Description

Technical Field

[0001] This utility model relates to the field of original rock grade detection technology, and in particular to a coal mine original rock grade detection device. Background Technology

[0002] In the coal mining industry, accurately detecting the original rock grade of a coal mine is crucial for ensuring the safety and efficiency of mining operations. Determining the original rock grade provides key information for the formulation of mining plans, support design, and equipment selection.

[0003] Existing coal mine original rock grade detection equipment typically uses threaded connections for its extension pipe. In the complex geological environment of underground coal mines, the original rock fissures have diverse shapes and often include slightly curved fissures. Due to structural limitations, existing threaded extension pipes can only extend straight into the fissures for detection. Once they encounter slightly curved fissures, the extension pipe cannot extend smoothly, making it impossible to detect the original rock in these areas. This results in the omission of important geological information and affects the comprehensive and accurate assessment of the original rock grade. Therefore, improvements are needed to address these issues. Utility Model Content

[0018] 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.

[0019] Example: See Figure 1-4 This utility model discloses a coal mine raw rock grade detection device, comprising an ultrasonic probe 1. The top of the ultrasonic probe 1 is provided with a first external threaded cylinder 2, and a first extension tube 3 is threadedly connected to the first external threaded cylinder 2. One end of the first extension tube 3 is provided with a second extension tube 4. A connecting assembly is provided between the second extension tube 4 and the first extension tube 3. The threaded connection between the first external threaded cylinder 2 at the top of the ultrasonic probe 1 and the first extension tube 3 allows for flexible adjustment of the installation position of the first extension tube 3 according to the actual detection depth requirements, thereby changing the length of the entire detection device. This facilitates the detection of coal mine raw rock at different depths. The second extension tube 4 further increases the adjustability of the device. The presence of the connecting assembly provides a basis for the connection between the first extension tube 3 and the second extension tube 4, ensuring the structural stability of the device after length adjustment. One end of the second extension tube 4 is threadedly connected to a handheld cylinder 5, and a handle is provided on one side of the upper end of the handheld cylinder 5. The second extension tube 4 is threadedly connected to the handheld cylinder 5. This design allows the handheld tube 5 to be securely mounted on the detection device, making it easy for operators to hold. The handle on the handheld tube 5 is ergonomically designed to effectively reduce hand fatigue and improve operational comfort and convenience. This allows operators to more stably control the detection device for detection work. Two data cables 6 extend from the ultrasonic probe 1, passing through the second extension tube 4, the first extension tube 3, and the handheld tube 5. The ends of the two data cables 6 are plugged into the control host 7. The original rock data detected by the ultrasonic probe 1 is transmitted through the two data cables 6, which pass through the second extension tube 4, the first extension tube 3, and the handheld tube 5 and are plugged into the control host 7. This design ensures the rationality and security of the data transmission path, reduces the possibility of external interference and damage to the data cables 6 during transmission, and thus enables accurate and timely transmission of detection data to the control host 7 for analysis and processing, improving the efficiency and reliability of data transmission.

[0020] In this invention, the connecting assembly includes two hinge seats 8 symmetrically installed on both sides of the top end of the first extension tube 3. A C-shaped frame 11 is fixedly connected to the rotation axis of the two hinge seats 8. A corresponding locking seat 9 is provided on the second extension tube 4. The hinge seats 8 on both sides of the top end of the first extension tube 3 are fixedly connected to the C-shaped frame 11, allowing the C-shaped frame 11 to rotate around the rotation axis of the hinge seats 8. The locking seat 9 on the second extension tube 4 corresponds to and engages with the C-shaped frame 11. When encountering slightly curved coal mine rock fissures, the angle of the second extension tube 4 can be adjusted by rotating the C-shaped frame 11, allowing the second extension tube 4 to smoothly extend into the fissure for detection. This greatly improves the adaptability of the detection device to complex fissure environments and expands the detection range. A soft rubber protective sleeve 10 is provided on the inner wall of the second extension tube 4. The bottom end of the soft rubber protective sleeve 10 is inserted into the upper end of the inner wall of the first extension tube 3. The soft rubber protective sleeve 10 on the inner wall of the second extension tube 4 is inserted into the upper end of the inner wall of the first extension tube 3, enabling… The soft rubber protective sleeve 10 effectively protects the internal components, such as the data cable 6 passing through it. It can buffer external impact and friction, preventing the data cable 6 from being worn or broken. At the same time, it can also play a certain role in dust prevention and moisture prevention, extending the service life of the internal components of the device and improving the reliability and stability of the detection device. The C-shaped frame 11 is divided into two symmetrically arranged C-shaped plates. A snap-fit ​​post is inserted between the opposite surfaces of the two C-shaped plates. The snap-fit ​​seat 9 is provided with a snap-fit ​​groove corresponding to the snap-fit ​​post. A rubber stop 12 is provided at the snap-fit ​​interface of the snap-fit ​​groove. The two C-shaped plates of the C-shaped frame 11 are connected by snap-fit ​​posts and cooperate with the snap-fit ​​groove on the snap-fit ​​seat 9 to achieve a firm connection between the first extension tube 3 and the second extension tube 4. The rubber stop 12 at the snap-fit ​​interface of the snap-fit ​​groove can prevent the snap-fit ​​post from loosening or falling off during use, further enhancing the stability of the connection and ensuring the structural stability of the detection device during the detection process, avoiding the impact of loose connection on the accuracy of the detection results.

[0021] Working principle: When using this utility model, firstly, the first extension tube 3 is installed on the first external threaded cylinder 2 at the top of the ultrasonic probe 1 by means of a threaded connection. Then, the second extension tube 4 is connected to the first extension tube 3 by means of a connecting assembly. Specifically, the C-shaped frame 11 (composed of two symmetrically arranged C-shaped plates with a snap-fit ​​post in the middle) is installed on both sides of the top of the first extension tube 3 by means of a hinge seat 8. Then, the snap-fit ​​seat 9 on the second extension tube 4 is aligned with the C-shaped frame 11, so that the snap-fit ​​post is snapped into the snap-fit ​​groove of the snap-fit ​​seat 9. The rubber stop 12 at the snap-fit ​​groove interface ensures that the snap-fit ​​post is firmly snapped into the groove, thus completing the connection between the first extension tube 3 and the second extension tube 4. Then, the handheld cylinder 5 is installed on one end of the second extension tube 4 by means of a threaded connection to ensure a firm connection. Finally, the two data cables 6 extending from the ultrasonic probe 1 are passed through the second extension tube 4, the first extension tube 3 and the handheld cylinder 5 in sequence. Then, the ends of the data cables 6 are plugged into the control host 7 to complete the arrangement of the data transmission line, ensuring that the data detected by the ultrasonic probe 1 can be successfully transmitted to the control host 7 for processing.
