[0002] In the construction process, the accuracy of prefabricated shield segments is crucial. To meet this requirement, laser positioning systems have gradually become the mainstream choice due to their high precision and repeatability. The initial laser positioning system mainly relies on manual operation to ensure the correct position and angle of the shield segment. Modern laser positioning systems combine with mechanical arms to achieve higher levels of precision control, promoting the automation level of the prefabricated shield segment process.

[0040] Currently, laser positioning systems usually employ a combination of laser range finders, three-dimensional scanners, and laser projection systems for measurement and calibration. This combination can provide high measurement accuracy, which is used to ensure the accurate prefabrication of engineering components, such as shield segments.

[0041] However, in laser positioning systems, it is difficult to maintain the stability of the grating mirror, which is prone to position deviation due to vibration or external force. In addition, the current mechanical arm has a limited adjustment range, making it difficult to achieve precise fine-tuning of the grating mirror, resulting in positioning errors. The complexity of the operation process increases the time and labor cost of prefabricating shield segments, which is somewhat inconsistent with the expected automation and efficiency.

[0042] To solve this technical problem, the present application proposes a laser emitter and detection system.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 In an embodiment of the present application, the laser emitter comprises a limiting ring 500, a mounting ring 100, a limiting sheet 200, a clamping mechanism 300, a grating mirror 700, and a plurality of pull hook mechanisms 800. The mounting ring 100 is coaxially arranged with the limiting ring 500, and a containing space 501 is formed between the outer wall of the mounting ring 100 and the inner wall of the limiting ring 500. The limiting sheet 200 is arranged on the mounting ring 100. The clamping mechanism 300 is slidably arranged on the mounting ring 100 along the radial direction of the mounting ring 100, and is arranged opposite to the limiting sheet 200. The clamping mechanism 300 and the limiting sheet 200 jointly form a clamping space 301. The grating mirror 700 is arranged in the clamping space 301, and the clamping mechanism 300 can move along the radial direction of the mounting ring 100 between a release position away from the grating mirror 700 and a clamping position close to the grating mirror 700, so as to correspondingly release or clamp the grating mirror 700. The plurality of pull hook mechanisms 800 are arranged at intervals along the circumferential direction of the limiting ring 500. Each pull hook mechanism 800 extends along the axial direction of the limiting ring 500, and the two ends of each pull hook mechanism 800 along its extension direction are respectively a connecting portion and a pull hook portion. The connecting portion of each pull hook mechanism 800 is slidably connected to the limiting ring 500 along the axial direction of the limiting ring 500, and the pull hook portion of each pull hook mechanism 800 extends into the containing space 501 and is detachably connected to the mounting ring 100. Each pull hook mechanism 800 is used to drive part of the mounting ring 100 to tilt towards the limiting ring 500, so as to drive part of the grating mirror 700 to tilt towards the limiting ring 500.

[0044] Specifically, the plurality of hook mechanisms 800 are arranged along the circumferential direction of the limiting ring 500, and the connecting portions of the hook mechanisms 800 can slide along the axial direction of the limiting ring 500, so that the hook mechanisms 800 can remain flexible during the position and angle adjustment of the grating lens 700. The hook portions extend into the accommodation space 501 and are detachably connected with the mounting ring 100, so as to ensure effective force transmission during the fine adjustment and prevent interference between the hook portions, i.e., to avoid friction between the hook portions and the mounting ring 100 when driving the mounting ring 100 to tilt, thereby reducing the loss. That is, the hook portions are hinged with the mounting ring 100.

[0045] In the implementation process, the hook mechanisms 800 can drive part of the mounting ring 100 to tilt towards the limiting ring 500, thereby driving the corresponding part of the grating lens 700 to tilt towards the limiting ring 500. This improves the fine adjustment accuracy of the grating lens 700, so that the laser emitter can more accurately align with the target prefabricated shield segment during the execution of the laser positioning task, thereby improving the overall performance of the laser positioning system. The number and spacing of the hook mechanisms 800 can be adjusted to flexibly adjust the reaction speed and accuracy of the laser emitter, and the adjustment can be made according to the requirements of different application occasions to meet the actual prefabrication requirements of various shield segments. In addition, the slidable connection of the hook mechanisms 800 to the limiting ring 500 also effectively reduces the errors caused by improper installation, thereby ensuring the stability and accuracy of the grating lens 700.

[0046] In addition, through the coaxial arrangement of the mounting ring 100 and the limiting ring 500, the accommodation space 501 formed thereby can provide space for the tilting process of the mounting ring 100 and the grating lens 700.

[0047] It should be noted that the driving source for adjusting the clamping mechanism 300 between the release position away from the grating lens 700 and the clamping position close to the grating lens 700 is manual adjustment or a driving motor in the prior art.

[0048] In the implementation process, when the grating lens 700 is installed in the clamping space 301, the edge of the grating lens 700 is located on the limiting piece 200 and is abutted by the mounting ring 100, so as to limit the displacement of the grating lens 700 in the axial direction of the mounting ring 100; the clamping mechanism 300 and the limiting portion 210 jointly limit the displacement of the grating lens 700 in the radial direction of the mounting ring 100. Therefore, the position of the grating lens 700 arranged in the clamping space 301 is fixed by the limiting piece 200, the mounting ring 100, and the clamping mechanism 300.

[0049] More specifically, the clamping mechanism 300 can move along the radial direction of the mounting ring 100, and can be adjusted between a release position away from the grating lens 700 and a clamping position close to the grating lens 700, so as to quickly install and dismount the grating lens 700, and ensure that the grating lens 700 is stably clamped during work and easily released during maintenance or replacement.

[0050] It should be understood that the mounting ring 100 provides a stable base for the grating lens 700, and the limiting piece 200 thereon can provide a stable mounting point, thereby enhancing the stability and accuracy of the grating lens 700. The limiting piece 200 enables the grating lens 700 to be reliably positioned in the clamping space 301, thereby avoiding light deviation caused by vibration or other external forces during work of the laser positioning system, and improving the overall correction effect. In addition, the clamping mechanism 300 is slidably arranged along the radial direction of the mounting ring 100, which not only enables the clamping mechanism 300 to be flexibly moved to the clamping position and the release position, but also facilitates quick adjustment by the operator. In actual operation, the clamping mechanism 300 can effectively control the clamping force of the grating lens 700, so as to ensure that the grating lens 700 will not be damaged due to excessive pressure during clamping. At the same time, the clamping mechanism 300 is arranged opposite to the limiting piece 200, and together forms the clamping space 301, thereby further ensuring the stability of the grating lens 700. In addition, the grating lens 700 is arranged in the clamping space 301, and can be released or clamped under the regulation of the clamping mechanism 300, thereby greatly simplifying the installation and replacement process of the grating lens 700, and eliminating the inconvenience and risks caused by the traditional threaded connection method. The operator can complete the release and installation of the grating lens 700 in a relatively short time, thereby reducing the loss caused by frequent adjustment, and effectively improving the work efficiency. Through the cooperative arrangement of the mounting ring 100, the limiting piece 200 and the clamping mechanism 300, the use convenience and reliability of the grating lens 700 are significantly improved, not only the stability of the grating lens 700 is improved, but also the accuracy during calibration is enhanced, thereby effectively preventing the laser positioning system from causing light deviation due to vibration or external force during work, and improving the correction effect of the laser light of the laser positioning system. At the same time, the clamping mechanism 300 is slidably arranged along the radial direction of the mounting ring 100, so that the grating lens 700 can be released or clamped simply under the regulation of the clamping mechanism 300, thereby simplifying the installation and replacement process of the grating lens 700, and eliminating the complexity and potential risks caused by the traditional threaded connection method. Moreover, the operator can complete the installation and release of the grating lens 700 in a relatively short time, thereby reducing the element wear caused by frequent adjustment, effectively improving the work efficiency, making the use experience of the laser positioning system more smooth, and better meeting the demand for high-precision and high-efficiency of the prefabricated shield segment in modern construction.

[0051] For ease of understanding, a specific embodiment is shown here:

[0052] First, place the grating lens 700 in the mounting ring 100 and ensure that it is properly aligned with the limiting ring 500, and fix the grating lens 700 with the locking mechanism (such as the clamping mechanism 300) of the mounting ring 100 to prevent displacement during subsequent adjustment. Ensure that the connecting parts of all the hook mechanisms 800 are aligned with the edges of the limiting ring 500 and are in a state of not exerting force. Check whether the hook parts of the hook mechanisms 800 can smoothly reach the mounting ring 100, avoiding uneven adjustment due to excessive tightness or looseness. Then, by controlling the operating device (such as an electric motor or a manually rotating handle) of the hook mechanisms 800, exert force on each hook part one by one or simultaneously. The exerted force makes the hook part tilt inward, thereby driving the part of the mounting ring 100 corresponding to this hook mechanism 800 to tilt towards the limiting ring 500. At this time, the corresponding part of the grating lens 700 also adjusts the angle. Then, use a laser range finder or other precise measuring tool to monitor the emission angle of the laser beam, and real-time feedback the adjustment of the grating lens 700. According to the feedback information, slightly adjust the exerted force of the hook mechanisms 800 to make the grating lens 700 reach the required optimal angle. For some application occasions, fixed devices (such as additional locking screws or clamps) can also be set to further stabilize the grating lens 700.

[0053] When exerting force, attention should be paid to the uniform distribution of force to avoid uneven tilting angle of the grating lens 700 due to excessive force of a hook mechanism 800. During the adjustment process, regularly check the sliding state of each hook mechanism 800 to ensure that it remains flexible throughout the process and prevent jamming. Through the cooperation of the limiting ring 500, the mounting ring 100 and the multiple hook mechanisms 800, the problem that the existing laser positioning system is difficult to provide a control basis for the position and angle fine-tuning of the grating lens 700 and difficult to realize fine-tuning of the grating lens 700 in the process of prefabricating shield segments is effectively solved. The mounting ring 100 simplifies the maintenance and replacement process of the grating lens 700, making the installation and disassembly of the grating lens 700 more convenient. The multiple hook mechanisms 800 are arranged along the circumferential direction of the limiting ring 500, and the connecting parts can slide along the axial direction of the limiting ring 500, ensuring that each hook mechanism 800 can flexibly adjust the position and angle of the grating lens 700 during fine-tuning, ensuring the efficiency and accuracy of the grating lens 700 during fine-tuning. In addition, the hook mechanisms 800 can drive the part of the mounting ring 100 to tilt towards the limiting ring 500, thereby driving the corresponding part of the grating lens 700 to tilt, significantly improving the fine-tuning accuracy of the grating lens 700, enabling the laser emitter to more accurately aim at the target prefabricated shield segment when performing laser positioning tasks, thereby improving the overall performance of the laser positioning system and the forming quality of the prefabricated shield segment.

[0054] The technical scheme provided by the present application effectively solves the problems of poor stability and inaccurate adjustment of the grating mirror 700 in the prior art through the synergistic effect of the limiting ring 500, the mounting ring 100, the limiting sheet 200, the clamping mechanism 300 and the plurality of pull hook mechanisms 800. The limiting ring 500 and the mounting ring 100 are coaxially arranged to form a stable frame, reducing the influence of external vibrations on the grating mirror 700 during the process of shield segment prefabrication. The limiting sheet 200 provides a fixed point to limit the displacement of the grating mirror 700 in the axial and radial directions, improving its stability. At the same time, the clamping mechanism 300 slides along the radial direction of the mounting ring 100, allowing the grating mirror 700 to be quickly released or clamped, simplifying the installation and maintenance process of the grating mirror 700. The plurality of pull hook mechanisms 800 are arranged circumferentially along the limiting ring 500, each mechanism can slide independently and apply force uniformly, thereby accurately adjusting the angle of the grating mirror 700 and avoiding errors caused by uneven force. Not only improves the fixing and adjustment accuracy of the grating mirror 700, but also simplifies the production operation process of the prefabricated shield segment, reduces the time and labor cost. And speed up the production speed of the prefabricated shield segment, reduce human error, make the laser positioning system show higher performance and reliability in the prefabrication of shield segment, meet the requirements of modern engineering on precision and efficiency.

[0055] As an optional implementation manner of the present embodiment, the laser emitter further comprises a plurality of damping mechanisms 600, which are arranged alternately with the plurality of pull hook mechanisms 800; the plurality of damping mechanisms 600 are arranged circumferentially along the limiting ring 500, each damping mechanism 600 extends along the axial direction of the limiting ring 500; the two ends of each damping mechanism 600 along its extension direction are respectively a free end and a connecting end, the connecting end of each damping mechanism 600 is connected with the limiting ring 500, and the free end of each damping mechanism 600 extends into the accommodating space 501 and is connected with the mounting ring 100.

[0056] Specifically, the plurality of damping mechanisms 600 are arranged circumferentially along the limiting ring 500, so that the damping mechanisms 600 are uniformly distributed in the circumference of the limiting ring 500, thereby reducing the influence of vibration on the grating mirror 700 when the mechanical arm moves. The connecting end of the damping mechanism 600 is connected with the limiting ring 500, which ensures the stability and reliability of the damping mechanism 600, so that the free end can effectively absorb and dissipate the vibration from the mechanical arm. Such arrangement not only enhances the stability of the grating mirror 700, but also significantly prolongs the service life of the grating mirror 700, reduces wear and maintenance frequency.

[0057] More specifically, the free end of each damping mechanism 600 extends into the accommodation space 501 and connects with the mounting ring 100. The damping mechanism 600 can effectively isolate external vibration transmission during operation, avoiding direct vibration on the grating mirror 700. In addition, the damping mechanism 600 can be adjusted according to the specific use environment to adapt to different vibration frequencies and amplitudes, providing a guarantee for the accurate positioning of the grating mirror 700. Multiple damping mechanisms 600 not only improve the stability and durability of the grating mirror 700, but also significantly reduce the maintenance and replacement frequency of the grating mirror 700. The damping mechanism 600 can effectively absorb and dissipate vibrations from the mechanical arm, reducing the direct impact of vibration on the grating mirror 700, allowing the grating mirror 700 to maintain good working condition in long-term practical application, prolonging its service life.

[0058] Please continue to refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 , and refer to Figure 9 , as an optional embodiment of the damping mechanism 600, the damping mechanism 600 includes a connecting seat 610, a compression spring 620 and a jaw assembly 630, the connecting seat 610, the compression spring 620 and the jaw assembly 630 are arranged along the circumference of the limiting ring 500, the connecting seat 610 is connected with the inner wall of the limiting ring 500 and forms a connecting end, one end of the compression spring 620 is connected with the connecting seat 610, the other end of the compression spring 620 is connected with the jaw assembly 630, and the jaw assembly 630 is detachably clamped on the outer wall of the mounting ring 100 and forms a free end.

[0059] Specifically, the connecting seat 610 is connected with the inner wall of the limiting ring 500, forming the connecting end of the damping mechanism 600, ensuring the reliability and stability of the damping mechanism 600 during operation. One end of the compression spring 620 is connected with the connecting seat 610, and the other end is connected with the jaw assembly 630. The compression spring 620 provides moderate elasticity, allowing the jaw assembly 630 to maintain flexibility and recovery ability when subjected to external vibration, thereby effectively absorbing and buffering vibration.

[0060] More specifically, the jaw assembly 630 is detachably clamped on the outer wall of the mounting ring 100, improving the convenience of maintenance. When maintaining or replacing the grating mirror 700, the worker can quickly release the jaw, which is convenient to operate without the need to disassemble the entire structure. At the same time, the jaw assembly 630 can stably clamp the grating mirror 700, ensuring that it is not disturbed in the working state, further reducing the risk of wear and tear.

[0061] As another optional embodiment of the damping mechanism 600, the compression spring 620 in the damping mechanism 600 not only provides a structural basis for the reset of the mounting ring 100 after tilting, but also ensures that the mounting ring 100 is always in a state of tension towards one side of the limiting ring 500. This design enhances the stability of the mounting ring 100 when tilted, thereby improving the tilt control accuracy of the grating lens 700.

[0062] Specifically, when a certain hook mechanism 800 hooks one side of the mounting ring 100, the mounting ring 100 will be affected and tilted. At the same time, the remaining unaffected hook mechanisms 800 remain stationary. During the tilting of the mounting ring 100, the compression spring 620 of the damping mechanism 600 will exert a tensioning force to ensure the stability of the mounting ring 100.

[0063] When the hook mechanism 800 resets, the compression spring 620 will return to its initial state, thereby causing the mounting ring 100 to reset along with the hook mechanism 800. The main function of the hook mechanism 800 is to achieve the tilting of the mounting ring 100 without the need for complex connections or adjustments, effectively reducing the contact area and assembly points between the hook mechanism 800 and the mounting ring 100, and improving the durability of the hook mechanism 800 and the mounting ring 100. This ensures the stability and long-term reliability of the laser positioning system during use, while simplifying the assembly and maintenance process.

[0064] As an optional embodiment of the clamping jaw assembly 630, the clamping jaw assembly 630 includes an arc-shaped plate 631 and a limiting strip 632, the limiting strip 632 is in an L-shaped structure, one end of the limiting strip 632 is connected with the arc-shaped plate 631, and the other end of the limiting strip 632 is spaced apart from the arc-shaped plate 631 to form an assembly space 601, part of the mounting ring 100 is arranged in the assembly space 601, and the arc-shaped plate 631 has an arc that is matched with the mounting ring 100.

[0065] Specifically, the limiting strip 632 is in an L-shaped structure, one end of which is connected with the arc-shaped plate 631, and the other end is spaced apart from the arc-shaped plate 631 to form an assembly space 601, so that the clamping jaw assembly 630 can flexibly adapt to the shape of the mounting ring 100 during clamping.

[0066] The assembly space 601 enables the part of the mounting ring 100 to be smoothly placed therein, thereby ensuring good cooperation between the clamping jaw assembly 630 and the mounting ring 100. The curvature of the arc-shaped plate 631 is adapted to the mounting ring 100, and this matching design not only enhances the stability of clamping, but also ensures that the clamping jaw assembly 630 can uniformly apply pressure when clamping, reducing potential damage to the grating lens 700. Through the combination of the arc-shaped plate 631 and the limiting strip 632, the clamping jaw assembly 630 can provide a smooth and reliable operation experience during clamping and releasing. Especially when maintaining or replacing the grating lens 700, the user can conveniently adjust the clamping jaw assembly 630 to achieve quick release or clamping without affecting the overall stability of the laser positioning system.

[0067] In addition, the limiting strip 632 and the arc-shaped plate 631 are provided with shock isolation pads on the side facing the mounting ring 100.

[0068] Specifically, the shock isolation pads can effectively isolate vibrations from the mechanical arm or other external sources, acting as a buffer. In combination with the limiting strip 632 and the arc-shaped plate 631, the shock isolation pads form a multi-level vibration reduction system, which can further absorb and dissipate vibration energy, reducing the possibility of their transmission to the mounting ring 100 and the grating lens 700.

[0069] In addition, when clamping the grating lens 700, the shock isolation pads can provide more uniform pressure while avoiding slight displacement caused by vibrations, thereby further protecting the precision and stability of the grating lens 700.

[0070] Please continue to refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 In an embodiment of the present application, the clamping mechanism 300 includes a guide column 310 and a clamping piece 330, and the clamping piece 330 and the limiting piece 200 jointly form a clamping space 301; the guide column 310 extends along the radial direction of the mounting ring 100, the guide column 310 is installed on the outer wall of the mounting ring 100, and the clamping piece 330 is slidably installed on the guide column 310 and can move between a release position and a clamping position, corresponding to release or clamp the grating lens 700.

[0071] Specifically, the clamping piece 330 forms a clamping space 301 with the limiting part 210 of the limiting piece 200 for accommodating the grating mirror 700. The clamping piece 330 can move between a release position and a clamping position to achieve the release or clamping of the grating mirror 700. The guide column 310 extends along the radial direction of the mounting ring 100 and is mounted on the outer wall of the mounting ring 100. The clamping piece 330 is slidably mounted on the guide column 310 to guide the movement of the clamping piece 330 in the radial direction of the mounting ring 100, thereby improving the clamping stability of the grating mirror 700. The elastic return member 320 is sleeved on the guide column 310 and located between the clamping piece 330 and the mounting ring 100. The elastic return member 320 provides an elastic force to automatically return the clamping piece 330 to a preset position after release, ensuring that the clamping piece 330 can stably clamp the grating mirror 700.

[0072] In an embodiment of the present application, the clamping mechanism 300 further comprises a radial displacement driving member mounted on the mounting ring 100. The radial displacement driving member is connected with the clamping piece 330 and used to drive the clamping piece 330 to move between the release position and the clamping position, corresponding to the release or clamping of the grating mirror 700.

[0073] Specifically, the provision of the radial displacement driving member provides power support for the clamping mechanism 300, so that the operator can quickly adjust the position of the clamping piece 330 through simple operation, easily complete the clamping or release of the grating mirror 700, and greatly reduce the complexity and time cost of human operation. Moreover, the radial displacement driving member also ensures the stability of the clamping piece 330 during movement, avoiding unnecessary shaking during clamping or release that may cause damage to the grating mirror 700. In addition, the use of the radial displacement driving member also effectively improves the accuracy of operation, so that the grating mirror 700 can be accurately positioned in the clamping space 301, further enhancing the overall performance of the laser positioning system.

[0074] In an embodiment of the present application, the clamping mechanism 300 further comprises an elastic return member 320. The elastic return member 320 is sleeved on the guide column 310, and one end of the elastic return member 320 is connected with the clamping piece 330, and the other end of the elastic return member 320 is connected with the mounting ring 100.

[0075] Specifically, the setting of the elastic reset member 320 greatly enhances the automation function of the clamping mechanism 300. After the operator moves the clamping piece 330 to the release position, the elastic reset member 320 will restore the clamping piece 330 to the clamping position through its elastic properties. This automatic reset function not only reduces manual intervention of the operator, improves work efficiency, but also ensures that the grating mirror 700 will not fall off due to accidental collision in the non-clamping state. In addition, the elastic reset member 320 can absorb external impact or vibration, further enhancing the stability of the clamping piece 330, effectively avoiding the position deviation of the grating mirror 700 caused by vibration, and ensuring the accuracy and stability of the laser light.

[0076] More specifically, the elastic reset member 320 is a spring, one end of the elastic reset member 320 is connected to the side of the clamping piece 330 facing the mounting ring 100, and the other end of the elastic reset member 320 is connected to the outer wall of the mounting ring 100. The embodiment provides a stable sliding path for the clamping piece 330 through the guide column 310, and combines the deformation reset function of the elastic reset member 320 to ensure that the clamping piece 330 can quickly and reliably move to the required position, enhancing the convenience and stability of the disassembly and assembly operation of the grating mirror 700.

[0077] In an embodiment of the clamping mechanism 300, the clamping piece 330 and the limiting part 210 of the limiting piece 200 are provided with a buffer 400 on the side facing the grating mirror 700.

[0078] It should be noted that the buffer 400 is a rubber part in the prior art.

[0079] Specifically, the buffer 400 can effectively absorb the impact force between the clamping piece 330 and the grating mirror 700, reducing damage caused by collision during clamping or releasing, thereby protecting the grating mirror 700 and its optical performance. In addition, during the operation of the laser emitter, vibration or external impact may occur, and the buffer 400 can provide additional shock absorption effect to ensure that the grating mirror 700 always maintains a stable working state. In addition, by using the buffer 400 to provide a soft contact surface during clamping, it helps to prevent the grating mirror 700 from shifting or being inaccurate in position during clamping, thereby improving the overall calibration accuracy of the laser positioning system. Moreover, the use of the buffer 400 can reduce the wear and tear caused by frequent operation on the clamping mechanism 300 and the grating mirror 700, thereby prolonging the service life.

[0080] In an embodiment of the limiting piece 200, the number of limiting pieces 200 is multiple, and the multiple limiting pieces 200 are arranged at intervals along the circumference of the mounting ring 100, and the clamping mechanism 300 is arranged opposite to any limiting piece 200.

[0081] Specifically, the plurality of limiting pieces 200 are distributed along the circumference of the mounting ring 100, which can provide more uniform support for the clamped grating mirror 700, ensuring that the grating mirror 700 can be stably fixed during clamping, reducing local stress concentration. Moreover, the arrangement of the plurality of limiting pieces 200 makes the adjustment of the clamping space 301 more flexible, which can adapt to grating mirrors 700 of different types or sizes, enhancing the compatibility of the laser emitter.

[0082] It should be noted that the relative arrangement in the embodiment refers to the relative position relationship, including but not limited to the symmetrical relationship, and the relative arrangement can also be the gap between the clamping piece 330 and the adjacent two limiting pieces 200.

[0083] Please continue to refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , and refer to Figure 8 In the embodiment of the present application, each hook mechanism 800 includes a hook assembly 810, a hinge seat 820, a guide bar 830, and an axial displacement driving member 840. The hook assembly 810 forms a hook portion, and the guide bar 830 forms a connecting portion. One end of the hook assembly 810 is hinged to the guide bar 830 through the hinge seat 820, and the other end of the hook assembly 810 is detachably connected to the mounting ring 100. The axial displacement driving member 840 is installed on the limiting ring 500, and the axial displacement driving member 840 is connected to the guide bar 830 and is used to drive the guide bar 830 to slide along the axis of the limiting ring 500, so as to drive part of the mounting ring 100 to tilt towards the limiting ring 500, and part of the grating mirror 700 to tilt towards the limiting ring 500.

[0084] Specifically, at the beginning of the implementation process, the axial displacement driving member 840 receives a control signal, and after the axial displacement driving member 840 is activated, it drives the guide bar 830 to slide along the axis of the limiting ring 500. One end of the hook assembly 810 is hinged to the guide bar 830, and the other end is detachably connected to the mounting ring 100. With the movement of the guide bar 830, the hook assembly 810 is tilted through the hinge seat 820, so that the hook assembly 810 can rotate flexibly during adjustment, thereby effectively adjusting the angle of the mounting ring 100. When the guide bar 830 slides along the limiting ring 500, the hook portion is connected to the mounting ring 100, causing part of the mounting ring 100 to tilt towards the limiting ring 500, and in turn causing the corresponding part of the grating mirror 700 to tilt towards the limiting ring 500.

[0085] More specifically, the axial displacement driving member 840 can be used to drive the guide bar 830 to make reciprocating linear motion along the circumference of the mounting ring 100 and the limiting ring 500, so as to make the mounting ring 100 drive the grating mirror 700 to tilt or reset.

[0086] The embodiment significantly improves the fine adjustment accuracy of the grating lens 700, so that the laser emitter can more accurately align the target prefabricated shield segment when performing the laser positioning task. In addition, the draw hook mechanism 800 not only enhances the stability during fine adjustment, but also ensures the flexibility and accuracy of the adjustment process of the grating lens 700, thereby effectively improving the overall performance of the laser positioning system.

[0088] Specifically, the draw hook space 801 not only ensures the stability of the mounting ring 100 during adjustment, but also provides the necessary flexibility for the fine adjustment of the grating lens 700. When adjusting, part of the grating lens 700 can be tilted in the draw hook space 801 of the non-powered end, so as to avoid friction between part of the grating lens 700 and the draw hook assembly 810.

[0089] In the embodiment of the present application, the hinge seat 820 includes a first rotating shaft 821, a second rotating shaft 822 and a connecting strip 823, the first rotating shaft 821 and the second rotating shaft 822 are arranged in space along the radial direction of the limiting ring 500, the first rotating shaft 821 is installed on the guide strip 830, the second rotating shaft 822 is installed on the draw hook piece 812, the first rotating shaft 821 is rotatably connected with one end of the connecting strip 823, and the second rotating shaft 822 is rotatably connected with the other end of the connecting strip 823.

[0090] Specifically, the first rotating shaft 821 is installed on the guide strip 830, and the second rotating shaft 822 is installed on the draw hook piece 812, the first rotating shaft 821 is rotatably connected with one end of the connecting strip 823, and the second rotating shaft 822 is rotatably connected with the other end of the connecting strip 823, so that the draw hook piece 812 can rotate freely during adjustment, thereby improving the flexibility and accuracy of the draw hook mechanism 800. Through the hinge seat 820, the draw hook assembly 810 can effectively cooperate with the guide strip 830 to realize the fine adjustment of the grating lens 700. It ensures that the grating lens 700 can be accurately adjusted in angle when the laser emitter is operating, thereby improving the performance and reliability of the laser positioning system.

[0092] Specifically, the limiting ring 500 is provided with a through groove 502 extending along the axial direction of the limiting ring 500, and the guide bar 830 can slide in the through groove 502. The through groove 502 of the limiting ring 500 provides stable guidance for the guide bar 830, and improves the accuracy of the grating lens 700 during the adjustment process.

The light source 910 is installed on the ring-shaped support 900, and its position corresponds to the grating lens 700, so that the light source 910 can directly irradiate the grating lens 700, ensuring the accuracy of the light transmission path.

[0095] The ring-shaped support 900, the limiting ring 500 and the mounting ring 100 together form a stable frame, which provides a reliable fixed position for the light source 910. This is conducive to reducing the movement or deviation of the light source 910 during operation, ensuring that the light is always aligned with the grating lens 700, and improving the light transmission efficiency.

[0096] In addition, the installation position of the light source 910 matches the position of the grating lens 700. This ensures that the light source 910 can irradiate the grating lens 700 at the optimal angle, maximizes the utilization rate of light, and reduces light loss. This enables the laser positioning system to maintain efficient light transmission in complex environments.
