[0001] This utility model relates to the field of mine monitoring equipment technology, specifically to an installation structure for a mine pressure transmitter sensor. Background Technology

[0002] In mining operations, pressure monitoring of the underground environment is a crucial aspect of ensuring safe production. Mining pressure transmitters, as key monitoring equipment, are widely used in electro-hydraulic control systems for coal mine hydraulic supports, roadway support systems, and other applications. These sensors can monitor and transmit pressure data in real time, helping managers understand changes in the underground environment and take appropriate safety measures.

[0003] In practical applications, existing mine pressure transmitter sensors are often installed using simple threaded connections or clips. This structure is prone to loosening due to vibration and impact during long-term use, which affects the measurement accuracy and service life of the sensor. At the same time, due to the complex and variable underground environment, the sensor needs to be frequently operated during installation and disassembly. The existing installation structure is not convenient enough, which increases the difficulty and time cost for maintenance personnel. Utility Model Content

[0004] The purpose of this invention is to provide an installation structure for a mine pressure transmitter sensor, in order to solve the problem mentioned in the background art that the current installation method of mine pressure transmitter sensors is prone to loosening due to vibration and impact during long-term use, which affects the measurement accuracy and service life of the sensor.

The outer side of the mounting base is provided with a sleeve for installing the sensor body. The sleeve is symmetrically provided with telescopic clamping members inside. Both sides of the sleeve and the mounting base are provided with vibration isolation and buffering assemblies composed of a balance plate, a support shaft, and a vibration isolation ring. The bottom outer side of the mounting base is provided with an inner clamping member, and the outer side of the inner clamping member is provided with a stretchable outer clamping member.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4, the present utility model provides a technical solution: an installation structure of a mine pressure变送 sensor, including a sensor body 1 and an installation base 2. The installation base 2 is of a "U" - shaped structure and installation holes are provided at all four corners. A sleeve 3 for installing the sensor body 1 is provided on the outer side of the installation base 2. Symmetric telescopic clamping members 6 are provided inside the sleeve 3. Vibration isolation and buffering components composed of a balance plate 4, a support shaft 5 and a vibration isolation ring 11 are provided between both sides of the sleeve 3 and the installation base 2. And an inner clamping member 7 is provided at the outer bottom end of the installation base 2. An extendable outer clamping member 8 is provided outside the inner clamping member 7. The inner clamping member 7 and the outer clamping member 8 are horizontally distributed front and back. The inner clamping member 7 and the outer clamping member 8 together form a dynamic adjustment and stabilization component. In this structure, the sleeve 3 automatically adapts to different diameters of the sensor body 1 through the elastic deformation ability of the telescopic clamping members 6 to ensure its firm fixation. At the same time, when subjected to external vibration or impact, the balance plate 4 and the support shaft 5 work together to transmit the vibration energy to the vibration isolation ring 11. The vibration isolation ring 11 effectively absorbs and disperses this energy, reducing the vibration transmitted to the sensor body 1. The inner clamping member 7 and the outer clamping member 8 can cooperate with each other to enhance the clamping force when installing the sensor body 1, making the whole structure highly stable even in a harsh environment. Generally speaking, this not only improves the anti - vibration performance of the sensor body 1, but also simplifies the installation and disassembly processes, greatly reducing the work difficulty and time cost of maintenance personnel, solving the loosening problem caused by simple threaded connection or snap - fixing methods in the prior art and the inconvenience caused by frequent operations in the complex underground environment, effectively improving the maintenance efficiency and equipment reliability. The balance plate 4 is welded and fixed on both sides of the outer wall of the sleeve 3. Both the upper and lower ends of the support shaft 5 penetrate through the balance plate 4 and are welded and fixed at the connection with the outer wall of the installation base 2. The vibration isolation ring 11 is sleeved outside the connection between the upper and lower ends of the support shaft 5 and the installation base 2. In this structure, when the installation base 2 is subjected to external vibration or impact, it will be transmitted to the sensor body 1 through the sleeve 3. The sleeve 3 synchronously enables the balance plate 4 to move slightly up and down along the support shaft 5. This allows the balance plate 4 to generate an appropriate displacement when受力 to absorb part of the energy. At the same time, the vibration isolation ring 11 can effectively isolate and absorb the vibration energy transmitted from the support shaft 5, reducing the vibration directly transmitted to the sensor body 1. An elastic support pad 10 is also adhesively fixed on the outer wall of the installation base 2. The elastic support pad 10 is made of high - damping rubber material, and a recessed opening that coincides with the arc structure of the outer wall of the sleeve 3 is provided on the outer side of the elastic support pad 10. In this structure, the sleeve 3 can be firmly fitted on the elastic support pad 10 to form a tight fit. In this case, the elastic support pad 1也起到缓冲作用,吸收并分散由安装基座2传递过来的震动能量,内夹紧件7和外夹紧件8的两端均通过定位轴9与安装基座2相连接,且内夹紧件7的两端通过螺丝固定套设在定位轴9的外部,并且外夹紧件8的两端均活动套设在定位轴9的外部, It should be noted that there seems to be some incomplete or unclear expressions in the original Chinese text, such as "受力" which is not a complete word in this context. The translation is done as accurately as possible based on the existing text.A tension spring 12, sleeved on the outside of the positioning shaft 9, connects the inner clamping member 7 and the outer clamping member 8 at both ends. The inner clamping member 7 and the outer clamping member 8 have arc-shaped sections with corresponding opening directions in the middle. When installing or removing the sensor body 1, this structure allows the outer clamping member 8 to slide along the positioning shaft 9 by pulling it, thereby increasing the distance between the inner clamping member 7 and the outer clamping member 8, facilitating the insertion or removal of the sensor body 1. After releasing the outer clamping member 8, the tension spring 12 automatically retracts, causing the inner clamping member 7 and the outer clamping member 8 to fit tightly against the sensor body 1, providing a stable clamping force. This allows for flexible adjustment according to the actual size of the sensor body 1. This design not only ensures the robustness and stability of the sensor body 1 after installation, but also greatly simplifies the installation and disassembly process, reducing the operational difficulty and time cost for maintenance personnel. The telescopic clamping component 6 has an overall arc-shaped structure with its upper and lower ends extending to the outside of the sleeve 3. The telescopic clamping component 6 is connected to the inner wall of the sleeve 3 via an elastic compression pad made of high-elasticity sponge. With this structure, when the sensor body 1 is inserted into the sleeve 3, the telescopic clamping component 6 can automatically adjust its clamping force according to the external dimensions of the sensor body 1 under the force of the elastic compression pad, thus ensuring sufficient clamping force while avoiding damage to the sensor body 1.

[0019] Working principle: When using the installation structure of this mine pressure transmitter sensor, first, fix the entire device to the predetermined position through the mounting holes at the four corners of the mounting base 2. Then, pull the outer clamping member 8 to slide it along the positioning shaft 9, increasing the distance between the inner clamping member 7 and the outer clamping member 8, which facilitates the insertion of the sensor body 1. Then, insert the sensor body 1 into the sleeve 3, so that the telescopic clamping member 6 fits tightly against the outer dimensions of the sensor body 1 under the action of the elastic compression pad, until the bottom part of the sensor body 1 is placed between the inner clamping member 7 and the outer clamping member 8. When the outer clamping member 8 is released, the tension spring 12 will automatically retract, causing the inner clamping member 7 and the outer clamping member 8 to fit tightly against the sensor body 1, providing a stable clamping force. Subsequently, the sleeve 3 fits firmly against the elastic support pad 10, forming a tight fit. When external vibration or impact acts on the mounting base 2, the balance plate 4 can move slightly up and down along the support shaft 5, and work with the vibration isolation ring 11 to absorb and disperse this energy, reducing the vibration transmitted to the sensor body 1, ensuring the stability and measurement accuracy of the sensor body 1, thereby completing a series of tasks.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
