Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0033] The subway tunnel scenarios can be divided into the pre-track-laying acceptance stage (without rails), the pre-opening acceptance stage (with rails), and the operation stage (with rails). When the existing tunnel inspection vehicle changes the inspection site, it needs to rely on a small crane to lift and transport the tunnel inspection vehicle to the inspection site, and the transfer handling is not flexible enough, affecting the inspection efficiency.

[0034] The present invention provides a lightweight and modular tunnel inspection vehicle, aiming to achieve the rapid disassembly and assembly of the lightweight and modular tunnel inspection vehicle and improve the inspection efficiency.

[0035] Please refer to Figures 1 to 7 , in an embodiment of the present invention, the lightweight and modular tunnel inspection vehicle 100 is used to detect diseases of the tunnel to be inspected. The lightweight and modular tunnel inspection vehicle 100 includes a frame assembly 1, a control console 2, a diagnostic assembly 3, and a traveling assembly 4. The control console 2 is connected to a surface of the frame assembly 1; the diagnostic assembly 3 is connected to a surface of the frame assembly 1, the diagnostic assembly 3 is spaced from the control console 2, and the diagnostic assembly 3 is electrically connected or communicatively connected to the control console 2; the traveling assembly 4 includes a driving member 41 and two wheel sets 42. The driving member 41 is connected to another surface of the frame assembly 1 facing away from the control console 2, the driving member 41 is electrically connected or communicatively connected to the control console 2, the two wheel sets 42 are rotatably connected to another surface of the frame assembly 1 facing away from the control console 2, the two wheel sets 42 are spaced apart, and a driving end of the driving member 41 is drivingly connected to a wheel set 42 to make the wheel set 42 rotate relative to the frame assembly 1; at least one of the control console 2, the diagnostic assembly 3, and the traveling assembly 4 is detachably connected to the frame assembly 1.

[0036] In this embodiment, since at least one of the console 2, the diagnostic component 3, and the traveling component 4 is detachably connected to the frame component 1, when it is necessary to change the detection site, the staff can quickly disassemble these components from the frame. For example, after disassembling the console 2 and the diagnostic component 3, their volume and weight will be significantly reduced, which is convenient for manual handling or transfer using small transportation tools, eliminating the need to rely on large cranes for hoisting and greatly shortening the transfer time. The detachable connection of at least one of the console 2, the diagnostic component 3, and the traveling component 4 to the frame component 1 makes the lightweight and modular tunnel inspection vehicle 100 more flexible in transferring between different sites. In some detection sites with limited space or narrow roads, large cranes may not be able to enter. By disassembling some components, the inspection vehicle can enter these sites more easily, improving the applicable range of the inspection vehicle and enhancing its working ability in complex environments. The console 2, the diagnostic component 3, and the traveling component 4 are independent of each other and detachably connected to the frame component 1. When a certain component fails, it can be disassembled separately for repair or replacement without the need to disassemble the entire lightweight and modular tunnel inspection vehicle 100 on a large scale, saving maintenance time and costs. The detachable connection method makes the maintenance work more convenient. During regular maintenance, the staff can easily disassemble each component to clean, lubricate, and inspect the internal parts. For example, after disassembling the wheelset 42 and the driving component 41 of the traveling component 4, the dirt in the bearings of the wheelset 42 can be cleaned more thoroughly, and the wear condition of the transmission components of the driving component 41 can be inspected, thus ensuring the normal operation of the inspection vehicle and extending the service life of the equipment.

[0037] The technical solution of the present invention realizes the rapid disassembly and assembly of the entire lightweight and modular tunnel inspection vehicle 100 through the detachable connection between the console 2 and the frame component 1, the detachable connection between the diagnostic component 3 and the frame component 1, and the detachable connection between the traveling component 4 and the frame component 1, thereby achieving the effect of rapid site transfer and improving the detection efficiency.

[0038] Please refer to Figure 4 , in the embodiment of the present invention, the frame component 1 includes a first frame 11, a second frame 12, and a seat 13. One side of the first frame 11 is detachably connected to one side of the second frame 12, and the seat 13 is detachably connected to the first frame 11 and the second frame 12 respectively.

[0039] In this embodiment, the first frame 11 and the second frame 12 are detachably connected, enabling the frame assembly 1 to be partially disassembled and assembled according to actual needs. At the entrance of some narrow inspection sites, the entire frame assembly 1 may not be able to pass through. In this case, the first frame 11 and the second frame 12 can be disassembled first, and then they can be moved into the inspection site separately and reassembled. This partial disassembly and assembly method further improves the adaptability of the lightweight and modular tunnel inspection vehicle 100 in complex environments, enabling it to more flexibly respond to various site conditions. The seat 13 is detachably connected to the first frame 11 and the second frame 12 respectively, facilitating the adjustment of the seat 13 by the staff according to the requirements of the inspection task. In some inspection scenarios, it may be necessary to increase the number of seats 13 to accommodate more staff, or to adjust the position of the seat 13 for better observation of the inspection equipment. Through the detachable connection, the staff can quickly disassemble the original seat 13, install a new seat 13 or adjust the seat layout, improving the comfort and work efficiency of the inspection work.

[0040] During transportation or storage, the first frame 11 and the second frame 12 can be disassembled, and the seat 13 can also be removed from the frame. Then, these components can be stacked or arranged compactly. Stacking the first frame 11 and the second frame 12 can significantly reduce the occupied space. Compared with traditional non-detachable frames, this detachable design enables the lightweight and modular tunnel inspection vehicle 100 to save more space when not in use, facilitating storage and transportation, and reducing the warehousing and transportation costs. The detachable connection between the first frame 11 and the second frame 12 facilitates the maintenance of the frame assembly 1. If a certain part of the first frame 11 is damaged or needs to be upgraded, the first frame 11 can be disassembled separately for repair or replacement of components, without the need for large-scale disassembly of the entire frame assembly 1. This not only saves maintenance time and costs but also reduces the impact of maintenance work on the progress of the inspection task.

[0041] Please refer to again Figure 4 , in the embodiment of the present invention, the first frame 11 and the second frame 12 are respectively provided with through first connection holes, and the first connecting member 111 passes through the two first connection holes to connect the first frame 11 and the second frame 12 into one body;

[0042] One of the first frame 11 and the second frame 12 is provided with a guiding convex 113 facing the other, and the other is provided with a guiding hole. When the first frame 11 and the second frame 12 are connected, the guiding convex 113 is inserted into the guiding hole.

[0043] In this embodiment, the design of the guiding protrusion 113 and the guiding hole enables the accurate positioning and alignment of the first vehicle frame 11 and the second vehicle frame 12 during connection. When the guiding protrusion 113 passes through the guiding hole, it plays a role of guiding and calibration, ensuring that the connection holes of the two vehicle frames can accurately correspond. This precise alignment method can effectively avoid problems such as loose connection and uneven force caused by misalignment of the connection holes, thereby enhancing the overall stability of the connection of the vehicle frames. In a preferred embodiment, a chamfer is provided at the end of the guiding protrusion 113 for guiding the guiding protrusion 113 to pass through the guiding hole and improving the connection speed. The cooperation between the guiding protrusion 113 and the guiding hole not only plays a positioning role during connection but also enhances the torsional resistance of the vehicle frame after connection. When the vehicle frame is subjected to external forces and undergoes torsion, the close cooperation between the guiding protrusion 113 and the guiding hole can effectively limit the torsional deformation of the vehicle frame, enabling the vehicle frame to better withstand various loads. This helps to improve the reliability and safety of the lightweight and modular tunnel inspection vehicle 100 under complex working conditions and extend the service life of the equipment.

[0044] As Figure 4 shown, in the embodiment of the present invention, the seat 13 includes a main body portion 131 and two connecting portions 132. One end of each of the two connecting portions 132 is connected to a surface of the main body portion 131, and a through hole is provided at the other end of the connecting portion 132;

[0045] Guiding columns 115 are respectively protruded from the surfaces of the first vehicle frame 11 and the second vehicle frame 12. The guiding column 115 of the first vehicle frame 11 passes through the through hole of one connecting portion 132, and the guiding column 115 of the second vehicle frame 12 passes through the through hole of the other connecting portion 132;

[0046] Through holes are respectively provided with through second connection holes on the hole walls and the guiding columns 115. One end of a second connecting member 117 passes through the two second connection holes to connect the connecting portion 132 and the guiding column 115, and a protrusion 1171 is provided at the other end of the second connecting member 117. The protrusion 1171 is clamped on the outer edge of the second connection hole.

[0047] In this embodiment, through the cooperation between the guiding column 115 and the through hole, the connecting portion 132 of the seat 13 can be accurately positioned on the first vehicle frame 11 and the second vehicle frame 12. When the guiding column 115 passes through the through hole, this structure not only provides a stable support point for the seat 13 but also ensures the correct installation position of the seat 13 on the vehicle frame; combined with the second connecting member 117 passing through the second connection hole and clamping the protrusion 1171 on the outer edge of the second connection hole, the connection strength between the seat 13 and the vehicle frame is further enhanced. This stable connection method can effectively prevent the seat 13 from shaking or shifting during vehicle driving due to bumps or sudden braking, ensuring the safety and comfort of the staff during operation.

[0048] This connection method of the seat 13 makes the installation process simple and fast. The staff only needs to align the through hole of the connecting part 132 with the guiding column 115 on the vehicle frame and insert it, and then pass the second connecting piece 117 through the second connecting hole and make the protrusion 1171 snap into the outer edge, then the installation of the seat 13 can be completed. This fast installation method greatly saves the installation time and improves the work efficiency. Especially when it is necessary to frequently change the detection site or perform equipment maintenance, the seat 13 can be quickly installed in place, reducing the delay of the detection work caused by the cumbersome installation process.

[0049] In an embodiment of the present invention, the other end of the second connecting piece 117 is rotatably connected with a limiting part 1172. The limiting part 1172 has a fixed state of buckling one end of the second connecting piece 117 and a release state of being away from one end of the second connecting piece 117. When one end of the second connecting piece 117 passes through the two second connecting holes, the limiting part 1172 rotates and switches to the fixed state to limit the second connecting piece 117 in the second connecting hole.

[0050] In this embodiment, the other end of the second connecting piece 117 is provided with a limiting part 1172. The limiting part 1172 is rotatably connected with the other end of the second connecting piece 117. The design of the limiting part 1172 can effectively prevent the second connecting piece 117 from loosening from the second connecting hole due to vibration or other reasons during use. When one end of the second connecting piece 117 passes through the two second connecting holes, the limiting part 1172 rotates and switches to the fixed state, firmly limiting the second connecting piece 117 in the second connecting hole and enhancing the connection strength. The rotational switching design of the limiting part 1172 makes the locking and unlocking operations of the connecting piece simpler and faster. The staff only needs to perform a simple rotational operation to fix or release the second connecting piece 117, without the need to use additional tools or complex operation steps. This fast locking and unlocking function greatly improves the assembly and disassembly efficiency. Especially in the detection tasks that require frequent disassembly and assembly of the vehicle frame assembly 1, a large amount of time and labor can be saved.

[0051] In an embodiment of the present invention, the control console 2 is provided with a locking component 21, and a buckle is provided on one surface of the vehicle frame assembly 1 facing the control console 2. The locking component 21 is used for buckling connection with the buckle to lock and press the control console 2 on the vehicle frame assembly 1.

[0052] In this embodiment, the snap - fit connection method between the latch assembly 21 and the buckle can firmly lock and press the console 2 onto the frame assembly 1, preventing the console 2 from shifting or shaking during vehicle operation due to vibrations, bumps, etc. This stable fixing method is crucial for ensuring the smooth progress of the detection work. Since the console 2 usually integrates numerous control buttons, display screens, and operation interfaces, any slight displacement may affect the operation accuracy and the reliability of the detection data. The design of the latch assembly 21 and the buckle makes the installation process of the console 2 simple and fast. The staff only needs to align the console 2 with the buckle position on the frame assembly 1 and then perform the snap - fit operation through the latch assembly 21 to complete the installation of the console 2. This fast installation method greatly saves the installation time and improves work efficiency. Especially when it is necessary to frequently change the detection site or perform equipment maintenance, the console 2 can be quickly installed in place, reducing the delay of the detection work caused by the cumbersome installation process.

[0053] In an embodiment of the present invention, a positioning hole is formed on the surface of the console 2 facing the frame assembly 1, and a positioning pin 118 protrudes from one surface of the frame assembly 1. When the console 2 is connected to the frame assembly 1, the positioning pin 118 passes through the positioning hole.

[0054] In this embodiment, the cooperation between the positioning hole and the positioning pin 118 can ensure the accurate positioning of the console 2 when it is installed on the frame assembly 1. When the positioning pin 118 passes through the positioning hole, the positional relationship between the console 2 and the frame assembly 1 is precisely determined, avoiding problems such as loose connection and tilted operation interface caused by installation position deviation. After the positioning pin 118 penetrates into the positioning hole, it not only plays a positioning role but also enhances the connection stability between the console 2 and the frame assembly 1 to a certain extent. The tight fit between the positioning pin 118 and the positioning hole can effectively prevent the console 2 from shifting horizontally due to vibrations during vehicle operation. Combined with the vertical fixing of the latch assembly 21 and the buckle, it forms an all - around stable connection. In a preferred embodiment, a chamfer is provided at the end of the positioning pin 118 to guide the positioning pin 118 through the positioning hole and improve the connection speed.

[0055] In an embodiment of the present invention, the diagnostic assembly 3 is provided with a third connection hole, and the frame assembly 1 is provided with a corresponding fourth connection hole. The third connector 32 passes through the third connection hole and the fourth connection hole respectively to connect the diagnostic assembly 3 to the frame assembly 1.

[0056] In this embodiment, the diagnostic component 3 can be accurately fixed to the frame component 1 by passing the third connecting member 32 through the third connecting hole and the fourth connecting hole. This connection method is similar to the common bolt connection, which can provide sufficient connection strength and stability to ensure that the diagnostic component 3 can maintain a stable working state under various working conditions during the vehicle driving process. When the diagnostic component 3 needs to be maintained, repaired or replaced, the third connecting member 32 only needs to be removed from the third connecting hole and the fourth connecting hole to quickly remove the diagnostic component 3 from the frame component 1. This quick disassembly method greatly saves maintenance time and labor and improves the maintainability of the equipment.

[0057] In the embodiment of the present invention, the number of the diagnostic components 3 is multiple, and the multiple diagnostic components 3 include a hidden disease detection device, an apparent disease detection device, and a deformation detection device, and each diagnostic component 3 is provided with a third connection hole;

[0058] The frame assembly 1 is provided with a plurality of fourth connection holes, and one of the plurality of diagnosis assemblies 3 is installed in the fourth connection hole.

[0059] In this embodiment, the lightweight, modular tunnel inspection vehicle 100 can be equipped with a variety of diagnostic components 3, including but not limited to a hidden disease detection device for detecting the inner wall surface of the tunnel, an apparent disease detection device for detecting the inner wall surface of the tunnel, and a deformation detection device for detecting the overall deformation degree of the tunnel. Accordingly, a plurality of fourth connection holes are provided on the frame component 1 for connecting with diagnostic components 3 of different sizes and types, thereby enriching the detection items and functionality of the lightweight, modular tunnel inspection vehicle 100.

[0060] In an embodiment of the present invention, four spaced-apart clamps 14 are protruded from the other surface of the frame assembly 1 away from the driver's console 2, and the wheelset 42 includes a rotating shaft and two wheels arranged at both ends of the rotating shaft, and two clamps 14 are rotatably connected to a rotating shaft.

[0061] In this embodiment, the wheelset 42 and the frame assembly 1 are connected by a clamp 14 to achieve a detachable connection between the wheelset 42 and the frame assembly 1. The wheelset 42 includes a rotating shaft and two wheels connected to both ends of the rotating shaft. The two clamps 14 located on the same horizontal line on both sides of the frame assembly 1 are rotatably connected to the rotating shaft of one wheelset 42, and the connection is more stable.

[0062] 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.
