[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] Due to the limitation of the weight of the tunnel detection equipment itself, the current tunnel detection equipment is usually fixedly installed on a special carrier train and transported to a designated location for detection by the carrier train. When it is necessary to inspect a trackless tunnel or a tunnel in other special environments, it is difficult to accurately transport the tunnel detection equipment to the designated detection location due to the limitation of the operating environment of the carrier train itself, which makes it impossible to detect.

[0023] In order to solve the above problems, the present invention proposes a box-type detection platform, which aims to solve the problem that the existing tunnel detection equipment is difficult to accurately transport to the designated detection location, resulting in the inability to perform detection.

[0024] like Figure 1 and Figure 2 In one embodiment, the box-type detection platform 100 includes a box body 10, a detection system 20 and a control system 30. The box body 10 is used to be detachably connected to the external carrier 200. A receiving cavity is formed inside the box body 10. The box body 10 has an open state and a closed state. The detection system 20 is arranged in the receiving cavity. The detection system 20 has a working state and a storage state. The control system 30 is arranged in the receiving cavity and is electrically connected to the detection system 20. When the box 10 is in the open state, the control system 30 controls the detection system 20 to switch to the working state and detects the inside of the tunnel. When the box 10 is in the closed state, the control system 30 controls the detection system 20 to switch to the storage state so that the detection system 20 is located in the accommodating cavity as a whole.

[0025] In this embodiment, the box-type detection platform 100 is a device specially designed for tunnel detection work, wherein the box body 10 is used as the bearing structure of the entire box-type detection platform 100, and its profile material can be selected from high-strength alloys to ensure that the internal detection system 20 and control system 30 can be effectively protected under complex working conditions, avoid detection equipment failures caused by damage to the box body 10 structure, and ensure the smooth progress of the detection work. At the same time, the box body 10 can be detachably connected to the external carrier 200, so that it can be conveniently installed on different types of vehicles according to actual needs, such as common rail vehicles or special tunnel detection vehicles, etc., to achieve flexible transportation of the box-type detection platform 100. A accommodating cavity is formed inside the box body 10 for accommodating components such as the detection system 20 and the control system 30 to ensure the installation stability of the above components. At the same time, by integrating the above components in the accommodating cavity, the overall volume of the box-type detection platform 100 is effectively reduced, and the transportation flexibility of the box-type detection platform 100 is further improved. The control system 30 includes a console and an electrical cabinet. When the box 10 is in the open state, the operator can send a work instruction to the detection system 20 through the console to switch the detection system 20 to the working state, and use various detection technologies, such as laser scanning, image acquisition, etc., to conduct detailed detection of the tunnel lining, cracks, water leakage, etc., to ensure the automation and orderliness of the entire detection process. At the same time, the box 10 in the closed state and the detection system 20 in the storage state can prevent the components from being damaged by the external environment, such as dust, collision, etc., thereby increasing the service life of the box-type detection platform 100.

[0026] The present invention proposes a box-type detection platform 100, including a box body 10, a detection system 20 and a control system 30, wherein a receiving cavity is formed inside the box body 10, the detection system 20 and the control system 30 are integrated in the receiving cavity, and the detection system 20 is controlled by the control system 30. By providing the box-type detection platform 100, the integrated arrangement of the detection equipment is realized. At the same time, the detachable connection between the box body 10 and the external carrier 200 greatly improves the mobility and applicability of the box-type detection platform 100, and can be adapted to different carriers 200 to meet the detection requirements of different tunnel projects. Whether it is a straight tunnel or a complex curved tunnel, it can reach the detection site through a suitable carrier 200. It can quickly reach different tunnel detection sites and realize rapid detection. At the same time, when the box-type detection platform 100 is working, the operator can flexibly adjust the working mode and parameters of the detection system 20 through the control system 30 to meet the requirements of various detection tasks and further improve the detection efficiency.

[0027] like Figure 1 and Figure 2In one embodiment, the box body 10 includes a base 11, two side walls 12 and a hatch 13. The two side walls 12 are installed on both sides of the base 11 in the length direction. The hatch 13 can be movably installed between the two side walls 12 to jointly form a accommodating cavity. The hatch 13 can be opened or closed relative to the base 11 so that the box body 10 is in an open state or a closed state.

[0028] In this embodiment, the base 11 is the basic support part of the entire box 10, which provides stable support for the side walls 12, the hatch 13, and the detection system 20 and the control system 30 placed in the accommodating cavity. Usually, the base 11 is made of solid metal materials, such as high-strength steel, to ensure that it can withstand the weight of the entire detection platform during transportation and operation and various forces that may be generated. Two side walls 12 are installed on both sides of the length direction of the base 11, which play the role of side protection and defining the spatial range of the accommodating cavity. Specifically, the side wall 12 is a groove-shaped structure, including a side plate and a baffle around one end of the side plate. This structure further increases the spatial range of the accommodating cavity. At the same time, the setting of the side baffle improves the installation convenience of the hatch 13 and the hatch 13. The hatch 13 can adopt a variety of opening methods, such as the common translation type, double-opening type, etc. The specific opening method will be determined according to the actual use requirements and space layout. By opening the hatch 13, the accommodating chamber inside the box 10 is connected to the outside, and the detection system 20 can be deployed and enter the working state; when the hatch 13 is closed, the accommodating chamber forms a closed space to protect the internal equipment. In this embodiment, the combination of the base 11, the side wall 12 and the hatch 13 makes the formation of the accommodating chamber simple and reasonable, and can effectively accommodate the detection system 20 and the control system 30, providing them with a safe and stable placement space. At the same time, through the simple opening and closing action of the hatch 13, the box 10 can be switched between the open and closed states. This intuitive and easy-to-operate design reduces the difficulty of the operator's work and improves work efficiency.

[0029] like Figure 1 , Figure 2 and Fig.10 In one embodiment, locking pieces are installed at the four corners of the base 11, and the four locking pieces are used to be threadedly connected to the external carrier 200 so that the box body 10 can be detachably connected to the external carrier 200.

[0030] In this embodiment, four locking members (not shown) are fixedly installed at the four corners of the base 11 and are symmetrically distributed, so that the locking members can evenly withstand various forces to which the box 10 is subjected during transportation, including inertial forces generated during acceleration, deceleration, and turning, and impact forces caused by road bumps, thereby improving the connection stability between the box 10 and the external carrier 200. The locking members can be other quick connection structures such as a matching structure of bolts and nuts, a buckle structure, etc. Specifically, mounting seats with threaded holes can be pre-set at the four corners of the base 11, and matching through holes are set at corresponding positions on the external carrier 200. By passing the bolt through the through hole of the carrier 200 and screwing it into the threaded hole of the base 11, and then tightening it with a nut, the box 10 can be reliably connected to the carrier 200; alternatively, the locking piece can be an elastic buckle. When the box 10 needs to be installed on the carrier 200, it is only necessary to align the locking piece with the corresponding position and snap it into the specified position through simple operations to complete the connection; when disassembling, it can be easily separated by triggering a specific unlocking mechanism. Operators can quickly complete the installation and separation of the box 10 and the carrier 200 without special tools or professional skills, which greatly saves working time and improves work efficiency. At the same time, the setting of the locking piece makes the box-type detection platform 100 highly versatile. It can be easily installed on different types of external carriers 200 according to different detection task requirements, meeting the needs of diverse tunnel detection scenarios.

[0031] like Figures 1 to 4 In one embodiment, the hatch 13 is a retractable structure that can be extended or retracted relative to the length direction of the base 11. By controlling its own extension or contraction, the box body 10 can be switched between an open state and a closed state.

[0032] In this embodiment, the extension and retraction of the hatch 13 can be electrically controlled or manually controlled, which is not limited here. When the box 10 needs to be opened, the hatch 13 is sequentially extended outward along the length direction of the base 11 under the action of an external driving force, so that the box 10 enters an open state. When the box 10 needs to be closed, the hatch 13 moves in the opposite direction and sequentially retracts inward to return the box 10 to a closed state. At the same time, the use of a retractable hatch 13 does not require a large opening space to be reserved, and the limited space in the tunnel can be more effectively utilized, so that the box-type detection platform 100 can be more flexibly placed at different positions in the tunnel for detection. At the same time, the retractable hatch 13 has good sealing performance, ensuring that the internal equipment is in a relatively clean and dry environment, reducing the corrosion and failure probability of the equipment, thereby extending the service life of the equipment.

[0033] like Figures 1 to 4In one embodiment, the hatch 13 includes two telescopic brackets and a telescopic protective cover 132, each telescopic bracket includes a plurality of telescopic joints 131; the plurality of telescopic joints 131 are sequentially connected along the length direction of the base 11; The base 11 is provided with two guide rails 111 at intervals. The two guide rails 111 are extended along the length direction of the base 11 . One of the telescopic brackets is slidably disposed on one of the guide rails 111 . The telescopic protective cover 132 covers the two telescopic brackets.

[0034] In this embodiment, the telescopic joint 131 includes two vertical rods 1311, and the two vertical rods 1311 are connected by two connecting rods 1312 that are cross-rotatably connected. When the telescopic joint 131 is subjected to external force, the angle between the two connecting rods 1312 will change, thereby changing the spacing between the two vertical rods 1311, thereby realizing the contraction and extension of the telescopic joint 131. At the same time, the end of the vertical rod 1311 close to the guide rail 111 is connected to a frame 1313, and two rollers 1314 are arranged inside the frame 1313 at intervals. The guide rail 111 is clamped between the two rollers 1314, and the rollers 1314 are used to move the guide rail 111. The wheel 1314 rotates relative to the guide rail 111, driving the telescopic joint 131 to move flexibly on the guide rail 111. At the same time, multiple telescopic joints 131 are connected in sequence to each guide rail 111 to form a telescopic bracket. The telescopic bracket constitutes the basic telescopic skeleton of the hatch 13. At the same time, the external cover is equipped with a telescopic protective cover 132. The protective cover is an accordion structure. When the telescopic bracket is unfolded, the telescopic protective cover 132 will unfold as the telescopic bracket extends to cover the corresponding space; when the telescopic bracket is retracted, the telescopic protective cover 132 will also retract accordingly to ensure that the detection system 20 can work normally.

[0035] like Figure 1 and Figures 5 to 8 In one embodiment, the detection system 20 includes a first detection device 21 and a second detection device 22, and the first detection device 21 and the second detection device 22 are arranged in the accommodating cavity at intervals; The first detection device 21 includes a first mounting frame 211 and a ground penetrating radar 212. One end of the first mounting frame 211 is connected to the base 11, and the other end is equipped with the ground penetrating radar 212. The second detection device 22 includes a second mounting frame 221 and a plurality of visual detection devices 222. The second mounting frame 221 is installed on the base 11, and the plurality of visual detection devices 222 are installed at intervals on the outer peripheral side of the second mounting frame 221.

[0036] In this embodiment, the first mounting frame 211 includes a fixed seat 2111, a first telescopic rod 2112, a rotating connecting member 2113 and a second telescopic rod 2114, wherein one end of the fixed seat 2111 is mounted on the base 11, and the other end is rotatably connected to one end of the first telescopic rod 2112, and an electric push rod is connected between the two, and the first telescopic rod 2112 is driven to rotate relative to the fixed seat 2111 through the extension and contraction of the electric push rod itself, and the first telescopic rod 2112 is built-in with a driving motor to drive the first telescopic rod 2112 to perform multi-stage extension and contraction; the rotating connecting member 2113 includes a mounting portion 2113a and a rotating portion 2113b, wherein the mounting portion 2113a is fixedly mounted on the other end of the first telescopic rod 2112, and the peripheral side of the mounting portion 2113a is mounted A driving motor is provided, and a rotating portion 2113b is rotatably connected to one end of the mounting portion 2113a away from the first telescopic rod 2112, and at the same time, a driving motor on the peripheral side of the mounting portion 2113a can drive the rotating portion 2113b to rotate relative to the mounting portion 2113a, and at the same time, a driving motor is also installed on the peripheral side of the rotating portion 2113b, and the second telescopic rod 2114 includes a mounting section 2114a and a telescopic section 2114b, wherein one end of the mounting section 2114a is rotatably connected to the rotating portion 2113b, and a driving motor on the peripheral side of the rotating portion 2113b can drive the mounting section 2114a to rotate relative to the rotating portion 2113b, wherein a rotation direction of the rotating portion 2113b relative to the mounting portion 2113a and a rotation direction of the mounting section 2114a relative to the rotating portion 2113b are perpendicular to each other. At the same time, a driving motor is installed at the other end of the installation section 2114a, and a transmission gear is installed on the extended shaft of the driving motor. The telescopic section 2114b is provided with a rack along its length direction, and the telescopic section 2114b is telescoped relative to the installation section 2114a through the meshing transmission of the transmission gear and the gear. At the same time, a plurality of ground penetrating radars 212 are arranged at intervals on the outer peripheral side of the telescopic section 2114b. Specifically, the ground penetrating radar 212 is rotatably connected to the telescopic section 2114b, and a driving motor is installed at the connection between the two to drive the ground penetrating radar 212 to swing relative to the telescopic section 2114b.

[0037] Through the multi-stage extension and multi-angle rotation of the first mounting frame 211, the ground penetrating radar 212 can move to any position on the inner wall of the tunnel and detect the geological structure inside the tunnel. Specifically, the ground penetrating radar 212 uses the propagation characteristics of electromagnetic waves in different media. When encountering a medium interface with different dielectric constants, reflection will occur. By analyzing the time, amplitude, waveform and other information of the reflected wave, the characteristics of the underground structure can be inferred, such as whether there are gaps or cavities.

[0038] In this embodiment, the second mounting frame 221 is a semi-annular structure, and the visual inspection device 222 can be an array camera. The array camera has high resolution, high frame rate and good low-light performance, so that images can be clearly captured even in a relatively dark environment in the tunnel. They are arranged in a spacer ring on the outer peripheral side of the second mounting frame 221, and can perform all-round image acquisition of the tunnel wall. Through the cooperation between different cameras, complete image information of the tunnel wall can be obtained, and the surface condition of the tunnel wall can be detected at the same time, such as whether there are cracks, peeling, water leakage, etc. Through the analysis of the captured image, the damage of the tunnel wall can be evaluated. Through the cooperation of the first detection device 21 and the second detection device 22, a comprehensive detection capability is provided for tunnel detection, and detailed detection can be performed on the tunnel wall from underground to above the ground.

[0039] like Figure 1 and Figures 5 to 8 In one embodiment, the detection system 20 includes at least two first detection devices 21, and the at least two first detection devices 21 are arranged in the accommodating cavity at intervals along the length direction of the base 11; And / or, the control system 30 includes at least two second detection devices 22 , and the at least two second detection devices 22 are disposed in the accommodating cavity at intervals along the length direction of the base 11 .

[0040] In this embodiment, the specific number of the first detection devices 21 can be two, three or four, and the specific number is not limited here. By setting a plurality of first detection devices 21, it can cover a wider area, avoiding the problem of limited detection range of a single first detection device 21, and improving the detection efficiency. At the same time, the first detection device 21 can be extended and rotated by its own mounting frame, so that the ground penetrating radar 212 of each first detection device 21 is located at a different position, further increasing the detection range, thereby improving the detection efficiency.

[0041] With or without the above-mentioned embodiments, the specific number of the second detection devices 22 can be two, three or four, and the specific number is not limited here. By setting a plurality of second detection devices 22, the plurality of second detection devices 22 can collect images of the tunnel wall from different positions at multiple angles. The plurality of array cameras in each second detection device 22 can capture different parts of the tunnel wall according to their positions and angles, and form image information from multiple perspectives. This improves the comprehensiveness and meticulousness of image acquisition.

[0042] like Figure 1 and Figures 5 to 8In one embodiment, the box-type detection platform 100 also includes at least two sliding components 40, and a sliding component 40 is provided between the first detection device 21 and the second detection device 22 and the base 11, so that the first detection device 21 and the second detection device 22 can slide in the width direction relative to the base 11.

[0043] In this embodiment, the sliding assembly 40 includes a slider 41, a screw motor 42 and a slide rail 43, wherein the slide rail 43 is laid on the base 11, the slider 41 is slidably arranged on the guide rail 111, and the screw motor 42 is drivingly connected to the slider 41. By starting the electric cylinder of the screw motor 42, the screw is driven to rotate, and then the slider 41 is driven to move on the screw, so as to realize the sliding of the first detection device 21 and the second detection device 22 connected thereto. In this way, the first detection device 21 and the second detection device 22 slide along the width direction of the base 11, and then the first detection device 21 and the second detection device 22 can be dynamically adjusted as needed, so as to better adapt to different tunnel environments and detection requirements, and improve the accuracy of detection.

[0044] In other embodiments, the box-type detection platform 100 also includes a rotating assembly 50, which includes a transmission motor 51, a first gear 52 and a second gear 53, wherein the transmission motor 51 is installed on the second mounting frame 221, the first gear 52 is installed on the output shaft of the transmission motor 51, and the second gear 53 is installed on the top of the slider 41 and meshes with the first gear 52. By starting the transmission motor 51, the first gear 52 rotates, thereby driving the second gear 53 and the second detection device 22 above the second gear 53 to rotate, thereby further improving the detection range of the second detection device 22.

[0045] In one embodiment, the box-type detection platform 100 further includes a third detection device (not shown), which includes a lifting frame and a carrying platform, one end of the lifting frame is mounted on the base 11, and the carrying platform is mounted on the other end of the telescopic frame, and the carrying platform is used to carry external staff; And / or, the box-type detection platform 100 also includes a fourth detection device, which includes a base 61 and a laser detection component 62. The base 61 is installed on the side of any side wall 12 away from the accommodating cavity, and the laser detection component 62 is installed on the base 61. The laser detection component 62 is used to detect the deformation of the external tunnel.

[0046] like Figure 1 and Fig. 9In one embodiment, in this embodiment, the lifting frame can adopt a hydraulic lifting system, an electric lifting system or a mechanical lifting structure, such as a scissor-type lifting frame or a telescopic lifting rod, etc., to adjust the load-bearing platform to different heights, so as to facilitate external staff to perform inspection work at different heights. The load-bearing platform can be made of solid metal or composite materials to ensure the safety of personnel operating on it. It is installed at the other end of the lifting frame and can be raised and lowered as needed, so that the staff can reach different heights, which is convenient for manual inspection, maintenance or auxiliary inspection operations at high positions in the tunnel.

[0047] With or without the above-mentioned embodiments, the box-type detection platform 100 also has a fourth detection device, in which the base 61 is installed on the side of the side wall 12 away from the accommodating cavity to provide stable support for the laser detection component 62, thereby ensuring the overall stability of the fourth detection device. At the same time, the laser detection component 62 is positioned in a suitable position so that it can effectively detect the deformation of the external tunnel. The laser detection component 62 determines whether the tunnel wall has been deformed by emitting a laser beam and measuring the changes in parameters such as the time, angle or frequency of the laser beam reflected back. For example, when the tunnel wall undergoes a slight displacement or deformation, the laser detection component 62 can detect the changes in the angle or distance of the laser reflection, thereby calculating the deformation of the tunnel.

[0048] In this embodiment, the third detection device and the fourth detection device complement the original first detection device 21 and the second detection device 22 to form a more complete tunnel detection system. The combination of multiple detection methods can conduct a full range of inspections on the tunnel from different angles, different positions and different methods, further improving the comprehensiveness and accuracy of the detection.

[0049] like Fig.10 In one embodiment, the present invention further proposes a box-type detection device, which includes a carrier 200 and a box-type detection platform 100, wherein the carrier 200 can be selected from different types according to different working environments, such as a container trailer or a railway shared flat car, to ensure that the box-type detection platform 100 is accurately and quickly transported to a designated location without being restricted by the location of a tunnel. The specific structure of the box-type detection platform 100 refers to the above embodiment. Since the box-type detection platform 100 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0050] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
