Description

Technical Field

[0001] This invention relates to the field of tunnel engineering technology, and in particular to an integrated equipment for rapid detection and maintenance of the entire cross-section of tunnel engineering. Background Technology

[0002] During tunnel construction, blasting is carried out first, and then laser detection is performed on the entire tunnel cross-section after blasting to identify areas with excessive protrusions in the tunnel cross-section. These areas are then promptly repaired and maintained to ensure the initial support and other subsequent work after blasting.

[0003] In the current process of full-section tunnel inspection, only laser or radar can be used to locate the protruding parts of the tunnel section after blasting that exceed the set range. However, it is impossible to use the detection information in a timely and accurate manner to simultaneously mark and display the position of each protruding part that exceeds the range during on-site construction. This brings certain difficulties to the subsequent construction personnel in repairing and maintaining the protruding parts of the tunnel section and greatly reduces the construction efficiency of other construction procedures after blasting. Summary of the Invention

[0004] This invention provides an integrated equipment for rapid full-section inspection and maintenance of tunnel engineering. It solves the problem that in the existing technology, when conducting full-section inspection of tunnels, only laser or radar can be used to locate the protruding parts of the tunnel section after blasting that exceed the set range. However, it is impossible to use the detection information in a timely and accurate manner to simultaneously mark and display the position of each protruding part that exceeds the range during on-site construction. This makes it difficult for subsequent construction personnel to repair and maintain the protruding parts of the tunnel section and greatly reduces the construction efficiency of other maintenance procedures after blasting.

[0005] To achieve the above and other related objectives, this invention provides an integrated equipment for rapid full-section detection and maintenance of tunnel engineering, comprising: a support assembly with a guide rail corresponding to the shape of the tunnel cross-section; a detection traction component mounted on the support assembly and slidably disposed within the guide rail for rotating and detecting the distance value between itself and the tunnel cross-section, and the detection position of the detection traction component corresponding to each distance value; and a maintenance positioning component, comprising a rotary coarse positioning component and a length positioning component detachably connected to the rotary coarse positioning component, the bottom of the length positioning component having a locking socket corresponding to the detection traction component; wherein, when the detection traction component detects a distance value exceeding the distance threshold corresponding to the corresponding detection position, the rotary coarse positioning component drives the length positioning component to initially reach one side of the detection traction component, the detection traction component extends towards the locking socket, and after reaching its position, the maintenance positioning component moves the locking socket towards the detection traction component for latching, and then the detection traction component continues to rotate within the locking socket, so that the length positioning component positions the cross-section length corresponding to the distance value being lower than the distance threshold on the tunnel cross-section.

[0006] In one embodiment of the present invention, the bracket assembly includes: a base; an upper bracket located above the base; a horizontal adjustment drive, wherein multiple horizontal adjustment drives are respectively mounted on the base, and the power output end of each horizontal adjustment drive is movably connected to the bottom of the upper bracket; and a guide bracket mounted on the upper bracket, wherein a guide rail is arranged on the upper bracket.

[0007] In one embodiment of the present invention, the detection traction assembly includes: a rotating base located above the support assembly; a lifting drive mounted on the support assembly, the power output end of the lifting drive being connected to the rotating base; a rotating arm assembly rotatably mounted on the rotating base; a lifting assembly elastically connected to the rotating arm assembly, the two sides of the lifting assembly being slidably disposed within guide rails, the top of the lifting assembly corresponding to a locking socket; and a laser rangefinder connected to the lifting assembly, used to detect the distance value corresponding to each detection position of the rotating arm assembly when the rotating arm assembly rotates.

[0008] In one embodiment of the present invention, the lifting assembly includes: a guide platform, with both sides of the guide platform slidably disposed within a guide rail via guide posts, and the guide platform being connected to a laser rangefinder; an insert rod, one end of which is connected to the guide platform, and the other end of which is retractably inserted into a rotating arm assembly; an elastic element, which is sleeved on the insert rod, one end of which is connected to the guide platform, and the other end of which is connected to the rotating arm assembly; a lifting block, which is slidably disposed on the top of the guide platform; and a lifting drive, which is mounted on the guide platform, and the power output end of the lifting drive is connected to the lifting block.

[0009] In one embodiment of the present invention, the detection traction assembly further includes: a laser receiver and a laser emitter; the rotating arm assembly includes: a rotating arm, one end of which is rotatably mounted on a rotating base, and the other end of which is connected to a lifting assembly; and a rotating drive, which is mounted on one side of the rotating base, and the power output end of the rotating drive is connected to the rotating arm; a rotating coarse positioning assembly is mounted on the other side of the rotating base; the laser receiver is mounted on the outside of the rotating drive for receiving a first positioning laser signal; and the laser emitter is connected to the other side of the rotating base and is located outside the rotating coarse positioning assembly for emitting a second positioning laser signal.

[0010] In one embodiment of the present invention, the rotary coarse positioning component includes: a coarse positioning drive, which is installed on one side of the detection traction component; and a coarse positioning bracket, one end of which is connected to the power output end of the coarse positioning drive, and the bottom of which is detachably connected to the length positioning component via a pin.

[0011] In one embodiment of the present invention, the length positioning component includes: a sliding base, which is slidably disposed in a first guide rail on one side of the bracket assembly. The bottom of the sliding base is provided with an insertion hole, in which a pin is inserted. Both ends of the pin pass through a rotating coarse positioning component, so that the rotating coarse positioning component is detachably connected to the sliding base; a positioning socket assembly, which is slidably disposed on the sliding base, with a locking socket located at the bottom of the positioning socket assembly; and a push-in drive, which is mounted on the sliding base and whose power output end is connected to the positioning socket assembly. After the push-in drive pushes the positioning socket assembly and the extended detection traction component to move the latch, the detection traction component continues to rotate within the locking socket, causing the positioning socket assembly to locate the cross-sectional length on the tunnel cross-section when the distance value is lower than a distance threshold.

[0012] In one embodiment of the present invention, the positioning socket assembly includes: a fixed block, one side of which is elastically connected to the power output end of a push-insert drive, and a first notch is provided on one side of the bottom of the fixed block; a movable block, which is slidably disposed on one side of the fixed block, and a second notch corresponding to the first notch is provided on one side of the bottom of the fixed block, wherein the volume of the locking socket formed by the first notch and the second notch is minimized when the fixed block and the movable block are close to each other; and a positioning display component, one end of which passes through the inner side of the fixed block and is connected to the inner side of the movable block; the push-insert drive drives the fixed block to press against one side of the bracket assembly; when the detection traction component continues to rotate in the locking socket, the movable block is driven to rotate by the detection traction component, and the positioning display component is elongated; when the distance value is less than the distance threshold, the movable block is locked to one side of the fixed block, so that the positioning display component can illuminate the corresponding tunnel cross-section with a display laser to locate the cross-section length corresponding to the distance value being less than the distance threshold on the tunnel cross-section.

[0013] In one embodiment of the present invention, the positioning display component includes: a laser strip, one end of which passes through the inner side of the fixed block and is connected to the inner side of the movable block; a storage tray, which is disposed on one side of the fixed block, and the other end of the laser strip is wound around the storage tray; and a storage bracket, which is mounted on the fixed block, and the storage tray is rotatably disposed on the storage bracket, and the storage tray is elastically connected to the storage bracket by a torsion spring.

[0014] In one embodiment of the present invention, the length positioning component further includes a guide component for slidingly connecting and locking the fixed block and the movable block; the guide component includes: a guide frame, which is mounted on the fixed block and has an insertion channel; a guide rod, one end of which is inserted into the insertion channel and the other end of which is connected to the movable block; and a locking drive, which is mounted on the guide frame and has a power output end that extends through the guide frame into the guide channel to lock the position of the guide rod.

[0015] The beneficial effects of this invention are as follows: This invention proposes an integrated equipment for rapid full-section detection and maintenance of tunnel engineering. By adjusting the height of the detection traction component and the maintenance positioning component through a support assembly, a length positioning component is pre-installed on the rotating coarse positioning component. This ensures that when the detection traction component rotates to detect the tunnel cross-section, the path formed by the detection laser emission position of the detection traction component corresponds to the preset shape of the tunnel cross-section. During subsequent detection, the detection traction component rotates along a guide rail to ensure the accuracy of the detection laser emission position. Rotating along a preset trajectory of the preset track cross-section determines the distance between the tunnel cross-section and the laser emission position, and the corresponding detection position. It also ensures the consistency of the distance threshold for each detection position. When the distance value detected by the detection traction component is greater than the distance threshold corresponding to the laser emission position and the corresponding detection position on the tunnel cross-section, it indicates that the tunnel cross-section at that detection position does not require maintenance. Conversely, if the distance value is less than the distance threshold, it indicates a protrusion problem at the corresponding position on the tunnel cross-section, requiring timely repair. Therefore, by further driving the coarse positioning component to rotate, the length positioning component can be initially positioned to one side of the detection traction component. Then, the detection traction component is controlled to extend towards the locking socket. When the extension height of the detection traction component is consistent with the locking socket, the length positioning component will move towards the detection traction component so that the locking socket and the extended detection traction component can be engaged. In order to locate the length of the tunnel cross-section where the distance value is lower than the distance threshold, the detection traction component continues to rotate within the locking socket, so that the length positioning component locates the cross-sectional length corresponding to the distance value being lower than the distance threshold on the tunnel cross-section. This allows the cross-sectional length to be displayed continuously after it is located, making it convenient for construction personnel to complete the repair and maintenance of the protruding part according to the cross-sectional length indication. This enables the subsequent initial support and other procedures to be completed quickly based on the repaired tunnel cross-section. Attached Figure Description

[0025] The following specific examples illustrate the implementation of this invention. Those skilled in the art can easily understand the other advantages and effects of this invention from the content disclosed in this specification. This invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this invention.

It should also be understood that the terminology used in the embodiments of this invention is for describing specific implementation schemes and not for limiting the scope of protection of this invention. Test methods in the following embodiments that do not specify specific conditions are generally performed under conventional conditions or according to the conditions recommended by the respective manufacturers.

[0026] Please see Figures 1 to 8It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed in the invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0027] Please see Figure 1 This invention provides an integrated equipment for rapid full-section detection and maintenance of tunnel engineering, comprising: a support assembly 1, on which a guide rail 10 corresponding to the shape of the tunnel cross-section is provided; a detection traction component 2, mounted on the support assembly 1 and slidably disposed within the guide rail 10, used to rotate and detect the distance value between itself and the tunnel cross-section and the detection position of the detection traction component 2 corresponding to each distance value; and a maintenance positioning component 3, comprising a rotary coarse positioning component 31 and a length positioning component 32 detachably connected to the rotary coarse positioning component 31. The bottom of 32 is provided with a locking socket 33 corresponding to the detection traction component 2; wherein, when the detection traction component 2 detects a distance value that exceeds the distance threshold corresponding to the corresponding detection position, the coarse positioning component 31 is rotated to drive the length positioning component 32 to initially reach one side of the detection traction component 2, and the detection traction component 2 extends to one side of the locking socket 33. After it is in place, the maintenance positioning component 3 moves the locking socket 33 to the detection traction component 2 to insert. Subsequently, the detection traction component 2 continues to rotate in the locking socket 33, so that the length positioning component 32 locates the cross-sectional length corresponding to the distance value being lower than the distance threshold on the tunnel cross-section.

[0028] From the above, it is clear that during the full-section monitoring and maintenance after tunnel blasting, the height of the detection traction component 2 and the maintenance positioning component 3 can be adjusted using the support assembly 1. A length positioning component 32 is pre-installed on the rotating coarse positioning component 31, ensuring that when the detection traction component 2 rotates to detect the tunnel cross-section, the path formed by the detection laser emission position of the detection traction component 2 corresponds to the preset tunnel cross-section shape. During subsequent detection, the detection traction component 2 can rotate along the guide rail 10 to ensure the accuracy of the detection laser emission position. Rotating according to the preset trajectory of the preset track cross-section determines the distance between the tunnel cross-section and the laser emission position, and the corresponding detection position, ensuring consistency of the distance threshold for each detection position. The tunnel cross-section typically includes an arc-shaped cross-section and vertically arranged sections at both ends of the arc-shaped cross-section. Therefore, the detection position can include the detection height after the height adjustment of the detection traction component 2 and the detection angle corresponding to each distance value after the rotation of the detection traction component 2. When the distance value detected by the traction component 2 is greater than the distance threshold between the laser emission position and the corresponding detection position on the tunnel cross-section, it indicates that the tunnel cross-section corresponding to that detection position does not need maintenance or repair. If the distance value is less than the distance threshold, it indicates that there is a protrusion problem at the corresponding position of the tunnel cross-section, and timely repair is required. Therefore, by further driving the coarse positioning component 31 to rotate, the length positioning component 32 can be initially brought to one side of the detection traction component 2. Then, the detection traction component 2 is controlled to extend towards the locking socket 33. When the extension height of the detection traction component 2 is consistent with the locking socket 33, the length positioning component 32 will move towards the detection traction component 2 so that the locking socket 33 and the extended detection traction component 2 can be engaged. In order to locate the length of the tunnel cross-section where the distance value is lower than the distance threshold, the detection traction component 2 continues to rotate in the locking socket 33, so that the length positioning component 32 locates the cross-sectional length corresponding to the distance value being lower than the distance threshold on the tunnel cross-section. This allows the cross-sectional length to be displayed after it is located, so that construction personnel can complete the repair and maintenance of the protruding part according to the cross-sectional length indication, and thus quickly complete the subsequent initial support based on the repaired tunnel cross-section.

[0029] like Figure 1 and Figure 2 As shown, the bracket assembly 1 includes: a base 11; an upper bracket 12 located above the base 11; a horizontal adjustment drive 13, with multiple horizontal adjustment drives 13 respectively mounted on the base 11, and the power output end of each horizontal adjustment drive 13 being movably connected to the bottom of the upper bracket 12; and a guide bracket 14 mounted on the upper bracket 12, with a guide rail 10 arranged on the upper bracket 12.

[0030] In the support assembly 1, the horizontal adjustment drive 13 can be a push rod motor, or other linear drive mechanisms. During the installation of the support assembly 1, the base 11 can be installed on a mounting frame such as a tripod to achieve fixed-point tunnel section detection at various predetermined locations on the tunnel section. Alternatively, the base 11 can be installed on a mobile vehicle to achieve mobile tunnel section detection. When adjusting the height of the detection traction component 2, the support assembly 1 can adjust the level of the upper support 12 by extending and retracting each horizontal adjustment drive 13 along the height direction, thereby achieving the height position of the detection traction component 2 and the positioning component 3 on one side. In addition, each horizontal adjustment drive 13 has a rotating ball connected to its power output end, and by clamping the rotating ball in the bottom ball seat of the upper support 12, the angle between the horizontal adjustment drive 13 and the upper support 12 is adaptively adjusted when the horizontal adjustment drive 13 is adjusted in height.

[0031] like Figures 2 to 4 As shown, the detection traction assembly 2 includes: a rotating base 21, located above the support assembly 1; a lifting drive 22, mounted on the support assembly 1, with its power output end connected to the rotating base 21; a rotating arm assembly 23, rotatably mounted on the rotating base 21; a lifting assembly 24, elastically connected to the rotating arm assembly 23, with both sides of the lifting assembly 24 slidably disposed within the guide rail 10, and its top corresponding to the locking socket 33; and a laser rangefinder 25, connected to the lifting assembly 24, used to detect the distance value corresponding to each detection position when the rotating arm assembly 23 rotates.

[0032] When the detection traction component 2 performs rotational detection, the lifting drive 22 mounted on the rotating base 21 drives the rotating arm component 23 to rotate, thereby causing the lifting component 24 at the top of the rotating arm component 23 and the laser rangefinder 25 to rotate together. When the distance value detected by the laser rangefinder 25 is less than the distance threshold, the lifting component 24 is further controlled to extend upward to the corresponding height of the locking socket 33. Then, the length positioning component 32 moves toward the lifting component 24, so that the locking socket 33 is inserted into the guide rail 10. This allows the length positioning component 32 to locate and record the cross-sectional length corresponding to the distance value being lower than the distance threshold as the lifting component 24 continues to rotate. The lifting drive 22 can be a push rod motor, or other linear drive mechanisms.

[0033] like Figures 3 to 5As shown, the lifting assembly 24 includes: a guide platform 241, with both sides of the guide platform 241 slidably disposed within the guide rail 10 via guide posts 2411, and the guide platform 241 connected to the laser rangefinder 25; an insert rod 242, one end of which is connected to the guide platform 241, and the other end of which is retractably inserted into the rotating arm assembly 23; an elastic element 243, which is sleeved on the insert rod 242, one end of which is connected to the guide platform 241, and the other end of which is connected to the rotating arm assembly 23; a lifting block 244, which is slidably disposed on the top of the guide platform 241; and a lifting drive 245, which is mounted on the guide platform 241, and the power output end of the lifting drive 245 is connected to the lifting block 244.

[0034] To ensure that the distance threshold corresponding to each detection position remains unchanged when the laser rangefinder 25 rotates, thus improving detection convenience, a guide platform 241 can be inserted into the guide rail 10 using guide posts 2411. During the rotation of the rotating arm assembly 23, the guide platform 241 can be moved and guided by the guide rail 10, ensuring that the movement trajectory of the guide platform 241 linearly corresponds to the guide bracket 14 and the guide rail 10 on the guide bracket 14. That is, when the rotating arm assembly 23 moves up and down or rotates, the distance threshold between the laser emission position of the laser rangefinder 25 and the tunnel cross-section remains constant, improving the efficiency of comparing the distance value with the distance threshold, reducing the need for distance threshold adjustment calculations, and increasing computational efficiency. When the detected distance value is less than the distance threshold, the lifting drive 245 can be controlled to drive the lifting block 244 upwards along the guide platform 241 to reach the corresponding height on the side of the locking socket 33, so that the locking socket 33 at the bottom of the length positioning component 32 can position and lock the lifting block 244. The elastic element 243 can be a spring, or other elastic components. The lifting drive 245 can be a push rod motor, or other linear drive mechanisms.

[0035] like Figures 2 to 4 As shown, the detection traction assembly 2 further includes: a laser receiver 26 and a laser emitter 27; the rotating arm assembly 23 includes: a rotating arm 231, one end of which is rotatably mounted on the rotating base 21, and the other end of which is connected to the lifting assembly 24; and a rotating drive 232, which is mounted on one side of the rotating base 21, and the power output end of the rotating drive 232 is connected to the rotating arm 231; a rotating coarse positioning assembly 31 is mounted on the other side of the rotating base 21; the laser receiver 26 is mounted on the outside of the rotating drive 232 for receiving a first positioning laser signal; and the laser emitter 27 is connected to the other side of the rotating base 21 and is located on the outside of the rotating coarse positioning assembly 31 for emitting a second positioning laser signal.

[0036] To better indicate the protruding positions of multiple integrated rapid detection and maintenance equipment along the tunnel length, the laser receiver 26 can receive the first positioning laser signal emitted by the previous group of integrated rapid detection and maintenance equipment. This first positioning laser signal is then used to adjust the support assembly 1, ensuring that the detection height of the detection traction component 2 meets the shape requirements of the tunnel cross-section. Simultaneously, after the detection traction component 2 has been adjusted and the protruding positions indicated, it returns to its initial position and emits a second positioning laser signal via the laser emitter 27 on its other side to provide laser positioning indication for the other integrated rapid detection and maintenance equipment. Furthermore, when the rotating arm assembly 23 drives the lifting assembly 24 and the laser rangefinder 25 to rotate, the rotating arm 231 is driven to rotate by the rotation drive 232 on the rotating base 21. This causes the guide platform 241, connected by the insert rod 242 and the elastic element 243, to move along the guide direction of the guide rail 10. This adjusts the detection height and detection angle of the laser rangefinder 25, which is connected to the guide platform 241, to illuminate the tunnel cross-section, thereby obtaining the corresponding distance value. This value is then compared with a corresponding distance threshold to locate the protruding position of the cross-section. The rotation drive 232 can be a servo motor, or other rotation drive mechanisms.

[0037] like Figure 2 and Figure 3 As shown, the rotary coarse positioning assembly 31 includes: a coarse positioning drive 311, which is installed on one side of the detection traction assembly 2; and a coarse positioning bracket 312, one end of which is connected to the power output end of the coarse positioning drive 311, and the bottom of the coarse positioning bracket 312 is detachably connected to the length positioning assembly 32 via a pin 3121.

[0038] When the detected distance value is less than the distance threshold, the coarse positioning component 31 rotates, driving the length positioning component 32 to rotate, reaching the position of the lifting block 244 of the detection traction component 2, to complete the locking with the lifting block 244. Specifically, the coarse positioning drive 311 installed on one side of the rotating seat 21 of the detection traction component 2 can be driven to rotate, thereby driving the coarse positioning bracket 312 and the length positioning component 32 installed on the coarse positioning bracket 312 to rotate, initially reaching one side of the lifting position of the lifting block 244 of the detection traction component 2. Then, the length positioning component 32 further moves towards the lifting block 244, realizing the locking between the locking socket 33 and the lifting block 244. The coarse positioning drive 311 can be a push rod motor, or other linear drive mechanisms.

[0039] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the length positioning component 32 includes: a sliding base 321, which is slidably disposed within a first guide rail 15 on one side of the bracket assembly 1. The bottom of the sliding base 321 is provided with an insertion hole, and a pin 3121 is inserted into the insertion hole. Both ends of the pin 3121 pass through the rotating coarse positioning component 31, so that the rotating coarse positioning component 31 and the sliding base 321 are detachably connected; a positioning socket component 322, which is slidably disposed on the sliding base 321, and a locking socket 33 is disposed at the bottom of the positioning socket component 322; and a push-in drive 323, which is mounted on the sliding base 321 and whose power output end is connected to the positioning socket component 322. Wherein, after the push-in drive 323 pushes the positioning socket component 322 and the extended detection traction component 2 to move the buckle, the detection traction component 2 continues to rotate within the locking socket 33, so that the positioning socket component 322 positions the cross-sectional length corresponding to the distance value being lower than the distance threshold on the tunnel cross-section.

[0040] After the rotary coarse positioning component 31 drives the length positioning component 32 to the extended side of the detection traction component 2, the push-insertion drive 323 pushes the positioning socket component 322 on the sliding base 321 towards the lifting block 244 of the detection traction component 2, so that the lifting block 244 is completely inserted into the locking socket 33. After insertion, the detection traction component 2 continues to move to detect the distance value of the corresponding detection position, so that the positioning socket component 322 can locate the cross-sectional length corresponding to the distance value being lower than the distance threshold on the tunnel cross-section. The push-insertion drive 323 can be a servo motor, or other rotary drive mechanisms. After locating a cross-sectional length, the pin 3121 can be removed and rotated to the area between the detection traction component 2 and the previous length positioning component 32, and a new length positioning component 32 can be replaced to detect and locate protrusions at other positions. The push-insertion drive 323 can be a push rod motor, or other linear drive mechanisms.

[0041] like Figures 5 to 7As shown, the positioning socket assembly 322 includes: a fixed block 3221, one side of which is elastically connected to the power output end of the push-insert drive 323, and a first notch 32211 is provided on one side of the bottom of the fixed block 3221; a movable block 3222, which is slidably disposed on one side of the fixed block 3221, and a second notch 32221 corresponding to the first notch 32211 is provided on one side of the bottom of the fixed block 3221, wherein the locking socket 33 formed by the first notch 32211 and the second notch 32221 has the smallest volume when the fixed block 3221 and the movable block 3222 are close to each other; and a positioning display assembly 3223, which positions... One end of the display component 3223 passes through the inner side of the fixed block 3221 and connects to the inner side of the moving block 3222; the push-insert drive 323 drives the fixed block 3221 to press against one side of the bracket assembly 1. When the detection traction component 2 continues to rotate in the locking socket 33, the moving block 3222 is driven to rotate by the detection traction component 2, and the positioning display component 3223 is stretched. When the distance value is less than the distance threshold, the moving block 3222 is locked to one side of the fixed block 3221, so that the positioning display component 3223 can illuminate the corresponding tunnel section with the display laser to locate the section length corresponding to the distance value being less than the distance threshold on the tunnel section.

[0042] When the positioning socket assembly 322 determines the cross-sectional length corresponding to a distance value lower than a distance threshold, the fixed block 3221 can be pressed against one side of the bracket assembly 1 after the detection traction assembly 2 engages with the locking socket 33. Then, during the continued detection process, when the distance value is lower than the distance threshold, the detection traction assembly 2 will push the moving block 3222 to continue moving through the second notch 32221. This allows the positioning display assembly 3223 to emit a display laser onto the corresponding tunnel cross-section when the moving block 3222 leaves the fixed block 3221, based on the arc length or straight line length of the departure. This allows the cross-sectional length corresponding to a distance value lower than the distance threshold to be located on the tunnel cross-section. For straight lengths, the positioning display component 3223 can be arranged when the guide rail 10 is a straight rail. When the positioning display component 3223 is extended, it exhibits a straight state. For curved lengths, the positioning display component 3223 can be arranged when the guide rail 10 is a curved rail. When the positioning display component 3223 is extended, it exhibits a curved state.

[0043] In addition, a guide opening is provided on one side of the fixed block 3221, and a slider 32212 is slidably arranged in the guide opening. The two sides of the slider 32212 are respectively connected to the inner wall of the guide opening through a spring 32213. The slider 32212 is also connected to the power output end of the push-insert drive 323. Thus, when the fixed block 3221 and the moving block 3222 are locked, the initial position when the laser rangefinder 25 detects a distance value less than the distance threshold is located by using the mutual interlocking of the detection traction component 2 and the locking socket 33.

[0044] like Figure 7 and Figure 8 As shown, the positioning display component 3223 includes: a laser strip 32231, one end of which passes through the inner side of the fixed block 3221 and connects to the inner side of the moving block 3222; a storage tray 32232, which is disposed on one side of the fixed block 3221, and the other end of the laser strip 32231 is wrapped around the storage tray 32232; and a storage bracket 32233, which is mounted on the fixed block 3221, and the storage tray 32232 is rotatably disposed on the storage bracket 32233, and the storage tray 32232 is elastically connected to the storage bracket 32233 via a torsion spring 32234.

[0045] When the moving block 3222 moves under the push of the detection traction component 2, the moving block 3222 will pull the laser strip 32231 connected to it to stretch between the moving block 3222 and the fixed block 3221. The length of the stretch represents the cross-sectional length when the distance value is less than the distance threshold. At the same time, when the laser strip 32231 is stretched, the receiving disk 32232 rotates to release the laser strip 32231. Meanwhile, the torsion spring 32234 stores energy due to the rotation of the receiving disk 32232. If the moving block 3222 is released and the moving block 3222 is not locked, the elastic potential energy of the torsion spring 32234 will also pull the moving block 3222 back to the initial position on the side of the fixed block 3221 through the laser strip 32231.

[0046] Please see Figure 8For the laser strip 32231 when the guide track 10 is an arc track, it can include multiple trapezoidal laser light modules 322311. The laser light modules 322311 are softly connected, for example, by using soft fire-retardant plastic or other materials for the soft connection between the laser light modules 322311. A notch 322312 is formed between two adjacent laser light modules 322311, and magnets 322313 are attached to both sides of the laser light module 322311. The corresponding ends of the magnets 322313 on two adjacent laser light modules 322311 are opposite magnetic poles, so that when the laser strip 32231 is stretched into an arc shape, the two adjacent laser light modules 322311 are attracted to each other and stuck together by the magnets 322313, so that the notch 322312 is closed, thereby combining the laser light modules 322311 into an arc shape.

[0047] For the laser strip 32231 when the guide rail 10 is a straight track, it can be a complete soft straight laser strip.

[0048] like Figure 7 As shown, the length positioning component 32 further includes a guide component 324 for slidingly connecting and locking the fixed block 3221 and the movable block 3222; the guide component 324 includes: a guide frame 3241, which is mounted on the fixed block 3221 and has an insertion channel; a guide rod 3242, one end of which is inserted into the insertion channel and the other end of which is connected to the movable block 3222; and a locking drive 3243, which is mounted on the guide frame 3241 and has its power output end extending through the guide frame 3241 into the guide channel 32411 to lock the position of the guide rod 3242.

[0049] When the moving block 3222 moves, it can be guided by the guide component 324 to ensure that the moving block 3222 can slide back and forth along the corresponding straight or curved track. Furthermore, when it reaches its position, the locking drive 3243 can be controlled to extend its power output end and press against the guide rod 3242, thereby stopping the guide rod 3242 within the insertion channel and completing the position locking. Subsequently, the detection traction component 2 leaves the second notch 32221 and continues to complete the distance value detection and inspection work at other detection positions.

[0050] Specifically, when the detection traction component 2 is traveling on a straight track, both the insertion channel and the guide rod 3242 are straight; when the detection traction component 2 is traveling on an arc track, both the insertion channel and the guide rod 3242 are arc-shaped.

[0051] In summary, the present invention discloses an integrated equipment for rapid full-section detection and maintenance of tunnel engineering. By adjusting the height of the detection traction component 2 and the maintenance positioning component 3 through the support assembly 1, a length positioning component 32 is pre-installed on the rotating coarse positioning component 31. This ensures that when the detection traction component 2 rotates to detect the tunnel cross-section, the path formed by the detection laser emission position of the detection traction component 2 corresponds to the preset shape of the tunnel cross-section. During subsequent detection, the detection traction component 2 can rotate along the guide rail 10 to ensure the accuracy of the detection laser emission position. Rotating along the preset trajectory of the preset track cross-section determines the distance between the tunnel cross-section and the laser emission position, and the corresponding detection position, ensuring consistency of the distance threshold for each detection position. When the distance value detected by the detection traction component 2 is greater than the distance threshold corresponding to the laser emission position and the corresponding detection position on the tunnel cross-section, it indicates that the tunnel cross-section at that detection position does not require maintenance. If the distance value is less than the distance threshold, it indicates that there is a protrusion problem at the corresponding position of the tunnel cross-section, requiring timely repair. Therefore, by further driving the coarse positioning component 31 to rotate, the length positioning component 32 can initially reach one side of the detection traction component 2. Then, the detection traction component 2 is controlled to extend towards the locking socket 33. When the extension height of the detection traction component 2 is consistent with the locking socket 33, the length positioning component 32 will move towards the detection traction component 2, so that the locking socket 33 and the extended detection traction component 2 can be engaged. In order to locate the length on the tunnel cross-section where the distance value is lower than the distance threshold, the detection traction component 2 continues to rotate within the locking socket 33, so that the length positioning component 32 locates the cross-sectional length corresponding to the distance value being lower than the distance threshold on the tunnel cross-section. This allows the cross-sectional length to be displayed continuously after it is located, facilitating construction personnel to complete the repair and maintenance of the protruding part according to the cross-sectional length indication, thereby quickly completing subsequent initial support and other processes based on the repaired tunnel cross-section. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0052] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
