Description

Technical Field

[0002] During the construction process, the accuracy of shield segment prefabrication is crucial to the overall quality and safety of the project. With the advancement of technology, laser positioning systems are gradually being used in the shield segment prefabrication process due to their high accuracy and repeatability.

[0003] Currently, laser positioning systems are commonly calibrated using laser rangefinders and 3D scanners during the prefabrication of shield segments. These systems can guide workers in construction through high-precision laser projection technology, and monitor the shape and position of shield segments in real time during the production process. Although modern laser positioning systems have significantly improved positioning accuracy and efficiency, in actual applications, manual intervention is still required for initial calibration and regular adjustments. In addition, although laser projection systems can achieve relatively accurate positioning, they still need to be calibrated frequently due to environmental factors to maintain continuous measurement accuracy. In this process, the installation process of the calibration mirror is particularly important because it directly affects the accuracy of laser light correction.

[0033] During the construction process, the accuracy of shield segment prefabrication is crucial to the overall quality and safety of the project. With the advancement of technology, laser positioning systems are gradually being used in the shield segment prefabrication process due to their high accuracy and repeatability.

[0034] Currently, laser positioning systems are commonly calibrated using laser rangefinders and 3D scanners during the prefabrication of shield segments. These systems can guide workers in construction through high-precision laser projection technology, and monitor the shape and position of shield segments in real time during the production process. Although modern laser positioning systems have significantly improved positioning accuracy and efficiency, in actual applications, manual intervention is still required for initial calibration and regular adjustments. In addition, although laser projection systems can achieve relatively accurate positioning, they still need to be calibrated frequently due to environmental factors to maintain continuous measurement accuracy. In this process, the installation process of the calibration mirror is particularly important because it directly affects the accuracy of laser light correction.

[0035] However, the installation method of the calibration mirror in the laser positioning system is relatively cumbersome, and usually adopts a threaded connection method. Although the threaded connection method of the calibration mirror in the laser positioning system can provide a certain stability, it is easy to cause damage to the calibration mirror during the removal and replacement process. In addition, the frequent calibration needs increase labor costs and operational complexity, and reduce overall work efficiency. Under high-frequency use, the durability and stability of the calibration mirror are not effectively guaranteed, which may lead to instability and potential safety hazards during the calibration process.

[0036] In order to solve this technical problem, the present invention proposes a laser light correction system.

[0037] See also Figure 1 and Figure 2 In one embodiment of the present invention, the laser light correction system includes a mounting ring 100, a limiting plate 200, a clamping mechanism 300 and a calibration mirror, wherein the limiting plate 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, the clamping mechanism 300 and the limiting plate 200 are arranged opposite to each other, and the clamping mechanism 300 and the limiting plate 200 jointly form a clamping space 301; the calibration mirror 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 calibration mirror and a clamping position close to the calibration mirror, and correspondingly releases or clamps the calibration mirror.

[0038] It should be noted that the power source for adjusting the clamping mechanism 300 between the release position away from the calibration mirror and the clamping position close to the calibration mirror is manual adjustment or a driving motor in the prior art.

[0039] Specifically, when the calibration mirror is installed in the clamping space 301, the edge of the calibration mirror is located on the limiting plate 200 and is abutted by the mounting ring 100 to limit the axial displacement of the calibration mirror on the mounting ring 100; the combined action of the clamping mechanism 300 and the limiting portion 210 limits the radial displacement of the calibration mirror on the mounting ring 100, and therefore, the position of the calibration mirror placed in the clamping space 301 is fixed by the limiting plate 200, the mounting ring 100 and the clamping mechanism 300.

[0040] More specifically, the clamping mechanism 300 can move radially along the mounting ring 100, and can be adjusted between a release position away from the calibration mirror and a clamping position close to the calibration mirror, so as to quickly install and disassemble the calibration mirror, ensuring that it is firmly clamped during operation and easy to release during maintenance or replacement.

[0041] It should be understood that the setting of the mounting ring 100 provides a stable base for the calibration mirror, and the limiting piece 200 thereon can provide a stable mounting point, thereby enhancing the stability and accuracy of the calibration mirror. The limiting piece 200 enables the calibration mirror to be reliably positioned in the clamping space 301, avoiding the light deviation caused by vibration or other external forces when the laser positioning system is working, thereby improving the overall correction effect. In addition, the clamping mechanism 300 is slidably arranged on the mounting ring 100 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 the operator to make quick adjustments. In actual operation, the clamping mechanism 300 can effectively control the clamping force of the calibration mirror, ensuring that the calibration mirror will not be damaged due to excessive pressure during the clamping process. At the same time, the clamping mechanism 300 and the limiting piece 200 are arranged relative to each other to form a clamping space 301 together, further ensuring the stability of the calibration mirror. In addition, the calibration mirror is arranged in the clamping space 301 and can be released or clamped under the control of the clamping mechanism 300, which greatly simplifies the installation and replacement process of the calibration mirror and eliminates the inconvenience and risks brought by the traditional threaded connection method. The operator can complete the release and installation of the calibration mirror in a shorter time, reducing the loss caused by frequent adjustments, thereby effectively improving work efficiency.

[0042] In the technical solution provided by the present invention, the convenience and reliability of the calibration mirror are significantly improved through the coordinated setting of the mounting ring 100, the limit plate 200 and the clamping mechanism 300, which not only improves the stability of the calibration mirror, but also enhances its accuracy during calibration operations, effectively preventing the laser positioning system from causing light deviation due to vibration or external force interference during operation, thereby improving the correction effect of the laser light of the laser positioning system. At the same time, the clamping mechanism 300 is slidable along the radial direction of the mounting ring 100, so that the calibration mirror can achieve a simple release or clamping process under the control of the clamping mechanism 300, simplifying the installation and replacement process of the calibration mirror, and eliminating the complexity and potential risks brought by the traditional threaded connection method. In addition, the operator can complete the installation and release of the calibration mirror in a shorter time, reduce the wear of components caused by frequent adjustments, effectively improve work efficiency, make the use experience of the laser positioning system smoother, and better meet the requirements of high precision and high efficiency of prefabricated shield segments in modern construction.

[0043] Please continue to refer to Figure 1 and Figure 2In an embodiment of the present invention, the clamping mechanism 300 includes a guide column 310 and a clamping plate 330. The clamping plate 330 and the limiting plate 200 together form a clamping space 301. The guide column 310 extends radially along the mounting ring 100. The guide column 310 is installed on the outer wall of the mounting ring 100. The clamping plate 330 is slidably installed on the guide column 310 and can move between a release position and a clamping position to release or clamp the calibration mirror accordingly.

[0044] Specifically, the clamping piece 330 and the limiting portion 210 of the limiting piece 200 together form a clamping space 301 for accommodating the calibration mirror. The clamping piece 330 can move between a release position and a clamping position to achieve the release or clamping of the calibration mirror. The guide post 310 extends radially along the mounting ring 100 and is mounted on the outer wall of the mounting ring 100. The clamping piece 330 can be slidably mounted on the guide post 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 calibration mirror. The elastic reset member 320 is sleeved on the guide post 310 and is located between the clamping piece 330 and the mounting ring 100. To provide elastic force, the clamping piece 330 automatically returns to the preset position after release, ensuring that the clamping piece 330 can stably clamp the calibration mirror.

[0045] In an embodiment of the present invention, the clamping mechanism 300 also includes a radial displacement driving member, which is installed on the mounting ring 100. The radial displacement driving member is connected to the clamping plate 330 and is used to drive the clamping plate 330 to move between a release position and a clamping position, thereby releasing or clamping the calibration mirror accordingly.

[0046] Specifically, the radial displacement drive provides power support for the clamping mechanism 300, so that the operator can quickly adjust the position of the clamping piece 330 through simple operations, and can easily complete the clamping or release of the calibration mirror, which greatly reduces the complexity and time cost of manual operation. In addition, the radial displacement drive also ensures the stability of the clamping piece 330 during the movement process, avoiding damage to the calibration mirror due to unnecessary shaking during clamping or release. In addition, the use of the radial displacement drive also effectively improves the accuracy of the operation, so that the calibration mirror can be accurately positioned in the clamping space 301, further enhancing the overall performance of the laser positioning system.

[0047] Please continue reading Figure 1 and Figure 2 In an embodiment of the present invention, the clamping mechanism 300 also includes an elastic reset member 320, which is sleeved on the guide column 310, and one end of the elastic reset member 320 is connected to the clamping sheet 330, and the other end of the elastic reset member 320 is connected to the mounting ring 100.

[0048] Specifically, the provision of the elastic reset member 320 greatly enhances the automation function of the clamping mechanism 300. When the operator moves the clamping plate 330 to the release position, the elastic reset member 320 will restore the clamping plate 330 to the clamping position through its elastic properties. This automatic reset function not only reduces the operator's manual intervention and improves work efficiency, but also ensures that the calibration mirror will not fall off due to accidental collision in the non-clamped state. In addition, the elastic reset member 320 can absorb external shocks or vibrations, further enhancing the stability of the clamping plate 330, so as to effectively avoid the position deviation of the calibration mirror caused by vibration, and ensure the accuracy and stability of the laser light.

[0049] 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. In this embodiment, the guide column 310 is used to provide a stable sliding path for the clamping piece 330, and combined with the deformation reset function of the elastic reset member 320, it is ensured that the clamping piece 330 can be quickly and reliably moved to the desired position, thereby enhancing the convenience and stability of the assembly and disassembly operation of the calibration mirror.

[0050] In the embodiment of the present invention, a buffer member 400 is provided on both the clamping piece 330 and the limiting portion 210 of the limiting piece 200 facing the calibration mirror.

[0051] It should be noted that the buffer member 400 is a rubber member in the prior art.

[0052] Specifically, the buffer 400 can effectively absorb the impact force between the clamping piece 330 and the calibration mirror, reduce the damage caused by collision during the clamping or releasing process, and thus protect the calibration mirror and its optical properties. In addition, during the operation of the laser transmitter, vibration or external shock may occur, and the buffer 400 can provide additional shock absorption effect to ensure that the calibration mirror always maintains a stable working state. In addition, by using the buffer 400 to provide a soft contact surface during the clamping process, it helps to prevent the calibration mirror from being offset or inaccurately positioned during the clamping process, thereby improving the overall calibration accuracy of the laser positioning system. In addition, the use of the buffer 400 can reduce the wear on the clamping mechanism 300 and the calibration mirror caused by frequent operations, thereby extending the service life.

[0053] In the embodiment of the present invention, there are multiple limiting pieces 200 , which 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 .

[0054] Specifically, multiple stoppers 200 are distributed along the circumference of the mounting ring 100, which can provide more uniform support for the calibration mirror when clamping it, ensuring that the calibration mirror can be stably fixed during the clamping process and reducing local stress concentration. In addition, the provision of multiple stoppers 200 makes the adjustment of the clamping space 301 more flexible, and can adapt to calibration mirrors of different types or sizes, thereby enhancing the compatibility of the laser transmitter.

[0055] It should be noted that the relative setting in this embodiment refers to the relative positional relationship, including but not limited to a symmetrical relationship. The relative setting may also refer to the setting of the clamping piece 330 relative to the gap between two adjacent limiting pieces 200.

[0056] In an embodiment of the present invention, the calibration mirror includes a frame 90 and a calibration mirror body 80, the frame 90 is arranged on the calibration mirror body 80 along the circumferential frame of the calibration mirror body 80, and the frame 90 and the calibration mirror body 80 are both arranged in the clamping space 301; the outer wall of the mounting ring 100 is recessed to form a slot 101, and a protrusion is provided at a position of the frame 90 corresponding to the slot 101, and the protrusion extends into the slot 101 and is detachably connected to the slot 101.

[0057] Specifically, the frame 90 provides additional support for the calibration mirror body 80, which helps prevent the calibration mirror body 80 from being displaced due to external forces during operation. In addition, the shape design of the frame 90 can increase the impact resistance of the calibration mirror, ensuring that it can still maintain good performance under high-frequency use. The cooperation between the frame 90 and the calibration mirror body 80 enables the entire calibration mirror to form a compact and stable unit in the clamping space 301.

[0058] At the same time, the outer wall of the mounting ring 100 is recessed to form a slot 101, and a protrusion is provided at the position of the frame 90 corresponding to the slot 101. The protrusion extends into the slot 101 and is detachably connected to the slot 101, further improving the stability of the calibration mirror, not only facilitating the rapid installation and removal of the calibration mirror, but also ensuring a firm connection while avoiding wear or damage caused by long-term use. The operator can easily fix the calibration mirror in the clamping space 301, ensuring its stability and accuracy when the laser positioning system is working.

[0059] In an embodiment of the present invention, there are multiple slots 101 , which are spaced apart along the circumference of the mounting ring 100 , and there are multiple protrusions, which are consistent with the number of slots 101 and are arranged one-to-one.

[0060] Specifically, there are multiple slots 101, and the multiple slots 101 are evenly spaced along the circumference of the mounting ring 100, so that the calibration mirror can be flexibly fixed at multiple positions, increasing the flexibility and adaptability of installation. At the same time, the setting of multiple slots 101 can meet the needs of different application scenarios, allowing operators to select the most suitable installation position according to specific circumstances, thereby further improving the stability and accuracy of the calibration mirror.

[0061] Correspondingly, the number of the protrusions is also multiple, and is consistent with the number of the card slots 101, forming a one-to-one corresponding structure, ensuring that each card slot 101 has a corresponding protrusion for fixing, avoiding the problem of unstable installation caused by insufficient or excessive number of protrusions. Through this corresponding relationship, when installing the calibration mirror, the operator can quickly and accurately align the protrusion with the card slot 101 to achieve a stable connection. Therefore, this embodiment not only improves the convenience of installation of the calibration mirror, but also enhances its safety during operation. Whenever the calibration mirror is connected to the card slot 101 through the corresponding protrusion, it can not only firmly fix the position, but also effectively resist external forces during the operation of the laser positioning system, preventing the calibration mirror from being displaced or damaged due to vibration.

[0062] Please continue to refer to Figure 1 , and refer to Figure 3 and Figure 4 In the embodiment of the present invention, the calibration mirror body 80 includes a first strip mirror body 10, a second strip mirror body 20, a first grating 40 and a second grating 50. The first strip mirror body 10 extends in the longitudinal direction to form a first calibration interval 11. The first strip mirror body 10 has a first curved side 12 and a straight side 13 on both sides of its extension direction. The second strip mirror body 20 extends in the transverse direction to form a second calibration interval 21. Part of the first calibration interval 11 overlaps with part of the second calibration interval 21 to form a third calibration interval 30. The second strip mirror body 20 has a second curved side 12 and a straight side 13 on both sides of its extension direction. The arcuate side 22 and the third arcuate side 23, the second arcuate side 22 and the third arcuate side 23 have the same curvature, and the second arcuate side 22 and the first arcuate side 12 have different curvatures; the first grating 40 extends longitudinally, the first grating 40 is arranged between the first arcuate side 12 and the straight side 13, and is located in the first calibration interval 11; the second grating 50 extends transversely, the second grating 50 is arranged between the second arcuate side 22 and the third arcuate side 23, the second grating 50 is located in the second calibration interval 21, and a portion of the first grating 40 and a portion of the second grating 50 intersect in the third calibration interval 30.

[0063] It should be noted that Figure 4 The dotted boxes in are only used to illustrate the ranges of the first calibration interval 11 , the second calibration interval 21 and the third calibration interval 30 .

[0064] It should be understood that the clamping piece 330 is spaced apart from the first curved side 12 of the first strip mirror body 10, and the clamping piece 330 has a curvature that matches the first curved side 12. When the clamping piece 330 is manually pulled up from the clamping position to the release position, the spring is in a stretched state, and the first strip mirror body 10 and the second strip mirror body 20 are placed in the clamping space 301, so that the second curved side 22 and the third curved side 23 of the second strip mirror body 20 are respectively abutted against the limiting portions 210 of the two limiting pieces 200; when the clamping piece 330 is released, the spring is reset to drive the clamping piece 330 to move from the release position to the clamping position, thereby clamping the first strip mirror body 10 and the second strip mirror body 20 in the clamping space 301, so as to simplify the disassembly and assembly process of the calibration mirror and improve the prefabrication production efficiency of the shield segment.

[0065] Specifically, the first strip mirror 10 and the first grating 40 together form a calibration area of ​​the longitudinal strip light path. The first grating 40 is arranged in the longitudinal direction, and guides the light to form a stable longitudinal strip light path through its tiny structural interval. The first calibration interval 11 is used to calibrate the longitudinal strip light path.

[0066] Similarly, the second grating 50 of the second strip-shaped mirror body 20 is arranged in the transverse direction, and generates a transverse strip light path through its tiny structural interval. The second calibration interval 21 is used to calibrate the transverse strip light path.

[0067] At the intersection of the first grating 40 and the second grating 50, a third calibration section 30 of the grid-shaped optical path is formed. This area utilizes the combination of the first grating 40 and the second grating 50 to achieve multi-dimensional optical path calibration. The crossed grating structure allows the light to be adjusted and corrected in both the vertical and horizontal directions, ensuring high-precision transmission of light in a complex optical path layout.

[0068] More specifically, the first curved side 12 of the first strip mirror body 10 can change the propagation path of the light, and by adjusting the curvature of the first strip mirror body 10, the light can be guided to pass through the calibration area more accurately when passing through the first strip mirror body 10. It can be understood that the second curved side 22 and the third curved side 23 of the second strip mirror body 20 have the same function as the first curved side 12.

[0069] In addition, the curvature of the first curved side 12 is different from that of the second curved side 22, and the influence of the edges of the mirror body with different curvatures on the optical path is calibrated. The synergy of the first curved side 12, the second curved side 22, the third curved side 23, the first grating 40, and the second grating 50 is not only a simple path adjustment, but also a comprehensive calibration of the light, which can significantly improve the accuracy of the optical path. It ensures that the light can be transmitted along the optimal path under a complex optical path layout, greatly reducing the error of the laser positioning system and improving the overall calibration effect.

[0070] This embodiment realizes multi-dimensional optical path calibration in a limited space by forming a first calibration interval 11, a second calibration interval 21 and a third calibration interval 30 by the first strip mirror body 10 and the second strip mirror body 20, and by using the combination of the first grating 40 and the second grating 50. The first arc side 12 is combined with the longitudinal grating to calibrate the longitudinal optical path transmission error. The second strip mirror body 20 forms a stable transverse optical path through the second arc side 22, the third arc side 23 and the transverse grating to calibrate the transmission error of the transverse optical path. In the intersection area of ​​the first grating 40 and the second grating 50, that is, the third calibration interval 30, the combination of the longitudinal optical path and the transverse optical path forms a calibration interval of the grid-like optical path, providing a multi-dimensional optical path calibration capability. The first arc side 12 and the second arc side 22 of different curvatures correct the influence of the edge of the mirror body on the optical path, further improving the accuracy of optical path transmission. Through the synergistic effect of the above-mentioned structures, the present invention can not only meet the calibration requirements of various laser optical paths through a calibration mirror, but also improve the accuracy and reliability of the overall laser positioning system, thereby greatly improving the quality of finished products and production efficiency during the prefabrication process of shield segments.

[0071] As an optional implementation of the calibration mirror, the first grating 40 includes a plurality of first grating bars 41 , one end of each first grating bar 41 abuts against the first arcuate side 12 , and the other end of each first grating bar 41 abuts against the straight side 13 .

[0072] Specifically, the first grating 40 includes a plurality of first grid bars 41, one end of each first grid bar 41 abuts against the first curved side 12, and the other end of each first grid bar 41 abuts against the straight side 13. The first grating 40 can provide a stable guiding effect when light passes through. At the same time, the abutment between the straight side 13 and the first grid bars 41 ensures that the light can maintain a straight line when passing through the grating. The first grating 40 realizes the calibration process of the light in the first calibration interval 11 in the longitudinal direction through the arrangement of the plurality of first grid bars 41, and utilizes the light refraction characteristics of the first curved side 12 and the light reflection characteristics of the straight side 13, so that the light can stably propagate within the preset path, thereby realizing accurate optical path calibration.

[0073] Please continue reading Figure 3 As another optional implementation of the calibration mirror, the second grating 50 includes a plurality of second grating bars 51 , one end of each second grating bar 51 abuts against the second arc-shaped side 22 , and the other end of each second grating bar 51 abuts against the third arc-shaped side 23 .

[0074] Specifically, when the light contacts the contact points between the second grid bars 51 and the second curved side 22 and the third curved side 23, the propagation path of the light is adjusted so that the light maintains the preset refraction angle in the lateral direction. The interaction between the second curved side 22 and the third curved side 23 ensures that the light can adapt to the preset refraction angle when entering the second grating 50. The second grating 50 realizes the calibration process of the light in the second calibration interval 21 through the arrangement of the plurality of second grid bars 51.

[0075] Please continue reading Figure 3 As another optional implementation of the calibration mirror, the first strip-shaped mirror body 10 and the second strip-shaped mirror body 20 intersect to form a T-shaped structure.

[0076] Specifically, the intersection of the first strip-shaped mirror body 10 and the second strip-shaped mirror body 20 is the third calibration interval 30 , and the second calibration interval 21 formed by the second strip-shaped mirror body 20 is located on two opposite sides of the third calibration interval 30 .

[0077] More specifically, in the third calibration interval 30, multi-dimensional optical path adjustment is achieved. The longitudinal calibration function of the first strip mirror body 10 is combined with the lateral calibration function of the second strip mirror body 20 to form a stable optical path intersection. The second calibration intervals 21 located on opposite sides of the third calibration interval 30 further expand the control range of the optical path. Through the extension of the second strip mirror body 20, multiple second calibration intervals 21 also provide additional calibration capabilities for the optical path calibration process, meeting the calibration of complex optical paths.

[0078] As another optional implementation of the calibration mirror, the first strip mirror body 10 and the second strip mirror body 20 are integrally formed. The stability of the overall structure of the calibration mirror is enhanced, and when the light passes through the integrally formed first strip mirror body 10 and the second strip mirror body 20, a continuous and consistent calibration effect can be obtained, without being affected by the connection between the first strip mirror body 10 and the second strip mirror body 20 to generate errors.

[0079] In addition, the integrally formed first strip-shaped mirror body 10 and second strip-shaped mirror body 20 simplifies the manufacturing process of the calibration mirror, reduces the assembly steps, thereby reducing production costs and time, and significantly improves the stability and accuracy of the optical path, thereby improving the reliability of the calibration results of the laser positioning system.

[0080] In an embodiment of the present invention, the frame 90 includes a first outer frame 60 and a second outer frame 70. The first outer frame 60 is arranged outside the first strip mirror body 10, and the second outer frame 70 is arranged outside the second strip mirror body 20. The first outer frame 60 intersects with the second outer frame 70, and the intersection of the first outer frame 60 and the second outer frame 70 is connected. The first outer frame 60 and the second outer frame 70 are both provided with protrusions on the side facing the mounting ring 100.

[0081] Specifically, the first outer frame 60 and the second outer frame 70 provide stable support and protection for the first strip mirror body 10 and the second strip mirror body 20, respectively, thereby enhancing the durability of the calibration mirror and reducing the adverse effects of the external environment on the optical path calibration process.

[0082] More specifically, the first outer frame 60 and the second outer frame 70 are both provided with a bump on one side facing the mounting ring 100. The bump not only strengthens the connection, but also matches with the card slot 101 of the mounting ring 100, further ensuring a firm connection between the frame 90 and the mounting ring 100, so that the calibration mirror can maintain a good position in the clamping space 301, and prevents displacement caused by vibration or external force.

[0083] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
