In addition, specialized inspectors are required to record the data. For higher positions on the columns, manual operation is often required, which is inconvenient, inefficient, and also dangerous. Therefore, this invention proposes a non-destructive testing detection device for road and bridges to solve the above problems. Summary of the Invention

The two dual-axis motors are respectively fixedly mounted on opposite sides of two arc-shaped plates. The four active Mecanum wheels are symmetrically arranged in two groups on the two arc-shaped plates. The two active Mecanum wheels on the same arc-shaped plate are located on the upper and lower sides of the corresponding dual-axis motors, respectively. The active Mecanum wheels on the two arc-shaped plates are arranged 180° rotationally symmetrically, and the driven rollers on the active Mecanum wheels on the two arc-shaped plates have opposite inclination directions. The four rotating shafts are rotatably mounted in pairs on the corresponding arc-shaped plates and are axially fixedly connected to the corresponding active Mecanum wheels. The four universal couplings are respectively mounted on the two output shaft ends of the corresponding dual-axis motors, and the four rotating shafts are respectively connected to the corresponding universal couplings for transmission, to compensate for transmission errors and ensure synchronous transmission.

[0007] Preferably, the support drive assembly includes a fixed plate, multiple T-shaped rods, a mounting plate, an electric cylinder, and a sleeve; the fixed plate is fixedly installed on the front side of the mounting box; the multiple T-shaped rods are arranged parallel to each other and fixedly installed on the bottom side of the fixed plate; the mounting plate is slidably installed on the multiple T-shaped rods; the electric cylinder is fixedly installed on the fixed plate, and the telescopic end of the electric cylinder is fixedly connected to the mounting plate; the sleeve is fixedly installed on the mounting plate and parallel to the axis of the electric cylinder, and the non-destructive testing part is detachably installed inside the sleeve.

[0011] Preferably, the non-destructive testing unit is an electronic rebound hammer, used for non-destructive rebound strength testing of the column.

[0012] Preferably, the road and bridge non-destructive testing detection device also includes an auxiliary support component, which is set on two arc-shaped plates and used to cooperate with the trajectory adjustment component to keep the two arc-shaped plates in a stable posture along the outside of the column.

[0014] The beneficial effects of this invention are: This invention achieves fully automated non-destructive testing of columns through the coordinated operation of the mounting box, two arc-shaped plates, support adjustment components, trajectory adjustment components, non-destructive testing unit, and support drive components.

[0015] The worm gear transmission structure used in the support adjustment component utilizes the meshing relationship between the worm and two worm wheels to precisely control the unfolding angle of the two arc plates under the drive of the adjustment motor. This allows the device to adapt to the testing requirements of columns with different diameters. At the same time, the self-locking characteristic of the worm gear ensures the positional stability of the arc plates after adjustment, avoiding angle deviation caused by external forces during the testing process.

[0016] By employing omnidirectional Mecanum wheel movement technology in the trajectory adjustment component, and using two sets of active Mecanum wheels arranged 180° rotationally symmetrically, along with driven rollers with opposite tilt directions, the device can achieve flexible movement and precise positioning along the circumference of the column outside the column. The dual-axis motor drives the rotating shaft through a universal coupling to rotate the Mecanum wheels, effectively compensating for the transmission shaft deviation caused by the curvature of the arc plate, ensuring the synchronization and smooth movement of the four Mecanum wheels. At the same time, the support drive component drives the mounting plate to slide along the T-shaped rod guide through an electric cylinder, driving the non-destructive testing part inside the sleeve to complete the complete testing action of approaching the column, contacting and applying pressure, rebound detection, and retraction and reset. The multi-point guide structure of the T-shaped rod ensures the straightness and stability of the movement trajectory of the detection part.

[0017] The handheld unit establishes a data link with each functional module of the device through a wireless communication protocol. Operators can view the detection data and equipment status parameters in real time through the control panel in a safe area on the ground, and remotely control the device's clamping positioning, lifting and moving, and the entire detection process. The data broadcast function through the speaker further improves the convenience of operation and detection efficiency. The auxiliary support component and the trajectory adjustment component work together to ensure the fit between the curved plate and the column surface while the Mecanum wheel provides the main driving force, preventing the device from deflecting and shaking around the column axis during the detection process.

[0018] The device of this invention has a compact structure and flexible operation, which completely solves the technical problems of low efficiency, high risk and inconvenient data recording in traditional manual high-altitude inspection, and significantly improves the automation level and operation safety of non-destructive testing of road and bridge columns.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Reference Figure 1-8A non-destructive testing (NDT) device for roads and bridges includes a mounting box 1, two arc-shaped plates 2, a support adjustment assembly, a trajectory adjustment assembly, a NDT unit 5, and a support drive assembly. The two arc-shaped plates 2 are symmetrically arranged on the mounting box 1. The support adjustment assembly is mounted on the mounting box 1 and connected to the two arc-shaped plates 2. The support adjustment assembly includes two support shafts 11, two worm gears 12, a worm 13, and an adjustment motor 14. Both support shafts 11 are rotatably mounted on the mounting box 1 and arranged parallel to each other, and each support shaft 11 is fixedly mounted on its corresponding arc-shaped plate 2. The two worm gears 12... Each is fixedly sleeved on the corresponding support shaft 11; the worm gear 13 is rotatably installed in the mounting box 1 and meshes with the two worm wheels 12; the adjusting motor 14 is fixedly installed at the bottom of the mounting box 1 and is connected to the bottom end of the worm gear 13 for transmission. It can adjust the two arc plates 2 to move in opposite directions as needed, so that the two arc plates 2 can adapt well to columns of different diameters. The adjusting motor 14 is a servo motor, which can precisely control the rotation angle of the worm gear 13, thereby realizing the precise adjustment of the unfolding angle of the two arc plates 2, ensuring that the device can adapt to various column structures of different diameters. The trajectory adjustment assembly is symmetrically arranged on two arc-shaped plates 2. The assembly includes two dual-axis motors 32, four active Mecanum wheels 3, four rotating shafts 31, and four universal couplings 33. The two dual-axis motors 32 are fixedly mounted on opposite sides of the two arc-shaped plates 2. The four active Mecanum wheels 3 are symmetrically arranged in two groups on the two arc-shaped plates 2. Two active Mecanum wheels 3 on the same arc-shaped plate 2 are located on the upper and lower sides of the corresponding dual-axis motor 32. The active Mecanum wheels 3 on the two arc-shaped plates 2 are arranged 180° rotationally symmetrically, and the driven rollers on the active Mecanum wheels 3 on the two arc-shaped plates 2 have opposite inclination directions. The four rotating shafts 31 are rotatably mounted in pairs on the corresponding arc-shaped plates 2 and axially fixedly connected to the corresponding active Mecanum wheels 3. The four universal couplings 33... The couplings 33 are respectively installed at the two output shaft ends of the corresponding dual-axis motors 32, and the four rotating shafts 31 are respectively connected to the corresponding universal couplings 33 for transmission. This is used to compensate for transmission errors and ensure synchronous transmission. It can control the two active Mecanum wheels 3 on the same arc plate 2 to rotate in the same direction as needed. By adjusting the speed difference and rotation direction of the two dual-axis motors 32, the device can achieve multi-track movement such as axial lifting, circumferential rotation and spiral ascent along the column by utilizing the omnidirectional movement principle of the active Mecanum wheel 3. This allows for adjustment of the detection position of the non-destructive testing unit 5. The dual-axis motors 32 are servo motors, which can accurately control the speed and direction of rotation. Combined with the omnidirectional movement characteristics of the active Mecanum wheel 3, the device can achieve flexible and varied movement trajectories on the column surface to meet the position adjustment requirements under different testing scenarios. The non-destructive testing unit 5 is located on the front side of the mounting box 1 and is used for non-destructive testing of the strength of the column to be tested. The support drive assembly is located on the front side of the mounting box 1, and the non-destructive testing unit 5 is located on the support drive assembly. The support drive assembly includes a fixed plate 4, multiple T-shaped rods 411, a mounting plate 41, an electric cylinder 42, and a sleeve 412. The fixed plate 4 is fixedly installed on the front side of the mounting box 1. The multiple T-shaped rods 411 are arranged parallel to each other and fixedly installed on the bottom side of the fixed plate 4. The mounting plate 41 is slidably installed on the multiple T-shaped rods 411. The electric cylinder 42 is fixedly installed on the fixed plate 4, and... The telescopic end of the electric cylinder 42 is fixedly connected to the mounting plate 41; the sleeve 412 is fixedly installed on the mounting plate 41 and parallel to the axis of the electric cylinder 42, and the non-destructive testing unit 5 is detachably fixed inside the sleeve 412 by multiple fastening bolts, so as to facilitate the disassembly, calibration and maintenance of the non-destructive testing unit 5. The axis of the sleeve 412 is perpendicular to the outer side of the column to be tested. The support drive assembly can provide effective support for the non-destructive testing unit 5 and control it to perform non-destructive testing operations. In addition, the non-destructive testing unit 5 is preferably an electronic rebound hammer for non-destructive rebound strength testing of the column.

[0024] Based on the above, and referring to Figure 5 As shown, the road and bridge non-destructive testing detection device also includes a handheld unit 6, which is equipped with a second communication module 61. The two dual-axis motors 32, the adjusting motor 14, and the electric cylinder 42 are each equipped with a third communication module 7. The non-destructive testing unit 5 is equipped with a first communication module 52. The first communication module 52, the second communication module 61, and the third communication module 7 establish a communication connection based on a wireless communication protocol. The second communication module 61 acts as the control center, establishing bidirectional communication links with the first communication module 52 and the third communication module 7 based on the wireless communication protocol to achieve command issuance and data feedback. This is used to enable the handheld unit 6 to control the adjusting motor 14... The device features remote control and data transmission for the dual-axis motor 32, electric cylinder 42, and non-destructive testing unit 5. A control panel 63, electrically connected to communication module 61, is mounted on the handheld unit 6. The control panel 63 integrates a display screen to show real-time test data transmitted from the non-destructive testing unit 5. It also displays the device's battery level, communication signal strength, and the unfolding angle parameters of the two curved plates 2, allowing operators to fully understand the equipment's operating status. Additionally, a speaker 62, electrically connected to the control panel 63, is mounted on the handheld unit 6 to broadcast the received test data, facilitating manual recording by the testing personnel.

[0025] Communication module 2 (61), communication module 1 (52), and communication module 3 (7) preferably adopt a dual-mode communication scheme of low-power Bluetooth module and Wi-Fi. The Bluetooth module is used for short-range fast pairing and basic command transmission, while the Wi-Fi module is used for high-speed data backhaul and remote control. The two communication modes can be automatically switched or manually selected according to the field environment to ensure a stable communication link in complex electromagnetic environments. The communication protocol adopts a custom encrypted frame structure, which includes device authentication, data verification, and retransmission mechanisms to prevent unauthorized device access and data transmission errors.

[0026] Based on the above, and referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the non-destructive testing detection device for roads and bridges also includes an auxiliary support assembly 21, which is set on two arc-shaped plates 2. The auxiliary support assembly 21 includes at least two driven Mecanum wheels, which are located on both sides of the plane where the four active Mecanum wheels 3 are located. The driven Mecanum wheels and the active Mecanum wheels 3 form a three-dimensional support structure to prevent the device from swaying radially along the column and to achieve stable movement in conjunction with the driving force of the active Mecanum wheels 3.

[0027] Based on the above, in order to provide shielding and protection for the dual-axis motor 32 and the universal coupling 33, and to avoid interference from foreign objects, refer to Figure 1-4 As shown, protective shells 201 are fixedly installed on the sides of the two arc-shaped plates 2 that are far apart from each other, and the dual-axis motor 32 and the universal coupling 33 are both located inside the protective shells 201.

[0028] In this embodiment, the control panel 63 may also integrate a directional control rocker for adjusting the speed and direction combination of the two dual-axis motors, thereby controlling the device to move axially, rotate circumferentially, or move along a spiral trajectory along the column.

[0029] Working principle: In use, the device is first moved to the vicinity of the column to be tested. The operator starts the adjustment motor 14 through the control panel 63 on the handheld part 6. The adjustment motor 14 drives the two worm wheels 12 and the two support shafts 11 to rotate synchronously in opposite directions through the worm gear 13, so that the two arc plates 2 gradually unfold. After the two arc plates 2 are unfolded, they are placed on the outside of the column to be tested. Then, the adjustment motor 14 is controlled to rotate in the opposite direction, so that the appropriate clamping angle can be adjusted according to the actual diameter of the column, so that the four active Mecanum wheels 3 and the driven Mecanum wheels in the auxiliary support assembly 21 maintain effective contact with the column surface, thus completing the initial positioning and installation of the device.

[0030] Subsequently, the operator issues a movement command via the directional control joystick on the control panel 63. Communication module 2 61 sends the control signal to communication module 3 7. The two dual-axis motors 32 operate at specific speeds and directions according to the command. Through the universal coupling 33, they drive the rotating shaft 31 to drive the active Mecanum wheel 3 to rotate. Utilizing the omnidirectional movement characteristics of the Mecanum wheel, the device can achieve various movement trajectories such as axial lifting, circumferential rotation, or spiral ascent along the column surface, moving the non-destructive testing unit 5 to the predetermined testing height and orientation. After the device reaches the target testing position, the dual-axis motors 32 stop operating. The self-locking characteristics of the worm gear ensure that the arc plate 2 maintains its current unfolding angle, preventing angle deviation during the testing process. At the same time, the braking function of the dual-axis motors 32 can prevent the device from sliding down the column.

[0031] Next, the electric cylinder 42 receives a control signal from the handheld unit 6, and its telescopic end pushes the mounting plate 41 to slide along multiple T-shaped rods 411 toward the column, causing the non-destructive testing unit 5 inside the sleeve 412 to approach the column surface until the impact rod of the electronic rebound hammer contacts the column surface and applies the specified impact energy, completing one rebound strength test. After one test is completed, the mounting plate 41 is driven to reset by the electric cylinder 42, causing the non-destructive testing unit 5 to withdraw from the column surface and prepare for the next test. During this process, the non-destructive testing unit 5 transmits the test data back to the handheld unit 6 in real time through the communication module 52. The display screen of the control panel 63 simultaneously displays parameters such as rebound value, test position coordinates, device power and signal strength, and the speaker 62 simultaneously broadcasts the test data, which is convenient for ground operators to record and verify.

[0032] After the inspection at one location is completed, the operator moves the device to the next inspection point using the directional control joystick, repeating the above inspection process until multi-point non-destructive testing is completed across the entire height range of the column. After the inspection is completed, the adjusting motor 14 drives the two arc-shaped plates 2 to unfold to their maximum angle, and the device is removed from the column, completing the inspection operation.

[0033] The foregoing has provided a detailed description of the non-destructive testing and detection device for roads and bridges provided by this invention. Specific embodiments have been used to illustrate the principles and implementation methods of this invention. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this invention.
