[0033] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0035] The following is a detailed description of the underground marking and pointing device for this mine through specific embodiments:

[0036] Reference Figures 1 to 7 As shown in the figure, some embodiments of this utility model provide a marking and marking device for underground mines, including a device body 1, a spraying assembly 2, a jacking mechanism 3, and a micro switch 4.

[0037] The spraying assembly 2 is mounted on the main body 1 of the device and includes a storage tank 21, a pump body 22, and a spray head 23 connected in sequence. The pump body 22 can pump the paint in the storage tank 21 into the spray head 23. The push mechanism 3 is mounted on the main body 1 and slides in cooperation with the main body 1. There are two push mechanisms 3, which are symmetrically arranged on both sides of the spray head 23. There are two micro switches 4, which are symmetrically arranged on both sides of the spray head 23. The micro switches 4 are electrically connected to the pump body 22 and are triggered by the push mechanism 3 on the corresponding side. After both micro switches 4 are triggered, the pump body 22 draws the paint in the storage tank 21 into the spray head 23 and marks the point through the spray head 23.

[0038] In other words, there are two push mechanisms 3 and two micro switches 4, symmetrically distributed on both sides of the nozzle 23. When both push mechanisms 3 are in contact with the inner wall of the tunnel, the push mechanism 3 slides relative to the main body 1 under the reaction force of the inner wall of the tunnel. Only after the push mechanisms 3 on both sides have slid the same distance can the corresponding micro switch 4 be triggered. Both micro switches 4 are electrically connected to the liquid pump. After both micro switches 4 are triggered, the pump body 22 can be energized and operated to pump the paint in the storage tank 21 into the nozzle 23 for spraying, thereby realizing the marking point inside the tunnel. At the same time, the fact that the push mechanisms 3 on both sides slide the same distance before starting to spray the point can also ensure that the nozzle 23 is perpendicular to the inner wall of the tunnel, which can ensure the uniformity of the spraying and make the marking complete. The overall structure is simple and the design is reasonable, which greatly improves the efficiency of the marking point and makes it easy to promote and use.

[0039] In practice, the underground marking and pointing device of this application can be powered by an external power source, which can be carried by the operator, greatly improving the overall portability and operability.

[0040] In some embodiments, a fixed shell 11 is provided on the main body 1 of the device. The fixed shell 11 is hollow inside, and mounting holes 111 are provided on both side walls of the fixed shell 11 along the sliding direction of the pushing mechanism 3. The pushing mechanism 3 includes a pushing column 31, which passes through two mounting holes 111 in sequence and slides with the mounting holes 111 so that the pushing column 31 can slide relative to the fixed shell 11, that is, the pushing column 31 can slide relative to the main body 1 of the device. Specifically, the fixed shell 11 can be connected to the main body 1 of the device by fasteners such as screws to facilitate the installation and disassembly of the pushing mechanism 3, and to facilitate maintenance and replacement.

[0041] In practice, the jacking column 31 is used to abut against the inner wall of the tunnel. Under the reaction force of the inner wall of the tunnel, it can push the jacking column 31 to slide relative to the main body 1 of the device. Figure 4As shown, the micro switch 4 is disposed on the side of the fixed shell 11 away from the inner wall of the tunnel along the sliding direction of the push column 31. When the push column 31 slides away from the inner wall of the tunnel, it can gradually approach the micro switch 4 to trigger the micro switch 4.

[0042] Furthermore, the jacking mechanism 3 also includes an elastic element 32, which is disposed inside the fixed housing 11. A retaining ring 311 is provided on the portion of the jacking column 31 located inside the fixed housing 11. One end of the elastic element 32 is connected to the retaining ring 311, and the other end is connected to the inner wall of the fixed housing 11. When the jacking column 31 abuts against the inner wall of the tunnel, the jacking column 31 can move towards the micro switch 4. The retaining ring 311 on the jacking column 31 can cause the elastic element 32 to undergo elastic deformation. When the jacking column 31 detaches from the inner wall of the tunnel, under the elastic force of the elastic element 32, the retaining ring 311 can be driven back to its original position, thereby releasing the micro switch 4 and stopping the spray nozzle 23 from spraying. Specifically, the elastic element 32 is a spring structure, which is sleeved on the outside of the jacking column 31.

[0043] Reference Figure 7 As shown, the elastic element 32 is disposed on the side of the retaining ring 311 close to the micro switch 4. The elastic element 32 does not need to be connected to the retaining ring 311. It can also be compressed under the action of the retaining ring 311 and the fixed shell 11. Of course, the elastic element 32 can also recover its deformation to drive the retaining ring 311 away from the micro switch 4.

[0044] In some embodiments, refer to Figure 7 As shown, a protective rubber head 33 is provided at one end of the push post 31 near the micro switch 4. In specific implementation, the protective rubber head 33 is cylindrical in shape. On the one hand, it can increase the contact area with the micro switch 4 to prevent stress concentration and damage to the micro switch 4. On the other hand, the rubber itself has a certain degree of compressibility, which can effectively protect the micro switch 4.

[0045] Continue to refer to Figure 7 As shown, a wear-resistant head 34 is provided at the end of the jacking column 31 near the inner wall of the tunnel to increase its structural strength and extend its service life. Specifically, the wear-resistant head 34 is universally connected to the end of the jacking column 31 to improve the contact performance between the wear-resistant head 34 and the inner wall of the tunnel. Specifically, the end of the jacking column 31 furthest from the microswitch 4 is formed into a spherical end, which is universally connected to the wear-resistant head 34 to ensure sufficient contact area between the wear-resistant head 34 and the inner wall of the tunnel, thus guaranteeing contact performance.

[0046] In some embodiments, the underground marking and marking device further includes a drive mechanism 5, which is mounted on the device body 1 and connected to the nozzle 23 to drive the nozzle 23 to move relative to the device body 1. It is understood that when the nozzle 23 moves relative to the device body 1, the distance between the nozzle 23 and the inner wall of the tunnel can be changed to adjust the marking and marking coverage area as needed.

[0047] In specific implementation, refer to Figure 2 and Figure 3 As shown, the drive mechanism 5 includes a drive motor 51, a lead screw 52, ​​a guide rail 53, and a slider 54. The drive motor 51 is connected to the lead screw 52, ​​and the slider 54 is slidably engaged with the guide rail 53. The slider 54 is sleeved on the lead screw 52 and threadedly engaged with it. The nozzle 23 is connected to the slider 54. In other words, the slider 54 is confined within the guide rail 53. The drive motor 51 can drive the lead screw 52 to rotate. When the lead screw 52 rotates, it can drive the slider 54 to move along the axis of the lead screw 52, ​​thereby causing the nozzle 23 connected to the slider 54 to move accordingly, thus adjusting the distance between the nozzle 23 and the inner wall of the tunnel.

[0048] Reference Figure 2 As shown, a cantilever 55 is provided on the slider 54, and the nozzle 23 is provided on the cantilever 55 and connected to the slider 54 through the cantilever 55. The cantilever 55 is set beyond the guide rail 53 along the sliding direction of the slider 54, so that the nozzle 23 can be relatively far away from the guide rail 53. In this way, during the subsequent spraying, the possibility of paint entering the interior of the guide rail 53 is reduced, thus avoiding affecting the movement of the slider 54.

[0049] Of course, it should be noted that the drive mechanism 5 can also be other structures, such as electric push rods, etc. This application does not limit this, as long as it can drive the nozzle 23 to move relative to the main body 1 of the device, thereby adjusting the distance between the nozzle 23 and the inner wall of the tunnel to adjust the spraying range of the marked point.

[0050] In some embodiments, refer to Figure 1 and Figure 3 As shown, a support frame 12 is provided on the main body 1 of the device, and the drive mechanism 5 is mounted on the support frame 12. The support frame 12 and the main body 1 of the device together enclose a clearance space. (Refer to...) Figure 6 As shown, the pump body 22 and the nozzle 23 are connected by a connecting pipe 24, which passes through a clearance space. It is understood that the drive mechanism 5 is mounted on the support frame 12, which provides installation space for the drive mechanism 5, avoiding excessive occupation of installation space on the main body 1. Simultaneously, the connecting pipe 24 passing through the clearance space, along with the support frame 12, prevents the connecting pipe 24 from swaying freely on the main body 1, thus ensuring the connection performance between the connecting pipe 24 and the nozzle 23 and pump body 22.

[0051] In a specific implementation, the support frame 12 includes support legs and a support part. There are multiple support legs, and the multiple support legs together support the support part. The drive mechanism 5 is set on the support part. The support legs and the support part together form a clearance space. The support legs can limit the shaking of the connecting pipe 24.

[0052] Reference Figure 3 As shown, the main body 1 of the device includes a support plate 13, a spraying component 2, a pushing mechanism 3 and a micro switch 4 are all mounted on the support plate 13. The support plate 13 has a hollow hole 131 to reduce the weight of the support plate 13 and facilitate hand-held application.

[0053] Reference Figure 5 As shown, the underground marking and pointing device in the mine also includes an operating handle 6, which is detachably threadedly connected to the main body 1 of the device. The operating handle 6 supports the main body 1 of the device and allows for hand-held marking and pointing operations. Specifically, the operating handle 6 can adopt a multi-section assembly structure, which facilitates on-site assembly and installation. After the operation is completed, it can be disassembled to reduce the overall size, making it easier to carry and transport.

[0054] In practice, the main body 1 of the device is provided with multiple connecting parts 14. The connecting parts 14 are cylindrical structures and the inner wall of the connecting parts 14 is formed with a threaded structure. The operating handle 6 and the storage tank 21 can be detachably threadedly connected to the connecting parts 14, which is convenient for assembly and carrying.

[0055] When using the underground marking and marking device of this application, the entire assembly is completed. At the same time, the operator holds the operating handle 6 and lifts the main body 1 of the device to a certain height through the operating handle 6. Then, the two wear-resistant heads 34 are controlled to contact the inner wall of the roadway, and the main body 1 of the device is moved closer to the inner wall of the roadway. By setting two jacking mechanisms 3 and two micro switches 4, the two micro switches 4 are electrically connected to the pump body 22. When both wear-resistant heads 34 are in contact with the inner wall of the roadway, the two jacking columns 31 compress the elastic element 32 at the same time, so that the two protective rubber heads 33 contact the micro switches 4 at the same time. This causes the two micro switches 4 to act at the same time, and the pump body 22 can be powered on to pump the paint in the storage tank 21 to the nozzle 23 for spraying, so as to facilitate marking on the inner wall of the roadway.
