Description

Technical Field

[0001] The invention relates to the technical field of shield segment manufacturing, and in particular to a segment ring simulation assembly method, device, equipment, system and medium. Background Art

[0002] With the development of tunnel construction technology, shield tunneling has become the mainstream construction technology for tunnel construction. When using the shield method for tunnel construction, prefabricated segments need to be assembled in the shield-formed tunnel to complete the tunnel lining and finally form the tunnel structure. At present, prefabricated segments are usually obtained by injecting concrete into the segment prefabrication mold in the segment prefabrication plant. When using the segment prefabrication mold to manufacture prefabricated segments, it is usually necessary to perform surface quality inspection on the formed segments.

[0003] After the prefabricated segments are manufactured, it is necessary to test whether the prefabricated segments are qualified. In the prefabricated segment qualification test process, whether the prefabricated segments can be assembled into a ring is the main indicator for judging whether the prefabricated segments are qualified. In the prior art, the testing process for whether the prefabricated segments can be assembled into a ring mainly involves actually assembling the prefabricated segments into a ring.

[0004] However, although this assembly process can be used to test the degree of qualification of prefabricated segments, in actual testing, due to the heavy weight of the prefabricated segments themselves, the process of lifting, transporting and assembling is not only time-consuming and labor-intensive, affecting the detection efficiency, but also because each segment needs to be lifted and assembled, resulting in the entire testing process cannot be industrialized or assembly line operation. Summary of the invention

[0005] The main purpose of the present invention is to propose a segment ring simulation assembly method, device, equipment, system and medium, aiming to solve the technical problem that in actual detection, due to the heavy weight of the prefabricated segments themselves, the process of lifting, transporting and assembling is not only time-consuming and labor-intensive, affecting the detection efficiency, but also because each segment needs to be lifted and assembled, resulting in the entire detection process cannot be industrialized or assembly line operation.

[0006] To achieve the above object, the present invention proposes a segment ring simulation assembly method, comprising:

[0007] According to the collected target data sets corresponding to at least six prefabricated segments, a corresponding segment three-dimensional model is established; wherein the target data set is a point cloud data set obtained by scanning the corresponding prefabricated segments using a preset scanning device, and the at least six prefabricated segments include an L1 adjacent block, an L2 adjacent block, a capping block, and at least three standard blocks;

[0008] Determining the installation position of the capping block according to the specific number of blocks required to form the segment ring;

[0009] According to the installation position, determine the target assembly path of the segment ring; wherein the starting point of the target assembly path is the target placement position of the segment three-dimensional model corresponding to any one of the standard rings, and the end point is the installation position;

[0010] According to the target assembly path, the three-dimensional models of the pipe segments corresponding to the prefabricated pipe segments are retrieved in sequence to complete the simulated assembly operation.

[0011] In one embodiment, the step of sequentially retrieving the three-dimensional models of the segments corresponding to the prefabricated segments according to the target assembly path to complete the simulated assembly operation includes:

[0012] According to the target assembly path, the three-dimensional model of the pipe segment corresponding to any of the standard blocks is placed at the target placement position;

[0013] Sequentially assembling the segment 3D models corresponding to the remaining standard blocks, the segment 3D models corresponding to the L1 adjacent blocks, and the segment 3D models corresponding to the L2 adjacent blocks, and making the segment 3D models corresponding to the L1 adjacent blocks and the segment 3D models corresponding to the L2 adjacent blocks located on both sides of the installation position;

[0014] The capping block is installed at the installation position and assembled into the segment ring to complete the simulated assembly operation.

[0016] Installing the capping block at the installation position and assembling it into the segment ring;

[0017] Sequentially obtain the center extension lines of the current hoisting holes corresponding to the three-dimensional models of the segments; wherein the current hoisting holes are arranged in one-to-one correspondence with the preset hoisting holes of the prefabricated segments;

[0018] Extending all the center extension lines into the annular cavity of the segment ring to intersect and form at least one current intersection point;

[0019] Determining whether the intersection positions of all the center extension lines are located at the current intersection point;

[0020] If yes, the simulated assembly operation is completed.

[0021] In one embodiment, after the step of determining whether the intersection positions of all the center extension lines are located at the current intersection point, the method further includes:

[0022] When at least one intersection position is not at the current intersection point, determining whether there is a misalignment between the corresponding segment 3D model and the segment 3D model adjacent thereto;

[0023] When there is no misalignment, the corresponding segment three-dimensional model is replaced and the process returns to the step of determining whether the intersection positions of all the center extension lines are located at the current intersection point. If so, the prefabricated segment corresponding to the replaced segment three-dimensional model is used as a segment with quality defects to complete the simulated assembly operation.

[0024] In one embodiment, after the step of determining whether the corresponding segment 3D model and the segment 3D model adjacent thereto are misaligned when at least one intersection position is not at the current intersection, the method further includes:

[0025] When there is misalignment, the corresponding three-dimensional model of the pipe segment is adjusted until the intersection positions are all located at the current intersection point, completing the simulated assembly operation.

[0026] In one embodiment, before the step of establishing the corresponding segment 3D model according to the target data set corresponding to the at least six prefabricated segments obtained by acquisition, the step further includes:

[0027] Performing positioning operation on the prefabricated pipe segment placed in a preset scanning space, and obtaining the current placement position of the prefabricated pipe segment;

[0028] Control the preset scanning device to move to the current placement position, and perform a scanning operation on the prefabricated pipe segment to collect a target data set of the prefabricated pipe segment; wherein the target data set includes target image data of the prefabricated pipe segment.

[0029] Based on the same technical concept, in a second aspect, the present invention further proposes a segment ring simulation assembly device, comprising:

[0030] A modeling module, used to establish a corresponding three-dimensional model of the pipe segment according to the target data set corresponding to the at least six prefabricated pipe segments obtained by acquisition; wherein the target data set is a point cloud data set obtained by scanning the corresponding prefabricated pipe segment using a preset scanning device, and the at least six prefabricated pipe segments include an L1 adjacent block, an L2 adjacent block, a capping block and at least three standard blocks;

[0032] A path output module, used to determine the target assembly path of the segment ring according to the installation position; wherein the starting point of the target assembly path is the target placement position of the segment three-dimensional model corresponding to any one of the standard rings, and the end point is the installation position;

[0033] The assembly module is used to sequentially retrieve the three-dimensional models of the pipe segments corresponding to the prefabricated pipe segments according to the target assembly path to complete the simulated assembly operation.

[0034] Based on the same technical concept, in the third aspect, the present invention also proposes a segment ring simulation assembly device, which includes a processor and a memory, and a segment ring simulation assembly program is stored in the memory. When the segment ring simulation assembly program is executed by the processor, the segment ring simulation assembly method described in the first aspect is implemented.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0061] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0062] The invention provides a segment ring simulation assembly method.

[0063] See also Figures 1 to 15 In one embodiment of the present invention, the segment ring simulation assembly method comprises:

[0064] S100, establishing a corresponding three-dimensional model of the pipe segment according to the target data set corresponding to the at least six prefabricated pipe segments obtained by acquisition; wherein the target data set is a point cloud data set obtained by scanning the corresponding prefabricated pipe segment using a preset scanning device, and the at least six prefabricated pipe segments include an L1 adjacent block, an L2 adjacent block, a capping block, and at least three standard blocks;

[0065] In this embodiment, it is particularly necessary to clearly state that when assembling the segment ring into a ring, at least six segments are required to form the segment ring. When assembling the ring, one capping block, one L1 adjacent block, one L2 adjacent block and at least three standard blocks are required. If less than six segments are used to assemble the segment ring, it is difficult to form a segment ring. Therefore, in this embodiment, at least six segments are used.

[0066] Of course, in this embodiment, the exemplary preset scanning device is a laser scanning device, and the exemplary preset scanning device includes:

[0067] A connecting member 10, one end of which is detachably connected to an external driving device, and the other end of the connecting member 10 has a mounting seat 20, and the mounting seat 20 can swing around the connecting member 10;

[0068] An image acquisition component 30, the image acquisition component 30 is mounted on the mounting seat 20; and

[0069] The spherical laser cage 40 is arranged around the outer periphery of the image acquisition component 30, and the spherical laser cage 40 is connected to the mounting seat 20. The terminal can control the spherical laser hole to emit a grid-shaped detection laser toward the pipe segment to be inspected to scan each surface of the pipe segment to be inspected, and synchronously control the image acquisition component 30 to follow and collect image data of the corresponding surface scanned by the laser.

[0070] In this embodiment, by providing a connecting member 10, an image acquisition member 30 and a spherical laser cage 40, the spherical laser cage 40 emission mechanism is used to emit a grid-shaped laser to the pipe segment to be inspected, and the image acquisition member 30 is used to scan the area passed by the grid-shaped laser to realize the function of real-time image acquisition of the surface of the pipe segment to be inspected, thereby enabling the present invention to make an instant judgment on the surface quality of the pipe segment to be inspected based on the acquired image and accurately output the inspection results of each position on the pipe segment to be inspected.

[0071] It can be further explained that, in the present embodiment, since the grid-shaped laser emitted by the spherical laser cage 40 is used to scan the surface of the pipe segment to be inspected, and the image acquisition component 30 is used to follow and acquire images during the scanning, the image acquisition component 30 actually acquires the surface of the pipe segment to be inspected and the combined image of the laser beam irradiating the surface of the pipe segment to be inspected. Since the image acquisition component 30 and the spherical laser cage 40 are both installed on the connecting member 10 and move synchronously, the present invention can be used to determine the material and the extension of the laser beam in the image acquired by the image acquisition component 30 through the terminal during specific use, and then determine whether the surface of the corresponding pipe segment to be inspected in the image has quality problems such as cracks, sand holes and ridges.

[0072] It should be particularly and clearly stated that, in this embodiment, the exemplified image acquisition component 30 is preferably a CCD visual camera.

[0073] The exemplary spherical laser cage 40 may be configured to include a connecting frame 41 and a plurality of laser emitters 42, wherein the plurality of laser emitters 42 are connected to the connecting frame 41 at intervals along the circumferential direction. The exemplary laser emitters 42 include:

[0074] The invention comprises a limiting ring 500, a mounting ring 100, a limiting sheet 200, a clamping mechanism 300, a grating lens 700 and a plurality of hook mechanisms 800. The mounting ring 100 is coaxially arranged with the limiting ring 500, and an accommodating 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, the clamping mechanism 300 is arranged opposite to the limiting sheet 200, and the clamping mechanism 300 and the limiting sheet 200 jointly form a clamping space 301; the grating lens 700 is arranged in the clamping space 301, and the clamping mechanism 300 can be moved away from the grating lens 70 along the radial direction of the mounting ring 100. 0 and a clamping position close to the grating lens 700, and correspondingly releases or clamps the grating lens 700; a plurality of hook mechanisms 800 are arranged at intervals along the circumference of the limiting ring 500; each hook mechanism 800 extends along the axial direction of the limiting ring 500, and each hook mechanism 800 has a connecting portion and a hook portion at both ends along its extension direction, and the connecting portion of each hook mechanism 800 is slidably connected to the limiting ring 500 along the axial direction of the limiting ring 500, and the hook portion of each hook mechanism 800 extends into the accommodating space 501 and is detachably connected to the mounting ring 100, and each hook mechanism 800 is used to drive a portion of the mounting ring 100 to tilt toward the limiting ring 500, so as to drive a portion of the grating lens 700 to tilt toward the limiting ring 500.

[0075] Specifically, a plurality of hook mechanisms 800 are arranged at intervals along the circumference of the limiting ring 500, and the connection portion of each hook mechanism 800 can slide along the axial direction of the limiting ring 500, so that the hook mechanism 800 can maintain flexibility during the position and angle adjustment process of the grating lens 700. The hook portion extends into the accommodating space 501 and is detachably connected to the mounting ring 100, ensuring that force can be effectively transmitted during the fine-tuning process and preventing the hook portions from interfering with each other, that is, preventing any hook portion from causing friction and loss between the other hook portion and the mounting ring 100 when driving the mounting ring 100 to tilt, that is, each hook portion is hinged to the mounting ring 100.

[0076] During the implementation process, the hook mechanism 800 can drive part of the mounting ring 100 to tilt toward the limit ring 500, thereby driving the corresponding part of the grating lens 700 to tilt toward the limit ring 500. The fine-tuning accuracy of the grating lens 700 is improved, so that the laser transmitter can more accurately align the target prefabricated segment when performing the laser positioning task, thereby improving the overall performance of the laser positioning system. The reaction speed and accuracy of the laser transmitter can also be flexibly adjusted by setting the number and interval of the hook mechanism 800, and can be adjusted according to the needs of different application scenarios to meet the actual prefabrication requirements of various segments. In addition, the hook mechanism 800 can be slidably connected to the limit ring 500, which also effectively reduces the error caused by improper installation and ensures the stability and accuracy of the grating lens 700.

[0077] In addition, by coaxially arranging the mounting ring 100 and the limiting ring 500 , the formed accommodation space 501 can provide space for making way for the mounting ring 100 and the grating lens 700 during the tilting process.

[0078] It should be noted that the power 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.

[0079] During implementation, 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 to limit the axial displacement of the grating lens 700 on the mounting ring 100; the combined action of the clamping mechanism 300 and the limiting portion 210 limits the radial displacement of the grating lens 700 on the mounting ring 100, and therefore, the position of the grating lens 700 placed in the clamping space 301 is fixed by the limiting piece 200, the mounting ring 100 and the clamping mechanism 300.

[0080] 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 grating lens 700 and a clamping position close to the grating lens 700, so as to quickly install and disassemble the grating lens 700, ensuring that it is firmly clamped during operation and easy to release during maintenance or replacement.

[0081] It should be understood that the setting of 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, 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 grating lens 700, ensuring that the grating lens 700 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 the clamping space 301 together, 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 control of the clamping mechanism 300, which greatly simplifies the installation and replacement process of the grating lens 700 and eliminates the inconvenience and risks brought by the traditional threaded connection method. The operator can complete the release and installation of the grating lens 700 in a shorter time, reducing the loss caused by frequent adjustments, thereby effectively improving work efficiency. Through the coordinated setting of the mounting ring 100, the limit plate 200 and the clamping mechanism 300, the convenience and reliability of the grating lens 700 are significantly improved, which not only improves the stability of the grating lens 700, 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 can slide along the radial direction of the mounting ring 100, so that the grating lens 700 can be easily released or clamped under the control of the clamping mechanism 300, simplifying the installation and replacement process of the grating lens 700 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 grating lens 700 in a shorter time, reducing the wear of components caused by frequent adjustments, effectively improving work efficiency, making the use experience of the laser positioning system smoother, and better meeting the requirements for high precision and high efficiency of prefabricated segments in modern tunnel construction.

[0082] As an optional implementation of this embodiment, the laser transmitter also includes a plurality of vibration damping mechanisms 600, and the plurality of vibration damping mechanisms 600 are alternately arranged with a plurality of hook mechanisms 800; the plurality of vibration damping mechanisms 600 are arranged on the limiting ring 500 at intervals along the circumference of the limiting ring 500, and each vibration damping mechanism 600 extends along the axial direction of the limiting ring 500; the two ends of each vibration damping mechanism 600 along its extension direction are respectively a free end and a connecting end, the connecting end of each vibration damping mechanism 600 is connected to the limiting ring 500, and the free end of each vibration damping mechanism 600 extends into the accommodating space 501 and is connected to the mounting ring 100.

[0083] As an optional embodiment of the vibration reduction mechanism 600, the vibration reduction mechanism 600 includes a connecting seat 610, a compression spring 620 and a clamping jaw assembly 630. The connecting seat 610, the compression spring 620 and the clamping jaw assembly 630 are arranged at intervals along the circumference of the limiting ring 500. The connecting seat 610 is connected to the inner wall of the limiting ring 500 to form a connecting end. One end of the compression spring 620 is connected to the connecting seat 610, and the other end of the compression spring 620 is connected to the clamping jaw assembly 630. The clamping jaw assembly 630 can detachably clamp the outer wall of the mounting ring 100 to form a free end.

[0084] Specifically, the connection seat 610 is connected to the inner wall of the limiting ring 500 to form the connection end of the vibration reduction mechanism 600, thereby ensuring the reliability and stability of the vibration reduction mechanism 600 during operation. One end of the compression spring 620 is connected to the connection seat 610, and the other end is connected to the clamping jaw assembly 630. The function of the compression spring 620 is to provide a moderate elastic force so that the clamping jaw assembly 630 can maintain flexibility and recovery ability when subjected to external vibration, thereby effectively absorbing and buffering vibration.

[0085] More specifically, the clamping jaw assembly 630 is detachably clamped to the outer wall of the mounting ring 100, which improves the convenience of maintenance. When the staff is maintaining or replacing the grating lens 700, the clamping jaw can be quickly released for easy operation without disassembling the entire structure. At the same time, the clamping jaw assembly 630 can firmly clamp the grating lens 700, ensuring that it is not disturbed unnecessarily in the working state, further reducing the risk of wear.

[0086] As another optional implementation of the vibration reduction mechanism 600, the compression spring 620 in the vibration reduction mechanism 600 not only provides a structural basis for the reset of the mounting ring 100 after tilting, but also ensures that the side of the mounting ring 100 facing the limit ring 500 is always kept in a tensioned state. This design enhances the stability of the mounting ring 100 when tilting, thereby improving the tilt control accuracy of the grating lens 700.

[0087] In specific implementation, when a certain hook mechanism 800 hooks one side of the mounting ring 100, the mounting ring 100 will be affected and tilted. Meanwhile, the other unaffected hook mechanisms 800 remain stationary. During the tilting process of the mounting ring 100, the compression spring 620 of the vibration reduction mechanism 600 will apply tension to ensure the stability of the mounting ring 100.

[0088] When the hook mechanism 800 is reset, the compression spring 620 will return to the initial state, so that the mounting ring 100 is also 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, which can effectively reduce the contact area and assembly points between the hook mechanism 800 and the mounting ring 100, and improve the durability of the hook mechanism 800 and the mounting ring 100. The stability and long-term reliability of the laser positioning system during use are ensured, while simplifying the assembly and maintenance process.

[0089] As an optional embodiment of the clamping jaw assembly 630, the clamping jaw assembly 630 includes an arc plate 631 and a limiting bar 632. The limiting bar 632 is L-shaped. One end of the limiting bar 632 is connected to the arc plate 631. The other end of the limiting bar 632 and the arc plate 631 are spaced apart to form an assembly space 601. Part of the mounting ring 100 is arranged in the assembly space 601. The arc plate 631 has a curvature that is compatible with the mounting ring 100.

[0090] Specifically, the limiting strip 632 is L-shaped, one end of which is connected to the arc plate 631 and the other end is spaced apart from the arc 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 the clamping process.

[0091] The assembly space 601 allows part of the mounting ring 100 to be smoothly placed therein, thereby ensuring a good fit between the clamping jaw assembly 630 and the mounting ring 100. The curvature of the arc plate 631 is adapted to the mounting ring 100. This matching design not only enhances the stability of the clamping, but also ensures that the clamping jaw assembly 630 can apply pressure evenly during clamping, thereby reducing potential damage to the grating lens 700. Through the combination of the arc plate 631 and the limit bar 632, the clamping jaw assembly 630 can provide a smooth and reliable operating experience during the clamping and releasing process. Especially when maintaining or replacing the grating lens 700, the user can easily adjust the clamping jaw assembly 630 to achieve quick release or clamping without affecting the overall stability of the laser positioning system.

[0092] In addition, a vibration isolation pad is provided on the side of the limiting strip 632 and the arc plate 631 facing the mounting ring 100 .

[0093] Specifically, the vibration isolation pad can effectively isolate the vibration from the robot arm or other external sources and play a buffering role. The vibration isolation pad is combined with the limit bar 632 and the arc plate 631 to form a multi-level shock absorption system. The vibration isolation pad can further absorb and dissipate the vibration energy and reduce the possibility of them being transmitted to the mounting ring 100 and the grating lens 700.

[0094] In addition, when the clamping jaw assembly 630 clamps the grating lens 700, the vibration isolation pad can provide more uniform pressure and avoid slight displacement caused by vibration, thereby further protecting the accuracy and stability of the grating lens 700.

[0095] In an embodiment of the present invention, the clamping mechanism 300 includes a guide column 310 and a clamping plate 330, and the clamping plate 330 and the limiting plate 200 together form a clamping space 301; the guide column 310 extends along the radial direction of the mounting ring 100, and the guide column 310 is installed on the outer wall of the mounting ring 100, and the clamping plate 330 is slidably installed on the guide column 310, and can move between a release position and a clamping position, correspondingly releasing or clamping the grating lens 700.

[0096] Specifically, the clamping piece 330 and the limiting portion 210 of the limiting piece 200 together form a clamping space 301 for accommodating the grating lens 700. The clamping piece 330 can move between a release position and a clamping position to achieve the release or clamping of the grating lens 700. The guide post 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 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 grating lens 700. 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 grating lens 700.

[0097] In an embodiment of the present invention, the clamping mechanism 300 further includes a radial displacement driving member, which is mounted 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 grating lens 700 accordingly.

[0098] 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 grating lens 700, greatly reducing 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 grating lens 700 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 grating lens 700 can be accurately positioned in the clamping space 301, further enhancing the overall performance of the laser positioning system.

[0099] In an embodiment of the present invention, the clamping mechanism 300 also includes an elastic return member 320 , which is sleeved on the guide column 310 , and one end of the elastic return member 320 is connected to the clamping plate 330 , and the other end of the elastic return member 320 is connected to the mounting ring 100 .

[0100] 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 grating lens 700 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 displacement of the grating lens 700 caused by vibration, and ensure the accuracy and stability of the laser light.

[0101] 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 grating lens 700.

[0102] In an embodiment of the clamping mechanism 300 , a buffer 400 is disposed on both the clamping piece 330 and the side of the limiting portion 210 of the limiting piece 200 facing the grating lens 700 .

[0103] It should be noted that the buffer member 400 is a rubber member in the prior art.

[0104] Specifically, the buffer 400 can effectively absorb the impact force between the clamping piece 330 and the grating lens 700, reduce the damage caused by collision during the clamping or releasing process, and thus protect the grating lens 700 and its optical properties. In addition, during the operation of the laser transmitter, vibration or external impact may occur, and the buffer 400 can provide additional shock absorption effect to ensure that the grating lens 700 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 grating lens 700 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 and tear on the clamping mechanism 300 and the grating lens 700 caused by frequent operations, thereby extending the service life.

[0105] In an embodiment of the limiting piece 200 , there are multiple limiting pieces 200 , 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 .

[0106] Specifically, the plurality of stoppers 200 are distributed along the circumference of the mounting ring 100, which can provide more uniform support for the grating lens 700 when clamping it, ensuring that the grating lens 700 can be stably fixed during the clamping process, reducing local stress concentration. In addition, the provision of the plurality of stoppers 200 makes the adjustment of the clamping space 301 more flexible, and can adapt to grating lenses 700 of different types or sizes, thereby enhancing the compatibility of the laser transmitter.

[0107] 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.

[0108] In an embodiment of the present invention, 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. The axial displacement driving member 840 is connected to the guide bar 830 and is used to drive the guide bar 830 to slide axially along the limiting ring 500, so as to drive a portion of the mounting ring 100 to tilt toward the limiting ring 500, and to make a portion of the grating lens 700 tilt toward the limiting ring 500.

[0109] Specifically, at the beginning of the implementation process, the axial displacement driving member 840 receives a control signal, and after being activated, the axial displacement driving member 840 drives the guide bar 830 to slide along the axial direction 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. As the guide bar 830 moves, the hook assembly 810 tilts through the hinge seat 820, so that the hook assembly 810 can be flexibly rotated 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 part is connected to the mounting ring 100, causing part of the mounting ring 100 to tilt toward the limiting ring 500, thereby causing the corresponding part of the grating lens 700 to tilt toward the limiting ring 500.

[0110] More specifically, the axial displacement driving member 840 can be used to drive the guide bar 830 to perform reciprocating linear motion along the circumference of the mounting ring 100 and the limiting ring 500 , so that the mounting ring 100 drives the grating lens 700 to tilt or reset.

[0111] This embodiment significantly improves the fine-tuning accuracy of the grating lens 700, so that the laser transmitter can be more accurately aligned with the target prefabricated segment when performing the laser positioning task. In addition, the hook mechanism 800 not only enhances the stability during the fine-tuning process, 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.

[0112] In an embodiment of the present invention, the hook assembly 810 includes a mounting plate 811 and a hook member 812. The mounting plate 811 is spaced apart from the inner wall of the mounting ring 100. The hook member 812 is L-shaped. One end of the hook member 812 is connected to the mounting plate 811. The other end of the hook member 812 is spaced apart from the mounting plate 811 to form a hook space 801. Part of the mounting ring 100 is disposed in the hook space 801.

[0113] Specifically, the hook space 801 not only ensures the stability of the mounting ring 100 during the adjustment process, but also provides the necessary flexibility for fine-tuning the grating lens 700. When adjusting, part of the grating lens 700 can be tilted in the hook space 801 at the non-powered end, thereby avoiding friction and loss between part of the grating lens 700 and the hook assembly 810.

[0114] In an embodiment of the present invention, the articulated 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 at radial intervals along the limiting ring 500. The first rotating shaft 821 is installed on the guide strip 830, and the second rotating shaft 822 is installed on the hook member 812. The first rotating shaft 821 is rotatably connected to one end of the connecting strip 823, and the second rotating shaft 822 is rotatably connected to the other end of the connecting strip 823.

[0115] Specifically, the first rotating shaft 821 is mounted on the guide bar 830, and the second rotating shaft 822 is mounted on the hook member 812. The first rotating shaft 821 is rotatably connected to one end of the connecting bar 823, and the second rotating shaft 822 is also rotatably connected to the other end of the connecting bar 823, so that the hook member 812 can rotate freely during the adjustment process, thereby improving the flexibility and accuracy of the hook mechanism 800. Through the hinge seat 820, the hook assembly 810 can effectively cooperate with the guide bar 830 to achieve fine adjustment of the grating lens 700. It ensures that the grating lens 700 can be accurately adjusted in angle when the laser transmitter is in operation, thereby improving the performance and reliability of the laser positioning system.

[0116] In the embodiment of the present invention, a through slot 502 is formed on the limiting ring 500 , and the through slot 502 extends along the axial direction of the limiting ring 500 . The guide bar 830 extends into the through slot 502 and is slidably connected to the limiting ring 500 .

[0117] Specifically, a through groove 502 is formed on the limiting ring 500, and the through groove 502 extends along the axial direction of the limiting ring 500, and the guide bar 830 can slide therein. The through groove 502 structure of the limiting ring 500 provides a stable guide for the guide bar 830, thereby improving the accuracy of the grating lens 700 during the adjustment process.

[0118] In an embodiment of the present invention, the laser emitter also includes a light source 910 and an annular bracket 900. The annular bracket 900 is coaxially arranged with the limiting ring 500. The annular bracket 900 is opposite to the mounting ring 100 and is arranged at intervals. The light source 910 is installed on the annular bracket 900 corresponding to the position of the grating lens 700.

[0119] Specifically, the annular bracket 900 is coaxially arranged with the limiting ring 500, and is opposite to and spaced from the mounting ring 100. The light source 910 is mounted on the annular bracket 900, and its position corresponds to the grating lens 700, so that the light source 910 can directly illuminate the grating lens 700, ensuring that the light transmission path is accurate.

[0120] The annular bracket 900, the limiting ring 500 and the mounting ring 100 together form a stable frame, providing a reliable fixed position for the light source 910. This is beneficial to reduce the movement or offset 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.

[0121] In addition, the installation position of the light source 910 matches the position of the grating lens 700, ensuring that the light source 910 can illuminate the grating lens 700 at the optimal angle, maximizing the light utilization and reducing light loss, so that the laser positioning system can maintain efficient light transmission in complex environments.

[0122] More specifically, based on the axial displacement driver 840 in the above embodiment, the annular bracket 900 also provides a mounting base for the axial displacement driver 840 to ensure that the entire laser transmitter has a compact structure and is easy to use and install.

[0123] As an optional embodiment of the annular bracket 900, the annular bracket 900 includes a plurality of long rods and connecting rings, each of the long rods extending along the axial direction of the limiting ring 500, one end of each limiting rod being connected to the limiting ring 500, and the other end of each limiting rod being connected to the outer wall of the connecting ring, the connecting ring is coaxially arranged with the limiting ring 500 and the mounting ring 100, and the light source 910 is mounted on the connecting ring.

[0124] In addition, a hook mechanism 800 is provided between two adjacent long rods, and the guide bar 830 of the hook mechanism 800 slides with the long rod through the slide groove on the outer wall of the long rod to further improve the sliding stability of the guide bar 830, thereby improving the reliability of the laser positioning system when in use.

[0125] In addition, the light source 910 is a laser light source in the prior art.

[0126] S200, determining the installation position of the capping block according to the specific number of blocks required to form the segment ring;

[0127] In this embodiment, when determining the number of segments required for the segment ring, it can be determined according to the clearance diameter of the assembled tunnel or the shape of the segment ring to be tested. For example, in this embodiment, the number of segments required for the segment ring is six. When the number of segments is six, the installation position of the capping block can be located at the highest point of the segment ring.

[0128] S300, determining a target assembly path of the segment ring according to the installation position; wherein the starting point of the target assembly path is the target placement position of the segment three-dimensional model corresponding to any one of the standard rings, and the end point is the installation position;

[0129] It can be clearly stated that, for example, when assembling the segment ring, it is determined that the first segment at the bottom layer is a standard ring, and one side of it is an L1 adjacent block, and the other side is continuously connected to two standard blocks, and the end of the standard block is connected to the L2 adjacent block on the side away from the second standard block, and the capping block is connected between the L1 adjacent block and the L2 adjacent block, and the capping block is at the installation position. Then, the target assembly path of the segment ring is to place a standard block first, and then place another standard block and the L1 adjacent block at both ends of the first standard block that has been placed. After the assembly is completed, the third standard block, the L2 adjacent block and the capping block are placed in sequence to complete the assembly of the segment ring.

[0130] S400, according to the target assembly path, sequentially retrieve the three-dimensional segment models corresponding to the prefabricated segments to complete the simulated assembly operation.

[0131] In this embodiment, a corresponding three-dimensional model of the segment is established based on the target data set corresponding to at least six prefabricated segments obtained by collection, and the installation position of the capping block is determined according to the specific number of blocks required to form the segment ring. According to the installation position, the target assembly path of the segment ring is determined, and the three-dimensional models of the segment corresponding to each prefabricated segment are called in sequence according to the target assembly path to complete the simulated assembly operation. When used, the present invention establishes a three-dimensional model of the segment according to the target data set obtained by collection, and after determining the target placement and installation position, the segment ring is assembled using the established three-dimensional model of the segment according to the target assembly path. When used, the present invention can complete the assembly operation of the prefabricated segments without actually assembling the prefabricated segments, which does not require consuming time and labor, ensures detection efficiency, and can also achieve industrialization or assembly line operation.

[0132] In one embodiment, step S400 includes:

[0133] S410, placing the segment three-dimensional model corresponding to any of the standard blocks at the target placement position according to the target assembly path;

[0134] In this embodiment, since the standard blocks are segment structures with the same size and specifications, the standard block placed at the target placement position can be any standard block.

[0135] S420, sequentially assembling the segment 3D models corresponding to the remaining standard blocks, the segment 3D models corresponding to the L1 adjacent blocks, and the segment 3D models corresponding to the L2 adjacent blocks, and making the segment 3D models corresponding to the L1 adjacent blocks and the segment 3D models corresponding to the L2 adjacent blocks be located on both sides of the installation position;

[0136] S430, installing the capping block at the installation position and assembling the segment ring to complete the simulated assembly operation.

[0137] In this embodiment, when the capping block is installed at the installation position and assembled into a segment ring, the connection positions of adjacent segments can be connected using a simulated bolt model, or no connection is performed. In specific implementation, it is only necessary to assemble to form a segment ring.

[0138] In one embodiment, step S430 includes:

[0139] S431, installing the capping block at the installation position and assembling the capping block into the segment ring;

[0140] S432, sequentially obtaining the center extension lines of the current hoisting holes corresponding to the three-dimensional models of the segments; wherein the current hoisting holes are arranged in one-to-one correspondence with the preset hoisting holes of the prefabricated segments;

[0141] In this embodiment, the center extension line of the example is the center line of the corresponding hoisting hole, and the center line is a virtual straight line extending along the radial direction of the corresponding segment.

[0142] S433, extending all the center extension lines into the annular cavity of the segment ring to intersect and form at least one current intersection point;

[0143] S434, determining whether the intersection positions of all the center extension lines are located at the current intersection point;

[0144] S435: If yes, the simulated assembly operation is completed.

[0145] In this embodiment, by judging whether all the intersection positions are located at the current intersection point, the present invention can accurately judge whether the sizes, specifications and diameters of the segments are the same when in use. At the same time, since it is judged whether the intersection positions of the center extension lines are located at the same current intersection point, the present invention can accurately judge the smoothness of the assembled segment ring.

[0146] In one embodiment, after step S434, the method further includes:

[0147] S436, when at least one intersection position is not at the current intersection point, determining whether there is a misalignment between the corresponding segment 3D model and the adjacent segment 3D model;

[0148] S437. When there is no misalignment, the corresponding segment three-dimensional model is replaced and the process returns to the step of determining whether the intersection positions of all the center extension lines are located at the current intersection point. If so, the prefabricated segment corresponding to the replaced segment three-dimensional model is used as a segment with quality defects to complete the simulated assembly operation.

[0149] In one embodiment, after step S436, the method further includes:

[0150] S438. When there is misalignment, the corresponding three-dimensional model of the pipe segment is adjusted until the intersection positions are all located at the current intersection point, completing the simulated assembly operation.

[0151] In one embodiment, before step S100, the method further includes:

[0152] S500, performing positioning operation on the prefabricated pipe segment placed in a preset scanning space, and obtaining the current placement position of the prefabricated pipe segment;

[0153] S600, controlling a preset scanning device to move to the current placement position, and performing a scanning operation on the prefabricated pipe segment to collect a target data set of the prefabricated pipe segment; wherein the target data set includes target image data of the prefabricated pipe segment.

[0154] Based on the same technical concept, in a second aspect, the present invention further proposes a segment ring simulation assembly device, comprising:

[0155] A modeling module, used to establish a corresponding three-dimensional model of the pipe segment according to the target data set corresponding to the at least six prefabricated pipe segments obtained by acquisition; wherein the target data set is a point cloud data set obtained by scanning the corresponding prefabricated pipe segment using a preset scanning device, and the at least six prefabricated pipe segments include an L1 adjacent block, an L2 adjacent block, a capping block and at least three standard blocks;

[0156] A position output module, used to determine the installation position of the capping block according to the specific number of blocks required to form the segment ring;

[0157] A path output module, used to determine the target assembly path of the segment ring according to the installation position; wherein the starting point of the target assembly path is the target placement position of the segment three-dimensional model corresponding to any one of the standard rings, and the end point is the installation position;

[0158] The assembly module is used to sequentially retrieve the three-dimensional models of the pipe segments corresponding to the prefabricated pipe segments according to the target assembly path to complete the simulated assembly operation.
