[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0022] like Figures 1 to 2As shown, this utility model provides a vibration fault early warning device for coal mine electromechanical equipment, including a left support plate 11 and a right support plate 12. The left support plate 11 and the right support plate 12 are the main supporting carriers of the entire early warning device. They cooperate with each other to provide installation space for other components and maintain the overall structural stability of the device. A retaining frame 17 is provided at one end of both plates to connect and secure the detection components. The retaining frame 17 is fixedly connected to the left support plate 11 and the right support plate 12 respectively by bolts, ensuring a firm connection between the retaining frame 17 and the support plate and enabling it to withstand various forces generated during detection. Detection receiving columns 18 are provided on multiple retaining frames 17, one end of which is threadedly connected to the retaining frame 17. This arrangement facilitates installation and disassembly and allows adjustment of the installation angle and position of the detection receiving columns 18 as needed. The detection receiving columns 18 are used to accommodate and guide the movement of the detection block 19 and the vibration spring column 19, providing them with a movement track and support. Vibration spring columns 19 are installed on multiple detection receiving columns 18, with one end slidably connected to the detection receiving column 18 and the other end having an anti-detachment protrusion. This ensures that the vibration spring column 19 slides smoothly within the detection receiving column 18 while preventing it from detaching. The vibration spring column 19 buffers and transmits vibrations. When the coal mine electromechanical equipment vibrates, the vibration spring column 19 senses the vibration and transmits it to the detection abutment block 19. The vibration frequency is transmitted through its own elastic deformation, and the energy generated by the impact reaches the detection abutment block 19, ensuring accurate and stable detection. Detection abutment blocks 19 are also installed on the multiple detection receiving columns 18, slidably connected to the detection receiving column 18. One end of the detection abutment block 19 has a vibration sensing block 19. Under the vibration transmitted by the vibration spring column 19, the detection abutment block 19 moves back and forth within the detection receiving column 18, driving the vibration sensing block 19 to sense the vibration. Both the detection block 19 and the detection receiving column 18 have position fixing holes and multiple limiting posts 21 on the holes. By adjusting the position of the limiting posts 21 in the position fixing holes, the movement range of the detection block 19 can be limited, and the detection sensitivity of the detection block 19 can be adjusted according to the different vibration characteristics of the coal mine electromechanical equipment. Multiple detection blocks 19 are connected to the vibration receiving instrument body 14, which can transmit the vibration information sensed by the vibration sensing block 19 to the vibration receiving instrument body 14, providing data for subsequent vibration analysis and early warning. The placement box 13 on the right support plate 12 is used to hold the vibration receiving instrument body 14. The placement box 13 is fitted with a soft pad 24, which can buffer the external impact force and prevent the vibration receiving instrument body 14 from being damaged by the device itself or external vibration. The soft pad 24 has an instrument placement frame 25, and the vibration receiving instrument body 14 is secured to the instrument placement frame 25. The instrument placement frame 25 is connected to the soft pad 24 by bolt plates, which not only ensures that the vibration receiving instrument body 14 is placed stably, but also facilitates disassembly during maintenance or instrument replacement. The vibration receiving instrument body 14 is the core detection component of the early warning device. It receives vibration information transmitted from the detection block 19, analyzes and processes it, and transforms the vibration data into a recognizable signal to provide a basis for subsequent display and early warning.The cover plate 15 on the placement box 13 engages with the placement box 13, protecting the vibration receiving instrument body 14 inside the placement box 13 from damage caused by external factors such as dust and moisture. The display 16 on the cover plate 15 is electrically connected to the vibration receiving instrument body 14, displaying the vibration data analyzed and processed by the vibration receiving instrument body 14 in real time, allowing operators to clearly see the vibration status of the coal mine's electromechanical equipment. The cover plate 15 also has an indicator light 25, which is also electrically connected to the vibration receiving instrument body 14. When the vibration receiving instrument body 14 detects vibration data exceeding a preset threshold, the indicator light 25 illuminates, visually reminding operators of potential vibration malfunctions in the equipment. The left support plate 11 has a sliding groove, and one end of the right support plate 12 has a protrusion. The protrusion and the sliding groove are slidably connected, allowing the relative positions of the left and right support plates 11 and 12 to be adjusted. The device includes a protrusion and multiple adjustment holes, as well as limiting connecting posts 23 passing through these holes. After adjusting the relative positions of the left and right bearing plates, the limiting connecting posts 23 are used for fixation, meeting the installation needs of coal mine electromechanical equipment of different sizes and improving the device's versatility and adaptability. Both the left bearing plate 11 and the right bearing plate 12 have mounting plates 26 on one side. Multiple mounting plates 26 are connected to the left and right bearing plates 11 and 12 via multiple limiting connecting posts 23, facilitating the disassembly and replacement of the mounting plates 26. Each mounting plate 26 has a fixing connecting block 27, which is used to fix the entire early warning device in a specific position on the coal mine electromechanical equipment, ensuring that the device does not shift due to vibration or shaking during equipment operation, thus ensuring accurate and stable detection. Both the left and right bearing plates 11 and 12 have guide plates 22 at one end, which serve as guides during installation, allowing operators to quickly and accurately align and connect the left and right bearing plates 11 and 12, improving installation efficiency.

[0023] like Figures 2 to 4As shown, when using the device, the left support plate 11 and the right support plate 12 are placed in their respective positions on the coal mine electromechanical equipment. The left support plate 11 and the right support plate 12 cooperate to form the main support structure of the entire early warning device, supporting all components and ensuring the device remains stable during operation of the coal mine electromechanical equipment, preventing it from easily shifting or being damaged due to equipment vibration, thus providing a fundamental guarantee for the smooth operation of the entire early warning work. The placement box 13, fixed to the right support plate 12, provides a safe placement space for the vibration receiving instrument body 14. The placement box 13 acts as a protective container, housing the vibration receiving instrument body 14 and protecting it from external interference. Once placed in the placement box 13, the vibration receiving instrument body 14 begins detection. It is constantly ready to receive vibration information transmitted by the detection block 19, analyze and process this information, and convert the vibration state of the equipment into data signals that can be identified and judged, providing crucial information for subsequent early warning operations. The cover plate 15 on the placement box 13 is snapped into place. It serves two purposes: firstly, it prevents common underground coal mine contaminants such as dust and moisture from entering the placement box 13, protecting the vibration receiving instrument body 14 from corrosion; secondly, the display 16 on the cover plate 15 is electrically connected to the vibration receiving instrument body 14, displaying the vibration data analyzed and processed by the instrument body 14 in real time. By observing the display 16, operators can intuitively understand the vibration status of the coal mine's electromechanical equipment and promptly detect potential vibration faults. Simultaneously, the cover plate 15 also has an indicator light 25, which is also electrically connected to the vibration receiving instrument body 14. When the vibration data detected by the vibration receiving instrument body 14 exceeds a preset threshold, the indicator light 25 will immediately illuminate, conspicuously alerting the operator to the potential vibration fault and prompting timely action. The abutment fixing frames 17 at one end of both the left and right support plates 11 and 12 play a crucial role in connecting and stabilizing the detection components. The abutment fixing frame 17 is fixedly connected to the left bearing plate 11 and the right bearing plate 12 respectively by bolts. This arrangement ensures the stability between the abutment fixing frame 17 and the bearing plate, enabling it to withstand various forces generated during the testing process. Each of the multiple abutment fixing frames 17 is equipped with a detection receiving column 18, one end of which is threadedly connected to the abutment fixing frame 17. This arrangement facilitates installation and disassembly, and allows adjustment of the installation position of the detection receiving column 18 according to actual needs. The detection receiving column 18 is mainly used to accommodate and guide the movement of the detection abutment block 19 and the vibration spring column 19, providing them with a movement track and support. The vibration spring column 19, installed on the multiple detection receiving columns 18, has one end slidably connected to the detection receiving column 18, and its other end is equipped with an anti-detachment protrusion. This ensures smooth sliding of the vibration spring column 19 within the detection receiving column 18 while preventing it from detaching from the detection receiving column 18.The vibration spring column 19 serves to buffer and transmit vibration. When the coal mine electromechanical equipment vibrates, the vibration spring column 19 senses the vibration and transmits it to the detection block 19. Simultaneously, its elastic deformation buffers part of the vibration energy, preventing damage to the detection block 19 due to excessive instantaneous impact, thus ensuring the accuracy and stability of the detection. Multiple sets of detection receiving columns 18 are also equipped with detection blocks 19, which are slidably connected to the detection receiving columns 18. One end of each detection block 19 has a vibration sensing block 19. Under the vibration transmitted by the vibration spring column 19, the detection block 19 reciprocates within the detection receiving column 18, thereby driving the vibration sensing block 19 to sense the vibration. Both the detection block 19 and the detection receiving column 18 are provided with position fixing holes and multiple sets of limiting columns 21 on the holes. By adjusting the position of the limiting columns 21 in the position fixing holes, the movement range of the detection block 19 can be limited, thereby adjusting the detection sensitivity of the detection block 19 according to the vibration characteristics of different coal mine electromechanical equipment. Multiple sets of detection blocks 19 are connected to the vibration receiving instrument body 14, enabling the transmission of vibration information sensed by the vibration sensing blocks 19 to the vibration receiving instrument body 14, providing a data basis for subsequent vibration analysis and early warning. A sliding groove is provided on the left support plate 11, and a protrusion is provided at one end of the right support plate 12. The protrusion is slidably connected to the sliding groove, allowing the relative position between the left support plate 11 and the right support plate 12 to be adjusted. Multiple sets of adjustment holes on the protrusion, and limiting connecting posts 23 passing through these adjustment holes, allow the left and right support plates to be fixed in position after their relative positions are adjusted, thereby meeting the installation requirements of coal mine electromechanical equipment of different sizes and improving the versatility and adaptability of the device.

[0024] The specific usage and function of this embodiment are as follows:

[0025] When using this device, the user first slides the protrusion at one end of the right support plate 12 into the groove of the left support plate 11. After adjusting the positions of the two according to the actual dimensions of the installation location, the user fixes them with the limiting connecting column 23 to complete the main structure construction to adapt to different installation spaces. Next, the abutment fixing frame 17 is fixed to one end of the left support plate 11 and the right support plate 12 with bolts. The detection receiving column 18 is threaded to the abutment fixing frame 17 and the angle is adjusted as needed. The vibration spring column 19 with anti-detachment protrusion is placed in, and then the detection abutment 19 that can slide in the detection receiving column 18 is installed. One end of the detection abutment is connected to the vibration sensing block 19. The detection sensitivity is adjusted by the position of the fixing hole of the limiting column 21. After that, the soft pad 2 is placed in the box 13 of the right support plate 12. 4. Connect the instrument placement frame 25 to the soft pad 24 with bolt plates and insert them into the vibration receiving instrument body 14 for secure installation and protection. Secure the cover plate 15 to the placement box 13, so that the display 16 and the warning light 25 are electrically connected to the vibration receiving instrument body 14 respectively. After the device is installed on the equipment, the equipment vibration is transmitted to the vibration spring column 19, which then transmits it to the detection block 19 to drive the vibration sensing block 19 to sense the vibration information and transmit it to the vibration receiving instrument body 14. The data after analysis and processing is displayed on the display 16 in real time. When the vibration data exceeds the preset threshold, the warning light 25 lights up to remind the user that the equipment may have a vibration fault, so that timely measures can be taken to prevent equipment failure and ensure the safe and stable operation of coal mine electromechanical equipment.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
