Description

Technical Field

[0001] This utility model relates to the field of shield tunnel segment manufacturing technology, and in particular to a segment capture device and detection system. Background Technology

[0002] With the development of tunnel construction technology, shield tunneling has become the mainstream construction technology for tunnels. When using shield tunneling, precast tunnel segments are assembled inside the shield-formed tunnel to complete the tunnel lining and ultimately form the tunnel structure. Currently, precast tunnel segments are typically produced by injecting concrete into precast molds at a segment prefabrication plant. When using precast molds to manufacture precast tunnel segments, surface quality inspection of the formed segments is usually required.

[0003] In existing technologies, surface quality inspection of precast tunnel segments typically involves manual methods such as surface observation and tapping. However, some technologies utilize 3D scanning equipment in conjunction with segment molds to inspect the forming quality of precast tunnel segments.

[0004] However, while the above-mentioned detection methods can obtain quality inspection results for precast segments to a certain extent, in actual operation, when using existing precast segment surface quality inspection technology to inspect precast segments, there is a problem that the precast segments cannot be accurately captured, making the inspection results susceptible to interference from external factors and affecting the accuracy of the inspection results. Utility Model Content

[0005] The main purpose of this utility model is to propose a segment capture device and detection system, which aims to solve the technical problem that when using existing precast segment surface quality detection technology to detect precast segments in actual operation, the precast segments cannot be accurately captured, resulting in the detection results being easily interfered with by external factors and affecting the accuracy of the detection results.

[0006] To achieve the above objectives, this utility model proposes a segment capture device, comprising:

[0007] terminal;

[0008] A positioning mechanism, wherein the positioning mechanisms are connected end to end to form a placement space, and the positioning mechanism can emit multiple separating light rays into the placement space. The multiple separating light rays can interweave within the placement space to form multiple sequentially adjacent positioning grids. The tube segment to be detected can enter the placement space and cut off the separating light rays passing through it; and,

[0009] A capturing mechanism is disposed above the positioning mechanism. The capturing mechanism is communicatively connected to the terminal. The terminal can control the capturing mechanism to capture the cut-off position of each of the separating light rays and / or any of the positioning positions to determine the placement position of the tube sheet to be tested.

[0010] In one embodiment, the positioning mechanism includes:

[0011] A first positioning component is disposed around the outer periphery of the placement space. A plurality of positioning positions are circumferentially spaced on the top of the first positioning component. The first positioning component also has a plurality of mounting positions spaced apart from the positioning positions. The capturing mechanism can transmit the first spatial coordinates of at least three of the captured and acquired positioning positions to the terminal, so that the terminal can establish a basic coordinate system for the detection space.

[0012] Multiple second positioning components are provided, with the number of second positioning components matching the number of installation positions and arranged in a one-to-one correspondence. Each second positioning component is positioned towards the placement space and can emit separating light rays into the placement space. Multiple separating light rays intersect and interweave in pairs within the placement space to form multiple sequentially adjacent positioning grids. The tube sheet to be tested can enter the placement space and cut off the separating light rays passing through it.

[0013] The capturing mechanism can capture and obtain the second spatial coordinates of the cut-off position of the tube segment to each of the separating rays when the tube segment to be tested cuts off the separating rays. The capturing mechanism can also transmit all the second spatial coordinates to the terminal so that the terminal maps all the second spatial coordinates to the base coordinate system to determine the placement position of the tube segment to be tested.

[0014] In one embodiment, the second positioning component includes:

[0015] Mounting bracket, the mounting bracket being installed at the mounting position; and...

[0016] A first light source assembly is mounted on the mounting base, with the light emitting end of the first light source assembly facing the placement space. The light source generated by the first light source assembly can enter the placement space through the light emitting end to form the separating light.

[0017] In one embodiment, the first light source assembly includes:

[0018] A light source is mounted on the mounting base and is electrically connected to an external power supply.

[0019] A light-concentrating element, wherein the light-concentrating element is disposed on the outer periphery of the light source, and a light-transmitting aperture is formed on the side of the light-concentrating element away from the light source; and,

[0020] A light-transmitting mirror is installed at the light transmission hole, and the light generated by the light source is focused by the light-concentrating element and emitted from the light transmission hole to form the separated light rays.

[0021] In one embodiment, the light-concentrating element protrudes from the position near the light transmission hole in a direction away from the light source so that the light transmission hole forms a light emission channel, the light emission channel is gradually narrowed in a direction away from the light source, and the light-transmitting mirror is installed in the light emission channel.

[0022] In one embodiment, the first positioning component includes:

[0023] Multiple first support bases are distributed circumferentially at intervals around the outer periphery of the placement space;

[0024] A connecting plate, wherein the connecting plates are sequentially connected and disposed on the top of each of the first support bases and are joined end to end to form the placement space, and each of the positioning positions and each of the installation positions are distributed at intervals on the connecting plate; and...

[0025] Multiple positioning posts are provided, with the number of positioning posts matching the number of positioning positions and arranged in a one-to-one correspondence. The terminal can establish a basic coordinate system of the detection space when controlling the capture mechanism to capture at least three of the positioning positions.

[0026] In one embodiment, a plurality of positioning posts are spaced apart on the connecting plate in an inward-outward direction to form at least two positioning rings surrounding the outer periphery of the placement space. Each positioning post includes a first post and a second post. The top surface of the first post is lower than the top surface of the second post. The first posts on the same positioning ring are staggered with the second posts, and the adjacent first posts and second posts on any two adjacent positioning rings are staggered.

[0027] In one embodiment, the capturing mechanism includes:

[0028] A frame, the frame being arranged around the periphery of the positioning mechanism, and the top of the frame extending above the positioning mechanism, the top of the frame being provided with a guide rail;

[0029] A sliding drive component, which is slidably engaged with the guide rail;

[0030] A truss, which is mounted on the sliding drive member, spans across the placement space, and a slide rail spanning across the placement space is provided at the top of the truss.

[0031] A slide block, which is slidably engaged with the slide rail, and the slide block can automatically slide along the slide rail above the placement space;

[0032] A capture component is mounted on the slide block and is positioned facing the placement space. When the sliding drive member drives the truss to slide along the guide rail, the slide block can drive the capture component to slide along the guide rail and capture the tube segment to be detected and / or any of the positioning positions.

[0033] In one embodiment, the capturing assembly includes a rotating frame and a capture device. The rotating frame is mounted on the slide, and the capture device is mounted on the rotating frame. The capture device is positioned facing the placement space, and the rotating frame is used to drive the capture device to rotate. The capture device is capable of capturing the tube segment to be detected and / or any of the positioning positions.

[0034] Based on the same technical concept, in a second aspect, this utility model also proposes a segment detection system that applies the segment capture device described in the first aspect.

[0035] The technical solution of this utility model employs a terminal, a positioning mechanism, and a capturing mechanism. In use, the positioning mechanism emits multiple separating rays into the placement space, causing these rays to interweave and form multiple sequentially adjacent positioning grids. The tube segment to be inspected enters the placement space and intercepts the separating rays passing through it. The capturing mechanism captures the positioning mechanism, thereby determining the first spatial coordinates of the positioning position on the positioning mechanism. A basic coordinate system is established based on the obtained first spatial coordinates. Then, the capturing mechanism captures and obtains the coordinates of the interception positions of each separating ray intercepted by the tube segment to be inspected within the placement space, obtaining multiple second spatial coordinates. These second spatial coordinates are then mapped onto the basic coordinate system to obtain the placement position of the tube segment to be inspected. This allows the utility model to accurately determine the placement position of the tube segment to be inspected within the placement space, providing positional data for subsequent inspection of the tube segment. This ensures that the inspection data contains only the inspection data of the tube segment to be inspected, guaranteeing the accuracy of the inspection results. Attached Figure Description

[0049] This utility model proposes a segment capture device.

[0050] Please see Figures 1 to 6 In one embodiment of this utility model, the tube segment capturing device includes a terminal 100, a positioning mechanism 200, and a capturing mechanism 300. The positioning mechanism 200 has a placement space 210 for placing the tube segment to be detected. The positioning mechanism 200 has a plurality of positioning positions 220 distributed circumferentially. The capturing mechanism 300 is disposed above the positioning mechanism 200 and is communicatively connected to the terminal 100. The capturing mechanism 300 can capture the tube segment to be detected and / or any positioning position 220. The terminal 100 can establish a basic coordinate system of the detection space when controlling the capturing mechanism 300 to capture at least one positioning position 220, and the terminal 100 controls the capturing mechanism 300 to capture the tube segment to be detected located in the basic coordinate system to determine the placement position of the tube segment to be detected.

[0051] In this embodiment, by employing a terminal 100, a positioning mechanism 200, and a capturing mechanism 300, during use, the capturing mechanism 300 captures at least three positioning positions 220 on the positioning mechanism 200 and transmits the first spatial coordinates of each captured positioning position 220 to the terminal 100. This allows the terminal 100 to establish a basic coordinate system based on the acquired multiple first spatial coordinates. Simultaneously, the capturing mechanism 300 can capture the tube segment to be inspected located within the basic coordinate system to determine the placement position of the tube segment to be inspected. This enables the present invention to determine the position of the tube segment to be inspected during specific use, and thus accurately determine the position of the tube segment to be inspected within the placement space 210. This allows the tube segment to be inspected during the inspection process by determining its position within the inspection space based on equipment such as molds. Consequently, the influence of the non-prefabricated tube segment's own structure on the inspection accuracy of the prefabricated tube segment can be avoided, improving the inspection accuracy of the surface quality of the prefabricated tube segment.

[0052] In some specific embodiments, the positioning mechanism 200 includes a first positioning component 230 and a plurality of second positioning components 240. The first positioning component 230 surrounds the outer periphery of the placement space 210. A plurality of positioning positions 220 are distributed circumferentially at intervals on the top of the first positioning component 230. The first positioning component 230 is also provided with a plurality of installation positions 250 distributed at intervals from each positioning position 220. The capturing mechanism 300 can transmit the first spatial coordinates of at least three captured and acquired positioning positions 220 to the terminal 100, so that the terminal 100 can establish a basic coordinate system for the detection space. The number of the plurality of second positioning components 240 is the same as the number of installation positions 250. In a one-to-one configuration, each second positioning component 240 is positioned facing the placement space 210 and can emit separating light rays into the placement space 210. Multiple separating light rays intersect and interweave in pairs within the placement space 210 to form multiple sequentially adjacent positioning grids. The tube to be tested can enter the placement space 210 and cut off the separating light rays passing through it. The capturing mechanism 300 can capture and obtain the second spatial coordinates of the cutting position of each separating light ray of the tube to be tested when the tube to be tested cuts off the separating light rays. The capturing mechanism 300 can transmit all the second spatial coordinates to the terminal 100 so that the terminal 100 maps all the second spatial coordinates to the basic coordinate system and determines the placement position of the tube to be tested.

[0053] In this embodiment, by setting a first positioning component 230 and multiple second positioning components 240, in use, the first positioning component 230 is arranged around the outer periphery of the placement space 210, and multiple positioning positions 220 are distributed circumferentially at intervals on the top of the first positioning component 230. At the same time, the number of second positioning components 240 is the same as the number of positioning positions 220 and they are set one-to-one. The set capture mechanism 300 captures and obtains the first spatial coordinates of at least three first positioning positions 220, and the capture mechanism 300 transmits all the obtained first spatial coordinates to the terminal 100, so that the terminal 100 can establish the basic coordinate system of the placement space 210 based on the received multiple first spatial coordinates. At the same time, the set capture mechanism 300 captures and obtains the second spatial coordinates of the cut-off positions of the tube segment to be tested for each cut-off light when the tube segment to be tested is cut off, and the capture mechanism 300 can transmit all the second spatial coordinates to the terminal 100, so that the terminal 100 can map all the second spatial coordinates onto the basic coordinate system and determine the placement position of the tube segment to be tested. This allows the present invention, in its specific implementation, to utilize the cooperation of the capture mechanism 300, the first positioning component 230, and multiple second positioning components 240 to locate the precast tube segment to be inspected within the placement space 210. This enables the positioning of the precast tube segment within the placement space 210 without the need for molds or other structures, avoiding the drawbacks of external equipment affecting the surface quality inspection accuracy of the precast tube segment and improving the inspection accuracy. Furthermore, since the capture mechanism 300, the first positioning component 230, and the second positioning components 240 have already positioned the precast tube segment within the placement space 210 before inspection, the inspection equipment does not need to search for the precast tube segment within the placement space 210 during surface quality inspection. This reduces the working cycle time of the inspection equipment and improves the inspection efficiency of the precast tube segment surface quality inspection operation.

[0054] It should be specifically and clearly stated that, in this embodiment, when the example second positioning component 240 emits separating rays into the placement space 210, it may emit only one ray into the placement space 210, or it may emit multiple rays spaced apart in the vertical direction simultaneously. In some improved embodiments, the example second positioning component 240 preferably emits multiple separating rays spaced apart in the vertical direction simultaneously. When multiple separating rays are emitted from the same second positioning component 240, each separating ray should be arranged horizontally, and the bottommost separating ray should be aligned with the lowest position of the precast segment, and the topmost position of each separating ray should be aligned with the highest position of the precast segment. Through this arrangement, the present invention can simultaneously determine the height and thickness of the precast segment in specific implementation. Of course, it should be further clarified that, in this embodiment, the way the example second positioning component 240 emits separating rays can directly use existing technology, and no improvements have been made to it in this embodiment. Therefore, it will not be described in detail here.

[0055] Of course, it should also be clarified that when all the second positioning components 240 in this embodiment are capable of emitting multiple beams of dividing light distributed vertically, the top layer of dividing light emitted by all the second positioning components 240 toward the placement space 210 is on the same plane as the highest point of the precast tube, and the bottom layer of dividing light emitted by all the second positioning components 240 toward the placement space 210 is on the same plane as the lowest point of the precast tube.

[0056] In some preferred embodiments, the second positioning component 240 includes a mounting base 241 and a first light source 243 assembly 242. The mounting base 241 is installed at the installation position 250, and the light emitting end of the first light source 243 assembly 242 is arranged facing the placement space 210. The light source 243 generated by the first light source 243 assembly 242 can enter the placement space 210 through the light emitting end to form a separated light.

[0057] In this embodiment, by setting the mounting base 241 and the first light source 243 component 242, the first light source 243 component 242 is installed in the corresponding installation position 250 using the mounting base 241. This allows the present invention to emit scattering light into the placement space 210 using the first light source 243 component 242, which can effectively ensure the stability of the overall structure.

[0058] In some improved embodiments, the first light source 243 component 242 includes:

[0059] Light source 243 is mounted on mounting base 241 and is electrically connected to an external power supply.

[0060] A light-concentrating element 244 is disposed around the outer periphery of the light source 243, and a light-transmitting hole is formed on the side of the light-concentrating element 244 away from the light source 243; and,

[0061] A light-transmitting mirror 245 is installed in the light transmission hole. The light generated by the light source 243 is focused by the light-concentrating element 244 and emitted from the light transmission hole to form a separated light.

[0062] In this embodiment, by setting up a light source 243, a light-concentrating element 244, and a light-transmitting mirror 245, the light source 243, light-concentrating element 244, and light-transmitting mirror 245 ensure that the dividing light entering the placement space 210 has a good focusing effect during use, avoids the scattering of the dividing light, ensures the concentration of the dividing light, and improves the positioning accuracy when positioning the precast tube segments.

[0063] It should be specifically and explicitly stated that, in this embodiment, the example light source 243 is preferably an infrared light source 243 with high focusing density. The example focusing element 244 is preferably a focusing lens.

[0064] In one embodiment, the sidewall of the light transmission hole protrudes in the direction away from the light to form a light emission channel 246, and the light emission channel 246 is gradually narrowed in the direction away from the light source 243. The light transmission lens 245 is installed in the light emission channel 246.

[0065] In this embodiment, by setting a light emission channel 246, the present invention can, during use, use the light emission channel 246 to guide the light focused by the light-concentrating element 244, ensuring the concentration of the separated light rays. Simultaneously, in practical use, multiple light emission channels 246 can be set at vertical intervals, and a light-transmitting mirror 245 can be installed in each light emission channel 246. This allows the present invention to simultaneously inject multiple separated light rays at vertical intervals into the placement space 210, ensuring the stability and uniformity of the separated light rays.

[0066] In one embodiment, the first positioning component 230 includes:

[0067] Multiple first support bases 231 are distributed circumferentially at intervals on the outer periphery of the placement space 210;

[0068] A connecting plate 232 is sequentially connected to the top of each first support base 231 and joined end to end to form a placement space 210. Multiple installation positions 250 are formed on the connecting plate 232 at intervals along the circumference. Each positioning position 220 and each installation position 250 are spaced apart on the connecting plate 232. At least two recessed sections 236 are formed on the connecting plate 232, and these at least two recessed sections 236 are spaced apart along the circumference of the placement space 210.

[0069] Multiple positioning posts 233 are provided, with the number of positioning posts 233 matching the number of positioning positions 220 and each being set in a one-to-one correspondence. When the terminal 100 controls the capture mechanism 300 to capture at least three positioning positions 220, it can establish a basic coordinate system for the detection space. At least two positioning posts 233 are installed on each of the sinking sections.

[0070] In this embodiment, by setting a connecting plate 232, multiple first support seats 231, and multiple positioning posts 233, the connecting plate 232 is installed using the support seats and surrounds the outer periphery of the placement space 210. At the same time, multiple positioning positions 220 and multiple placement positions are distributed at intervals on the connecting plate 232. This allows the positioning posts 233 and the second positioning component 240 to be installed on the connecting plate 232 during use, thereby ensuring that the positioning posts 233 and the second positioning component 240 are in a suspended state. This provides sufficient movement clearance for the precast segments to enter the placement space 210 during use.

[0071] It should be specifically and clearly stated that, in this embodiment, the purpose of setting the sunken section 236 is to improve the coordinate accuracy of the basic coordinate system through the cooperation of the sunken section 236 with the first column 234 and the second column 235 during actual use. It should be further clarified that, in this embodiment, since the sinking depth of the sunken section 236 is settable, when obtaining the first spatial coordinates of the first column 234 and the second column 235, the corresponding first spatial coordinates can be obtained based on the corresponding data and the corresponding number of the first column 234 and the second column 235.

[0072] Of course, it needs to be further clarified that, in this embodiment, the multiple positioning posts 233 are arranged at intervals on the connecting plate 232 in a direction from the inside to the outside to form at least two positioning rings surrounding the placement space 210. Each positioning post 233 includes a first post 234 and a second post 235. The top surface of the first post 234 is lower than the top surface of the second post 235. The first post 234 and the second post 235 on the same positioning ring are staggered, and the adjacent first post 234 and the second post 235 on any two adjacent positioning rings are staggered.

[0073] In this embodiment, the positioning post 233 is set as a first post 234 and a second post 235, and the top surface of the first post 234 is lower than the top surface of the second post 235. At the same time, the first post 234 and the second post 235 are staggered. In the end, the present invention can achieve the function of establishing a basic coordinate system of three-dimensional state by capturing and obtaining the spatial coordinates of the first post 234 and the second post 235 in specific implementation.

[0074] In one embodiment, the capturing mechanism 300 includes:

[0075] The frame 310 surrounds the positioning mechanism 200, and the top of the frame 310 extends above the positioning mechanism 200. A guide rail 320 is provided on the top of the frame 310.

[0076] The sliding drive component 330 is in sliding engagement with the guide rail 320;

[0077] Truss 340 is mounted on sliding drive member 330. Truss 340 spans above placement space 210, and top of truss 340 is provided with slide rail 350 spanning above placement space 210. Sliding drive member 330 can drive truss 340 to slide along guide rail 320.

[0078] Slide 360, slide 360 ​​slidingly engages with slide rail 350; and...

[0079] The capture component 370 is mounted on the slide 360 ​​and is positioned facing the placement space 210. The capture component 370 is communicatively connected to the terminal 100. The slide 360 ​​drives the capture component 370 to slide automatically along the slide rail 350 above the placement space 210.

[0080] The capture component 370 can capture and obtain the second spatial coordinates of the cut-off position of each dividing light of the tube segment to be tested when the dividing light of the tube segment to be tested is cut off, and the capture mechanism 300 can transmit all the second spatial coordinates to the terminal 100 so that the terminal 100 can map all the second spatial coordinates onto the basic coordinate system to determine the placement position of the tube segment to be tested.

[0081] In one embodiment, the capture assembly 370 includes a rotating frame 371 and a capture device 372. The rotating frame 371 is mounted on a slide 360, and the capture device 372 is mounted on the rotating frame 371. The capture device 372 is communicatively connected to the terminal 100. The capture device 372 is positioned facing the placement space 210, and the rotating frame 371 is used to drive the capture device 372 to rotate. The capture device 372 can capture and obtain the second spatial coordinates of the cutoff position of each dividing light of the tube segment to be tested when the segment to be tested cuts off the dividing light. The capture mechanism 300 can transmit all the second spatial coordinates to the terminal 100 so that the terminal 100 maps all the second spatial coordinates to the basic coordinate system to determine the placement position of the tube segment to be tested.

[0082] It should be specifically and clearly stated that, in this embodiment, the example capture device 372 is preferably a device or apparatus in the prior art capable of realizing light capture and position measurement functions. In this embodiment, it is only applied and its own structure has not been improved. Therefore, it will not be described in detail here. Of course, in the exemplary embodiment, in order to record the movement of the truss 340 driven by the sliding drive member 330, in specific implementation, a plurality of equidistantly distributed positioning blocks 236 are also provided on one side of the guide rail 320 on the frame 310. In specific operation, the set capture device 372 can be used to capture the positioning blocks 236 in real time to achieve the purpose of quickly determining the specific position of the truss 340.

[0083] Of course, in this embodiment, it can be further clarified and explained that the example capture device 372 may be, but is not limited to, a tilt camera or a CCD vision camera in the prior art.

[0084] Of course, in order to enable those skilled in the art to further understand this utility model, in this embodiment, the specific workflow is as follows:

[0085] First, the tube segment to be inspected is transported to the placement space 210. Then, the sliding drive 330 is controlled to drive the truss 340 to slide along the guide rail 320 to the top of one side of the tube segment to be inspected. Next, the slide block 360 installed on the truss 340 is used to drive the capture component 370 to slide along the slide rail 350 to the corner position of the corresponding side of the tube segment to be inspected. At this corner position, the capture component 370 is controlled by the terminal 100 to capture and obtain at least three positioning posts 233 in the area where the tube segment to be inspected is located. When the first spatial coordinates of at least three positioning posts 233 are acquired, the terminal 100 is used to establish a basic coordinate system applicable to the placement space 210. Next, the capture component 370 is controlled to capture and obtain the cut-off positions of each dividing light ray of the tube segment to be inspected located in the basic coordinate system. Then, the placement position of the tube segment to be inspected in the placement space 210 can be determined based on the obtained cut-off positions.

[0086] It should be specifically and clearly stated that, in this embodiment, the specific process of obtaining the cutoff position of each separating ray is as follows: the capture component 370 is set as an oblique photography camera. In use, the sliding drive component 330 drives the truss 340 and the slide 360 ​​to transmit the movement stroke of the capture component 370 to the terminal 100. Then, the terminal 100 uses the length of each separating ray determined by the capture component 370 to the corresponding cutoff position to determine the coordinates of the cutoff position, and then determines the coordinates of each cutoff position. By combining the coordinates of all cutoff positions, the second spatial coordinates are obtained, and the placement position of the tube segment to be detected is determined.
