Description

Technical Field

[0001] This utility model relates to the technical field of underground roadway excavation measurement in coal mines, specifically a mobile underground roadway excavation measurement device. Background Technology

[0002] In the design of mine tunnel development and mining engineering, there are clear regulations and requirements for geometric elements such as the starting point, ending point, direction, slope, and cross-sectional specifications of the tunnel. Underground surveying in coal mines is a crucial link in achieving safe production during mine construction. It is an important and rigorous technical task and a vital means for coal mines to improve production technology management and achieve safe production. During the horizontal advancement of the tunnel, surveyors typically use laser measuring instruments to measure the displacement changes of the tunnel roof strata. However, the high dust concentration in underground coal mine tunnels causes dust to adhere to the detection end or optical element surface of the rangefinder, scattering and attenuating the laser beam's transmission path. This weakens the reflected light intensity, affecting the ranging accuracy and even causing data erratic readings or false alarms. Therefore, there is an urgent need for a mobile tunneling surveying device for coal mines.

[0003] Currently, existing mobile tunneling measurement devices for underground coal mine roadways cannot effectively remove dust, stains, and other impurities from the surface of the laser emission window, thus failing to keep the window clean and making it difficult to guarantee the accuracy of laser ranging. Furthermore, existing tunneling measurement devices may cause scratch damage when directly contacting the surface of the laser emission window during cleaning. Utility Model Content

[0004] The purpose of this utility model is to provide a mobile tunneling measurement device for underground coal mine roadways, in order to solve the problems mentioned in the background art, such as the inability of existing mobile tunneling measurement devices for underground coal mine roadways to effectively remove dust, stains and other impurities from the surface of the laser emission window, thus failing to keep the window clean and making it difficult to guarantee the accuracy of laser ranging, and the potential scratch damage caused by direct contact with the surface when cleaning the laser emission window.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile tunneling and measuring device for underground coal mine roadways, comprising a measuring body, wherein a dust scraping component is provided on the laser emission window of the measuring body, the dust scraping component includes a fixing ring, a slide rail is provided on the inner wall of the fixing ring, and symmetrically distributed sliders are provided inside the slide rail, the inner walls of the two sliders are respectively connected to the two ends of a scraper, and the scraper is slidably connected to the fixing ring through the slider and the slide rail.

[0006] Preferably, the scraper is adapted to the laser emission window of the measuring body, and a cleaning cotton adapted to it is provided on the side of the scraper that is in contact with the laser emission window. The outer walls of the two sliders are connected to the inner walls of the transmission wheel adapted to the fixing ring.

[0007] Preferably, the outer wall of the transmission wheel is provided with a gear groove, the tooth surface of the gear groove is connected to the tooth surface of the drive wheel that is adapted to it, and the input end of the drive wheel is connected to the output end of the micro motor.

[0008] Preferably, the micro motor, the drive wheel, and the transmission wheel are respectively disposed inside the retaining ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This mobile tunneling and measuring device for underground coal mine roadways can drive a drive wheel to rotate via a micro motor when it is necessary to clean the dust from the laser emission window. This, in turn, causes the slider to rotate the scraper. Simultaneously, the cleaning cotton effectively removes dust, stains, and other impurities from the laser emission window surface, thus maintaining the window's cleanliness and ensuring the accuracy of laser ranging. Furthermore, the cleaning cotton acts as a buffer between the scraper and the laser emission window, reducing potential scratches caused by direct contact between the scraper and the window surface.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a mobile tunneling and measuring device for underground coal mine roadways, comprising a measuring body 1, a dust scraping assembly 2 provided with a laser emission window of the measuring body 1, the dust scraping assembly 2 including a fixing ring 201, a slide 202 provided on the inner wall of the fixing ring 201, and symmetrically distributed sliders 203 provided inside the slide 202, the inner walls of the two sliders 203 being respectively connected to the two ends of a scraper 204, the scraper 204 being slidably connected to the fixing ring 201 via the slide 202 and the sliders 203, the scraper 204 being adapted to the laser emission window of the measuring body 1, a cleaning cotton 205 adapted to the scraper 204 being provided on the side of the scraper 204 that is in contact with the laser emission window, and a transmission mechanism adapted to the fixing ring 201 being connected to the outer walls of the two sliders 203. The inner wall of the driving wheel 206 and the outer wall of the transmission wheel 206 are provided with gear grooves 207. The tooth surface of the gear groove 207 is connected to the tooth surface of the matching driving wheel 208. The input end of the driving wheel 208 is connected to the output end of the micro motor 209. When it is necessary to clean the dust on the laser emission window, the micro motor 209 can drive the driving wheel 208 to rotate the transmission wheel 206, causing the slider 203 to drive the scraper 204 to rotate. At the same time, with the help of the cleaning cotton 205, the dust, stains and other impurities on the surface of the laser emission window can be effectively removed, thereby better maintaining the cleanliness of the window and ensuring the accuracy of laser ranging. In addition, the cleaning cotton 205 can act as a buffer between the scraper 204 and the laser emission window, reducing the scratch damage that may be caused by the scraper 204 directly contacting the window surface.

[0022] The micro motor 209, the drive wheel 208, and the transmission wheel 206 are respectively disposed inside the fixing ring 201. A number of evenly distributed support rods 3 are provided on one side of the fixing ring 201. One end of a spring 4 is connected to the opposite side of the support rods 3. A trapezoidal locking block 5 is provided on the other end of the spring 4. When the dust scraping component 2 needs to be installed, the trapezoidal locking block 5 is pressed by pressing the fixing ring 201, which causes the spring 4 to retract inward and fit into the outer wall of the laser emission window. Installation can be carried out without complicated operations. After fitting, the spring 4 drives the trapezoidal locking block 5 to reset and generate clamping force, which can effectively prevent accidental loosening during cleaning.

[0023] Working principle: First, when it is necessary to clean the dust from the laser emission window, the micro motor 209 drives the drive wheel 208 to rotate the transmission wheel 206, causing the slider 203 to rotate the scraper 204. Simultaneously, the cleaning cotton 205 effectively removes dust, stains, and other impurities from the surface of the laser emission window, thus better maintaining the cleanliness of the window and ensuring the accuracy of laser ranging. The cleaning cotton 205 also acts as a buffer between the scraper 204 and the laser emission window, reducing potential scratch damage from direct contact between the scraper 204 and the window surface. When the dust scraper assembly 2 needs to be installed, pressing the fixing ring 201 causes the trapezoidal block 5 to compress the spring 4 inwards and engage with the outer wall of the laser emission window, allowing for installation without complicated operations. After engagement, the spring 4 drives the trapezoidal block 5 to reset, generating clamping force, effectively preventing accidental loosening during cleaning. This completes the operation process of a mobile tunneling and measuring device for underground coal mine roadways.
