Description

Technical Field

[0001] This invention belongs to the field of highway tunnel engineering technology, and in particular relates to a multifunctional lining quality testing device and method for highway tunnels during construction and maintenance. Background Technology

[0002] The safety and durability of tunnels are crucial for ensuring smooth traffic flow and driving safety, and the quality of the lining structure directly affects its efficiency and lifespan. Therefore, implementing effective lining quality inspection is particularly important during the construction and maintenance of tunnels.

[0003] Currently, the efficiency of tunnel lining quality inspection is not high, often requiring manual inspection, which is time-consuming and labor-intensive; in addition, the inspection range is limited, and most inspection routes need to be repeated multiple times to collect data from multiple survey lines, resulting in a low degree of automation; furthermore, existing mounted radar inspection devices either focus on the tunnel construction period or the operation period, and there are few inspection devices that can adapt to both stages simultaneously. Summary of the Invention

[0004] The present invention addresses the problems existing in the prior art. Specifically, the technical problem to be solved by the present invention is to provide a multifunctional lining quality testing device and method for highway tunnels during the construction and maintenance period. The device and method are reasonably designed and can comprehensively, accurately and quickly test the lining quality of tunnels during the construction and maintenance period without affecting normal construction and operation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a multifunctional lining quality inspection device for highway tunnel construction and maintenance, comprising a support unit, a traveling unit, and a lining inspection unit. The support unit includes a pair of main support arms distributed on the left and right, and a main connecting arm disposed between the pair of main support arms. The traveling unit is disposed at the lower end of the pair of main support arms and drives the pair of main support arms to travel. The lining inspection unit includes multiple radar detection components distributed circumferentially along the tunnel cross section, and the multiple radar detection components are installed on the pair of main support arms and the main connecting arm.

[0006] Furthermore, each of the two main support arms is provided with a vertical sliding track on opposite sides, and two radar detection components are slidably connected on the vertical sliding track; a radar detection component is provided at the top and upper left and right ends of the main connecting arm.

[0007] Furthermore, the radar detection assembly includes a telescopic arm, the telescopic end of which is rotatably connected to a rotatable frame, on which a radar probe is mounted.

[0008] Furthermore, the rotatable frame has four cross-shaped tracks on the end face away from the telescopic arm; each radar detection component has four radar probes, the four radar probes correspond to the positions of the four cross-shaped tracks, and each radar probe is mounted on a radar rod, which is rotatably mounted on the corresponding cross-shaped tracks by a rolling ball.

[0009] Furthermore, the radar probe is connected to the radar rod via a flexible spring.

[0010] Furthermore, the radar detection component also includes a high-definition camera, an illumination component, an infrared distance sensor, and a data transmission module, all of which are connected to the terminal platform. The high-definition camera, illumination component, infrared distance sensor, and data transmission module are all mounted on a rotatable frame. The high-definition camera acquires images of the lining surface, and the radar data detected by the radar probe and the image information acquired by the high-definition camera are transmitted to the terminal platform through the data transmission module.

[0011] Furthermore, the rotatable frame of the radar detection component is also equipped with a dust removal spray nozzle.

[0012] Furthermore, a vertical telescopic arm is installed at the top of each main support arm, and a horizontal telescopic arm is installed at the lower left and right ends of the main connecting arm. The horizontal telescopic arms at the lower left and right ends of the main connecting arm are connected to the vertical telescopic arms at the top of a pair of main support arms. The horizontal telescopic arms at the lower left and right ends of the main connecting arm drive a pair of main support arms to move in opposite directions or in opposite directions.

[0013] Furthermore, the traveling unit includes a pair of left and right distributed bases, each base having a traveling track installed at both ends of its left and right sides. A horizontal roller that can extend and retract vertically is installed in the middle of the bottom surface of the base, and the horizontal roller can move left and right. A pair of main support arms are positioned corresponding to the pair of bases, and the main support arms are vertically installed on the upper part of the corresponding bases.

[0014] Another technical solution adopted in this invention is: a multi-functional lining quality inspection method for highway tunnels during construction and maintenance, comprising the following steps:

[0015] Step a: Start the device at the starting point of the required detection mileage, extend the lateral roller downwards until the track leaves the ground, then extend the lateral telescopic arm in the left and right directions, and drive a pair of main support arms to move in opposite directions in the left and right directions so that the space between the pair of main support arms does not affect the normal passage of vehicles.

[0016] Step b: Perform attitude adjustment. The telescopic arm of each radar detection component automatically extends and retracts, and the rotatable frame on the telescopic arm automatically rotates, moving the telescopic arms of the four radar detection components at the bottom of the entire device to the designated position, and finally bringing the radar probe into contact with the tunnel wall.

[0017] Step c: The traveling unit moves longitudinally in the tunnel to perform quality inspection and image acquisition on the tunnel lining, and transmits the acquired radar data and high-definition images to the terminal platform for display.

[0018] Step d: The terminal platform analyzes the collected data and images. If any defects or problems are found, they are displayed and alerted on the platform in real time.

[0019] Compared with the prior art, the present invention has the following advantages: The present invention is reasonably designed and can realize the detection of the internal quality of the tunnel lining during the construction and operation period, and is applicable to a variety of complex engineering environments; it is highly operable and can adjust its posture and travel speed based on the tunnel outline and environment to ensure the continuity and accuracy of the lining quality detection.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0031] like Figures 1-6 As shown, this invention discloses a multifunctional lining quality detection device for highway tunnels during the construction and maintenance period. Its purpose is to comprehensively, accurately, and rapidly detect the lining quality during the tunnel construction and maintenance period without affecting normal construction and operation, thereby improving the intelligence level of lining quality detection and diagnosis. Specifically, it includes a support unit, a traveling unit, and a lining detection unit. The support unit includes a pair of left and right main support arms 8 and a main connecting arm 9 positioned between the pair of main support arms 8. The traveling unit is located at the lower end of the pair of main support arms 8 and drives the pair of main support arms 8 to travel, controlling the movement of the entire device within the tunnel. The lining detection unit includes multiple radar detection components 1 circumferentially distributed along the tunnel cross-section. These radar detection components 1 are installed on the pair of main support arms 8 and the main connecting arm 9, and are used to fit against the tunnel inner wall to achieve lining quality detection.

[0032] In this embodiment, there are seven radar detection components 1. Vertical sliding tracks 7 are provided on opposite sides of each pair of main support arms 8; that is, a vertical sliding track 7 is provided on the left side of the left main support arm 8, and a vertical sliding track 7 is also provided on the right side of the right main support arm 8. Two radar detection components 1 are slidably connected to the vertical sliding track 7 on each main support arm 8. The two radar detection components 1 on the vertical sliding track 7 can move up and down to adjust their positions. One radar detection component 1 is provided at the top and at each of the upper left and right ends of the main connecting arm 9.

[0033] In this embodiment, the seven radar detection components have the same structure. Each radar detection component 1 includes a telescopic arm 4. The telescopic end of the telescopic arm 4 is rotatably connected to a rotatable frame 3 via a cylindrical connector 13. The rotatable frame 3 can rotate 180 degrees around the cylindrical connector 13. A radar probe 15 is mounted on the rotatable frame 3. Furthermore, in the two radar detection components 1 on the vertical sliding track 7, their telescopic arms 4 are arranged horizontally (i.e., they extend and retract horizontally); in the radar detection component 1 at the top of the main connecting arm 9, its telescopic arm 4 is arranged vertically (i.e., it extends and retracts vertically); in the radar detection components 1 at the upper left and right ends of the main connecting arm 9, their telescopic arms 4 are arranged horizontally.

[0034] In this embodiment, a vertical telescopic arm 6 is installed at the top of each main support arm 8, and a horizontal telescopic arm 5 is installed at the lower left and right ends of the main connecting arm 9. The horizontal telescopic arms 5 at the lower left and right ends of the main connecting arm 9 are connected to the vertical telescopic arms 6 at the top of the pair of main support arms 8. When the vertical telescopic arms 6 extend or retract, the height of the main connecting arm 9 can be adjusted. The horizontal telescopic arms 5 at the lower left and right ends of the main connecting arm 9 drive the pair of main support arms 8 to move in opposite directions or in opposite directions, thereby adjusting the distance between the pair of main support arms 8 to ensure that normal vehicle traffic is not affected.

[0035] In this embodiment, the vertical telescopic arm 6, the horizontal telescopic arm 5, and the telescopic arms 4 integrated into each radar detection component 1 are combined to allow for telescopic adjustment based on changes in the tunnel contour during the entire device's movement (i.e., attitude adjustment of the entire device), ensuring that the radar probe remains in contact with the tunnel wall. Furthermore, it should be noted that both the vertical and horizontal telescopic arms are electrically telescopic, with their motors, guide rails, and other components housed internally. Their specific structures and working principles will not be elaborated upon further here. The telescopic arms of the radar detection components are telescopically operated via a hydraulic drive system, including a hydraulic pump, hydraulic cylinders, and control valves. The hydraulic pump provides power to the hydraulic cylinders, and the control valves control the telescopic movements of the hydraulic cylinders, thereby achieving the telescopic arm's extension and retraction. The hydraulic cylinders are connected to the telescopic structure inside the telescopic arm, converting hydraulic energy into mechanical energy to drive the telescopic movement. Meanwhile, the rotatable frame rotates through a transmission device consisting of a motor, a reducer, and a coupling. The motor output torque is reduced and increased by the reducer, and then transmitted to the rotatable frame through the coupling. The motor is connected to the control system and can achieve forward, reverse, and precise angular rotation according to control commands. Further details will not be repeated here.

[0036] In this embodiment, the rotatable frame 3 has four rectangularly distributed cross-shaped tracks 14 on its end face away from the telescopic arm 4. Each radar detection component 1 has four radar probes 15, which correspond to the positions of the four cross-shaped tracks 14. Each radar probe 15 is mounted on a radar rod 20. The radar rod 20 is rotatably mounted on the center of the corresponding cross-shaped track 14 via a rolling ball 22. The radar rod 20 can tilt along the space defined by the cross-shaped track, thereby causing the radar probe to tilt and move. Furthermore, one radar probe and one cross-shaped track are arranged at each of the four directions: 45°, 135°, 225°, and 315°. It should be further noted that the radar probe includes an antenna probe and a main unit. The probe is located at the top, and the main unit is installed on the outside of the telescopic arm. The collected data is wirelessly transmitted to the terminal through a data transmission module. The radar mast is rotatably connected to the cross-shaped track via a rolling ball. The radar mast is connected to the hydraulic cylinder via a linkage mechanism. The hydraulic cylinder serves as the power source. When it is necessary to tilt the radar probe, the hydraulic cylinder pushes the linkage mechanism, which is connected to the radar mast, causing the radar mast to tilt on the cross-shaped track.

[0037] In this embodiment, since the contour size of the same tunnel along the direction of travel is not completely consistent, in order to ensure that the radar can always be in contact with the inner wall of the tunnel during the detection process, the radar probe 15 and the radar rod 20 are connected by a flexible spring 21. The flexible spring 21 ensures flexible contact between the radar probe and the inner wall of the tunnel, preventing the contact from becoming too tight due to the shrinking of the tunnel contour. The stability of the contact state between the radar probe 15 and the inner wall of the tunnel is ensured by the compression of the spring and the automatic retraction of the telescopic arm 4.

[0038] In this embodiment, the radar detection component 1 also includes a high-definition camera 16, an illumination component 17, an infrared distance sensor 18, and a data transmission module 19, all of which are connected to the terminal platform. The high-definition camera 16, the illumination component 17, the infrared distance sensor 18, and the data transmission module 19 are all mounted on the circular top of the rotatable frame 3 and controlled by the terminal platform. The high-definition camera 16 collects images of the lining surface, and the radar data detected by the radar probe 15 and the image information collected by the high-definition camera 16 are transmitted to the terminal platform through the data transmission module 19.

[0039] In this embodiment, the distance between the infrared distance sensor 18 and the top of the radar probe 15 is preset in the terminal platform. H The distance between the infrared distance sensor 18 and the tunnel wall is obtained. m This allows for the automatic determination of the fit between the radar probe and the tunnel wall. a : a = m - H .whena When =0, it proves that the radar probe 15 is tightly fitted to the tunnel wall; when a When the value is >0, it indicates that there is a gap between the radar probe and the tunnel wall, which needs to be adjusted. Based on the actual engineering conditions on site, lighting components are used to enhance the image acquisition quality.

[0040] In this embodiment, to enhance image acquisition quality, a dust removal spray nozzle 2 is also provided on the rotatable frame 3 of the radar detection component 1. The dust removal spray nozzle 2 is used to spray water mist to remove dust. Sometimes there is excessive dust or low visibility in the tunnel, which affects the image acquisition quality. Keeping the dust removal spray nozzle 2 and the lighting component 17 constantly on enhances image clarity.

[0041] In this embodiment, the traveling unit includes a pair of left and right distributed bases 10. Each base 10 has a traveling track 11 installed at both its left and right ends, enabling movement via the traveling track 11. A horizontal roller 12, which can extend and retract vertically, is installed in the center of the bottom surface of each base 10 and can move left and right. A pair of main support arms 8 correspond to the positions of the bases 10, and are vertically installed on the upper part of the corresponding bases 10. During operation: the device is activated at the starting point of the required mileage, extending the horizontal roller 12 downwards until the traveling track 11 leaves the ground. Then, the horizontal telescopic arm 5 extends in the left and right directions, driving the pair of main support arms 8 to move in opposite directions. The horizontal roller 12 supports the movement, ensuring that the space between the pair of main support arms 8 does not obstruct normal vehicle passage.

[0042] In this embodiment, the terminal platform integrates the control and quality analysis unit into a visual operation platform. This platform controls various functions, including movement, telescopic boom extension / retraction, rotatable frame rotation, radar mast tilting, dust removal, lighting switching, and high-definition camera acquisition frequency. Device position, movement speed, current status, and detection results are all directly displayed on this platform. Data obtained from detection and photography can be processed and analyzed through this platform. Furthermore, the terminal platform incorporates relevant lining support specifications, enabling analysis and evaluation of lining quality based on detection results. It also allows for real-time annotation of apparent damage based on image information, automatic statistical analysis of defects, and timely early warning alerts.

[0043] In this embodiment, the track 11 has three travel modes: preset travel distance and speed mode, constant speed cruise mode, and manual control mode. The track can switch between these three modes via a terminal platform. In the preset travel distance and speed mode, the mileage to be detected and the travel speed are pre-set, and the device operates according to the preset parameters. In the constant speed cruise mode, the travel speed is set and can be changed at any time. In the manual control mode, the device is manually operated.

[0044] In this embodiment, the telescopic arm 4 and the rotating frame 3 are operated in two modes: automatic and manual, which can be switched via a terminal platform. In automatic mode, the telescopic arm and rotating frame automatically adjust, stopping automatically when the radar and tunnel wall are precisely aligned, using an infrared distance sensor. For fine-tuning or adjustment of the detection area, manual mode can be used.

[0045] In this embodiment, the working principle is as follows:

[0046] In use, first move the device to the designated location and start it at the starting point of the required detection mileage. Using the terminal platform, extend the retractable lateral roller 12 downwards to contact the ground until the track 11 leaves the ground. The lateral telescopic arm 5 extends left and right, and the lateral roller 12 moves left and right, ensuring that the space between the two main support arms 8 does not obstruct other construction work or vehicle passage. The telescopic arms of the four radar detection components at the bottom of the entire device extend and move up and down via the vertical sliding rail 7 until the radar probe 15 reaches the designated detection position. The rotatable frame 3 and radar rod 20 control the radar probe 15 to fit precisely against the tunnel wall. The telescopic arm 4 of the radar detection component 1 at the three locations also achieves a tight fit between the radar probe 15 and the tunnel wall through telescopic adjustment and angle rotation; then the transverse roller 12 is retracted upwards until the traveling track 11 is completely placed on the ground; the travel control function in the terminal platform is activated, and the entire device moves along the tunnel direction, collecting internal quality data of the tunnel lining through the radar probe 15, keeping the lighting component 17 and the infrared distance sensor 18 on, supplemented by dust removal spray nozzle 2, and using a high-definition camera 16 to collect images of the lining surface; the radar data and image information are transmitted to the terminal platform for display and analysis through the data transmission module 19.

[0047] This detection device can inspect the lining quality of the initial support and secondary lining during tunnel construction, and also acquire information on the internal lining quality and apparent damage of the tunnel during operation. During the inspection process, the extension and retraction states of the lateral telescopic arm 5 and the vertical telescopic arm 6 remain unchanged. The telescopic arm 4, the rotatable frame 3, and the radar rod 20 of the radar detection component continuously adjust their posture according to the tunnel contour, ensuring good contact between the radar and the tunnel wall, and allowing normal passage of other vehicles in the space formed between the two main support arms 8. The detection data and acquired images can be transmitted to the terminal platform in real time through the data transmission module, ensuring the immediacy of the information. Furthermore, any problems detected can be promptly identified and resolved.

[0048] In this embodiment, the method for quality inspection of multifunctional lining during the construction and maintenance period of highway tunnels includes the following steps:

[0049] Step a: Before use, move the device to the designated location and start the device at the starting point of the required detection mileage;

[0050] Step b: Extend the lateral roller 12 downwards until the traveling track 11 leaves the ground. Then, extend the lateral telescopic arm 5 in the left and right directions. The lateral telescopic arm 5 drives a pair of main support arms 8 to move in opposite directions in the left and right directions, so that the space between the pair of main support arms 8 does not affect other construction operations and normal vehicle passage.

[0051] Step c: Adjust the attitude. The telescopic arms 4 of the four radar detection components 1 at the bottom of the device extend, and at the same time, the two radar detection components 1 located on the same side move up and down through the vertical sliding rail 7, so that the telescopic arms 4 of the four radar detection components 1 at the bottom of the device move to the designated position until the radar probe 15 of the radar detection component 1 is just in contact with the inner wall of the tunnel. Similarly, the three radar detection components 1 at the top of the device are adjusted by extending and retracting the telescopic arms 4 and rotating the angle of the rotatable frame 3 to achieve a tight fit between the radar probe 15 and the inner wall of the tunnel. Finally, the transverse roller 12 is retracted upward until the traveling track 11 is completely placed on the ground.

[0052] Step d: The traveling unit is started, and the whole device moves along the tunnel direction. The radar probe 15 collects the internal quality data of the tunnel lining. The lighting component 17 and the infrared distance sensor 18 are kept on. The dust removal spray nozzle 2 is used to collect the appearance image of the lining using the high-definition camera 16. The acquired radar data and high-definition images are transmitted to the terminal platform and displayed.

[0053] Step e: The terminal platform analyzes the collected data and images. If any defects or problems are found, they are displayed and alerted on the platform in real time.

[0054] The advantages of this invention are:

[0055] (1) It can achieve close contact between the detection device and the inner wall of the tunnel, accurately locate the required measuring points, detect 5 measuring lines at the same time, and change the measuring lines and measuring points at any time during the detection process;

[0056] (2) Through the travel unit and terminal platform, the device can switch travel modes, is equipped with tracked walking and retractable lateral rollers, adapts to a variety of complex ground conditions, and can complete travel in different directions such as front, back, left and right, with high flexibility;

[0057] (3) The rotatable frame equipped with the radar probe can adjust the detection angle at any time, and the cross-shaped moving track where the radar connecting rod is located can further change the radar angle.

[0058] (4) The detection range of the device can cover all contours of the tunnel except the ground, and each telescopic arm is equipped with four radar probes to ensure the comprehensiveness and accuracy of the detection data, and can realize the automation and intelligence of the detection process.

[0059] (5) The terminal platform can visualize the collected parameters on this unit platform. By collecting radar data and image information, it can comprehensively realize the analysis and early warning of internal defects and appearance quality of tunnel lining during the construction and operation and maintenance periods.

[0060] If this invention discloses or relates to components or structural parts that are fixedly connected to each other, then, unless otherwise stated, a fixed connection can be understood as: a fixed connection that can be detached (e.g., using bolts or screws), or a fixed connection that cannot be detached (e.g., riveting, welding). Of course, a fixed connection can also be replaced by an integral structure (e.g., manufactured in one piece using a casting process) (except where it is obviously impossible to use an integral molding process).

[0061] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this invention to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.
