[0028] Please see Figures 1 to 3An embodiment of the present invention provides a tunnel suspended column detection system 100. The detection system 100 includes a vehicle module 10, a positioning module, a position adjustment module 20, and a detection module 30. The vehicle module 10 is used to travel along the track extension direction in the tunnel 300. The positioning module is used to locate the position of the vehicle module 10. The position adjustment module 20 is installed on the vehicle module 10 and can rotate and adjust its position in the vertical and horizontal directions. The position adjustment module 20 includes a manipulator 21. The detection module 30 includes a visual theodolite set on the vehicle module 10 and a visual detection unit 31 set on the manipulator 21. The visual theodolite is used to detect the inclination of the suspended column 200 in the tunnel 300, and the visual detection unit 31 is used to detect the appearance of the suspended column 200.
[0029] It is understood that the positioning module accurately positions the vehicle module 10 so that it can precisely drive to the detection position of the suspended column 200. Subsequently, a visual theodolite is used to detect the tilt of the suspended column 200. The position adjustment module 20 adjusts the visual detection unit 31 so that the visual detection unit 31 can accurately move to the detection position and detect whether the appearance of the suspended column 200 is damaged. Through the cooperation of the positioning module, the position adjustment module 20 and the detection module 30, automatic positioning, driving and detection are integrated in the tunnel 300, improving construction safety and detection accuracy.
[0030] In one embodiment, the positioning module includes a data analysis unit capable of receiving engineering data and locating the position of the suspension column 200 based on the engineering data. By configuring the data analysis unit to accurately locate the vehicle module, the detection system 100 gains the ability to precisely locate the vehicle module both inside and outside the tunnel 300, facilitating the positioning and implementation of the optimal path planning.
[0031] The positioning module also includes multiple visual theodolites placed at the entrance of tunnel 300 and inside tunnel 300. It should be noted that there are multiple visual theodolites. Among them, the visual theodolite installed on the vehicle body module 10 is used to detect the tilt of the hanging column 200. The other multiple visual theodolites placed at the entrance of tunnel 300 and inside tunnel 300 can cooperate with the visual theodolite installed on the vehicle body module 10 to locate the moving position of the vehicle body module 10.
[0032] In this embodiment, the engineering data includes CPII, CPIII, and construction drawings. CPII mainly provides a benchmark for surveying and offline engineering; CPIII mainly provides a benchmark for track laying and line maintenance; and the construction drawings provide track path information so that the data analysis unit can plan the optimal path based on the construction drawings, avoid detours, and improve detection efficiency.
[0033] In one embodiment, the detection system 100 further includes a control module with an interlock safety mechanism. The interlock safety mechanism enhances the operational safety of the detection system 100, preventing collisions caused by human error.
[0034] In one embodiment, the control module includes a data storage unit and a data transmission unit. The data storage unit can store the data collected by the detection system 100, and the data transmission unit can transmit the data collected by the detection system 100.
[0035] In one embodiment, the control module includes a remote monitoring unit. Based on a 4G / GSM network, the remote monitoring unit is capable of remotely monitoring the detection system 100 of the suspended column 200 within the tunnel 300 in real time. The development of the remote monitoring unit is based on the 4G / GSM network, centrally integrated into the intelligent construction site management terminal, and simultaneously supports remote real-time monitoring of the device, facilitating equipment maintenance.
[0036] In one embodiment, the control module further includes a remote control unit. The remote control unit is developed based on short-range wireless communication, supports remote control of equipment at the construction site, reduces the labor intensity of on-site construction personnel, and improves construction safety.
[0037] In one embodiment, the position adjustment module 20 includes a rotating mechanism 22, a lifting mechanism 23, a lateral movement mechanism 24, and a robotic arm 21. The rotating mechanism 22 is mounted on the vehicle body module 10. One end of the lifting mechanism 23 is connected to the rotating mechanism 22, and the other end of the lifting mechanism 23 is connected to the lateral movement mechanism 24. The robotic arm 21 is mounted on the lateral movement mechanism 24. The rotating mechanism 22 can drive the lifting mechanism 23 to rotate. The lifting mechanism 23 can extend or retract along its own height direction to drive the lateral movement mechanism 24 and the robotic arm 21 to perform lifting and lowering movements. The robotic arm 21 can also move laterally under the drive of the lateral movement mechanism 24. The robotic arm 21 itself has multiple joints, which can flexibly move and drive multiple functional components at the end of the robotic arm 21 to move. Adjusting the position through the position adjustment module 20 facilitates more accurate detection.
[0038] In one embodiment, the detection module 30 further includes an ultrasonic flaw detection unit 32 and an electromagnetic ultrasonic detection unit 33, which are mounted on the robot arm 21. The ultrasonic flaw detection unit 32 is used to detect internal damage to the bolts of the hanging column 200, and the electromagnetic ultrasonic detection unit 33 is used to detect the preload of the nut of the hanging column 200.
[0039] Among them, the ultrasonic flaw detection unit 32 adopts phased array full-focus 3D real-time imaging, which can intuitively display the internal damage of the bolt. The electromagnetic ultrasonic detection unit 33 adopts the dual-wave method of electromagnetic ultrasonic technology. It utilizes the characteristic that the sound velocity changes with stress when the ultrasonic wave propagates in the bolt. By measuring the time change of the ultrasonic wave propagation in the bolt, the preload of the bolt can be indirectly calculated.
[0040] In one embodiment, the vehicle module 10 has a driver's cab and a control room. The vehicle module 10 is a flatbed vehicle capable of automatic movement and has the function of automatic movement on track sections.
[0041] In addition, based on the ballastless track slab and the spacing between the two lines on site, it is ensured that 200mm hanging columns can be installed within a 4.5m x 4.5m area of the machinery. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the patent protection scope of the present invention should be determined by the appended claims.
