Technical Field
[0001] This invention relates to the field of infrastructure construction quality inspection, and specifically to an intelligent safety protection system based on tunnel inner wall inspection. Background Technology
[0002] Tunnel interior wall inspection is a crucial task aimed at assessing the integrity, structure, and safety of the tunnel's interior walls. It typically involves a variety of techniques and methods, including non-destructive testing (NDT), infrared imaging, and ultrasonic testing. These techniques help inspectors determine the extent of corrosion, cracks, spalling, and other potential problems on the interior walls, covering the entire tunnel interior surface.
[0003] The wall-climbing inspection robot is equipped with inspection equipment and cameras mounted on the front of an adsorption chassis to inspect the inner wall of a tunnel. It can be used in the tunnel construction and maintenance phases.
[0004] However, existing robots face challenges in providing power and pose significant safety risks when performing comprehensive inspections of the entire tunnel wall. Furthermore, the robot's stability is affected by factors such as its own technology, signal interference, temperature, and humidity, increasing the risk of falls. Therefore, it is necessary to install appropriate safety ropes inside the tunnel to suspend the robot and prevent falls.
[0005] However, there are generally no attachments on the top of the tunnel, so conventional safety rope measures cannot be implemented; or there are pre-buried safety anchor points, which require multiple climbing operations to change the safety rope anchor points according to the robot's movement position. This kind of operation increases the safety risks for workers.
[0006] Therefore, existing tunnel interior wall inspection methods suffer from low reliability due to the aforementioned technical deficiencies. Thus, improving the reliability of tunnel interior wall inspection methods is a problem that needs to be solved in this field. Summary of the Invention

[0021] The worm gear motor is connected to the winding reel via a second coupling to control the speed of the winding reel. By controlling the speed of the winding reel, the robot device for inspecting the tunnel wall can be supplied with a cable of the appropriate length.
[0022] Furthermore, the hanging rope assembly includes a cable, a cable fixing block, a cable guide wheel, a battery box, a first sheet metal plate, a cable friction wheel shaft, a circuit box, a lifting eye fixing sheet metal, a lifting eye, a second sheet metal plate, a friction wheel, a motor fixing sheet metal, a first coupling, a diamond-shaped bearing seat, a cable guide wheel shaft, and a geared motor;

Detailed Implementation
[0050] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.
[0051] The intelligent safety protection system based on tunnel inner wall detection provided by this invention is described in [reference needed]. Figures 1-2 It includes a slide rail device 1, an intelligent rope winding and unwinding device 2, a tunnel inner wall inspection robot device 3, a transport trolley device 4, a control device 5, and a UWB positioning base station 6.
[0052] The intelligent rope retraction system 2, based on the distance between the tunnel wall inspection robot 3 and the slide rail device 1, is controlled by the control device 5 to automatically retract and extend the rope. This system can tighten the rope after the tunnel wall inspection robot 3 falls, preventing it from falling to the ground and causing damage to the tunnel wall inspection robot 3, while also further ensuring the safety of personnel.
[0053] The UWB positioning base station 6 is connected in conjunction with the sliding rail device 1, the intelligent rope retraction device 2, the tunnel inner wall inspection robot device 3, and the transport trolley device 4. This allows for real-time acquisition of the coordinate positions of the sliding rail device 1, the intelligent rope retraction device 2, the tunnel inner wall inspection robot device 3, and the transport trolley device 4. The acquired coordinate positions are then transmitted to the control device 5. The control device 5 uses these coordinate positions to control the sliding rail device 1, the intelligent rope retraction device 2, the tunnel inner wall inspection robot device 3, and the transport trolley device 4 to move synchronously, ensuring they are all on the same longitudinal section of the tunnel. This avoids the need for repeated climbing to safety rope anchoring points. The tunnel inner wall inspection robot device 3 can traverse the entire tunnel inner wall without any safety risks.
[0054] See Figure 3 The slide rail device 1 is installed at the top of the tunnel and connected to the control device 5. The control device 5 can control the displacement of the slide rail device 1. It includes a cross plate 11, a slide rail housing 12, a track groove 13, a slide rail wheel 14, a slide rail wheel motor 15, a slide hook 16, and a slide hook positioning label 17.
[0055] The upper part of the slide rail housing 12 is arranged along the Y-axis direction of the tunnel (see...). Figure 1 It is fixedly connected to the inner wall of the tunnel to bear the weight of the slide rail device 1.
[0056] The slide rail housing 12 has a hollow interior for mounting the horizontal plate 11, the slide rail wheel 14, and the slide rail wheel motor 15. The middle part is a protruding part, and the two sides are symmetrical track grooves.
[0057] Here, the connection method between the slide rail housing 12 and the tunnel inner wall is not limited in this solution; it can be fixed by means of bonding or bolting.
[0058] The horizontal plate 11 is provided on the protruding part of the slide rail housing 12, and its two ends are corresponding to the track groove 13. The slide rail wheel 14 is provided on both ends of the horizontal plate 11 and embedded in the track groove 13. It can move along the track groove 13 in the track groove 13, and at the same time drive the horizontal plate 11 to move along the protruding part of the slide rail housing 12.
[0059] The slide rail motor 15 is connected to the control device 5, and the slide rail motor 15 is respectively set at both ends of the horizontal plate 11 and driven by the slide rail 14 at the bottom. The control device 5 controls the slide rail motor 15 to provide driving force for the slide rail 14 to move along the track groove 13.
[0060] The connecting end of the sliding hook 16 is located at the bottom of the horizontal plate 11, and the hook end passes through the slide rail housing 12 and is located outside the slide rail housing 12, for use in conjunction with the intelligent rope retraction system device 2.
[0061] The sliding hook positioning tag 17 is set on the sliding hook 16 and transmits signals in real time with multiple base stations of the UWB positioning base station 6 to determine the real-time spatial position of the sliding hook positioning tag 17.
[0062] The intelligent rope retraction system 2 is connected in conjunction with the control device 5. It is used to control the automatic rope retraction and release of the tunnel inner wall inspection robot device 3 according to the distance between the tunnel inner wall inspection robot device 3 and the hanging point. This ensures that the tunnel inner wall inspection robot device 3 is kept taut in real time, avoids the tunnel inner wall inspection robot device 3 from falling, and improves safety.
[0063] The intelligent rope retraction system device 2 includes a rope hanging assembly and a cable base assembly 22. The rope hanging assembly 21 is connected to the hook 16 of the slide rail device 1, and the cable base assembly 22 provides a cable to the rope hanging assembly 21. The cable is connected to the tunnel inner wall inspection robot device 3 through the rope hanging assembly 21.
[0064] When the tunnel wall inspection robot device 3 falls, the force of the fall is transmitted to the slide rail device 1 through the hanging rope assembly 21, and finally to the adhesive force between the slide rail housing 12 and the tunnel top. This can tighten the tunnel wall inspection robot device 3 after it falls, preventing it from falling to the ground and causing damage to the tunnel wall inspection robot device 3, while further ensuring the safety of personnel.
[0065] The cable base assembly 22 is mounted on the transport trolley device 4 and connected to the control device 5. Under the control of the control device 5, it can provide cable to the rope assembly 21. See also Figure 4 The cable base assembly 21 includes a bracket 221, a second battery 222, a second coupling 223, a cable reel 224, a worm gear motor 225, a base plate 226, a base 227, and a circuit control box 228.
[0066] The bracket 221 serves as a mounting base, and the cable base assembly 22 is mounted on the transport trolley device 4 via the bracket 221. Inside the bracket 221, a base 227, a second battery 222, and a circuit control box 228 are arranged sequentially.
[0067] The circuit control box 228 is used to house the control circuitry that enables the operation of the cable base assembly 22.
[0068] The base 227 is mounted on the circuit control box 228, and the second battery 222 is located inside the base 227 to supply power to the cable base assembly 22.
[0069] The base plate 226 is mounted above the bracket 221 and serves as the base for the worm gear motor 225, the second coupling 223, and the winding reel 224.
[0070] The worm gear motor 225 is connected in cooperation with the control device 5. Under the command issued by the control device 5, the worm gear motor 225 can be controlled to achieve the corresponding speed so as to release the cable of the corresponding length.
[0071] The worm gear motor 225 is connected to the winding reel 224 via the second coupling 223 to control the rotation speed of the winding reel 224. By controlling the rotation speed of the winding reel 224, the corresponding length of cable is provided to the tunnel inner wall inspection robot device 3.
[0072] The cable provided by the cable base assembly 22 has one end connected to the cable base assembly 22 and the other end connected to the tunnel inner wall inspection robot device 3 via the rope assembly 21.
[0073] See Figure 5 The lanyard assembly includes a cable 211, a cable fixing block 212, a cable guide wheel 213, a battery box 214, a first sheet metal plate 215, a cable friction wheel shaft 216, a circuit box 217, a lifting ring fixing sheet metal 218, a lifting ring 219, a second sheet metal plate 2110, a friction wheel 2111, a motor fixing sheet metal 2112, a first coupling 2113, a diamond bearing seat 2114, a cable guide wheel shaft 2115, and a geared motor 2116.
[0074] The first sheet metal sheet 215 and the second sheet metal sheet 2110 are arranged opposite each other, forming an installation area in the middle, and a hanging ring is provided at the top to fix the sheet metal sheet 218 to connect the first sheet metal sheet 215 and the second sheet metal sheet 2110.
[0075] The lifting ring 219 is set on the lifting ring fixing sheet metal 218. The hanging rope assembly 21 can be connected to the sliding hook 16 in the slide rail device 1 through the lifting ring 219, and the hanging rope assembly 21 can move synchronously with the slide rail device 1.
[0076] The friction wheel 2111 is disposed in the installation area formed by the first sheet metal sheet 215 and the second sheet metal sheet 2110, and its two ends are connected to the first sheet metal sheet 215 and the second sheet metal sheet 2110 through the cable friction wheel shaft 216, and can rotate between the first sheet metal sheet 215 and the second sheet metal sheet 2110.
[0077] The cable guide wheel 213 is located below the friction wheel 2111. Its end is provided with a cable guide wheel shaft 2115, a diamond-shaped bearing seat 2114 and a first coupling 2113 to form a transmission assembly. A reduction motor 2116 is set in cooperation with the first coupling 2113. The reduction motor 2116 is connected to the lifting ring fixing sheet metal 218 through the motor fixing sheet metal 2112. The reduction motor 2116 is connected in cooperation with the control device 5. The control device 5 issues commands to the reduction motor 2116, and the reduction motor 2116 controls the transmission assembly to drive the speed of the cable guide wheel 213.
[0078] A transmission channel for cable 211 is formed between cable guide wheel 213 and friction wheel 2111. Cable 211 passes through the two, and the mutual squeezing action of the two effectively controls the release length of the cable rope.
[0079] The cable fixing block 212 is installed at the lower part between the first sheet metal plate 215 and the second sheet metal plate 2110 to control the direction of cable 211 exiting the rope.
[0080] After the cable passes through the cable guide wheel 213 and the friction wheel 2111, the cable fixing block 212 guides and fixes the cable 211 to prevent the cable 211 from deviating between the cable guide wheel 213 and the friction wheel, which would prevent the cable 211 from being released or retracted, thus affecting the reliability of the device.
[0081] The battery box 214 is installed on one side of the first sheet metal plate 215 to provide power to the hanging rope device 21. The circuit box 217 is fixed to the hanging ring sheet metal 218, which is used to house the control circuit that enables the operation of this hanging rope assembly 21.
[0082] The cable base assembly 22 and the cable hanging rope assembly 21 must keep the cable winding and unwinding state and length synchronized. Specifically, the control device 5 is used to synchronously control the rotation state of the geared motor 2116 on the hanging rope assembly and the worm gear motor 225 on the cable base assembly.
[0083] As an example, let the diameter of the cable guide wheel 213 be d1, the rotation speed be n1, and the number of rotations be p1; and the diameter of the winding reel 224 be d2, the rotation speed be n2, and the number of rotations be p2. Then the control device 5 needs to ensure that n1 / n2 = d1 / d2, so that the rotation strokes of the two are consistent.
[0084] Further, see Figures 6-7The tunnel wall inspection robot device 3 includes an inspection component 31, a chassis component 32, an adsorption component 33, and a robot positioning tag component 34.
[0085] The detection component 31 is installed at the front end of the chassis component 32 and is used for tunnel inner wall inspection. The adsorption component 33 is installed below the chassis component 32 and is adsorbed onto the tunnel inner wall by relying on the principle of negative pressure.
[0086] The robot positioning tag 34 component is installed on the upper part of the chassis component 32. It determines the real-time spatial position of the tunnel inner wall detection robot 3 by exchanging signals with multiple base stations of the UWB positioning base station 6 in real time.
[0087] The specific structure and working principle of the tunnel wall inspection robot are well known to those skilled in the art, and will not be described in detail here.
[0088] See Figure 8 The trolley device 4 includes a power supply assembly 41, a trolley chassis 43, trolley wheels 44, and a trolley positioning tag 42.
[0089] The trolley wheels 44 are symmetrically arranged below the trolley chassis 43. The displacement of the trolley transport device 4 can be achieved by setting the trolley wheels 44.
[0090] The vehicle positioning tag 42 is installed on the vehicle chassis 43. It determines the real-time spatial position of the vehicle positioning tag 42 by exchanging signals with multiple base stations of the UWB positioning base station 6 in real time.
[0091] The power supply assembly 41 is connected to the cable base assembly to provide power to the tunnel wall inspection robot 3.
[0092] It should be noted that the cable 211 in this solution is preferably an electric cable. One end of the cable 211 is connected to the power supply component 41 of the trolley device 4, and the other end is wound around the cable base assembly reel 224 to provide a rope for the tunnel wall inspection robot device 3. The cable 211 in this solution can be used as both a power supply line and a safety rope, which is highly practical and can also reduce costs.
[0093] The sliding hook positioning tag 17, in conjunction with the robot positioning tag 34, enables intelligent cable rope deployment and retraction. Specifically, the control device 5 collects the position coordinates of the rope hanging assembly 21 and the tunnel wall detection robot device 3 in real time. The cable length between the tunnel wall detection robot device 3 and the rope hanging assembly 21 can be calculated from the coordinates. This length is then compared with a preset distance. Based on the comparison result, the control device 5 synchronously controls the rotation state of the reduction motor 2116 and the worm gear motor 225 to achieve intelligent cable rope deployment and retraction.
[0094] As an example, the cable length of the hanging rope assembly 21 and the tunnel inner wall inspection robot device 3 is set to m, and m = 1.2L.
[0095] The rope assembly 21 moves synchronously with the sliding hook positioning tag 17, that is, the spatial position of the sliding hook positioning tag 17 is the position of the rope assembly 21, and the spatial coordinates of the rope device 21 are set as (x1, y1, z1).
[0096] The position of the robot positioning tag 34 is the position of the tunnel inner wall detection robot device 3, and its coordinates are set as (x2, y2, z2).
[0097] The distance between the rope assembly 21 and the tunnel wall inspection robot device 3 ,and .
[0098] The control device 5 determines whether m is greater than 1.2L. If so, it synchronously controls the geared motor 2116 and the worm gear motor 225 to rotate in the first direction and executes the rope winding step until m = 1.2L. If not, it synchronously controls the geared motor 2116 and the worm gear motor 225 to rotate in the second direction and executes the rope unwinding step until m = 1.2L.
[0099] If the tunnel wall inspection robot device 3 remains stationary, the intelligent rope retraction system device 2 can automatically lock the cable, improving the stability of the system operation.
[0100] For example, when the control device 5 calculates that the cable length between the tunnel inner wall inspection robot device 3 and the rope hanging assembly 21 remains unchanged, it determines that the tunnel inner wall inspection robot device 3 is stationary. At this time, the control device 5 synchronously controls the reduction motor 2116 and the worm gear motor 225 to stop rotating, and the intelligent rope winding and unwinding system device 2 can automatically lock the cable, thus improving the stability of the system operation.
[0101] Meanwhile, the sliding hook positioning tag 17, the robot positioning tag 34, and the trolley positioning tag 42 work together to enable the sliding rail device 1 and the transport trolley device 4 to move synchronously with the tunnel inner wall detection robot device 3.
[0102] Specifically, the control device 5 synchronously collects data from the hook positioning tag 17, the robot positioning tag 34, and the trolley positioning tag 42. The spatial position of the slide rail device 1 is consistent with that of the hook positioning tag 17, and its spatial coordinates are (x1, y1, z1). The spatial position of the transport trolley device 4 is consistent with that of the trolley positioning tag 42, and its coordinates are set to (x3, y3, z3). The spatial coordinates of the tunnel inner wall detection robot device 3 are (x2, y2, z2).
[0103] If y1=y2 and y3=y2, then the slide rail device 1 and the transport trolley device 4 remain stationary; if one of them is not equal, then the motors of the slide rail device 1 and the transport trolley device 4 are controlled by the control device 5 until y1=y2 and y3=y2.
[0104] The tunnel wall inspection robot device 3, intelligent rope retraction system device 2, and transport vehicle device 4 are located by UWB positioning base station 6. Based on the coordinates of the positioning tunnel wall inspection robot device 3, the movement of the rope retraction system device 2 and the transport vehicle device 4 is controlled so that the three are on the same longitudinal section of the tunnel. This avoids the need for repeated climbing to safety rope attachment points. The tunnel wall inspection robot can traverse the entire tunnel wall without safety risks and has great potential for widespread application.
[0105] The intelligent safety protection system based on tunnel wall detection provided in this solution avoids the problem of manually climbing up and changing the safety rope attachment point multiple times. The safety rope protection system maintains the same tunnel cross section as the robot's position, automatically retracts and extends the rope according to the robot's position, and has a self-locking function, effectively overcoming the problems existing in the prior art.
