first clamping plate 54 and the second clamping plate 55 do not shift during movement, thereby preventing the fixed state of the dustproof curtain 53 from being affected and ensuring the consistency of the dustproof effect. In the vibration monitoring of coal mine electromechanical equipment 100, a high-precision dustproof structure 50 is crucial to ensuring the accuracy of monitoring data. For example, when monitoring minor vibrations of the equipment, even a slight displacement of the dustproof curtain 53 can lead to recording errors. The precise design of the guide rod 57 effectively avoids such problems, ensuring reliable and accurate monitoring data under any circumstances, providing a solid foundation for precise equipment maintenance and troubleshooting.

[0037] like Figures 1 to 3 As shown, in this embodiment, a connecting block 22 is provided on the winding structure 20, and a connecting hole 221 is provided on the connecting block 22. The connecting rod 52 is inserted into the connecting hole 221. This connection method makes the connection between the winding structure 20 and the dustproof structure 50 more stable, and at the same time facilitates disassembly and maintenance. It is suitable for long-term vibration monitoring of coal mine electromechanical equipment 100, ensures stable winding of the recording paper 21, and improves the durability of the monitoring device.

[0038] like Figures 1 to 3As shown, in this embodiment, the combined design of the connecting block 22 and the connecting rod 52 simplifies the connection process between the winding structure 20 and the dustproof structure 50, making the installation and maintenance of the device more convenient. During the long-term operation of the coal mine electromechanical equipment 100, the stable winding of the recording paper 21 is crucial to ensuring the continuity of monitoring data. Through a robust connection method, even under severe equipment vibration, the recording paper 21 can remain flat and stably wound, avoiding data loss due to curling or breakage of the recording paper 21. This design is particularly suitable for continuous monitoring of coal mine equipment. For example, during continuous mining operations, vibration monitoring of the equipment needs to be conducted uninterrupted to ensure that the equipment operates in optimal condition. This design meets the needs of such continuous monitoring, improving the efficiency and accuracy of monitoring.

[0039] like Figures 1 to 3 As shown, in this embodiment, the vibration monitoring device further includes a support structure 60. The support structure 60 includes a fixing member 61 and an abutment block 62 movably mounted on the fixing member 61. The abutment block 62 abuts against the recording paper 21. The support structure 60 is located on the side of the recording paper 21 away from the recording pen. The addition of the support structure 60 ensures the flatness and stability of the recording paper 21 during vibration monitoring, avoiding the impact of recording paper displacement caused by equipment vibration on the monitoring results. It is suitable for vibration monitoring of coal mine electromechanical equipment 100 in high-vibration environments, improving the accuracy and reliability of monitoring data.

[0040] like Figures 1 to 3 As shown, in this embodiment, the introduction of the support structure solves the problem of keeping the recording paper flat under high vibration conditions. Through the contact between the movable abutment block 62 and the recording paper 21, the abutment force can be adjusted in real time, ensuring the stability of the recording paper 21 under any vibration conditions. This is particularly important for the precise vibration monitoring of coal mine electromechanical equipment 100. For example, when monitoring the cutting vibration of a coal mining machine, even slight vibration changes can affect the recording paper 21, leading to distortion of the monitoring data. Through the precise control of the support structure 60, displacement of the recording paper 21 can be effectively avoided, ensuring the authenticity and integrity of the monitoring data. This provides more accurate data support for the performance evaluation and fault diagnosis of coal mine equipment, helping coal mining enterprises achieve intelligent and refined equipment management.

[0041] like Figures 2 to 4 As shown, in this embodiment, the clamping structure 40 includes a mounting block 41, a clamping block 42, and a second driving member 43. The second driving member 43 is disposed between the mounting block 41 and the clamping block 42 to adjust the distance between them. This design makes the clamping of the recording pen more flexible, adaptable to different models of recording pens, and suitable for the diverse monitoring needs of coal mine electromechanical equipment 100, thus improving the versatility and adaptability of the monitoring device.

[0042] like Figures 2 to 4 As shown in this embodiment, the flexible design of the clamping structure 40 allows the vibration monitoring device to adapt to the different types of recording pens used in the coal mine electromechanical equipment 100. Whether it's a traditional ink pen or a modern digital pen, both can be stably clamped, ensuring the continuity and integrity of data recording. In coal mine equipment monitoring, different devices may require different models of recording pens to meet specific monitoring requirements. The versatility of the clamping structure 40 ensures that the vibration monitoring device maintains good working condition when changing recording pens, avoiding monitoring failures due to incompatible pen models. This design is particularly suitable for comprehensive monitoring of coal mine equipment. For example, when conducting equipment performance evaluation, it may be necessary to monitor multiple devices simultaneously, using different models of recording pens. This design meets such diverse monitoring needs, improving the adaptability and efficiency of the monitoring device.

[0043] like Figures 2 to 4 As shown, in this embodiment, the clamping structure 40 further includes a vertical rod 44 and a spring 45. A through hole is provided on the clamping block 42, the vertical rod 44 passes through the through hole and is connected to the mounting block 41, and the spring 45 is sleeved on the vertical rod 44 and abuts against the clamping block 42. The spring 45 provides a certain buffering effect, preventing excessive impact from equipment vibration on the recording pen. This is suitable for the protection needs of the recording pen during vibration monitoring of the coal mine electromechanical equipment 100, extending the service life of the recording pen and reducing maintenance costs.

[0044] like Figures 2 to 4 As shown, in this embodiment, the combined use of the upright 44 and the spring 45 provides effective vibration buffering for the recording pen, reducing the direct impact of equipment vibration on the recording pen and extending its service life. In underground coal mines, equipment vibration can not only affect the accuracy of monitoring data but also damage the recording pen, leading to recording interruptions. Through the buffering effect of the spring 45, the recording pen remains stable even under severe equipment vibration, avoiding recording interruptions or data distortion. This design is particularly suitable for the high-vibration environment of coal mine equipment. For example, when monitoring the vibration of a hoist, the operation of the hoist generates significant vibrations, placing high demands on the protection of the recording pen. This design effectively protects the recording pen, ensures the continuity and reliability of monitoring data, reduces maintenance costs for coal mining enterprises, and improves the safety and economic efficiency of equipment operation.

[0045] like Figures 2 to 4As shown, in this embodiment, the transmission structure 30 includes a first transmission plate 31, a second transmission plate 32, and a locking member 33. The first transmission plate 31 has a mounting groove 311, and the first end of the second transmission plate 32 is installed in the mounting groove 311. A clamping structure 40 is disposed at the second end of the second transmission plate 32, and the locking member 33 is disposed between the mounting groove 311 and the first end of the second transmission plate 32. This transmission structure 30 design ensures a stable connection between the vibration monitoring device and the coal mine electromechanical equipment 100. The use of the locking member 33 further improves the reliability of the connection. It is suitable for vibration monitoring of the coal mine electromechanical equipment 100 during operation, ensuring the continuity and integrity of the monitoring data and providing strong support for equipment maintenance.

[0046] like Figures 2 to 4 As shown, in this embodiment, through the combined design of the first transmission plate 31, the second transmission plate 32, and the locking member 33, the vibration monitoring device can form a stable connection with the coal mine electromechanical equipment 100. Even if severe vibrations occur during equipment operation, the vibration monitoring device will not shift, ensuring the continuity and integrity of the monitoring data. The use of the locking member 33 further enhances the connection strength between the vibration monitoring device and the equipment, avoiding monitoring failures due to weak connections. In the maintenance of coal mine equipment, such continuous and complete monitoring data is crucial for assessing equipment status and predicting faults. For example, when monitoring the operating status of a conveyor, the long-term operation of the conveyor will produce various minute vibration changes, which may indicate potential equipment faults. Through continuous monitoring, coal mining enterprises can promptly detect these changes, take preventive measures, avoid equipment failures, reduce unplanned downtime, and improve the efficiency and safety of coal mine production.

[0047] In summary, the vibration monitoring device provided in this application, through its unique design, can not only record and monitor the vibration of the coal mine electromechanical equipment 100 in real time, but also effectively address dust and vibration issues in the coal mine environment, improving the accuracy and reliability of the monitoring data. Simultaneously, the flexibility and versatility of the vibration monitoring device enable it to adapt to the diverse monitoring needs of the coal mine electromechanical equipment 100, making it particularly suitable for vibration monitoring in various complex environments underground, such as coal mining faces, roadway transportation, and hoisting systems. This provides crucial information for the maintenance and fault prediction of coal mine equipment, effectively improving the safety and efficiency of equipment operation. Furthermore, the rapid installation and disassembly characteristics of the vibration monitoring device allow it to play a vital role in both regular inspections and temporary monitoring of coal mine equipment, reducing the difficulty and cost of equipment maintenance and demonstrating broad application prospects and market potential.

[0048] In this embodiment, the dustproof curtain 53 on the outside of the top plate 51 can protect and cover the winding structure 20 and the clamping structure 40, reducing the proximity of surrounding dust when the winding structure 20 is working. This prevents dust from affecting the monitoring and recording effect when the winding structure 20 is monitoring and recording. When observation is needed, it can be observed through the dustproof curtain 53. Alternatively, the top plate 51 and the dustproof curtain 53 can be lifted for observation using the pull ring on the top plate 51. If the dustproof curtain 53 is damaged, the first clamping plate 54 and the second clamping plate 55 can be moved away from each other by the first driving member 56, making it easy to remove the dustproof curtain 53 and replace it. Recording paper 21 is sleeved on the surface of the winding structure 20, and one side of the recording paper 21 is attached to the winding structure 20. With the output end connected, the vibration monitoring device can conveniently record vibrations on the recording paper 21. The top plate 51 can be quickly connected to the winding structure 20 for protection by inserting the connecting rod 52 into the connecting hole 221. During recording, the recording pen can be clamped on the clamping structure 40, and the clamping block 42 can be pressed by the spring 45, so that the clamping block 42 presses against the recording pen. When the coal mine electromechanical equipment 100 uses vibration, the vibration can be transmitted through the transmission structure 30. The vibration range is recorded on the recording paper 21 by the recording pen, and the winding structure 20 can be wound up at the same time to complete the monitoring and recording. The second driving member 43 can be rotated to drive the clamping block 42 and the second driving member 43 to better clamp the recording pen.

[0049] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0050] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
