[0001] This utility model relates to the technical field of tunnel measurement point protection equipment, and in particular to a protective device for measurement points in underground mine tunnels. Background Technology

[0002] In tunnel excavation, it is necessary to determine the construction benchmark through surveying and setting out. To avoid damage to the survey centerline, surveyors usually fix it at the top of the tunnel. However, with the continuous improvement of mechanization in underground mines, shotcreting operations have gradually adopted mechanized methods to replace manual operations. During large-scale machinery construction, the fixed survey centerline at the top is easily damaged. This leads to surveyors having to repeatedly set out the tunnel centerline, resulting in repetitive surveying work, which not only affects construction efficiency but also increases costs. Utility Model Content

[0003] The purpose of this invention is to address the problem that the centerline of tunnel excavation measurement is usually fixed at the top, but mechanized shotcreting construction easily damages the centerline, leading to repeated measurement and setting, which affects efficiency and increases costs. This invention proposes a protective device for measurement points in underground mine tunnels.

[0005] Optionally, the locking mechanism includes a slot formed in the sleeve, a stop plate movably connected inside the slot, a spiral rod rotatably connected to the stop plate and spirally penetrating the sleeve, a handle fixedly connected to the end of the spiral rod away from the stop plate, and the sleeve fixedly connected to the first support rod.

[0006] Optionally, the clamping mechanism includes multiple rotating grooves arranged in a circular array at one end of the second support rod near the open beverage bottle. Multiple rotating rods that engage with the corresponding rotating grooves are rotatably connected inside the second support rod. A bottle mouth is fixedly connected to one end of the open beverage bottle near the second support rod. A first abutment that abuts against the inner wall of the bottle mouth is fixedly connected to one end of the rotating rod. A second abutment that is abutted by a spiral sleeve block and drives the first abutment to disengage from the rotating groove is fixedly connected to the other end of the rotating rod.

[0007] Optionally, the outer wall of the handle and the spiral sleeve block is provided with multiple anti-slip grooves arranged in a circumferential array.

[0008] Optionally, a connecting sleeve that is screwed to the end of the first support rod is fixedly connected to the middle of the base tray.

[0009] Optionally, a plurality of triangular reinforcing plates arranged in a circumferential array are fixedly connected to the base tray, and the triangular reinforcing plates are also fixedly connected to the outer wall of the connecting sleeve.

[0010] Optionally, the base tray is provided with a plurality of bolts arranged in a circumferential array.

[0026] Example

[0027] like Figures 1 to 5 As shown, this utility model proposes a protective device for measuring points in underground mine roadways, including a base tray 1. A connecting sleeve 11, which is spirally connected to the end of a first support rod 2, is fixedly connected to the center of the base tray 1. The connecting sleeve 11 spirally connects the base tray 1 and the first support rod 2, enabling a detachable connection between the two and transmitting support force. The base tray 1 has multiple bolts 13 arranged in a circumferential array. The bolts 13 pass through the base tray 1 and are screwed into the ground, fixing the entire device in a designated position and preventing displacement. The base tray 1 is sequentially equipped with a first support rod 2, a retaining sleeve 5, a second support rod 3, and an open-top beverage bottle 4. The second support rod 3 slides into the first support rod 2, with one end connected to the open-top beverage bottle 4, allowing for adjustable protective height and supporting protective components. The retaining sleeve 5 is fixed to the first support rod 2 and has an internal locking mechanism, providing a fixed fulcrum for the second support rod 3. Simultaneously, the retaining sleeve 5 prevents the end of the second support rod 3 with the retaining head 36 from arbitrarily dislodging from the first support rod 2. An open-top beverage bottle 4 is connected to a second support rod 3 via a bottle mouth 41. The open end covers the measuring point, providing physical protection. The materials used to make the open-top beverage bottle 4 are readily available and simple to manufacture; it is also safe, reliable, inexpensive, and reusable. One end of the first support rod 2 and the second support rod 3 are slidably inserted into each other, while the other end of the second support rod 3 is movably inserted into the open-top beverage bottle 4. A spiral sleeve block 35 is also spirally fitted onto the end of the second support rod 3 near the open-top beverage bottle 4. The spiral sleeve block 35 is spirally fitted onto the second support rod 3, and after rotation, it pushes the second abutment 34, controlling the opening and closing of the locking mechanism.

[0028] Secondly, such as Figure 2 and Figure 4 As shown, the sleeve 5 is equipped with a locking mechanism that fixes the second support rod 3 inside the first support rod 2. The locking mechanism includes a slot 51 formed inside the sleeve 5, which provides space for the movement of the abutment plate 52 and ensures the normal operation of the locking mechanism. The abutment plate 52 is movably connected inside the slot 51. The abutment plate 52 moves within the slot 51 and abuts the second support rod 3, fixing the second support rod 3 inside the first support rod 2 through friction. A spiral rod 53 is rotatably connected to the abutment plate 52, spiraling through the sleeve 5 and connecting to the abutment plate 52. When rotated, the spiral rod 53 moves the abutment plate 52, transmitting locking force. A handle 54 is fixedly connected to the end of the spiral rod 53 away from the abutment plate 52. The handle 54 is fixed to the end of the spiral rod 53 for easy gripping and rotation, driving the spiral rod 53 and the abutment plate 52 to move. The sleeve 5 is fixedly connected to the first support rod 2.

[0029] Among them, such as Figure 1 , Figure 3 and Figure 5As shown, the second support rod 3 has a locking mechanism at one end near the open beverage bottle 4, which is switched by a rotating spiral sleeve 35. The locking mechanism includes multiple rotating grooves 31 arranged in a circular array at the end of the second support rod 3 near the open beverage bottle 4. The rotating grooves 31 are located at the end of the second support rod 3, providing rotation space for the first abutment 33 of the rotating rod 32. Multiple rotating rods 32 are rotatably connected inside the second support rod 3, which are engaged in the corresponding rotating grooves 31. The rotating rods 32 are rotatably connected inside the second support rod 3. Through the linkage of the abutments at both ends, the opening of the beverage bottle 4 can be fixed and released.

[0030] In addition, such as Figure 1 , Figure 3 and Figure 5 As shown, a bottle mouth 41 is fixedly connected to one end of the open beverage bottle 4 near the second support rod 3. The bottle mouth 41 is inserted into one end of the second support rod 3 with a slight gap, allowing the first abutment 33 to rotate and engage the bottle mouth 41. The bottle mouth 41 is fixed to one end of the open beverage bottle 4, inserted into the second support rod 3, and held in place by the first abutment 33, thus connecting to the support rod. One end of the rotating rod 32 is fixedly connected to the first abutment 33, which abuts against the inner wall of the bottle mouth 41. The first abutment 33 rotates with the rotating rod 32, abutting against the inner wall of the bottle mouth 41, thus fixing the open beverage bottle 4 to the second support rod 3. Rubber is provided on the first abutment 33 for anti-slip purposes. The other end of the rotating rod 32 is fixedly connected to a second abutment 34, which, after being held in place by a spiral sleeve block 35, causes the first abutment 33 to disengage from the rotating groove 31. The second abutment 34, pushed by the spiral sleeve block 35, causes the rotating rod 32 to rotate, thus fixing or releasing the first abutment 33.

[0031] It is worth noting that, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the outer walls of the handle 54 and the spiral sleeve block 35 are provided with multiple anti-slip grooves arranged in a circumferential array. The anti-slip grooves are used to increase the friction between the hand and the handle 54 and the spiral sleeve block 35, so as to prevent slipping.

[0032] Furthermore, such as Figure 1 and Figure 3 As shown, multiple triangular reinforcing plates 12 arranged in a circular array are fixedly connected to the base tray 1. The triangular reinforcing plates 12 fix the base tray 1 and the connecting sleeve 11, enhancing the structural stability of the connection between the two. The triangular reinforcing plates 12 are also fixedly connected to the outer wall of the connecting sleeve 11.

[0033] Furthermore, such as Figure 4 As shown, one end of the second support rod 3 inserted into the first support rod 2 is fixedly connected to a clip 36 that is held in place by a clip 5. The clip 36 is fixed to the insertion end of the second support rod 3 and held in place by the clip 5 to prevent the second support rod 3 from coming out of the first support rod 2.

[0034] In this embodiment, when using the underground mine roadway measuring point protection device, the device is first fixed to the ground by bolts 13 on the base tray 1. The connecting sleeve 11 connects the base tray 1 and the first support rod 2, and the triangular reinforcing plate 12 enhances the stability of the connection between the two. After the second support rod 3 is slidably adjusted to a suitable length within the first support rod 2, the handle 54 on the clamping sleeve 5 is rotated, causing the spiral rod 53 to rotate. Since the spiral rod 53 and the clamping sleeve 5 are spirally connected, the abutment plate 52 moves within the slot 51 to abut against the second support rod 3, thereby fixing the second support rod 3 within the first support rod 2.

[0035] Before proceeding, the bottle mouth 41 of the open-top beverage bottle 4 needs to be inserted into the end of the second support rod 3 with the rotating groove 31. Then, rotate the spiral sleeve 35 on the second support rod 3 to push the second abutment 34 of the rotating rod 32, causing the first abutment 33 to rotate within the rotating groove 31 and abut against the bottle mouth 41, thus fixing the open-top beverage bottle 4 to the end of the second support rod 3. Then, the end of the open-top beverage bottle 4 away from the bottle mouth 41 can be aligned with the measuring point and protected. After spraying, rotate the spiral sleeve 35 in the opposite direction; the first abutment 33 will loosen and no longer hold the bottle mouth 41, thus releasing the open-top beverage bottle 4. Finally, rotate the handle 54 in the opposite direction to disengage the abutment 52 from the second support rod 3, retracting the second support rod 3 back into the first support rod 2, completing the storage process quickly and conveniently.

[0036] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
