[0002] In coal mining, roadway cross-sectional shapes commonly include rectangular, trapezoidal, and arched forms. Design must comprehensively consider geological conditions, production needs, support methods, and safety factors to optimize space utilization and construction efficiency. Accurate measurement data is crucial for ensuring mine safety and improving production efficiency during the development and maintenance phases of underground roadways. However, traditional measuring tools and techniques are often limited by harsh environmental factors such as confined spaces, insufficient lighting, and poor ventilation, resulting in low data acquisition efficiency and difficulty in guaranteeing accuracy. Furthermore, complex terrain and unstable geological conditions also pose challenges to conventional measuring equipment. Therefore, a foldable rapid cross-sectional mapping instrument for underground coal mine roadways is urgently needed.

[0003] Currently, existing foldable rapid cross-section surveying instruments for underground coal mine roadways are usually measured by construction personnel using handheld surveying instruments. This makes it difficult to avoid errors and instability caused by manual operation. Furthermore, existing rapid cross-section surveying instruments cannot repeatedly survey the same cross-section, increasing the error of a single measurement. They also cannot dynamically monitor the deformation of the roadway during construction, thus failing to compare measurement data from different time periods. Utility Model Content

[0021] Please see Figure 1-4 This utility model provides a technical solution: a foldable rapid cross-section mapping instrument for underground coal mine roadways, including a roadway body 1. A guide rail 2 is provided on one side of the inner wall of the roadway body 1. One side of the guide rail 2 is connected and fixed to the roadway body 1 by a fixing bolt 3. A sliding plate 4 adapted to the guide rail 2 is slidably connected to it. A gear 5 adapted to the gear 4 is provided inside the sliding plate 4. The input end of the gear 5 is connected to the output end of the motor 6. The motor 6 is connected and fixed to the sliding plate 4 by a fastening bolt 7. A tooth groove 8 adapted to the gear 5 is provided on the other side of the guide rail 2. The tooth surface of the tooth groove 8 is connected to the tooth surface of the gear 5. A symmetrically distributed support rod 9 is provided on one side of the motor 6. A shock-absorbing component 10 is connected to the top of the support rod 9. The shock-absorbing component 10 includes... The system includes a fixed plate 101, which is connected and fixed to the support rod 9 via a knob 102. Symmetrically distributed X-shaped brackets 103 are provided on both sides of the fixed plate 101. One side of each X-shaped bracket 103 is connected and fixed to the fixed plate 101 via a movable pin 104. Damping shock absorbers 105 are provided on opposite sides of each X-shaped bracket 103. During surveying, the motor 6 drives the gear 5 to move the slider along the guide rail 2, ensuring the surveyor moves stably and accurately along the tunnel cross-section quickly, thus avoiding errors and instability caused by manual operation. Furthermore, the guide rail 2 allows for repeated surveying of the same cross-section, reducing errors in single measurements. It also enables dynamic monitoring of tunnel deformation during construction and comparison of measurement data from different time periods.

[0022] One end of the damping shock absorber 105 is connected to the top of the fixed plate 101 via a movable pin 104. The other side of the two X-shaped brackets 103 is provided with a mounting plate 106. The other end of the damping shock absorber 105 is connected to the bottom of the mounting plate 106 via a movable pin 104. The main body of the surveying instrument 11 is provided on one side of the mounting plate 106. The main body of the surveying instrument 11 is connected and fixed to the mounting plate 106 by a fastening ring 12 and a matching mounting bolt 13. When the surveying instrument moves to conduct surveying, the vibration and impact received by the surveying instrument are absorbed and buffered by the elastic deformation of the X-shaped brackets 103 in the shock absorption assembly 10 and the action of the damping shock absorber 105, thereby avoiding errors in measurement accuracy.

[0023] Working Principle: During surveying, motor 6 drives gear 5 to move the slider along guide rail 2, ensuring the surveyor moves stably and accurately along the tunnel cross-section quickly, thus avoiding errors and instability caused by manual operation. Furthermore, the guide rail 2 allows for repeated surveying of the same cross-section, reducing errors in single measurements. It also allows for dynamic monitoring of tunnel deformation during construction, comparing measurement data from different time periods. When the surveyor moves, the elastic deformation of the X-shaped bracket 103 within the shock-absorbing component 10 and the damping shock absorber 105 absorb and buffer the vibrations and impacts on the surveyor, preventing errors in measurement accuracy. This completes the operation process of a foldable rapid cross-section surveyor for underground coal mine tunnels.
