[0002] In the construction of mine roadways, surveying is a crucial step in ensuring that the roadways are excavated accurately according to design requirements. Accurately determining the roadway's centerline and waistline, serving as a benchmark for locating the roadway's spatial position and inclination angle, is a vital technical aspect of this process.

[0003] Laser pointers, as a measuring device, significantly improve construction efficiency and accuracy in mine tunnel construction. Their main advantages include ease of operation, high cost-effectiveness, simple installation and debugging, and the ability to emit a clearly visible laser beam, allowing workers to intuitively grasp the direction of excavation and thus ensuring construction accuracy.

[0004] However, the limited space at the top of the tunnel increased the difficulty of the installation process. Furthermore, once the laser pointer was installed, precise adjustments became complex. Therefore, simplifying the installation process and facilitating minor adjustments after installation became crucial for improving construction quality and efficiency. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0027] In mine tunnel construction surveying, after determining the centerline and waistline, a laser pointer can be used to determine the tunnel excavation direction. The advantages of using a laser pointer are that it saves time and effort, and is quick and convenient to use. Furthermore, it is inexpensive, easy to install and debug, emits visible light, and is easy to use, effectively improving the construction quality and progress of the tunnel. However, installing and debugging a laser pointer at the top of the tunnel is relatively difficult.

[0028] The specific structure of the bidirectional adjustment device for the laser pointer provided in this application will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 As shown, this application embodiment provides a two-way adjustment device for a laser pointer, including a fixing device 1, a sliding device 2, an adjustment device 3, and a laser pointer mounting base 4;

[0030] One end of the fixing device 1 is fixed to the top of the tunnel, and the other end extends to the bottom of the tunnel through the adjusting device 3, providing a stable foundation support and allowing the installation height to be adjusted. The adjusting device 3 is sleeved on the sliding device 2, supporting horizontal position adjustment. The bottom of the sliding device 2 is hinged to the laser pointer mounting base 4, which provides a rotatable mounting platform for the laser pointer, allowing angle adjustment in multiple directions.

[0031] This application provides a bidirectional adjustment device for a laser pointer. The fixing device 1 ensures stable installation of the entire device at the top of the tunnel. One end is fixed to the tunnel top, while the other end extends to the bottom of the tunnel via the adjustment device 3. This not only ensures the stability of the device but also allows the installation height to be adjusted according to actual needs. The sleeve design of the sliding device 2 and the adjustment device 3 allows the laser pointer to move horizontally as needed. This design not only improves the flexibility of the equipment but also ensures that the laser pointer maintains optimal working condition in different working environments. The adjustment device 3, as a connector, achieves not only vertical fixation but also horizontal fixation. The laser pointer mounting base 4 is hinged to the bottom of the sliding device 2, providing a rotatable mounting platform for the laser pointer. Through angle adjustments in multiple directions, the laser pointer can easily cope with various complex working environments and meet different work requirements.

[0032] Reference Figure 2 and Figure 3 As shown, in some embodiments, the top of the fixing device 1 is provided with a suspension assembly 11, which is fixedly connected to the pre-embedded parts at the top of the tunnel, ensuring the vertical stability of the entire device.

[0033] The fixed connection between the suspension assembly 11 and the embedded part provides more reliable support for the entire device. Due to the presence of the suspension assembly 11, the disassembly and reinstallation of the entire laser rangefinder bidirectional adjustment device becomes easier, reducing maintenance workload. The stable connection method reduces the risk of the device accidentally falling off, ensuring the safety of the personnel below. By introducing the suspension assembly 11 and fixing it to the embedded part, not only is the mechanical strength and stability of the laser pointer bidirectional adjustment device strengthened, but also the installation efficiency and safety are improved.

[0034] Reference Figure 2 As shown, in some embodiments, the sliding device 2 is slidably connected to the internal slide groove of the adjusting device 3 via a slide rail. The design of the slide rail and slide groove ensures that the sliding device 2 can move smoothly and linearly within the adjusting device 3. Furthermore, ball bearings are provided between the slide rail and the slide groove, and the presence of the ball bearings significantly reduces the coefficient of friction between the slide rail and the slide groove.

[0035] The design of the slide rail and slide groove reduces the friction of the sliding device 2 moving within the adjustment device 3, making the adjustment process smoother and improving the smoothness and accuracy of operation. The presence of the ball bearings reduces direct wear between components, helps maintain the long-term stable operation of the equipment, extends the service life of the slide rail, slide groove and the entire device, and if a failure occurs, the ball bearing assembly is relatively easy to replace or repair, reducing maintenance costs.

[0036] Reference Figure 4As shown, in some embodiments, the adjusting device 3 is provided with a connecting pipe 31, and the fixing device 1 is connected to the adjusting device 3 through the connecting pipe 31. The through connection provides stronger mechanical support and ensures that there is no relative displacement between the fixing device 1 and the adjusting device 3.

[0037] During installation, the fixing device 1 is positioned first, and then the adjusting device 3 is connected through the connecting pipe 31. The through connection ensures precise alignment between the two components, reduces deviations caused by installation errors, and improves the accuracy of the laser pointer. If maintenance or replacement of components is required, the through design makes disassembly and reassembly simpler and faster, reducing maintenance difficulty. The through connection achieved through the connecting pipe 31 enhances the physical connection between the fixing device 1 and the adjusting device 3, improving the reliability and durability of the overall device.

[0038] Reference Figures 2-5 As shown, in some embodiments, the sliding device 2 is L-shaped, and the L-shaped design allows for more flexible adjustments in both the vertical and horizontal directions.

[0039] The L-shaped structure offers more adjustment options within limited space, making it particularly suitable for installation in narrow or confined environments such as alleyways and tunnels. The corners of the L-shape can serve as additional reinforcement points, helping to improve the mechanical strength of the entire sliding device 2 and reduce the risk of deformation.

[0040] Reference Figure 2-5 As shown, in some embodiments, there are at least two sliding devices 2. By adjusting with multiple sliding devices, the position and angle of the laser pointer can be controlled more precisely.

[0041] Multiple sliding devices can be adjusted independently or in tandem, providing more diverse adjustment options. The adjustment method can be flexibly selected according to the actual situation, quickly finding the best working position and improving work efficiency.

[0042] Reference Figures 2-5 As shown, in some embodiments, the adjusting device 3 and the sliding device 2 are fixed together by adjusting bolts, which provide a mechanical locking function.

[0043] Once the sliding device 2 is in place, the adjusting bolt securely fixes its position, preventing movement due to external factors such as vibration. The adjusting bolt can be easily tightened or loosened using simple tools such as a screwdriver or wrench, allowing for quick setup and adjustment. By introducing the adjusting bolt to fix the adjusting device 3 to the sliding device 2, fine adjustments and a secure hold are achieved, ensuring the laser pointer accurately points to the desired position and remains stable during operation.

[0044] Reference Figures 1-5 As shown, in some embodiments, the bottom of the sliding device 2 is hinged to the laser pointer mounting base 4 via a hinge device 41, and the hinge design allows the laser pointer mounting base 4 to rotate freely within a certain range.

[0045] By connecting the bottom of the sliding device 2 to the laser pointer mounting base 4 via the hinge device 41, the different angle requirements of the laser pointer can be met. The angle of the laser pointer can be flexibly adjusted according to the requirements of specific application scenarios to ensure more accurate pointing. Even in narrow or confined spaces, the hinge design provides sufficient adjustment range, making full use of limited workspace. The hinge device 41 may include hinges, etc., and is not limited here.

[0046] Reference Figure 1-5 As shown, in some embodiments, the hinge device 41 is provided with a limiting block, which is fixed to the bottom of the sliding device 2. The presence of the limiting block can prevent the laser pointer mounting base 4 from rotating excessively.

[0047] The maximum rotation angle of the laser pointer mounting base 4 is limited by the limit block, protecting the laser pointer from mechanical damage caused by improper operation or accidents. The design of the limit block prevents changes in the device position due to misoperation or other external factors, ensuring operational safety.

[0048] Reference Figures 1-5 As shown, in some embodiments, the fixing device 1 and the adjusting device 3 are fixed together by a locking member to ensure a more secure connection between the fixing device 1 and the adjusting device 3.

[0049] The locking mechanism ensures that the adjustment device 3 will not loosen or shift unexpectedly during vertical adjustment, and the fixing method of the locking mechanism makes the adjustment process safer and more controllable.

[0050] Based on the above technical features, the working principle of the bidirectional adjustment device for the laser pointer provided in this application in practical application scenarios is as follows:

[0051] First, the fixing device 1 is installed on the top of the roadway via the suspension assembly 11, ensuring its stability and reliability. Then, the adjusting device 3 is connected to the fixing device 1 via the connecting pipe 31, and then fitted onto the sliding device 2. The vertical position of the laser pointer is adjusted using the adjusting device 3 as needed, and the adjusting device 3 is locked to the fixing device 1 using the locking mechanism. After the adjusting device 3 is fixed, the horizontal position of the laser pointer is adjusted by moving the sliding device 2 horizontally. Finally, the spatial rotation angle of the laser pointer is adjusted as needed via the hinge device 41 on the laser pointer mounting base 4 to meet the usage requirements of various roadways.

[0052] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.

[0053] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
